S102, obtaining a starting ammeter reading and an order starting time when charging is started;
s103, updating the thermal data structure according to the initial electric meter reading and the order starting time, and writing the updated data structure into the FRAM;

s701, receiving a thermal data structure;
s702, judging the legality of the thermal data structure by calculating the charging amount of each time period;
specifically, when the validity of the thermal data structure is judged, a normal range of the electric quantity deducted per hour can be obtained by analyzing the previous charging data, and thus, when the electric quantity deducted per hour exceeds the normal range, the order abnormality can be judged.
S703, if the thermal data structure is illegal, sending a charging failure instruction;
s704, if the hot data structure is legal, whether the hot data structure is tampered or not is verified through cyclic redundancy;

S705, if the hot data structure body is tampered, a charging failure instruction is sent out;
s706, if the hot data structure body is not tampered, deducting money of a user;
and S707, sending a charging completion instruction after the deduction is completed.
And after receiving the hot data structure body at the receiving end, the server verifies the legality and whether the hot data structure body is tampered, and deducts money from the user after the verification is passed, so that the charging is finished to prepare for receiving a charging request of the next client.
In addition, after the server receives the thermal data structure, the state of the current order can be acquired through the order state information stored in the check mark position, so that whether the current order is the order in the normal state or the reset order after the charging pile is restarted after power failure can be judged.
