[0030] Through the above embodiments of the present invention, the power supply, fuses, and cables shared by the lighting circuits of the advance signal and the entry signal can be completely separated. By connecting the two lighting circuits to the two signals respectively, the lighting circuits of the advance signal and the entry signal are completely independent and do not affect each other. This achieves the technical effect of reducing the XJF220 power fuse breakage failure when the entry signal opens two permission signals, thus improving train safety. In addition, it solves the technical problem in the related art that the lighting system of the signal has fuse breakage failure, resulting in low train operation safety.

[0031] Optionally, in the above embodiments of the present invention, the first power supply terminal includes: a first power contact and a second power contact, the first power contact being connected to a first end of the first power supply, and the second power contact being connected to a second end of the first power supply. The first lighting circuit further includes: a first fuse connected between the first power contact and the first signal lamp terminal; and a second fuse connected between the second power contact and the first signal lamp terminal.

For example, the first end of the first power supply can be the live wire, and the second end of the first power supply can be the neutral wire.

[0033] Optionally, the capacity of the first and second fuses mentioned above is 0.5A.

[0034] In one alternative embodiment, such as Figure 2 As shown, a separate warning signal fuse RD can be installed on each branch of the warning signal lighting circuit (i.e., the first lighting circuit 10 mentioned above), namely the first fuse RD1 and the second fuse RD2, with a rated capacity of 0.5A. The first fuse RD1 is connected between the XJZ220 contact and the first signal light terminal, and the second fuse RD2 is connected between the XJF220 contact and the first signal light terminal.

[0035] Optionally, in the above embodiments of the present invention, the first signal light terminal includes: a first signal light contact, a second signal light contact, and a third signal light contact. The first and second signal light contacts are connected to a first fuse, and the third signal light contact is connected to a second fuse. The first lighting circuit further includes: a first relay, the first port of the first relay is connected to the first fuse, the second port of the first relay is connected to the first signal light contact, and the third port of the first relay is connected to the second signal light contact.

[0036] The aforementioned first relay can be a signal relay on the power supply side of the XJZ220 in the warning signal lighting circuit, such as... Figure 2 As shown, it could be a relay LXJF2.

[0037] In one alternative embodiment, such as Figure 2 As shown, for a warning signal controller, its XB box may include three interfaces: interface 1, interface 2, and interface 3. Interface 1 is connected to the first signal light contact, interface 2 is connected to the second signal light contact, and interface 3 is connected to the third signal light contact. The first port of relay LXJF2 can be connected to the XJZ220 contact via fuse RD1, the second port of relay LXJF2 can be connected to the first signal light contact, and the third port of relay LXJF2 can be connected to the second signal light contact. When relay LXJF2 is energized, the first and second ports of relay LXJF2 are closed; when relay LXJF2 is de-energized, the first and third ports of relay LXJF2 are closed.

[0038] Optionally, in the above embodiments of the present invention, the first lighting circuit further includes: a second relay, the first port of the second relay being connected to the first fuse, and the second port of the second relay being connected to the first port of the first relay.

[0039] The aforementioned second relay can be a filament relay added to the XJZ220 power supply side of the warning signal lighting circuit, such as... Figure 2 As shown, it could be a filament relay DJ, model JZXC-H18.

[0040] In one alternative embodiment, such as Figure 2 As shown, the filament relay DJ can be connected in series between the fuse RD1 and the first port of the relay LXJF2. When the filament relay DJ is energized, the filament relay DJ is turned on; when the filament relay DJ is de-energized, the filament relay DJ is turned off.

[0041] Optionally, in the above embodiments of the present invention, the system further includes: a detection device for detecting the electrical characteristics of the second relay; a processor connected to the detection device for determining whether the second relay has malfunctioned based on the electrical characteristics output by the detection device; and an output device connected to the processor for outputting a prompt message when the second relay malfunctions.

[0042] The aforementioned detection device can be any device set up according to detection needs, such as a voltage detection device, a current detection device, an action detection device, etc., but is not limited to these. The processor can be a microcontroller, an integrated circuit, etc., but is not limited to these. The output device can be a display screen, a speaker, etc., on the signal controller control panel, but is not limited to these. The prompting information can be information indicating to electrical maintenance personnel which filament relay DJ has malfunctioned, and can include identification information such as the serial number of the malfunctioning filament relay DJ.

[0043] In one alternative embodiment, the electrical characteristics of the filament relay DJ can be incorporated into the computer monitoring system and the electrical signal equipment testing management. The computer monitoring data and the electrical performance indicators of the warning signal lighting circuit are analyzed regularly to determine whether the filament relay DJ is faulty. If a fault is found, a prompt message can be displayed to notify the electrical maintenance personnel to go to the site immediately to handle the faulty relay.

[0044] Optionally, in the above embodiments of the present invention, the system further includes: a display repeater disposed on the control panel of the signal machine; the first lighting circuit further includes: a third power contact connected to the second power supply and the fourth contact of the first relay; a fourth power contact connected to the third power supply and the third port of the second relay; wherein, the fifth contact of the first relay is connected to the fourth contact of the second relay, the fifth contact of the second relay is connected to the first end of the display repeater, and the second end of the display repeater is connected to the second power supply.

