Problems solved by technology

[0006] The defects of the above technologies mainly include: ① Due to the pre-judgment of the state of the spanning frame based on construction experience, it is impossible to make an accurate judgment, which is greatly affected by human subjective factors
②The video surveillance system is used to monitor the construction site conditions, and the specific data of the safety distance of the spatial distribution cannot be accurately measured, and all-round, real-time, and accurate monitoring cannot be achieved

Abstract

The invention discloses a long-distance wireless intelligent monitoring system for straddling frame state, which includes a safety net relative position monitoring module, a cable tension monitoring module, a wireless area warning system, a multi-channel wireless communication data transmission module, a power supply module and a supporting software installed Ground mobile terminal equipment. The ground mobile terminal equipment and the above-mentioned state function modules and systems form a WIFI local area network, and all monitoring data are transmitted to the ground mobile terminal equipment through WIFI communication, and are received, analyzed and displayed on the man-machine interface by the supporting software. The relative position monitoring module of the safety net adopts the method of area array CCD imaging distance measurement to obtain the minimum vertical distance between the safety net and the upper adjacent object, and the minimum horizontal distance between the upper adjacent object and the edge of the safety net. The invention can monitor the state of the spanning frame in real time, accurately and in all directions, and can perform early warning before accidents occur.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of electric power construction safety, in particular to a long-distance wireless intelligent monitoring system for the state of a spanning frame. [0003] 【Background technique】 [0004] During the power transmission and transformation construction of the power grid, the newly-built transmission line often crosses the crossed objects such as the existing high-voltage transmission lines, railways and expressways geographically, and the ground wire of the newly-built transmission line needs to cross the crossed objects. When laying out the ground wire and tight hanging wire of the new line under tension, in order to ensure the safe distance between the ground wire and the spanned object, it is necessary to set up an insulating safety net between the two in advance. The safety net and its supporting devices are collectively referred to as spanning frames. [0005] With the development of power grid con...
