Real-time monitoring system including Iot smart device using vibro-piezoelectric element

The present invention relates to an IoT (Internet of Things) smart device and a real-time monitoring system using a vibro-piezoelectric element, and more particularly, to an IoT smart using a vibro-piezoelectric element attached to rotating and vibrating facilities in an industrial plant site such as a power plant. By using the device to monitor the target facilities in real time from a remote location and display the results as visual information, the manager can easily check the abnormal state of the target facilities.

In particular, the present invention installs a self-powered vibrating piezoelectric element that produces electric energy using vibrations generated in target facilities, so that it can be installed in various facilities without restrictions on the installation of the target facilities as well as various vibration frequencies. Using a vibro-piezoelectric element that can generate electricity to operate an IoT smart device in response to, and wirelessly transmit the measurement data of the IoT smart device and monitor it in real time in an integrated management server to keep the target facility stable It relates to IoT smart devices and real-time monitoring systems.

In general, a number of facilities are being operated at industrial plant sites such as power plants, and in particular, facilities that continuously perform a constant motion, such as an electric motor, or facilities that generate a certain pattern of vibration through repetitive motion are being operated.

Most of these facilities are operated in conjunction, and when an error occurs in any one facility, the entire facility may be stopped or a dangerous situation may occur.

For this reason, it is necessary to continuously check whether each facility operates normally at the site.

However, in industrial sites such as power plants described above, not only are a large number of facilities densely configured in a wide space due to the operational characteristics of facilities, but also significant noise is generated from a large number of facilities, so check whether specific facilities are operating properly In order to do this, it was inconvenient that the manager had to visit the target facilities installed in a wide area one by one and check the operation status.

In order to solve this inconvenience, VMS (Vibration Monitoring System) is currently installed in power plants, etc., and monitoring is performed using HMI (Human Machine Interface). However, since VMS equipment itself is expensive, operation is limited to some important facilities. are doing

As described above, in industrial plant sites such as power plants, the operation of low-voltage vibrators and pumps, except for high-voltage motors, is not monitored. Failure to do so may affect the operation of the entire facility.

As a result, in order to efficiently operate various facilities at industrial plant sites such as power plants, monitoring of all necessary facilities and devices is required, so the development of monitoring devices and systems with low installation costs and easy operation and maintenance is difficult. was requested

As a technique for solving this problem, there is the following prior art document, Republic of Korea Utility Model Publication No. 20-2017-0002137 'a device for checking the operating state of a motor using a vibrating piezoelectric sensor' (hereinafter referred to as 'prior art').

The prior art relates to a device capable of confirming the operating state of an electric motor using electric energy generated by using a vibrating piezoelectric sensor, and although it generally satisfies the above-mentioned requirements, there are several disadvantages.

First, all facilities or devices have their own vibration frequency. In the case of the prior art, since the device operates only at a specific vibration frequency, in order to monitor a large number of facilities installed in the field, the vibration frequency generated by each facility is After checking, each device that operates at the relevant vibration frequency should be manufactured and installed.

Second, the vibration frequency of most facilities can be continuously changed in the process of operation, and in particular, when maintenance is performed, such as replacing specific parts, the vibration frequency can be significantly different during operation of the facility. Even though the device is operating normally, the installed prior art device fails to operate, and thus, it may be mistakenly mistaken for an abnormality in the corresponding facility.

Third, in order to solve this problem, it is necessary to replace the device of the prior art installed in the facility. When replacing, the vibration frequency of the facility must be re-measured, and a new device must be manufactured and installed accordingly. Since additional effort is required, there is a problem in that smooth operation is not achieved due to waste of money and time.

Fourth, even if the corresponding facility is stably maintained, a phenomenon may occur that cannot respond to the same vibration frequency due to performance change due to deterioration of the device itself of the prior art. There may be a problem that the device of the device misunderstands it.

The repeater 20 is configured to enable wireless transmission and reception with each IoT smart device 10 installed in the corresponding target facilities. possible, so it is not limited to a specific one.

In addition, the repeater 20 is installed in an optimal location where wireless transmission is easy from the IoT smart device 10 attached to the target facilities, and the integrated management server 30 uses wireless Wi-Fi and an intranet cable. Connectable, mainly by connecting a wired intranet cable and a power line so that the integrated management server 30 can stably collect real-time data.

The integrated management server 30 receives the real-time data of the IoT smart device 10 from the repeater 20, checks whether each target facility is operated, and manages the operation of the entire facility of the corresponding industrial plant. For example, the integrated management server 30 collects the real-time data of the target facility to which the IoT smart device 10 is attached by producing electric energy from the IoT smart device 10 through the repeater 20 to diagnose self-established. It is possible to control the IoT smart device 10 by determining a normal range compared to the algorithm data.

On the other hand, the integrated management server 30 may be linked through the administrator terminal 40 and the web (World Wide Web) and app (APP: application) used by the administrator. Here, the manager terminal 40 may include a PC, a notebook computer, a PDA, a smart phone, a tablet, and the like.

Accordingly, the integrated management server 30 is controlled by the manager, and in conjunction with the manager terminal 40, it is possible to monitor real-time data transmitted from the IoT smart device 10 of the corresponding facility and remotely control it.

When the vibration frequency is changed in this way, due to the characteristics of the vibrating piezoelectric element 80 inside the IoT smart device 10 that resonates with a specific vibration frequency to produce electrical energy, the amount of electrical energy produced may be reduced.

As such, when the amount of electrical energy is reduced, even though the target facility is operating normally, the IoT smart device 10 is stopped and the integrated management server 30 erroneously determines that the target facility is not operating. can occur

Therefore, in order to continuously check whether the facility is operating, it is necessary to check the changed vibration frequency and adjust the vibration piezoelectric element 80 in the IoT smart device 10 accordingly.
