SZW-1A型数字式温度计(V2004)通讯故障诊断及排除

COMMUNICATION FAILURE DIAGNOSIS AND RECOVERY OF SZW-1A DIGITAL THERMOMETER(V2004)

基于SZW-1A型数字式温度计(V2004)的维护管理经验和仪器组成,对SZW-1A型数字式温度计(V2004)的通讯故障原因进行了研究。结果表明,导致SZW-1A型数字式温度计(V2004)通讯故障的主要原因有网络链路故障、网络通讯接口故障和仪器主机故障3大类。针对SZW-1A型数字式温度计(V2004)常见非网络链路通讯故障的判定提出了一套诊断流程,并提出了该型号数字式温度计常见通讯故障的排除方法。这些故障的排除方法,对和SZW-1A型数字式温度计(V2004)有类似硬件组成的SWY-1A型水位仪、SWY-II型水位仪、SWDW-1型水位地温综合观测仪等"十五"流体观测仪器的维护,有一定参考意义。

Based on the maintenance and management experience and its composition, the authors studied the communication failure reasons of SZW-1A digital thermometer （V2004）. The results showed that the main reasons led to communication failure in SZW-1A digital thermometer （V2004） are network link failure, network communication interface failure and thermometer itself failure. Then the authors put forward a set of failure diagnosis flow for the judgments of SZW-1A digital ther- mometer （V2004） common non-network link communication failure, and gave the methods to elimi- nate the common communication failure. For the maintenance and management persons of SZW-1A digital thermometer （V2004） and ＂the tenth five-year＂ fluid observation equipment, such as SWY- 1A water level instrument, SWY-II water level instrument, SWDW-1 water level and ground temper- ature comprehensive instrument, the article has a certain reference.
