[0037] To enable those skilled in the art to better understand this solution, the technical solutions in the embodiments of this solution will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this solution, not all of them. Based on the embodiments of this solution, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this solution.

[0038] The term "comprising" and any other variations thereof in the specification, claims, and accompanying drawings of this invention mean "including but not limited to," and are intended to cover a non-exclusive inclusion, not limited to the examples listed herein. Furthermore, the terms "first" and "second," etc., are used to distinguish different objects, not to describe a specific order.

[0039] The implementation of this disclosure will be described in detail below with reference to the specific accompanying drawings:

[0040] Figure 1 This is a schematic diagram of the structure of a building safety early warning system provided in an embodiment of this disclosure. (Refer to...) Figure 1 The building safety early warning system includes: a self-test module 10, a first switch 11, a signal processing module 12, a switch control module 13, a second switch 14, a self-test alarm module 15, a central control module 16, a smoke detection module 17, and an alarm module 18.

[0041] The stationary end of the first switch 11 is connected to the input end of the signal processing module 12, the first moving end of the first switch 11 is connected to the first output end of the self-test module 10, the second moving end of the first switch 11 is connected to the output end of the smoke detection module 17, and the control end of the first switch 11 is connected to the control signal output end of the switch control module 13.

[0042] The stationary end of the second switch 14 is connected to the output end of the signal processing module 12, the first moving end of the second switch 14 is connected to the self-test alarm module 15, the second moving end of the second switch 14 is connected to the central control module 16, and the control end of the second switch 14 is connected to the control signal output end of the switch control module 13.

[0043] The second output terminal of the self-test module 10 is connected to the switch control module 13;

[0044] The central control module 16 is also connected to the input terminal of the alarm module 18.

[0045] In this embodiment, the initial state of the first switch 11 is to connect the output terminal of the smoke detection module 17 and the input terminal of the signal processing module 12, and the initial state of the second switch 14 is to connect the output terminal of the signal processing module 12 and the central control module 16.

[0046] The smoke detection module 17 can be a smoke sensor. The smoke sensor can detect the concentration of surrounding smoke and convert it into a voltage signal, which is then sent to the signal processing module 12 via the first switch 11. The signal processing module 12 can amplify and compare the smoke voltage signal sent by the smoke detection module 17, and send the comparison result to the central control module 16. The comparison result can be 0 or 1. The central control module 16 is configured to receive a 1 and control the alarm module 18 to sound an alarm.

[0047] The self-test module 10 has a built-in timing device. When the preset time is reached, the self-test module 10 sends a timing signal to the switch control module 13. At this time, the switch control module 13 controls the first switch 11 to connect the self-test module 10 and the signal processing module 12, and controls the second switch 14 to connect the signal processing module 12 and the self-test alarm module 15. Simultaneously, the self-test module 10 sends a self-test signal to the signal processing module 12. The level of the self-test signal is consistent with the level of the output of the smoke detection module 17 when it detects smoke. For example, if the smoke detection module 17 outputs a high-level signal when it detects smoke, the self-test module 10 should also send a high-level signal during self-test to simulate the signal output when smoke is detected. The self-test module 10 sends the self-test signal to the signal processing module 12. After the same amplification and comparison processing, the comparison result is sent to the self-test alarm module 15. The self-test alarm module 15 has a built-in timing device. If it does not receive a 1 within the preset time, it will trigger an alarm, indicating that the signal processing module 12 may be damaged and unable to provide an effective alarm, thus achieving the purpose and effect of self-test.

[0048] As can be seen from the above, this disclosure, through automated signal processing and switch control, can monitor the safety status within a building in real time and automatically trigger an alarm mechanism when an abnormality is detected, without the need for manual intervention, thereby improving the timeliness and accuracy of early warning. This disclosure includes a self-testing module 10, which can periodically perform self-tests on the signal processing module 12 of the system, ensuring that the system is always in good working order. In the event of a fault or abnormality, it can promptly trigger an alarm, improving the reliability and stability of building safety early warning.

[0049] Figure 2 This is a schematic diagram of the structure of the second type of building safety early warning system provided in this embodiment. Figure 3 This is a circuit schematic diagram of a signal processing module provided in an embodiment of this disclosure. (Refer to...) Figure 2 and Figure 3 In one embodiment of this disclosure, the signal processing module 12 includes: a first amplification unit 121, a second amplification unit 122, and a comparison unit 123;

[0050] The input terminal of the first amplification unit 121 is the input terminal of the signal processing module 12, and the smoke detection module 17 is connected to the input terminal of the first amplification unit 121 through the first switch 11.

