Wherein the third cycle is greater than the second cycle, and the second cycle is greater than the first cycle, sets up the cycle alone between individual charging pile encapsulation and the crowd charging pile encapsulation and decoding, can avoid long-range backstage to need wait for the condition that data synchronization just can handle data in same cycle after three cycle setting is unanimous to take place, prevents that three cycle setting from giving up not synchronous data because of data is asynchronous after being unanimous, improves the utilization ratio of data.
As shown in fig. 2, step S3 further includes step S31 and step S32. Step S31: after activation, the remote back-office saves the external information it receives and internal change information that changes internally in response to the external information. Step S32: and finding out and deleting the internal change information which is the same as the external information, and releasing the memory. The method and the device realize the historical data recording function, can check the duplicate and delete the repeated information, and improve the utilization rate of the file storage space.
Step S4: and issuing the activated coping processing order to the maintenance terminal. The activated coping process orders are sent individually one-to-one. When charging pile breaks down, can send reply handling order promptly fault information to the maintenance unit, the maintenance unit can be through long-range backstage promptly the thing networking platform directly distribute the order to the maintenance terminal promptly and hold the maintenance personnel who removes the end promptly, avoids charging pile long-time unable use.
As shown in fig. 3, step S4 further includes:
step S41: and sending the activated coping processing orders to a plurality of maintenance terminals in a group mode. And sending the messages to a plurality of maintenance terminals in a group by the remote background.
Step S42: and acquiring the position of a maintenance terminal which actively receives the coping processing order. And the remote background reads the GPS positioning coordinate of the maintenance terminal.
Step S43: and calculating the position closest to the position, and selecting the maintenance terminal corresponding to the position to finally correspond to the activated coping processing order. And corresponding the activated coping processing order to the nearest maintenance terminal.
Step S44: and sequencing the historical final corresponding times of all the maintenance terminals actively receiving the coping processing orders, and carrying out rest suspension with set time on the maintenance terminal with the highest time.
The nearest maintenance terminal of the electric pile that fills who breaks down is dispatched to the maintenance before, can also avoid single maintenance terminal to brush the list many times in the short time, prevents simultaneously that the people from deliberately shortening maintenance time, avoids reducing maintenance quality.
Step S5: and recording the historical failure times of the single charging pile.
Step S6: and if the historical fault times are larger than the preset fault value, the remote background marks the charging pile and sends the mark symbols to all maintenance terminals. And after the maintenance terminal passes through and maintains the charging pile with the mark symbol, the maintenance terminal eliminates the mark symbol and informs a remote background to eliminate the mark symbol corresponding to the charging pile.
Carry out the group control to filling electric pile, realize alone the remote management to a plurality of electric piles that fill. Big data analysis is carried out to historical data, realizes the product trouble early warning, and statistics fills the frequent fault point of electric pile, does benefit to the later stage and optimizes the promotion and provides help to filling electric pile product upgrading. And the mark symbol is removed periodically, so that the display interface is clearer, and the patrol of the working personnel on the interface of the remote background is facilitated.
