Intelligent refrigerated container power supply switching device and control method thereof

Abstract

An intelligent refrigerated container power supply switching device comprises an intelligent refrigerated container power supply management device generating a control instruction. The intelligent refrigerated container power supply management device is connected with a data communication module. The data communication module is connected with a switching logic generating module. The output ends of an alternating-current measurement module and a direct-current measurement module are connected with the input end of the switching logic generating module. The output end of the switching logic generating module is connected with the input end of a switching execution module. The output end of the switching execution module is connected with the input ends of an AC/DC power supply conversion module, an inverter module, a storage battery direct-current power supply line, and an alternating-current power supply line. The AC/DC power supply conversion module, the inverter module, the storage battery direct-current power supply line and the alternating-current power supply line supply power to a refrigerated container refrigeration unit. A control method of the intelligent refrigerated container power supply switching device has the advantage of meeting the needs of different specifications, different power and different power utilization types of refrigerated container groupage traffic, and can be applied and popularized to the field of refrigerated container power supply.

Description

technical field [0001] The technology of the invention relates to the field of power supply for refrigerated containers, in particular to an intelligent power supply switching device for land-transported refrigerated containers, and a control method for the application of the system. Background technique [0002] Due to its convenience and flexibility, mechanically refrigerated refrigerated containers for land transportation have increasingly become the main equipment for cold chain transportation. At present, the container body of the refrigerated container and the fuel-fired generator set are usually fixed on the corresponding installation position of the transport vehicle by means of fixed installation, and the two are connected by cables to realize one-to-one power supply for the refrigeration equipment of the refrigerated container. This refrigerated container structure and fixing method make it impossible for a set of power supply to supply power to multiple refrigerat...

AI Technical Summary

Problems solved by technology

This refrigerated container structure and fixing method make it impossible for a set of power supply to supply power to multiple refrigerated container refrigerating units of different specifications, different power, and different AC / DC power supply modes.

This results in the disadvantages of land transport refrigerated containers occupying vehicle resources, inflexible transshipment, inability to marshal transport, and poor operating economy; at the same time, it is also not conducive to the optimal utilization of fuel-fired generator sets and other forms of power supply such as battery packs and mains power.
