Description

Technical Field

[0001] The utility model relates to the technical field of alarm and escape, in particular to an emergency alarm linkage unlocking device. Background Art

[0002] At present, with the improvement of public safety awareness, the application of emergency alarm and linkage unlocking technology in various public places is becoming more and more extensive, especially in crowded places with high requirements for personal safety but relatively low requirements for property safety, such as schools, nursing homes, hospitals, etc. However, the existing emergency alarm and unlocking systems have many technical deficiencies in case of emergencies: First of all, most traditional door lock systems are manually operated or rely on external power supply control. When emergencies such as fires and earthquakes occur, it is difficult to respond in a timely manner, lacking an intelligent emergency linkage mechanism and unable to automatically unlock the door lock, thus hindering the rapid evacuation of personnel. Secondly, the delay or absence of alarm signals is a common problem. Existing systems often cannot be linked with the alarm system, especially when the power supply is interrupted, it is more difficult to send effective alarm signals, resulting in the failure to send out alarms to the outside in time after an accident, delaying the opportunity for emergency disposal and increasing risks and losses.

[0003] In addition, most existing door locks and alarm systems are highly dependent on electricity and are prone to failure when the power is cut off or the circuit is damaged, seriously affecting the emergency evacuation efficiency. Moreover, the current door lock systems are usually independent mechanical devices or simple electronic control systems, lacking automation and intelligence capabilities and unable to respond promptly to environmental changes such as fire smoke and gas leakage. Finally, some existing solutions are complex in design, high in cost, and difficult to maintain. In crowded and frequently used places, complex devices not only increase the maintenance cost but may also affect normal use due to improper maintenance, reducing the overall safety. Summary of the Utility Model

[0004] The problem to be solved by the utility model is that when an emergency occurs in a public place, due to the power failure of the external power supply system, it is impossible to send an alarm signal to the accident in time and unlock the door lock at the same time, hindering the emergency evacuation.

[0005] To solve the above technical problems, the technical scheme adopted by the utility model is as follows: An emergency alarm linkage unlocking device, including a wireless remote control switch, an industrial sound and light alarm, an electromagnetic lock and an external power supply system, characterized in that:

[0006] The wireless remote control switch includes a wireless signal generator and a built-in battery, and is used for transmitting a wireless alarm signal;

[0007] The industrial sound and light alarm includes an integrated circuit, a wireless signal receiver and a built-in battery that are signal-connected to the integrated circuit. The wireless signal receiver is used for receiving the wireless alarm signal, sending out an alarm message and controlling the electromagnetic lock;

[0008] The electromagnetic lock is electrically connected to the built-in battery of the industrial sound and light alarm and is used to control the locking of the door lock;

[0009] The external power supply system is electrically connected to the industrial sound and light alarm and is used to supply power to the industrial sound and light alarm and charge the built-in battery of the industrial sound and light alarm;

[0010] The wireless remote control switch is signal-connected to the industrial sound and light alarm through a wireless signal generator and a wireless signal receiver to realize two-way signal transmission.

[0011] Further, the communication distance of the wireless remote control switch is 0 to 30 m, and the signal transmission frequency of the wireless remote control switch is consistent with the signal reception frequency of the industrial sound and light alarm within the communication distance, which is used for wireless data transmission with at least two industrial sound and light alarms within the communication range.

[0012] Further, the integrated circuit of the industrial sound and light alarm includes an alarm light and a speaker. When the wireless signal receiver receives a wireless alarm signal, the alarm light flashes and the speaker emits an alarm.

[0013] Further, the built-in battery of the industrial sound and light alarm is a 12V battery, which is used to continue to provide power to maintain the normal operation of the industrial sound and light alarm when the external power supply system is interrupted.

[0014] Further, the working voltage of the electromagnetic lock is 12V. When the industrial sound and light alarm receives a wireless alarm signal, the current output by the built-in battery of the industrial sound and light alarm is used to drive the electromagnetic lock to unlock by energization.

[0015] Further, an emergency alarm linkage unlocking device provided by the present utility model further includes a reset mechanism. The reset mechanism includes a reset key, and the wireless remote control switch is reset by the reset key, which is used to stop the alarm work of the device.

