Detailed Implementation

[0020] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0021] See Figure 1 , Figure 2 and Figure 3 This is a schematic diagram of the structure of this patent. A digital hotel alarm device includes a control box 1, an audible and visual alarm 2, an application layer 5, a sensing layer 6, and a ceiling 11. The control box 1 is equipped with a controller 3 and a transmission layer 4. The audible and visual alarm 2 is electrically connected to the controller 3.

[0022] The transmission layer 4 includes a wireless network module and a 4G communication module, which are wirelessly connected to the controller 3.

[0023] Application layer 5 includes the hotel security center monitoring platform and mobile APP, which are wirelessly connected to the wireless network module and 4G communication module.

[0024] The sensing layer 6 includes a smoke sensor, a temperature sensor, a door magnetic sensor, and a glass breakage sensor, all of which are electrically connected to the controller 3.

[0025] Controller 3 is the core component of the alarm device, responsible for receiving signals from sensors, processing alarm information, and controlling the operation of devices such as the audible and visual alarms and the communication module. An STM32 series microcontroller, such as the STM32F407, is selected. This microcontroller features high performance, low power consumption, and abundant peripheral resources, meeting the functional requirements of the alarm device. The controller connects to sensors, audible and visual alarms, and other devices via GPIO interfaces, and communicates with the communication module through serial ports, SPI, and I2C interfaces to achieve data acquisition, processing, and transmission.

[0026] The wireless network module selected is the ESP8266 Wi-Fi module. This module supports the 802.11 b / g / n protocol and has the advantages of low cost, low power consumption, and fast transmission speed. It can realize the connection between the alarm device and the hotel's internal wireless network and send alarm information to the hotel security center monitoring platform and the management personnel's mobile APP in real time.

[0027] The SIM800C 4G communication module is selected as a backup communication method. When the hotel's wireless network fails, the alarm device will send alarm information to the relevant emergency departments through the 4G communication module to ensure reliable transmission of alarm information.

[0028] Controller 3 and transmission layer 4 are housed within control box 1. Control box 1 is installed in the hotel's low-voltage electrical shaft or equipment room, in a well-ventilated, dry location free from strong electromagnetic interference, and is wall-mounted. The controller and sensors are connected via wired or wireless means to ensure stable signal transmission.

[0029] The Wi-Fi module and 4G communication module at transport layer 4 are installed near the controller to ensure a strong wireless signal. The Wi-Fi module is connected to the hotel's internal wireless network switch via a network cable, and the 4G communication module has a SIM card inserted and an antenna connected to ensure stable transmission of the communication signal.

[0030] The second type of audible and visual alarm uses a high-decibel audible and visual alarm, such as the HONEYWELL XTL-1000. This alarm features a 105dB high-decibel buzzer and bright LED flashing lights, which can attract people's attention in noisy environments. The alarm supports multiple alarm mode settings and can emit different audible and visual signals according to different alarm types and levels.

[0031] The sound and light alarm 2 is installed in a conspicuous location in various areas, such as corridors, stairwells, and lobbies, at a height of 2.5-3 meters above the ground to ensure that the alarm sound and light can cover the entire area.

[0032] The smoke sensor is a photoelectric smoke sensor, such as the Sharp GP2Y1010AU0F. This sensor has the characteristics of high sensitivity, fast response speed and strong anti-interference ability. It can accurately detect tiny smoke particles and is suitable for the complex environment of hotels.

[0033] The temperature sensor uses the DS18B20 digital temperature sensor, which has the advantages of high precision, single-bus communication, and no need for external components. It can communicate directly with the microcontroller to obtain ambient temperature data in real time.

[0034] The door magnetic sensor uses a wireless door magnetic sensor, such as the Aqara door and window sensor, which connects to the controller via wireless communication. It is easy to install and can monitor the opening and closing status of doors and windows in real time. When a door or window is opened, it immediately sends an alarm signal.

[0035] Door magnetic sensors are installed on the frame and moving parts of doors and windows respectively, ensuring that the two parts of the door magnetic sensor can fit tightly when the door or window is closed, and can detect the status change in time when the door or window is opened.

[0036] The glass breakage sensor uses a SECOM glass breakage detector, which employs dual vibration and sound detection technology to accurately identify the vibration and sound signals generated by glass breakage, effectively reducing the false alarm rate.

