Description

The present invention relates to a management support system that supports the management of the driving state of a driver who drives a target vehicle.

Conventionally, the biological signal of the driver is acquired in real time, and when it is determined that the physical condition is not suitable for driving by analyzing and analyzing this biological signal, a break is urged or an alarm is generated to awaken the driver. There is a device. As such a device, a device that detects and judges an electroencephalogram (see Patent Document 1 below), a device that judges from information on heart rate, blood pressure, and autonomic nerves (see Patent Document 2 below), and the like are known. ..

Japanese Patent No. 6132327 Japanese Unexamined Patent Publication No. 2014-27961

The degree of fatigue and drowsiness of the driver greatly affects the driving condition. In general, drivers are encouraged to stop their vehicles and take breaks if they feel tired or drowsy in order to drive safely.

On the other hand, since the driver is also a human being, geographical environmental factors such as the destination point to be transported and the planned rest point are approaching, and the psychology of wanting to deliver the package to the destination point as soon as possible. Due to environmental factors, it is possible that one may be overconfident in one's physical condition and continue driving. In such a case, if each of the above devices is mounted on the vehicle, it is possible to objectively know one's physical condition by the notification of the warning sound and to act as a motivation for taking a break. ..

By the way, the carrier owns a plurality of vehicles and employs a large number of drivers. From the viewpoint of safety management, the carrier often wants to manage the driving condition of each driver. However, each of the above devices has been developed for the purpose of making the driver aware by emitting a warning sound in each vehicle. That is, even if these devices are mounted on each vehicle, it is not possible to manage the driving state of each driver at a distant place.

Recent advances in IoT technology have led to the development of technologies that enable communication between devices in various fields. Based on this point, the present inventors first provide a separate communication means for a device for monitoring a driver's biological signal during driving, as described in the above patent document, and the device. When a warning sound was notified to the vehicle from Japan, we considered installing a function to send warning information to that effect to the server.

By adopting such a configuration, the administrator can know that each driver is in poor physical condition by accessing the server. Further, since the manager can recognize the deterioration of the driver's physical condition, he / she can verbally instruct the driver to take a break by using, for example, a mobile phone. As a result, it is possible to force the driver to take a break, which is expected to have the effect of preventing accidents.

However, in a carrier that employs many drivers, the number of drivers to be managed by the manager is inevitably large. In this case, the administrator needs to keep monitoring the server, and there is a problem that the work load imposed on the administrator increases.

To solve such a problem, a method of causing the server to transmit the information to the administrator's terminal when the server receives the warning information transmitted from the device mounted on the vehicle is conceivable. Be done. Specifically, it is conceivable to adopt a mechanism in which an alert is notified to a terminal such as a smartphone or a personal computer owned by the administrator. However, even with this method, in the case of a carrier that employs an extremely large number of drivers, it is expected that notifications will be sent to the administrator's terminal with high frequency. There is a problem that a high work load is imposed.

Through diligent research, the present inventor has found that one of the backgrounds of such a problem is related to the characteristics of the device itself that detects the above-mentioned biological signal and monitors the physical condition of the driver. That is, the above device is configured to generate a warning sound when the driver's biological signal deviates even a little from the value set as the normal value from the viewpoint of preventing accidents during driving as much as possible. It is common that it is done. Therefore, even if a warning sound is emitted from the detected biological signal, the driver's health condition may actually be comparable to that in normal times. This is related to the fact that there are individual differences in the correlation between the information detected by the biological signal and the actual physical condition of the driver.

Therefore, if a communication means is provided in the above-mentioned device and a function of transmitting information to the effect that a warning sound is generated from the above-mentioned device is provided to the server, the above-mentioned information is notified to the terminal of the administrator who manages a large number of drivers. The frequency of being done becomes high. Further, as described above, even when the signal indicating that the warning sound is emitted is notified, there is a case where there is no problem in the physical condition of the actual driver. It is not possible to recognize whether or not the state really requires monitoring. However, there are circumstances in which the occurrence of major accidents must be prevented. In other words, when the above system is operated, the administrator is required to monitor many drivers at the same time based on the information that is notified in large numbers, which also imposes a high workload on the administrator. It will be imposed.

In view of the above problems, the present invention provides a management support system that enables an administrator to focus on monitoring a driver when the driver is in an operating state that really needs to be monitored. The purpose is.

The present invention is a management support system that supports the management of the driving state of the driver who drives the target vehicle.

A second monitoring device mounted on the target vehicle and monitoring the driver's physical condition during driving,

It is equipped with an administrator terminal configured to enable wireless communication with the server.
When the traveling state satisfies a predetermined first warning condition, the first monitoring device outputs a first warning signal in the target vehicle and outputs the first monitoring information corresponding to the traveling state at the source. It is transmitted to the server together with the identification information for identifying the target vehicle or the driver.
When the driving physical condition condition satisfies a predetermined second warning condition, the second monitoring device outputs a second warning signal in the target vehicle and outputs the second monitoring information corresponding to the driving physical condition. , Sent to the server with the identification information,
The server
A receiving unit that receives the first monitoring information transmitted from the first monitoring device and the second monitoring information transmitted from the second monitoring device.
A storage unit in which the monitoring-required determination condition for determining whether the driving state of the driver is at the monitoring-required level is stored, and the storage unit.
A determination processing unit that determines whether or not the monitoring required determination condition is satisfied based on the first monitoring information and the second monitoring information received by the receiving unit.
When the determination processing unit determines that the monitoring required determination condition is satisfied, the identification information provides the administrator terminal with monitoring required notification information indicating that the driving state of the driver is at the monitoring required level. At the same time, it is characterized by including a transmission unit for transmitting to the administrator terminal.

In the present specification, the "manager" does not necessarily have to be a legal "operation manager", but refers to a person who has an operation authority for the "manager terminal".

The management support system determines whether or not the driving state of the driver is at the monitoring required level based on the information transmitted from the first monitoring device and the second monitoring device mounted on the target vehicle. The first monitoring device is a device that monitors the running state of the target vehicle. The second monitoring device is a device that monitors the driver's physical condition during driving.

The first monitoring device outputs a first warning signal in the target vehicle when the traveling state of the target vehicle satisfies a predetermined first warning condition. For example, when the target vehicle suddenly brakes, or when the distance between the target vehicle and an obstacle in front (vehicle, pedestrian, etc.) becomes extremely short, the first monitoring device detects these situations and at the same time. , Outputs the first warning signal in the vehicle. The first warning signal may be a warning sound emitted from a speaker or the like, or may be character or image information displayed at a position visible to the driver such as a meter panel or a navigation screen. Further, a vibrator may be provided on the seat on which the driver sits to give vibration. By recognizing the first warning signal, the driver recognizes that the driving condition satisfies the first warning condition. This acts as a motivation for safe driving.

