Description

  The present invention relates to a mail transmission / reception system that transmits mail from a service management side to a vehicle side via a mail transmission mechanism.

As such a system, for example, a mail transmission / reception system in which a communication function is added to a digital tachograph is known.
Here, when mail is distributed from the operation management side to the driver, there is a case where the driver or the vehicle side terminal that is the destination of the mail cannot receive the mail. For example, if the driver is driving the vehicle during the night time, but the operation manager sends an email during the daytime, the vehicle is not operating when the email is sent. Since the vehicle side mail receiving terminal is in an inoperative state, it is not possible to receive mail. Here, from the viewpoint of preventing battery consumption, mail is not automatically received on the vehicle side in a time zone during which the vehicle is not operating (so-called “after work” time zone). Therefore, in the time zone when the vehicle is not operating, the mail from the operation management side cannot be received on the vehicle side.

As described above, when the driver or the vehicle side terminal cannot receive the mail, the mail transmission / reception system has a problem that the mail transmitted from the operation management side is deleted without being received by the driver or the terminal side. doing.
In addition, there is no problem when the vehicle or the mail receiving terminal on the vehicle side is used for each driver, but when a plurality of drivers use one vehicle, it is addressed to a specific driver. There is also a problem that it is not possible to send e-mail.

Various other techniques have been proposed (Patent Documents 1 to 4), but none of them discloses a means for simultaneously solving the above-described problems.

Can be configured.
Although not shown in FIGS. 2 and 3, the display screen is provided with a touch switch for switching the screen and a touch switch for returning the display screen to the previous screen.

Next, control related to mail reception in the terminal 3 will be described with reference to FIG.
In FIG. 4, the terminal 3 is turned on in step S1, and a display screen is started up (step S2). Then, the driver identification number (driver ID) is input to confirm the driver identification number displayed in the area 341 and press the start switch 342 to inform the mail center 2 that the driver identification number and the vehicle have started. Transmit (step S3).
Here, when the driver ID is input and transmitted to the mail center 2, the ID of the terminal 3 is also automatically transmitted from the transmission device 32 to the mail center 2.

In the illustrated embodiment, when a plurality of drivers drive the same vehicle, a mail addressed to a specific driver is configured to be received only by the specific driver, and a driver identification number (driver ID) is set. Configured to send.
On the other hand, when only one driver drives one vehicle, it is not necessary to transmit the driver identification number. Only the identification number (terminal ID) of the terminal 3 of the vehicle needs to be transmitted to the mail center 2.
Here, in the illustrated embodiment, the identification number of the terminal 3 is automatically transmitted from the transmission device 32 to the mail center 2 when the power of the terminal 3 is turned on (step S3) without being input by the driver. Is done. Of course, it is possible to configure the driver to input the ID of the terminal 3 every time the vehicle starts.

When the driver identification number (or driver identification number and terminal identification number) and information indicating that the vehicle is in the start-up state are sent to the mail center 2, the mail center 2 sends the mail sent to the driver. The presence or absence is determined (step S4).
Here, the mail center 2 determines whether or not there is a mail deposited for the driver based on the driver identification number added to the mail.
If there is no need for driver identification, the mail center 2 determines the presence or absence of mail deposited to the terminal based on the terminal identification number added to the mail.

If there is a mail addressed to a specific driver (or mail addressed to a specific terminal) (YES in step S4), the mail stored in the mail center 2 is transmitted and received by the terminal 3 (step S4). S5). Then, the process proceeds to step S6.
In steps S4 and S5, if the driver is working in the daytime and the working hours coincide with the management office 1, the mail from the management office 1 is sent in real time via the mail center 2. Received by terminal 3.
On the other hand, if the driver is working at night and the working time zone does not match that of the management office 1, the mail from the management office 1 is temporarily stored in the mail center 2, and then the driver's work is performed. Received at terminal 3 at start.
If the terminal 3 receives a mail from the mail center 2 in step S5, a notification to the effect that it has been received is transmitted to the mail center 2.
In step S6, the driver is notified that the mail has been received by, for example, blinking a sound generator (not shown) or a high-intensity LED lamp (not shown).
If there is no mail addressed to a specific driver (or mail addressed to a specific terminal) (NO in step S4), the process proceeds to step S11.

In the illustrated embodiment, the received mail is configured such that the beginning part thereof (the part that can be displayed on the mail content display unit 348) is automatically displayed on the mail content display unit 348.
Here, since it is dangerous to check the mail while driving, which increases the burden on the driver, in the illustrated embodiment, the automatic display of the received mail is performed when the vehicle stops. Done.
Therefore, in step S7, it is determined whether or not the automobile is stopped. For example, if the vehicle speed measured by a speed sensor (not shown) is zero for a predetermined time or longer, the vehicle is determined to be “stopped”.

