Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to a substation safety control device. Background Technology

[0002] In modern power systems, substations serve as crucial hubs for power conversion and distribution, and their safe and stable operation directly impacts the reliability and stability of the entire power network. With the continuous growth in electricity demand and the expanding scale of power systems, the number of devices within substations is increasing, and their structures are becoming more complex, placing higher demands on the safety management and control of substations.

[0003] Traditional substation safety management relies primarily on manual inspections and some basic monitoring equipment. Manual inspections have several limitations: the varying levels of expertise and work ethic among inspectors can lead to missed or misdiagnosed equipment problems; the long intervals between manual inspections make real-time monitoring difficult and prevent the timely detection of sudden equipment failures. Furthermore, simple monitoring equipment offers limited functionality, monitoring only a few parameters and failing to provide comprehensive, multi-parameter monitoring and analysis of substation equipment.

[0004] Regarding the aforementioned technologies, the inventors discovered the following drawbacks: many existing devices on the market lack flexible mobility systems and are mostly fixed installations, making it impossible for them to move freely between different areas of the substation. They can only monitor devices in fixed locations, making it difficult to fully cover all substation equipment. This results in some devices being in monitoring blind spots for extended periods, increasing the risk of equipment failure. Summary of the Invention

[0007] The inspection vehicle assembly includes a limiting sleeve, a limiting groove, a servo motor, an internally threaded sleeve, a servo turntable, a rotating rod, and an NFC signal receiving module. The limiting sleeve is fixedly mounted on top of the microprocessor. A limiting groove is formed inside the limiting sleeve. The servo motor is fixedly mounted inside the limiting sleeve. The output end of the servo motor is threaded onto the internally threaded sleeve. The servo turntable is movably mounted on the top of the internally threaded sleeve. A rotating rod is fixedly connected to one side of the servo turntable. An NFC signal receiving module is fixedly mounted to one side of the rotating rod.

[0008] Optionally, the inspection vehicle assembly also includes a frame, drive wheels, positioning slots, a microprocessor, a vision sensor, an obstacle avoidance assembly, and a buzzer. The frame is located on one side of the substation control cabinet. The drive wheels are movably mounted on the bottom of the frame. The microprocessor is fixedly mounted inside the frame. The vision sensor is fixedly mounted on one side of the frame. The obstacle avoidance assembly is fixedly mounted on the top of the frame. A buzzer is also fixedly mounted on the top of the obstacle avoidance assembly.

[0009] Optionally, the visual sensor, obstacle avoidance component, and buzzer are all electrically connected to the microprocessor, which wirelessly connects to the terminal processor using the Modbus protocol.

[0010] Optionally, the sensor integration cabinet includes sensor components for collecting data such as temperature, humidity, voltage and current of the substation control cabinet, a processor for processing the data and converting it into digital signals, and an NFC antenna for receiving digital signals in real time.

[0015] 2.

[0021] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.

[0022] This application discloses a substation safety management and control device.

[0023] Please see Figure 1 A substation safety management and control device includes a substation control cabinet 1, a sensor integration cabinet 2 on one side of the substation control cabinet 1, an NFC chip sensing module 3 at the bottom of the sensor integration cabinet 2, and an inspection vehicle assembly 4 on one side of the substation control cabinet 1.

[0024] Please see Figures 2 to 4 The inspection vehicle component 4 includes a limiting sleeve 408, a limiting groove 409, a servo motor 410, an internally threaded sleeve 411, a servo turntable 412, a rotating rod 413, and an NFC signal receiving module 414. The limiting sleeve 408 is fixedly installed on the top of the microprocessor 404. The limiting sleeve 408 has a limiting groove 409 inside. The servo motor 410 is fixedly installed inside the limiting sleeve 408. The output end of the servo motor 410 is threadedly connected to the internally threaded sleeve 411. The servo turntable 412 is movably installed on the top of the internally threaded sleeve 411. The rotating rod 413 is fixedly connected to one side of the servo turntable 412. The NFC signal receiving module 414 is fixedly installed on one side of the rotating rod 413.

[0025] The inspection vehicle component 4 also includes a frame 401, drive wheels 402, positioning slots 403, a microprocessor 404, a vision sensor 405, an obstacle avoidance component 406, and a buzzer 407. The frame 401 is located on one side of the substation control cabinet 1. The drive wheels 402 are movably mounted on the bottom of the frame 401. The microprocessor 404 is fixedly mounted inside the frame 401. The vision sensor 405 is fixedly mounted on one side of the frame 401. The obstacle avoidance component 406 is fixedly mounted on the top of the frame 401. The buzzer 407 is also fixedly mounted on the top of the obstacle avoidance component 406.

[0026] The visual sensor 405, obstacle avoidance component 406, and buzzer 407 are all electrically connected to the microprocessor 404, which uses the Modbus protocol to wirelessly connect with the terminal processor.