The second monitoring device outputs a second warning signal in the target vehicle when the driver's physical condition during driving satisfies a predetermined second warning condition. For example, the second monitoring device outputs a second warning signal in the vehicle when it detects that the driver is suffering from drowsiness or fatigue. Like the first warning signal, the second warning signal may be a warning sound emitted from a speaker or the like, or a character or an image displayed at a position visible to the driver such as a meter panel or a navigation screen. It may be information. By recognizing the second warning signal, the driver recognizes that he / she is suffering from drowsiness and fatigue. This has the effect of awakening the driver's consciousness.

When the first monitoring device detects that the traveling state satisfies the first warning condition, the first monitoring device transmits information corresponding to the traveling state (first monitoring information) to the server together with the identification information. Similarly, when the second monitoring device detects that the driving physical condition condition satisfies the second warning condition, the second monitoring device transmits information corresponding to the driving physical condition state (second monitoring information) to the server together with the identification information. The server determines in the determination processing unit whether or not the driving state of the driver is at the monitoring required level based on the first monitoring information and the second monitoring information transmitted from each device.

It is assumed that the warning conditions (first warning condition, second warning condition) are strictly set for the first monitoring device and the second monitoring device for the purpose of ensuring the safety of operation.

For example, in the case of the first monitoring device, if another vehicle suddenly cuts in from the adjacent lane, it may detect that the inter-vehicle distance has narrowed and determine that the first warning condition is satisfied. obtain. That is, although there is no particular problem in the driving state of the driver, the driving state may affect the driving state of another vehicle and satisfy the first warning condition. Therefore, it is difficult to truly judge whether or not the driver feels tired or drowsy only from the monitoring result of the first monitoring device.

Further, the second monitoring device is a device for monitoring the physical condition during driving, and as an example, it monitors based on the biological signal of the driver. However, the correlation between the value indicated by the driver's biological signal and the actual physical condition of the driver varies from driver to driver. Therefore, it is difficult to truly judge whether or not the driver feels tired or drowsy from only the monitoring result of the second monitoring device.

The server provided in the management support system according to the present invention includes a storage unit, which stores the first monitoring information transmitted from the first monitoring device and the second monitoring information transmitted from the second monitoring device in advance. Based on the above, the monitoring-required determination condition for determining whether the operating state is at the monitoring-required level is stored. If the driving condition of the target vehicle and the driving condition of the driver satisfy certain conditions, it is considered that the driving condition is not good and an accident may occur. As an example, it is said that the first monitoring device detects that a large number of large changes in acceleration have occurred within a predetermined time, and the second monitoring device tends to cause drowsiness to the driver multiple times. The case where it is detected corresponds.

The server provided in the management support system according to the present invention is for the administrator terminal only when it is determined that the driving state of the driver is at the monitoring required level based on the first monitoring information and the second monitoring information. And send the monitoring required notification information to that effect. That is, according to the management support system according to the present invention, when a warning condition is set for each of the first monitoring device and the second monitoring device, and a situation occurs in which a warning is notified from each device. Even so, if it is not determined that monitoring of the driver is really necessary, the notification to the administrator terminal is not performed. As a result, the administrator only needs to pay attention to the driver associated with the monitoring-required information as a monitoring target only when the monitoring-required notification information from the server is notified to the administrator terminal, which is a management burden. Is reduced.

The first monitoring device and the second monitoring device each have a function of outputting a warning signal into the vehicle independently of each device. Therefore, even when the first monitoring device or the second monitoring device is mounted alone in the vehicle, there is a certain effect of making the driver aware of safe driving. However, as described above, it is common that the conditions for outputting a warning signal are strictly set so that each device can maximize the function of preventing accidents when it is mounted alone. .. In such a case, it is possible that the warning signal is frequently output in the vehicle even though the driver himself / herself has no problem with his / her physical condition. If such a state continues, the driver becomes accustomed to outputting the warning signal in the vehicle, and the significance of the warning signal is reduced.

On the other hand, as described above, according to the management support system according to the present invention, when it is determined that monitoring of the driver is really necessary, the administrator terminal is automatically notified. .. When the administrator detects that this notification has been given, he / she can confirm the current physical condition of the driver by using means such as a mobile phone and wireless communication. That is, even if the driver has become accustomed to the warning signal from the first monitoring device or the second monitoring device mounted on the vehicle, such a case can be obtained from the manager only when the monitoring is really necessary. Since confirmation is made, it is possible to re-recognize that one's physical condition is not so good, and it can be a motivation such as taking a break.

More specifically
The first monitoring information includes information quantified according to the degree of danger of the traveling state.
The second monitoring information includes information quantified according to the degree of unawakening of the driver.
When the receiving unit receives the first monitoring information and the second monitoring information, the receiving unit stores the first monitoring information and the second monitoring information together with the identification information which is the source and the time information regarding the reception date and time. Remember in the club,
The monitoring required determination condition includes information regarding the monitoring target occurrence time interval and the occurrence number threshold, which are determined according to the danger level and the non-awakening level.
The determination processing unit is described in the first monitoring information within the monitoring target generation time interval based on the first monitoring information, the second monitoring information, and the time information stored in the storage unit. When the number of occurrences including the risk degree and the non-awakening degree described in the second monitoring information exceeds the occurrence number threshold value, it can be determined that the monitoring required determination condition is satisfied.

For example, when the driver feels drowsy or tired, the frequency of occurrence of specific driving conditions such as sudden braking, sudden acceleration, and sudden steering tends to increase. Further, when the driver feels drowsy or tired in this way, the second monitoring device determines that the driver's physical condition during driving is in a state of high unawakening based on the driver's biological signal. The frequency of judgment increases. That is, according to the above management support system, when a state showing a high degree of danger and a high degree of unawakening is detected with high frequency within a limited time, the server truly changes the driving state of the driver. It is determined that the monitoring level is required, and the administrator terminal is automatically notified to that effect.

More specifically
The first monitoring device includes the distance between the target vehicle and a front obstacle (vehicle, pedestrian, etc.) located in front of the target vehicle, whether or not the target vehicle deviates from the lane in which the target vehicle is traveling, and the target. At least one of the accelerations of the vehicle is detected, and the preset risk level is determined based on the detection result.
The second monitoring device may detect at least one of the driver's heartbeat and pulse wave, and determine the preset degree of unawakening based on the detection result.

The storage unit may store the monitoring required determination condition according to the identification information.

