Description

[0001] The disclosure relates to an alarm device, and more particularly to a wireless audio-visual alarm device.

[0002] In recent years, with the development of the Internet of Things (IoT), conventional alarm devices equipped with wireless communication capabilities have become increasingly common. Due to their ease of operation and low cost, these conventional alarm devices are utilized in various applications.

[0003] Referring to FIG. 1, a conventional alarm device includes a processor 91, a light-emitting diode (LED) 92 and a speaker 93. The conventional alarm device is configured to receive a trigger signal (e.g., a signal from a sensor (not shown) detecting presence of, for example, a person or smoke). The processor 91, in response to receipt of the trigger signal, generates a driving signal and an audio signal, and transmits the driving signal and the audio signal respectively to the LED 92 and the speaker 93. The LED 92, in response to receipt of the driving signal, emits light based on the driving signal; the speaker 93, in response to receipt of the audio signal, outputs an alarm sound based on the audio signal.

[0004] However, the conventional alarm device is only able to output a single type of alarm sound, and the content of the alarm sound is fixed and not adjustable. As a result, the conventional alarm device can only produce one type of audio-visual effect, making the conventional alarm device difficult to accommodate multiple usage scenarios at the same time.

[0005] Therefore, an object of the disclosure is to provide an alarm device that can alleviate at least one of the drawbacks of the prior art.

[0006] According to an aspect of the disclosure, there is provided an alarm device according to claim 1.

[0007] Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiment(s) with reference to the accompanying drawings. It is noted that various features may not be drawn to scale. FIG. 1 is a block diagram of a conventional alarm device. FIG. 2 is a block diagram of an alarm device according to an embodiment of the present disclosure. FIG. 3 is a side view of the alarm device according to an embodiment of the present disclosure.

[0008] Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.

[0009] Referring to FIGS. 2 and 3, an alarm device according to an embodiment of the present disclosure includes a housing 7, a control module 1, a storage module 3, a sound module 2 electrically connected to the control module 1 and the storage module 3, a lighting module 4 electrically connected to the control module 1, a power module 51 electrically connected to a power supply, a battery module 52 electrically connected to the power module 51, and an indicator 61, a button 62 and an input terminal 63 that are electrically connected to the control module 1. The power module 51 is further electrically connected to the control module 1, the sound module 2, the lighting module 4, the indicator 61, the button 62 and the input terminal 63 for supplying electric power thereto.

[0010] The control module 1 receives a plurality of trigger signals, a stop signal, a volume control signal, and an external control signal through a wireless communication network 81. The control module 1 may be connected to at least one external electronic element (not shown) through the wireless communication network 81 for receiving the trigger signals and the stop signal from the external electronic element. The external electronic element may be exemplified as, for example, a motion sensor, a smoke sensor, a proximity sensor, or a combination thereof, but this disclosure is not limited in this respect. Further, the control module 1 may receive the volume control signal and the external control signal from a remote control through the wireless communication network 81. In this embodiment, a number of the trigger signals that can be received by the control module 1 is four, but the disclosure is not limited to such.

[0011] The control module 1 is configured to output a plurality of sound selection signals that correspond respectively to the trigger signals. The control module 1 is further configured to output a plurality of light-on signals that correspond respectively to the trigger signals. Specifically, when the control module 1 receives one of the trigger signals, the control module 1 outputs a corresponding one of the sound selection signals and a corresponding one of the light-on signals. In this embodiment, since the number of trigger signals that may be received by the control module 1 is four, a number of the sound selection signals which the control module 1 can output is four, and a number of the light-on signals which the control module 1 can output is also four. When the control module 1 receives the stop signal, the control module 1 outputs an audio-stop signal to the sound module 2, and a light-stop signal to the lighting module 4. When the control module 1 receives the volume control signal, the control module 1 outputs a volume adjustment signal to the sound module 2.

[0012] The control module 1 may be exemplified by, for example, a microcontroller. In this embodiment, the control module 1 is exemplified as a STM32WLE5CC chip, but the disclosure is not limited to this example. The STM32WLE5CC chip uses LoRa ®< (Long Range) communication technology to communicate with the wireless communication network 81.

[0013] The storage module 3 includes a data input port 31 disposed on the housing 7, and a memory 32 electrically connected to the data input port 31. The data input port 31 receives a plurality of audio data sets from an external device, and the memory 32 stores the audio data sets received through the data input port 31. The audio data sets are related respectively to the sound selection signals. The audio data sets may be audio files in the format of, for example, MP3 or WMA, but the disclosure is not limited to such. In this embodiment, the data input port 31 is exemplified as an interface in compliance with Universal Serial Bus (USB) type-C port (receptacle), but the disclosure is not limited to such; the external device may be exemplified as a computer, a smart phone, or a USB-C flash drive that has a USB Type-C interface for connecting with the data input port 31. The memory 32 is exemplified as a flash memory device (e.g., EN25QH128A that is a 128 megabit serial flash memory), but the disclosure is not limited to such. In this embodiment, a number of the audio data sets received through the data input port 31 and stored by the memory 32 is four, but the disclosure is not limited to such.

