Automatic control system for shiitake mushroom culture room

Abstract

The invention provides an automatic control system for a shiitake mushroom culture room. The automatic control system comprises a master control upper computer, a PLC air conditioner controller, an air conditioner terminal, an ABB frequency converter, a CO2 transmitter, a fresh air valve and an air return valve. By setting various parameters on a touch screen, other terminal equipment such as an air conditioning unit, the frequency converter, the fresh air valve and the air return valve can be controlled, and aiming at the problem that the temperature of the room is not uniform, automatic turbulent flow can be achieved according to the temperature difference between the upper temperature and the lower temperature of the room, and regular turbulent flow can also be achieved. In order to solve the problem that a large amount of CO2 can be generated in the cultivation period of shiitake mushroom sticks, the CO2 concentration is detected, the fresh air valve, the air return valve, an exhaust fan and the like are automatically started according to set values, fresh air is automatically exchanged, high-concentration CO2 in the room is discharged outdoors, a timing fresh air exchange function can also be started, and fresh air is exchanged once every certain time. The automatic control system has an automatic air cooling function, if the environment temperature is far lower than the indoor temperature, equipment can be automatically converted into an air cooling mode, and therefore a large amount of energy is saved.

Description

technical field [0001] The invention relates to the technical field of automatic control systems, in particular to an automatic control system for mushroom cultivation rooms. Background technique [0002] With the continuous improvement of people's living standards, people's demand for shiitake mushrooms is also increasing. In the past, the cultivation of shiitake mushroom sticks was generally done in spring and autumn every year. Due to the large temperature difference between day and night, the cultivation time of mushroom sticks Too long, and the success rate and fruiting rate are not high. Summer and winter simply cannot be done due to the weather. With the development of science and technology, people began to use air conditioners to cultivate the mushroom sticks, so that the mushroom sticks can be cultivated all year round. The conventional control method is: use the cooling and heating function of the air conditioner to keep the room temperature constant, and start ...
