Description

Technical Field

[0001] The utility model belongs to the technical field of industrial Internet of Things intelligent monitoring, and specifically relates to a vibration monitoring sensor for industrial equipment. Background Art

[0002] In modern industrial production, stable equipment operation is crucial to production efficiency and product quality. Equipment vibration often provides a direct reflection of its health. Therefore, real-time monitoring and analysis of equipment vibration is crucial for preventing equipment failures and improving maintenance efficiency.

[0003] Currently, there are many vibration sensors on the market for monitoring equipment vibration. However, these sensors still have some significant drawbacks when used:

[0004] 1. Complex structure: Traditional vibration sensors usually contain multiple independent modules, such as data acquisition module, processing module, transmission module, etc. These modules are combined together through complex connection methods, resulting in a complex overall structure and inconvenient installation and maintenance.

[0005] 2. Difficulty in battery replacement: Many sensors are powered by built-in batteries. When the batteries are exhausted, the sensors need to be completely disassembled for replacement. This not only affects work efficiency, but also poses safety risks when replacing batteries in certain special environments (such as high temperature, high pressure, etc.).

[0006] 3. Single installation method: Traditional sensors often have only one or a few installation methods, which limits their applicability in different devices and environments.

[0007] 4. Limited transmission methods: Some sensors only support wired transmission, which limits their flexibility and application scope. Sensors that use wireless transmission may affect the real-time and accuracy of data due to signal interference or transmission distance limitations. Utility Model Content

[0008] The purpose of the present utility model is to provide an industrial equipment vibration monitoring sensor to solve the problems raised in the background technology.

[0009] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0010] The utility model proposes an industrial equipment vibration monitoring sensor, comprising:

[0011] The cover and the base are straight plates that can be detachably assembled on the lower end surface of the cover. The top of the base has a square protrusion.

[0012] A PCB module, which is assembled on the upper end surface of the base and located in the square protrusion, and includes a PCB board and an MCU, a vibration acquisition chip, and a 4G unit arranged thereon;

[0013] A touch switch, which is mounted on the upper end surface of the cover and electrically connected to the PCB module, and is used to control the on / off of the sensor;

[0014] A power supply module is assembled on the upper end surface of the base and is located in the square protrusion, and is used to supply power to the PCB module and the touch switch.

[0015] Furthermore, the space below the square protrusion includes a first partition and a second partition, the PCB module and the touch switch are located in the first partition, and the power supply module is located in the second partition.

[0016] Furthermore, the cover is specifically an injection molded part, and the base is specifically a metal part.

[0017] Furthermore, a plurality of threaded holes are provided on the outer peripheral edge of the base.

[0018] Furthermore, a bottom cover is detachably provided on the lower end surface of the base corresponding to the power supply module, so as to be used for separately removing the battery in the power supply module from the bottom.

[0019] Furthermore, a light-transmitting aperture is provided on the outer edge of the touch switch, and when the switch button is touched, the light-transmitting aperture flashes.

[0020] The beneficial effects of the present invention are:

[0021] 1. The sensor housing has a nearly integrated exterior surface with no obvious assembly or disassembly interface. All assembly and disassembly structures are located at the bottom or side. It utilizes a metal structure with a plastic main body, resulting in light weight and compact size. A touch-sensitive switch is used on the top for easy on / off operation.

[0031] In this embodiment, the vibration acquisition chip is used to collect vibration signals from the vibration device and transmit them to the MCU. The vibration acquisition chip specifically supports X, Y, and Z three-axis data acquisition, and its frequency response range is 0.1 to 2000 Hz; the MCU is used to process the vibration signal into a vibration index value (the index value includes the effective value, peak-to-peak value, kurtosis, margin, impact energy ratio and waveform of the vibration), the 4G unit is used to transmit the index value to an external network or platform, and the Bluetooth chip is used to connect the sensor to the handheld terminal.

[0032] As can be understood, this embodiment provides a vibration monitoring sensor that contains only a power supply module 4 and a PCB module 3. The overall structure is simple, and the battery can be removed separately from the bottom without affecting the installation of the PCB board, making battery replacement relatively convenient. The cover 1 has a nearly integrated surface, with no obvious assembly and disassembly interface. All assembly and disassembly structures are located on the bottom or side. The touch switch 5 has no obvious protruding button structure, allowing it to connect to external platforms via the 4G network.

[0033] Further preferably, the space below the square protrusion includes a first partition 7 and a second partition 8, which are specifically divided by a partition 6 vertically arranged inside the cover body 1. The PCB module 3 and the touch switch 5 are located in the first partition 7, and the power supply module 4 is located in the second partition 8.

[0034] More preferably, the cover 1 is an injection molded part, and the base 2 is a metal part. A plurality of threaded holes 9 are provided on the outer edge of the base 2 .

[0035] It should be noted that the vibration monitoring sensor in this embodiment has two installation methods: Installation Method 1: A magnetic attraction is provided at the bottom of the base 2, allowing for quick and portable installation and easy removal on large and small metal equipment in the factory. Installation Method 2: The base 2 is provided with a plurality of threaded holes 9 on the outer edge for screw connection to factory equipment.

[0037] Further preferably, a light-transmitting aperture is provided on the outer edge of the touch switch 5, and the light-transmitting aperture flashes when the switch button is touched.

[0038] According to the above embodiment, when the sensor is used, the product is installed on the machine housing or motor housing through the above installation method. The miniaturized device can monitor the vibration waveform on the vibration equipment and collect its index value, which is directly uploaded to the platform through the 4G network. The platform records the historical information of the measuring points, and has a complete understanding of the long life cycle of the machine. When the vibration waveform is abnormal, the fault type can be obtained in the first time.
