Description

[Technical Field]

[0001] The present disclosure relates to a technique for notifying a train that a vehicle is stopped at a railroad crossing and that an emergency stop of the train is required. [Background technology]

[0002] If a vehicle stops and becomes stranded at a railroad crossing due to reasons such as a wheel slipping or stalling, it is necessary to notify the train that the vehicle is stranded in order to avoid a collision with the train.

[0003] Patent Document 1 discloses a vehicle condition determination device that automatically sends an emergency signal to a railroad crossing warning device or train when a vehicle becomes stuck at a railroad crossing due to a wheel runoff or stall, and displays the condition to the driver. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-006813 Summary of the Invention [Problem to be solved by the invention]

[0005] Railroad crossings are equipped with railroad crossing emergency buttons as safety devices to notify trains that a vehicle has become stuck at the crossing. According to the vehicle state determination device of Patent Document 1, a driver who recognizes an emergency situation based on the display on the display setting unit can press the railroad crossing emergency button to notify trains scheduled to pass through the crossing that an emergency stop is required.

[0006] However, if the driver of the stranded vehicle is elderly or has difficulty walking, they are unable to quickly get out of the vehicle and operate the railroad crossing emergency button, which poses a problem in that they are unable to notify the train that an emergency stop is required. Patent Document 1 describes that an emergency situation occurrence signal is automatically sent from the vehicle state determination device to the railroad crossing warning device or the train, but does not describe the specific method for this.

[0007] The present disclosure has been made to solve the above-mentioned problems, and aims to notify the train when a vehicle carrying a person with walking difficulty stops at a railroad crossing. [Means for solving the problem]

[0008] The emergency information notification device disclosed herein comprises an alarm detection unit that detects that a crossing barrier alarm is sounding, a stopped vehicle detection unit that detects that a vehicle is stopped, a crossing detection unit that detects that a vehicle is inside a crossing, a walking difficulty determination unit that detects that a passenger in the vehicle has walking difficulty, and a drone control unit that controls the flight of at least one drone to notify the driver of a train that is scheduled to pass through the crossing while the crossing barrier alarm is sounding that the vehicle is stopped inside the crossing when a vehicle carrying a person with walking difficulty is stopped inside the crossing and the crossing barrier alarm is sounding. [Effects of the Invention]

[0009] According to the emergency information notification device disclosed herein, if a vehicle carrying a person with walking difficulty stops at a railroad crossing where a crossing barrier alarm is sounding, the drone can notify the train of this. [Brief explanation of the drawings]

[Figure 5] It is a diagram showing the hardware configuration of the emergency information notification device according to Embodiment 1. [Figure 6] It is a diagram showing the hardware configuration of the emergency information notification device according to Embodiment 1.

Mode for Carrying Out the Invention

[0011] <A. Embodiment 1> <A-1. Configuration> FIG. 1 is a block diagram showing the configuration of an emergency information notification device 101 according to Embodiment 1 and its peripheral devices. The emergency information notification device 101 is a device that notifies a train attempting to pass through a level crossing that it should make an emergency stop when a vehicle is stuck inside the level crossing.

[0012] The emergency information notification device 101 is connected to a microphone 21, a storage device 22, an RTC (real-time clock) 23, a vehicle speed sensor 24, a map data storage device 25, a GPS (Global Positioning System) antenna 26, a camera 27, a display device 28, a first drone 30, and a second drone 40, and is configured to be able to use these.

[0013] In this specification, the vehicle to which the emergency information notification device 101 sends a notification is simply referred to as a vehicle.

[0014] The microphone 21 is mounted on the vehicle and acquires the sound outside the vehicle.

[0015] Sound data of a level crossing warning sound is stored in the storage device 22 in advance. In addition, data photographed by the camera 27 for determining the walking difficulty of the driver is stored in the storage device 22.

[0016] The RTC 23 generates time information and transmits it to the emergency information notification device 101.

[0017] The vehicle speed sensor 24 detects the speed of the vehicle and transmits speed information indicating the detected speed to the emergency information notification device 101 .

