Early warning method of wireless gas detection and mine lamp thereof

Abstract

The invention discloses an early warning method of wireless gas detection and a mine lamp thereof and belongs to the coal mine safety equipment technology field. According to the early warning mine lamp of the wireless gas detection, a gas measurement circuit and a communication line of a ZigBee technology are installed in the mine lamp. The early warning mine lamp of the wireless gas detection comprises a LED indication, a sound alarm, the gas detection, a touch switch, power supply management, a LED illuminating lamp, power amplification and a Zigbee wireless radio frequency transceiver. The LED indication, the sound alarm, the gas detection, the touch switch, the power supply management, the LED illuminating lamp, the power amplification and the Zigbee wireless radio frequency transceiver are installed on the mine lamp. The LED indication, the gas detection and the sound alarm are connected with the Zigbee wireless radio frequency transceiver through an I/O interface. The touch switch and the power supply management are connected with the Zigbee wireless radio frequency transceiver. The power amplification is connected with a radio frequency transceiver module of the Zigbee wireless radio frequency transceiver. The LED illuminating lamp is connected with the power supply management. Through using the ZigBee technology, energy consumption of a product is less; the weight is light; a price is cheap and popularization is easy.

Description

Technical field [0001] The invention wireless gas test warning method and mining light involved a two -way communication and positioning with ZigBee technology. It has gas testing and accurate early warning capabilities and can be used for patrol device. It belongs to the technology field of coal mine safety equipment. Background technique [0002] The coal seam gas during the mining process of coal mines is one of the important factors affecting the safety of the mine.Gas concentration detection and risk early warning are important technical means to control gas accidents and realize the production safety of coal mines.The positioning of the personnel of the coal mine is very important for safety production.In the early days, the coal mine adopted a fixed coal mine gas measurement device, which required a large number of gas testing equipment, and the installation location was also limited. It was very inconvenient to install on the work surface.Use a mobile gas detector to dete...

Problems solved by technology

The design of this patent has made obvious progress, but there are still some shortcomings: first, the price of the multi-sensor fusion helmet proposed in the patent is a problem; second, the multi-function helmet consumes a lot of power and is inconvenient to use; Information, using RFID technology for identification, the superposition of the two technologies will make the cost relatively high

[0010] Considering the use of fixed gas measuring equipment to detect gas in coal mine roadways, there are problems of insufficient equipment quantity and inconvenient installation; using mobile gas detection equipment requires a special person to be responsible, and real-time detection cannot be completed manually; using general gas early warning helmets to detect gas concentration, Due to the lack of location information, there is a problem of false alarms; gas helmets are also very difficult due to the large number of calibrations; with general wireless solutions, the harsh environment in coal mines and the cost of promotion need to be considered
