Description

Technical Field

[0001] This invention belongs to the field of railway signal technology, specifically relating to a signal control device and a signal simulation device. Background Technology

[0002] In the current method of signal reconnection work at railway signal stations, after the reconnection of the existing signal is completed within the track maintenance window, the station duty officer is contacted to conduct signal opening tests on each light individually. Since multiple signals start simultaneously and the reconnection completion time is similar, the station duty officer's operation of opening the signal for each light individually takes a long time, requiring frequent signal opening and block procedures, which affects the efficiency of track maintenance window construction and testing. Furthermore, if a lighting failure occurs during the test, it will continuously affect the subsequent individual tests of the signal, resulting in a significant impact on track maintenance window organization and the workload of the station duty officer. In addition, when the railway signaling profession conducts individual tests on newly installed signals, AC220 power is usually borrowed to conduct lighting tests on each light individually on the distribution panel. During the test, lights are directly lit for those with outdoor signals installed, and bulbs are directly hung for those without signals. Therefore, it is impossible to effectively distinguish the power supply wiring of each light during the test, causing certain troubles for subsequent tests. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a signal control device and a signal simulation device to solve the problem that after the signal switches are switched during track maintenance windows, the signal controllers queue up waiting for the station duty officer to open the signal, which affects the efficiency of track maintenance window construction and testing.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: First, the present invention provides a signal control device, comprising: Power input interface for connecting an external power source; An AC power terminal includes a positive terminal and a negative terminal, both of which are connected to the power input interface. Multiple signal control units are provided, each including multiple self-locking push-button switches. Each self-locking push-button switch includes a button indicator light, a first normally open contact pair, a second normally open contact pair, and a third normally open contact pair. One end of the first normally open contact pair is connected in parallel to the positive terminal, and the other end is the positive terminal output. One end of the second normally open contact pair is connected in parallel to the negative terminal, and the other end is the negative terminal output. One end of the third normally open contact pair is connected to the first normally open contact pair, and the other end is connected to the second normally open contact pair. The button indicator light is connected in series between the third normally open contact pairs. When one of the self-locking push-button switches is pressed, the button indicator light on the self-locking push-button switch and the first normally open contact pair and the second normally open contact pair are simultaneously switched on and off.

[0005] Furthermore, the power input interface is located on the enclosure, the AC power terminal is located inside the enclosure, and the enclosure is provided with pluggable terminals, one end of which is connected to the positive terminal output and the negative terminal output.

[0006] Furthermore, the positive and negative terminal outputs are connected to the pluggable terminals via colored insulated wires, and the colors of each self-locking push-button switch, the button indicator light, and the connected colored insulated wires are the same.

[0007] Furthermore, one end of the pluggable terminal is connected to a signal splitter cable.

[0008] Furthermore, the power input interface includes a three-pin socket and a matching three-pin plug. The three-pin plug is connected to an external power source, and the three-pin socket is connected to an AC power terminal.

[0009] Furthermore, the pluggable terminal block is an aviation plug.

[0010] Furthermore, the multiple signal control units include an entry signal control unit, a first exit signal control unit, a shunting signal control unit, a second exit signal control unit, a route signal control unit, and / or a third exit signal control unit. Each of the entry signal control unit, the first exit signal control unit, the shunting signal control unit, the second exit signal control unit, the route signal control unit, and / or the third exit signal control unit includes several self-locking push-button switches connected in parallel to the AC power supply terminals.

[0011] Furthermore, the station entry signal control unit includes five self-locking push-button switches with colors sequentially yellow, green, red, yellow, and white; the first exit signal control unit includes three self-locking push-button switches with colors sequentially green, red, and white; the shunting signal control unit includes two self-locking push-button switches with colors sequentially white and blue; the second exit signal control unit includes four self-locking push-button switches with colors sequentially green, green, white, and red; the route signal control unit includes six self-locking push-button switches with colors sequentially yellow, green, red, yellow, white, and white; and the third exit signal control unit includes ten self-locking push-button switches with colors sequentially green, yellow, yellow, red, white, white, white, white, white, white, white.

