The specific embodiment
For those skilled in the art can understand technical scheme provided by the present invention better, set forth below in conjunction with specific embodiment.
See also Fig. 1-Fig. 3, Fig. 1 is the safety detection device installation structural representation in orbit that in the embodiment of the present invention, motorcycle axle is counted and tested the speed; Fig. 2 is the safety detection device installation cross section structure schematic diagram in orbit that in the embodiment of the present invention, motorcycle axle is counted and tested the speed; Fig. 3 is the constitution diagram whether signal such as vehicle parking is arranged in interval to be detected in judgement in motorcycle axle counting and the safety detection device that tests the speed in the embodiment of the present invention.
The motorcycle axle counting that the present embodiment provides and the safety detection device that tests the speed, comprise first sensor 1, the second sensor 2, mounting bracket 5, signal adapter 3 and track card 4, first sensor 1 and the second sensor 2 are respectively edd current transducer, first sensor 1 is installed and is connected with signal adapter 3 respectively along track 6 length directions with the second sensor 2, signal adapter 3 is connected with the data processing unit of system, signal adapter 3 is arranged on track card 4, and track card 4 is connected to the bottom of track 6.
Track card 4 comprises the first deck 41, the second deck 42 and binding bolt 43, the first deck 41 and the second deck 42 are respectively arranged with the groove of clamping rail 6 bottoms, road, the first deck 41 and the second deck 42 are clamped on track 6 bottoms by binding bolt 43, during installation, the bottom that only the first deck 41 and second deck 41 of track card 4 need be connected to track 6, then get final product by binding bolt 43 lockings, install simple and convenient.
The principle of work of the motorcycle axle counting that the present embodiment provides and the safety detection device that tests the speed is as follows:
Because first sensor 1 and the second sensor 2 are all edd current transducers, when ferromagnetic material being arranged through out-of-date, its built-in field can change, thereby affect the voltage swing of its output, namely when being in high level state without ferromagnetic material through out-of-date these two sensors, when have ferromagnetic material (as motorcycle axle) above it in 0-50mm through out-of-date, it is in low level state; When first sensor 1 and the second sensor 2 are installed in addition lower than orbit plane, according to the China railways technical stipulation, first sensor 1 and the second sensor 2 are processed in safe range apart from the distance of raceway surface, easy for installation, need not track or railway roadbed are done any change, can not affect normal locomotive operation.
Compared with prior art, motorcycle axle counting provided by the invention and the safety detection device that tests the speed, simple in structure, easy for installation, powerful, and low price, have following five functions: 1, system triggers is opened; 2, train meter shaft; 3, axletree tests the speed; 4, whether judgement has the signals such as vehicle parking in interval to be detected; 5, two-way detection.
1, system triggers detects
the triggering open function principle of system is as follows, on track before safety detection device is arranged on existing motorcycle safety check implement, when without locomotive process sensor top, first sensor 1 and the second sensor 2 are in all high level states " 1 ", when have an axletree the direction of first sensor 1 to second sensor 2 through this device above the time, " 11 → 01 → 00 → 10 → 11 " time sequence status can appear in the level of two sensors of this device, after safety detection device is received a complete sequential, the motorcycle safety detecting device is powered on, whole checking system is in the state to be detected that powers on.
2, the locomotive meter shaft detects
when without locomotive during through first sensor 1 and the second sensor 2 top, first sensor 1 and the second sensor 2 are in all high level states " 1 ", when have an axletree the direction of first sensor 1 to second sensor 2 through this safety detection device above the time, " 11 → 01 → 00 → 10 → 11 " time sequence status can appear in the level of two sensors of this safety detection device, be that safety detection device thinks that a complete axletree enters detection zone when complete " 11 → 01 → 00 → 10 → a 11 " sequential being detected, when this safety detection device of locomotive process, system can pass through to detect " 11 → 01 → 00 → 10 → 11 " thereby the number of sequential judges the number of axletree, the number that is axletree is consistent with the number of complete " 11 → 01 → 00 → 10 → 11 " sequential of appearance, system realizes the meter shaft function by this detection principle.
3, axletree tests the speed
Safety detection device when mounted, the range information of manual measurement first sensor 1 and the second sensor 2 in advance, this specifying information namely immobilizes after this device is installed in orbit.Whole checking system collecting unit can calculate successively collects first sensor 1 corresponding to axletree and the time gap of the second sensor 2 low level signals, thereby obtains axletree through the temporal information of this safety detection device.Utilize above-mentioned range information and time information can calculate the speed of axletree.Systematic collection can obtain the average velociity of this locomotive after the speed of all axletrees of a row locomotive.
4, whether judgement has the signals such as vehicle parking in interval to be detected
In track 6 two ends one segment distance scopes, a safety detection device is installed respectively in advance, can be utilized these two safety detection devices to judge the signals such as whether vehicle parking is arranged in this testing distance scope, concrete principle is as follows:
As shown in Figure 3, when locomotive travels along safety detection device S 1 to safety detection device S2, during sequential number that the number of the sequential " 11 → 01 → 00 → 10 → 11 " that detects as safety detection device S1 detects more than safety detection device S2, explanation has the axletree of locomotive to exist between safety detection device S1 and safety detection device S2, and after this situation surpassed a period of time, can illustrate in safety detection device S1 and safety detection device S2 interval to have locomotive to be in dead ship condition.
5, two-way detection
No matter locomotive is from which direction during through detecting device, systematic collection to sequential be all " 11 → 01 → 00 → 10 → 11 ", simultaneously can judge according to the low level time sequence that first sensor 1 and the second sensor 2 are collected the direction of car, even first sensor 1 receives that first it is from sensor 1 to second sensor 2 that low level is crossed the car direction, otherwise the locomotive operation direction is from the second sensor 2 to first sensor 1.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from the spirit or scope of the present invention, realization in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
