Intelligent personal protective equipment

Description

FIELD

Embodiments relate generally to safety monitoring and more particularly to industrial safety systems employing intelligent personal protective equipment (PPE).

BACKGROUND

Employee health and safety continues to be an area of great importance to employers. Many companies are committed to surrounding employees with a safe working environment to prevent workplace accidents that may otherwise occur. Safety concerns are especially heightened for industrial worksites (often referred to as “industrial plants” or “plants”). Industrial plants include, for example, oil and gas plants, nuclear plants, power plants, and the like. Industrial plants are typically complex systems that include large machinery, electrical systems, flow control systems, or the like. Large machinery can include, for example, turbomachinery, such as turbines, generators and compressors with components rotating at an extremely high rates. Electrical systems can include, for example, power systems that generate and transport high-voltage electrical power. Flow control systems can include, for example, flow control mechanisms, such as valves, pressure vessels and pipes that regulate the flow of high pressure fluids and gas, such as oil and natural gas. Given the complexity of the systems employed, industrial plant systems typically require special attention to safety to minimize the risk of safety incidents, such as physical injuries to persons, damage to the industrial plant systems themselves, and injuries to the environment.

Industrial plants often employ a process control system (PCS) and an industrial safety system (ISS). These systems are normally integrated with one another and are referred to collectively as an integrated control and safety system (ICSS). The PCS typically controls the various processes of industrial plant. For example, a PCS may monitor and control the operations of an industrial plant's systems to provide for the day-to-day operations of the industrial plant, such as the processing of oil and gas. The ISS can include an additional layer of monitoring and control that protects persons, the industrial plant systems and the environment. An ISS may employ safety sensors and controllers that monitor the safety status of the industrial plant and, if needed, initiates action to ensure that any potential and actual safety issues are addressed. As an example, if an ISS detects an exceedingly high pressure within a pressure vessel, the ISS may command the PCS to close an emergency shutdown (ESD) valve (to terminate a fluid supply to the pressure vessel) and command the PCS to open a pressure safety valve (PSV) (to relive pressure in the pressure vessel) to prevent rupturing of the pressure vessel. Industrial safety system can take various forms, such as process safety (or shutdown) systems (PSS) and safety shutdown system (SSS), such as emergency shutdown (ESD) and emergency depressurization-(EDP) systems.

SUMMARY

Applicants have recognized that existing industrial safety systems (ISSs) generally rely on sensing and reacting to physical phenomena, such as measurements of temperature, pressure, flow rate and the like. Although these system can be effective at anticipating and preventing accidents that manifest by way of such physical phenomena, they may not detect or prevent other accidents and near accidents (or “near misses”). For example, existing ISSs may provide an effective means to detect and prevent critical and catastrophic safety events, such as an explosions caused by a high pressure condition; however, existing ISSs may not be effective at detecting and preventing less critical and less catastrophic safety events, such a physical actions of employees that lead to physical injuries, or employee conditions, such as the onset of physical fatigue, that could lead to an accident. Applicants have further recognized that many of these “other” accidents and near misses happen at a relatively high frequency, and although they may not be as individually detrimental as certain catastrophic safety events, taken as a whole, these other accidents and near misses can have a significant impact on industrial plant safety and the wellbeing of employees. For example, a large number of separate injuries caused by physical overexertion of individual employees can have a similar or greater impact than a single critical and catastrophic safety event. Moreover, the detection and prevention of near misses can enhance industrial plant safety by helping to identify and remedy the source of safety events, large and small, before they occur.

Recognizing these and other shortcomings of existing ISSs, Applicants have developed an integrated control and safety system (ICSS) that employs intelligent personal protective equipment (PPE). In some embodiments, sensing devices of an ISS are integrated with PPE that is worn by employees during the course of their work duties. PPE can include safety equipment, such as safety helmets, gloves, safety glasses, shoes, belts and the like that are worn by employees during the course working at an industrial plant. In many instances, persons are mandated to wear these and other types of PPE while in the industrial plant environment. In some embodiments, the sensing devices integrated in an intelligent PPE system worn by a person are employed to collect safety data for the person, including personal health data and/or environmental data.

