【発明の詳細な説明】
〔発明の技術分野〕
本発明は、各車両の個別の情報に基づいて各種の処理を
行なう車両情報処理装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a vehicle information processing device that performs various types of processing based on individual information of each vehicle.
近年の乗用車両の車種の増大および一般家庭への普及は
目ざましく、国内における車両台数も飛躍的に上昇して
いる。このように車両の種類および台数が増加するに伴
い、次のような事柄が問題となる。BACKGROUND ART In recent years, the number of passenger vehicles has increased dramatically and their popularity in households has been remarkable, and the number of vehicles in Japan has also increased dramatically. As the types and number of vehicles increase in this way, the following problems arise.
車類が増加することは、例えば大型、中型、小型等の車
種によって料金の異なる有料道路や駐車場の料金所にお
いて、係員によるこの車種の判別を困難にする。すなわ
ら、何らかの必要に応じて車種を判別する必要がある場
合に、その正確かつ迅速な判別が期し難いのである。The increase in the number of vehicles makes it difficult for staff to distinguish between vehicle types on toll roads and parking lot toll booths where toll rates vary depending on the type of vehicle, such as large, medium, or small. In other words, when it is necessary to identify the vehicle type for some reason, it is difficult to accurately and quickly determine the type of vehicle.
また、車両の整備不良、走行中における突然の故障等を
原因とする交通事故を防止する観点から一部明間毎の車
検あるいは定期点検が法律上で義務づけられれている。In addition, from the perspective of preventing traffic accidents caused by poor vehicle maintenance, sudden breakdowns during driving, etc., vehicle inspections or periodic inspections are required by law at certain intervals.
走行安全の確保という観点からすると、この義務を履行
していないような車両については走行すること自体好ま
しいことでない。特に高速道路では然りである。このた
め、例えば高速道路の入口等のゲートにあっては、前記
義務の履行の確認を車検証等から判断するのが本来であ
るが、車両台数が増加している現状ではこの方法は現実
的でなく却って道路渋滞を発生させ別の意味での走行安
全の低下を招来することになる。すなわち、何らかの必
要に応じて車両個別の情報を確認する場合に、その正確
かつ迅速な確認が期し難いのである。From the perspective of ensuring driving safety, it is not desirable to drive a vehicle that does not fulfill this obligation. This is especially true on expressways. For this reason, for example, at gates such as expressway entrances, it is normal to confirm the fulfillment of the above-mentioned obligations based on vehicle inspection certificates, etc., but this method is not practical as the number of vehicles is increasing. On the contrary, it will cause road congestion and reduce driving safety in another sense. That is, when confirming vehicle-specific information in response to some need, it is difficult to ensure accurate and quick confirmation.
したがって、これらの問題は、総括して考察すると、車
両に関する個別情報を正確かつ迅速に得難いということ
に帰着し、これに対して従来より改善が切望されていた
。Therefore, when these problems are considered as a whole, they result in the difficulty of obtaining individual information regarding a vehicle accurately and quickly, and there has been a long-awaited improvement in this regard.
本発明は、上記に鑑みてなされたもので、その目的とし
ては、車両に関する個別情報を正確かつ迅速に得られる
ようにした車両情報処理装置を提供することにある。The present invention has been made in view of the above, and an object of the present invention is to provide a vehicle information processing device that can accurately and quickly obtain individual information regarding a vehicle.
上記目的を達成するため、本発明は、車両に設けられ、
外部からの起動電波によって誘起された電力で動作して
当該車両に関して予め記憶している各種の情報を電波送

トランスポンダに対して前記起動電波を送信してトラン
スポンダから送信される情報を入力し、この情報を用い
て前記車両に関する所定の処理を行なう処理手段とを有
することを要旨とする。In order to achieve the above object, the present invention is provided in a vehicle,
a transponder that operates with electric power induced by an external activation radio wave and transmits various information stored in advance regarding the vehicle by radio waves, and when the vehicle approaches,
The gist of the present invention is to include processing means for transmitting the activation radio wave to the transponder, inputting information transmitted from the transponder, and using this information to perform predetermined processing regarding the vehicle.