[0018] Map data is stored in the map data storage device 25. This map data includes location information of railroad crossings.

[0019] The GPS antenna 26 is mounted on the vehicle and receives GPS signals.

[0020] The camera 27 is mounted on the vehicle and captures images of the outside of the vehicle. The camera 27 has a built-in battery so that it can be started even when the vehicle engine (ACC) is off.

[0021] The display device 28 is mounted on the vehicle and displays information to notify the driver of an emergency. The display device 28 is, for example, a liquid crystal display.

[0022] The first drone 30 is mounted on, for example, a vehicle, flies under the control of the emergency information notification device 101, and presses a railroad crossing emergency button installed at the railroad crossing. Figure 2 is a diagram showing the first drone 30. The first drone 30 is equipped with propellers 31 and 32 for flight, a camera 33, four first robot arms 34, 35, 36, and 37, and one second robot arm 38.

[0023] The second drone 40 is mounted on, for example, a vehicle and flies from the vehicle toward the train under the control of the emergency information notification device 101 to notify the train driver that the vehicle is stopped at the railroad crossing. For example, the emergency information notification device 101 communicates with the train's traffic management device to acquire the current position of a train scheduled to pass through the railroad crossing. Based on the current position of the train, the second drone 40 flies along the tracks from the vehicle toward the train. Alternatively, if the second drone 40 is equipped with a camera, the second drone 40 may be launched from the vehicle under the control of the emergency information notification device 101, capture an image of a train direction indicator attached to a railroad crossing alarm, and transmit the image to the emergency information notification device 101. The emergency information notification device 101 may then determine the flight direction of the second drone 40 based on the direction of the arrow indicating the train's direction of travel displayed on the train direction indicator. FIG. 3 is a diagram illustrating the second drone 40. The second drone 40 is equipped with propellers 41 and 42 for flight and a display board 43. A message urging the train driver to urgently stop the train is displayed on the display board 43. This message is displayed, for example, using a red LED so that the train driver can see it from a distance even at night.

[0024] The emergency information notification device 101 includes an alarm detection unit 11, a stopped vehicle detection unit 12, a railroad crossing detection unit 13, a walking difficulty determination unit 14, and a drone control unit 15.

[0025] The warning detection unit 11 determines whether or not a railroad crossing warning sound is sounding by using the microphone 21 and the storage device 22. The determination of whether or not a railroad crossing warning sound is sounding is also referred to as a railroad crossing warning sound determination. Specifically, the warning detection unit 11 compares the sound data received from the microphone 21 with the sound data of the railroad crossing warning sound stored in advance in the storage device 22, and if the two match, it determines that the railroad crossing warning sound is sounding, and if the two do not match, it determines that the railroad crossing warning sound is not sounding. The warning detection unit 11 outputs the result of the railroad crossing warning sound determination to the stop detection unit 12.

[0026] The stop detection unit 12 acquires the result of the railroad crossing warning sound determination from the warning detection unit 11, and if it is determined that the railroad crossing warning sound is sounding, it determines whether the vehicle is stopped using the RTC 23 and the vehicle speed sensor 24. The determination of whether the vehicle is stopped is also referred to as a stop determination. Specifically, the stop detection unit 12 uses the time information transmitted from the RTC 23 to determine that the vehicle is stopped when a predetermined time or more has passed while the vehicle speed obtained from the vehicle speed sensor 24 is in a state of "0 km / h." The stop detection unit 12 outputs the result of the stop determination to the railroad crossing detection unit 13.

[0027] The inside-railroad crossing detection unit 13 receives the result of the stop determination from the stop detection unit 12, and if it is determined that the vehicle is stopped, it determines whether or not the vehicle is located within a railroad crossing using the map data storage device 25, the GPS antenna 26, and the camera 27. The determination of whether or not the vehicle is located within a railroad crossing is also referred to as inside-railroad crossing determination. Specifically, the inside-railroad crossing detection unit 13 identifies the vehicle's position from the GPS signal received by the GPS antenna 26, and determines whether or not the vehicle is located within a railroad crossing by comparing the identified vehicle position with the map data read from the map data storage device 25. The inside-railroad crossing detection unit 13 outputs the result of the inside-railroad crossing determination to the walking difficulty determination unit 14.