[0014] The sound module 2 includes an audio processing unit 21 electrically connected to the control module 1 through, for example, a universal asynchronous receiver / transmitter (UART) interface, and to the memory 32 through, for example, a serial peripheral interface (SPI) bus. The sound module 2 further includes an audio amplifier 22 electrically connected to the audio processing unit 21, and a speaker 23 electrically connected to the audio amplifier 22. In this embodiment, the audio processing unit 21 is exemplified as an audio decoder chip (e.g., YX9100), but the disclosure is not limited to such. The audio amplifier 22 is exemplified as an audio power amplifier chip (e.g., 8002), but the disclosure is not limited to such. In some embodiments, the audio processing unit 21 and the audio amplifier 22 may be electrically connected to the data input port 31, which is a USB Type-C port, and the data input port 31 may receive electric power from an external power source that is connected to the data input port 31 and provide electric power to the audio processing unit 21 and the audio amplifier 22.

[0015] In this embodiment, when the audio processing unit 21 receives the corresponding one of the sound selection signals from the control module 1, the audio processing unit 21 obtains one of the audio data sets that is related to the corresponding one of the sound selection signals from the memory 32, generates an audio signal based on said one of the audio data sets thus obtained (i.e., decoding the audio data set), and transmits the audio signal to the audio amplifier 22. The audio amplifier 22, in response to receipt of the audio signal, amplifies the audio signal thus received and transmits the audio signal thus amplified to the speaker 23. The speaker 23 then generates an alarm sound based on the audio signal received from the audio amplifier 22. The audio processing unit 21 further receives the volume adjustment signal from the control module 1, and controls a degree of audio amplification of the audio amplifier 22 so as to control an amplitude of the audio signal that is amplified by the audio amplifier 22, thereby controlling a volume of the alarm sound that is generated by the speaker 23.

[0016] The lighting module 4 includes a driving unit 41 electrically connected to the control module 1, and a plurality of lighting units 42 (e.g., six as shown in FIG. 3) electrically connected to the driving unit 41, but a number of the lighting units 42 is not limited to such. The lighting units 42 are disposed on the housing 7 (as shown in FIG. 3), and each of the lighting units 42 is able to emit light of different colors. In this embodiment, each of the lighting units 42 is exemplified as a light-emitting diode (LED) light that is able to emit light of different colors, and the driving unit 41 is an LED driver for driving the lighting units 42 (e.g., a WS2811 LED driver integrated circuit (IC)). However, the driving unit 41 and the lighting units 42 are not limited to the examples of this disclosure. According to the present disclosure, the light-on signals are related respectively to a plurality of lighting patterns. The driving unit 41 is configured to, in response to receipt of the corresponding one of the light-on signals, control the lighting units 42 to emit light with a corresponding one of the lighting patterns based on the corresponding one of the light-on signals. In this embodiment, the light-on signals are related respectively to four lighting patterns.

[0017] Examples of the four lighting patterns are as follows: a first one of the lighting patterns, where the driving unit 41 drives the lighting units 42 sequentially in a clockwise direction to emit light one by one in the order of red, green, blue, red, green, blue until all the lighting units 42 are emitting light, and once all the lighting units 42 are emitting light, the driving unit 41 drives the lighting units 42 to stop emitting light sequentially in the clockwise direction one by one; a second one of the lighting patterns, where the driving unit 41 drives the lighting units 42 to sequentially emit light in a counter-clockwise direction to emit light one by one in the order of red, green, blue, red, green, blue until all the lighting units 42 are emitting light, and when all the lighting units 42 are emitting light, the driving unit 41 drives the lighting units 42 to stop emitting light sequentially in a counter-clockwise direction one by one; a third one of the lighting patterns, where the driving unit 41 drives the lighting units 42 to simultaneously emit light, in which three of the lighting units 42 are driven to emit red color light, and the other three of the lighting units 42 are driven to emit green color light; and a fourth one of the lighting patterns, where the driving unit 41 drives the lighting units 42 to simultaneously emit light, in which three of the lighting units 42 are driven to emit green color light, and the other three of the lighting units 42 are driven to emit blue color light. In some embodiments, the light-on signals may be programmable such that each of the lighting patterns can be varied.

