Background
The storage logistics field often need store article that need low temperature refrigeration such as bacterin in the warehouse, just need the temperature in the warehouse to keep invariable low temperature, thereby must guarantee the normal operating that refrigerating system can be stable for a long time, traditional refrigerating system all is provided with standby equipment generally, but its standby equipment only breaks down or the manual start-up when overhauing at normal operating's equipment, this has just led to the fact certain down time, not only influence the temperature in the warehouse, and the great difference of operating duration between the equipment, cause partial equipment fatigue operation easily, partial equipment standby time overlength, thereby influence the life of equipment.
Disclosure of Invention
The invention aims to solve the technical problem of providing an automatic switching system of vaccine storage refrigeration equipment, which is stable and reliable in operation, can automatically realize the timing switching among equipment and ensure the constant temperature in a warehouse.
The invention is realized by the following technical scheme:
the automatic switching system for the vaccine storage refrigeration equipment comprises a power supply, a CPU (central processing unit), three refrigeration pumps, three cooling towers and a generator, wherein the three refrigeration pumps are connected in parallel, the three cooling towers are connected in parallel, the power generator is connected with the power supply in parallel to supply power to the system, a control end of the CPU is respectively connected with the three refrigeration pumps and the three cooling towers through relays, the CPU controls the three refrigeration pumps and the three cooling towers to be switched at regular time according to the interval time set by the timer, the two refrigeration pumps and the three cooling towers are guaranteed to be switched on and off, the running time and the shutdown time of each equipment are the same, and when the power supply is abnormal and the power supply is stopped, the CPU automatically controls the generator to be started to supply power to the system.
Further, an automatic switching system of vaccine storage refrigeration equipment, it still includes control button and display screen with CPU is connected.
Furthermore, a temperature sensor is arranged in the warehouse, the output end of the temperature sensor is connected with the input end of the CPU through a cable, and the CPU receives information of the temperature sensor to control the rotating speed of the refrigeration pump.
The invention has the advantages of
According to the automatic switching system for the vaccine storage refrigeration equipment, the CPU controls the three refrigeration pumps and the three cooling towers to be switched at regular time according to the interval time set by the timer, so that the two refrigeration pumps are switched on and the one refrigeration pumps are switched on, the running time and the shutdown time of each equipment are the same, and when the power supply is abnormal and the power supply stops supplying power, the CPU automatically controls the generator to start to supply power to the system. The system runs stably and reliably, the equipment cannot stop running due to power failure, timing switching between the equipment is automatically realized, the relay is arranged, the time delay function is realized, even in the switching process, the two equipment can be always kept running simultaneously, the temperature in the warehouse is ensured to be constant, the running time and the standby rest among the equipment are balanced, and the service life of the equipment is prolonged.

Detailed Description
The automatic switching system for the vaccine storage refrigeration equipment comprises a power supply, a CPU (central processing unit), three refrigeration pumps connected in parallel, three cooling towers connected in parallel and a generator, wherein a timer is arranged in the CPU, the generator and the power supply are connected in parallel to supply power to the system, a control end of the CPU is respectively connected with the three refrigeration pumps and the three cooling towers through relays, the relays have a time delay function and ensure that two equipment still run in the switching process, the CPU controls the three refrigeration pumps and the three cooling towers to be switched at regular time according to the interval time set by the timer so as to ensure that two equipment are switched on and one equipment are switched on, and the running time and the shutdown time of each equipment are the same, so that the equipment runs uniformly. When the power supply is abnormal and the power supply source stops supplying power, the CPU automatically controls the generator to start to supply power to the system, and the stable operation of the system is ensured.
Further, the automatic switching system for the vaccine storage refrigeration equipment further comprises a control button and a display screen which are connected with the CPU, manual control can be carried out through the operation button, and the running condition and time of the equipment can be displayed on the display screen in real time.
Furthermore, a temperature sensor is arranged in the warehouse, the output end of the temperature sensor is connected with the input end of the CPU through a cable, the CPU receives information of the temperature sensor to control the rotating speed of the refrigerating pump, and when the temperature in the warehouse is lower than or higher than a set temperature range, the CPU controls the rotating speed of the refrigerating pump, so that the temperature in the warehouse is adjusted.
According to the automatic switching system for the vaccine storage refrigeration equipment, the circulating cooling water is cooled by the cooling tower, and then is pumped into the refrigeration pipeline and the refrigeration equipment in the warehouse through the refrigeration pump to cool the temperature in the warehouse, the circulating water after heat exchange returns to the cooling tower to be cooled, and then the process is repeated, the CPU controls the three refrigeration pumps and the three cooling towers to be switched at regular time according to the interval time set by the timer, so that the two-in-one switching is ensured, the running time and the shutdown time of each equipment are the same, and when the power supply is abnormal and the power supply stops supplying power, the CPU automatically controls the generator to start to supply power to the system. The system runs stably and reliably, the equipment cannot stop running due to power failure, timing switching between the equipment is automatically realized, the relay is arranged, the time delay function is realized, even in the switching process, the two equipment can be always kept running simultaneously, the temperature in the warehouse is ensured to be constant, the running time and the standby rest among the equipment are balanced, and the service life of the equipment is prolonged.
In conclusion, the automatic switching system for the vaccine storage refrigeration equipment, which is protected by the application, is stable and reliable in operation, and can automatically realize the timing switching between the equipment, so that the temperature in the warehouse is constant.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
