In addition, the malfunction diagnostic device may have a vibration detection unit and vibration analysis data according to the vibration range generated at the installed position. The malfunction detection device may be applied to any object that generates a vibration inherent in the operation, such as a machine, a device, a facility, a structure, a fixed structure, or a moving structure. The malfunction diagnosis device 10 of the self-driving type vibration detection according to the present invention includes the diagnostic housing 11 in which the operation module 14 is disposed and the vibration analysis module for analyzing the vibration detected by the vibration detection unit, ; A mounting block (13) disposed below the diagnostic housing (11) and provided with at least one fixing tab (16); A control unit (31) disposed inside the diagnostic housing (11); A light emitting unit 151 which emits light under the control of the control unit 31; A memory (M) for storing the vibration data detected by the vibration analysis detection unit or the result data analyzed by the vibration analysis module; A battery module disposed inside the diagnostic housing (11); And a mode switching unit (321) for switching an operation mode when abnormal vibration is detected, and the operation of the vibration detection module is set by the operation module (14) in a sleep mode or an operation mode.

The diagnostic housing 11 can be made of a variety of materials for stainless steel, synthetic resin or an outer casing in this field.

The vibration detection unit disposed inside the diagnostic housing 11 may be, for example, an acceleration sensor or an optical fiber sensor, and may be made in the form of a MEMS element. The vibration detection unit may be any vibration sensor capable of detecting various vibrations transmitted through the mounting block 13 or the fixing tab 16. [ The vibration detected by the vibration detection unit may be transmitted to the vibration analysis module, and the vibration detected by the vibration analysis module may be analyzed to determine whether it is malfunctioning. A control unit including a microprocessor for controlling the entire operation inside the diagnostic housing 11 can be disposed and the battery module can be housed in the diagnostic housing 11. [ Such a diagnostic housing 11 can function as one independent diagnostic system. And the operation module 14 may be disposed outside the diagnostic housing 11. [

The operating module 14 may include a screen 141 and a set button 142 and the screen 14 may be any display means known in the art. The screen 141 may be a touch type according to the design structure. The setting button 142 may include an operation display button, an operation status display button, or a mode setting button.

The mode setting button may have the function of switching the operation mode of the diagnostic device from the sleep mode to the operation mode or vice versa.

The malfunction diagnostic device 10 according to the present invention can be operated in the sleep mode and only the functions determined in the sleep mode can be activated. For example, in the sleep mode, only the abnormal vibration detection function that detects the occurrence of vibration above a certain size can be operated. The mode setting button can be operated to change from the sleep mode to the operating mode. Or a mode may be automatically changed when a predetermined time, an amplitude equal to or larger than a predetermined amplitude, or a vibration in a predetermined frequency band is detected. The predetermined time means the time determined in the measurement schedule. The measurement schedule corresponds to the data for determining the time at which the vibration is measured, and when the time is determined by the measurement schedule, the malfunction diagnostic device 10 can be switched from the inactive state corresponding to the sleep mode to the active state. Then, the vibration is measured by the vibration detecting unit for a predetermined time and can be switched to the sleep mode again. In such a sleep mode, it is possible to switch to the operation mode if a vibration having an amplitude of a predetermined magnitude or more is generated, a vibration in a predetermined range of frequency bands is measured, or a vibration is not generated at regular intervals. And analyze the state in which the generated vibration or vibration is not measured, and operate the light emitting unit 151 according to the control of the control unit.

A control board 15 such as a printed circuit board may be disposed on the upper portion of the diagnosis housing 11 and a light emitting unit 151 may be disposed on the control board 15. [ The control board 15 may be disposed above the diagnostic housing 11 by a fixed unit 152 and may be connected to a power source such as a battery disposed internally by the electrode tab T. The light emitting unit 151 may be, for example, an LED module, and may be protected by a protective cap 12 made of a transparent material. The protective cap 12 can be made of a synthetic resin material and can be made detachable from the diagnostic housing 11. The protective cap 12 may have an induction structure (LD) capable of guiding light emitted from the light emitting unit 151 to a predetermined path. The guide structure LD may be formed to guide a part of light emitted from the light emitting unit 151 to a predetermined position, and may include a lens module such as a concave lens or a convex lens.

