Description
Technical fields:
[0001] This utility model relates to the field of railway electrical engineering drill technology, and in particular to a ZPW2000R drill simulation platform for electrical engineering workshops. Background technology:
[0002] Railway electrical engineering training bases are all located in the electrical engineering section, while railway electrical engineering field work areas are distributed in various areas along the railway line. This causes great inconvenience to the on-site employees' practical training and drills, and makes it difficult to improve the employees' technical and professional skills.
[0003] To solve this problem, a convenient and cost-effective training unit needs to be developed. Currently, the technical circuits used include the station entrance signal control circuit diagram and the ZPW2000R automatic block signaling circuit diagram. To train on these two schematics, a simple route control circuit that basically conforms to actual field conditions must be designed, combining the two practical technical circuits to simulate normal station entry, section signaling, and normal code transmission. Simultaneously, for ease of training, computer software is used to control input / output relay modules, enabling the demonstration and recovery of equipment malfunctions.
[0004] Existing technologies, which all require computer interlocking equipment and power supply panels, suffer from high costs and large space requirements. Furthermore, on-site electrical work areas are generally characterized by small spaces and dispersed locations, making it impossible to equip each work area with complete sets of equipment for employees to conduct practical training. Summary of the Invention:

This invention provides a ZPW2000R on-site training simulation platform for electrical engineering workshops, characterized by comprising a ZPW2000R block cabinet, a through signal, an entry signal, and a training operation control console connected in series via circuitry.
[0006] The entrance signal is equipped with a lighting circuit relay assembly, an interlocking relay assembly, a node relay assembly, and a track relay assembly.

[0018] The training operation control console is equipped with a track light strip group to display the signal open status.

[0050] like Figure 1 As shown, this utility model provides a ZPW2000R practical training simulation platform for electrical workshops, characterized in that it includes a ZPW2000R section block cabinet 1, a section through signal 2, an entry signal 3, and a practical operation control console 4, which are connected in series by circuits.
[0051] The entrance signal 3 is equipped with a lighting circuit relay assembly 5, an inter-control relay assembly 6, a node relay assembly 7, and a track relay assembly 8. The inter-control relay assembly 6 is used to realize the interlocking relationship between the inter-control relays in the lighting circuit relay assembly 5 and to control the raising and lowering of these relays. The node relay assembly 7 is used to increase the number of nodes in the entrance signal 3. The track relay assembly 8 is used to restore the outdoor lighting circuit of the entrance signal 3.
[0052] The station entry signal 3 is also equipped with a station entry signal repeater light assembly 9, which is electrically connected to the lighting circuit relay assembly 5. It is used to distinguish between the normal positioning status of the display device, the open side line receiving status, the open main line receiving status, the open main line passing status, and the open guidance receiving status.
[0053] The station entry signal 3 is also equipped with a filament relay DJ.
[0054] The training operation console 4 is equipped with a button combination 10 for connecting and disconnecting contacts.
[0055] The section signal 2 is also equipped with a 16-channel serial port controlled electromagnetic relay module 11, and the station entrance signal 3 is also equipped with an 8-channel serial port controlled electromagnetic relay module 12. The 16-channel serial port controlled electromagnetic relay module 11 and the 8-channel serial port controlled electromagnetic relay module 12 are connected in series and then connected to an RS485 communication acquisition module 13. The RS485 communication acquisition module 13 is in turn connected to a computer host 14 to control the raising and lowering of the electromagnetic relays, thereby simulating a broken or mixed wire fault.
[0056] The ZPW2000R section block cabinet 1 is externally connected to a 48V DC regulated power supply 15, and the station entry signal 3 is externally connected to a 24V DC regulated power supply 16. Both the 48V DC regulated power supply 15 and the 24V DC regulated power supply 16 are externally connected to 220V AC mains power.
[0057] The lighting circuit relay assembly 5 includes: train signal relay LXJ, mainline signal relay ZXJ, through signal relay TXJ, green-yellow signal relay LUXJ, and guide signal relay YXJ.
