The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Also, in the description of the present invention, the terms "first", "second", and the like are used for distinguishing between descriptions and not necessarily for describing a relative importance or implying any actual relationship or order between such entities or operations.
The invention is realized by the following technical scheme that the railway signal control comprises the control of indoor equipment and the control of outdoor equipment, the interlocking machine is the indoor equipment, and when the indoor equipment is built and the outdoor equipment is not built or built, the indoor equipment needs to be debugged in advance, so that the scheme is used for simulating the outdoor equipment, and the outdoor equipment simulation control box provided by the scheme is controlled by the upper computer, so that the indoor interlocking machine is debugged.
The invention provides a railway signal outdoor equipment simulation control box which is connected with an indoor interlocking machine through a distribution board. The main control box and the expansion control box simulate the working state of the outdoor equipment according to the control instruction of the upper computer, and feed back the simulation signals to the upper computer and the interlocking machine for display, if the simulation signals displayed by the upper computer are inconsistent with the simulation signals displayed by the interlocking machine, the fault points are described, and the fault points can be the line problem of the interlocking machine, the line problem of the connection between the outdoor equipment simulation control box and the interlocking machine, and the like. And then the interlocking machine is debugged to ensure that the interlocking machine can be directly used for controlling the outdoor equipment after the outdoor equipment is completely built in the future.
Please refer to fig. 1, which is a cascading manner of a main control box and a plurality of extension control boxes, where the main control box is installed with an extension interface, the extension control box is installed with two extension interfaces, the main control box is connected with the extension interface of the extension control box through the extension interface, the other extension interface of the extension control box is connected with the extension interface of the next extension control box, and so on, the plurality of extension control boxes can be cascaded.
As another possible implementation, the main control box may be installed with a plurality of expansion interfaces, each expansion control box is installed with an expansion interface, and the expansion control boxes are connected with the expansion interfaces on the main control box in a one-to-one correspondence manner through the expansion interfaces. However, the number of the expansion interfaces on the main control box cannot be reasonably set by the scheme, because the required number of the expansion control boxes is not necessarily the same at different railway stations, some large railway stations even need hundreds of expansion control boxes, and some small railway stations may only need one expansion control box or even no expansion control box. Therefore, if all the expansion control boxes are directly connected with the main control box, the main control box cannot evaluate how many expansion interfaces are properly installed in the production and manufacturing stage, if the number of the expansion interfaces is too large, the cost is increased, the size of the main control box is increased, and other problems are caused.
Therefore, the expansion control box is connected with the main control box in a cascading mode, only one expansion interface needs to be installed on the main control box, only two expansion interfaces need to be installed on the expansion control box, and when a large number of outdoor equipment needs to be simulated in a large railway station, the number of the expansion control boxes can be increased at will; when a small railway station is met, the number of the expansion control boxes is reduced.

The expansion control box is detachably provided with a signal machine board card, a switch machine board card and a track circuit board card, and similarly, the number of the signal machine board card, the switch machine board card and the track circuit board card on the expansion control box can be one or more.
Because the integrated circuit board is demountable installation on main control box or extension control box, so can install a signal machine integrated circuit board, a plurality of goat integrated circuit board, a plurality of track circuit integrated circuit board on the main control box for example, or other quantity, but main control box is last to have and only one main control unit integrated circuit board. Similarly, the board cards installed on the expansion control box can also be installed according to the number of the required board cards in the actual application scene.
However, the signal machine board card, the switch machine board card and the track circuit board card on the main control box or the expansion control box are in card connection communication with the main controller board card on the main control box. The main control box and the expansion control box are both provided with a serial bus, and after the board cards are installed on the control box, signals of the board cards are transmitted to the main controller board cards from the serial bus.

If the real railway station needs to simulate 19 groups of signal machines, 3 signal machine board cards arranged on the main control box are used; or 1 signal machine board card arranged on the main control box and 2 signal machine board cards arranged on an expansion control box are added; or 1 signal machine board card installed on the main control box, 1 signal machine board card installed on one expansion control box, and 1 signal machine board card installed on the next expansion control box. Therefore, all simulation of 8 groups of signal lamps on 2 signal machine board cards is realized, and simulation of 3 groups of signal lamps on the 3 rd signal machine board card is realized.
It is thus clear that, according to the quantity of the equipment that needs the simulation at real railway station, confirm the data of required semaphore integrated circuit board, that is to say that every semaphore integrated circuit board can simulate 8 real semaphore equipment, when the real semaphore equipment more than 8 of needs simulation, then increase the semaphore integrated circuit board can, the semaphore integrated circuit board that increases can be installed on the main controller case, also can install on the expansion control case.