The personal health data may include biometric health data for the person, such as heart rate, body temperature, brain activity, stress level, physical exertion, blink rate, heart rate, sweat rate, body position and/or the like. The environmental data may include data regarding the environment surrounding the person, such as a geographic location of the person, a temperature at the location of the person, and information for devices proximate to the location of the person. The information for devices proximate to the location of the person can include, for example, information regarding the status, configuration, and operation of devices within communication range of the intelligent PPE. In some embodiments, the personal health data is collected via safety sensors integrated into the PPE or otherwise worn by the person, such as heart rate sensors, body temperature sensors, electroencephalography (EEG) sensors, galvanic skin response (GSR) sensors, pressure sensors, image sensors, and position sensors. In some embodiments, the environmental data is collected via environmental safety sensors integrated into the PPE or otherwise worn by the person, such as temperature sensors, location sensors and communication devices. The communication devices may enable the PPE to communicate with other devices proximate to the location and/or to communicate with an ISS via a network of the ICSS.

In some embodiments, an intelligent PPE device includes intelligent headwear. For example, an intelligent PPE device can include a safety helmet (or “hard-hat”) that includes temperature sensors, EEG sensors, position sensors, location sensors, and/or a wireless communication device integrated therein. In some embodiments, an intelligent PPE device includes intelligent hand wear. For example, an intelligent PPE device can include safety gloves that include temperature sensors, pressure sensors, GSR sensors, heart rates sensors, position sensors, a location sensor, and a wireless communication device integrated therein. In some embodiments, an intelligent PPE device includes intelligent footwear. For example, an intelligent PPE device can include safety boots that include temperature sensors, pressure sensors, position sensors, location sensors, and wireless communication devices integrated therein. In some embodiments, intelligent PPE includes intelligent eyewear. For example, an intelligent PPE device can include safety glasses that include image sensors, temperature sensors, position sensors, a location sensor, and a wireless communication device integrated therein. In some embodiments, an intelligent PPE device includes an intelligent article of clothing. For example, an intelligent PPE device can include a safety belt that includes temperature sensors, position sensors, a location sensor, and a wireless communication device integrated therein. Although certain examples are provided for the purpose of explanation, embodiments can include various combinations of PPE devices and integrated sensors.

In some embodiments, safety data for one or more persons in an industrial plant is collected from intelligent PPEs worn by the one or more persons, and various plant safety operations are undertaken based on the safety data collected. For example, if a critical safety incident (or “safety event”) for a particular portion of the industrial plant is determined from the safety data collected, the ICSS may take steps to shut down operations in that portion of the plant and provide corresponding alerts. In some embodiments, the ICSS for an industrial plant can include several different layers of control and monitoring, and different levels of response can be instituted based on the level of a safety incident. For example, the ICSS can provide feedback to systems for a control room, a superintendent, a safety team, managers and employees that all interact to provide for operation of an ICSS. In the event of a relatively low-level safety incident for a person, the ICSS may provide direct feedback to the person. For example, if the ICSS detects five instances of an employee engaging in poor posture, the ICSS may send a message to the employee. In the event of a relatively high-level safety incident, the ICSS may provide feedback to various portions of the ICSS, and may effectuate an action to remedy the incident. For example, if the ICSS detects a health crisis for a person, such as an elevated heart rate for an extended duration, the ICSS may notify the control room, the superintendent, the safety team, and the person's manager, and may initiate suspension of operations that rely on that person and that could further jeopardize the health of that person, such suspend the operation of machinery under control of the person and/or located near the person.

Further, the integration of industrial internet of things (IIoT) may allow smart devices mounted on plant devices, such as smart sensors mounted on valves, to communicate directly with intelligent PPE devices, such as electrocephalography (EEG) devices in a safety helmet intelligent headwear PPE device. Such a configuration may enable smart devices to wirelessly communicate relevant plant information, such as signals indicative various plant operations and conditions (e.g., inefficiencies in pipeline flow rates, alerts of required maintenance, and corrosion), directly to persons in the plant environment or the ICSS. Such an incorporation of advanced human-machine interface may enhance real-time monitoring and output of the industrial plant.

DETAILED DESCRIPTION

Described are embodiments of systems and methods for integrated control and safety systems (ICSSs) that employ intelligent personal protective equipment (PPE). In some embodiments, sensing devices of an industrial safety system (ISS) are integrated with PPE that is worn by employees during the course of their work duties. PPE can include safety equipment, such as safety helmets, gloves, safety glasses, shoes, belts and the like that are worn by employees during the course working at an industrial plant. In many instances, persons are mandated to wear these and other types of PPE while in the industrial plant environment. In some embodiments, the sensing devices integrated in an intelligent PPE system worn by a person are employed to collect safety data for the person, including personal health data and/or environmental data.

