Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vibration monitoring sensors, in particular to an acoustic-vibration-temperature integrated sensor for patrol inspection. Background Art
[0002] There are many mechanical devices in modern industrial equipment. In order to detect the healthy operation status of mechanical equipment, equipment operators need to conduct regular inspections. Conventional inspection methods require carrying a vibration meter to measure the vibration of the equipment and an infrared thermometer to measure the bearing temperature. At the same time, the measurement results must be recorded in a temporary record book and the data must be re-transcribed into the inspection record when returning to the post. There are many devices to carry during the inspection process, the workload of data transcription is large, and manual transcription is prone to errors.
[0003] With the rise of IoT devices, there are now integrated temperature and vibration inspection and measurement instruments. The main principle is to integrate the sensor vibration chip and the temperature measurement chip into the same sensor through an integrated circuit board. The sensor can simultaneously collect the vibration information and temperature information of the device, and use these vibration data and temperature data to judge the health status of the device. However, the existing temperature and vibration measuring instruments still have some areas that need urgent improvement in actual use. The main disadvantages are: 1. The test signal is limited to temperature and vibration, and cannot detect sound, and cannot judge the health status of the device by abnormal sound; 2. The inspection sensor is relatively bulky and not conducive to handheld operation; 3. For machines and equipment that are not convenient for human hands to touch, the health status of the equipment cannot be detected by the inspection sensor. Summary of the invention
[0004] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the utility model is to provide an integrated acoustic, vibration and temperature sensor for inspection, which can detect sound, vibration and temperature at the same time, is easy to hold and operate, and can detect machinery and equipment that are inconvenient for human hands to touch.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A sound, vibration and temperature integrated sensor for inspection, including a sensor base 5, a data acquisition integrated circuit board 8 is connected inside the sensor base 5, and a vibration sensor, a sound sensor and an infrared temperature sensor 4 are integrated on the data acquisition integrated circuit board 8; the upper end of the sensor base 5 is connected to a sensor upper cover 6, a data transmission integrated circuit board 9 is connected inside the sensor upper cover 6, and the input of the data transmission integrated circuit board 9 is connected to the output of the data acquisition integrated circuit board 8; an aviation plug 7 is connected to the sensor upper cover 6, and the aviation plug 7 is connected to the output of the data transmission integrated circuit board 9; the lower end of the sensor base 5 is connected to a ring magnet 3; the center of the lower end of the sensor base 5 is connected to a plug 10, or is connected to an extension rod 1 through a hand-tightened nut 2.
[0007] The data acquisition integrated circuit board 8 collects the original data of sound, vibration and temperature uploaded by the device. The original data is processed by the data transmission integrated circuit board 9 and connected to the mobile phone through the aviation plug 7, and the health status of the device is directly displayed by the mobile phone app.
[0008] The infrared temperature sensor 4 is located in the center hole of the annular magnet 3 .
[0009] The data acquisition integrated circuit board 8 is connected to the sensor base 5 by screws.
[0010] The sound sensor on the data acquisition integrated circuit board 8 and the sensor base 5 have a sound cavity, and a sealing ring is provided between the sound cavity and the substrate of the data acquisition integrated circuit board 8 .
[0011] The temperature measuring chip of the infrared temperature sensor 4 on the data acquisition integrated circuit board 8 and the back of the sensor base 5 are sealed by glue potting.
[0012] The sensor base 5 and the sensor upper cover 6 are connected by welding, and the aviation plug 7 and the sensor upper cover 6 are connected by double sealing of glue filling and sealing ring.
[0013] The sensor base 5 and the sensor cover 6 are designed in an arc shape, which is ergonomic.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. Since the data acquisition integrated circuit board of the utility model integrates a sound sensor on the basis of integrating a vibration chip and a temperature chip, it can simultaneously detect the sound, vibration and temperature parameters of the equipment when it is running, and the judgment of the equipment failure is more comprehensive.
[0016] 2. Since the utility model adopts the solution of arranging the infrared temperature measurement chip in the center hole of the annular magnet to effectively reduce the volume of the sensor, the sensor has the advantages of compact structure and small appearance. In addition, its appearance adopts an arc design, which is ergonomic and convenient for handheld measurement.
[0017] 3. Due to the design of the measuring extension rod of the utility model, the utility model has the advantage of convenient and quick measurement in the usage scenario where it is inconvenient for human hands to touch. BRIEF DESCRIPTION OF THE DRAWINGS