[0051] The output terminal of the first amplification unit 121 is connected to the input terminal of the second amplification unit 122;

[0052] The output of the second amplification unit 122 is connected to the inverting input of the comparison unit 123. The non-inverting input of the comparison unit 123 is configured to receive the smoke reference signal. The output of the comparison unit 123 is connected to the stationary input of the second switch 14.

[0053] In this embodiment, the first amplification unit 121 includes: resistors R1, R2, R4, and R5, capacitors C1, C2, C3, and C4, and operational amplifier U1.

[0054] The first end of resistor R1 is connected to the power supply, and the second end of resistor R1 is grounded through capacitor C1. The first end of resistor R2 is connected to the stationary end of the first switch 11, and the second end of resistor R2 is grounded.

[0055] The non-inverting input of operational amplifier U1 is connected to the stationary terminal of the first switch 11. The inverting input of operational amplifier U1 is connected to the positive terminal of capacitor C3 through resistor R4. The output of operational amplifier U1 is connected to the inverting input of operational amplifier U1 through resistor R5. The output of operational amplifier U1 is connected to the inverting input of operational amplifier U1 through capacitor C2. The negative terminal of capacitor C3 is grounded. The output of operational amplifier U1 is connected to the negative terminal of capacitor C4. The positive terminal of capacitor C4 is connected to the input of the second amplification unit 122.

[0056] The second amplification unit 122 includes: resistors R6, R7, R8, and R9, capacitor C5, and operational amplifier U2;

[0057] The first end of resistor R6 is the input terminal of the second amplification unit 122, and the second end of resistor R6 is connected to the non-inverting input terminal of operational amplifier U2. The inverting input terminal of operational amplifier U2 is connected to the power supply.

[0058] The first end of resistor R7 is connected to the inverting input of operational amplifier U2, and the second end of resistor R7 is grounded.

[0059] The output terminal of operational amplifier U2 is connected to the inverting input terminal of operational amplifier U2 through resistor R8, the output terminal of operational amplifier U2 is connected to the inverting input terminal of operational amplifier U2 through capacitor C5, and the output terminal of operational amplifier U2 is connected to the non-inverting input terminal of comparator unit 123 through resistor R9.

[0060] Comparison unit 123 includes: resistor R10, resistor R11 and operational amplifier U3;

[0061] The non-inverting input of operational amplifier U3 is the same as the non-inverting input of comparator unit 123. The first end of resistor R10 is connected to the power supply, and the second end of resistor R10 is grounded through resistor R11. The inverting input of operational amplifier U3 is connected to the second end of resistor R10, and the inverting input of operational amplifier U3 is the same as the inverting input of comparator unit 123.

[0062] In this embodiment, resistor R1 and capacitor C1 filter the power supply, resistor R2 reduces signal drift, making the smoke voltage signal at the non-inverting input of operational amplifier U1 more stable. The amplification gain of operational amplifier U1 can be adjusted by adjusting resistors R4 and R5. Capacitors C2 and C5 are configured for phase lead compensation. Capacitor C4 couples the signal output from operational amplifier U1 and sends it to the non-inverting input of operational amplifier U2 via resistor R6. Operational amplifier U2 is a non-inverting proportional amplifier, and its amplification gain can be adjusted by adjusting resistors R7 and R8. The smoke voltage signal after two stages of amplification is sent to the non-inverting input of operational amplifier U3. Operational amplifier U3 compares the voltage signal received at its non-inverting input with a smoke reference signal. The smoke reference signal can be adjusted by adjusting resistors R10 and R11. If the voltage signal received at the non-inverting input of operational amplifier U3 is greater than the smoke reference signal, the output is 1; if the voltage signal received at the non-inverting input of operational amplifier U3 is less than the smoke reference signal, the output is 0.

[0063] The output of the comparison unit 123 can be sent to the central control module 16 via the second switch 14, or it can be sent to the self-test alarm module 15 via the second switch 14, depending on the connection status of the second switch 14.

[0064] As can be seen from the above, this disclosure achieves precise amplification of the output signal of the smoke detection module 17 through the first amplification unit 121 and the second amplification unit 122, thereby improving the signal sensitivity and ensuring the stability and accuracy of the signal during transmission. Capacitors C2 and C5 improve the phase characteristics of the signal, reducing errors caused by phase distortion.

[0065] Figure 2 This is a schematic diagram of the structure of the second type of building safety early warning system provided in this embodiment. (Refer to...) Figure 2 In one embodiment of this disclosure, the self-test module 10 includes: a first timer 101, a first self-test control unit 102, and a signal generator 103;

[0066] The output of the first timer 101 is connected to the first signal input of the first self-test control unit 102, and the first signal output of the first self-test control unit 102 is connected to the control terminal of the signal generator 103.

