Description

AUTOMATIC DEGRADATION METHOD AND SYSTEM FOR FULL ELECTRONIC

INTERLOCKING SIGNAL

TECHNICAL FIELD

[0001] The présent invention relates to the field of rail transport technology, and more particularly, to an automatic dégradation method and system for a full electronic interlocking signal.

BACKGROUND

[0002] The full electronic interlocking uses the signal control module instead of the traditional relay circuit to control clearing of the signal. The DS6-60 full electronic interlocking system adopts the prior mature interlocking computer of the DS6-60 system as the safe operation logic platform, and the full electronic modules (the signal module, the I swîtch module, the universal input output module) as the execution unit to complété direct control over signal devices, the system structure is shown in FIG. 1.

[0003] The interlocking computer (the safe logic operation computer) sends a control command to the execution unit, the signal module executes the command to control a light point of the signal to be lightened or extinguîshed, meanwhîle ît sends the clearing State of the signal to the interlocking computer. When the clearing State of the signal îs abnormal, for example, the interlocking computer requires the green light to be cleared by the signal, but the green light bulb cannot be lightened, the signal module will feed back to the interlocking computer that the green light cannot be lightened, the interlocking computer détermines that the State does not meet expectations and then it changes the control command. Usually the signal module and the interlocking computer use Ethernet to communicate, there is a certain delay in the information exchange process, the delay time may be relatively long when the communication is interfered, especially when the signal fails in the case where the ' prohibition light needs to be lightened urgently (such as lightening a red light point), a too long delay time will seriously reduce safety and availability of the system.

[0004] Therefore, how to control the signal to switch the signal State in time and improve safety and availability of the system has become an urgent problem to be solved.

[0039] The avaîlability dégradation further includes:

[0040] As used herein, the avaîlability dégradation means that the signal module actively performs avaîlability dégradation, which is suitable for scénarios that requîre a response speed for avaîlability dégradation.

[0041] Exemplarily, FIG. 5 shows a flowchart of actively performîng avaîlability dégradation according to an embodiment of the présent invention, as shown in FIG. 5:

S1 : the interlocking computer Controls to provide a signal clearing command plus a signal lower-level clearing command, so as to control the signal to clear;

[0042] The embodiment of the présent invention takes two signais as an example for description. Illustratively, FIG. 6 shows a schematic diagram of a System structure according to an embodiment of the présent invention. As shown in FIG. 6, there are five light points in the signal A, which sequentially are the yellow light point, the green light point, the red light point, the yellow light point, and the white light point; for railway lines having less information that need to indicate, the signal B can be used to direct traffic, there are three light points in the signal B, which sequentially are the green light point, the red light point, and the yellow light point. The interlocking computer sends commands and information to the signal module through the Ethernet, and the signal module Controls the light point in the signal to indicate through the cable.

[0043] It should be noted that light point setting of the above-described signal may also adopt other different types.

[0044] During abnormality protection dégradation:

[0045] Exemplarily, indication of both the green light and the yellow light being concurrently cleared by the signal A is taken as an example, after receiving the command from the interlocking computer, the signal module cuts off power supply of other light points, meanwhile it supplies power to the yellow light, supplies power to the green light after the yellow light is lightened. When both the green light and the yellow light are lîghtened, the signal module feeds back to the interlocking computer an indication state that the green light and the yellow light are already cleared by the signal, feeds back execution success of the command, feeds back information that the light point is normal. After the green light and the yellow light are lightened, the signal module continuously monitors lightening of the light point. If the yellow light is accidentally extinguished and the green light remains lightened, the signal module détermines that the signal indication is abnormal and there is a safety risk, power supply to the yellow light and the green light is stopped immédiately, power is supplied to the red light înstead, meanwhile the signal module feeds back to the interlocking computer an indication State that the red light is cleared by the signal A, feeds back execution failure of the command, feeds back information that the yellow light point has a failure, so as to realîze rapid protection agaînst dangerous failure. Correspondingly, the interlocking il computer receives the failure information, switches the signal command to a red light command, and alarms the operation and maintenance personnel at the same time. After the green light and the yellow light are lightened, the signal module continuously monitors lightening of the light point. If the green light is found to be accidentally extinguished and the yellow light remains lightened, the interlocking computer only performs a corresponding availability dégradation.

