What can you do with vibration measurement? ?

When you think of vibration measurement, you may first think of it as industrial equipment that is required in factories and FA equipment. Naturally, equipment used in factories and other facilities uses motors to drive them, fans and compressors to manage air, and vibrations occur even under normal conditions.

However, this vibration may affect the durability and reliability of the equipment, and damage and abnormal stoppages may cause equipment lifespans and malfunctions. In addition, vibrations are present not only in industrial equipment but also in buildings and structures in our daily lives, and by measuring vibrations before abnormal stoppages or breakdowns occur, we can prevent large Avoiding problems becomes important. Additionally, being able to measure and monitor vibrations remotely, without the need for constant human recording and maintenance, will also lead to a reduction in the burden and man-hours of patrol personnel.

This time, we will introduce a solution that allows you to easily and inexpensively perform PoC verification of vibration measurement using cloud connectivity, based on the following points.

1. What is predictive maintenance?

Positioning of predictive maintenance

There are three main types of maintenance work called maintenance.

(1) Corrective maintenance: Repairs and parts replacement are performed after equipment functionality deteriorates or suddenly stops. In other words, you must take action only after something abnormal occurs.
(2) Periodic maintenance: Regardless of the condition of the equipment, this is a method of regularly determining maintenance cycles based on failure records, operating hours, equipment characteristics, etc., and performing inspections and parts replacement.
(3) Predictive maintenance: By measuring and monitoring the condition of equipment based on normal operating conditions, we can grasp the state of deterioration, predict failures, and replace or repair parts at the optimal timing.

Effects of predictive maintenance

In addition, the types and impacts of each maintenance are summarized below, and predictive maintenance is effective in the following cases.

 

・Facilities and equipment that have a low frequency of failure but have a large impact in the event of a failure are targeted.
・Vibration measurement can be applied to all equipment with vibration, but it may be effective even in cases where the impact of failure is large as described above, or when resources for maintenance personnel are required.

2. How to easily measure vibration?

(1) This package solution uses UQuest's vibration analysis system (EMQuest-VA) to analyze the vibration frequency of equipment to detect equipment abnormalities such as unbalance, looseness, poor foundations, and damage to rolling bearings. You can determine whether this is occurring. A 3-axis MESM acceleration sensor (ADXL356) from Analog Devices, Inc. is used for vibration measurement pickup, and supports low noise density (80μg√Hz) and high G (±20g).

・Low price achieved by using MEMS acceleration sensor
・Acquire acceleration and calculate velocity and FFT (Fast Fourier Transform) values
・When vibration exceeding a set threshold is measured, an alarm can be raised using the contact (Digital Output).
- Save data to SD card and monitor past status. It is also possible to save only the data before and after the alarm is raised.
・FFT analysis results can be displayed in real time by connecting a PC

(2) CANDYLINE's Gateway (CANDY Pi Lite) and cloud development environment & execution environment (CANDY EGG) are used for cloud connection for vibration measurement. The application is also open source, so it is freely available.

<Gateway>
・Equipped with Raspberry Pi3 Model B+
・Equipped with 4G/LTE/3G-compatible cellular module (compatible with Docomo and Docomo-based MVNOs. Other carriers are tested at any time)
・Communication speed (standard connection: maximum 460Kbps for both uplink and downlink)

＜Cloud＞
・Cloud database construction, device communication, dashboard function
・Server can be used up to 5GB
・ Source code (available from GitHub)
