The flow chart of the detection method of a kind of transponder transport module that Fig. 1 provides for the embodiment of the invention, the method can comprise the steps:
Whether step 101, the described transponder transport module of detection are in idle condition; If be in idle condition, then change step 102 over to; Otherwise change step 103 over to.Whether this step is receiving the message that ground transponder sends for detection of the transponder transport module.
Step 102, periodicity send and receive loop operating state detection messages to described transponder transport module.When the transponder transport module is in idle condition, then detection messages periodically is sent to the transponder transport module.
Step 103, time-delay send.When the 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 this transponder transport module when being in idle condition, sends and receives loop operating state detection messages again.
Step 104, according to the reception loop work state information of the described transponder transport module feedback that receives, obtain the work at present state information of transponder transport module.In real work, after receiving this detection messages, the transponder transport module can carry out according to the content of message the feedback of corresponding information, and according to this transponder transport module feedback information that receives, can obtain the work at present state information of transponder transport module.
The embodiment of the invention detected the idle condition of transponder transport module in advance before sending detection messages, when the transponder transport module is idle, then periodically send detection messages to the transponder transport module, otherwise time-delay sends, realized in the situation that does not affect the normal operation of transponder transport module, it is carried out the detection of operating state, guaranteed that the transponder transport module can receive the information that ground transponder sends accurately, for traffic safety provides guarantee.
Embodiment two
In order to introduce more specifically the present invention, 2 couples of the present invention are described further below in conjunction with accompanying drawing, can may further comprise the steps:
Step 201, the signal strength detection of when the transponder transport module starts, carrying out, and periodic strength of transmitted signals detection messages.Described transponder transport module is in case start, then continual transmission is used for activating the signal (for example signal of 27M signal strength signal intensity) of ground transponder, if the signal strength signal intensity that the transponder transport module sends is lower, then will cause with the data interaction of ground transponder imperfect, even can't activate ground transponder, therefore, need to the signal strength signal intensity of transponder transport module be detected, for example pass through the 27M signal strength signal intensity of the A1 interface of detection transponder transport module, and periodic strength of transmitted signals detection messages.
Step 202, according to the signal strength signal intensity result of described transponder transport module feedback, judge whether the power amplifier of described transponder transport module and antenna work.If the signal strength signal intensity that the transponder transport module sends reaches its rated power (for example 27M), show that then the power amplifier of this transponder transport module and antenna are working properly, otherwise break down.
Whether step 203, the described transponder transport module of detection are in idle condition; If be in idle condition, then change step 204 over to; Otherwise change step 205 over to.Whether this step is receiving the message that ground transponder sends for detection of the transponder transport module.For example, can judge whether the transponder transport module is receiving the message that ground transponder sends by the fsk signal that detects transponder transport module A4 interface, its detecting step can be the reception sources signal, and source signal carried out impedance matching, so that the impedance phase of the impedance of source signal and load (for example band pass filter) coupling; Signal after the impedance matching is filtered the interference signal of the non-predeterminated frequency of filtering; And in order not affect the proper communication between transponder transport module and ground transponder, therefore, the signal that receives when detecting is less, causes the sensitivity of source signal lower, can't activate power-sensing circuit; Thereby need the signal after filtering is amplified processing, carry out again the detection of watt level.If the intensity of described power detection surpasses some strength (corresponding transponder minimum emissive power), then source signal is fsk signal, and this moment, the transponder transport module was just communicated by letter with ground transponder; Otherwise be in idle condition.