The integration of intelligent PPE and the use of safety data collected by way of the intelligent PPE can enhance the ability of an ICSS to collect relevant safety data across an industrial plant and, in turn, provide improvements in the ability to predict and resolve potential and actual safety incidents. As a result, the integration of intelligent PPE within the ICSS can certainly improve the effectiveness of the ICSS, and improve the safety of the working environment of industrial plants.

FIG. 1 is a diagram that illustrates an industrial plant environment (“industrial plant”) 100 in accordance with one or more embodiments. In the illustrated embodiment, the industrial plant 100 includes an integrated control and safety system (“ICSS”) 102, one or more industrial plant devices 104 and one or more personal intelligent PPE systems (“intelligent PPE systems”) 105 (e.g., including one or more PPE devices 106) communicatively coupled by way of an industrial plant communications network (“network”) 108. Each of the intelligent PPE systems 105 may include one or more intelligent PPE devices 106 worn by a person 110 present in the industrial plant 100, such as an employee working in the industrial plant 100. The industrial plant 100 can include any number of employees wearing an intelligent PPE system 105.

The network 108 may include an element or system that facilitates communication between the entities of the industrial plant 100. For example, the network 108 may include an electronic communications network, such as a local area network (LAN), a wide area network (WAN), a wireless local area network (WLAN), a cellular communications network, the Internet, an industrial network, and/or the like. In some embodiments, the network 108 can include a single network or a combination of networks.

The ICSS 102 can include a process control system (PCS) 120 and/or an industrial safety system (ISS) 122. The PCS 120 may control processes of the industrial plant 100. For example, the PCS 120 may monitor and control the operations of the industrial plant devices 104 to provide for the day-to-day operations of the industrial plant 100 under normal operating conditions. In the context the processing of produced oil and gas, for example, the PCS 120 may control various industrial plant devices 104, such as valves, pumps, and pressure vessels to separate a produced oil mixture into oil, gas and water. The ICSS 102 may include one or more computer systems similar to that of the computer system 1000 described with regard to at least FIG. 6.

The ISS 122 may control safety systems of the industrial plant 100. The ISS 122 may include safety sensors and controllers that monitor the safety status of the industrial plant 100 and, if needed, initiate action to ensure that any potential and actual safety issues at the industrial plant 100 are addressed. If, for example, the ISS 122 detects an exceedingly high pressure within a pressure vessel, the ISS 122 may command the PCS 120 to close an emergency shutdown (ESD) valve (to terminate a fluid supply to the pressure vessel) and command the PCS 120 to open a pressure safety valve (PSV) to prevent rupturing of the pressure vessel. The ISS 122 can take various forms, such as a process safety (or shutdown) systems (PSS) and/or a safety shutdown system (SSS), such as emergency shutdown (ESD) and/or emergency depressurization (EDP) system. In some embodiments, the ISS 122 monitors safety data 130 communicated from intelligent PPE devices 106, processes the safety data 130 to assess the safety status of the industrial plant 100 to identify any potential or actual safety issues (or “incidents”), and, if potential or actual safety issues are identified, takes action to alleviate the potential and/or actual safety incidents and/or alerts one or more entities of the ICSS 102 to the potential and/or actual safety incidents. The ISS 102 may include one or more computer systems similar to that of the computer system 1000 described with regard to at least FIG. 6.

The industrial plant devices 104 can include components for performing and/or monitoring operations of the industrial plant 100. For example, the plant devices 104 can include turbomachinery devices (e.g., turbines, generators, compressors and/or the like of machine systems), electrical system devices (e.g., electrical power generators, batteries, electrical cables and/or the like), flow control system devices (e.g., flow control valves, pressure vessels, pipes and/or the like) and/or sensing system devices (e.g., temperature sensors, pressures sensors, flow rate sensors and/or the like).

