Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a system for detecting a dangerous situation of a motorcycle using a sensor and a method for transmitting an emergency rescue signal using the sensor,

The present invention relates to a system for detecting a dangerous situation of a motorcycle using a sensor and a method for transmitting an emergency rescue signal using the same. More particularly, the present invention relates to a system for detecting a dangerous situation of a motorcycle, And more particularly, to a method for quickly transmitting information on a mobile terminal.

In the case of a motorcycle-like motorcycle, the degree of injury to the driver is much greater than in the case of an accident. According to the result of traffic accident analysis at the road traffic corporation, the mortality rate of motorcycle accidents is 2.7 times that of passenger car accident. Such a motorcycle-like two-wheeled vehicle has no body to absorb shocks in the event of an accident and has a higher chance of overturning, so the occupant's damage is much larger than that of a passenger car.

In the case of a two-wheeled vehicle, accidents occurred in rare places may be delayed due to lack of witnesses (for example, 119 reports). In the case of a traffic accident, early emergency measures are very important in case of an accident. Delay in the report of the occurrence of the accident may delay the emergency action of the driver, which may result in injury to the driver.

Also, in the event of an accident, the driver or passenger can spread the dangerous situation, or surrounding people around him can spread the dangerous situation. On the other hand, there may be cases where the driver, passenger or neighbor can not be able to spread the danger. In such a case, secondary damage may occur.

Patent Document 1 discloses a vehicle accident automatic notification device. The vehicle accident automatic notification device of Patent Document 1 receives an accident occurrence event generated from an airbag control unit and a battery removal signal of a removal signal generation unit that detects main battery removal through input and output ports, And an accident notification signal output from a telematics control unit for receiving an accident occurrence event from an airbag control unit for operating the airbag, and accident-related information such as an accident occurrence location and an occurrence time. The automobile accident automatic notification device of the 'Patent Document 1' automatically notifies that an accident has occurred by the above technical feature, and can request an emergency rescue support.

However, since the automatic vehicle notification system of Patent Document 1 has the feature of being applied to an automobile as a four-wheeled vehicle, it is difficult to apply it to a two-wheeled vehicle such as a motorcycle. In addition, the automobile accident notification device of the 'Patent Document 1' is merely a notification of a vehicle accident, which is problematic in that its usability is poor.

1 is a schematic block diagram of a system for detecting a dangerous situation of a motorcycle using a sensor according to an embodiment of the present invention. Referring to FIG. 1, a dangerous situation detection system for a two-wheeled vehicle using sensors according to the present invention is installed in a two-wheeled vehicle. The system detects the acceleration and the inclination of the two-wheeled vehicle to determine a situation of the two- Sensing device (100); A user terminal (200) which receives the notification information from the situation sensing device and transmits the notification information according to a user's input; And a management server 300 receiving the notification information from the user terminal 200 and transmitting the notification information to the emergency rescue organization.

The situation detecting device 100 is a component installed on the two-wheeled motor vehicle to detect the acceleration and the inclination of the two-wheeled vehicle to determine the state of the two-wheeled vehicle. FIG. 2 is a block diagram of a situation sensing apparatus 100 according to an embodiment of the present invention. Referring to FIG. 2, the sensing apparatus 100 includes a sensing unit 110 for sensing an acceleration and a tilt of a motorcycle ); A situation determining unit 120 for determining the state of the motorcycle by referring to a change in acceleration and a change in slope; And a communication unit 130 for transmitting notification information according to a determination result.

In the case of a two-wheeled vehicle, the slope of the ground is not large in both the case of running or the case of being stopped / stopped. Considering this point, if the change of the slope of the two-wheeled vehicle is sudden, it can be considered that the two-wheeled vehicle has fallen and that the two-wheeled vehicle is in a dangerous situation or an accident situation. For example, the situation determination unit 120 determines that the two-wheeled vehicle has caused an accident as the inclination of the two-wheeled vehicle with respect to the ground becomes smaller (the more the two-wheeled vehicle lies on the ground) .

The notification information may include an accident notification and an accident notification. The accident notification indicates a notification that the accident has not occurred on the motorcycle. The accident notification indicates a notification that the accident occurred on the motorcycle.

