Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and the contents described in the accompanying drawings, but the present invention is not limited or limited by the embodiments.

Figure 1 is an example showing the relationship between communication and sensing. The present invention seeks to propose a new technology based on relationships such as similarities between communication and sensing, and will specifically explain elements that can be invented by expanding to waves, purposes, and objects related to the relationship.

Figure 2 is an example showing the meaning of waves, and communication and sensing technologies have similarities in utilizing wave signals. A wave is a phenomenon in which a change in the physical state that occurs at one point in space gradually spreads around, meaning signals such as sound waves, light, and radio waves. Light and radio waves are commonly referred to as electromagnetic waves. Sound waves must exist in a medium such as air.

Conventionally, wave signals can be used to detect a surveillance target and can be used for communication of a communication target. Sound waves and infrared waves can be mainly used for communication and detection in the short-range area, and radio waves can be mainly used for communication and detection in the long-distance area.

In addition to sound waves, infrared waves, and radio waves, wave signals may be visible light, x-rays, and gamma rays, and may be various signals that can be communicated or detected, but are not limited to these.

Figure 3 shows an example in which communication and sensing are utilized. For example, sound waves and infrared waves are used to detect intrusions or movements in a short-range area, or are used for communication to warn intruders. For another example, radio waves are used for data communication in remote areas or to detect the location of a terminal by determining the strength of signals between base stations.

In addition, sound waves can be used for communication purposes such as DTMF (Dual Tone Multiple Frequency) or as situational radio waves, and can be used as control inputs for devices. Infrared rays can also be modulated and used for communication purposes or status broadcasting, and can be used as control inputs for devices such as remote controls.

Figure 4 is a block diagram showing a disaster safety operation system according to an embodiment of the present invention. The technology for both communication and detection is a technology suitable for the next-generation disaster safety communication network and 6G, and is a technology capable of various application services. For example, the disaster safety communication network provides various application services such as artificial intelligence (AI) decision-making, use of drones at disaster sites, and disaster monitoring based on sensor data.

The disaster safety operation system 10 includes a field terminal 100, an integrated operation server 200, and a public server 300. The field terminal 100 can be deployed to a site such as a disaster to sense the environment of the site, and provide the sensed information to the integrated operation server 200 through a communication network.

The integrated operation server 200 can control the operation of the field terminal 100 using sensed information or public information provided by the public server 300. Public information is information about public facilities related to the site. For example, if a water facility exists on site, public information includes information about the status or location of the water facility.

Figure 5 is an example of dividing field terminals, and field terminals 100 are divided into mobile terminals and fixed terminals. Mobile terminals are typically divided into smartphones and autonomous driving terminals. Self-driving terminals can be diverse, including drones, cars, robots, and ships.

A fixed terminal is a non-mobile terminal and may be a terminal installed in a home or factory, or may be a smart pole installed with a repeater to expand the coverage of wireless communication.

More specifically, a smartphone user may be a user experiencing a disaster situation or a user controlling a disaster situation. An autonomous driving terminal may be a terminal that monitors disaster situations or performs rescue activities. The fixed terminal may be a terminal located at the disaster site and monitoring the disaster situation, or it may be a terminal located a predetermined distance away from the disaster site and relaying communication with a smartphone or self-driving terminal.

In this way, the purpose of use of field terminals for both communication and detection may vary depending on the form or structure, and the purpose of use using sensing information may also vary. Considering this, various scenarios are constructed and the transmission/reception structure and integrated circuit are designed. must be reflected.

The present invention has expanded the keywords according to the relationship between communication and sensing as shown in Figure 1 to Figures 2 and 4, and the core technology of the present invention will be described starting with Figure 6, which will be described later.

Figure 6 is a block diagram showing a field terminal according to an embodiment of the present invention. The field terminal 100 includes a CS unit 110 and a control unit 190. The CS unit 110 is a name that combines communication and sensing.

The CS unit 110 includes a transmitter 111 and a receiver 112. The transmitter 111 is equipped with a plurality of transmission functions for each transmission path for the purpose of communication and detection. The receiving unit 112 is equipped with a plurality of receiving functions for each receiving channel.

Figure 7 is a block diagram showing the transmitter side of Figure 6 in detail, and the present invention can perform single signal communication and sensing operations together. The transmitter 111 may include a wave generator 111-1, a power control element 111-2, and a path control element 111-3. The wave generator (111-1) generates a wave signal, the power control element (111-2) controls the power supply for wave signal generation, and the path control element (111-3) controls the transmission path of the wave signal. And the control unit 190 controls the transmitter using the control information.