[0067] The output terminal of the signal generator 103 is the first output terminal of the self-test module 10, and the second signal output terminal of the first self-test control unit 102 is the second output terminal of the self-test module 10.

[0068] In one embodiment of this disclosure, the self-test alarm module 15 includes: a second timer 151, a second self-test control unit 152, a light-emitting diode 153, and a communication unit 154;

[0069] The first moving end of the second switch 14 is connected to the first signal input terminal of the second self-test control unit 152, and the output terminal of the second timer 151 is connected to the second signal input terminal of the second self-test control unit 152.

[0070] The first signal output terminal of the second self-test control unit 152 is used to control the operation of the light-emitting diode 153, and the second signal output terminal of the second self-test control unit 152 is used to control the operation of the communication unit 154.

[0071] In this embodiment, the smoke detection module 17 can be a smoke sensor, which generates a high-level signal when it detects smoke.

[0072] When the first timer 101 reaches the preset time, it sends a timing signal to the first self-test control unit 102 and the switch control module 13. The switch control module 13 controls the first switch 11 to connect the self-test module 10 and the signal processing module 12, and controls the second switch 14 to connect the signal processing module 12 and the self-test alarm module 15. At this time, the first self-test control unit 102 controls the signal generator 103 to send a high-level signal to simulate the output signal when the smoke sensor detects smoke.

[0073] When the second self-test control unit 152 does not receive 1 within the preset time of the second timer 151, the second self-test control unit 152 controls the light-emitting diode 153 to light up and controls the communication unit 154 to send an abnormal signal to the terminal device. The terminal device can be a mobile phone, computer, etc. Relevant personnel can use their mobile phones to check which building's signal processing module 12 is abnormal, which is convenient for relevant personnel to check.

[0074] It should be noted that the preset time of the second timer 151 can be slightly longer than the preset time of the first timer 101 to allow sufficient time for signal processing. When the second self-test control unit 152 receives a 1, it controls the second timer 151 to reset and restart the timing. After receiving the timing signal from the first timer 101 and performing its action, the switch control module 13, after a preset time (e.g., 5 seconds), controls the first switch 11 and the second switch 14 to reset and return to their initial state. This can be achieved through the timer built into the switch control module 13.

[0075] As can be seen from the above, this disclosure, through the coordinated operation of the first timer 101, the first self-test control unit 102, and the signal generator 103, achieves periodic self-testing of the signal processing module 12, ensuring that this disclosure can simulate the normal working state of a smoke sensor without external smoke stimulation, thereby verifying the response capability and signal transmission path integrity of this disclosure. In this disclosure, when the second self-test control unit 152 fails to receive the expected signal within a preset time, it immediately triggers an alarm mechanism, providing a local visual alarm through the light-emitting diode 153 and sending an abnormal signal to a remote terminal device through the communication unit 154, realizing immediate fault detection and remote notification, and improving the stability and reliability of building safety early warning.

Water leakage sensor 21 can be a raindrop sensor and can be installed at the connection of critical pipes in the building.

[0086] The temperature signal detected by the temperature sensor 19 is sent to the temperature comparator 20. The temperature comparator 20 compares the received temperature information with the temperature reference signal Verf1. When the detected temperature signal is greater than the temperature reference signal Verf1, the temperature comparator 20 sends 1 to the central control module 16. When the detected temperature signal is less than the temperature reference signal Verf1, the temperature comparator 20 sends 0 to the central control module 16.

[0087] The leakage signal detected by the leakage sensor 21 is sent to the leakage comparator 22. The leakage comparator 22 compares the received leakage information with the leakage reference signal Vref2. When the detected leakage signal is greater than the leakage reference signal Vref2, the leakage comparator 22 sends 1 to the central control module 16. When the detected leakage signal is less than the leakage reference signal Vref2, the leakage comparator 22 sends 0 to the central control module 16.

[0088] When the central control module 16 receives a signal, the control indicator 181 lights up and the buzzer 182 sounds, alerting residents that a fire may have occurred and urging them to evacuate immediately.

[0089] Storage module 23 can store information received by central control module 16, such as normal environmental time periods and alarm counts.

[0090] As can be seen from the above, this disclosure, through temperature sensor 19 and temperature comparator 20, can monitor the temperature information inside the building in real time and compare it with the preset temperature reference signal Verf1, thus promptly detecting potential fire risks. This disclosure, through water leakage sensor 21 and water leakage comparator 22, enables the monitoring of humidity information inside the building, helping to prevent water damage accidents and electrical short circuits caused by water leakage. This disclosure, through storage module 23, records and stores the information received by the central control module 16, which is helpful for subsequent accident analysis and accountability tracing, and also provides data support for building safety management.
