Hereinafter, embodiments for carrying out the present invention will be described in detail based on examples.

First, an embodiment of the accident prevention system of the present invention will be described. Seventy-five percent of traffic accidents are caused by human factors such as falling asleep, inattention signals ahead, looking aside, and driving indiscriminately, and all accidents caused by those human factors (accidents of 100% responsibility of the other party) It accounts for one-third of accidents. Furthermore, in the event of a large-scale disaster such as an earthquake, the evacuated vehicle will be congested and unable to move, and will be forced to pass through, resulting in frequent traffic accidents.

In this embodiment, when a sign of the cause of an accident appears, a caution signal is issued to the driver, etc. by voice, vibration, etc., and at the same time, the occurrence of an abnormality is transmitted to the vehicles running in parallel to provide an accident prevention device. By operating it, the purpose is to prevent "serious accidents" such as rear-end collisions.

In this embodiment, a vital sensor is used to grasp the driver's vital signs or life signs (including physical abnormalities, dozing, overwork, etc.). FIG. 1 (A) shows the arrangement of the vital sensor in this embodiment. The contact-type vital sensor 10 is provided on the back side of the seat belt 12, the handle 14, the back portion of the driver's seat 16, and the like. The non-contact vital sensor 20 is installed at an appropriate position such as the dashboard 22 or the like. When the vital sensor 20 is built in a smartphone (not shown), it may be used. In particular, the vital sensor 10 provided on the seatbelt 12 can be moved and removed with respect to the seatbelt 12 because it can be accurately detected by matching the physique of the driver. As the power source of the vital sensors 10 and 20, a power source prepared in the vehicle may be used, or a solar cell may be used as a power source such as "Beacon with a solar cell sensor" manufactured by Fujitsu Limited.

As the contact type vital sensor 10, for example, "aams. Nursing care" manufactured by Biosilver Co., Ltd. is used. This is a non-contact, non-restraint, non-invasive mat-type biosensor that can detect biometric information on heartbeat, respiration, and body movement. As the non-contact vital sensor 20, there is a non-contact vital sensor manufactured by Mio Corporation. This allows non-contact biological sensing with microwaves, and can detect pulse and respiration with high accuracy from the activity of the subject or the movement of the body surface at rest.

FIG. 1B shows the configuration of the accident prevention system 100 using the above-mentioned vital sensors 10 and 20. As shown in the figure, the vital sensors 10 and 20 are connected to the vital change extracting means 110, and the vital change extracting means 110 includes a vibration means 112, a display means 114, a sounding means 116, and a caution signal transmitting means 120. It is connected to the caution signal receiving means 122 and the hazard lamp 130.

Of these, the vital change extracting means 110 has a function of extracting changes in the vital data of the driver obtained by the vital sensors 10 and 20 and determining whether or not an abnormality has occurred in the driver. for example,
a, when the heart rate and respiratory rate exceed a certain level,
b. When an unusual body movement is detected,
In some cases, it is determined that the driver has suffered an abnormality such as overwork or falling asleep. When the above-mentioned vital change is extracted, the vital change extracting means 110 outputs a drive signal to the vibrating means 112, the display means 114, and the sounding means 116.

Next, the vibrating means 112 is installed on, for example, a seat belt 12, a steering wheel 14, a driver's seat 16, or the like, and has a function of performing warning vibration when a drive signal is input. The display means 114 has a function of displaying a warning to that effect on a display of an automobile, a display of a navigation device, a smartphone, or the like. The sounding means 116 has a function of outputting a warning sound to notify an abnormality from a speaker of an automobile, a speaker of a navigation device, a smartphone, or the like.

Next, the entire operation of this embodiment will be described. Vital data such as the driver's heartbeat is detected by the vital sensors 10 and 20 and input to the vital change extraction means 110. When the vital change extracting means 110 extracts a change from the input vital data, the vital change extracting means 110 outputs a drive signal to the vibrating means 112, the display means 114, and the sounding means 116. Then, in the automobile, the vibrating means 112 vibrates, and the display means displays the fact on the 114, or the sounding means 116 outputs a warning sound. As a result, the driver is alerted that an abnormality has occurred in the vital signs. The driver can be aware of physical abnormalities due to overwork, dozing, etc., and slows down, stops, and takes a break to avoid or prevent accidents.

