Description

A information service method and processor and system and terminal for prevent a accident at sea}

The present invention relates to a method and system for more effectively preventing marine accidents such as collisions and stranding using information technology.

It is well known that the sea not only plays an important role as a trade route but also as an important source of food for the public.

Although marine accidents occurring at sea affect the marine ecosystem to be passed down to the descendants, it is obvious that they should be reduced, but marine accidents are not easily reduced despite modernization of ship navigation equipment and improved awareness of workers. Is an information technology that allows information to be exchanged between fishing vessels and merchant ships or provides efficient navigational information.

Merchant ships and fishing vessels that operate economic activities at sea will be called economic activities themselves, but as their purpose is different, they have different moving properties, which is why the collision between fishing boats and commercial vessels is not fundamentally resolved. Do.

In general, a merchant ship sails along a defined route, while a fishing vessel can work at any position on the sea for fishing purposes. In addition, a fishing vessel can always use fishing gear due to its characteristics. It is also common to reach this range of several hundred meters.

In this situation, if a commercial ship, which is a relatively large ship, approaches the side of the fishing vessel, it will cause an accident that damages the fishing gear or collides with each other.In the case of fishing vessels, the search for fish is the main concern, and the merchant ship is indifferent to the shipping route. In this case, there is a weakness about maritime collision in that it is too late to understand various phrases, but in this case, "Radar" which is replaced by the automatic watch system, also prevents microwave propagation. As a result, they find that the fishing gear locked under the sea surface cannot be detected and is practically useless.

The means to supplement this would be to establish a bilateral information exchange system so as to be able to immediately contact in case of emergency, but analyzing the existing communication systems installed on fishing vessels and commercial ships, it is not easy to communicate information between the two sides.

In other words, conventional communication equipment currently installed on fishing vessels and commercial vessels consists of different communication systems for different purposes-in the case of fishing vessels, the purpose of securing a radius of fishing work with nearby fishing vessels and fishery information to be referred to in search of fish. Merchant ships are used primarily for the purpose of communicating with the land.-Even though some communication channels (ie, 2183.4KHz and 2639.4KHz and 27822.4KHz for radiotelephones) can be allocated, Due to the use of separate channels, the actual mutual communication setting is difficult to expect.

For merchant vessels, the Global Maritime Distress Safety System (GMDSS), Digital Selective Calling (DSC), established by the International Maritime Organization (IMO), identifies all vessels. It is a facility that allows the central control room to know the position of all ships by periodically reporting the location by digital communication method that has been assigned a symbol (ID) (ID). However, when all ships are called to simply establish communication with an unknown ship whose communication partner's ID is not known, there is a possibility that the entire communication network may be exchanged in consideration of distress communication. This is because the proposed technology is focused on.

On the other hand, the 2-tone alarm signal, which is additionally provided in the conventional transceiver, simply informs all the ships of the alarm signal, and there is a lack of informing which ship it is from. .

The Automatic Identification System (AIS), which is an improvement of the DSC, includes a ship's position, course, speed, ship state, and the like measured by a GPS (Global Positioning System). It is enacted so that all ships at sea can understand each other's dynamics by carrying out other information and carrying it together and distributing it to all ships.

The Automatic Identification System (AIS) is a Time Division Multiple Access (TDMA) using VHF Band that enables communication between 2,250 ship-to-ship or ship-to-shore control systems per minute. As a display method, the ship is displayed on the Electronic Navigation Chart, and in the case of merchant ships, navigational information is reported at least every 6 minutes, which is an excellent function compared to the conventional system. Illustrated in FIGS. 1 and 2.

However, in the case of fishing vessels, the application of these facilities is not only expensive, but unlike the commercial vessels that travel along the coast, there is a problem that microwave communication cannot reach when navigating a distant sea, and especially the exposure of fishing place related to the fishing industry It is not easy to apply it to fishing vessels in that it cannot directly provide the information required by the fishing grounds, but it is compulsory for the maritime organization to mandate the system. No consideration is given to fishing vessels because it does not address this.