The control board 15 can be made detachable from the diagnostic housing 11 and can be electrically connected to the battery module disposed inside the diagnostic housing 11 by the electrode tab T. [ In this way, the protective cap 12 and the control board 15 are made detachable from the diagnostic housing 11 so that the malfunction diagnostic device 10 can be easily applied to different devices. Unique vibrations of different frequency bands may be generated in different apparatuses and different abnormal vibrations may be generated. In this case, the different control boards 15 can be coupled to the same diagnostic housing 11 while the control boards 15 are manufactured differently or the settings of the control units disposed on the control board 15 are made different from each other.

The mounting block 13 can be in the form of a circular cylinder and can be made of a rigid material. At least one fixing tab 16 may be formed on the mounting block 13 and the fixing tab 16 has a function of fixing the malfunction diagnostic device 10 to a machine or apparatus to be diagnosed. Specifically, the diagnosis object may have various shapes, and the base block may be disposed at the installation position of the malfunction diagnostic device 10. [ The base block can be made of a suitable structure in contact with the surface shape of the subject to be diagnosed, and can have a fixing hole to which the fixing tabs 16 are coupled. The malfunction diagnostic device 10 can be installed on the diagnosis object by engaging the fixing tabs 16 with the fixing holes. At least a part of the base block may be made of a magnetic material and at least a part of the mounting block 13 or the fixing tab 16 may be made of a magnetic material.

The malfunction diagnostic device 10 can be fixed to a diagnostic object in various ways, and the present invention is not limited to the embodiments shown.

A battery module may be disposed inside the diagnostic housing 11, and the battery module may include a rechargeable battery. And the battery module can receive some power required for operation from the power generation module.

Fig. 2 shows an embodiment of a self-charging module applied to a diagnostic device according to the invention.

Referring to FIG. 2, the self-charging module 20 is connected to the battery module and includes a vibration transmission element 24 and a solar cell 23. The self-charging module 20 can be made of a module independent of the diagnostic housing 11 described above, and can be disposed at a position adjacent to the diagnostic housing 11. [ The self-charging module (20) includes a vibrating block (22) secured to the structure; A cell fixing block 21 disposed above the vibration block 22; A solar cell 23 installed in the cell fixing block 21; A vibration transmission element 24 for transmitting the vibration generated in the structure or the vibration block 22 to the power conversion unit; And an electrode connection tab 25 that is electrically connected to the battery module disposed in the diagnostic housing 11.

The vibration block 22 can be made into a structure suited to the shape of the structure, and a conversion unit for converting vibration into electric power can be disposed inside. The vibration block 22 may be made of a resonance structure that amplifies vibration generated while transmitting vibration generated from the structure. Specifically, the regular natural vibration generated in the structure is determined, and the vibration block 22 can be made into a structure resonating with the natural vibration. The cell fixing block 21 may be made of a vibration absorbing material that is disposed above the vibration block 22 and absorbs vibration generated in the vibration block 22. [ For example, the cell fixation block 21 may comprise a foam material or a layer of sponge material, thereby preventing the vibrations generated in the vibration block 22 from being transmitted to the solar cell 23. The solar cell 23 can be disposed above the cell fixing block 21. [ At least one vibration transmission element 24 may be disposed under the vibration block 22. [ The vibration transmission element 24 may be disposed in a cylindrical hole formed in the vibration block 22 and may be made of a material having a frequency that resonates with the natural vibration of the fixture. The vibration generated in the vibration transmission element 24 can be transferred to a conversion element such as a piezoelectric element and converted into electric energy. Such an energy conversion unit can be made of a MEMS structure. The converted power may then be transmitted to the battery module via the electrode connection tab 25. [

The solar cell 23 can be any structure known in the art and the power generated by the solar cell 23 can also be transmitted to the battery module via the electrode connection tab 25. [ The solar cell 23 can be operated according to the external condition condition.

A self-charging module 20 having various structures can be applied to the present invention, and the present invention is not limited to the embodiments shown.

Fig. 3 shows an embodiment of the operating structure of the diagnostic device according to the present invention.

