The specific embodiment:
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described.Obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
It is that train position detection is realized on the basis that the present invention adopts radio frequency discrimination RFID equipment, it should be noted that the occupation mode of radio frequency discrimination RFID among the present invention and the mode of generally having understood at present (described in [R1 opinion rail transit train location detecting apparatus]) are diverse.
The common method of using radio frequency discrimination RFID to do position probing is that miles counter and radio frequency discrimination RFID reader are installed ON TRAINS, radio frequency identification (RFID) labels is installed on ground, car-mounted computer is determined the position at label place according to the radio frequency identification (RFID) labels that reads, according to the position between miles counter and the electronic chart calculating label.
Method of inspection of the present invention is in the track both sides reader and label to be installed respectively, head and afterbody at train are installed beacon, when train does not arrive the detection position, reader can read the beacon of track opposite side, when train arrives the detection position, because the blocking-up reader of train can not read the label of track opposite side, but at this moment reader can read the label on the train, realize by this method the detection of train single-point position, simultaneously can by reading the label of train head and afterbody, judge the service direction of train.Based on the detection for train single-point position and current of traffic, can further realize the detection of train section position.
Fig. 1 is the schematic diagram of train single-point position probing, and whole checking system is made of radio frequency discrimination RFID reader, trackside beacon, train detection unit and vehicle-mounted beacon as shown in the figure.
The detection principle of train single-point position is: when train does not arrive the detection position, reader can read the trackside beacon, when train arrives the detection position, because the blocking-up reader of train can not read rail trackside beacon, the train detection unit can judge that train " arrives/do not arrive " detection position according to trackside beacon " reading/do not read ".
So following Fig. 2, no matter be the fault of trackside beacon, reader and communication link, all only can cause to read the trackside beacon, thereby the train detection unit can be judged train and be " arrival " detection position state, this is a safe condition for signal system, so train position detection method of the present invention has fail-safe feature.
