Patent Application
20240242585
The present disclosure relates generally to digitizing safety testing processes and, more particularly, to the detection and reporting of unsafe working conditions in enclosed spaces.
When entering an enclosed space in which toxic gases may accumulate, safety protocols require the testing of gas accumulation within the space to determine if the space is safe for an operator to enter. Current practices involve the opening of the enclosed space, such as a telecommunications maintenance hole, and taking a reading near the entrance to the enclosed space to determine the accumulated gas levels within. The majority of the accumulated gas, however, may remain at or near the bottom of the enclosed space, particularly in vertical shafts or holes. As such, the acquisition of readings near the surface or entrance may yield results which are not representative of the gas levels throughout the enclosed space. In some instances, enclosed spaces deemed safe based on current safety practices may expose operators to unsafe levels deeper within the enclosed space. Further, high levels of accumulated gas within enclosed spaces may expose operators to toxic gases while opening the enclosed space, with no internal detection mechanism to warn of these high levels.
Accordingly, a system which may constantly monitor gas accumulation within an enclosed space and communicate the gas accumulation status with an external operator is desirable.
Various details of the present disclosure are hereinafter summarized to provide a basic understanding. This summary is not an exhaustive overview of the disclosure and is neither intended to identify certain elements of the disclosure, nor to delineate the scope thereof. Rather, the primary purpose of this summary is to present some concepts of the disclosure in a simplified form prior to the more detailed description that is presented hereinafter.
According to an embodiment consistent with the present disclosure, a system includes a plurality of gas accumulation sensors each operable to detect a gas within an associated enclosed space, a communications transceiver communicatively coupled to each gas accumulation sensor, and a computer platform operable to execute a gas accumulation application. The gas accumulation application receives one or more readings from each gas accumulation sensor via a communicatively coupled communications transceiver, processes the one or more readings, and alerts an operator with a safety status of the enclosed space.
In a further embodiment, a method includes receiving one or more measurements relating to gas in one or more enclosed spaces from sensors that are each associated with an enclosed space, determining a status of each enclosed space including whether hazardous conditions exist from the one or more measurements, and alerting an operator to the status of each enclosed space. The one or more measurements include a level of accumulated toxic gas, a presence of flammable gas, an oxygen content reading, or any combination thereof.
Any combinations of the various embodiments and implementations disclosed herein can be used in a further embodiment, consistent with the disclosure. These and other aspects and features can be appreciated from the following description of certain embodiments presented herein in accordance with the disclosure and the accompanying drawings and claims.
Embodiments of the present disclosure will now be described in detail with reference to the accompanying Figures. Like elements in the various figures may be denoted by like reference numerals for consistency. Further, in the following detailed description of embodiments of the present disclosure, numerous specific details are set forth in order to provide a more thorough understanding of the claimed subject matter. However, it will be apparent to one of ordinary skill in the art that the embodiments disclosed herein may be practiced without these specific details. In other instances, well-known features have not been described in detail to avoid unnecessarily complicating the description. Additionally, it will be apparent to one of ordinary skill in the art that the scale of the elements presented in the accompanying Figures may vary without departing from the scope of the present disclosure.
Embodiments in accordance with the present disclosure generally relate to digitizing safety testing processes and, more particularly, to the detection and reporting of unsafe working conditions in enclosed spaces. The placement of a sensor near the bottom of an enclosed space may enable more accurate readings of the safety conditions within the enclosed space for operator interaction. The communication between the sensor and the Internet of Things (IoT) may enable a cloud-based platform to monitor conditions within the enclosed space remotely, and may obviate the need to open a potentially unsafe enclosed space for testing. The smart operations enabled by the embodiments disclosed herein may enhance the safety and productivity of maintenance operations within enclosed spaces.
The sensor 102 may be installed within the lower-end of the enclosed space, while a communications transceiver 106 may be installed at or near the entry to the enclosed space 104, such that the communications transceiver 106 may send and receive signals without interference, for example by being obstructed by the structure defining the enclosed space. As such, the sensor 102 and the communications transceiver 106 may be communicatively coupled via a wire 108, which may be a low-voltage cable for the transmission of readings from the sensor 102 to the communications transceiver 106. In some embodiments, the wire 108 may provide power to the gas accumulation sensor 102 from a power source within or near the communications transceiver 106. In further embodiments, the sensor 102 includes a wireless communication component which enables transmission to the communications transceiver 106 without the wire 108.
