Problems solved by technology
Real-time performance is very important for automatic irrigation control system. The real-time performance of sensor data acquisition also determines the timeliness of irrigation decision-making. At the same time, irrigation control instructions must also be transmitted to solenoid valves in real time to ensure precise control of irrigation water volume; network environment and System architecture is the main factor affecting real-time performance. Usually, under certain engineering conditions, the network transmission speed is determined. At this time, the system architecture plays a decisive role in real-time performance; the current irrigation control software system is mainly based on client / server The desktop application developed by (C / S) structure, the communication efficiency between the client software and the database is very high, and the network structure is simple, so the real-time performance of the system can be effectively guaranteed; however, because the C / S structure program must run on a specific The software and hardware platform cannot cover a variety of equipment platforms, and the scope of application is very limited, and it is not feasible to develop for all possible platforms in most cases; in addition, the C / S structure program upgrade and maintenance costs are high, and it is difficult to implement Centralized management of multiple projects
