Problems solved by technology

[0006] 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

[0059] A block diagram of the actual circuit structure of a vegetable greenhouse climate control system is as follows figure 2 shown. Including the main controller and multiple data collectors, electrical controllers. The main controller is composed of a signal sending terminal A, a signal receiving terminal B, a keyboard display module 10, a microcontroller module 1, and a CC2530 module 2. The main controller with radio frequency communication is equipped with CC2530 module 2. 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 main controller communicates with the data collector and the electrical appliance controller through the power line. The electrical controller is to control the execution of electrical work.

Abstract

The invention relates to a vegetable greenhouse climate control system. The system comprises master controllers, all data collectors and electrical controllers. A power line communication method is adopted to send a broad-pulse signal to a specific point in a region, where voltage exceeds zero, of a power grid cycle so as to generate a surge current, and therefore the power grid cycle carries information. The master controllers receive data collected by all the data collectors and the electrical controllers, each of different transformer courts selects one adjacent master controller to installa Zigbee module so as to realize radio frequency wireless communication, and therefore converging of collected signals in each master controller is realized.

Description

[0001] (1) Technical field: [0002] The invention relates to a vegetable greenhouse climate control system, which includes a main controller, various data collectors, and electrical controllers, 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 carry information. The main controller receives the data collected by the data collectors and electrical controllers, and selects an adjacent main controller for each transformer area to install a Zigbee module to realize radio frequency wireless communication, so as to realize the collection of collected signals in each main controller. [0003] (two) background technology: [0004] 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 throug...
