Power line deep foundation pit gas monitoring and warning system and method

Abstract

The invention discloses a power line deep foundation pit gas monitoring and warning system and method. The system employs a posture monitoring unit, a heart rate and blood oxygen monitoring unit and a motion monitoring unit to monitor the physical state of an operator, and employs an environment monitoring unit to monitor the information of the environment where the operator is located, the state of the operator is confirmed in multiple modes, an alarm is immediately given for an abnormal condition, and the construction operator is reminded to evacuate safely, so that the construction management operator can grasp the field operation condition in time, and emergency measures such as rescue and evacuation can be carried out conveniently. The system further comprises an emergency rescue unit. The emergency rescue unit comprises a rapid lifting lock catch and a rapid lifting device, wherein the rapid lifting lock catch is arranged above the back of the operator, and one end of the rapid lifting device is connected with the rapid lifting lock catch. The rapid lifting lock catch can be arranged on the back of the safety vest worn by an operator close to the neck and the shoulder, so that the operator can be safely and quickly lifted to a safety zone above the ground level by adopting a quick lifting machine.

Description

technical field [0001] The invention relates to a gas monitoring and alarming system and method for deep foundation pits of power lines. Background technique [0002] Deep foundation pit operation is a common operation scenario in the foundation construction of transmission line engineering. Its risk points include foundation pit collapse, poisonous and harmful gas infringement, falling from high places, object impact, etc. In recent years, the incidence of safety accidents in deep foundation pit operation has been on the rise. . [0003] The deep foundation pit operation site of power grid infrastructure is very dangerous. During the production and construction process, environmental parameters similar to deep foundation pit operations (such as CO, O 2 、CH 4 etc.) Real-time monitoring is very important in the safe construction management process. When an abnormal situation occurs, the construction workers need to evacuate the dangerous area immediately. [0004] However,...

AI Technical Summary

Problems solved by technology

[0004] However, traditional gas monitoring does not have real-time performance, the equipment is bulky and heavy, the data cannot be transmitted to the above-ground operators and remote transmission to the monitoring center, and the alarm method is not timely and intuitive, etc.
