FIG. 1 is a functional block diagram showing the overall configuration of the danger occurrence point information collection system. The danger occurrence point information collection system 1 includes a communication network (a communication network in which a mobile communication network and a fixed communication network are interconnected) with an in-vehicle device 2 mounted on a vehicle and a danger occurrence point information collection device 3 installed in a center. ) Is configured to be able to communicate with each other.

  The in-vehicle device 2 includes a pulse wave sensor 21 (reflective pulse wave measuring means according to the present invention), an electrocardiographic sensor 22 (electrocardiographic measuring means according to the present invention), a wireless communication device 23 (transmitting means according to the present invention, Receiving means), GPS receiver 24 (vehicle position detecting means in the present invention), vehicle speed sensor 25 (vehicle speed detecting means in the present invention), brake sensor 26 (brake depression amount detecting means in the present invention), accelerator sensor 27 (Accelerator depression amount detecting means in the present invention), an omnidirectional camera 28 (vehicle surrounding photographing means in the present invention), an audio output device 29, and a display device 30 are connected.

  The pulse wave sensor 21 is a reflection type pulse wave sensor having a wristwatch type (wristband type) shape. For example, the pulse wave sensor 21 measures the pulse wave of the driver while being worn on the wrist of the driver, and the measurement result is as follows. Is transmitted to the in-vehicle device 2. The electrocardiographic sensor 22 is embedded, for example, in the steering so as to face the driver, measures the driver's electrocardiogram (heart rate), and transmits the measurement result to the in-vehicle device 2. The wireless communication device 23 performs a wireless communication operation with the danger occurrence point information collection device 3 in accordance with a communication instruction from the in-vehicle device 2. The GPS receiver 24 detects the vehicle position and transmits the detection result to the in-vehicle device 2. The vehicle speed sensor 25 detects the vehicle speed and transmits the detection result to the in-vehicle device 2.

  The brake sensor 26 detects the amount of brake depression and transmits the detection result to the in-vehicle device 2. The accelerator sensor 27 detects the amount of accelerator depression (accelerator opening) and transmits the detection result to the in-vehicle device 2. The omnidirectional camera 28 captures the vehicle periphery and transmits the captured vehicle periphery image to the in-vehicle device 2. In this case, the vehicle surrounding image is not limited to the image outside the passenger compartment that is simply viewed by the driver, but may be an image including the passenger compartment including the driver. The audio output device 29 performs an audio output operation in accordance with an audio output instruction from the in-vehicle device 2. The display device 30 performs a display operation in accordance with a display instruction from the in-vehicle device 2. Note that some of the devices and devices mounted on these vehicles may be configured with known navigation devices, such as the GPS receiver 24 and the display device 30 configured with known navigation devices. .

  The danger occurrence point information collecting device 3 is configured by connecting a communication device 31 and a near-miss map database 32. The communication device 31 performs a communication operation with the in-vehicle device 2 in accordance with a communication instruction from the danger occurrence point information collection device 3. The danger occurrence location information collection device 3 is configured to store information related to the danger occurrence location in the near incident map database 32 as danger occurrence location information (near incident map) using a GIS (Geographic Information System).

  Next, the operation of the above configuration will be described with reference to FIGS. Here, FIG. 2 shows a process performed by the in-vehicle device 2 as a flowchart, and FIG. 3 shows a process performed by the danger occurrence point information collecting device 3 as a flowchart.

  In the activated state, the in-vehicle device 2 inputs the measurement result obtained by measuring the driver's pulse wave from the pulse wave sensor 21 (step S1), and the measurement result obtained by measuring the driver's electrocardiogram from the electrocardiographic sensor 22. The blood pressure is calculated based on the time difference (pulse wave propagation time) from the R wave peak of the electrocardiogram to the R wave peak of the pulse wave (step S3).

  Next, the in-vehicle device 2 determines whether or not the vehicle is traveling based on the detection result of the vehicle speed detected by the vehicle speed sensor 25 (step S4), and detects that the vehicle is not traveling (step S4). "NO"), the process returns to the above-described step S1, and step S1 and subsequent steps are repeated.

