[0001] This utility model relates to the field of alarm technology, and in particular to an intelligent voice alarm. Background Technology

[0002] An alarm is an electronic device that uses sound, light, air pressure, or other means to alert or warn us to take certain actions in order to prevent or mitigate the consequences of an event. Alarms are divided into mechanical alarms and electronic alarms. With the advancement of technology, mechanical alarms are increasingly being replaced by advanced electronic alarms.

[0003] However, current electronic alarms can only issue corresponding alarms on-site in response to one or more specific commands, and cannot identify events in a timely manner, nor are they effective in preventing events. Summary of the Invention

[0004] In order to solve at least one of the technical problems mentioned above, this utility model proposes an intelligent voice alarm device.

[0005] According to some embodiments of this utility model, an intelligent voice alarm is provided. The alarm includes a main control module, a wireless communication module, and a voice interaction module. The main control module includes a SoC chip, which is connected to a first audio input interface and a first audio output interface. The SoC chip is used to convert analog audio signals received by the first audio input interface into digital audio signals and send them to the wireless communication module, and to convert digital audio signals received by the wireless communication module into analog audio signals and send them to the first audio output interface. The wireless communication module includes a wireless communication chip electrically connected to the SoC chip, and the wireless communication chip is connected to an antenna interface and a SIM card slot. The voice interaction module includes an intelligent voice chip electrically connected to the SoC chip, which is connected to a second audio input interface and a second audio output interface. The intelligent voice chip is used to recognize audio commands received by the second audio input interface and send corresponding audio feedback to the second audio output interface.

[0006] Based on the above scheme, the alarm includes wireless communication and voice interaction functions. The voice interaction module can realize local alarm feedback, automatically recognize voice input and generate voice response. After the alarm is triggered, the alarm can also realize remote alarm calling through the wireless communication module. Based on the wireless communication and voice interaction functions, the alarm integrates local alarm and remote calling functions, improving the intelligence and application comprehensiveness of the alarm.

[0007] In some possible implementations, the alarm further includes a filter module comprising a switched-capacitor filter and a latch; the input and control terminals of the latch are both connected to the SoC chip, the output terminal of the latch is connected to the control terminal of the switched-capacitor filter, the latch is used to send parameter configuration data issued by the SoC chip to the switched-capacitor filter, the filter input terminal of the switched-capacitor filter is electrically connected to the second audio input interface, and the filter output terminal of the switched-capacitor filter is electrically connected to the intelligent voice chip.

[0008] Based on the above scheme, the latch can store the control commands of the SoC chip and send control commands to the switched capacitor filter. The switched capacitor filter responds to the commands sent by the latch by switching the filter parameter configuration, ensuring that the voice interaction module can accurately identify distress messages and alarm messages.

[0009] In some possible implementations, the switched capacitor filter includes at least two second-order filter units, the two second-order filter units are connected in series to form a fourth-order filter, the filter input terminal of the fourth-order filter is electrically connected to the second audio input interface, and the filter output terminal of the fourth-order filter is electrically connected to the intelligent voice chip.

[0010] Based on the above scheme, the switched capacitor filter includes at least two second-order filter units, which can realize a variety of different filtering modes. The two second-order filter units are connected in series to form a fourth-order filter, which can perform fourth-order filtering on the audio signal obtained by the second audio input interface, so that the voice interaction module can accurately identify distress and alarm information.

[0011] In some possible implementations, the alarm also includes indicator lights and buttons, both of which are connected to the SoC chip.

[0012] Based on the above solution, the alarm can be manually triggered by pressing the button, and the indicator light can display the working status of the alarm.

[0013] In some possible implementations, the alarm further includes a power module, which includes a first conversion circuit and a power interface. The output of the first conversion circuit is connected to the main control module, the wireless communication module, the voice interaction module, and the filter module, respectively. The input of the first conversion circuit is connected to the power interface, which is used to connect an external power source.

[0014] Based on the above scheme, the power supply connected to the power interface is converted by the first conversion circuit. The first conversion circuit can convert various forms of power supply, thereby improving the application compatibility of the alarm.

[0015] In some possible implementations, the power module further includes a battery and a second conversion circuit, the output of which is connected to the main control module, the wireless communication module, the voice interaction module, and the filter module, respectively, and the input of which is connected to the battery.

[0016] Based on the above solution, by setting up a battery and a second conversion circuit, the alarm can still work normally when the external power supply is interrupted, thereby improving the stability and reliability of the alarm.

