As shown in the flowchart of FIG. 5, first, in step S1 of the vehicle-mounted device processing, it is determined whether or not the memory card 111 is inserted into the slot of the reader / writer unit 109 (FIG. 3). Here, the card 111
When it is determined that is inserted, the process shifts to step S2 to perform the retrieval process (Y in step S1), repeats step S1 unless it is inserted, and waits for card insertion (N in step S1). The determination of the insertion of the card 111 may be performed by a mechanical method based on the fact that the card 111 is mounted at a predetermined position, or may be electrically determined by the control unit 1.
It may be based on the fact that the card 111 can be accessed from 01.

In step S2, a predetermined delivery process is performed. The retrieval process is a preparation and initialization process for accurately collecting temperature and operation data, such as a remaining amount check and a date check of the memory card 111, for example.

In the subsequent step S3, a data collection communication process is performed. In this process, vehicle operation data including temperature data is collected, and the memory card 11
1 is recorded. When the remaining storage capacity of the memory card 111 is equal to or smaller than the warning reference value, when the vehicle-mounted device 1 passes through the communication area of the roadside device 4 (either 41, 42 or 43), the roadside device 4 And short-range communication is performed.

FIG. 6 is a flowchart showing a part of the processing procedure between the vehicle unit, the office, and the vehicle unit-office when data is transmitted from the vehicle unit to the office in the processing procedure of FIG. is there. That is, the data collection and transmission process (steps S301 to S308) in FIG. 6 shows a subroutine on the vehicle-mounted device 1 side when transmitting data in the data collection and communication process in step S3 shown in FIG.
The recording data reception processing (steps J101 to J103) in FIG. 6 shows a subroutine of the company office 80 when receiving data from the vehicle-mounted device 1 in the data transmission / reception processing in step J1 shown in FIG.

As shown in the flowchart of FIG. 6, first, in step S301 of the in-vehicle device processing, the temperature data detected by the temperature sensor unit 104 is collected and recorded on the memory card 111 via the reader / writer unit 109. Is done. From the temperature data, a maximum temperature, an optimum temperature, an average temperature, and the like are generated. Step S302
, Vehicle operation data other than the temperature data detected by the various sensor units 105 is collected, and these are also recorded on the memory card 111 via the reader / writer unit 109. From this vehicle operation data, the departure time, arrival time,
Operation management data such as running time, distance, work, and break time, and safety management data such as maximum speed and average speed are generated. Steps S301 and S302 correspond to a data recording unit in the claims.

When these recording processes are completed,
In step S303, the remaining card amount is checked, and in step S304, it is determined whether the remaining amount is equal to or less than the warning reference value. The warning reference value is a reference value that is set in advance in consideration of the total storage capacity of the card, the consumption rate of the storage capacity per unit time, and the like in order to warn of the insufficient remaining amount of the card. Here, the memory card 111
Is assumed to correspond to one week of data, the warning reference value is set to a capacity corresponding to 12 hours (hours). Of course, this value is
1 may be changed as appropriate with reference to the total storage capacity, storage capacity, and the like. Unless it is determined in step S304 that the remaining amount is equal to or less than 12Hr, the process returns to step S301 to continue steps S301 to S303 (N in step S304).
The process proceeds to step S305 and thereafter to perform a card remaining amount warning and recording data transmission. Note that the above step S303
And step S304 correspond to a card remaining amount detecting means and a card remaining amount comparing means, respectively.

In step S305, the display unit 10
7 is displayed to warn the user that the remaining amount of the card is insufficient. The remaining amount warning is displayed by counting down a number corresponding to the remaining amount, for example, so that the remaining amount is easily recognized. Although not shown, a sound warning may be given by a buzzer sound or the like when the remaining amount is insufficient. As described above, when the remaining amount of the card is equal to or less than the warning reference value, a warning is issued that the remaining amount is insufficient.
Appropriate countermeasures such as transmission to 0 can be taken. In addition, since the remaining amount is displayed as being counted down, it is easy to recognize the remaining amount, and more effective countermeasures can be taken. Step S305 corresponds to a remaining amount insufficient warning unit in the claims.

Next, in step S306, the short-range wireless communication unit 110 and the roadside device 4 are connected for communication. For this communication connection, a method similar to the known ETC performed at the toll gate is applied. That is, when the vehicle 2 equipped with the vehicle-mounted device 1 approaches the vicinity of the roadside device 4 and the vehicle-mounted device 1 passes through the communication area of the roadside device 4, the short-range wireless communication unit 110 and the roadside device 4 perform the predetermined procedure. Communication is established. However, unless it is determined in step S307 that the connection has been completed, the countdown display in step S305 is continued (N in step S307). That is, the vehicle 2 on which the on-vehicle device 1 is mounted is
As long as the vehicle is traveling in a place where is not installed, the countdown display is continued.

