Facility Automation Qinhuangdao Port, China

Project Introduction: Qinhuangdao Port is a strategically important port in China and is the largest coal shipping port in the country, much of which is shipped to power plants elsewhere in China . With recent expansion, its capacity has reached 209 million metric tons. The harbor is also adding a further six berths to add further capacity and is increasingly being invested in by other port operators. The formation of the Qinhuangdao sewage treatment system goes back to 1980. This system includes Qinhuangdao sewage treatment plant and an oxidation pond. In order to meet the plant automation requirements, a complete automation control system, including data acquisition and monitoring was required.

System Requirements:
The main control center is located at outskirts of the city, far away from the remote site and with many hazardous field conditions. Moreover, the plant had adopted a wide range various brands of equipment, including Siemens S7-400 and S7-200 controllers. This led to the following requirements:

• Real-time monitoring of various parameters, such as process flow, water level, flow volume, and water pressure
• The Control interface needs to be able to switch between manual and automatic operation.
• Real-time data needs to be transmitted across multiple remote locations
• Access to monitoring data and other operations need to be granted based on different access levels to not only prevent the system from unauthorized operation, but also reduce the mistaken operation
• Daily report should be printed automatically, while monthly and yearly report should be printed manually.

Project Implementation:

	Advantech WebAccess
	IPC-610 industrial computer
	EKI series industrial switch

System Description:
EKI-2525P PoE switches are connected to control rooms within the building, and then connect to SINELINK transmitters, (WiMAX wireless data links designed by Hitachi), providing them power and data through the Ethernet cable. This frees Hitachi from having to run additional power lines to the roof for the switches and transmitters. This elegant solution not only saves costs, but also significantly streamlines the entire system.

Conclusion:
Advantech’s PoE switches are allowing this revolutionary system to be implemented across Japan with the need for installing thousands of additional new power lines as well. They also provide Hitachi the following additional benefits:

• Reliable PoE capabilities allowing Hitachi to realize an expansive Wireless communication system
• They work reliably in humid and dusty environments, under wide operating temperatures
• Their industrial-grade design and easy mounting capabilities provides easy installation and maintenance