Referring to Fig. 3, the operation of the malfunction diagnostic device can be controlled by the control unit 31. Fig. When a diagnostic object to be installed with the diagnostic device is determined, a measurement schedule can be created by the measurement schedule unit (MT) according to the characteristics of the diagnostic object. The vibration detection period of the malfunction diagnostic device can be determined by the measurement schedule. The vibration detection cycle can be determined according to the characteristics of the diagnosis object, and the measurement schedule can be transmitted to the control unit 31 and stored. And the operation of the malfunction diagnostic device by the operation module 14 can be set. The malfunction diagnostic device can be operated according to the set conditions. When the operation is started, vibration can be detected by the vibration detection unit 32 according to the measurement schedule. When the vibration is detected by the vibration detection unit 32, the mode switching unit 321 can switch to the sleep mode. And the abnormal vibration detection unit 322 can be operated. The abnormal vibration detection unit 322 can be connected to the mode switching unit 321 and can have vibration data to be generated in the abnormal condition of the diagnosis target or vibration data that can be generated in the surrounding environment, . And a reaction switch circuit with reaction conditions for such vibration. For example, when natural vibration having a predetermined range of amplitude is transmitted to the reaction switch circuit, the reaction switch circuit causes the mode switching unit 321 to remain in the sleep mode. On the other hand, the reaction switch circuit can operate the mode switching unit 321 when the vibration is out of the predetermined range, the vibration having the unexpected frequency, or the natural vibration is not transmitted for a predetermined time. Then, the mode switching unit 321 can transmit a situation in which the malfunction diagnostic device is switched from the sleep mode to the operation mode, vibration is transmitted to the vibration detection unit 32, or is not vibrated. The mode switching unit 321 can increase the operation period of the malfunction diagnostic device itself, which is operated without supply of external power, while accurately detecting the change in the operating state of the diagnostic object over time.

The vibration detected periodically or by the operation of the abnormal vibration detection unit 322 can be transmitted to the vibration isolation unit 331 and the vibration analysis unit 332. [ The vibration separated according to the frequency band by the vibration isolation unit 331 can be filtered by the vibration analysis unit 332. [ The vibration analysis unit 332 may remove frequency bands having, for example, natural frequencies or predictable vibrations or minute amplitudes depending on the external environment. And transmit the vibration to the comparator 342 in a frequency band for which analysis is required. The comparator 342 may compare the vibration of each transmitted frequency band with the vibration data stored in the analysis database 341. [ The analysis database 341 is a database for analyzing the vibration of the frequency band that can be generated according to the malfunction of the diagnosis object, the vibration of the frequency band having the amplitude capable of damaging the diagnosis object, And may have vibration data about the vibration. The comparison result by the comparator 342 can be transmitted to the risk level unit 35 and the risk level unit 35 can determine the risk level for the diagnostic subject according to the comparison result sent from the comparator 342. [ And whether or not the light emitting unit 151 emits light can be determined according to the risk level determined by the risk level unit 35. [

The risk level unit 35 may send the risk level to the schedule confirmation unit 36 and the schedule confirmation unit 36 may change the measurement schedule according to the risk level and the changed measurement schedule may be transmitted to the measurement schedule unit MT, Lt; / RTI > And the operation of the malfunction diagnostic device can be set by the operation module 14 according to the changed measurement schedule.

The vibration detected by the vibration detection unit 32 at each measurement time can be stored in the memory M. [ The measurement time of the detection vibration stored in the memory M and stored in the memory M can be transmitted to the schedule confirmation unit 36 at the same time. The schedule confirmation unit 36 can transmit the storage time of the memory M to the measurement schedule unit MT and the measurement schedule unit MT can calculate the error of the measurement time and adjust the measurement schedule accordingly.

The detected vibration data stored in the memory M or the risk level determined by the risk level unit 35 can be transmitted to the outside by the transfer unit 37. [ The transmission can be done by a management server, for example, in a short distance communication such as Bluetooth or a long distance wireless communication. The detected vibration data stored in the memory M can also be transmitted to the electronic device through an appropriate connection port.

The malfunction diagnostic device according to the present invention may include various components or elements for malfunction detection, and the present invention is not limited to the embodiments shown.

Figure 4 shows an embodiment of the operating structure of a self-charging module connected to a diagnostic device according to the invention.

