Multipoint temperature collection system and collection method thereof

Abstract

The invention discloses a multipoint temperature collection system and a collection method thereof. The system comprises a plurality of temperature sensors which are hung on the same bus, and a PIC single chip control system, an RS232 communication module and a PC computer main controller which are sequentially connected with each other, wherein the PIC single chip control system is also connected with a liquid crystal display device and a keyboard, and the PIC single chip control system is also hung on the bus. The method comprises the following steps: performing initialization; issuing a jump ROM order by a host; re-issuing a uniform temperature conversion startup code by the host, waiting for one second, and re-initializing; and sequentially matching correspondent temperature sensors, storing the collected temperature into a memory space, and displaying the collected temperature on the PC computer main controller. The system and the method realize the distribution-type control, can display the temperature of individual point on the computer interface, and can read the temperature one by one in a short time, so the time value is smaller than that of the traditional way, and the efficiency is improved.

Description

technical field [0001] The invention relates to a temperature collection system and a collection method thereof, in particular to a multi-point temperature collection system and a collection method thereof for a freezer. technical background [0002] Temperature detection is a relatively common method in the control system. At present, analog circuits or digital circuits are generally used to realize most of the temperature acquisition and control functions, and the control performance is not high. [0003] The significance of single-chip microcomputer application is not limited to its wide range and economic benefits, but more importantly, it has fundamentally changed the traditional control system design ideas and design methods, but for the temperature collection and detection of freezers, currently It has not been realized by using a single-chip microcomputer. The applicant of the present invention is committed to researching a multi-point temperature acquisition system ...
