Abstract

PURPOSE:To control a lot of cars with a small number of radio channels by transmitting data, which are received by a radio communication means for control, from a stop side communication means to a car side radio communication means and transmitting data, which are received by a stop side radio communication means, from the radio communication means for control to a control facility. CONSTITUTION:A signal from a control center 21 is transferred from a stop control system 11 to a car side control system 1 and a signal from the car side control system 1 is transferred from the stop control system 11 to the control center 21. Then, the control of a bus is executed without direct communication between buses 1a, 1b... and the control center 21. Accordingly, the radio channel between the buses 1a, 1b... and control center 21 is eliminated. The communication is executed between car side radio equipments 5 and between the car side radio equipment 5 and a stop radio equipment. Then, the change of the fine data can be executed and especially, the information of passing are exchanged. Thus, the radio channel is economized and a lot of the cars can be controlled by a small number of channels.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a traffic control system for vehicles such as buses traveling on a predetermined route, and particularly to a traffic control system that saves wireless links between the control facility and the traffic control system. Related.

[Prior art]

Recently, buses and bus stops communicate wirelessly with the control center, and various data are sent from the bus and the bus stop to the control center, while the control center also sends various commands to the bus and the stops that the bus passes through. There are some things that are designed to emit.

When a trr command is issued from the control center, the lotus bus is allowed to travel in accordance with the command, while at the bus stop, the destination of the next lotus bus, waiting time, etc. are displayed on the display device.

[Problem to be solved by the invention]

By the way, in the above case, communication between the bus and the control center is carried out via a wireless line, but normally there are multiple buses operating on one route, and the communication between multiple buses and the control center is Multiple wireless channels are required to communicate between the two. However, the number of channels that are allowed to be used is usually limited and cannot be used freely. Therefore, when the number of buses increases, there is a problem that the number of channels becomes insufficient. Furthermore, since data is exchanged between the vehicles and the control center, there is a problem in that data such as the state of dumplings and overtaking conditions between vehicles cannot be accurately exchanged.

The present invention was devised in view of the above-mentioned circumstances, and provides a vehicle control system that can control a large number of vehicles with a small number of channels by saving wireless lines, and can perform more detailed control. This is what we are trying to provide.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a traffic control facility that controls vehicles running on a predetermined route by transmitting and receiving data between a traffic control facility that issues traffic orders and a bus stop, between a bus stop and a vehicle, and between vehicles. The control system includes, on the vehicle side, a vehicle fil+wireless communication means for communicating between vehicles and between stops, and a vehicle-side control means for controlling the transmission and reception of signals of the vehicle-side wireless communication means; , a stop side jIiE line communication means for communicating with the vehicle side wireless communication means, a control wireless communication means for communicating with the control facility, a control wireless communication means and a stop side wireless communication means. The control means is configured to transmit data received from the bus stop side wireless means to the vehicle side communication means, and from the control wireless means to the control facility.

[Effect]

According to the configuration of the present invention, communication is performed between the stop and the control facility via the control wireless communication means, and between the stop and the vehicle is communicated via the stop side wireless communication means. Communication is carried out via the vehicle-side radio communication means and the vehicle-side wireless communication means, and communication between the vehicles is interrupted and data is exchanged between the vehicles, but the control radio communication Data received by the means is transmitted from the stop side communication means to the vehicle side wireless communication means, and conversely, data received by the stop side wireless communication means is transmitted from the control wireless communication means to the control facility.
