On line monitoring device for laser protection against external damage of transmission lines
model：DX-WPS100-JG
1、 Demand analysis
In recent years, due to the particularity of the geographical location and environmental conditions of the power lines, there are many tower points, wide areas, and long lines, which are exposed to the wild all the year round. In addition to being attacked by bad natural weather, the probability of power lines being forced to cut off due to human factors, external damage, and theft prevention is on the rise. It is an urgent problem for line management and maintenance units to study countermeasures to prevent power lines from being damaged by external forces and theft prevention, curb accidents caused by human factors, and ensure the safe operation of power grids. The transmission line laser external protection online monitoring device developed by our company can completely solve the problem of external force damage and anti-theft of large construction machinery that can not be found in time during illegal construction operations, greatly reduce the power failure accidents caused by external force damage and anti-theft, reduce the economic losses caused by it, and at the same time, more reasonable and effective staffing can ensure the safe operation of the line.
2、 Working principle
The transmission line laser external protection online monitoring device is installed on the iron tower. With the double detection protection of "laser detector" and "AI video monitoring" installed on the tower, it can detect the intruding objects in the line protection area 24 hours in real time. The processed signals can calculate whether there are vehicles and cranes in the area through the intelligent object algorithm.
Re protection: the "laser detector" installed on the tower detects the superelevation of vehicles and cranes through the intelligent object analysis algorithm, and the on-site device immediately interlocks the audible and visual alarm to prompt that the crane and other foreign matters are close to the high-voltage line, stop the operation, and avoid colliding with the line. At the same time, the 5G/4G wireless warning signal is sent to the central platform, and the alarm receiver can be notified by mobile phone SMS or platform monitoring software. After receiving the alarm, the alarm receiver can immediately open the wireless real-time video through the mobile phone platform or computer platform to check the on-site situation, and can also use the microphone to call for real-time voice in the monitoring center to stop dangerous operations in time.
The second level of protection: the "AI video camera" installed on the tower detects the intrusion of foreign matters such as cranes, intelligently recognizes them, and immediately starts the video recording to prompt the intrusion of foreign matters. The monitoring center uses the microphone to call for real-time voice to stop dangerous operations in time.
3、 Product Functions
(1) Basic configuration of laser protection against external damage: main control unit, video monitoring unit, laser protection against external damage monitoring unit, communication unit, power supply unit, audible and visual alarm, mounting bracket and auxiliary materials.
(2) Laser scanning detection function: subvert the traditional physical external damage protection, use high-precision laser to horizontally scan the safe distance below the line to form a horizontal protection surface. Once the crane drives from the bottom or side, and the superelevation touches the laser surface, the alarm will be started immediately, and the linkage video recording and crane cab will also be linked to alarm to remind the driver to pay attention to the high-voltage line collision; Different from the image recognition algorithm, the laser scanning has a long coverage distance and timely and accurate response, which makes up for the shortcomings of partial errors and false alarms in image recognition. It is a safe and accurate detection method among the current external means,
(3) The front-end AI video identification and analysis function patrols the entire wire gallery. Once there is an intrusion of foreign objects, it can be linked with the monitoring host to prevent external damage and take photos and videos. At the same time, it has 360 ° tour of the entire wire gallery.
(4) Real time video browsing function, resolution ≥ 1080P, can realize real-time video of line corridor, tower base and hidden danger site;
(5) Ambiguous and audible and visual alarm function of remote horn, with remote horn calling, and audible and visual alarm will be started when the object is detected to be too high;
(6) The crane proximity warning function can be linked. When the laser scanning detector detects that a crane has entered, the crane proximity warning device will immediately link to alarm to remind the driver to stop the operation.
(7) It supports the night detection function, can detect and monitor the operation of the transmission line without difference in rainy and foggy weather, and can work 24 hours a day.
(8) The device shall be powered by solar energy and lithium battery, industrial power management module, and efficient solar energy and lithium battery power management scheme to ensure reliable operation of the system.
(9) Support the 4G/5G/WIFI function of all Netcom;
(10) Support grid standard protocol and access to intranet platform;
