Automatic control system for vegetable greenhouse

Abstract

The invention discloses an automatic control system for a vegetable greenhouse. The system comprises a controller, a sprinkling irrigation device and a fertilization device which are electrically connected with the controller, a mobile information center communicating with the controller through a wireless network, and a sensor for transmitting information with the mobile information center through a GPRS network. The automatic control system for the vegetable greenhouse provided by the invention utilizes the vegetable greenhouse constructed by an agricultural internet, and can provide an advanced technology of effectively controlling the growth environment of vegetables for greenhouse planting, so that the vegetables obtain the best growth environment, and the yield is increased to realize cross-season vegetable cultivation.

Description

technical field [0001] The invention relates to an automatic control system, in particular to an automatic control system for vegetable greenhouses, belonging to the field of agricultural information technology. Background technique [0002] Agricultural Internet is the specific application of Internet technology in agricultural production, operation, management and service; according to the Internet technology architecture, agricultural Internet still realizes the application of agriculture through the way of perception-transmission-application; perception is the use of various sensors, such as Temperature and humidity sensor, light intensity sensor, PH value sensor, CO 2 Sensors and other equipment, real-time collection of temperature, humidity, PH value, light intensity, soil nutrients, CO 2 Concentration and other physical quantity parameter information; transmission is to establish data transmission and conversion methods, through local wireless networks, the Internet,...

[0002] Agricultural Internet is the specific application of Internet technology in agricultural production, operation, management and service; according to the Internet technology architecture, agricultural Internet still realizes the application of agriculture through the way of perception-transmission-application; perception is the use of various sensors, such as Temperature and humidity sensor, light intensity sensor, PH value sensor, CO 2 Sensors and other equipment, real-time collection of temperature, humidity, PH value, light intensity, soil nutrients, CO 2 Concentration and other physical quantity parameter information; transmission is to establish data transmission and conversion methods, through local wireless networks, the Internet, mobile communication networks and other communication networks to achieve effective transmission of agricultural production environment information; application is to obtain a large number of agricultural The information is fused and processed, enabling technicians to monitor, control and intelligently manage the environment of multiple greenhouses, ensuring a good and suitable growth environment for crops, achieving the purpose of increasing production, improving quality, adjusting growth cycle, and improving economic benefits. In order to achieve the goals of intensive agricultural production, high yield, high quality, high efficiency, ecology and safety; although the agricultural Internet technology is gradually mature, the agricultural Internet has broad prospects in the application of agricultural development, but the application cost of Internet technology is relatively high. For low-efficiency agriculture, there is obviously a problem of difficulty in marketing, so Internet technology is more commonly used in facility agriculture
