Description

Technical Field

[0001] This utility model belongs to the technical field of railway signaling systems, and more specifically, relates to a 6502 electrical centralized voice alarm system. Background Technology

[0002] The 6502 electrical centralized interlocking system is the most widely used relay-type electrical centralized interlocking system in my country. It centrally controls and monitors turnouts, routes, and signals electrically, and interlocks them. The 6502 control circuit is highly standardized and logically sound. Even upgraded computer interlocking systems still utilize the circuit structure and principles of the 6502 electrical centralized interlocking system, making it fundamental technical knowledge for signaling professionals. Many railways still use the 6502 electrical centralized interlocking system, such as the Chengdu-Kunming Railway and the Zixu Railway. Many railway bureaus' training bases are also equipped with the 6502 electrical centralized interlocking system as essential practical training knowledge for electrical engineers.

[0003] The 6502 electrical centralized control system primarily uses relay combinations to achieve interlocking control, ensuring train operation safety. The alarm system is triggered by changes in the contact states of various relays, which in turn activates the electric bell to issue an alarm.

[0004] A typical station usually has about 10 alarm messages, including fault alarms such as turnout alarm, upper and lower filament breakage alarm, circuit breaker alarm, and frequency shift alarm. In addition, the electric bell sound can trigger status alarms such as blockage information, train approach, level crossing approach, and power switching.

[0005] However, in existing technology, all alarms emit the same sound via electric bells. When multiple alarms occur simultaneously, technicians cannot quickly distinguish the fault type, leading to prolonged fault handling time and low emergency response efficiency. This problem is particularly prominent on railway lines such as the Chengdu-Kunming Railway and the Zixu Railway, which still use the 6502 system, affecting the training of electrical personnel and actual operation and maintenance. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a 6502 electrical centralized voice alarm system that can accurately identify fault types through voice alarms and improve fault handling efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A 6502 electrical centralized voice alarm system includes a 6502 electrical centralized control console. The 6502 electrical centralized control console is equipped with multiple alarm relays based on different fault types, and multiple alarm signal output terminals are provided corresponding to the multiple alarm relays. The system is characterized by further comprising:

[0009] The voice control module has a variety of pre-stored voice alarm data based on different fault types, and each type of voice alarm data has a corresponding control signal input port;

[0010] The voice amplifier module and speaker are electrically connected to the output terminal of the voice control module;

[0011] A DC power supply module is used to convert external input power into DC operating voltage to power the voice control module, the voice power amplifier module and the speaker;

[0012] The control relay group includes multiple control relays that are connected one-to-one with the input ports of the voice control module. The control relays are connected to an external power supply. The normally open contact output terminal of the control relay is electrically connected to the control signal input port of the voice control module. The coil input terminal of the control relay is electrically connected to the alarm signal output terminal of the 6502 electrical centralized control console.

[0013] As a further preferred embodiment of this technical solution, the voice alarm data includes power-on prompt audio, upper filament alarm audio, lower filament alarm audio, fuse alarm audio, turnout alarm audio, speed-up turnout fault alarm audio, station frequency shift alarm audio, section frequency shift alarm audio, upward three-proximity alarm audio, and downward three-proximity alarm audio.

[0014] As a further preferred embodiment of this technical solution, the control relay is a DC 24V relay.

[0015] As a further preferred embodiment of this technical solution, the energization of the control relay is triggered by a change in the state of the alarm relay in the 6502 electrical centralized control console, and the control logic is as follows:

[0016] The alarm relay is energized when a fault occurs, its normally open contact closes, and it outputs a high-level signal.

[0017] The high-level signal is input to the corresponding control relay through the alarm signal output terminal, and the power supply circuit of the control relay is turned on, so that the coil of the control relay is energized.