The intelligent PPE devices 106 can include PPE devices having safety sensors integrated therein, such as temperature sensors, EEG sensors, pressure sensors, GSR sensors, position sensors, image sensors, heart rate sensors, location sensors, wireless communication devices, and/or the like. An intelligent safety device 106 can be employed to collect safety data 130 for a person wearing the PPE device 106, including personal health data (“PHD”) 132 and/or environmental data (“ED”) 134 for the person 110. Personal health data 132 for a person 110 may include a body temperature for the person 110, brain activity for the person 110, forces exerted by or on the person 110, facial characteristics of the person 110, body position of the person 110, heart rate of the person 110, a blink rate for the person 110, a sweat rate for the person 110, and/or the like. Environmental data 134 for a person 110 may include environmental characteristics for the person 110, such as a geographic location of the person 110, an environmental temperature at the location of the person 110, information for devices proximate to the location of the person 110, and/or the like. In some embodiments, the environmental data 134 includes signals indicative various plant operations and conditions, such as inefficiencies in pipeline flow rates, alerts of required maintenance, and corrosion. In some embodiments, some or all of the environmental data 134 is provided directly to a PPE device 106 from a smart device 111 in the industrial plant 100. A smart device 111 may include, for example, a smart sensor mounted on a valve plant device 104 and adapted to transmit environmental data 134 indicative of operational characteristics of the valve, such as a flow rate through the valve, required maintenance for the valve, and corrosion detected at the valve.

In some embodiments, an intelligent PPE device 106 includes intelligent headwear. For example, an intelligent PPE device 106 can include a safety helmet (or “hard-hat”) that includes temperature sensors, EEG sensors, position sensors, location sensors, and/or a wireless communication device integrated therein. Such an intelligent safety helmet may be capable of sensing safety data 130 for a person 110 wearing the safety helmet, including, for example, personal health data 132 for the person 110 (such as a body temperature at the head of the person 110, brain activity for the person 110, and a body position of the person 110), as well as environmental data 134 for the person 110 (such as a location of the person 110, an environmental temperature near the head of the person 110, and information for industrial plant devices 104 proximate to the location of the person 110).

In some embodiments, the industrial plant 100 includes smart devices 111. A smart device 111 may include a self-contained unit that is capable of collecting, processing and/or transmitting data. For example, a smart device 111 may include a sensor, a processor, a memory, and a wireless transmission device. Such a smart device 111 may, for example, use the sensor to collect environmental data, use the processor to analyze and store the data (in the memory), and transmit relevant information to other devices, such as the raw or processed data, or alerts relating to the data. In some embodiments, smart devices 111 mounted on plant devices 104, such as smart sensors mounted on valves, wirelessly communicate relevant plant information, such as signals indicative various plant operations and conditions (e.g., inefficiencies in pipeline flow rates, alerts of required maintenance, and corrosion), directly to a person 110 in the industrial plant 100 within wireless communication range of the smart device 111. This may be accomplished, for example, by way of wireless communication between the smart device 111 and EEG sensors provided in an intelligent headwear PPE device worn by the person 110. Thus, the person 110 may process relevant plant information received from a smart device 111 by way of the EEG sensors, and take actions to address any issues that are indicated by the information. For example, where a low flow rate, maintenance, or corrosion is indicated for a valve plant device 104, the person 110 may identify such an issued based on the information received from a smart device 111 on the valve by way of the EEG sensors in their intelligent headwear PPE device, and move to the valve plant device 104 to inspect the valve or take an action to remedy the issue (e.g., adjust the valve to increase a flow rate, conduct the required maintenance on the valve, or inspect for corrosion at the valve). The person 110 may report any issues indicated by the information, and any actions taken to remedy the issues, to the ICSS 102 or an entity thereof, such as a superintendent system. Similarly, such a configuration may also enable smart devices 111 to wirelessly communicate relevant plant information to the ICSS 102, for example, by way of an intelligent PPE system 105 within wireless communication range of the smart device 111 and the network 108.

FIG. 2A is a diagram that illustrates an intelligent headwear PPE device 200 in accordance with one or more embodiments. In the illustrated embodiment, the intelligent headwear PPE device 200 includes a safety helmet 201 having a temperature sensor 202, EEG sensors 204, a position sensor 206, a location sensor 208, and a wireless communication device 210 integrated therein. The safety helmet 201 may include a shell 214 and a headband 212 disposed inside of the shell 214. The headband 212 may be arranged to secure the safety helmet 201 to the head of a person wearing the safety helmet 201.

