Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle guidance device that provides occupancy rate information for each vehicle to passengers boarding each vehicle of a train.

[Prior Art] Seat occupancy detection means for detecting whether a seat is occupied, signal transmission means for transmitting and receiving the output of the occupancy detection means to and from other vehicles via rails, and information on vacant seat positions for each vehicle. An in-train vacant seat position display device with means for displaying information on all vehicles was developed in 1982.
It is described in Publication No. 20349.

[Problems to be Solved by the Invention] As mentioned above, in order to detect whether or not a seat is occupied, a complicated device is required, but the invention of this application has a simple configuration by significantly reducing the number of component parts. The purpose of this invention is to provide a guidance device for the following.

[Means for Solving the Problems] An information transmission device that is disposed in each of the cars of a train in which a plurality of cars are connected and is connected to each other, and that transmits and receives occupancy rate information for each car detected from the weight of each of the cars. and a display device disposed in each of the vehicles to display the occupancy rate information visually for passengers of each of the vehicles, wherein the weight of each of the vehicles is calculated based on the weight of the body of each vehicle and the trolley. A vehicle guidance device, characterized in that the pressure is measured by a pressure sensor attached to an air spring arranged between.

[Embodiment of the Invention] FIG. 1 shows an embodiment of the invention. In the figure,
1 is a track, 2 is a car body, 3 is each car body, a bogie supporting 2, 4 is an air spring disposed between the car body 2 and the bogie 3, and the above 2 to 4 form a vehicle 5 that can run on the track. Ru. A pressure sensor 6 is attached to the air spring 4 and converts air pressure corresponding to the weight of the vehicle 5 into an electrical signal. 7 is an A/D converter that converts the analog signal sent from the pressure sensor 6 into a digital signal and outputs the digital signal. 8 is a calculation unit that calculates the occupancy rate based on the air pressure signal sent from the A/D converter 7.

Here, the occupancy rate is calculated by dividing the increase in air pressure when a passenger gets on the vehicle 5 by the increase in air pressure due to the average weight of each passenger, with respect to the air pressure when the vehicle 5 is empty. It is calculated by dividing the number of passengers by the passenger capacity.

Reference numeral 9 denotes an information transmission device that collects the occupancy information of each vehicle 5 sent from the calculation section 8, synthesizes it, edits it, and outputs it. Reference numeral 10 denotes a transmission path connecting the information transmission devices 9 of each vehicle, and uses, for example, an optical fiber. 11 is a transmission control unit that receives the output of the information transmission device 9; 12 is a calculation unit that calculates the output of the transmission control unit 11; 13 is a display control unit that controls the output of the calculation unit 12; and 14 is the output of the display control 13. The display panel is configured to display occupancy rate information for each connected vehicle as shown in FIG. 2. Display device 1 in 11 to 14 above
5 is formed.

Next, the operation will be explained. For example, at a station on a line where a six-car train is operated, passengers boarding the next train to stop wait at their designated boarding positions, look inside the train while it is moving, and look inside the train until it stops.
Each person is riding in a vehicle that has been determined to have a grace period for boarding.

In a train in which passengers board each car 5 in this way, the weight of each car 5 is detected by each pressure sensor 6, the passenger rate is calculated by the calculation unit 8, and the passenger rate information is sent to the information transmission device 9. Rare. By this,
The information transmission devices 9 of each vehicle 5 mutually transmit occupancy rate information via the transmission path 10, and send the occupancy rate information of each vehicle 5 to the display device 15. The occupancy rate of each vehicle 5 is displayed on the display device 15 so that passengers can visually see it, as shown in FIG.

Based on the occupancy rate displayed on the display device 15 of each vehicle 5, the passenger compares the occupancy rate of the vehicle 5 in which he/she boarded and that of other vehicles 5, and determines whether the vehicle is moving while the vehicle is running or It becomes possible to transfer to the vehicle 5 with a lower occupancy rate at the stopping station.

In addition to the method of calculating vehicle weight in each vehicle, conversion of vehicle weight to occupancy rate is performed at the transmission terminal of each vehicle in the information transmission device, or at the central station that controls the tradition in the train, or even at the display device. It is also possible to perform this in the internal arithmetic unit.

[Effects of the Invention] As explained above, according to the present invention, a plurality of cars are arranged in each car of a connected train and connected to each other, and each car is detected from the weight of each car. A vehicle guidance device comprising: an information transmission device that transmits and receives occupancy rate information; and a display device that is disposed in each of the vehicles and displays the occupancy rate information so that passengers in each of the vehicles can see the occupancy rate information; Since the weight of each vehicle is measured by a pressure sensor attached to an air spring placed between the car body and the bogie, it is possible to significantly reduce the number of components and obtain a device with a simple construction. .