[0027] The sensor integration cabinet 2 includes sensor components for collecting data such as temperature, humidity, voltage and current of the substation control cabinet 1, a processor for processing the data and converting it into digital signals, and an NFC antenna for receiving digital signals in real time. The NFC chip sensing module 3 is electrically connected to the NFC antenna and the NFC signal receiving module 414, respectively.

[0028] Limiting blocks are fixedly connected to both sides of the internal threaded sleeve 411, and the limiting blocks are movably connected inside the limiting groove 409.

[0029] The servo turntable 412 is wirelessly connected to the microprocessor 404, and the servo motor 410 is wirelessly connected to the microprocessor 404.

[0030] Further explanation is needed:

[0031] The inspection vehicle component 4 possesses flexible mobility and autonomous operation capabilities. The drive wheels 402 mounted on the bottom of its frame 401 enable the inspection vehicle to move freely within the substation and proceed to designated areas according to preset routes or instructions. The microprocessor 404 inside the frame 401 not only coordinates the operation of the drive wheels 402 but also processes information from the vision sensor 405 and the obstacle avoidance component 406. The vision sensor 405 captures images of the surrounding environment in real time, while the obstacle avoidance component 406 uses various sensing technologies to monitor obstacles ahead. When an obstacle is detected, the microprocessor 404 reacts quickly, adjusting the rotation direction of the drive wheels 402 to achieve autonomous obstacle avoidance, ensuring that the inspection vehicle completes its movement tasks safely and efficiently, and providing a basis for subsequent monitoring work.

[0032] The inspection vehicle component 4 undertakes comprehensive monitoring responsibilities. The vision sensor 405 installed on one side of the chassis 401 can perform detailed inspections of the appearance of equipment such as the substation control cabinet 1, such as observing whether there are any loose parts or surface damage. At the same time, the buzzer 407 on the top of the obstacle avoidance component 406 serves as an alarm device. When an abnormality is detected, it immediately emits a sharp sound to promptly remind the staff to pay attention to potential risks. In addition, through the coordinated work of the NFC chip sensing module 3, NFC antenna and NFC signal receiving module 414, the inspection vehicle component 4 can accurately locate the sensor integration cabinet 2 and interact with it to obtain key operating data such as temperature, humidity, voltage and current of the substation control cabinet 1, so as to achieve in-depth monitoring of the equipment's operating status.

[0033] The inspection vehicle component 4 also possesses precise data interaction capabilities. The structure composed of servo motor 410, internal threaded sleeve 411, servo turntable 412, and rotating rod 413 can drive the NFC signal receiving module 414 to rotate flexibly, realizing multi-angle data acquisition and interaction. Furthermore, the microprocessor 404 adopts the Modbus protocol to wirelessly connect with the terminal processor, enabling timely and accurate transmission of various types of collected data to the terminal processor. This provides strong data support for staff to analyze equipment status and formulate maintenance strategies, thereby ensuring the stable operation of the substation.

[0034] The working principle of the above embodiments is as follows:

[0035] First, the drive wheels 402 at the bottom of the chassis 401 operate under the control of the microprocessor 404, providing the power for the inspection vehicle to move. The microprocessor 404 precisely controls the speed and direction of the drive wheels 402 according to the preset program and the received instructions, so that the inspection vehicle can travel along the planned route in the substation, flexibly shuttle between various devices, and reach the location that needs to be monitored.

[0036] Secondly, the visual sensor 405 and the obstacle avoidance component 406 begin to function. The visual sensor 405 continuously collects image information of the surrounding environment, while the obstacle avoidance component 406 uses ultrasonic, infrared and other sensing technologies to monitor surrounding obstacles in real time. These sensors quickly transmit the collected data to the microprocessor 404, allowing the microprocessor 404 to have a comprehensive understanding of the environmental conditions around the inspection vehicle.

[0037] Next, when the inspection vehicle approaches the sensor integration cabinet 2, the NFC chip sensing module 3, NFC antenna, and NFC signal receiving module 414 work together. The sensor components in the sensor integration cabinet 2 collect data such as temperature, humidity, voltage, and current of the substation control cabinet 1. After being processed by the processor and converted into digital signals, the data is sent out through the NFC antenna. With the assistance of the NFC chip sensing module 3, the NFC signal receiving module 414 on the inspection vehicle accurately receives these signals and completes the data acquisition.

[0038] Next, the microprocessor 404 comprehensively processes and analyzes the collected visual image data, obstacle avoidance data, and data from the sensor integration cabinet 2. Through preset algorithms and models, it determines whether there are any abnormalities in the equipment, such as excessive temperature or loose parts, and generates corresponding analysis results.

[0039] Finally, the microprocessor 404 uses the Modbus protocol to communicate wirelessly with the terminal processor, transmitting the processed monitoring data and analysis results to the terminal processor in real time. This allows staff to remotely monitor the operating status of the substation equipment. At the same time, once an abnormality is detected, the buzzer 407 on top of the obstacle avoidance component 406 immediately sounds an alarm, reminding on-site staff to handle the situation promptly and ensuring the safe and stable operation of the substation.

[0040] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