[0018] The power module 51 includes a DC-to-DC converter 511 electrically connected to the power supply for receiving direct current (DC) power therefrom, a linear voltage regulator 512 electrically connected to the DC-to-DC converter 511, a first switch 513 electrically connected to the DC-to-DC converter 511, the audio processing unit 21 and the audio amplifier 22, and a second switch 514 electrically connected to the DC-to-DC converter 511, the lighting units 42 and the driving unit 41. In this embodiment, the DC-to-DC converter 511 is exemplified as an MP2451 step-down switching regulator, but the disclosure is not limited to such. The linear voltage regulator 512 is exemplified as a CE6232B33M voltage regulator, but the disclosure is not limited to such.

[0019] The DC-to-DC converter 511 receives the DC power that is a 12 V DC power from the power supply, converts the DC power into a first voltage power of 5 V, and outputs the first voltage power to the linear voltage regulator 512, the driving unit 41, the lighting units 42, the audio processing unit 21, and the audio amplifier 22. The linear voltage regulator 512 receives the first voltage power from the DC-to-DC converter 511, regulates the first voltage power thus received to produce a second voltage power of 3.3 V, and outputs the second voltage power to the control module 1. Each of the first switch 513 and the second switch 514 is electrically connected to the control module 1, and is controlled by the control module 1 to switch between a conducting state and a non-conducting state. For example, when the control module 1 receives the trigger signals, the control module 1 switches each of the first switch 513 and the second switch 514 into the conducting state from a default setting where the first switch 513 and the second switch 514 are in the non-conducting state for power saving; when the control module 1 receives the stop signal, the control module 1 switches each of the first switch 513 and the second switch 514 to the non-conducting state, such that the DC-to-DC converter 511 cannot output the first voltage power to the audio processing unit 21, the audio amplifier 22, the driving unit 41 and the lighting units 42. Specifically, the DC-to-DC converter 511 outputs the first voltage power to the audio processing unit 21 and the audio amplifier 22 through the first switch 513 when the first switch 513 is in the conducting state, and outputs the first voltage power to the driving unit 41 and the lighting units 42 through the second switch 514 when the second switch 514 is in the conducting state.

[0020] The battery module 52 includes a battery control unit 521 electrically connected to the DC-to-DC converter 511, a transformer circuit 522 electrically connected to the DC-to-DC converter 511 and the linear voltage regulator 512, a battery monitor 523 electrically connected to the linear voltage regulator 512, and a battery 524 electrically connected to the battery control unit 521, the transformer circuit 522 and the battery monitor 523. In this embodiment, the battery 524 is exemplified by a plurality of nickel-metal hydride (NiMH) batteries connected in series (e.g., three NiMH batteries), and supplies a backup power of 3.7 V to 4.2 V, but the disclosure is not limited to such. The battery control unit 521 is exemplified as a CN3085 NiMH power management chip, but the disclosure is not limited to such. The transformer circuit 522 is exemplified as an MT3608 step-up converter chip, but the disclosure is not limited to such. The battery monitor 523 is exemplified as a CN312 battery monitor chip, but the disclosure is not limited to such.

[0021] The battery 524 is operable to switch between a charging state and a discharging state. When the battery 524 is in the charging state, the battery 524 is charged using the first voltage power outputted by the DC-to-DC converter 511 through the battery control unit 521. When the battery 524 is in the discharging state, the battery 524 supplies the backup power to the transformer circuit 522, and the transformer circuit 522 converts the backup power into a backup voltage power of 5 V that is used to power the control module 1, the sound module 2, and the lighting module 4. In this embodiment, the battery control unit 521 controls the battery 524 to switch between the charging state and the discharging state. Specifically, in a case where the DC-to-DC converter 511 is connected to the power supply and outputs the first voltage power to the battery control unit 521, the battery control unit 521 switches the battery 524 to the charging state and charges the battery 524 using the first voltage power; on the other hand, in a case where the DC power that is supplied from the power supply to the power module 51 is cut off, causing the DC-to-DC converter 511 to not be able to supply the first voltage power, the battery control unit 521 switches the battery 524 to the discharging state for supplying the backup power to the transformer circuit 522, and the transformer circuit 522 outputs the backup voltage power as a substitute to the first voltage power for powering the sound module 2, the lighting module 4, and the control module 1. In this embodiment, the backup voltage power is supplied to the sound module 2 and the lighting module 4, and is regulated and supplied to the control module 1 by the linear voltage regulator 512. In some embodiments, the transformer circuit 522 is electrically connected to the sound module 2 and the lighting module 4, and the backup voltage power outputted by the transformer circuit 522 is directly provided to the sound module 2 and the lighting module 4. The battery monitor 523 receives the second voltage power from the linear voltage regulator 512 to be powered thereby, monitors a voltage value of the backup power outputted by the battery 524, and stops the battery 524 from supplying the backup power when the voltage value of the backup power is less than a predetermined voltage value, so as to prevent the battery 524 from over-discharging, which may lead to reduced performance, damage, or even permanent failure of the battery 524. In this embodiment, the predetermined voltage value is set to be 3 V, but the disclosure is not limited to such.