Considering the nature of fishing vessels, the future information and communication facilities satisfying the requirements include Korean Patent Application No. 1997-022694 (filed on June 2. 1997), Korean Patent No. 1998-0000155 (filed on January 7, 1998), 10-1998-0000632 (filed Jan. 13, 1998), JP 1998-035454 (filed Aug. 31, 1998), JP 1998-035455 (filed Jan. 31, 1998), JP 1998-043267 Digital Fishing Network (DFN) of wireless data communication function using HF Band established by (October 16, 1998) and 1999-0005438 (February 18, 1999) It is a function that automatically collects the GPS position of fishing vessels and various fishing conditions at the interval of about 4 hours suitable for fishing vessels and provides advanced fishing information represented by texts and pictures. Similar to the identification system (AIS), it is based on the electronic chart and expresses various information thereon. If you use this technique because it is able to know that it is possible to achieve the basic conditions that can contribute to preventing maritime accidents.

A block diagram of a digital fishery communication network (DFN) and an example of the screen thereof are shown in FIGS. 3 and 4.

Another important maritime accident is a stranded accident that occurs when you are sailing off the coast. This is mainly due to a lack of understanding of the signposts using light or sound from the lighthouse, or failure to properly function on the vessel in service. It is easy to get up.

The International Maritime Organization (IMO) is a navigational information text broadcasting (NAVTEX) called "NAVTEX", which makes it possible to broadcast texts related to vessels in service, including maritime traffic broadcasting provided by the Korea Maritime Police Agency. Although it is being implemented, the utilization of the offshore fishing vessels is inevitably low in that it will not be able to obtain a great effect compared to the new equipment cost due to the functional limitation that only a small amount of data such as navigation information can be handled.

On the other hand, the fishing service station in charge of fisheries communication in Korea provides navigational information by voice communication, but it is a fishery support organization that operates in a different system from the dedicated agency in charge of maritime rescue (Marine Police Agency). In terms of the quality of the service, the operation is largely different, which means that fishing vessels without NAVTEX are not actually provided with navigation information service.

Fig. 5 shows an example of a fishing boat transceiver, which is a mandatory facility for communicating with the existing voice communication, and a merchant ship transceiver, which is a mandatory facility for radiotelephones on board.

In order to improve the above problems, it is necessary to study a new system, and the improvement of this problem is particularly natural because it will have an informatization effect on a large number of fishing vessels.

The first object of the present invention is to combine a ship automatic identification system (AIS) suitable for the actual conditions of the commercial vessels and a digital fishing communication network (DFN) suitable for the actual situation of the fishing vessels with information technology, so that this type of vessels, such as merchant ships and fishing vessels, The purpose is to provide a preventive means of marine accidents to observe the mutual movement situation,

The second object of the present invention is to provide a technical means that can immediately respond to an emergency situation by providing a technical means that allows merchant ships and fishing vessels constituting different communication systems in the sea to quickly establish communication in an emergency situation.

A third object of the present invention is to provide an information technology means for directly expanding service users without expanding personnel by automatically converting navigation information provided by text broadcasting into voice and providing the same in parallel with a transmission device of this type.

The fourth object of the present invention is to achieve the effect of cost reduction and early implementation of the service by making it possible to immediately implement the existing communication terminal device to maximize the use in configuring such a means, at a low cost,

The fifth object of the present invention is to overcome the heterogeneous management system and to provide a condition for collectively integrating related systems in order to provide a uniform service to users of terminal devices in different environments.

The present invention for this purpose is a combination of heterogeneous information communication network (AIS) and digital fishing communication network (DFN) as a protocol converter (Protocol Converter) to collect all from the fishing vessel through the digital fishing communication network (DFN) From the operation information and operation information, only the flight information related to the operation safety of the merchant ship is selectively extracted and provided to the merchant ship through the ship automatic identification device (AIS), and collected from the merchant ship through the ship automatic identification device (AIS). By selectively extracting only the flight information related to the operational safety of the fishing vessel from the status information and the operation information, and providing it to the fishing vessel via the digital fishing communication network (DFN), the heterogeneous wireless communication environment satisfying each condition is interconnected and its purpose It provides a means of selectively exchanging safety information only without being impaired.

