Step 4.1 Surveillance center 1 reads customer consumption record data, and customer consumption record data are stored to memory device 3, and judges whether customer consumption record data successfully deposit memory device 3 in, if, jump to step 4.2, if not, jump to step 4.1.1.
Step 4.1.1 Surveillance center 1 is stored in customer consumption record data in its memory cache.
Step 4.1.2 Surveillance center 1 judges that whether its memory cache is full, if so, jumps to step 4.1.3, and if not, data are kept in the memory cache of Surveillance center 1, and jump to step 4.2.
The oldest record data in its memory cache are deleted by step 4.1.3 Surveillance center 1, write and retain new customer consumption record data, and jumping to step 4.2.
Step 4.2 Surveillance center 1 judges in its memory cache, whether to need the customer consumption record data preserved, if so, jumps to step 4.3, if not, jumps to step 4.4.
Step 4.3 Surveillance center 1 is stored to the customer consumption record data in memory cache in memory device 3, and deletes data in memory cache.
The storage of step 4.4 Surveillance center 1 completing user consumer record data.
Step 5 Surveillance center 1 processes customer consumption record data.Electric automobile 4 is charged, if charging set 2 is found the transaction of last time and is not settled accounts, charging set 2 can have been asked to Surveillance center 1 the customer consumption record of clearing, and Surveillance center 1 will send to this consumer record charging set 2, to carry out settlement operations.
Step 6 Surveillance center 1 reads electric automobile 4 battery informations.
Step 7 Surveillance center 1 reads charging set 2 charge volume data.
Charging set 2 receives the ammeter data of ammeter on its 8 plugs in real time, and is sent to Surveillance center 1 by equipment state, and Surveillance center 1 reads the ammeter data of charging set 2.Complete and read and jump to step 1.
Above-mentioned ammeter data comprises: the rate 1 of plug one to eight rate 2 of ammeter data, plug one to eight ammeter data that charges that charges.A corresponding time-sharing ammeter of plug, has two readings (rate 1 reading, rate 2 readings) on every time-sharing ammeter.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.Read after foregoing those skilled in the art, for multiple amendment of the present invention and substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
