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 agricultural greenhouse climate control system which is composed of area controllers and a master station controller. Each area controller controls one or multiple agricultural greenhouse(s), and comprises data collectors and electric appliance controllers. Each data collect transmits collected humidity and temperate data to the corresponding area controller for processing via power line communication, each electric appliance controller receives an instruction from the area controller to control work of electric appliances as a furnace and a pump also via power linecommunication, and the area controller accesses the Internet via a network interface module. A manager can control operation of the system via a handheld computer.

Description

(1) Technical field: [0001] The invention relates to a climate control system for agricultural greenhouses, which includes a regional controller, various data collectors, and an electrical appliance controller, and uses a power line communication method to send a wide pulse signal to a specific point where the grid cycle voltage crosses 0 to generate a sudden change current, so that the grid cycle voltage carry information. The regional controller receives the data collected by each data collector and electrical controller, 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. (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 ...
