Substation high-rise charged body approach-preventing laser safety scanning alarm

Abstract

The invention discloses a substation high-rise charged body approach-preventing laser safety scanning alarm which comprises a high-speed laser ranging sensor, wherein the high-speed laser ranging sensor is connected with an RS232 serial port of a control main board through an RS232 cable; the step motor driver and an executing mechanism are connected with a step drive circuit of the control main board; the step motor and a laser sensor power supply control circuit are connected with the control main board; the wireless remote control data receiving module is connected with the control main board; the buzzer and a construction power supply cutoff control circuit are connected with the control main board; and the battery voltage detection and power supply control circuit is connected with the control main board. According to the alarm, the lifting height of an operating construction machine can be dynamically detected in real time, once the construction machine is detected to exceed the set height limit of a laser safety scanner, audible and visual alarms can be given, and the operating power supply of the construction machine can also be cut off so as to protect the safety of operators and equipment.

Description

technical field [0001] The invention relates to a laser safety scanning alarm device for preventing approaching of high-rise electrified bodies in substations. In particular, it is a laser safety scanner for preventing construction machinery from being too close to high-level electrified bodies in substations. Background technique [0002] Power system safety production is the foundation of power enterprises. Preventing accidental contact with high-level electrified bodies during the operation of substation construction machinery is a difficult and blank point in substation security management. The traditional cover (fence) fence can only solve the safety protection on the front, back, left, and right horizontal planes of construction machinery or personnel, but how to prevent the construction machinery from approaching the high-level charged body above the operating point is the difficulty of protection work. Therefore, it is necessary to develop a three-dimensional prote...

However, when the overhauled equipment under the busbar needs to be hoisted by a crane, such as when the overhauled equipment needs to be replaced, since the boom of the crane will approach the live busbar above when it rises, if the allowable distance between it and the busbar cannot be confirmed, it may lead to The boom is too close to the live busbar and discharges to the boom, resulting in major accidents to personnel and equipment

This is the very big hidden danger in the current power equipment maintenance operation.
