A mathematical modeling and control method for edible fungus greenhouse environment, setting data acquisition mechanism, data processing mechanism and action execution mechanism, and establishing an objective function based on four factors of temperature, humidity, carbon dioxide concentration and illuminance in the data processing mechanism Model and real-time function model, according to the deviation factor and degree of deviation between the objective function model and the real-time function model, the corresponding control mode of the action actuator is activated to complete the real-time regulation of the environment of the edible mushroom greenhouse. Through the collected production environment data of the historical edible fungus room, comparative study of the influence of temperature, humidity, CO2 concentration and light intensity on the yield and quality of edible fungus, a new control model was created to control the temperature, humidity, CO2 and light of the fungus room, The central overall control adjustment is carried out so that the edible fungus is always in the best growth environment, and the control of the model and control correction can be carried out according to the actual needs. It provides multi-directional guidance for the environmental regulation of edible mushroom greenhouses.

The invention discloses a built-in railway wheel pair turntable with worm and gear driving rotation, and relates to the technical field of railway vehicle wheel pair production and maintenance equipment. The turntable comprises a bottom plate; and a driving motor and a lifting mechanism are fixed on the bottom plate; the bottom end of the lifting mechanism is fixed on the upper surface of the bottom plate, and a supporting plate is fixed to the top of the lifting mechanism; and a vertical column is installed on the supporting plate, and a worm wheel is arranged on the outer side of the vertical column in a rotating fit manner through a bearing; the top end of the worm wheel is fixedly connected with a turntable through a connecting plate; a worm for driving the worm wheel to rotate is further arranged on the supporting plate, and one end of the worm is connected with a motor; a proximity switch is fixed on the supporting plate, and a plurality of sensing blocks which are in induction fit with the proximity switch are uniformly distributed on the bottom side face of the turntable. According to the turntable, the rotation is carried out through ascending and descending of the liftingmechanism controlled by the driving motor and the rotating structure composed of the worm and gear controlled by the motor correspondingly, so that the lifting and rotating directions of the turntable can be controlled and adjusted.

The invention discloses a controlling and adjusting device for a printing range of a three-dimensional material additive printer. The controlling and adjusting device comprises a printing spray head mounting base and a controlling and adjusting mechanism, wherein the controlling and adjusting mechanism comprises a first moving rod, a second moving rod, a third moving rod, a mounting rack, a firstdriving piece, a second driving piece and a third driving piece. According to the controlling and adjusting device disclosed by the invention, through adjustment of a distance between two first stop blocks and a distance between two stop blocks, the first moving rod is driven by the second driving piece to be longitudinally moved, and a longitudinal movement range of the printing spray head mounting base is adjusted, so that the longitudinal printing range of the printing spray head can be controlled; the second moving rod and the third moving rod are driven through the third driving piece soas to adjust a distance between the second moving rod and the third moving rod and the first moving rod is driven through the first driving piece to be horizontally moved, and thus, the horizontal movement range of the printing spray head mounting base is controlled, and the horizontal printing range of the printing spray head is further controlled, and therefore, control and adjustment of the printing range of the printer can be realized, and the working efficiency is improved.
