summary:

Hydrological monitoring system is an important part of national economic infrastructure. It plays an irreplaceable role in flood control, drought resistance and disaster reduction, water resources development and utilization, water ecology and environmental protection, water engineering planning and operation management.

Especially in flood control and disaster reduction, hydrological monitoring plays a role of ears, eyes and vanguard. Accurate and timely rain and water information and prediction provide a basis for scientific decision-making and real-time dispatching of government departments.

Hydrological monitoring system is an unattended hydrological data acquisition system integrating hydrological data acquisition, storage, transmission and management. The hydrological monitoring station system consists of hydrological sensor, data acquisition instrument and computer software.

The data acquisition instrument has the functions of hydrological data acquisition, real-time clock, hydrological data timing storage, parameter setting, friendly man-machine interface and standard communication.

Large capacity memory chip is built in the system; A variety of communication interfaces can easily establish wired communication connection with the computer. If GPRS wireless communication module is selected, it can also realize the remote wireless connection between hydrological equipment and computer monitoring center.

Monitoring system functions:

◆ real time monitoring of rainfall, water level, water quality temperature, water quality osen value, water quality salt conductivity, water quality dissolved oxygen and other element monitoring parameters;

◆ microcomputer monitoring data acquisition instrument has the functions of meteorological data acquisition, real-time clock, timing storage, parameter setting, power failure protection of parameters and meteorological historical data, etc;

◆ Chinese character LCD keyboard has friendly man-machine interface;

◆ data browsing function. It can provide LAN data browsing, Internet data browsing, mobile phone data browsing and other data browsing ways for users to choose;

◆ flexible system networking mode. The communication function supports Modbus communication protocol. Provide standard wired, wireless and other communication modes for users to choose. It is flexible to form a meteorological monitoring system with meteorological computer;

◆ reliable power supply system. Provide various power supply modes such as municipal power supply, DC and solar energy system for users to choose;

◆ all stainless steel, metal spray paint support and field protection box are adopted, with beautiful appearance, corrosion resistance and anti-interference.

Monitoring system features:

◆ power supply system: dual power supply system, AC 220V, DC 5V, 12V, solar energy, etc., which can be selected according to the needs of users.

◆ reliable operation in various harsh field environments, low power consumption, high stability, high precision and unattended.

◆ perfect lightning protection, anti-interference and other protection measures.
