本文涉及基于HART协议的压力仪表技术,尤其涉及基于GSM的无线压力仪表领域。传统的压力仪表一般采用电缆式连接,在电源和信号端均需有线式连接方式,尤其当仪表安装位置特殊时,对电缆的布局要求更高。本文提出基于GSM无线技术压力仪表技术,是在符合HART智能仪表基础上,对仪表智能读数的又一技术改进,即利用成熟的GSM空对空传输方式解决了其他无线技术局限于采集距离的缺陷,对智能压力仪表的无线数据采集起到了技术革新的技术。
This document relates to pressure gauge technology based on the HART protocol, and more particularly to the field of wireless pressure gauges based on GSM. Conventional pressure gauges generally use a cable connection, which requires a wired connection between the power supply and the signal terminals. In particular, when the installation location of the instrument is special, the layout of the cable needs to be higher. In this paper, based on the GSM wireless technology pressure gauge technology, is based on the HART smart meter based on the smart meter reading another technical improvement, that is, the use of mature GSM air-to-air transmission to solve the other wireless technology is limited to the collection of defects , On the intelligent pressure instrument wireless data acquisition has played a technological innovation.
