Soil Movement Detection Capsule Sensor

basic information

Here are the functions and features of the capsule sensor: 1. The wireless module moves with the movement of soil and debris, sending wireless alerts. 2. The capsule sensor is compact, with a diameter of 10 cm, and does not require civil engineering for installation. 3. The wireless module is inexpensive, allowing for the construction of a cost-effective system. 4. Each wireless module has its own ID information, enabling the simultaneous installation of multiple sensors without interference. 5. The line of sight distance between the receiving device and the sensor is approximately 500 meters. Sensors installed more than 500 meters upstream can still be monitored, although they require waiting time. 6. The internal battery life of the sensor is over 5 years (reference value), allowing for long-term reliable system operation (reference). 7. A high-gain Yagi antenna is used as standard for the receiving device. 8. It is also possible to use two receiving devices, distributing antennas in upstream and downstream directions to monitor a line of sight distance of approximately 1 km (optional). 9. The receiving device operates on solar power, so commercial power supply is not required. 10. The receiving device has a built-in battery that can operate for 72 hours. 11. A system that reports detection information via email or similar means is also possible (optional).

Applications/Examples of results

It is effective in a wide area from the upstream of rivers to the estuary. 1. Locations where bank collapse is expected along steep streams, etc. 2. Locations where riverbeds and river shapes change significantly in fast-flowing rivers. 3. Locations where erosion, scouring, leakage, or overtopping is expected due to soil quality or structural issues of the embankment. 4. Locations where avalanches or the effects of spring snowmelt water are a concern in heavy snowfall areas. System components: 1. Capsule sensor (buried in sediment) ⇒ The built-in wireless device reports sediment movement. ⇒ The built-in battery has a lifespan of over 5 years (for reference). 2. Receiving device (installed on riverbanks, etc.) ⇒ It receives signals with high sensitivity using space diversity and broadly using simplex method. ⇒ It is equipped with a battery that operates for 72 hours. ⇒ It implements an optical transmission device. 3. Processing display device (installed in offices or branch offices) ⇒ Based on database information, it displays the occurrence of sediment movement, time, and location. ◇ For details, please refer to the specifications. ◇
