Problems solved by technology

[0004] The detection of TW A CS signals is mainly based on time-domain difference technology. Most of these methods have complex data processing, poor real-time performance, and high equipment costs. In order to determine whether the signal bit is "1" or "0", due to the rigor of the calculation, the interference signal will seriously affect the judgment result of the detected signal, so the original method is difficult to apply in our country

Abstract

The invention relates to an automatic meter reading system for a tap water meter in a residential area, which comprises a main controller, a data acquisition module and each digital quantity output water meter. Each water meter can be provided with a unique number. The data acquisition module collects the measurement data of the plurality of digital quantity output water meters through the serialport and transmits the data to the main controller through power line communication; the main controller accesses the Internet through the network interface module, and the user accesses the computermanagement system of the main station by using the computer and the handheld mobile device.

Description

Technical field: [0001] The invention relates to an automatic meter reading system for tap water meters in residential areas, which includes a main controller and various data acquisition modules, adopts a power line communication method, and sends a wide pulse signal to a specific point in the area where the cycle voltage of the power grid exceeds 0 to generate a sudden change current, so that the cycle of the power grid can carry information. The main controller receives the data collected by each data acquisition module, and connects to the Internet through the network interface module integrated with the TCP / IP hardware protocol stack, so that computers and handheld mobile devices can be used to access the remote computer management system. Background technique: [0002] Current power line communication mainly refers to power line carrier communication and two-way power frequency communication. Power line carrier communication PLC uses the existing power line to transmi...
