Step 5, after step 4, inserts waiting list by auxiliary charging case.Wherein, waiting list is the sequence that the auxiliary charging case swiped the card is queued up, and sortord can be sort successively according to the order swiped the card, and auxiliary charging case inserts the last position of current waiting list.
Step 6, after step 5, it is judged that whether charging watcher thread is hung up.Charging watcher thread is hung up and is illustrated to be connected with direct-current charging post currently without auxiliary charging case, if it is judged that charging watcher thread is not hung up, returns step 3.
Step 7, if it is judged that charging watcher thread is hung up, then wakes charging watcher thread up, performs closing relay.Closing relay is the relay closing the auxiliary charging case that current waiting list ranks the first, and the auxiliary charging case ranked the first to control current waiting list leads to direct-current charging post Electricity Federation.
Step 8, after closing relay, reads recharged card information.The information such as the residue electricity charge of reading recharged card.
Step 9, it is judged that whether charging completes, if be not fully complete, returns step 9.
Step 10, commands in step 9, if it is judged that charging complete, then disconnects the relay of the auxiliary charging case currently electrically connected with direct-current charging post.
Step 11, calculates the electricity charge.The amount of money according to the Time Calculation electricity charge that auxiliary charging case is powered, after calculating the electricity charge, it is possible to the information of recharged card is modified, rewrites the information of the residue electricity charge amount of money of recharged card.
Step 12, it is judged that whether depositor is empty.Depositor is the memorizer for storing waiting list, after the auxiliary charging case charged disconnects with direct-current charging post, will come deputy auxiliary charging case and be discharged to first, sequence below the like.If the auxiliary charging case in waiting list all charges complete, then depositor is empty.
Step 13, if it is judged that depositor is empty, then hangs up charging oracle listener.
Step 14, if it is judged that depositor is not empty, then continues executing with charging oracle listener, returns step 7.It should be noted that, can perform in the computer system of such as one group of computer executable instructions in the step shown in the flow chart of accompanying drawing, and, although illustrating logical order in flow charts, but in some cases, it is possible to perform shown or described step with the order being different from herein.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
