Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection scope of the present invention.
Embodiment one
The flow chart of the detection method of a kind of transponder transport module that Fig. 1 provides for the embodiment of the present invention, the method can comprise the steps:
Step 101, detect described transponder transport module and whether be in idle condition; If be in idle condition, then proceed to step 102; Otherwise proceed to step 103.Whether this step is receiving the message of ground transponder transmission for detecting transponder transport module.
Step 102, periodically transmission and reception loop work state-detection message are to described transponder transport module.When transponder transport module is in idle condition, then detection messages is periodically sent to transponder transport module.
Step 103, time delay send.When transponder transport module is just receiving the message of ground transponder transmission, for not affecting the proper communication between transponder transport module and ground transponder, then time delay sends detection messages, until when this transponder transport module is in idle condition, then transmission and reception loop work state-detection message.
Step 104, the reception loop work state information fed back according to the described transponder transport module received, obtain the current operating state information of transponder transport module.In real work, the feedback of corresponding information can be carried out according to the content of message after transponder transport module receives this detection messages, and according to this transponder transport module feedback information received, the current operating state information of transponder transport module can be obtained.
The embodiment of the present invention detected the idle condition of transponder transport module in advance before sending detection messages, detection messages is then periodically sent to transponder transport module when transponder transport module is idle, otherwise time delay sends, achieve when not affecting transponder transport module and normally working, it is carried out to the detection of operating state, ensure that transponder transport module can receive the information of ground transponder transmission accurately, for traffic safety provides guarantee.
Embodiment two
In order to introduce the present invention more specifically, below in conjunction with accompanying drawing, 2 couples of the present invention are described further, and can comprise the following steps:
Step 201, carry out signal strength detection when transponder transport module starts, and periodic strength of transmitted signals detection messages.Described transponder transport module is once start, then continual transmission is for activating the signal (such as the signal of 27M signal strength signal intensity) of ground transponder, if the signal strength signal intensity that transponder transport module sends is lower, then by imperfect for the data interaction caused with ground transponder, even ground transponder cannot be activated, therefore, need to detect the signal strength signal intensity of transponder transport module, such as by detecting the 27M signal strength signal intensity of the A1 interface of transponder transport module, and periodic strength of transmitted signals detection messages.
Step 202, the signal strength signal intensity result fed back according to described transponder transport module, judge whether the power amplifier of described transponder transport module and antenna normally work.If the signal strength signal intensity that transponder transport module sends reaches its rated power (such as 27M), then show the power amplifier of this transponder transport module and Antenna Operation normal, otherwise break down.
Step 203, detect described transponder transport module and whether be in idle condition; If be in idle condition, then proceed to step 204; Otherwise proceed to step 205.Whether this step is receiving the message of ground transponder transmission for detecting transponder transport module.Such as, fsk signal by detecting transponder transport module A4 interface judges whether transponder transport module is receiving the message of ground transponder transmission, its detecting step can be: receive source signal, and impedance matching is carried out to source signal, make the impedance of source signal and the matches impedances of load (such as band pass filter); Signal after impedance matching is filtered, the interference signal of the non-predeterminated frequency of filtering; And in order to not affect the proper communication between transponder transport module and ground transponder, therefore, the signal received when detecting is less, causes the sensitivity of source signal lower, cannot power-sensing circuit be activated; Thus need the signal after to filtration to carry out amplification process, then carry out the detection of watt level.If the intensity of described power detection exceedes some strength (corresponding transponder minimum emissive power), then source signal is fsk signal, and now transponder transport module just communicates with ground transponder; Otherwise be in idle condition.
Step 204, periodically transmission and reception loop work state-detection message are to described transponder transport module.When transponder transport module is in idle condition (without fsk signal), then detection messages is periodically sent to transponder transport module.Described reception loop work state comprises: the operating state of the inner members such as reception antenna, reception amplifier, demodulator circuit and decoding circuit.This detection messages can be that agreement meets transponder transport module message specification and has the message of special sign in advance, or the loop coding of other type, as m sequence, M sequence, Walsh coding etc.
Preferably, for ensureing that detection messages can normally be sent to transponder transport module, loop work state-detection message can be sent to described transponder transport module after power amplification.
Step 205, time delay send.When transponder transport module and ground transponder carry out (fsk signal of transponder transport module A4 interface being detected) when normal message is transmitted, for not affecting the proper communication between transponder transport module and ground transponder, then time delay sends detection messages, until this transponder transport module is in time delay time T(such as 500mS after idle condition) transmission and reception loop work state-detection message, have influence on transponder message after avoiding detection messages to follow transponder message closely and normally receive.
Step 206, the reception loop work state information fed back according to the described transponder transport module received, obtain the current operating state information of transponder transport module.After transponder transport module receives this detection messages, carry out the feedback of corresponding information according to the content of message, then according to the feedback information received, obtain the current operating state information of transponder transport module.
The embodiment of the present invention carries out periodic signal strength detection to transponder transport module, ensure that the intensity of transponder transport module transmission signal reaches rated power, to ensure its energy normal Activate ground transponder; And before sending detection messages, detect the idle condition of transponder transport module in advance, detection messages is then periodically sent to transponder transport module when transponder transport module is idle, otherwise time delay sends, achieve when not affecting transponder transport module and normally working, it is carried out to the detection of operating state, ensure that transponder transport module can receive the information of ground transponder transmission accurately, for traffic safety provides guarantee.And the detection messages sent is with transponder message format or other cyclic code, the simultaneous verification receiving circuit of transponder transport module and the operating state of demodulating and decoding module.
