DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a drive recorder system driving recorder for a vehicle that objectively records the driving status of a vehicle.

[Conventional technology]

Traditionally, airplanes have been required to be equipped with flight recorders, which have become an important means of analyzing flight operations in the event of an accident.

On the other hand, the development of automobile society is remarkable, and electronics in cars are rapidly progressing.

Under these circumstances, car owners are seeking ways to effectively maintain and manage their vehicles, including ``Electronics in Bulldozer Maintenance'', Nippon Kogyo Shuppan, ``Construction Machinery,'' Vol. 17, No. 12, '81. There was an operation recording device shown in No. 12.

In Figure 6, which shows the operation recording system shown in the above-mentioned document in Figure 3, l indicates each building center of the car? , 2 indicates a sensor signal processing device, 3 indicates a recording device, and 1M indicates carrots, oil for the power transmission mechanism, and cooling water.

Sensors connected to the gauges that are generally installed on the dashboard of a car, such as temperature, pressure, charging status of the battery, fuel level, etc. lb is the fuel flow rate sensor.

Ic is a fuel accumulator, ld is a speedometer, 1e is an hour meter, lf is an automatic oil supply mechanism, and 2a is a monitoring instrument connected to sensor 1a.

2b is a fuel consumption calculation processing unit following the sensor lb fuel accumulator 1c; 2c is a unit that performs time integration on the signal from the speedometer ld to calculate the distance traveled; 2d is a processing unit that processes instantaneous speed; 2e indicates a processing section that controls the oil extraction mechanism.

3 indicates a recording device that records electrical signals processed by each processing section.

Next, the operation will be explained. The values of the various sensors 1 and the signals of the various sensors 1 during operation can be processed by the processing device 2 and recorded by the recording device 3 as a function of 1 hour using each sensor 1. .

The recorded results are applied to a data processing device such as a combinatorial computer to determine fuel consumption, vehicle running speed, etc., fuel efficiency, safety, etc.
This can be used as rent for education, etc. of people who have changed jobs.

[Problem that the invention seeks to solve]

The conventional operation recording system was configured as described above, which was sufficient for recording the vehicle's own behavior and operation, but it is not possible to objectively record at what point in the past it passed and what point it passed. I can't do it. Although the distance traveled from the starting point is recorded over time, it is not possible to record which route and route the driver actually took, and must rely on the memories of the driver or witnesses based on interviews. However, there was a problem that it was inaccurate because it was easily forgotten.

This invention was made in order to solve the above-mentioned problems, and the object is to obtain a drive recorder system that can record the driving route of the width of the vehicle traveling on the road, along with objective data. .

[Means for solving problems]

A drive recorder system according to the present invention.

A point signal transmitting device for transmitting a point signal is installed on a road, and a vehicle is equipped with a receiving device to receive this signal and a recording device to process and record the received point signal.

[For production]

In the drive recorder system of the present invention, objective position information on the road is transmitted by a point signal transmitting device installed on the road, and this is transmitted by a point signal receiving device, a processing device, and a recording device installed on the vehicle. Since the information is received and recorded, objective position information is added to the vehicle operation record.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a configuration diagram of a drive recorder system, in which IO indicates a point signal transmitting device installed on the road, 11 indicates a power supply line, 12 indicates an antenna that emits electromagnetic waves, etc., 20
4 is a vehicle that runs on a road; 4 is an antenna that is attached to the vehicle 20 and receives signals from the antenna 12; 5 is a power supply line; 8 is a drive recorder system that includes a point signal receiving device, a processing device, a recording device, etc. shows.

FIG. 2 is a block diagram showing the internal configuration of the drive recorder system 8, where l indicates various sensors installed in the vehicle, 2 indicates a processing unit [1%] that processes sensor signals, and 3 indicates processing by this processing device. 4 is a recording device for recording signals emitted from the antenna 12, an antenna 5 is a feeder line, 6 is a receiving device for radio, etc., and 7 is a signal received and decoded by the receiving device 6. 1 shows a processing device that performs signal processing for recording point signals.

Next, the operation will be explained.

An antenna 1 is transmitted through a power supply line 11 using a point signal transmitting device 10 that converts information indicating a location, such as a point number and a street address code installed on a road, into a wireless signal such as an electromagnetic wave signal.
2 to 9 radiated into the atmosphere.

On the other hand, the vehicle 20 includes a sensor 1 for each building in order to record the driving situation of the vehicle width, a processing device 2 for processing to record the information of the sensor 1, and a processing device 2 for recording the processed signal. A drive recorder system 8 including a recording device 3 is installed.

In order to receive the point signal of the present invention, the antenna 4, the transmitter'tm5, the receiving device 6, and the received M decoded signal are
It is equipped with a processing device 7 that performs signal processing for recording on the recorder 3, receives point signals emitted from the antenna 12 by the antenna 4, receives and combines them in the receiving device 16 via the feeder line 5, and receives the point signals from the antenna 12. The processed results can be recorded on the recording device 3.

When a vehicle 20 equipped with a drive recorder 8 approaches a road equipped with a point signal transmitting device 1O, information indicating a point such as a point number is stored in a recording device 3 provided in the vehicle 20 along with the driving situation of the vehicle 20. You can also record the time.

In addition, in the above embodiment, the device added to the drive recorder of the vehicle was shown, but it is also possible to use only the point signal receiving device and its recording device.

Further, the receiving device may be equipped with a speaker or the like as a monitoring device that provides road guidance information to the driver.Furthermore, although a wireless signal using electromagnetic waves is shown as a point signal transmission, ultrasonic, transparent wireless, or optical It is also possible to send a signal by using the above-mentioned method, and thereby the same effect as in the above embodiment can be achieved.

〔Effect of the invention〕

As described above, according to the present invention, in order to provide objective position information to the drive recorder system, a point signal transmitting device is installed on the road, and a point signal receiving device and a recording device are provided in the width of the vehicle. , it becomes possible to record objective location information in the vehicle operation record, and this makes it possible to improve the accuracy of the operation record and accurately track the operation. Effects can be obtained.
