Making use of Information Technology to Supervise and Control Environmental Pollution

[summary]

Abstract: Using high-performance NF5280M3 server and storage system, Inspur builds an automatic polluter supervisory platform with a more efficient data processing system and easier operation methods. The platform also optimizes investment outcomes by reducing management and maintenance costs.

Project Background

As stated in the "Eleventh Five-Year Program of National Economic and Social Development of People's Republic of China", GDP is expected to achieve an annual growth of 7.5% by 2010, while the energy consumption per unit GDP is expected to reduce by 20% and principal pollutants per unit GDP by 10%. In 2006, the first year of the Five-Year Program, saw 25,944,000 tons of sulfur dioxide emissions, and 14,313,000 tons of chemical oxygen demand (cod) emissions in China. Both items increased by 1.8% and 1.2% respectively compared to 2005, making the emission reduction even more challenging.

We have paid a big price of resources and environment despite of great achievements in the process of modernization of China. The country has undergone more conflicts economic development and environmental protection, and there are also widespread concerns as well as increasing public discontent regarding environmental pollution.

In order to achieve the mission of reducing emission of principal pollutants, it is urgent to establish a triplet system including a scientific emissions reduction target system, a precise supervisory system, and a strict evaluating system; only by scientific and precise calculation, supervision and evaluation is it possible to carry out emissions reduction work. In the triplet system, the automatic polluter supervisory and controlling system is of the most importance. The controlling system supervises corporations which take up to 65% of the total emissions of major pollutants in China. Furthermore, the system is also able to collect statistics of pollutant emissions, and monitor the pollutant management through automatic and informatized technologies.

Demand Analysis

The automatic polluter supervisory and controlling system consists of automatic equipment and supervision center. The automatic equipment include a flowmeter, a GPRS rtu (remote terminal unit), a set of apparatus installed in the polluting spot. These equipment record emissions and pollutants density, and also monitor the performance of pollution controlling facilities. The flowmeter records the flow of pollutants around the clock; and apparatus are responsible for real-time supervision on pollution management facilities in companies.

The supervision center is constituted by hardware and software that the department of environmental protection uses to supervise major polluters. The supervision is conducted via communication transmission lines and automatic supervisory equipment. The hardware includes servers, data receivers, display and interaction system, basic network environment, and network security system. The software comprises commercial database, operating system, a basic database for data from enterprises, an application system for supervision, a data transmission and backup system, and a network security system.

Solutions

Figure 1 and Figure 2 demonstrate the topologies of server and storage in the supervision center.

For each set of equipment, the requirements are as followed.

Since the system of the supervision center bears large amounts of real time data, the hardware needs to be efficient, stable, usable, maintainable, and extensible.

The database server: It is composed of corporate servers in a parallel-databases-cluster system, so the data possessing is stable, efficient, reliable, extensive, and maintainable. It also has remarkable manageability and flexibility, as well as outstanding capacity for data computing, exchanging, and processing. The database server also supports different kinds of redundant and reliable technology, as the Inspur 8-way-and-8-core server TS850 has 64 computing cores and 128 logic cores--which provide excellent computing capacity 40 times higher than any traditional single-core server.

GIS server: It employs middle-and-top-grade corporate servers group, and is able to handle plenty of user visits. Besides, with a 4-core processor, it has a comparatively large cache and IO network acceleration technology. Inspur 8-way-and-8-core server TS850 has 64 computing cores and 128 logic cores--which provide excellent computing capacity 40 times higher than any traditional single-core server.

Application server: It employs middle-and-top-grade corporate servers group, and is able to handle plenty of user visits. Besides, with a 4-core processor, it has a comparatively large cache and IO network acceleration technology. The application server adopts NF8560M2 with Intel E7-4800 processor NF8560M2, and the performance of all departments is remarkably high.

The automatic supervisory server: It also employs Intel E7-4800 processor NF8560M2, has a comparatively large cache, and IO network acceleration technology.  Load balancers are installed to compose web cluster. The server is also able to handle plenty of user visits.

Other servers are composed by Intel E5-2600 processor NF5280M3.

The storage: The equipment uses 8Gb all-optic-fiber disk array cabinet and high-end tape library, possesses an on-line storage capacity of over 20TB. It has power redundancy, sustainable battery, and optic-fiber hard disk that supports hot swapping. This user-friendly storage system must be built upon SAN storage and backup network.

Significance of Clients

With high-performance NF5280M3 server and storage system, Inspur builds an automatic polluter supervisory platform with a more efficient data processing system and easier operation methods. The platform also optimizes investment outcomes by reducing management and maintenance costs.

Same as the most common practice, the server's mainframe system has three tiers, namely data tier, application tier and access tier. The structure has taken all the equipment into consideration, including servers, storages, buffer memories, and the width of I/O band, in order to keep the data secure, concentrated and instantaneous. The system not only meets the requirements of centralized management, unified data storage and backup, but also provides an extensible and flexible platform for following-up projects in the future.

We have achieved the following goals:

Collecting, processing and assembling original data;

Building a data center for automatic supervision and management;

Exchanging data between local systems and the center;

Realizing automatic supervision and to assist leaders in policy making.
