Mining safety helmet with functions of perceiving vital signs and dangerous environment of miners and early warning

Abstract

The invention aims to provide a mining safety helmet with functions of perceiving vital signs and dangerous environment of miners and early warning. The mining safety helmet is formed by a safety helmet shell, a safety helmet liner, a loudspeaker, a human body temperature sensor, a pressure sensor, a methane detection sensor, a carbon oxide detection sensor, an external temperature sensor, an air ventilating opening, a microprocessor, a wireless transmission module, a rechargeable battery, a horizontal speed detection sensor, a vertical speed detection sensor, a gravity induction sensor, a loudspeaker acoustic transmission opening, a power supply switch, a charging interface and a system updating interface. Temperatures, moving speeds, body gestures, head pressure information and underground environment monitoring data of underground personnel can be collected in real time and uploaded. When an accident happens, services are provided for formulating a rescuing scheme according to the collected vital signs and movement state information of the miners; and before the accident happens, early warning can be carried out according to environment monitoring information; and a working condition of the underground personnel can be evaluated according to the personnel movement and the body gesture information under the normal condition.

Description

technical field [0001] The invention relates to a safety helmet used by underground workers, in particular to a mining safety helmet with the functions of sensing miners' vital signs, dangerous environments and early warning. Background technique [0002] Safety helmet is one of the important tools to ensure the life safety of underground workers, and it is a necessary equipment for underground workers. In recent years, mine accidents have occurred frequently in our country, and the success rate of monitoring and early warning of the concentration of dangerous gases and other dangerous factors in the mine before the accident needs to be improved. Moreover, after the accident, the vital signs, moving speed and direction information of the underground personnel cannot be obtained in time. , leading to low effectiveness of accident rescue. On the other hand, during the normal working process of underground personnel, it is necessary to monitor and evaluate the working conditio...
