Water and fertilizer integrated sprinkler irrigation control system

Abstract

The invention discloses a water, fertilizer and pesticide integration sprinkler control system. The system comprises several wireless soil moisture sensors, a wireless transmission network, an upper computer used for decision making and a lower computer used for controlling an electrical-control execution mechanism; the upper computer is connected with a wireless serial transmission station through a serial port, the wireless serial transmission station is connected with the lower computer through wireless signals, and the lower computer is connected with the electrical-control execution mechanism; the upper computer is connected with a wireless network transmission station through a network cable, the wireless network transmission station is connected with the wireless soil moisture sensors through wireless signals, and the lower computer is connected with a power source; the electric quantity of the power source is displayed and monitored on a computer through the wireless serial port, the wireless soil moisture sensors are distributed in soil mesh division units, and are responsible for collecting the soil moisture situations of fertilization land parcels and transmitting data into the upper computer in real time, and a liquid level collector and a camera are fixed on a rack of a water spraying vehicle, and connected with a controller through wireless transmission.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a control system for a sprinkler irrigation machine integrating water, fertilizer and medicine. Background technique [0002] The reel sprinkler irrigation machines in the prior art generally can only use leaf surface flushing fertilization, and the existing defects are that the degree of automation is low, the workload of manpower control operation is heavy, and the working conditions of the sprinkler irrigation machine cannot be monitored in real time. Shutdown, the concentration of fertilizer is affected by the flow and pressure changes of the main pipeline, the pressure loss of the pipeline is large and difficult to control, the recovery speed of the water sprayer is not constant, which leads to uneven spray irrigation, and the lack of remote monitoring technology cannot realize unattended operation, etc., which cannot meet the requirements. The d...
