Description
Technical field
Battery thermal runaway is prevented to examine the present invention relates to new energy car battery safety monitoring technology field, more particularly to one kind
The program control system of examining system error starting.
Background technology
A kind of new energy car battery that is used for is disclosed in Chinese patent application prospectus, CN106066457A to pacify
The battery thermal runaway detecting system in full monitoring technology field.The system includes intelligence instrument, background monitoring center and is arranged at electricity
Thermal runaway detector inside the case of pond, it is characterised in that the thermal runaway detector includes data acquisition device and master control set；
The data acquisition device is used to gather the current thermal runaway parameter of each detection node inside battery case and sent to described
Master control set；The master control set includes core cpu processing module, communication transmission module, performs device control module；The invention
A kind of battery thermal runaway detection method is further related to, including judges whether flame value is more than or equal to flame threshold set in advance；It is right
Temperature, gas and smog parameter carry out data filtering processing, extract characteristic value；By above-mentioned parameter integrated treatment, determine that startup is gone out
Fiery device fire extinguishing provides pre-warning signal.Beneficial effect is：Detecting system is accurately held fire extinguishing opportunity, hidden danger can be made timely
Disposal.
But the system in actual installation, debugging process due to hardware, software and the factor such as artificial, fire extinguisher can be caused
There is error starting, not only influence the battery thermal runaway detecting system normal work, and can further damage battery in battery case
And other devices.Conventional anti-error startup method is main to be realized in terms of hardware and software two, such as hardware aspect：Add to equipment
Plus physical locks, artificial false touch is prevented using button series connection, data jump etc. caused by increase filter circuit filtering interference signals；Or
Software aspects：Initiation value, initial detecting, diagnostic points detection etc. are set.And conventional hardware and software method, one side hardware
Increase can improve equipment cost, and structure is more complicated also to increase maintenance difficulties, improve system fault rate, the application increase of software
System loading and EMS memory occupation frequency；On the one hand it is to be only capable of solving the problems, such as system error starting caused by single factors；On the other hand
The realization of other functions of system can be influenceed.
The content of the invention
The technical problem to be solved in the present invention is that system error starting caused by solution many factors can be integrated by providing one kind
And do not influence the program control system of the realization of other functions of system.
To solve the above problems, preventing battery thermal runaway detecting system from missing based on programme controlled the invention provides one kind
The control system of startup, the system by original " thermal runaway detector's status inspection software " increase " lock status inquiry ",
" locking " and " unblock " function, the inspection software is integrated in core cpu processing module, controls the trip bar of detecting system
Part.Wherein, locking flow is：Lock signal enabling and lock flow, matching needs the battery case number (CN) locked, after the match is successful, entered
Row CRC check is CRC, after verifying successfully, and system display is locked successfully；If battery case number (CN) matches unsuccessful or school
Failure is tested, system, which is returned, locks failure, exits locking flow.Thermal runaway detector under locking protection state, works as progress
Automatic start, manually boot or test fixture start fire extinguisher when, whether system automatic decision locks, and starts if unlocked and goes out
Firearm, can not start fire extinguisher, no matter whether fire extinguisher starts, system all can if thermal runaway detector is in " locking " state
Recording exceptional data.Unlocking flow is：Unlocking signal starts unblock flow, and the match is successful with battery case number (CN), CRC check success,
System failure, system is as good as regular data, unlocks successfully；Otherwise, any of the above process is unsuccessful, that is, returns to unblock failure, move back
Go out to unlock flow.Thermal runaway detector can be locked before dispatching from the factory, until after the installation and debugging of finishing device, then solved
Lock.Thermal runaway detector in locking state, any factor occurred during dispatching from the factory to completion installation and debugging causes
Error starting, all will terminate startup because detecting system and being in locking state in start-up course, and other work(of the device
Can be such as warning function, fault diagnosis functions, record " manually booting Backup Data " function and record " fire extinguisher startup backup number
According to " function etc., can normally use, not influenceed by lock function.
As a further improvement on the present invention, for convenience of the scene unblock during practical set, for depot, it can pass through
Handheld device is set up communication with the core cpu processing module of thermal runaway detector and is connected, so as to unlock the same.
The program control system of battery thermal runaway detecting system error starting is prevented the invention provides a kind of, is not influenceing
On the basis of other functions of uniting, by the anti-locking system error starting of procedure lock, the process is simply easily realized, is quit a program after locking
Take, to system feedback locking state signal when there is fire extinguisher enabling signal in the external world, system degree is low.
