- 摘要:
- 随着地面气象观测自动化程度的提高,DZZ3型自动气象站得到了全面的推广及应用,有效地解决了原有自动气象站系统观测设备、观测技术落后和无法扩展新要素的问题,提高了地面气象观测的集约性、准确性和可靠性,较好地满足了现有气象业务发展的需要。针对五河自动气象站运行过程中出现地温数据异常的情况,按照地温传感器常规故障的处理流程和方法,无法准确分析、判断地温数据异常发生的故障单元。为了尽可能减小地温传感器故障对气象观测数据产生的影响,同时结合电力电子相关理论知识,经过分析验证,确定五河自动气象站地温数据异常的原因是主采集器与地温分采集器接地点之间存在电位差,形成了地环路干扰,使主采集器与地温分采集器之间的信号传输线在采集、传送有用信号的同时,也为这种干扰源搭建了一个闭合回路,从而形成地环路电流,造成自动气象站地温数据的异常。针对这一问题,通过对主采集器与地温分采集器之间的接地进行S型等电位连接,实现主采集器与地温分采集器的接地点都通过一点入地,并与大地相连接,消除各点间存在的电位差,保障了五河自动气象站地温数据的准确性、连续性,也为今后DZZ3型自动气象站的维修维护提供参考。
- Abstract:
- With the improvement of the degree of automation of ground meteorological observation, DZZ3 automatic weather station has been a comprehensive promotion and application, which effectively solved the original automatic weather station system observation equipment, observation technology behind and can not expand the new elements of the problem t improves the ground meteorological observation of the intensive, accura and reliability, it is better to meet the needs of the development of existing meteorological services. According to the earth temperature data abnormal situation five automatic weather station operation process, according to the process and method of processing the temperature sensor of the conventional fault, unable to accurately analyze and judge the fault of abnormal geothermal data unit. In order to minimize the arth temperature sensor fault of meteorological observation data, combined with the power electronics related theoretical knowledge at the same time, through the analysis, determine the cause of Wuhe automatic weather station earth temperature data anomaly is divided between the main collector and collector grounding in geothermal potential difference he formation of the earth loop interference, signal transmission line makes the main collector with the earth temperature between the sub collector in the useful signal collection and transmission at the same time also set up a closed loop for the source of this interference, thus forming the loop current, caused by the abnormal geothermal data of automatic weather station. To solve this problem, based on the main points between the collector and the temperature collector grounding type S equipotential connection, grounding main collector and collector are divided by a ground point into the ground onnected with the earth, eliminate the point between the potential difference and guarantee the accuracy of the automatic weather station system the temperature and the continuity of the dataalso provide a reference for the maintenance of DZZ3 automatic weather station in the future.
