Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to fig. 1 to 8 and the embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
Referring to fig. 1, an embodiment of the present invention provides a rail collision test method, and a main flow of the rail collision test method is described as follows:
step 100: and acquiring the current image characteristic information of the currently detected railing.
The current image characteristic information is displayed in a picture form, and contains all image characteristics of the current railing to be tested, such as the length, width, color and other contents which can be displayed by photographing through a camera of the railing to be tested. The purpose of the acquisition is to determine what material the currently monitored balustrade is made of, and of course the process of testing is not allowed to carry out the process of painting and coating.
One embodiment of this step is for example: by installing a video camera or camera in front of the currently detected rail and then taking a picture of the currently detected rail, the content contains an image of the currently detected rail that is visible on one side.
Step 101: and carrying out matching analysis according to the material characteristic parameters stored in the preset railing material database and the current image characteristic information to determine the corresponding material characteristic parameters in the current image characteristic information, and defining the material characteristic parameters as material parameter information to be detected.
The balustrade material database is provided with images in the corresponding directions of all different balustrades with different sizes and all characteristic parameters such as the type, quality, density and the like of the balustrade materials corresponding to the images. Matching and matching the current image with the images stored in the database, and if the two photos are overlapped, the currently detected railing is the material corresponding to the overlapped photo.
The technical principle is similar to the hundred-degree identification chart, images of different railings can be stored in the cloud, and then the images are identified through the hundred-degree identification chart.
Step 102: and carrying out matching analysis according to the limit impact height stored in the preset impact limit database and the parameter information of the material to be detected so as to determine the corresponding limit impact height in the parameter information of the material to be detected, and defining the limit impact height as reference limit height information.
Wherein the reference limit height information is a height difference from the impact point and the start point. The impact limit database is obtained by tests by a person skilled in the art, the rails of different material types are tested at different heights, then the height which is to be achieved by tilting the rails beyond the standard range is taken as an example, and the test environment is a vacuum environment and has no external environmental influence. The impact limit database is used for mapping the material parameters and the limit impact height.
And comparing and searching the obtained parameter information of the material to be detected with data in a database to obtain limit impact height data. For example: an excel table mapping material parameters and limit impact heights is arranged in a computer end with execution capability, and codes are edited so that when the identified material is input into the computer end, the codes automatically call the excel table, then the corresponding limit impact height is found and then the display is output.
Step 103: and matching the image center height stored in the preset image shape database with the current image characteristic information to determine the image center height corresponding to the current image characteristic information, and defining the image center height as approved image center height information.
The image shape database stores the mapping relation between images with different shapes and the center height of the images, and the database is obtained by the workers in the field through calculation of the railings in the images with different shapes.
Matching and matching the current image with the images stored in the database, if the two photos are overlapped, the current detected railing is the shape corresponding to the overlapped photo, and then comparing and searching with the data in the database to obtain the center height of the image. For example: the method comprises the steps that an excel table mapping images with different shapes and image center heights is arranged in a computer end with execution capability, when image shape data are input into the computer end through editing codes, the codes automatically call the excel table, then the corresponding image center heights are found, and then output and display are carried out.
Step 104: and calculating the limit height information according to the reference limit height information and the approved image center height information.
Wherein, the limit height that corresponds in the limit height information is: h=h0+h1; h0 is the height corresponding to the reference limit height information, and h1 is the height corresponding to the center height information of the approved image.
Step 105: and calculating the height information of the current test stage according to the limit height information and the preset deviation height range information.
The deviation height range information is a difference range between the height of the height corresponding to the limit height information to the low point and the limit height information, and data in the range are all arithmetic difference data. The test is performed by offsetting the height range from the lowest height within the range and then incrementing in height according to the arithmetic data.
The corresponding height in the height information of the current test stage is as follows: h2 =h- Δh, where Δh is the corresponding arithmetic difference data in the deviation height range information.
Step 106: and acquiring current test result image information obtained by testing at different heights corresponding to the height information of the current test stage.
