Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of fire evacuation devices, and in particular to a wireless guidance and indication device and method for directional control of fire evacuation. Background Art
[0002] When a fire occurs, the safe and rapid evacuation of people is the top priority. In many building corridors, stairs and other locations, safety exit signs are installed to guide people to escape quickly in the event of a fire or other safety accident.
[0003] However, in some special circumstances when a fire or accident occurs, the path to the safety exit indicated by the safety exit sign may not be safe (for example, the safety exit has collapsed or the smoke density on the safety path is high). If the crowd directly follows the direction of the safety exit sign, it may delay precious escape time and may also cause secondary accidents such as congestion and trampling.
[0004] In response to the above problems, the existing method is to use intelligent guidance devices in buildings to collect real-time information from various locations in the building, conduct analysis and judgment, and then output the control of the crowd evacuation guidance direction device at each location to provide lighting direction guidance, thereby providing safe and fast guidance.
[0005] However, these approaches require the establishment of various power distribution and network infrastructures. In the event of a serious fire or accident, these infrastructures could be disrupted or even damaged, rendering intelligent safety guidance devices inoperable. Furthermore, some older buildings may not have the funds to equip these intelligent guidance devices and supporting systems.

Fixing screws are installed at the positions of the installation hole structures, and the fixing screws are installed at the positions of the fixing studs 104.
[0048] The rechargeable battery 2 is installed in the bottom area of the installation cavity 102. Correspondingly, a charging module is designed on the PCB board 301, and a charging port is opened on the main housing structure 101. This is very common in the prior art and will not be elaborated in the present invention. A front cover plate 4 is installed on the front side of the installation housing 1, and the front cover plate 4 is fixedly installed at the position of the front installation groove 103.
[0049] A hanging ring 105 is located on the upper side of the installation housing 1. The hanging ring 105 is provided with a hanging hole 106. An expansion screw 6 is installed on the wall. A part of the rod body of the expansion screw 6 protrudes from the wall. The hanging ring 105 of the guiding and indicating device M is hung on the expansion screw 6. A retaining ring 601 is provided at the side end of the expansion screw 6 protruding from the wall. Let the diameter dimension of the rod body of the expansion screw 6 be Da, let the diameter dimension of the retaining ring 601 be Dc, and let the width dimension of the hanging hole 106 be L. Then Da < Dc < L, that is, the retaining ring 601 can block the hanging ring 105.
[0050] Please refer to Figure 3 、 Figure 4 The main control board 3 includes a PCB board 301. The PCB board 301 is configured with an infrared sensing module 302, a safety direction indicating module 303, a sound sensing and acquisition module 304, a voice output module 305, and a Bluetooth module 306. The infrared sensing module 302 can monitor the human infrared signal. The safety direction indicating module 303 is used to indicate the safe escape direction. The sound sensing and acquisition module 304 can sense and monitor the surrounding sound sources and the decibel level. The voice output module 305 outputs voice. The Bluetooth module 306 can transmit and obtain information.
[0051] The front cover 4 includes a fixed plate 401 , which is provided with an infrared mounting hole 402 , a speaker mesh 403 , a voice speaker 404 installed inside the speaker mesh 403 , a rectangular transparent PVC 405 , and a sound collection hole 406 in sequence along the vertical direction.
[0052] The infrared mounting hole 402 is aligned with the infrared sensor module 302, the voice speaker 404 is electrically connected to the voice output module 305, the transparent PVC 405 is matched with the distribution range of multiple LED lamp beads 3031 of the safety direction indication module 303, and the sound collection hole 406 is aligned with the sound sensor collection module 304.
[0053] See also Figure 8 、 Figure 9 The safety direction indication module 303 area is configured with a first light group area D1, a second light group area D2, and a third light group area D3. The first light group area D1, the second light group area D2, and the third light group area D3 are all configured with multiple LED lamp beads 3031. The multiple LED lamp beads 3031 in the first light group area D1 and the third light group area D3 are arranged in an arrow pattern. The direction of the arrow formed by the multiple LED lamp beads 3031 in the first light group area D1 is opposite to the direction of the arrow formed by the multiple LED lamp beads 3031 in the third light group area D3. The multiple LED lamp beads 3031 in the second light group area D2 are arranged in a straight line. The multiple LED lamp beads 3031 in the second light group area D2 are between the multiple LED lamp beads 3031 in the first light group area D1 and the third light group area D3.
[0054] The PCB board 301 is equipped with a first position switch module 307a and a second position switch module 307b. The first position switch module 307a controls the on / off of the circuits of the first light group area D1 and the second light group area D2. The second position switch module 307b controls the on / off of the circuits of the second light group area D2 and the third light group area D3. The first position switch module 307a and the second position switch module 307b are both touch signal switches. The touch signal switch can be understood as a touch signal generated by clicking once. After a new touch is pressed, a new touch signal is generated. Figure 10 When the first position switch module 307a is touched, the first light group area D1 and the second light group area D2 are turned on. When the second position switch module 307a is touched, the second light group area D2 and the third light group area D3 are turned on.
