Description

TECHNICAL FIELD [0001] The present invention relates to a sensor module for detecting flooding and water level, and a control method thereof. BACKGROUND OF THE INVENTION 1. Field of the Invention [0002]

The present invention relates to a sensor module for immersion and level sensing and a control method thereof.

The area of land that can absorb rainwater in the case of rainfall has been reduced by road formation such as asphalt due to the recent urbanization. Although the urban drainage system prevents damage due to precipitation, when local rainfall occurs in a short period of time, the drainage system exceeds the limit of precipitation that can be treated, resulting in continuous human and material damage every year .

Conventionally, a sensor having components for generating ultrasonic waves has been used to confirm the flooding due to such heavy rainfall. Such a conventional sensor uses a method of generating an ultrasonic wave and then measuring the water level based on the time data when the generated ultrasonic wave returns to the sensor again.

1 is a perspective view of a sensor module 1 for immersion and water level sensing according to an embodiment of the present invention.

The sensor module 1 for detecting flooding and level of water according to an embodiment of the present invention includes a module cover part 300 formed on an inflow path where one side is opened and a fluid flows into an internal space, (100) formed in the gravity direction to sense the pressure applied by the fluid, the pressure sensing unit (110) being formed around the pressure sensing unit (110) And a first flood sensing unit 200 including a plurality of electrodes formed on the same plane and electrically insulated from each other. The module cover unit 300 includes a frame 310 formed at an edge thereof, And a module cover member 320 of a mesh shape covering the frame 310.

Referring to FIG. 1, a sensor module 1 for immersion and level sensing may be formed on one side of a wall W. FIG. At this time, the wall W may be the inner wall of the building interior. By providing the sensor module 1 for immersion and water level detection according to the present invention on the inner wall of a room, it is possible to substantially detect the immersion in the room.

FIG. 2 is a front view of a sensor module 1 for sensing flood and water level according to an embodiment of the present invention, and FIG. 3 is an exploded perspective view of a sensor module 1 for detecting flood and water level according to an embodiment of the present invention .

Referring to FIGS. 2 and 3, the module cover portion 300 is formed perpendicular to the paper surface, and has an inlet passage through which one side is opened to allow fluid to flow. A water level sensing unit 100 formed in the gravity direction is formed inside the module cover unit 300 in order to sense the pressure applied by the fluid when the pressure sensing unit 110 is exposed to the air. When the fluid flows into the module, the fluid level sensing unit 100 receives a force applied to the pressure sensing unit 110 of the level sensing unit 100, and converts the force (pressure) according to the area into an electrical signal . Thus, the electrical signal is processed by a predetermined process to measure the current water level. The pressure sensing unit 110 of the water level sensing unit 100 measures the pressure applied by the fluid in the direction opposite to gravity and various level sensors such as a capacitive pressure sensor and a float switch may be used as the water level sensing unit 100 have.

The first immersion sensing unit 200 is formed around the pressure sensing unit 110 at a lower portion of the level sensing unit 100. The first immersion sensing unit 200 is formed of a plurality of electrodes 210, and the plurality of electrodes 210 are insulated from each other. The plurality of electrodes 210 have a mutual capacitance. When the fluid flows into one open side of the sensor module 1 for sensing flood and water level during rain, the electrodes 210 are formed around the pressure sensing unit 110 So that the fluid flows onto the plurality of electrodes 210. The plurality of electrodes 210 are electrically insulated from each other when they are exposed to the air, but a short circuit occurs between the electrodes due to inflow of a fluid having a resistance lower than air. As a result, mutual capacitance changes, and the first flooding detection unit 200 measures whether the flooding occurs due to the change of the mutual capacitance. By configuring the sensor module 1 for sensing flood and water level integrally formed so as to have the water level sensing part 100 and the first flood sensing part 200 together, It is possible to know the immersion status of the installed area, and to measure the level of the immersion level to some extent, it is possible to increase the reliability of the measurement.

The pressure sensing unit 110 of the water level sensing unit 100 and the plurality of electrodes 210 of the first flooding sensing unit 200 are disposed on the same plane. The fluid is introduced into the sensor module 1 for immersion and level detection by the pressure sensing unit 110 and the electrodes formed on the same plane so that it is determined whether the first immersion sensing unit is immersed by the electrode 210, The pressure sensing unit 110 of the sensing unit 100 can acquire the level information by the water pressure. The first flood sensing unit 200 and the water level sensing unit 100 may operate simultaneously and the first flood sensing unit 200 may be operated first to determine that the flood sensing unit 200 is flooded, May perform operations.

