Rate shut-off conducting, for infrared light-emitting diode LED also by corresponding frequency scintillation, the core board on charging rack receives certain frequency
Infrared signal, and then provide signal to wireless charging battery plate radiating circuit, if battery is full of, wireless charging battery plate does not work;Instead
It, the work of wireless charging battery plate.Charging management chip can detect current voltage, and to judge the state of battery, battery status is different,
The status signal that charging management chip is sent is just different, and the frequency of infrared light-emitting diode LED flickers is also just different, and core board is red
After outer receiving terminal receives signal, provide and the working condition of wireless charging battery plate is also differed.
Colliery is wired charging frame with charging rack at present, and the infrared control wireless charging module of present patent application is not yet in coal
Ore deposit uses, and compared with wired charging technology, infrared control wireless charging module has the beneficial effect that:
1. infrared light is utilized, into the transmission of row information, only mine lamp need to be placed between charging panel and mine lamp on charging panel
Charging can be completed, without being finally present with the micro connector of abrasion, without being inserted into charger.
2. point-to-point intelligent charge can monitor the mine lamp charging state of the charge position.
It is 3. intelligent.Even if charge position user changes, power interface can be also worked normally, it is necessary to when charging, transmitting terminal
Work can be automatically begun to simultaneously with receiving terminal, and when fully charged, two sides are just automatically closed.
4. security.In theory, this system is completely harmless to the people of local environment, because electricity is only with same
It is transmitted between the coil of frequency resonance, without exposed connector, the security risks such as electric leakage, leakage of electricity all thoroughly avoid.
