a2) when the charging is detected to be completed, the singlechip main control module 103 starts timing to prepare power-off, and when the timing time is up, the channel is immediately shut off;
a3) when the charger is plugged in and out in the normal charging process, the singlechip main control module 103 starts to time, and when the maintaining time of the continuous power-off condition reaches the set time, the channel is immediately cut off;
a4) after the channel is opened, if the charging equipment is not connected all the time, and the maintaining time of the situation reaches the set time, the channel is immediately closed, and the charging is not carried out. Under the above four conditions, after the power failure is executed, the data packet is immediately uploaded to the network cloud server 2, so that the APP/WEB side can timely push the channel power failure information service.
And a sixth step: charging cabinet device 1 power main road is gone into in series to arc extinguishing formula electric fire protection module 101, it detects cutting technology and trouble electric arc detection technique to have its distinctive arc extinguishing formula short circuit, when the dangerous spark that charging circuit takes place to charge short circuit or other trouble and lead to, arc extinguishing formula electric fire protection module 1 can in time cut off the charging circuit power, only break off dangerous fault point, but its self and 1 main control part of charging cabinet device still keep normal operating, with the most sensitive mode dash the emergence of stopping conflagration hidden danger in the root, guarantee charging safety, and upload alarm information to network cloud server 3 immediately, with APP/WEB end in time propelling movement short circuit alarm information that charges, in time get rid of hidden danger, guarantee the normal operating of charging.
The seventh step: the charging cabinet device 1 detects the information of the voltage, the current, the leakage current, the power, the frequency, the electric energy and the temperature of a main circuit in real time, and the charging loop detects the data of the current and the temperature and the state information. When the situations of undervoltage or overvoltage alarm of the main line voltage, overload of the main line current, alarm of the main line leakage current, alarm of the main line temperature and connection fault and alarm of the charging loop temperature are detected, the charging cabinet device 1 automatically ends the active data uploading mode of the original timing period, immediately uploads a data packet, starts a timing quick uploading function of a certain maintenance period according to different alarm types, and restores the active data uploading mode of the original timing period when the quick uploading period reaches or the alarm in the period is removed.
Eighth step: the charging cabinet device 1 receives control instruction information from an APP (application) end and a WEB (world Wide Web) end of a mobile phone in real time, the control instruction comprises basic operation instructions such as charging bin door opening, storage, charging and taking-out, resetting, self-checking and the like, and important parameter instructions are remotely read and written, each instruction has a response mechanism, a communication failure retransmission mechanism is arranged, and the reliability of GPRS (general packet radio service) wireless communication transmission is guaranteed to the maximum extent.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
