It is also possible to classify the health status of crew members into three or more levels, such as a state where they can work without conditions, a state where they can work with conditions, and a state where they cannot work, instead of two levels, a state where they can work and a state where they cannot work, based on the measured values of the crew members' health status, such as their blood pressure, pulse rate, and body temperature. In this case, it is necessary to set the threshold value for judging the health status of the crew members at smaller intervals than when the health status of the crew members is judged in two levels, a state where they can work and a state where they cannot work. In contrast, the measured values of the crew members' health status, such as their blood pressure, vary depending on the individual crew members. Therefore, for example, the health status of a crew member whose blood pressure is consistently high and stable may be erroneously judged to be one level worse, even though his or her blood pressure is normal.

In view of the above circumstances, the present invention aims to provide a driver determination device and a traffic management system that can determine the health status of drivers while taking into account individual differences.

The present invention will be described below in accordance with a preferred embodiment. Note that the present invention is not limited to the embodiment described below, and can be modified as appropriate without departing from the spirit of the present invention. In addition, in the embodiment described below, some configurations are omitted from illustration and description, but for the details of the omitted technology, publicly known or well-known technology is applied as appropriate within the scope of not causing any inconsistencies with the contents described below.

Figure 1 is a conceptual diagram of a traffic management system 1 according to one embodiment of the present invention. The traffic management system 1 shown in this figure is a system for preventing accidents caused by the health condition of a driver C who drives a truck T and realizing safe operation of the truck T. This traffic management system 1 includes a PC (personal computer) 10, a measurement device 20, a server 30, an in-vehicle device 40, and a wearable measurement device 50. The PC 10 is connected to the server 30 via an Internet network I, and the server 30 is connected to the in-vehicle device 40 via a wide area communication network W. In addition, the measurement device 20 is connected to the PC 10 by wire or wirelessly, and the wearable measurement device 50 is connected to the in-vehicle device 40 by wirelessly.

PC 10 is installed in an office for managing the operation of truck T and for taking roll calls of crew members C, and is operated by the operations manager M. This PC 10 has a crew member determination function. This crew member determination function determines the health condition of crew member C into three stages: a state in which the driver is able to drive without driving conditions, a state in which the driver is able to drive with driving conditions, and a state in which the driver is prohibited from driving, based on numerical information, which is a measurement value related to the health condition of crew member C measured by the measurement device 20, and reported information related to the health condition of crew member C input by the operations manager M.

Examples of the numerical information include crew member C's blood pressure, pulse rate, and body temperature. The reported information is information obtained from crew member C during roll call. Examples of the reported information from crew member C include whether or not crew member C is visiting a hospital, whether or not crew member C is taking medication, whether or not crew member C who is taking medication has forgotten to take their prescribed medicine, etc.

When the PC 10 judges that the health condition of the crew member C is such that he or she can work without any driving conditions, the PC 10 transmits roll call information stating "Can work without driving conditions" to the vehicle-mounted device 40 via the Internet network I, etc. Also, when the PC 10 judges that the health condition of the crew member C is such that he or she can work with driving conditions, the PC 10 transmits roll call information stating "Can work with driving conditions" to the vehicle-mounted device 40 via the Internet network I, etc.

Schedule information such as the operation schedule of truck T and the driving schedule of crew member C is input to PC 10 by the operation of operations manager M. PC 10 transmits the input schedule information to server 30 via Internet network I.

The measuring device 20 is installed in the office where the PC 10 is installed, and is connected to the PC 10 by wire or wirelessly. This measuring device 20 measures, for example, the blood pressure, pulse, and body temperature of the crew member C, and transmits the measured values to the PC 10. The PC 10 transmits the numerical information of the blood pressure, pulse, and body temperature of the crew member C received from the measuring device 20 to the server 30 via the Internet network I.

The server 30 stores in the memory unit 31 the numerical information of the driver C, such as the blood pressure, pulse, and body temperature, received from the PC 10, in association with the identification information of the driver C and the time information at the time of information acquisition (measurement). The server 30 also stores in the memory unit 31 schedule information, such as the operation schedule of the truck T and the driving schedule of the driver C, received from the PC 10.

