Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
Examples
As shown in FIG. 2, the application provides a confession bullet lift fault early warning detector, including casing 8, the detector adopts full metal casing, and is sturdy and durable, and heat dispersion is good. As shown in fig. 1, the detector is specifically disposed outside the carriage of the feeder elevator. The housing 8 is provided with a plurality of mounting feet 12. The mounting feet 12 are plate-shaped and are arranged on the side of the housing 8. The device only needs to fix four mounting feet 12, and can complete all mounting without any extra work, and the mounting is convenient.
As shown in fig. 5, a single-axis accelerometer 1, a micro control unit 2, an external memory 3 and a USB interface chip 4 are arranged in a housing 8, the single-axis accelerometer 1, the micro control unit 2(MCU), the external memory 3 and the USB interface chip 4 are all connected with a power management chip 5, and the power management chip 5 is connected with a battery 6. The external memory 3 can adopt a Flash chip, and the battery 6 adopts a button battery. The USB interface chip 4 is provided with a USB interface 7, and the USB interface 7 extends out of the top of the shell 8. The hardware of the fault early warning detector is a System On Board (System On Board), and the PCB is arranged as shown in FIG. 6.
The USB interface 7 is provided with a protective cover 9. As shown in fig. 3, the protective cover 9 is connected to the top of the housing 8 by screws 10. 2 screws 10 on the protective cover 9 of the USB interface 7 are unscrewed, and after the USB interface 7 is exposed, a USB wire is connected, and then the communication with a PC 13 can be realized.
As shown in fig. 4, the housing 8 is designed to be separated from the top and bottom, and the screws 10 at the four corners are unscrewed, so that the housing 8 can be opened, the battery 6 can be replaced, or the PCB inside the housing can be removed for maintenance. Such a design facilitates routine maintenance of the detector.
The motion track data is obtained by averaging vertical displacement errors of a displacement track obtained by calculating acceleration data, and the vertical displacement errors are obtained by subtracting an actual maximum value from a theoretical maximum value of vertical displacement.
The fault early warning detector can record the motion trail of a bracket during the working of the bullet supply lifter, is detached from the lifter regularly, guides a motion trail data file in the detector into the PC (personal computer) 13 through the USB interface 7, and checks the motion trail through matched PC end software in the PC 13. If the movement track is abnormal, the ammunition supply elevator needs to be repaired and maintained.
As shown in fig. 7, the specific working process is as follows: the single axis accelerometer 1 periodically sends acceleration data to the micro control unit 2 via the on-board bus. Acceleration data are processed by a program in the micro control unit 2, converted into a motion track, and written into a data file in the external memory 3 through an on-board bus. After the device is connected with a USB data line, the motion trail data file is copied into the PC 13 through the USB interface 7.
The single-axis accelerometer 1 adopts a low-pass filtering algorithm, wherein the low-pass filtering algorithm is a filtering method for removing signals with frequencies higher than a certain threshold value and only allowing low-frequency signals to pass through, and has a good filtering effect on acceleration signals.
The uniaxial accelerometer 1 itself contains noise, and the displacement obtained by calculation must contain error by adding the accumulated error of the integration step. In order to reduce errors, the detector adopts an end point flattening method. The displacement end points are 2 points, one is at the lowest point, namely zero point, and the other is at the highest point, namely top point. When the detector is driven to the highest point by the ammunition feeding lifter, the calculated value S of the vertical displacement is calculatedHigh fruitThen using the maximum theoretical value S of the vertical displacementmaxSubtract SHigh fruitObtaining a vertical displacement error value Delta SHeight of。
ΔSHeight of＝Smax-SHigh fruit，
Then the error Delta S is calculatedHeight ofSpread out into the ascending motion track.
When the detector is driven to the lowest point by the ammunition feeding lifter, the calculated value S of the vertical displacement is calculatedLow fruit contentThen using the minimum theoretical value S of the vertical displacementminI.e. 0 minus SLow fruit contentObtaining the vertical displacement error value Delta SIs low in。
ΔSIs low in＝0-SLow fruit content，
Then the error Delta S is calculatedIs low inIs spread out into the descending motion track. For "end-point flattening", a single axis accelerometer 1 is already sufficient.
The motion trail curve obtained by the device is a two-dimensional plane curve, the horizontal axis is a time axis t, and the vertical axis is displacement S. The normal motion trajectory curve should be smooth as shown in fig. 9. If the motion trail curve has a platform line segment, as shown in fig. 10. It is indicated that the feeder elevator needs maintenance and can resolve the potential failure risk in advance.
The micro control unit 2 of the detector can be written by adopting products of NXP company and standard C language and assembly language, and has good real-time performance.
The motion trail display software at the end of the PC 13 can be developed by Visual C + +. After the motion trail data file is imported into the PC 13 from the detector, the motion trail data file is directly opened by the display software, so that a motion trail curve can be displayed, and the specific flow is shown in fig. 8.
