以下、本発明の実施の形態を図面に基づいて説明する。図１は、一実施の形態に係る速度等計測装置の概略構成図である。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a speed measurement device according to an embodiment.

レール（軌道）Ｒ上を走行する車両（列車）イの車輪のうちの一つの車輪（図１では右側の車輪）Ｗの車軸Ｗ′には、既知の速度発電機Ｇが設けられている。この速度発電機Ｇは、車軸Ｗ′が１回転する毎に所定数、例えば９０パルスの信号を発生して、そのパルス信号を車上装置１に送出するように構成されている。   A known speed generator G is provided on the axle W ′ of one wheel (the right wheel in FIG. 1) of the wheels of the vehicle (train) A traveling on the rail (track) R. The speed generator G is configured to generate a signal of a predetermined number, for example, 90 pulses every time the axle W ′ rotates once, and send the pulse signal to the on-vehicle apparatus 1.

車上装置１は、速度発電機Ｇからのパルス信号を入力するとともに、後述する設定器２との間でデータ授受を行うことのできる入出力部１ａと、ＣＰＵを中心に形成され、車両の走行速度や走行距離の算出等の所定の演算処理を行う制御部１ｂと、車輪径データを記憶しておくことのできる多重化（図１の例では２重化）された不揮発性のメモリ（第１メモリ，第２メモリ）Ｍ1 ，Ｍ2 と、車上装置１（制御部１ｂ）の内容、すなわち、速度や走行距離、あるいは車輪径等の所定の内容を表示したり、その車上装置１を操作するための所定の情報を入力するための表示・操作部１ｃとを有している。
なお、第１メモリＭ1 及び第２メモリＭ2 は、実際は、制御部１ｂを駆動制御するための図示しないメモリの中に設けられるが、ここでは、理解を容易にするために分離して示されている。 The on-board device 1 is formed around an input / output unit 1a that can input a pulse signal from the speed generator G and can exchange data with a setting device 2 described later, and a CPU. A control unit 1b that performs predetermined calculation processing such as calculation of travel speed and travel distance, and a multiplexed non-volatile memory (duplicated in the example of FIG. 1) that can store wheel diameter data ( (First memory, second memory) M1, M2 and the contents of the on-board device 1 (control unit 1b), that is, predetermined contents such as speed, travel distance, wheel diameter, etc. And a display / operation unit 1c for inputting predetermined information for operating.
The first memory M1 and the second memory M2 are actually provided in a memory (not shown) for driving and controlling the control unit 1b, but are shown separately here for easy understanding. Yes.

図中、２は設定器であって、携帯型のパーソナルコンピュータ（パソコン）で構成されていて、ケーブルＬを介して車上装置１に着脱可能である。   In the figure, reference numeral 2 denotes a setting device, which is composed of a portable personal computer (personal computer), and is attachable to and detachable from the on-vehicle device 1 via a cable L.

上記構成による速度等計測装置の制御動作を図２のフローチャートを用いて説明する。今、車両イの速度発電機Ｇが設けてある車輪Ｗが修理されて車輪径に変化が生じたとする。この場合、その車輪Ｗの直径が図示しない計器を用いて精密に、かつ、正確に計測される（ステップ１００。以下、ステップを「Ｓ」とする）。   The control operation of the speed measuring device having the above-described configuration will be described with reference to the flowchart of FIG. Now, it is assumed that the wheel diameter provided with the speed generator G of the vehicle A has been repaired and the wheel diameter has changed. In this case, the diameter of the wheel W is precisely and accurately measured using a meter (not shown) (step 100. Hereinafter, step is referred to as “S”).

