Abstract
The utility model discloses a detecting point calibration instrument of an infrared detecting device, relating to the feild of an infrared detection. The detecting point calibration instrument of an infrared detecting device is used for the position calibration of the detecting point of the vehicles infrared hot box detector. The utility model is composed of a detecting point simulator and a signal receiving indicator. The simulator is an infrared radiation source capable of setting coordinate position randomly; the signal receiving indicator is composed of a direct-current power supply, a signal amplifier, a rectifier and an ammeter. The detecting point calibration instrument is directly bunched between a probe and infrared equipment at calibration time; when the probe is aligned to the detecting point, the ammeter displays the maximum, thereby, achieving the aim of calibration. The utility model has the advantages of simple structure, convenient operation, high detecting precision, etc.
Description
The utility model relates to a kind of infrared ray fixed point field of detecting, is specially adapted to the point position calibration of rolling stock infrared ray hot box detector.
At present, transportation by railroad department has generally adopted infrared temperature to survey or the thermal radiation monitoring device, be used to prevent vehicle hot box accident, on-the-spot when these equipment of installation, carry out verification to the infrared probe aiming point, the general now manual method that adopts, observe or calibrate with modes such as hand, fiery signals with eyes, this method blindness is big, and the layman is difficult for grasping, very difficult aligning is taken aim at a little, and a people does not implement yet.The optics of employing determination methods is also arranged in addition, but because the center of probe acceptance point and optical system exists deviation, also be difficult for calibration, these equipment all adopt laser and optical lens, make its cost higher, promote the use of and have any problem.The aiming point check and correction will definitely not make the monitoring effect of IR detection system obviously descend, particularly for transportation by railroad department, because the required detection of hot shaft detection device misalignment vehicle axle box position will have a strong impact on traffic safety.
The purpose of this utility model is the shortcoming of misalignment sensing point when overcoming above-mentioned infrared detector and installing, and provides a kind of easy grasp, price is low and can be for infra-red detection device sensing point prover single and layman's operation.
Technical solution of the present utility model is achieved in that a kind of infra-red detection device sensing point prover, it is characterized in that: it is made up of sensing point simulator and signal receiver-indicator, the sensing point simulator is the CD rotation that a circular hole is arranged by motor drives by an electric heating body, be modulated into simulation infrared radiation source, be installed on the coordinate adjustment rack, but constitute the sensing point of a simulating vehicle axle box optional position, the signal receiver-indicator is by direct supply, signal amplifier, rectifier, reometer is formed, and in its outside motor is housed, the thermal source interface, the signal testing interface, probe interface, the infrared equipment interface.Its feature also is, the coordinate adjustment rack by fixed screw, holder, horizontal mobile slideway, move up and down slide rule, move horizontally bar and formed, being installed in the width of cloth on the frame penetrates the source and can move arbitrarily in the space, the position that simulation needs, connect relative interface circuit during calibration, during the alignment probe sensing point, reometer shows maximal value, thereby reaches the purpose of calibration.
Now describe embodiment of the present utility model in conjunction with the accompanying drawings in detail:
Fig. 1, sensing point simulator structural representation
Fig. 2, signal receiver-indicator structural representation
Fig. 3, infra-red detection device sensing point prover scheme of installation
Among the figure:
1, sensing point simulator 9, miniature cocurrent electromotor

8, move horizontally bar 16, rail
A kind of infra-red detection device sensing point prover is made up of sensing point simulator and signal receiver-indicator; Wherein the sensing point simulator is by electric heating body 10 before the installation motor, drive CD 11 rotations that a circular hole is arranged by direct current motor 9, be modulated into simulation infrared radiation source, it is installed on the coordinate adjustment rack, the coordinate adjustment rack is by fixed screw 4, holder 5, horizontal mobile slideway 6, moves up and down slide rule 7, moves horizontally bar 8 and form.The width of cloth is penetrated the source and can be moved arbitrarily in the space on adjustment rack, and the simulation of different parts is realized in simulating vehicle axle box optional position.The signal receiver-indicator is made up of direct supply 12, signal amplifier 13, rectifier 14, reometer 15, and motor, thermal source interface, signal testing interface, probe interface, infrared equipment interface are installed in the outside of instrument.
During use, by fixed screw 4 the sensing point simulator is fixed on the rail 16, adjust the mechanism on the coordinate adjustment rack, realization is to the simulation of axle box different parts, signal receiver-indicator 2 is directly gone here and there between probe 2 and infrared equipment, connect each interface circuit, behind probe 2 aiming analog detection points 1, form signal and on reometer 15, show maximal value, thereby determine aiming point accurately through amplifier 13, rectifier 14.Signal is surveyed and is shown that interface can be when train passes through, and measured signal is observed with oscillograph or Other Instruments to popping one's head in.Probe interface is equipped with the changeover plug seat of different model, goes for different probe patterns.
The utlity model has following advantage:
1, simple in structure, easy to operate, can use for single or layman.
Do not affect normal use when 2, operating, can near probe, analyze by measured waveform.
3, owing to directly use probe received signal, calibration accuracy height.
4, be applicable to the infrared thermal radiation fixed point of any form sniffer.
