Abstract
A draft detection system comprises a pressure transmitter, a collector, a computer and a power supply. The draft detection system also comprises a vent pipe for draft sensors installed on a ship. The pressure transmitter is installed on the vent pipes of draft sensors and connected to the collector through a water-tight junction box installed on the place where the vent pipe is installed. Liquid pressure parameters are automatically and continuously measured through the pressure transmitter in real time, so that the pressure parameters can be converted into current signal and output the current signal. Data are transmitted to the collector and the computer installed in a cab. After conversion and calculation, a user can obtain the real-time draft of a ship. Draft measurement of a ship can be carried out by a plurality of pressure transmitters at different position, and more accurate measurement can be obtained.
