Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation towards battery management system；
Fig. 2 is the structural representation of data communication companion.
Detailed description of the invention
As it is shown in figure 1, be towards battery management system, comprise following components, data center, communication network, intelligence
Data communication companion, battery management system (BMS) and battery bag.
Generally, battery management system does not possess and carries out the ability of data exchange with data center, and intelligent data
Companion is as expansion module in communication, can be connected with data center by battery management system, carry out data exchange.Towards electricity
In pond management system, the message data of BMS being divided into two classes, the first kind is alarm fault message, and this category information needs real-time
It is uploaded to data center, and obtains the feedback information of data center, return to BMS；Equations of The Second Kind is battery data information, such letter
Breath is the life cycle in order to monitor electrokinetic cell；Simultaneously communication companion can according to signal intelligence to two class message datas at
Reason, such as, when the companion that communicates runs into communication failure, intelligent data communication companion believes in the data receiving battery management system
After breath, data message will be differentiated, and according to priority principle, data be carried out the process storing or forwarding.
After data communication companion is that BMS shakes hands successfully, will be connected with BMS by communication bus, and be constantly in wait
Obtain the state of BMS communication data.After data communication companion gets the communication data of BMS, enter and obtain network connection side
The state of method, i.e. by the network environment residing for Intelligent hardware identification at present.After identification, data communication companion examines starting
Disconnected received BMS communication data.
First determine whether whether received information is alarm fault message, if alarm fault message, i.e. judge current institute
The network environment at place.If now cable network accesses, then send data to data center by cable network module；If no
Cable network accesses, then continued to determine whether that wireless network accesses, and repeats aforesaid operations；If wireless network is equal with cable network
Do not access, the most directly send data to data center by global mobile communication mixed-media network modules mixed-media, and detect whether data pass
Defeated success.If bust this, then continue passback, and record the frequency of failure, when the frequency of failure adds up unsuccessfully more than the transmission set
During number of times, report bust this to BMS, and record alarm fault message, finally return to the state obtaining BMS communication data；
If transmission success, then return directly to BMS communication data state.
If it is determined that be not then to determine whether battery data information during alarm fault message.If battery data information,
I.e. judge the most residing network environment.If now cable network accesses, then send data to number by cable network module
According to center；If not having cable network to access, then continuing to determine whether that wireless network accesses, having repeated aforesaid operations；If now not having
There is network insertion, then battery data is stored to data memory module.If it is determined that to now having already accessed in network, i.e. go up
Pass the battery data information in data memory module, until all battery data information uploaded in data memory module are uploaded
To data center.
As in figure 2 it is shown, be intelligent data communication companion's structural representation of the present invention.Wherein battery management system and intelligence
Data communication companion has three class holding wires to connect, and respectively power bus, IO shakes hands port and communication bus.Market at present
On BMS major part all powered by 12V lead-acid battery, intelligent data communication companion power bus can be with carry at this 12V lead
On acid battery power bus.IO shakes hands port detection-phase of shaking hands when BMS is connected with intelligent data communication companion.At IO
Shake hands in port, can be one by the holding wire of level triggers, at BMS end, this I/O port is by the resistive pull-downs of 10 kilohms
Ground connection；At intelligent data communication companion's end, this I/O port is the high level of a 12V；When BMS detects this high level, i.e.
Think that intelligent data communication companion is linked in the middle of BMS.Communicating after companion shakes hands successfully with intelligent data at BMS, BMS will pass through
The mode of communication bus and data communication companion exchange data.
Above-mentioned whole world mobile network's module, wireless network module, cable network module are relation in parallel, and by embedded
Processor selects the interface channel with data center by data transmission channel handover module.The whole world mobile network can be by
The hardware system of SIM900A composition, and support the function such as note, GPRS data transmission.Wireless network can be by CC3200 group
The hardware system become, supports the AP/STA pattern of WIFI.The hardware system that cable network can be made up of ENC28J60, externally
Reserve RJ45 interface.
Form it addition, the data memory module of intelligent data communication companion can be two SD cards with SDIO interface.
The data received, when a SD card is in reading state, can be stored to second SD card by two SD card rotation work.This
The SD card at place is equivalent to fifo queue, after the storage of SD card is full, by again at the start memory location original number of covering of SD card
According to.After network signal being detected, and after having been uploaded by the battery data stored, will empty SD card, wait re-writes
Battery data information.
