Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy monitoring, and particularly relates to a remote measurement terminal for automatic control of a gate. Background Art

[0002] In the process of current water conservancy informatization, the informatization management of irrigation areas is very important. The informatization management of irrigation areas is beneficial to optimizing the allocation of water resources, ensuring the balanced distribution of irrigation water, and scientifically analyzing the utilization of water resources.

[0003] Among them, the key point of the management of irrigation areas lies in the management of irrigation canal gates, and it is necessary to control the gates according to the required water flow rate. The control process requires timeliness, and in the context of informatization, multi-gate linkage management needs to be realized.

[0004] The traditional method for controlling the flow rate of irrigation canals is to adopt the way of manual measurement and manual opening and closing of gates. It is difficult to guarantee timeliness, the control accuracy is insufficient, the automation is insufficient, and the efficiency is low. In the face of the situation of multi-gate linkage, even if remote automatic control is introduced, there are still deficiencies in aspects such as accuracy and intelligence, and the access workload is large, and the implementation difficulty and maintenance difficulty are large. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a remote measurement terminal for automatic control of a gate, aiming to solve the problems of insufficient accuracy, intelligence, implementation difficulty and maintenance difficulty in the management of irrigation areas in the prior art.

[0006] In order to achieve the above purpose, the utility model is realized by the following technical solutions:

The gate system is controlled by the motor system, and the precise position of the gate is monitored by the monitoring component and fed back to the microcontroller in real time to complete the precise intelligent control of the gate; By setting the photovoltaic power supply system, there is no need for complex systematic wiring. The automatic control telemetry terminal of the gate is independently powered by the photovoltaic power supply system, which is easy to maintain and has strong durability. In the case of multi-gate linkage, the implementation difficulty of linkage is greatly reduced, and it can still operate in the scenario where mains power supply is unavailable, having adaptability and practicability; By setting the communication module, remote reporting and remote control can be completed.

The drive circuit 200 is connected to the flow sensor 100. The motor system includes a DC motor 420, a motor protector 430 and a motor forward and reverse controller 440. The DC motor 420 is connected to the motor forward and reverse controller 440. A motor protector 430 is arranged between the DC motor 420 and the motor forward and reverse controller 440. The motor forward and reverse controller 440 is connected to the microcontroller 300. The DC motor 420 is connected to the gate system. The gate system includes a gate 400 and a monitoring component. The gate 400 is connected to a screw rod 410. The screw rod 410 is connected to the DC motor 420. The DC motor 420 is used to drive the gate 400 to lift and lower.
