Control device used for ship

Abstract

The invention discloses a control device used for a ship. The device includes a power supply circuit, a first voltage output circuit, at least one second voltage output circuit, a processor, a safe start circuit, an automatic switch-off circuit and a fault monitoring circuit. The processor outputs a first preset electrical signal to the safe start circuit. The safe start circuit generates a start electrical signal according to the first preset electrical signal and outputs the start electrical signal to the second voltage output circuit so as to start the second voltage output circuit. The automatic switch-off circuit receives switch-off electrical signals from the processor and / or the fault monitoring circuit and switches off the first voltage output circuit and / or the second voltage output circuit according to the switch-off electrical signals. The control device used for the ship improves the security of a ship.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship control device. Background technique [0002] In marine systems, the microcomputer communication control center is generally directly connected to the switching power supply. Most switching power supplies on the market do not have automatic opening and closing functions or only have a general opening and closing function, but there are many defects in practical applications. For example, when a module in the marine system fails, the main processor must first control the working state of the fault indicator light, and then rely on people to turn off the corresponding output power according to the working state of the fault indicator light. Therefore, from the occurrence There will be a certain delay between the failure and the shutdown of the output power due to human factors, and this delay may even cause unexpected situations. In addition, when the existing marine system i...

[0002] In marine systems, the microcomputer communication control center is generally directly connected to the switching power supply. Most switching power supplies on the market do not have automatic opening and closing functions or only have a general opening and closing function, but there are many defects in practical applications.

For example, when a module in the marine system fails, the main processor must first control the working state of the fault indicator light, and then rely on people to turn off the corresponding output power according to the working state of the fault indicator light. Therefore, from the occurrence There will be a certain delay between the failure and the shutdown of the output power due to human factors, and this delay may even cause unexpected situations

In addition, when the existing marine system is powered on, the power supply will supply power to the main processor and other modules connected to peripherals (such as input boards and output boards). Initialization, so the main processor cannot control other modules yet, sometimes the system will output an error signal at the moment when the power is turned on, resulting in an unexpected situation