2 and 3, the plurality of electrodes of the first immersion sensing unit 200 are shown as having a pair of rectangular parallelepiped shapes, but the present invention is not limited thereto and may be formed in various shapes and various numbers.

The module cover portion 300 of the sensor module 1 for immersion and water level sensing may include a frame 310 formed at an edge and a module cover member 320 in a mesh shape covering the frame 310 . The module cover unit 300 protects the sensor from physical impacts that may be applied to the sensors (the water level sensing unit 100 and the first flooding sensing unit 200) from the outside. Meanwhile, the module cover part 300 can form the frame 310 at the corner. The frame 310 may be formed of a material having a small deformation by an external force while maintaining the skeleton. On the other hand, a mesh-shaped module cover member 320 is formed to cover the frame 310. The module cover member 320 minimizes the movement of the foreign matter together with the fluid flowing into the sensors (the level sensing unit 100 and the first immersion sensing unit 200). It is advantageous to prevent the occurrence of a sensing error of the water level sensing unit 100 and the first flooding sensing unit 200 by minimizing the movement of the foreign matter to the sensor. At this time, the mesh size of the module cover member 320 minimizes the influence of the foreign matter sensing unit 100 and the first immersion sensing unit 200 on sensing the fluid, while minimizing the inflow of foreign matter into the sensor. And can be configured within a range. The module cover member 320 may be formed on the inner side (in the direction close to the sensor) with respect to the frame 310 or on the outer side (in the direction in which the fluid flows) with respect to the frame 310.

The module cover member 320 of the module cover part 300 may be formed to cover the holes formed in the frame 310. The number and the shape of the holes formed in the frame 310 are not limited to the drawings, Can be formed within a range that does not interfere with the inflow of the fluid while having a durability exceeding a certain level of the cover part (300).

On the other hand, one surface of the sensor module 1 for immersion and water level sensing may be constituted by the contact portion W '. The contact portion W 'is a portion in contact with the inner wall W on which the sensor module 1 for immersion and level sensing is installed. Since the contact portion W 'abuts on the inner wall W to hold the immersion and water level sensing sensor module 1 fixed, it can be formed as an elastic member for application to a wall surface. In addition, an adhesive material may be applied to a surface that is in contact with the wall surface so as to be adhered to the wall surface. Alternatively, the sensor and module cover portion 300 may be fixed to the wall surface through the fixing portion 800, as shown in FIG. By constituting the contact portion W 'and the fixing portion 800 with the sensor module 1 for immersion and level detection, there is an advantage that the sensor module can be stably supported on the wall surface and the reliability of sensing can be enhanced.

The height of the first end electrode 410, the second end electrode 420, the third end electrode 430, and the fourth end electrode 430 are set so that a plurality of layers of the plurality of electrodes are formed at equal intervals from each other, By disposing the short electrode 440, the mutual capacitance change of each short electrode can be used to detect the level of water level and to detect the water level. The plurality of electrodes formed by the plurality of layers of the second flood sensing unit 400 are also used for sensing the level of the water level. Thus, whether or not flooding is detected by the second flood sensing unit 400, The level of the water level sensed by the pressure sensing unit 110 of the water level sensor 110 can be measured together, thereby enhancing the reliability of the water level measurement.

Meanwhile, the second immersion sensing unit 400 may include a plurality of layers, and each layer may include a plurality of electrodes formed in parallel with the ground in a horizontal direction.

Referring to FIG. 9, when the first flooding detection unit 200 detects the flooding, the first flooding detection unit 200 transmits the flooding data to the controller 500 electrically connected thereto.

In addition, the immersion state of the first end electrode 410, the second end electrode 420, the third end electrode 430, and the fourth end electrode 440 by the second immersion sensing unit 400 is The second flood sensing unit 400 transmits the flood control data to the controller 500 electrically connected thereto. The control unit 500 can transmit the received data to the central system such as a situation room of the local government through the transmission unit 600. The central system that received this data judged the risk of the area according to the immersion and level information, and issued a warning alarm using the local loudspeaker installed in the area, You can tell. Meanwhile, the control unit 500 may be a board using a LoRa (Long Range, low power wireless platform) technology, and the transmission unit 600 may also transmit data to the central system through LoRa technology.

Meanwhile, the control unit 500 is electrically connected to a plurality of alarm units 700, and the alarm unit 700 includes a light emitting type alarm and a noise generating type alarm. In this case, the light emitting type alarm may be a monochromatic illumination, or may be a multicolor illumination that can emit different colors depending on the level. Further, the light-emitting type alarm can be controlled to be lit up when the water level of the predetermined height is measured, or can be controlled to flash with a predetermined time interval.

