Description

Multifunction walkie-talkie for forest fires}

The present invention relates to a multi-function radio used in a forest fire, and more particularly, in addition to a radio telegraph function, which is an inherent function of a radio, an automatic transmission function of ambient temperature, an automatic transmission function of location information, and a relay function for extending the communication range. It is about a special-purpose radio that can be helpful in extinguishing a forest fire by performing and automatically performing a rescue request function under specific conditions so that it can also help in the rescue of firefighters facing an emergency situation.

In general, at a forest fire site where a spread range is very wide compared to other fire sites, the distance between firefighters dispatched to the scene and the distance between firefighters and the command center may become very far.

Therefore, although a relay device is used to secure the communication distance, it is difficult to place a relay device in the right place according to the situation that changes every moment. Therefore, there is a problem in that radio communication between firefighters or between firefighters and the command center is interrupted. can happen

Since these problems hinder the establishment and execution of evolutionary operations in a situation where it is difficult to secure aerial images, efforts have been made to solve them from before, and as a result, Korean Patent Laid-open Publication No. 10-2008 -0064435, "Voice relay radio and voice relay system using the same" and Korean Patent Laid-Open Publication No. 10-2022-0088287, "A radio device having a repeater function and a method for transmitting and receiving the same signal" have been proposed and disclosed. .

First of all, in the “voice relay radio and voice relay system using the same” of Korean Patent Laid-Open Publication No. 10-2008-0064435, the communication range of the radio to be transmitted crosses the communication range of the radio to be received. The present invention relates to a system configured to use a radio located within a range as a repeater, and as a result, an effect of extending a communication range.

In addition, in Korean Patent Publication No. 10-2022-0088287, "A radio device having a repeater function and a method for transmitting/receiving a signal therefor", radios out of communication range use a third radio as a repeater to signal a signal. An invention related to an apparatus and method capable of transmitting and receiving has been proposed.

However, only the above-described prior inventions can solve only some of the problems of communication failure among various problems occurring at forest fire sites, and there are still many problems to be solved.

That is, as described above, at a forest fire site where the spread range is very wide compared to other fire sites, information such as the size and direction of the forest fire is confirmed through aerial images and used for extinguishing operations, but flight at night or in bad weather In this difficult situation, it is difficult to secure aerial images until the day is bright or the weather improves.

In addition, although a life-threatening situation may occur in which firefighters are damaged by rapidly spreading forest fire or toxic gas, rescue may be delayed because the command center cannot quickly grasp the situation.

In this way, it can be said that a solution to this problem is needed because not only the problem of communication failure but also various other problems may occur at the site of a forest fire.

Republic of Korea Patent Publication No. 10-2008-0064435 (2008. 07. 09) Republic of Korea Patent Publication No. 10-2022-0088287 (2022. 06. 27)

The present invention is an invention proposed for the purpose of solving various problems occurring at forest fire sites,

At forest fire sites, where the spread range is very wide compared to other fire sites, information such as the size and direction of the forest fire can be checked through aerial video. There may be problems that make it difficult to obtain information,

The present invention relates to a multi-function radio used at a forest fire site,

a temperature sensor 100 that measures ambient temperature and generates temperature information; a tilt sensor 110 that detects a tilt and generates tilt information; a location information module 120 generating location information using a satellite positioning system; The temperature information is transmitted to the outside along with the location information, and the slope information is checked to generate an emergency signal to request rescue when the slope change does not occur for more than a preset time in a state where the slope information exceeds the preset slope value is confirmed. A control unit 130 to be transmitted to the outside together with the information; and a wireless telegraph unit 140 that performs functions for radio telegraphy including transmission of temperature information, emergency signals, and location information; It is characterized in that it is configured to include.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First of all, the multifunctional radio for forest fire sites according to the present invention is a communication equipment provided to firefighters dispatched to the site of a forest fire, and in addition to the radio telegraph function, which is the original function, an automatic transmission function of ambient temperature and an automatic transmission function of location information, and It is characterized in that it is configured to implement an automatic rescue request function for firefighters in need of rescue.

