Embodiment:
Road sign is gathered the structure of detector and is seen Fig. 1～4,1st, highway section sign, the 2nd, Directional Sign.Both all make with metallic material, are installed in the centre of two rails 3.Can be fixed on the sleeper 4 with railway spike 5, also can be fixed on the rail 3 with screw 6 again.Highway section (or position) sign 1 is 13 two scale notation code characters, and Directional Sign 2 is one group 1010000000000 yards, also is 13 two scale notation code characters, but belongs to one of them specific code, can be reduced to 101 brachmorphy signs.Highway section sign 1 is used with Directional Sign 2, should place the brachmorphy sign high order end of microscler sign in use.Like this, the train of any direction running, by to the collection of long and short shape sign, handle the highway section that just can know self place exactly and the direction of travelling.In Fig. 4, because the turnout is shorter generally speaking, so length is disregarded.When highway section sign 1 and Directional Sign 2 are used, grow earlier afterwards to lack and represents to travel from left to right, otherwise first short and then long then.In each bar highway section, can add a special metal flag as 100 meters at a certain distance, form the tick lables of representing with 13 two scale notation code characters 1000000000000 (not drawing among the figure), train is by discerning and counting, cooperate the road segment number that recognizes again, just can understand data such as the present orientation of train (highway section and milimeter number), running velocity, direction and license number.Be example now with 1435 millimeters standard gauge, the inboard distance of locomotive wheel is 1353 ± 3 millimeters, according to left and right displacement sum in the train operation: passenger vehicle is 2～6 millimeters, lorry is 2～20 millimeters work bases, highway section sign 1 adopts 13 two scale notation code characters, if wherein every bit wide is 100 millimeters, then the outside, the first and last position of road sign code character is 25～28 millimeters apart from wheel, satisfies the requirement of displacement.For improving the reliability of gathering, " the " center " sampling allows every bit width of collector to be not more than 60 millimeters in employing.Like this, remove in the sign of 13 highway sections that Directional Sign 1010000000000 and tick lables 1000000000000 are outer still surpluss 8190 road segment numbers and use for the highway section.In Fig. 4, the 7th, operating train.
Fig. 5～6th, the workflow scheme drawing of the method that the present invention proposes.
Goodbye Fig. 7.The 8th, road sign is gathered detector, the 9th, shaping amplifier, the 10th, the transmitting terminal terminating machine of Vehicle mounted station, the 11st, the emitter of Vehicle mounted station, the 12nd, emission or receiving wire, the 13rd, the automatic switching control circuit of receiver receiving cable power supply and transmitter supply, the 14th, the receiver of Vehicle mounted station, the 15th, demoder, the 16th, the receiving end terminating machine of Vehicle mounted station, the 17th, display circuit, the 18th, be contained in the microprocessor on the platform, what link to each other with the latter 14 and 11 is respectively that wireless data on the platform receives and emitter.Above-mentioned terminating machine, microprocessor all use chip 8031 or 80C31 to constitute, and its interconnected relationship is as above-mentioned.Be sent to transmitting terminal terminating machine 10 again after road segment number, service direction and the Train Dynamic location parameter that road sign collector 8 is gathered transported to shaping amplifier 9, it is to vehicle-mounted emitter 11 output pocsag codes and through wireless data receiver 14 and the local operational factor that just at operating other trains send this train of antenna 12 on the station.Meanwhile, start the automatic switching control circuit 13 of receiver receiving cable power supply and transmitter supply, make the dynamical parameter of other running trains that vehicle-mounted receiver 14 is received through just being sent to the receiving end terminating machine 16 of Vehicle mounted station behind the demoder 15, it is sent to display circuit 17 to computational data again.The incoming signal of the microprocessor 18 on the station is from the wireless data receiver 14 on the station that is used to receive each train runing parameters, it just sends to other operating trains by wireless data transmitter on the station 11 and antenna 12 after its data of receiving are handled, and shows AT STATION.
Evidence: but the method that the present invention proposes reaches the relative motion relation that detects to the designed system real-time continuous train runing parameters according to this and provide this train and local other trains, to guarantee the safe operation of train.