[0028] Note that the railroad crossing detection unit 13 may not be able to determine whether a vehicle is inside a railroad crossing located under an elevated track using only GPS signals and map data, or may erroneously determine that the vehicle is inside a railroad crossing even though it is outside the crossing. Therefore, the railroad crossing detection unit 13 may improve the accuracy of the railroad crossing determination by using image recognition by the camera 27 in addition to the GPS signals and map data. If the image captured by the camera 27 recognizes that there are tracks on the side of the vehicle, the railroad crossing detection unit 13 can determine that the vehicle is inside a railroad crossing. This is because there are no obstacles on the tracks and it is assumed that all the tracks are similar.

[0029] The walking difficulty determination unit 14 receives the result of the railroad crossing detection from the railroad crossing detection unit 13. When it is determined that the vehicle is located within a railroad crossing, the walking difficulty determination unit 14 determines whether the driver of the vehicle has walking difficulty, i.e., whether the driver has walking difficulty, by using the storage device 22 and the camera 27. The determination of whether the driver has walking difficulty is also referred to as walking difficulty determination. The walking difficulty determination unit 14 calculates the driver's walking speed from the driver's walking behavior captured by the camera 27 before boarding the vehicle. For example, the walking difficulty determination unit 14 can calculate the driver's walking speed from the time it takes the driver to arrive at the vehicle from a position a predetermined distance from the vehicle. If the walking speed is below a predetermined threshold, the walking difficulty determination unit 14 determines that the driver has walking difficulty. Furthermore, the walking difficulty determination unit 14 can determine that the driver has walking difficulty if it detects that the driver is using a cane or wheelchair to get to the vehicle.

[0030] The walking difficulty determination unit 14 outputs the result of the walking difficulty determination to the drone control unit 15. Furthermore, when the walking difficulty determination unit 14 does not determine that the driver has walking difficulty, it causes the display device 28 to display an emergency message instructing the driver to press an emergency stop button, and ends the processing.

[0031] The drone control unit 15 controls the first drone 30 and the second drone 40.

[0032] First, we will explain the control of the first drone 30. The drone control unit 15 acquires the result of the walking difficulty determination from the walking difficulty determination unit 14, and if it is determined that the driver has walking difficulty, it performs control to have the first drone 30 press the railroad crossing emergency button. Specifically, the drone control unit 15 determines the approximate direction in which the railroad crossing emergency button is installed from the image captured by the camera 27, and launches the first drone 30 in that direction.

[0033] When the first drone 30 approaches approximately the location where the level crossing emergency button is installed, the drone control unit 15 determines the exact location where the level crossing emergency button is installed from the video captured by the camera 33 built into the first drone 30, guides the first drone 30 to the level crossing emergency button, and causes the first drone 30 to press the level crossing emergency button.

[0034] Next, the control of the second drone 40 will be described. The drone control unit 15 acquires the result of the walking difficulty determination from the walking difficulty determination unit 14, and when it is determined that the driver is a person with walking difficulties, performs control to notify the train driver that the vehicle has stopped inside the level crossing. Specifically, the drone control unit 15 determines the direction in which the train is approaching the level crossing from the video captured by the camera 27, and launches the second drone 40 in that direction. The train here is the scheduled passing train that is scheduled to pass through the level crossing while the level crossing alarm sound is sounding.

[0035] Note that it is not always necessary for the drone control unit 15 to control both the first drone 30 and the second drone 40. It is sufficient if at least one of the controls can be performed. Also, it is not necessary for the vehicle to be equipped with both the first drone 30 and the second drone 40. Only one drone having the functions of both the first drone 30 and the second drone 40 may be mounted on the vehicle, and depending on the situation, the drone control unit 15 may perform the above one of the controls on that one drone.

