AT89C51 chip is also connected respectively with timer, electric automobile identification equipment and infrared ray sensing array, when receiving automobile by signal, automobile quantity is from adding 1, when receive automobile by signal and receive be absent from electric automobile signal time, on-electric automobile quantity is from adding 1, electric automobile quantity is that automobile quantity deducts on-electric automobile quantity, automobile quantity, electric automobile quantity and on-electric automobile quantity automatic clear weekly；
Wherein, charging socket is connected with measuring equipment, and for holding the charging plug of electric automobile, the battery for electric automobile is charged, measuring equipment is connected with alternating-current bidirectional controllable silicon, for detecting the electricity number being charged through the battery that charging socket is electric automobile；
Black and white threshold value value is between 0-255；
AT89C51 chip is positioned at the rack of charging pile agent structure.
