[0044]
When these recording processes are completed, the remaining card amount is checked in step S303, and it is determined in step S304 whether the remaining amount is equal to or less than a warning reference value. This 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 shortage of the remaining amount of the card. Here, assuming that the total storage capacity of the memory card 111 corresponds to data for one week, the warning reference value is set to a capacity corresponding to 12 hours (hours). Of course, this value may be appropriately changed with reference to the total storage capacity and storage capacity of the memory card 111. Unless it is determined in this step S304 that the remaining amount is 12Hr or less, the process returns to step S301, and the above steps S301 to S303 are continued (N in step S304). In order to perform recording data transmission, the process proceeds to step S305 and subsequent steps. The steps S303 and S304 correspond to a card remaining amount detecting means and a card remaining amount comparing means, respectively.

That is, as long as the vehicle 2 equipped with the vehicle-mounted device 1 is traveling in a place where the roadside device 4 is not installed, the countdown display is continued.
[0047]
If it is determined in step S307 that the predetermined communication connection is completed between the in-vehicle device 1 and the roadside device 4 (Y in step S307), the recorded data in the memory card 111 is read in step S308. Then, wireless transmission is performed from the vehicle-mounted device 1 to the roadside device 4 by known narrow-area communication. Note that step S306, step S307, and step S308 correspond to a recording data transmission unit in claims. When the data collection / transmission process is performed in this way, the process returns.
[0048]
On the other hand, in step S 308, the roadside device 4 that has received the recording data transmits this data to the computer 801 of the company office 80 via the ETC management center 6. In step J101 and step J102, the computer 801 of the company's office 80 is waiting to receive the recording data from the ETC management center 6 (N in step J102). When the recording data is received, the process proceeds to step J103 (step S103). Y of J102). These steps J101 and J102 correspond to the recording data receiving means in the claims. In step J103, 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 recorded data storage means in the claims. In this way, the company office 80 receives the recording data via the ETC management center 6 and stores the recording data, so that it is possible to analyze the data and take measures immediately. become.
Note that the recorded data stored here may be a part of the data to be collected, so the data recorded in the memory card 111 after the vehicle-mounted device 1 completes the warehousing process is complete, and the analysis process At least until saved. When the recording data receiving process is performed in this way, the process returns.
[0049]
As described above, according to the processing procedure shown in FIG. 6, it becomes possible to backup the shortage of the remaining capacity of the memory card 111 using ETC, and the vehicle operation data including the temperature data can be reliably recorded. It becomes like this. In addition, since part of the recorded data is transmitted to the company office 80 before the memory card 111 is taken back to the company, it is possible to quickly analyze the data and take measures.
[0050]
FIG. 7 is a flowchart showing a part of the processing procedure between the in-vehicle device, the office, and the in-vehicle device-office when data is transmitted from the office to the in-vehicle device in the processing procedure of FIG. That is, the message reception process (steps S311 to S314) of FIG. 7 shows a subroutine on the vehicle-mounted device 1 side when receiving a message in the data collection communication process of step S3 shown in FIG. Message transmission processing (step J111 to step J113) shows a subroutine of the company office 80 when transmitting a message in the data transmission / reception processing of step J1 shown in FIG.

Communication connection is established, and the process proceeds to the office message reception process in step S313 (Y in step S311 and 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, unless the vehicle 2 equipped with the vehicle-mounted device 1 travels in a place where the roadside device 4 is not installed, the process proceeds to the office message reception process in step S313. No (N in step S312). Steps S311 to S313 correspond to message receiving means in the claims.
[0056]
In step S313, an office message is received by narrow area communication. That is, the office message stored in the server of the ETC management center 6 is read and transmitted from the roadside device 4 to the in-vehicle device 1. The transmitted message is received by the narrow area wireless communication unit 110 of the in-vehicle device 1 and then displayed on the display unit 107 in step S314. Simultaneously with this message display, message reception may be issued with a buzzer sound or the like, or a message may be output by voice using a known voice generator not shown here. This step S314 corresponds to the message display means in the claims. When the message reception process is performed in this way, the process returns.
