[0026] Please refer to Figure 1 and Figure 2, in the intelligent integrated biogas slurry irrigation system based on the Internet of Things in the embodiments of the present utility model, it includes a filtering device, a biogas slurry tank 410, an irrigation device and an Internet of Things control device 300. The filtering device includes a front-end filtering tank group and several tertiary filters 200. The front-end filtering tank group includes a receiving tank 110, a sedimentation tank 120 and a primary filtering tank 130 that are connected in sequence. The receiving tank 110 is used to receive the biogas slurry to be treated. The receiving tank 110 is connected to a storage tank 140. The storage tank 140 is used to store the biogas slurry to be treated. The primary filtering tank 130 is connected to several tertiary filters 200. A backwashing device 210 and a pressure sensor 220 are arranged in the tertiary filter 200. The backwashing device 210 is used to wash the filter screen. The pressure sensor 220 is used to monitor the clogging situation in the tertiary filter 200.

Both the biogas slurry pump 410 and the clear - water pump 510 are connected to the Internet of Things control device 300. A biogas slurry pipe 420 is connected between the biogas slurry pump 410 and the mixing device 600. A clear - water pipe 520 is connected between the clear - water pump 510 and the mixing device 600. The friction loss coefficients of the biogas slurry pipe 420 and the clear - water pipe 520 are equal. The mixing device 600 is also connected to an oxygen feeder 700 and the water - injector. The mixing device 600 is used for mixing biogas slurry, clear water and oxygen. Preferably, the mixing device 600 mixes the filtered biogas slurry and clear water in a certain proportion.

The biogas slurry pipe 420 and the clear - water pipe 520 have the same specifications. And because the friction loss coefficients are the same, the resistance of the fluid in the pipes is also the same. When the flow velocities of the liquid in the biogas slurry pipe 420 and the clear - water pipe 520 are the same, the running time of the biogas slurry pump 410 and the clear - water pump 510 can represent the water - fertilizer ratio. The Internet of Things control device 300 controls the water - fertilizer ratio by controlling the running time of the biogas slurry pump 410 and the clear - water pump 510. It can be understood that the Internet - of - Things - based integrated intelligent irrigation system for biogas slurry can intelligently regulate the water - fertilizer ratio, and through an appropriate water - fertilizer ratio, the effect of promoting crop growth and increasing yield can reach the best.

[0028] The water applicator is used for irrigating farmland 900. A number of pipeline monitoring devices and a number of irrigation valves are arranged inside the water applicator.

Specifically, the water applicator includes a number of irrigation pipelines 610. The irrigation valve and the pipeline monitoring device are both located on the irrigation pipeline 610. The irrigation pipeline 610 is placed on the surface of the farmland 900. A soil humidity sensor 310 is arranged inside the farmland 900, and an environmental monitoring device 320 is arranged outside the farmland 900.

The integrated intelligent biogas slurry irrigation system based on the Internet of Things has good reliability without a large amount of manual monitoring.

[0029] Preferably, the soil humidity sensor 310 uses a soil humidity sensor of model YL-69, which is inserted into the soil to continuously measure the humidity of the soil of the farmland 900. The environmental detection device 320 includes a temperature and humidity sensor, and the model of the temperature and humidity sensor is DHT11, which can measure the temperature and humidity in the atmosphere. It can be understood that in a high-temperature and relatively dry environment, the water demand of crops will increase. When it is monitored that the humidity is low, the Internet of Things control device 300 can control the water applicator to increase the irrigation frequency and proportion. In the case of high soil humidity, the water demand of crops is small. The Internet of Things control device 300 adjusts the water-fertilizer ratio according to the humidity of the current environment, reducing the proportion of water in it to ensure that crops obtain sufficient nutrition without wasting water, and preventing problems such as root hypoxia caused by overly wet soil.

The sensor module is used to collect data. The control module is connected to several backwashing devices 210, the biogas slurry pump 410, the clean water pump 510, and several irrigation valves. A water-fertilizer ratio calculation unit is provided in the parameter module, and the water-fertilizer ratio calculation unit is used to calculate the water-fertilizer ratio according to the humidity data. Preferably, the Internet of Things control device 300 is based on an esp series single-chip microcomputer. Specifically, the esp32 single-chip microcomputer is used. The Internet of Things control device 300 further includes a power supply module, where the power supply module can supply 5V and 3.3V voltages. The control module uses a pcf8574 IO expansion module and then connects a relay / Darlington array to control the working circuits of each component. The setting of the system control parameters in the parameter module includes the water-fertilizer ratio, irrigation time, irrigation interval time, filter pressure threshold, irrigation emitter pressure threshold, etc. Among them, the initial water-fertilizer ratio is 1:5 and is stored in the initial unit. The updated water-fertilizer ratio is stored in the storage unit after being calculated according to the humidity data. All parameters are continuously updated and optimized in the program deployed by the single-chip microcomputer according to the monitoring data. The storage unit uses a persistent memory EEPROM. When the user changes the parameter settings, they are written into the EEPROM and are not lost when the power is off. It can be understood that when the storage unit is damaged, the system can still perform basic intelligent control according to the parameters in the initial unit to ensure the normal operation of the system.

[0031] The communication module is connected to the parameter module and the intelligent terminal 800. The intelligent terminal 800 is used to process, display, and transmit data. The intelligent terminal 800 is connected to the cloud server 810. A data storage module is set in the cloud server 810, and the data storage module is used to collect and store the data uploaded by the intelligent terminal 800. Preferably, the protocol in the communication module adopts MQTT (Message Queuing Telemetry Transport) to complete the two-way transmission of data and control commands. A WIFI unit is set in the communication module. The WIFI unit searches for and connects to the wireless network with the strongest signal nearby according to the data credentials set in the parameter module, so as to connect to the Internet, which is convenient for starting monitoring and database connection. The intelligent terminal uses a computer, and the computer is equipped with an OLED display driven by ssd1306. The network connection status and sensor readings are displayed in the form of relevant processed charts through the I2C protocol. An interactive interface is also displayed on the display screen for the user to control the integrated intelligent biogas slurry irrigation system based on the Internet of Things.

[0032] Furthermore, the Internet of Things control device 300 has two modes, namely the intelligent takeover mode and the manual control mode. In the manual control mode, the user controls the running time of each water pump and the operation of each relay on the intelligent terminal 800. In the intelligent takeover mode, the operation of each link is monitored and controlled according to the parameter settings in the Internet of Things control device 300, and the Internet of Things control device 300 can regularly upload monitoring data to the cloud server 810 for data collection and visualization in the cloud.