Hereinafter, a method of controlling the sensor module 1 for sensing flood and water level according to an embodiment of the present invention will be described in detail.

10 and 11 are flowcharts of a control method of the sensor module 1 for detecting flooding and water level according to an embodiment of the present invention.

The control method of the sensor module 1 for detecting flood and water level according to an embodiment of the present invention includes the steps of determining whether the first flooded sensing part 200 is submerged or not, A step of sensing the water level in the water level sensing unit 100, a step of determining whether or not the water level is based on the information sensed by the first water level sensing unit 200 and the water level sensing unit 100, And generating a signal.

Referring to FIG. 10, in the first immersion sensing unit 200, the immersion state is sensed according to a mutual capacitance change of a plurality of electrodes (S10). It is possible to sense whether the fluid is inundated by flowing the fluid and changing the mutual capacitance of the plurality of electrodes. Meanwhile, the water level sensing unit 100 may sense the water level (flooded water level) according to the pressure of the fluid in the pressure sensing unit 110 of the water level sensing unit 100 (S20a). The immersion sensing of the plurality of electrodes of the first immersion sensing unit 200 and the level sensing of the pressure sensing unit 110 of the level sensing unit 100 can be performed at the same time. Alternatively, the level sensing of the pressure sensing unit 110 of the level sensing unit 100 may be performed after sensing the immersion of the plurality of electrodes of the first immersion sensing unit 200. The sensed data is transmitted to the electrically connected control unit 500.

On the other hand, the control unit 500 determines whether the measured level is higher than a preset danger level based on the level data sensed by the pressure sensing unit 110 of the received level sensing unit 100 (S30). The predetermined hazard level can be set differently to match the zone height of the area. If the measured level is higher than the preset danger level, the control unit 500 controls the plurality of alarm units 700 to generate a danger signal (S40). At this time, the plurality of alarm units 700 may be a light emitting type alarm or a noise generating type alarm. By this process, the sensor module 1 for immersion and water level detection automatically performs the process from measurement to alarm generation, and it is advantageous to promptly inform the person in the room of danger by performing such a process. On the other hand, in the case of a person who is not free to move in the room, as described above, the control unit 500 transmits the data transmitted through the transmission unit 600 to the central system, can do.

In addition, the control method of the sensor module 1 for detecting the flooding and water level includes sensing whether the flooded water is in the second flooded sensing part 400, comparing information sensed by the second flooded sensing part 400, And a step of generating an abnormal signal when the information sensed by the second immersion sensing unit 400 is out of the error range of the information sensed by the level sensing unit 100 .

As described above, the second immersion sensing unit 400 may include a plurality of electrodes, and each layer may include a plurality of electrodes formed in parallel with the ground in a horizontal direction. The plurality of electrodes may be formed of a first electrode 410, a second electrode 420, a third electrode 430, and a fourth electrode 440 for each layer, but is not limited thereto The number of layers (stages) can be changed if necessary. If the plurality of electrodes of the second flood sensing part 400 of each layer are sensed whether or not the flooding is performed, it can be expected that a water level is formed between the layer sensed to be immersed and the layer not sensed to be immersed. The immersion sensing data of the second immersion sensor 400 is transmitted to the controller 500 electrically connected thereto.

On the other hand, the control unit 500 controls the second flood sensing unit 400 based on the immersion data sensed by the second flood sensing unit 400 and the level data of the level sensed by the pressure sensing unit 110 of the water level sensing unit 100, (S50) whether the sensing data of the sensing unit 400 is within the error range of the sensing data of the level sensing unit 100. At this time, if it is determined that the immersion sensing data of the second immersion sensor 400 is out of the error range of the sensing data of the level sensor 100, the sensor of the immersion & It is determined that a problem has occurred, and the control unit 500 can control the plurality of alarm units 700 to generate an abnormal signal (S60). The plurality of alarm units 700 may include a light emitting type alarm and a noise generating type alarm. On the other hand, the abnormal signal display of the plurality of alarm units 700 may be different from the danger signal display described above. For example, in a light emitting type alarm, a red lamp may be turned on as a danger signal, and a yellow lamp may be turned on as an abnormal signal. Or as a danger signal, the lamp of a specific color can be controlled to be turned on and the lamp of a specific color to blink as an abnormal signal. In addition, it is possible to control the noise generating type alarm to generate different noises from the danger signal and the abnormal signal. On the other hand, the control unit 500 can send an abnormal signal to the central system through the transmission unit 600, so that the abnormality of the sensor module 1 can be promptly detected and processed.