The current test result image information is an image of the shape and state of the railing after the impact test from the side surface of the railing, namely, the surface parallel to the swinging surface of the pendulum bob. The purpose of the acquisition is to obtain the effect that can be produced under different energy impacts. The acquisition mode can be any machine with an image capturing function for capturing an image. When each test is completed, the camera takes a picture immediately and stores it.
Step 107: according to the preset railing inclination angle stored in the railing inclination database, carrying out matching analysis with the current test result image information to determine the corresponding railing inclination angle in the current test result image information, and defining the railing inclination angle as approved railing inclination angle information.
The railing inclination database stores images of the railings in different inclination angles, an excel table with images of different inclination angles and inclination angle values mapped in a computer end with execution capability is stored in the railing inclination database, then the images stored in the railing inclination database are matched through software with a graph recognition function, and then output and display are carried out.
Step 108: comparing the inclination angle information of the approved railing corresponding to the current height with the safety inclination angle information corresponding to the current material stored in the preset material strength database.
The material strength database is data of impact strength values and inclination angle values of materials, which are obtained through multiple experiments by a person skilled in the art and are recorded in specifications. The safety inclination angle information is the inclination angle which can still maintain a certain structural strength after the railing is impacted, the safety inclination angle is recorded in building material standards, and the inclination angle is the included angle between the direction of the railing after the railing is inclined and the vertical direction.
Whether the rail is damaged or not is intuitively judged by comparing the inclination angle corresponding to the inclination angle information of the approved rail with the inclination angle corresponding to the safety inclination angle information, namely, comparing the angle.
Step 1081: if the inclination angle corresponding to the inclination angle information of the approved railing corresponding to the current height is larger than the inclination angle corresponding to the safety inclination angle information corresponding to the current material stored in the preset material strength database, the operation is not performed.
When the inclination angle corresponding to the inclination angle information of the approved railing corresponding to the current height is larger than the inclination angle corresponding to the safety inclination angle information corresponding to the current material stored in the preset material strength database, the inclination angle is indicated to exceed a critical value, and the current height is indicated to be damaged.
Step 1082: if the inclination angle corresponding to the inclination angle information of the approved railing corresponding to the current height is smaller than or equal to the inclination angle corresponding to the safety inclination angle information corresponding to the current material stored in the preset material strength database, the safety heights are recorded and are sequentially arranged, so that the test height with the highest safety height is selected, and the test height is defined as the test limit height information.
The test limit height information is the maximum limit height of the railing in the current railing test, which can still maintain the safety performance under the impact. A batch of limit heights with the inclination angle within the safe inclination angle are obtained through experiments, and then the limit heights are sequenced to obtain the highest height.
Step 109: and comparing the height corresponding to the test limit height information with the height corresponding to the reference limit height information.
The comparison mode is a numerical comparison mode, and any software capable of performing comparison can be used as the comparison mode.
Step 1091: and if the height corresponding to the test limit height information is greater than or equal to the height corresponding to the reference limit height information, recording as qualified.
When the height corresponding to the test limit height information is greater than or equal to the height corresponding to the reference limit height information, the limit height of the railing tested at this time is greater than the reference, and the railing is still in a safe state when the railing is in the state of the reference limit height.
Step 1092: if the height corresponding to the test limit height information is smaller than the height corresponding to the reference limit height information, recording as unqualified.
The height corresponding to the test limit height information is smaller than the height corresponding to the reference limit height information, which indicates that the limit height of the railing in the test is not greater than the reference limit height information, namely, the railing is possibly damaged when the railing is in the state of the reference limit height, and the railing in the test does not meet the requirement.
Referring to fig. 2, the control method of the pendulum striking the balustrade includes:
step 200: and acquiring induction time information on the railing.
Wherein the sensing time information is information such as the time that the pendulum and the railing contact the pendulum and the railing are separated when collision occurs on the railing, the information includes the time when the contact is made, the contact time, the time when the contact is released, and the like. The timer counts time when the test starts, namely when the pendulum falls, then when the pressure sensor at the impact point senses pressure, the computer records the numerical value on the timer as the moment when the pendulum just contacts, and when the pressure disappears, the computer records the numerical value as the moment when the pendulum is separated. The manner of acquisition may be a counting function app present on modern handsets.
Step 201: and acquiring current pressure information corresponding to the induction time information.
