Introduction

JJF1002-2010 "Rules for the preparation of national metrological verification procedures", JJF1001 "General measurement terms and definitions" And JJF1059.1 "Measurement Uncertainty Assessment and Representation" together constitute the basic series of norms developed by this Code. This order is the first release. Inspection procedures for marine dumping recorders

1 Scope

This procedure applies to the first verification of the marine dump recorder (hereinafter referred to as "dumping instrument"), subsequent verification and In the inspection, only for the dumping instrument and run the track-related positioning measurement, and the depth of the relevant pressure measurement.

2 reference file

This procedure refers to the following documents. JJF1118-2004 Global Positioning System (GPS) Receiver (geodesic and navigation) calibration specification Global positioning system (GPS) measurement specification GB/T Any reference to the date of the document, only the date of the version of the application of this procedure; those who do not note the date of the reference file, The latest version (including all amendments) applies to this procedure.

3 Overview

Dumping instrument is a real-time collection, transmission and storage dumping ship running track, draft depth, dumping time, depending on Frequency signal, mud door open state and other data, the dumping activities for real-time dynamic visual monitoring equipment. Dumping instrument positioning measurement and pressure measurement part by the pressure sensor, GPS receiver (or Beidou receiver), the number According to the collection of host and pressure values and positioning value display part of the composition. Its working principle shown in Figure 1. Dumping the ship to eat deep Through the pressure sensor measurement, output and depth corresponding to the pressure signal, by the data acquisition host processing, the output pressure Force sensor installation position to the ship's water line pressure value; dumped ship running track by GPS receiver (or the Big Dipper Receiver) positioning antenna to obtain GPS (or Beidou) signal, processed by the data acquisition host, the output ship set Bit value. Figure 1 dumping instrument working principle block diagram The GPS measurement data of this procedure uses WGS-84 coordinates, and the Beidou measurement data uses CGCS2000 coordinates.

4 Measurement performance requirements

The measurement performance of the dump instrument should meet the requirements of Table 1. ......