[0036] In the above, it was explained that the processing proceeds in the order of the alarm detection unit 11, the stop detection unit 12, the in-level-crossing detection unit 13, and the walking difficulty determination unit 14, but the order of the processing does not necessarily have to be this way. For example, the emergency information notification device 101 may be provided with a control unit, and the control unit may acquire the determination results from the alarm detection unit 11, the stop detection unit 12, the in-level-crossing detection unit 13, and the walking difficulty determination unit 14, and determine whether to fly the first drone 30 and the second drone 40. ​​​​Next, a flowchart from when the emergency information notification device 101 detects a railroad crossing alarm sound to when it launches a drone will be described with reference to FIG.

[0038] First, in step S101, the key lock of the vehicle is released. The key lock of the vehicle is released, for example, by the driver pressing the unlock button on the vehicle key. Once the key lock is released, in step S102, the camera 27 is activated, and a video of the driver's walking until arriving at the vehicle is captured, and the captured video is stored in the storage device 22. Note that the key lock release shown here is an example of the activation timing of the camera 27. The camera 27 may also be activated at a timing other than the key lock release. For example, the emergency information notification device 101 may measure the distance of the key from the vehicle by receiving a beacon periodically transmitted from the vehicle key, and may activate the camera without releasing the key lock when the key approaches within a certain distance from the vehicle.

[0039] When the driver arrives at the driver's seat, he turns on the vehicle engine (ACC) in step S103. When the engine (ACC) is turned on, the microphone 21 is activated in step S104, and its voice recognition function is turned on.

[0040] Thereafter, in step S105, the warning detection unit 11 determines whether or not a railroad crossing warning sound is being sounded around the vehicle, that is, performs a railroad crossing warning sound determination. If a railroad crossing warning sound is not being sounded, the warning detection unit 11 repeats the processing of step S105.

[0041] If the railroad crossing warning sound is sounding, in step S106, the vehicle stop detection unit 12 determines whether the vehicle is stopped, i.e., performs a vehicle stop determination. The vehicle stop detection unit 12 may perform the vehicle stop determination based on whether the engine is stopped. If the vehicle is not stopped in step S106, the emergency information notification device 101 returns to the processing of step S105. In other words, the railroad crossing warning sound determination is repeated until the vehicle stops.

[0042] If the vehicle is stopped in step S106, the railroad crossing detection unit 13 determines whether the vehicle is inside a railroad crossing in step S107, i.e., performs a railroad crossing determination. If the vehicle is not inside a railroad crossing in step S107, the processing of the emergency information notification device 101 returns to step S105. In this way, the emergency information notification device 101 repeats the railroad crossing determination until the railroad crossing warning sound stops sounding, and if the railroad crossing warning sound stops sounding, repeats the railroad crossing warning sound determination again.

[0043] If the vehicle is within a railroad crossing in step S107, the walking difficulty determination unit 14 determines in step S108 whether or not a passenger such as the driver has walking difficulty, that is, performs a walking difficulty determination. The walking difficulty determination may be performed not only after it has been determined that the vehicle is within a railroad crossing, but also at any timing after the engine (ACC) is turned on. If it is determined in step S108 that the passenger does not have walking difficulty, the walking difficulty determination unit 14 causes the display device 28 to display an emergency message urging the passenger to press the railroad crossing emergency button, and the processing of the emergency information notification device 101 ends.

[0044] If the occupant is determined to be a person with walking difficulties in step S108, the drone control unit 15 performs flight control of the drones in step S109. Here, the drone control unit 15 performs flight control of at least one of the first drone 30 and the second drone 40. When flight control of the first drone 30 is performed, the first drone 30 flies to the location where the railroad crossing emergency button is installed and stabilizes the first drone 30 relative to the railroad crossing emergency button by grasping the housing on which the button is installed with the four first robot arms 34, 35, 36, and 37. To prevent accidental operation, the railroad crossing emergency button is designed so that it will not activate unless pressed with strong force. Therefore, the first drone 30 firmly grasps the housing on which the button is installed with the first robot arms 34, 35, 36, and 37, and then strongly presses the railroad crossing emergency button using the second robot arm 38.

[0045] When the flight control of the second drone 40 is performed, the second drone 40 flies toward the train while displaying a message on the display board 43 notifying that the vehicle is stopped within the level crossing, and notifies the situation to the driver of the train.

