Buoy modularization collection system based on CAN bus

Abstract

The present invention discloses a buoy modularization collection system based on a CAN bus. The collection system is connected in parallel with the loop of a CAN bus, the loop of the CAN bus is connected in series with a terminal resistor, the collection system comprises a collection control mainboard module and a collection control slave board module being connected in parallel with the CAN bus, the collection control slave board module is provided with output signal collection circuits of a plurality of sensors for data collection, and a plurality of signals are transmitted to the collection control mainboard module in the CAN bus through the CAN communication interface itself through the sensing data obtained through a slave collection terminal. The system performs data collection through adoption of the embedded technology, the analog quantity technology, the digit communication technology and the CAN bus technology, the CAN bus is employed to realize function division data collection processing of the collection control mainboard module and the collection control slave board module, and the system provided by the invention is in a distribution mode, is capable of intelligent extension, high in maintenance, high in timeliness, low in power consumption and high in reliability.

Description

technical field [0001] The invention belongs to the field of marine engineering monitoring, and in particular relates to a CAN bus-based buoy modular acquisition system. Background technique [0002] Ocean buoy is an unattended, highly automated, advanced ocean hydrometeorological telemetry equipment, which can monitor ocean hydrometeorological parameters continuously, fixed-point, and automatically for a long time, and provide real-time data for disaster marine environment forecast, ocean development, and ocean engineering. , is the main source and important component of data in the marine disaster early warning and forecasting system. With the diversity of marine observation data and the increasing number and types of sensors carried, if the system is concentrated on one acquisition board, the system will be too bloated. Contents of the invention [0003] The object of the present invention is to provide a buoy modular acquisition system based on CAN bus, which has the ...
