Abstract
The utility model relates to a wireless monitoring device for mining, which comprises a video camera, a headphone, an audio-compression and video-compression module, an air sensor, a temperature sensor, a DAC (digital analogue converter), a carrier demodulator module and a wireless transmission module. The wireless monitoring device for mining can transmit living audio, living video and living environmental data to the ground instantly. The wireless monitoring device can transmit images clearly and stably, has no smear, can realize a voice call while wireless video is being performed. A free call through an explosion-proof mobile phone can be realized in the system, monitoring data can be transmitted in the system, and the system is efficient and stable. Workers on ground can perform a rescue and an assistant command to workers underground through a wireless communication platform and a wireless communication network.
Description
Technical field
The utility model relates to a kind of mine wireless monitor supervising device, belongs to mine downhole monitoring field.
Background technology
Modern coal mines is paid much attention to safety in production, and traditional monitoring video system can not be accomplished the real-time monitoring of optional position owing to be subjected to the limitation of wire transmission pattern to the safety in production hidden danger in colliery.Because the image frame of passing back is dismal unintelligible, mobile streaking is serious, and the security control personnel can't screen interpretation to image content, so the technician can not make correct assessment to accident potential.Traditional wired monitoring video equipment is bulky, and power consumption is big, and weight is big, can't carry; And function singleness can only images, can not form a comprehensive monitoring and controlling system.
Summary of the invention
The purpose of this utility model is in order to overcome the above-mentioned shortcoming of existing monitoring and controlling system, a kind of mining wireless monitor supervising device to be provided.
For achieving the above object, the technical solution of the utility model is that mining wireless monitor supervising device comprises video camera, headset, audio frequency and video compression module, gas sensor, temperature sensor, digital-to-analogue DAC, carrier modulation module and wireless transmitter module.
The utility model is integrated audio frequency and video functions, environment measuring function, wireless transmission function.Can by its supporting communication device with audio frequency and video, the environmental data at scene instant be transferred to ground.The audio frequency and video function makes aboveground staff can get information about the down-hole sight, to make more rational commander and assistance; The environment measuring function can testing personnel site gas density, oxygen content, temperature information, with the safety that guarantees working environment with make timely analysis and decision-making; Wireless transmission function is transmitted to wireless communication base station with above data with radio magnetic wave.Communication device can guarantee to use in the wireless telecommunications blind area, also can improve mine rescue speed and remote assistance efficient not installing or installed the down-hole use that wireless telecommunications are destroyed by accident.
Integrated photoelectrical coupler (miniature CCD video camera), headset, gas sensor, temperature sensor, audio frequency and video compression module, digital-to-analogue DAC, carrier modulation module, wireless transmitter module devices such as (RF) in the mining wireless monitor supervising device, the staff under mine during operation camera with people's sight line shooting, headset and aboveground dispatcher carry out duplex voice conversation, the environmental information around each sensor acquisition.Video data and double-directional speech data are modulated on the predefined frequency range by the carrier modulation module after by audio frequency and video compression module boil down to Media Stream, the gas density that gas sensor is gathered, oxygen content, the temperature information data are converted to digital signal by digital-to-analogue DAC with analog data and are modulated on the predefined frequency range by the carrier modulation module, these data are transmitted into surrounding space by the form that wireless transmitter module amplifies with radio magnetic wave simultaneously, wireless telecommunication system receives signal automatically and is transferred to aboveground, processing by switching equipment and server, audiovideo behind the decompress(ion) is play immediately at multimedia microcomputer, digitized environmental information data be reduced to simulating signal with the form instant playback of numeral or curve on display screen.
Advantage of the present utility model is: the common fault that overcomes wired monitoring under the existing well, steady and audible, the no conditions of streaking of transmission picture, energy voice call when realizing wireless video, the realization antiexplosion telephone is freely conversed at native system, realize the transmission of monitoring data at native system, system high efficiency is stable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, video camera, 2, headset, 3, the audio frequency and video compression module, 4, gas sensor, 5, temperature sensor, 6, digital-to-analogue DAC, 7, the carrier modulation module, 8, wireless transmitter module.
Embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
Embodiment as shown in Figure 1, mining wireless monitor supervising device be configured to video camera 1, headset 2, audio frequency and video compression module 3, gas sensor 4, temperature sensor 5, digital-to-analogue DAC6, carrier modulation module 7 and wireless transmitter module 8.To be video camera 1 and microphone 2 be modulated to audio-video signal on the predefined frequency range by carrier modulation module 7 after by audio frequency and video compression module 3 boil down to Media Streams its principle of work, gas sensor 4 and temperature sensor 5 are digital signal by digital-to-analogue DAC6 with analog signal conversion, also be modulated on the predefined frequency range by the carrier modulation module, these data transmit upward well by the form that wireless transmitter module amplifies with radio magnetic wave simultaneously, signal is transferred to aboveground back software and services device system with the audio-video signal decompress(ion), on multimedia microcomputer, play immediately, digitizing environmental information data be reduced to simulating signal with the form instant playback of numeral or curve on display screen.