Wave signals may have different power or bandwidth for detection in the short-range and long-distance areas, and may have different power or bandwidth for communication in the short-range and long-distance areas. .

Control information is information for allocating power or bandwidth for each transmission path for communication purposes and detection purposes in response to the short-distance area and the long-distance area. The field terminal 100 may further include a storage unit 120 that stores control information.

A single wave signal may be transmitted through a specific single path through the path control element 111-3, or may be distributed and transmitted through a plurality of paths. At this time, the power control element 111-2 controls power supply because the amount of power used may vary depending on the use of each path of a single wave signal.

The control information may include switching values by which the power control element 111-2 and the path control element 111-2 are driven according to the use of each path for a single wave signal.

The present invention can provide the power, bandwidth, and transmission path of a transmission signal appropriate for each near area and long distance area, each communication state in the long distance area, and each communication purpose and detection purpose.

In the present invention, since the power, bandwidth, and transmission path of the transmission signal may be different for each of the above-mentioned conditions, the power control element 111-2 and the path control element (111-2) are used to control the power, bandwidth, and transmission path of the transmission signal together. 111-3) organic control is necessary. The present invention can provide both communication and detection functions for each condition by controlling the power, bandwidth, and transmission path of the transmission signal.

The wave generator 111-1 may generate three types of signals, including different types of signals or radio waves, such as infrared waves and sound waves, and the control information may include information for controlling the generation of different types or three types of signals. there is.

The receiving unit 111 can detect the state of a short-distance area or generate sensing information by detecting a wave signal from the transmitting unit, and the control unit 190 can allocate the power or bandwidth of the set transmission path with reference to the sensing information. . The sensed information may be information related to absorptive fading.

In 6G, it is decided to utilize ultra-high frequency bandwidth such as terahertz. However, ultra-high frequency bandwidth has the disadvantage of being vulnerable to absorptive fading, so a method to solve this problem is needed.

Absorptive fading is fading that occurs when radio waves are absorbed (attenuated) as they pass through the ionosphere. More specifically, absorptive fading means that when radio waves pass through or are reflected through the ionosphere, some of their force is absorbed and attenuated due to collisions with electrons and air molecules, and can be caused by atmospheric phenomena. In the past, as a countermeasure against absorptive fading, AGC was used in the receiver to keep the reception output constant.

The present invention is a transmission technology that detects elements related to absorptive fading and allocates the power or bandwidth of the transmission signal based on the detected information, and is intended to contribute to 6G standardization.

The present invention can detect such atmospheric phenomenon and generate sensed information, calculate the corresponding power or bandwidth with the value of the sensed information, and allocate power or bandwidth with the calculated information to respond to absorptive fading. It can provide robust communication.

Since the present invention can be used as sensing information instead of channel information (CSI: Channel State Information) between terminals, procedures for sharing channel information may be unnecessary, and payload for sharing channel information is wasted. can be reduced. For reference, preferably, the field terminal 100 here may be a base station or repeater that provides or expands communication coverage rather than a smartphone.

FIG. 8 is a block diagram illustrating the receiver of FIG. 6 in detail. The receiver 112 may include a sensor-type receiver 112-1 and a detection-type receiver 112-2. The sensor-type receiver 112-1 detects the state of a nearby area and generates a first detection value. The detection type receiver 112-2 detects a wave signal from the communication target or the transmitter and generates a second detection value.

In the present invention, the receiver 112 is divided into a sensor-type receiver 112-1 and a detection-type receiver 112-2, but the principle of detecting a specific signal and converting it into a detection value is the same. However, the sensor-type receiver 112-1 generates the first detection value by directly detecting the monitored object or environment, and the detection-type receiver 112-2 detects a wave signal in contact with the monitored object or environment. This generates a second detection value.

The sensor-type receiver 112-1 can detect conditions in a short-distance area caused by natural phenomena, and can typically detect light, heat, temperature, and humidity. The sensor-type receiver 112-1 can detect phenomena occurring in communication targets such as people or objects.

The detection type receiver 112-2 can generate a second detection value according to a change in the channel as the wave signal from the transmitter 111 is transmitted through the channel. The wave signal can be detected in the detection type receiver 112-2 through channels such as reflection, diffraction, attenuation, delay, absorption, frequency, or noise characteristics.

FIG. 9 is a block diagram illustrating the detection type receiver of FIG. 8 in detail. The detection type receiver 112-2 includes a first detection type receiver 112-2a and a second detection type receiver 112-2b. can do. The path control element 111-3 can separate a single wave signal into two first transmission paths and a second transmission path, and the first detection type receiver 112-2a can detect the wave signal that has passed through the first transmission path. The signal can be detected, and the second detection type receiver (112-2b) can detect the wave signal that has passed through the second transmission path.

