In the illustration, the canal water level and water quality monitoring device 32 is set in the irrigation ditch 11, The soil of the farmland 50 is provided with a soil quality and water level monitoring device 34. Before irrigation, the central control system 40 obtains the canal water level information, canal water quality information, soil quality and water level information from these monitoring devices, analyzes and compares this information, and if the canal water level and water quality meet The standard indicates that the canal water can be supplied for irrigation. The central control system 40 sends a command to the release pipe control mechanism 18 to release the cable 181, and releases the discharge pipe 15 to the release position for release. The discharge through the flow meter 31 is also transmitted to the central control system 40. The central control system 40 calculates the discharge. When the discharge reaches a predetermined value or the level of the canal water is not sufficient to provide irrigation, the central control system 40 sends a command to The discharge pipe control mechanism 18 pulls the discharge pipe 15 back to the cutoff position, and stops the drainage of the canal water to the farmland 50. The field monitoring device 36 can be used to capture water level images of the irrigation ditch 11 and the farmland 50, as well as operation images of the channel water irrigation equipment 10.

As shown in Figs. 6 to 8, the field water discharge device 20 includes: a release box 21, a water inlet 22 provided at one end of the release box 21, a discharge port 23 provided at the other end of the release box 21, and a release box A guide plate 24 which can be tilted up and down in 21 and a guide plate control mechanism 25 provided on the upper part of the guide box 21. The lead plate control mechanism 25 includes a motor shaft 252 that retracts and releases the moving wire 251 and a tension wheel 253 that maintains the tension of the actuation wire 251. The actuating wire 251 is connected to the tilting end 241 of the lead plate 24. The retracting and actuating of the actuating line 251 controls the guide plate 24 in a guide position (as shown in FIG. 7) or a stop position (as shown in FIG. 8). The release position is that the height of the tilting end 241 of the discharge plate 24 is lower than the lowest point of the water inlet 22; the stop position is the height of the tilting end 241 of the discharge plate 24 is higher than the lowest point of the water inlet 22 and higher than Water level of farmland 50.

In the illustration, a soil quality and water level monitoring device 34 is set in the farmland 50 to monitor the soil quality and water level of the farmland 50. The central control system 40 obtains the water level height information of the farmland, analyzes and compares this information, and when the water level of the farmland 50 exceeds the standard value (e.g. Water to the farmland 50), the central control system 40 sends a command to the release board control mechanism 25 to release the actuation line 251, lower the release board 24 to the release position, and the water in the farmland 50 passes through the water inlet 22 of the release box 21 , The discharge plate 24 is excluded from the discharge port 23; the soil quality and water level monitoring device 34 and the central control system 40 continuously monitor the farmland 50 water level height. When the farmland 50 water level height meets the standard value, the central control system 40 sends an order to The lead-in board control mechanism 25 rolls up the actuation line 251 and pulls the lead-in board 24 to the stop position to stop the farmland water from being led outward. In addition to the farmland water level exceeding standard discharge, the farmland water discharge and release device 20 can also be used to divert or stop water from a high farmland to a low farmland (as shown in FIG. 12), which will be described later. The field monitoring device 36 can be used to capture farmland water level images and operation images of field water discharge equipment.

As shown in Figures 9 and 10, in order to prevent water from seeping out from the gap between the two sides of the guide plate 24 and the side wall of the guide box 21 when the guide plate 24 is in the stop position, the present invention is applied to the guide box 21 A water introduction bag 26 is disposed on the inner and the discharge plate 24.

One end of the water introduction bag 26 is connected to the water introduction port 22 of the introduction box 21, the upper end of the fan-folded portion 261 is fixed to the introduction box 21, and the introduction plate 24 supports the water guide 262. When the lead-in board 24 is located at the lead-in position, the fan-folded portion 261 automatically hangs and unfolds, and the farmland water enters the lead-in bag 26 through the lead-in port 22 and is discharged from the drain port. When the guide plate 24 is located at the stop position, the guide plate 24 lifts the water guide portion 262 upward, and the fan-folded portion 261 returns to a fan-folded shape.
