| 摘要: |
| 为了建立远程分布式测量系统,提出了一个新颖高效的传输方法。利用双音多频数据编码和自行定义的传输协议使数据传输与语音传输相结合,创建了语音指导查询、超限自动报警的电话自动数据传输方法。通过对系统的设计、分析和样机试验,对这种方法进行了深入研究。试验应用证明这种传输方法结构简单、保密性强、实时性和可靠性很高,可以扩展到其他远程测量、控制系统中,具有重要实际应用价值和推广价值。 |

| Abstract: |
| A novel effective transmission method is proposed for establishing a distributed measurement system over long distance.The data transmission and voice transmission are integrated using Dual-Tone Multi-Frequency(DTMF) coding and a user defined transmission protocol.All information is automatically transmitted via telephone lines.Some functions such as searching with human voice guidance,automatic alarming when to exceed limitations are provided.This method is investigated deeplg by designing,analyzing and testing the system.This method is characterized of the sample structure,high security,high response speed and reliability.It can be expanded in other measure and control systems over long distance and is expected to find wide application. |