As described above, there may be individual differences in the correlation between the information obtained from the second monitoring device and the true physical condition (sleepiness, fatigue level) of the actual driver. In addition, there may be individual differences in the correlation between the information obtained from the first monitoring device and the degree of danger of the actual driving state, depending on the number of years of driving and the driving skill of the driver. According to the above configuration, it is possible to set the monitoring required judgment condition in consideration of the individual characteristics of each driver, so that the determination accuracy of whether or not the driving state of the driver is at the monitoring required level can be further improved. Can be done.

Further, the storage unit stores information on the pre-driving physical condition, which is the physical condition of the driver before driving the target vehicle, in association with the identification information.
The server may be provided with a correction processing unit that corrects the monitoring required determination condition for each driver based on the pre-driving physical condition.

For example, if the driver's body temperature is slightly higher than normal heat before driving, it is expected that he / she will be more likely to get tired than usual. Further, for example, when the driver is in a state before driving and the state of the autonomic nerve is not preferable, it is expected that drowsiness is more likely to occur or the driver tends to drive indiscriminately than in normal times. In such a case, for example, the correction processing unit corrects the driver's monitoring-required determination condition so as to be stricter than usual. As a result, even in a case where the monitoring required notification information is not normally notified to the administrator terminal, the administrator terminal is notified, so that the administrator focuses on monitoring the driver. can do.

The management support system is mounted on the target vehicle, and the change is made when the road on which the target vehicle travels is changed from a general road to a highway and when the highway is changed to the general road. It is equipped with a driving road determination device that transmits information to that effect to the server together with information regarding the changed time.
The storage unit may store the monitoring-required determination condition that differs depending on whether the road on which the target vehicle travels is the general road or the expressway.

When driving on a general road and when driving on a highway, the mode of driving condition and the way of feeling fatigue are different. According to the above configuration, since the monitoring required determination condition can be switched according to the mode of each road, it is possible to further improve the determination accuracy of whether or not the driving state of the driver is at the monitoring required level. As the driving road determination device, for example, an ETC (automatic toll collection system) mounted on the target vehicle can be used.

The management support system includes a position information detecting device mounted on the target vehicle, detecting the current position information of the target vehicle, and transmitting the current position information to the server.
The server
When the first monitoring information or the second monitoring information is received by the receiving unit, the position information of the target vehicle at the time of reception is stored in the storage unit together with the respective monitoring information.
When the determination processing unit determines that the monitoring required determination condition is satisfied, the transmitting unit may transmit the monitoring required notification information to the administrator terminal together with the identification information and the location information. ..

According to the above configuration, the administrator can recognize the current position of the driver based on the position information displayed on the administrator terminal. Therefore, for example, it is possible to inform the driver of an appropriate break point existing near the position information. As the position information detection device, for example, a car navigation system mounted on the target vehicle can be used.

According to the management support system of the present invention, when a driver is in a driving state that really needs monitoring, it is possible to support the manager so that the driver can be monitored intensively. ..

[First Embodiment]
The first embodiment of the management support system according to the present invention will be described with reference to the drawings. This management support system is used to support the management of the driving state of the driver who drives the target vehicle.

FIG. 1 is a block diagram schematically showing the overall configuration of the management support system. The management support system 1 includes a target vehicle 10, a server 60, and an administrator terminal 80.

<Target vehicle 10>
The target vehicle 10 is a vehicle driven by the driver 2. In the present embodiment, the case where the target vehicle 10 is a truck for transporting cargo will be described as an example, but the vehicle may be a vehicle used for a purpose in which the driver 2 drives and travels between a plurality of points. For example, it may be another vehicle such as a bus or a taxi.

The target vehicle 10 includes a first monitoring device 20 and a second monitoring device 30 mounted in the vehicle. Both the first monitoring device 20 and the second monitoring device 30 are configured to enable wireless communication with the server 60. The format of this communication is not limited, and for example, Wi-Fi (registered trademark), the Internet, and the like can be used.

(First monitoring device 20)
The first monitoring device 20 is a device that monitors the traveling state of the target vehicle 10. More specifically, as shown in FIG. 2, the first monitoring device 20 travels on the target vehicle 10 based on the results detected by the detection unit 21 and the detection unit 21 that detect the traveling state of the target vehicle 10. It includes a determination unit 22 for determining whether or not the state satisfies a predetermined warning condition, a warning output unit 23 for outputting a warning signal, and a transmission unit 24 for transmitting predetermined information to the server.

The detection unit 21 includes an acceleration sensor that detects the acceleration of the target vehicle 10, an image sensor that detects a distance from an obstacle in front (such as a vehicle or a pedestrian), and / or an image pickup sensor that detects a lane deviation situation. Further, the first monitoring device 11 may include a speed sensor that detects the speed of the target vehicle 10. Some of these sensors may be composed of sensors mounted on the target vehicle 10 itself.

The determination unit 22 determines whether or not the traveling state of the target vehicle 10 satisfies a predetermined warning condition (hereinafter referred to as "first warning condition") based on various information of the target vehicle 10 detected by the detection unit 21. It is an arithmetic processing unit that determines the above, and is composed of dedicated software and / or hardware. The first warning condition is stored in advance in a storage unit (not shown) in the first monitoring device 20.

FIG. 3 is a table showing the correspondence between an example of the first warning condition and the information quantified according to the degree of danger of the traveling state according to each condition. In addition, in FIG. 3 and FIG. 5 described later, the determination value is described as "mn" (m and n are both numbers), but the former "m" is the device from which the data is acquired. It indicates the type of (sensor), and the latter "n" indicates the degree of danger by replacing it with a numerical value. The device from which data is acquired corresponds to the first monitoring device 20, the second monitoring device 30, and / or the acceleration sensor or the image pickup sensor in the first monitoring device 20. The notation method of the determination value is an example and is not limited to this method.

(1) When the detection unit 21 detects that the target vehicle 10 has crossed the lane without issuing a turn signal while the target vehicle 10 is traveling at a predetermined speed or higher (for example, 55 km / h or more), the determination unit 22 performs this travel. A judgment value 1-1 (left lane) or a judgment value 1-2 (right lane) is set for the state.

(2) Based on the information detected by the detection unit 21, the determination unit 22 takes less than a predetermined number of seconds (for example, 3 seconds) to reach the point where the vehicle in front was when the target vehicle 10 continues to run at the same vehicle speed. When it is determined that the following) is satisfied, the determination value 1-3 is set for this traveling state.

(3) Based on the information detected by the detection unit 21, the determination unit 22 enters the vehicle body of the target vehicle 10 within a preset virtual bumper range while the target vehicle 10 is traveling at a low speed (for example, 30 km / h or less). If it is determined that this is the case, the determination values 1-4 are set for this traveling state.

(4) Based on the information detected by the detection unit 21, the determination unit 22 has a risk of colliding with the vehicle in front within a predetermined second (for example, 2.5 seconds) when the target vehicle 10 continues to run at the same vehicle speed. If it is determined that there is, a determination value 1-5 is set for this traveling state.

