Description

technical field [0001] The invention relates to the field of seawater desalination, and relates to a seawater desalination control system, in particular to a reverse osmosis seawater desalination control system. Background technique [0002] With the continuous development of the economy and the improvement of people's living standards, the demand for water is increasing, and the requirements for water quality are getting higher and higher. However, the shortage of water resources, the uneven distribution of time and space, and the excessive exploitation, Unrestrained waste and random pollution have exacerbated the tension between supply and demand of water resources. In drought years, the shortage of water resources not only seriously affects normal industrial and agricultural production, but also affects people's lives. With the development of the economy and the increase of the population, the water shortage will inevitably continue to increase. Seawater desalination, a...

Problems solved by technology

[0005] 1. The traditional reverse osmosis seawater desalination system adopts the field bus communication method, which has the disadvantages of complex structure, low transmission rate, difficult location of fault points and inconvenient debugging, etc.

[0006] 2. The upper computer is located in the central control room, generally some distance away from the site, and its main function is remote control. However, in the debugging stage or when the remote control terminal fails, basic operations such as on-site start and stop cannot be performed on site, which is not conducive to daily maintenance

[0007] 3. In order to realize the automatic control of the working process, the reverse osmosis seawater desalination system usually needs to use at least dozens of pneumatic switching valves. The traditional control system is to distribute air pipes and cables for each pneumatic switching valve in turn, and then connect them one by one for data processing. And the control terminal occupies a large number of IO points, the construction process is complicated and cumbersome, the required space is large, and the cost is high

[0008] 4. The traditional reverse osmosis control system is limited to transmitting data to the upper computer in the central control room through the field bus, and requires full-time operators to guard the upper computer on duty, and cannot complete remote wireless real-time monitoring anytime, anywhere

To sum up, the existing technology does not have a reverse osmosis with a high level of automation that is convenient for construction, simple in wiring, high in transmission rate, low in cost, small in footprint, easy in on-site control and maintenance, fast in fault handling, and capable of remote wireless real-time monitoring.
