Description

Interior on a large scale antitheft and alarming GPS transmission monitor system implemented

Technical field: the present invention relates to Global Positioning System (GPS) GPS technology, it mainly is applicable to identification, monitoring and the warning of internal object on a large scale, especially to the burglar alarm of the open-air rod-pumped well in oil field.

Background technology: existing monitoring and alarming system to facility on a large scale all is to adopt single probe single-point to trigger, and has the high shortcoming of rate of false alarm.Moreover it is again wire transmission, has that difficulty of construction is big, cost is high, the shortcoming of the confidentiality difference of transmission data.And its alerting signal is that monobasic distributes, and has the slow shortcoming of back emergency reaction of reporting to the police.The scope of setting up defences of especially this system is little, is difficult to realize transregional networking.This system can't solve the antitheft and vandal-proof problem of monitoring anti-theft system self, and this system is once destroyedly just can not send alerting signal.

Summary of the invention: the objective of the invention is to develop a kind of on a large scale to interior antitheft and alarming GPS transmission monitor system implemented, it is the GPS technology that this system adopts Global Positioning System (GPS), can realize burglar alarm and locating and monitoring to facility on a large scale, it adopts the two index monitoring of two probes to facility, so rate of false alarm is low, and alerting signal can polynaryly distribute, so handle can be in time for emergency reaction, and it also has the function of anti-theft and anti-damage to burglar alarm self.The present invention is made up of the user terminal 7 of infrared sensor 1, shock sensor 2, dual signal collection analysis processing host 3, GPS transmitter 4, gps satellite 5, GPS network processes center 6, reception alerting signal.Infrared sensor 1 is made up of infrared sensing circuit 8, housing 10, the infrared receiver component D of infrared sensing circuit 8 ₂Be installed in opening 12 places in the housing 10, the output terminal of infrared sensing circuit 8 links to each other with the input end of dual signal collection analysis processing host 3, and infrared sensing circuit 8 is installed in the housing 10, and housing 10 is arranged on the monitored facility.Shock sensor 2 is made up of vibration-sensing element JD, housing 15, and vibration-sensing element JD is fixed in the housing 15, and the output terminal of vibration-sensing element JD links to each other with the input end of dual signal collection analysis processing host 3, and housing 15 is fixed on the monitored facility.Dual signal collection analysis processing host 3 is made up of the tamper-proof circuit 9 of main frame, housing 13, signals collecting and screening circuit 17, central processing circuit 18, function setting and relieving circuit 19, clock generating and signal amplification circuit 20, and dual signal collection analysis processing host 3 is installed in the housing 13.The tamper-proof circuit 9 of main frame is by a normally closed contact K ₁Form K ₁Be installed between the loam cake 16 and box body 21 of housing K ₁Output terminal link to each other with an input end of signal processing and analysis treatment circuit 17.The output terminal of dual signal collection analysis processing host 3 links to each other with the input end of GPS transmitter 4.GPS transmitter 4 communicates by antenna 22 launching electromagnetic waves and gps satellite 5.The electromagnetic wave of gps satellite 5 emissions receives by the receiving antenna 23 at GPS network processes center 6.GPS network processes center 6 is made up of alerting signal receiving processing circuit 24 and the polynary distributor circuit 25 of information, the input end of the polynary distributor circuit 25 of output termination information of alerting signal receiving processing circuit 24, the output terminal of the polynary distributor circuit 25 of information joins with the input end of the user terminal 7 that receives alerting signal.The user terminal 7 that receives alerting signal is made up of 110 alarm centers 29 of GSM website 26, Internet 27, paging centers 28, telecommunications network, the antitheft processing support system 30 of telecommunications network.Because the receiving element D of the infrared sensor 1 that the present invention adopts ₂Any object is the hotness infrared eye, no matter all can give off the strong and weak infrared ray that does not wait because of its surperficial temperature is different; Also because the difference of object, the Infrared wavelength of its radiation also has difference, when human body or other object enter search coverage, originally it is destroyed to stablize constant heat radiation environment, produce the heat radiation of a variation, infrared sensor receives this information after send alerting signal after amplifying, handle, analyzing.Shock sensor 2 utilizes the equilibrium principle of vibrations, to shake receiving element is contained on the monitored thing, because saboteur's desire must be to applying external force in fact when destroying monitored thing, also must produce flashy vibrations variation this moment, this variation is promptly sent alerting signal after the amplification of reception of vibrations receiving element and main circuit, analysis, the processing.Because dual signal collection analysis processing host is only just sent alerting signal when two sensors of different nature are all reported to the police, so reduced rate of false alarm.Again since in the central processing circuit storage electronic chart and the corresponding software thereof of monitored region are arranged, so contain the particular location of destroyed facility in the information that it sends, arrive in the very nick of time and handle in order to personnel.Also because the alerting signal of GPS network processes center 6 after will handling carried out polynary distribution, make mobile phone, PC, beeper, 110 alarm centers, antitheft processing support system can both receive alerting signal simultaneously, so emergency processing is just timely, the degree of the destroyed loss of monitored thing is just light.Reached facility in has on a large scale been realized unmanned, and purpose that can safeguard protection.Especially solved the problem that anti-theft monitoring system self goes to pot and also can report to the police.This system can also carry out duplex communication, is sent by the monitored thing of mind-set in the GPS network processes and removes monitoring or the instruction of initiatively patrolling and examining.