[0012] The present invention also provides a signal simulating device, including the above-mentioned signal control device and a plurality of light-emitting display units. Each light-emitting display unit is used to simulate a light position of the signal simulating device. The positive and negative terminal outputs of each self-locking push button switch of the signal control device are connected to one of the light-emitting display units. When one of the self-locking push button switches is pressed, the button indicator light on it and the light-emitting display unit connected thereto are simultaneously switched on and off.

[0013] Furthermore, the light-emitting display unit is a light-emitting diode or a light bulb.

[0014] Because the present invention adopts the above technical solution, it has the following advantages and effects: The present invention provides a signal control device and a signal simulation device, which can conduct signal lighting tests outside of track maintenance windows. After the test is completed, it can ensure that the signal coupling test is successful on the first attempt. It does not occupy the existing track maintenance window quota, does not affect train operation, and does not affect existing equipment, thus ensuring train operation safety and the safety of existing equipment.

[0015] This invention provides a signal controller operating device and a signal controller simulation device. These devices allow for direct connection of new cable wiring, new outdoor boxes, and new signal controllers to the distribution panel for full-process circuit testing. They also accelerate signal controller testing within the designated testing window, improving testing efficiency and enabling more intuitive signal controller lighting tests. By directly outputting the corresponding light power supply to illuminate the corresponding signal controller's light, the problem of repeatedly opening the signal during interlocking tests is solved. This ensures normal output voltage for signal controller lighting during fault handling, improving the efficiency of signal controller lighting fault handling. Furthermore, the operating device can be miniaturized and assembled, fitting easily into a carrying case for convenient portability and use. It can be used simply by connecting to 220V AC mains power, eliminating the need for a separate power supply. Attached Figure Description

[0017] Figure 2 This is a schematic diagram of the control principle of the self-locking push-button switch in Example 1.

[0018] The attached diagram is labeled as follows: 1-AC power terminal, 2-power input interface, 3-button indicator light, 4-first normally open contact pair, 5-second normally open contact pair, 6-third normally open contact pair, 7-pluggable terminal block, 8-first lamp terminal block, 9-second lamp terminal block. Detailed Implementation

[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings to provide a clearer understanding of the purpose, features, and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are merely illustrative of the essential spirit of the technical solution of the present invention.

[0020] Example 1 like Figure 1 , Figure 2 As shown. This embodiment 1 provides a signal control device, including a housing, a power input interface 2, an AC power terminal 1, and multiple signal control units. The power input interface 2 is installed on the housing for connecting to an external power source. The AC power terminal 1 includes a positive terminal and a negative terminal, both of which are installed inside the housing. One end of the positive terminal and one end of the negative terminal are connected to the power input interface 2. Each signal control unit is used to connect the signal, and each self-locking push-button switch corresponds to control one type of signal light of the signal. Each signal control unit includes multiple self-locking push-button switches. Each self-locking push-button switch includes a button indicator light 3, a first normally open contact pair 4, a second normally open contact pair 5, and a third normally open contact pair 6. One end of the first normally open contact pair 4 is connected in parallel to the positive terminal, and the other end is the positive terminal output. One end of the second normally open contact pair 5 is connected in parallel to the negative terminal, and the other end is the negative terminal output. The positive terminal output and the negative terminal output are connected to the corresponding signal light of the signal. One end of the third normally open contact pair 6 is connected to the first normally open contact pair 4, and the other end is connected to the second normally open contact pair 5. The button indicator light 3 is connected in series between the third normally open contact pairs 6. Pressing one of the self-locking push-button switches causes the button indicator light 3 on the self-locking push-button switch and the first normally open contact pair 4 and the second normally open contact pair 5 to be simultaneously switched on and off. At this time, the button indicator light 3 of the pressed self-locking push-button switch and the corresponding signal light of the signal machine are simultaneously lit or turned off.

[0021] Specifically, the top of the enclosure is the control panel, the power input interface 2 is located on the side wall of the enclosure, and the AC power terminal 1 is located inside the enclosure and plugged into the power input interface 2. The power input interface 2 is used to connect to an external 220V AC power supply. Multiple self-locking push-button switches of each signal controller control unit are embedded side by side on the panel, and the button indicator lights 3 are located inside the self-locking push-button switches and exposed on the panel.

