To process all L
It has a high-speed signal processing device that grasps the exact position of the RT and outputs processed information to the LRT via a wireless repeater. The high-speed signal processing device, when receiving a request to shift from the LRT to the high-speed traveling that has arrived in the high-speed traveling section, based on the position of the request transmission LRT, the distance to the front LRT, the distance to the stop, and the gradient of the traveling section. Check the conditions for high-speed driving, such as geographical speed regulation conditions such as roads and curves,
It is determined whether or not high-speed traveling is possible. If it is determined that high-speed traveling is possible, a high-speed traveling signal is output to the LRT.

According to a second aspect of the present invention, in the first aspect, when the LRT that has received the high-speed traveling signal exits the high-speed traveling section, the LRT is canceled by the high-speed traveling cancellation signal output from the high-speed signal processing device. Alternatively, the traveling distance is compared with the high-speed traveling end position included in the high-speed traveling signal, and upon arrival at the high-speed traveling end position, the high-speed traveling signal is canceled by itself.

[0007]

An embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes an LRT, which travels on a rail while stopping at a plurality of stops 2 provided at predetermined positions on the ground near a line section. The LRT 1 is equipped with an in-vehicle device. This in-vehicle device is GPS (Global Posit
Ioning System) GPS receiver and its antenna 4 for detecting the position of the LRT 1 using the satellite 3, a wireless transceiver for transmitting and receiving information between the vehicle and the ground and its antenna 5, and display of a high-speed running signal, etc. It comprises a display input device 6, a processing circuit 7 for performing processing on the vehicle, and the like. Reference numeral 10 denotes a wireless repeater, which is provided at a predetermined position on the ground near the line section, similarly to the stop 2. The wireless repeater 10 includes a wireless transceiver 11 for transmitting and receiving information between the vehicle and the ground, a high-speed signal processing device 16 of an operation management center 15 described later, and an information transmitting device 12 for transmitting information. .

Reference numeral 15 denotes an operation management center for managing the LRT 1 in the line section, in which a high-speed signal processing device 16 is provided. The high-speed signal processing device 16 is a processing circuit 17 for transmitting information to and from the wireless repeater 12 and performing processing related to LRT operation control such as high-speed traveling determination processing, and a monitoring device for displaying the position of the LRT 1 in the line section and the operation status. 18, etc. The processing circuit 7 of the above-described LRT 1 and the processing circuit 17 of the high-speed signal processing device 16 are basically composed of general-purpose electronic devices such as computers, and check the security of various information.
If a failure is detected, the fail-safe configuration cancels the high-speed progress signal.

Next, the operation will be described. The running LRT 1 is constantly operated by the position detection system using the GPS satellites 3.
The position is detected, and the information is output to the high-speed signal processing device 16 of the operation management center 15 via the information transmission device 12 of the wireless repeater 10 near the LRT 1. The high-speed signal processing device 16 verifies whether the position information detected by the GPS satellite 3 indicates a correct position based on the installation position of the wireless repeater 12 that has received the position information and the geographical information of the line section. As a result, the accurate traveling positions of all the LRTs 1 in the line section are grasped.

[0010] The LRT 1 for normal traveling is driven mainly by the visual confirmation of the driver as in the past, but when it comes to a section where high-speed traveling is possible, such as entering a dedicated track section or traveling in a suburban area, Ask if you can drive faster than above. This information is output to the high-speed signal processing device 16 via the information transmission device 12 of the wireless repeater 10 near the LRT 1. In the high-speed signal processing device 16, based on the position of the request transmission LRT,
High-speed running conditions such as the distance from the front LRT 1, the distance to the stop 2, and the geographical speed regulation conditions such as the slope and curve of the running section are checked to determine whether high-speed running is possible.
When it is determined that high-speed traveling is possible, a high-speed traveling signal is output to the LRT 1. In the LRT1, check of transmission check code, comparison and comparison of destination vehicle number and own vehicle number,
After checking the safety of information such as the presence or absence of a request, a high-speed progress signal is displayed on the display / input unit 6 to instruct the driver to shift to high-speed running. Therefore, the driver of the LRT 1 performs high-speed traveling after confirming this display. The LRT 1 that has received the high-speed progress signal queries the high-speed signal processing device 16 at the timing of outputting the GSP position information and refreshes the high-speed progress signal.

When a high-speed traveling permission condition is lost, such as advancing from the high-speed traveling section, approaching the stop 2, or shortening the distance from the front LRT 1, the high-speed signal processor 16 outputs a high-speed traveling cancel signal to the LRT. The high-speed traveling signal is immediately canceled, and the LRT 1 emits an alarm sound to instruct the driver to shift to normal traveling by deceleration. Alternatively, when the LRT 1 compares the high-speed traveling end position included in the high-speed traveling signal with the traveling distance, and arrives at the high-speed traveling end position,
Cancel the high-speed progress signal by itself. Also in this case, a warning sound is issued and the driver is instructed to shift to normal running by deceleration.
