Description

Technical Field

[0001] This utility model relates to the field of door control technology, and in particular to an automatic earthquake emergency door. Background Technology

[0002] An earthquake, also known as a seismic event or ground vibration, is a rapid rupture within the Earth's interior that generates seismic waves. It is a common natural phenomenon on Earth. Seismic waves are produced by the rapid vibration of the Earth's surface caused by crustal movement, which releases energy rapidly within the crust.

[0003] Because earthquakes are highly destructive to buildings, it is crucial to open doors quickly during an earthquake. A strong tremor can deform and tilt door frames, making doors impossible to open and obstructing escape routes, significantly hindering escape. However, due to the short escape time during an earthquake, it is difficult for escaping individuals to manually open doors quickly enough in the split second of an earthquake. Utility Model Content

[0032] Figure 1 This is a schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0033] To make the technical problems, solutions, and advantages of this utility model clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device and / or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] like Figure 1 As shown, an embodiment of this utility model provides an automatic earthquake emergency door, including a door body, and further comprising:

[0036] Digital vibration sensor, digital control unit, actuator unit, button unit, Bluetooth communication unit;

[0037] The digital vibration sensor, digital control unit, execution unit, and Bluetooth communication unit are all located inside the door body, while the button unit is installed on the door body;

[0038] The output terminals of the digital vibration sensor and the button unit are connected to the input terminal of the digital control unit;

[0039] The digital control unit connects to the earthquake early warning platform via a Bluetooth communication unit;

[0040] The output of the digital control unit is connected to the control terminal of the execution unit.

[0041] The working principle of this utility model embodiment is as follows:

[0042] The digital vibration sensor sends the acquired vibration signal to the digital control unit. The earthquake early warning platform sends the earthquake intensity signal of the door's location to the digital control unit via the Bluetooth communication unit. The digital control unit sends a control command to the execution unit based on the vibration signal or earthquake intensity signal to control the door to be in the open state. The button unit sends an unlock signal to the digital control unit. The digital control unit sends a control command to the execution unit based on the unlock signal to control the door to be in the open state.

[0043] In this embodiment of the utility model, the digital vibration sensor is model YD280, the digital control unit adopts STM32 series microcontroller, and the earthquake early warning platform is a platform that provides earthquake early warning before an earthquake occurs through a dense earthquake monitoring and early warning network, similar to an urban earthquake early warning system.

[0044] It should be noted that issuing corresponding control commands based on the input signals is a function inherent in the STM32 series microcontroller controller itself. This embodiment of the invention does not involve any improvement to its internal data processing process. Therefore, the specific process of processing vibration signals and / or earthquake intensity signals and unlocking signals to obtain control commands will not be described in detail.

[0045] In this embodiment of the invention, the Bluetooth communication unit includes a Bluetooth signal transmitter and a Bluetooth signal receiver. The Bluetooth signal transmitter receives earthquake intensity signals about its location from the earthquake early warning platform via the network and transmits the earthquake intensity signals to the digital control unit via the Bluetooth signal receiver.

[0046] In this embodiment of the invention, the Bluetooth signal transmitting device is an ESP8266 chip integrated on the STM32 series microcontroller, while the Bluetooth signal receiving device uses a Bluetooth serial port module of model DF-BluetoothV3. The ESP8266 chip interacts with the Bluetooth serial port of DF-BluetoothV3 through serial communication to realize the transmission of earthquake intensity signals.

[0047] The earthquake emergency automatic door provided in this embodiment can be widely used in densely populated residential areas and student dormitories in earthquake-prone areas.

[0048] In this embodiment of the invention, the signal emitted by the earthquake early warning platform is a photoelectric signal, while the vibration signal is transmitted via infrasound. At the epicenter, the signal emitted by the earthquake early warning platform is first processed and analyzed (to prevent false alarms), and often cannot appear immediately. In this case, a digital vibration sensor is used to trigger the door to open. In areas outside the epicenter, the signal emitted by the earthquake early warning platform is transmitted at the speed of light after processing, and thus arrives faster than the seismic waves. In this case, a Bluetooth communication unit is used to transmit the signal emitted by the earthquake early warning platform to open the door immediately. The combined use of these two methods ensures that the door can be opened as quickly as possible regardless of location.

[0049] In this embodiment of the utility model, the execution unit includes a motor, a transmission nut, a screw, an infrared sensor, and an ultrasonic sensor;

[0050] The motor is installed on the lintel, and the infrared sensor and ultrasonic sensor are located on both sides of the door body to detect whether there are obstacles in the door opening and closing area, thus preventing pinching.

[0051] The motor drives the transmission shaft to rotate, which in turn drives the transmission nut to move. The door body is connected to the transmission nut via the door frame, which drives the door body to open and close. The screw is used to hold the transmission nut in place, so that the door body remains locked until an opening command is received.

[0052] Preferably, it also includes an I / O expansion interface board for providing I / O expansion interfaces;

[0053] The IO expansion interface board is located inside the door body;

[0054] The output terminals of the digital vibration sensor, the button unit, and the control terminal of the actuator are all connected to the IO expansion interface board via wires.

[0055] The digital control unit and Bluetooth communication unit are both plugged into the IO expansion interface board.

[0056] In this embodiment of the utility model, the IO expansion interface board adopts a sensor expansion board with dual-channel motor drive. The sensor expansion board is equipped with VCC and GND ports for each pin, which facilitates the connection of the sensor. It also reserves rich interface resources such as IIC interface, serial port, and Xbee slot, which can more easily connect external devices.