設定器２への車輪径Ｄの設定は、計測した車輪を特定するＩＤ及びＣＲＣ等のチェックコードを付加して入力される。そして、車上装置１の設定器２に入力された車輪径データＤは、ケーブルＬを介して車上装置１に送出される（Ｓ１０２）。車輪径データＤを受信した車上装置１では、今回入力した車輪径Ｄとそれまで第１メモリＭ1 及び第２メモリＭ2 にそれぞれ記憶されている車輪径Ｄ′とが比較される（Ｓ２００）。この比較の結果がＤ＜Ｄ′であれば、設定器２から入力したデータＤは正常と判定し（Ｓ２０２肯定）、Ｄ≧Ｄ′であれば、設定器２から入力したデータは異常と判定する（Ｓ２０２否定）。つまり、車輪Ｗの直径が修理により以前よりも小さくなっているにもかかわらず、今回の車輪径Ｄが両メモリＭ1 ，Ｍ2 にそれぞれ記憶されている前の直径Ｄ′よりも大きくなっていることは、計測ミスか設定器２への入力ミスが発生していることを意味しているので、この場合は異常と判定される。   The setting of the wheel diameter D in the setting device 2 is input by adding a check code such as ID and CRC for specifying the measured wheel. Then, the wheel diameter data D input to the setting device 2 of the onboard device 1 is sent to the onboard device 1 via the cable L (S102). In the on-board device 1 which has received the wheel diameter data D, the wheel diameter D inputted this time is compared with the wheel diameters D 'stored in the first memory M1 and the second memory M2 so far (S200). If the result of this comparison is D <D ′, it is determined that the data D input from the setting device 2 is normal (Yes in S202), and if D ≧ D ′, the data input from the setting device 2 is determined to be abnormal. (No at S202). That is, the wheel diameter D of this time is larger than the previous diameter D 'stored in both memories M1 and M2, even though the diameter of the wheel W is smaller than before due to repair. Means that a measurement error or an input error to the setting device 2 has occurred. In this case, it is determined to be abnormal.

異常と判定されたときは、その旨が車上装置１の表示・操作部１ｃに表示されるとともに、設定器２にも表示される（Ｓ２０３）。異常と表示されたときは、車輪径の再計測及び／又は設定器２への再設定が行われる（Ｓ１０４否定）。従って、車輪径の誤設定を防止することができる。   When it is determined that there is an abnormality, the fact is displayed on the display / operation unit 1c of the on-board device 1 and also displayed on the setting device 2 (S203). When it is displayed as abnormal, the wheel diameter is remeasured and / or reset to the setting device 2 (No in S104). Therefore, erroneous setting of the wheel diameter can be prevented.

設定器２から入力された車輪径Ｄが正常と判定されたときは（Ｓ２０２肯定）、その車輪径Ｄが設定器２に返送されて設定器２への車輪径Ｄの入力が正常に行われたことが表示される。これにより設定器２の操作は終了となる（Ｓ１０４肯定、Ｓ１０６肯定）。   When it is determined that the wheel diameter D input from the setting device 2 is normal (Yes in S202), the wheel diameter D is returned to the setting device 2 and the wheel diameter D is normally input to the setting device 2. Is displayed. As a result, the operation of the setting device 2 ends (S104 affirmative, S106 affirmative).

設定器２から受信された車輪径Ｄが正常と判定されたときは、両メモリＭ1 ，Ｍ2 に記憶される（Ｓ２０２肯定、Ｓ２０４、Ｓ２０６）。したがって、車両イは、その両メモリＭ1 ，Ｍ2 に記憶されている車輪径Ｄと速度発電機Ｇからのパルス信号とに基づいて速度又は速度及び走行距離を求めることができる。この速度・走行距離を求めるための制御部１ｂにおける演算処理においては、両メモリＭ1 ，Ｍ2 にそれぞれ記憶されているデータ（車輪径）の照合処理の下に行われるので、正確な速度や走行距離を求めることができる。
なお、速度発電機Ｇの設けられる車輪Ｗが新しい車輪と交換されるときは、設定器２からその新車輪の車輪径データが入力され、かつ、この時は、当然のことながら、両メモリＭ1 ，Ｍ2 にそれまでに記憶されている車輪径のデータとの比較は行われず、それまでに記憶されているデータはクリアされる。そして、新しい車輪径データが記憶される。 When it is determined that the wheel diameter D received from the setting device 2 is normal, it is stored in both memories M1 and M2 (Yes in S202, S204, S206). Therefore, the vehicle A can determine the speed or speed and the travel distance based on the wheel diameter D and the pulse signal from the speed generator G stored in the memories M1 and M2. The calculation process in the control unit 1b for obtaining the speed / travel distance is performed under the collation process of the data (wheel diameter) stored in the memories M1 and M2, respectively. Can be requested.
When the wheel W provided with the speed generator G is replaced with a new wheel, the wheel diameter data of the new wheel is input from the setting device 2, and at this time, of course, both memories M1 , M2 is not compared with the wheel diameter data stored so far, and the data stored so far is cleared. Then, new wheel diameter data is stored.
