The Polluted Water Treatment Automation
The Background
With the strengthening of urbanization construction, big cities accelerate in
construction , small and medium cities expand faster and faster,there are many
changes for municipal sewage treatment plants, whether from process level or through
put capacity of sewage treatment.
Computer software technology,communication technology,automation control play
important supportive role in the sewage treatment,However Communication network
is the most basic and most key part in this system.Sewage treatment needs to prevent
all kinds of interference, therefore industrial grade network equipment is a must.
Also, as the equipment are widely distributed and are often located in harsh
environment, the best choice would be wireless TCP/IP modem
The challenge
1.The polluted plant environment harmful to human health
2.How to analyze many polluted elements and contents
3.How to reduce maintenance fee and time cost
The solution
Based on the requirements of sewage treatment, we provided GPRS based solution.
SignShine DTU can be connected with concentrator by RS485 or PLC directly,it has GPRS Simcard inserted which can communicate via mobile wireless network.
Through TCP/IP stack it is easy and safe to transfer data from site to data center.It has RTC for automatic self check and re-connect the server.
Benefits of the solution:
1.Easy to deploy network and all the sewage plant covered.
2.Secure channel for PLC data communication,real time data transmission.
3.Mistakes avoided by human error and labor costs saving
Key benefits of SignShine DTU:
1.Industrial design and wide voltage power supply design for harsh environment.
Wide operation temperature: -25~60℃
Power input: 7-32V DC
EMC&EMI test passed
2.OS with MMU(memory management unit)for fast data processing.
3.Support several work mode and protocols,customized firmware supported.
