Description

Technical Field [0001] The present invention relates to an equipment abnormality diagnosis apparatus using an inclination sensor and an abnormality diagnosis system using the same,

The present invention relates to an equipment abnormality diagnosis apparatus using an inclination sensor and an abnormality diagnosis system using the same. More particularly, the present invention relates to an equipment abnormality diagnosis apparatus using a tilt sensor, The present invention relates to an equipment abnormality diagnosis apparatus using a tilt sensor for comparing a vehicle with a reference signal to determine whether or not the equipment is abnormal, and an abnormality diagnosis system using the same.

The failure of the equipment is inevitably accompanied by changes in output, abnormal rise in temperature, and noise and vibration. These changes appear before the facility has reached an inoperative state. Therefore, it is possible to diagnose facilities without stopping the operation by appropriately monitoring the abnormal symptoms of the facility in advance.

Through the diagnosis of such facilities, it is possible to use facilities and parts safely until the end of life, and to save maintenance cost and material cost. In addition, since the facility is diagnosed while the facility is operating, it is possible to improve the operation rate by reducing the stopping time of the facility.

Particularly, in a facility having a rotating body such as a turbine or a power plant equipped with a generator, vibration corresponding to the number of rotations of the rotating body is generated. And in such a facility, the abnormality of the device necessarily changes the pattern of vibration. Therefore, by constantly monitoring and monitoring the vibration of the equipment, it is possible to diagnose the abnormality of the equipment in advance.

Vibration often has a factor of amplitude and frequency, and it is possible to monitor the amplitude and frequency of the three-dimensional coordinate system, respectively. The vibration measurement method for the fault diagnosis of a facility usually measures the acceleration of the facility. An acceleration sensor is attached to the facility to measure the acceleration of the facility during operation. When the acceleration is greater than the reference acceleration value, it is determined that an abnormality has occurred in the facility.

Since a typical acceleration sensor has a three-dimensional coordinate system for the acceleration sensor body, it is necessary to perform an operation of calibrating an absolute reference point or an absolute coordinate in the facility and a coordinate system of the acceleration sensor itself, when the position and posture of the installed acceleration sensor are changed . In addition, as long as such alignment is achieved, the coordinate system of the acceleration sensor installed on the facility is immediately broken in terms of the absolute reference point or the absolute coordinates in the facility if the posture of the equipment itself is slightly changed or changed due to continuous vibration . Therefore, even if an acceleration sensor is installed at a specific point on the actual facility to align the three-dimensional coordinate system, there is a possibility that the absolute coordinate or the absolute coordinate is misaligned. Therefore, The frequency or amplitude will not correspond to the absolute reference point or the absolute coordinate, and strictly speaking, the reliable value of the measurement value of the acceleration sensor is the numerical value of the directional frequency and amplitude.

However, the actual operation of the equipment may cause the posture of the equipment to deviate from the initial posture due to the abnormal operation, and the posture may be changed due to the deformation at some points due to the impact applied to the equipment. Therefore, when the acceleration sensor is installed and only the acceleration value of the facility in operation is measured, only the acceleration value at the point where the accelerometer is attached can be reliably utilized, and information about the change of the posture of the facility or the variation of the facility can be grasped I can not. Such fragmented information is insufficient for diagnosing the abnormality of the facility in advance. Therefore, in order to diagnose the abnormality of the facility, it is necessary to measure the posture and deformation of the facility while continuously monitoring the vibration of the facility, and to implement a more accurate diagnosis of the facility based on the measurement.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

It is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to inform.

The tilt sensor is a sensor that measures the angle of an object with respect to gravity. Recently, MEMS tilt sensors, which provide excellent price / performance due to development of microelectromechanical systems (MEMS) technology, are widely used. Capacitive MEMS tilt sensors, commonly used in the field, consist of a fixed electrode and a flow electrode attached to a standard mass connected by a spring. When the tilt sensor is horizontal, the capacitance formed between the electrodes is measured. When the tilt sensor is tilted, the position of the flow electrode changes with respect to the fixed electrode, and the changed capacitance between the two electrodes is measured. The capacitive MEMS tilt sensor thus measures the tilt change from the change in capacitance.

