Description

Technical Field

[0001] The present invention relates to the technical field of online monitoring of power transmission, and in particular to a low-power consumption wake-up monitoring system, method, device and storage medium for power transmission lines. Background Art

[0002] There is no reliable power supply around the installation site of the transmission line monitoring device, and it is difficult to obtain electricity. It can only be powered by solar energy and batteries. Solar power is greatly affected by the weather. If there are continuous rainy days or heavy snow days, solar energy and batteries cannot support the device for a long time, causing the transmission monitoring equipment to lose power and disconnect, seriously affecting the transmission line equipment and channel monitoring, and thus causing difficulties in the operation and inspection of the transmission line. Therefore, the current transmission line monitoring device adopts the working mode of "periodic photo sleep + manual wake-up capture" to reduce the average power consumption of the monitoring device and relieve battery pressure.

[0003] The working mode of periodic photo taking and sleeping + manual wake-up introduces a communication mechanism of periodic sleep. The longer the sleep time, the lower the average power consumption and the less pressure on the battery. However, this method cannot know the status of the power transmission line and the environment during sleep. If there are safety hazards such as fire at this time, it is impossible to know and locate the hazards in time and take corresponding preventive measures. Although it is possible to capture photos by manually waking up the monitoring device, the premise is that the monitoring personnel have been checking the platform data and can manually wake up the monitoring device after actively discovering the abnormality. This not only increases the work pressure and work intensity of the monitoring personnel, but also has certain risks and time differences in detecting hidden dangers. Summary of the invention

[0004] Purpose of the invention: The purpose of the present invention is to provide a low-power wake-up monitoring system, method, device and storage medium for power transmission lines, which integrates a low-power unit, combines wireless sensors and wireless aggregation nodes, and senses the status of the power transmission environment and the line body in real time, so as to realize real-time wake-up of the monitoring device under abnormal conditions.

[0006] After the wireless sensor collects environmental data and line data, it is sent to the Lora module through the wireless aggregation node module or directly; the Lora module sends the summarized data to the edge computing module for analysis, and the logic judgment module compares the analyzed data with the safety threshold. If it is dangerous, it will be sent to the platform through the 4G / 5G network and a wake-up signal will be sent to the monitoring module through the serial port; otherwise, the analyzed data will be sent to the platform through the 4G / 5G network.

[0007] Furthermore, environmental status monitoring wireless sensors are used to collect temperature, rainfall, humidity, and wind speed data.

[0008] Furthermore, line body monitoring wireless sensors are used to collect data on conductor icing, conductor dancing, conductor temperature and tower inclination.

[0009] Furthermore, the monitoring module is used to exit the sleep state after receiving the wake-up signal, then take pictures, and upload the pictures to the platform through the 4G / 5G network, and then enter the sleep state; the monitoring module will only exit the sleep state and enter the working state when it receives the wake-up signal or reaches the set photo-taking time.

[0010] Furthermore, the platform is used to display the received sensor data and photos; it is also used to set the wake-up working time of the monitoring device, modify the safety threshold of the low-power unit, and modify the data reporting period of the wireless sensor.

[0011] A low-power wake-up monitoring method for a power transmission line described in the present invention comprises the following steps: using wireless sensors to collect environmental data and line body data; summarizing the collected data through a wireless aggregation node module; sending the summarized data to an edge computing module through a Lora module for parsing to obtain specific parameter data, and then sending the parsed parameter data to a logic judgment module; the logic judgment module compares the obtained specific parameter data with a set threshold value, and if dangerous, sends it to a platform through a 4G / 5G network and sends a wake-up signal to the monitoring module through a serial port, and the monitoring module exits the sleep state after receiving the wake-up signal, then takes photos, and uploads the photos to the platform through the 4G / 5G network; otherwise, the specific parameter data is sent to the platform through the 4G / 5G network.

[0012] Furthermore, if the wireless aggregation node module fails, the data collected by the wireless sensors are directly sent to the Lora module and aggregated.

[0013] An electronic device described in the present invention includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the computer program is loaded into the processor, any one of the low-power consumption wake-up monitoring methods for power transmission lines is implemented.

[0014] A storage medium described in the present invention stores a computer program, and when the computer program is executed by a processor, any one of the transmission line low-power wake-up monitoring methods described is implemented.

[0015] Beneficial effect: Compared with the prior art, the present invention has the following significant advantages: the proposed low-power wake-up monitoring device and system for transmission lines integrates a low-power unit on the basis of the traditional monitoring device, combines wireless sensors and wireless aggregation nodes, and senses the status of the transmission environment and the line body in real time under low-power conditions, and realizes real-time wake-up of the monitoring device under abnormal conditions, avoiding the situation where hidden dangers occur during the dormancy period of the monitoring device but cannot be monitored, thereby improving the timeliness of monitoring hidden dangers of transmission lines, which is of great significance to disaster prevention and mitigation.
