Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to an intelligent data proximity sensor test recorder. Background Art

[0002] With the rise of the subway industry, technology is becoming more and more advanced, and the demand for intelligent equipment is also increasing. A proximity sensor is a device used to detect the approach of an object. It can sense the existence and distance of an object without direct contact with the object. The effective height of the track surface that the proximity sensor can sense is the key to the train stopping at the station. Therefore, the accuracy of the installation height measurement and sensitivity of the proximity sensor is an urgent problem to be solved.

[0003] The existing measurement method is to manually calibrate and measure the height of the proximity sensor from the rail surface using tools such as a ruler and a water main line. This traditional measurement method is inefficient and produces large errors. The collected data is not accurate enough and it is easy for the proximity sensor to fail to sense the rail surface proximity disk information, thereby creating a driving safety hazard. In addition, the existing measuring device is not convenient to adjust the length according to the different spacings of the rails, and its flexibility is not high. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, one purpose of the utility model is to propose an intelligent data proximity sensor test recorder, which replaces manual measurement with instrument measurement, makes the measurement more intelligent, and determines the optimal installation height of the sensor by measuring the height between the rail surface and the vehicle proximity sensor, which is conducive to personnel quickly completing the installation of the proximity sensor. After installation, it will not affect the existing equipment. The measured height is also relatively accurate, which can greatly improve the work efficiency of night construction workers.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an intelligent data proximity sensor test recorder, comprising a detection bracket, a mounting seat and a laser rangefinder, wherein the detection bracket is located at the upper ends of two rails, the mounting seat is arranged above the detection bracket, the laser rangefinder is located inside the mounting seat, and the detection bracket comprises a rod bracket and a fixed rod, and the rod bracket is arranged at both ends of the fixed rod.

[0007] Preferably, the length of the fixing rod is smaller than the distance between the two rails, and the top end of the fixing rod and the top end of the rail are located in the same horizontal plane.

[0008] Preferably, a compression plate is provided inside the mounting seat, and the compression plate is fixedly connected to the mounting seat via a compression spring.

[0009] Preferably, a sliding groove is provided inside the fixed rod, and the rod bracket is slidably connected to the sliding groove via a sliding block.

[0010] Preferably, a positioning plate is fixedly provided at the lower end of the sliding block, and positioning holes are provided inside the positioning plate and at the bottom of the fixed rod.

[0011] Preferably, the mounting seat is fixedly connected to the fixing rod by screws, and the bottom of the laser rangefinder located inside the mounting seat contacts the top end surface of the fixing rod.

[0012] Preferably, the top end surface of the mounting seat is an iron box sensing surface.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The intelligent data proximity sensor test recorder of the utility model replaces manual measurement with instrument measurement, and the measurement is more intelligent. By measuring the height between the rail surface and the vehicle proximity sensor, the optimal installation height of the sensor is determined, which is conducive to the personnel to quickly complete the installation of the proximity sensor. After installation, it will not affect the existing equipment. The measured height is also relatively accurate, which can greatly improve the work efficiency of nighttime construction workers. The test device can be fixed on the side of the track to provide remote monitoring of rail surface height changes. The vehicle proximity sensor can collect and analyze data more accurately, provide more accurate information for signal professional on-board maintenance, and ensure the driving safety of the subway.

[0015] 2. The intelligent data proximity sensor test recorder of the utility model has an adjustable length of the detection bracket. The overall length of the detection bracket can be increased by sliding between the rod bracket and the fixed rod, so that the detection bracket can adapt to rails of different spacings, and has high flexibility and practicality. When the laser rangefinder is placed inside the mounting seat, the extrusion plate presses against the laser rangefinder under the action of the extrusion spring, so that the laser rangefinder is clamped in the mounting seat and is not easy to move, thereby ensuring the accuracy of the measurement.