In the case of the accident notification, the situation sensing apparatus 100 can determine the state of the motorcycle (whether or not an accident has occurred) by referring to the newly detected acceleration and slope. That is, it is determined that the accident occurrence state of the two-wheeled vehicle determined based on the previously detected acceleration and tilt is an error, and the situation sensing apparatus 100 continuously judges the state of the two-wheeled vehicle with reference to only the acceleration and inclination detected subsequently .

On the other hand, in case of an accident notification, the situation detecting apparatus 100 may collect incident related information of the two-wheeled vehicle and transmit the collected incident related information. For example, the situation sensing apparatus 100 may collect and transmit accident-related information such as the driving state, the position, the speed at the time of an accident, and the damage state of the two-wheeled vehicle.

After transmitting the notification information or transmitting the incident-related information, the situation sensing apparatus 100 may output an alarm. For example, the situation sensing apparatus 100 may output a warning sound to notify a surrounding person that an accident has occurred. As another example, the situation sensing apparatus 100 may be configured to control the emergency light of the motorcycle, and the situation sensing apparatus 100 may turn on the emergency light of the motorcycle to notify the surrounding persons that an accident has occurred have. The situation sensing apparatus 100 may simultaneously operate an alarm sound and an emergency light as necessary.

The user terminal 200 receives the notification information from the situation sensing apparatus 100 and transmits the notification information according to whether the user inputs the notification information. Such a user terminal 200 may be, for example, a smartphone, a tablet personal computer, a mobile phone, a video phone, a desktop personal computer, a laptop personal computer, A netbook computer, a personal digital assistant (PDA), a portable multimedia player (PMP), a wearable device (e.g., smart glasses, head-mounted-device And a smart watch).

The user terminal 200 receives notification information from the situation sensing device 100 installed on the motorcycle and transmits notification information to the management server 300 or the contact information stored in the user terminal 200 according to whether the received notification information is inputted by the user To the contact information. When the emergency contact is stored in the user terminal 200, the user terminal 200 receives the notification information, and then transmits the notification information to the stored emergency contact information Can be transmitted. These emergency contacts can be family, friends, etc., and can be 119 (fire station), hospital, police station, insurance company if necessary. Also, the notification information transmitted from the user terminal 200 may have the form of a text message.

The user terminal 200 can transmit the unexpected notification when there is user input within a preset time after the notification information is received, The user terminal 200 may transmit an accident notification.

Also, the notification information indicates that an accident has occurred in the two-wheeled vehicle due to the situation sensing apparatus 100. Even if notification information is generated, the accident may not have occurred in the two-wheeled vehicle. If an accident does not occur, the user (driver) can input that the accident has not occurred in the user terminal 200 after receiving the notification information through the user terminal 200. On the other hand, when an accident occurs in the two-wheeled vehicle, the user may not be able to input anything into his or her own user terminal 200. If no information is input to the user terminal 200 within a predetermined time, the user terminal 200 transmits notification information indicating that an accident has actually occurred to the user.

The management server 300 is a component that receives the notification information from the user terminal 200 and transmits the notification information to the emergency rescue organization. That is, the management server 300 plays a role of receiving and storing information from the user terminal 200. In particular, the management server 300 can receive the notification information and transmit the notification information to the emergency rescue organization.

The management server 300 may manage the communication between the situation sensing apparatus 100 and the user terminal 200. For example, the management server 300 may include a situation sensing apparatus 100 mounted on the motorcycle, And the user terminal 200, as shown in FIG. The information transmitted by the situation sensing apparatus 100 may be transmitted to the user terminal 200 through the management server 300 and the information transmitted by the user terminal 200 may be transmitted through the status server 300 100).

In a dangerous situation detection system for a motorcycle using a sensor according to an embodiment of the present invention, a GPS module may be installed in the situation sensing apparatus 100 or the user terminal 200. The GPS module can recognize the current position of the two-wheeled vehicle, and at this time, the management server 300 can transmit the notification information to a vehicle approaching the current position of the two-wheeled vehicle identified by the GPS module.

