Due to the need for cross regional or even cross city management, water companies, large enterprises and other units cannot meet their real-time meter reading requirements by using manual close range wireless reading. To meet this demand, an intelligent network collection terminal based on GPRS wireless large caliber water meter centralized meter reading solution can be adopted. The intelligent network collection terminal solution consists of three parts: a large-diameter water meter, a GPRS collection module, and a management system. The data measured by the large-diameter water meter is saved at the time interval set by the system, and the water meter data can be connected to the Internet through GPRS/CDMA channels according to the pre-set reporting cycle, and automatically transmitted to a data center computer with a fixed IP for data storage, statistics, and analysis through integration with the management system.

Specification and technical parameters of intelligent network collection terminal

The intelligent network collection terminal adopts GPRS communication technology with real-time online characteristics. The system has no delay and can synchronously receive and process data from multiple data collection points, dynamically monitoring the working status of large-diameter water meters;

The intelligent network collection terminal collection module adopts a high-pressure sealed cabin design, and the joint part adopts IP68 waterproof components, suitable for the working environment inside the water meter well;

Adopting a module that does not require external power supply and a dual backup battery design, it ensures that data is never lost. The built-in high-energy lithium battery in the acquisition core can guarantee operation for more than 6 years, and the external large capacity replaceable battery can work continuously for about 3.5 years with a 2-hour active reporting cycle

The intelligent network collection terminal supports multi-channel collection and can collect and manage 4 water meters in a unified pipeline well;

Support local setting of RS485 interface, allowing for both local and remote settings, facilitating maintenance and reducing the workload of equipment debugging, maintenance, and repair;

The data transmission rate is high, and the theoretical transmission rate of GPRS network can reach 171.2kbit/s. The actual transmission rate is 40Kbps, and the communication cost is low. Users can choose to use unlimited monthly or annual data packages according to their situation;

The intelligent network collection terminal is easy to install and use. Only one 485 bus connection is needed between the GPRS collection module and the water meter, and it is equipped with a serpentine sheathed wire;