[0037] The glass breakage sensor is installed on the wall next to the glass door or window, 0.3-0.5 meters away from the glass, and 1.5-1.8 meters above the ground, to ensure that the sensor can effectively detect the vibration and sound generated by the glass breaking.

[0038] The smoke sensor and temperature sensor have a mesh body 7 at the bottom, and a mounting frame 8 is fixedly installed on the top of the mesh body 7. A connecting rod 9 is provided in the middle of the mounting frame 8, and a threaded rod 10 is installed at the top of the connecting rod 9. The ceiling 11 has a threaded groove 12 at the bottom, and the top of the threaded rod 10 is screwed into the threaded groove 12.

[0039] Specifically, the perception layer 6 also includes an infrared sensor and an emergency help button, both of which are electrically connected to the controller 3.

[0040] The infrared sensor selected is the HC-SR501 human infrared sensing module. This module adopts a dual-probe design, with a wide sensing range and high sensitivity, which can effectively detect human activity. It also has automatic delay shutdown and block time setting functions to prevent false alarms.

[0041] Infrared sensors are installed on the walls of entrances, windows, and areas where important items are stored, at a height of 1.8 to 2.2 meters above the ground. The angle of the sensor is adjusted to cover the area that needs to be monitored.

[0042] The emergency help button is a waterproof type, such as the LA68 series button, which is sturdy, durable, waterproof, dustproof, and prevents accidental activation. The button surface has clear markings to make it easy for guests and employees to find and use it quickly in an emergency.

[0043] Emergency help buttons are installed in prominent and easily accessible locations such as bedside tables in guest rooms, bathroom walls, and public areas, at a height of 1.2 to 1.5 meters from the ground.

[0044] Specifically, the connecting rod 9 includes a rotating rod 13 and a bearing 15. The top end of the rotating rod 13 is fixed to the bottom end of the threaded rod 10. A handle 14 is fixedly installed at the bottom end of the rotating rod 13. The inner side wall of the inner ring of the bearing 15 is fixedly installed on the side wall of the rotating rod 13. The middle part of the mesh body 7 is provided with a mounting hole, and the inner side wall of the mounting hole is fixed to the outer side wall of the outer ring of the bearing 15.

[0045] The bearing 15 is provided for relative rotation between the rotating rod 13 and the mesh body 7.

[0046] Specifically, positioning rods 16 are fixedly installed on both the left and right sides of the mounting frame 8, and a positioning groove 17 is provided at the bottom of the ceiling 11, with the top of the positioning rods 16 inserted into the positioning groove 17.

[0047] The top of the positioning rod 16 is inserted into the positioning groove 17 to define the installation position of the mounting frame 8 and the ceiling 11.

[0048] Specifically, the top height of the positioning rod 16 is higher than the top height of the threaded rod 10.

[0049] Since the top height of the positioning rod 16 is higher than the top height of the threaded rod 10, the positioning rod 16 can be inserted into the positioning groove 17 first to play a limiting role when the threaded rod 10 is not screwed into the threaded groove 12.

[0050] Specifically, the top of the mesh body 7 has a positioning ring 18 integrally formed.

[0051] like Figure 1 As shown, the positioning ring 18 is used to define the placement positions of the smoke sensor and temperature sensor relative to the mesh body 7.

[0052] Working Principle: Smoke and temperature sensors installed in various areas of the hotel continuously monitor environmental data in real time. When a smoke sensor (such as a Sharp GP2Y1010AU0F) detects that the smoke concentration in the environment exceeds a preset threshold, or a temperature sensor (such as a DS18B20) detects that the ambient temperature has risen sharply to the alarm temperature, the sensor transmits the detected analog signal (smoke sensor) or digital signal (temperature sensor) to the connected STM32F407 controller. For analog signals, the controller converts them into digital signals through its built-in A / D conversion module for subsequent processing.

[0053] After receiving abnormal data from the sensor, the controller filters and removes noise interference, then compares it with the preset fire alarm threshold to confirm a fire alarm event. At this point, the controller immediately sends a control signal to the local audible and visual alarm (such as a HONEYWELL XTL-1000) via the GPIO interface to activate the alarm. A high-decibel buzzer emits a sharp alarm sound, and bright LEDs flash rapidly to attract the attention of those nearby. Simultaneously, alarm display terminals in various areas of the hotel update in real time, clearly displaying the specific location and type of the fire alarm, allowing on-site personnel to quickly understand the situation and take initial response measures, such as evacuation and the use of fire extinguishers.

[0054] Upon activating the local alarm, the controller packages the fire alarm information, including details such as alarm time, alarm location (accurate to the specific room, floor, or area), and alarm type (fire). Subsequently, the controller transmits the alarm information in real-time to the hotel security center monitoring platform via the ESP8266 Wi-Fi module. If the hotel's wireless network fails, the controller automatically switches to the SIM800C 4G communication module, sending the alarm information to the hotel management's mobile app and the fire department, ensuring timely and accurate transmission of alarm information to relevant personnel. This facilitates rapid deployment of fire department rescue forces and prompt organization of internal emergency response by hotel management.

[0055] Infrared sensors (such as HC-SR501), door and window magnetic sensors (such as Aqara door and window sensors), and glass breakage sensors (such as SECOM glass breakage detectors) installed at hotel entrances, windows, and areas where valuables are stored are always operational. When an infrared sensor detects human infrared radiation and determines that an unauthorized person has entered the monitored area; or when a door and window magnetic sensor detects that a door or window has been opened under abnormal circumstances; or when a glass breakage sensor senses the vibration and sound signals generated by breaking glass, the corresponding sensor transmits the status data to the controller in the form of digital signals.

[0056] The controller receives and processes sensor data. Upon confirming an unauthorized intrusion, it activates a local audible and visual alarm, similar to a fire alarm, alerting nearby personnel through sound and light signals. Simultaneously, the intrusion alarm information is packaged and sent, according to a preset communication method, primarily via Wi-Fi to the hotel security center monitoring platform and the management personnel's mobile app. Because the intrusion alarm is a standard level alarm (compared to a fire alarm), its audible and visual alarm mode and notification method differ from those of a fire alarm; for example, the alarm sound frequency and light flashing rhythm are different, allowing hotel staff to quickly distinguish the alarm type. If the Wi-Fi network fails, a 4G communication module ensures successful alarm information transmission.

[0057] After receiving an unauthorized intrusion alarm, the hotel's security center monitoring platform quickly located the alarm location using the platform's electronic map, retrieved surveillance video of the area, and reviewed the situation. Based on the actual situation, security personnel immediately proceeded to the alarm area to inspect and handle the situation, such as removing the intruders and checking for damage to doors and windows. The results were recorded on the monitoring platform, and the alarm status was updated.

[0058] When hotel guests or staff encounter an emergency in their guest rooms, bathrooms, or public areas, pressing a waterproof emergency call button (such as the LA68 series button) will trigger an electrical signal that is directly transmitted to the controller, sending an emergency call alarm request to the system.

[0059] Upon receiving an emergency distress alarm signal, the controller activates a local audible and visual alarm and simultaneously packages the alarm information, sending it via Wi-Fi or 4G communication to the hotel security center monitoring platform and the management personnel's mobile app. Because the emergency distress alarm is a secondary alarm level, its audible and visual alarm mode falls between that of a fire alarm and an intrusion alarm, ensuring it receives sufficient attention while remaining easily distinguishable from other alarm types.

[0060] Upon receiving an emergency call, the hotel's security center and management quickly contact staff near the location to assess the situation and understand the specific needs and emergency circumstances of the person seeking help. For more serious emergencies, such as sudden illness or danger to a guest, while providing initial on-site assistance, they promptly contact external rescue forces, such as ambulances or police, and record the process and results in real time on the monitoring platform to ensure that the emergency is properly resolved.

[0061] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent.

However, those skilled in the art who understand the principle of the above patent can clearly understand the specifics of its power mechanism, power supply system and control system.

[0062] This patented technology places smoke and temperature sensors on a mesh body, which is equipped with an installation frame. The installation frame is fixed to the hotel ceiling by threaded rods. This connection eliminates the need for separate installation of the two sensors, shortening maintenance time and improving work efficiency. Furthermore, by installing door magnetic sensors and glass breakage sensors on the hotel doors and windows, timely detection of the doors and windows can be easily achieved, improving safety performance.