The wearable measurement device 50 is worn by the crew member C while on duty, and measures the blood pressure, pulse rate, body temperature, etc. of the crew member C while on duty and transmits the measured values to the vehicle-mounted device 40. The vehicle-mounted device 40 judges the health condition of the crew member C based on the numerical information of the blood pressure, pulse rate, body temperature, etc. of the crew member C received from the wearable measurement device 50. The vehicle-mounted device 40 transmits the judgment result of the health condition of the crew member C to the PC 10.

When the vehicle-mounted device 40 receives health condition information from the PC 10 indicating that the driver is "available for driving under certain conditions," the vehicle-mounted device 40 periodically displays information regarding the driving conditions on the monitor 46 (see FIG. 3) provided on the vehicle-mounted device 40. Examples of the driving conditions include "promoting abstinence from smoking while driving," "being warned about taking sufficient rests," and "being warned about loading and unloading work." Examples of "sufficient rest" include limiting continuous driving to three hours and taking a one-hour break along the way. Furthermore, examples of "warnings about loading and unloading work" include limiting high-intensity work and recommending that a worker accompany the driver.

After the operation is completed, the vehicle-mounted device 40 transmits operation data to the PC 10. After the operation is completed, the operation manager M conducts a roll call of the driver C who has finished driving. If the PC 10 does not receive a determination from the vehicle-mounted device 40 that the driver C is prohibited from driving while on duty, it displays a message on the monitor 46 encouraging health management.

On the other hand, if the PC 10 receives from the vehicle unit 40 a determination result that the driver C is prohibited from driving while on duty, it displays on the monitor a selection screen for the driver C to select whether or not to take an extra day off. The operations manager M selects whether or not the driver C will take an extra day off based on the driver C's declaration. If the operations manager M operates the PC 10 to select that the driver C will take an extra day off, the PC 10 executes a substitute driver selection process to select a substitute driver and update the operation schedule. On the other hand, if the operations manager M operates the PC 10 to select that the driver C will not take an extra day off, the PC 10 displays on the monitor the health management items that should be carried out in advance before the driver C comes to work next time.

Figure 2 is a block diagram showing the functions of the CPU (Central Processing Unit) 11 of the PC 10 shown in Figure 1. As shown in this figure, the CPU 11 has a driver determination unit 110 and an operation management unit 120. The driver determination unit 110 has an acquisition unit 111, a setting unit 112, and a determination unit 113.

During the pre-duty roll call process, the acquisition unit 111 acquires the above-mentioned numerical information indicating the health condition of the crew member C measured by the measurement device 20 from the measurement device 20 and stores it in the memory unit 31 of the server 30 (see FIG. 1). The acquisition unit 111 also acquires the above-mentioned reported information of the crew member C entered into the PC 10 by the operation of the operations manager M and stores it in the memory unit 31 of the server 30.

The setting unit 112 sets a judgment condition for judging the health state of the crew member C based on the numerical information of the crew member C acquired by the acquisition unit 111 and the numerical information of the crew member C stored in the memory unit 31 of the server 30. In this embodiment, the setting unit 112 sets a judgment condition for judging the health state of the crew member C by dividing it into a state in which the crew member C can work without a work condition and a state in which the crew member can work with a work condition based on the numerical information of the crew member C acquired by the acquisition unit 111 at the current roll call and the numerical information of the crew member C acquired by the acquisition unit 111 at the previous roll call (e.g., the day before) and stored in the memory unit 31. In this embodiment, the setting unit 112 sets a judgment condition for judging the health state of the crew member C by dividing it into a state in which the crew member C can work with a work condition and a state in which the crew member C cannot work based on the numerical information of the crew member C acquired by the acquisition unit 111 at the current roll call and the report information of the crew member C acquired by the acquisition unit 111 at the current roll call.

The determination unit 113 determines the health condition of the crew member C based on the determination conditions set by the setting unit 112. In this embodiment, the determination unit 113 determines the health condition of the crew member C based on the determination conditions set by the setting unit 112, dividing the health condition of the crew member C into three stages: a state in which the crew member C can work without any driving conditions, a state in which the crew member can work with driving conditions, and a state in which the crew member C is prohibited from working. The determination unit 113 transmits the determination result to the operation management unit 120.

