Description
Technical field
The present invention relates to the Mechanical test facilities technical field, is a kind of simulation test device for test radar velocity measurement performance quality, specifically a kind of analogue experiment installation for the test radar.
Background technology
Tradition is for testing the speed on the track railway, need radar to test, yet the quality of the radar that tests the speed just need radar to install ON TRAINS, carrying out actual vehicle-mounted experiment just can carry out, need the complete race of train one circle, aptitude test, and need repeatedly test, cost is high, both inconvenient, need again to waste a large amount of time and manpower and materials, greatly affect efficient.
Summary of the invention
Whether the present invention provides a kind of device that imitates train operation to replace true train, thereby can work by the quick test radar for overcoming the deficiencies in the prior art, greatly reduces cost, both convenient, time saving and energy saving again.
For achieving the above object, design a kind of analogue experiment installation for the test radar, comprise anterior cylinder, stern roll, belt, electromagnetic-wave absorbing rubber, back up pad, support, it is characterized in that: the support upper left side is provided with stern roll, the right side is provided with anterior cylinder on the support, adopt belt gear to be connected between anterior cylinder and the stern roll, described anterior cylinder adopts driving belt connection motor.
Also be provided with upper backup pad and lower supporting plate on the support between stern roll and the anterior cylinder from top to bottom, described upper backup pad is positioned at the top of the annular ring of belt formation, and described lower supporting plate is positioned at the bottom of the annular ring of belt formation; Be evenly equipped with screw on the upper backup pad.
The upper surface of described lower supporting plate is provided with electromagnetic-wave absorbing rubber.
The present invention compares with prior art, can simulate the railway practical operation situation, comprise the weather such as the actual water of simulation, ice, snow, replace actual track test, can the quick test radar whether can carry out normally, the work of testing the speed accurately, greatly reduce the testing cost of radar, and in device, increase electromagnetic-wave absorbing rubber, can effectively filter out clutter, improve the correctness of radar velocity measurement test, both convenient, time saving and energy saving again.
Description of drawings
Fig. 1 is structural representation of the present invention.
Referring to Fig. 1,1 is stern roll, and 2 is belt, and 3 is electromagnetic-wave absorbing rubber, and 4 is lower supporting plate, and 5 is support, and 6 is anterior cylinder, and 7 is upper backup pad.
Embodiment
The present invention is described further with reference to the accompanying drawings for the below.
As shown in Figure 1, support 5 upper left sides are provided with stern roll 1, and the right side is provided with anterior cylinder 6 on the support 5, adopt belt 2 to be in transmission connection between anterior cylinder 6 and the stern roll 1, and described anterior cylinder 6 connects motor by driving-belt respectively.
On the support between stern roll 1 and the anterior cylinder 6, also be provided with upper backup pad 7 and lower supporting plate 4 from top to bottom, described upper backup pad 7 is positioned at the top of the annular ring of belt 2 formation, and described lower supporting plate 4 is positioned at the bottom of the annular ring of belt 2 formation; Be equipped with screw on the upper backup pad 7, the screw here plays certain supporting role to the upper strata belt, prevents the upper strata sag of belt.
The upper surface of lower supporting plate 4 is provided with electromagnetic-wave absorbing rubber 3.
When radar speed sensor is carried out testing authentication, first radar is suspended in the top of apparatus of the present invention, again by 1 rotation of motor-driven stern roll, afterwards drive together rotary moving of belt 2 and anterior cylinder 6, then switch on to radar, allow the travelling speed of radar test belt 2, check and accept radar and whether work thereby detect.Because strap lug is outside anterior cylinder 6 and stern roll 1, therefore total some belt is positioned at the top of anterior cylinder 6 and stern roll 1, in addition some belt is positioned at the below of anterior cylinder 6 and stern roll 1, in this example respectively referred to as " upper strata belt " and " lower floor's belt ".
On this basis, also can hold the materials such as water, ice, snow with vessel on lower supporting plate 4, whether the check radar can carry out work under complicated weather conditions, carry out many-sided performance test, more can accurately detect the performance of radar.
During test, after radar sent microwave, the microwave of a part was reflected another part microwave penetration upper strata belt by the upper strata belt; A part that penetrates in the microwave of upper strata belt is absorbed by electromagnetic-wave absorbing rubber 3, and another part microwave that penetrates in the microwave of upper strata belt has been transmitted on lower floor's belt; The a part of microwave that is transmitted in the microwave on lower floor's belt continues to penetrate lower floor's belt, the microwave that penetrates lower floor's belt no longer forms the reflection wave with Doppler shift, another part microwave that is transmitted in the microwave on lower floor's belt will reflect back, and the microwave that reflects back then can be absorbed by electromagnetic-wave absorbing rubber 3.
For example: the DRS05S1c radar is the unique a kind of velocity radar that uses in the present Chinese high ferro train control system, and the effect in the high ferro safe operation is very important.This radar microwave frequency 25.125GHz, radar microwave power 5mw.
During test, after radar sent microwave, the microwave of a part reflected another part microwave penetration upper strata belt through the upper strata belt; A part that penetrates in the microwave of upper strata belt is absorbed by electromagnetic-wave absorbing rubber 3, and another part microwave has been transmitted on lower floor's belt; The a part of microwave that is transmitted in the microwave on lower floor's belt continues to penetrate lower floor's belt, the microwave that penetrates lower floor's belt no longer forms the reflection wave with Doppler shift, another part microwave will reflect back, and the microwave that reflects back then can be absorbed by electromagnetic-wave absorbing rubber 3.
According to Doppler effect, there are a difference in reflection wave and emission wave frequency, i.e. Doppler effect, and the formed frequency change of Doppler effect is called Doppler shift, and the size of Doppler shift and the velocity magnitude of belt are directly proportional.The direction of motion of upper and lower layer belt is opposite, can produce the Doppler shift of opposite direction.The microwave that reflects back from lower floor's belt can bring huge interference to radar test, so electromagnetic-wave absorbing rubber 3 will reduce the microwave that is transmitted into lower floor's belt, and absorbs the microwave that reflects back from lower floor's belt, makes it can not bring interference to radar test.Radar can be exported the motion velocity information of upper strata belt thus.
So just can whether can work by instrumentation radar, carry out basic functional test.
For example the DRS05S1c radar is the unique a kind of velocity radar that uses in the present Chinese high ferro train control system again, and the effect in the high ferro safe operation is very important.When now this radar being tested the speed the hatred performance test, use apparatus of the present invention, this radar microwave frequency 25.125GHz, radar microwave power 5mw, the test speed scope is 0-40km/h, reflective power is about 15% to 30% like this, can the belt in this test unit be tested the speed by the DRS05S1c radar, and can this radar carry out normally, the work of testing the speed accurately thereby test out.
By the rotating speed of motor is set, can detect radar and whether can measure the speed of object in certain speed range, such as 0-300km/h, and the precision of measuring, for example the DRS05S1c radar can reach 0.4% deviation.