[0045] The aforementioned control console can be the control console in the electrical centralized station operations room or the control display screen in the computer interlocking station train operation room, but is not limited to these. The display repeater can be, for example... Figure 2 The light bulb L shown can be, for example, a light bulb of a specific color such as yellow, green, or red, but is not limited to this. The third power contact can be as follows: Figure 2 The fourth power contact, as shown in the JZ contact diagram, can be as follows: Figure 2 The SJZ contact shown indicates that the second and third power supplies can be DC power supplies with different rated voltages. The JZ contact can be connected to the positive terminal of the second power supply, and the SJZ contact can be connected to the negative terminal of the second power supply. The second terminal of the display repeater is connected to the negative terminal of the second power supply.

[0046] In semi-automatic block sections, the display status of advance warning signals for each receiving direction at the station cannot be monitored in real time on the control console in the electrically centralized station operations room and the control display screen in the computer-interlocked station operations room. When both the main and auxiliary filaments of the yellow and green lights of the advance warning signals are broken, the control console in the electrically centralized station operations room and the control display screen in the computer-interlocked station operations room will not issue an alarm display indicating the double filament breakage of the advance warning signals. This makes it difficult for station operators to prompt signal maintenance personnel to replace the faulty bulbs in a timely manner. As a result, the advance warning signals may go out when the entry signal displays the entry stop or pass signal. In other words, the display status of the advance warning signals may be inconsistent with the display of the entry signals and the locomotive signal display in the section approaching the entry signal, affecting the normal operation of trains in motion and, in special circumstances, even endangering train safety.

[0047] To address the aforementioned issues, in one optional embodiment, a repeater for the advance signal can be installed on the control console and computer-controlled interlocking station display screen to effectively monitor the lighting status of the advance signal. When both the main and auxiliary filaments of the yellow or green light bulb of the advance signal are broken, the repeater on the control console and computer-controlled interlocking display screen will issue a flashing alarm, prompting electrical maintenance personnel to immediately replace the faulty bulb on-site.

[0048] Optionally, in the above embodiments of the present invention, the second power supply terminal includes: a fifth power contact and a sixth power contact, the fifth power contact being connected to the first terminal of the first power supply, and the sixth power contact being connected to the second terminal of the first power supply. The second lighting circuit further includes: a third fuse connected between the sixth power contact and the second signal lamp terminal, wherein the third fuse has a capacity of 1A.

[0049] The fifth power contact mentioned above can be an XJZ220 contact, the sixth power contact can be an XJF220 contact, and the third fuse can be the XJF200 power supply side fuse RD3.

[0050] In the LXZ combination of the entry signal, the fuse RD3 on the XJF220 power supply side has the same capacity as the fuse RD1 on the XJZ220 power supply side of the 1U, L lighting circuit and the fuse RD2 on the XJZ220 power supply side of the 2U, YB lighting circuit, both being 0.5A. When the entry signal simultaneously displays two permissive lights and the advance signal displays one permissive light, the XJF220 power supply fuse RD3 frequently fails, causing the already opened entry signal to be restarted and affecting train operation.

[0051] In one alternative embodiment, the capacity of the fuse RD3 on the power supply side of the XJF220 in the entrance signal lighting circuit is increased from 0.5A to 1A, reducing the risk of fuse RD3 breaking when the entrance signal opens two permission signals.

[0052] Optionally, in the above embodiments of the present invention, the system further includes: a data acquisition device for acquiring train status; and a control circuit connected to the data acquisition device, the first lighting circuit, and the second lighting circuit for controlling the on / off state of the first lighting circuit and the second lighting circuit based on the train status.

[0053] The aforementioned data acquisition device can be any device capable of acquiring the train's running status. The train status can be the train's running state, such as running, stopping at a station, or passing through, but is not limited to these. The control circuit can be an integrated circuit, a microcontroller, etc., but is not limited to these.

[0054] In an optional embodiment, in order to ensure that the display status of the entry signal and the advance signal are consistent with the train's running status, the train status can be collected by a data acquisition device, and the on / off state of the first lighting circuit and the second lighting circuit can be controlled by a control circuit. Specifically, the energization and de-energization of different relays in the first lighting circuit and the second lighting circuit can be controlled, thereby controlling the light bulbs of different colors in the entry signal and the advance signal to light up.

[0056] According to an embodiment of the present invention, a control method for a signal controller is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions.

The first lighting circuit includes a first power supply terminal and a first signal light terminal, the first power supply terminal being connected to a first power source and the first signal light terminal being connected to the warning signal; the second lighting circuit includes a second power supply terminal and a second signal light terminal, the second power supply terminal being connected to a first power source and the second signal light terminal being connected to the entry signal.

[0058] The first power supply mentioned above can be a 220V AC power supply.

[0060] Step S302: Obtain train status.

[0061] The train status in the above steps can be the train's running status, such as running, stopping at a station, or passing through, but it is not limited to these.

[0062] Step S304: Control the on / off state of the first and second lighting circuits based on the train status.

[0063] In an optional embodiment, in order to ensure that the display status of the entry signal and the advance signal are consistent with the train's running status, the train status can be collected by a data acquisition device, and the on / off state of the first lighting circuit and the second lighting circuit can be controlled by a control circuit. Specifically, the energization and de-energization of different relays in the first lighting circuit and the second lighting circuit can be controlled, thereby controlling the light bulbs of different colors in the entry signal and the advance signal to light up.

[0064] Through the above embodiments of the present invention, the power supply, fuses, and cables shared by the lighting circuits of the advance signal and the entry signal can be completely separated. By connecting the two lighting circuits to the two signals respectively, the lighting circuits of the advance signal and the entry signal are completely independent and do not affect each other. This achieves the technical effect of reducing the XJF220 power fuse breakage failure when the entry signal opens two permission signals, thus improving train safety.