The operation management unit 120 includes a monitoring unit 121, a crew member selection unit 122, a schedule generation unit 123, and a notification unit 124. When the determination unit 113 determines in the pre-drive roll call process that the health state of the crew member C is such that the crew member can drive without any driving conditions, or such that the crew member can drive with driving conditions, the monitoring unit 121 transmits the determination result to the vehicle-mounted device 40. In addition, when the monitoring unit 121 receives a determination result from the vehicle-mounted device 40 in the on-drive monitoring process that the health state of the crew member C is such that the crew member cannot drive, the monitoring unit 121 displays the received determination result on the monitor of the PC 10.

When the determination unit 113 determines in the pre-drive roll call process that the health condition of the crew member C is such that they are prohibited from driving, and when the crew member selection unit 122 receives a determination result from the on-board device 40 that the health condition of the crew member C is such that they are prohibited from driving, the crew member selection unit 122 reads out a list of replaceable crew members from the memory unit 31 of the server 30 and displays it on the monitor. The operation manager M performs an operation to select the crew member C from the list displayed on the monitor. The crew member selection unit 122 selects the crew member C selected by the operation of the operation manager M as a replacement crew member.

In addition, when the crew selection unit 122 receives a determination result from the on-board device 40 during the post-duty roll call process that the health condition of the on-duty crew C is prohibited from driving while the on-duty monitoring process is being executed, the crew selection unit 122 displays a selection screen on the monitor of the PC 10 for the crew C to select whether or not to take an extra day off. When the operation manager M selects that the crew C will take an extra day off, the crew selection unit 122 reads a list of replaceable crew C from the storage unit 31 of the server 30 and displays it on the monitor of the PC 10. The operation manager M selects the crew C from the list displayed on the monitor of the PC 10. The crew selection unit 122 selects the crew C selected by the operation of the operation manager M as a substitute crew member. When a substitute crew member is selected by the crew selection unit 122, the schedule generation unit 123 updates the operation schedule to reflect the replacement of the crew member C.

The notification unit 124 displays a notification on the monitor of the PC 10 when it receives a determination result from the vehicle-mounted device 40 that the health condition of the on-duty crew C is prohibited from driving while the on-duty monitoring process is being executed. In addition, when the notification unit 124 does not receive a determination result from the vehicle-mounted device 40 that the health condition of the on-duty crew C is prohibited from driving while the on-duty monitoring process is being executed, it displays a message promoting health management on the monitor in the post-duty roll call process. On the other hand, when the notification unit 124 receives a determination result from the vehicle-mounted device 40 that the health condition of the on-duty crew C is prohibited from driving while the on-duty monitoring process is being executed during the post-duty roll call process, and a substitute crew member is not selected by the crew member selection unit 122, it displays on the monitor of the PC 10 the health management items to be performed in advance before the next shift.

Figure 3 is a block diagram showing the hardware configuration of the vehicle-mounted device 40 shown in Figure 1. The vehicle-mounted device 40 shown in this figure is mounted in the driver's seat of a truck T. This vehicle-mounted device 40 includes a CPU 41, a ROM (Read Only Memory) 42, a RAM (Random Access Memory) 43, a recording medium 44, an input unit 45, a monitor 46, a speaker 47, and an antenna 48.

The CPU 41 reads out a control program stored in the ROM 42 into the RAM 43 and executes various control and calculation processes. In this embodiment, the CPU 41 executes a process of authenticating the crew member C, a process of displaying or sounding a message for the crew member C, and a process of judging the health condition of the crew member C and transmitting the judgment result. The CPU 41 receives inputs of the vehicle speed, engine RPM, position information from the Global Positioning System (GPS), analog signals, external input signals, output signals from the wearable measurement device 50, switch input signals from the input unit 45, etc.

The recording medium 44 is an external recording device such as an SD card. The input unit 45 is an input device such as a switch or a touch panel. The monitor 46 is a display device that displays various information such as messages for the crew C. The speaker 47 is a device that sounds various information such as messages for the crew C.

