This invention discloses a soil volumetric water content (VWC) measurement system based on LoRa-RSSI and a drone. The system comprises several underground LoRa nodes for collecting environmental monitoring data; a host computer embedded in the soil; and an aerial node carried by a small drone. Combining IoUT technology, this invention designs an innovative system for soil VWC measurement based on LoRa received signal strength and a drone. The system utilizes the changes in LoRa-RSSI between the soil's internal transmitter and the drone's aerial receiver during the drone's angular rotation. Combined with a Long Short-Term Memory (LSTM) network, it collects differential LoRa-RSSI values ​​and uses a deep learning (DL) algorithm to calculate soil VWC, achieving relatively accurate soil VWC data. This invention eliminates the need for depth measurement of VWC data, utilizes soft sensors to measure soil VWC, and offers low cost, high efficiency, and small measurement error, providing a novel approach for soil VWC measurement design.

This invention relates to the hardware structure of an endoscopic underwater inspection robot for irrigation canals, belonging to the field of irrigation canal inspection technology. It includes an inspection main body with a tracked walking mechanism at its lower end. A fluid channel runs through the main body from front to back, and a generator is fixedly mounted in the middle of the inner side of the fluid channel. The generator's input shaft faces the rear opening of the fluid channel and has an impeller fixedly mounted thereon. Three robotic arms are fixedly mounted outside the front opening of the fluid channel, and three inspection sub-bodies are slidably mounted inside the front opening of the fluid channel. A main body detection component is mounted on the top front side of the main body, and sub-body detection components are mounted at the front ends of the sub-bodies. This invention solves the problems of low detection efficiency, low drive efficiency, complex control, and insufficient endurance of current irrigation canal inspection equipment.

A liquid spray board eraser comprises a shell and a liquid spray bottle installed in the shell; the shell comprises an upper cover and a base connected with each other, one side of the upper cover or the base is provided with a notch, the upper cover and the base are provided with a quick release structure at the side provided with the notch, the quick release structure comprises an elastic buckle, one end of the elastic buckle is fixed in the base and the other end is a free end, the free end of the elastic buckle extends into the notch and a clamping through groove is arranged at the end; a clamping hook, one end of the clamping hook is fixed in the upper cover and the other end is provided with a hook part, the hook part can be connected into the clamping through groove of the elastic buckle; when the upper cover is covered on the base, the hook part of the clamping hook is clamped into the clamping through groove of the elastic buckle; when the elastic buckle in the notch is pressed, the hook part of the clamping hook is separated from the clamping through groove of the elastic buckle so that the upper cover and the base can be separated. The liquid spray board eraser is convenient to disassemble and is not easy to damage the product.
