Abstract
The utility model relates to a position marking communicating device of safety guarding information system, which comprises a branch circuit receiving and transferring the signal of an upper station, a branch circuit receiving the control instruction transferred from the direction of a central station, a branch circuit receiving the microwave alarm signal and loading the control instruction and a microwave modulating branch circuit. The utility model forms the safety guarding information system with a microwave alarm signal generator and a terminal central station, can transfer the wideband and the digital-to-analog compatible microwave signals and transmits information from two directions.
Description
The utility model relates to a kind of communication device that utilizes the city safe guard information system of 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 local network, but investigate and apprehend quickly and efficiently for the police that criminal provides powerful guarantee technically traditional antitheft, anti-ly rob the city safe guard device following shortcoming arranged: the first needs the Local Network as means of communication, influence telephone wire and normally use, increase 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 utility model provides a kind of microwave transmission broadband, DA compatibility of utilizing, and the two-way position mark communication device of safe guard information system that can two-way transmission information
The utility model comprises: signal transmission/reception antennas 1, merit divide amplifier 2, power splitter 3, signal transmission/reception antennas 4, merit to divide amplifier 5, power splitter 6, filter 7, demodulator 8, decoder 9, transmitter 10, transmitting antenna 11, reception antenna 12, receiver 13, modulator 14, emission upconverter 15 and local oscillator 16; Described reception antenna 12 receives user's microwave alarm signal, and by receiver 13, modulator 14, emission upconverter 15, local oscillator 16 and UPC signal processor 17 mail to central station with alarm signal from signal transmission/reception antennas 4; Described UPC signal processing 17 and local oscillator 16 are the alarm signal load instructions and produce microwave signal; Described merit is divided amplifier 2, power splitter 3, merit to divide amplifier 5, power splitter 6 to form two-way emission driving source merit and is divided amplifier; Wherein input IN is connected with antenna 1, input again with by T
1, T
2, T
3The merit of forming divides amplifier 2 inputs to be connected, and merit divides amplifier 2 outputs to be connected the output termination antenna 4 of power splitter 3 with an end of power splitter 3; Another termination of power splitter 3 is by triode T
4, T
5, T
6Another merit of forming is divided amplifier 5, and this merit is divided an input of another power splitter 6 of output termination of amplifier 5, and an end of described power splitter 6 connects antenna 1 by filter, and the other end connects antenna 11 by demodulator 8, decoder 9 and transmitter 10
The utility model can transmit two-way signaling, comprises instruction and warning microwave signal that central station sends, also can transmit wide band television image simultaneously.
The drawing explanation:
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is that the two-way emission driving source merit of position of the present utility model mark communication device divides amplifier circuit to implement illustration.
The antenna 1 of mark communication apparatus in position provided by the utility model can receive the control command that station signal or launching centre station are transmitted.Divide amplifier 2, power splitter 3 and antenna 4 that last station signal is sent to central station by merit after receiving the station signal.The control command that is transmitted by the center is to be received by antenna 4, and divides amplifier 5, power splitter 6, filter 7 to mail to other station antenna 11 launching centre control commands by antenna 1 through merit and give each user, carry out and take precautions against action.After user's microwave alarm signal is received by antenna 12, by receiver 13. modulators 14, emission upconverter 15, merit divide amplifier 2, power splitter 3 to mail to central station through antenna 4, described system centre station is the both-way communication network terminal, comprising: downlink signaling (user's control command) produces circuit, electronic chart and customer database
