Embodiment Construction
[0029] A water and fertilizer integrated machine based on multi-channel flow control and its flow control method of the present invention will be described with reference to the accompanying drawings.
[0030] Such as figure 1 A water and fertilizer integrated machine based on multi-channel flow control according to the present invention includes: a PLC control system 1 , an execution system 2 and a data acquisition system 3 . The PLC control system 1 runs a control algorithm to control the execution system 2 according to the data collected by the data collection system 3 .
[0031] The data acquisition system 3 includes: a plurality of flowmeters 31 for collecting the real-time flow of the main pipeline and the branch pipeline in the water and fertilizer pipeline; a remote pressure gauge 32 for collecting the pressure at the water outlet of the water pump, and the pressure at the water outlet is converted into an analog voltage signal Pass to PLC control system; EC value sen...
