Description

TECHNICAL FIELD

[0001] The utility model belongs to intelligent monitoring technical field, specifically disclose a kind of connection architecture of intelligent monitoring module box. BACKGROUND

[0002] With the continuous improvement of intelligent power plant and power station function, the complete collection and processing of local equipment information, the overall planning and unified management of intelligent monitoring equipment are the development trend. However, in engineering practice, part of the local equipment information is in the state of not being collected, and part of the information is provided by the local control box brought by the manufacturer. It does not have perfect I / O data collection function, does not support data local processing, and the field does not have programmable function and standardized communication interface. The intelligent operation and maintenance, fault diagnosis and man-machine interaction of the equipment cannot be realized, and the overall intelligent degree is low, which is difficult to effectively support the intelligent power plant and power station.

[0003] In order to implement local fault diagnosis and maintenance as much as possible, some power plants and power stations try to intelligently transform the field equipment, which directly leads to the reconnection of multiple data lines from the power plant and power station monitoring and management system to the field equipment. It is also difficult for maintenance personnel of different systems in the field to make fault or hidden danger prediction on the stacked various data, therefore, under the premise of not needing large area line transformation, how to design a module to timely classify and process the field data flow, combined with historical data to assist the field maintenance personnel to make relatively accurate diagnosis, so as to improve the response speed and effect of maintenance is a problem to be solved by the skilled in the art.

[0004] To solve the technical problems listed in the background art, the utility model provides a kind of connection architecture of intelligent monitoring module box, and the specific technical scheme is as follows:

[0005] It includes data processing unit integrated with programmable chip in box, bus communication module, I / O acquisition module, Bluetooth communication module, power interface and handheld management terminal located outside the box, wherein, data processing unit is built-in expert system, and is connected with bus communication module, I / O acquisition module, Bluetooth communication module through box communication bus COM port respectively, for sorting, analyzing and diagnosing the collected monitoring data;The power interface provides external power supply for the intelligent monitoring module box;I / O acquisition module is used for collecting monitoring data of field equipment, and is electrically connected with sensor or control cabinet in the field of equipment;Handheld management terminal is wirelessly connected with Bluetooth communication module.

[0006] Preferably, the bus communication module communicates with other intelligent monitoring module boxes and centralized monitoring and management system through PROFITBUS-DP field bus communication port and transmits information.

[0007] The connection mode supports standardized interfaces and communication protocols, and supports multi-dimensional information measurement sensing.

[0008] Preferably, the I / O acquisition module comprises a DI switching value module, an AI analog value module and an RTD thermal resistance module.

[0009] Preferably, the man-machine interface of the handheld management terminal comprises state display, state evaluation, fault diagnosis and maintenance suggestion.

[0010] The architecture has the functions of measurement digitization, information networking and state visualization.

[0011] Preferably, each field device is configured with one intelligent monitoring module box, and a plurality of intelligent monitoring module boxes within a distance of 50 meters are connected in series through a bus communication module, and then communicate with the centralized monitoring and management system through a PROFITBUS-DP special communication plug of one of the module boxes.

[0012] The connection mode reduces a large number of communication lines and saves the reconstruction cost.

[0013] Preferably, one handheld management terminal can connect a plurality of intelligent monitoring module boxes through Bluetooth.

[0014] The plurality of devices in the same functional area are usually supervised by the same professional maintenance personnel, so that different handheld management terminals correspond to different functional areas, on the one hand, avoiding that each device is equipped with one handheld management terminal, causing waste, and on the other hand, there is a certain correlation between different devices in the same functional area, and these information is placed in the same handheld management terminal, which can more comprehensively reflect the health state of the whole system, thereby assisting the maintenance personnel to obtain more accurate diagnosis.

[0015] Compared with the prior art, the connection architecture of the intelligent monitoring module box has the following advantages:

[0016] The standardized communication protocol is adopted, multi-dimensional monitoring information is supported in situ sensing, and the expert system built-in the data processing unit is used for auxiliary diagnosis, so that the state evaluation, fault diagnosis and maintenance suggestion of the intelligent monitoring module box and the host device are realized.

[0017] The Bluetooth communication module is used for direct communication with the handheld management terminal, and the operating personnel can check the real-time state of the in-situ device and the comprehensive evaluation result through the handheld management terminal in situ, or can check the related information of all detected devices in the centralized control room through the field bus and the module box.

[0018] Compared to the conventional method of transmitting local information to the power plant and power station monitoring and management system cabinet via cables, this intelligent detection module box is connected to the power plant and power station centralized monitoring and management system only via optical fiber, saving cables and avoiding excessive back-end data processing.
