[0002] With the rapid urbanization in my country, more and more people are moving to urban areas. In the face of frequent natural disasters and violations of rules and regulations, timely and effective early warning is of paramount importance to the safety of people's lives and property. However, existing alarms require dedicated power lines, resulting in high power consumption and line loss in their internal circuitry. Furthermore, the operating voltage significantly affects the alarm's performance, sometimes preventing it from issuing alarm signals promptly. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect of existing alarms that cannot issue alarm signals in a timely manner due to the influence of high and low operating voltage, thereby providing an alarm.

[0025] Example

[0026] This invention provides an alarm device applicable to situations requiring the use of an alarm signal to alert in cases of fire, gas leak, unauthorized entry, or other unusual events. Figure 1 As shown, it includes: a carrier signaling polarity conversion module 1, a decoding module 2, a control module 3, an alarm module 4, and a power supply module 5, wherein,

[0027] The carrier signaling polarity conversion module 1 is used to acquire carrier signaling and convert it into positive polarity carrier signaling.

[0028] The alarm is connected to the controller of the external alarm. In the event of an emergency such as a fire, gas leak, or unauthorized entry, the user sends a carrier signal through the controller. This carrier signal is transmitted to the carrier signal polarity conversion module 1 via the carrier bus. Since the power supply module 5 draws power from the carrier signal to supply power to the control module 3 and the alarm module 4, and since the carrier signal is a positive load wave signal, the carrier signal polarity conversion module 1 converts the carrier signal into a positive polarity carrier signal and then sends it to the decoding module 2 and the power supply module 5 via the carrier bus.

[0029] Decoding module 2 is used to parse the positive polarity carrier signaling to obtain the carrier signal.

[0030] Due to different environmental conditions, the alarm needs to emit alarm signals with different tones, volumes, and flashing frequencies. Users can set different carrier signaling to make the alarm emit corresponding alarm signals. Therefore, the carrier signaling contains the setting requirements for alarm signals. At this time, the decoding module 2 needs to parse the positive carrier signaling and restore it to the alarm content it represents, i.e., the carrier signal, and then send it to the control module 3.

[0031] Control module 3 is used to generate alarm control commands based on carrier signals and / or obtain the status information of the alarm.

[0032] like Figure 2 As shown, control module 3 includes two control units: a first control unit 31 and a second control unit 32. The first control unit 31 is used to acquire corresponding alarm control command information based on the carrier signal, and / or generate alarm operating status inspection instructions. The second control unit 32 is used to generate alarm control commands based on the alarm control command information, and / or acquire alarm status information based on the alarm operating status inspection instructions.

[0033] Because the on-site environment varies, the alarm content contained in the carrier signaling differs. Therefore, the first control unit 31 needs to obtain the corresponding alarm control command information based on the carrier signal and send it to the second control unit 32 by outputting a strobe pulse. The second control unit 32 stores various tones suitable for different environmental needs, such as fire truck, police car, and police car sounds. The second control unit 32 selects different alarm signal tones according to the strobe pulse and simultaneously issues alarm control commands corresponding to sound alarm signals with different tones and volumes, as well as alarm control commands corresponding to light alarm signals with different flashing frequencies, based on the strobe pulse.

[0034] In addition, when the user needs to check the operating status of the alarm, the decoding module 2 parses the positive polarity carrier signaling issued by the alarm controller and sends it to the control module 3. The first control unit 31 outputs a strobe pulse according to the carrier signal and sends it to the second control unit 32. The second control unit 32 obtains the status information of the alarm according to the alarm operating status inspection command corresponding to the address of the strobe pulse.

[0035] Alarm module 4 is used to issue corresponding alarm signals according to alarm control commands.

[0036] like Figure 2 As shown, the alarm module 4 includes a sound alarm unit 41, used to issue a sound alarm signal according to the alarm control command. A light alarm unit 42 is used to issue a light alarm signal according to the alarm control command.

[0037] The second control unit 32 is connected to the alarm module 4. The second control unit 32 outputs different alarm control commands based on the strobe pulse address, controlling the sound alarm unit 41 to emit sound alarm signals of different pitches and volumes, and controlling the light alarm unit 42 to emit light alarm signals of different flashing frequencies. In one specific embodiment, the second control unit 32 emits alarm control commands corresponding to sound alarm signals of different volumes by changing the duty cycle of the alarm control commands.

[0038] In this embodiment of the invention, both the first control unit 31 and the second control unit 32 can be microcontrollers; this is merely an example and not a limitation. The second control unit 32 can adjust the volume of the sound alarm signal by changing the duty cycle of the PWM pulse of the alarm control command. The second control unit 32 includes a timer; by changing the preset timing period of the timer, the second control unit 32 issues alarm control commands corresponding to light alarm signals with different flashing frequencies, thereby controlling the light alarm unit 42 to emit light alarm signals with different flashing frequencies.

