Abstract

The invention discloses a safety production major hazard source detection system which effectively solves the problem that in the prior art, the construction progress is affected by the maintenance mode that the power of a power source of a construction hoist is insufficient. According to the invention, a temperature detection circuit uses a temperature sensor U1 to detect a temperature signal of the motor, performs subtraction on the temperature signal to obtain a first difference signal, compares the first difference signal and starts the power calculation circuit; a power calculation circuit performs subtraction operation on the power signal to obtain a second difference value signal, and judges the second difference value signal; and the second difference signal and the power signal are transmitted to a signal transmission circuit at the same time, so that the signal transmission circuit is started; a signal output circuit compensates the power signal by using the second difference signal, generates a warning signal and transmits the warning signal to a control center through the signal transmission module, and safe production is ensured.

Description

technical field [0001] The invention relates to the field of safe production, in particular to a detection system for a major danger source in safe production. Background technique [0002] Safe production has always been the theme advocated by our country, and it is the same in construction sites. The "Regulations on the Administration of Safety Production of Construction Projects" stipulates a variety of major hazards on the construction site, including the construction of deep foundation pits, shafts, and large-scale pipe trenches in foundation engineering, and large-scale mechanical equipment (tower cranes, people-cargo elevators, and construction elevators, etc.) During the installation, dismantling, and use of various lifting and hoisting projects, violations of operating procedures caused accidents such as overturning of mechanical equipment, collapse of structures, and death of people; Irregular operations, command and operation in violation of regulations; irregula...
