Detailed ways

As shown in Figure 1, the present invention relates to a real-time control system for the water level of a paddy field, which detects the height of the water level of the paddy field 100 through a liquid level sensor. The paddy field in Figure 1 is only a schematic diagram for easy understanding, and a real paddy field of any shape can actually be used. , compare the measured water level height value with the value set in the single-chip microcomputer, but the single-chip microcomputer sends a signal to the valve to control the inflow and outflow of water, so that the water level is always at a suitable height; specifically, including the monitoring terminal 1 , control terminal 2, radio frequency module 3 and power supply module 4, the monitoring terminal 1 is installed in the rice field, the related modules and circuits of the control terminal 2 are installed next to the rice field, the radio frequency module 3 is mainly a radio frequency chip, the model is LT8910, which is The data exchange between the water level monitoring terminal and the control terminal provides radio frequency signals, thereby realizing wireless communication.

As shown in FIG. 2 , the monitoring end 1 includes a water level sensor 11 , a first MCU module 12 and a fixing device 13 . The model of the water level sensor 11 is L-DP601, and the fixing device 13 includes a foam suspension board 131 . The waterproof box 132 is equipped with the radio frequency module 3 and the first MCU module 12. A thin rope is used to connect the foam suspension board, and the other end of the thin rope is connected to a steel nail and fixed in the rice field, so as to prevent the monitoring end from drifting. too far away. The water level sensor 11 is installed on the bottom of the paddy field, approximately in the center, and the position is determined by the manual calculation of the installation workers in the early stage, so that it is convenient to obtain more comprehensive water level data. It will automatically transmit the water level value directly to the first MCU module through the cable. After the first MCU module processes the data, it will send the data to the control terminal through the radio frequency module.

The control end 2 includes a water inlet valve 21, a water outlet valve 22, a second MCU module 23 and an LCD display screen 24. The water inlet valve 21 introduces the water in the reservoir according to the signal transmitted by the second MCU module. So as to carry out the water inflow operation of the paddy field, it is installed at the upstream reservoir, and the outlet valve 22 removes the water in the pool according to the signal sent by the single-chip microcomputer, and is installed at the downstream diversion ditch. The two MCU modules 23 are connected to display the height of the water level.

When the water level sensor 11 reads the value of the water level and feeds it back to the first MCU module 12, the first MCU module 11 transmits the processed data to the second MCU module 23 through the radio frequency module 3, and the second MCU module 23 receives the data Then, drive the water inlet valve 21 or the water outlet valve 22 to work.