[0058] The inter-control relay assembly 6 includes: route check relay JLJ, lockout relay SJ, indication control relay BKJ, guide button relay YAJ, and side line relay CXJ.
[0059] The node relay assembly 7 includes: a guide signal repeater relay YXJF, a main line repeater relay ZXJF, and a side line repeater relay CXJF.
[0060] The track relay assembly 8 includes: a track relay DGJ for the turnout section within the station, a track relay IGJ for the first track, a track relay IIGJ for the second track, a departure track relay 1LQGJ, and a departure track relay 2LQGJ.
[0061] The station entrance signal repeater light assembly 9 includes five station entrance signal repeater light units: 1U lighting unit 1U, L lighting unit L, H lighting unit H, 2U lighting unit 2U, and B lighting unit B. Correspondingly, 1U display light 1U′, L display light L′, H display light H′, 2U display light 2U′, and B display light B′ are provided.
[0062] The section is equipped with a U-lighting unit U, an L-lighting unit L, and an H-lighting unit H on the signal machine, and correspondingly, a U-indicator U′, an L-indicator L′, and an H-indicator H′ are provided.
[0063] The button combination 10 includes: the starting train button LA, the terminal up track I train button SIA, the terminal up track II train button SIIA, the pass button TA, the guide button YDA, the power outage unlock button TDJSA, the turnout indication control button DBKA, and the cancel button QA. All buttons are self-resetting buttons, which are activated when pressed and deactivated when released.
[0064] The training operation control console 4 is equipped with a track light strip group to display the signal open status. The track light strip group includes: track light strip DG for the turnout section in the station, track light strip IG for track I, and track light strip IIG for track II. The above light strips are red and white light strips. It also includes a departure track light strip 1LQG and a departure track light strip 2LQG. The above light strips are red light strips. The training operation control console is also equipped with main line and side line indicator lights on track IIG and track IG to represent the turnout open position.
[0065] Five open-circuit track circuits were also set up using a rail model, along with lighting units and lamp holders to recreate the outdoor lighting circuit of the station entry signal.
[0066] Example 1:
[0067] like Figure 2 The diagram shown is the circuit diagram of the positive line signal relay ZXJ.
[0068] The SIIA button for the upstream train on track II represents the track II terminal button and also the fixed-operation turnout. The third set of contacts of the locking relay SJ is connected in this circuit to establish an interlocking relationship where the turnout cannot be operated when the route is locked. The second set of contacts of the control relay BKJ is used to check whether the turnout on the route is engaged and locked in the specified position when an open signal is received. The contacts of the second track relay IIGJ and the filament relay DJ are used to check whether the section on the route is in an idle state when an open signal is received. The third set of contacts of the filament relay DJ also establishes an interlocking relationship where the turnout cannot be operated when a car occupies the section. The third set of contacts of the siding relay CXJ is used to check whether the turnout position is correct when an open signal is received. When the route is locked, the locking relay SJ drops, and the fourth set of contacts of the locking relay SJ activates the self-closing circuit of the main line relay ZXJ. At this time, the main line relay ZXJ no longer checks the above interlocking relationships, but only checks whether the turnout position is correct. At this point, the corresponding interlocking relationship is checked through the self-closing circuit of the train signal relay LXJ. When the guide signal is released, the check for the vacancy of the section on the route is no longer performed. The second group of guide button relays YAJ activates the main line relay ZXJ, while the seventh group of guide signal relays YXJ is activated to prevent the guide button YDA from being pressed for too short a time, thus preventing the locking relay SJ from deactivating and causing the route to be incorrectly arranged.
[0069] Example 2:
[0070] like Figure 3 The diagram shown is the circuit diagram of the inlet inspection relay JLJ.