[0022] Each time a self-locking push button switch is pressed, only the pressed self-locking push button switch outputs 220V AC power, while the other self-locking push button switches have no output. At this time, only the button indicator light 3 of the pressed self-locking push button switch and the signal light of the signal machine connected to it are lit. Therefore, the lighting of the button indicator light 3 directly indicates that the corresponding signal light connected to the signal machine is also lit at this time.

[0023] Furthermore, the enclosure is equipped with a pluggable terminal block 7. One end of the pluggable terminal block 7 is connected to the positive terminal output and the negative terminal output. The pluggable terminal block 7 includes a female connector and a male connector, with the male connector plugged into the female connector. The female connector is fixed on the panel and connected to the AC power terminal, while the male connector is used to connect to the corresponding signal light of the signal device.

[0024] Furthermore, to facilitate the connection of distinguishing signal lights, the positive and negative terminal outputs are connected to pluggable terminals 7 via colored insulated wires. The color of each self-locking push-button switch, the color of the push-button indicator light 3, and the color of the colored insulated wire connected to it are the same.

[0025] Furthermore, one end of the male connector of the pluggable terminal block 7 is connected to a signal splitter cable, and the other end of the signal splitter cable is connected to the signal light of the signal controller.

[0026] As a preferred option, the pluggable terminal 7 is an aviation plug, which includes a female aviation plug and a male aviation plug. The positive and negative output terminals are connected to the female aviation plug, the male aviation plug is plugged into the female aviation plug, and the male aviation plug is connected to the signal distribution cable.

[0027] Furthermore, the power input interface 2 includes a three-pin T-shaped socket and a matching three-pin T-shaped plug. The three-pin T-shaped plug connects to an external power source, and the three-pin T-shaped socket connects to the AC power terminal 1. The three-pin T-shaped socket is equipped with a power indicator light circuit breaker to prevent short circuits and easily indicate whether the power is on or off.

[0028] Furthermore, the multiple signal control units include an entry signal control unit A, a first exit signal control unit B, a shunting signal control unit C, a second exit signal control unit D, a route signal control unit F, and / or a third exit signal control unit E. Each of the entry signal control unit A, the first exit signal control unit B, the shunting signal control unit C, the second exit signal control unit D, the route signal control unit F, and / or the third exit signal control unit E includes several self-locking push-button switches connected in parallel to the AC power supply terminal 1.

[0029] Specifically, the station entrance signal control unit A includes five self-locking push-button switches, which are connected in parallel to AC power terminal 1. The colors of the five self-locking push-button switches and their button indicator lights 3 are yellow, green, red, yellow, and white, respectively. The color combination of the station entrance signal control unit is five colors: yellow, green, red, yellow, and white.

[0030] The first departure signal control unit B includes three self-locking push-button switches, which are connected in parallel to AC power terminal 1. The colors of the three self-locking push-button switches and their indicator lights 3 are green, red, and white, respectively. The color combination of the first departure signal control unit is green, red, and white.

[0031] The shunting signal control unit C includes two self-locking push-button switches. The colors of the two self-locking push-button switches and the button indicator lights on them are white and blue, respectively. The color combination of the shunting signal control unit is white and blue.

[0032] The second departure signal control unit D includes four self-locking push-button switches. The colors of the four self-locking push-button switches and their indicator lights are green, green, white, and red, respectively. There is a blank button (not connected to the circuit) between the two green self-locking push-button switches. The color combination of the second departure signal control unit is four types: green, green, white, and red.

[0033] The route signal control unit F includes six self-locking push-button switches. The colors of the six self-locking push-button switches and their indicator lights are yellow, green, red, yellow, white and (shunting) white, respectively. The color combination of the route signal control unit is six colors: yellow, green, red, yellow, white and white.

[0034] The third departure signal control unit E includes four self-locking push-button switches or ten self-locking push-button switches. When there are four self-locking push-button switches, the color of the four self-locking push-button switches and the indicator lights on them are all white. The four self-locking push-button switches are used for direction control.