In particular, it is effective to attach the vital sensor 10 to the seat belt 12. In the case of a Japanese car, the seat belt 12 passes from the driver's right shoulder to above the left hip. Therefore, the vital sensor 10 has an advantage that it is easy to detect vital data from the driver's lungs and heart. In winter, it is difficult to detect vital data due to heavy clothing. Therefore, for example, the vital sensor 10 can be attached to and detached from the seatbelt 12 with a magnet or the like, and the vital sensor 10 can be removed from the seatbelt 12 in winter. , Attach it under your jacket.

Next, a second embodiment using the caution signal transmitting means 120, the caution signal receiving means 122, and the hazard lamp 130 shown in FIG. 1B will be described. When the vital change extracting means 110 extracts a change from the vital data as described above, the attention signal transmitting means 120 transmits a caution signal. For example, as shown in FIG. 2, a caution signal is output from the accident prevention system 100A of the vehicle 30A in front to the following vehicle 30B, and the hazard lamp 130A blinks. Then, it is received by the caution signal receiving means 122 of the accident prevention system 100B of the following vehicle 30B, and the vital change extracting means 110 outputs a caution signal from the caution signal transmitting means 120 and blinks the hazard lamp 130B. This operation is repeatedly performed for the following vehicle and the parallel running vehicle.

On the other hand, the driver of the following vehicle 30B recognizes that some abnormality has occurred because the hazard lamp 130A of the vehicle 30A in front blinks. Further, as described above, the vibration means 112, the display means 114, and the sounding means 116 in the vehicle are driven. As a result, the driver can take accident avoidance measures such as decelerating and stopping.

Further, the caution signal output from the accident prevention system 100A of the vehicle 30A is also transmitted to the smartphone 150 owned by the pedestrian 32 within a certain distance. The smartphone 150 that has received the caution signal evokes the caution signal by vibrating, displaying, and sounding. As a result, the pedestrian 32 can know that the vehicle 30A driven by the driver who has the abnormality is nearby. For example, if a nursery teacher is taking a walk for a child, he / she can promptly take evacuation action to prevent him / her from being involved in an accident.

Next, Example 3 of the present invention will be described with reference to FIG. In the accident prevention system 200 of this embodiment, the vehicle-mounted camera 202, the seatbelt sensor 204, and the caution signal receiving means 122 are connected to the input side of the collision detecting means 206, and the brake 208 is connected to the output side of the collision detecting means 206. , The caution signal transmitting means 120, and the hazard lamp 130 are connected.

As the in-vehicle camera 202, for example, a drive recorder or a camera of a smartphone may be used. The seatbelt sensor 204 is a sensor for detecting that pressure is applied to the seatbelt. When a sudden brake is applied, the driver's body moves greatly forward, but the seatbelt supports the body that is about to jump forward at this time, so that pressure is applied to this seatbelt. This is detected by the seat belt sensor 204. The operations of the caution signal receiving means 122, the caution signal transmitting means 120, and the hazard lamp 130 are the same as those in the above-described embodiment.

Explaining the operation of this embodiment, when the vehicle-mounted camera 202 captures the front of the vehicle and the collision detecting means 206 determines that an accident such as a rear-end collision cannot be avoided due to the relationship between the speed and the inter-vehicle distance, the brake 208 is applied. Drive. The brake 208 is also driven when the collision detecting means 206 detects a sudden brake from the detected pressure of the seatbelt sensor 204. Then, the automobile brakes and stops, and the hazard lamp 130 blinks to avoid an accident.

Further, as in the above embodiment, the fact that the brake 208 is driven is transmitted from the caution signal transmitting means 120 to the following vehicle and the parallel running vehicle, and similarly, the hazard lamp 130 of those vehicles is blinked and the brake 208 is driven. do. In addition, a pedestrian 32 nearby is also informed to that effect. As described above, according to the present embodiment, when the possibility of a collision occurs, the brake is driven to stop the vehicle, so that a collision accident can be avoided.

Next, Example 4 of the present invention will be described with reference to FIG. The collision tracking system 300 of this embodiment has a configuration in which an in-vehicle camera 310, a GPS (positioning system) 312, and a transmitter 314 are provided in the automobile 302.