If it is determined in step S307 that the predetermined communication connection between the on-vehicle device 1 and the roadside device 4 has been completed (Y in step S307), the recording data in the memory card 111 is read in step S308. It is transmitted and wirelessly transmitted from the vehicle-mounted device 1 to the roadside device 4 by known narrow-area communication. Steps S306, S307, and S308 correspond to a recording data transmitting unit in the claims. When the data collection and transmission processing is performed in this manner, the process returns.

On the other hand, in step S 308, the roadside device 4 having received the recorded data transmits the data to the computer 80 of the company office 80 via the ETC management center 6.
Send to 1. Computer 801 in company office 80
In steps J101 and J102,
The recording data from the ETC management center 6 is waiting to be received (N in step J102). When the recording data is received, the process proceeds to step J103 (Y in step J102). These steps J101 and J102 correspond to the recording data receiving means in the claims. Step J1
At 03, the received recording data is stored in a storage unit such as a hard disk built in the computer 801. This step J103 corresponds to a recording data storage unit in the claims. As described above, the company office 80
Since the recording data is received via the C management center 6 and the recording data is stored, it is also possible to analyze the data and take measures promptly. Note that the recorded data stored here may be a part of the data to be collected. Therefore, the data recorded on the memory card 111 after the in-vehicle device 1 completes the warehousing process is completed, and the analysis process is performed. At least until saved. When the recording data receiving process is performed in this manner, the process returns.

As described above, according to the processing procedure shown in FIG. 6, it is possible to back up the shortage of the remaining amount of the memory card 111 by using the ETC, and to surely execute the vehicle operation data including the temperature data. Can be recorded.
Further, before the memory card 111 is brought back to the company, a part of the recording data is transmitted to the company office 80, so that data analysis and measures can be taken immediately.

FIG. 7 is a flowchart showing a part of the processing procedure between the vehicle-mounted device, the office, and the vehicle-mounted device-office when data is transmitted from the office to the vehicle-mounted device in the processing procedure of FIG. is there. That is, the message receiving process (steps S311 to S314) of FIG. 7 shows a subroutine of the vehicle-mounted device 1 when receiving a message in the data collection communication process of step S3 shown in FIG. The message transmission process (steps J111 to J113) is a subroutine of the company office 80 when transmitting a message in the data transmission / reception process of step J1 shown in FIG.

As shown in the flowchart of FIG. 7, first, in step J111 of the office process, it is awaited that a predetermined time has elapsed (N in step J111). The certain time indicates an interval for updating the message, and is, for example, one hour. And
In this step J111, for example, when it is determined that one hour has elapsed from the previous message update time, the process proceeds to step J112 to update the message (Y in step J111).

Next, in step J112, the office message to be transmitted to the vehicle-mounted device 1 is updated. Examples of the office message include collection and delivery information, road traffic information, in-house emergency information, and private information.
Of course, other information may be used. This step J112 corresponds to a message updating means in the claims.

Then, in step J113, the above message is transmitted to the ETC management center 6 online using packet communication or the like. When the message transmission process is performed in this manner, the process returns. In addition, ETC
The message received by the management center 6 is
Until the transmission to the in-vehicle device 1 is completed, the data is stored in the server of the management center 6 or the like. This step J113
Corresponds to the message transmission means in the claims.

As described above, the company office 80 periodically updates the message to be transmitted and sends this message to the ET.
Since the driver is transmitted to the C management center 6, the driver can recognize the updated message every time he passes near the roadside device 4. As a result, it is possible to perform operations without leakage, and the quality of transported luggage is improved.

On the other hand, in steps S311 and S312 of the message receiving process on the on-vehicle device 1, the short-range wireless communication unit 110 and the roadside device 4 are connected for communication. That is, when the vehicle 2 equipped with the vehicle-mounted device 1 approaches the vicinity of the roadside device 4 and the vehicle-mounted device 1 passes through the communication area of the roadside device 4,
The short-range wireless communication unit 110 and the roadside device 4 are communicatively connected according to a predetermined procedure, and the process shifts to an office message receiving process in step S313 (step S311 and Y in step S312). For this communication connection, a method similar to the known ETC performed at the toll gate is applied. However, unless it is determined in step S312 that the connection has been completed, that is, the vehicle 2 equipped with the on-vehicle device 1
Unless driving in a place where the roadside machine 4 is not installed,
The process does not shift to the office message receiving process in step S313 (N in step S312). Step S311 above
Step S313 corresponds to a message receiving unit in the claims.

In step S313, the office message is received by the short-range communication. That is, ETC
The office message stored in the server of the management center 6 is read and transmitted from the roadside device 4 to the vehicle-mounted device 1. After the transmitted message is received by the short-range wireless communication unit 110 of the vehicle-mounted device 1, the process proceeds to step S31.