(5) Based on the information detected by the detection unit 21, the determination unit 22 determines that there is a risk of the target vehicle 10 colliding with a pedestrian in front while traveling, and determines this traveling state. Set the value 1-6.

(6) Based on the change in acceleration detected by the detection unit 21, the determination unit 22 determines the determination value 2-1 (danger level) for this running state according to the size of G generated in the target vehicle 10. Set small), 2-2 (medium risk), and 2-3 (high risk). Judgment value 2-3 is the operation with the highest degree of danger. At the time of this determination, the determination unit 22 may detect the timing at which the engine is started and exclude the change in acceleration at the same timing from the first warning condition. Further, the determination value 2-1 may be excluded from the first warning condition.

When the determination unit 22 determines that the traveling state of the target vehicle 10 satisfies the condition (first warning condition) as shown in the above example, the first monitoring device 20 is targeted by the warning output unit 23. A warning signal (first warning signal) is output to the inside of the vehicle 10. At this time, the first monitoring device 20 sends information (first monitoring information d1) indicating the running state of the target vehicle 10 at this time from the transmission unit 24 to the server 60 together with the identification information di of the driver 2. And send.

The warning output unit 23 is a means for generating and outputting a corresponding audio signal or a character or image signal, and is composed of dedicated software and / or hardware. Based on the information determined by the determination unit 22, the transmission unit 24 converts the first monitoring information d1 into transmission data associated with the identification information di of the driver 2, and then transmits the transmission data to the server 60 via wireless communication. It is a means for transmitting the information, and is composed of dedicated software and / or hardware.

The first warning signal may be a mode that can be recognized by the driver 2, and may be, for example, an audio signal output from a speaker mounted on the first monitoring device 20 or the target vehicle 10. It may be a character or image signal output on the screen mounted on the monitoring device 20 or the target vehicle 10. As another example, it may be a vibration signal from a vibrator output to the seat on which the driver 2 sits. Further, when the first monitoring device 20 and the smartphone owned by the driver 2 are configured to be communicable, audio signals and character / image signals are output to the smartphone of the driver 2. It doesn't matter.

At that time, the first warning signal may include information indicating the content of the warning. For example, when the first monitoring device 20 determines that the vehicle is in a traveling state corresponding to the determination value 1-1, an audio signal indicating that the target vehicle 10 is out of the lane with respect to the left side is output from the speaker. However, the text information and the image information indicating that the target vehicle 10 is out of the lane with respect to the left side may be displayed on the screen.

The driver 2 recognizes that the driving state satisfies the first warning condition by recognizing the voice, characters, and image information corresponding to the first warning signal in the target vehicle 10. .. As a result, the driver 2 is encouraged to pay attention to the subsequent driving.

The first monitoring information d1 transmitted from the first monitoring device 20 to the server 60 includes the content of the corresponding warning. As an example, the first monitoring information d1 includes each determination value shown in FIG.

Further, as described above, the first monitoring device 20 sends the identification information di for identifying the driver 2 together with the first monitoring information d1 to the server 60. The first monitoring device 20 may store, for example, information (vehicle number or the like) for identifying the mounted target vehicle 10, or stores information of the driver 2 (employee ID or the like). It doesn't matter if you have one. In the former case, the number of the target vehicle 10 is described as the identification information di, and for example, the server 60 stores a table in which the current correspondence status between the target vehicle 10 and the driver 2 is described in advance. It doesn't matter. In the latter case, the employee ID of the driver 2 is described as the identification information di. In this case, the process of temporarily storing the employee ID of the driver 2 in the first monitoring device 20 may be performed before the driver 2 gets on the target vehicle 10.

(Second monitoring device 30)
The second monitoring device 30 is a device that monitors the physical condition of the driver 2 during driving. More specifically, as shown in FIG. 4, the second monitoring device 30 is based on the results detected by the detection unit 31 and the detection unit 31 that detect the driving physical condition of the driver 2. A determination unit 32 for determining whether or not a predetermined warning condition is satisfied during operation, a warning output unit 33 for outputting a warning signal, and a transmission unit 34 for transmitting predetermined information to a server are provided.

The detection unit 31 is composed of, for example, a sensor provided on the seat on which the driver 2 sits, and detects biological signals such as the driver 2's heartbeat and pulse wave. A pressure sensor can be used as an example.

The determination unit 32 identifies the driving physical condition of the driver 2 based on various biological signals of the driver 2 detected by the detection unit 31, and the specified driving physical condition is a predetermined warning condition (hereinafter referred to as a warning condition). , "Second warning condition") is determined, and is composed of dedicated software and / or hardware. The second warning condition is stored in advance in a storage unit (not shown) in the second monitoring device 30.

FIG. 5 shows an example of a physical condition during driving specified by the determination unit 32 based on various biological signals of the driver 2 and a correspondence relationship between determination values corresponding to each state.

(1) When the determination unit 32 determines that the seating of the driver 2 cannot be confirmed based on the information of the biological signal detected by the detection unit 31, the determination unit 32 determines the physical condition during driving of the driver 2. Set the value 3-0. This setting is not required.

(2) When the determination unit 32 determines that the sympathetic nerve of the driver 2 is enhanced and is in an excited state based on the information of the biological signal detected by the detection unit 31, the driver 2 is driving. When the judgment value 3-1 is set for the physical condition and it is judged that the driver 2 feels no or almost no fatigue, the judgment value 3-2 is set for the driver 2's driving physical condition. To set. The determination values 3-1 and 3-2 correspond to the state in which the driver 2 has a low degree of non-awakening (high degree of arousal).

(3) When the determination unit 32 determines that the driver 2 is in a state in which drowsiness is likely to occur based on the information of the biological signal detected by the detection unit 31, the driver 2's physical condition during driving is determined. When it is determined that the driver 2 feels tired, the determination value 3-4 is set for the driver 2's physical condition during driving. The determination values 3-3 and 3-4 correspond to a state in which the degree of non-awakening of the driver 2 is not so low (the degree of arousal is not so high).

(4) When the determination unit 32 determines that the driver 2 is drowsy based on the information of the biological signal detected by the detection unit 31, the determination unit 32 determines that the driver 2 is in a physical condition during operation. When the determination value 3-5 is set and it is determined that the sign of falling asleep of the driver 2 is detected, the determination value 3-6 is set for the driving physical condition of the driver 2. The determination values 3-5 and 3-6 correspond to the state in which the driver 2 has a high degree of non-awakening (low degree of arousal).