[0039] To meet the needs of various environmental alarm signals, the alarm module 4 can include a variety of alarm units, such as a multi-color light alarm unit 42 and a multi-sound alarm unit. Therefore, in order to improve the load capacity of the alarm, the control module 3 can drive multiple alarm units in a time-sharing or simultaneous manner as needed, thereby reducing the peak current, preventing the overcurrent protection of the carrier bus from malfunctioning, and improving the reliability of the alarm.

[0040] Most existing alarms require a dedicated power supply, and the voltage at which they operate significantly affects their performance. In this invention, as shown in the embodiments... Figure 2 As shown, in order to obtain a stable operating voltage, an RC current-limiting energy storage circuit (power supply module 5) is set to draw power from the carrier line to obtain the carrier voltage, and convert the carrier voltage into the corresponding power supply voltage of control module 3 and alarm module 4, thereby limiting the peak operating current, avoiding large current surges during power-on or operation, and reducing power consumption and voltage loss. It does not impact the controller output protection circuit and avoids false alarms.

[0041] like Figure 3 As shown, the alarm also includes a return code module 6, which is used to send the status information of the alarm obtained by the control module 3 to the carrier signaling polarity conversion module 1.

[0042] like Figure 3 As shown, the feedback module 6 is connected to the first control unit 31. When the user needs to inspect the operating status of the alarm, the control module 3 obtains the status information of the alarm, which includes electrical parameters such as the alarm's operating voltage and operating current. The control module 3 sends the status information of the alarm to the feedback module 6, which then transmits it back to the controller of the external alarm by pulling the current between the carrier buses.

[0043] It should be noted that the decoding method, the code return method, and the method for generating alarm control commands involved in the decoding module 2, the code return module 6, and the control module 3 in the embodiments of the present invention are all methods or algorithms in the prior art, and the corresponding functions can be achieved by integrating existing algorithms into hardware devices such as chips.

[0044] This invention provides specific circuit structures for each module within the alarm, such as... Figures 4(a)-4(c) As shown, the carrier signal output by the controller of the peripheral alarm enters from the L1 and L2 terminals through the D1 and D3 carrier signal polarity conversion circuits. One path passes through the D5, R1, C1, and U4 current-limiting energy storage circuits to generate the low-voltage power required by the control module 3, and the other path passes through the D9, R30, and C30 current-limiting energy storage circuits to generate the high-voltage power required by the alarm module 4.

[0045] like Figures 4(a)-4(b)As shown, after the positive polarity carrier signal is parsed by the decoding module 2 composed of the switching transistor Q2, the carrier signal is serially input to pin 11 of the microcontroller U1. The I / O port of the microcontroller U1 outputs a strobe pulse train connected to the microcontroller U5. Figures 4(b)-4(c) One pin of microcontroller U5 is connected to the switching transistors Q5 and Q8 of the light alarm unit 42, thereby driving the LED flashing with constant current. This constant current drive makes the alarm low-power and high-efficiency, widely adaptable to unstable line voltages, and avoids under-driving or over-driving, ensuring high reliability. The other PWM pin of microcontroller U5 is connected to the switching transistors Q6 and L31 of the sound alarm unit 41, thereby boosting the piezoelectric buzzer. Figures 4(a)-4(b) As shown, the alarm's operating status signal is output through pins 8 and 9 of the microcontroller U1, driving the switching transistor Q3 of the feedback module 6, and transmitting it back to the alarm controller of the peripheral device by pulling the current between the carrier buses.

[0046] The alarm provided in this embodiment of the invention is connected to the controller of an external alarm. By setting up a power supply module, it draws power from the carrier signaling issued by the alarm controller, limiting the current peak and avoiding large current surges during power-on or operation, thus reducing power consumption and voltage loss. This avoids the defect of the alarm failing to issue alarm signals in a timely manner due to variations in operating voltage, simplifying the alarm circuit design. A decoding module is set up to parse the carrier signaling to obtain the carrier signal, which is then sent to the control module. This allows the control module to control the alarm module to issue an alarm signal, enabling the alarm to sound promptly. The control module can control the two alarm units in a time-sharing or simultaneous manner, thereby increasing the alarm's load-bearing capacity, reducing the peak operating current during alarm, preventing overcurrent protection malfunctions on the carrier bus, and reducing engineering construction requirements and costs. The control module can issue alarm control commands tailored to different site environments, increasing the alarm's adaptability. The control module monitors the alarm's operating status according to the alarm's operational status inspection commands, ensuring reliable operation of the alarm.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
