The disclosure relates to a method and system for at least one of control and monitoring a condition of a technical equipment or plant for a person on-site. The equipment is provided with tags or labels as electronic or visual identifiers and data transmission is provided by electronic communication.
In modern industry facilities, for example, plants or complex equipment, the use of semi-automated or automated production is common. Often a central operation station is provided as well as on site control panels.
Control of an individual apparatus, machine or equipment can be possible from the central operating station using, for example, faceplates, command interfaces or built-in panels on the equipment. Not all equipment can be controlled using local control panels and may need central intervention.
Therefore, the control of the apparatus, machine or equipment while on site may not be possible with the same functionality and detailed information as that can be provided in the central station by, for example, faceplates for command and visualization, configuration, historical information on process values, service history, and the like.
Not all safety preconditions may be known on-site when in front of the equipment to control it properly. The connection to the control station or control station operator, as well as the coordination with the person on site for safe operation, can be complex and misunderstanding and misoperations can occur.
According to modern contractual customs, the maintenance and the service of the respective facility can be observed by its manufacturer who may not be located at the same location as the facility to be controlled and/or monitored but remote from there. Also, an outside-company charged with such work will want the information about the respective equipment.
A method is disclosed for control and remote monitoring of a condition of technical equipment, provided with tags as an electronic identifier, by a processor coupled to a non-transitory memory, the method comprising: identifying technical equipment on-site by a unique ID, and stored data on the tag, and reading sensor data from the equipment; sending a control request for the identified technical equipment from on-site, by a mobile device using a mobile device application, to a central automation system for approval; analyzing the request and data by the central automation system for determining: whether the control request is allowed/authorized; which functionality is allowed via the mobile device; and sending allowed commands to the central automation system for executing commands for the technical equipment.
A system is disclosed for control and remote monitoring of a condition of technical equipment comprising: tags as electronic identifiers provided for the technical equipment, wherein the tags contain sufficient relevant data about a location, a usage rate, a load and load cycles of a respective object; and a communication device for transmission of the data to be sent to a processor arranged as a central automation system via the communication device, the data being sufficient for a central automation system to process the received data for generating appropriate commands for receipt by the electronic identifiers via the communication device.
Exemplary embodiments of the disclosure are explained in more detail below on the basis of the accompanying drawing, in which:
An exemplary embodiment of the disclosure provides a method of allowing a de-centralized but safe and co-coordinated control of a technical equipment while the person to handle these tasks is on site, being approved by the central control station or system and furnished with substantial and sufficient monitoring power and competence for the equipment operation available at the remote plant location.
Exemplary embodiments of the disclosure include appropriate devices for identification, for example, electronically and/or visually, of the respective equipment to be maintained, serviced, and/or monitored as well as for identification of the respective person who is charged with such work.
Consequently, each respective object is being identified by an electronic device (e.g., a processor) reading its specific tag or label including all (e.g., sufficient data) relevant data (e.g., in a memory) about its location, its usage rate, its load and/or load cycles. The respective response can be sent to the central control station or to a central automation system (e.g., a processor) via electronic communication, whereas the received response including the respective data can be processed in the automation system, and the automation system can generate appropriate commands which are received by the respective electronic identifiers (arranged as e.g., a processor) via the electronic communication and executed.
In an exemplary embodiment of the method according to the disclosure:
Step 1: The user identifies the apparatus/machine, while on-site. A unique ID, stored data on the tag and possibly also sensor data are read;
Step 2: A mobile device application sends a control request including the data for identification of the apparatus on site and optionally other data of the identified apparatus to the automation system for approval as well as with regard to the person who is charged to execute these actions.
Data for identification of the person wearing the mobile device and works on site can be sent, too.
Step 3: The request and data are analysed by the central automation system for the following criteria;
Step 4: If control is allowed then the commands, related to configuration, action, and the like, requested are sent to the central automation/control system which is controlling/passing the commands, executing commands for the apparatus/machine.
The steps above in short are:
The short version as shown above can be important when using an operational faceplate which is created on the mobile device thus corresponding approvals are given to operate from this faceplate.
The tags or labels for identification purposes being mentioned before and being fixed to the respective equipment or to the respective person can, for example, be passive RFID (radio-frequency identification) tags or labels as common and barcodes (1D, 2D) as well as NFC-(near field communication) tags, active RFID-tags, wireless sensor node or hybrid tags or labels which can include electronically stored data and information as visually displayable information.
According to an exemplary embodiment of the disclosure, the data to be read from the respective identifier can be transmitted via cable communication, which can be a local area network, a wide area network or a telephone communication line.
In an exemplary embodiment of the disclosure, the data to be read from the respective identifier can be being transmitted by wireless communication interface whereas the wireless communication interface for transmission of data read from the respective identifier can be, for example, WLAN or Bluetooth.
For example, the wireless communication interface can be provided with access points as well as with repeaters to cover the area of the plant.
Exemplary embodiments of the disclosure are directed to a system that can operate according to the methods of exemplary embodiment of the disclosure.
Accordingly such system for control and remote monitoring of the condition of a technical equipment or plant can be provided with tags or labels as electronic identifiers using electronic communication and:
According to an exemplary embodiment of the disclosure, the specific tags or labels for identification can be provided with printed information to be read electronically, for example, barcodes.
An exemplary embodiment of this system according to the disclosure includes the specific tags or labels for identification which are provided with electronic identifiers, for example, active or passive RFID whereas instead of a passive or active RFID the electronic identifier can be, for example, a barcode, or a NCF-tag, or a wireless sensor node. Furthermore hybrid tags can be used as electronic identifier which provides as well visual information by a barcode as an RFID within one tag or label.
An advantage of visual identification is based on the fact that known smartphones equipped with a built-in camera can be used and an RFID reader may not be necessary.
In an exemplary embodiment of this system according to the disclosure, cables can be used for the transmission of the information included in the specific tags or labels from the monitored and/or controlled area to the automation system. Examples can include wide area network (WAN) or a telephone communication line.
In an exemplary embodiment of the system according to the disclosure, the wireless communication can be provided for the transmission of the information included in the specific tags or labels from the monitored and/or controlled area to the automation system.
The wireless communication can be, for example, a wireless local area network (WLAN) or Bluetooth, or mobile telephone communication.

The communication line 26 can also be a wireless connection, for example, a Bluetooth connection or a wireless local area network respectively via radio frequency transmission.
Additionally the following aspects can lead to better features and functionality.
The request containing the apparatus/machine's identifier, sensor data, data stored in the apparatus/machine is passed to a Control Request module 32, which can be a software system with own intelligence such as a rule based expert-system or a case-based system or any other. The module 32 is using input data from the request and all available data in the system 20 and—if desired—data taken from the service system, from other enterprise systems for the installed base, observing as well safety rules as constraints.
The allowed functionality derived from the evaluation of the data is passed to a module 34 which generates a functional and layout description of the user interface to be later shown on the mobile device with controls and visualization functions allowed on the mobile device 12 and for the user 28. This information is sent back to the mobile device 12, for example a proprietary description file, for example, an xml file.
On the mobile device the functional and layout description is passed to an interface generator engine which produces the interface with all functionality and displays it to the user 28.
Elements which could be available to the user are, for example:
OPC is a technology (system and protocol) that allows embedding and/or linking to documents and other objects and thus provides communication between different applications and creation of heterogenous compound documents.
For example, the desired OPC-UA details, for example, server, object, node, are stored in an RFID tag and after reading the data is taken and presented on a mobile device. All functionality such as history, alarms etc. accordingly is available.
