There areconductive nails 25 , which are inserted into the sides of thebase 21 and communicate with the lateralconductive rubber strips 22 or the longitudinalconductive rubber strips 23 . The arrangement of theconductive nails 25 is to facilitate the connection of the horizontalconductive rubber strip 22 and the longitudinalconductive rubber strip 23 to other circuits. For example, in the present invention, when the conductive rubber strip is connected to themulti-select switch 30, only theconductive nails 25 and 30 need to be connected by wires. Themulti-selection switch 30 is sufficient, and the wires are not shown in FIG. 2 and FIG. 4 , because there are too many lines, which will affect the display of other components.

The length of the thirdsmall diameter section 132 of theouter core 13 is greater than the thickness of thefoam layer 24. When thepushpin 10 is inserted into theplug board 20, the insulating core is Thesleeve 12 is located between the transverseconductive rubber strip 22 and the longitudinalconductive rubber strip 23 .

图像识别算法有很多，本发明中需要从白色的泡绵层24上识别出黑色的图钉相对来说较为容易，具体地，所述的步骤B中，按如下步骤获取图钉10位置信息：B1、移动终端拍摄插板20正面图像得到原始RGB图像，尽量拍摄正面图像，更有利于图钉10的识别；B2、对RGB图像进行梯形校正，考虑到拍摄时因角度问题，插板20周边轮廓肯定会发生畸变，不会是一个长方形，因此这里通过算法进行梯形校正，校正后的图像中插板20的轮廓为方形，有利于下一步处理；B3、根据设定好的阈值对校正后的RGB图像进行二值化处理得到黑白图像，黑白图像中黑色区域为图钉10、白色区域为背景，由于泡绵层24和图钉10的颜色有显著差异，因此将图像中的图钉10区域识别出来，只要通过阈值判断即可实现；B4、根据黑白图像中黑色区域面积大小筛选出真实图钉区域，这个步骤主要是用于去除噪点，一般通过膨胀和腐蚀处理后，再去掉面积较小的区域即可；B5、求解每个真实图钉区域的最小外接矩形并得到最小外接矩形的中心位置；B6、根据横向导电胶条22和纵向导电胶条23的个数将插板20分割成方形网格，获取每个真实图钉区域中心位置所处的网格编号。横向导电胶条22可以从上到下按数字进行编号，纵向导电胶条23可以从左到右按数字进行编号，这样就可以用两个数字代表图钉10的位置信息，比如{5，3}代表图钉10插置于第5个横向导电胶条22和第3个纵向导电胶条23相交的区域，需要对该图钉10进行提醒时，只需要导通这两个导电胶条形成回路即可。There are many image recognition algorithms. In the present invention, it is relatively easy to identify the black pushpin from thewhite foam layer 24. Specifically, in the step B, the position information of thepushpin 10 is obtained according to the following steps: B1, The mobile terminal captures the front image of theplugboard 20 to obtain the original RGB image, and tries to capture the frontal image, which is more conducive to the identification of thepushpin 10; B2. Perform keystone correction on the RGB image. Considering the angle problem during shooting, the peripheral contour of theplugboard 20 will definitely be If the distortion occurs, it will not be a rectangle. Therefore, the keystone correction is performed by the algorithm here. The outline of theinsert board 20 in the corrected image is square, which is conducive to the next processing; B3. The corrected RGB image is corrected according to the set threshold. Perform binarization to obtain a black and white image. In the black and white image, the black area is thepushpin 10 and the white area is the background. Since the colors of thefoam layer 24 and thepushpin 10 are significantly different, to identify thepushpin 10 area in the image, as long as the Threshold judgment can be achieved; B4. Screen out the real pushpin area according to the black area in the black and white image. This step is mainly used to remove noise. Generally, the area with a smaller area can be removed after expansion and corrosion treatment; B5 , Solve the minimum circumscribed rectangle of each real pushpin area and obtain the center position of the minimum circumscribed rectangle; B6. Divide theplug board 20 into square grids according to the number of the horizontal conductive rubber strips 22 and the longitudinal conductive rubber strips 23, and obtain each The grid number where the center of the real pin area is located. The horizontal conductive rubber strips 22 can be numbered from top to bottom, and the vertical conductive rubber strips 23 can be numbered from left to right, so that the position information of thepushpin 10 can be represented by two numbers, such as {5, 3} It means that thepushpin 10 is inserted in the area where the fifth horizontal conductiveadhesive strip 22 and the third vertical conductiveadhesive strip 23 intersect. When thepushpin 10 needs to be reminded, it is only necessary to conduct the two conductive adhesive strips to form a loop. .

