LPC2132 single-chip microcomputer-based closed henhouse environment control system

Abstract

The invention discloses an LPC2132 single-chip microcomputer-based closed henhouse environment control system, including a data transceiver and a power module and an RS232 / 485 communication module connected with the data transceiver and used for serial data transmission communication. An input end of the data transceiver is connected with a light intensity sensor circuit, a keyboard input circuit, an H2S sensor circuit, an NH3 sensor circuit, a CO2 sensor circuit and a temperature and humidity sensor module; an output end of the data transceiver is connected with a liquid crystal display circuit, a sound-light alarm circuit used for alarm reminding, an electric ball valve circuit and a wet curtain fan circuit; and the temperature and humidity sensor module includes a temperature and humidity sensor circuit and an I2C bus connected with an output end of the temperature and humidity sensor circuit to be used for transmitting multipath data. The LPC2132 single-chip microcomputer-based closed henhouse environment control system has the advantages that the system is simple in structure, a controller can rapidly respond to an environment change, automatically adjust a solenoid valve switch to control spray and automatically control a wet curtain fan to ventilate and dry environment, and the practicability is strong.

Description

technical field [0001] The invention belongs to the technical field of aquaculture production, and in particular relates to a closed chicken house environment control system based on an LPC2132 single-chip microcomputer. Background technique [0002] Nowadays, the development scale of the laying hen farming industry is getting larger and larger, and the number of laying hens is also developing towards concentration. The growth of laying hens also requires higher and higher environmental control, which is a factor that directly affects the survival rate of laying hens, such as indoor temperature, humidity, light, carbon dioxide, ammonia and hydrogen sulfide and other gases. The survival rate of chickens has a great influence. The traditional chicken house environment controller takes a long time to collect sensor data and single-chip data processing, and then manually control a series of measures such as ventilation, cooling, ventilation, heating and humidifying the chicken ...

AI Technical Summary

Problems solved by technology

The traditional chicken house environment controller takes a long time to collect sensor data and single-chip data processing, and then manually control a series of measures such as ventilation, cooling, ventilation, heating and humidifying the chicken house to change the environment, and the whole is still in a semi-automatic control system

Due to the need for people to implement regulation, it is prone to some negligence, failure to take timely measures, resulting in economic losses, and cannot quickly respond to environmental changes. Nowadays, there is a lack of a simple structure, reasonable design, safe and portable, real-time monitoring on the market. Data information and the controller can quickly respond to environmental changes, automatically adjust the solenoid valve switch to control the spray and automatically control the wet curtain fan to ventilate and dry the environment, and can make corresponding adjustments. It has complete functions, data storage function, and good use effect. The chicken house environmental control system can ensure an excellent growth environment for laying hens, solve the problem that the chicken house environmental control system is in a semi-automatic mode that requires manual operation, and improve the survival rate of laying hens.