The present invention relates to an equipment abnormality diagnosis apparatus using a tilt sensor and an abnormality diagnosis system using the same. 1 is a block diagram of a first embodiment of an apparatus malfunction diagnostic apparatus according to the present invention.

The equipment abnormality diagnosis apparatus of the present invention comprises two or more tilt sensors mounted on a predetermined portion of a facility to be diagnosed to measure a tilt of a mounting point; An A / D converter for converting an analog output signal of the sensor into a digital signal; A pairing module for forming a sensor combination with two selectable sensors among the two or more tilt sensors and an attitude measuring module for calculating a difference between tilt signals from the two tilt sensors constituting each combination of sensors, And an abnormality diagnosis module that compares the difference between the slope signals of the sensor combinations with the reference signal to determine whether or not the equipment is abnormal. And a wireless transmitter for transmitting measurement data of the microprocessor to an external device.

Since the output of the tilt sensor is an analog signal, it is converted into a digital signal using an A / D converter for digital control. The tilt sensor measures the angle at which the sensor is installed on the horizontal plane. The tilt sensor is attached to a plurality of locations that are of interest for the safety of the facility to be diagnosed. The tilt sensor can output the slope of the gravity direction as an electrical signal, and when the vibration occurs at the attached facility location of the diagnosis target, it outputs an electrical signal following the slope changed by the vibration. Therefore, when a change in the slope occurs due to the occurrence of the vibration, the frequency and the amplitude can be calculated based on the change period and the change amount of the slope.

For example, when the maximum and minimum values of the tilt appear 30 times per second, it can be seen that a vibration having a frequency of 30 Hz has occurred. When the amount of shaking of the tilt in the x-axis and the tilt in the y- The amplitude can be calculated from the amount of oscillation generated corresponding to the center slope value of the oscillation amount. Such calculation of the amplitude can be performed through mapping data obtained by converting the center slope value of the amount of oscillation and the amount of oscillation generated at that time into an amplitude. For example, when the center slope is 7 ° and the amount of swing is ± 1 ° and when the center slope is 45 °, when the swing amount is ± 1 °, the actual amplitude of the vibration may be different. However, The calculated amplitude can be calculated by using the converted mapping data. Therefore, according to the present invention, it is possible to measure the vibration of the facility by using the tilt sensor.

In addition, the present invention can monitor the posture of the facility using the tilt sensor. The above-described pairing module selects two sensors among a plurality of tilt sensors attached to the facility to form a sensor combination. When a plurality of sensor combinations are formed through the pairing module, the tilt difference in each sensor combination can be monitored according to the change of the time, and the change in attitude of each part of the facility can be grasped.

The attitude measurement module measures the attitude of the facility by calculating the difference between the tilt signals from the two tilt sensors constituting each sensor combination. The difference in the angle measured by the two tilt sensors is stored as time elapses, and monitoring of the change can be used to grasp the change in the attitude of the facility.

For example, when the tilt sensor at the initial position of the A-position tilt sensor is 5 ° and the tilt sensor at the initial position of the B-tilt sensor is 10 °, If the tilt of the tilt sensor at the initial installation is 9 °, the difference of the tilt between the two positions after the two tilt sensors are paired is 4.5 ° It can be confirmed that the relative posture of the A position and the B position of the facility has been changed.

The fault diagnosis module compares the difference between the slope signals of each sensor combination with a predetermined reference signal to determine whether or not the equipment is abnormal. The reference signal is selected based on the attitude determined to be dangerous for the safety of the equipment.

For example, the relative attitude between the A position and the B position should be 4.7 ~ 5.3˚, which is safe on the equipment basis. If the slope difference between the two positions is 4.5˚, it can be judged that an abnormality has occurred in the equipment. The data output from the microprocessor is transmitted to a portable terminal, a smart phone, a wireless repeater, and a server computer through a wireless transmitter. The wireless transmitter can use one or more suitable methods for various types of short-range communication modules such as RF, WiFi, Bluetooth, NFC, and Zigbee. Although the wireless transmitter is illustrated in the embodiment of the present invention, the transmitter is not necessarily configured wirelessly. The apparatus abnormality diagnosis apparatus according to the present invention may further include a storage unit. The storage unit can efficiently manage the memory by storing the output value of the microprocessor only when it is determined that the facility is unsafe by the abnormality diagnosis module. In addition, if the memory is full, data can be continuously recorded by overwriting old information.

