Description

FUSION SENSOR MODULE FOR GASPIPE CONDITION MONITORING AND FUSION SENSOR SYSTEM USING THE SAME AND CONTROL METHOD USING THEREOF}

The present invention relates to a fusion sensor module for monitoring gas pipe condition, a fusion sensor system including the same, and a control method using the same.

The gas used in our lives is generally divided into two categories. Liquified Petroleum Gas (LPG) liquefied at high pressure at room temperature, mainly composed of propane gas or butane gas with relatively low boiling point, and liquefied natural gas liquefied gas of methane component obtained by refining natural gas (Liquified Natural Gas; LNG).

On the other hand, liquefied natural gas (LNG) is used by passing through the pipe from the production site or processing site to the gas use site. There is a possibility that the gas pipe may be damaged due to an impact from the outside while the gas flows inside the gas pipe to the gas place. If there is no early detection of possible damage to the gas line, there is a risk of gas leaks and explosions.

In order to detect such gas leakage and explosion risk early, a sensor was attached to the outside of the pipe to monitor the gas pipe for abnormality. Various types of sensors can be used to monitor gas pipes for abnormality, and each sensor is attached to the gas pipe to perform sensing, which is inefficient in terms of sensing efficiency and cost. In addition, when the sensor is attached to each gas pipe and sensed, it is difficult to immediately detect deformation or breakage of the gas pipe due to sudden construction work or external load, and thus it is not possible to quickly sense whether the gas pipe is abnormal.

The micro vibration sensor 130 is for measuring the micro vibration in a smaller range than the vibration sensor 120, the micro vibration sensor 130 may be a sensor using a piezoelectric element. However, the present invention is not limited thereto, and any type of micro vibration sensor 130 capable of sensing a micro vibration value of the inspection pipe P may be selected and used. The fine vibration sensor 130 has a fine sensing range, unlike the acceleration sensor 110 and the vibration sensor 120 disposed on the printed circuit board 160 constituting the fusion sensor 100. 160 may be connected to the cable 150, and the printed circuit board 160 may be spaced apart from each other at regular intervals. The micro vibration sensor 130 using the piezoelectric element is formed to be spaced apart by a predetermined interval while being connected to the printed circuit board 160 and the cable 150, the vibration that can occur from the printed circuit board 160 is fine vibration sensor 130 There is an advantage of minimizing the impact of sensing.

On the other hand, the above-described sensors are exemplary, additional sensors that can sense the deformation or damage of the inspection pipe, such as temperature sensor may be further included in the fusion sensor (100). As the sensors are integrated into the fusion sensor 100 as described above, each sensor is installed in the inspection pipe P, and thus, there is an advantage that efficient monitoring can be performed as compared with the sensing.

3 is a perspective view of a fusion sensor module 10 according to an embodiment of the present invention. Referring to FIG. 3, the fusion sensor 100 is accommodated in the housing 140 to cover all directions. The housing 140 may be formed in a rectangular parallelepiped shape, but is not limited thereto, and may have any shape that can accommodate the fusion sensor 100.

In addition, the fusion sensor 100 and the housing 140 may be molded using an epoxy material. By molding between the fusion sensor 100 and the housing 140 with an epoxy material, the fusion sensor 100 has an advantage of preventing the contaminants from penetrating without shaking inside the housing 140. In addition, by insulating the fusion sensor 100 through an epoxy molding, it is possible to prevent malfunction due to a short circuit, and by lowering the center of gravity of the fusion sensor 100, the fusion sensor 100 is stably installed without tilting to one side. There is an advantage that can be.

On the other hand, between the fusion sensor 100 and the inspection pipe (P) is a mounting portion 200 is formed to cover a portion of the outer peripheral surface of the inspection pipe (P). The mounting part 200 may include a plurality of plates 210 having a rectangular parallelepiped shape. The plurality of plates 210 may be formed of a material having strong dimensional stability, stability, and impact resistance, and thus the plurality of plates 210 may be formed of POM (polyacetal) material. By forming a plurality of plates 210 made of POM material, there is an advantage that can cover a part of the outer circumferential surface of the inspection pipe (P) stably even in the external environment changes.

In addition, the plurality of plates 210 are connected to each other by a foldable connecting member 220 to one side. The connection member 220 may connect adjacent plates 210 in the form of a hinge, and thus, the plurality of plates 210 and the connection member 220 are coupled to each other to form one mounting portion 200. Since the mounting part 200 is bent by the connection member 220, the mounting part 200 may cover a portion of the outer circumferential surface of the inspection pipe P so as to correspond to the diameter of the inspection pipe P. As a result, since the fusion sensor module 10 according to the embodiment of the present invention can be applied to the inspection pipe P having various diameters, there is an advantage of having versatility. The connection member 220 may be formed of a material having good corrosion resistance, and may be formed of SUS304 material among materials having good corrosion resistance.