(5) When the determination unit 32 determines that the driver 2 cannot detect the low arousal state (low arousal state) based on the information of the biological signal detected by the detection unit 31, the driver 2 is operating. When the judgment value 3-7 is set for the physical condition and it is determined that the driver 2 is in an imminent sleep state or is definitely in the sleeping state, the judgment value 3-8 is set for the driver 2's driving physical condition. To set. The determination values 3-7 and 3-8 correspond to the state in which the driver 2 has an extremely high degree of unawakening (the degree of arousal is extremely low).

In the present embodiment, when the determination unit 32 determines that the determination value corresponding to the driving physical condition of the driver 2 is 3-3 to 3-8, the warning output unit 33 within the target vehicle 10 A warning signal (second warning signal) is output to. That is, in this embodiment, the second warning condition is set to whether or not the driving physical condition of the driver 2 is 3-3 to 3-8. Further, at this time, the second monitoring device 30 sends information (second monitoring information d2) indicating the driving physical condition of the driver 2 at this time from the transmission unit 34 together with the identification information di of the driver 2 to the server. Send to 60.

The warning output unit 33 is a means for generating and outputting a corresponding audio signal or a character or image signal, and is composed of dedicated software means and / or hardware means. The transmission unit 34 converts the second monitoring information d2 into transmission data associated with the identification information di of the driver 2 based on the information determined by the determination unit 32, and then sends the second monitoring information d2 to the server 60 via wireless communication. It is a means for transmitting the information, and is composed of a dedicated software means and / or a hardware means.

The second warning signal may be a mode that can be recognized by the driver 2, and may be, for example, an audio signal output from a speaker mounted on the second monitoring device 30 or the target vehicle 10. It may be a character or image signal output on the screen mounted on the monitoring device 30 or the target vehicle 10. Further, when the second monitoring device 30 and the smartphone owned by the driver 2 are configured to be communicable, audio signals and character / image signals are output to the smartphone of the driver 2. It doesn't matter.

At that time, the second warning signal may include information indicating the content of the warning. For example, when the second monitoring device 30 determines that the vehicle is in a running state corresponding to the determination value 4-7, an audio signal indicating that the driver 2 feels drowsy may be output from the speaker. , Textual information or image information indicating that the driver 2 feels drowsy may be displayed on the screen.

By recognizing the voice, text, and image information corresponding to the second warning signal in the target vehicle 10, the driver 2 is made to recognize that he / she is suffering from drowsiness and fatigue, and his / her consciousness is awakened. do. As a result, for example, the driver 2 is encouraged to voluntarily encourage a break.

The second monitoring information d2 transmitted from the second monitoring device 30 to the server 60 includes the content of the corresponding warning. As an example, the second monitoring information d1 includes each determination value shown in FIG.

Further, as described above, the second monitoring device 30 sends the identification information di for identifying the driver 2 together with the second monitoring information d2 to the server 60. The second monitoring device 30 may store, for example, information (vehicle number, etc.) for identifying the mounted target vehicle 10, or stores information (employee ID, etc.) of the driver 2. It doesn't matter if you have one.

When each warning signal is composed of an audio signal, the warning signal output from the first monitoring device 20 and the warning signal output from the second monitoring device 30 are assumed to be emitted from the same speaker. It doesn't matter. Similarly, when each warning signal is composed of text or image signals, the warning signal output from the first monitoring device 20 and the warning signal output from the second monitoring device 30 are on the same screen. It does not matter if it is displayed.

<Server 60>
As shown in FIG. 1, in the present embodiment, the server 60 includes a receiving unit 61, a storage unit 62, a determination processing unit 63, and a transmitting unit 64. The receiving unit 61 is a processing means having a function of converting data received via a telecommunications line into a form that can be calculated, and the transmitting unit 64 converts the data into a predetermined transmission / reception mode and telecommunications.

When the receiving unit 61 receives the first monitoring information d1 transmitted from the first monitoring device 20 and the second monitoring information d2 transmitted from the second monitoring device 30, the receiving unit 61 stores the second monitoring information d2 in the storage unit 62. At this time, as described above, since the identification information di for identifying the driver 2 is associated with the first monitoring information d1 and the second monitoring information d2, these monitoring information (d1 and d2) are used. Is stored in the storage unit 62 for each identification information di. Further, the date and time received by the receiving unit 61 or the date and time when each monitoring information (d1 and d2) is transmitted from the target vehicle 10 are also stored.

The determination processing unit 63 has a predetermined determination condition (hereinafter referred to as "monitoring determination condition") based on each monitoring information (d1, d2) for each driver 2 stored (stored) in the storage unit 62. It is determined whether or not the condition is satisfied. Information regarding the monitoring required determination condition is stored in advance in the storage unit 62.

FIG. 6 is a table showing an example of the monitoring determination condition. When the determination processing unit 63 confirms that the reception unit 61 has received the first monitoring information d1 or the second monitoring information d2, the determination processing unit 63 causes the storage unit 62 to start from this reception time and before a predetermined time. During the period, the content and the number of times of the first monitoring information d1 or the second monitoring information d2 associated with the identification information di of the driver 2 are detected.

In the example shown in FIG. 6, the following contents are stored in the storage unit 62 as a monitoring determination condition. In this example, as the monitoring required determination conditions, the monitoring target occurrence time interval (for example, 10 minutes or 30 minutes, etc.) and the occurrence number threshold value (for example, for example) predetermined according to the first monitoring information d1 and the second monitoring information d2.

When the determination processing unit 63 confirms that the above-mentioned monitoring-required determination condition is satisfied, the determination processing unit 63 creates information indicating that the driving state of the driver 2 is at the monitoring-required level (hereinafter, referred to as "monitoring-required notification information da"). do. The transmission unit 64 transmits the monitoring required notification information da together with the identification information di of the driver 2 to the administrator terminal 80.

<Administrator terminal 80>
The administrator terminal 80 is not limited to any device as long as it can communicate with the server 60, and is, for example, a general-purpose device such as a smartphone, a tablet PC, a notebook PC, or a desktop PC, or a management support system 1. It is composed of a dedicated terminal related to. When the administrator terminal 80 is made of a general-purpose device, it may be assumed that a dedicated application program for supporting the operation of the management support system 1 is installed. The administrator terminal 80 may be stored at a position away from the installation location of the server 60, or may be owned (carried) by the administrator.

The administrator terminal 80 has a receiving unit 81 that receives the monitoring required notification information da transmitted from the transmitting unit 64 of the server 60, and a display processing unit 82 that creates display information based on the received monitoring required notification information da. And a display unit 83 for displaying the information created by the display processing unit 82. The receiving unit 81 is a processing means having a function of converting data received via a telecommunication line into an operable mode. The display processing unit 82 is an arithmetic processing unit that performs predetermined signal processing (calculation) based on the acquired information, and is composed of dedicated software and / or hardware. The display unit 83 corresponds to the monitor screen. For example, the display unit 83 and the administrator terminal 80 may be integrally configured as in the case where the administrator terminal 80 is configured by a smartphone, or the administrator terminal 80 may be configured by a desktop PC. In addition, the display unit 83 and the administrator terminal 80 may be configured separately.

