本文从传感器检定时如何保证准确地测量其输出信号的角度出发,分析了过去几年我国检定MAREX浮标传感器工作中在测量方面存在的问题,介绍了为解决这些问题而研制的“HJF1-1型浮标传感器检定用测量装置”的工作原理、基本组成和设计思想,并列举了两个实例比较不同测量、计算方法对检定结果的影响,从而提出了在海洋环境自动监测系统的传感器检定工作中一个值得注意的普遍性问题。 This paper analyzes how to measure the output signal of the MAREX buoy sensor in our country in the past years from the angle of how to ensure the accurate measurement of the output signal of the sensor. In this paper, the problems existing in the measurement of the MAREX buoy sensor in our country have been analyzed. The “HJF1-1 Buoy sensor testing with the measuring device, ”the working principle, the basic composition and design ideas, and lists two examples to compare different measurements, the impact of calculation methods on the test results, and thus proposed in the marine environment monitoring system for automatic sensor testing a Worth noting the universality of the problem.
