Explosion-proof handheld mobile communication terminal for mine

This invention discloses an explosion-proof handheld mobile communication terminal for a mine. The mobile communication terminal comprises an all-Netcom CPU (Central Processing Unit) module (1), a gravity sensor module (2), a light sensor module (3), a temperature senor module (4), an air pressure sensor module (5), a magnetic force sensor module (6), a gyroscope module (7), an infrared radiation detection module (8), an infrared remote control module (9), a Big Dipper positioning radio frequency module (10), a GPS (Global Position System) radio frequency module (11), a NFC (Near Field Communication) radio frequency module (12), a ZigBee module (13), a Bluetooth module (14), a WIFI (Wireless Fidelity) module, a hardware talkback module (16), an SOS emergency call module (17) and a one-key alarm module (18). The mobile communication terminal provided by the invention is suitable for various wireless communication systems built under the mine, and realizes functions of voice communication, talkback, wireless data acquisition, infrared remote control, equipment NFC label scanning, staff and moving target positioning, high-temperature detection of equipment, one-key alarm and the like. The problem that different communication systems use different mining mobile phones can be avoided; and thus, the communication efficiency and economic benefits can be further improved.
