Description
Technical Field
[0001] The present invention belongs to the fields of safety engineering and emergency evacuation. Background Art
[0002] As early as March 1, 2019, GB51309-2018 "Technical Standard for Fire Emergency Lighting and Evacuation Indication Systems" was officially implemented. The new national standard stipulates that intelligent centralized control emergency evacuation systems need to be installed in the following places: Places with a fire control room should choose a centralized control type system. Therefore, the country has a great demand for emergency evacuation facilities. However, most of the existing notice boards only have simple light guidance or sound guidance, without combining the two to achieve better guidance for the masses and unable to formulate evacuation routes in real time in the face of complex and changeable situations, which may affect or even mislead the evacuation of the crowd. Summary of the Invention
[0003] The purpose of the present invention is to provide route guidance for emergency evacuation personnel in real time in complex situations and guide them through the combination of sound and light. Aiming at the problem that no one has combined sound and light guidance, it can effectively improve the ability to evacuate the crowd and enhance the adaptability in complex situations.
[0004] In the improved solution, a positioning module, a power module, a sound guidance module, a light guidance module, a Bluetooth module, and an evacuation plan execution module are adopted.
[0005] In the improved solution, a guidance method combining area light and directional sound is adopted to cooperate with real-time path planning.
[0006] In the improved solution, the adaptability in various complex environments is enhanced.
[0007] The technical effects achieved by the present invention are as follows:
[0008] 1. It can evacuate the crowd through the guidance method combining sound and light.
[0009] 2. It can be linked with the mobile terminal to transmit evacuation data in real time.
[0010] 3. It has a system to detect environmental variables in real time. Brief Description of the Drawings

[0015] The present invention will be described in detail below with reference to the accompanying drawings.
[0016] The present invention and its implementation manners are described below. Such description is not restrictive, and the actual implementation manners are not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
[0017] Embodiment 1: As Figure 1 shown, this embodiment discloses various states of a sign, including charging, standby state, and state judgment of the passage.
[0018] The working mode of this embodiment is as follows: This embodiment discloses the daily operation of a sign, including: normally being in the standby situation and real-time detecting various environmental data of the passage. Once a disaster occurs, it judges whether this passage can pass normally by detecting the environmental data. If it is judged that it cannot pass, it will be transmitted to the emergency evacuation implementation module to regenerate a new emergency evacuation route. If the environmental data is normal, it will guide the crowd under the arrangement of the emergency evacuation implementation module; the purpose of this embodiment is to increase the accuracy of the sign in evacuating the crowd under complex and changeable disasters.
[0019] Embodiment 2: As Figure 2 , shown in FIG. 3, this embodiment discloses a directional sound output module of a sign with an STM32F sharp chip as the core. It includes STM32F series chips, a WIFI module, a Bluetooth module, a filtering circuit, a modulation power supply, and an ultrasonic amplification module
[0020] The working mode of this embodiment is as follows: This embodiment discloses a method for implementing directional sound of a sign, including: regulating the STM32F chip through digital audio, a power supply circuit, a Bluetooth module, a WIFI module, etc., and then the chip regulates a plurality of analog switches through an audio amplification circuit to enable the plurality of analog switches to output different ultrasounds, thereby achieving the effect of directional sound.
[0021] Embodiment 3: As Figure 4 shown, this embodiment discloses an overall module linkage mode of a sign, including: data driving, device execution, environmental data import, device control, evacuation plan judgment, evacuation plan execution, device linkage, evacuation plan execution, and sound and light linkage of a safety sign.
[0022] The working mode of this embodiment is as follows: Under normal circumstances, the positioning module will import environmental data into the device, and then the device control will change the device state. When the environment is normal, the detected data will drive the emergency evacuation execution module to formulate an evacuation plan. The formulation process is as follows: The environmental perception data is used by the module to generate the optimal evacuation path, and the plan is stored. By doing so, the sign guidance system can correctly evacuate people in case of emergencies; and in case of emergencies, when the device senses that an emergency has occurred, it will immediately activate the emergency plan guidance generator and the area light, achieving the sound and light mapping of the safety sign; among them, the emergency evacuation plan comes from the stored optimal path plan, but the specific emergency evacuation plan is changed in real time to prevent complex situations such as impassable roads in case of emergencies; at the same time, it will be linked with mobile devices to generate the evacuation route in the form of an animated picture in real time and upload it to the mobile terminal.