  In contrast, when the in-vehicle device 2 detects that the vehicle is running (“YES” in step S4), the in-vehicle device 2 calculates the blood pressure calculated according to the above procedure and the electrocardiogram measured by the electrocardiographic sensor 22. Based on the correlation between blood pressure and heart rate and physical condition information shown in FIG. 4, the level of sleepiness / tensity is estimated (step S5). Then, the in-vehicle device 2 determines whether the estimated level of sleepiness / tensity is below a predetermined level or higher than a predetermined level (step S6). The blood pressure and heart rate and the level of sleepiness / tensity are correlated as shown in FIG. 4, and it is estimated that the level of sleepiness is high when the blood pressure is low and the heart rate is low, On the other hand, when the blood pressure is high and the heart rate is high, the level of tension is estimated to be high. The degree of deviation from the state where the blood pressure is moderate and the heart rate is moderate (near the center shown in FIG. 4) is determined whether the level of drowsiness / tension is below a predetermined level or above a predetermined level. Determine based on.

  Here, when the in-vehicle device 2 detects that the estimated level of drowsiness / tension is less than a predetermined level (a state where the driver is in a normal condition and has a low degree of danger) (“NO” in step S6). Then, it is determined whether or not it is the regular transmission timing set in advance for every predetermined time or every predetermined distance (step S7). When the in-vehicle device 2 detects that it is the regular transmission timing (“YES” in step S7), the in-vehicle device 2 determines the estimated drowsiness / tense level and the vehicle position detected by the GPS receiver 24 as a wireless communication device. 23 is transmitted to the danger occurrence point information collecting device 3 (step S8). On the other hand, when the in-vehicle device 2 detects that it is not the regular transmission timing (“NO” in step S7), the in-vehicle device 2 transmits the estimated level of sleepiness / tensity from the wireless communication device 23 to the danger occurrence location information collecting device 3. Without (discarding), the process returns to step S1 described above, and step S1 and subsequent steps are repeated.

  On the other hand, the in-vehicle device 2 detects that the estimated level of drowsiness / tensity is equal to or higher than a predetermined level (a state where the driver's physical condition is abnormal and the risk level is high) ("YES" in step S6). )), A warning operation is performed (step S9). The warning action here is intended to alleviate the user's drowsiness and tension, or to encourage a break. For example, “Drowsiness is increasing. Take a break” or “Relax For example, a warning sound message such as “Please keep it in mind” or an operation for outputting a preset warning sound from the voice output device 29. In this case, the in-vehicle device 2 is detected not only by the estimated sleepiness / tensity level and the vehicle position detected by the GPS receiver 24 but also by the vehicle speed detected by the vehicle speed sensor 25 and the brake sensor 26. The amount of depression of the brake, the amount of depression of the accelerator detected by the accelerator sensor 27, and the vehicle surroundings image taken by the omnidirectional camera 28 are also transmitted from the wireless communication device 23 to the danger occurrence point information collecting device 3 (step S10).

  The danger occurrence location information collection device 3 determines whether or not the level of drowsiness / tension is received from the in-vehicle device 2 by the communication device 31 (step T1). Here, when the danger occurrence location information collecting device 3 detects that the level of drowsiness / tension is received from the in-vehicle device 2 by the communication device 31 (“YES” in step T1), the received drowsiness / tensity is received. It is determined whether or not the level is periodically transmitted according to the periodic transmission timing in the in-vehicle device 2 (step T2).

  Here, when the danger occurrence location information collecting device 3 detects that the received drowsiness / tense level is periodically transmitted from the in-vehicle device 2 (“YES” in step T2), the in-vehicle device 2 is detected. Therefore, only the vehicle position is received together with the sleepiness / tense level, and the received sleepiness / tensity level and the vehicle position are associated with each other and stored in the near-miss map database 32 (step T3). That is, when the received drowsiness / tension level is periodically transmitted from the in-vehicle device 2, the danger occurrence location information collection device 3 has a drowsiness / tension level lower than a predetermined level. That is, since the driver's physical condition is normal and the risk level is low, the level of drowsiness / tensity and the vehicle position are simply associated with each other and stored in the near-miss map database 32.