Therefore, the radio 10 of the present invention has the same or similar appearance as other conventional radios and includes the configuration for performing the radio telegraph function, which is its original function, as it is, but automatically transmits the ambient temperature and location information. It should be configured in a form in which the configuration for the function and the automatic rescue request function is added.

More specifically, as shown in FIG. 1, the radio 10 of the present invention is provided with a temperature sensor 100 for generating temperature information by detecting ambient temperature, and generating location information using a satellite positioning system. A location information module 120 is provided, and a tilt detection sensor 110 for generating tilt information by detecting a tilt is provided.

At this time, the temperature sensor 100 should be provided at an advantageous position for measuring the ambient temperature in consideration of both a state in which the radio 10 of the present invention is mounted on firefighting clothes worn by firefighters and a state directly held by firefighters. However, there is no particular restriction on the locations of the location information module 120 and the tilt sensor 110 .

That is, the temperature sensor 100 is preferably provided at the top of the main body of the radio 10 or on the front part of the upper side to be advantageous in measuring the ambient temperature, and a part of the temperature sensor 100 is included in the radio 10 to enable more rapid measurement of the ambient temperature. It may also be provided in a form exposed to the outside of the main body.

In addition, the radio 10 of the present invention may additionally include a detection sensor for detecting the concentration of carbon monoxide and generating carbon monoxide concentration information. In this case, the concentration information together with the temperature information may be transmitted to the outside.

And as shown in FIG. 2, the location information module 120 is a GNSS module for use of a Global Navigation Satellite System (GNSS) including Global Positioning System (GPS), GALILEO, and Global Navigation Satellite System (GLONAS) ( 121) and a location information generation unit 122 that generates location information using a first-rank satellite signal having the highest reception sensitivity among satellite signals received through the GNSS module 121.

That is, each satellite signal of GPS, GALILEO, and GLONAS, which constitutes GNSS, changes in reception sensitivity according to the position of a satellite that changes frequently, and the better the reception sensitivity, the more precise location information can be generated.

Therefore, the present invention allows more precise location information to be generated than location information generated using GPS alone through the configuration of the GNSS module 121 and the location information generator 122, and additionally specific It is designed to flexibly respond to unexpected situations in which reception of satellite signals is interrupted.

That is, in an unexpected situation in which reception of GPS satellite signals is cut off, location information using satellite signals of GALILEO and GLONAS can be continuously generated, and when reception of GPS satellite signals is resumed thereafter, all of GPS, GALILEO, and GLONAS are restarted. It is a configuration in which the generation of the satellite signal used occurs.

At this time, since the GNSS available through the GNSS module 121 is not limited to the above-mentioned GPS, GALILEO, and GLONAS, it is okay to further include China's Beidou and other satellite positioning systems that may be added in the future.

In addition, as shown in FIG. 2, the location information module 120 sequentially lists the coordinate-based location information generated from the location information generator 122 and compares them with each other to detect location information where a singularity occurs. It may be configured in a form further including a detection unit 123.

And in this case, the location information generation unit 122 detects the location information where the singularity occurs from the detection unit 123. Among the satellite signals simultaneously received through the GNSS module 121, the reception sensitivity is the next (second) satellite. It may be configured to generate location information using a signal.

That is, since the satellite signal transmitted from the satellite is a signal of low power, if the fake signal is transmitted with a higher power than the satellite signal, a phenomenon in which the fake signal of high power is recognized instead of the satellite signal of low power may occur, and this may occur as a satellite signal. One of the disturbing phenomena is called spoofing.

Incorrect location information generated by such malicious spoofing causes serious problems in the establishment of firefighting operations in the command center and the rescue of firefighters, so it can be said to be a problem that must be resolved.

Therefore, as shown in FIG. 3, the detection unit 123 sequentially enumerates the coordinate-based location information generated from the location information generation unit 122 and compares them with each other to determine a location where a large error occurs with the previous location information. It is possible to detect information, and the location information generation unit 122 generates location information by using a satellite signal received with a next-order reception sensitivity for the purpose of excluding a fake signal received with high output, thereby creating confusion caused by a fake signal. occurrence can be prevented.

