Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting equipment, and in particular to an evacuation indicating device for automatic fire alarm. Background Art

[0002] With the acceleration of urbanization, high-rise buildings, large public buildings and complex industrial facilities are increasing. The evacuation of users of these buildings in emergency situations such as fire has become a major challenge. When a fire occurs, timely and accurate guidance of user evacuation is the key to ensuring life safety. It is necessary to ensure that users can evacuate to a safe area quickly and orderly when a fire occurs.

[0003] Traditional fire evacuation indication devices mainly rely on fixed signs and emergency lighting. These devices can provide basic evacuation guidance under normal circumstances. However, traditional methods have obvious shortcomings: fixed signs and emergency lighting are fixed in position, and these devices have low visibility in smoky environments. They cannot dynamically adjust the guidance direction according to the specific circumstances of the fire, which can easily cause users to become disoriented and make evacuation more difficult. Overall, the applicability and effectiveness of current evacuation methods in complex environments still need to be further optimized. Summary of the Invention

[0004] The purpose of the present invention is to provide an evacuation indication device for automatic fire alarm, which has the function of dynamically adjusting the guidance direction according to the specific situation of the fire. The user holds the evacuation indication mobile terminal in front of his eyes, effectively overcoming the problem of low visibility in a smoky environment and reducing the difficulty of evacuation.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: an evacuation indication device for automatic fire alarm, comprising a plurality of protective shells fixedly mounted on a wall, wherein a sensor module, a control box, an evacuation indication mobile terminal and an audible and visual alarm are arranged inside the protective shell;

[0006] The control box includes a central processing module, a GPS positioning module, a wireless transmission module, a battery power supply unit and a comparator module which are electrically connected to each other. The comparator module is used to compare the input signals of each sensor with the set threshold value. The GPS positioning module is used to determine the location of the fire.

[0007] The inner side wall of the protective shell is fixedly connected to a support plate, the upper surface of the support plate is provided with a groove, and the evacuation instruction mobile terminal is snapped into the inside of the groove, and each of the evacuation instruction mobile terminals receives instructions from the central processing module through wireless communication and displays corresponding evacuation instruction information;

[0008] The evacuation instruction mobile terminal includes a housing and a data receiving and processing module arranged inside the housing, wherein the data receiving and processing module includes a CPU control module, a wireless receiving module, a battery module, a display module, a storage module and a GPS / Beidou dual-mode positioning module electrically connected to each other, and the GPS / Beidou dual-mode positioning module is used to determine the user's location and display it through the display module;

[0009] The central processing module is electrically connected to the sound and light alarm, and the central processing module dynamically adjusts the display content of the evacuation instruction mobile terminal according to the data collected by the sensor module.

[0010] By adopting the above technical solution, the device achieves wide coverage of evacuation indication through multiple protective shells fixed on the wall, and the number and position of the protective shells can be determined according to different building structures. When in use, the sensor module, control box, evacuation indication mobile terminal and sound and light alarm are installed on the protective shell in sequence, the floor information is input into the storage module, and debugging is carried out to ensure the normal operation of each module, and the sensor threshold, alarm parameters and evacuation indication information are set. The sensor module continuously monitors the environmental parameters, the control box and the evacuation indication mobile terminal are in standby mode, and the evacuation indication mobile terminal displays conventional safety prompt information through the display module. The sensor module monitors the smoke concentration in the environment in real time and transmits the data to the central processing module in the control box. When the sensor module detects an abnormal change in the smoke concentration, the comparator module compares the sensor module input signal with the preset threshold, thereby improving the stability and reliability of the device and avoiding false alarms and missed alarms. If the threshold is exceeded, the sound and light alarm is triggered to sound an alarm, which prompts the user to the location of the protective shell and transmits the abnormal signal to the central processing module. The GPS positioning module determines the fire location. The central processing module dynamically adjusts the display content of the evacuation instruction mobile terminal based on the data collected by the sensor module. This dynamic adjustment mechanism can update the evacuation instruction information in real time according to the specific situation of the fire, ensuring that users receive the most accurate guidance during the evacuation process. In addition, the evacuation instruction mobile terminal is equipped with a GPS / Beidou dual-mode positioning module, which can accurately determine the user's location and display the optimal evacuation path in real time through the display module. The guidance direction is dynamically adjusted according to the specific situation of the fire. The central processing module transmits the evacuation instruction information to each evacuation instruction mobile terminal through the wireless transmission module. The user can pick up the evacuation instruction mobile terminal closest to him. During the evacuation process, the user holds the evacuation instruction mobile terminal in front of his eyes. After receiving the information, the evacuation instruction mobile terminal displays the corresponding evacuation instruction information through the display module, acting as a navigation function, guiding the user to evacuate quickly and safely, greatly improving evacuation efficiency and safety. In summary, this device combines a movable evacuation instruction mobile terminal with a fixed protective shell, dynamically adjusts the guidance direction according to the specific situation of the fire, and the user holds the evacuation instruction mobile terminal in front of his eyes, effectively overcoming the problem of low visibility in a smoky environment and reducing the difficulty of evacuation.

If there are many users and the vibration is obvious, the vibration signal will be fed back to the central processing module, which will analyze and process it to further optimize the evacuation route.
