2. Description of the Related Art Conventionally, a technique for recording vehicle mileage information and / or vehicle speed information in association with time information has been known, and is widely used as a device for recording the operating state of trucks and taxis. Various devices are commercially available, such as a simple analog type device that records speed information on a recording disk that rotates together with the hands of a clock, and a device that records digital information on a recording medium.

On the other hand, the applicant of the present application has filed a patent application for an invention of a device for calculating a rational delivery order of delivery trucks in order to deliver packages to a plurality of destinations (Japanese Patent Application No. Hei 3).
-112611 and Japanese Patent Application No. 3-296060, both of which have not been published at the time of filing the present application). This is because if you use tens or hundreds of trucks and arrange delivery of a very large number of packages prepared according to each order to hundreds of destinations, It is a device for rationally determining the patrol order of the cargo and its delivery destination.

[0005]

The above-mentioned device for deciding the circulation order of the delivery destination has started its operation. However, in order to operate this smoothly, the contents calculated and arranged and the actual operation are carried out. Differences in results, changes in traffic conditions, the addition of new delivery destinations, the time required from a delivery destination in the vicinity to the new delivery destination, and other necessary information must be correctly entered and updated constantly. For this purpose, it is necessary to obtain an accurate operation record with a reasonable number of man-hours without directly manipulating it.

On the other hand, a position measuring device which receives a radio wave emitted synchronously from a satellite and measures the position has become relatively inexpensive and easy to use. The present invention focuses on improving the accuracy of operation records by using this device.

This device or system is a GPS (Globa
l Positioning System), in which synchronized radio wave signals are broadcast from artificial satellites arranged every 60 degrees of the earth's longitude. It is possible to simultaneously receive signals from three or more satellites by a device that moves on the surface of the earth, detect the relative arrival time difference of the signals, and calculate the current position. For this purpose, the receiving device is sufficient, and the device can be easily used by purchasing a commercially available device without requiring a radio license. In general, the position information obtained with this device is displayed in latitude and longitude, and its accuracy is several tens of meters even with the use of a receiving device that can be easily obtained. is there. As a device for vehicles using this system, the output position information of this system is used together with the map information installed in the vehicle, and a map centering on the current position of the vehicle is displayed on the image display device in the driver's seat. Things to do are being developed.

If the GPS is installed in a vehicle and operation records can be easily obtained, the range of application will be expanded.

The present invention has been made against such a background, and an object of the present invention is to obtain an operation record of a vehicle with a small number of man-hours and very accurately without manpower. It is an object of the present invention to provide a device capable of recording accurate position information together with other information about a vehicle (for example, information about a traveling distance). An object of the present invention is to obtain an operation record of a vehicle in such a form that it can be directly used by being put into another computer.

Next, the operation of the embodiment of the present invention will be described with reference to FIG. FIG. 2 is a flow chart showing the operation of the apparatus of the present invention. When the engine of the vehicle 11 equipped with the device of the present invention is started, the operation recording device, which is the device of the present invention, is powered on in synchronization with the engine (S).
1). When the power is turned on, each unit starts operating and the operation record is recorded in the recording circuit 3. In particular, the GPS receiver 2
Receives a radio wave from a GPS satellite and outputs position information to the recording circuit 3. At this time, if the reception state from the artificial satellite deteriorates (S2), the time information from the clock circuit 1 and the travel distance information from the distance detection circuit 5 are based on the position information when the GPS is operating well. The recording circuit 3 calculates the current position on the basis of the azimuth information from the azimuth detection circuit 6 and records it (S4). As a result, it is possible to eliminate the loss of position information when the radio wave from the artificial satellite is not received while traveling in a tunnel or the like. When the vehicle stops the engine (S5), the off sequence is executed. That is, the operation recording device, which is the device of the present invention, copies various information recorded in the memory of the recording circuit 3 to the floppy disk or IC card. In step S6, the subsequent recording position is searched (S7). If not, the recorded content is copied as it is (S8) and the power of the apparatus is turned off.

In the apparatus of the embodiment of the present invention, the recording of the recording circuit 3 is copied to the recording medium in synchronism with the stop of the engine. However, the memory capacity of the recording circuit 3 is reduced and immediately before the data becomes full. It is also possible to adopt a configuration in which copying is performed on the recording medium each time. Further, the two configurations can be combined.

Next, an application example of the embodiment of the present invention will be described with reference to FIG. FIG. 3 is a diagram showing an application example of the apparatus according to the present invention. As described in the conventional example, there is a device for calculating a rational delivery order of delivery trucks in order to deliver packages to a plurality of destinations. This is because if you use tens or hundreds of trucks and arrange delivery of a very large number of packages prepared according to each order to hundreds of destinations, It is a device for rationally determining the patrol order of the cargo and its delivery destination.

Accurate position information and time information are required to create such an operation plan. If such information is not available, the optimal vehicle allocation plan will be inaccurate. By using the device according to the embodiment of the present invention, it is possible to accurately and easily compare the created plan with the actual delivery status, and to rationally create the next delivery procedure.
