Embodiment Construction

[0016] combined with figure 1 , The device for monitoring the distance between an object and a danger source for high-altitude operations according to the present invention mainly includes two parts: a distance monitoring device and an analysis and alarm device, and a wireless transmission module 4 is installed on these two parts respectively. The distance monitoring device is installed on the protected object, measures the distance between the object and the danger source in real time, and sends the measurement data to the analysis and alarm device. The analysis alarm device obtains the distance between the object and the danger source through the conventional analysis algorithm and displays it through the human-computer interaction interface. When the distance is close to or less than the specified safe distance and reaches the alarm condition, the light and sound alarm is triggered.

[0017] The distance monitoring device includes a distance measurement module 1 installed o...

Abstract

The invention relates to a device for monitoring a distance between an object and a danger source in overhead work. A distance measuring module is composed of five HC-SR04 ultrasonic sensors. The maximum measuring angle of each sensor is 60 degrees and the distance between the object and the danger source is measured by using an ultrasonic distance measuring principle. A signal output end of an analysis control module is connected with a signal input end of an alarming promotion module; the analysis control module is used for processing data acquire by the distance measuring module and comparing the data with a pre-set safety distance; if the data are close to or less than the safety distance, the alarming promotion module is triggered to work. Wireless transmission modules are mounted on the distance measuring module and the alarming promotion module respectively, so that communication functions of the two devices are realized. With the adoption of the device for monitoring the distance between the object and the danger source in the overhead work, a worker can grasp the distance between the object and the danger source in real time, so that the safety of the overhead work is greatly improved.

Description

technical field [0001] The invention relates to a distance monitoring and alarming device, in particular to a device for monitoring the distance between an object and a danger source in high-altitude operations. Background technique [0002] At present, most power grid equipment is erected at high altitude, so when constructing, maintaining and repairing power grid equipment, workers often need to work at high altitude. Working at heights is a relatively dangerous operation method. In addition to ensuring that the staff and the tools used do not fall vertically, it is also necessary to ensure that the staff and the tools and tools used have sufficient safety distance from the source of danger in the horizontal direction. Dangerous sources include hot objects, charged objects, and objects that may move. According to the requirements of the "State Grid Electric Power Safety Work Regulations", the distance between staff and large equipment and the live part must be greater tha...
