Description
Technical field
The utility model relates to a kind of communication device of digital visual safety cap for mine, the communication device of digital visual safety cap for mine that carries out visual rescue when having an accident especially for remote assistance personnel in the pit work and colliery.
Background technology
In mine rescue, assistance technology, visualization technique has improved its efficient, has increased the hope of life for the personnel of meeting with misfortune more, has also improved production efficiency.But in the prior art, mostly do not possess digitlization environment measuring and radio function on the one hand, be not easy to carry and use, function singleness, the signal transmission is difficult; The wireless communication platform of second aspect mine can't cover all tunnels, down-hole, and the blind area is more; This kind equipment of the third aspect relies on the wireless communication platform of mine mostly fully, when having an accident, communication cable and wireless communication platform can be destroyed, be difficult in short time repair, and there are many collieries that wireless telecommunications are not installed, make and to carry out signal instantaneous transmission such as video and environmental parameter under aboveground.
Summary of the invention
The purpose of this utility model is in order to overcome the above-mentioned shortcoming of existing synthesizer, a kind of communication device of digital visual safety cap for mine to be provided.
For achieving the above object, the technical solution of the utility model is that communication device of digital visual safety cap for mine 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.
Main body of the present utility model is a digital visual safety cap for mine, and has designed supporting communication device for it.The volume and weight of digital visual safety cap for mine is suitable with common safety cap, integrated audio frequency and video functions, environment measuring function, wireless transmission function.The digital safety cap 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 operational 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 make digital visual safety cap for mine guarantee to use in the wireless telecommunications blind area, also can not install or install the down-hole use that wireless telecommunications are destroyed by accident.The underground work personnel wear this digital visual safety cap for mine, have improved mine rescue speed and remote assistance efficient.
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 digital visual safety cap for mine, 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 analog signal with the form instant playback of numeral or curve on display screen.
Superiority of the present utility model is not only integrated audio frequency and video communication device and digitlization environmental detection set in safety cap, and to signal transmission having carried out multi-line design, digital visual safety cap for mine under any circumstance can be brought into play, make aboveground staff implement rescue and to assist commander the down-hole, and the digitlization environmental detection set in the cap has guaranteed staff's safety itself by wireless communication platform and network.
