Description

[Detailed explanation of the invention] [Summary] This is a traffic management system that uses taxis as mobile stations.
By automatically transmitting an unauthorized boarding signal from each taxi to the base station based on a combination of the presence or absence of passengers detected by sensors and whether the taxi is empty or an actual vehicle on the fare meter, the base station determines whether or not there is any unauthorized boarding. to be able to understand.

[Industrial application field]

The present invention relates to a traffic management system that allows a base station to detect unauthorized taxi rides.

[Conventional technology]

In a taxi operation management system using an AVM (automotive vehicle position monitor) system, each taxi is used as a mobile station and automatically transmits the operating status (current position, actual/vacant status, etc.) to a base station. The base station that received this signal uses the CRT11 as shown in Figure 3.
The status of each mobile station is displayed and used as a reference for vehicle allocation processing, etc.

At the mobile station, a signal indicating whether the vehicle is an actual vehicle or an empty vehicle is input from the fare meter 21 to a signal processor 22. Various data (position signals, etc.) from the key switch 23 are also input to this signal processor 22, and these data are transmitted to the radio device 2.
4 to transmit to the base station.

[Problem that the invention attempts to solve]

By the way, if a taxi driver picks up a passenger without tipping over the fare meter (illegal boarding), the current system cannot detect this because the base station only receives an empty car signal.

The present invention enables a base station to determine whether there is an unauthorized passenger by installing a sensor that can detect whether there is anyone other than the driver inside the taxi.

[Means for solving problems]

The present invention is characterized in that a taxi is used as a mobile station, and when the passenger detection means detects a passenger while the fare meter is outputting an empty car signal, it transmits an illegal boarding signal to the base station. It is something to do.

[Effect]

If a passenger is in the car during the period when the fare meter outputs an empty car signal, there is a possibility that the car is traveling with an illegal passenger on board, so the base station that receives the illegal boarding signal indicating this is an unauthorized person. To be able to reliably know which taxi you are boarding even in a remote location.

〔Example〕

FIG. 1 is a configuration diagram showing an embodiment of the present invention, and 2
Reference numeral 5 denotes a seat switch that can detect whether or not there is a passenger in a seat in the taxi. Specifically, it is a switch that is installed on the seat and is operated by pressure from the passenger's weight. Output B of this seat switch 25
is input to the signal processor 22 together with the output A of the fare meter 21 and the output of the key switch 23. The signal processor 22 combines the fare meter output A and the seat switch output B to create an unauthorized boarding signal C. FIG. 2 is a diagram of this waveform.

If the fare meter output A indicates an actual vehicle when the seat switch output B indicates that the vehicle is occupied, this means that the vehicle is in a normal operating state, and the unauthorized boarding signal C is at the normal level. Both outputs A and B are at the normal level even when there are no empty cars or passengers, respectively.

On the other hand, if the fare meter output A indicates that the vehicle is empty but the seat switch output B indicates that the vehicle is occupied, there is a possibility that the vehicle may have been boarded illegally. However, taking into account the time from when a passenger takes a seat until the fare meter is turned down and the invalid time when paying a fare, etc., a certain period of time τ
(For example, after 30 seconds have elapsed, the illegal boarding signal C is set to the illegal level.) Since this illegal boarding signal C is sent out automatically, the base station can monitor the driver's illegal behavior from the display on the CRT 11. In this embodiment, a seat switch is used as the passenger detection means, but it is also possible to use a light receiving/emitting element or an infrared sensor.

[Effect of idea]

As described above, the present invention has the advantage that by providing a passenger detection means such as a seat switch, it is possible to detect unauthorized taxi rides using the existing AVM system.
