Description
Technical field
The present invention relates to a kind of detection and caliberating device that is used to monitor the infrared hot box detection equipment that guarantees railway visitor, goods vehicle security of operation, particularly a kind of temperature measurement accuracy and the detection of probe orientation angles and the calibration instrument of using that adjustment is demarcated to this infrared hot box detection equipment more.
Background technology
At present, railway visitor, goods vehicle monitoring bearing variation of temperature in service are to prevent visitor, goods vehicle combustion axle and the key link of cutting axle, and in the trunk railway both sides in accordance with regulations the infrared hot box detection equipment that is provided with of distance be exactly the specialized equipment of railway visitor, for motor vehicle monitoring of goods vehicle axle temperature in service.Because of the vibrations in visitor, goods vehicle operational process, can make the infrared probe in its casing depart from the specified measurement position; Sometimes infrared probe damages and can change by occurrence positions when changing; The easier casing that makes moves when main line is safeguarded scarfing cinder, so can influence the accuracy of detection of infrared hot box detection equipment.In order to guarantee that these infrared hot box detection equipments can accurately detect the bearing temperature of vehicle in service and infrared probe thereof and accurately detect specified measurement position on the axle box of bearing place, must regularly detect and its infrared probe is demarcated these infrared hot box detection equipments.
Existing infrared hot box detection equipment detects that can it carry out accurately the vehicle bearing temperature, the used caliberating device of quantitative test, mainly takes two kinds of forms.A kind of is infrared hot box detection equipment detection of dynamic car; A kind of is the static calibration of infrared hot box detection equipment instrument.
Infrared hot box detection equipment detection of dynamic car is to be used for face infrared hot box detection equipment over the ground to carry out the special vehicle that dynamic real-time detects, devices such as simulation wheel, simulation axle box, direction ruler are installed in utilization additional on the inspection vehicle car body, receive the measurement result of ground infrared hot box detection equipment by wireless data sending simultaneously, detect the temperature measurement accuracy of ground infrared hot box detection equipment and the azimuth deviation degree of demarcating the infrared probe setting angle in it automatically inspection vehicle.Wherein simulate the axle box precise temperature control system probe temperature performance detection of face infrared hot box detection equipment over the ground, being called for short calibration detects, its essence is in the lower vehicle setting by adding the simulation axle box of hot dark matter plate as the standard heater, simulate true heated mandrel case, when the infrared ray inspection vehicle through under the car during infrared hot box detection equipment of ground, measuring system on ground infrared probe and the car, measure the temperature of simulation axle box on the car simultaneously, then the two is compared, whether accurate with the infrared probe thermometric of check ground infrared hot box detection equipment; What the simulation wheel was used for checking the ground infrared hot box detection equipment tests the speed, surveys function such as wheelbase; By heating to the orientation plate that has " Z " font special shape heating tank on the car, according to the heat distribution data acquisition waveform of ground infrared hot box detection equipment, check the infrared probe angle pointed in the infrared hot box detection equipment of ground to the special shape of direction ruler.
Although the detection of dynamic car has above-mentioned many characteristics, combine multinomial subjects such as machinery, thermal technology, optics, control automatically, computing machine and communication because of inspection vehicle, so its control system complexity, the manufacturing cost height influences its popularization and application; In addition, be subjected to the restriction of vehicle operating on the trunk railway, this inspection vehicle need be by dispatching the time interval of arranging to determine the time of operation and detecting infrared hot box detection equipment once more, the cycle of its image data result treatment is longer, no aid is revised detected error, can not accomplish instant discovery, the instant adjustment.Particularly when its high-speed cruising, the convection gas that is produced and the interference of braking often cause temperature significantly to vibrate, and sometimes even produce bigger overshoot, so can strengthen the temperature control difficulty of simulation axle box, do not reach the ideal control precision.