The antenna 48 includes an antenna for wide-area communication, an antenna for communication with the wearable measurement device 50, and an antenna for communication with GPS satellites. The antenna for wide-area communication communicates with the server 30 via the wide-area communication network W. The antenna for communication with the wearable measurement device 50 is a transmitting antenna compatible with short-range wireless technology such as Bluetooth (registered trademark), and receives numerical information indicating the health condition of the crew member C measured by the wearable measurement device 50. The antenna for communication with GPS satellites receives signals from GPS satellites.

Figure 4 is a flowchart for explaining the pre-duty roll call processing and on-duty monitoring processing of the PC 10 shown in Figure 2. Also, Figure 5 is a flowchart for explaining the pre-duty roll call processing and substitute crew selection processing of the PC 10 shown in Figure 2. As shown in these flowcharts, first, in step 1, the acquisition unit 111 determines whether or not numerical information indicating the health condition of the crew member C has been received from the measurement device 20. In this embodiment, the numerical information is a blood pressure value. If a positive determination is made in step 1, the process proceeds to step 2, and step 1 is repeatedly executed while a negative determination is made in step 1.

In step 2, the acquisition unit 111 stores the numerical information received from the measurement device 20 in the memory unit 31 of the server 30. Except when the crew member C is receiving a roll call for the first time, the memory unit 31 of the server 30 stores the numerical information of the crew member C previously acquired. The process moves from step 2 to step 3.

In step 3, the setting unit 112 determines whether the currently acquired numerical information of the crew member C is less than the first threshold value. In this embodiment, the numerical information is a blood pressure value, and the first threshold value is 140 mmHg for the upper limit and 90 mmHg for the lower limit. If a positive determination is made in step 3, the process proceeds to step 8, and if a negative determination is made in step 3, the process proceeds to step 4.

In step 4, the setting unit 112 determines whether the currently acquired numerical information of the crew member C is less than the second threshold value. In this embodiment, the numerical information is a blood pressure value, and the second threshold value is 160 mmHg on the upper side and 100 mmHg on the lower side. If a positive determination is made in step 4, the process proceeds to step 5, and if a negative determination is made in step 4, the process proceeds to step 6 in FIG. 5.

In step 5 of FIG. 4, the setting unit 112 determines whether the previously acquired numerical information of the crew member C is less than the first threshold value. If a negative determination is made in step 5, the process proceeds to step 8, and if a positive determination is made in step 5, the process proceeds to step 9.

In step 6 of FIG. 5, the setting unit 112 determines whether the currently acquired numerical information of the crew member C is less than the third threshold value. In this embodiment, the numerical information is a blood pressure value, and the third threshold value is 180 mmHg for the upper limit and 110 mmHg for the lower limit. If a positive determination is made in step 6, the process proceeds to step 7, and if a negative determination is made in step 6, the process proceeds to step 10.

In step 7, the setting unit 112 determines whether the currently acquired reported information of the crew member C satisfies a predetermined condition. In this embodiment, the predetermined condition is that the crew member C is not visiting a hospital, or that the crew member C is undergoing medical treatment but has forgotten to take his/her medicine. If a negative determination is made in step 7, the process proceeds to step 9 in FIG. 4, and if a positive determination is made in step 7, the process proceeds to step 10 in FIG. 5.

In step 8 of FIG. 4, the judgment unit 113 judges that the health state of the crew member C is such that they are capable of flying without any flying conditions. The process moves from step 8 to step 11. In addition, in step 9, the judgment unit 113 judges that the health state of the crew member C is such that they are capable of flying with flying conditions. The process moves from step 9 to step 12. Furthermore, in step 10 of FIG. 5, the judgment unit 113 judges that the health state of the crew member C is such that they are prohibited from flying. The process moves from step 10 to step 13.

In other words, based on the current measurement value, the previous measurement value, and the declared information, the setting unit 112 sets a first condition for determining that the health state of the crew member C is such that they can work without any driving conditions, a second condition for determining that the health state of the crew member C is such that they can work with driving conditions, and a third condition for determining that the health state of the crew member C is such that they cannot work.