[0018] After the coil of the control relay is energized, its normally open contact closes, thereby connecting the voice control module to form a voice control circuit, providing a trigger signal for subsequent alarm voice broadcasts.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention utilizes pre-stored customized voice alarm data based on different fault types. When a specific alarm relay in the 6502 electrical centralized control console is energized, it triggers the corresponding control relay, thereby activating the voice control module to broadcast the corresponding alarm voice. This system replaces the original electric bell-triggered alarm structure with a control relay group, eliminating the need to change the original circuit interlocking, ensuring safety and reliability. Compared to traditional single electric bell alarms that require technicians to verify the control console indicator lights on-site, the direct voice broadcast of fault types in this system effectively improves fault identification efficiency. Furthermore, the semantic-level alarm method enables technicians to instantly identify core issues in scenarios with multiple concurrent faults, significantly improving emergency response efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figures 1 to 2 The illustrated 6502 electrical centralized voice alarm system includes a 6502 electrical centralized control console. The 6502 electrical centralized control console is equipped with multiple alarm relays based on different fault types, and multiple alarm signal output terminals are provided corresponding to the multiple alarm relays. In this embodiment, using the 6502 electrical centralized control console to receive fault detection data to control the excitation of the corresponding alarm relays is a conventional technical means in the art. The traditional fault alarm method is to connect the alarm relay to the console bell, and the alarm is prompted by the sound of the bell.

[0027] In this embodiment, based on different fault types, the alarm relays include: power-on reminder relay, upper filament alarm relay (SDSJ), lower filament alarm relay (XDSJ), fuse alarm relay (RSBJ), derailment alarm relay (JCJ-derailment relay, JCAJ-derailment button relay), speed-up turnout fault alarm relay (TSGJ), station frequency shift alarm relay (ZYBJ), interval frequency shift alarm relay (QYBJ), upward three-proximity alarm relay (S3JGJ), and downward three-proximity alarm relay (X3JGJ).

[0028] The core of this embodiment lies in:

[0029] It also includes a voice control module, which pre-stores various voice alarm data based on different fault types. In this embodiment, according to the alarm relays of different fault types equipped on the 6502 electrical centralized control console, the voice alarm data in the voice control module includes: power-on prompt audio, upper filament alarm audio, lower filament alarm audio, fuse alarm audio, turnout alarm audio, speed-up turnout fault alarm audio, station frequency shift alarm audio, section frequency shift alarm audio, upward three-proximity alarm audio, and downward three-proximity alarm audio; correspondingly, ten control signal input ports are provided for the above ten types of voice alarm data;

[0030] Since a large number of control signal input ports are required, the voice control module in this embodiment is composed of two YX6100 voice control module units, namely voice control module 1 and voice control module 2. Each YX6100 voice control module unit includes 6 control signal input ports, namely P1, P2, P3, P4, P5 and P6.

[0031] It also includes a voice power amplifier module and a speaker that are electrically connected to the output of the voice control module. In this embodiment, the voice power amplifier module adopts a TDA2050 voice power amplifier module unit. The function of the voice power amplifier module is to convert the low-power electrical signal data output by the voice control module into high-power audio output and drive the speaker to achieve a clear and distinguishable voice alarm. This module plays the role of "signal amplifier" in this system to ensure that the alarm voice is effectively propagated in the noisy railway control room environment.

[0032] It also includes a DC power supply module for converting external input power into DC operating voltage to power the voice control module, the voice amplifier module and the speaker. In this embodiment, a 12V DC power supply module is used.

[0033] It also includes a control relay group, which corresponds to a plurality of control relays that are connected one-to-one with the input ports of the voice control module. In this embodiment, the control relay is a DC 24V relay. The control relay is connected to a 24V external power supply. The normally open contact output terminal of the control relay is electrically connected to the control signal input port of the voice control module. The coil input terminal of the control relay is electrically connected to the alarm signal output terminal of the 6502 electrical centralized control console.

[0034] In this embodiment, the control relays corresponding to the alarm relays and voice alarm data of the different fault types mentioned above include: power-on prompt control relay (J1), upper filament alarm control relay (J2), lower filament alarm control relay (J3), fuse alarm control relay (J4), turnout derailment alarm control relay (J5), speed-up turnout fault alarm control relay (J6), station frequency shift alarm control relay (J7), section frequency shift alarm control relay (J8), upward three-proximity alarm control relay (J9), and downward three-proximity alarm control relay (J10).

