Example 1

The farm is divided into different areas for management according to the type of crops, and each area is further divided according to the size of the farmland. Considering cost savings and maximizing equipment utilization, the design of farmland division and equipment layout is shown in Figure 2. Three air and soil humidity and temperature sensors are arranged in each farmland, and three intelligent solenoid valve controllers are arranged together. When the data detected by the two adjacent sensors is lower than the set value, the two sensors will be automatically turned on. Solenoid valve corresponding to the irrigation point. The comparison table of sensor and solenoid valve control is shown in Table 1. When the C1-C12 sensor detects that the measured value is lower than the set value, the corresponding representation is 1, and the solenoid valve with the corresponding number in the same row will be opened. The design of Table 1 is conducive to the collection and management of information of sensors and solenoid valves, and can achieve precise management. The specific table is as follows:

Table 1 Sensor and solenoid valve control comparison table

The system uses the stc12 single-chip microcomputer as the sub-node control chip to collect the temperature and humidity information of the air and soil and the switch status of the solenoid valve. Through the HC-02 module of HC company, the collected information is transmitted to the regional management area and management personnel of the host collaborative platform. The host collaborative platform adopts STM32F4 series single-chip microcomputer, and the administrator decides whether to open the solenoid valve to control the water pump according to the parameters of the crops for irrigation. Then, the data is transmitted to the data center through the Intel network, and the refined management platform displays the data in real time, analyzes the current crop irrigation situation according to the big data, and feeds back the information to the administrator and the competent department in time.

After booting, enter the initialization program and start data collection. After the data is collected, the single-chip microcomputer compares the collected data with the set data and the weather conditions to determine whether to start irrigation. At the same time, irrigation can be controlled through the function keys and the host computer. If the water pump does not work when irrigation is required, the system will start to alarm. Finally, the data collected by the sub-nodes is sent to the big data analysis system and the remote control center.

The output of LP7-12 is 12V, and it adopts the step-down module of LX6009. This module uses the second-generation high-frequency switching technology XL6009E1 as the core chip, which has better performance and lower cost than LM2577. To meet the demand of 5V power supply for sub-nodes, the step-down circuit diagram is shown in Figure 4.

The solenoid valve is controlled by a 5V relay, and the circuit is shown in Figure 7. The single-chip microcomputer can compare the collected soil moisture with the set value to determine whether to irrigate or not. At the same time, it can also control whether the single-chip microcomputer port outputs a signal through the mobile phone APP, so as to control the relay on and off, and realize two modes of automatic irrigation and manual control.

The sub-node system is the most important part of this design. It is connected to other circuits externally, receives and processes data internally, and then outputs it. This design uses the 12-bit single-chip microcomputer of the STC series. Compared with other types of single-chip microcomputers, it has many types, fast execution speed, convenient operation through serial port programming, and self-contained AD conversion. The flow chart of the sub-node system is shown in Figure 8.

The air temperature and humidity of the sensor placement point and the soil humidity information are displayed on the top of each garden in a scrolling manner, and the open state of the solenoid valve is displayed in the control part. The control system part realizes the on-off of the relay through the button to achieve the irrigation effect of crops.

The platform is a web project developed based on the SSM framework. The lower computer is collected by the STM32F4 server through the serial port transparent transmission of the WiFi module ESP8266, and is controlled by AT commands. The data is transmitted to the PC through the Intel network, and the PC monitors the port data through the port monitoring program, and adds the collected data to the database.