There is. The collision management server 320 is provided on the cloud and stores images and GPS information transmitted from the automobile 302 together with the date and time. Information other than the image and GPS information may be saved at the same time. Further, a police officer may take a picture of the scene with a smartphone and transmit the image and GPS information to the collision management server 320.

Next, to explain the operation of this embodiment, when an impact occurs due to a collision or the like in the automobile 302, the image captured by the in-vehicle camera 310 and the GPS information measured by the GPS 312 are transmitted by the transmitter 314 to the collision management server 320. Will be sent to. The collision management server 320 creates a database of received images and GPS information together with the date and time of reception. On the other hand, the police officer who arrives at the accident site inputs the data of the accident occurrence date and time and the accident occurrence location on the information terminal 330 such as a smartphone as shown on the screen GA, and turns on the search start switch. Then, those data are transmitted to the collision management server 320, and the collision management server 320 refers to the database and transmits the image and GPS information corresponding to the date and time and place of reception to the information terminal 330. On the information terminal 330, the position of the corresponding automobile is displayed on the map as shown on the screen GB, or the image is displayed as shown on the screen GC.

Further, in this embodiment, when the accident vehicle is away from the scene and is not found at the scene, the police officer uses the information terminal 330 to turn on the tracking start switch. Then, the collision management server 320 transmits the GPS information of the suspected vehicle to the GPS tracking means 340, and the suspected vehicle is tracked using the GPS information. The data on the collision management server is deleted after a certain period of time.

Next, Example 5 of the present invention will be described with reference to FIG. The same reference numerals are used for the same configurations as those in the above-described embodiment. The purpose of this embodiment is to collect information on the disaster site and secure the passage of emergency vehicles in the event of a disaster. In FIG. 5, in the disaster information system 400 of the present embodiment, a large number of the above-mentioned automobiles 302 are traveling, and the images captured by these are transmitted to the disaster image server 420. Further, the image taken by the camera 332 of the information terminal 330 is also transmitted to the disaster image server 420 in the same manner. For example, a case where a police officer or the like at a disaster site takes a picture voluntarily or based on an instruction from a disaster countermeasures headquarters 422 or the like is applicable.

The disaster video server 420 stores the received video together with the GPS information in the database. As a storage method, for example, the video is first divided into 47 prefectures, and then divided into each municipality under each prefecture. The area is specified using GPS information. The images stored in the database are distributed to related parties such as the disaster countermeasures headquarters 422, police 424, firefighting 426, electric companies, and gas companies (not shown).

Further, the disaster video server 420 is also connected to the emergency route navigation means 440 so that a route through which a vehicle can pass is searched when a disaster occurs. The emergency route navigation means 440 is equipped with a function to search for routes while avoiding impassable roads and congested roads, and the searched emergency routes are disaster response headquarters 422, police 424, firefighting 426, etc. It is designed to be delivered to related parties.

Next, the entire operation of this embodiment will be described. As described above, the disaster video server 420 stores images of the disaster site transmitted from the automobile 302 and the information terminal 330. Related parties such as the disaster countermeasures headquarters 422, police 424, and fire department 426 specify the area where the disaster is occurring and send it to the disaster video server 420. Then, the disaster video server 420 transmits the disaster video of the corresponding area to the related parties. Disaster images sent to "large screens", "small screens", etc. are displayed at related parties, and the situation of the disaster can be grasped by these and used for rescue measures.

For example, if a heavy rain warning signal is issued to Honjo City, Saitama Prefecture, display the corresponding screen on the personal computer of the Disaster Countermeasures Headquarters 422 of Honjo City Hall, and from the "Heavy Rain Information" column, select "Saitama Prefecture" → "Honjo City". If you search in the order of "", the disaster video sent from each vehicle traveling in Honjo City will be sent to the personal computer.

In the event of a large-scale disaster, the communication infrastructure may not function, but even in such an environment, it is possible to send and receive disaster images by using DTN (Delay / Disruption Tolerant Network). .. In addition, although it is assumed that ordinary communication devices cannot be used, for example, video without delay is used using the "uncompressed analog-digital radio for video and audio," which is a delay-free video transmission device of Giga Technovision Co., Ltd. Make transmission.
