The Designing Of The Wireless Mutiple Temperature Collecting System

With the rapid development of computer technology,data collecting and moniter systems are applied in industry manufacture.Being a new field of wireless industry, short distance wireless transmission is widely used in many fields,such as safty production,home appliance,data collection.In some special situations,wireless data transmission is the only way,which provides a new applying field in short distance wireless data collecting and moniter system.According to the limitations of the wire temperature collection,this article designs a new multiple wireless temperature collecting system,and makes detailed designing ideas and general frame of muti-temperature collection and transmission system,and elaborates the hardwre and software of the instrument.The entire system is composed of two parts:one is temperature data collecting and sending terminal consisted of DS18B20 net,LCD 1602,nRF905,and STC mcu.The other is the terminal of temperature data receive and application program in PC which is consisted of STC mcu,nRF905,MAX232.In software design,time synchronization and dormancy system is used to reduce the power consumption and extend working hours,and the upper program is designed by LabVIEW,which the data results are displayed friendly,and operated easily.In the end,we make an entire test and analysis,and make appropriate designs of anti-jamming of the system.
