Abstract
The city safe guard information system consists of microwave sensor, position mark communication network and terminal center station. Its position mark communication network includes higher station signal receiving and transmitting branch, center station control command receiving branch and microwave sensor alarm signal receiving, control command loading and microwave modulating branch. The terminal center station is one bidirectional receiving and transmitting communication network terminal. The present invention is one wide-band and digital and analog compatible microwave transmission system with high noise immunity and it has the functions of bidirectional information transmission and wide-band TV image transmision.
Description
The present invention relates to a kind of city safe guard information system that utilizes microwave communication and computer combination.
Existing antitheft, robbery-defence alarm generally is made of jointly alarm transmission device and local telephone communication net.When the robber has been taken place, robbed bank, when place such as hotel, warehouse and motor vehicles, can incidence of criminal offenses information be sent to the police or predefined telephone terminal exactly by the local telephone communication net, for the criminal that investigates and apprehend quickly and efficiently of the police provides powerful guarantee technically.But traditional antitheft, anti-misfortune city safe guard device has following shortcoming: the first needs the Local Network as means of communication, influences telephone wire and normally uses, and increases user's financial burden; It two is can only the one way propagation warning message, and oppositely transfer control instruction; It three is to utilize the Local Network can only transmit the low frequency arrowband, and is limited to digital signal.
The purpose of this invention is to provide a kind of microwave transmission broadband, DA compatibility of utilizing, and city safe guard information system that can two-way transmission information.
The present invention is made up of microwave remote sensor 1, position mark communication network 2,3 and terminal center station 4,5,6; Described microwave emission sensor 1 is stolen, robs by detecting and transducer 8, controller 9, modulator 10 and the transmitter 11 of other danger signal are formed; The terminal center station is by the network terminal 4,5, and electronic chart 6 and customer database 7 are formed; It is characterized in that: position mark communication network comprises: transmission that is connected successively and reception antenna 12, amplifier 13, merit are divided amplifier 14, power splitter 15, transmission and reception antenna 16; This branch road can receive the station signal and be emitted to console for centralized control; Another output of described power splitter 15 divides an input of amplifier 19 to be connected with filter 17, amplifier 18 and another merit successively, but the control command that receiving center station directionization is come, and divide amplifier 19 minutes one route demodulators 22, decoder 23 and transmitters 24 and antenna 25 that control command is launched station signal antenna 12 in another routing amplifier 20, filter 21, the reception by described merit, this control command is mail to the next stop; The antenna 29 that receives the microwave remote sensor alarm signal divides amplifier 14, power splitter 15 and antenna 16 to be connected successively with receiver 28, modulator 27, emission upconverter 26, merit, UPC signal processor 30 is connected with modulator 27, be used for the load instructions signal, local oscillator 31 is connected with emission upconverter 26, and alarm signal is loaded on the microwave of preset frequency; This branch road can receive the User Alarms signal and mail to console for centralized control, and described terminal center station is two-way reception, emission communication network terminal, comprises that also a downlink signaling produces circuit 5; Described microwave emission sensor can be sensitive to vibration, temperature, voltage, pressure
The present invention compares with traditional city safe guard information system, has the following advantages:
1. dedicated network, interference-free, good in economic efficiency;
2. have two-way controlled function, can send instruction by central station, the controlled microwave emission sensor carry out to take precautions against action as: connect warning facility, locked antitheft door is cut off the electricity supply etc.;
3. native system can transmit wide band television image, and it is more extensive to make it purposes and function.

Fig. 1 is the theory diagram of city safe guard information system provided by the present invention;
Fig. 2 is the microwave emission sensor theory diagram that wood is provided by the city safe guard information system that is provided;
Fig. 3 is the position mark information bidirectional communication network theory diagram of city safe guard information system provided by the present invention.
The report to the police communication of (as bank, hotel) and central station of working method of the present invention mainly contains position mark station and dead point is reported to the police, the sharp moving point in mark station, position is reported to the police mark station, two kinds of positions and dead point is to utilize microwave network to set up, the system works principle: being various alarm sensors is moved by the strick precaution that the central station computer display alarm information also can oppositely be controlled alarm point by micro-filtration network and central station contact again.Wherein transducer can be various antitheft, anti-the antitheft of signal or family of bank, the fire prevention rescue information of robbing on the vehicle.The controller 9 of above-mentioned transducer 8 can be video camera or vehicle control element.Native system adopts the 770M transceiver, and is main with the real channel device of seeing short haul connection of micropower, makes some warning and locatees and do not have the dead point alarm signal of telephone wire to transmit, and also can adopt the 480MH transceiver, satisfies the requirement of different user
Moving point is reported to the police, and mainly is automobile.This alarm is called car alarm, can network, and can be used as the personal automobile alarm of independent use again.Under alert status, open car door, startup automobile or dilatory automobile and all will trigger alarm.When automobile was robbed, the driver can step on flush type switch or give the alarm by remote control keys; The also available remote controller of driver is realized functions such as automobile flameout parking as required.After the automobile driver leaves car or indoor unmanned when stolen, or when automobile or indoor the robbery, the password that system is about to alarm point is sent to central station with microwave network, or be sent to the station (secondary center station) that distributes with antenna, be sent to central station by the station that distributes again, after central station is received alarm cipher, immediately with the (automobile: for information about of alarm signal as vehicle, color, license plate number, the position, time, date, indoor: as the address, number, attribute-warehouse, bank, the householder, time, date) is presented on the screen, and alarm sound is arranged, and follow the tracks of the travel route of stolen vehicle.The data at everybody mark station of the Network Transmission of native system enter the receiving center of central station, and the distance of every some distribution is not more than 300M, and greater than 2KM, transmitting power is greater than 10MW to secondary center station transmitting range for mark station, position, EIRP＞1W.Microwave communication network receiving center: the microwave signal that receives each station that distributes, and flow to central station, sensitivity: NF≤2.5db, bandwidth: ± 0.1MHZ and ± two groups of 8MHZ, gain＞20db and 50db, frequently steady＜10-6 microwave communication network repeater station transmits the microwave signal at everybody mark station to center receiving station, the various instructions at receiving center station, transmit the surveillance television signal, emission control vehicle signal, repeating power 10dbm, 20dbm, each level of 30dbm, emissioning controling signal level 720dbm emission surveillance television signal level＞20dbm, 30dbm.