In addition, the present invention provides a means for calling and linking fishing vessels and merchant ships composed of different communication systems in the sea as a common channel, and automatically selects a related channel when an alarm signal is generated by manually selecting a channel in an emergency situation. Alarm signal processing that improves the existing DSC or audible distress signal as a means to automatically establish communication by receiving automatic alarm receiver that scans alternately and displays appropriate alarm and counterpart information. Provide means,

Furthermore, when an emergency occurs, when the alarm signal is generated by alternating the transmission channel automatically as well as the position measured by GPS, the receiving party analyzes the position spatially by using the output of the auto repair device and then surrounds his / her surroundings. It provides a variety of complex information technology and control means to establish a quick and accurate communication setting by determining whether the signal is an emergency signal.

Accordingly, the present invention further provides a means for automatically receiving the alarm signal received by the counterpart.

In another aspect, the present invention provides a means for providing navigation information provided by text broadcasting as well as voice by connecting a NAVTEX server and a fish communication communication device for voice communication using a TTS (Tex To Speech),

Furthermore, by providing a means for transmitting a predetermined broadcast information at a predetermined time to provide a means to periodically broadcast without interference to the existing fishing communication, and provides a means that can be configured as a separate transmission device.

In addition, the present invention is further configured to collect all the situation through all means and to be serviced by all means by integrating and connecting the above means, but in such a facility, the equipment and operating system installed in the existing fishing vessel It provides a means to combine cost-effectively and quickly, by interworking with the associated communication network optionally to use as it is.

A fishing boat digital fishing communication network 2 of means configured to collect various information from the fishing boat 1 and to provide various information to the fishing boat 1;

A ship automatic identification system 4 of a means configured to collect various information from the merchant ship 3 and to provide various information to the merchant ship 3;

A protocol converter (5) for selectively extracting only mutually necessary information from the information of the digital fisheries communication network (2) and the ship identification system (4) and providing the environment suitable for mutual transmission and reception conditions;

By using the protocol converter 5, the digital fishing communication network 2 and the ship automatic identification system 4 are connected to the information communication network so that fishing vessels and merchant vessels of the sea can interconnect mutually necessary information.

In FIG. 6 configured as described above, a more detailed configuration may be additionally designed, but the operation of FIG. 6 showing a conceptual configuration will be described below.

Normally, a merchant ship is a ship's automatic identification system (AIS) as shown in Figure 1, as mandated by the International Maritime Organization, and its ship specifications, location, course, speed, sailing conditions, cargo, etc. Status information will be notified to the central control center and all other ships, and other merchant ships can use this information to monitor the dynamics of other ships to predict their risks in advance.

This is possible because there is no problem in the economic activity of the merchant ship, even if the information they sail is known to other ships.

In contrast, fishing vessels have not been mandated by the International Maritime Organization, which means that if other fishing vessels are aware of the details of the vessel's movements or loaded cargo (catch), a large number of fishing vessels are likely to be raised or likely to be raised. This can be fatal to fishing boats' livelihoods.

With this in mind, the Digital Fishing Network (DFN) aims to collect data for fish stock management and to provide advanced fishery information (characters and pictures) to improve the efficiency of fishing vessels, as illustrated in Figure 3. It is operated by.

The information collected for fisherman management here includes, of course, the vessel's ship specifications, location, course, speed, type of industry, fish species, catches, the number of misses, and other information. It fully reflects the position of fishing vessels to be kept as confidential as possible at intervals of 4 hours or more, and maintains individual security of industry, fish species, effort, and catches among the collected information.

This means that the automatic identification system and the digital fishing communication network are heterogeneous systems that are completely different in terms of confidentiality and function of information. If left in this state, fishing vessels and commercial vessels may cross each other at sea. Even so, it is difficult to know each other's dynamics in advance.