Here, the first condition is that the current measurement value is less than the first threshold, or that the current and previous measurement values are equal to or greater than the first threshold and less than the second threshold (>first threshold). The second condition is that the current measurement value is equal to or greater than the first threshold and less than the second threshold, and the previous measurement value is less than the first threshold, or that the current measurement value is equal to or greater than the second threshold and less than the third threshold (>second threshold), and the reported information of the crew member C does not satisfy the predetermined prohibition condition. The third condition is that the current measurement value is equal to or greater than the third threshold, or that the current measurement value is equal to or greater than the second threshold and less than the third threshold, and the reported information of the crew member C satisfies the predetermined prohibition condition.

In step 11 of FIG. 4, the monitoring unit 121 transmits to the vehicle-mounted device 40 the determination result that the health state of the crew member C is such that the crew member is able to work without any driving conditions. The process proceeds from step 11 to step 15. In addition, in step 12, the monitoring unit 121 transmits to the vehicle-mounted device 40 the determination result that the health state of the crew member C is such that the crew member is able to work with driving conditions. The process proceeds from step 12 to step 15.

In step 13 of FIG. 5, the crew selection unit 122 reads out a list of replaceable crew members from the memory unit 31 of the server 30 and displays it on the monitor. The process proceeds from step 13 to step 14. In step 14, the crew selection unit 122 determines whether a replacement crew member has been selected from the list by operating the PC 10. If a positive determination is made in step 14, the process proceeds to step 1, and step 14 is repeatedly executed while a negative determination is made in step 14. If a replacement crew member has been selected, a pre-duty roll call process is executed again for the replacement crew member.

Figure 6 is a flowchart for explaining the on-duty monitoring process of the on-board device 40 shown in Figure 1. In this on-duty monitoring process, first, in step 101, the CPU 41 of the on-board device 40 determines whether or not a determination result has been received from the PC 10 (CPU 11) that the health state of the crew member C is such that he or she is able to work under the conditions of working. If a positive determination is made in step 101, the process proceeds to step 103, and if a negative determination is made in step 101, the process proceeds to step 102.

In step 102, the CPU 41 judges whether or not a judgment result that the health condition of the crew member C is such that the crew member C is able to work without any driving conditions has been received from the PC 10 (CPU 11). If a positive judgment is made in step 102, the process proceeds to step 103, and if a negative judgment is made in step 102, the process proceeds to step 101.

In step 103, the CPU 41 determines whether or not the truck T has started operating (whether or not the truck T has left the warehouse) based on the position information, speed information, etc. If a positive determination is made in step 103, the process proceeds to step 104, and step 103 is repeatedly executed while a negative determination is made in step 103.

In step 104, the CPU 41 determines whether or not the truck T has started traveling based on the position information, speed information, etc. If a positive determination is made in step 104, the process proceeds to step 105, and step 104 is repeatedly executed while a negative determination is made in step 104.

In step 105, the CPU 41 determines whether or not numerical information indicating the health condition of the crew member C (blood pressure value in this embodiment) has been received from the wearable measurement device 50. If a positive determination is made in this step, the process proceeds to step 106, and if a negative determination is made in this step, the process proceeds to step 108.

In step 106, the CPU 41 determines whether the health condition of the driver C is such that the driver C is prohibited from driving based on the numerical information received from the wearable measurement device 50. If a positive determination is made in step 106, the process proceeds to step 107, and if a negative determination is made in step 106, the process proceeds to step 105.

In step 107, the CPU 41 transmits to the PC 10 the result of the determination that the health condition of the driver C is such that he or she is prohibited from driving. The process proceeds from step 107 to step 109.

On the other hand, in step 108, the CPU 41 displays on the monitor 46 or sounds from the speaker 47 a message presenting information about the driving conditions or checking the physical condition of the driver C at predetermined time intervals. The process proceeds from step 108 to step 109.

In step 109, the CPU 41 determines whether the operation of the truck T has ended (whether the truck T has entered the warehouse) based on the position information, speed information, etc. If a positive determination is made in step 109, the process proceeds to step 110, and if a negative determination is made in step 109, the process proceeds to step 105.

