Description

Technical Field

[0001] This invention relates to monitoring devices, specifically to a monitoring and early warning device for the interaction of maintenance risks in main and distribution networks. Background Technology

[0002] With the high proportion of new energy access driving the implementation of the dual-layer optimization model of main and distribution network coordination, the maintenance scenario of main and distribution networks presents new characteristics such as multiple new energy access points, complex electromagnetic environment, and dynamic changes in the work area. Traditional monitoring devices have significant technical shortcomings in terms of monitoring coverage accuracy.

[0003] In terms of monitoring coverage accuracy, existing devices lack a flexible angle adjustment structure. For the maintenance areas around new energy power stations with varying elevations, traditional fixed-angle monitoring equipment has a large number of blind spots and cannot fully capture personnel intrusion or illegal operations.

[0004] Existing power distribution network fault protection and monitoring equipment consists of a fixed base, a protective cover, an adjusting base, a camera, and an adjusting assembly. The fixed base is designed as an inverted U-shape with threaded holes at both ends of the top. A lead screw is installed in these holes as a rotating mechanism. One end of the lead screw is connected to a handle, and the other end passes through a groove in the inner wall of the fixed base and connects to a threaded sleeve seat. A movable block adapted to the lead screw is connected to a fixed locking block. The top of the fixed locking block has a semi-circular groove, and a spring telescopic rod cooperates with an arc-shaped limit block to fix the equipment to the power distribution network frame. A protective cover is installed on top of the fixed base, and an adjusting base is installed inside the protective cover. A fixed shell is installed on top of the adjusting base. One end of the fixed shell is equipped with a camera, and the other end is equipped with the adjusting assembly. The adjusting assembly includes a motor, a first gear, a second gear, and a shaft. The motor output end passes through a through hole in the adjusting base and connects to the first gear. The first gear meshes with the second gear fixed on the shaft. One end of the shaft is connected to the bottom of the adjusting base via a bearing, and the other end passes through the adjusting base and connects to the bottom of the fixed shell. The motor drives the gear transmission to rotate the shaft, thereby adjusting the camera angle. The bottom of the protective cover is also equipped with multiple drainage holes for drainage and protection.

[0005] Existing power grid fault protection and monitoring equipment only allows for single-dimensional rotation of the camera angle adjustment, which cannot adapt to the complex maintenance areas of new energy power plants with varying elevations. This results in monitoring blind spots. Furthermore, it lacks anti-interference structures designed for the complex electromagnetic environment of new energy scenarios, and the data transmission link does not consider backup and caching, making it prone to data loss due to network interruptions.

[0006] Therefore, it is urgent to break through the structural limitations of traditional equipment and build a maintenance risk monitoring solution with accurate monitoring coverage. Summary of the Invention

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0039] See Figure 1-8 As shown, the monitoring and early warning device for the interaction of main and distribution network maintenance risks provided in this embodiment includes a flange 1, on which mounting holes 2 are provided.

The RS485 interface can be directly connected to the local area network of the control console to achieve transmission backup. The Flash memory chip can cache monitoring data to prevent data loss when the network is interrupted.

[0041] The base station body 3 is fixedly connected to the top of the first fixed frame 6, and a rain cover 7 is fixedly installed on the first fixed frame 6. The rain cover 7 is conical in shape, and a transmission device 8 is fixedly installed inside the rain cover 7. The transmission device 8 adopts the Qualcomm SDX55 chip module and is mainly used to upload monitoring data to the operation and maintenance console in real time.

[0042] An environmental sensing module 9 is fixedly installed inside the base station body 3. The environmental sensing module 9 includes a temperature and humidity sensor and an electromagnetic radiation sensor. The temperature and humidity sensor is model SHT31, and the electromagnetic radiation sensor is model EM275. An audible and visual alarm 10 is fixedly installed on one side of the top of the base station body 3. The audible and visual alarm 10 is model TMB12A05+LTE-1101J.

[0043] A push rod motor 11, model XTL100, is fixedly installed on the top of the base station body 3. A connecting sleeve 12 is fixedly connected to the top output end of the push rod motor 11. One end of the connecting sleeve 12 is cylindrical and the other end is annular. The connection between the connecting sleeve 12 and the push rod motor 11 is cylindrical, and the other end of the connecting sleeve 12 is annular. A second fixed frame 13 is fixedly connected to the top of the base station body 3. A movable frame 14 is rotatably connected to the second fixed frame 13. A millimeter-wave radar 15, model R24F, is fixedly connected to the movable frame 14. The movable frame 14 includes an I-beam and a rotating shaft. The rotating shaft is fixed on the I-beam.

The high-definition camera is model AR0234, and the infrared fill light is model SFH 4770S. A micro motor 21, model N20, is fixedly installed on one side of the third fixed frame 18. The micro motor 21 drives the shaft of the third fixed frame 18 to rotate, which in turn drives the rotating seat 19 to rotate. The servo motor 16 drives horizontal rotation, and the micro motor 21 drives vertical rotation.

[0045] The working principle of this device is as follows:

[0046] After the device is fixed to the pole or wall via flange 1 and mounting hole 2, the modules work together to achieve risk monitoring and early warning.

[0047] First, the environmental sensing module 9 collects environmental parameters such as temperature, humidity, and electromagnetic radiation. The millimeter-wave radar 15 drives the movable frame 14 to adjust its angle via the push rod motor 11 to monitor personnel entering the dangerous area. The visual monitoring module 20 uses the servo motor 16 to drive the rotating table 17 to rotate horizontally and the micro motor 21 to drive the rotating seat 19 to rotate vertically to identify personnel's unauthorized operations.

[0048] Each monitoring data is transmitted to the data processing device 5. After being acquired, filtered and encapsulated by the STM32H743 microcontroller, it is transmitted to the operation and maintenance console via the network by the transmission device 8. When the signal is weak, it switches to the RS485 interface for backup transmission.

[0049] When a risk is detected, the console triggers a remote early warning, and at the same time, the audible and visual alarm 10 on the top of the base station 3 activates a local audible and visual alarm, forming a complete working closed loop of monitoring, processing, transmission and early warning.

[0050] The triangular prism-shaped base station body 3, together with the flange 1 and the triangular reinforcing rib 4, can withstand typhoon wind pressure and avoid tilting and falling over. The conical rainproof cover 7 provides protection and is suitable for complex outdoor environments.

[0051] The millimeter-wave radar 15 achieves angle adjustment through the push rod motor 11 and the movable frame 14 structure, and the visual monitoring module 20 achieves dual-axis rotation with the help of the servo motor 16 and the micro motor 21, ensuring that there are no blind spots in the maintenance area.

[0052] Multiple transmission links are used, combined with Flash storage chips to cache data, to prevent data loss due to network interruption;

[0053] The environmental sensing module 9 monitors electromagnetic radiation, and the transmission device 8 is designed to resist electromagnetic interference, meeting the electromagnetic environment requirements under the high proportion of new energy access.