[0016] The reset key has the following functions:

[0017] (1) Stop the device from working: After the emergency event ends, the alarm and the electromagnetic lock can be manually stopped by the reset key, so that the system returns to a static state.

[0018] (2) Restore the initial state of the system: The reset key can reset the device to the initial state, enabling it to start and operate normally when the next emergency occurs.

[0019] (3) Manual control: The reset key provides the possibility of manual operation, enabling the user to manually turn off the device in specific situations (such as false alarms or after testing) without relying on the automated system.

[0020] The reset key is a universal key and can be configured according to the reset hole of the wireless remote control switch.

[0021] The beneficial effects of the present utility model are as follows: By integrating a storage battery, an autonomous alarm system, and a door lock linkage device, the deficiencies of the traditional system are effectively solved. When there is a power outage or other emergencies, an alarm signal can be automatically sent out and the door lock can be linked to open, providing a clear evacuation passage for personnel and ensuring the efficiency and safety of emergency evacuation. Its structure is simple and reliable, easy to maintain, and can significantly improve the emergency response and handling capabilities in emergencies. This design not only improves the safety of public places but also provides more effective technical guarantees for dealing with emergencies. Brief Description of the Drawings

[0023] For those skilled in the art to better understand the content of the present utility model, make the purpose, technical solution, and advantages of the present utility model clearer, the following further detailed description of the present utility model is provided in conjunction with the embodiments and the drawings. The illustrative embodiments of the present utility model and their descriptions are only used to explain the present utility model and do not further limit the present utility model.

[0024] The present utility model is used to solve the problem that when an emergency occurs in a public place, due to the power outage of the external power supply system, the door lock cannot be automatically released, hindering the rapid evacuation of personnel, it is difficult to send out an effective alarm signal, resulting in the failure to send out an alarm externally in a timely manner after an accident, delaying the opportunity for emergency handling, and increasing risks and losses.

[0025] As Figure 1 shown, this embodiment provides an emergency alarm linkage unlocking device, including a wireless remote control switch 1, an industrial sound and light alarm 2, an electromagnetic lock 3, and an external power supply system 4 that are signal-connected;

[0026] The wireless remote control switch 1 includes a wireless signal transmitter and a built-in storage battery, and is used to transmit a wireless alarm signal. The built-in storage battery of the wire remote control switch 1 is a 9V alkaline battery;

[0027] The wireless remote control switch 1 adopts an NRF24L01 wireless transmitting and receiving module. NRF24L01 is a low-power, high-performance wireless transmitting and receiving module, suitable for battery-powered devices. Its transmission distance can reach 100 meters, supports a transmission rate of up to 2Mbps, ensuring fast and stable data transmission. In addition, this module has good anti-interference ability and is suitable for complex electromagnetic environments to ensure the reliability of signal transmission.

[0028] The industrial audible and visual alarm 2 includes an integrated circuit, a wireless signal receiver and a built-in battery that are signal-connected to the integrated circuit. The wireless signal receiver is used to receive wireless alarm signals, send out alarm information and control the electromagnetic lock 3. The built-in battery of the industrial audible and visual alarm 2 is a 12V battery;

[0029] The industrial audible and visual alarm 2 adopts the HZBJ-19 type industrial audible and visual alarm. The HZBJ-19 type industrial audible and visual alarm can quickly attract attention in a noisy environment with its high-decibel alarm and high-brightness lights, ensuring safe production. It supports multiple voltage selections to adapt to different power supply requirements. At the same time, it adopts a low-power consumption design to save energy and reduce operating costs. The alarm has high durability, and its protection level reaches IP65, capable of waterproof, dustproof and shockproof, suitable for harsh industrial environments. In addition, it can work normally within a wide range of operating temperatures, adapting to different climate conditions. Its characteristics of easy installation and maintenance, as well as strong anti-interference ability, reduce the false alarm rate and maintenance costs. The HZBJ-19 type alarm is applicable to various places that require high-reliability alarms such as mechanical equipment, production lines, chemical plants, mines, power facilities, etc., and is also applicable to crowded public places such as schools, hospitals, and nursing homes.

