船舶货舱温度遥测系统的设计

近年来,我国远洋和船舶轮机自动化的水平有了较快的提高,但货舱温度监控却始终是一个薄弱环节,本文设计及制作了一个基于DS18B20的温度实时无线遥测报告系统,该系统采用单工单收单发模式,由于采用了DF无线数据传输方式和通过串口与PC通信,可方便容易地检测并记录远处0至＋100℃范围（范围可变）的温度。

Design of the Temperature telemetry system about the Ships cargo hold

In recent years, our country open sea and the coastal ships turbine automation"s level had the quick enhancement, but the temperature monitoring about the ships cargo hold is a weak link all the time.We design and produce a temperature real-time wireless telemetry report system and it adopts simplex mode.Because it using wireless data transmission of DF and communicate with the PC through serial interface,so it can detects and records the distant temperature from 0 to 100°c range (range variable) easily.Each measurement point may measure many environment variables,which are reflected in the communication protocol.
