1. Principle of system components: 

2. Overview:
Concentration of residents low-voltage meter reading system using computer and advanced communication technology and the high-speed MCU terminals together constitute the system.The system has full of features, new technologies and strong compatibility, meter reading large capacity (Can meet more than 1000 Community, and can be cascaded), reliable operation and low operating and maintenance costs； for the power companies saving manpower, time and vehicles using the fee, more importantly, it has a function of highly efficient, accurate and fast to realization of meter reading, to really achieve the automated meter reading!

3. System design features:
the main station using redundancy to eliminate single equipment failure caused the loss of important functions.
Systems availability year theory is greater than 99.99% .
System with hot and cold start function.
Solid and strong real-time integration of system events to provide fast and constant responsiveness, in an efficient, fast, reliable and accurate way to reflect the system events.
Computer with high utilization.
System uses object-oriented support platform and operating, development platforms, improve software reliability, inheritable, maintainability and scalability.
High security, using dual-network configuration and split / dual network redundancy mechanism, an important node in a dual redundant hot standby machine to improve system reliability and stability.
Easy to maintain, the device has self-checking and on-line diagnostic and calibration capabilities, the system can be made with a convenient data backup and restore functions, the system should have remote maintenance, debugging and diagnostics.

4. System Function Description:
