Description

Technical Field

[0001] This utility model relates to the field of safety and fire alarm technology, and in particular to an audible and visual alarm device. Background Technology

[0002] In industrial plants, residential communities, and other similar settings, remote audible and visual alarm devices are a common technical means of providing early warnings of abnormal events (such as safety hazards and emergency situations). Currently, traditional remote audible and visual alarms generally employ fixed warning modes or single-intensity sound output designs. Their core logic is to transmit alarm trigger information to personnel within the area through audible and visual signals with fixed parameters, such as a constant-loud alarm tone or a fixed-state indicator light.

[0003] However, such traditional solutions have limitations in adaptability to different scenarios: on the one hand, the warning scenarios, related personnel, and nature of events involved in factory and residential scenarios vary in multiple dimensions, and a single sound and light output cannot accurately distinguish between different levels of warning events; on the other hand, due to the lack of graded warning capabilities, on-site personnel cannot determine the level of warning events by associating information such as alarm sound intensity and indicator light status, which leads to problems such as over-handling of emergency response resulting in waste of resources or under-handling of emergency response delaying the handling of dangerous situations. In extreme scenarios, the lack of graded warning may even lead to major property losses or safety accidents. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an audible and visual alarm device that saves resources and improves work efficiency by using graded alarms.

[0005] This utility model discloses an audible and visual alarm device, the audible and visual alarm device comprising:

[0006] The monitoring unit is used to convert the acquired image data into digital signals;

One of the several PWM output modules generates a low-frequency alarm signal based on a first electrical signal.

[0013] In one or more embodiments of this utility model, the alarm unit includes several sets of indicator lights, a high-pitched buzzer, and a low-pitched buzzer. The several sets of indicator lights are connected to the eight-channel relay to generate light signals according to a first point signal or a second electrical signal. The low-pitched buzzer is connected to the several sets of PWM output modules to generate a low-pitched buzzing sound according to a low-pitched alarm signal.

[0016] In one or more embodiments of this utility model, the PWM output module is model YF-6-DC-7-24V.

[0017] In one or more embodiments of this utility model, the network connection module is model TAS-IO-428RI.

[0018] The beneficial effects of this utility model are as follows: This utility model achieves a graded alarm function through the collaborative structure of the monitoring unit, the switching unit, the control unit, and the alarm unit: the first / second electrical signal generated by the switching unit, in conjunction with different PWM output modules of the control unit, enables the alarm unit to output high and low frequency buzzer sounds and corresponding light signals, accurately distinguishing different levels of warning events; among them, the three PWM output modules can output three different low frequency alarm signals according to the first electrical signal, thereby controlling the intensity of the low frequency buzzer; the corresponding on / off state of the relay module is controlled by remote level data, thereby controlling the warning state of the three indicator lights and the working state of a high frequency buzzer.

This avoids the resource waste and response delays caused by traditional single outputs, effectively improving emergency response efficiency and reducing the risk of property loss.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] It should be noted that, unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] As described in the background section, existing audible and visual alarm devices often only have one alarm mode, which makes it impossible for relevant personnel to take appropriate measures based on the alarm mode.

[0026] For the above issues, please refer to the appendix. Figure 1 As shown, the audible and visual alarm device of this utility model consists of four parts: a monitoring unit 100, a switching unit 200, a control unit 300, and an alarm unit 400. The units are connected by circuits to form a complete alarm system.

[0027] In a further embodiment, the monitoring unit 100 includes a first camera 12, a second camera 13, a third camera 14, and a server 11. All three cameras are electrically connected to the server 11 and can collect image data from different areas and transmit it to the server 11. The server 11 is responsible for converting the image data into digital signals.

[0028] In a further embodiment, the switching unit 200 consists of a network connection module 21 of model TAS-IO-428RI and an eight-channel relay 22. The input terminal of the network connection module 21 is connected to the server 11 and can generate control signals according to the digital signals of the server 11. The input terminal of the eight-channel relay 22 is connected to the output terminal of the network connection module 21 and can generate a first electrical signal and a second electrical signal according to the control signal.

