Cloud intelligent water and fertilizer machine is a combination of Internet of Things technology and automatic irrigation and fertilization technology. Zuoan Xinhui Electronic Technology Co., Ltd. has high-precision digital intelligent sensors, intelligent cloud terminals, and Zuoan intelligent cloud platform, which can provide IoT technology support for the cloud intelligent water and fertilizer integrated machine. In terms of automatic irrigation and fertilization technology, the left bank has adopted a diaphragm pump as an acti ve fertilizer suction pump. According to the water and fertilizer requirements of different crops, the soil environment and nutrient content conditions, it can automatically detect, allocate and supply water and fertilizer to achieve precise control. Irrigation amount, fertilization amount and irrigation and fertilization time.

   The intelligent digital fertilizer control and acid-base level inspection device is the core module of the Zuoanyun intelligent water and fertilizer integrated machine. It supports modbus standard protocol, supports 4-channel diaphragm pump fertilizer adjustment control, 1-channel acid-base control and upper and lower limit alarms. Fertilizer adjustment: According to the flow characteristic curve of the diaphragm pump and the detection value of the EC (conductivity) sensor, fast 2-point matching calculates the duty ratio of the diaphragm pump frequency conversion signal, and the flowmeter measurement value is used as the negative feedback signal of the diaphragm pump flow rate adjustment, strictly in accordance with 4 The proportion of road fertilizers adjusts the flow rate of 4-channel fertilizers, so that the EC value of the fertilizer can quickly match the preset EC concentration range. Adjust acid and alkali: According to the flow characteristic curve of the diaphragm pump and the detection value of the PH sensor, the duty ratio of the frequency conversion signal of the diaphragm pump is quickly tracked and matched, and the measured value of the flowmeter is used as the negative feedback signal of the diaphragm pump adjustment, so that the PH value of the fertilizer can quickly match the preset PH value range.