FIG. 7 is an example of a screen displayed on the administrator terminal 80 that has received the monitoring required notification information da. In the example shown in FIG. 7, the message display area 88 and the operation area 89 are displayed on the display unit 83.

In the message display area 88, information for identifying the target driver 2 and the target vehicle 10 and information indicating that the monitoring level is required are displayed. Further, in the operation area 89, operation buttons (89a, 89b, ...) That can be operated by the administrator are displayed. In this example, an operation button 89a for viewing the contents of the monitoring required notification information da notified this time in detail and an operation button 89b for contacting the target driver 2 are displayed.

For example, when the administrator operates the operation button 89a, the administrator terminal 80 transmits an instruction signal for acquiring the target information from the transmission unit (not shown) to the server 60. When the server 60 receives this instruction signal, for example, the storage unit 62 transmits each monitoring information (d1, d2) within the latest predetermined time of the target driver 2 to the administrator terminal 80 for management. Information is displayed on the display unit 83 of the personal terminal 80. As a result, the manager can recognize what kind of driving state the target driver 2 has been in most recently.

Further, when the storage unit 62 of the server 60 stores information about the business plan for each driver 2, the information is transmitted from the server 60 to the administrator terminal 80. For example, the time of the monitoring required notification information da notified this time is collated with the information related to the business plan, and for example, the fact that the process is currently in progress from the A point to the B point is displayed on the display unit 83 of the administrator terminal 80. Can be made to.

Further, when the administrator operates the instruction button 89b, the administrator terminal 80 contacts the mobile phone of the driver 2 or the wireless communication device mounted on the target vehicle 10 driven by the driver 2. Can be taken. In this case, the administrator terminal 80 may have a call function and a message transmission function as needed. As a result, the manager can directly orally convey a word to call attention to the driver 2, and can prevent an accident. Further, the administrator terminal 80 may transmit text information to call attention to the mobile phone of the driver 2 or the target vehicle 10 driven by the driver 2.

<Flow chart>
FIG. 8 is a flowchart schematically showing the processing flow of the management support system 1 of the present embodiment. Since the contents are duplicated, the explanation will be simplified.

While the target vehicle 10 is traveling, the first monitoring device 20 monitors the traveling state of the target vehicle 10 (step S11), and the second monitoring device 30 monitors the driving physical condition of the driver 2 (step S21). These monitorings may be performed at all times while the target vehicle 10 is running.

When the first monitoring device 20 determines that the traveling state of the target vehicle 10 satisfies the above-mentioned first warning condition (YES in step S12), the first monitoring device 20 outputs a first warning signal in the target vehicle 10 (step S13). ), The first monitoring information d1 indicating the running state of the target vehicle 10 at this time is transmitted to the server 60 (step S14).

When the second monitoring device 30 determines that the traveling state of the target vehicle 10 satisfies the second warning condition (YES in step S22), the second monitoring device 30 outputs a second warning signal in the target vehicle 10 (step S23). The second monitoring information d2 indicating the operating physical condition of the driver 2 at this time is transmitted to the server 60 (step S24).

When the server 60 receives each monitoring information (d1, d2), it stores it in the storage unit 62 (step S31). Then, the determination processing unit 63 determines whether or not the monitoring required determination condition is satisfied based on the monitoring information (d1 and d2) for each driver 2 stored in the storage unit 62 (step S32). When the monitoring required determination condition is satisfied (YES in step S32), the monitoring required notification information da indicating that the driving state of the driver 2 is at the monitoring required level is transmitted to the administrator terminal 80 (YES in step S32). Step S33).

According to the above configuration, only when the server 60 determines that the target vehicle is at the monitoring required level based on the past driving state of the target vehicle 10 and the driving physical condition of the driver 2, the administrator terminal 80 is contacted. You will be notified to that effect. As a result, the management burden on the administrator is reduced as compared with the case where the administrator confirms each time a warning is issued from the monitoring device (20, 30) mounted on the target vehicle 10.

As described above, the management support system 1 combines the information based on the driving state of the target vehicle 10 and the information based on the physical condition state of the driver 2 to determine whether or not the driving state is at the monitoring required level. ing. Therefore, according to the management support system 1, the accuracy of determining whether or not the state has a high risk is improved. Therefore, when the management support system 1 is operated, the driver 2 can recognize that the state is actually dangerous because the manager directly contacts the system.

That is, according to the management support system 1, each device (20, 30) mounted on the target vehicle 10 is not simply in a state of outputting a warning signal, but in a more dangerous state (a state in which an accident is likely to occur). ) Only, the server 60 notifies the administrator. Therefore, the direct contact from the manager to the driver 2 means that the driver 2 is in a state where there is a possibility that an accident will occur. In other words, the driver 2 was made to recognize that he was driving in a state where there was a possibility that an accident would actually occur due to the direct contact from the manager, and he was able to awaken at least temporarily and was immediately appropriate in the vicinity. It is possible to strongly encourage people to take breaks in various places.

The monitoring required determination condition stored in the storage unit 62 of the server 60 may be set according to the driver 2. The driving physical condition of the driver 2 monitored by the second monitoring device 30 is monitored based on the biological signal of the driver 2. However, where there are individual differences in the biological signal, it is assumed that the content indicated by the determination value determined by the second monitoring device 30 and the actual physical condition of the driver 2 do not always match.

Further, depending on the number of years of driving of the driver 2 and the driving technique, it is assumed that the content indicated by the determination value determined by the first monitoring device 20 and the actual risk level of the target vehicle 10 do not always match. ..

Therefore, in consideration of the tendency of the biological signal of each driver 2 and the driving technique in advance, the monitoring determination condition is set for each driver 2 and stored in the storage unit 62 of the server 60. can do. For example, depending on the driver 2, the monitoring target occurrence time interval and the occurrence number threshold value under the conditions exemplified in FIG. 6 are changed, and the condition of the combination of the first monitoring information d1 and the second monitoring information d2 is changed. be able to.

<Another configuration example>
(1) As shown in FIG. 9, when the target vehicle 10 includes a position information detection device 11 that detects the current position information of the target vehicle 10, each monitoring device (20, 30) has a reference to the server 60. The position information dg of the target vehicle 10 at the time when the monitoring information (d1 and d2) is transmitted may also be transmitted. The position information detection device 11 is composed of, for example, a car navigation system mounted on the target vehicle 10. According to this configuration, the position information dg of the target vehicle 10 at the time when each warning condition is satisfied can be associated with each monitoring information (d1 and d2) and stored in the storage unit 62 of the server 60.

