Whole ship monitoring and warning system based on double Ethernet and ring network

Abstract

The invention provides a whole ship monitoring and warning system based on double Ethernet and a ring network. The system comprises a power supply layer, a signal acquisition layer, a network communication layer and a display operation layer, wherein the power supply layer comprises at least one uninterrupted power supply (UPS); the signal acquisition layer comprises at least one programmable logic controller (PLC) processing unit; the network communication layer comprises at least three interconnected switches; the display operation layer comprises at least one touch screen or computer; and the power supply layer supplies power to the PLC processing unit, the switches and the touch screen or computer. The system comprises the following operation processes that: the PLC processing unit acquires and processes a signal to acquire processing data; whether the current transmission channel of the system is normal or not is detected; and the touch screen or computer displays the processing data when the transmission channel is normal. The system has high communication speed, large communication data volume, rich display contents and a clear and reliable interface, and is stable.

Description

technical field [0001] The invention relates to an alarm system, in particular to a marine alarm system based on double Ethernet and ring network. Background technique [0002] Existing marine alarm systems are usually transplanted from land alarm systems, which do not fully consider the particularity of the ship's operating environment, resulting in constant problems in various aspects. Existing marine alarm systems usually use a single-chip microcomputer as a signal acquisition module, the communication method uses MODBUS or PROBUS communication, and the display module often uses indicator lights or LCD display. However, due to the use of single-chip integrated circuits, usually, there are many electronic components required, so when one of the electronic components is damaged, the entire circuit board needs to be replaced, thus making the system less stable and costly; and these integrated The circuit is not a standard product, and it is difficult to find a replacement p...

Problems solved by technology

However, due to the use of single-chip integrated circuits, usually, there are many electronic components required, so when one of the electronic components is damaged, the entire circuit board needs to be replaced, thus making the system less stable and costly; and these integrated The circuit is not a standard product, and it is difficult to find a replacement product when it is damaged, which greatly hinders the normal use of the ship; in addition, due to the use of MODBUS or PROBUS communication methods, the communication performance of these two communication methods is poor and the communication speed is slow. The amount of data is small; and through the indicator light or LCD display, the amount of information that can be displayed is small, the display interface is not clear, and the display is inconvenient