The temperature sensor 202 may be arranged to sense and report a body temperature of a head of a person wearing the safety helmet 201. In some embodiments, the temperature sensor 202 is arranged to contact a head of a person wearing the safety helmet 201. For example, the temperature sensor 202 may be disposed on an interior surface of the headband 212 of the safety helmet 201, such that temperature sensor 202 contacts the head of a person wearing the safety helmet 201.

The EEG sensors 204 may be arranged to sense and report brain activity of a person wearing the safety helmet 201. In some embodiments, the EEG sensors 204 are arranged to contact a scalp of a person wearing the safety helmet 201. For example, the EEG sensors 204 may be disposed on an interior surface of the headband 212 of the safety helmet 201 such that the EEG sensors 204 contact a scalp of a person wearing the safety helmet 201.

The position sensor 206 may sense and report a position of the safety helmet 201 in three dimensional space. Such position information may be used, for example, to determine a position and/or movement of a head of a person wearing the safety helmet 201 relative to other portions of the body of the person, such as the hands, waist, and feet of the person. In some embodiments, the position sensor 206 is disposed on the headband 212 or shell 214 of the safety helmet 201. For example, the position sensor 206 may be disposed on a top/central portion of the headband 212 or shell 214 such that it is located just above the top/central portion of the head of a person wearing the safety helmet 201. Such positioning of the position sensor 206 may provide for sensing and reporting a position of a top/central portion of the head of the person. Such head position information can be useful, for example, for determining an alignment of the head of the person relative to other portions of the person's body.

The location sensor 208 may include a sensor (e.g., a global positioning system (GPS) sensor) for determining a geographic location of the safety helmet 201. Such geographic location information may be used, for example, to determine a geographic location of a person wearing the safety helmet 201. In some embodiments, the location sensor 208 is disposed on the headband 212 or shell 214 of the safety helmet 201. For example, the location sensor 208 may be disposed on an exterior, top/central portion of the shell 214. Such positioning of the location sensor 208 may provide for improved reception of GPS satellite signals. As another example, the location sensor 208 may be disposed on an interior, top/central portion of the shell 214. Such positioning of the location sensor 208 may provide for improved reception of GPS satellite signals, as well as for protection of the location sensor 208 from environmental conditions, such as impacts, rain, and/or the like.

The wireless communication device 210 may include a wireless communication module that is capable of communicating with the network 108, plant devices 104 and/or other PPE devices 106. For example, the wireless communication device 210 may include a relatively long-range communication module that is capable of communicating with the network 108 and/or a relatively short-range communication module that is capable of communicating with plant devices 104 and/or other PPE devices 106. For example, with regard to relatively long-range communication, the wireless communication device 210 may include a Wi-Fi enabled communication module that is capable of communicating with the network 108 via Wi-Fi communication protocols. With regard to relatively short-range communication, the wireless communication device 210 may include a Bluetooth enabled communication module that is capable of communicating with plant devices 104 and/or other PPE devices 106 via Bluetooth wireless communication protocols. Communication with the network 108 may enable the safety data 130 collected via the sensors of the safety helmet 201 to be communicated to the other entities of the industrial plant 100, such as the ICSS 102. Communication with the plant devices 104 may enable the safety helmet 201 to receive device information directly from nearby plant devices 104 and/or act as an intermediary to communicate data between nearby plant devices 104 and other entities of the industrial plant 100, such as the ICSS 102. In some embodiments, the wireless communication device 210 is disposed on the headband 212 or shell 214 of the safety helmet 201. For example, the wireless communication device 210 may be disposed on an exterior, top/central portion of the shell 214. Such positioning of the wireless communication device 210 may provide for improved reception of wireless signals. As a another example, the wireless communication device 210 may be disposed on an interior, top/central portion of the shell 214. Such positioning of the wireless communication device 210 may provide for improved reception of wireless signals, as well as for the protection of the wireless communication device 210 from environmental conditions, such as impacts, rain, high and low temperatures and/or the like.

