Described communication module 15 is electrical connected with processing module 12.In the present embodiment, link to each other with the train dispatching center by wireless transceiver 151, be used for transmission fault information.After detecting the trouble spot, processing module 12 is sent to the train dispatching center by wireless transceiver 151 with failure message.Scheduling by the train dispatching center makes not carrying of train to be measured, and directly drives towards the maintenance field, to do further inspection.
Referring to Fig. 2, a kind of train failure detector of the utility model workflow schematic diagram.
Init state: when the train headstock of normal operating conditions crosses infrared facility 131, infrared receiver 1312 does not receive the infrared signal that infrared transmitting device 1311 is launched, trigger the timer 122 beginning timing in the processing module 12, the microphone 111 that triggers simultaneously in the frequency spectrum detection module 11 converts voice signal to electric signal in real time, and transfers to processing module 12.The amplitude variable of the electric signal that detects is analyzed and recorded to single-chip microcomputer 121 in the processing module 12, with this initial value as voice signal (or claiming reference value).With this initial value (or claim reference value) and detect the time of this signal that time and be stored in the storer 122.When the train tailstock leaves infrared facility 131, infrared receiver 1312 receives infrared signal, and to processing module 12 transmitted signals, so that the timer 122 in the processing module 12 is recorded the moment a of this moment, stop simultaneously spectrum analysis (referring to shown in Figure 3).
Continuation is referring to Fig. 2, device installs also and enters duty after the initialization: when train headstock to be measured crosses infrared facility 131, infrared receiver 1312 does not receive the infrared signal that infrared transmitting device 1311 is launched, trigger the timer 122 beginning timing in the processing module 12, the microphone 111 that triggers simultaneously in the frequency spectrum detection module 11 converts voice signal to electric signal in real time, and is transferred to processing module 12.The amplitude variable of the electric signal that detects is analyzed and recorded to single-chip microcomputer 121 in the processing module 12, with this instantaneous value as voice signal.Single-chip microcomputer 121 compares the initial value of storage in the storer 123 in the instantaneous value that obtains and the processing module 12.If instantaneous value is different from initial value, the timer 122 that then triggers in the processing module 12 recorded at that time constantly f(fault moment), proofread and correct by triggering correcting unit 124 again (concrete bearing calibration and principle have description later), if still be judged as fault after proofreading and correct, then the hummer 141 in the trigger alarm module 14 sounds the alarm.When the train tailstock to be measured leaves infrared facility 131, infrared receiver 1312 receives infrared signal, and to processing module 12 transmitted signals, so that the timer 122 in the processing module 12 is recorded the time of the passing through b of this train, and empty the value of fault moment f in the timer 122.Stop simultaneously spectrum analysis.Trigger simultaneously charactron 142 and show that the trouble spot is from the ratio of headstock horizontal range d and length of wagon s.
Fault detection status: processing module 12 can utilize the time of passing through of fault moment, whole train to be measured and the vehicle commander of train to calculate the trouble spot from the horizontal range of train headstock, and this distance is presented on the charactron 142 in the alarm module 14.Trigger simultaneously communication module 15 and start working, failure message is transferred to the train dispatching center by wireless transceiver 151, make this be listed as train to be measured and directly drive towards the maintenance field, to do further fault detect.
Calculate the trouble spot from the algorithm of the horizontal range of train headstock by processing module 12, specific as follows:
Obtain train by time b by the timer in the processing module 12; And the moment f of trouble spot appearance.Because the hypothesis train is uniform motion, thus the moment f that breaks down with approximate the trouble spot from the ratio of headstock horizontal range d and length of wagon s by the ratio k of train by time b.After train enters the parking lot, be easy to just can know the length of wagon s of train, thereby draw d=k*s.The convenient for maintaining personnel discharge fault fast further.
Concrete bearing calibration and principle are as follows: when amplitude variable and the initial value (or claiming reference value) of the electric signal that detects train to be measured not simultaneously, namely breaking down constantly, f(is not equal to zero), then can adopt bearing calibration again to judge.Because this device adopts all trains to be measured every days to compare by frequency spectrum data and the reference amplitude variable that fixed time measures when detecting website, and the situation that train to be measured exists (by detecting website) detection constantly to change in actual moving process, for example train is overdue, if still gather frequency spectrum data by the fixed time that presets every day, the line frequency of going forward side by side spectrum data relatively, then can cause when reality detects frequency spectrum data, the parameters of detection time that process detects the same row train to be measured of website is not to be the parameters of detection time that presets, thereby produces deviation.Therefore need to solve by bearing calibration.Solution plan is manually to send correction instruction to described correcting unit by computer program or train scheduling chamber yardman, arrive at a station late and interference (environmental factor mainly refers to the near-earth noise) environmental factor to judge again whether train to be measured exists, if then adjust the parameters of detection time of train to be measured by described correcting unit.Pressed from 0 o'clock to 24 o'clock every day is all trains numberings to be measured through this order that detects website successively, make the same day consistent with the numbering of the train to be measured that presets through the train to be measured of this detection website, thereby the actual parameters of detection time of train to be measured that makes same numbering is with to preset parameters of detection time corresponding.Can get rid of easily the disturbing factor of testing conditions by described correcting unit, and then more effectively detect train to be measured and whether have fault.
By described train failure detector, can be both accurate, record rapidly again the trouble spot of train, accuracy of detection is high.And simple to operate, whole detection is all finished by single-chip microcomputer with the location.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model structure; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
