On-line monitoring system for strain clamp temperature of transmission line

On-line monitoring system for strain clamp temperature of transmission line

During the long-term operation of high-voltage transmission lines, problems such as surface oxidation and corrosion, loosening of imprisoned bolts, and poor contact contact often occur in fittings and clamps, which cause overheating of the equipment, which leads to fires and large-scale power outages, resulting in major economic losses. Loss and serious social impact. Therefore, real-time temperature monitoring of strain clamps on transmission lines is very necessary. However, due to the high voltage during the operation of the transmission line and the distance from the ground, it is difficult to conduct manual inspections or wire temperature measurement. For a long time, the power operation department lacked effective means for real-time temperature monitoring of high-voltage transmission lines. An online monitoring system for the temperature of strain clamps of transmission lines based on wireless sensor network technology came into being. The on-line monitoring system for strain clamp temperature of transmission lines uses high-precision temperature sensors attached to the wires to collect the temperature of the wires, and sends the collected information to the monitoring center in time through the GSM/CDMA/GPRS or 3G network, so as to realize the detection of the wires. Real-time monitoring of temperature. The system uses high-energy batteries and solar panels + storage batteries for power supply, and according to customer needs, adopts the method of induction to obtain electricity, which is easy to install. After being put into operation, the operation department can timely grasp the heating condition and development trend of the wire, and scientifically arrange the online capacity increase of the transmission line based on this parameter, improve economic efficiency, and improve the safe operation of the line and the level of information management.

Multi-rotor UAV Intelligent Inspection System for Transmission Line

Multi-rotor UAV Intelligent Inspection System for Transmission Line

The function of the multi-rotor UAV automatic driving intelligent inspection system is mainly to realize the automatic driving of the UAV under the premise of ensuring the safety of the transmission line and the safety of the UAV, carry out the fine inspection of the transmission line, and intelligently analyze the operation data, and finally Form a job report. According to the high-precision tower coordinates and height information collected in the early stage, the intelligent terminal of the system can automatically plan the optimal UAV laser modeling flight route, and control the lidar UAV to realize the lidar automatic flight. Upload high-precision laser point cloud data to the aircraft patrol operation platform. The platform automatically plans the drone's refined inspection autopilot route based on intelligent algorithms, and feeds the route feedback to the smart terminal, and then the RTK drone can be controlled for real and automated driving flight. Patrol operations. Upload job data to the machine patrol operation platform. The platform uses artificial intelligence image recognition algorithms to identify and extract job photos, classify defects, rename, and archive, and generate job reports. Transmission line multi-rotor UAV automatic driving intelligent inspection system is mainly composed of three parts, namely intelligent terminal, flight platform and aircraft inspection platform. Among them, the intelligent terminal receives the automatic flight route information sent by the patrol operation platform to realize the intelligent control of the flight platform UAV, and at the same time transmits the operation data to the aircraft patrol operation platform for analysis and processing. The flight platform completes the collection of various operation data and transmits the data to the intelligent terminal and the aircraft patrol operation platform. The machine patrol operation platform plans the autopilot route according to the operation data, and performs post-photo processing.

JC-TLOM900 Transmission Line Crossover Distance Online Monitoring System

JC-TLOM900 Transmission Line Crossover Distance Online Monitoring System

The on-line monitoring system for the crossing distance of transmission lines is mainly composed of a movement mechanism and a measuring device. At the same time, five transmission lines with clear colors (with the background range can be set according to the field of view) are set at equal intervals (the spacing can be set according to the field of view) within the system's field of view. Large difference) feature mark points. The movement mechanism realizes the adjustment, fixation and recovery of the position of the system device on the transmission line, so as to facilitate inspection and maintenance of the staff. The design of the movement mechanism adopts a simple thread-grabbing movement mechanism similar to the line-following robot, which can be remotely controlled. The fixed installation position of the system is the vertical transmission line directly above the crossover position of the overhead transmission line. Since there are fewer obstacles on the line in the middle section of the tower, the accurate adjustment of the position of the measuring device on the transmission line is realized in a rolling manner. The measuring device realizes online monitoring of the crossing distance of transmission lines at different voltage levels, and is mainly divided into five parts: binocular image acquisition unit, embedded system unit, system communication unit, power supply unit, and remote terminal monitoring center.
