Abstract
This paper introduces a kind of 10-channel temperature controller-recorder for semiconductor air-conditioners of storage-transport containers. The core-controlled unit is the MCU-AT89C5 . DS1820 digital thermometers are used for temperature sampling and circuit checks. A micro-stylus printer prints values of the each point temperature and the working state timing. The output signal of the MCU through a photo-coupler drives two relays to control the working mode (cooling/heating) and the function state. The controlled program of the MCU is adopted C51 senior language and assembles language. 1-Wire/sup TM/ digital thermometers that predigest the external device and cable of the sensors greatly reduce cost and improve reliability.
