Based on SCM multi-functional temperature testing system

design

1、Preface

With the development of society and the technological progress, people pay more and

more attention to the importance of temperature detection and display. Temperature

detection and status display technology and equipment has been widely applied in

industries, products on the market emerge in endlessly. Temperature testing and also

gradually adopt the automatic control technology to realize the monitor. This topic is

a temperature testing and status of the monitoring system.

2、System solutions

This system USES the monolithic integrated circuit AT89C51 as this system. The

whole system, the hardware circuit including power supply circuit, sensor, the

temperature display circuit circuit, upper alarm circuit . The alarming circuit can be

measured in upper temperature range, screaming voice alarm. The basic principle for

the temperature control DSl8B20: when the temperature signal acquisition to after

temperature signal sent to handle, AT89C51 temperature to LCD screen, SCM

according to initialize the upper temperature setting, namely, if the judgement of

temperature than the highest temperature cooling fan is started, If the temperature is

less than the lowest temperature setting on alarm device.

3、The system hardware design

（1）AT89C51 SCM are introduced

The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer

with 4K bytes of Flash programmable and erasable read only memory (PEROM) and

128 bytes of data random-access memory(RAM). The device is manufactured using

ATMEL Co.’s high-density nonvolatile memory technology and is compatible with

the industry-standard MCS-51 instruction set and pin-out. The on-chip Flash allows

the program memory to be reprogrammed in-system or by a conventional nonvolatile

memory programmer. By combining a versatile 8-bit CPU with Flash on a monolithic