[0071] The route inspection relay JLJ circuit is used to check the consistency between the operator's operating method and intention. The operating intention must be consistent with the turnout's open position. When the SIIA button for the train on track II in the terminal is pressed, the turnout position must be in the correct position; when the SIA button for the train on track I in the terminal is pressed, the turnout position must be in the reverse position. Because the button is a self-resetting button, the route inspection relay JLJ circuit is designed with two self-closing circuits to ensure the activation of the route inspection relay JLJ. Before the route is locked, the activation of the train signal relay LXJ or the guide signal relay YXJ and the deactivation of the siding relay CXJ or the mainline signal relay ZXJ ensure the self-closing of the route inspection relay JLJ. After the route is locked, the above conditions are no longer checked; instead, the self-closing circuit of the train signal relay LXJ or the guide signal relay YXJ is used for checking.
[0072] Example 3:
[0073] like Figure 4 The diagram shown is the circuit diagram of the train signal relay LXJ.
[0074] In the LXJ train signal relay ignition circuit, the first group of the guide signal repeater relay YXJF is connected to check whether the opposing signal is open. The main line repeater relay ZXJF and the siding repeater relay CXJF are used to check whether the turnout position is correctly interlocked. After the route check relay JLJ closes automatically, it no longer checks the section status on the route. Therefore, the contacts of the first track relay IGJ, the second track relay IIGJ, and the filament relay DJ are connected to the circuit to check whether the route is in an idle state. The first group of the filament relay DJ is used to check the integrity of the filament. When the red light filament is broken, the signal cannot be opened.
[0075] Example 4:
[0076] like Figure 5 The diagram shown is the circuit diagram of the side-line relay CXJ.
[0077] The terminal's up-track I train button SIA also represents a fixed-operation turnout. In this circuit, the first set of latching relays SJ is connected to establish an interlocking relationship where the turnout cannot be operated when the route is locked. The first set of control relays BKJ is used to ensure that when an open signal is received, the turnout position on the route is indicated and locked in the specified position. The contacts of track relay IGJ and filament relay DJ are used to check whether the section of the route is in an idle state when an open signal is received. Simultaneously, the third set of filament relays DJ also establishes an interlocking relationship where the turnout cannot be operated when a car occupies the section. The first set of mainline relays ZXJ is used to check whether the turnout position is correct when an open signal is received.
[0078] Example 5:
[0079] like Figure 6 The diagram shown is the circuit diagram of the green / yellow signal relay LUXJ and the signal relay TXJ.
[0080] The contact is activated by pressing button TA, and deactivated by pressing button SIIA (Train 2 Upward) on the terminal. To prevent the green-yellow signal relay LUXJ from erroneously activating when button SIIA is pressed during mainline stop signal processing, thus incorrectly opening a through signal, the LUXJ circuit includes the sixth group of guide signal relays YXJ to check if a hostile signal is open, the first group of departure track relays 1LQGJ to control whether a through signal or green-yellow signal is open when a car occupies a departure section, and the fourth group of siding relays CXJ to check if the turnout is in the designated position. The LUXJ self-closing circuit no longer checks for hostile signals; instead, the check is performed through the circuit of the LXJ relay.
[0081] The interlocking relationship is checked by connecting the green and yellow signal relays LUXJ to the signal relay TXJ circuit. The first group of the second departure track relay 2LQGJ is used to ensure that the passage signal cannot be opened when a car occupies the second departure track.
[0082] Example 6:
[0083] like Figure 7 The diagram shown is the circuit diagram of the guide signal relay YXJ.
[0084] The YXJ signal relay first connects to the fourth group of train signal relays LXJ in the circuit to check whether the opposing signal is open. The ZXJF main line repeater relay and the CXJF siding repeater relay are used to check whether the turnout position is correctly interlocked. After the route check relay JLJ closes automatically, it no longer checks the section status on the route. The first group of filament relays DJ is used to check the integrity of the filament. When the red light filament is broken, the signal cannot be opened.
[0085] Example 7:
[0086] like Figure 8 The diagram shown is the circuit diagram of the latching relay SJ.
[0087] To achieve route locking functionality consistent with the on-site interlocking system, a locking relay SJ was designed, and a power-off button TDA was added to enable power-on locking. The self-closing circuit of the locking relay SJ is connected to the contacts of the train signal relay LXJ and the guide signal relay YXJ to implement route locking after the signal is released.
[0088] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
