Embodiment Construction

[0050] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0051] Such as figure 1 Shown, a kind of drift observer test evaluation method of the embodiment of the present invention, described drift observer test evaluation method comprises:

[0052] Step 101: the drifting observer is released in the sea area, the anchorage buoy is set in the sea area near the drifting observer, and the on-board automatic weather station, GPS locator and sea temperature and salinity measuring instrument are set on the test ship in the sea area near the drifting observer;

[0053] Step 102: obtain the hardware failure information of the drifting observer, calculate the mean time between failures of the drifting observer according to the hardware failure information, obtain the drifting observer hardware reliability parameter;

[...

Abstract

The invention provides a test evaluation method of a drift observation instrument. The method comprises the steps of acquiring hardware fault information of the drift observation instrument to obtain a hardware reliability parameter of the drift observation instrument; acquiring software fault information of the drift observation instrument, and combining the software fault information with software repair information to obtain a software reliability parameter of the drift observation instrument; acquiring and calculating the missing measurement rate of the drift observation instrument, and calculating according to the missing measurement rate to obtain a data integrity parameter of the drift observation instrument; acquiring the measurement data of the drift observation instrument as well as comparison data measured by a shipborne automatic weather station, a global positioning system (GPS) locator and a sea temperature salinity measuring instrument, and carrying out comparative analysis on the measurement data and the comparison data so as to determine a measurement data accuracy parameter of the drift observation instrument; calculating the weighted sum of the hardware reliability parameter, the software reliability parameter, the data integrity parameter and the measurement data accuracy parameter to obtain a test evaluation result of the drift observation instrument.

Description

technical field [0001] The invention relates to the technical field of marine observation equipment manufacturing, in particular to a method for testing and evaluating a drifting observation instrument. Background technique [0002] In recent years, the drifting observation instrument is a drifting buoy device that can simultaneously observe meteorological elements such as air temperature, air pressure, and wind, as well as important marine parameters such as sea temperature and sea salt. Compared with anchored buoys, the monitoring cost is low and the benefit is high. It can be used as a This kind of consumable buoy has been used in marine meteorological observation for a long time. Existing drift observation instruments often have faults or inaccurate measurement data during use, which seriously affects the use and observation of the equipment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for testi...