The position information dg is transmitted from the position information detection device 11 to each monitoring device (20, 30), and then from each monitoring device (20, 30) to the server 60 together with each monitoring information (d1, d2). It does not matter if it is transmitted. Alternatively, as another method, when each monitoring information (d1, d2) is transmitted from each monitoring device (20, 30) to the server 60, the position information dg from the position information detecting device 11 to the server 60. May be sent.

Further, as another method, the position information detecting device 11 may periodically transmit the position information dg to the server 60 at predetermined time intervals. In this case, the server 60 stores the position information dg in the storage unit 62, and at the time when each monitoring information (d1, d2) transmitted from each monitoring device (20, 30) is received, the nearest time is reached. The position information dg transmitted to may be read from the storage unit 62.

In step S32, when the determination processing unit 63 determines that the monitoring required determination condition is satisfied based on the monitoring information (d1, d2) for each driver 2 (YES in step S32), the administrator terminal 80 is notified. On the other hand, the monitoring required notification information da indicating that the driving state of the driver 2 is at the monitoring required level is transmitted to the administrator terminal 80 together with the identification information di of the driver 2 and the position information deg.

FIG. 10 is an example of a screen displayed on the administrator terminal 80 that has received the monitoring required notification information da together with the position information deg. In the example shown in FIG. 10, information regarding the position of the target vehicle 10 is simply shown in the message display area 88. In this case, when the administrator operates the instruction button 89a, detailed information regarding the current position of the driver 2 can be displayed on the display unit 83 of the administrator terminal 80. Based on this information, the manager can detect an appropriate resting place near the current location of the target vehicle 10 and transmit it to the driver 2.

(2) Further, as shown in FIG. 11, the target vehicle 10 may be provided with a traveling road determination device 12 for detecting that the traveling road has been switched between a general road and an expressway. .. In this case, the road information de indicating whether the traveling road of the target vehicle 10 at the time when each monitoring information (d1, d2) is transmitted from each monitoring device (20, 30) to the server 60 is a general road or an expressway. However, it may be transmitted at the same time. The driving road determination device 12 is composed of, for example, an automatic toll collection system (ETC) mounted on the target vehicle 10. According to this configuration, the road information de of the target vehicle 10 at the time when each warning condition is satisfied can be associated with each monitoring information (d1 and d2) and stored in the storage unit 62 of the server 60.

The road information de is transmitted from the driving road determination device 12 to each monitoring device (20, 30), and then from each monitoring device (20, 30) to the server 60 together with each monitoring information (d1, d2). It does not matter if it is transmitted. As another method, when each monitoring information (d1, d2) is transmitted from each monitoring device (20, 30) to the server 60, the road information de from the traveling road determination device 12 to the server 60. May be sent.

Further, as another method, the driving road determination device 12 may periodically transmit the road information de to the server 60 at predetermined time intervals. In this case, the server 60 stores the road information de in the storage unit 62, and at the time when each monitoring information (d1, d2) transmitted from each monitoring device (20, 30) is received, the nearest time is reached. The road information de transmitted to may be read from the storage unit 62.

The storage unit 62 of the server 60 stores in advance the monitoring determination conditions depending on whether the road on which the target vehicle 10 travels is a general road or an expressway. For example, under the conditions exemplified in FIG. 6, depending on whether the road on which the target vehicle 10 travels is a general road or a highway, the monitoring target occurrence time interval, the occurrence number threshold value, and / or the first monitoring information d1 and the second The conditions for the combination of the monitoring information d2 can be different. As a result, the accuracy of determining whether or not the driving state of the driver 2 is highly dangerous is further improved based on the monitoring required determination conditions suitable for the characteristics of the road on which the target vehicle 10 travels. In this case, in step S33, the server 60 may transmit the road information de together with the monitoring notification information da to the administrator terminal 80.

In the example shown in FIG. 11, the target vehicle 10 is provided with the position information detection device 11 together with the driving road determination device 12, but it is also possible to configure the target vehicle 10 without the position information detection device 11. be.

[Second Embodiment]
The second embodiment of the management support system according to the present invention will be mainly described with respect to the parts different from the first embodiment. FIG. 12 is a block diagram schematically showing the overall configuration of the management support system according to the present embodiment. The management support system 1 of the present embodiment is different in that the server 60 includes the correction processing unit 65. The correction processing unit 65 is an arithmetic processing unit that performs predetermined signal processing (calculation) based on the acquired information, and is composed of dedicated software and / or hardware.

The management support system 1 shown in FIG. 12 shows a case where the target vehicle 10 is provided with the position information detecting device 11 and the driving road determination device 12, but is not provided with these devices (11, 12). It may be configured.

In the present embodiment, the driver 2 performs information acquisition processing regarding the physical condition state (pre-driving physical condition state) before driving the target vehicle 10. As this information, for example, the body temperature, blood pressure, autonomic nerve, pulse wave, heart rate, blood oxygen concentration, etc. of the driver 2 can be used. These devices for measuring the pre-driving physical condition of the driver 2 are hereinafter referred to as "pre-driving physical condition measuring devices". This pre-driving physical condition measuring device may be permanently installed in a business office where the target vehicle 10 is parked, or may be mounted on each target vehicle 10. Further, the pre-driving physical condition measuring device may be a single device or a plurality of device groups.

When the pre-driving physical condition measuring device measures various biological signals before the driving of the driver 2, the biological signal is transmitted to the server 60. The server 60 stores various biological signals before the operation of the driver 2 in the storage unit 62. That is, the pre-driving physical condition measuring device is configured to enable wireless communication with the server 60. In addition, at least, as long as various biological signals measured by the pre-driving physical condition measuring device can be transmitted to the server 60, the pre-driving physical condition measuring device does not necessarily have to be provided with the communication means.

Various past biological signals of the driver 2 are stored in the storage unit 62 of the server 60. Further, the tendency of various biological signals or biological signals before and after the past driving of the driver 2 may be stored. The correction processing unit 65 reads various biological signals of the driver 2 from the storage unit 62, and determines the physical condition state of the driver 2 at the present time (hereinafter, referred to as “pre-driving physical condition state”). For example, when the body temperature of the driver 2 transmitted before driving is 2 ° C. or more higher than the past average body temperature of the driver 2, it is determined that the pre-driving physical condition of the driver 2 is a state requiring attention. Further, as another example, the state of the autonomic nerve of the driver 2 transmitted before driving is evaluated based on the conditions in the table shown in FIG. 13, and the state of physical condition before driving of the driver 2 is a state requiring attention. Judge whether or not. Further, as another example, the tendency of the biological signal after driving is predicted from the biological signal before driving, and it is determined whether or not the physical condition before driving is a caution state.

