Express delivery vehicle provided with multifunctional freshness retaining device

Abstract

The invention discloses an express car with a multifunctional fresh-keeping device, which includes a single-chip microcomputer, a synchronous phase-shifting module, an A / D conversion module, an alarm module and a thermocouple module, and the single-chip microcomputer is respectively connected to a display module, a keyboard module, an alarm module and a printer module , an interface module, an A / D conversion module and a synchronous phase-shift module, and the synchronous phase-shift module is also connected to the A / D conversion module through a refrigerator, a thermocouple module, a transmitter module and a compensation conversion amplification module in turn. The present invention takes a single-chip microcomputer as the main body to form an intelligent controller capable of processing complex data and control functions, so that it can be used as an independent single-chip microcomputer control system, and can cooperate with a microcomputer to form a two-level control system. The temperature can be precisely adjusted, so that the whole system has high control precision, high flexibility and reliability.

Description

technical field [0001] The invention relates to an express vehicle, in particular to an express vehicle with a multifunctional fresh-keeping device. Background technique [0002] The use of express vehicles for commodity transportation is a crucial link in the e-commerce industry.