For example, when the two-wheeled vehicle in which the situation sensing apparatus 100 is installed is in a dangerous situation (an accident occurrence situation), the situation sensing apparatus 100 senses it, and notification information therefrom is transmitted to the management server 300. At this time, the management server 300 may transmit the notification information to the vehicles approaching the current position of the motorcycle where the accident occurred. This notification information transmission transmits notification information to a base station or AP (access point) closest to the present position of the accident motorcycle, and the base station or the AP that receives the notification information transmits notification information to a plurality of unspecified terminals . It is possible to prevent the secondary accident from occurring by transmitting the notification information to the terminal around the current position of the motorcycle in which the above-mentioned accident occurred.

2 is a configuration diagram of a situation sensing apparatus according to an embodiment of the present invention. Referring to FIG. 2, a situation sensing apparatus according to an embodiment of the present invention includes a sensing unit 110 for sensing an acceleration and a tilt of a motorcycle; A situation determining unit 120 for determining the state of the motorcycle by referring to a change in acceleration and a change in slope; And a communication unit 130 for transmitting notification information according to a determination result. And may further include an information collecting unit 140, a storage unit 150, and a control unit 160 as necessary.

Referring to FIG. 3, the sensing unit 110 is attached to the motorcycle and senses various states of the motorcycle. For example, The controller 110 may include an acceleration sensor 111 and a tilt sensor 112 for sensing acceleration and tilt of the motorcycle. And may include a gyro sensor 113 as needed.

The acceleration sensor 111 senses the acceleration of the two-wheeled vehicle. In the present invention, the acceleration sensor 111 preferably senses the acceleration of the two-wheeled vehicle in the traveling direction. Therefore, the acceleration sensor 111 can sense the acceleration generated toward the front and rear of the two-wheeler.

The inclination sensor 112 senses the inclination of the two-wheeled vehicle relative to the ground. Particularly, in the present invention, the inclination of the two-wheeled vehicle can be changed with respect to the ground while the vehicle is running. Can be detected.

The situation determining unit 120 determines that the state of the two-wheeled vehicle is in a stopped state when there is no change in the accumulated acceleration, applies the change in the acceleration to the accumulated time, and when the speed is determined to be 0, It is determined that the state of the two-wheeled vehicle is a constant-speed movement state when it is determined that the state of the two-wheeled vehicle is a constant-speed movement state and the acceleration is determined to be non-zero by applying the change of the acceleration to the cumulative time, It is determined that the speed is not 0 by applying the change in the cumulative time, and it can be determined that the situation of the motorcycle is in the acceleration movement state when the current acceleration is not 0.

In the present invention, the running state of the two-wheeled vehicle may include at least one of a pre-movement stop state, a post-movement stop state, a constant speed movement state, and an accelerated movement state. The stopping state before movement indicates the state where the two-wheeled vehicle has stopped before moving. For example, the state immediately after startup may be included in the pre-movement stop state. The stop state after the movement indicates the state where the two-wheeler is stopped after the movement. For example, a state in which the two-wheeled vehicle traveling at a constant speed is stopped for signal waiting may be included in the stop state after the movement. The constant speed movement state indicates a state in which the two-wheeler is moving at a constant speed. Here, the speed is not zero. The accelerated movement state indicates a state in which the speed of the two-wheeler increases or decreases to a certain magnitude.

Also, the situation determination unit 120 can determine the running state of the two-wheeled vehicle by referring to the currently detected acceleration change and the preset acceleration pattern. The running state and the acceleration pattern of the two-wheeled vehicle may be provided in the form of a table.

The two-wheeler driving state table 400 may include a two-wheeler driving state field 410 and an acceleration changing field 420 as shown in FIG. The two-wheeler's running state field 410 may include the running state of the two-wheeler. Specifically, the stationary state and the moving state may be included in the two-wheeled vehicle running state field 410. Here, the stop state includes a stop state before movement and a stop state after movement, and the movement state may include a constant movement state and an accelerated movement state. The acceleration change field 420 may be included in the acceleration change pattern for each running state. The situation determination unit 120 may sense the acceleration sensed by the acceleration sensor 111 for a predetermined period of time and check the change. The situation determining unit 120 may compare the detected acceleration change with the acceleration change pattern included in the acceleration change field 420 to determine the running state of the two-wheeled vehicle.