If it is determined that the vehicle is “stopped” (YES in step S7), the beginning part of the received mail (the part that can be displayed on the mail content display unit 348) is displayed on the mail content display unit 348. Then, the process proceeds to step S9.
On the other hand, if it is not determined that the vehicle is stopped, the process returns to step S7 (step S7 is NO loop).

In step S9, an operation for opening the mail is performed. When the opening operation is performed, a notification that the mail has been opened is transmitted to the mail center 2 (step S10).
Then, the process returns to step S4.
The operations in steps S4 to S10 are continued until there is no mail addressed to a specific driver (or mail addressed to a specific terminal) in the mail center 2 (until NO in step S4).
Although not shown, an automatic mail display (step S8) may be performed after performing an opening operation (step S9) and sending a notification to the mail center 2 that the mail has been opened (step S10).

If there is no mail addressed to the specific driver (or mail addressed to the specific terminal) in the mail center 2 (NO in step S4) and the process proceeds to step S11, the driver continues the work by the vehicle (without ending work). Or whether the day's work ends.
If the work is not over (step S11 is NO), the process returns to step S4.
If the end of the work (YES in step S11), the process proceeds to step S12, and the driver presses the end of work switch 343 (see FIG. 2) to send a notice of end of work to the mail center 2 via the wireless communication network 50 and receive the mail at the terminal 3. The control regarding is terminated.

Next, transmission / reception control in the mail center 2 will be described with reference to FIG.
In FIG. 5, in step S <b> 21, the receiving means 21 of the mail center 2 receives mail from the management office 1.
In step S22, the receiving means 21 of the mail center 2 receives the start / end notification from the terminal 3 on the vehicle side. Here, the identification information of the terminal and the identification number of the driver (or identification information of the terminal 3) are added to the start / end notification from the vehicle side terminal 3.
Here, step S21 and step S22 may be executed in reverse order or may be executed simultaneously.

In step S23, the mail received from the management office 1 by the receivable state determination device 23 of the mail center 2, and the identification number of the vehicle side terminal 3 added thereto is the working number received in step S22. It is determined whether or not it matches the identification number of the terminal 3 of the vehicle.
In other words, in step S23, whether or not an email with the identification number of the terminal 3 of the vehicle being worked on and the identification number of the same terminal 3 is received in step S21 (or stored in the database 22). Or not).

In step S23, when the identification number (identification number of terminal 3) that matches the identification number of terminal 3 added to the mail from management office 1 does not exist in the identification number of terminal 3 received in step S22 ( Step S23 is NO), the process proceeds to step S26, the mail received in step S21 is stored in the database 22, and the fact that the mail has not been transmitted is transmitted to the operation management side.
When the identification number (the identification number of the terminal 3) that matches the identification number of the terminal 3 added to the mail from the management office 1 is present in the identification number of the terminal 3 received in step S22 (step S23). Is YES), the process proceeds to step S24.

In step S24, it is determined whether a driver ID is added to the mail.
As described above, in the illustrated embodiment, a plurality of drivers are driving the same vehicle, and in order to allow only a specific driver to receive a mail addressed to a specific driver, the driver identification number is used. There are two types: the case where the driver is added and the case where only one driver drives one vehicle and no driver identification number is added. Step S24 is a process provided to distinguish between the case where the driver identification number is added and the case where the driver identification number is not added.
If the driver identification number is added (YES in step S24), the process proceeds to step S25.
If the driver identification number is not added (step S24 is NO), the process proceeds to step S28.

In step S25, is the mail received from the management office 1 by the receivable state determination device 23 of the mail center 2 and whether the driver identification number added thereto matches the driver identification number received in step S22. Judge whether or not.
In other words, in step S25, whether or not an email with the same driver identification number as the working driver identification number is received in step S21 (or whether it is stored in the database 22). Judging.

In step S25, if the driver identification number that matches the driver identification number added to the mail from the management office 1 does not exist in the driver identification number received in step S22 (NO in step S25), the process proceeds to step S26. The mail received in step S21 is stored in the database 22, and the management office 1 is notified that the mail has not been transmitted.
If the driver identification number that matches the driver identification number added to the mail from the management office 1 exists in the driver identification number received in step S22 (YES in step S25), the process proceeds to step S28.

In step S28, a mail is transmitted to the terminal 3 on the vehicle side, and the fact that the mail has been transmitted is transmitted to the management office 1 (step S29).
Then, the process returns to step S21 ("Return" in FIG. 5), and step S21 and subsequent steps are repeated.
In step S23, the identification number of the terminal 3 is not transmitted to the mail center 2 in a state where the vehicle is not operating (for example, after the vehicle is closed until the identification number of the terminal 3 is transmitted to the mail center 2). Therefore, it is determined as “NO” in step S23, and the mail added with the identification number of the terminal 3 is stored in the database 22 without being transmitted to the terminal 3 (step S26). Then, the process returns to step S21 ("Return" in FIG. 5), and step S21 and subsequent steps are repeated.

