The course of work of this used for electric vehicle fault remote-measurement and control device is as follows:
(1) before using to sign indicating number
At first produce algorithm through password together and form unique Crypted password by works code and series number;
Write EPROM in the sheet then, make the remote measurement controller produce corresponding unique Crypted password;
Produce the highly confidential rolling code of 32Bit by former code, Crypted password and synchronous code etc. through the KEELOQ algorithm for encryption again;
Confirm unique Crypted password that the remote measurement controller produces by fault alarm parts " study ";
Sequence number and synchronization value with institute's " study " stores in the flash chip 9 of master controller after encrypting at last, finishes the sign indicating number process.
(2) on duty after flame-out the parking
Enter state on duty: electric automobile stops working when stopping; electric automobile during traveling sends low level signal with direct supply; with the electronic switch closes on the master controller 1 normalizing line power supply that is arranged on the fault alarm parts, connect this warning device power supply, make warning device enter state on duty.The single-chip microcomputer 5 of master controller has idle sleep function, and state-transition on duty is " sleep state ", waits for " waking up " of remote measurement controller.
(3) single-chip microcomputer of master controller is waken up by the remote measurement controller
After the microswitch of pressing the steering order input block 12 of remote measurement controller as the motorist sent the safety detection instruction, transmitter unit 15 required to detect the safety case of electric automobile to fault alarm components, which transmits rolling code information.The receiving element 18 of fault alarm parts receives electric wave signal, flow to rolling code decoding chip 19 after treatment and decode, decoded encrypted message with the rolling code that is stored in behind the sign indicating number in the flash chip 9 is checked, if not right, then do not comprehended.If it is right, the single-chip microcomputer 5 that then wakes master controller up sends instruction, respectively electricity leakage sensor 22, leakage sensor 23, temperature sensor 24 are detected, be 0.5 second detection time, and the dangerous threshold value of storing in advance in the data of acquisition and the X5045 flash chip 11 compares.
(4) the fault alarm parts are reported to the police
If the data that obtain greater than dangerous threshold value, threaten the person and car body safety, the single-chip microcomputer 5 of master controller passes through fixed code coding chip 20 establishment fixed code with fault type, by transmitter unit 21 modulate emission carrier waves; The remote measurement controller receives electric wave information and draws concrete fault type through 16 decodings of fixed code decoding chip, send the different sounds according to dissimilar hummers by alerting signal output unit 17, the LED lamp is shinny simultaneously, break down to motorist's prompting, the sound stops after 20 seconds, and pilot lamp extinguishes.The single-chip microcomputer 5 of master controller enters the wait exception handles automatically simultaneously, waits for that the remote measurement controller sends instruction, if do not send instruction, returns state on duty automatically after 10 seconds.
If the data that obtain are less than dangerous threshold value, the single-chip microcomputer 5 of master controller is with the no risk of disturbance fixed code of fixed code coding chip 20 establishments, by transmitter unit 21 modulate emission carrier waves; The remote measurement controller receives electric wave information and draws no risk of disturbance through fixed code decoding chip 16 decoding, sends the sound of no risk of disturbance by the hummer of alerting signal output unit 17, and while LED lamp is shinny, points out no risk of disturbance to the motorist.
(5) processing of fault
After the motorist accepts alarm, can notify the specialized maintenance personnel to carry out site disposal, the microswitch that also can press the steering order input block 12 of remote measurement controller within 10 seconds once more sends the risk of disturbance processing instruction, risk of disturbance processing unit 7 by the fault alarm parts carries out emergency treatment, the normally closed contact ZC of the safe contactor in the power brick 2 is discharged, from being connected of power brick 2 internal cutting ofves and external high pressure circuit, avoid causing danger to guarantee safety
(6) releasing of state on duty
When electric automobile was in transport condition, electric automobile during traveling provided high level with direct supply, and the electronic switch on the master controller 1 normalizing line power supply disconnects, the power supply of disengagement failure warning piece, thus remove its state on duty.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the present invention is determined by claims of being submitted to.
