Embodiment 1
[0037] see figure 1 with figure 2 , the invention discloses a track valve opening feedback device, which includes a valve position indicator rod 1, a transmission mechanism 2, a valve position detection element 3, which can also be called an AM module, and a receiving module 4, which can also be called a BM module, wherein The track valve indicator rod 1 is a rod-shaped component that indicates the opening of the track valve. The transmission mechanism 2 includes an upper link 21, a lower link 22, a fixed ring 23 and a slip ring 24. The fixed ring 23 is fixedly set on the valve position indicator bar 1. At the top, the slip ring 24 is slidingly socketed with the valve position indicating rod 1, the fixed ring 23, the upper connecting rod 21, the lower connecting rod 22 and the slip ring 24 are sequentially hinged, the upper connecting rod 21, the lower connecting rod 22 and the valve position indicating rod 1 An angle-adjustable triangular structure is formed. The valve posi...
Embodiment 2
[0075] Compared with Embodiment 1, the present embodiment also includes data processing in step 3 of the valve position detection method of the track valve opening feedback device, and the data processing method includes the following steps:
[0076] Step 1: Data collection: Accumulate 100 continuous valve opening value data for the first time;
[0077] Step 2: Data sorting: Remove the largest 10 data and the smallest 10 data from the data collected in step 1; for example, collect 100 data continuously, and number them from 1 to 100, and then divide the 100 data by Sort from small to large, then remove the top 10 data and the last 10 data respectively, and calculate the average value of the remaining 80 data;
[0078] Step 3: Data processing: calculate the average value of the remaining 80 data in step 2, and output the average value of the valve opening;
[0079] Step 4: Collect again: collect data for the second time with the 11th data collected last time as the starting po...
Embodiment 3
[0083] The difference between this embodiment and Embodiment 2 is that in order to further increase the scope of use of the echo device, the detection method of the echo device has been further optimized, specifically, the upper part of the detection step 1 of the valve position detection element has been adjusted. , the corresponding relationship between the lower limit position and the maximum and minimum values of the actual valve opening, which can be specifically set by adjusting the distance between the fixed ring 23 and the slip ring 24 corresponding to the maximum and minimum valve openings. You can choose to adjust the height of the valve position indicating rod 1, specifically as Figure 5 with 6 As shown, the distance between the fixed ring 23 and the slip ring 24 corresponding to the maximum opening of the valve is set as L Amin , set the distance between the fixed ring 23 and the slip ring 24 corresponding to the minimum opening of the valve as L Amax , L Ami...
