Described motor vehicle electronic protective device with two kinds of remote-controlled modes also comprises the electric switch testing circuit that is between described single-chip microcomputer and the electric switch.

Described motor vehicle electronic protective device with two kinds of remote-controlled modes also comprises vibrating sensor and the amplifying circuit thereof that links to each other with described single-chip microcomputer.

Described motor vehicle electronic protective device with two kinds of remote-controlled modes also comprises the car door testing circuit that is between described single-chip microcomputer and the car door lamp.

Described motor vehicle electronic protective device with two kinds of remote-controlled modes also comprises the motor testing circuit that is between the described single-chip microcomputer and the motor neutral conductor.

Described motor vehicle electronic protective device with two kinds of remote-controlled modes also comprises the neutral gear testing circuit that is between described single-chip microcomputer and neutral gear line or the parking brake line.

Second purpose of the present utility model is achieved in that the erasable circuit that the decoder address is arranged between the decoder in described single-chip data output and the described paging information receiving system.

The erasable circuit of described address code comprises ternary electronic switch and data communication line, clock line, control line.

Operating principle of the present utility model and process are as follows: when remote information transmits by notifying from a phone call network, the paging information receiving system is like this to information process: after radio wave is received by antenna, by the paging information receiver information is handled, demodulate the audio frequency binary coded signal, delivering to decoder handles, decoder converts the audio frequency binary coded signal to the ASCII character signal after the decoding, be sent to central processing unit by synchronous serial interface behind phase inverter.When information when sending with the supporting remote controller of remote information receiving system machine, the remote information receiving system to information process is: radio wave is received after frequency selection circuit demodulates binary coded signal by antenna, again after amplification and rectification circuit is handled, deliver to central processing unit by the middle fracture IC1 of central processing unit.Central processing unit receives any one interrupt interface information, just the stored user cipher of these information and this machine relatively,, realize reporting to the police if relatively success then produces control action according to password, remove and report to the police, revise this secret sign indicating number, revise the decoder address code, be provided with antitheft, seek car, the independent key lock control of remote control starts vehicle, removes functions such as security settings.

The utlity model has two kinds of remote-controlled modes, the waste telecommunication resources of neither can hanking, very convenient driver operation again, can manage automobile anywhere or anytime again simultaneously, this device can accurately be judged the various states of vehicle intelligently, make corresponding action, and can strict execution guidance command.Arbitrarily the decoder address code of adaptation apparatus paging information receiving system makes this device can be applicable to various public paging network networks at any time, satisfies various places user's needs.
