Compared with the prior art, utilization of the present invention be that existing cellular wireless mobile communication net is located automatically, no matter be the cost of manufacture of locating device, or use cost, all reduce any people or MOVING STRUCTURE (as automobile, steamer etc.) zone of living in that can carry locating device per capita significantly by the cell communication network inquiry.It is low to have cost of manufacture, and use cost is low, easy to use, and good practical effect is easy to popularize the characteristics of using.Can be used for the zonule of personnel at all levels, MOVING STRUCTURE is located automatically.
Below in conjunction with accompanying drawing the specific embodiment of the present invention is done and to be described in further detail.
Fig. 1 is the circuit structure block diagram of control section of the present invention.
Embodiment: radio positioner comprises power supply, housing, antenna and control section.Control section comprises: the radio-frequency (RF) switch that can receive device for searching signal and emitting radio frequency signal 1 that is connected with antenna; The radio frequency of received RF switch 1 output seek signal and to its amplify, the radio frequency amplification filtering circuit 2 of Filtering Processing; The reference frequency output signal that the radio frequency searching signal of received RF filter amplification circuit 2 outputs and voltage controlled oscillator 3 are provided, and utilize reference frequency signal that radio frequency is sought the frequency mixer 4 that signal carries out down conversion process; The intermediate frequency through frequency reducing of receiving mixer 4 output is sought signal, and to its amplify, the intermediate frequency processor 5 of filtering; The intermediate frequency that receives intermediate frequency processor 5 outputs is sought signal, and is converted into the modulator-demodular unit 6 that corresponding numeral is sought signal; Numeral to modulator-demodular unit 6 outputs is sought single machine unit 7, the SIM card 8 that signal is discerned, controls, handled; Receive the intermediate frequency back-signalling of single-chip microcomputer 7, and be converted into the frequency synthesizer 9 of medium standard frequency back-signalling through modulator-demodular unit 6 outputs; The medium standard frequency signal of receive frequency compositor 9 output, and it is carried out frequency conversion process, it is transformed to the emission voltage controlled oscillator 10 of corresponding radio frequency back-signalling; Receive the radiofrequency signal of emission voltage controlled oscillator 10 outputs and it is carried out the pre-exciting circuit 11 that amplifies of power; Receive the radio frequency back-signalling of exciting circuit 11 outputs and the power control signal of received power controller 12 outputs, can produce the rf power amplifier 13 of varying strength radio frequency back-signalling, wherein the input end of power controller 12 and radio-frequency (RF) switch 1 are joined, the corresponding power control signal of intensity output of the device for searching signal that receives according to radio-frequency (RF) switch 1; The radio frequency back-signalling for emission usefulness of rf power amplifier 13 outputs is connected to radio-frequency (RF) switch 1.
This device in use, on one's body the user is carried at device, when the inquiry need understand carrier's position, send the device for searching signal by cellular mobile communications networks, seek signal after the receiving circuit of the radio-frequency (RF) switch 1 of device receives, after amplification, filtering, mixing, obtain corresponding intermediate frequency again and seek signal, this intermediate frequency is sought signal and is given single machine unit 7 through the numeral searching signal that modulator-demodular unit 6 converts correspondence to, and single-chip microcomputer is sought the identification code of being deposited in device identification code contained in the signal and the SIM card 8 with numeral and compared affirmation.Once affirmation, single-chip microcomputer sends the response digital signal, convert corresponding intermediate frequency back-signalling to through modulator-demodular unit 6, be converted to the medium standard frequency back-signalling through frequency synthesizer 9 again, this intermediate frequency back-signalling is converted into radiofrequency signal again, after amplifying, (it is strong to seek signal, and then back-signalling weakens according to the power of the radio frequency back-signalling of strength control rf power amplifier 13 outputs of seeking signal from radio-frequency (RF) switch 1 detected radio frequency by power controller 12; A little less than the searching signal, then back-signalling is strengthened), the radio frequency back-signalling of rf power amplifier 13 output is sent to the cellular mobile communication base station through the radiating circuit of radio-frequency (RF) switch 1, the control center of cellular mobile communications networks according to base station coverage area to the residing zone of inquiry's annunciator carrier.