When the vehicle to which the mail is to be transmitted is operating, the identification number of the terminal 3 is received by the mail center 2 (step S22). Therefore, step S23 is determined as “YES” and the driver ID is not checked. In the case (step S24 is NO), the mail is transmitted to the terminal 3 (step S28).
Further, after the loop of “NO” is repeated in step S23, if the vehicle to which the mail is to be transmitted starts working, the identification number of the terminal 3 is received by the mail center 2, and the terminal identification number added to the mail Since they match (YES in step S23), if the driver ID is not checked (NO in step S24), a mail is transmitted to the terminal 3 (step S28).

Even if “YES” is determined in step S23, only the driver can receive mail addressed to the specific driver. If the specific driver is not working, the driver is determined in step S22. Since the ID is not transmitted to the mail center 2, it is determined as “NO” in step S25, and the mail with the identification number of the driver is not transmitted to the terminal 3 but stored in the database 22 (step S26). ).
Then, the process returns to step S21 ("Return" in FIG. 5), and step S21 and subsequent steps are repeated.

If the driver who should receive the mail starts working, the identification number of the driver is received at the mail center 2 (step S22). Therefore, step S25 is determined to be “YES”, and the vehicle on which the driver is on is determined. A mail is transmitted to the terminal 3 (step S28).
In addition, after the loop of “NO” is repeated in step S25, if the driver to send the mail starts working, the identification number of the driver is received by the mail center 2, and the driver identification number added to the mail Since they match (YES in step S25), an e-mail is transmitted to the terminal 3 of the vehicle on which the driver is on (step S28).

Next, mail transmission in the management office 1 will be described with reference to the flowchart of FIG.
In step S41 of FIG. 6, on the management office 1 side, an e-mail with the identification number of the specific terminal 3 added or an e-mail with the identification number of the specific terminal 3 and the identification number of the specific driver created. (Step S41).
When there is only one driver driving one vehicle and it is not necessary to input the driver identification number, only the identification number of the specific terminal 3 is added to the mail. On the other hand, if a plurality of drivers are driving the same vehicle and mails addressed to a specific driver can be received only by the specific driver, the identification of the driver is added to the identification number of the terminal 3 A number is added to the mail.

In step S42, the mail created (or input) in step S41 is transmitted to the mail center 2 by the mail transmitting means 13.
And it returns to step S41, and whenever it is necessary to transmit a required mail to the vehicle side terminal 3 or a specific driver, a mail is created (input) and transmitted.

As described with respect to the mail center 2, in the illustrated embodiment, when the vehicle is not in operation, the mail with the identification number of the terminal 3 is stored in the database 22 without being transmitted to the terminal 3 ( Step S26 in FIG.
When the vehicle to which the mail is to be transmitted is operating, the mail is transmitted from the mail center 2 to the terminal 3 having the identification number of the terminal 3 added to the mail (step in FIG. 5). S28).

When the mail addressed to a specific driver can only be received by the driver, if the specific driver is not working, an email with the driver identification number is sent to the terminal 3 Instead, it is stored in the database 22 (step S26 in FIG. 5).
If the driver who should receive the step is working, a mail with the identification number of the driver is transmitted to the terminal 3 of the vehicle on which the driver is on (step S28).

According to the mail transmission / reception system according to the illustrated embodiment, the mail center 2 stores the mail addressed to the terminal 3 without transmitting the mail unless the terminal 3 on the vehicle 10 side is capable of receiving the mail, and manages the administrative work. If the terminal 3 is in a state where mail can be received, the mail can be transmitted to the terminal 3.
Therefore, the operation time of the vehicle 10 and the operation time of the management office 1 are different, the vehicle is not working at the moment when the mail from the management office 1 is transmitted, and the terminal 3 cannot receive the mail. Even so, the mail is stored in the mail center 2 and is transmitted to the terminal 3 when the destination vehicle of the mail is in a working state and can be received.
Therefore, since the mail is reliably transmitted to the driver of the vehicle 10, the efficiency of communication office work is improved, and loss due to a transmission error can be prevented in advance.

Here, when a plurality of drivers are driving according to an operation shift for a specific vehicle, it may be desired to send an e-mail to a specific individual among the plurality of drivers.
According to the illustrated embodiment, the identification number of the driver that should receive the mail is added to the mail transmitted from the management office 1, and the information indicating that the mail transmitted from the terminal 3 is ready is also received. A driver identification number is added, and the mail is sent to the terminal 3 only when the driver identification number added to the mail matches the driver identification number added to the information indicating that the mail can be received. I can do it.
Therefore, the mail addressed to the driver is transmitted to the terminal 3 only when the driver having the identification number is driving the vehicle. As a result, even when a plurality of drivers use the same terminal 3, the mail can be transmitted only to a specific driver.

 The illustrated embodiment is merely an example, and is not intended to limit the technical scope of the present invention.