[0055] In addition, the PCB board 301 is also provided with a switch conduction status monitoring module, which monitors the conduction status of the first position switch module 307a and the second position switch module 307b. Generally, there are only two situations: one is that the first position switch module 307a triggers the first light group area D1 and the second light group area D2 to be turned on, and the second position switch module 307b has no conduction action on the second light group area D2 and the third light group area D3; the second is that the second position switch module 307b triggers the second light group area D2 and the third light group area D3 to be turned on, and the first position switch module 307a has no conduction action on the first light group area D1 and the second light group area D2.
[0056] Combine Figure 6 、 Figure 7 A first orientation switch button 308a is configured on one side of the main shell structure 101, and a second orientation switch button 308b is configured on the other side of the main shell structure 101. The first orientation switch button 308a is aligned with the first orientation switch module 307a, and the second orientation switch button 308b is aligned with the second orientation switch module 307b.
[0057] Embodiment 2: The present invention provides a directional control method for a wireless guidance and indication device for fire evacuation, including the following contents:
[0058] First, after receiving a building fire alarm, security personnel in the monitoring room promptly identify a safe escape route based on surveillance observations. They then carry multiple guidance and indicator devices M to the safe escape route area. They hang the loops 105 of the guidance and indicator devices M on the protruding rods of expansion screws 6, which are pre-installed on the wall. The retaining rings 601 of the expansion screws 6 prevent the loops 105 from falling off. The security personnel then immediately press the switch button in the direction of the safe escape route.
[0059] Scenario 1: If the first position switch button 308a is in the same direction as the safe escape route, then the first position switch button 308a is pressed, and the PCB board 301 controls the LED lamp beads 3031 of the first light group area D1 and the second light group area D2 to flash at a preset frequency f. min It flashes and emits light to form the first type of light to guide the direction.
[0060] Scenario 2: If the second position switch button 308b is in the same direction as the safe escape route, then the second position switch button 308b is pressed, and the PCB board 301 controls the LED lamp beads 3031 of the third light group area D3 and the second light group area D2 to flash at the preset frequency f. min It flashes and glows to form a second light to guide the direction.
[0061] In the guidance and indication device M: the switch conduction status monitoring module obtains the conduction status of the first position switch module 307a and the second position switch module 307b on the PCB board 301, and thus knows which light guidance direction is the light guidance direction. The PCB board 301 transmits the light guidance direction information of the guidance and indication device M to the outside through the Bluetooth module 306. After the device is powered on, the Bluetooth module 306 of each guidance and indication device M automatically matches the Bluetooth modules 306 of other surrounding guidance and indication devices M, thereby quickly obtaining the corresponding light guidance direction information.
[0062] Taking the current guidance indicator device M as the center, the Bluetooth module 306 acquires the light guidance direction information from N adjacent guidance indicator devices M. For example, if N = 3, the light guidance direction information from three guidance indicator devices M in the "upstream" direction is acquired, and the light guidance direction information from three guidance indicator devices M in the "downstream" direction is acquired. If the guidance indicator device M is at the beginning of the route, it may only have a single-sided signal acquisition source.
[0063] Case 1: If the light guidance direction of the current guidance indicator device M is the same as the light guidance directions of M guidance indicator devices M among the N adjacent guidance indicator devices M, then the light guidance direction of the current guidance indicator device M is normal, wherein M / N≥0.7.
[0064] Scenario 2: If the light guidance direction of the current guidance indicator device M is opposite to the light guidance directions of M of the N adjacent guidance indicator devices M, then there is an abnormality in the light guidance direction of the current guidance indicator device M. The PCB board 301 adjusts the light guidance direction of the current guidance indicator device M to a direction opposite to the original light guidance direction. This situation may be caused by a mistake made by the security personnel. For example, the light guidance direction of the current guidance indicator device M was originally the first light guidance direction, but the light guidance directions of other upstream and downstream guidance indicator devices M are all the second light guidance direction. In this case, the PCB board 301 adjusts the light guidance direction of the current guidance indicator device M to the second light guidance direction.
[0065] Then, combine Figure 11 , security personnel hang and arrange the guiding indicator device M along the safe escape route, and the people in the building escape safely and quickly along the direction indicated by the guiding indicator device M.
[0066] In addition, when the sound sensor module 304 detects that the sound decibel is greater than the preset reference value or the infrared sensor module 302 detects the presence of a human body, the voice output module 305 outputs a prompt sound, for example, playing "Please follow the direction indicated by the light" to the outside world through the voice speaker 404, and at the same time, the LED lamp beads 3031 in the light group area that has been turned on flash at a preset flashing frequency f max Flashing light is performed, where fmax >f min When there are crowds nearby or the infrared monitor detects a person, the indicator light frequency speeds up to facilitate observation. When there are no crowds nearby or the infrared monitor detects no person, the indicator light frequency slows down to save energy.
[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