In step 110, the CPU 41 transmits operation data, which is information about the current operation of the truck T, to the PC 10. This ends the on-board monitoring process of the vehicle-mounted device 40.

In response to this, the PC 10 executes on-duty monitoring processing in steps 15 to 17 of FIG. 4. First, in step 15, the monitoring unit 121 determines whether or not operation data has been received from the CPU 41. If a positive determination is made in step 15, the process proceeds to step 201 in FIG. 7, and if a negative determination is made in step 15, the process proceeds to step 16 in FIG. 4.

In step 16, the monitoring unit 121 judges whether or not it has received a judgment result from the CPU 41 that the health condition of the driver C is such that he or she is prohibited from driving. If a positive judgment is made in step 16, the process proceeds to step 17, and if a negative judgment is made in step 16, the process proceeds to step 15.

In step 17, the notification unit 124 displays on the monitor the result of the determination that the health condition of the crew member C is such that he or she is prohibited from driving. The process proceeds from step 17 to step 15.

Figure 7 is a flowchart for explaining the post-duty roll call processing of the PC 10 shown in Figure 1. In this post-duty roll call processing, first, in step 201, the crew selection unit 122 determines whether or not a determination result has been received from the vehicle-mounted device 40 while the on-duty monitoring processing is being executed that the health condition of the on-duty crew C is in a state where driving is prohibited. If a negative determination is made in step 201, the process proceeds to step 202, and if a positive determination is made in step 201, the process proceeds to step 203.

In step 202, the notification unit 124 displays a message on the monitor to encourage health management. After step 202, the post-duty roll call process ends.

On the other hand, in step 203, the crew selection unit 122 displays on the monitor a selection screen for the crew C to select whether or not to take an extra day off. The process proceeds from step 203 to step 204. In step 204, the crew selection unit 122 determines whether or not the crew C has selected to take an extra day off. If a negative determination is made in step 204, the process proceeds to step 205, and if a positive determination is made in step 204, the process proceeds to step 206.

In step 205, the notification unit 124 displays on the monitor the health management items that should be performed in advance before the next shift. After step 205, the post-shift roll call process ends.

On the other hand, in step 206, the crew selection unit 122 displays a list of replaceable crew members C on the monitor. The process proceeds from step 206 to step 207. In step 207, the crew selection unit 122 determines whether or not a replaceable crew member C has been selected from the list. If a positive determination is made in step 207, the process proceeds to step 208, and step 207 is repeatedly executed while a negative determination is made in step 207.

In step 208, the crew selection unit 122 selects the crew member selected by operating the PC 10 as a replacement crew member. The process proceeds from step 208 to step 209. In step 209, the schedule generation unit 123 updates the operation schedule to reflect the replacement of the crew member with the replacement crew member selected by the crew selection unit 122. After step 209, the post-duty roll call process is terminated.

Figure 8 is a flowchart for explaining another embodiment of the pre-duty roll call processing of the PC 10 shown in Figure 4. Also, Figure 9 is a flowchart for explaining another embodiment of the pre-duty roll call processing and substitute crew selection processing of the PC 10 shown in Figure 5. As shown in the flowchart in Figure 8, first, in step 301, the acquisition unit 111 determines whether or not numerical information indicating the health condition of the crew member C has been received from the measurement device 20. In this embodiment, the numerical information is a pulse value. If a positive determination is made in step 301, the process proceeds to step 302, and step 301 is repeatedly executed while a negative determination is made in step 301.

In step 302, the acquisition unit 111 stores the numerical information received from the measurement device 20 in the memory unit 31 of the server 30. Except when the crew member C is receiving a roll call for the first time, the memory unit 31 of the server 30 stores the numerical information of the crew member C previously acquired. The process proceeds from step 302 to step 303.

In step 303, the setting unit 112 determines whether the currently acquired numerical information of the crew member C is within the range of the first threshold value. In this embodiment, the numerical information is a pulse value, and the first threshold value is 60 beats/minute or more and 90 beats/minute or less. If a positive determination is made in step 303, the process proceeds to step 308, and if a negative determination is made in step 303, the process proceeds to step 304.