In other words, at the same time that the detection unit 123 detects the fake signal, the location information generation unit 122 generates location information using satellite signals received at the next highest reception sensitivity, thereby generating the command center by the fake signal. It is possible to prevent the occurrence of confusion in the etc.

However, since the generation of location information by fake signals is not completely limited, the location information generation unit 122 can continuously generate location information by fake signals in the background, and the detection unit 123 can generate location information by fake signals in the background. Position information by false signals can be sequentially listed and confirmed.

In addition, the point at which the location information of coordinates significantly different from the previous one starts to be sequentially listed is determined as the end of spoofing, and the location information using the satellite signal received with the highest reception sensitivity is replaced with the satellite signal received with the next reception sensitivity. It can be compared with the location information using , and when the two location information are identically generated, the location information generated using the satellite signal having the highest reception sensitivity can be transmitted to the outside.

In this way, the present invention configures the location information module 120 with the GNSS module 121, the location information generator 122, and the detector 123, so that reception of a specific satellite signal such as GPS is cut off or malicious signal jamming method It enables effective countermeasures in situations where spoofing, one of them, occurs.

In addition, as shown in FIG. 1, the radio 10 of the present invention is characterized in that a control unit 130 is provided for the purpose of performing an automatic transmission function of ambient temperature, an automatic transmission function of location information, and a rescue request function. to be

That is, as shown in FIG. 4 , the controller 130 controls temperature information and location information generated at the same time among temperature information generated by the temperature sensor 100 and location information generated by the location information module 120. At the same time, it is transmitted to the outside so that it can be used for the purpose of responding to forest fires.

At this time, the simultaneous transmission of temperature information and location information under the control of the control unit 130 preferably occurs at predetermined time intervals, but under specific conditions, such as when a sudden change in temperature is detected by the temperature sensor 100, Transmission may occur immediately, ignoring the set time interval.

In addition, the control unit 130 checks the tilt information generated by the tilt detection sensor 110 and generates an emergency signal when the tilt change does not occur for more than a preset time in a state in which a gradient equal to or greater than a predetermined gradient value is confirmed, It can be used for the purpose of rescue of firefighters facing an emergency by being transmitted to the outside at the same time along with the location information generated at the same time.

That is, the change in the tilt value of the radio 10 may occur at any time due to the nature of the environment in which the radio 10 of the present invention is used, but the change in tilt over a preset time in a state where the radio 10 is tilted more than a preset tilt value When it does not occur, it can be determined that a problem has occurred to the firefighters possessing the corresponding radio (10).

Therefore, as shown in FIG. 4, the control unit 130 generates an emergency signal under the above conditions and transmits it to the outside along with location information so that it can be used for rescue of firefighters facing an emergency situation. In addition, temperature information can be transmitted to the outside together so that it can be used for checking the field situation.

In addition, in the case of generating an emergency signal, the control unit 130 causes the maximum output noise to occur with vibration in the radio 10 of the present invention, thereby inducing the unconscious firefighters to recover consciousness. , noise and vibration can be stopped immediately after a change in the slope value occurs.

On the other hand, the simultaneous transmission of temperature information and location information generated by the radio 10 of the present invention and the simultaneous transmission of emergency signals and location information are carried out by one or more other radios 10 pre-grouped and the external management server 200. It is intended as a final destination, and may be transmitted directly without relaying according to the distance to the management server 200 or transmitted in a manner of being relayed one or more times by one or more radios 10 provided to other firefighters.

That is, the present invention is characterized in that it is configured to further include a relay function for extending the communication range, and through this configuration, it provides an effect of solving the communication vacuum in a forest fire site due to insufficient relay devices.

In addition, when the radio 10 of the present invention generates an emergency signal and transmits it to the outside along with location information, a unique identification number can be transmitted together, thereby preventing repeated relaying of the same emergency signal from the same radio 10. effect that does not occur.

