• the rescued vehicle APP automatically starts the user module;
• the user module is connected to the access module of the rescue platform with a 3G/4G network through the communication module and internet;
• and the driver enters a main page of the rescued vehicle APP after passing the authentication of the rescue platform and the user authentication module;
• at this time, the driver uses the one-key rescue function, and the order module is immediately started to send rescue application information, user data and current GPS position data of the user to the rescue platform through the communication module and internet, and the access module of the rescue platform acquires the data and immediately pushes such data to the order execution module;
• 3) A complete order form is generated in the order execution module, and meanwhile, the acquired user information is matched with vehicle data in a database by virtue of the order form;
• and the vehicle data and the GPS data are packaged and pushed to the vehicle selection module;
• 4) the vehicle selection module acquires a vehicle optimization application from the order execution module, then acquires related GPS data, idle state data and vehicle type matching data from the monitoring module of the rescue vehicle APP according to the GPS information of the rescued data and the vehicle data, and synthesizes the data;
• and each rescue vehicle is subjected to optimizing degree grading according to an optimal strategy algorithm, and the data is pushed to the order execution module according to a descending order of grades;
• 5) the operating personnel of the rescue platform select the most suitable vehicle according to the optimizing degree grades, and allocate the order to the rescue vehicle;
• 6) the rescue vehicle APP is installed on a display terminal of the rescue vehicle, and when the rescue vehicle works, the display terminal is started, and the rescue vehicle APP is connected to the rescue platform through the communication module and internet, and is authenticated by the user authentication module on the rescue platform;
• a monitoring module is provided in the rescue vehicle APP, and is in communication with a controller of the charging rescue vehicle through Bluetooth, the serial port, WIFI or Ethernet, and the controller of the charging rescue vehicle is connected to the direct current battery charger, the alternating current battery charger, the measuring module and the GPS device through the serial port;
• the monitoring module of the rescue vehicle APP acquires related data on a current, a voltage and a temperature of the direct current battery charger and the alternating current battery charger from the controller of the charging rescue vehicle;
• related data on electric quantity and a charging time of the measuring module and the GPS position data of the charging rescue vehicle are packaged and sent to the access module of the rescue platform through the communication module and internet, and the access module sends the data to the monitoring module of the rescue vehicle APP;
• and the monitoring module of the rescue vehicle APP monitors a position of each rescue vehicle, an alternating current, states of the direct current and alternating current battery chargers and measuring module data;
• 7) when the order data is sent to the rescue vehicle APP by the order execution module of the rescue platform through the communication module and internet, the order module in the rescue vehicle APP acquires order information and displays the order information to the rescue vehicle driver, and a rescue vehicle worker selects to accept or refuse according to his situation;
• the rescue platform reselects the rescue vehicle in case of selecting to refuse;
• the rescue platform calculates a distance and an expected rescue expense according to GPS of both the rescue vehicle and the rescued vehicle in case of selecting to accept;
• the rescue platform sends the expected expense, an expected arrival time and the relevant information of the charging rescue vehicle to the rescued vehicle APP;
• the rescued vehicle APP receives the information;
• the all-electric vehicle driver reviews whether to accept an order content;
• the order takes effect when the all-electric vehicle driver selects to accept the order;
• the order execution module of the rescue platform tracks an order execution process;
• and the order execution module acquires rescue vehicle data in the monitoring module of the rescue vehicle APP and shares the rescue vehicle data to the order module of the rescued vehicle APP through the communication module and internet;
• and the all-electric vehicle driver may inquire a position, a speed and an expected arrival time state of the rescued vehicle in the order module in real time;
