Problems solved by technology

Due to the use of dedicated line communication, the wiring is complicated and the cost is increased. If the timing time is not corrected through the line communication, due to the traditional timing error, after several hours of operation, the accumulated timing error will make the system control action inconsistent, which may cause the system to collapse. In some occasions where the design is changed frequently and the amount of wiring engineering is large, the product application is limited

Abstract

The invention relates to an automatic meter reading system for a tap water supply network. The system comprises a plurality of water meters, a plurality of controllers and a master controller. The water meters transmit measured data to the controllers in a communication mode through power lines, and the controllers carry out scanning and registering on the water meters regularly and give an alarm to a management center when finding faults. Step time is adopted to the water meters, the controllers of the water meters and the master controller so that system actions can be consistent.

Description

(1) Technical field: [0001] The invention relates to an automatic meter reading system for tap water supply pipe network. The system includes multiple water meters, controllers and a main controller. Each water meter transmits measurement data to the controller through power line communication, and each controller regularly scans each water meter. Register, and report to the management center when faults are found. All water meters and their controllers and master controllers adopt synchronous time to keep the system consistent. (two) background technology: [0002] In the control system that is powered by the power grid, each electronic device or module communicates through a dedicated line to correct the timing time of each electronic device or electronic module to achieve the purpose of synchronous operation. Due to the use of dedicated line communication, the wiring is complicated and the cost is increased. If the timing time is not corrected through the line communicat...