[0046] When the signal module passively performs availability dégradation:

[0047] Exemplarily, indication of the green light being cleared by the signal A is taken as an example, the yellow light is defined as a lower-level signal command of the green light in practical applications. After receivîng the command from the interlocking computer, the signal module cuts off power supply of other light points and meanwhile supplies power to the green light. After the green light is lightened, the signal module feeds back to the interlocking computer an indication state that the green light is already cleared by the signal, feeds back execution success of the command, feeds back information that the light point is normal. After the green light is lightened, the signal module continuously monitors lightening of the light point. If the green light is found to be accidentally extinguished, the signal module feeds back to the interlocking computer an indication state that the signal A stops, feeds back execution failure of the command, feeds back information that the green light point has a failure. The interlocking computer receives the failure information, switches the signal command to a lower-level yellow light command, and alarms the operation and maintenance personnel at the same time; after the signal module receives the yellow light command, the signal module cuts off power supply of the green light and supplies power to the yellow light înstead, after the yellow light is lightened, the signal module feeds back to the interlocking computer an indication state that the yellow light is already cleared by the signal, feeds back success execution of the command, and continues to feed back information that the green light has a failure. A wait time timing is set when the signal module is waiting for the interlocking computer to switch the command, the signal module actively lightens the prohibition light of the signal, the red light, if the interlocking computer does not switch the command after the timing ends.

[0048] When the signal module actively performs availability dégradation:

[0049] For scénarios that requîre a response speed of availability dégradation, when the interlocking computer sends a control command, it will also send a lower-level signal command as an additional command to the signal module, the signal module can directly and actîvely use the signal lower-level clearing command to lighten the new target light point.

[0050] Exemplarily, taking that the green light is cleared by the signal A as an example, the yellow light is defined as a lower-level signal command of the green light in practical applications. When the interlocking computer sends a green light clearing command to the signal module, it also sends a yellow light clearing command as an additional command to the signal module. After receîving the command from the interlocking computer, the signal module cuts off power supply of other light points and supplies power to the green light. After the green light is lightened, the signal module feeds back to the interlocking computer an indication State that the green light is already cleared by the signal, feeds back execution success of the command, feeds back information that the light point is normal. After the green light is lightened, the signal module continuously monitors lightening of the light point, the signal module will eut off power supply of the green light and start to supply power to the yellow light if the green light is found to be accidentally extinguished. After the yellow light is cleared, the signal module feeds back to the interlocking computer an indication State that the yellow light is cleared by the signal A, feeds back execution success of the command, feeds back information of that the green light point has a failure; the interlocking computer receives the signal information, switches the signal command to the lower-level yellow light command, and alarms the operation and maintenance personnel at the same time.

[0051] The présent invention further pro vides an auto marie dégradation System for a full electronic interlocking signal, as shown in FIG. 6, the System includes an interlocking computer, a signal module, and a signal, wherein the interlocking computer is for sending a control command to the signal module;

the signal is for signal indication.

[0052] Specifically, the interlocking computer and the signal module transmit information through the Ethernet, the interlocking computer sends control commands to the signal module through the Ethernet, the signal module feeds back an indication State cleared by the signal and auxiliary information to the interlocking computer through the Ethernet; the signal module is connected to the signal through the cable, and Controls the light point in the signal to be lightened or extinguished.

[0053] By differentiating the dégradation function, the présent invention makes a division into abnonnality protection dégradation and availability dégradation. For abnormality protection dégradation, respond can be made quickly when danger indication is found, which improves the processing speed and avoids the time delay caused by a System failure or extemal factors; for availability dégradation, dégradation response time is reduced through an additional command mode, which improves safety and availability.
