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 a flow data acquisition system. A centralized controller and a plurality of flow measurement instruments and digital quantity flowmeters are arranged in each of monitoring areas, wherein each of the flow measurement instruments is used for acquiring liquid flow data of the plurality of digital quantity flowmeters at set synchronous time; and the flow measurement instruments are used for arranging the acquired flow data and transmitting the data to the centralized controller through a power line in a communication manner for processing. The centralized controller is accessed to 4G mobile wireless communication network through a wireless router, so that the liquid flow data of each monitoring area can be known anytime by using a mobile phone APP, a computer or a handhold mobile device everywhere.

Description

(1) Technical field: [0001] The invention relates to a flow data acquisition system, which includes a centralized controller and various flow measuring instruments, and adopts the power line communication method to send a wide pulse signal to a specific point in the power grid cycle voltage crossing 0 area to generate a sudden change current, which is used as a bit value of the signal, and centralized The controller receives the data collected by each flow measuring instrument, and accesses the 4G mobile wireless communication network through a wireless router, so that no matter where you are, you can use mobile phones, computers and handheld mobile devices to realize wireless networking. (two) background technology: [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 transmit signals through carrier wave. However, the distr...
