Embodiment
Contrast accompanying drawing below, through the description to embodiment, specific embodiments of the invention is done further detailed explanation, to help those skilled in the art inventive concept of the present invention, technical scheme is had more complete, accurate and deep understanding.
Like the structure of the present invention that Fig. 1 expresses, for a kind of securing band height is regulated experiment control system, described height is regulated test and is carried out on the height adjuster of securing band.
In order to solve the problem that exists at the described present known technology of this instructions background technology part and to overcome its defective, realize the durability degree of car belt and the goal of the invention of the detection in serviceable life, the technical scheme that the present invention takes is:
As shown in Figure 1, securing band height provided by the invention is regulated experiment control system and is comprised 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 stop at diverse location; And then continuation descending motion; So need be on differing heights sensor installation 2; In order to gather the height and position information of height adjuster,, make corresponding action with servomotor 5 by control module 1 control cylinder 4 to send to control module 1.
In order to make height adjuster in the certain hour scope, ceaselessly, the circulation pump the cycle index of external counter 3 computed altitude regulators.
When described height adjuster moved to the peak position, described control module 1 was controlled the button that described cylinder 4 simulation staff are pushed height adjuster according to the position signalling of the collection of described sensor 2, makes it press or lift;
Drive the downward vertical motion of height adjuster by described servomotor 5; When arriving a certain height node; The position signalling that described control module 1 is gathered according to described sensor 2, the rotation of controlling described servomotor 5 with stop, realizing the decline of height adjuster and stop.
Described control module 1 input end is established node options button 6.
In order to satisfy under the differing heights condition height adjuster is carried out long duration test, described control module 1 is connected with node options button 6, in order to the height of switching height adjuster rising, and the up-down that in the corresponding height scope, moves in circles.
Corresponding with it, described sensor 2 is also corresponding with the height node.
Described cylinder 4 is arranged on the peak of described height adjuster movement locus.
When moving to the peak position, control module 1 is according to the position signalling of the collection of sensor 2, and control cylinder 4 simulation staff are pushed the pressing and lifting of button of height adjuster.
Described servomotor 5 is arranged on the minimum point of described height adjuster movement locus.Drive upwards vertical motion of height adjuster 40 by it, when arriving a certain height node, the position signalling that controller 10 is gathered according to sensor 2, the commentaries on classics of control servomotor 5 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 the station button 7 that is used to control described single-chip microcomputer break-make electricity.
The present invention also provides above-described securing band height to regulate the test control method that experiment control system adopts, and like Fig. 2, Fig. 3 and shown in Figure 4, this test control method may further comprise the steps:
A, install when height adjuster, 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 the extreme higher position by the servomotor counter-rotating; After getting back to original position, cylinder 4 is opened, servomotor 5 is just changeing, and beginning is toward first high degree of motion;
B, arrive first height after, servomotor 5 stops, cylinder 4 is closed, servomotor 5 setting in motion again behind the pause 100ms, cylinder 4 is opened, toward next high degree of motion;
Repeat step b again behind c, the next height of arrival; Otherwise entering next step;
D, arrive last height after, servomotor 5 stops, cylinder 4 is closed, behind the pause 100ms, servomotor 5 counter-rotating is toward the initial point motion;
E, in returning the process of initial point, the cycling time of detecting 2s is to not having; If arrived, just detect origin position, a loop ends gets into next circulation; If no, just express possibility and break down, press fault alarm and handle, simultaneously cylinder 4, servomotor 5 stop motions;
Arrive the number of times of setting when cycle index after, servomotor 5 stop motions, long duration test finishes.
Below be example with four height of node:
When height adjuster installs, select correct height node options button 6 states, press station button 7; The original position that the button of height adjuster is got back to the extreme higher position by servomotor counter-rotating promotion; After getting back to original position, cylinder 4 is opened, servomotor 5 is just changeing, and beginning is toward first high degree of motion;
Arrive that servomotor 5 stops behind first height, cylinder 4 is closed, servomotor 5 is opened again toward second high degree of motion with cylinder 4 behind the pause 100ms;
Arrive that servomotor 5 stops behind second height, cylinder 4 is closed, servomotor 5 setting in motion again behind the pause 100ms, cylinder 4 is opened toward the 3rd height setting in motion;
Arrive that servomotor 5 stops behind the 3rd height, cylinder 4 is closed; Servomotor 5 counter-rotatings are toward the initial point motion behind the pause 100ms; The cycling time of in returning the process of initial point, detecting 2s, if to just detecting origin position, a loop ends got into next circulation to not having; If be not exactly to express possibility to break down, press fault alarm and handle, simultaneously cylinder 4, servomotor 5 stop motions;
No matter owing to adopt several height nodes, this securing band height is regulated the test control method and can be suitable for, so other highly steps of the test method of some that repeat no more.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
