Description
Technical field
The present invention relates to a kind of running train bogie of car and underframe imaging and temperature measuring equipment.
Background technology
The present invention is associated with rolling stock security monitoring system 5T system middle infrared (Mid-IR) determination system of train wheel axles (THDS).Infrared journal temperature detection system ensures safety of railway traffic, prevent freight train vehicle contingent in operational process, because vehicle bearing temperature anomaly raises, cause and produce overheated bearing breaking, the i.e. important traffic safety monitor and control facility of the serious traffic safety accident of so-called vehicle overheating of axle bearing.
Infrared journal temperature detection system (THDS) from last century the seventies in China railways vehicle safety monitoring system, be progressively generalized to existing more than 40 year history now.System equipment is from the evolution THDS employing till now always of artificial interpretation the earliest Computerized intelligent technology, there is counting shaft with axle counter, intelligent-tracking, measurement axle box temperature and automatic early-warning hot box function under train operation state, and realize the working state of system of " dispersion detection, concentrated alarm, networking operation, information sharing ".But its TEMP is the temperature that a single-point type normal temperature thermally dependent resistor outside the difference alignment bearings by being installed on rail limit and a low temperature mercury cadmium telluride temperature sensor inside alignment bearings realize gathering bearing inner side and outer side.Problems existing is: 1, can only detect the local temperature value in bearing internal external point type scanning area, the high temperature foreign matter produced when factors such as train brakes falls in the regional area of sensor scan, then there will be false-alarm phenomenon, its false alarm rate is high, cause train temporary term stop, cause serious economic loss and bad social influence thus; 2, owing to being serpentine locomotion when train is advanced, it rocks rate about ± 30 millimeter, and due to the reason such as flat wheel phenomenon and rail rail level scratch of wheel, rail vehicle is in operation and often there will be the situation of bob, sensor is difficult to the same position of alignment bearings, there is leaking the situation visiting wrong spy to can hardly be avoided, temperature value inaccuracy, poor reliability that it detects; Its accuracy rate of reporting to the police is only about 70%, can not ensure train safe, reliability service well.3, the local temperature of bearing can only be detected, and the temperature of whole bearing and wheel can not be detected, when other spot temperature of wheel and bearing may produce train accident extremely, cannot report to the police, produce serious train operating safety hidden danger.
Summary of the invention
The object of this invention is to provide a kind of running train bogie of car and underframe imaging and temperature measuring equipment, this device can be measured and comprise bearing, the whole bogie truck of wheel and the temperature data of floor underframe for vehicle and distribution thereof.Its temperature survey more accurately and reliably, can be reported to the police to axle temperature distribution is abnormal, can report to the police again, can also come off and report to the police, significantly improve the accuracy rate of warning, ensure safe train operation more comprehensively, reliably chassis member the warm abnormal distribution of wheel.
The present invention realizes its goal of the invention; the technical scheme adopted is: a kind of running train bogie of car and underframe imaging and temperature measuring equipment; its composition is: rail feel at ease dress one or more rail heart array focal plane infrared thermal imaging sensors, a trackside array focal plane infrared thermal imaging sensor is respectively installed in track both sides; Rail feel at ease dress one or more rail heart visual light imaging devices, a trackside visual light imaging device is respectively installed in track both sides.
Described rail heart array focal plane infrared thermal imaging sensor, trackside array focal plane infrared thermal imaging sensor, rail heart visual light imaging device are all connected with the industrial computer on rail limit with trackside visual light imaging device.
Working process of the present invention and principle are: in the bogie truck detecting by train respectively by rail heart array focal plane infrared thermal imaging sensor and trackside array focal plane infrared thermal imaging sensor, the infrared temperature distributed image of the various assembly in outside sends industrial computer to; Simultaneously rail heart visual light imaging device and trackside visual light imaging device shoot by train bogie truck respectively in the visible images of the various assembly in outside, send industrial computer to.Industrial computer carries out image co-registration process to the infrared temperature distributed image received and visible images, obtain the temperature distribution image of bogie sole bar clear-cut and the Temperature numerical of sign, and carry out bearing temperature alarm accurately according to the Temperature numerical of bogie truck bearing.
Compared with prior art, the invention has the beneficial effects as follows:
One, the bogie truck entirety of the bogie truck entirety become by rail heart trackside array focal plane infrared thermal imaging sensor combining data detection and the infrared temperature distributed image of chassis member and the shooting of rail heart trackside visual light imaging device and the visible images of chassis member, the temperature distribution image of bogie sole bar and chassis member clear-cut and the Temperature numerical of sign is obtained after carrying out fusion treatment, when the fusion treatment of image, automatically the high temperature foreign matter that the factors such as train brake produce can be removed, avoid prior art Yin Gaowen foreign matter and fall into the false-alarm phenomenon occurred in the regional area of sensor scan, greatly reduce its false alarm rate, avoid because the temporary term stop of false-alarm train causes serious economic loss and bad social influence.
Two, fail to report owing to avoiding single-point type thermally dependent resistor because of the rocking of train, the axle temperature caused of beating, misrepresent deliberately problem, the temperature of bearing can accurately reliably be detected all the time, its bearing temperature alarm rate accuracy improves greatly, can ensure train safe, reliability service well.
Three, the present invention can obtain the temperature distribution image of whole bogie sole bar and chassis member clear-cut and the Temperature numerical of sign, bearing temperature distributed data can be drawn, also the temperature profile data of wheel can be obtained, and by the temperature profile data of industrial computer according to wheel, analysis judges whether phenomena of the failure such as heat wheel occurring, flat wheel, vehicle wheel crack, wheel lockup and component come off, and then carry out the warning of these phenomena of the failure, eliminate the potential safety hazard produced because of wheel et out of order, ensure safe train operation more comprehensively, reliably.
Be further, whole component and the whole component of underframe inside bogie truck are contained in the superposition of the angle of field of one or more described rail heart array focal plane infrared thermal imaging sensors, and whole component and the whole component of underframe inside bogie truck are contained in the superposition of the angle of field of one or more rail heart visual light imaging devices; The angle of field of described trackside array focal plane infrared thermal imaging sensor contains whole components of bogie truck respective outer, and the angle of field of trackside visual light imaging device contains whole components of bogie truck respective outer.
Like this, can ensure that the bogie truck temperature distribution image obtained contains all components of bogie truck and underframe, the image of gained more comprehensively, intuitively, can reflect whether any component cracks, defect, misplace, the fault such as come off, to safeguard in time.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