In some embodiments, an intelligent PPE device 106 includes intelligent hand wear. For example, an intelligent PPE device 106 can include safety gloves that include temperature sensors, pressure sensors, GSR sensors, heart rates sensors, position sensors, a location sensor, and a wireless communication device integrated therein. Such intelligent safety gloves may be capable of sensing safety data 130 for a person 110 wearing the safety gloves, including, for example, personal health data 132 for the person 110 (such as a body temperature at the hands of the person 110, forces exerted on or by the hands of the person 110, electrical conductance of the skin of the hands of the person 110, a heart rate of the person 110, and hand positions of the person 110), as well as environmental data 134 for the person 110 (such as a geographic location of the person 110, an environmental temperature near the hands of the person 110, and information for devices proximate to the location of the person 110).

FIG. 2B is a diagram that illustrates an intelligent hand wear PPE device 220 in accordance with one or more embodiments. In the illustrated embodiment, the intelligent hand wear PPE device 220 includes a pair of safety gloves 221 (including right and left safety gloves 221) each having temperature sensors 222, pressure sensors 224, GSR sensors 226, a heart rate sensor 228, a position sensors 230, a location sensor 232, and a wireless communication device 234 integrated therein. The safety gloves 221 may include a suitable material, such as cloth or leather, for covering the fingers, palm and wrist of a person wearing the safety gloves 221.

The temperature sensors 222 may be arranged to sense and report a body temperature of hands of a person wearing the safety gloves 221. In some embodiments, the temperature sensors 222 are arranged to contact the hands of a person wearing the safety gloves 221. A temperature sensor 222 may be located in one or both of the left and right gloves 221 of the pair of safety gloves 221. In some embodiments, the temperature sensor 222 of a safety glove is disposed on an interior surface of a top side of the safety glove 221 (opposite a palm side of the safety glove 221). Such an arrangement of the temperature sensor 222 may enable the temperature sensor 222 to accurately sense a temperature of a top side of a hand of a person wearing the safety glove 221, without the sensed temperature being skewed by temperature of an item held in or otherwise contacting a palm of the safety glove 221.

The pressure sensors 224 may be arranged to sense and report forces exerted on or by hands of a person wearing the safety gloves 221. In some embodiments, the pressure sensors 224 are arranged to reside between the hands of a person wearing the safety gloves 221 and items contacted by the safety glove 221 (e.g., gripped by the hands of the person wearing the safety gloves 221), such that the pressure sensors 224 can measure a force exerted on or by hands of a person wearing the safety gloves 221. In some embodiments, the pressure sensors 224 of a safety glove 221 are disposed on an interior surface of the safety glove 221 or integrated into the material of the safety glove 221. Such an arrangement may enable the pressure sensors 224 to measure forces exerted on or by hands of a person wearing the safety gloves 221, as well as protect the pressure sensors 224 from environmental conditions, such as rain, high and low temperatures, and/or the like. In some embodiments, the pressure sensors 224 of a safety glove 221 are located at discrete locations about the safety glove 221 to sense forces exerted on or by hands corresponding portions of the hand on which the safety gloves 221 is disposed. For example, the pressure sensors 224 may be located on a palm side of some or all of the five fingers of the safety glove 221 and/or in the palm of the safety glove 221. Such an arrangement of pressure sensors 224 may enable measurement of a gripping force exerted by each of the respective fingers and/or a gripping force exerted by the palm of a person wearing the safety glove 221.

The GSR sensors 226 may be arranged to sense and report skin conductance (or “galvanic skin response”) of hands of a person wearing the safety gloves 221. The electrical conductance of the skin, which varies with its moisture level, may be used, for example, to determine a level of sweating of the person wearing the safety gloves 221. The determined level of sweating can, in turn, be used to identify a stress level of the person wearing the safety gloves 221. For example, a measured increase in the electrical conductance of the skin (measured by the GSR sensors 226 of the safety gloves 221) to a level above a threshold may be used to identify that a person wearing the safety gloves 221 is experiencing relatively high stress. In some embodiments, the GSR sensors 226 of a safety glove 221 are located at discrete locations about the safety glove 221 to sense electrical conductance of the skin of corresponding portions of the hand on which the safety gloves 221 is disposed. For example, the GSR sensors 226 may be located on a palm side of some or all of the five fingers of the safety glove 221 and/or in the palm of the safety glove 221. Such an arrangement of GSR sensors 226 may enable measurement of the electrical conductance of the fingers and the palm of a person wearing the safety glove 221. In some embodiments, the GSR sensors 226 may be located in a portion of the safety glove 221 that can provide a measurement of electrical conductance of the skin, while being protected from environmental conditions, such as impacts or relatively high forces. For example, the safety glove 221 may include only GSR sensors 226 located in the pinkie finger of the safety glove 221, with the expectation that the pinkie finger will experience a relatively low level of impacts and gripping forces when compared to other fingers.