The tilt sensor, the A / D converter, the microprocessor, and the wireless transmitter may be configured to implement the measurement apparatus. Therefore, when such an individual measuring apparatus is installed at a facility site where measurement is required, a measurement signal for a tilt output from the tilt sensor is processed and calculated by the microprocessor as vibration information, and information about the vibration is transmitted to an external apparatus Lt; / RTI > Further, the measuring apparatus may further include a storage unit, and the data of the vibration information may be separately stored in the storage unit.

The abnormality diagnosis unit including the above-described pairing module, the attitude measurement module, and the abnormality diagnosis module may be a function embedded in the microprocessor. That is, it is possible to implement the above-described functions in the microprocessor of each measuring instrument. Alternatively, the functions of the pairing module, the attitude measuring module, and the abnormality diagnosis module may be implemented in an external device, for example, a server computer. In particular, when dozens to dozens of measuring devices are monitored by a single server computer, duplicate implementations of the same functions can be minimized when implementing them in a server computer. Therefore, if the abnormality diagnosis unit is implemented in the microprocessor, the measurement apparatus and the abnormality diagnosis apparatus may refer to the same apparatus. If the abnormality diagnosis unit is implemented in the server computer, .

The measuring device is waterproof and is equipped with a rotary external antenna so that it can be easily installed in the installation position so that wireless transmission is best. By placing such a measuring device near the rotation cause of vibration, the vibration can be measured more precisely. When configuring the measurement device wirelessly, it is possible to supply power using a rechargeable or disposable battery, and it is desirable to guarantee the service life for 6 months or longer by charging or replacing one battery.

The measurement period of the tilt sensor included in the measuring apparatus is adjustable based on 100 msec, which can be determined in consideration of the number of revolutions of the oscillation source.

FIG. 2 is a block diagram of a second embodiment of the apparatus abnormality diagnosis apparatus according to the present invention. The second embodiment further includes at least one acceleration sensor mounted on a predetermined portion of the facility to be diagnosed to measure the acceleration of the mounting point.

In the second embodiment, in measuring the vibration generated in the equipment, not only the tilt sensor but also the acceleration sensor may be used. That is, the tilt sensor provides a tilt signal for measuring vibration and attitude, and the acceleration sensor provides an acceleration signal for measuring vibration.

Such an acceleration sensor can be utilized in various ways. For example, a tilt sensor may be used to measure the attitude of the facility, and an acceleration sensor may be used to measure the vibration of the facility. This is implemented so that the tilt sensor and the acceleration sensor do not measure vibration due to overlapping.

Next, the information about the vibration can be calculated on the basis of both the tilt signal of the tilt sensor and the acceleration signal of the acceleration sensor. That is, the microprocessor can combine the tilt signal and the acceleration signal to calculate information about the vibration corresponding thereto.

Next, the information about the vibration is calculated based on the tilt signal of the tilt sensor, the information about the vibration calculated based on the acceleration signal of the acceleration sensor is calculated, and the two calculated values are compared / The vibration of the facility can be monitored by confirming the information about the vibration while confirming the measurement accuracy of the facility.

In other words, the present invention encompasses the use of the acceleration sensor as a vibration measuring means, mainly or as an auxiliary, without unconditionally eliminating or omitting the acceleration sensor because the vibration sensor can measure the vibration using the tilt sensor.

The fault diagnosis module compares the difference and the acceleration of the tilt signals with the respective reference signals to determine whether or not the equipment is abnormal. The operator can comprehensively judge the condition of the facility based on the degree of vibration and the degree of attitude change.

The tilt sensor, the acceleration sensor, the A / D converter, the microprocessor, and the wireless transmitter may constitute the measurement apparatus.

3 is a block diagram of a third embodiment of the apparatus abnormality diagnosis apparatus according to the present invention. The third embodiment includes a temperature sensor mounted on a predetermined portion of a facility to be diagnosed to measure the temperature of the mounting point and a temperature correction device for temperature measurement of the measured values of the tilt sensor and the acceleration sensor based on the temperature signal measured by the temperature sensor And a temperature correction module for performing the temperature correction.