[0024] In this embodiment, the intelligent data proximity sensor test recorder includes a detection bracket 1, a mounting seat 2 and a laser rangefinder 3. The detection bracket 1 is located at the upper ends of two rails, the mounting seat 2 is arranged above the detection bracket 1, the laser rangefinder 3 is located inside the mounting seat 2, and the vehicle proximity sensor 6 is located above the laser rangefinder 3. The detection bracket 1 includes a rod bracket 4 and a fixed rod 5. The rod bracket 4 is arranged at both ends of the fixed rod 5. The detection bracket 1 is made of stainless steel and thin material. The fixed rod 5 is placed in the middle position between the two rails. The rod brackets 4 at both ends are placed on the rails as fulcrums, so that the top end surface of the fixed rod 5 is kept in the same horizontal plane as the top end surface of the rail, and the center position of the upper end of the fixed rod 5 A laser rangefinder 3 is placed at the position, and a fixed rod 5 is used to solve the horizontal plane error. Zero-error measurement technology is realized through the laser rangefinder 3. The existing laser rangefinder 3 on the market is equipped with a mobile phone that can be connected to the mobile phone via Bluetooth or WIFI while realizing basic functions. The measurement data can be synchronized to the mobile phone, which is convenient for recording data and saving in real time. It is also convenient for on-site staff to extract and analyze data. The connection technology based on Bluetooth or WIFI realizes remote monitoring of the height of the vehicle approaching sensor 6 from the rail surface, realizes the functions of remote monitoring of equipment and log storage and downloading. Equipment management personnel can view the rail surface height change log, make statistics and predictions on the rail surface height change, adjust the rail surface status in time, and improve the operation efficiency and stability of the equipment.

[0025] In this embodiment, the length of the fixing rod 5 is less than the distance between the two rails, and the top end of the fixing rod 5 and the top end of the rail are located in the same horizontal plane.

[0026] The mounting seat 2 is fixedly connected to the fixing rod 5 by screws. The bottom of the laser rangefinder 3 located inside the mounting seat 2 contacts the top end face of the fixing rod 5. The mounting seat 2 is a square iron box. The laser rangefinder 3 is placed in the mounting seat 2. The bottom of the laser rangefinder 3 contacts the horizontal plane of the top end of the rail as the base point. The existing laser rangefinder 3 supports front and rear dual reference modes. When testing the installation height, the distance from the rear reference to the vehicle proximity sensor 6 is the installation height value, thereby achieving zero error testing.

[0027] The top end face of the mounting base 2 is the iron box sensing surface 203. When testing the sensing height, make a square iron box the same as the mounting base 2 and put the laser rangefinder 3 in it. Use the top iron box sensing surface 203 to approach the detection surface of the upper vehicle approaching sensor 6. When the light of the vehicle approaching sensor 6 is on, it indicates an effective sensitivity value. Record the maximum distance sensing height value. The distance to the vehicle approaching sensor 6 equals the sensing height value, i.e., the sensitivity value, by adding the front reference of the laser rangefinder 3 to the distance to the vehicle approaching sensor 6.

[0029] In this embodiment, a slide groove 501 is opened inside the fixed rod 5, and the rod bracket 4 is slidably connected to the slide groove 501 through a sliding block 401. Through the sliding between the rod bracket 4 and the fixed rod 5, the overall length of the detection bracket 1 can be increased, so that the detection bracket 1 can adapt to rails with different spacings.

[0030] A positioning plate 402 is fixedly provided at the lower end of the sliding block 401 . Positioning holes 502 are provided inside the positioning plate 402 and at the bottom of the fixed rod 5 . The positioning holes 502 are used to cooperate with the positioning pins to position the rod bracket 4 .

The sliding between the rod bracket 4 and the fixed rod 5 can increase the overall length of the detection bracket 1, so that the detection bracket 1 can adapt to rails with different spacings. The mounting seat 2 is fixed at the center position of the fixed rod 5, and the bottom of the laser rangefinder 3 located inside the mounting seat 2 contacts the top end surface of the fixed rod 5. The bottom of the laser rangefinder 3 contacts the horizontal plane of the top of the rail as the base point. When testing the installation height, the base is used later The distance to the vehicle approaching sensor 6 is the installation height value, thereby realizing zero error testing. When testing the sensing height, a square iron box identical to the mounting base 2 is made separately, and the laser rangefinder 3 is placed in it. The sensing surface 203 of the top iron box is used to approach the detection surface of the upper vehicle approaching sensor 6. When the light of the vehicle approaching sensor 6 is on, it indicates that it is an effective sensitivity value. The maximum distance sensing height value is recorded. The distance to the vehicle approaching sensor 6 equals the sensing height value, i.e., the sensitivity value, by adding the front reference of the laser rangefinder 3 to the distance to the vehicle approaching sensor 6. The laser rangefinder 3 is connected to the mobile phone via Bluetooth or WIFI to synchronize the measurement data to the mobile phone. The equipment management personnel can view the rail surface height change log, make statistics and predictions on the rail surface height change, adjust the rail surface status in time, and improve the operation efficiency and stability of the equipment.
