Description

Automatic three-dimensional refrigeration house temperature field adjusting equipment and control method thereof Technical Field The invention relates to the technical field of cold chain logistics storage, in particular to automatic three-dimensional refrigeration house temperature field adjusting equipment and a control method thereof. Background The automatic three-dimensional refrigeration house is a storage facility in a modern cold chain logistics system, and realizes high-density storage and automatic access of cargoes through a high-rise goods shelf, a tunnel stacker, an automatic control system and the like. In a low-temperature storage environment, maintaining uniformity and stability of a temperature field of a space in the storage is one of main factors for guaranteeing quality and safety of stored articles. At present, the temperature control of an automatic three-dimensional refrigeration house mainly depends on a fixed refrigeration air supply system. Generally, cold air generated by a refrigerating unit is delivered into a warehouse through an air duct and an air supply outlet which are positioned at the upper part or a specific position of the warehouse, and is mainly diffused by means of density difference and limited convection of the air, so that the cold energy is distributed to the whole storage space. The stacker is used in this system only as a handling device for performing the goods access operation. However, due to the barrier effect of the densely arranged shelves and the goods themselves, it is difficult for the cold air flow relying on natural convection and limited diffusion to effectively penetrate deep layers of the shelves to reach the bottom of the roadway and the corner areas in the warehouse. This results in different cargo areas, especially areas far from the air supply opening, where the temperature is significantly higher than the set value, forming temperature dead corners or local hot spots, seriously affecting the storage safety of temperature fluctuation sensitive articles. The existing system belongs to a static and passive temperature regulation mode. The air supply position, air quantity and direction are usually fixed or preset, and cannot be actively adjusted according to the real-time and dynamic temperature distribution change in the warehouse. For example, when the warehouse door is opened due to goods storage and taking operation or local goods generate heat, the system cannot perform rapid and accurate compensatory air supply on the disturbed hot zone in a targeted manner, and the system can only cope with the situation by wholly reducing the temperature set value or prolonging the refrigerating time, so that the efficiency is low. In addition, to ensure that the above-mentioned temperature dead angle also meets the storage requirement, the refrigeration system often needs to be operated with high intensity for a long time to maintain the overall lower average temperature, which causes excessive refrigeration in other areas in the warehouse, resulting in a great amount of energy waste. Meanwhile, the stacker is used as the only equipment capable of moving in a large range in a three-dimensional space in a warehouse, the function of the stacker is limited to goods handling, the movement capability of the stacker is not used for improving the environment, and the comprehensive utilization efficiency of the equipment is low. Disclosure of Invention The invention provides automatic three-dimensional refrigeration house temperature field adjusting equipment and a control method thereof, which are used for solving the problems of uneven temperature field, low energy efficiency, large passive adjustment limitation, single equipment function and the like of the existing automatic three-dimensional refrigeration house adopting a refrigeration air supply system. The invention provides automatic three-dimensional refrigeration house temperature field adjusting equipment, which is applied to a stacker with a lifting function and a horizontal movement function, and comprises: The air guide pipe is arranged on the stacker and extends along the height direction of the stacker, a plurality of air return openings are formed in the air guide pipe at intervals along the height direction of the stacker, and an air outlet is formed in the top of the air guide pipe; The driving mechanism is communicated with the air guide pipe and used for driving air to enter from the air return opening and be guided out from the air outlet; the temperature detection mechanism is arranged in the refrigeration house and used for detecting temperature information of the refrigeration house; And the control system is electrically connected with the stacker, the driving mechanism and the temperature detection mechanism and is configured to determine a target area with abnormal temperature in the refrigerator according to the temperature information, control the stacker to move to the target area
