Abstract
Description
Anordnung zum Erfassen des Standortes eines FahrzeugsArrangement for detecting the location of a vehicle
Die Erfindung betrifft eine Anordnung nach dem Oberbegriff des Anspruchs 1. Eine solche Anordnung ist z. B.- aus der DE-OS 27 54 024 bekannt.The invention relates to an arrangement according to the preamble of the claim 1. Such an arrangement is z. B.- from DE-OS 27 54 024 known.
Zur Bestimmung des Standortes eines Fahrzeugs, das eine vorbestimmte Route fährt, wird außer durch Ortscodeeinrichtungen,- die dem Fahrzeug punktweise den momentanen Standort übermitteln, die zurückgelegte Strecke mittels einer Wegmeßeinrichtung-erfaßt. Bei der Wegmeßeinrichtung handelt es sich meist um einen Wegimpulsgeber, der ca.To determine the location of a vehicle that has a predetermined Route is driven, except by location code devices, - which the vehicle point by point transmit the current location, the distance covered by means of a distance measuring device-recorded. The position measuring device is usually a position pulse generator that measures approx.
alle 1 m Fahrstrecke einen Impuls abgibt. In rechnergesteuerten Botriebsleitsystemen werdeS-die Fahrzeuge des Systems zyklisch von einer Zentrale áufgerufen, um den momentanen aktuellen Standort abzufragen. Der Standort wird vom Fahrzeug durch ein Funktelegramm übermittelt, indem der zuletzt empfangene Ortscode und die seither gefahrene Strecke mitgeteilt,wird. Für die Strecke stehen dabei im Funktelegramm meist 8 Bit, also 256 Schritte, zur Verfügung. Daraus folgt, daß die vom Fahrzeug aufsummierten Ws g impulse zu Wegschritten aufintegriert werden müssen.emits an impulse every 1 m of travel. In computer-controlled transport control systems The vehicles in the system are called up cyclically from a control center in order to query current location. The location is determined by the vehicle through a Radio telegram transmitted by the last received location code and the one since the distance traveled is communicated. The radio telegram stands for the route mostly 8 bits, i.e. 256 steps, are available. It follows that from the vehicle summed up Ws g impulses have to be integrated into steps.
Es ist bekannt, einer Fahrzeuganlä;ge dazu einen festen Wegintegrationsfak:-or vorzugeben. Dieser stellt einen Kompromiß dar zwischen dem Aufwand an Ortscodeeinrichtungen, die den Wegimpuisgeber zurücknetzen, und der geforderten Auflösungsgenauigkeit bei der Standortbestimmung.It is known that a vehicle system has a fixed path integration factor for this purpose: -or to pretend. This represents a compromise between the cost of location code facilities, which network the Wegimpuisgeber back, and the required resolution accuracy the determination of the position.
Aufgabe der Erfindung ist es, eine -Anordnung anzugeben, bei der der Wegintegrationsfaktor während des Betriebs geändert werden kann, um die Auflösegenauigkeit der Standortbestimmung unterschiedlichen Anforderungen ansupassen.The object of the invention is to provide an arrangement in which the Path integration factor can be changed during operation to improve the resolution accuracy adapt to different requirements of the location determination.
Die Erfindungtst im Patentanspruch 1 beschrieben. Der Unteranspruch -beinhaltet eine vorteilhafte Weiterbildung der Erfindung.The invention is described in claim 1. The subclaim -includes an advantageous development of the invention.
Der bezondere Vorteil der Erfindung liegt darin, daß in einem Stadtkern mit, vielen dicht aufeinanderfolgenden Haltestellen, wo dte Standortbestimmung sehr genau sein muß-, ein kleiner Wegintegrationsfaktor gewählt werden kann, während bei Überladfahrten ein großer Faktor gewählt werden kann, damit trotz weiter Strecken die Anzahl der Ortscodeeinrichtun;gen gering bleiben kann. Busnetze- mit beiden Arten von Strecken in einer Linie kommen häufig vor.The particular advantage of the invention is that in a city center with, many stops in close succession, where the location is very much must be accurate, a small path integration factor can be chosen while A large factor can be selected for overload trips, so that despite long distances the number of local code facilities can remain small. Bus networks - with both Types of stretches in a line are common.
