Embodiment
Contrast accompanying drawing below, the description by embodiment, is described in further detail the specific embodiment of the present invention, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present invention, technical scheme.
As the structure of the present invention that Fig. 1 expresses, be a kind of securing band height adjusting test control system, described height adjusting test is for carrying out on the height adjuster of securing band.
In order to solve the problem existing at the described current known technology of this instructions background technology part and to overcome its defect, realize the goal of the invention of the durability degree of car belt and the detection in serviceable life, the technical scheme that the present invention takes is:
As shown in Figure 1, securing band height adjusting test control system provided by the invention comprises control module 1, and the input end of described control module 1 is provided with sensor 2 and external counter 3, and the output terminal of described control module 1 is respectively equipped with cylinder 4 and servomotor 5.
Because height adjuster need to stop at diverse location, and then continuation descending motion, so need to be on differing heights sensor installation 2, in order to gather the height and position information of height adjuster, to send to control module 1, by control module 1 control cylinder 4 and servomotor 5, do corresponding action.
In order to make height adjuster within the scope of certain hour, ceaselessly, circulation pump, the cycle index of external counter 3 computed altitude regulators.
When described height adjuster moves to peak position, described control module 1, according to the position signalling of the collection of described sensor 2, is controlled the button that described cylinder 4 simulation staff are pressed height adjuster, makes it press or lift;
By described servomotor 5, drive the downward vertical motion of height adjuster, when arriving a certain height node, the position signalling that described control module 1 gathers according to described sensor 2, controls the rotation of described servomotor 5 and stops, and realizes the decline of height adjuster and stops.
Described control module 1 input end is established node options button 6.
In order to meet under differing heights condition, height adjuster is carried out to long duration test, described control module 1 is connected with node options button 6, the height raising in order to switch height adjuster, and the lifting that moves in circles within the scope of corresponding height.
Answer in contrast, described sensor 2 is also corresponding with height node.
Described cylinder 4 is arranged on the peak of described height adjuster movement locus.
When moving to peak position, control module 1 is according to the position signalling of the collection of sensor 2, and control cylinder 4 simulation staff are pressed the pressing and lifting of button of height adjuster.
Described servomotor 5 is arranged on the minimum point of described height adjuster movement locus.By it, drive upwards vertical motion of height adjuster 40, when arriving a certain height node, the position signalling that controller 10 gathers according to sensor 2, controls turning of servomotor 5 and stops, and realizes the rising of height adjuster and stops.
Described control module 1 adopts single-chip microcomputer, and described control module 1 is provided with for controlling the station button 7 of described single-chip microcomputer power on/off.
The experimental control method that the present invention also provides above-described securing band height adjusting test control system to adopt, as shown in Figure 2, Figure 3 and Figure 4, this experimental control method comprises the following steps:
A, when height adjuster installs, select the state of correct height node options button 6, press station button 7, the button of height adjuster is promoted the original position of getting back to extreme higher position by servomotor reversion; Get back to after original position, cylinder 4 is opened, servomotor 5 forwards, starts toward first high degree of motion;
B, arrive after the first height, servomotor 5 stops, cylinder 4 is closed, servomotor 5 setting in motion again after pause 100ms, and cylinder 4 is opened, toward next high degree of motion;
C, repeat again the following content in step b after arriving next height: servomotor stops, cylinder is closed, servomotor setting in motion again after pause 100ms, cylinder is opened, toward next high degree of motion; Otherwise enter next step;
D, arrive after last height, servomotor 5 stops, cylinder 4 is closed, and after pause 100ms, servomotor 5 reversions, toward initial point motion;
E, in returning the process of initial point, detect the cycling time of 2s to not having; If arrived, just detect origin position, a circulation finishes, and enters next circulation; If no, just express possibility and break down, press fault alarm and process, simultaneously cylinder 4, servomotor 5 stop motions;
When cycle index arrives after the number of times of setting, servomotor 5 stop motions, long duration test finishes.
Four height of node of take are below example:
When height adjuster installs, select correct height node options button 6 states, press station button 7, the button of height adjuster promotes the original position of getting back to extreme higher position by servomotor reversion, get back to after original position, cylinder 4 is opened, servomotor 5 forwards, starts toward first high degree of motion;
Arrive that servomotor 5 after the first height stops, cylinder 4 is closed, after pause 100ms, servomotor 5 and cylinder 4 are opened again toward the second high degree of motion;
Arrive that servomotor 5 after the second height stops, cylinder 4 is closed, servomotor 5 setting in motion again after pause 100ms, cylinder 4 is opened toward third high degree setting in motion;
Arrive that servomotor 5 after third high degree stops, cylinder 4 is closed, after pause 100ms, servomotor 5 reversions are toward initial point motion, the cycling time of detecting 2s in returning the process of initial point, if to just detecting origin position, a circulation finished to enter next circulation to not having; If not then mean and may break down, press fault alarm and process, simultaneously cylinder 4, servomotor 5 stop motions;
No matter owing to adopting several height nodes, this securing band height adjusting test control method can be suitable for, so repeat no more other highly steps of the test method of some.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