The current pressure information is a pressure value in the contact duration. The acquisition mode is that the pressure sensor senses and is processed and stored by the processing module.
Step 202: and comparing the pressure value corresponding to the current pressure information with the pressure value corresponding to the preset approval pressure information.
The preset approved pressure information is a preset pressure value, generally 0, and the comparison process is to judge whether the pendulum bob and the railing are separated. The comparison method is numerical comparison and will not be described herein.
Step 2021: if the pressure value corresponding to the current pressure information exceeds the pressure value corresponding to the preset approval pressure information, the current pressure information after the induction time information is continuously acquired.
When the pressure value corresponding to the current pressure information exceeds the pressure value corresponding to the preset approval pressure information, the pressure is indicated to exist, at the moment, which is not the moment when the rail and the pendulum are separated in the sensing time information, and the rail and the pendulum are not separated, so that the rail and the pendulum need to be observed continuously.
Step 2022: and if the pressure value corresponding to the current pressure information does not exceed the pressure value corresponding to the preset approval pressure information, braking the pendulum bob.
When the pressure value corresponding to the current pressure information does not exceed the pressure value corresponding to the preset approval pressure information, the time of first detachment is indicated, and the pendulum needs to be braked immediately. When the sensor senses that the pressure value corresponding to the current pressure information does not exceed the pressure value corresponding to the preset approval pressure information, the pendulum bob needs to be braked by the vertical horse, so that the pendulum bob cannot cause secondary impact on the railing. For example: when the sensor senses that the pressure disappears, the pendulum bob is rapidly clamped through the brake or the air cylinder, or a baffle plate is generated at the railing, is arranged in parallel with the railing and does not collide with the railing.
Referring to fig. 3, the method for determining the limit impact height corresponding to the parameter information of the material to be measured includes:
step 300: and matching different test reference heights stored in a preset height segmentation database with the approved image height information to determine different impact heights corresponding to the approved image height information, and defining the different impact heights as pre-impact height information.
The height segmentation database stores mapping relations between total height values corresponding to the railings in the approval image height information and different test reference heights, specifically, the railings are equally divided into proper equal parts according to actual height values of the railings, and then the center point of each equal part is marked as pre-impact height information. And when the computer end with the execution capability is provided with an excel table for mapping the total height value corresponding to the railing in the approved image height information and different test reference heights, and the total height value data corresponding to the railing in the approved image height information is input into the computer end by editing codes, the codes automatically call the excel table, then find the corresponding different test reference heights and output, display and mark.
Step 301: and acquiring the swing point height information of the pendulum bob.
The swing point height information comprises a height value of a rotation center point of the pendulum bob. The mode of acquisition can be any mode of measuring height, such as an infrared range finder. And irradiating the infrared rays to the swing point for measurement and storing the infrared rays to a computer terminal.
Step 302: and calculating the swing rope length information according to the swing point height information and the pre-impact height information, and adjusting the swing rope length.
Wherein, the length value L=L0-L1 in the swinging rope length information; wherein L0 is the height value of the impact point in the swing point height information, and L1 is the height value of the impact point in the pre-impact height information.
Step 303: and adjusting the angle of the swinging rope according to the limit height information.
The adjusting mode can be that the pendulum bob is fixedly connected with another pull rope, and the motor drives the pull rope to pull the pendulum bob. The starting point angle of the swinging rope is as follows: θ=arccos { (L0-H)/L0 }. Wherein L0 is the swing rope length corresponding to the swing rope length information. H is the height corresponding to the limit height information.
Referring to fig. 4, the method of checking the swing rope length information includes:
step 400: and acquiring information of an induction area after the pendulum bob is impacted.
The sensing area information is the area information formed by the number and the positions of the pressure sensors sensing the pressure value larger than 0, and comprises the sensing area, the sensing area, a central point, a boundary line and the like in the area. The method is to divide the length and width of the railing, uniformly arrange the pressure sensors as dense as possible, and form an area image on the computer end.
Step 401: and matching the impact area parameters corresponding to the preset area model database with the sensing area information to determine the impact area parameters corresponding to the sensing area information, and defining the impact area parameters as approved impact area parameter information.
