1 is a diagram conceptually illustrating a vibration measurement system according to an embodiment.

As shown in FIG. 1, a vibration measurement system according to the present disclosure may include a vibration sensor 100 and a smartphone 200.

The vibration sensor 100 is a mechanism for measuring vibration in a location where the vibration sensor is located, and is preferably understood as a vibration sensor having a wide meaning including both a wired vibration sensor and a wireless vibration sensor.

In the case of a wired vibration sensor, since it can be continuously supplied with power from the power supply unit, it has the advantage of being able to measure vibration over a long period of time, but it cannot be measured for measurement targets over a certain distance because it is limited in the length of the connecting wire. It also exists.

In the case of the wireless vibration sensor, there is an advantage of being able to measure an object to be measured outside a certain distance, but there is also a disadvantage that long-time measurement is impossible if the battery is not supported for a long time.

The vibration sensor 100 should be fixed to the measurement object, and in the process of fixing, a magnetic sensor for fixing may be used, or a base for fixing the bond may be used. This is because an error may occur in the measured value when the fixation is not completely performed in the process of being fixed because the inherent vibration of the object to be measured must be transmitted.

The vibration sensor 100 may transmit the measured vibration information to the smartphone 200. The vibration sensor 100 may transmit vibration information to the smartphone 200 using a communication method based on a wired connection in the case of a wired connection or a wireless connection.

The smartphone 200 may receive vibration information from the vibration sensor 100. In the smart phone 200, a separate application may be installed in order to be connected to the vibration sensor 100, and a separate application is not required for connection, but a separate application may be installed to analyze vibration information.

The smartphone 200 may analyze the magnitude of the vibration and determine the cause of the vibration based on the vibration information received from the vibration sensor 100. The smartphone 200 outputs the analyzed vibration information, so that the user can recognize the result.

2 is a flowchart illustrating a vibration measurement process according to an embodiment as a time flow.

First, the user can input information on a target to measure vibration on the smartphone. The smartphone may receive information on the vibration measurement target according to the user's input (S210). For example, a user may input to measure vibration between apartment floors through an application of a smartphone, and the smartphone may be executed in a mode suitable for vibration measurement between apartments.

The smartphone may receive vibration information from the vibration sensor (S220). Vibration information may be received from a vibration sensor based on a predetermined time or a predetermined number of times, and vibration information may be periodically or aperiodically received. For example, when the vibration sensor transmits vibration information to a smartphone only when vibration occurs, the smartphone may receive vibration information and time information together.

The vibration information received from the smartphone may include some information. It may include information such as identification information of the vibration sensor, vibration measurement start time information, vibration measurement end time information, vibration size information.

In a smart phone, a specific vibration sensor may be identified among a plurality of vibration sensors through identification information of the vibration sensor, and each vibration information may be received in an identified state.

The smartphone may analyze the received vibration information (S230). In the case of vibration information having the same pattern or a similar pattern to the vibration information stored in the DB through the application of the smartphone, it can be analyzed with the identified vibration information. For example, when vibration of a specific pattern is detected in a car bonnet, it may be determined as an operating vibration of the timing chain.

Table 1 below is an example of a database (DB) analyzing the causes of vibration in life.

Cause of vibration Frequency (Hz) Acceleration size (m / s²) Car panel 13 3 Household blender 121 6.4 dryer 121 3.5 Building air conditioning system 60 0.2 ~ 1.5 Car engine 200 12 Refrigerator 240 0.1 People walking 2-3 2-3

In a smartphone, vibration information received in various ways can be processed into a single unified information. The vibration sensors may not all be the same, for example, the manufacturer itself may be a different vibration sensor, or the manufacturer may be a vibration sensor with a different detailed model even if the manufacturer is the same.

In a smartphone, vibration information received in the form of various packets can be converted into a single unified data frame format, and information of various vibration sensors can be compared and analyzed.