以上述及到的阈值可以根据经验值来设定好，但是当插板20所处的环境光线有差异时或者图钉10和插板20本身的颜色有偏差时，之前设定的阈值就不一定准确，影响识别效果。本发明中优选地，所述的B3中，阈值范围可以按照如下步骤进行设定：B31、在插板20上任意位置插上多个图钉10；B32、拍摄插板20正面图像并进行梯形校正，这个图像我们可以拍摄多张，每张图像中又有很多的图钉10；B33、人工标记梯形校正后的RGB中图钉区域；B34、根据标记出的图钉区域每个像素的R、G、B值计算得到阈值范围{[R_MIN,R_MAX],[G_MIN,G_MAX],[B_MIN,B_MAX]}，这里的计算方法有很多，可以根据最大值、最小值、平均值或随机范围来计算阈值范围，只要保证其中80％～95％的像素的R、G、B值均位于阈值范围内即可；所述的B3中，校正后的RGB图像中R、G、B值位于阈值范围内的像素点记为1，位于阈值范围外的像素点记为0。这里的步骤B31-B34相当于校正，无需经常求解，只需要在环境变化较大或者识别率低下的时候执行这些步骤即可。The above-mentioned threshold can be set according to the empirical value, but when the ambient light where theplug board 20 is located is different or the color of thepushpin 10 and theplug board 20 itself is different, the previously set threshold value is not necessarily Accuracy affects the recognition effect. In the present invention, preferably, in the B3, the threshold range can be set according to the following steps: B31, insert a plurality of push pins 10 at any position on theboard 20; B32, take a front image of theboard 20 and perform keystone correction , we can take multiple pictures of this image, and each image hasmany pushpins 10; B33, manually mark the pushpin area in the RGB after keystone correction; B34, according to the R, G, B of each pixel in the marked pushpin area The value is calculated to obtain the threshold range {[R_MIN ,R_MAX ],[G_MIN ,G_MAX ],[B_MIN ,B_MAX ]}, there are many calculation methods here, which can be based on the maximum value, minimum value, average value or random range to calculate the threshold range, as long as the R, G, and B values of 80% to 95% of the pixels are all within the threshold range; in the aforementioned B3, the R, G, and B values in the corrected RGB image are within the threshold range. The pixels within the threshold range are marked as 1, and the pixels outside the threshold range are marked as 0. Steps B31-B34 here are equivalent to correction, and do not need to be solved frequently, and only need to perform these steps when the environment changes greatly or the recognition rate is low.

电源正负极通过多选开关30连接横向导电胶条22和纵向导电胶条23，通过调节多选开关的档位，保证每次只有一个横向导电胶条22和一个纵向导电胶条23经过LED灯珠导通，现有技术中的这种多选开关30的结构有很多种，但其档位一般都比较少，不适合这里的较多的档位，而且大部分都是手动操作的。这里提供了两种较为优选的多选开关30结构供参考。The positive and negative poles of the power supply are connected to the horizontalconductive rubber strip 22 and the verticalconductive rubber strip 23 through themulti-select switch 30. By adjusting the gear position of the multi-select switch, it is ensured that only one horizontalconductive rubber strip 22 and one verticalconductive rubber strip 23 pass through the LED each time. The lamp beads are turned on.

Themulti-select switch 30 includes aswitch base 31 , amotor 32 , ascrew rod 36 , aslider 37 , apositive electrode piece 34 and anegative electrode contact 35 , themotor 32 and thescrew rod 36 are coaxially connected and themotor 32 is used to drive thescrew rod 36 to rotate. Themotor 32 and thescrew rod 36 are fixedly installed on theswitch base 31 and the axis of thescrew rod 36 is parallel to the board surface of theswitch base 31. Therod 36 and theslider 37 form a screw nut fit; theslider 37 is fixed with apositive plate 34, thepositive plate 34 includes asquare body 341 and apositive contact 342, and theswitch base 31 is provided with anegative contact 35, apositive contact 342 Consistent with the number ofnegative contacts 35 , only onepositive contact 342 communicates with thenegative contact 35 when themotor 32 drives theslider 37 to move at any position along the length of thescrew 36 . By arranging staggeredpositive contacts 342 andnegative contacts 35, it can be ensured that when theslider 37 drives thepositive plate 34 to move, different positive and negative contacts are connected, so that the gear can be replaced easily, and here is the The action of thepositive electrode sheet 34 is driven by the cooperation of the nut and the screw rod, and no manual operation is required. At the same time, the arrangement of multiple positive and negative contacts here avoids the rapid wear and tear of a single contact, prolongs the service life, and can also realize the connection of different positive and negative contacts within a small displacement range, and the response speed is fast.

