Description

Technical Field

[0001] This utility model relates to a monitoring system, and more particularly to a safety risk monitoring system for power equipment inspection personnel, belonging to the field of power equipment monitoring. Background Technology

[0002] With the continuous construction of new power systems, a massive amount of new power equipment is being connected to the power grid. The working environment faced by power equipment inspection personnel is becoming increasingly complex and diverse. If personnel perform incorrect operations, it can lead to damage to equipment or even trigger cascading failures, causing significant economic losses to the power grid. This places higher demands on the management of operational safety risks for power equipment inspection personnel. Traditional safety risk identification schemes for personnel typically rely on a single video source for judgment. However, given the complex environment of new power systems, a single information source often fails to fully reflect the actual situation at the work site and cannot accurately determine whether the personnel's actions pose a risk.

[0014] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0015] A safety risk monitoring system for power equipment inspection personnel includes multiple data acquisition units, a data transmission module 4, a data processing unit 5, a DDR memory device 6, a controller unit 7, and a display 8. The multiple data acquisition units include a work ticket scanner 2, a work recorder 3 carried by the operator, and a microphone device 1. The output of the data processing unit 5 is connected to the input of the DDR memory device 6. The input of the controller unit 7 is connected to the output of the DDR memory device 6. The output of the controller unit 7 is connected to the display 8 to display the collected data. The microphone device collects verbal communication between the inspection personnel and the monitoring personnel; the work ticket scanner 2 scans images of the equipment inspection work tickets; and the work recorder device records the inspection personnel's work activities. The data transmission module 4 uses the LAN8720A-CP-TR chip as its core. Multiple data acquisition units are connected to the TX+, TX-, RX+, and RX- data pins of the LAN8720A-CP-TR chip via a data bus. The PHY interface of the LAN8720A-CP-TR chip uses four resistors (R129, R130, R131, and R132) to form a differential pair, ensuring stable data transmission. The data processing unit module is connected to the AD-1 converter, and the work ticket recognition module is connected to the AD-2 conversion module. The outputs of both the AD-1 and AD-2 converters are connected to a DDR memory device. The video processing module's output is connected to a photosensitive sensor, acquiring the red, green, and blue channel data from key frames of the worker's work video collected by the video processing module, and storing the digital signals in the DDR memory device via an AD-3 converter. The DDR memory device is based on the MT47H64M16HR chip. The data bus pins of this chip are connected to the processors in the voice processing module, the work ticket recognition module, and the video processing module, respectively, and the processed data is input to the DDR memory device chip through the data bus.

[0016] The following describes the working process of a safety risk monitoring system for power equipment inspection personnel:

[0017] (1) This system collects the work information of equipment inspection personnel through microphones, scanners and work recorders, including the communication of instructions, work task objectives and work behavior of the personnel during the operation.

[0018] (2) The collected data is transmitted to the data processing module via Ethernet. This data transmission module is based on the LAN8720A-CP-TR chip and is connected to the J4 unit in the data transmission module via a network cable. Figure 4The rightmost unit J4 connects to the TX+, TX-, RX+, and RX- data pins. Unit J4 is then connected to the LAN8720A-CP-TR chip via the TXP, TXN, RXP, and RXN data lines for reliable Ethernet communication. Resistors R129, R130, R131, and R132 are used to terminate the differential pairs, preventing signal reflection and ensuring efficient and stable data transmission. VCC3V3, VCC1V2, and ETH3V3 serve as the power input pins for this module, providing power to the entire module. See details... Figure 4 As shown.

[0019] (3) The voice processing module, work ticket recognition module, and video processing module in the data processing unit will process and analyze the collected data. The voice processing module will convert the collected voice signal into a digital signal through an AD-1 converter so that it can be stored in DDR memory. The work ticket recognition module is connected to the AD-2 conversion module to recognize the text information in the work ticket and extract the text information content in the work ticket to obtain the corresponding work requirements and work text content, and store it in DDR memory. The video processing module will first extract the key frames of the collected video of the workers' work in a cycle of 12 frames, and obtain the red, green and blue channel data in the key frames of the video of the workers' work collected by the video processing module through a photosensitive sensor, and store the digital signal in the DDR memory device through an AD-3 converter. The DDR memory device is as follows Figure 2 As shown, pins DDR_DQ0 to DDR_DQ15 in the circuit are the data bus, used to transmit data between the DDR memory and the data processing unit (5) and the controller unit (6). The corresponding processing module will input the processed data into the DDR memory chip through the data bus. Pins DDR_A0 to DDR_A13 are the address bus. DDR_CAS and DDR_RAS respectively indicate whether the address bus signal refers to the column address or the row address. Through the above address signals, the location of the input data stored in the memory chip is determined, and the location in the memory chip from which data should be read is determined. DDR_WE is used to control the read and write capabilities of the DDR memory. Each processing unit is connected to the DDR memory through the data bus. When DDR_WE is high, the processing unit can input data into the DDR memory; when DDR_WE is low, the controller 5 obtains the corresponding data from the DDR memory.

[0020] Furthermore, the focus of this utility model is not on the data processing of the work ticket scanner, the work recorder, and the microphone carried by the operators. The data processing of the above-mentioned devices can be achieved by any known technology to process the collected voice data, video data, and document data scanned by the scanner (such as "Design and Production of Power Room Inspection Robot System Based on Voice Interaction", "A Method and System for Cloud Hidden Recognition of Power Equipment in Inspection Scenarios", "Intelligent Document Processing: Principles and Practices of Automated Document Data Extraction", etc.). The focus of this utility model is on considering uploading the multi-faceted data of video, voice, and documents collected on-site to a remote location (such as a control center) to monitor in real time whether the on-site equipment inspection personnel's operations are compliant.

[0021] (4) The controller (7) extracts the corresponding data from the DDR memory and compares it with the standard operation threshold stored in the database. The controller will compare whether the on-site instruction information is consistent with the information specified in the operation ticket, and whether there is any deviation between the on-site operator's operation behavior and the standard operation behavior, so as to determine whether there is any risk in the operation behavior of the power equipment inspection operator. If there is a risky behavior, the key frame corresponding to the risky behavior video will be transmitted through the DDR memory. Figure 3 The VGA interface shown outputs data to the monitor. Red, green, and blue channel data of the risky behavior are transmitted to pins VGA_R0 / VGA_R1 / VGA_R2, VGA_G0 / VGA_G1 / VGA_G2, and VGA_B0 / VGA_B1 / VGA_B2 of the connector, respectively, and connected to pins 1, 2, and 3 of the DB15F connector. The DB15F connector connects to the monitor, transmitting red, green, and blue video signals to it, thus visually displaying the operator's risky behavior on the monitor.

[0022] This invention collects and processes data from multiple information sources on-site to monitor the actual situation at the work site in real time, thereby accurately determining whether there are risks in the operators' actions.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