Meanwhile, the housing 140 accommodating the fusion sensor 100 is formed on the mounting part 200. At this time, the plurality of plates 210 of the mounting portion 200 is composed of a central plate 212 formed to be parallel to the ground, and a side plate 214 formed to form an acute angle with the ground, the fusion sensor 100 When the housing 140 accommodated is formed on the side plate 214 formed at an acute angle with the ground, it is installed in the test pipe P in an unstable state, so that the fusion sensor 100 may be separated from the test pipe P. There is this. Accordingly, the housing 140 accommodating the fusion sensor 100 may be formed on the center plate 212. Since the housing 140 accommodating the fusion sensor 100 is formed on the central plate 212, there is an advantage that can be stably installed on the inspection pipe (P).

In addition, the housing 140 accommodating the fusion sensor 100 includes at least one magnetic material (not shown). The magnetic material may be formed on the lower surface of the housing 140. Preferably, the magnetic material may be used to fix the micro-vibration sensor 130 of the fusion sensor 100 to the housing 140, the housing 140 containing the fusion sensor 100 is mounted on the mounting portion 200 Two or more may be used to stably install on the. That is, the inside of the housing 140 containing the fusion sensor 100 may preferably include at least three magnetic materials.

On the other hand, the mounting portion 200 may include at least one magnetic body 230 on the surface in contact with the plurality of plates 210 and the inspection pipe (P). At this time, the magnetic body 230 may be formed only on the surface where the center plate 212 and the test pipe (P) contact, the part or all of the center plate 212 and the side plate 214 and the test pipe (P) contact It can be formed on the side. By forming the magnetic body 230 between the plate 210 and the test pipe (P), the mounting portion 200 has an advantage that can be stably coupled to the test pipe (P) formed of a paramagnetic material without mechanical fastening. In addition, the magnetic body formed inside the housing 140 that accommodates the fusion sensor 100 has a magnetic attraction with the magnetic body 20 formed on the surface in contact with the central plate 212 and the inspection pipe (P) fusion sensor 100 The housing 140 accommodated therein may be stably installed on the central plate 212, and as a result, the fusion sensor 100 may be stably positioned in the inspection pipe P to enable precise sensing.

5 is a signal transmission flowchart of the fusion sensor system according to an embodiment of the present invention, Figure 6 is a top view of the data collecting unit 30 according to an embodiment of the present invention.

Referring to FIG. 5, in the fusion sensor system according to an exemplary embodiment of the present invention, information measured by the fusion sensor 100 is collected in the data collecting unit 30, and the data collecting unit 30 collects the collected information. The transmission may be transmitted to the display unit 40 through the wireless router 330. Referring to FIG. 6, the data collection unit 30 may include a battery 310, a charging module 340, and a power module 320. The day collector may receive external power by wire through the power module 320 for stable power supply. However, the battery 310 corresponding to the auxiliary power may supply the power of the data collection unit 30 to perform data collection even in a situation where power supply is difficult by wire due to a site situation such as a power failure. Therefore, there is an advantage that the power module 320 or the battery 310 can stably supply power to the data collection unit 30 to collect the values sensed by the fusion sensor 100. On the other hand, the data collection unit 30, including the charging module 340 when the battery 310 is supplied with power in a wired state without a buffer state, supplying power to the battery 310 through the charging module 340 And by charging it can be supplied to the power of the data collector 30 again through the battery 310 in a situation where it is difficult to supply power by wire.

Meanwhile, when the measured values sensed by the fusion sensor 100 are received in the data collecting unit 30 and the values are transmitted to the display unit 40, wired communication may be used. However, if it is difficult to use wired communication in accordance with the site situation, by including a router 330 for enabling wireless communication, even if the wired communication with the display unit 40 and the fusion sensor 100 is not connected to each other There is an advantage that can transmit and receive measured values. In addition, the router 330 may be a Long Term Evolution (LTE) router, but may use any mobile communication standard that enables wireless communication.

The display unit 40 displays the measured value sensed by the fusion sensor and may output a caution message when there is a measured value out of the normal range. On the other hand, if the measured value out of the normal range is 2 or more or if the measured value is significantly out of the normal range, a warning message or an alarm sound can be generated through a separately connected speaker to prevent abnormality of the quick inspection pipe (P). It is possible to prevent human injury and property loss early.

7 is a flowchart illustrating a control method of a fusion sensor system according to an exemplary embodiment of the present invention.

7, the control method of the fusion sensor system according to an embodiment of the present invention, each sensor in the fusion sensor 100 senses the measured value of the inspection pipe (P) (S10). In this case, the fusion sensor 100 may include an acceleration sensor 110, a vibration sensor 120, a micro vibration sensor 130 as described above, and may further include additional sensors such as a temperature sensor. Sensors constituting the fusion sensor 100 senses the measured value for the inspection pipe (P) and transmits the sensed measured value to the data collection unit (30).

The data collector 30 determines whether to output a warning message based on the measured value sensed by the fusion sensor 100 (S20). This is defined as a first determination step.

