Technical Field
[0001] The utility model relates to the field of ships, and in particular to an internal communication system of a ship. Background Art
[0002] We have entered a new era of industrial revolution, whose hallmark features are digitalization and intelligence. As the demographic dividend disappears and labor costs become increasingly high, the level of digitalization and intelligence needs to be improved urgently. For the shipping industry, the research on smart ships is imminent. The realization of intelligence is inseparable from digitalization, and digitalization will be the foundation for the development of smart ships in the future.
[0003] Traditional internal communication systems on ships mainly include telephone systems, broadcasting systems, local area network systems, CCTV systems, master and slave clock systems, and television systems. Each system is an independent subsystem, including an independent main unit, regional control unit, and cables. The signal transmission forms of each system are not uniform, and additional external signal conversion is often required. Signal conversion will cause signal distortion and signal delay, and traditional analog signals are less secure.
[0004] In the field of ship electrical engineering, the internal communication system accounts for a very important proportion in terms of the number of equipment and cables. If the internal communication system is digitally upgraded, it can effectively improve the intelligence level of the ship and reduce labor and operating costs. Utility Model Content

[0007] In order to enable signal transmission between the modules, the telephone module, broadcasting module, local area network module, CCTV module, master and slave clock module and television module are connected through signal cables.
[0008] In order to supply power to each module, the main unit also has a power supply module for supplying power to the telephone module, the broadcasting module, the local area network module, the CCTV module, the master / slave clock module and the television module.
[0009] Preferably, the main unit has a network chip that can realize networking of the entire internal system.
[0010] In order to realize real-time reading and remote maintenance of the data of the internal communication system on shore, the local area network module is connected to the satellite communication system.
[0011] Preferably, each terminal device of the internal system is assigned an IP address. In this way, the playback of a certain or a certain part of the broadcast speakers can be set, the image information captured by some cameras can be read through the IP address setting, and the time display of the sub-clock can be set through the IP.
[0012] In order to reasonably allocate the positions of the digital signal distributors, the digital signal distributors are at least partially arranged on the deck of the ship, in the engine room and at the bow.

[0015] Figure 1 It is a schematic diagram of the structure of the internal communication system of a ship in an embodiment of the utility model. DETAILED DESCRIPTION
[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0017] like Figure 1 As shown, a ship internal communication system of this embodiment includes a main unit 1, a digital signal distributor 2 and an internal system 3.
[0018] The internal system 3 includes a telephone system, a broadcasting system, a local area network system, a CCTV system, a master-slave clock system and a television system. The terminal devices of the above systems are telephone, broadcasting, local area network socket, CCTV, master-slave clock and television socket.
[0019] The main unit has a telephone module 11, a broadcast module 12, a LAN module 14, a CCTV module 15, a master / slave clock module 16 and a TV module 17 corresponding to each internal system. Each module is a signal processing unit corresponding to the internal system. Each module can exchange data within the main unit, reducing the laying of external cables and the installation of cable welding parts, and reducing the empty ship weight to a certain extent.
[0020] The digital signal distributor 2 is arranged on the ship deck, in the engine room and at the bow. The main unit 1 is arranged in the equipment room. Of course, the digital signal distributor 2 is not limited to the above areas and can be flexibly arranged according to the number and location of the terminal equipment of each internal system. The digital signal distributor 2 is shared by 6 systems with a unified form and signal, and is used for the distribution of digital signals.
[0021] The main unit 1 leads the digital communication cable to the digital signal distributor 2, and the digital signal distributor 2 is connected to the terminal equipment of each internal system through the digital communication cable. Compared with the traditional design where each cable goes directly from the main unit to the terminal equipment, the entire system can save 1 / 3 of the cable length.
[0022] The telephone module 11, the broadcast module 12, the LAN module 14, the CCTV module 15, the master / slave clock module 16 and the TV module 17 are connected by signal cables. The information transmission between the systems, such as broadcast and telephone, is connected by cables inside the main cabinet, and the signal interaction problem between the systems is solved inside the main unit 1, reducing the laying of external cables.
[0023] Both digital communication cables and signal cables are digital network cables. The entire internal communication system can achieve synchronous transmission of multiple signals without interfering with each other, making full use of the stable performance and strong anti-interference ability of digital network cables. In addition, the POE power supply characteristics of the network cable can achieve simultaneous transmission of signals and power, without the need to lay out additional power cables for the system, reducing the cost of cable procurement and laying, and to a certain extent, reducing the weight of the empty ship.
[0024] Compared with the traditional design where each system requires an independent main unit and cabinet, after digitization, the six systems share one main unit by centrally arranging the modules.
[0025] The main unit also has a power supply module 18 for supplying power to the telephone module 11, the broadcasting module 12, the LAN module 14, the CCTV module 15, the master / slave clock module 16 and the TV module 17, and supplies power to each system via the network POE.
[0026] Each system is packaged and supplied by one manufacturer. The network hub of each system is installed and debugged in the main unit. The IP address of each device is allocated before leaving the factory, which reduces the signal interface verification time in the drawing design stage and shortens the service provider's debugging cycle.
[0027] Through the reasonable allocation of IP addresses, each phone, broadcast speaker, camera, master and slave clock, network socket, and TV socket are assigned an IP address. Through the setting of IP addresses, terminal devices can be controlled: control the playback of a single or partial area broadcast, control the display of slave clock time, and read the audio and video information of a certain camera. For example, you can set the playback of a certain or partial broadcast speaker, read the picture information captured by some cameras through the setting of IP addresses, and set the time display of the slave clock through IP.
[0028] The main unit 1 has a network chip 13 that can realize the networking of the entire internal system. The local area network module 14 is connected to the satellite communication system 4, which can realize real-time reading and remote maintenance of the internal communication system data on shore.
[0029] After connecting to the external network, the signal of a single terminal device can be read in real time or retrieved by shore staff through IP addressing. Internal communication system failures can be transmitted to the shore working base station through the network, enabling remote diagnosis, maintenance and troubleshooting without docking, thereby improving ship operating efficiency and reducing operating costs.