[0030] The electromagnetic lock 3 is electrically connected to the independent power supply unit of the industrial audible and visual alarm 2 and is used to control the locking of the door lock.

[0031] The electromagnetic lock 3 adopts the YM-280 electromagnetic lock. The YM-280 is an electromagnetic lock with a locking force of 280 kg, with strong security to ensure that the door lock is not easily damaged in an emergency. It adopts a 12V low-power consumption design, which is very suitable for use with a battery, energy-saving and efficient. In addition, the electromagnetic lock has a power-off unlocking function and can automatically unlock when the power is cut off to ensure the safe evacuation of personnel.

[0032] The external power supply system 4 provides a 220V working voltage to maintain the normal operation of the entire system.

[0033] Further, the communication distance of the wireless remote control switch 1 is 0 to 30 m, and the signal transmission frequency of the wireless remote control switch 1 is the same as the signal reception frequency of the industrial audible and visual alarm 2, and is used for wireless data transmission with at least 2 industrial audible and visual alarms 2 within the communication range.

[0034] Further, the integrated circuit of the industrial audible and visual alarm 2 includes an alarm light and a speaker. When the wireless signal receiver receives a wireless alarm signal, the alarm light flashes and the speaker emits an alarm.

[0035] Further, the industrial audible and visual alarm 2 includes a 12V battery, which is used to continue to provide power to maintain the normal operation of the industrial audible and visual alarm 2 when the external power supply system is interrupted.

[0036] Furthermore, the working voltage of the electromagnetic lock 3 is 12V. When the industrial sound and light alarm 2 receives the wireless alarm signal, the 12V battery outputs 12V DC power to drive the electromagnetic lock 3 to power on and unlock.

[0037] Furthermore, it also includes a reset mechanism, which resets the wireless remote control switch by a reset key to stop the operation of the device.

[0038] Furthermore, the specific component information of the wireless remote control switch 1, the industrial sound and light alarm 2 and the electromagnetic lock 3 is shown in Table 1:

[0039] Table 1 Component list

[0040]

[0041] When an emergency occurs, the wireless remote control switch 1 is pressed to send out an alarm signal. Since the wireless remote control switch 1 has a built-in battery, the device can also send out a signal in the event of a power outage caused by an emergency.

[0042] After receiving the alarm signal sent by the wireless remote control switch 1, the wireless signal receiving device in all the industrial sound and light alarms 2 within the communication range of the wireless remote control switch 1 starts to work, the alarm light flashes, the speaker sounds an alarm, and at the same time closes the power supply circuit connected to the electromagnetic lock 3, the electromagnetic lock 3 is powered on and retracted, and the door lock is opened. Since this industrial sound and light alarm 2 has a built-in 12V battery, when a power outage is caused by an unexpected accident, the external power supply system 4 is powered off and cannot normally provide the normal working voltage of the industrial sound and light alarm 2 described in the utility model. At this time, the built-in battery of the industrial sound and light alarm 2 intervenes to supply power and provides a 12V voltage to enable the industrial sound and light alarm 2 to work normally; if the external power supply system 4 does not have a power outage, the built-in battery of the industrial sound and light alarm 2 does not participate in the power supply.

[0043] Furthermore, when the accident is resolved, the wireless remote control switch 1 can be manually reset by using a reset key, and the entire device stops working.

[0044] After an emergency occurs, the device will send out an alarm signal through the wireless remote control switch 1 and control the electromagnetic lock to unlock. However, when the event ends or a false alarm occurs, the system is still in working condition. At this time, the wireless remote control switch 1 needs to be manually reset by the reset key to stop the transmission of the alarm signal. At the same time, the wireless signal receiving device in the industrial sound and light alarm 2 cannot receive the model sent by the wireless remote control switch 1, so the sound and light prompt of the alarm is stopped and the electromagnetic lock is relocked. This process ensures that the system can be restored to its initial state and ready to deal with the next emergency.

[0045] The reset key is a universal key and can be configured according to the reset hole of the wireless remote control switch 1.

[0046] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, 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, it should be considered as the scope recorded in this specification.

[0047] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
