Description
Technical field
The invention belongs to railroad track detection technique field, be specifically related to a kind of mileage measurement mechanism based on Hall switch.
Background technology
Rail is most important infrastructure in transportation by railroad.Because rail is chronically exposed in severe physical environment, and continuous bearing load, rail surface state constantly changes, and may produce damage or distortion, and even occur sleeper cracking, railway spike comes off etc. has a strong impact on the situation of train traffic safety.For guarantee driving safety, must detect the state of rail, prevent rail from occurring unusual condition, cause driving accident.
Traditional artificial visual inspection can not adaption demand, mainly takes the mode of track checking car to detect railroad track health status at present.This method adopts computer technology, can produce a large amount of data, therefore need to position fault data.The mode of current employing is GPS location, but GPS location is subject to the restriction of environmental factor, and positioning precision is lower, particularly substantially loses efficacy in tunnel, therefore needs to take other auxiliary equipment.
Utilize mileage to take turns, can measure by it mileage that track checking car advances, and then abort situation is accurately located.Current mileage wheel is general adopts honeywell switch sensor technology (Chinese patent: CN200610025468.1), runner is installed multiple permanent magnet, when mileage wheel rotates, permanent magnet can trigger through Hall switch and once count, and calculates the number of turns that runner turns over and is multiplied by girth and just obtains mileage of walking.But this mode can not realize direct of travel to be distinguished, precision is not high enough simultaneously, and needs integral replacing when runner wearing and tearing can not work, and reinstalls permanent magnet.
Summary of the invention
The technical issues that need to address of the present invention are that existing mileage measurement mechanism positioning precision is low, and can not distinguish direct of travel.
A kind of mileage measurement mechanism based on Hall switch of the present invention, comprise: runner, lifting magnet, stationary shaft, permanent magnet, Hall switch, treatment circuit and support, it is characterized in that: runner is fixed between the two-arm of support, and can along being parallel to support two-arm direction Free-rolling; Between the two-arm of support, described runner both sides are also respectively equipped with a circular magnet dish, are provided with a circular depressed along lifting magnet circumferencial direction, and permanent magnet is evenly installed in circular depressed, and the permanent magnet distribution of runner both sides lifting magnet is identical; The two-arm of support is respectively equipped with Hall switch, and on support, the position of Hall switch is corresponding by the permanent magnet position of support institute cover part with lifting magnet; Hall switch is connected with treatment circuit by wire, realizes power supply and Signal transmissions.
Preferably, in the two-arm of described support, every side is provided with two Hall switch, the common circumference of the projection of Hall switch in space of both sides, and symmetrical relative to runner, and the angular distance between homonymy two Hall switch is 22 °.
Preferably, the permanent magnet quantity on the lifting magnet of every side is 45, the common circumference of the both sides projection of all permanent magnets in space, and the angular distance between two permanent magnets that homonymy is adjacent is 8 °.
Preferably, the permanent magnet on the lifting magnet of side and the permanent magnet on offside lifting magnet the minor increment be total to circumferentially be 3 °.
Preferably, be also provided with circuit box between the two-arm of described support, described treatment circuit is installed among circuit box.
Beneficial effect of the present invention is:
A kind of mileage measurement mechanism based on Hall switch of the present invention, realized segmentation and the measurement of the runner anglec of rotation by reasonable Arrangement Hall switch and permanent magnet, resolution is high, and simultaneously can realize direction of motion distinguishes, error count when preventing counter motion.By being separated of runner and lifting magnet, when runner weares and teares, can change separately, avoid permanent magnet again to reinstall and complicated debugging.