Accordingly, the present invention according to the embodiment of FIG. 6 performs the function of selecting and linking only the necessary information to each other as the protocol converter 5, and providing only the ship specification and the position of the information collected from the fishing vessel to the ship automatic identification device (AIS). By adding course and speed as needed, only minimal information is provided to the ship's automatic identification system (AIS) so that this information can be transferred to the merchant ship.

In addition, the protocol converter 5 provides almost all the information except the freight information among the information collected from the merchant ship, that is, the ship specification, location, course, speed, navigation status, etc. to the digital fishing telecommunication network (DFN) to provide this information to all fishing vessels. You will be notified.

Here, the digital fishing communication network (DFN) can also be informed including the operation status of other fishing vessels collected by its own communication network, but the fishing vessels are more suspended for work than when they are actually operated and also It is also related to the livelihood of the company, so it can be applied variably depending on the situation.

Since the protocol converter 5 is not physically present but is composed of packet data creation algorithms, which are computer software, the change in accordance with the above situation does not mean that a separate additional device is connected or removed. Quench operation includes the meaning of adding or removing frames of packet data.

This information linkage seems to be simple at first glance, but as a practical effect, a commercial ship moving at high speed using only a digital fishing communication terminal without having a separate expensive equipment on the fishing vessel and a separate function of an automatic vessel identification system (AIS). You can quickly and accurately observe the operating conditions of all fishing vessels, and you can get an excellent effect. You can connect the heterogeneous microwave communication network (AIS) and the shortwave network (DFN). This is an invention in which a large number of users using each communication network does not have a cost burden such as purchase of a separate terminal device, thereby obtaining a maximum effect at a low cost.

7 is a block diagram showing an exemplary embodiment of the present invention for facilitating communication setup between unknown ships facing the sea.

Conventional first and second receivers 6 and 7 installed on the ship;

Satellite positioning device (8) is installed on the vessel if necessary;

An alarm signal transmitter 9 which is connected to the satellite positioning device 8 and may include positioning data, if necessary, and is connected to an input terminal of the first transmitter and constitutes means for generating a specific alarm signal in case of an emergency;

It has a function to monitor the signal transmitted from the first transmitter, and monitors the signal of the channel normally set, and then catches a specific alarm signal generated from the first transmitter 6 in an emergency to inform the fact that the alarm signal is captured by a message. Or auto repair receiver 10 of a means configured to notify the fact with electronic chart 11 or, if necessary, to perform an automatic voice playback function if necessary;

If necessary, it is connected to the automatic maintenance device, and the positioning data from the satellite positioning device 8 is displayed as coordinates on the electronic chart, and it is analyzed whether it is a signal generated near its own position, and the result is displayed as a message and automatically An electronic chart system 11 which performs a function of generating a response signal;

When the alarm signal by the alarm signal transmitter 9 is captured, it is configured to artificially call or automatically answer the other party by using the second transmitter 7.

The present invention configured as described above is described as follows.

Due to the small size of fishing boats that are damaged during collision at sea, it is not easy to find them by radar unless special care is taken by merchant ships, and because fishing boats are floating around unspecified places, it is difficult to predict them in advance. There is a difficult problem.

In such a situation, it is easy for a fishing boat worker to find a merchant ship, a relatively large object, with the naked eye or radar. If the merchant ship is approaching a course that may cause harm to him, The alarm signal transmitter 9 of the present invention is operated.

By this operation, the alarm signal transmitter sends out an alarm signal as a specific signal. The alarm signal is mainly composed of audible frequency, such as "beep-po-", FSK (Frequency Shift Keying) or DTMF (Dual Tone Multi Frequency). It is generated by a signal.

