1、 System background:

The 2014 Qingdao World Horticultural Exposition is a non trade exhibition displaying the world's horticultural products and scientific and technological achievements. It is known as the "Olympic event" of the world's horticultural culture and garden science. As the total planning area of Qingdao International Horticultural Exposition Park of this Expo is as high as 241 hectares, and the main building venues such as theme pavilion, Tianshui Dichi area and botanical pavilion have certain requirements for water quality, our company has successfully developed and designed water quality monitoring system for this World Horticultural Expo.

According to the requirements of Qingdao World Expo, the water quality monitoring points of the Expo will realize real-time monitoring of nine parameters, such as permanganate, total phosphorus, total nitrogen, ammonia nitrogen, pH, dissolved oxygen, conductivity, turbidity and temperature, and alarm when the water quality exceeds the limit, so as to ensure the water quality during the Expo.

2、 System composition

The water quality monitoring system of Qingdao Garden Expo is mainly composed of on-site telemetry unit, central server and remote customer monitoring. Based on GPRS wireless network, the water quality monitoring during the Expo is realized.

The hardware of the system is the field telemetry unit and the remote customer monitoring terminal.

The system software is server software and client software.

The overall scheme deployment diagram of the water quality monitoring system of the Qingdao Garden Expo is as follows:

4、 System function

According to the requirements of Qingdao Horticultural Expo, the water quality monitoring system of Qingdao Horticultural Expo has the following functions:

1. Remotely control the opening and closing of submersible pump for water intake analysis;

2. Real time monitoring of water quality changes, including the following parameters: permanganate, total phosphorus, total nitrogen, ammonia nitrogen, pH, dissolved oxygen, conductivity, turbidity, temperature and other nine parameters;

3. After the water quality exceeds the limit, the water quality alarm can be carried out;

4. Alarm methods include: software alarm and SMS alarm;

5. Realize Map GIS display;

6. Realize the dynamic display of the overall structure of the system;

7. Realize the function of historical data statistics;

8. Realize multi-user and multi authority allocation.

5、 System hardware

The hardware of the water quality monitoring system of Qingdao Garden Expo is mainly divided into two parts: remote customer monitoring terminal and on-site telemetry unit.

The remote client monitoring end is a camera;

The field telemetry unit is mainly composed of field control box, permanganate detector (seres 2000), total phosphorus and total nitrogen (hash) detector, (pH, dissolved oxygen, conductivity, turbidity, temperature) detector, k301a detector, etc.

1. The field control box is located between the sensor and the central server, which is responsible for data acquisition and transmission. The main equipment is the RTU remote measurement and control terminal of our company.

2. Permanganate detector (seres 2000) is used to monitor the permanganate concentration of water quality;

3. Total phosphorus and total nitrogen (hash) detector is used to monitor the content of total phosphorus and total nitrogen;

4. (pH, dissolved oxygen, conductivity, turbidity, temperature) and other detectors are used to detect and monitor five water quality parameters such as pH, dissolved oxygen, conductivity, turbidity and temperature;

5. K301a detector is used to monitor the current ammonia nitrogen content.

6、 System software

The water quality monitoring system software of Qingdao World Horticultural Expo adopts CS architecture, which is divided into server software and client software.

Among them, the server software and deployment shall be installed and debugged by our special personnel in the early stage, and the later server maintenance shall also be maintained by our special personnel.

The client software is sent to customers by our company in the form of CD-ROM and e-mail.