[0035] When there are ten self-locking push-button switches, the colors of six of these switches and their indicator lights are green-yellow, empty, yellow, red, white, and white, respectively. The wiring positions and methods of these six self-locking push-button switches (not shown in the diagram) are the same as those of the self-locking push-button switches in the route signal control unit F. In this case, the route signal control unit F is not needed, and the light color combination of the third departure signal control unit is six colors: green, yellow, empty, yellow, red, white, and white. The direction control color combination is four colors: white, white, white, and white.

[0036] The connection method of one of the self-locking push-button switches will be used as an example for explanation.

[0037] The positive and negative terminals of AC power terminal 1 are connected to power input interface 2 via leads. The first normally open contact pair 4 of the self-locking push-button switch includes a first terminal J2 and a second terminal J1. The first terminal J2 is connected to the positive terminal. The second normally open contact pair 5 includes a third terminal J4 and a fourth terminal J3. The third terminal J4 is connected to the negative terminal. The fourth terminal J3 is connected to the first lamp terminal 8 of the push-button indicator light 3. The third normally open contact pair 6 includes a fifth terminal J6 and a sixth terminal J5. The third terminal J4 and the sixth terminal J5 are connected. The sixth terminal J5 is connected to the second lamp terminal 9 of the push-button indicator light 3.

[0038] When the AC power is output normally, the 220V AC power supply is connected to the first terminal J2 and the third terminal J4 through the positive and negative terminals. When the self-locking push-button switch is pressed, the first terminal J2 and the second terminal J1 are connected, and the third terminal J4 and the fourth terminal J3 are connected. One path of the power supply goes through the first terminal J2 and the second terminal J1 to the pluggable terminal 7, and the other path goes through the third terminal J4 and the fourth terminal J3 to the pluggable terminal 7. The pluggable terminal 7 is connected to the signal light of the signal device and illuminates. At this time, the 220V AC power supply is connected to the first terminal J2 and the third terminal J4. One path goes through the first terminal J2 and the second terminal J1 to the first light terminal 8 of the push-button indicator light 3, and the other path goes through the third terminal J4, the fourth terminal J3, and the sixth terminal J5 to the second light terminal 9 of the push-button indicator light 3, illuminating the push-button indicator light 3.

[0039] Because the button indicator light 3 passes through a set of closed contacts, it can prevent the power supply of the button indicator light 3 from being mistakenly introduced into the terminal of the other button indicator light 3 through the common return line when controlling one button indicator light 3.

[0040] The signal control principle of Example 1 is as follows: AC power is connected to the first terminal J2 and the third terminal J4 of the self-locking push-button switch. At this time, the self-locking push-button switch is not pressed, and the three normally open contacts of the self-locking push-button switch are in the open state and cannot output power. After the self-locking push-button switch is pressed, the positive terminal closes through the first terminal J2 to connect to the second terminal J1, and the negative terminal closes through the third terminal J4 to connect to the fourth terminal J3. At this time, 220V AC power is output to illuminate the signal lights of the outdoor signal.

[0041] Example 2 Example 2 provides a signal simulating device, including a housing, a power input interface, AC power terminals, and multiple signal control units. The housing, power input interface, AC power terminals, and multiple signal control units are the same as in Example 1. The difference from Example 1 is that Example 2 also includes multiple light-emitting display units. Each light-emitting display unit simulates one light position of a signal simulating a signal. The positive and negative terminal outputs of each self-locking push-button switch of each signal control unit are connected to one of the light-emitting display units. Pressing one of the self-locking push-button switches simultaneously turns the button indicator light on it and the corresponding light-emitting display unit on it on and off.

[0042] Furthermore, when the pluggable terminal block is an aviation plug, the male end of the aviation plug is connected to the corresponding light-emitting display unit.

[0043] As a preferred embodiment, the light-emitting display unit is a light-emitting diode or a light bulb.

[0044] When the signal simulation device in Example 2 is in use, the signal simulation device controls the light-emitting display unit through indoor interlocking control or signal operation device, and the signal simulation device provides feedback on the lighting status.
