Technical field
The present invention relates to the fields such as electromagnetic field technology, information technology, and in particular to a kind of underground based on magnetic coupling resonance
Miner's rescue method is set with miner's clothes.
Background technique
When mine accident or mine disaster occur, the search and rescue to miner are that one important and difficult task.Existing search and rescue are set
It is standby mainly to have the detection device over the ground such as Ground Penetrating Radar and life-detection instrument, it is mainly made, is led to using the principle of reflection of electromagnetic wave
The analysis processing to reflection echo is crossed, is positioned to target is searched and rescued.But this search and rescue equipment by stratum media to signal
Interference effect is big, and these equipment need complicated signal processing algorithm and high performance processing hardware, and equipment composition is accurate, profession
Property is strong, and cost is also higher.Furthermore these rescue methods can only help rescue worker to understand and be rescued the situation of miner, and well
Under stranded miner can not but receive corresponding feedback information, such as: stranded miner is difficult know whether rescue worker reaches, quilt
Whether tired miner oneself has been found and information of the rescue worker apart from oneself distance etc. by rescue worker.Although these information
Simply, it is positive stimulus but for stranded miner, positive shadow can be brought to the chances of survival under its hard situation
It rings.
Magnetic coupling harmonic technology is initially a kind of wireless energy transmission technology, the basic principle of the technology are as follows: transmitting terminal sense
It answers coil to be passed through alternating current, generates the induced magnetic field of frequency of oscillation, when the intrinsic frequency of reception device is identical as frequency of oscillation

Show, then determine that the direction has miner, should indicate that rescue worker searches in the direction；If transmitting terminal is when front direction is without obvious
Feedback current variation, then after adjustment direction, continue to complete the scanning to area of space by step 2 and 3.
In above-mentioned rescue method, when the coil in the miner's clothes and miners' cap that end and underground are searched and rescued in ground reach couple it is humorous
After vibration, LED light and/or buzzer are triggered, informs that miner searches and rescues end discovery by ground, miner also can be according to the brightness of LED light
Or the intensity of sound of buzzer judges the distance of rescue worker's distance.
The present invention is according to magnetic coupling harmonic technology principle, and transmitting terminal generates the induction field of specific frequency of oscillation, when received
When the intrinsic frequency of induction coil is identical as frequency of oscillation, receiving end can generate strongest induced current, so that magnetic energy be converted
For electric energy.Meanwhile after reaching coupled resonance, for transmitting terminal, being equivalent to realizes load matched, to emit terminal circuit
Electric current can generate variation, and energy is to load transmission.Therefore, by monitoring the variation of transmitting terminal electric current, it is known that whether
There are receiving end and transmitting terminal to reach coupled resonance state.In addition, itself carries directional information since magnetic field is vector field,
When receiving end induction coil face emits induction coil, induced current is maximum.According to principles above, the present invention considers on ground
One electromagnetic launch system of upper placement, in underground, miner is equipped with the miner's clothes for being built-in with specific intrinsic frequency induction coil and miner
Cap, in this way, transmitting terminal, if there is the variation of feedback current, can judge this when a direction emits alternating electromagnetic field
The progress searched and rescued is instructed whether with the presence of miner in direction.
Compared with prior art, the present invention has the following advantages that and technical effect:
(1) it is not necessarily to sophisticated signal Processing Algorithm, using magnetic coupling resonance as basic principle, soft and hardware is constituted simply the present invention,
Signal processing algorithm and high performance computation module without conventional radar survey meter complexity.
