Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of monitoring devices, in particular to a real-time online monitoring device based on smart agriculture. BACKGROUND

[0002] The smart agriculture farmland monitoring device is a system device that uses modern information technology to monitor and collect data on agricultural production environment in real time. The system integrates Internet of Things, big data, cloud computing and artificial intelligence and other technologies to achieve comprehensive and accurate monitoring of farmland environment and crop growth status.

[0003] At present, the data collection of the system device includes soil monitoring by soil monitoring sensors and other data collection. However, the traditional installation support mode is a fixed buried structure. The sensor under such support structure is prone to probe corrosion, salt crystallization or root entanglement after long-term contact with soil, which in turn leads to a decrease in sensor sensitivity. Some existing devices attempt to realize the insertion and extraction of the sensor through a simple support lifting assembly, but due to the insufficient radial constraint and attitude holding function of the positioning mechanism, the support structure will tilt or jam the sensor during the insertion and extraction process, resulting in a positional deviation of the soil parameter collection point. In addition, the existing support transmission assembly adopts a continuous driving mode, which requires continuous power output to maintain the reciprocating support movement of the sensor, resulting in a significant increase in energy consumption. At the same time, there is a lack of intermittent timing coordination control between the support insertion and extraction action and the attitude positioning adjustment, which is prone to mechanism motion interference.

[0045] When ascending: the long plate 7 of the transmission mechanism contacts the lower surface of the ascending drive plate 20, pushes the reciprocating plate 17 upwards, the reciprocating long groove 18 slides along the fixed rod 13, synchronously drives the soil monitoring sensor 11 and the cable shell 19 to ascend, the cable shell 19 passes through the slot 14 of the fixed rod 13, and guides the orderly movement of the cable 10 when the reciprocating plate 17 ascends and descends;

[0046] When descending: after ascending to the preset height (when the rotating clamp 25 contacts the reciprocating plate 17), the long plate 7 is separated from the ascending drive plate 20, the short plate 8 rotates and drives the rotating clamp 25 to contact the reciprocating plate 17, so that the reciprocating plate 17 descends under the action of gravity until the descending clamp seat 22 is clamped with the clamping block 16 of the fixed plate 12, the descending action is limited, the soil monitoring sensor 11 is prevented from being quickly impacted on the soil, and the soil monitoring sensor 11 is ensured to be inserted into the soil to monitor.
