Wherein, Said Zigbee terminal module is in order to the data message of gathering discrete charging pile and send to the Zigbee main control module; The discrete charging pile data message that said Zigbee main control module will receive sends to station level Surveillance center; A said station grade Surveillance center handles and stores the discrete charging pile data message that receives, and is uploaded to upper level Surveillance center.
Further, said Zigbee network also comprises several Zigbee routing modules, and said Zigbee routing module is connected with the Zigbee main control module with the Zigbee terminal module respectively.
Preferably, a said station grade Surveillance center comprises supervisory control comuter, database server and warning device, and said database server is connected with supervisory control comuter respectively with warning device.
Preferably, said Zigbee main control module comprises Zigbee telegon, power module and Anneta module, and said Zigbee telegon is connected with Anneta module with power module respectively.
Preferably, said Zigbee terminal module comprises power module, Zigbee acquisition module and Anneta module, and said Zigbee acquisition module is connected with Anneta module with power module respectively.
Preferably, said Zigbee routing module comprises power module, Zigbee route and Anneta module, and said Zigbee road is connected with Anneta module with power module respectively.
Preferably, said Zigbee main control module is connected with supervisory control comuter through standard serial ports such as RS232 and RS485.
Preferably, said Zigbee terminal module is connected with discrete charging pile through standard serial ports such as RS232 and RS485.
The invention has the beneficial effects as follows: the present invention not only utilizes Zigbee network quickly networking; The information transmission such as voltage, electric current, metering and billing of automatically electric automobile being filled discrete charging pile in the electrical changing station are to server; Satisfy the needs that discrete charging pile datamation is gathered; And greatly reduce the mobile communication expense, and having reduced electric automobile charging pile and the operation cost of filling electrical changing station, the operation of electric automobile being filled electrical changing station provides important safety guarantee.

Below in conjunction with accompanying drawing the present invention is described further:
Fig. 1 theory diagram of the present invention;
The theory diagram of Fig. 2 station according to the invention level Surveillance center.
Among the figure, 1 station level Surveillance center, 11 supervisory control comuters, 12 database servers, 13 warning devices, 2Zigbee main control module, 3Zigbee routing module, 4Zigbee terminal module, 5 discrete charging piles.
Embodiment
As illustrated in figs. 1 and 2, a kind of electric automobile of the present invention charging pile data acquisition system (DAS) that disperses comprises station level Surveillance center 1 and through connected several the discrete charging piles 5 of Zigbee network.A said station grade Surveillance center 1 comprises supervisory control comuter 11, database server 12 and warning device 13, and said database server 12 is connected with supervisory control comuter 11 respectively with warning device 13; Said Zigbee network comprise several Zigbee main control modules 2, as do a Zigbee routing module 3 and with discrete charging pile Zigbee terminal module 4 one to one; Said Zigbee terminal module 4 is connected with discrete charging pile 1 through standard serial ports such as RS232 and RS485; And through Zigbee routing module 3 or directly be connected with Zigbee main control module 2; Said Zigbee main control module 2 is connected with the supervisory control comuter 11 of grade Surveillance center 1 of standing through standard serial ports such as RS232 and RS485, and said Zigbee routing module 3 is transmitted to Zigbee main control module 2 in order to the image data information with Zigbee terminal module 4; Wherein, said Zigbee main control module comprises Zigbee telegon, power module and Anneta module, and said Zigbee telegon is connected with Anneta module with power module respectively; Said Zigbee routing module comprises power module, Zigbee route and Anneta module, and said Zigbee road is connected with Anneta module with power module respectively; Said Zigbee terminal module comprises power module, Zigbee acquisition module and Anneta module, and said Zigbee acquisition module is connected with Anneta module with power module respectively.
The course of work of the discrete charging pile data acquisition system (DAS) of this kind electric automobile is following:
Said Zigbee terminal module 4 is connected with discrete charging pile 5 through RS232 or RS485 standard serial port and gathers data messages such as its voltage, electric current and metering and billing; Zigbee main control module 2 is transmitted or directly sent to Zigbee terminal module 4 with the data message that collects through Zigbee routing module 3; The discrete charging pile related data information that said Zigbee main control module 2 will receive sends to the supervisory control comuter 11 of station level Surveillance center 1; The data messages such as discrete charging pile voltage, electric current and metering and billing that 11 pairs of said supervisory control comuters receive are handled and the information such as numbering, charging voltage, charging current and charging expense of the charging pile that will disperse send to database server 12 storages so that retrieval fast is uploaded to upper level Surveillance center with related data information simultaneously; When discrete charging pile data exceed setting value, supervisory control comuter 11 will send warning message and give warning device 13 in order to report to the police.
Native system not only utilizes Zigbee network quickly networking, and information transmission such as the charging pile charging of will dispersing automatically satisfy the needs that the charging pile datamation is gathered to server; And can reduce the mobile communication expense greatly, and reducing electric automobile charging pile and the operation cost of filling electrical changing station, the operation of also electric automobile being filled electrical changing station simultaneously provides important safety guarantee.
Invention has been described though above-mentioned embodiment combines accompanying drawing; But be not restriction to protection domain of the present invention; One of ordinary skill in the art should be understood that; On the basis of technical scheme of the present invention, those skilled in the art need not pay various modifications that creative work can make or distortion still in protection scope of the present invention.
