Abstract
Install in the three or three above photoelectric sensor of rail vehicle bottom, each photoelectric sensor lines up a straight line parallel with the rail vehicle direction of advance, and the interval between the adjacent photoelectric sensor is x, following the rail vehicle direction of advance and setting gradually a plurality of check points on the track, the distance between the adjacent check point is y, x < y, and with the microprocessor that each photoelectric sensor connects. Each photoelectric sensor is along with the vehicle removes, when passing through the check point, can acquire the detected signal according to the luminosity change at every turn, because the check point fixes, and consequently according to the quantity of the detected signal that acquires, the quantity of the check point that can obtain passing through to obtaining the locating information, promptly, regarding as the check point " electronic map ", photoelectric sensor obtains absolute position information as measuring tool.
Description
Technical field
The utility model belongs to sensor technical field, particularly a kind of guideway vehicle registration device detected based on multi-sensor photoelectric.
Background technology
In modern railway transportation traffic safety and command echelon, guideway vehicle location technology is a gordian technique, the important leverage be train safe, effectively running, has important effect in many-sides such as train automatic protection (ATP), automatic train operation (ATO), train automatic monitorings (ATS).
At present, the location technology that guideway vehicle is conventional has track circuit location, speed-position detection, beacon response location, satellite positioning, wireless frequency expansion location etc.Wherein track circuit positioning instant can realize location and can detect track fine status again, and cost is low, and shortcoming is location inaccuracy, cannot form movable block; Speed-position detection shortcoming there is accumulated error; The positioning precision that beacon is positioned at ground transponder attachment point is high, and shortcoming is that what to provide is point type locating information, there is the contradiction of setting space and scale of investment; The positioning precision of satellite positioning under state of kinematic motion lower than positioning precision under quiescence, the situation of station track that parallel line is easily admitted one's mistake, and be subject to the effect of natural conditions such as tunnel; The cost compare of wireless frequency expansion location is high.In practical application, consider the reliability of system, generally multiple location technology all can be adopted comprehensively to use, mutual redundancy, complement one another correction, makes the aspects such as the safety in track traffic and command echelon, survey precision, reliability, cost accomplish certain balance.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of guideway vehicle registration device detected based on multi-sensor photoelectric, is arranged on vehicle and uses, be different from existing guideway vehicle location technology completely.
To achieve these goals, the technical solution adopted in the utility model is:
Based on the guideway vehicle registration device that multi-sensor photoelectric detects, comprising:
Be installed on the opto-electronic pickup of more than three or three bottom guideway vehicle, each opto-electronic pickup lines up a straight line parallel with guideway vehicle working direction, and the spacing between adjacent photosensors is x;
Be set in turn in the multiple check points on track along guideway vehicle working direction, the distance between adjacent check point is y, x < y;
And the microprocessor to be connected with each opto-electronic pickup described.
Described check point is tie or fixture of the rail.
Described microprocessor connects car-mounted computer, and car-mounted computer shows testing result.
Compared with prior art, the beneficial effects of the utility model are:
1) guideway vehicle positioning device structure described in the utility model is simple, and low one-tenth is very low, only need install this device on existing guideway vehicle and get final product work, without the need at track a large amount of burial equipment along the line or set up base station etc.
2) guideway vehicle registration device positioning precision described in the utility model is high, has good resolution, and by detection calibration on track circuit in advance, then assisted by other location technology, error can be controlled in very little scope.If install this registration device respectively at headstock and the tailstock, the track particular location shared by vehicle and length can be learned.
3) guideway vehicle registration device easy maintenance described in the utility model, maintenance cost is extremely low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of guideway vehicle registration device detected based on multi-sensor photoelectric, comprising:
Be set in turn in the N number of check point on track along guideway vehicle working direction, check point can directly use tie or fixture of the rail, has fixing interval y.
Be installed on K opto-electronic pickup bottom guideway vehicle, K >=3, each opto-electronic pickup lines up a straight line parallel with guideway vehicle working direction, carries out induction detect check point; Spacing between adjacent photosensors is x.
The microprocessor be connected with each opto-electronic pickup, the information that microprocessor can obtain each opto-electronic pickup carries out the basic process such as collecting, and these process are without the need to relating to software protocol, and the function the most basic based on treater can realize.
And the car-mounted computer to be connected with microprocessor, car-mounted computer can count the information obtained, and namely obtains the relative positioning information of guideway vehicle, and shows testing result, according to the testing result of display.
Principle of the present utility model is:
Each opto-electronic pickup moves along with vehicle, each through check point time, detection signal can be got according to light varience, because check point is fixing, therefore according to the quantity of the detection signal obtained, the quantity of the check point passed through can be obtained, thus obtain locating information, that is, using check point as " electronic chart ", K opto-electronic pickup is as measuring tool.During normal operation, from certain website locomotive parking stall, namely start to carry out relative positioning counting, car-mounted computer, by " electronic chart " comparison with foundation, obtains absolute location information.