The smartphone may output the analyzed vibration information result (S240). For example, vibration information measured in a vehicle is a vibration of a timing chain, and it can also output whether there is a difference from a vibration of a general timing chain. A specific embodiment of outputting vibration information through a smartphone will be described later.

3 is a diagram conceptually showing a vibration measurement system according to an embodiment.

As illustrated in FIG. 3, the vibration measurement system may further include a cloud server 300 in addition to the vibration sensor 100 and the smartphone 200.

The operation of the vibration sensor 100 and the smartphone 200 has been previously described in FIG. 1 and will be omitted.

The cloud server 300 may store various vibration information. Further, the cloud server 300 may store information related to various vibration information together. For example, the vibration information having the A pattern may be engine output vibration inherent to vehicle B, and the normal range of engine output vibration inherent to vehicle B may be stored in a range of 111 to 115 Hz.

The smart phone application may determine information such as what kind of vibration and whether vibration is a normal range based on various information of the cloud server 300.

4 is a flowchart illustrating a vibration measurement process according to an embodiment as a time flow.

The smartphone may receive information on the vibration measurement target according to the user's input (S210).

The smartphone may receive vibration information from the vibration sensor (S220). Vibration information may be received from a vibration sensor based on a predetermined time or a predetermined number of times, and vibration information may be periodically or aperiodically received. For example, when the vibration sensor transmits vibration information to a smartphone only when vibration occurs, the smartphone may receive vibration information and time information together.

The smartphone may analyze the received vibration information (S230). By communicating with the cloud server through the application of the smartphone, it is possible to analyze the type of vibration information received and its cause. For example, in the case of the vibration sensor attached to the refrigerator, the fan motor component among the refrigerator components may be determined as vibration generated due to failure.

The smartphone may output the analyzed vibration information result (S240). For example, the user may indicate that the fan motor component of the refrigerator has failed and an abnormal vibration has occurred, and may be executed in conjunction with a service application such as reporting a failure.

Various vibration-related information can be output from the smartphone. For example, the vibration information currently being measured can be output to the smartphone screen in the form of a real-time graph, and can be used as a means for monitoring vibration.

The output information may be output in a form in which vibration information is processed together with time information, a trigger level is set, or reprocessed through FFT (Fast Fourier Transform) analysis. For example, in the case of outputting vibration information according to the flow of time, it is possible to change and output the time unit according to the user's setting in units of year / month / day or seconds.

The smartphone can output vibration information in various forms. As described above, it is possible to output a change based on time, and in another form, it is also possible to output vibration data from a smartphone in the form of vibration. This vibration information can also be edited and processed as one piece of information.

In a smart phone, vibration may be displayed in the form of sound, or vibration information may be output using various means that a user can recognize, such as a change in visual color.

In the smartphone, various vibration related information can be output as well as stored. The storage method can be stored as raw data or converted to sound data (MP3, WAV, etc.) and stored. The stored vibration information can be reproduced later.

5 is a block diagram conceptually showing the structure of a vibration sensor according to an embodiment.

The vibration sensor 100 according to the present disclosure may include a sensing unit 110, a communication unit 120, a power supply unit 130, and a control unit 140.

The sensing unit 110 measures vibration of a vibration measurement object. When the vibration measurement object is a fixed object, it may be fixed to be set to measure vibration. When the vibration measurement object is a moving object, vibration may be measured in consideration of the corresponding movement.

The sensing unit 110 may measure vibration for a predetermined time or a predetermined number of times. Alternatively, vibration can be measured periodically or aperiodically.

The communication unit 120 serves to transmit the measured vibration information to the smartphone. In the case of wired connection with a smartphone, various communication methods can be applied according to an interface such as a connection line, and in the case of wireless communication, various short-range communication methods such as Wi-Fi, Zigbee, and Bluetooth can be applied.

The power supply unit 130 serves to supply power to the vibration sensor. Wired power can be used to continuously supply power, or it can be attached to a battery to supply power only within a certain battery capacity.

