摘要
研制了一种超低功耗、电池供电的温度数据采集分时记录仪,用一节1号电池大小的锂电池(12Ah)可连续工作5a。特别适用于现场无电源的温度数据采集及分时记录。由多台采集仪和一台PC机可构成离线式温度数据采集分时记录系统。可广泛应用于供热、空调、建筑节能测试、环境温度监测等系统。介绍仪表的软硬件设计的主要特点及上位机通讯软件的设计。
A temperature data acquisition and time -sharing recording instrument with an ultra -low power consumption can work continuously for five years with a C-size battery in a place without power supply.Several instruments of this kind and one PC can be used to form an off-line temperature data acquisition and sharing-record system,such a system can be used for heating,air-conditioning,saving energy test of building,measurement of environmental temperature,and so on.The main design features of software and hardware of the instrument and the design of communication program in the computer are discussed in detail.
