Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings:
As shown in figure 1, a kind of be based on 4g network remote calibration system, including remote monitoring client 1, remote monitoring server 2,
Remote monitoring terminal and battery management system, battery management system includes bms main frame, bms slave and battery bag, and remote monitoring takes
Business device 2 is interconnected with remote monitoring client 1, remote monitoring terminal respectively, and bms main frame is interacted with remote monitoring terminal even
Connect；Described remote monitoring terminal includes 4g remote terminal module 3, can mixed-media network modules mixed-media and microprocessor module (arm 3960-l),
This can mixed-media network modules mixed-media is carried out data transmission with bms main frame, bms slave by can grid line.Described remote terminal module 3 is at least
Compatible mobile 2g, 3g, 4g network, UNICOM's 2g, 3g network.
Remote monitoring client 1 is used for providing inquiry and calibration interface to user and keeper, and wherein, inquiry includes vehicle
Real-time and passing geographical position, the extreme value information of battery, monomer information and vehicle other information；Demarcation is included to bms main frame
Relevant parameter demarcation and the demarcation of host policies parameter；This geographical position includes the coordinate position that can directly display on map
With gps coordinate；Extreme value information includes highest monomer voltage, minimum monomer voltage, highest monomer electric current, minimum monomer electric current,
High monomer temperature, minimum monomer temperature and other information；Monomer information includes battery cell temperature, monomer voltage and other letter
Breath.Remote monitoring server 2 major function is service data library, and next is also equipped with communication function；Wherein, database program
Possess the storage to data, inquiry, calculate and analytic function.
Bms main frame is used for communicating with entire car controller to obtain whole vehicle information, and the whole vehicle information of acquisition is sent to far
Range monitoring terminal, wherein, whole vehicle information includes VMT Vehicle-Miles of Travel, running velocity and other information.Bms slave is used for adopting
Set battery package informatin, and the battery collecting package informatin is sent to remote monitoring terminal and bms main frame.Remote monitoring server
2 are used for the data receiving is processed, and by the data storage processing in database, to facilitate user to pass through client
The current information that software real-time query vehicle travels.
Long-range demarcation is similar to the reverse of long distance control system communication link in fact.Refer to Fig. 2, Fig. 2 is according to the present invention
The long-range calibration system flow chart of embodiment.
A kind of scaling method based on 4g network remote calibration system, specifically includes following steps:
(a) in long-range calibration system, when user propose demand to change host parameter when, can according to the real-time soh of battery pack,
It is achieved in reasonable interval, such as client needs to stop immediately charging, and can terminate remotely realizing charging；Or when management
When member needs long-range demarcation bms host parameter, the such as calibration of battery soc, can be in long-range real time calibration up-to-date soc value.
B () user and keeper can select remotely to demarcate in client software, click button enters long-range demarcation immediately
Interface, needs the parameter of the corresponding change of input, such as input battery soc value is 90, clicks on and determine after the completion for the treatment of parameter calibration.
C (), after demarcation information determines and sends, treats that the message server in remote monitoring server 2 receives to information weight
Structure, is sent to the java background service in remote monitoring server 2 by message-oriented middleware mode.Message server major function
It is that the product data developed based on different platform are carried out conversion communication, function is similar to switch, mainly realize service herein
Device is transmitted with the communications and data of java background service.
D () java background service is run and is communicated with remote monitoring terminal by udp agreement.Including shaking hands, weight
Pass and other mechanism.Java background service gets No. id of remote monitoring terminal first from demarcation information, subsequently enters with it
Row is shaken hands, and shakes hands and starts actual data transmission after having successfully received response bag.Because udp packet transmission primaries is at most up to thousands of
Byte, so data can complete to transmit by a bag, after the completion of data is activation, terminal carries out data check, confirms that data is accurate
Confirmation bag is sent, background service completes task after receiving confirmation bag after errorless.If background service is at the appointed time
Do not receive confirmation bag, meeting log-on data retransmission mechanism, send complete data packet again, wait confirmation.If repeatedly
Send and still do not receive confirmation bag then it is assumed that network failure, data is activation is unsuccessfully.
E () remote monitoring terminal receives accurate calibration information after, bms master can be forwarded the data to by can mixed-media network modules mixed-media
Machine.Data transfer mode is similar to (d), as shown in Figure 3.Terminal sends handshaking information bag first to main frame, and failure of shaking hands can again
Shake hands until reach maximum shake hands number of times terminate demarcate.Shake hands and then can carry out data transmission, because can procotol number after success
According to wrapping, a secondary data is maximum to only have 8 bytes, so needing to be divided into how bag is transmitted.Can wait corresponding after sending a bag data
Confirmation bag, does not receive and just resends, if all not receiving confirmation bag in maximum number of times of transmission, direct
Jumping to shakes hands restarts to demarcate.Conversely, then continuing the transmission of next bag data, confirming until all packets all complete to send
And confirmation.
F () bms main frame receives corresponding demarcation information after, corresponding parameter is changed, such as by battery pack slave number from 6
It is changed to 4；Or receive information requirements change host policies, such as stop charging, main frame can disconnect charge relay immediately and stop
Only charge.So far long-range demarcation completes, and whether user can also change in the demarcated host parameter of client real-time query.
Embodiment described above is only that the preferred embodiment of the present invention is described, the not model to the present invention
Enclose and be defined, on the premise of without departing from design spirit of the present invention, the technical side to the present invention for the those of ordinary skill in the art
Various modifications and improvement that case is made, all should fall in the protection domain of claims of the present invention determination.
