External force invasion monitoring device under three cross points of power transmission line

Abstract

The invention relates to an external force invasion monitoring device under three cross points of a power transmission line. The external force invasion monitoring device under three cross points of the power transmission line comprises a distance measurement module which is used for transmitting and receiving an ultrasonic wave to a monitoring region; an information main control module connectedwith the distance measurement module and used for judging whether external force invasion exists or not according to the time interval between ultrasonic wave transmitting and ultrasonic wave receiving of the distance measurement module and generating a control signal when it is judged that external force invasion exists; and a warning module connected with the information main control module andused for sending warning information under the control of the control signal. According to the invention, the automation and real-time performance of power transmission line inspection can be improved, the labor cost consumption is greatly reduced, the monitoring efficiency and accuracy are improved, and the possibility of misjudgment is reduced.

Description

technical field [0001] The invention relates to the field of intrusion monitoring, in particular to an external force intrusion monitoring device at a three-span point of a power transmission line. Background technique [0002] The three-span point of transmission line refers to the section where the transmission and distribution line crosses the railway, the first-class road and above, and the important transmission channel. In power grid construction projects, the intersection and proximity of transmission lines and important facilities such as railways, highways, and power lines often cause many problems. Construction machinery activities in this area are the main cause of transmission line tripping accidents. The real-time monitoring of external force intrusion under the span can effectively reduce accidents and promote the stable operation of transmission lines. [0003] At present, the monitoring technology of external force intrusion under the transmission line can b...

Problems solved by technology

However, a single sensor often has its own problems, such as the poor warning ability of the acceleration sensor, the distance sensor is easily affected by the non-monitoring target and causes misjudgment, and the image monitoring method based on the camera sensor is often difficult due to the lack of a complete intrusion image data set.
