Referring to fig. 1 to 3, a low power consumption operation terminal of a charging pile includes the steps of:
S1, a charging main control board detects the communication condition of each module in the charging pile in real time, when communication abnormality occurs, the charging pile is controlled to enter a low-power consumption mode, and otherwise, the step S2 is executed;

Each module in the charging pile comprises an IO detection module, a lamp strip control module, a camera control module, an insulation detection module and a direct current ammeter.
As can be seen from the above description, the charging pile is an integral working system, and when communication of a certain module in the charging pile system is abnormal, the charging pile is not available, so that the charging pile needs to be powered off to stop charging work; meanwhile, the communication connection between each module in the charging pile and the charging main control board is disconnected, and only communication connection with abnormal communication is reserved, so that the charging pile can be quickly started to recover normal charging work when the modules with abnormal subsequent communication recover normal communication while low energy consumption is ensured.
Further, the step S2 specifically includes:

s44, if (t1+t5) is greater than (t2+t4), t3=t1+t5, otherwise t3=t2+t5.

S1, a charging main control board detects the communication condition of each module in the charging pile in real time, when communication abnormality occurs, the charging pile is controlled to enter a low-power consumption mode, and otherwise, the step S2 is executed;
s2, detecting whether a gun inserting signal of the charging gun changes or not by the charging main control board at intervals of preset time, and if not, controlling the charging pile to enter a sleep mode;

S42, calculating the actual dormancy failure rate K' = (C1-C2)/C1 of the current day.
S43, if the actual sleep failure rate K' of the current day is greater than K, the situation that the current day has a short charging time interval, which results in sleep failure, is indicated, in order to reduce the sleep failure rate and improve the experience of the vehicle owner, the preset time of the next day needs to be increased, that is, step S44 is entered, otherwise, the preset time of the current day of the charging pile system is set reasonably and even with allowance, so that the preset time of the next day is reduced, that is, T3=T1-T5.
S44, if (t1+t5) is greater than (t2+t4), t3=t1+t5, otherwise t3=t2+t5.
The longest time interval T2, the preset sleep time length T4, the preset sleep improvement stepping time length T5 and the preset sleep failure rate K for the current sleep failure can be set according to the needs of different charging piles of different stations, and the preset sleep time length is a fixed value and can be obtained through actual testing.
