Person of ordinary skill in the field is set to be appreciated more fully and realize the present invention.But to those of skill in the art
Member is it is evident that the present invention's realizes some that can not have in these details.However, it should be understood that of the invention
It is not limited to introduced specific embodiment.On the contrary, it may be considered that with the arbitrary combination of features described below and element come
Implement the present invention, regardless of whether they are related to different embodiments.Therefore, aspect, feature, embodiment and advantage below is only
It is illustrative, and it is not to be taken as element or the restriction of claim, unless clearly proposing in the claims.
Fig. 1 shows according to an embodiment of the invention for testing the electromagnetism interference performance of vehicle window control module
System, Fig. 2 shows the partial side views of the system.
As shown in Figure 1, 2, which includes：Sample 1 to be measured, i.e. vehicle window control module；By vehicle window control module
The motor 2 of control；First pulley component, including pulley 31,32, the first rope 5 are wrapped in the rotor and pulley 31,32 of motor 2
Groove on；First sliding rail 6；Traction piece 7, the traction piece are fixed on the rope between pulley 31,32 and on the first sliding rail 6
Slidably；Traction piece 7 is fixed in one end of first pulley component, including pulley 4, the second rope 8, and the groove via pulley 4 prolongs
It stretches and is connected to load 9；Second sliding rail 10, has been placed equidistant with a plurality of light-emitting elements 11 thereon, and one end is fixed on traction piece 7
The detecting element 12 that shines is located at the top of the second sliding rail 10；Console (not shown), in the console via cable to vehicle window control
Molding block sends test signal, and will pass through the rotation that vehicle window control module controls motor, and the console is also via cable
It is communicated with luminous detecting element.
During electromagnetic compatibility test, the component other than console may be contained in electromagnetic environment, so as to vehicle
The electromagnetism interference performance of window control module is assessed.
Load 9 can be the counterweight for being equal to vehicle window weight for simulating by motor-driven vehicle window.In fig. 2, it loads
9 be pendency, i.e., is moveable in the vertical direction, this was arranged for the case where shaking window motor, and load certainly can also be set
It is set in the horizontal direction or is moveable on other directions, such as skylight motor.
Console (testing terminal) can send test signal (for example, direction is (just by optical cable to vehicle window control module
Turn/reversion), power supply, pulse and/or enable signal etc.), wherein passing through two photoelectric conversion devices inside and outside test environment successively
By electric signal to optical signal, optical signal to electric signal this opto-electronic conversion twice.It thus is avoided that and is input to vehicle window in test signal
It is influenced in advance by electromagnetic interference before control module.
When vehicle window control module receives the test signal from console, and driving motor rotates, due to the rotation of rotor
Turn, drives the first rope 5 to be moved on the rotor of motor 2 and the groove of pulley 31,32, so that being fixed on the first rope 5
On traction piece 7 slided on the first sliding rail 6 so that the second rope 8 of traction piece 7 is fixed on via pulley 41 in one end
Groove moves, and thus tows the load one that the other end of (this corresponds to the case where upward larry window) the second rope 8 is connected
Play movement.
During traction piece 7 slides on the first sliding rail 6, the luminous detecting element on traction piece 7 is fixed in one end
12 also synchronously move in the top of the second sliding rail 10, therefore, can be with setting in the moving process for shining detecting element 12
A plurality of light-emitting elements 11 on the second sliding rail 10 in turn face one by one.
Light-emitting component 11 is, for example, infrared light-emitting diode, shine detecting element 12 for example including infrared receiving diode,
Counter, photoelectric conversion unit.Light-emitting component 11 and luminous detecting element 12 are by carrying or external power supply is powered.Shine detection
The circuit part of element 12 can be packaged by metal shell, to shield the electromagnetic interference of ambient enviroment, to avoid detecting
As a result it is influenced by electromagnetic interference environment.Before testing, it should to counter O reset.
For example, being set as the distance between luminous detecting element 12 and the second sliding rail 10 to meet the value of the following conditions：When
The infrared receiving diode that the infrared light-emitting diode being arranged on second sliding rail 10 includes with luminous detecting element 12 is substantially just
Clock synchronization, infrared receiving diode can receive the infrared ray that infrared light-emitting diode is sent out.For example, distance between the two can be with
To be less than or equal to 10 millimeters.
When infrared receiving diode receives the infrared ray that infrared light-emitting diode is sent out, triggering setting is in the detection that shines
Counter in element 12 makes it add 1, and the count value is transmitted to console in real time, according to the count value, console
Scheduled distance between testing time of record, light-emitting component can estimate each hair passed through in the detecting element 12 that shines
Corresponding speed at 11 position of optical element, so as to monitor the velocity variations of simulation vehicle window being supported in entire test process
(acceleration or deceleration), to find influence of the electromagnetic interference environment to motor operation, i.e., to the vehicle window control module of driving motor
Influence.
As a specific illustrative numerical example, can shine adjacent in a plurality of light-emitting elements being placed equidistant with
The distance between element is set as 5 millimeters, and the distance between the light-emitting component that head and the tail both ends are on the second sliding rail is set as
300 millimeters.
In order to ensure the precision of test, count value can be converted into optical signal from electric signal by photoelectric conversion unit,
Except optical cable transmission to test environment (electromagnetic environment), the optical signal is then converted into electricity using electrooptical device
Signal, for transmission to console, the influence this avoid electromagnetic interference to measuring accuracy.
Luminous detecting element 12 and console directly by cable transmission signal in the case of, can be made an uproar with removal electromagnetism
The filter of sound replaces the electrooptical device outside photoelectric conversion unit and test environment in luminous detecting element 12 respectively.
Although the foregoing describe exemplary embodiment of the present invention, the present invention is not limited thereto.Technical field
Technical staff can make various changes and modifications, without departing from the spirit and scope of the present invention.The scope of the present invention only by
Claim limits.
