The distance measuring sensor is arranged on the vehicle body reinforcing rib 9 through an adjusting part and faces the inner side of the wheel shaft 7, and the distance between the lower end face of the distance measuring sensor and the upper end face of the loop track is 60-80 mm.
The temperature sensor, the axial vibration sensor and the radial vibration sensor are all mounted on the wheel axle 7 in the form of an adhesive. The sensor lead line 14 is connected to an analog-to-digital converter of the data processing section.
The adjusting part is shown in fig. 4, and comprises a mounting base 10 mounted on a vehicle body reinforcing rib 9, a plurality of strip-shaped mounting holes formed in the mounting base 10, and a fixing bolt 12 which is connected with the mounting holes in a matched mode, wherein the ranging sensor is mounted in the mounting holes through the fixing bolt 12.
The mounting base 10 is shown in fig. 5, and the mounting hole is positioned at the middle lower part of the mounting base 10, and the extension length of the mounting hole is more than half of the length of the mounting base 10.
During concrete processing and manufacturing, the adjusting part is welded at the position of the vehicle body reinforcing rib 9 by 160mm 70mm 5mm stainless steel plates, two mounting holes are formed in the mounting base 10, and the adjusting part starts at the position 60mm away from the upper end face, symmetrically slots along the central line, and has the width of 4mm and the length of 90mm. The center line of the two slots is 42.5mm away.

Therefore, the data processing part consists of four data processing modules with the same configuration, and the data processing modules respectively process the acquired data of the four paths of sensors. Taking an axial vibration measuring part as an example, the signal processing module adopts a programmable logic device EPM7064SLC44 of Altera company as a CPLD to realize logic control. The analog voltage signal acquired by the sensor 1 is used as an input signal, and the AD9283 is used as an analog-to-digital converter to sample the signal voltage. Two IDT7204 of IDT company are used as data buffer, which can realize synchronous operation of FIFO and DSP chip and meet the data transmission requirement of AD and MCU. Since the output data of the FIFO and the CPLD are 5V levels, the connection with the data bus of the DSP must be performed through a 5V to 3.3V conversion chip. The 74LVC4245A manufactured by NXP Semiconductors company was selected as an 8-bit dual-power bi-directional level-shifting transceiver. The TMS320VC5402 DSP is selected as FFT processing, and the data result is obtained through software calculation and then is output to the FIFO buffer. Because the DSP program space is limited, the system mainly uses the DSP for data operation, utilizes ATMega 128-16AI as a function realization and processing unit, and outputs the result to a production line control system through a spare IO port of the loop vehicle deviation correcting system. The data processing of the temperature measurement and the ranging is basically the same as that of the vibration measurement part, and a description thereof will not be repeated. The final temperature, vibration and distance results are displayed on the monitoring screen of the operator's cab by the production line control system.
The specific implementation mode of the invention is as follows:
the KS95C100 miniature axial vibration sensor 1 and the KS95C100 miniature radial vibration sensor 2 are mounted as follows: the center line of the KS95C100 miniature axial vibration sensor 1 in the vertical direction coincides with the center line of the wheel shaft 7, and the distance between the edge vertex of the KS95C100 miniature axial vibration sensor 1 and the edge of the wheel shaft 7 and the edge of the wheel shaft oil filling hole 13 is not less than 5mm; the mounting position of the KS95C100 miniature radial vibration sensor 2 needs to be satisfied that the center line in the horizontal direction coincides with the center line of the wheel shaft 7, and the distance from the edge vertex of the KS95C100 miniature radial vibration sensor 2 to the end face of the wheel shaft 7 is 5mm. In order to meet the requirement of sensor installation, the sensor installation surface of the wheel axle 7 is subjected to leveling treatment, and then 200-400# abrasive paper is used for polishing the installation surface; washing the polished surface with absolute ethyl alcohol, and thoroughly wiping; and (3) dripping a proper amount of 502 quick-drying adhesive on the bonding part, pressing the sensor by hand for a few seconds, loosening the hand after the adhesive is primarily solidified, and standing for a dozen seconds to thoroughly solidify the adhesive to achieve bonding strength. The purpose of selecting the adhesive mounting mode is to facilitate later disassembly and assembly. The sensor adhered to the measured object is taken down, acetone is coated at the adhesion part, and the sensor is taken down after several minutes.
SA1XL surface thermocouple temperature sensor 3 mounting mode: the adhesive mounting mode convenient to disassemble and assemble is adopted, the operation steps are same as those of the KS95C100 miniature axial vibration sensor 1, and the selected mounting position is centrally symmetrical with the KS95C100 miniature axial vibration sensor 1.
Mounting of MSE-TS803-55/30 laser ranging sensor 11: a mounting base 10 is welded at the position of the vehicle body reinforcing rib 9 shown in fig. 4, the mounting base 10 is made of 160mm x 70mm x 5mm stainless steel plates according to fig. 5, and the MSE-TS803-55/30 laser ranging sensor 11 and the mounting base 10 are fixed by two fixing bolts 12 with the model number of M3 x 40.
MSE-TS803-55/30 laser ranging sensor 11 has two M3 bolt mounting holes for laser sensor fixation and position adjustment, and laser ranging sensor cable socket 8 shown in FIG. 3 is used for laser sensor power and data transmission. The MSE-TS803-55/30 laser ranging sensor 11 uses laser triangles to measure the distance to the object. The laser focusing lens 15 irradiates the surface of the object to be measured with laser light, and the receiving laser lens 16 receives the reflected laser light. The installation distance between the lower surface of the MSE-TS803-55/30 laser ranging sensor 11 and the upper surface of the track of the object to be measured is within the range of 70+/-10 mm, and the MSE-TS803-55/30 laser ranging sensor 11 outputs normal data; when the relative distance between the MSE-TS803-55/30 laser ranging sensor 11 and the surface of the vehicle rail exceeds the range of 70+/-10 mm, an alarm is output to prompt an maintainer to check the failure cause as soon as possible.
