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

[0052] A block diagram of the circuit structure of a measurement and control system for an aquaculture nursery base figure 2 shown. It consists of a centralized controller and multiple measurement and control 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 measurement and control instrument is composed of a signal sending terminal A, a signal receiving terminal B and a microcontroller module 1 , and the measurement and control instrument controls the action of the execution device 7 . The centralized controller communicates with the measurement and control instrument through the power line. The terminal is the computer management system located on the top layer, which is composed of 4G wireless router, microcontroller module and computer.

Abstract

The invention relates to a measurement and control system for aquaculture seedling raising bases. Water temperature,air temperature and other change conditions need to be observed for a long time forsome large-scale aquaculture or seedling raising experimental bases,if an abnormality occurs,alarm processing is conducted in time,and a measurement and control instrument starts corresponding execution equipment to restore measured parameters within a set value range. Each monitoring area is provided with a centralized controller,the measurement and control instrument uploads measured data to thecentralized controller through power line communication,and management personnel use a mobile phone APP and a computer to access a computer management system of a main station and know the conditionsof all the monitoring areas.

Description

(1) Technical field: [0001] The invention relates to a measurement and control system for an aquaculture nursery base, which includes a centralized controller and various measurement and control instruments, adopts a power line communication method, and sends a wide pulse signal to a specific point where the cycle voltage of the power grid crosses 0 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 measurement and control 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 ...
