Definitions
- the invention relates to a method for transmitting position data from Vehicles to a control center according to the preamble of claim 1.
- Accurate position data is primarily needed to ensure schedule conformity monitor and control stop displays, which is the expected waiting time until the vehicles arrive signal. For this purpose, they are especially odometric, using radio beacons or position data determined using GPS (Global Positioning System) the vehicles are queried successively and cyclically by a central office.
- GPS Global Positioning System
- WO 97/24626 A2 describes a system in which the distance traveled Monitored the path of one or more vehicles from a control center can be.
- Each vehicle is equipped with a satellite navigation device and a memory for storing determined Position data equipped with the current time. On request These stored data from the vehicle are sent to an interrogator downloaded.
- the position data of the vehicles are not in so-called real time in a central office.
- a problem with systems which enables real-time tracking of a variety of vehicles The task is that the received in a center Position data was generated at different times.
- the time delay between the individual queries creates a Distortion error that occurs during the first polled vehicle corresponds to the period of a distance covered by a query cycle and corresponds to approx. 0 for the last polled vehicle. That means, that the impression can arise in the central office that the first queried vehicles compared to the last queried vehicles have major delays.
- the time period required for a polling cycle is more than half Require minute.
- the invention has for its object the distortion error on simple Way and for any size of vehicle fleet, in particular also to be avoided in the event of an expansion of the vehicle fleet.
- the object is characterized by the features of claim 1 solved. It is particularly advantageous that the cyclical query the position data can be retained by the head office. Yet the cyclical successive query results in a snapshot, the the actual relationships of the positions of the vehicles to each other. The simultaneously determined and in are queried position data written in a memory. The mistake that gets through the duration of a query cycle is the same for all vehicles. This allows a correction to be carried out in a simple manner. For example, after each polling cycle, the position data of vehicles that are not about to stop or at the stop, add a distance of 200 m become. This distance corresponds to the average distance during the distance traveled for the query cycle.
- the memories are preferably designed as rewritable data memories of small storage capacity and of the simplest design.
- a series of vehicles F 1 , F 2 ... F n is shown , the number n of which forms a vehicle fleet which is monitored by a control center Z.
- Central Z serves, among other things, to transmit schedule and rerouting information as well as DGPS (Differential Global Positioning System) correction data to the vehicles.
- DGPS Different Global Positioning System
- the data available in the central office Z are also increasingly being used to control stop displays (not shown) for visualizing the remaining waiting time until the next vehicle F 1 , F 2 ... F n arrives. For these applications, it is necessary to know exact and time-conforming position data of the individual vehicles F 1 , F 2 ... F n .
- the central station Z asks for this position data in a polling process, ie the position data of the same time of the vehicles F 1 , F 2 ... F n are transmitted to the central station Z one after the other. So that all vehicles F 1 , F 2 ... F n report their position data to the central station Z at the same time, each vehicle F 1 , F 2 ... F n has a memory S 1 , S 2 ... S n fitted.
- the polling method has access to these memories S 1 , S 2 ... S n .
- / x n , y n are sent to the control center at the same time t 1 for all vehicles F 1 , F 2 ... F n Z reported.
- This fixed point in time t 1 can be realized, for example, in that the control center Z sends a trigger signal to all vehicles F 1 , F 2 ... F n immediately before the start of the next polling cycle, which leads to a current position determination by the vehicles F 1 , F 2 ... F n is activated.
- odometric methods in which the wheel axis revolutions are evaluated, radio beacon methods or GPS or DGPS (Global Positioning System or Differential Global Positioning System) methods are used for determining the position. If the vehicles F 1 , F 2 ...
- F n are equipped with GPS or DPGS receivers
- the derived system time which is absolutely the same for all GPS or DGPS receivers, can be used to determine a regular position determination in certain Intervals are used.
- the time intervals are matched to the length of the polling cycle and correspond exactly to the interval between two polling cycles.
- the activation method described above can be used by means of a trigger signal that is generated by the control center Z. This also has the advantage that the distance between two polling cycles does not necessarily have to be constant.
- a current image can be interpolated in a simple manner, for all vehicles F 1 , F 2 ... F n , the probably unimpeded free travel ahead have, which is added to the position data in the time difference ⁇ t on average covered distance.
- ⁇ t const. there is a fixed addition value.
- traffic-related or route-related peculiarities for example traffic congestion or a stop area, can be taken into account.