Here, the predetermined time used for determining the acceleration change may be a predetermined one. The situation determination unit 120 can check the acceleration change by a predetermined time interval and determine the running state of the two-wheeled vehicle according to the result. In order to confirm the elapsed time, the situation determination unit 120 may use a timer.

The situation determining unit 120 can determine that the running state of the two-wheeled vehicle is in the stopping state before moving when there is no change in the accumulated acceleration. For example, since there is no change in the accumulated acceleration immediately after the start, the situation determination unit 120 can determine that the running state of the two-wheeled vehicle is the stopping state before the movement.

The situation determining unit 120 may determine that the driving state of the two-wheeled vehicle is in a stop state after the movement when it is determined that the speed is 0 by applying the change in acceleration to the cumulative time. For example, the situation determining unit 120 may compare the accumulation amount of the positive acceleration with the accumulation amount of the negative acceleration in the state where the positive acceleration continues for a predetermined time and the negative acceleration continues for another predetermined period of time . Thus, when the cumulative amount of the positive acceleration and the cumulative amount of the negative acceleration are equal to each other, the situation determination unit 120 determines that the vehicle speed is zero and determines that the running state of the vehicle is in a stopped state after the movement.

The situation determining unit 120 determines that the speed is not zero by applying a change in acceleration to the cumulative time and can determine that the running state of the vehicle is a constant speed moving state when the current acceleration is zero. For example, when the cumulative amount of the positive acceleration and the cumulative amount of the negative acceleration are different from each other and the current acceleration is 0, the situation determination unit 120 can determine that the running state of the two-wheeled vehicle is the constant-speed moving state.

The situation determination unit 120 may determine that the speed is not zero by applying a change in acceleration to the accumulation time and may determine that the driving state of the two-wheeled vehicle is in the accelerated traveling state when the current acceleration is not zero. For example, when the cumulative amount of the positive acceleration and the cumulative amount of the negative acceleration are different from each other and the current acceleration is not 0, the situation determination unit 120 can determine that the running state of the vehicle is in the constant speed movement state .

Also, the situation determination unit 120 can determine the accident state of the two-wheeled vehicle by referring to the tilt detected by the tilt sensor 111. [ Specifically, the situation determining unit 120 may determine that the accident has occurred according to whether or not the inclination detected by the inclination sensor 111 is included in a preset threshold slope range.

The situation determination unit 120 may determine that the situation of the two-wheeled vehicle is an accident occurrence state when the cumulative time when the inclination of the vehicle is out of the critical slope range exceeds a predetermined critical duration. Here, the cumulative time used to determine the slope change may be predetermined. The situation determination unit 120 can check the slope change by a predetermined cumulative interval and determine the accident state of the vehicle according to the result. The status determiner 120 may use the timer 260 to confirm the accumulated time.

The critical slope range and critical duration can be implemented in the form of a table, which is illustrated in FIG. 5, the two-wheeled motor vehicle inclination table 500 includes a two-wheeler type field 510, an identification code field 520, a slope minimum value field 530, a slope maximum value field 540, and a critical duration field 550 .

The two-wheeler type field 510 may specify the type of the two-wheeler. The allowable inclination of the two-wheeled vehicle may vary depending on the displacement amount, the shape and the purpose of use. The two-wheeler type field 510 may include the type of the two-wheeler according to the allowable inclination.

In the identification code field 520, a unique identification code corresponding to the type of the specific motorcycle can be specified. It becomes possible to confirm the type of the two-wheeler only with the identification code.

The slope minimum value field 530 specifies the minimum angle of the allowed motorcycle for the ground and the slope maximum value field 540 may specify the maximum angle of the vehicle allowed for the ground.