On the other hand, when the danger occurrence location information collecting device 3 detects that the received drowsiness / tense level is not a periodically transmitted signal from the in-vehicle device 2 ("NO" in step T2).
Since not only the vehicle position but also the vehicle speed, the brake depression amount, the accelerator depression amount, and the vehicle surrounding image are received from the in-vehicle device 2 together with the vehicle drowsiness and tension level, the received sleepiness and tension level The vehicle position, the vehicle speed, the brake depression amount, the accelerator depression amount, and the vehicle surrounding image are associated and stored in the near-miss map database 32 (step T4). That is, if the received drowsiness / tension level is not regularly transmitted from the in-vehicle device 2, the danger occurrence location information collection device 3 has a drowsiness / tension level equal to or higher than a predetermined level. Since the driver's physical condition is abnormal and the danger level is high, the level of sleepiness / tensileness, the vehicle position, the vehicle speed, the brake depression amount, the accelerator depression amount, and the vehicle surrounding image are associated with each other and the near-miss map database 32 To store.

  In this case, the danger occurrence point information collection device 3 transmits a warning signal from the communication device 31 to the in-vehicle device 2 (step T5). In response to this, when the in-vehicle device 2 detects that the wireless communication device 23 has received a warning signal from the danger occurrence location information collecting device 3, it performs a warning operation.

  In the series of processes described above, the in-vehicle device 2 displays the heart rate and the relative blood pressure that change with time as shown in FIG. The level change is displayed in 5 levels. Further, as shown in FIG. 6, the danger location information collecting device 3 distinguishes a near-miss map into a near-miss map database 32 by distinguishing between a point where the level of drowsiness / tension is less than a predetermined level and a point where the level is above a predetermined level. Store. In this case, a point where the level of drowsiness / tension is less than a predetermined level and a point where the level is above a predetermined level may be distinguished by a color difference.

  As described above, according to the present embodiment, the in-vehicle device 2 transmits the level of drowsiness / tensity based on the driver's electrocardiogram and blood pressure and the vehicle position to the danger occurrence location information collecting device 3, The occurrence location information collecting device 3 is configured to collect the level of drowsiness / tension based on the driver's electrocardiogram and blood pressure received from the in-vehicle device 2 and the vehicle position as information on the occurrence location of the danger. It is possible to appropriately collect information on the location, and in this case, the configuration is such that the pulse wave of the driver is measured by the reflection type pulse wave sensor 21, so that the mounting site of the pulse wave sensor 21 is limited. In addition, there is no physical discomfort and it is possible to improve the usability for the driver.

  In addition, when the level of drowsiness / tension in the in-vehicle device 2 is less than a predetermined level, the level of drowsiness / tension and the vehicle position are periodically transmitted according to a preset periodic transmission timing. On the other hand, if the level of drowsiness / tension is equal to or higher than a predetermined level, the level of drowsiness / tension, vehicle position, vehicle speed, brake depression, accelerator depression, and vehicle surroundings image will not be in accordance with the regular transmission timing. Since it is configured to transmit immediately, it is possible to efficiently transmit the sleepiness / tensity level based on the necessity of transmitting the sleepiness / tensity level.

  Further, when the drowsiness / tension level is equal to or higher than a predetermined level in the in-vehicle device 2, the drowsiness / tension level and the vehicle position are transmitted, and the vehicle speed, brake depression amount, accelerator depression amount, and vehicle surrounding image are transmitted. In addition to the drowsiness / tension level and the vehicle position, the danger occurrence location information collection device 3 also generates a vehicle speed, a brake depression amount, an accelerator depression amount, and a vehicle surrounding image. It can be collected as information on the location, and the location where the danger has occurred can be analyzed in detail.

  Further, since the in-vehicle device 2 is configured to perform a warning operation when the level of drowsiness / tension is equal to or higher than a predetermined level, the user is immediately notified that the level of drowsiness / tension is equal to or higher than a predetermined level. The user can immediately realize that the level of drowsiness / tension is equal to or higher than a predetermined level.

The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
