Fire extinguisher air pressure monitoring system based on Hall effect and working method thereof

Abstract

The invention provides a fire extinguisher air pressure monitoring system based on a Hall effect and a working method thereof. The system comprises a fire extinguisher with a barometer, an air pressure monitoring device, a gateway and a server. A pointer of the barometer of the fire extinguisher is a magnetic pointer. The air pressure monitoring device comprises an MCU and at least one Hall element connected with the MCU. The Hall element is arranged near the pointer of the barometer; a corresponding relation table between Hall element output signals and the air pressure of the fire extinguisher is stored in the MCU, and the MCU is used for capturing the output signals of the Hall element, searching a corresponding relation table between the Hall element output signals and the air pressureof the fire extinguisher to obtain corresponding air pressure value of the fire extinguisher and transmitting the air pressure value to the server through the gateway. The linear Hall technology is adopted, additional air guide holes do not need to be additionally formed in the fire extinguisher, structural modification is small, the linear Hall fire extinguisher is compatible with all types of fire extinguishers at present, the appearance is basically not much different from that of traditional fire extinguisher equipment, and operation smoothness is not affected.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to a Hall effect-based fire extinguisher air pressure monitoring system and a working method thereof. Background technique [0002] Traditional fire extinguishers can only judge whether the air pressure of the equipment is normal through the barometer, and the air pressure monitoring can only be carried out through regular personnel inspections, which is not conducive to unified management, and it is difficult to determine the status of the fire extinguisher device. [0003] At present, there has been a device for reporting the position and air pressure of an intelligent fire extinguisher. This device adds an air pressure detection device to the fire extinguisher, and requires the design of a complex air guide structure with a pressure sensor. Some also add an anti-sway device. Finally, the data passes The wireless device communicates to the server. This kind of fire extinguisher air...