[0022] The indicator 61 is disposed on the housing 7, and is electrically connected to the control module 1 through a general-purpose input / output (GPIO) interface. The indicator 61 receives the second voltage power from the linear voltage regulator 512 to be powered thereby, and is used to indicate a charging status of the battery 524. In some embodiments, the battery control unit 521 may be electrically connected to the control module 1 for the battery control unit 521 to transmit to the control module 1 a charging-on signal that indicates the battery 524 is in the charging state. Specifically, when the battery 524 is in the charging state, the control module 1 controls the indicator 61 to emit light in a blinking manner (e.g., flashes once every 5 seconds). In this embodiment, the indicator 61 is exemplified as an LED, but the disclosure is not limited to such.

[0023] The button 62 is disposed on the housing 7, and is electrically connected to the control module 1 through the GPIO interface. The button 62 receives the second voltage power from the linear voltage regulator 512 to be powered thereby, and is used in cooperation with the indicator 61 to indicate a connection status between the control module 1 and the wireless communication network 81. Specifically, when the button 62 is pressed and the control module 1 is connected to the wireless communication network 81, the control module 1 controls the indicator 61 to flash once.

[0024] The input terminal 63 is electrically connected to the control module 1 through the GPIO interface. The input terminal 63 receives the second voltage power from the linear voltage regulator 512 to be powered thereby, and is used for receiving the external control signal in a wired manner. In some embodiments, the external control signal is used for troubleshooting and checking of the alarm system of this disclosure. The input terminal 63 may be exemplified as a dry contact, but the disclosure is not limited to such. For example, the input terminal 63 is a switch, a relay switch, a reed switch, etc. Specifically, when the control module 1 receives the external control signal through the input terminal 63 or through the wireless communication network 81, the control module 1 may perform operations according to the external control signal. For example, when an operator wishes to check if the lighting units 42 are working, the operator may transmit the external control signal that commands the driving unit 41 to control all the lighting units 42 to emit light at the same time to the control module 1 either wirelessly through the wireless communication network 81 or in the wired manner through the input terminal 63 using, for example, a cable; in response to receipt of the external control signal, the control module 1 performs a light-check operation of controlling the driving unit 41 to drive all the lighting units 42 to emit light according to the external control signal, but the disclosure is not limited in this respect.

[0025] When the control module 1 receives the stop signal, the control module 1 outputs the audio-stop signal to the audio processing unit 21, and outputs the light-stop signal to the driving unit 41. When the audio processing unit 21 receives the audio-stop signal, the audio processing unit 21 stops generating the audio signal, which causes the speaker 23 to stop generating the alarm sound. When the driving unit 41 receives the light-stop signal, the driving unit 41 controls the lighting units 42 to stop emitting light.

[0026] In summary, when the control module 1 receives one of the trigger signals, the control module 1 outputs a corresponding one of the sound selection signals to the audio processing unit 21. The audio processing unit 21 then obtains one of the audio data sets based on the corresponding one of the sound selection signals from the memory 32, and the audio processing unit 21 generates the audio signal based on the one of the audio data sets thus obtained. The speaker 23 then generates the alarm sound based on the audio signal. Additionally, when the control module 1 receives one of the trigger signals, the control module 1 further outputs a corresponding one of the light-on signals to the driving unit 41. The driving unit 41 drives the lighting units 42 to emit light with a corresponding one of the lighting patterns based on the corresponding one of the light-on signals. By virtue of the above arrangements, the alarm device of this disclosure is able to produce multiple types of audio-visual effects, making the alarm device able to accommodate multiple usage scenarios simultaneously.

[0027] In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiment(s). It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details. It should also be appreciated that reference throughout this specification to "one embodiment," "an embodiment," an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects; such does not mean that every one of these features needs to be practiced with the presence of all the other features. In other words, in any described embodiment, when implementation of one or more features or specific details does not affect implementation of another one or more features or specific details, said one or more features may be singled out and practiced alone without said another one or more features or specific details. It should be further noted that one or more features or specific details from one embodiment may be practiced together with one or more features or specific details from another embodiment, where appropriate, in the practice of the disclosure.
