Algorithm is known together with distributed node to generate the peace for guaranteeing data transmission and access with more new data, in the way of cryptography
Entirely, it is programmed using the intelligent contract being made of automatized script code and distributed basis frame that one kind of operation data is completely new
Structure and calculation.
2) car owner inquires power battery state using vehicle-mounted BMS terminal or mobile phone application, and system is verified identity information, tested
After card passes through, block catenary system is transmitted the request to；
3) car owner selects power battery parameter to be detected, and block catenary system is required to calculate, be analyzed accordingly according to car owner
Parameter, and compared with the standard operating conditions of default, relevant criterion is inputted in system, i.e., power battery is just
It is each to join when the range of the variation tendency of each parameter and each changeable parameters, i.e. power battery work normally under normal working condition
Several concrete conditions；
The block catenary system server will preset the data expression side of the analysis method and result of various detection parameters
Method；
4) after comparing, it was therefore concluded that, it is indicated that it whether there is problem, if out of question, this service terminates；If there is asking
Topic, existing problem and the failure being likely to occur that system provides is compared and analyzed, and screen solution, be in system
Interior input power battery common failure and corresponding solution；
5) after solution screening, car owner first voluntarily carries out failure solution according to prompt, if problem is unresolved, basis
System prompt selects the vehicle maintenance centre in nearest place, or dials telephone number and seek On-Site Assistance, be in advance in system
The information of a large amount of maintenance centers is inputted, mainly includes address, contact method, main business, business hours；
6) after, car owner is that this status inquiry is evaluated, to obtain better service later.
A kind of power battery state monitoring apparatus based on block chain, comprising:
Registration module: enter block chain for car owner's registration, obtain unique identification；
Memory module: each parameter values of power battery detected for receiving detection terminal；
Inquiry terminal: the application of inquiry power battery state parameter is carried out for car owner；

Specific embodiment
It is the technology path of the power battery state monitoring method provided in an embodiment of the present invention based on block chain shown in Fig. 1
Flow chart.It comprises the steps of:
Step S101: car owner's registration enters in block chain, and will test the power battery supplemental characteristic that terminal detects and upload to
Block chain.
Optionally, detection terminal is preferably power battery management system (BMS), and now the BMS management system of mainstream can
Enough various data for more comprehensively detecting power battery, the precision detected also can provide biggish side to relevant enterprise
It helps.The power battery parameter of detection should include voltage, electric current, remaining capacity etc..
Step S102: car owner inquires power battery state using inquiry terminal application, and system verifies identity information, and determination is
It is no to receive request.
Car owner is connected by selected terminal with block chain, is then filed an application to system, and system pop-up identity is tested
Information is demonstrate,proved, identity information when car owner is according to registration logs in, and block catenary system carries out Information Authentication according to the relevant technologies, tests
It demonstrate,proves successfully, then receives the application inquiry of car owner.If verifying is unsuccessful, verification information mistake is prompted, terminates this application.
Optionally, inquiry terminal may be selected to be smart phone (such as Android phone, i0S mobile phone), tablet computer, the palm
Upper computer and mobile internet device etc..
Step S103: car owner selects power battery parameter to be detected, and block catenary system requires to count according to car owner
It calculates, analysis relevant parameter, and is compared with the standard operating conditions of default.
According to prompt, car owner selects the power battery relevant parameter for needing to detect, and block chain is required according to car owner, first to vehicle
Mainly the data of detection is asked to carry out calculating analysis, obtains parameter variation tendency and variation relation；Then first time comparison is carried out,
With the work trend of the relevant parameter under the standard operating conditions of system storage, variation range is compared and analyzed.
Step S104: after comparison, it is indicated that whether there is problem, if out of question, this service terminates；If there is asking
Topic then carries out second and compares, find there are the problem of；Then third time comparison is carried out, solution is sought.
By comparing for the first time, the relationship changed with relevant parameter under standard operating conditions is obtained, and analyse whether to it
There are problems, and problem then provides dynamical system and works normally report, while this application poll-final if it does not exist；If there is
Problem will then be compared for the second time, and existing problem and the failure being likely to occur that system provides are compared and analyzed, looked for
It has same or similar failure；Then third time comparison is carried out, is compared and analyzed with the fault resolution of system storage,
And screen best solution.
Step S105: after solution is screened, car owner first voluntarily can carry out failure according to prompt according to degree of difficulty
It solves.This service terminates if solving；If problem is unresolved, the 4th comparison is carried out, the vehicle stored according to system
Maintenance center, selection distance it is nearest and vehicle maintenance centre that be suitble to be diagnosed to be breakdown maintenance carry out live dimension
It repairs；If vehicle has been not normally functioning, selected vehicle maintenance centre telephone number can be dialed seeks maintenance personal and come
Solve on site failure.
Step S106: after failure solves, car owner evaluates for this status inquiry, including to block chain server
Evaluation and evaluation to selected maintenance center.Block chain server is evaluated, to be carried out to block chain server
Preferably optimization stores the failure and more fault solutions being more likely to occur, so that later period inquiry is more square
Just comprehensively；Then selected vehicle maintenance centre is evaluated.The above information on services the whole network will broadcast in block chain, allow more
It is portable that more car owners realizes addition block chain bring, so that more car owners be guided to be added.
