Description

Technical Field

[0001] This invention relates to the field of rail transit communication and broadcast control technology, and in particular to an integrated passenger alarm device. Background Technology

[0002] Currently, passenger broadcasting systems and passenger emergency alarms in rail transit vehicles typically employ a separate architecture: noise detection devices are installed separately inside the passenger compartment to collect ambient noise and adjust broadcast volume; while the passenger emergency alarms function solely as a voice intercom between passengers and the driver or control center. This design suffers from drawbacks in terms of structural deployment, including equipment redundancy, complex wiring, and difficult maintenance. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to propose an integrated passenger alarm that combines a noise detector with a passenger alarm, thereby improving the integration level of the passenger alarm device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides an integrated passenger alarm device. The integrated passenger alarm includes: The noise detection module is used to collect ambient noise signals in the passenger room in real time during non-emergency intercom use and generate corresponding noise level parameters. The passenger emergency alarm module includes an alarm triggering unit and a microphone unit. The alarm triggering unit is used to respond to the passenger's alarm operation. The microphone unit is used to establish a two-way voice communication connection with the driver or control center in emergency intercom mode. The broadcasting system includes a broadcasting control unit and a passenger room amplifier unit. The passenger room amplifier unit is used to receive noise level parameters and adjust the output volume of the passenger room amplifier unit based on the noise level parameters in non-emergency intercom situations.

[0005] Preferably, The noise detection module also includes: using the microphone unit in the passenger emergency alarm module to collect ambient noise signals in non-emergency intercom mode to avoid microphone channel conflicts.

[0006] Preferably, The broadcasting system also includes: the noise detection module in the integrated passenger alarm transmits the generated noise level parameters to the passenger compartment amplifier unit via Ethernet communication in order to adjust the output volume of the passenger compartment amplifier unit.

[0007] The present invention also provides an integrated passenger alarm device, comprising: a memory, a processor, and an integrated passenger alarm program stored in the memory and executable on the processor, wherein the integrated passenger alarm program, when executed by the processor, implements an integrated passenger alarm.

[0008] The present invention also provides a computer program product, including an integrated passenger alarm program, which, when executed by a processor, implements the integrated passenger alarm device.

[0009] The beneficial effects of this invention are as follows: This invention integrates the noise detection module into the passenger emergency alarm, reuses the microphone resources, and realizes the real-time acquisition function of ambient noise in the carriage. This saves the space and wiring resources required for the independent deployment of noise acquisition devices in traditional technologies, and improves the structural integration and maintenance convenience of the passenger alarm.

[0010] This invention identifies whether the passenger emergency alarm module is in intercom mode through the broadcast control unit. When in intercom mode, the broadcast volume adjustment function is automatically turned off, and the broadcast volume adjustment logic is automatically restored after the intercom ends. This realizes the state mutual sensing control between the broadcast system and the alarm passenger alarm, avoids voice information conflict and interruption caused by the separation of control logic, and improves the clarity of passenger information reception and the continuity of passenger alarm response.

[0013] Figure 2 This is an intention to automatically adjust the broadcast volume of a first embodiment of an integrated passenger alarm device according to the present invention.

[0014] Figure 3 This is a schematic diagram of an integrated passenger alarm device according to the present invention. Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example 1: As Figure 1 The diagram shown is a flowchart of the first embodiment of the integrated passenger alarm of the present invention, which presents the first embodiment of the integrated passenger alarm of the present invention.

[0017] In the first embodiment, the integrated passenger alarm includes: The noise detection module is used to collect ambient noise signals in the passenger room in real time during non-emergency intercom use and generate corresponding noise level parameters. The passenger emergency alarm module includes an alarm triggering unit and a microphone unit. The alarm triggering unit is used to respond to the passenger's alarm operation. The microphone unit is used to establish a two-way voice communication connection with the driver or control center in emergency intercom mode. The broadcasting system includes a broadcasting control unit and a passenger room amplifier unit. The passenger room amplifier unit is used to receive noise level parameters and adjust the output volume of the passenger room amplifier unit based on the noise level parameters in non-emergency intercom situations.

[0018] It should be noted that the "non-emergency intercom state" and "emergency intercom state" in this embodiment are two mutually exclusive states for the passenger alarm. When the alarm module is not triggered and there is no passenger request, the passenger alarm is in the non-emergency intercom state, and the broadcast volume can be dynamically adjusted according to the ambient noise. Once the alarm triggering unit is activated, the passenger alarm enters the emergency intercom state, and the broadcast volume adjustment function must be temporarily suspended to prevent the broadcast signal from interfering with the communication quality between the passenger and the driver. The passenger alarm also includes a button indicator light unit to display the current status of the alarm.

[0019] It should be noted that noise signals are collected in real time by a noise detector integrated in the PECU (Passenger Information System), and the cabin noise level is output to the SCU amplifier. The cabin amplifier adjusts the cabin broadcast volume in real time based on the feedback noise level. This ensures that the broadcast volume of the cabin speakers is always 5-10 dB higher than the noise level (adjustable), and that the speaker output volume never exceeds 90 dB (adjustable) at any time.

[0020] Understandably, by integrating the noise detection module's function (microphone unit) into the passenger emergency alarm module and setting up independent or shared microphone channels, the problem of broadcast adjustment function failure caused by microphone resource conflicts in the existing technology is effectively avoided, thus achieving a compact device structure and multi-functional integration.

[0021] It should be understood that, compared to the existing technology where broadcast volume adjustment relies on an independent noise acquisition device and cannot coordinate with the alarm passenger alarm, this invention constructs a complete intercom-broadcast control closed-loop logic through state perception + control logic decoupling + communication link unification. This significantly improves the intelligence level of the passenger alarm while ensuring the clarity of voice calls and the accessibility of broadcast information.

[0022] For example, such as Figure 2 As shown, the passenger emergency alarm is equipped with a microphone for intercom communication between passengers and the driver / OCC in emergencies. When the passenger emergency alarm is not in intercom mode, the noise detection module acquires the ambient noise level in the passenger compartment under preset conditions. The noise signal is then transmitted via Ethernet to the passenger compartment amplifier unit to adjust the volume of announcements within the passenger compartment.

[0023] Example 2: Furthermore, the present invention provides an integrated passenger alarm device, employing one of the integrated passenger alarm devices described in the above embodiments, which can solve the technical problem of integrated passenger alarms.
