Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a device for commissioning a handheld monitoring backend in a newly built substation includes a handheld terminal body 1 and a handheld computer 2 connected to the handheld terminal body 1. The handheld computer 2 is used to receive control commands issued by the handheld terminal body 1 and to receive real-time data from the handheld terminal body 1.

[0052] The handheld terminal body 1 is equipped with a wireless communication unit 3, a quantum encryption chip module 4, a lidar scanning unit 5, a signal strength acquisition unit 8, a three-dimensional reconstruction module 12, a multi-target optimization engine 13, an antenna control unit 9, and a power supply module 6. The handheld computer 2 is equipped with a visualization display unit 7.

[0053] The lidar scanning unit 5 is used to perform real-time scanning of the newly built substation and collect raw point cloud data during the handheld movement of the commissioning personnel;

[0054] The 3D reconstruction module 12 is connected to the lidar scanning unit 5 and is used to process the raw point cloud data in real time to build a 3D digital model of the substation on site.

[0055] The multi-objective optimization engine 13, connected to the three-dimensional reconstruction module 12, is used to automatically calculate the optimal deployment positions and corresponding antenna reference orientation parameters of four nodes to be deployed in the three-dimensional digital model based on a preset set of optimization objectives.

[0056] Quantum encryption chip module 4 is used to generate and store quantum keys to perform quantum-level encryption on all wireless communication data;

[0057] Wireless communication unit 3 is used to establish wireless connections with four location nodes deployed on site, receive real-time status data from each node and send lifting control commands to each node;

[0058] The visualization display unit 7 is used to display in real time the four optimal deployment locations, the communication link status of each node, the signal coverage heat map, and the real-time lifting height of each node in the three-dimensional digital model;

[0059] The signal strength acquisition unit 8 is used to acquire the real-time signal strength between the handheld terminal body 1 and the four location nodes.

[0060] The antenna control unit 9 is connected to the wireless communication unit 3 and is used to send lifting control commands to each location node according to the real-time signal strength or the instructions of the debugging personnel to adjust the antenna height and position.

[0061] The power module 6 is used to provide a stable power supply to each unit of the handheld terminal body 1. The power module 6 includes a built-in rechargeable battery, a battery management unit, and an external power interface.

[0062] In this implementation, before debugging, the entire system is connected to the handheld terminal body 1 and the handheld computer 2. Using the laser radar scanning unit 5 integrated in the handheld terminal body 1, the debugging personnel only need to walk normally in the station to collect the cloud data of the entire station in real time. Then, the multi-target optimization engine 13 calculates the best deployment position and matches the strongest signal of the node. The signal strength drive module of the antenna control unit 9 monitors the relationship between the handheld terminal and each node in real time. When the signal strength is lower than the threshold, it automatically sends an upward command to the corresponding node to ensure debugging stability and obtain the screen and data of the monitoring background. After debugging is completed, the handheld computer 2 system automatically generates a complete debugging report.

[0063] Among them, the lidar scanning unit 5 can adopt the Livox Mid-360, a solid-state lidar with a 360°×59° field of view, a detection distance of 40m, and a point cloud output of 100,000 points / second;

[0064] The quantum encryption chip module 4 can use QRNG-100, a miniaturized quantum random number chip with a size of 8mm×8mm, power consumption of <100mW, and a generation rate of 5kbps.

[0065] The signal strength acquisition unit 8 uses an AD9361 or AD9371 integrated transceiver chip with built-in RSSI measurement function, and the measurement range is -120dBm to 0dBm.

[0066] As one implementation method, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the antenna control unit 9 includes multiple antenna bodies 91, and an antenna mount 92 is rotatably mounted on the top of the handheld terminal body 1. The antenna body 91 passes through the antenna mount 92, and a protective cover 93 is movably mounted on the top of the handheld terminal body 1.

[0067] The bottom of the antenna body 91 is equipped with a lifting module, and the bottom of the antenna mount 92 is equipped with a rotating module.