ある。FIG. 3 is a diagram showing the configuration blocks of the terminal device 1. As shown in FIG. The terminal b11 constitutes a processing means, and mainly reads information from the transponder 9 of the vehicle 11 and performs processing such as displaying fares, issuing receipts, and controlling the opening and closing of a gate (not shown). The configuration is, for example, mainly composed of a microcomputer, with a CPU 29 for the bus 28, a memory 31 storing predetermined processing programs, a display 33 for displaying various calculation results to the staff, and a hard copy (hard copy) for displaying various calculation results. A printer 35 for issuing receipts (including issuance of receipts), a keyboard 37 for inputting information by staff are connected, and a charge display drive unit 40 controls the display of the charge display 5, and its output is connected to the antenna 7 and the transmitter/receiver 39. The code decoder 41 is connected to the code decoder 41 which is connected to the code decoder 41 . The three transmitters and receivers are antenna 7
The configuration has a transmitting circuit and a receiving circuit that control the emission or reception of radio waves in the transmitter.When a startup command signal is received from the CPU 29 via the code decoder 41, the transmitting circuit is activated to radiate the startup radio wave from the antenna 7 to the transponder 9. When the information regarding the vehicle 11 is transmitted from the transponder 9, the receiving circuit is activated to receive the information, demodulate it, and supply it to the code decoder 41. The code decoder 41 decodes the encoded vehicle 11 information stored in the memory 21 of the transponder 9 supplied from the transmitter/receiver 39 and supplies it to the CPU 29 .
次に本実施例の作用を説明する。Next, the operation of this embodiment will be explained.
車両１１が高速道路に入るべく料金所ブース３に着くと
、端末機１のＣＰＵ２９は発受信器３９を駆動させアン
テナ７から起動電波を１１ｉ射させる。When the vehicle 11 arrives at the tollgate booth 3 to enter the expressway, the CPU 29 of the terminal device 1 drives the transmitter/receiver 39 and causes the antenna 7 to emit a startup radio wave 11i.
この起動電波を受けたトランスポンダ９は、作動開始し
メモリ２１に記憶されている情報をコイル１３を介して
前記アンチ゛す７に放射する。The transponder 9 that receives this activation radio wave starts operating and radiates the information stored in the memory 21 to the antenna 7 via the coil 13.
この放射された情報は、アンテナ７で受波され発受信器
３つで復調されてコード解読器４１に供給され、コード
解読器４１はこの情報を解読しその結果をバス２８を介
してＣＰＩＪ２９に出力する。This radiated information is received by the antenna 7, demodulated by the three transmitter/receivers, and supplied to the code decoder 41. The code decoder 41 decodes this information and sends the result to the CPIJ 29 via the bus 28. Output.
ＣＰＵ２９は、この解読された車両１１の情報に基づき
、例えば次のような処理を行なう。The CPU 29 performs, for example, the following processing based on the decoded information about the vehicle 11.
（１）車両１１の情報のうち、車両１１の車種、サイズ
、重、に等の情報を用いて、例えば大型、中型、小型の
判別を行ない、この判別に応じて予め大型。(1) Among the information on the vehicle 11, information such as the vehicle type, size, weight, etc. of the vehicle 11 is used to determine whether the vehicle 11 is large, medium, or small, and the size is determined in advance according to this determination.
中型、小型に定められている走行料金をメモリ３１から
読み出し、料金表示駆動部４０を介して料金表示器５に
表示される。これにより、車種の判別が自動的に正確か
つ迅速に行なわれることになり、係員の負担軽減に寄与
することができる。The travel fees determined for medium and small vehicles are read from the memory 31 and displayed on the fee display 5 via the fee display drive section 40. Thereby, the vehicle type can be automatically and accurately and quickly determined, which can contribute to reducing the burden on the staff.
（２） 車両１１の情報のうち、車両１１の車検整備
状況、定期検査の受診状況等の情報を用いて、車両１１

性の向上に寄与することができる。(2) Among the information on the vehicle 11, the vehicle 11 is
If it is determined that there is a problem with high-speed driving, a gate control unit (not shown) is controlled to prevent the entrance gate to the expressway from opening. This can contribute to improving driving safety on expressways.
（３）車両１１の情報のうち、車両１１の製造番号等の
情報を用いて、車両１１が盗難届あるいは手配届の出て
いる車両である場合には、前記入口ゲートの開動作を行
なわせないと同時に図示しない警察への直流伝送路を介
して警報信号を出力する。(3) Using information such as the serial number of the vehicle 11 among the information on the vehicle 11, if the vehicle 11 is a vehicle that has been reported stolen or wanted, the entrance gate is opened. At the same time, an alarm signal is outputted via a DC transmission line to the police (not shown).
これにより、盗難車あるいは手配車の発見への迅速な対
処を行なうことが可能となる。This makes it possible to quickly respond to the discovery of a stolen vehicle or a wanted vehicle.
なお、ＣＰＵ２９における処理としては、この３種類に
限定されないことは勿論である。また、本実施例では、
車両情報処理装置を有料道路の料金所に設置した場合に
ついて説明したが、他に例えば駐車場の入口等に用いて
もよいことは勿論で、この設置場所に応じてＣＰＵ２９

る。Note that it goes without saying that the processing performed by the CPU 29 is not limited to these three types. Furthermore, in this example,
Although the case where the vehicle information processing device is installed at a toll gate of a toll road has been described, it is of course possible to use it at other places such as the entrance of a parking lot, and depending on the installation location, the CPU 29
Of course, the processing program has also been changed accordingly.
