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 block diagram of the circuit structure of an intelligent control system for temperature and humidity in agricultural greenhouses is as follows: figure 2 shown. It consists of a regional controller, multiple data collectors, and electrical controllers. The regional 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 . Both the data collector and the electrical appliance controller include a signal sending terminal A, a signal receiving terminal B and a microcontroller module 1 , wherein the data collector also includes a temperature and humidity sensor 11 . The electrical appliance controller controls the execution of electrical appliances, and the regional controller communicates with the data collector and the electrical appliance controller through the power line. The total station controller is the computer management system located on the top layer, wh...

Abstract

The invention relates to an intelligent control system for the temperature and humidity of an agricultural greenhouse, and the system consists of regional controllers and a master station controller.Each regional controller controls one or more agricultural greenhouses, and consists of a plurality of data collectors and a plurality of electric appliance controllers. Each data collector is connected with one or more temperature and humidity sensor, and the data collectors transmit the collected temperature and humidity data to the regional controllers for processing through power line communication. The electric appliance controllers receive the instructions of the regional controllers through the power line communication for controlling a furnace and a pump to perform electrical operations. A manager can control the operation of the system through a cellphone APP.

Description

(1) Technical field: [0001] The invention relates to an intelligent temperature and humidity 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 cycle voltage of the power grid passes through 0 to generate a sudden change of current. The bit value of the signal, the regional controller receives the data collected by each data collector and electrical appliance controller, 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. The device implements 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 commun...