[0017] In some possible implementations, the alarm also includes a network interface that is connected to the SoC chip.

[0018] Based on the above solution, the alarm can be connected to external control devices via a network interface, thereby realizing the function of systematic alarm monitoring.

[0036] Furthermore, to better illustrate this utility model, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this utility model can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this utility model.

[0037] An alarm is an electronic device that uses sound, light, air pressure, or other means to alert or warn us to take certain actions in order to prevent or mitigate the consequences of an event. Alarms are divided into mechanical alarms and electronic alarms. With technological advancements, mechanical alarms are increasingly being replaced by advanced electronic alarms, which are frequently used in areas such as system failures, security, transportation, medical rescue, emergency disaster relief, and sensor detection.

[0038] However, current electronic alarms can only respond to one or more specific commands and issue corresponding alarms on-site, failing to promptly identify incidents and proving ineffective in preventing them. Take bullying as an example: bullying is a persistent problem in schools, often occurring in secluded corners where it's difficult for other students and teachers to detect. Bullying can cause physical harm and severely impact students' mental well-being. In reality, teachers and parents only take bullied students to the hospital for treatment and psychological counseling after a bullying incident has already occurred. Existing alarm technologies typically use audible and visual signals to warn bullies, but this method is not very effective in stopping bullying.

[0039] To address the aforementioned technical problems, this utility model provides an intelligent voice alarm device. Referring to Figures 1 and 2, the intelligent voice alarm device includes a main control module, a wireless communication module, and a voice interaction module. The main control module is electrically connected to both the wireless communication module and the voice interaction module.

[0040] Specifically, the main control module includes a SoC chip 11, which is connected to a first audio input interface 12 and a first audio output interface 13. The SoC chip 11 is used to convert analog audio signals received by the first audio input interface 12 into digital audio signals and send them to the wireless communication module, and to convert digital audio signals received by the wireless communication module into analog audio signals and send them to the first audio output interface 13. The wireless communication module includes a wireless communication chip 21, which is electrically connected to the SoC chip 11 and is connected to an antenna interface 22 and a SIM card slot 23. The voice interaction module includes a smart voice chip 31, which is electrically connected to the SoC chip 11 and is connected to a second audio input interface 32 and a second audio output interface 33. The smart voice chip 31 is used to recognize audio commands received by the second audio input interface 32 and send corresponding audio feedback to the second audio output interface 33.

[0041] Based on the above configuration, the main control module and the voice interaction module work together to achieve local alarm. The voice interaction module can obtain audio input through the second audio input interface 32, and the intelligent voice chip 31 then recognizes the audio input and analyzes whether it meets the alarm conditions. If the audio input meets the alarm conditions, a local warning is issued through the second audio output interface 33. The main control module and the wireless communication module work together to achieve remote alarm call. After the remote alarm call is triggered, the first audio input interface 12 obtains the caller's voice, the SoC chip 11 converts the voice into a digital signal and sends it through the wireless communication module, then converts the received digital signal into an analog signal, and finally transmits it to the connected speaker through the first audio output interface 13. In this case, the main control module and the wireless communication module are essentially voice communicators. In summary, the alarm of this invention includes both wireless communication and voice interaction functions. The voice interaction module realizes local alarm feedback, and the wireless communication module realizes remote alarm calling. Based on the wireless communication and voice interaction functions, the alarm integrates local alarm and remote calling functions, improving the intelligence and comprehensive application of the alarm.

[0042] It should be understood that this embodiment does not limit the specific models of the SoC chip 11, the intelligent voice chip 31, and the wireless communication chip 21. The SoC chip 11 should have voice processing function, for example, the SSC335; while the intelligent voice chip 31 should have voice recognition and voiceprint recognition functions. Preferably, the intelligent voice chip 31 can also have deep learning and neural network functions, for example, the CI1302; the wireless communication chip 21 can be a 4G chip or a 5G chip.

[0043] In some embodiments, referring to Figure 3, the alarm further includes a filter module 4, which includes a switched-capacitor filter 41. The filter input terminal of the switched-capacitor filter 41 is electrically connected to the second audio input interface 32, and the filter output terminal of the switched-capacitor filter 41 is electrically connected to the intelligent voice chip 31. The control terminal of the switched-capacitor filter 41 is connected to the SoC chip 11. Based on the above configuration, the SoC chip 11 sends control commands to the switched-capacitor filter 41 to adjust the filtering mode and frequency band parameters of the switched-capacitor filter 41. The filtering modes include low-pass, high-pass, band-pass, and band-stop. By adjusting the above parameters, the voice interaction module can analyze the target sound and environmental noise to ensure accurate identification of alarm voice or alarm trigger tone.