For example, in gas detection, the sensor-type receiver 112-1 absorbs gas particles on a semiconductor, measures the adsorbed amount as resistance, and measures gas concentration based on this. The infrared signal of the transmitter 111 passes through a first channel where gas is present and a second channel for detecting intrusion by the path control element 111-3, and the first detection type receiver 112-2a The gas concentration is measured by detecting the infrared signal passing through the first channel, and the second detection type receiver (112-2b) detects intrusion using the infrared signal passing through the second channel.

When the present invention is used for sensing purposes in a short-range area, the transmission path can be controlled by distributing a single wave signal generated by the wave generator 111-1 to the first channel and the second channel in the short-range area. For example, the path control element 111-3 can distribute a single infrared signal into two channels for the purpose of detecting gas concentration and movement. At this time, to detect the gas concentration, an infrared signal of a set wavelength suitable for the gas characteristics can be used, and to detect movement, it can be used regardless of the wavelength band, so the present invention uses the path control element 111-3. A single wave signal can be used together for the purpose of detecting gas concentration and movement.

The present invention controls the path of the transmitter 111 by the path control element 111-3, provides distribution of wave signals by controlling the path of the transmitter 111, and provides distribution of wave signals on the transmitting side. Thus, multiple detection purposes can be achieved.

The control unit 190 processes the first sensed value or the second sensed value to generate sensed information, and determines a transmission path or a receiving path using a scenario for each purpose of use of the sensed information.

The purpose of use of the field terminal 100 for both communication and sensing may vary depending on its form or structure, and the technology for utilizing the sensing information may also be completely different. The present invention takes all of these points into consideration and builds a scenario for each purpose of use of the sensed information. Using the scenario, the transmission path or the reception path can be controlled, and the allocation of power or bandwidth can be controlled as described above. .

Figure 10 is a block diagram showing a field terminal according to another embodiment of the present invention. In addition to the above, the field terminal 100 can be used to change the route of autonomous driving using a scenario.

The transmitter 111 can transmit the sensing information generated by the receiver 112 to a long-distance communication target, and the control unit 190 can perform free driving using the integrated path information received by the receiver 112.

Integrated route information may include at least one of GPS-based route information, route information in GPS shadow areas, location information of long-distance communication targets, and route change information, and the route change information is generated based on current location information and sensed information. It may be information that has been provided.

GPS-based route information is information generally provided with GPS-based coordinates, and route information for GPS shadow areas is route information for shaded areas where GPS communication is difficult and may include location information of previously stored features related to GPS shadow areas. You can. Additionally, the route information in the GPS shadow area may be route information obtained by driving another field terminal. Location information of a long-distance communication target is literally information about the coordinates where the long-distance communication target is located.

The present invention can generate sensed information and transmit it to a long-distance communication target, and can receive route change information whose path has been changed in response to the sensed information from the long-distance communication target. For example, the sensed information may include information that detects an unexpected obstacle such as a fire, information that detects meteorological factors, or information that is sensed in combination.

The long-distance communication target of the present invention is the integrated operation server 200, which can regenerate integrated route information to reflect additional conditions such as sensed information in addition to the conditions regarding the route with or without GPS and provide it to the field terminal 100.

Since the detection information may include information about conditions in which voluntary lane changes in autonomous driving are difficult, and may be information to be applied together to route-specific conditions of GPS and non-GPS, the present invention provides the field terminal 100 with a voluntary or It may be difficult to change the route on the fly, and to solve this problem, integrated route information can be generated through analysis including sensing information from a long-distance communication target.

Previously, in addition to the ground, coverage of specific areas such as deserts and seas was expanded using the Stratospheric Aircraft Communication System (HAPS) or GPS.

The present invention can automatically set an autonomous driving route according to GPS and non-GPS situations. Non-GPS refers to areas where it is difficult to receive GPS signals, such as tunnels or underground, and the present invention can acquire coordinate information of these areas in advance and reflect them in the autonomous driving route.

The present invention is a technology that detects such situations and reflects the sensed information in the autonomous driving path because a disaster or abnormal sign may occur on the autonomous driving route and a route change may occur. This technology can be included in a scenario.

In the present invention, a plurality of receiving units 112 for detection, such as a sensor-type receiving unit 112-1 and a detection-type receiving unit 112-2, are configured to ensure diversity of sensed information. In addition, the present invention allows multiple purposes of use of the sensed information due to the diversity of the sensed information, and can be constructed in the form of a scenario. Additionally, the present invention can be applied together with specific sensed information to two or more scenarios. For example, the present invention can be applied together in two or more scenarios, such as determining the purpose of weather detection information whether to communicate or sense it, determining the route, allocating power or bandwidth, or changing the route of autonomous driving. Accordingly, the present invention can construct scenarios for each purpose of use for both communication and detection in order to achieve the above-described functions and effects.

