[0056] Figure 4 A flow chart of a method for controlling open channel irrigation based on big data according to a preferred embodiment of the present invention is schematically shown. The method uses figure 1 , figure 2 and image 3 The shown open channel irrigation control system based on big data according to the preferred embodiment of the present invention.

[0057] Such as Figure 4 As shown, the open channel irrigation control method based on big data according to a preferred embodiment of the present invention includes:

[0058] The first step S1: using a liquid level sensor to measure the liquid level of the plot to be irrigated;

[0059] The second step S2: the liquid level of the land to be irrigated measured by the liquid level sensor is assigned a unique identification code with the equipment composed of the liquid level sensor and the valve device, and transmitted to the cloud management system;

[0060] For example, the LoRa antenna can be used to transmit d