Referring to FIG. 4, the self-charging module 20 can produce self-power from the vibration transmission element 24 and the solar cell 23. The vibration transmission element 24 may include at least one piezoelectric element for generating an electromotive force from, for example, vibration generated in the structure. The vibration transmission element 24 or the solar cell 23 may be connected to the conversion unit 41 which converts the voltage to a proper voltage by the connection setting unit 411. [ The operating state of the malfunction diagnostic device can be detected by the mode detection unit 42 and the power generated according to the operating state or the charging state detected by the charging detection unit 45 is supplied to the battery 44 Or may be supplied to the battery 43. The state of charge of the battery 44 can be detected by the charge detection unit 45 and the charge circuit 46 can be activated and the battery 44 can be charged by the battery 43 .

The self-charging module 20 can be made in various configurations, and the present invention is not limited to the embodiments shown.

FIG. 5 illustrates an example of a process of diagnosing a malfunction by the diagnostic device according to the present invention.

Referring to FIG. 5, a method of diagnosing a malfunction of a machine, an apparatus, or a facility by vibration detection includes: (P51) setting a vibration detection process based on a natural vibration frequency band of a machine, an apparatus, or a facility; Determining a measurement schedule and determining an operation time according to an operation mode and a sleep mode (P52); Detecting vibration according to the measurement schedule (P53); Analyzing the detected vibration (P54); Comparing the analyzed vibration with preset vibration data (P55); Determining whether there is abnormal vibration according to amplitude or frequency band (P551); Determining a risk level when abnormal vibration is detected (P56); Changing the measurement schedule according to the risk level (P57); A step (P58) of controlling the light emitting unit to emit light according to the danger level; And storing the detected vibration, the analyzed vibration or the risk level in a memory and transmitting to the predetermined electronic equipment as needed (P59).

The diagnostic method according to the present invention can detect and analyze regular or irregular vibration occurring in a machine, facility, apparatus or structure, and can be applied to diagnosis of a malfunction state or an abnormal state of the structure based on the analysis. Regular vibration can be diagnosed periodically, and irregular diagnoses can be detected and diagnosed at the same time as they occur. For example, a reaction switch circuit that operates the vibration detection unit in the sleep mode in response to irregular vibrations. The diagnostic method according to the present invention can be applied to various fixing devices or mobile devices using the portable malfunction diagnosis device described above, and can also be applied to a fixed structure.

An operation procedure for vibration detection can be set (P51), and a sleep mode and an operation mode can be set (P52). For example, in the operating mode, it may periodically detect the natural vibration of the machine or device and remain in the sleep mode again. In the sleep mode, when the malfunction diagnostic device is not supplied with power and is forcibly switched to operation or an irregular vibration is generated, the power supply can be started while the mode is switched to the operation mode. In the sleep mode, the self-charging module can be operated and the malfunction diagnostic device can be kept in the minimum power consumption state. The operation mode is switched according to the measurement schedule, and natural vibration can be detected. Or irregular vibration may be generated and the vibration can be detected by the vibration detection unit (P53). And the detected vibration can be analyzed (P54). The vibration detected by the comparator can be compared with the preset vibration. The predetermined vibration may be, for example, natural vibration of the device or machine or similar vibration. Whether or not abnormal vibration has occurred can be determined according to the comparison result (P551). If it is determined that abnormal vibration does not occur (NO), vibration detection may be performed according to the measurement schedule (P53). On the other hand, if it is judged that abnormal vibration has occurred (YES), the risk level can be determined according to the analysis result (P56). And the measurement schedule can be changed according to the risk level (P57). The change in the measurement schedule means that the measurement period is changed in such a manner that the measurement period is shortened according to the risk of the vibration level or is continuously measured for a predetermined time. Thereafter, the higher the risk level, the shorter the measurement period and the greater the number of measurements. If the risk level is low, the measurement schedule may change again (P57).

The light emitting unit can be lighted by the control unit according to the danger level (P58), and the voice alarm unit can be operated according to the installation position of the malfunction diagnostic device if necessary. And a dangerous situation can be transmitted to an electronic device such as a manager's smart phone using a communication means. The detected vibration and analysis results can then be stored in memory and periodically transmitted to the management server (P59). Alternatively, the malfunction diagnostic device may be provided with a transmission port such as a USB port, whereby various data stored in the malfunction diagnostic device or detected vibration may be transmitted to the electronic device or the management server.

The malfunction diagnostic device can be operated in various ways, and the present invention is not limited to the embodiments shown.