Die Erfindung wird im folgenden an einem Ausführungsbeispiel naher beschrieben.The invention is closer to an embodiment in the following described.
Auf der Route eines Fahrzeugs, z. B. eines Nahverkehrsbetriebes, seien in unterschiedlichen Abständen Ortscodeeinrichtungen angeordnet In FIG. 1 ist dargestellt, welchen Aufbau das Telegramm einer solchen Einrichtung haben kann.On the route of a vehicle, e.g. B. a local transport company Location code devices arranged at different distances In FIG. 1 is shown what structure the telegram of such a facility can have.
Auf einen Synchronisationsteil folgt ein erster Infoblock, in welchem u. a. Angaben über den technischen Zustand der Ortscodeeinrichtung enthalten sein können, sodann ein zweiter Infoblock, welcher die Ortscodeadresse angibt, also den momentanen Standort, und schließlich ein Redundanzanteil.A synchronization part is followed by a first information block in which i.a. Information about the technical condition of the location code device must be included can, then a second info block, which specifies the location code address, so the current location, and finally a redundancy component.
Die Tabelle 1 schlüsselt noch einmal auf, wie der erste Infoblock aufgebaut sein kann. Es sind zwei Bits, hier bS und 5 b6 vorgesehen, um dem Fahrzeug den zu wählende Wegintegrationsfaktor mitzuteilen. Gemäß den möglichen Bitkombinationen könnten vier Faktoren verschlüsselt werden. Im Beispiel sind nur drei Kombinationen belegt, nämlich die Zustände b), c) oder d) mit den Faktoren 16, 32 bzw. 64. Die vierte Bitkombination ist im Beispiel mit einer anderen Information belegt, dem Eichstreckenanfang. Diese Information löst in der Fahrzeuganlage einen Eichvorgang aus, auf den hier nicht näher eingegangen sei. Die Vorgabe eines Wegintegrationsfaktors fällt an dieser Ortscodeeinrichtung aus, das Fahrzeug wählt daher den seit der vorherigen Einrichtung gespeicherten Faktor.Table 1 breaks down again, like the first info block can be constructed. There are two bits, here bS and 5 b6, for the vehicle to communicate the path integration factor to be selected. According to the possible bit combinations four factors could be encoded. In the example there are only three combinations occupied, namely the states b), c) or d) with the factors 16, 32 or 64. The In the example, the fourth bit combination is occupied by a different piece of information, the Calibration route start. This information triggers a calibration process in the vehicle system which will not be discussed in detail here. The specification of a path integration factor fails at this location code device, the vehicle therefore selects the one since the previous one Facility stored factor.
Beim Ersteinschalten einer Fahrzeuganlage oder nach Batteriespannungs-Zusammenbruch hat der Fahrzeugrechner noch keinen Wegintegrationsfaktor gespeiche'rt. Er wählt daher selbständig einen bestimmten vorgegebenen Faktor, z. B. 32.When switching on a vehicle system for the first time or after a battery voltage breakdown the vehicle computer has not yet saved a path integration factor. He chooses therefore independently a certain predetermined factor, e.g. B. 32.
Dieser Faktor wird solange benutzt, bis eine Ortscodeeinrichtung einen neuen mitteilt.This factor is used until a location code device announces new.
Bei der Übertragung des Standortes an die Zentrale wird vom Fahrzeug als zurückgelegte Weglänge das geradzahlige abgerundete Ergebnis der Division ZWegimpulse = E Wegschritte Wegintegrationsfaktor mitgeteilt.When transferring the location to the headquarters, the vehicle the even-numbered rounded result of the division ZWegimpulse as the distance covered = E path steps path integration factor communicated.