[0044] In some embodiments, referring to Figure 4, the filter module 4 includes a switched-capacitor filter 41 and a latch 42. The input and control terminals of the latch 42 are both connected to the SoC chip 11, and the output terminal of the latch 42 is connected to the control terminal of the switched-capacitor filter 41. The latch 42 is used to send parameter configuration data from the SoC chip 11 to the switched-capacitor filter 41. The filtering input terminal of the switched-capacitor filter 41 is electrically connected to the second audio input interface 32, and the filtering output terminal of the switched-capacitor filter 41 is electrically connected to the intelligent voice chip 31. Based on the above configuration, the latch 42 can store control commands from the SoC chip 11 and send control commands to the switched-capacitor filter 41. The switched-capacitor filter 41 responds to the commands sent by the latch 42 by switching the filtering parameter configuration, ensuring that the voice interaction module can accurately identify distress and alarm information.

[0045] In this embodiment, the specific model of the switched capacitor filter 41 is not limited. To enhance the filtering effect and improve the application flexibility of the alarm, the switched capacitor filter 41 should have as many filtering modes as possible to facilitate its application in different environments.

[0046] In some embodiments, the switched-capacitor filter 41 includes at least two second-order filter units, which are connected in series to form a fourth-order filter. The filter input terminal of the fourth-order filter is electrically connected to the second audio input interface 32, and the filter output terminal of the fourth-order filter is electrically connected to the intelligent voice chip 31. Based on the above configuration, the switched-capacitor filter 41 includes at least two second-order filter units, enabling various filtering modes. The fourth-order filter formed by connecting two second-order filter units in series allows for fourth-order filtering of the audio signal acquired by the second audio input interface 32, facilitating accurate identification of distress and alarm messages by the voice interaction module. It should be understood that this embodiment does not limit the specific selection of the switched-capacitor filter 41. In one specific implementation, referring to Figure 5, the switched-capacitor filter 41 can be configured as a MAX262.

[0047] In some embodiments, referring to Figure 6, the alarm further includes a power module. The power module includes a first conversion circuit 52 and a power interface 51. The output of the first conversion circuit 52 is connected to the main control module, the wireless communication module, the voice interaction module, and the filter module 4, respectively. The input of the first conversion circuit 52 is connected to the power interface 51, which is used to connect to an external power source. Based on the above configuration, the power interface 51 can be connected to either AC or DC power. The first conversion circuit 52 converts the power source connected to the power interface 51, thus improving the application compatibility of the alarm.

[0048] In a further embodiment, referring to Figure 6, the power module also includes a battery 53 and a second conversion circuit 54. The output of the second conversion circuit 54 is connected to the main control module, the wireless communication module, the voice interaction module, and the filter module 4, respectively, and the input of the second conversion circuit 54 is connected to the battery 53. Based on the above configuration, the battery 53 and the second conversion circuit 54 ensure that the alarm can still work normally when the external power supply is interrupted, thus improving the stability and reliability of the alarm.

[0049] In some embodiments, the alarm also includes a physical interaction component, which allows the user to sound the alarm via methods other than voice. Specifically, the alarm also includes indicator lights and buttons, both of which are connected to the SoC chip 11. Based on the above structure, the user can manually sound the alarm by triggering the button, while the indicator lights can display the alarm's operating status.

[0050] In a specific embodiment, please refer to Figure 2. The indicator light and button described above can be integrated into one unit, i.e., a button with an indicator light. The advantage of setting a button with an indicator light is that when the person alarming presses the button, the light status of the button changes, which can provide intuitive feedback to the person alarming. Furthermore, integrating the indicator light and button also helps to simplify the overall structure of the alarm and reduce its size.

[0051] In some embodiments, referring to Figure 2, the alarm also includes a network interface connected to the SoC chip 11. Based on the network interface, the alarm can connect to external control devices, thereby enabling more functions and enhancing its scalability. For example, in one possible application scenario, multiple alarms can form an alarm monitoring system via a local area network, working in conjunction with a host computer at the monitoring end to achieve systemic alarm monitoring.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