That is, when the relay function for extending the communication range as described above is performed, the emergency signal and location information transmitted from a specific radio 10 to another radio 10 are returned from the radio 10 or another radio 10. A coming phenomenon may occur, and as a result, repeated relaying may occur in which the same emergency signal and location information are transmitted again.

Therefore, as a result, the same emergency signal and location information may be received several times at intervals from the external management server 200, which may cause confusion.

In order to prevent such a problem from occurring, the present invention may be configured to transmit a unique identification number together when generating and transmitting an emergency signal and location information, and all radios 10 receive the emergency signal and location information together. By checking the unique identification number, it is possible to prevent repeated relaying from occurring within a predetermined time.

In addition, the emergency signal and location information generated by the radio 10 of the present invention may be transmitted to one or more other radios 10 previously grouped, and in this case, only the radio 10 within the communicable range. It is desirable that transmission occur.

And in connection with the above configuration, the radio 10 of the present invention may be provided with an emergency button for a rescue request by the firefighter's own intention, and the firefighter himself presses the emergency button three or more times. By pressing continuously, emergency signals and location information can be simultaneously transmitted to the outside.

At this time, designating the number of pressing the emergency button as three times or more is to prevent simultaneous transmission of an emergency signal and location information due to a mistake by the firefighters themselves.

In addition, as shown in FIG. 1, the radio 10 of the present invention is provided with a wireless telegraph unit 140 that performs functions for radio telegraphy, including transmission of temperature information, emergency signals, and location information. to be

That is, the wireless telegraph unit 140 is configured for an automatic transmission function of ambient temperature, an automatic transmission function of location information, and an automatic rescue request function in addition to a radio telegraph function, which is an inherent function of the radio, and the control unit 130 Simultaneous transmission of temperature information and location information under control, or simultaneous transmission of emergency signals and location information.

In addition, the wireless telegraph unit 140 receives temperature information and location information or emergency signals and location information transmitted from other radios 10 and immediately transmits them to one or more other radios 10 located within a radio telegraph available distance. It is characterized in that it is configured to.

That is, as shown in FIG. 5, the radio 10 of the present invention is characterized in that it is configured to further include a relay function for extending the communication range, and according to this configuration, communication at a forest fire site by an insufficient relay device The effect of resolving gaps can occur.

Meanwhile, the management server 200 that receives temperature information, location information, emergency signals, and location information transmitted from the wireless telegraph unit 140 is a server device temporarily installed in the command center and includes a display device such as a monitor. By being configured in a form or installed together with a separate display device, various information according to the function of the present invention can be displayed.

That is, the management server 200 may use the received temperature information and location information to create or update current status information on the entire forest fire site and display it on a display device so that it can be used to establish a firefighting strategy.

In this case, the current status information may be displayed on a map in various ways in association with map information of an area where a forest fire has occurred, but restrictions do not necessarily occur in this form.

In addition, the management server 200 can generate emergency information using the received emergency signal and location information and display it on a display device so that it can be used for rescue of firefighters facing an emergency situation.

That is, personnel located in the command center identify the location of the accident by checking the emergency information displayed on the display device, and transmit the entire radio to provide rescue to other firefighters located near the firefighter facing the emergency situation. information can be delivered, and other necessary measures can be taken.

At this time, the management server 200 can prevent the creation of a plurality of emergency information by the same emergency signal by checking the unique identification number received together with the emergency signal and location information.

In addition, the management server 200 tracks and monitors the location of firefighters in the mountains using location information received together with temperature information, generates emergency information even when a firefighter leaving the group is identified, and displays the information on the display device. By making it visible, a response from the command center can occur.

That is, the management server 200 checks the location of each firefighting crew member located in the mountain, and generates emergency information when a firefighting crew member is separated from other firefighting crew members by a predetermined distance or more in a state where one firefighting crew member is located alone. It can be displayed on the display device, and personnel located in the command center can identify the location where the accident occurred by checking the emergency information displayed on the display device, and can solve the problem by transmitting the entire radio.