Then the host computer can assign simulation instruction to the main control box according to outdoor equipment signal plane diagram, and the simulation instruction that the host computer assigned includes the instruction of simulation true semaphore, the instruction of simulation true goat, the instruction of simulation true track circuit.
Step S2: the main control unit integrated circuit board of main control box is according to the analog command that the host computer was assigned, with analog command signal transmission to the integrated circuit board that corresponds to receive the analog signal of integrated circuit board feedback, upload the analog signal of integrated circuit board feedback to host computer and indoor interlocking machine and show.
When the simulation instruction that the host computer was assigned is the instruction of the true semaphore of simulation, the main control unit integrated circuit board of main control box will simulate the instruction of the true semaphore and send the semaphore integrated circuit board that corresponds to, for example will simulate 7 true semaphores, then send the simulation instruction to a semaphore integrated circuit board, select 7 groups of signal lamps to be used for simulating the filament of true semaphore and bright, the state of going out in this semaphore integrated circuit board.
Then the analog signal after signal machine integrated circuit board will simulate real signal machine's filament bright, the state of going out sends to the main control unit integrated circuit board, and the simulation instruction that for example signal lamp 0 received is the bright state of simulation filament, and signal lamp 0 circular telegram so converts into bright state to the analog signal that signal lamp 0 was bright state is sent to the main control unit integrated circuit board with the signal machine integrated circuit board at signal lamp 0 place.
The main controller board card uploads the simulation signal of the signal lamp 0 in the bright state to the upper computer and the indoor interlocking machine to be displayed, the signal lamp 0 displayed on the upper computer is supposed to be in the bright state under the normal working state, and the state of the signal lamp 0 displayed on the indoor interlocking machine is also supposed to be in the bright state, so that the simulation of the signal lamp 0 is completed. It can be seen that in this example, the signal light 0 is used to simulate a real signal.
When the simulation instruction that host computer was given is the instruction of the true goat of simulation, the main control unit integrated circuit board of main control box will simulate the instruction of true goat and send the instruction of the true goat to the goat integrated circuit board that corresponds, for example will simulate 6 true goat, then send the simulation instruction to two goat integrated circuit boards (one of them goat integrated circuit board simulation 4 true goat, 2 true goat of another goat integrated circuit board simulation), these two goat integrated circuit boards are used for simulating location, counterpoint, crowded switch state of true goat.
And then the switch board card sends the analog signals after simulating the positioning, the reverse position and the switch squeezing state of the real switch to the main controller board card, for example, if the analog instruction received by a certain group of analog switches is in the analog positioning state (or the reverse position state), the group of analog switches is converted into the positioning state (or the reverse position state), and the switch board card where the group of analog switches is located sends the analog signals simulating the positioning state (or the reverse position state) of the switch to the main controller board card.
The main controller board card uploads the simulation signal of the simulation switch machine in the positioning state (or the reverse state) to the upper computer and the indoor interlocking machine for displaying, and in the normal working state, the simulation switch machine displayed on the upper computer should be in the positioning state (or the reverse state), and the simulation switch machine displayed on the indoor interlocking machine should also be in the positioning state (or the reverse state).
However, for example, if the simulation instruction received by a certain group of simulation switches is a simulation switch-crowd state (off-state), a person is required to press a switch button on the switch board where the group of simulation switches is located, and the switch button is specially used for simulating the switch-crowd state of a real switch. Similarly, the switch board card sends an analog signal for simulating that the switch is in a switch squeezing state to the main controller board card.
When the simulation instruction that the host computer was issued is the instruction of simulation true track circuit, the main control unit integrated circuit board of main control box will simulate the instruction of true track circuit and send the instruction of simulation true track circuit to the track circuit integrated circuit board that corresponds, for example will simulate 20 true track circuits, then send the simulation instruction to three track circuit integrated circuit boards (wherein two track circuit integrated circuit boards all simulate 8 true track circuits, and the third track circuit integrated circuit board simulates 4 true track circuits), and these three track circuit integrated circuit boards are used for simulating the district section of true track circuit and occupy, the district section state of coming out of order.
Then, the track circuit board card sends the analog signal after simulating the section occupation and section clearing of the real track circuit to the main controller board card, for example, if the analog command received by a certain group of analog track circuits is the analog section occupation state (or section clearing state), the group of analog track circuits is converted into the section occupation state (or section clearing state), and the track circuit board card where the group of analog track circuits is located sends the analog signal simulating the track circuit in the section occupation state (or section clearing state) to the main controller board card.
And the main controller board card uploads the analog signal of the analog track circuit in an occupied state (or a clear state) to the upper computer and the indoor interlocking machine for displaying, and in a normal working state, the analog track circuit displayed on the upper computer is in a zone occupied state (or a zone clear state), and the analog switch machine displayed on the indoor interlocking machine is also in a zone occupied state (or a zone clear state).
Step S3: and if the analog signal displayed by the interlocking machine is inconsistent with the analog signal displayed by the upper computer, finding out a simulation fault point so as to debug the interlocking machine.
If the state of the analog signal displayed on the indoor interlocking machine is inconsistent with the state of the analog signal displayed on the upper computer, the problem that the corresponding logic circuit or wiring of the indoor interlocking machine is in construction is shown, and then personnel find out a simulation fault point according to the inconsistent analog signal, so that the interlocking machine is debugged. In the present solution, no limitation is made on how to find out the simulation fault point.
