Summary of the invention
In view of the foregoing, the purpose of this utility model provides a kind of can monitor in real time the charger in the charging process, battery condition, parameter, electric automobile charging station data switching networks system of adopting the DeviceNet bus to connect.
For achieving the above object, the utility model is taked following design: a kind of electric automobile charging station data switching networks system based on DeviceNet, and it is isolated bridger, accumulator monitoring system PC and 11～25V DC power supply by the battery management system on the electric automobile, battery management system data acquisition module, charger, charger supervisory control system PC, DeviceNet and constitutes; It is characterized in that: they link to each other by communication speed height, real-time row DeviceNet bus strong, that have dynamic connection and support hot swap characteristics each other.
In specific embodiment of the utility model, described battery management system data acquisition module is connected with a DeviceNet interface of battery management system by the DeviceNet bus; Another DeviceNet interface of battery management system links to each other with a DeviceNet interface on the charger by the DeviceNet bus; Another DeviceNet interface of charger links to each other with the DeviceNet interface of charger supervisory control system PC by the DeviceNet bus again, constitutes the network system of in the charging process charger state being monitored in real time;
Described battery management system data acquisition module is connected with a DeviceNet interface of battery management system by the DeviceNet bus, simultaneously, also link to each other with the DeviceNet interface that DeviceNet isolates bridger by the DeviceNet bus, another DeviceNet interface that DeviceNet isolates bridger links to each other with the DeviceNet interface of electric power storage monitoring system PC by the DeviceNet bus, constitute in the charging process to battery condition, greatly data on flows monitor in real time, the network system of data acquisition;
Whole network system is by 11～25V DC power supply.
The utlity model has following advantage:
1, system real time is strong.
Because the high several times of DeviceNet bus communication speed ratio RS-485 bus are to tens of times, can reach 500Kps, so, the charging station data switching networks system that adopts high speed DeviceNet bus to connect can realize the real-time control to charger, storage battery, has real-time distinguishing feature.
2, system configuration is simple, and antijamming capability is strong.
Because being connected with DeviceNet in data transmission link, the utility model isolates bridger, DeviceNet isolates the function that bridger has Network Isolation and communications protocol conversion, so the utility model antijamming capability is strong, and simplified the system interface design greatly, system configuration is simple.
3, adopt the DeviceNet network system of production/consumption mode with dynamic connection, the fieldbus networks system that constitutes with the RS-485 bus of master/slave pattern compares, simplified Interface design greatly, improve system bus efficient and management system PC CPU efficient, had very strong system real time.
4, adopt the dual bus frame design, promptly the system that links to each other by two DeviceNet buses monitors in real time and manages the state of charger, the state/data acquisition of storage battery respectively, satisfies the electric automobile charging station network system monitored, manages, reaches big flow data collector in real time to charger state, battery condition in the charging process purpose.
