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

Embodiment Construction

[0053] The circuit structure block diagram of a sewage discharge monitoring and alarm system is as follows: figure 2 shown. It consists of a centralized controller and multiple flow measuring instruments. The centralized controller is composed of a signal sending end A, a signal receiving end B, a 4G wireless router 2 , a keyboard display module 10 and a microcontroller module 1 . The flow measuring instrument is composed of a signal sending end A, a signal receiving end B, a digital flow meter 7 and a microcontroller module 1 . The centralized controller communicates with the flow measuring instrument using the power line. The terminus server is the computer management system located on the top layer, which is composed of 4G wireless router, microcontroller module and computer.

Abstract

A system for monitor and alarming sewage discharge is provided. Many enterprises in the industrial zone discharge large quantities of sewage into the rivers, at this time, a monitoring system is need,a digital flow meter is arrange at each sewage discharge outlet, a centralized controller and a plurality of flow measuring instruments are arranged at each monitoring alarm area, and the flow measuring instruments arrange the collected flow data and transmit the collected flow data to the centralized controller for processing through power line communication. When the value of liquid flow exceeds the limit, that is, an alarm is given to the computer management system through the mobile wireless communication network, the manager can go to the scene to check the situation.

Description

(1) Technical field: [0001] The invention relates to a sewage discharge monitoring and alarm system, which includes a centralized controller and various flow measuring instruments, and uses a power line communication method to send a wide pulse signal to a specific point in the grid cycle voltage crossing 0 area to generate a sudden change current, which is used as a bit value of the signal, The centralized controller receives the data collected by each flow measuring instrument, and accesses the 4G mobile wireless communication network through a wireless router, so that mobile phones, computers and handheld mobile devices can be used to realize wireless networking no matter where they are. (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 dis...
