It is included in the first terminal box 30 and the first terminal box 30 connected to the other end of the first wire 20 and extending to each terminal constituting the device 12 A second wire 40 connected to the outside by combining one or more terminals, and a second terminal box 50 or one or more sensors 60 / operator 70 connected to the other end of the second wire 40. Include.

In more detail, the central processing unit 11 and the input / output device 12 are connected through a network cable 13, and the input / output device 12 connected to one side of the network cable 13 is each electrically connected. And a plurality of terminals to which a bundle of wires for transmitting and receiving signals from the sensor 60 / operator 70 or the terminal box is connected. At this time, the first wire 20 extending from the terminals of the input and output device 12 is each of the transmission signal and the wire in order to transfer the signal with the sensor 60 / operating device 70 or the other terminal box for each wire One-to-one matching is achieved, which leads to serious waste of wires.

That is, in the case of applying the automatic vessel control system to the centralized input and output device 12 as in the conventional case, a large amount of wires are required, and in the shipyard, as shown in FIG. 1, the automation system 10 and various sensors 60. Terminal box is installed between the / operation device 70 to reduce the absolute length of the wire length, but as the connection part of the wire increases, the working time and the inspection time of the initial automatic vessel control system are increased. It causes a problem. In addition, the increase in the wire connection increases the likelihood of disconnection, short circuit, and the like, which may cause an error of the entire ship automatic control system.

The present invention devised to solve the above problems is to install the remote I / O device of the ship automation system in close proximity to the various sensors to reduce the wire length between the remote I / O device and the sensor / operating device, between the remote I / O device and the central processing unit By reducing the wire connection area of the cable, the amount of wire usage is significantly reduced, and it is impossible to transmit and receive a specific signal when an error occurs in the conventional I / O device, and it can occur at the terminals of the I / O device such as disconnection or short circuit. It is an object of the present invention to propose a ship automatic control system that can effectively cope with a fault.

According to the idea of the present invention for achieving the above object, the present invention is a central processing unit for controlling the interpretation of instructions and processing of data calculation, comparison, etc., connected to the central processing unit via a network cable to the central processing unit A plurality of remote input / output devices for transmitting an input / output signal, a plurality of wires extending from each terminal constituting the remote input / output device, and a plurality of sensors / operating devices connected to the other ends of the wires.

Hereinafter, with reference to the accompanying drawings will be described embodiments of the present invention; The present invention is not limited to the embodiments presented below, the invention of the same range by addition, limitation, deletion, addition, etc. of components within the scope obvious to those skilled in the art to which the present invention belongs Could be.

2 is a view showing the configuration of a ship automatic control system according to the spirit of the present invention.

2, the automatic vessel control system according to the spirit of the present invention is connected to the central processing unit 100, the central processing unit 100 and the network cable 120 through the central processing unit 100 input and output A plurality of remote input and output device 110 for transmitting a signal, a plurality of wires 130 extending from each terminal constituting the remote input and output device 110 and a plurality of sensors connected to the other end of the wire 130 140 / actuator 170.

In more detail, the central processing unit and the remote input / output device 110 are connected through a network cable 120 to communicate with each other, and the remote input / output device 110 connected to one side of the network cable 120 is respectively. It includes a plurality of terminals to which a bundle of wires 130 for receiving signals from the plurality of sensors 140 are connected. The wires 130 extending from the terminals of the remote input / output device 110 may receive signals transmitted from the sensor 140 / operator 170 connected to each wire 130 via the remote input / output device 110. In order to transmit to the central processing unit 100, each transmission signal and the wire 130 is a one-to-one matching. However, since the remote input / output device 110 is connected to the central processing unit 100 through a network cable and is disposed in close proximity to the plurality of sensors 140 / operating device 170, the conventional wire 130 serves as a connection ring. There is no need to install a plurality of terminal boxes to perform a separate, it is possible to replace the wire bundle from the terminal box to the automation system with a network cable, between each remote input and output device 110 and the sensor 140 / operating device 170 It can significantly reduce the length and thickness of the wires 130 connecting the. In addition, due to the quantity of the plurality of terminal boxes and wires, which are conventionally formed, the connection portion between each wire 130 is increased, thereby increasing the number of converters and welding operations for fixing the wires or terminal boxes required for system construction. The same amount of incidental work can be drastically reduced by applying the ideas of the present invention. In addition, it is possible to drastically reduce the amount of work of the test work of the system built through the work and the cause analysis work when an error occurs.