The heart rate sensor 228 may be arranged to sense and report a heart rate of a person wearing the safety gloves 221. In some embodiments, the heart rate sensor 228 of a safety glove 221 may be located in a portion of the glove adjacent the wrist of the person wearing the safety glove 221. For example, the heart rate sensor 228 may include an optical heart rate sensor located in a wrist portion of the safety glove 221. The optical heart rate sensor may include light emitting diodes (LEDs) that are arranged to shine light into the wrist of the person wearing the safety glove 221, and an optical sensor to measure the amount of light that is scattered by blood flow in the wrist of the person. Light may be scattered in a given manner by dynamic changes in blood flow, such as the pulse of flow caused by a beat of the heart and, thus, the measured changes in the light scattering can be used to determine the heart rate of the person wearing the safety glove 221. In some embodiments, the heart rate sensor 228 is arranged to be held near or against the skin of the person wearing the safety glove 221 to enhance the measurement of heart rate. For example, the heart rate sensor 228 may include LEDs and optical sensors located at or near an elastic band 236 of the wrist portion of the safety glove 221 that holds the LEDs and optical sensors near or against the skin of the wrist of a person wearing the safety glove 221.

The position sensors 230 may sense and report a position of the safety gloves 221 in three dimensional space. Such position information may be used, for example, to determine a position and/or movement of the hands of a person wearing the safety gloves 221 relative to other portions of the body of the person, such as the head, waist, and feet of the person. In some embodiments, the position sensor 230 for a safety glove 221 is disposed on a top side of the safety glove 221 (opposite a palm side of the safety glove 221). Such a positioning of the position sensor 230 may help to protect the location sensor 208 from environmental conditions, such as impacts, and gripping forces at the palm side of the safety glove 221. In some embodiments, the position sensor 230 for a safety glove 221 includes a flex sensor arranged to acquire measurements of wrist angle. The wrist angle may be indicative of an angle of the hand relative to the angle of the forearm of the person. In such an embodiment, the position sensor 230 for the safety glove 221 may be disposed proximate the wrist of the person. For example, the position sensor 230 may be on a top side of the elastic band 236 of the safety glove 221.

The location sensor 232 may include a sensor (e.g., a GPS sensor) for determining a geographic location of the safety gloves 221. Such geographic location information may be used, for example, to determine a geographic location of a person wearing the safety gloves 221. In some embodiments, the location sensor 232 for a safety glove 221 is disposed on a top side of the safety glove 221 (opposite a palm side of the safety glove 221). Such positioning of the location sensor 232 may provide for improved reception of GPS satellite signals, as well as for protection of the location sensor 232 from environmental conditions, such as impacts, and gripping forces at the palm side of the safety glove 221.

Communication with the plant devices 104 may enable the safety gloves 221 to receive device information directly from nearby plant devices 104 and/or act as an intermediary to communicate data between nearby plant devices 104 and other entities of the industrial plant 100, such as the ICSS 102. A wireless communication device 234 may be located in one or both of the left and right gloves of the pair of safety gloves 221. In some embodiments, the wireless communication device 234 for a safety glove 221 is disposed on a top side of the safety glove 221 (opposite a palm side of the safety glove 221).

For example, if the ISS 122 identifies relatively minor safety incidents for a person 110 that have occurred less than a threshold number of times, the ISS 122 may provide, to the person 110, an alert indicative of the relatively minor safety incidents; however, if the ISS 122 identifies relatively minor safety incidents that have occurred more than the threshold number of times, the ISS 122 may provide, to the person and other entities of the ICSS 102 (e.g., the control room system, the superintendent, a safety team, and/or the person's manager) an alert indicative of the relatively minor safety incidents. In some embodiments, if the ISS 122 identifies the occurrence of a critical safety incident, the ISS 122 may initiate responsive actions, such as ceasing certain operations of the industrial plant 100 and/or alerting the entities of the ICSS 102 (e.g., including the person, the control room system, the superintendent, a safety team, and/or the person's manager).