进一步地，为了降低整个直线多选开关的尺寸，所述的开关底座31为方形，丝杆36的轴平行于开关底座31的长边，开关底座31的其中一条长边边缘处均匀间隔设置有细槽，细槽中插值有导电片构成负极触头35，导电片延伸至细槽外侧的部分开设有孔洞便于连接导线；正极片34的方形本体341垂直于开关底座31且平行于丝杆36的轴，方形本体341的下端边缘均匀间隔布置正极触头342且正极触头342的下端面与负极触头35的上端面相抵，方形本体341上开设有孔洞便于连接导线；两个相邻的负极触头35间距L₂大于两个相邻的正极触头342间距L₁且L_l+L₃＜L₂＜k*L_l/(k-1)，式中L₃和k分别是正负极触头的宽度个数。Further, in order to reduce the size of the entire linear multi-select switch, theswitch base 31 is square, the axis of thescrew rod 36 is parallel to the long side of theswitch base 31, and one of the long sides of theswitch base 31 is evenly spaced. A thin groove, a conductive sheet is inserted in the thin groove to form anegative electrode contact 35, and the part of the conductive sheet extending to the outside of the thin groove is provided with holes for connecting wires; thesquare body 341 of thepositive electrode sheet 34 is perpendicular to theswitch base 31 and parallel to thescrew rod 36 The lower end edge of thesquare body 341 is evenly spaced withpositive contacts 342 and the lower end surface of thepositive contact 342 is in contact with the upper end surface of thenegative contact 35, and thesquare body 341 is provided with holes for connecting wires; two adjacent The distance L₂ between thenegative contacts 35 is greater than the distance L₁ between the two adjacentpositive contacts 342 and L_l +L₃ <L₂ <k*L_l /(k-1), where L₃ and k are the positive and negative electrodes respectively The number of widths of the contacts.

间距L₁是两个相邻正极触头342中心线之间的间距，L₂也是同理，正负极触头的宽度L₃即这里的正极触头342和负极触头35的宽度一致且均为L₃。满足以上公式的前提下，在图11中，在第一个正负极触头相接触导通时，由于L_l+L₃＜L₂，所以第二、第三、第四……个正极触头342与对应的负极触头35之间的间距越来越大且不会导通，同时为了避免第十个正极触头342与第九个负极触头35距离过近导通，这里通过公式L₂＜k*L_l/(k-1)限制了个数k。这种结构非常简洁、可靠，实现起来非常可靠。使用时，只需要将公共端连接方形本体351上开设的孔洞、每个负极触头36都作为一个档位连接其他元器件即可，需要调档时，只需要驱动电机32转动一定角度即可，控制起来非常方便。The distance L₁ is the distance between the centerlines of two adjacentpositive contacts 342 , and the same is true for L₂ . The width L₃ of the positive and negative contacts is the same as the width of thepositive contacts 342 and thenegative contacts 35 here. Both are L₃ . On the premise of satisfying the above formula, in Figure 11, when the first positive and negative contacts are in contact and conducting, since L_l +L₃ <L₂ , the second, third, fourth... The distance between thecontact 342 and the correspondingnegative contact 35 is getting larger and larger and will not conduct. At the same time, in order to avoid the tenthpositive contact 342 and the ninthnegative contact 35 being too close to conduct, the The formula L₂ <k*L_l /(k-1) limits the number k. This structure is very simple, reliable, and very reliable to implement. When in use, it is only necessary to connect the common end to the hole opened on the square body 351, and eachnegative contact 36 can be used as a gear to connect other components. When the gear needs to be adjusted, it is only necessary to drive themotor 32 to rotate a certain angle. , it is very convenient to control.