As shown in Fig. 6, the two-wheeled vehicle B can be tilted at a predetermined angle with respect to the ground F. At this time, the critical slope range of the two-wheeled vehicle B can be determined with respect to one side F of the two-wheeled vehicle B. Here, a represents a slope minimum value and b represents a slope maximum value. In other words, the two-wheeled vehicle B can safely operate within the range of a to b.

Referring again to FIG. 5, the criterion duration time field 550 may specify a criterion time for judging an accident state of the two-wheeler, that is, a critical duration. When the slope of the two-wheeled vehicle exceeds the critical slope range for a predetermined time, the situation determination unit 120 may determine that an accident has occurred in the vehicle. Since it is possible to run the motorcycle at an inclined state with respect to the ground, it may be undesirable to simply judge whether an accident has occurred due to the fact that the inclination of the motorcycle is out of the critical slope range. Accordingly, the situation determination unit 120 determines that an accident has occurred in the two-wheel vehicle only when the inclination of the vehicle is out of the critical slope range for a predetermined period of time. Here, the predetermined time corresponds to the critical duration.

The critical slope range and critical duration may vary depending on the type of the motorcycle.

The situation determination unit 120 can check the type of the two-wheel vehicle provided with the situation sensing apparatus 100, and can determine the accident state of the two-wheel vehicle using the critical slope range and the critical duration corresponding to the type of the two-

According to an embodiment of the present invention, the situation determination unit 120 may determine that the accident state of the motorcycle is in an accident occurrence state when the detected acceleration exceeds the preset critical acceleration. For example, when the motorcycle suddenly stops suddenly or starts suddenly, this can be regarded as a result of a collision, and the situation determination unit 120 can determine the accident state of the vehicle using the acceleration.

Once it is determined that the state of the two-wheeled vehicle is an accident occurrence state, the situation determination unit 120 may not judge the accident state of the vehicle with respect to the acceleration and slope to be detected subsequently. Meanwhile, when it is determined that the accident state of the vehicle is an accident occurrence state, the communication unit 130 transmits an accident detection notification. When the accident notification is received in response to the transmission of the accident detection notification, the situation determination unit 120 The accident state of the vehicle can be determined with reference to the newly detected acceleration and tilt.

The unexpected accident notification indicates that the accident occurrence state determined by the situation determination unit 120 is due to an error. Accordingly, the situation determination unit 120 can remove the previously detected acceleration and the accidental state caused by the inclination, and determine the accident state of the vehicle using the newly sensed acceleration and slope.

The communication unit 130 plays a role of transmitting notification information according to the determination result of the situation determination unit 120. For example, when it is determined by the situation determination unit 120 that the state of the two-wheeled vehicle is an accident occurrence state, the communication unit 130 can transmit notification information.

The communication unit 130 can communicate with the management server 300. However, if the management server 300 is not provided or communication with the management server 300 is not available, the communication unit 130 communicates with the user terminal 200, Information can be transmitted and received.

When communicating with the management server 300, the communication unit 130 performs LoRa (Long Range) communication and can transmit and receive information in the form of a message according to the MQTT (Messaging Queuing Telemetry Transport) protocol.

LoRa communication can be used with low power and long distance communication is possible. In particular, it is possible to connect a plurality of sensor nodes. Various sensors of the sensing unit 100 according to the present invention may be connected to a sensor node, thereby enabling efficient configuration. In addition, the LoRa communication can be encrypted with the AES128 method, thereby improving the security of the data.

The MQTT protocol is a messaging protocol optimized for mobile devices or low bandwidth, small devices and is suitable for communication with mobile devices such as user terminal 200 in the present invention and is optimized for small devices such as the situation sensing device 100 Messaging protocol, it is possible to communicate more efficiently than using the HTTP protocol.

When communicating with the user terminal 200, the communication unit 130 can perform communication using the BLE communication method.

The control unit 250 generates the accident detection notification and the accident related information in the form of a message or a communication packet. The accident detection notification and the accident related information may be transmitted through the communication unit 130 in the form of a message or a communication packet.

The information collecting unit 140 may further include an information collecting unit 140, a storage unit 150 and a control unit 160. The information collecting unit 140 may collect apple related data when it is determined that an accident has occurred And various data including the collected data may be stored in the storage unit 150. The control unit 160 may control operations of the sensing unit 110, the situation determination unit 120, the communication unit 130, the information collecting unit 140, and the storage unit 150.