However, the means for constituting such an alarm signal specifically includes the addition of a communication link setting request signal as the broadcast means or a communication link setting request signal as an audible frequency alarm signal to the function of the DSC which broadcasts only the existing distress signal. Although it is applicable to those skilled in the information and communication field, only those conceptual descriptions are well known, and thus are not described in detail. However, the present invention is not limited to a specific code of any one method known in the art. It also includes a means for monitoring the approach of the means monitored by means and radar to automatically approach the alarm signal, which is not limited to any one means.

The alarm signal is supplied to the first transmitter and is modulated and transmitted to a channel that can be commonly received by several ships or to a specific channel given a clear obligation under international law. In this way, the alarm signal transmitter 9 also controls the first transmitter. Is not limited because the channel of the first transmitter may be automatically changed and transmitted to various channels or specific channels.

The alarm signal includes an emergency communication link setting request signal as a means other than a distress signal that automatically accompanies an automatic relay action or an automatic response action. A message containing the coordinates of, and its identifier (ship number, etc.) and other emergencies such as collision / distress / can also be delivered as an audible frequency or data signal.

The modulated output from the first transmitter 6 is transmitted to the auto repair receiver 10 of several ships sailing in the vicinity, and when the auto repair receiver 10 is activated to capture an alarm signal, Radar surveillance is thoroughly conducted to artificially check where the emergency ship is.

If the alarm signal transmitter 9 transmits its coordinates and the identification symbol together, the vessel receiving the alert signal can immediately know which ship is using the message of the auto repair signal, and the neighbors to which they sail. It is also possible to know whether it is a vessel of the ship, and it is possible to easily call the ship sent by tracking the channel according to the situation judgment, and if it is an alarm signal related to the operation of a specific counterpart, the specific counterpart system recognizes it and performs an automatic response system. By driving, it is possible to secure clear communication settings with each other.

In the case of a large commercial ship with advanced equipment, the output of the automatic repair and repair device 10 is preferably connected to the electronic chart 11 to perform spatial analysis with a geographic information system (GIS) function of the electronic chart. It is also possible to determine whether it is generated from a ship within a certain range and to ensure rapid accuracy by the automatic control function. This spatial analysis function uses the interface of the existing electronic chart display and information system (ECDIS) and software. Corresponds to an extension to the data link feature.

The present invention of FIG. 7 has an effect of establishing a situation in which unknown ships do not know which ships are approaching each other as simple facilities, wherein the automatic repair / receiver receives a warning signal as a message. By latching, it may be configured to continuously examine other channels to continuously express a message or to automatically wait on the channel where the alarm signal is detected.

When the alarm signal is generated using a specific code rule, the auto repair receiver receiving the alarm signal generates a voice alarm message corresponding to a specific code and automatically responds using the same. The code signal is also used in a multinational language. Since the present invention can be configured to be reproduced, the present invention can be utilized as a device for receiving voice information anywhere in the world.

8 is an example showing a system configuration for providing a conventional NAVTEX character-type navigation information in parallel by using a text / voice conversion device,

A conventional transceiver 6 or 7 provided on the ship;

A transmitter 12 installed on land;

A NAVTEX system 13 for providing text information on the sea;

It is connected between the NAVTEX system 13 and the transmitter 12 and automatically converts the information provided by the text from the NAVTEX into the voice of a set rule to supply it to the transmitter 12, and transmits it as a voice signal propagation by driving the transmitter under the set conditions. A text-to-speech converter 14 to make it possible;

It is configured to receive the voice signal radio wave transmitted from the transmitter 12 as the transceiver 6 or 7.

FIG. 8 is configured to automatically convert the navigation information of the NAVTEX to the text-to-speech automatic conversion device, and automatically controls the transmission start key of the transmitter and, if necessary, the channel, and distinguishes a given broadcasting condition from a male and female voice. And since the speed of the voice is set, after the text is supplied, the voice signal is automatically reproduced according to the conditions set by the user and the transmitter is controlled to broadcast the information by radio waves.

In Fig. 8, the configuration in which the NAVTEX is connected to the text-to-speech reproducing apparatus includes all means for interconnecting, despite being remote, as an information communication network using packet data.

