Automatic switching system of vaccine warehousing refrigerating equipment

Abstract

The invention relates to the technical field of warehouse logistics, in particular to an automatic switching system of vaccine warehousing refrigerating equipment. The automatic switching system comprises a power supply, a CPU, three refrigerating pumps connected in parallel, three cooling tower connected in parallel, and an electric generator, wherein a timer is embedded in the CPU; the electricgenerator and the power supply are connected in parallel to power the system; the control end of the CPU is connected with the three refrigerating pumps and the three cooling towers through relays; and the CPU controls timed switching among the three refrigerating pumps and three cooling towers according to the time interval set by the timer, so that the situation that two units are started and one unit is standby is ensured, the running time and the halt time of each unit are the same, and the units are operated in balance. When power supply is abnormal, the power supply stops supplying power, the CPU automatically controls the electric generator to be started for supplying power to the system, and the system is ensured to run stably. The automatic switching system is stable and reliablein operation, automatically realizes timed switching of equipment and ensures that the temperature in a warehouse is constant.

Description

technical field [0001] The invention relates to the technical field of warehousing and logistics, in particular to an automatic switching system for vaccine storage refrigeration equipment. Background technique [0002] Warehouses in the field of warehousing and logistics often need to store vaccines and other items that require low-temperature refrigeration, so the temperature in the warehouse needs to be kept at a constant low temperature, so it is necessary to ensure that the refrigeration system can operate stably for a long time. Traditional refrigeration systems are generally equipped with backup equipment. , but its backup equipment is only manually started when the equipment in normal operation fails or is overhauled, which causes a certain amount of downtime, which not only affects the temperature in the warehouse, but also has a large difference in operating time between equipment, which is easy to cause Some equipment is running fatigued, and some equipment has a ...