In FIG. 13, "LF" corresponds to an index reflecting a sympathetic nerve, and "HF" corresponds to an index reflecting a parasympathetic nerve. Further, the deviation value Ti is a value obtained by correcting a value (TP) indicating the function of the entire autonomic nerve function by the heart rate (ccvTP) and converting it into a deviation value according to the age of the driver 2. Each of the LF, HF, and deviation value Ti shown in FIG. 13 is corrected based on the values of biological signals such as the pulse wave and heartbeat of the driver 2 measured by the pre-driving physical condition measuring device. It can be calculated by arithmetic processing. It is assumed that the storage unit 62 of the server 60 stores information about the age of each driver 2.

For example, when the correction processing unit 65 determines that the pre-driving physical condition of the driver 2 is "need attention", the correction processing unit 65 corrects the monitoring determination condition of the driver 2 stored in the storage unit 62. .. As an example, as shown in FIG. 14, the following condition 5 is added to the example of FIG.

(5) Condition 5: Even one of the following conditions is satisfied. The values n ₁ , n ₂ , and n ₃ are appropriately set according to the past tendency of the driver 2.
The server 60 has the first monitoring information d1 indicating the determination values 1-1, 1-2, 1-3, 1-4, 1-5, or 1-6 within the past 10 minutes including the current time. Has been received _n times or more.
-The server 60 has received the first monitoring information d1 indicating the determination value 2-2 or _2-3 n times or more within the past 10 minutes including the current time.
-The server 60 receives the second monitoring information d2 indicating the determination values 3-5, 3-6, 3-7, or _3-8 n3 times or more within the past 10 minutes including the current time. There is.

By adding this condition 5, the "monitoring-required determination condition", which is a reference when the determination processing unit 63 determines, becomes stricter. That is, when the server 60 receives each monitoring information (d1, d2) transmitted from each monitoring device (20, 30), the probability of determining YES in step S32 increases. That is, the conditions for transmitting the monitoring notification information da to the administrator terminal 80 have become stricter, and the administrator has focused more on the driver 2 whose pre-driving physical condition is determined to require attention. Can be managed.

The values of n ₁ , n _2, and n ₃ in FIG. 14 may be appropriately set according to the pre-driving physical condition of the driver 2, or may be predetermined values. I do not care.

[Another Embodiment]
Hereinafter, another embodiment will be described.

<1> The determination processing unit 63 of the server 60 determines how much the operating state of the driver 2 is relative to the monitoring required level based on the monitoring information (d1, d2) transmitted from each monitoring device (20, 30). It may be possible to create monitoring-required proximity information indicating whether or not the vehicle is approaching. For example, in the storage unit 62 of the server 60, the first monitoring information d1 corresponding to any of the determination values 1-1, 1-2, 1-5 in the past 20 minutes is input from the target vehicle 10 driven by the driver 2. It is assumed that the fact that the message has been received 22 times is stored. In this case, the determination processing unit 63 of the server 60 recognizes that the operating state of the driver 2 reaches the monitoring required level if the equivalent first monitoring information d1 is received eight times over the next 10 minutes.

In such a case, for example, the server 60 transmits the monitoring required proximity information to the smartphone owned by the driver 2, so that the monitoring required proximity information as shown in FIG. 15, for example, is imaged on the screen of the smartphone. It may be used to display the converted information. In the example of FIG. 15, the evaluation of the operating state of the driver 2 at the present time is evaluated based on the difference between the number of occurrences corresponding to each monitoring information (d1 and d2) and the threshold value of the number of occurrences set in advance in the monitoring required determination condition. , Displayed as a score. In this example, the score 100 is the case where the number of occurrences of the target monitoring information (d1, d2) reaches the threshold value within the monitoring target occurrence time interval specified in the monitoring required judgment condition, and the current number of occurrences is the threshold value. It is a score display of how close they are.

The driver 2 can visually recognize his / her own driving state at the present time by checking the image information displayed on the smartphone, for example, when the vehicle is stopped.

<2> In the above embodiment, each monitoring device (20, 30) has been described as transmitting each warning signal (d1, d2) to the server 60 when it detects that each warning condition has been reached. .. At this time, each monitoring device (20, 30) has image information related to the acceleration of the target vehicle 10 with respect to the server 60, the proximity state to the obstacle in front (vehicle, pedestrian, etc.), and the driver 2. Raw data such as information related to the pulse wave of the above may be transmitted together. Further, even when each warning condition is not reached, the information detected by each monitoring device (20, 30) may be periodically transmitted to the server 60.

As a result, in the storage unit 62 of the server 60, information related to the driving state and the physical condition of the driver 2 in normal times is accumulated, so that it is possible to set the monitoring determination condition considering the characteristics of each driver 2. This makes it possible, and the accuracy of determining whether or not the driving state of the driver 2 is high in danger is further improved.

<3> The first monitoring device 20 and / or the second monitoring device 30 may be configured to include two or more types of devices, respectively. For example, the means (transmitters 24, 34) for realizing wireless communication in each monitoring device (20, 30) may be configured by a terminal device for wireless communication (for example, a smartphone or a personal computer). Of course, the same replacement / change is possible for other configurations.

<4> The above-mentioned warning conditions and monitoring-required determination conditions are merely examples, and the present invention is not limited to this content. For example, when the first monitoring device 20 mounted on the target vehicle 10 is equipped with a speed sensor and detects that the speed of the target vehicle 10 is traveling at an extremely dangerous high speed, information to that effect is transmitted to the server 60. It is possible that the server 60 immediately notifies the administrator terminal 80 of the monitoring notification information. Further, as another example, the target vehicle 10 is provided with a time measuring device for measuring the continuous traveling time of the target vehicle 10, and when it is detected that the target vehicle 10 is continuously traveling for a predetermined time or longer, that effect. The information can be transmitted to the server 60, and the monitoring notification information can be immediately notified from the server 60 to the administrator terminal 80.

<5> In the above embodiment, it has been described that the first monitoring device 20 and the second monitoring device 30 output a warning signal in the target vehicle 10 when they detect that each warning condition is reached. However, in the present invention, the first monitoring device 20 and the second monitoring device 30 may be configured to be capable of outputting a warning signal in the target vehicle 10, and may not necessarily actually output the warning signal.

<6> The present invention is not limited to the above-described embodiment, and includes various modifications. For example, the embodiments described above have been described in detail for a better understanding of the present invention and are not necessarily limited to those comprising all the configurations of the description. The scope of the present invention is indicated by the scope of claims and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