The temperature sensor continuously measures the temperature of the facility and outputs the signal. The cause of the vibration is usually the rotating body in the facility, and the frictional force generated as the rotating body rotates is dissipated into heat. However, such heat is generally generated in proportion to the degree of vibration. Therefore, if the temperature near the vibration source can be measured, it is possible to indirectly confirm whether or not the vibration source (for example, the rotating body) is overheated through the measured temperature. Therefore, if the measured temperature rises above the preset reference temperature, the overheating pattern can be confirmed. Such a facility may be overheated due to vibration, abnormal operation, etc., or the temperature may rise due to environmental factors.

At this time, various sensors (acceleration sensor, tilt sensor, etc.) can be in an environment outside the normal operating temperature range, and measurement error occurs in the data measured in the range beyond the normal operating temperature range. Therefore, the temperature sensor can be used as a basis for accurately measuring the temperature of the facility and performing temperature compensation on the measured value of the sensor. To this end, the present invention is configured such that the output signals of the tilt sensor and the acceleration sensor are corrected by the temperature correction module. That is, the temperature correction module corrects the output signal measured by the tilt sensor and the acceleration sensor based on the temperature measured by the temperature sensor.

When the measuring device is installed near the rotating cause of the vibration, it is possible to detect the temperature change of the rotating body as well as the measurement of the vibration, so that the overheating of the rotating body can be confirmed indirectly but reliably.

It goes without saying that the tilt sensor, the acceleration sensor, the temperature sensor, the A / D converter, the microprocessor, and the wireless transmitter may constitute the measurement device.

The measuring apparatuses of FIGS. 1 to 3 may be used at the same time. It is preferable that the measuring apparatuses are distinguished from each other by assigning different IDs to each measuring apparatus. In order to attach the measuring apparatus to the measuring position, Method or the like can be used.

4 is a block diagram of an embodiment of a portable terminal according to the present invention. If the above-described measuring apparatus is operated in a state where it is installed in a predetermined measurement position of the facility, the portable terminal shown in FIG. 4 can be installed and installed at a required position while being carried by an operator, There is a difference.

Such a portable terminal not only includes a wireless transmitter, but also includes a wireless receiver for receiving data wirelessly as compared with the above-described measuring apparatus. The portable terminal can receive data of the measurement device via the wireless receiver. Since the portable terminal has the display, it is possible to display the data received from the measuring device on the display. Of course, data measured by the portable terminal itself can also be displayed on the display.

It is preferable that the portable terminals are also individually given IDs, and when inputting the measurement, it is preferable to include an input unit for inputting the measurement position. Such an input may be a touch screen formed on the display.

5 is a block diagram of a first embodiment of the system fault diagnosis system according to the present invention.

As described above, the abnormality diagnosis unit may be provided in the microprocessor and / or the server computer.

The measuring device transmits measurement data to the portable terminal and the server computer using wireless communication. The measurement data transmitted by the measuring device is transmitted to the field worker, and if the received measurement data is in a dangerous situation, the operator in the field can immediately access the abnormal facility and take an immediate action. The portable terminal transmits the measurement data of the facility measured by the field operator to the server computer. In addition to the schemes shown in the figures, it is possible to communicate with various other protocols.

When the field worker lifts the portable terminal, the measuring device and the portable terminal are connected to each other, the data of the measuring device can be transmitted to the portable terminal, the operator can confirm the display of the portable terminal, By checking the measurement data of the measuring device installation position, it is possible to grasp the abnormality of the equipment conveniently and intuitively in the field.

The apparatus abnormality diagnosis system according to the present invention includes a measurement device, a smart phone for receiving and displaying measurement data from the measurement device, a server computer for storing and managing abnormality diagnosis data of the facility, .

In addition, the smartphone can transmit the measurement data of the received facility to the server computer so as to prepare for data transmission errors due to communication abnormality between the measurement device and the server computer.

The portable terminal or the smartphone described above can simultaneously receive data from a plurality of measurement devices and simultaneously display the same.
