For example, the sensor module 212 may include a sensor that detects an object in a non-contact manner, such as an ultrasonic sensor or an optical sensor. The sediment detecting unit 210 according to an embodiment of the present invention may include a plurality of the sensor modules 212 to detect sediment according to a preset sensing unit. The management server 400 receiving the detection information from the sediment detection unit 210 may detect a sediment height by selecting an appropriate measurement value from the sediment detection information.

In addition, the sensor module 212 may detect a flow rate or a water level. To this end, the sensor module 212 may include a sensor capable of sensing moisture and / or a sensor capable of measuring the conductivity of sediments. For example, the sensor module 212 can measure the conductivity between the sediment 500 and water, and the ultrasonic sensor that detects the sediment 500 so that the water and sediment 500 can be detected separately. And a conductivity measurement sensor. As such, the sensor module 212 may include a complex sensor to distinguish and detect water and sediment 500.

You can. The wireless communication unit 214 may cover the distance range of about 100 ~ 150m to perform wireless communication.

When the sensor module 212 detects the sediment 500, the processor 216 may change the sediment detection unit 210 from a standby mode to an active mode. For example, when the sediment 500 is detected from the sensor module 212, the processor 216 changes the power mode of the power unit 218 to an active mode, and detects the detection information through the wireless communication unit 214. It may be transmitted to other sediment detection units 210 around.

In addition, the processor 216 may increase the period of use of the power supply unit 218 by adjusting the sensing interval (eg, about 5 seconds) of the sensor module 212. The processor 216 may increase the use period of the power supply unit 218 as the sensing interval of the sensor module 212 is increased, so that the detection period of the sediment 500 and the use time period of the power supply unit 218 are appropriate. The sensing interval can be set in consideration.

In addition, the processor 216 may adjust the sensing interval of the sensor module 212 using weather information received from the management server 400.

In addition, the active mode may be a mode in which the wireless communication unit 214 is activated and transmits a signal to the surrounding sediment detection unit 210 as a high power mode. The power unit 218 may include a power storage device. For example, the power supply unit 218 may include a power storage device composed of a battery that can be used for about 6 to 8 months, a solar cell using solar heat, a battery using a piezoelectric element, and a battery using a magnetic field. . At this time, the power supply unit 218 may further increase the use time by adding a battery of the power storage device, and may control the use time by managing the capacity and / or number of the batteries.

In addition, the sediment monitoring system according to an embodiment of the present invention may implement a wireless mesh network (WMN) in an ad-hoc (AD-Hoc routing) manner. For example, when the sediment detecting unit 210-1 detects the sediment and switches from the standby mode to the active mode, detection information such as activation time and node information may be transmitted to the adjacent sediment detecting unit 210-2. Through this, in the sediment monitoring system according to an embodiment of the present invention, the sediment detection unit 210 does not communicate the signal one-to-one with the management server 400, but collects a signal through the gateway 300.
