20 communications.
Step S5, the master control borad 10 is logical with the multiple BMS 20 by the CAN network and the RS485 networks
News.
Whether step S6, the BMS 20 detect itself break down.When itself breaks down, step S7 is performed.
Step S7, the BMS 20 detect whether the CAN 50 breaks down.When the CAN 50 does not go out
During existing failure, step S8 is performed；When the CAN 50 breaks down, step S9 is performed.
Failure code directional broadcasting is given the master control borad 10 by step S8, the BMS 20 by the CAN network.
The failure code is transferred to the master control borad 10 by step S9, the BMS 20 by the RS485 networks.
In the present embodiment, it is described when the RS485 buses 30 and the CAN 50 do not break down
RS485 Network Priorities are used to transmit routine data, and the CAN network is preferentially used for transmission abnormality data, such as failure code.By
In the polling mechanism that the RS485 networks are accessed using principal and subordinate, only when the master control borad 10 sends inquiry instruction to the BMS
When, the BMS can just return to corresponding data, therefore, will not be similar to the CAN network causes data jamming because of broadcast data
Or the problems such as leakage frame, so as to be more suitable for transmitting routine data.However, in the RS485 networks, if a certain BMS failures, described
Failure code can not be transferred to the master control borad 10 by BMS immediately, but must wait until that the master control borad 10 is sent out again next time
Send inquiry instruction to the BMS, failure code could be transferred to the master control borad 10 by the BMS, so that the BMS failures
Operating lag.Therefore, in the present embodiment, abnormal data is preferentially transmitted with the broadcast mode of the CAN network, can be with
It is effectively prevented from the operating lag of the BMS failures.It follows that present embodiment makes full use of the RS485 networks and institute
The advantage of CAN network is stated, so that the reliability of the energy-accumulating power station 100 is stronger.
The present invention by setting the CAN network and the RS485 networks in the energy-accumulating power station 100 so that described
When CAN 50 breaks down, the master control borad 10 remains to be led to the multiple BMS 20 by the RS485 networks
News, so that the energy-accumulating power station 100 remains to normal work.In addition, equal in the RS485 buses 30 and the CAN 50
During without breaking down, the RS485 Network Priorities are used to transmit routine data, and the CAN network is preferentially used for transmission abnormality
Data, so as to make full use of the advantage of the RS485 networks and the CAN network, and then make the reliability of the energy-accumulating power station 100
Property is stronger.
The present invention is not restricted to described in description and embodiments, therefore can for the personnel of familiar field
Additional advantage and modification are easily realized, therefore in the spirit of the universal limited without departing substantially from claim and equivalency range
In the case of scope, the present invention is not limited to specific details, representational equipment and shows shown here as the diagram with description
Example.
