Photoelectric sensor no. 1 and photoelectric sensor no. 2 be along with the vehicle removes, when passing through the check point, can acquire the detected signal according to luminosity changes at every turn, because the check point fixes, and the consequently quantity of the detected signal that acquires of basis, 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 no. 1 and two conduct measuring tool of photoelectric sensor obtain absolute position information.
Description
Technical field
The utility model belongs to sensor technical field, particularly a kind of guideway vehicle registration device based on dual sensor Photoelectric Detection.
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 based on dual sensor Photoelectric Detection, 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 a guideway vehicle registration device for dual sensor Photoelectric Detection, comprising:
Be installed on the opto-electronic pickup one bottom guideway vehicle and opto-electronic pickup two, along guideway vehicle working direction, opto-electronic pickup one is positioned at the dead ahead of opto-electronic pickup two;
Be set in turn in the multiple check points on track along guideway vehicle working direction, the distance between adjacent check point is greater than the spacing of opto-electronic pickup one and opto-electronic pickup two;
And the microprocessor to be connected with opto-electronic pickup one and opto-electronic pickup two.
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 based on dual sensor Photoelectric Detection, comprising:
Be set in turn in the multiple check points on track along guideway vehicle working direction, check point can directly use tie or fixture of the rail, has comparatively fixing interval.
Be installed on the opto-electronic pickup one bottom guideway vehicle and opto-electronic pickup two, along guideway vehicle working direction, opto-electronic pickup one is positioned at the dead ahead of opto-electronic pickup two, carries out induction detect check point.Distance y between adjacent check point is greater than the spacing x of opto-electronic pickup one and opto-electronic pickup two;
The microprocessor be connected with opto-electronic pickup one and opto-electronic pickup two, the information that microprocessor can obtain opto-electronic pickup one and opto-electronic pickup two carries out the basic process such as collecting, 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:
Opto-electronic pickup one and opto-electronic pickup two move 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 ", opto-electronic pickup one and opto-electronic pickup two are 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.