The effect of the embodiment of FIG. 8 is to interconnect the NAVTEX and the fishery communication which are operated by different institutions, and to provide the same information even though the multimedia is simple. Especially, in the case of expanding various functions of the NAVTEX, In connection with the conventional fishing network, there is an advantage that it can serve as it is without changing the facilities of all fishing vessels.

The present invention of the eighth embodiment also includes a self-selective configuration capable of transmitting radio waves by adding a separate apparatus from other coast stations or NAVTEX broadcasting stations for commercial ships.

The term 'transmitter or transceiver' used in the present invention refers to a device for transmitting or receiving radio waves, and the term “transceiver” includes all means used only as a transmitter and configured as a receiver according to a use purpose.

In addition, in the term of the present invention, broadcasting information by using the information of NAVTEX is a term that includes all means of using the information of NAVTEX as it is or using only a small part, and ultimately whether or not it is used in NAVTEX. It is a term that includes all the character forms created for this purpose.

9 and 10 illustrate a flowchart and a hierarchical structure diagram of the information processing method of the present invention shown in FIG. 6 as an example, and the embodiment of FIG. 6 will be described in the following manner.

As shown in FIG. 10, the present invention is composed of four steps, a data collection step, an information extraction step, a mutual connection step, and a transmission step.

Each system is operating normally

The data collection step, which is the first step, collects various situation information of each ship as separate periods. (101, 102)

As described above in the description of FIG. 8, this process is a process of collecting information from the digital fishing communication network (DFN) and the ship automatic identification system (AIS) so as to suit the conditions of fishing vessels and commercial vessels, respectively.

In addition, it can automatically collect the route markers collected from the route marker facility using the sensor and transmit them at a later stage.

The second step, the information extraction step, extracts only the necessary flight information from among the collected information.

This process includes ship specifications, position, course, speed, and can be selected to vary according to the need as described above in the description of FIG.

However, it is efficient to send only the ship number for the specifications of the ship, because the ship number is the key value in all ships, and the remaining static information can be stored in advance and retrieved when necessary.

If there is a disturbance in the route marker, this information is automatically or additionally inserted into the interlinked content.

The third step, the interconnection step, is a step of exchanging information as a protocol between an automatic identification system (AIS) and a digital fishery communication network (DFN).

The functions used in this process are mainly to exchange information with the OSI7 layer or TCP / IP transmission environment, and both of them transmit header, address, control, information, and FCS information as an exemplary structure.

The reason for this protocol is to transmit information without loss between remote sites and to match heterogeneous communication systems if necessary.

In the fourth stage, the transmission stage transmits information using a digital fishery communication network (DFN) and an automatic vessel identification system (AIS) under conditions suitable for each vessel. (105, 106)

In this process, information is transmitted according to the characteristics of each communication network. As a result, various heterogeneous wireless communication networks used at sea can be interconnected with information communication technology installed on land.

Here, the control system of the onshore automatic identification system (AIS) or digital fishing communication network (DFN) manages the fishing vessel with the electronic chart system functions shown in Figs. If anticipated, the vessel may be called artificially or automatically to indicate the danger, and this process includes all of these means.

11 and 12 are flowcharts and hierarchical diagrams showing the operation of the embodiment of the invention of FIG. 9 according to the present invention. According to the present invention, an alarm transmission control step, an alarm generation step, a transmitter control step, an alarm detection step, and a communication are shown. It can be seen that it consists of five steps, which are execution steps.

In the first step, an alarm call control step is a step of driving a communication link setting request alarm by recognizing an emergency situation (202, 203).

This process includes all means to recognize the emergency situation with the naked eye and to manually control the transmission or to recognize it with the instrument.

The alarm generation step, which is the second step, generates an alarm signal for requesting communication link setting under a given condition based on the result of the first step. (204, 205, 206, 207, and 208).

In this process, if no condition is set or no additional function is provided, only minimum alarm signal is made, but other additional information can be added to increase efficiency. Digital data such as name, GPS measurement location, and other alarm status messages.

