Abstract
The invention relates to an axle counting automatic interspost block system which is a train operation safety safeguard system applied to a single track railway section. Axle counting wheel detectors are additionally mounted between stations to serve as dividing points to divide the operation line into two or numerous interpost sections; juxtaposition block post block signals are arranged at the uplink and the downlink of the block posts; the axle counting wheel detectors are arranged at the block post block signals; the axle counting devices are used for inspecting the occupation state and the idle state of the interpost sections; approach continuous cab signalling and distant signals are arranged at the distant signals; automatic block track circuit devices are applied to approach track sections to provide coded information for cab signals and can serve as the counting axle to remove judgement basis of +/-1 axle and prevent advanced deblocking of the system, the effective operating distance of the cab signals is no less than 1200m; the dividing points are confirmed to be unmanned wiring-free block posts; equipment service rooms are arranged at the block posts for placing devices such as the counting axles, the track circuits and power supplies; through cables are arranged between two train stations and the section dividing points for transmitting axle counting information and directional circuit safety information; and relay combination circuits are arranged at the train stations to realize functions such as switching between the directional circuits, signal control and the like. The axle counting interpost block is a basic block method, after the axle counting automatic interpost block system is out of service due to failures, operation according to the 64D semiautomatic block method is applied between stations; and when the 64D semiautomatic block method fails or the 64D equipment encounters failure, operation according to the telephone block method is adopted.
Description
Affiliated field: the present invention is applied in railway systems, belongs to the traffic safety control system.
Background technology: along with the great-leap-forward development of Chinese Railway, will serve as theme, and push forward technology innovation and system innovation comprehensively to improve transport capacity and lift technique equipment.Particularly CTC (centralized traffic control) builds the quickening day by day of process, and the demand that Semi-automatic Block District is realized taking inspection is more and more urgent.Clear and definite in " Ministry of Railways's Major Technical Policies " of (2004) No. 78 file distribution of iron science and technology: " the single line Semi-automatic Block District should be improved shuttle train and take safety inspection equipment, realizes inaccessible between the station automatically ".At present, China railways single line section accounts for 2/3, its interval 64D type all-relay semi-automatic block system that adopts mostly.This block equipment is adapted to that China single-track railway distance between sites is short, train moves in pairs and follow the trail of the little operating line of coefficient, guarantee traffic safety, improve conevying efficiency, the aspect such as improve working conditions brought into play remarkable effect.But more than 15km, even reach 40km～50km for some single line section length, adopt 64D type all-relay semi-automatic block system tissue to drive a vehicle, can not satisfy current freight volume demand.
For the demand, we have developed the technical solution of " meter shaft is block system between institute automatically " raising capacity.This scheme is at a kind of obturation modes of non-automatic block district based on the principle development of the meter axle and the direction circuit that automatically closes up, a kind of investment that is solution non-automatic block district transport capacity anxiety is little, the effective technology measure of instant effect is the important component part of control travelling facility.
Summary of the invention: block system is to use tricks a wheel sensor as train spacing point between the station between the automatic institute of meter axle, be divided into two or more block section between posts, train spacing point is equivalent to unmanned circuit place circuit uplink and downlink of living in and establishes and put signal that circuit passes through, and by the signal place meter axle wheel sensor is set in circuit institute, utilize axis-counting device to check taking of each block section between posts and idle condition.Arrange near continuous type cab signaling and distant signal by semaphore foreign side at circuit, adopt the track circuit equipment that automatically closes up near track section, for cab signal provides coding information, and can remove as meter shaft ± basis for estimation that 1 axle disturbs, anti-locking system shifts to an earlier date release, and the cab signal effective working distance is not less than 1200m; Separation is defined as unmanned no wiring line institute, at the set equipment back shop of circuit, for laying the equipment such as meter shaft, track circuit and power supply; Between two stations and the interval separation perforation optical cable is set, is used for transmitting axle information and direction circuit security information; Relay combinative circuit is established at the station, realizes the functions such as direction circuit, signal controlling switching.Meter shaft automatically between institute obturation be basic block system, meter shaft automatic between block equipment Out of order after, change between standing by 64D semiautomatic block method and drive a vehicle; When switching the semi-automatic unsuccessful or 64D equipment fault of 64D, press telephone blocking method between standing and drive a vehicle.
Adopt automatically block system between institute of meter shaft, set up in the interval unmanned no wiring line few, the construction period weak point of formula investing, instant effect.