[0057] Specifically, it also includes a power supply unit that powers the digital control unit and the execution unit;

[0058] The input terminal of the power supply unit is connected to the mains power terminal;

[0059] The output terminal of the power supply unit is connected to the power supply terminal of the digital control unit and the power supply terminal of the execution unit, respectively.

[0060] In this embodiment of the utility model, the power supply unit consists of a conventional step-down circuit, a conversion circuit, a voltage regulator, and a protection circuit. This embodiment of the utility model does not involve any improvement to the specific circuit structure, so their connection relationships will not be described in detail.

[0061] Preferably, it also includes a first light-emitting unit and a second light-emitting unit for providing visual cues;

[0062] The first light-emitting unit and the second light-emitting unit are respectively disposed on the inner and outer sides of the door body;

[0063] The input terminals of the first and second light-emitting units are both connected to the output terminal of the digital control unit via an IO expansion interface board.

[0064] In this embodiment of the invention, the first light-emitting unit and the second light-emitting unit are alarm lights and are normally off. When the earthquake intensity signal received by the digital control unit is greater than the preset threshold or vibration signal, the digital control unit controls the first light-emitting unit and the second light-emitting unit to light up and flash, visually reminding the user to evacuate the residence as soon as possible.

[0065] Ideally, it also includes an alarm unit for providing auditory alerts;

[0066] The alarm unit is connected to the output of the digital control unit via an I / O expansion interface board.

[0067] Ideally, the alarm unit consists of two speakers, one on the inside and one on the outside of the door. When the earthquake intensity signal received by the digital control unit exceeds a preset threshold or vibration signal, the digital control unit controls the speakers to emit an alarm sound, audibly reminding the user to evacuate the residence as soon as possible.

[0068] In this embodiment of the utility model, the preset threshold is 6. When the earthquake intensity signal is greater than or equal to 6, the digital control unit controls the speaker to emit an alarm sound. In the field of earthquake early warning, an earthquake intensity signal greater than or equal to 6 indicates that the earthquake will cause varying degrees of damage to buildings.

[0069] Specifically, the button unit includes a first button and a second button;

[0070] The first button is located on the outside of the door body and is used to open the door from the outside. The second button is located on the inside of the door body and is used to open the door from the inside.

[0071] The output terminals of both the first and second buttons are connected to the input terminals of the digital control unit via an IO expansion interface board.

[0072] Preferably, the first button is a button with authentication function, such as a button with fingerprint recognition function or a button with facial recognition function. When using a button with fingerprint recognition function, the SKU:SEN0359 fingerprint recognition unit can be used as the button. This recognition unit has fingerprint verification functions such as fingerprint enrollment, fingerprint deletion, and fingerprint comparison, and can play the role of allowing only authorized personnel to pass.

[0073] It should be noted that verifying identity through biometric methods (such as fingerprint recognition or facial recognition) is a conventional technical means in this field. The embodiments of this utility model do not involve any improvement to the recognition process, so the recognition process will not be described in detail in this utility model.

[0074] Based on the structure provided above, the embodiments of this utility model operate in three situations, and the working process is as follows:

[0075] Under normal circumstances:

[0076] The user presses the first or second button from outside or inside the door. The first or second button sends an unlock signal to the digital control unit through the IO expansion interface board. The digital control unit sends a control command to the execution unit through the IO expansion interface board according to the unlock signal to control the door body to open.

[0077] When an earthquake occurs but the epicenter is not located:

[0078] The Bluetooth signal transmitter receives the earthquake intensity signal of the door's location from the earthquake early warning platform via the network, and sends the earthquake intensity signal to the digital control unit via the Bluetooth signal receiver and the IO expansion interface board. The digital control unit sends control commands to the execution unit through the IO expansion interface board according to the earthquake intensity signal to control the door to open, control the first and second light-emitting units to light up and flash, and control the two speakers to emit an alarm sound to remind the user to evacuate the residence as soon as possible.

[0079] In the event of an earthquake and being located at the epicenter:

[0080] The Bluetooth signal transmitter receives the earthquake intensity signal of the door's location from the earthquake early warning platform via the network, and sends the earthquake intensity signal to the digital control unit via the Bluetooth signal receiver and IO expansion interface board. The digital vibration sensor sends the received vibration signal to the digital control unit via the IO expansion interface board. The digital control unit sends control commands to the execution unit via the IO expansion interface board based on the earthquake intensity signal and / or vibration signal to control the door to open, control the first and second light-emitting units to light up and flash, and control the two speakers to emit an alarm sound to remind the user to evacuate the residence as soon as possible.

[0081] In summary, when the digital vibration sensor detects a large vibration signal or receives an earthquake intensity signal greater than or equal to a preset threshold, the door body can be opened immediately during an earthquake, giving people more time to escape. At the same time, the alarm sound and flashing lights remind people to evacuate safely as soon as possible.

[0082] This embodiment of the invention utilizes a digital vibration sensor to send acquired vibration signals to a digital control unit. An earthquake early warning platform sends an earthquake intensity signal indicating the door's location to the digital control unit via a Bluetooth communication unit. The digital control unit then sends control commands to the execution unit based on the vibration and / or earthquake intensity signals to keep the door open. A button unit sends an unlock signal to the digital control unit, which in turn sends control commands to the execution unit to keep the door open. Compared to existing technologies, this embodiment allows for door opening via a button in normal use. In the event of an earthquake, the digital control unit controls the execution unit to execute the door opening command based on the earthquake intensity and / or vibration signals sent by the earthquake early warning platform and the digital vibration sensor, automatically opening the door immediately and providing more time for people to escape.

[0083] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