In the present invention, by constructing a scenario for each purpose of use of sensed information, a specific path can be determined among multiple paths and the determined specific path can be controlled.

The transmitter 111 may be equipped with a function of generating a first transmission signal for detection purposes, a second transmission signal for communication with a short-distance communication target, and a third transmission signal for communication with a long-distance communication target.

The receiver receives a 1-1 reception signal for receiving the first transmission signal, a 1-2 reception signal for detecting the status of a short-distance area, a 2nd reception signal for communication with a short-distance communication target, and a 1-2 reception signal for communication with a short-distance communication target. A function for generating a third reception signal for communication may be provided.

The control unit 190 can perform the purpose of communication and detection by controlling the activation timing of at least one of a plurality of transmission and reception functions.

The short-range communication target refers to a target where the field terminal 100 is located in a short-distance area, and the long-distance communication target refers to a target located in a remote area. Communication in the short-range area may have narrower coverage than communication in the long-distance area.

Communication with a short-distance communication target is possible when the field terminal 100 is located in a short-distance area, but communication may be difficult if the field terminal 100 is located in a long-distance area. On the other hand, communication with a long-distance communication target is possible no matter where the field terminal 100 is located in any area, such as a short-distance area or a long-distance area.

The control unit 190 can generate sensed information by processing the 1-1st received signal and the 1-2nd received signal, and the transmitter 111 can generate a third transmitted signal by modulating the sensed information. Can receive a third reception signal from a long-distance communication target that receives the third transmission signal, and the control unit 190 can update control information by processing the third reception signal. For example, the updated control information is route change information related to autonomous driving or information for determining whether to generate a second transmission signal.

The control unit 190 can generate sensing information by processing the 1-1 received signal and the 1-2 received signal, and determine whether an event has occurred by comparing the sensed information with pre-stored reference information. When this occurs, a second transmission signal for controlling the short-distance communication target can be generated through the transmitter 111, and a third transmission signal can be generated including action information according to the communication of the short-distance communication target.

The short-range communication target may include an intrusion target and a field device that receives the first transmission signal, and when an event occurs, the control unit 190 can directly notify the intrusion target of an alarm through the transmitter 111 and the field device. You can indirectly notify an alarm by controlling .

For example, the present invention can generate detection information about whether there is an intrusion, generate a second transmission signal to notify the intrusion target or field device of an alarm, and provide a third transmission signal regarding measures to be taken to the remote communication target. there is. Here, the field device may be a device that can provide a warning to the intruder, and the long-distance communication target may be an object for disseminating the situation. The present invention has the remarkable effect of preventing damage caused by an intruder by providing a warning to the intruder, and disseminating the situation to a long-distance communication target.

When located in a wireless communication shadow area, the control unit 190 can generate a second transmission signal indicating its location through the transmitter 111, and when located in a GPS shadow area while within wireless communication coverage, it can measure its own location. A third transmission signal containing permission information authorizing can be generated.

For example, if danger or distress occurs in a personal situation, the user can broadcast his or her situation through the field terminal 100. At this time, if the field terminal 100 is located in a wireless communication shadow area, it can generate a second transmission signal so that nearby terminals or people can notice it, and if it is located in the wireless communication coverage area and in a GPS sound area, its location can be determined. A third transmission signal allowing measurement can be generated. Accordingly, the present invention has the function of disseminating the user's situation according to each communication situation, and through this, has the effect of providing a safe structure for the user.

The second transmission signal can be divided into audible and non-audible. The control unit 190 may determine whether to generate a second transmission signal by selecting at least one of audible and inaudible based on set reference information for announcing one's location or allowing location measurement.

A smartphone is a terminal that is usually owned by everyone and used to detect or spread the word when danger or distress occurs in a personal situation.

The present invention applies a technology (Sensing for Grant Free) that allows the smartphone to measure its own location when it is located in wireless communication coverage, and when it is located in a shaded area, a technology that announces its location through an audible or inaudible signal is applied. do. For example, an audible signal generates a signal that can be heard by people nearby, and an inaudible signal is used for detection purposes in terminals for disaster relief.

The CS unit 110 may utilize some of the components from short-range sensing to short-range communication, and from long-distance region communication to long-distance sensing. For example, the CS unit 110 utilizes both communication and detection for each path through the path control element 111-3 on the transmitter side or the receiver side.
