Existing smog, Smoke Sensor can drive electric automobile wireless charging monitor to alarm, the electric automobile wireless charging monitoring
Device will automatically cut off the power supply of wireless charging system, and relevant information is uploaded into monitoring by wifi transceivers simultaneously
Room, Control Room are sent relevant information on the user mobile phone using wireless charging again；
Further, the power interface power supply mode uses duplex feeding structure, all the way civil power, another way battery；
Because when running into alarm and taking emergency power off, commercial power interface can disconnect, and battery interface can power, and the system of the invention can
To work on, the benefit for continuing storage battery power supply is exactly, when fire occurs for charging vehicle periphery, the cut-off situation of civil power
Under, minisize pick-up head can continue to provide the picture of scene of fire to fire fighter by storage battery power supply, be advantageous to fire-fighting work
The development of work；
The operation principle design of the present invention is as follows：
First, when electric automobile carries out wireless charging, in vehicle by the position of transmitting coil and receiving coil to after good,
Minisize pick-up head below car, which can gather a width, does not have the picture of foreign matter, and will save as contrast picture；
Secondly, when vehicle user is left, the picture that gathers later can be carried out pair with that width contrast picture for retaining automatically
Than when monitoring contrast finds picture difference, detection temperature sensor and Smoke Sensor, if do not noted abnormalities, only passing through
Abnormal picture is uploaded to Control Room by wifi transceivers, and alarm is not alarmed, and relevant information is transmitted to the hand of car owner by Control Room
On machine, car owner can be monitored and be controlled by mobile phone remote；
Finally, when monitoring contrast finds picture difference, now detection temperature sensor and Smoke Sensor, if all existed
Abnormal parameters, then send at once and alarm and start breakpoint relay, directly cut off the power supply of whole wireless charging system, together
When relevant information uploaded into Control Room by wifi transceivers, and emergency notice short message is sent by the peripherad pedestrians of wifi,
Pedestrian or passerby is allowed to pay attention to detouring；
Beneficial effect：
1st, using the structure design of two minisize pick-up heads, between the discovery transmitting coil and receiving coil that can accurately understand
With the presence or absence of foreign matter, or charging station and charging vehicle are with the presence or absence of charging anomaly；
2nd, wireless charging system monitor be free to stretch, and not interfere with the charging operation of wireless charging system
Meanwhile also help that to allow monitored picture quality to obtain optimal；
3rd, two sets of electric power systems are employed, it is contemplated that two kinds of situations of disaster prevention and control；
4th, while carrying out picture algorithm process using minisize pick-up head, temperature sensor and smog sensing are additionally used
Device, the degree of accuracy of monitoring is allowed to improve.
5th, with reference to wifi transceivers, monitoring can be provided for pedestrian and Control Room first, simultaneously, moreover it is possible to be by Control Room
Vehicle user provides policer operation.
6th, it is not accurate enough for current foreign bodies detection, and metallic foreign body is very big on wireless charging influence, and national standard is put into effect
Foreign bodies detection this, and occur in charging electric vehicle battery overheat can set off an explosion, the discovery that the system can be clear
Foreign matter, and the battery exception of electric automobile and the exception of surrounding environment can also be found.