In step 304, the setting unit 112 determines whether the currently acquired numerical information of the crew member C is within the range of the second threshold. In this embodiment, the numerical information is a pulse value, and the second threshold is 51 beats/min or more and 59 beats/min or less, or 91 beats/min or more and 99 beats/min or less. If a positive determination is made in step 304, the process proceeds to step 305, and if a negative determination is made in step 304, the process proceeds to step 306 in FIG. 9.

In step 305 of FIG. 8, the setting unit 112 determines whether the previously acquired numerical information of the crew member C is within the range of the first threshold value. If a negative determination is made in step 305, the process proceeds to step 308, and if a positive determination is made in step 305, the process proceeds to step 309.

In step 306 of FIG. 9, the setting unit 112 determines whether the currently acquired numerical information of the crew member C is within the range of the third threshold value. In this embodiment, the numerical information is a pulse value, and the third threshold value is 50 beats/minute or less, or 100 beats/minute or more. If a positive determination is made in step 306, the process proceeds to step 307, and if a negative determination is made in step 306, the process proceeds to step 310.

The processing of steps 307 to 310, 313, and 314 is the same as the processing of steps 7 to 10, 13, and 14 in the above embodiment, so the explanation of the processing of steps 7 to 10, 13, and 14 in the above embodiment is used. Note that the pre-boarding roll call processing of this embodiment may be performed instead of the pre-boarding roll call processing of the above embodiment, and both the pre-boarding roll call processing of this embodiment and the pre-boarding roll call processing of the above embodiment may be performed.

Figure 10 is a flowchart for explaining another embodiment of the pre-duty roll call processing of the PC 10 shown in Figure 4. Also, Figure 11 is a flowchart for explaining another embodiment of the pre-duty roll call processing and substitute crew selection processing of the PC 10 shown in Figure 5. As shown in these flowcharts, first, in step 401, the acquisition unit 111 determines whether or not numerical information indicating the health condition of crew member C has been received from the measurement device 20. In this embodiment, the numerical information is a body temperature value. If a positive determination is made in step 401, the process proceeds to step 402, and step 401 is repeatedly executed while a negative determination is made in step 401.

In step 402, the acquisition unit 111 stores the numerical information received from the measurement device 20 in the memory unit 31 of the server 30. Except when the crew member C is receiving a roll call for the first time, the memory unit 31 of the server 30 stores the numerical information of the crew member C previously acquired. The process proceeds from step 402 to step 403.

In step 403, the setting unit 112 determines whether the currently acquired numerical information of the crew member C is less than the first threshold value. In this embodiment, the numerical information is a body temperature value, and the first threshold value is 37.5°C. If a positive determination is made in step 403, the process proceeds to step 408, and if a negative determination is made in step 403, the process proceeds to step 404.

In step 404, the setting unit 112 determines whether the currently acquired numerical information of the crew member C is equal to or lower than the second threshold value. In this embodiment, the numerical information is a body temperature value, and the second threshold value is 37.9°C. If a positive determination is made in step 404, the process proceeds to step 405, and if a negative determination is made in step 404, the process proceeds to step 406 in FIG. 11.

In step 405 of FIG. 10, the setting unit 112 determines whether the currently acquired numerical information of the crew member C is equal to or greater than the average value of the previously acquired numerical information of the crew member C plus 0.5°C. If a negative determination is made in step 405, the process proceeds to step 408, and if a positive determination is made in step 405, the process proceeds to step 409.

In step 406 of FIG. 11, the setting unit 112 determines whether the currently acquired numerical information of crew member C is less than the third threshold value. In this embodiment, the numerical information is a body temperature value, and the third threshold value is 38.0°C. If a positive determination is made in step 406, the process proceeds to step 407, and if a negative determination is made in step 406, the process proceeds to step 410.

