GPRS Water remote automatic meter reading system Solution

GPRS Water remote automatic meter reading system Solution

1 . Introduction

As the departments of water supply for the reconstruction of "one household one table", as well as the requirement of automation, a remote automatic meter reading system has become water automation management and an indispensable part of intelligent control.In order to adapt to the water supply company user water meter and the need of modern intelligent building water management, convenient water meter users pay the water fee, the xiamen CAIMORE technology communication specially designed for water supply companies, property management companies based on GPRS wireless network tap water remote automatic meter reading system.The system will be computer technology, mobile data communications technology, network technology, automatic control technology to dissolve into an organic whole, can automatically complete water meter network and remote data acquisition, records, real-time monitoring, statistical analysis, print, and for, water control management work.3

2 . Components

Water remote automatic meter reading system consists of monitoring center, communication networks and wireless networks meter (digital water meter + CM3150P DTU) components. It comprises a central station monitoring center, computer and system software, monitors, printers and other equipment, the central station computer communication with the use of a wireless network meter China Mobile's GPRS network. The system is suitable for the water company vast distances, dispersed separate water meter users, system network block diagram shown in Figure




3 . Function

3.1, the automatic detection function: the system for water meter (flow) and other parameters (pressure) data collection, monitoring, recording, and data analysis and processing, the formation of a variety of graphs and reports, remote unmanned automatic meter reading.

3.2, dynamic display function: timed or random dynamic display network automatic meter reading system drawing surface water per meter and the entire system including the total amount of water meter.

3.3. Printing: You can print each meter monthly, annual reports and monthly water bills, the total water consumption can print day, month, annual reports and monthly charge for water, annual reports.

3.4, data management functions: establish historical database to store raw data for statistical analysis. Analysis of calculation of water consumption and other data collected cumulative, average, maximum, minimum and so on, the system database for the expansion and maintenance of all sizes to meet the water meter reading and maintenance department data use.

3.5, mergers, web browsing functions: The system can be connected to the water supply company's servers, local area network access through the company's existing water supply business charge computer management system, to achieve information sharing.

3.6, automatic bank payment: through the monitoring center management system and bank charges mount, billing flexibility.

3.7, the case can be based on user pay water supply or water control, IC card having a support function.

4 . Main equipment

4.1, the central station machine: instructions for sending the monitoring center computer and receive wireless network meter information, and information through the RS-232 / RG45 communication interface into the computer.

4.2, the system software:

System development of professional software, which combines software with the latest international fashion trends, can run on Windows98, Windows2000, WindowsXP, Liunx other mainstream operating systems. System software release machine instructions by the central station, monitoring the implementation of the system, is responsible for configuration and network management of the collection site, while the input data into the database, you can issue commands to achieve parameter setting, data monitoring, statistical analysis and report printing and supply , water control and other treatment.

4.3, CM 3130P GPRS DTU Technical parameters:CM 3150P GPRS DTU using high-performance industrial embedded ARM9 processor, real-time operating system software support platform, large memory, built-in proprietary TCP / IP protocol stack. To provide users with high-speed, reliable, always-on data terminals, multiple protocol conversion of a virtual private network. For user-network flow control products support voice, messaging, data and on-line trigger automatic disconnection timeout function. Also supports dual data center backup, and synchronize multiple data centers to receive data, and other functions.