[0035] Correspondingly, the coil input terminals of the multiple control relays are electrically connected to the multiple alarm relays one by one according to different fault types, and the normally open contact output terminals of the multiple control relays are electrically connected to the multiple control signal input ports one by one. The specific correspondence is as follows:

[0036] Power-on prompt relay - Power-on prompt control relay (J1) - P1 port of voice control module 1;

[0037] Upper filament alarm relay (SDSJ) - Upper filament alarm control relay (J2) - P2 port of voice control module 1;

[0038] Lower filament alarm relay (XDSJ) - Lower filament alarm control relay (J3) - P3 port of voice control module 1;

[0039] Fuse alarm relay (RSBJ) - Fuse alarm control relay (J4) - P4 port of voice control module 1;

[0040] The derailment alarm relay (JCJ-derailment relay, JCAJ-derailment button relay) - derailment alarm control relay (J5) - P5 port of voice control module 1;

[0041] Speed-up turnout fault alarm relay (TSGJ) - Speed-up turnout fault alarm control relay (J6) - P6 port of voice control module 1;

[0042] Station frequency shift alarm relay (ZYBJ) - Station frequency shift alarm control relay (J7) - P1 port of voice control module 2;

[0043] Interval frequency shift alarm relay (QYBJ) - Interval frequency shift alarm control relay (J8) - P2 port of voice control module 2;

[0044] Upward proximity alarm relay (S3JGJ) - Upward proximity alarm control relay (J9) - P3 port of voice control module 2;

[0045] Downward proximity alarm relay (X3JGJ) - Downward proximity alarm control relay (J10) - P4 port of voice control module 2.

[0046] Example 2

[0047] Based on the technical solution disclosed in Embodiment 1, this embodiment takes an in-station frequency shift alarm as an example to further illustrate the typical fault alarm triggering process of this application:

[0048] Step 1: Signal Detection

[0049] When the frequency shifting equipment in the station fails, the frequency shifting alarm relay (ZYBJ) in the 6502 electrical centralized control console is energized, that is, its coil is energized, the normally open contact closes, and a high-level signal is output.

[0050] Step 2: Voice device triggered

[0051] The station frequency shift alarm relay (ZYBJ) contacts close → connects the 24V external power supply circuit of the station frequency shift alarm control relay (J7) → the coil of the station frequency shift alarm control relay (J7) is energized → the normally open contact of the station frequency shift alarm control relay (J7) closes → connects the P6 port of the voice control module 1.

[0052] Step 3: Voice broadcast

[0053] The voice amplifier module receives the electrical signal output from the P6 port of the voice control module 1, calls up the audio data containing "station frequency shift alarm", and plays the alarm voice through the speaker.

[0054] Step 4: Alarm terminated

[0055] After the fault is repaired, the station frequency shift alarm relay (ZYBJ) loses its magnetization → the coil of the station frequency shift alarm control relay (J7) is de-energized and loses its magnetization → the normally open contact of the station frequency shift alarm control relay (J7) opens → the output level signal of the P6 port of the voice control module 1 returns to zero → the alarm voice playback stops immediately.

[0056] Example 3

[0057] Based on the technical solution disclosed in Embodiment 1, this embodiment takes multiple fault alarms as an example, such as the simultaneous occurrence of an upper filament breakage alarm and a fuse alarm, to further illustrate the fault alarm triggering process of this application:

[0058] Step 1: Parallel signal triggering

[0059] Excitation of the filament alarm relay (SDSJ) → energization of the coil of the filament alarm control relay (J2) → connection of the P2 port of the voice control module 1 → broadcast of the voice message "filament alarm".

[0060] The fuse alarm relay (RSBJ) is energized → the coil of the fuse alarm control relay (J4) is energized → the P4 port of the voice control module 1 is connected → the voice message "Fuse alarm" is broadcast.

[0061] Step 2: Voice Logic Priority

[0062] The system cycles through the port numbers of the voice control module 1 (P2→P4→P2→P4…) with a 1-second interval; technicians can clearly identify the two types of faults.

[0063] Step 3: Fault Elimination Verification

[0064] After repairing the filament fault, the filament alarm relay (SDSJ) loses its magnetism → the coil of the filament alarm control relay (J2) is de-energized and loses its magnetism → the output level signal of the P2 port of the voice control module 1 returns to zero → only the "fuse alarm" voice is played in a loop.

[0065] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