[0068] In this embodiment, the overall system sends lifting control commands to each node through a quantum encryption channel based on real-time signal strength, environmental perception data, or commands input by the debugging personnel via a handheld computer 2. The lifting module adjusts the height of the antenna body 91, and the rotation module adjusts the direction of the antenna mount 92, thereby achieving dynamic adjustment of the antenna height to optimize communication quality.

[0069] As one implementation method, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the lifting module includes a partition 94 installed inside the handheld terminal body 1. A motor 941 is installed on one side of the partition 94. A connecting rod 942 is fixedly connected to the output end of the motor 941. Two sets of bevel gear sets 943 are installed on the connecting rod 942. A lead screw 944 is fixedly installed at the top of the bevel gear set 943. A movable plate 945 is connected to the outside of the lead screw 944. A nut seat is provided inside the movable plate 945. An extension rod 946 is fixedly installed inside the movable plate 945. The top of the extension rod 946 is rotatably connected to the bottom of the antenna body 91. An electric telescopic rod 947 is provided at the bottom of the antenna body 91.

[0070] In this embodiment, the motor 941 drives the connecting rod 942 to rotate, and the bevel gear set 943 on the connecting rod 942 rotates at the same time, driving the lead screw 944 to rotate. The movable plate 945 on the lead screw 944 moves up and down outside the lead screw 944. The movable plate 945 drives the extension rod 946 and the antenna body 91 to move up or down at the same time, thereby realizing the raising and lowering of the antenna.

[0071] As one implementation method, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the rotating module includes a gear disk 95 fixedly installed at the bottom of the antenna mount 92, a toothed plate 96 meshing on one side of the gear disk 95, and an electric telescopic rod 97 installed inside the handheld terminal body 1. The output end of the electric telescopic rod 97 is connected to the toothed plate 96.

[0072] A baffle 81 is installed through the antenna mount 92. A gear plate 82 corresponding to the electric telescopic rod 947 is provided at the top of the baffle 81. A rack 83 is engaged on one side of the gear plate 82. An electromagnet 84 is provided at the bottom of the rack 83.

[0073] The electric telescopic rod 947 has multiple keyways at its end, and the toothed disc 82 has keys inside that correspond to the keyways.

[0074] In this embodiment, when the antenna body 91 needs to rotate and its direction needs to be adjusted, the electric telescopic rod 97 pulls the toothed plate 96 to move, the toothed plate 96 pulls the gear disk 95 to rotate, and the gear disk 95 drives the antenna mount 92 to rotate. When adjusting the direction, the extension rod 946 and the electric telescopic rod 947 of the antenna body 91 are pushed out and inserted into the gear disk 82. The keyway of the electric telescopic rod 947 engages with the key in the gear disk 82. Then, the electromagnet 84 pulls the rack 83 to move. After the rack 83 meshes with the gear disk 82, it drives the antenna body 91 to swing and adjust the angle.

[0075] As one implementation method, such as Figure 1 , Figure 2 , Figure 3 As shown, an LED status indicator unit 10 is also provided on one side of the handheld terminal body 1. The LED status indicator unit 10 is connected to the signal strength acquisition unit 8 and is used to indicate the signal strength between the handheld terminal body 1 and each location node in real time by the flashing frequency of the LED light.

[0076] In this embodiment, the real-time signal strength between the handheld terminal body 1 and the currently selected node is indicated. The flashing frequency is positively correlated with the signal strength; the stronger the signal, the faster the flashing frequency. The LED status indicator unit 10 also includes a red LED light to indicate the device status of the handheld terminal body 1. The device status includes insufficient power and insufficient storage space.

[0077] As one implementation method, such as Figure 1 , Figure 2 , Figure 3 As shown, the multi-objective optimization engine 13 uses a multi-objective genetic algorithm or a deep reinforcement learning algorithm to solve for the optimal deployment positions of the four location nodes and the antenna reference orientation parameters under the spatial constraints of the three-dimensional digital model and the antenna lifting height range constraints.

[0078] In this embodiment, the set of optimization objectives of the multi-objective optimization engine 13 includes maximizing the signal coverage area of ​​the key areas of the entire station, maximizing the received signal strength of the key debugging areas, minimizing the signal overlap area between adjacent nodes, and a cost constraint function based on installation accessibility.

[0080] S1.
