AI Technical Summary
Traditional interlocking systems suffer from interlocking errors and low debugging efficiency in subway signal commissioning. In particular, the simultaneous testing of relay front and rear contact acquisition and coil drive testing leads to low manual interlocking efficiency and a high risk of poor connection.
The stepless relay simulation verification method is adopted. By configuring the stepless relay base, simulated contacts and coil, the relay state is simulated by a passive push-button switch, and the success is driven by the indicator light, so as to realize the automated testing of the relay front and rear nodes.
It improves the efficiency and accuracy of manual simulation of interlocking, and makes the driving test of relay coils of interlocking equipment more intuitive, greatly improving the efficiency of debugging and fault handling.

Abstract
Description
Technical Field
[0001] This invention relates to the field of electrical technology, and in particular to a method for simulating and verifying interlocking acquisition and driving using a stepless relay for subway applications. Background Technology
[0002] The commissioning of the metro signal interlocking subsystem is divided into static commissioning and consistency commissioning. Static commissioning refers to the verification test, mainly data code communication, carried out before the functional test of the interlocking subsystem. The data code communication test is divided into the acquisition test of the interlocking machine on the front and rear contacts of the relay and the driving test of the interlocking machine on the relay coil. The interlocking drive and acquisition relays are usually railway signal stepless relays.
[0003] In the static commissioning of interlocking of newly added equipment on existing subway lines, manual sealing of the front and rear contacts of the relay base plate is usually used to simulate the relay's lifting and lowering state, thereby completing the acquisition and testing of the interlocking equipment's front and rear nodes of the relay. The interlocking equipment's drive test of the relay coil is usually completed before or after the acquisition and testing.
[0004] Traditional interlocking systems have the following static problems: During the manual sealing of relay base plate contacts using sealing cables for the acquisition and testing of relay front and rear contacts, sealing errors frequently occur. The sealing process can also easily lead to poor connections between external cables and base plate terminals. Furthermore, in static interlocking debugging, the code position acquisition and testing of the same relay and the relay coil drive code position testing cannot be performed simultaneously; one must be completed before testing the other, resulting in low debugging efficiency. Summary of the Invention
[0005] The purpose of this invention is to provide a method for simulating and verifying interlocking acquisition and driving using stepless relays in subway systems, so as to solve the problems of frequent interlocking errors and low debugging efficiency in traditional interlocking systems.
[0006] This invention provides a method for simulating and verifying interlocking acquisition and driving using a stepless relay for subway use, comprising: configuring a stepless relay base, a stepless relay simulated contact, and a stepless relay simulated coil;
[0007] The base of the infinite relay includes a first simulated coil contact, a second simulated coil contact, a simulated first group of infinite relay contacts, a simulated second group of infinite relay contacts, a simulated third group of infinite relay contacts, a simulated fourth group of infinite relay contacts, a simulated fifth group of infinite relay contacts, a simulated sixth group of infinite relay contacts, a simulated seventh group of infinite relay contacts, and a simulated eighth group of infinite relay contacts; each simulated infinite relay contact group includes a front contact, a middle contact, and a rear contact;
[0008] The simulated contacts of the infinitely variable relay are connected to the front, middle and rear contacts of the infinitely variable relay base by a first passive push button switch, and the opening and closing state of the first passive switch simulates the lifting and lowering state of the infinitely variable relay.
[0009] The infinitely variable relay analog coil includes an indicator light, a switching diode, and a second passive push button switch. When testing the first analog coil contact of the infinitely variable relay base, pressing the second passive push button switch corresponding to the first analog coil contact causes the interlocking device to issue a drive command for the first analog coil contact. The switching diode identifies the direction of the current; the indicator light will only illuminate if the direction of the current issued by the interlocking device is correct. The illumination of the indicator light indicates successful drive. The drive principle of the second analog coil contact is the same as that of the first analog coil contact.
[0010] Furthermore, the indicator light is a DC indicator light.
[0011] Furthermore, the indicator light is a 24V indicator light.
[0012] Furthermore, the analog stepless relay for subway signals also includes: a housing, which is made of plastic or metal.
