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 artificial climate experiment control system for an agricultural greenhouse. According to the invention, the temperature, humidity, illuminance, carbon dioxide concentration and the like in each greenhouse are controlled according to experimental requirements; a main controller and sensors and execution controllers corresponding to the temperature, humidity, illuminance, carbon dioxide concentration and the like are arranged in each greenhouse for controlling the climate of the greenhouse in a set value range; the execution controllers and measuring instruments communicate with the main controller through electric lines; and the main controller accesses a mobile wireless communication network through a 4G wireless router.

Description

(1) Technical field: [0001] The invention relates to an artificial climate experiment control system for agricultural greenhouses, which includes a main controller and various measuring instruments, 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 current, which is used as a bit value of the signal , the main controller receives the data collected by each measuring instrument, and connects to 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 carr...
