Fig. 2 is the functional block diagram of photoelectricity processing unit in the utility model automotive theft proof system;

Fig. 3 is signal decoding and a comparing module functional block diagram in the utility model automotive theft proof system.

The specific embodiment

Please with reference to Fig. 1, Fig. 1 is the functional block diagram of the utility model automotive theft proof system.Automotive theft proof system comprises optical signal launcher 1, and said optical signal launcher can be launched optical signal, and this optical signal comprises the LED optical signal; Photoelectricity processing unit 2 and blocking device 3.

When needs lock said blocking device 3; Send locking optical signal by said optical signal launcher 1; The locking optical signal that the said optical signal launcher 1 of said photoelectricity processing unit 2 receptions sends also is decoded as binary data with this locking optical signal; Binary data that the comparison decoding obtains and preset locking binary data; Then export lock control signal to blocking device 3 when the binary data that obtains when preset locking binary data and decoding is consistent, blocking device 3 locks according to this lock control signal; When the binary digital signal that obtains when preset locking binary data and modulation was inconsistent, said photoelectricity processing unit 2 can be failure to actuate and also can be exported an alerting signal.This alerting signal can be audible alarm information and also can be the literal alarm message.

When needs are opened said blocking device 3; Send the unlatching optical signal by said optical signal launcher 1 equally; Also should open optical signal is decoded as binary data to the unlatching optical signal that the said optical signal launcher 1 of photoelectricity processing unit 2 receptions sends; Binary data that the comparison decoding obtains and preset unlatching binary data; Then export when the binary data that obtains when preset unlatching binary data and decoding is consistent and open control signal and give blocking device 3, blocking device 3 is according to this unlatching control signal unlatching; When the binary data that obtains when preset unlatching binary data and decoding was inconsistent, said photoelectricity processing unit 2 can be failure to actuate and also can be exported an alerting signal.

Open optical signal and locking optical signal can be consistent also can be inconsistent; When the unlatching optical signal is consistent with locking optical signal; The locking binary data of then presetting in the photoelectricity processing unit 2 is also consistent with the unlatching binary data, at this moment, comprises also in the photoelectricity processing unit 2 that judge module is to judge the state of this blocking device 3; When judge module detects blocking device 3 and is in opening; Photoelectricity processing unit 2 receives optical signal and this blocking device 3 of the consistent back locking of comparison, and when judge module detected blocking device 3 and is in the lock state, photoelectricity processing unit 2 receives optical signal and this blocking device 3 is opened in the consistent back of comparison.In the present embodiment, being tightening security property, is the example explanation to open optical signal and locking optical signal inconsistent, does not therefore comprise judge module in the said photoelectricity processing unit 2.

Optical signal launcher 1 can be independent optical signal transmitter, also can be integrated in mobile phone, panel computer etc. and carry in the mobile device of LED light-emitting device.When optical signal launcher is integrated in the mobile device, saved the equipment such as mechanical type key or infrared emission key of the extra setting of existing automotive theft proof system.

Please with reference to Fig. 2, among Fig. 2, said photoelectricity processing unit 2 comprises signal detection module 20, signal processing module 21 and signal decoding and comparing module 22.To lock the treating process that said blocking device 3 is example explanation the utility model, the locking optical signal that optical signal launcher 1 sends is the locking optical signal of high-frequency flicker, and signal detection module 20 detects and exports it to signal processing module 21 behind the locking optical signal of this high-frequency flicker and carry out processing such as denoising, amplification, interference protection; Locking optical signal after the processing exports signal decoding and comparing module 22 to; Signal decoding and comparing module 22 at first convert the locking optical signal of high-frequency flicker into current signal, and current signal converts voltage signal again into, when voltage is high level; For example when 5V or 3.3V; Be regarded as the positive rise of digital signal, when voltage is low level, promptly during 0V; Be regarded as the low level of digital signal, the digital signal that high-low level constitutes forms binary data through behind the manchester decoder.

Be preset with in signal decoding and the comparing module 22 and have specific binary data, when the binary data that obtains when this preset binary data and decoding was consistent, signal decoding and contrast module 22 output locking signals were to blocking device 3.In the present embodiment, blocking device 3 is an electromagnetic lock, when the binary data that obtains when preset two scale notation and decoding is consistent, and the connection of electromagnetic lock circuit, electromagnetic lock locks.

Therefore; The concrete block diagram of signal decoding and comparing module 22 is as shown in Figure 3, its specifically comprise be used for optical signal convert into current signal current signal modular converter 220, be used for current signal convert into voltage signal voltage signal modular converter 221, be used for according to voltage signal obtain digital signal digital signal acquisition module 222, to be used for digital signal decoding be decoder module 223, pre-stored module 224 and the comparing module 225 of binary data.

When needs are opened said blocking device, its flow process and locking type this, difference be signal that optical signal launcher sends different and correspondingly in the presetting module preset data different.

In the above-described embodiments, only the utility model has been carried out exemplary description, but those skilled in the art can carry out various modifications to the utility model after reading present patent application under the situation of spirit that does not break away from the utility model and scope.