[0046] <A-3. Effect> As described above, the emergency information notification device 101 according to Embodiment 1 includes an alarm detection unit 11 that detects that the blocking machine alarm sound of the level crossing is sounding, a stop detection unit 12 that detects that the vehicle is stopped, a within-level crossing detection unit 13 that detects that the vehicle is within the level crossing, a walking difficulty determination unit 14 that detects that a passenger of the vehicle is a person with difficulty walking, and when a vehicle in which a person with difficulty walking is riding is stopped within the level crossing and the blocking machine alarm sound is sounding, a drone control unit 15 that performs flight control of at least one drone to notify the driver of a passing scheduled train, which is a train scheduled to pass through the level crossing while the blocking machine alarm sound is sounding, that the vehicle is stopped within the level crossing. Therefore, according to the emergency information notification device 101, when the vehicle is in trouble within the level crossing, flight control of the drone for stopping the passing scheduled train can be performed only when the passenger of the vehicle is a person with difficulty walking. When the drone is flown, there is a possibility that the drone will come into contact with the driver or a person around the vehicle. Therefore, it is not appropriate to fly the drone recklessly. On the other hand, since the damage caused by the vehicle coming into contact with the train is more serious than the damage caused by the drone coming into contact with a person, according to the emergency information notification device 101, the drone is flown only when the passenger of the vehicle is a person with difficulty walking. Examples of contact between the drone and a person include contact between the first drone 30 trying to press the emergency stop button and the driver or another person also trying to press the emergency stop button, or contact between the second drone 40 trying to notify the driver of the passing scheduled train that the vehicle is stopped within the level crossing and a person who has entered the level crossing for rescue.

[0047] <B. Hardware Configuration> 5 and 6 are diagrams illustrating an example of the hardware configuration of the emergency information notification device 101. The functions of the alarm detection unit 11, the stopped vehicle detection unit 12, the railroad crossing detection unit 13, the walking difficulty determination unit 14, and the drone control unit 15 (hereinafter, referred to as the alarm detection unit 11, etc.) in the emergency information notification device 101 are realized by processing circuits. That is, the emergency information notification device 101 includes a processing circuit for realizing each function of the alarm detection unit 11, etc. The processing circuit may be a processing circuit 81, which is dedicated hardware, as shown in FIG. 5, or a processor 82 that executes a program stored in a memory 83, as shown in FIG. 6.

[0048] 5, when the alarm detection unit 11 and the like are dedicated hardware, the processing circuit 81 corresponds to, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-programmable Gate Array), or a combination thereof. The functions of each unit of the alarm detection unit 11 and the like may be realized by different processing circuits, or the functions of each unit may be realized together by a single processing circuit.

[0049] As shown in FIG. 6, when the alarm detection unit 11, etc. is a processor 82, the functions of the alarm detection unit 11, etc. are realized by software, firmware, or a combination of software and firmware. The software or firmware is written as a program and stored in the memory 83. The processor 82 realizes each function of the alarm detection unit 11, etc. by reading and executing the program stored in the memory 83. In other words, the emergency information notification device 101 includes a memory 83 for storing a program that, when executed by the processor 82, results in the execution of each step shown in FIG. 4. It can also be said that these programs cause a computer to execute the procedure or method of the alarm detection unit 11, etc.

[0050] Here, the processor 82 refers to, for example, a CPU (Central Processing Unit), processing device, arithmetic device, processor, microprocessor, microcomputer, or DSP (Digital Signal Processor), etc. The memory 83 may be, for example, a non-volatile or volatile semiconductor memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable ROM), or EEPROM (Electrically EPROM), or may be a magnetic disk such as a hard disk or flexible disk, or may be an optical disk such as a minidisk, CD (Compact Disc), or DVD (Digital Versatile Disc).

[0051] It should be noted that some of the functions of the alarm detection unit 11 and the like may be realized by dedicated hardware, and some by software or firmware. In this way, the processing circuit in the emergency information notification device 101 can realize each of the above functions by hardware, software, firmware, or a combination of these.