The accident related information collected by the information collecting unit 140 may include the running state of the vehicle, the position, the speed at the time of an accident, and the damage state of the vehicle.

The storage unit 150 stores the two-wheel drive state table 400 and the two-wheel vehicle inclination table 500. The situation determination unit 120 can determine the driving state and the accident state of the vehicle by referring to the two-wheel vehicle running state table 400 and the two-wheel vehicle inclination table 500 stored in the storage unit 150. [ In addition, the storage unit 150 may store a reference time used to determine a driving state and an accident state of the vehicle.

When the user terminal 200 receives the notification information, it can be displayed on the screen of the user terminal. For example, an alert message, an input remaining time, and an input icon, as shown in FIG. The notification message indicates a message informing that an accident has occurred in the motorcycle. The user can confirm that the notification information has been received from the situation sensing apparatus 100 through this.

The input remaining time indicates a remaining time after which the user command, that is, an accident confirmation command, can be issued after the notification information is received. The input remaining time can be updated by a timer. For example, the input remaining time may be updated in seconds and displayed on the screen of the user terminal 200. The user can input an accident confirmation command only within the time specified in the input remaining time.

The input icon may indicate the input state of the user command. When the touch screen function is provided to the user terminal 200, the user can input an accident confirmation command by dragging the input icon. Alternatively, the user can input an accident confirmation command using various buttons or the like configured in the user terminal 200. [

In addition, the dangerous situation detection system for a two-wheeled vehicle using the sensor according to the present invention includes a plurality of user terminals 200, and may display the current position of another user terminal on the screen of the user terminal 200. At this time, it is preferable that the application is installed in the user terminal 200 and the above-described operation is performed by the installed application.

For example, in the case of a two-wheeled bicycle such as a bicycle or a motorcycle, a plurality of users may rally through a variety of meetings or conventions. At this time, if an application is installed for each user terminal 200 and the location of another user terminal is displayed through the application, the user of the user terminal 200 can easily check which part of the user is located, In the case of the operator, it becomes possible to efficiently recognize and manage whether there is a person who falls behind.

In addition, the user terminal 200 may be provided with a GPS module and an application, and the present location of the two-wheeler can be determined through the GPS module. At this time, the application installed in the user terminal 200 can provide at least one or more of information about the main sightseeing spot, the information about the accommodation, and the recommended route based on the current location of the motorcycle.

FIG. 8 shows information on major sightseeing places based on the present location of the two-wheeled vehicle, FIG. 9 shows information on hotels based on the current location of the two-wheeled vehicle, and FIG. Information indicating a recommended route is displayed based on the location.

Referring to FIG. 11, the present invention may further include a helmet 700 worn by a user have. The helmet 700 may include an impact sensor (not shown). The impact sensor senses the amount of impact applied to the helmet 700. At this time, a separate communication module may be installed in the helmet 700 to transmit the amount of impact measured by the impact detection sensor to the situation sensing apparatus 100.

In this configuration, the situation sensing apparatus 100 can determine the state of the motorcycle based on the amount of the transmitted impact. Since the information is insufficient to determine that an accident has occurred due to the acceleration and inclination as described above, the accuracy may be somewhat lowered. The accuracy of the judgment can be improved by using the amount of impact applied to the helmet 700 as a judgment criterion.

For example, when the amount of impact applied to the helmet 700 is equal to or greater than a predetermined threshold value when the two-wheeled vehicle is tilted at a slope equal to or greater than a predetermined threshold value, the situation sensing apparatus 100 can determine that an accident occurred in the two- After such a determination, the situation sensing apparatus 100 can transmit notification information to the user terminal 200, and subsequent operations can be performed as described above.

Also, when the notification information is received, the management server 300 according to the present invention can identify and store the location of the CCTV in the surrounding area based on the location of the two-wheeled vehicle. The CCTV in the surrounding area based on the stored location of the two- Location information can be useful in post-processing of accidents.