[0013] Furthermore, the dimensions of the device housing are 165 mm × 49 mm × 163 mm.
[0014] This invention offers the following advantages: The method for simulating and verifying interlocking data acquisition and driving using a stepless relay in subway systems utilizes a passive switch to simulate the relay's activation and deactivation states, thereby completing the data acquisition and testing of the relay's upstream and downstream nodes by the interlocking equipment. This significantly improves the efficiency and accuracy of manual simulation of interlocking operations. The interlocking equipment's driving test of the relay coil is visually indicated by indicator lights, making it immediately clear whether the two sets of coils of the stepless relay have been successfully driven. In railway signal interlocking relay interface circuits, the activation state of the stepless relay can be manually simulated, greatly improving the efficiency of single-circuit debugging and fault handling of the interlocking relay interface.

[0016] Figure 1 The structural diagram of the method for simulating and verifying interlocking acquisition and driving using a stepless relay for subways provided by the present invention is shown. Detailed Implementation
[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be pointed out that the following detailed description is illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0018] Please see Figure 1 The present invention provides a method for simulating and verifying interlocking acquisition and driving of a stepless relay for subway use, comprising: configuring a stepless relay base, a stepless relay simulation contact, a stepless relay simulation coil and a device housing.
[0019] The base of the infinite relay is consistent with the existing base of infinite relays used in railways, and has the following characteristics: Figure 1 The four coil contacts shown are “1, 2, 3, 4”. “1, 2” is a simulated coil contact, namely the first simulated coil contact; “3, 4” is a simulated coil contact, namely the second simulated coil contact.
[0020] The base of the infinite relay also has simulated the first group of infinite relay contacts, the second group of infinite relay contacts, the third group of infinite relay contacts, the fourth group of infinite relay contacts, the fifth group of infinite relay contacts, the sixth group of infinite relay contacts, the seventh group of infinite relay contacts, and the eighth group of infinite relay contacts; each simulated infinite relay contact group includes a front contact, a middle contact, and a rear contact.
[0021] like Figure 1 As shown, "11, 12, 13" represent the simulated first group of non-polarized relay contacts. "11" is the middle contact of the simulated first group of non-polarized relay contacts, "12" is the front contact (the pull-up contact), and "13" is the rear contact (the drop-down contact). Similarly, the non-polarized relay base has contacts "11-83", totaling eight groups of simulated non-polarized relay contacts.
[0022] The simulated contacts of the stepless relay are connected to the front, middle and rear contacts of the base of the stepless relay by a first passive push button switch. The opening and closing state of the first passive switch simulates the lifting and lowering state of the stepless relay.
[0023] The infinitely variable relay analog coil includes an indicator light, a switching diode, and a second passive push button switch. When testing the first analog coil contact of the infinitely variable relay base, pressing the second passive push button switch corresponding to the first analog coil contact will trigger the interlocking device to send a drive command to the first analog coil contact. The switching diode identifies the direction of the current; the indicator light will only illuminate if the current direction from the interlocking device is correct. The illumination of the indicator light indicates successful drive. The drive principle of the second analog coil contact is the same as that of the first analog coil contact.
[0024] In this embodiment, the indicator light is a DC 24V indicator light.
[0025] In this embodiment, the device housing is made of plastic or metal. The dimensions of the device housing are 165 mm × 49 mm × 163 mm.
[0026] As can be seen from the above embodiments, the method for simulating and verifying interlocking acquisition and driving using a stepless relay in subways according to the present invention achieves the picking and dropping state of the stepless relay by pressing a passive switch to simulate the contact, thereby completing the acquisition and testing of the relay's front and rear nodes by the interlocking equipment. This greatly improves the efficiency and accuracy of manual simulation of interlocking. The driving test of the relay coil by the interlocking equipment is visually reflected by indicator lights, making it clear whether the two sets of coils of the stepless relay have been successfully driven. In the railway signal interlocking relay interface circuit, the picking state of the stepless relay can be manually simulated, greatly improving the efficiency of single-circuit debugging and fault handling of the interlocking relay interface.
