【摘要】：在工业生产和人们日常生活中,计量工作的重要性越来越明显。计量是关乎农业生产、科学研究、国防建设、资源控制、环境保护、公共安全、国内外贸易和人们的生活、身体健康、生存质量的基重要支撑性工作,要求计量管理过程规范,计量检测过程精细。对计量工作而言,实用的检测设备则格外重要,在计量工作中的热工计量部分,所负责的工作是温湿度、压力和流量等量值的准确传递,而在温湿度校准工作中重要的一个计量器具则是温湿度巡检仪,本文就是以上述的热工计量为项目背景,进行相关调研并完成实用型温湿度巡检仪的设计与实现。本设计以环境试验设备的温湿度校准工作为研究对象,针对其校准设备存在价格昂贵、维护不便等问题。旨在研制一台有自主知识产权,并适合环境试验设备校准的实用型温湿度巡检仪。设计中温度测量部分的使用了PT100铂热电阻,这里避免了较为复杂的传统电桥测温法,取而代之是电位差计的方式,实现PT100铂电阻的温度测量。设备要求达到温度测量±0.3。C与湿度测量±3%RH的基本误差。实现温湿度数据的实时采集、存储与传输,较为简单的显示界面和并不繁杂的基本操作。同时,设计中湿度测量部分采用无线的方式,可在保证精度与有效距离范围内实时传输湿度数据,一定程度上降低了工作人员的工作强度,并能提高其工作效率。实用型温湿度巡检仪的整个系统采用模块化的设计,便于携带、可扩充性良好、便于调试和设备维护与更新、具有较高的性价比。设备经过严格的现场试验,基本达到了预期的设计目标,可以完成环境试验设备温湿度场的校准工作,能够较好的满足企业对环境试验设备的校准需求及其相关行业规范要求。
[Abstract]:In industrial production and people's daily life, the importance of measurement work is becoming more and more obvious. Measurement is an important supporting work related to agricultural production, scientific research, national defense construction, resource control, environmental protection, public safety, domestic and foreign trade and people's life, health and quality of life. The metrological process is fine. For metering work, practical testing equipment is especially important. In the thermal measurement part of metering work, the work is responsible for the accurate transmission of temperature, humidity, pressure and flow rate, etc. In the work of temperature and humidity calibration, an important measuring instrument is the temperature and humidity inspection instrument. In this paper, based on the above mentioned thermal measurement as the project background, the relevant investigation is carried out and the practical temperature and humidity inspection instrument is designed and implemented. This design takes the temperature and humidity calibration of the environmental test equipment as the research object, aiming at the problems of expensive price and inconvenient maintenance of the calibration equipment. The purpose of this paper is to develop a practical temperature and humidity inspection instrument which has independent intellectual property rights and is suitable for calibration of environmental test equipment. In the part of temperature measurement, PT100 platinum thermal resistance is used. Instead of the traditional bridge temperature measurement method, the temperature measurement of PT100 platinum resistance is realized by potentiometer instead. The basic errors of temperature measurement 卤0.3.C and humidity measurement 卤3%RH are achieved. The real-time acquisition, storage and transmission of temperature and humidity data, simple display interface and uncomplicated basic operation are realized. At the same time, the humidity measurement in the design adopts wireless mode, which can transmit humidity data in real time in the range of precision and effective distance, which can reduce the working intensity and improve the working efficiency to a certain extent. The whole system of practical temperature and humidity inspection instrument adopts modularized design, which is easy to carry, good expandability, easy to debug and equipment maintenance and update, and has high performance and price ratio. After strict field test, the equipment can basically achieve the expected design goal, can complete the calibration of temperature and humidity field of environmental test equipment, and can better meet the calibration requirements of environmental test equipment and related industry standards.