On the other hand, the central processing unit (100) is a core device of the computer system that controls the processing of the interpretation of instructions, the operation of data, comparison, and the like.

More specifically, as a device for controlling the entire computer system, it controls and adjusts a series of processes that receive data from various input devices, process the data, and send the result to the output device. Since the operation of all the computers are controlled by the central processing unit 100 corresponds to the brain of the computer. In a medium and large computer, this is called a central processing unit 100, but in a small computer, it is sometimes called a microprocessor, or simply a processor. That is, the central processing unit 100 used to explain the configuration of the present invention may be variously modified within a range apparent to those skilled in the art, regardless of the name.

There are two types of microprocessors, depending on the type of instruction set. Complex instruction set computers (CISCs) offer a variety of instruction formats through microprogramming, but their complexity is expensive. Reduced instruction set computers (RISCs) are less expensive than CISCs and are primarily used in workstations by simplifying control logic to improve computation speed.

The CPU 100 includes an arithmetic logic unit that is in charge of comparison, determination, and operation, and a control unit that is in charge of interpreting and executing instructions. An ALU is an adder that performs various additions and results, an accumulator which is a register that temporarily stores the results of arithmetic and logic operations, and a kind of temporary memory in the central processing unit 100. It consists of a register or the like which is a device.

The control device sends a control signal to a program counter that controls the execution order of the program, an instruction register that temporarily stores the contents of the currently executing instruction, and decodes the instructions contained in the instruction register. It consists of an instruction decoder.

The central processing unit 100 collects and analyzes information necessary for voyage of the ship, and controls the ship's operation based on the analyzed data. For example, one or more sensors 140 collect information such as pressure, temperature, water temperature and fuel amount in the vessel, and monitor the driving state of the engine, the state of the fuel supply system, the state of the cargo tank, etc. through the information. It is possible to drive the operating device 170 to implement a stable operation of all the system, and displays the information to the system operator.

In general, the remote input and output device 110 is used to provide a communication connection between the microprocessor and the input and output devices. For this reason, most remote input / output devices 110 are programmed to accept various types of electrical signals. The remote input / output device 110 includes an external input / output terminal and an input / output interface. The external input / output terminal converts the electrical analog signal transmitted from each sensor 140 through the wire 130 into digital data recognizable by the central processing unit 100 or transmits command data given from the central processing unit 100. It converts the signal into a signal and transmits it to the operation device 170, and exchanges data with the control unit in the input and output interface, the input and output interface is connected to the central processing unit or other remote input and output devices through a LAN (Local Area Network). The control unit of the input / output interface may be implemented by a general central processing unit 100 or the like, and exchanges data with a plurality of input / output devices through a system bus. The input / output devices are detachable from the input / output interface, and transmit information received through the plurality of sensors 140 to the controller through the system bus or transmit a signal transmitted from the controller to the operation device 170. These I / O devices have different types (digital, analog, RTD, RPM, input, output, etc.) that require different hardware and software drivers to process them, each with its own access address. Each of the input and output devices may have address setters such as dip type switches for setting their own addresses, and the address may be set by software.

The plurality of remote input and output devices 110 may be connected via a mutual auxiliary wire 150. The auxiliary wire 150 disconnects communication with the central processing unit 100 only when a device in which an error occurs when an error occurs in a specific remote input / output device 110 does not affect other devices of a system in which the error is the same. Even if an abnormality occurs in the auxiliary wire 150 between the 110, the signal transmitted from the sensor 140 connected to the remote I / O device 110 in which the error occurs is diverted to another remote I / O device 110 to perform central processing. To the device 100. As the number of the remote input / output device 110 increases, the auxiliary wire 150 may effectively connect each remote input / output device 110 to the occurrence of an error of the device.

The present invention reduces the wire length between the remote input / output device and the sensor and the operating device by distributing the remote input / output device of the ship automation system to various sensors and the operating device in close proximity to each other. By reducing the number of wires, the use of wires is significantly reduced, and in the event of a failure of a conventional remote I / O device, it is impossible to transmit or receive a specific signal, thereby preventing errors that may occur at terminals of remote I / O devices such as disconnection or short circuit. It is effective to propose a ship automatic control system that can effectively respond.