Sensor 1 Sensor2 Sensor 3 Sensor 4 Sensor 5 result weight 0.2 0.2 0.2 0.2 0.2 One Example 1-1 X X X X X No response Example 1-2 O X X X X Warning message output Example 1-3 O X O X X Alarm

Referring to Table 1, it is assumed that five sensors are integrated to form one fusion sensor, and all sensors have the same weight. On the other hand, such a weight may have a higher value (weighted value) of the sensor sensing an important factor that can determine whether the impact or deformation of the test pipe (P). In addition, when the measured value of the sensor is out of the normal range it was distinguished by displaying "O", and if it corresponds to the normal range. When the fusion sensor monitors the condition of the inspection pipe (P), if the measured values of all the sensors are within the normal range as shown in Example 1-1, it is determined that no impact or deformation occurs in the inspection pipe (P). It is not necessary. Therefore, the fusion sensor 100 continuously senses the state of the inspection pipe (P).

In the case of Example 1-2, since the measured value of one or more sensors of each sensor is out of the normal range, the data collection unit 30 determines that an abnormality has occurred in the inspection pipe P and signals the display unit 40. By transmitting the display unit 40 to output a warning message (S30). By outputting a warning message, the user can determine that the inspection pipe P is shocked or deformed and take necessary measures. Similarly, in the case of Examples 1-3, since the measured values of the sensor 1 and the sensor 2 are out of the normal range, the display unit 40 may output a warning message.

Meanwhile, the data collector 30 determines whether to generate an alarm based on the measured value sensed by the fusion sensor (S40), and defines this as a second determination step. Therefore, when the sum of the weights of the sensors outside the normal range of the measured value of each sensor according to the second determination step is greater than or equal to the preset weight, the data collection unit 30 transmits a signal to the alarm unit so that the alarm unit generates an alarm (S50). can do. In this case, the preset weight may be 0.4, but is not necessarily limited to this value, and may be changed according to the sensor and the environment used by the user. In the case of Example 1-3, since the sum of the weights of the sensors outside the normal range is 0.4, the state of the inspection pipe P is determined to be dangerous, and the data collection unit 30 may transmit a signal to the alarm unit to generate an alarm such as a siren. have. As a result, the user can quickly repair the inspection pipe (P) or quickly leave the area, thereby minimizing human and property damage.

Sensor 1 Sensor2 Sensor 3 Sensor 4 Sensor 5 result weight 0.4 0.3 0.1 0.1 0.1 One Example 2-1 X X X X X No response Example 2-2 X X O X X Warning message output Example 2-3 X X O O X Warning message output Example 2-4 X O X X X Warning message output Example 2-5 X O X O O Alarm Example 2-6 O X X X X Alarm

Referring to Table 2, it is assumed that five sensors are integrated to form one fusion sensor, and that sensor 1 and sensor 2 have a higher weight than sensors 3 to 5. In addition, when the measured value of the sensor is out of the normal range it was distinguished by displaying "O", and if it corresponds to the normal range. When the fusion sensor 100 monitors the state of the inspection pipe P, it is determined that the shock pipe or the deformation does not occur in the inspection pipe P when the measured values of all the sensors are in the normal range as shown in Example 2-1. No further action is required. Therefore, the fusion sensor 100 continuously senses the state of the inspection pipe (P).

In the case of Example 2-2, since the measured value of the sensor 3 among the sensors is out of the normal range, the data collection unit 30 determines that an abnormality has occurred in the inspection pipe P and sends a signal to the display unit 40. By transmitting the display unit 40 to output a warning message (S30). By outputting a warning message, the user can determine that the inspection pipe P is shocked or deformed and take necessary measures. Similarly, in the case of Examples 2-3 and 2-4, since the one or more measured values are out of the normal range, the display unit 40 may output a warning message.

Meanwhile, the data collector 30 determines whether to generate an alarm based on the measured value sensed by the fusion sensor (S40), and defines this as a second determination step. Therefore, when the sum of the weights of the sensors outside the normal range of the measured value of each sensor according to the second determination step is greater than or equal to the preset weight, the data collection unit 30 transmits a signal to the alarm unit so that the alarm unit generates an alarm (S50). can do. In this case, the preset weight may be 0.4, but is not necessarily limited to this value, and may be changed according to a sensor and an environment used by the user. In the case of Example 2-5, since the sum of weights of the sensors outside the normal range is 0.5, the state of the inspection pipe P is determined to be dangerous, and thus the data collection unit 30 may transmit a signal to the alarm unit to generate an alarm such as a siren. have. As a result, the user can quickly repair the inspection pipe (P) or quickly leave the area, thereby minimizing human and property damage.

In the case of Example 2-6, only one sensor (Sensor 1) constituting the fusion sensor 100 is out of the normal range, but since the weight of the sensor 1 is 0.4, the data collection unit 30 is an alarm unit in this case. A signal can be sent to generate an alarm such as a siren. As a result, the user can quickly repair the inspection pipe (P) or quickly leave the area, thereby minimizing human and property damage.
