Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Shown in Fig. 1-4.
A kind of airborne collision avoidance system (being called for short TCAS) simulator unifrequency is derived from detecting method, an inquiry module and a responder module that only produces the 1090MHz frequency that only produces the 1030MHz frequency is set at first respectively, coupler with make the inquiry module and self check source each other after responder module is connected by coupler and radio frequency cable, thereby reach in the inquiry module and save 1 1090MHz frequency source, in responder module, save 1 1030MHz frequency source, simplify the purpose of self-checking circuit.Wherein said self-checking circuit block diagram as shown in Figure 1, and the structure of airborne collision avoidance system simulator is referring to Fig. 4.Can find out that by Fig. 1,4 circuit of TCAS simulator is made up of two parts, be respectively inquiry module section and responder module part.
The circuit of inquiry module and responder module is worked in coordination and is realized the self-checking function of simulator.When self check, the signal processor of inquiry module produces self check pulse train, after modulators modulate, obtain the radiofrequency signal of 1030MHz, from this 1030MHz radiofrequency signal, be coupled out 1 the road to the SMA type socket of inquiry module front panel by a coupler again.This road 1030MHz modulation signal that is coupled out is sent to responder module by 1 radio frequency cable, and as the self check source of responder module, this self check source signal enters the receive path of responder module, and the responder module receive path is tested.The vision signal that the receive path of responder module obtains processing is sent the signal processor of responder module; After the signal processor of responder module is discerned interrogation mode, with the interrogation mode of the interrogation mode that identifies and setting relatively,,, then quote the information of responder module fault if inconsistent if both unanimities are just quoted the normal information of responder module.
The self check pulse train (the C pattern is generally called interrogation mode) that Fig. 2 produces for inquiry module by signal processor, when the interrogation mode that the responder module signal processor identifies was consistent with pattern shown in Figure 2, responder module was normal.
In the responder module self check, the signal processor of responder module produces self check pulse train, after modulators modulate, obtains the radiofrequency signal of 1090MHz, from this radiofrequency signal, be coupled out 1 the tunnel by a coupler, deliver on the SMA type socket of responder module front panel.The radio signal transmission of the 1090MHz that responder module is sent by a radio frequency cable is to the SMA type socket of inquiring the module front panel, as the self check source of inquiry module then.This self check source signal enters the receive path of inquiry module, handles out the signal processor that vision signal is sent the inquiry module by the receive path of inquiry module; The signal processor of inquiry module is handled this vision signal and is decoded, and the answer back code that obtains is compared with the answer back code of setting, if both unanimities are just quoted the normal information of inquiry module, if inconsistent, then quotes the information of inquiring module failure.
The self check pulse train (the A code is 7607) that Fig. 3 produces for the responder module signal processor, the A code that inquiry module by signal processor decodes obtains is 7607 o'clock, the inquiry module is normal.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
