统一水文监测数据传输规约探讨

How to Unify Protocols for Hydrological Monitoring Data Transmission

近年水文自动测报系统飞速发展,市场规模扩大,厂家与产品也越来越多。由于数据传输规约不统一,造成不同厂家所建系统难以兼容,遥测终端不能互换,给系统建设及运行管理带来不便。基于此,行业主管部门组织编制了一套规约,以期全国统一。本文阐述了规约编制遵循的原则,采取的相关技术措施,说明了规约的框架结构,并列举实例,详细介绍了ASCII和HEX/BCD两种字符编码的实现方法。从现实角度出发,展望了统一规约所需经历的过程,提出了应采取的相关措施。

With rapid development of hydrological telemetry system in recent years,its market has been expanded with more and more concemed manufacturers and products.For the lack of unified data transmission protocols,different systems provided by different manufacturers are not compatible,telemetry terminals are not interchangeable,so that the system construction and operation management is very inconvenient.Based on this situation,a new unified specification was established by the organization of competent authority.This paper expounded the principle and related technical measures in compiling process.It also explained the frame structure of the statute.Meanwhile,approaches of two character code,ASCⅡ and HEX/BCD,were illustrated by instants.Under the current condition,it proposed how to boost unified specification,and put forward the relevant measures.
