Abstract

A car-crarried antitheft system features use of public digital communication network without dedicated communication base and monitor center. As the "110" alarm and control centers are set up based on geographical regions, no matter where the stolen car is running, the information about the car can be immediately known by "110" alarm and control centers, so allocating the car. Its advantages are wide covered area and high utilization rate.

Description

Anti-theft system installed in car

The present invention relates to a kind of Vehicle Anti-Theft System of forming by digital communication network, 110 warning command centres, in-vehicle communication system.

In existing background technology, automobile mostly adopts CNS anti-theft system and global position system CPS.The CNS automotive theft proof system is applicable to the big or middle city of traffic control center, and it is that camera monitoring system with traffic intersection is a support, and stolen vehicle is sought in monitoring, and this is as looking for a needle in a haystack, and case-solving rate is not high, and protection face is little, and whole system is expensive.Global position system CPS is the most perfect monitored control system that promote present various places, this system has accurate positioning, broad covered area, advantage that case-solving rate is high, but, whole system costs an arm and a leg, and the satellite ground station of native system special use must be arranged, the car owner can't be directly acquainted with the situation of stolen vehicle.

The objective of the invention is to: provide a kind of cheap and can utilize 110 warning command centre broad covered areas of existing common number communication network and various places, the anti-theft system installed in car of advantage that degree of utilization is high to numerous car owners.

Technical scheme of the present invention is: said anti-theft system installed in car, by multiple antitheft detector, detectable signal receiving device, alerting signal feedway, voice device, monitoring device, remote controller and handle in-vehicle communication system that the central processor CPU of these signals forms and the common number communication network of postal and telecommunication entities is formed, in in-vehicle communication system, antitheft detector in the car is multiple antitheft detector, it is made of jointly shock sensor and infrared ray curtain wall, and the two is independent mutually.The antitheft detector of two kinds of forms is respectively with wired mode connection signal coffret, pass through circuit, the signal transmission interface CPU interior with placing car communicates, the signal of handling through CPU communicates with the vehicle-mounted digital phone by coupled analogue to digital conversion coffret, the vehicle-mounted digital phone is both in in-vehicle communication system, simultaneously also in the common number communication network, by the common number communication network, 110 warning command centres of vehicle-mounted digital phone and car owner's mobile phone, Home Telephone, WorkPhone, pager and vehicular seat can connect warning automatically.The communication tool of 110 warning command centres of car owner and vehicular seat is by the common number communication network, can send instruction by direct connection vehicle-mounted digital phone, the vehicle-mounted digital phone feeds back to CPU to the instruction that receives by the analogue to digital conversion interface, and CPU can activate voice device and the monitoring device that communicates with CPU in the car according to the instruction that receives.

The invention has the advantages that: the communication base and the monitoring and control centre that need not to set up again native system, 110 warning command centres and car owner can utilize the common number communication network to recognize the situation of stolen vehicle whenever and wherever possible, because 110 warning command centres divide with the zone, so the on-site 110 warning command centres of stolen car can promptly find stolen vehicle, thus the zone location of realization stolen vehicle.

Below in conjunction with accompanying drawing anti-theft system installed in car of the present invention is described in further detail:

Fig. 1 is the block scheme that the in-vehicle communication system in the anti-theft system installed in car of the present invention combines with the common number communication network:

In Fig. 1, when the shock sensor 5 in the native system 22 is worked, can come out the abnormal vibration test of vehicle, for example: when vehicle parking, if the car stealer moves vehicle with forklift or alternate manner, shock sensor 5 can be passed to coffret 7 by lead 6 with the form of signal, passes to the central processor CPU 20 that places in the car by circuit 4 again; Also be provided with the infrared ray curtain wall of being made up of a plurality of infrared detectors 10 in car simultaneously, infrared ray curtain wall 10 links to each other with coffret 7 with lead 9.When infrared ray curtain wall 10 was started working, if the car stealer enters vehicle, infrared ray curtain wall 10 can be passed to coffret 7 through lead 9 from different orientation with the signal that detects, and is transferred to the CPU20 that places in the car by circuit 4 again; After CPU20 receives the signal that coffret 7 transmits, at once with store within it relevant data relatively and judge, when being compared numerical value and exceeding setting value, send instruction by CPU20, connect both in in-vehicle communication system 22 by analogue to digital conversion interface 19, while is the vehicle-mounted digital phone 18 in the common number communication network of postal and telecommunication entities 12 also, at this moment, in-vehicle communication system 22 is automatically connected with postal and telecommunication entities 12 by vehicle-mounted digital phone 18, and enter the common number communication network 17 that spreads all over the country, utilize common number communication network 17, vehicle-mounted digital phone 18 can be put through the 110 warning command centres 11 that are stored among the CPU20 automatically, the mobile phone 13 that the car owner carries, dwelling house 14, WorkPhone 15, and the communication number of pager 16.The watch keeper of 110 warning command centres and car owner can find the residing situation of vehicle in time, and utilize common number communication network 17 and vehicle-mounted digital phone 18 to connect, send instruction by vehicle-mounted digital phone 18 and digital to analogy conversion coffret 19 to CPU20, activate voice device 1 and monitoring device 2 in the anti-theft system installed in car respectively by circuit 21 and 3 then.Voice device 1 has that recording, voice store, read-write capability and the function called by CPU20 repeatedly; Monitoring device 2 has the function of being called and monitor sound in the car by CPU20; In native system, also be provided with remote control equipment (RCE), forget when starting native system, or the car owner is when automobile is robbed state, can send instruction for coffret 7 with remote controller 8 and start CPU20 by circuit 4 and make native system enter mode of operation when the car owner leaves vehicle.
