Description

Temperature sensor-based temperature control method and system for fungus culture environment Technical Field The invention relates to the technical field of intelligent agriculture and environmental control, in particular to a temperature sensor-based temperature control method and system for a fungus mushroom culture environment. Background In the field of fungus culture, maintaining stable proper temperature is a core environmental factor for guaranteeing healthy growth of hyphae, primordial differentiation, high quality and high yield of fruiting bodies. The traditional fungus mushroom cultivation environment temperature control method is mostly dependent on temperature sensors arranged in single or few points in a cultivation space, and based on obtained local temperature readings, the whole cultivation area is uniformly regulated and controlled through a general PID control algorithm. A global target temperature value is usually preset, and an environmental control device such as a central air conditioner, a fan heater or ventilation equipment is driven to start and stop operation so as to try to maintain the average temperature of the whole cultivation space within a set range. A method for improving the uniformity of the buds of bottle-cultivated pleurotus eryngii, for example, the patent publication No. CN103999689A, relates to the technical field of pleurotus eryngii cultivation, and comprises the steps of introducing the bottle-cultivated pleurotus eryngii into a mushroom cultivating chamber after mushroom scratching treatment, closing ventilation and illumination of the mushroom cultivating chamber to enable the mushroom cultivating chamber to be in a closed dark condition, adjusting the temperature to 8-10 ℃, improving the relative humidity to 95%, maintaining the temperature for 24 hours in the cultivating environment, then improving the temperature to 16-18 ℃, adjusting the illumination to be on for 30 minutes every 60 minutes, and enabling the ventilation volume to be based on the condition that the indoor carbon dioxide concentration is maintained to be 2000ppm, and promoting the buds for 5-8 days. The precise regulation and control device for the flammulina velutipes strain culture environment disclosed in the patent publication No. CN120530843A and the intelligent control method thereof comprise a flammulina velutipes strain culture box body, wherein the outer wall of the top of the flammulina velutipes strain culture box body is fixedly connected with an air inlet pipe in a penetrating mode, the outer wall of the bottom of the air inlet pipe is fixedly connected with an installation shell, the outer wall of one side of the flammulina velutipes strain culture box body is fixedly connected with a controller, the outer wall of one side of the flammulina velutipes strain culture box body is fixedly connected with a motor, and the outer wall of the other side of the flammulina velutipes strain culture box body is fixedly connected with a water tank. The angle of the heating plate is adjusted by the motor, so that the propagation direction of heat can be changed, the heat can more uniformly cover each horizontal area of the flammulina velutipes strain incubator body, all flammulina velutipes strains are ensured to be in a similar temperature condition, the flammulina velutipes strains can uniformly grow, and the angle of the heating plate can be freely adjusted by staff according to the field requirement. However, in the process of implementing the technical scheme of the embodiment of the application, the application discovers that the above technology has at least the following technical problems: As obvious temperature field heterogeneity caused by factors such as equipment layout, uneven air circulation, external environment influence and the like often exists in the mushroom culture space, the readings of a few sensors cannot accurately reflect the real temperature distribution of each point in the space, and the temperature of a local area is easy to be out of control. Meanwhile, the whole space is regarded as a homogeneous unit to be uniformly regulated and controlled, so that dynamic response characteristic differences possibly existing in different areas due to different distances from a heat source/a cold source are ignored, regulation and control response delay and energy consumption are increased, and fine control is difficult to realize. Disclosure of Invention The application provides a temperature sensor-based temperature control method and system for a fungus culture environment, which are used for solving the technical problems of low reliability and strong hysteresis of environmental temperature control caused by lack of deep analysis of temperatures of different areas in a fungus culture space in the prior art.
