Embodiment Construction

[0020] Referring to the accompanying drawings, the train speed temporary limiting device of the present invention includes an information transmission path 1, ground devices 31-33, and a vehicle-mounted device 7. The information transmission road 1 is laid continuously along the line 5 across a plurality of train control sections D1-D4, and transmits a temporary instruction indicating that a certain area ΔP in the train control section D1-D4 should temporarily limit the train speed. Speed ​​limit information. exist figure 1 In the case of (A), the area ΔP is in the train control section D2 adjacent to the train control section D1, and is located between points P1 and P2 with the boundary of the train control section D1-D2 as a reference point P0.

[0021] The information transfer path 1 can be constituted by an already established LAN for transferring operation management information. The established LAN for transmitting the operation management information is originally a l...

Abstract

Provided is a temporary train speed-limiting device that keeps the cost advantage of a point-type automatic train stop system-pattern (ATP) device and is capable of executing a train speed-limiting operation in response, for example, to a sudden deterioration of weather conditions or infrastructure work such as railway track repair being performed. This temporary train speed-limiting device includes an information transmission line (1), ground-side devices (31-33), and an onboard device (7). The information transmission line (1) is laid along a railway track (5) across multiple train control areas (D1-D4). This information transmission line transmits temporary speed-limiting information indicating that the speed of a train should be temporarily limited in a specific zone ( P) of the train control areas. The ground devices are installed at each train control area and transmit the temporary speed-limiting information supplied from the information transmission line. Upon receiving the temporary speed-limiting information, the onboard device (7) generates a speed pattern based on a temporary train speed limit and controls the speed of the train so as not to exceed the speed specified by this speed pattern.

Description

technical field [0001] The invention relates to a train speed temporary limiting device for temporarily limiting the train speed. Background technique [0002] Conventionally, an ATC (Automatic Train Control: Automatic Train Control) device, a CBTC (Communications-Based Train Control: Communications-Based Train Control) system, etc. are known as train control techniques. In addition, a point type ATS-P (Automatic Train Stop system-Pattern: automatic train stop system pattern) system (hereinafter, abbreviated as point type ATP system) having a cost advantage over these systems is also known. [0003] In the point-type ATP system, as disclosed in Patent Document 1, for example, ground beacons are installed at predetermined intervals along the route on which the train travels, and speed limit information is transmitted through these ground beacons. By receiving this information with the vehicle-mounted device, a speed pattern based on the speed limit of the train is generated....