An example of the case in which the alarm signal is composed of the packet data having the most desirable configuration is shown in FIG. 13, which is easily understood by those skilled in the art, and thus the detailed description thereof will be omitted. The use shown is meant to include means for controlling the transmitter to automatically switch to a particular channel prior to sending the packet.

Information data blocks are also used to inform the specification of new ships.

In the third step, the transmitter control step transmits an alarm signal by controlling the transmitter to match the radio wave environment.

In this process, an alarm signal is automatically sent by controlling a press to talk key, but the transmitter key is operated several times for a set time and then operated again at intervals. The key is operated so that the user does not interfere with the operation of the reception function.

Of course, if communication with the other party is established after the operation of the alarm signal transmitter, the user can immediately stop the operation of the alarm signal transmitter.

In principle, the transmitter control function may be configured to emit an alarm signal to a specific common channel. However, in consideration of the reception capability of the other party, the transmitter control function may be provided with means for transmitting all the common channels or all channels alternately as necessary. .

Preferred frequencies for alarm delivery are efficient using a few common channels in the 2 MHz to 3 MHz band, the 4 MHz band, the 8 MHz band and the 27 MHz band.

In the fourth step, the alarm detection step is a step of automatically detecting the alarm signal generated in the third step (210, 211, 212, 213, and 214).

In this process, it detects the alarm signals promised to each other and generates a message. In the case of a simple alarm signal, only the visual and audio alarm messages including the received channel are generated. If the situation is optimal, the ship number and radio call name of the other party are included, and more preferably, it distinguishes whether or not it belongs to the area on the electronic chart, and automatically displays various received information or ship specifications including the ship number on the screen. The searched information can be displayed together.

If you want to sound the alarm message by voice, in this process, the pre-stored voice signal is searched and played back by condition.

The fifth step, the communication setting step, is a step in which communication can be performed until the end of the situation by calling the other party according to the alarm detection result and setting up the communication. (215, 216)

In this process, the other party is called by using the channel where the alarm is generated, but the auto repair device automatically detects the alarm signal and automatically controls the transmitter channel so that the user can use the microphone to establish a communication and automatically responds. It may optionally include both means for transmitting a signal and various means for artificially establishing a communication in accordance with a communication channel.

In the process up to this point, it is possible to set up initial communication with the mechanical automatic control function and to deal with the situation artificially thereafter.However, in the 4th or 5th step, the alarm detection status is automatically stored and verified later. You can additionally apply the Black Box function, which allows you to search by data.

14 and 15 are flowcharts and hierarchical structure diagrams of the present invention, which is an example of the embodiment of FIG. 8. Accordingly, it can be seen that FIG. 8 of the present invention comprises three steps of a broadcasting operation step, a transmission step, and a transmission step. .

In the first step, the broadcast operation step is a process of making text information to be broadcast into a file and setting a given broadcast condition (302, 303).

In this process, broadcast scenarios such as the process of unpacking text-type characters into language-type texts or the process of setting the channel to be broadcasted and the process of setting the broadcast time, are performed in order for the text-to-speech to play smoothly. The process of writing.

This process includes a sub-layer broadcasting information collection step, which includes not only the collection of textual information provided by NAVTEX, but also the failure situation from other route marking systems (sensors) and the digital fisheries communication network (DFN) or automatic vessel identification system ( Means for collecting sea situation information from AIS).

Of course, this operation may be configured to be performed again in the second step or only in the second step.

A transmission step, which is a second step, is a step of transmitting and receiving information by designating a broadcasting system to be transmitted by radio waves. (304, 305)

In this process, it is to receive and store the file worked as the first step. Preferably, it is efficient to separately classify and store the text file which is the broadcast data itself and the data file containing the broadcast scenario.

The first and second steps may be integrated depending on the program design.

In the third step, the transmitting step is a step of converting a text into voice using a file received in the second step and performing a final service. (306, 307, 308, 309).
