Embodiment 1

[0021] figure 1 , figure 2 It is a schematic diagram of the safety control method for electric rail transit. is the first preferred embodiment of the method of the present invention.

[0022] Such as figure 1 As shown, according to the method of the present invention, at first, according to the train operation diagram and the speed of a vehicle, the power rail is divided into a plurality of sections 3 with a certain basic length, preferably, the lengths of each section 3 are equal; A section system 1 is set at a certain position of the section; an on-board system 2 is set on an electric locomotive 4 running on the track, and the section system 1 is matched with the on-board system 2; when the locomotive runs through the n section When the section system is 1, the on-board system 2 cooperates with the section system 1 of the n section to trigger the power supply after the section system is cut off, and cut off the power supply of the adjacent n-1 sections that the locomotiv...

Embodiment 2

[0028] figure 2 It is a schematic diagram of a safety control method and system for electric rail transit. It is the second preferred embodiment of the present invention.

[0029] figure 1 , 2 The shown embodiment 2 is a further modification of the method in embodiment 1 in the method of the present invention. In this implementation, the trigger switch (C) 121 is optimized for the track trigger system 12, preferably, the trigger switch (C) 121 is made up of 3 switches K, and the trigger switch (C) of the vehicle system ’ )211 is composed of 3 trigger switches K ’ 2111 composition, 3 switches 1211 (K 1 K 2 K 3 ) work at the same time to control the power supply control switch (Q) 1111 to work, for example: when the trigger switch C of the n section n The 3 trigger switches 1211 (K 1 K 2 K 3 ) is triggered at the same time to connect, the power supply control switch Q of the previous section of this section n-1 will be disconnected, the power supply control switch Q...

Embodiment 3

[0037] image 3 , 4 It is a schematic diagram of the safety control system for electric rail transit.

[0038] A scheme of electric rail traffic safety control system: the system is composed of an on-board system installed on the locomotive body of an electric vehicle and a section system installed on a section of an electric rail, and the on-board system is connected to the section The system matches the power supply and power failure of the control section.

[0039] Preferably, the section system includes a power supply system and a track trigger system, the vehicle-mounted system includes a vehicle-mounted trigger system, and the track trigger system matches the vehicle-mounted trigger system. The power supply system includes a power cable, a power supply slide wire, and a power supply control system. The power supply control device of the power supply control system has a power supply control switch 1111 (Q), which is associated with the power supply slide wire, and the...

Abstract

The invention provides a safety control method for an electric rail transit. The method comprises the steps that an electric rail is divided into a plurality of sections with definite lengths according to a train graph and the train speed; a section system is arranged in a certain position of each section; an on-board system is arranged on an electric locomotive operating on the rail; the section systems are matched with the on-board system; and when the locomotive passes through the section system of the nth section, the on-board system is matched with the section system of the nth section to trigger the section system to supply power after outage. The invention further provides a safety control system for the electric rail transit. The system consists of the on-board system arranged on an electric locomotive body, and the section systems arranged on the sections of the electric rail, wherein the on-board system is matched with the section systems to control power supply and outage of the sections. According to the safety control method and the safety control system, the mode of the power supply after the outage by sections is adopted for controlling the locomotive on the electric rail to keep a safety distance from the locomotive ahead all the time in an operation process; potential safety hazards caused by human errors and equipment failures are eliminated thoroughly; and major accidents are avoided effectively.

Description

technical field [0001] The invention relates to a rail traffic safety control method and system thereof, in particular to a power rail traffic safety control method and system thereof. Background technique [0002] The existing rail traffic safety control methods are mostly realized through the control of signal lights, wired or wireless control, and alarm signal control. By artificially controlling the signal, the driver determines the next step for the control of the rail vehicle according to the meaning expressed by the signal, that is, the usual red light stop, green light and other prescribed signals. Such a safety control system relies on manual control and equipment. Reliability cannot effectively avoid traffic accidents caused by human errors of signal operators and rail vehicle drivers or equipment failures. In order to effectively guarantee the safety of rail traffic, it is necessary to improve the existing technology, especially for high-speed rail traffic, it is...