[0029] In a further embodiment, the control unit 300 includes a wiring adapter module 31 and several sets of YF-6-DC-7-24V PWM output modules, specifically a first PWM output module 32, a second PWM output module 33, and a third PWM output module 34. The input terminal of the wiring adapter module 31 is connected to the output terminal of the eight-channel relay 22, and its output terminal is connected to the input terminal of each PWM output module. One set of PWM output modules can generate a low-frequency alarm signal based on the first electrical signal.

[0030] In a further embodiment, the alarm unit 400 consists of several sets of indicator lights, a high-pitched buzzer 44, and a low-pitched buzzer 45. The indicator lights are connected to an eight-channel relay 22 and can generate light signals based on a first or second electrical signal. The low-pitched buzzer 45 is connected to each PWM output module and can generate a low-pitched buzzing sound based on a low-pitched alarm signal. The high-pitched buzzer 44 is connected to the eight-channel relay 22 and generates a high-pitched buzzing sound based on a second electrical signal. In this embodiment, the indicator lights include a red first indicator light 41, a yellow second indicator light 42, and a green third indicator light 43. Based on the output of three different low-pitched alarm signals from the first PWM output module 32, the second PWM output module 33, and the third PWM output module 34, the first indicator light 41, the yellow second indicator light 42, and the green third indicator light 43 indicate different light signals. In this embodiment, the circuits or devices that realize the functions of the monitoring unit 100, the switching unit 200, the control unit 300, and the alarm unit 400 are all existing structures and will not be described in detail here.

[0031] In this embodiment, the first camera 12, the second camera 13, and the third camera 14 can be deployed in factory cameras, community cameras, and public areas. They can be used to detect electric bicycles entering elevators, whether safety helmets are worn, whether personnel are entering restricted areas, and whether there is open flame, etc. Different alarm levels are assigned based on the different states, and different alarm signals are transmitted to the network connection module 21 via the server 11. The network connection module 21 controls eight relays 22 to control indicator lights and the PWM output module, which in turn controls a low-frequency buzzer 45. The status of the indicator lights and buzzer indicates the corresponding level of the event, allowing for pre-defined handling measures and timely, efficient emergency response. When a warning event occurs, personnel can determine the level of the warning event based on the alarm intensity or indicator light status, and then take appropriate emergency measures accordingly. This efficient and accurate handling of related hazards saves resources, improves work efficiency, and achieves intelligent and standardized warning mechanisms.

[0032] Workflow: First, the first camera 12, second camera 13, and third camera 14 of the monitoring unit 100 acquire on-site image data and transmit it to the server 11. The server 11 converts the image data into digital signals and sends them to the network connection module 21 (model TAS-IO-428RI) in the switch unit 200. The network connection module 21 generates control signals based on the received digital signals and transmits them to the eight-channel relay 22. The eight-channel relay 22 generates a first electrical signal or a second electrical signal based on the control signals. When the first electrical signal is generated, it is transmitted to several sets of indicator lights in the alarm unit 400 to generate light signals; on the other hand, it is transmitted to the wiring adapter module 31 of the control unit 300. The wiring adapter module 31 transmits the signal to one of the first PWM output module 32, the second PWM output module 33, or the third PWM output module 34. These YF-6-DC-7-24V PWM output modules generate different low-frequency alarm signals based on different values ​​of the first electrical signal. The low-frequency buzzer 45 receives the signal and generates a corresponding low-frequency buzzer sound. When the eight-channel relay 22 generates the second electrical signal, this signal is transmitted to several sets of indicator lights and the high-pitched buzzer 44 in the alarm unit 400, causing the indicator lights to generate light signals and the high-pitched buzzer 44 to generate a high-pitched buzzing sound. Through the above process, the device realizes the function of outputting different audible and visual alarm signals according to different electrical signals, thus completing the hierarchical alarm.

[0033] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
