further, the three temperature sensors are respectively arranged at the center position of the transmitting coil, the front lower position of the transmitting coil and the rear lower position of the transmitting coil and are used for monitoring whether temperature abnormality occurs;
as an illustration, a smoke sensor is additionally arranged on the wireless charging monitor of the electric automobile, if smoke appears, the smoke sensor can drive the wireless charging monitor of the electric automobile to alarm, the wireless charging monitor of the electric automobile automatically cuts off the power supply of the wireless charging system and simultaneously uploads relevant information to a monitoring room through a wifi transceiver, and the monitoring room sends the relevant information to a mobile phone of a user using wireless charging;
furthermore, the power supply mode of the power supply interface adopts a two-path power supply structure, one path of commercial power and the other path of storage battery; because the utility power interface is disconnected and the storage battery interface is powered off when an alarm is met and emergency power failure is adopted, the system can continue to work, and the continuous power supply of the storage battery has the advantages that when the periphery of the charging vehicle is in fire disaster, the miniature camera can continuously provide a scene of the fire disaster for firefighters through the power supply of the storage battery under the condition that the utility power is disconnected, so that the development of the fire fighting work is facilitated;
the working principle of the invention is designed as follows:
firstly, when an electric automobile is wirelessly charged, after the positions of a transmitting coil and a receiving coil are aligned, a miniature camera below the automobile can acquire a picture without foreign matters and store the picture as a comparison picture;
secondly, when a vehicle user leaves, the later acquired picture is automatically compared with the reserved comparison picture, when the monitoring comparison finds that pictures are different, a temperature sensor and a smoke sensor are detected, if no abnormality is found, the abnormal picture is uploaded to a monitoring room only through a wifi transceiver, an alarm does not alarm, the monitoring room forwards relevant information to a mobile phone of a vehicle owner, and the vehicle owner can remotely monitor and control through the mobile phone;
finally, when monitoring and comparing to find that pictures are different, detecting the temperature sensor and the smoke sensor at the moment, if parameters are abnormal, immediately giving an alarm and starting a breakpoint relay, directly cutting off the power supply of the whole wireless charging system, uploading related information to a monitoring room through a wifi transceiver, and sending an emergency notification short message to surrounding pedestrians through wifi, so that the pedestrians or passers-by pay attention to detouring;
the beneficial effects are that:
1. by adopting the structural design of the two miniature cameras, whether foreign matters exist between the transmitting coil and the receiving coil or whether the charging station and the charging vehicle have abnormal charging phenomenon can be accurately and clearly found;
2. the wireless charging system monitor can be freely stretched and contracted, so that the charging operation of the wireless charging system is not influenced, and the quality of a monitoring picture is optimized;
3. two sets of power supply systems are adopted, and two conditions of disaster prevention and relief are considered;
4. the miniature camera is adopted to process the picture algorithm, and meanwhile, the temperature sensor and the smoke sensor are also adopted, so that the monitoring accuracy is improved.
5. By combining the wifi transceiver, monitoring can be provided for pedestrians and monitoring rooms at first, and meanwhile, monitoring operation can be provided for vehicle users through the monitoring rooms.
6. The system can clearly find the foreign matters, and can also find the battery abnormality of the electric automobile and the abnormality of the surrounding environment.