The processing of steps 407 to 410, 413, and 414 is the same as the processing of steps 7 to 10, 13, and 14 in the above embodiment, so the explanation of the processing of steps 7 to 10, 13, and 14 in the above embodiment is used. Note that the pre-boarding roll call processing of this embodiment may be implemented in place of the pre-boarding roll call processing of the above embodiment or example, and all of the pre-boarding roll call processing of this embodiment, the pre-boarding roll call processing of the above embodiment, and the boarding roll call processing of the above example may be implemented.

As described above, according to the operation management system 1 of this embodiment, the health condition of the crew member C is judged not in two stages, a state in which the crew member is able to drive and a state in which the crew member is prohibited from driving, but in three or more stages, such as a state in which the crew member is able to drive without driving conditions, a state in which the crew member is able to drive with driving conditions, and a state in which the crew member is prohibited from driving. In the process of judging the health condition of the crew member C, the setting unit 112 of the CPU 11 sets judgment conditions for judging the health condition of the crew member C based not only on the health condition information of the crew member C acquired this time, but also on the health condition information of the crew member C acquired previously and stored in the memory unit 31 of the server 30. Then, the judgment unit 113 of the CPU 11 judges the health condition of the crew member C based on the judgment conditions set by the setting unit 112.

In this embodiment, the threshold for judging the health condition of crew member C is set at a smaller interval than when the health condition of crew member C is judged in two stages, namely, able to fly and not able to fly. In contrast, the measured values related to the health condition of crew member C, such as the blood pressure value, vary depending on the individual differences of crew member C. Therefore, when judging the health condition of crew member C based only on the current measured value, for example, the health condition of crew member C, whose blood pressure value is consistently high and stable, may be erroneously judged to be one stage worse, even though his blood pressure value is normal.

Therefore, in this embodiment, the judgment conditions for judging the health condition of the crew member C are set by referring to not only the currently acquired health condition information of the crew member C, but also previously acquired health condition information of the crew member C. This makes it possible to judge the health condition of the crew member C taking into account individual differences, and makes it possible to smoothly carry out operation management when the health condition of the crew member C is judged in detail.

In addition, according to the operation management system 1 of this embodiment, when the judgment unit 113 of the CPU 11 judges that the health condition of the crew member C is such that the crew member C is prohibited from driving, the crew member selection unit 122 of the CPU 11 executes a process to select a substitute crew member. This makes it possible to manage the health of the crew member C and to manage smooth operation.

Furthermore, according to the operation management system 1 of this embodiment, the CPU 41 of the in-vehicle device 40 acquires health condition information of the driver C on duty from the wearable measurement device 50, judges the health condition of the driver C, and transmits the judgment result to the PC 10. This allows the operation manager M to monitor the health condition of the driver C on duty, and in the event of an abnormality, it becomes possible to select a substitute driver during or after the operation. Therefore, it is possible to perform health management of the driver C on duty and smooth operation management.

The present invention has been described above based on the embodiments, but the present invention is not limited to the above embodiments, and modifications may be made without departing from the spirit of the present invention, and publicly known or well-known technologies may be appropriately combined.

For example, in the above embodiment, the CPU 11 as the crew member determination device is provided in the PC 10, but it may be provided in the server 30. Also, the CPU 41 that determines the health condition of the crew member C while on duty is provided in the vehicle-mounted device 40, but it may be provided in the server 30 or the PC 10.

In the above embodiment, the health condition of crew member C is judged in three stages: a first state in which crew member C can work without any driving conditions, a second state in which crew member C can work with driving conditions, and a third state in which crew member C is prohibited from working. However, the health condition may be judged in two stages or four or more stages. In the above embodiment, the judgment condition is set based on the current and previous blood pressure values, or based on the current and previous pulse values. However, the judgment condition may be set based on the average of the current blood pressure value and the previous blood pressure value, or based on the current pulse value and the previous pulse value. In the above embodiment, the judgment condition is set based on the current body temperature value and the previous body temperature value, but the judgment condition may be set based on the average of the current blood pressure value and the previous blood pressure value, or based on the current pulse value and the previous pulse value.

Furthermore, in the above embodiment, the driver C of the truck T is the person to be managed, but the driver C of other vehicles such as a taxi or a forklift may also be the person to be managed.
