In addition, the tri-state buffer gate chip U5 is skillfully arranged to receive the recharging host device information read by the USB interface P2 and send a recharging password to the incoming communication controller U3. When the tri-state buffer gate chip U5 is in a state of reading the information of the recharging host device, the recharging password transmitted by the microcontroller U1 is in a temporary storage state, and similarly, when the tri-state buffer gate chip U5 is in a state of issuing the recharging password, the information of the recharging host device is read and is in the temporary storage state.

first, the USB interface P2 is accessed to a recharging host device.
Secondly, when the wireless communication module U2 receives a recharging interruption signal issued by the LoRa base station, waiting to receive recharging information extraction data corresponding to the recharging interruption signal; otherwise, the remote recharging device keeps the dormant state consistently.
And thirdly, transmitting the recharging interruption signal and recharging information extraction data corresponding to the recharging interruption signal to the microcontroller U1 by utilizing the wireless communication module U2. If the recharging information extraction data corresponding to the recharging interruption signal is not received within 10-30 ms, returning to the second step, and continuing to wait for the recharging interruption signal. In this embodiment, the recharge information extraction data includes a recharge password and extract recharge host device information.

And fourthly, checking whether the format of the recharging information extraction data corresponding to the recharging interruption signal is correct, and if the format of the recharging information extraction data is wrong, returning to the second step to continue waiting for the recharging interruption signal. And if the format is correct, the recharging password is issued to the incoming communication controller U3 through the microcontroller U1 for recharging or the USB interface P2 is utilized to read recharging host equipment information and the recharging host equipment information is utilized to be transmitted to the LoRa base station through the wireless communication module U2. Here, the wireless communication module U2 may be used to send the recharging status of the recharging host device to the LoRa base station, and if the wireless communication module U2 does not receive the response fed back by the LoRa base station within 30s, the recharging status of the recharging host device is continuously sent to the LoRa base station until the recharging host device information and the recharging status are fed back to the LoRa base station.