FIG. 5 is a flowchart that illustrates a method 500 of operating an industrial plant integrated control and safety system (ICSS) in accordance with one or more embodiments. Method 500 can include monitoring safety data received from PPE devices (block 502). In some embodiments, monitoring safety data received from PPE devices includes the ISS 122 receiving the safety data 130 communicated to the ICSS 102 from one or more intelligent PPE devices 106 of one or more intelligent PPE systems 105, each worn by a person 110 located in the industrial plant 100. For example, referring to the example embodiment of the intelligent PPE system 105 of FIG. 4, monitoring safety data 130 received from PPE devices 106 may include the ISS 122 receiving the sets of safety data 130 generated by each of the intelligent headwear PPE device 200, the intelligent hand wear PPE device 220, the intelligent footwear PPE device 240, the intelligent eyewear PPE device 260, and the intelligent clothing PPE device 270.

The method 500 can include determining whether a critical (or “red flag”) safety incident or moderate (or “yellow flag”) safety incident has occurred (blocks 504 and 506, respectively). In some embodiments, determining whether a safety incident has occurred includes the ISS 122 assessing the received safety data 130 to determine whether a safety incident has occurred at the industrial plant 100. The method 500 can include, in response to determining that no safety incident has occurred (or “white flag” conditions), continuing to monitor the safety data received from PPE devices (block 502). The method 500 can include, in response to determining that a safety incident has occurred, executing a corresponding response (blocks 510 and 512).

In some embodiments determining whether a critical or moderate or minor safety incident has occurred includes the ISS 122 assessing the nature and/or frequency of a safety incident. A critical incident may be defined, for example, as a monitored condition being elevated above a threshold or elevated above 80% of the threshold for a given duration of time. Thus for example, if a heart rate threshold is set at 200 beats per minute and a duration is set to 10 minutes, then the ISS 122 may identify a safety incident as a critical safety incident in response to determining that the safety data 130 indicates that a person 110 has a heart rate above the threshold heart rate of 200 beats per minute or that the person 110 has a heart rate above 160 beats per minute for at least 10 minutes. The method 500 can include, in response to determining that a critical safety incident has occurred, executing a critical incident response (block 510). This can include, for example, ceasing certain operations of the industrial plant 100 and/or alerting the entities of the ICSS 102 (e.g., including the person, the control room system, the superintendent, a safety team, and/or the person's manager). For example, if the ISS 122 determines that one or more employees are experiencing a health crisis in a portion of the industrial plant 100, such as one or more persons 110 experiencing a heart rate above the threshold heart rate of 200 beats per minute, the ISS 122 may initiate suspension of plant operations in that portion of the industrial plant 100, send a corresponding alert to the control room terminals of the control room system 150, send a corresponding alert to the superintendent computer terminal of the superintendent system 152 for presentation to the superintendent that is tasked with overseeing operation of the industrial plant 100, send a corresponding alert to the safety team computer terminals of the safety team system 154 for presentation to personnel of the safety team tasked with overseeing safety of the industrial plant 100, and/or send a corresponding alert to a manager computer terminal of the managerial system 156 associated with the manager for the person 110 for presentation to the manager of the person 110.

A moderate incident may be defined as a monitored condition being elevated above 50% of a threshold for a given duration of time. Thus for example, if a heart rate threshold is set at 200 beats per minute and a duration is set to 10 minutes, then the ISS 122 may identify a moderate safety incident in response to determining that the safety data 130 indicates that a person 110 has a heart rate heart rate above 100 beats per minute for at least 10 minutes. The method 500 can include, in response to determining that a moderate safety incident has occurred, executing a moderate incident response (block 512). This can include, for example, alerting certain entities of the ICSS 102. For example, if the ISS 122 determines that a person 110 is experiencing a moderate health issue, such as the person 110 experiencing a heart rate heart rate above 100 beats per minute for at least 10 minutes, the ISS 122 may send a corresponding alert to the control room terminals of the control room system 150, and send a corresponding alert to the person 110 (e.g., via the intelligent PPE system 105 worn by a person 110 and/or an employee computer terminal associated with the person 110).

FIG. 6 is a diagram that illustrates an example computer system (or “system”) 1000 in accordance with one or more embodiments. The system 1000 may include a memory 1004, a processor 1006 and an input/output (I/O) interface 1008.