The control unit 140 may support various functions so that the sensing unit 110, the communication unit 120, and the power unit 130 can operate normally. The control unit 140 may transmit vibration information to the smartphone only when vibration of a predetermined intensity or more is measured by the vibration sensor.

Example 1: Measurement of vibration between buildings

6 is a view for explaining measuring the vibration between the floors of a building according to an embodiment.

As illustrated in FIG. 6, vibration between floors of a building can be measured. The upper wall 600 of the lower floor 610 of the building may be subject to vibration measurement as a part that separates the upper floor 620.

A vibration sensor can be attached to the floor of the slab of the building's floor. In the case of a multi-family house, the natural frequency is often between 20 and 30 Hz, and when the vibration level in the natural frequency range exceeds a certain threshold, the inter-layer vibration alarm function is used to provide the vibration generator with information about the inter-layer vibration function. You can.

The smartphone may be connected to one or a plurality of vibration sensors 101 and 102. At this time, each vibration sensor can measure vibration and transmit the measured vibration information to a smartphone.

In a smartphone, it is possible to analyze what vibration is the vibration measured at the measurement target 600 through an application. Vibration information can be analyzed in the DB or cloud server of the smartphone application.

For example, if vibration of 2 to 3 Hz is measured by the vibration sensor 101 and vibration of 2 to 3 Hz is measured by the vibration sensor 102 after 2 to 3 seconds, the person in the upper layer 621 is walking. Can be measured.

Example 2: Automobile vibration measurement

7 is a view for explaining measuring a vehicle vibration according to an embodiment.

As shown in Fig. 7, vibrations of various parts of the vehicle can be measured. In particular, in the case of a machine that is important enough to cause danger to life when a failure occurs, such as an automobile, periodic vibration measurement and continuous management are required.

Various positions such as spring 701, transmission 702, engine 703, engine coupling 704, fuel tank 705, shock absorber 706, silencer 707, catalytic converter 708 of the vehicle You can attach a vibration sensor to the.

The smartphone can analyze vibration information at each location of the vehicle along with the model of the vehicle to be measured and year information. Because the model is different for each vehicle, the model year is different, and the usage history (driving distance) is also different, it is possible to judge the trend of the vibration change with time change rather than having the same DB.

The smartphone may be connected to a cloud server to search for the same or similar vibration measurement information based on the target information of the vehicle, such as year information, model information, and usage history.

For example, if vibration information of 215 Hz and a specific pattern is measured for a vehicle, and vibration measured for another identical model same-year vehicle is vibration information having a similar pattern at 230 Hz, the two vehicles are in a similar state (for example, Both are normal).

Such information may be continuously stored and managed by the cloud server, and the measurement result information of users may be stored and managed as one or more DBs.

Example 3: Other vibration measurement

When a construction site is located in the vicinity, harmful substances spread from the construction site, and information such as noise or vibration is generated in addition to the harmful substances. The user can measure the vibration of the construction site at a certain distance from the construction site, and determine whether the construction site complies with the legal standards for the construction environment according to the measured vibration information.

Vibration regulations at the construction site can be checked on a smartphone through a DB, and in some cases, if the regulations are not observed at the construction site, the application can be supported by the smartphone application up to the step of reporting to the relevant institution.

In addition, by measuring vibrations of various machines, it is possible to diagnose machine failures or perform machine maintenance. For example, in a smartphone application, it is possible to determine whether a malfunction is caused by a vibration sensor attached to a household appliance such as a refrigerator or a home desktop, a water pipe, a facility such as a hot water pipe, or a large equipment such as an elevator.

In addition, information about large vibrations such as earthquakes or traffic flows can be collected from a vibration sensor attached at all times. Through the vibration sensor attached to the road, it is possible to measure the safety state of the road or diagnose the safety state of the bridge.

The vibration measurement information is displayed in the form of one piece of information, and can be used as a diagnosis of failure or evidence of interlayer noise (vibration).