The communications transceiver 106 may be installed at or near the entry to the enclosed space 104 in order to properly communicate with an intermediate communications system, directly with the internet, or with an independent network forming an IoT. In some embodiments, a LoRa gateway 110 may be within range of the communications transceiver 106, such that the sensor 102 may be in communication with additional devices or servers using a long-range, low-power radio frequency. In at least one embodiment, the LoRa gateway 110 is installed within an existing communications tower 112, such that the power and transmission infrastructure is utilized by the LoRa gateway 110 without the need for additional construction. The LoRa gateway 110, as well as the communications transceiver 106, may enable communication between the sensor 102 and a cloud-based platform 114 which contains or supports a gas accumulation application 116. In some embodiments, however, the communications transceiver 106 may directly or indirectly access the cloud-based platform 114 without the need for the LoRa gateway 110.
The gas accumulation application 116 (hereinafter “the application 116”) on the cloud-based platform 114 may enable the collection, processing, and tracking of data received from the sensor 102 within the enclosed space. The application 116 may receive one or more readings from the sensor 102, via the communications transceiver 106 or the LoRa gateway 110, and may store the readings on a cloud server or other remote device within the cloud-based platform 114. The readings from the sensor 102 may be processed by the application 116 to determine if the conditions within the enclosed space 104 are hazardous based upon predetermined criteria. Further, the sampling rate of the sensor 102 may determine the function of the application 116. In some embodiments, real-time/report-by-exception monitoring of the enclosed space 104 may trigger an alert at any time within the application 116 upon processing the readings. In alternate embodiments, the sensor 102 may monitor the enclosed space 104 with a periodic cycle (e.g., sampling every five minutes) such that the application 116 must wait for the periodic reading in order to determine the conditions within the enclosed space 104.
Once receiving the data within the cloud-based platform 114, the application 116 may determine a real-time status of the enclosed space 104. Further, with an accumulated history of data from the sensor 102, the application 116 may further generate historical trends which may include evaluations of the enclosed space 104 over time. From the data translated into the time-domain, the application 116 may perform further analyses which may show the frequency and speed of hazard events within the enclosed space 104. The application 116 may provide insight into the operation of one or more enclosed spaces 104, such that the most historically hazardous enclosed spaces 104 may be flagged for maintenance, review, or quality control to prevent further hazardous events. The insights provided by the application 116 may include heatmaps of individual enclosed spaces 104, or of all enclosed spaces 104 in a geographic area, to provide a view of the overall conditions within a desired area.
Following the data collection and processing, the application 116 may provide individual readings, tailored results, or a full report of operations to an operator device 118. The operator device 118 may include at least a display 120 which enables an operator to view conditions within the enclosed space 104, receive alerts regarding hazardous conditions within the enclosed space 104, or to view the most problematic enclosed spaces for preventative maintenance. The display 120 on the operator device 118 may display a business intelligence dashboard for the collection and display of data from the application 116.
In view of the structural and functional features described above, example methods will be better appreciated with reference to
The sensor data received at 202 may be immediately processed at 204 in order to determine if hazardous conditions currently exist within the enclosed space. For example, the sensor data may indicate dangerous levels of toxic gas, the presence of flammable gases within the enclosed space, or a low oxygen concentration within the enclosed space, depending upon the sensors installed within the enclosed space. As such, an application (e.g., the application 116) may make the determination of unsafe conditions within the enclosed space, and may provide an alarm or an alert to an operator device (e.g., the operator device 118) at 206.
Regardless of the current conditions of the enclosed space, the sensor data received at 202 may be added to a database stored within a cloud-based platform (e.g., the cloud-based platform 114) such as on a server or other remote computing device which additionally may run the application previously discussed. The database may store the new sensor data as well as a historical record of the sensor data which may date back to include a pre-defined window of time. The stored data may be used at 212 to generate a historical trend using the available data, or to update a previously generated historical trend with the new sensor data received. The historical trend may be visualized in one or more plots or formatted reports such that the frequency of events within the enclosed space, as well as the speed at which the hazardous conditions develop, may be illustrated. The generated visuals for the historical trend, along with the trend data itself, may be output to the operator device at 214 in order to provide insight to an operator regarding the historical status of the enclosed space and possible sources of hazardous events.
From the historical trends generated or updated at 212, further operational insight may be generated by the application at 216. The operational insight may involve a single enclosed space, or may include data from a plurality of enclosed spaces such that a network of enclosed spaces may be analyzed. The operational insight generated at 216 may flag particular enclosed spaces for maintenance, review, or quality control to prevent further hazardous events, based upon the historical trends seen in the individual enclosed spaces and compared to similar enclosed spaces. Further, overall heatmaps of geographical areas may be generated at 216 to provide visualization of present conditions within a network of enclosed spaces, or to show problem areas where hazardous events are more common. The operational insights developed at 216, including the flagging and heatmaps, may be displayed to an operator at the operator device at 218. The output may be directly sent to an operator device at 218, or may be presented in a business intelligence dashboard on the cloud-based platform which may then be accessed via the operator device.
