Detailed Description
The present invention will be described in further detail with reference to examples.
Referring to fig. 1, a building fire safety path indicating system and method thereof includes a fire information collecting module 10, a controller 20, a wireless communication module 30, a cloud server 40 (a rescue path planning system 41 and an evacuation path planning system 42), a power module 50, an RFID personnel identification module 60, and a laser path indicating device 70. The power module 50 provides power for the system; the controller 20 receives the information collected by the fire information module 10; the RFID personnel identification module 60 identifies personnel carrying RFID tags; the controller 20 controls the collected fire information and the RFID identification information to be forwarded to the cloud server 40 through the wireless communication module 30; the cloud server 40 performs path planning calculation on the received information and the building model, and returns an action command of the laser path indicating device 70 of each monitoring node through the wireless communication module 30.
After a fire occurs, the controller 20 collects relevant parameters such as smoke, temperature, and carbon monoxide concentration through the fire information collection module 10, and transmits the relevant parameters to the cloud server 40 through the wireless communication module 30.
The wireless communication module 30 is connected to the controller 20, so as to transmit data and control commands between the controller 20 and the cloud server 40.
The power module 50 is connected with each module, and is powered by mains supply through a voltage reduction circuit in daily life. In case of fire, the power supply of a 2000mAh lithium battery is mainly used after the building is powered off. The two power supply modes can be intelligently switched.
The RFID personnel identification module 60 monitors the personnel passing through the node in real time, and if the personnel passes through the node, the controller 20 receives the serial number of the fire fighter and sends the serial number of the fire fighter to the cloud server. Rescue path system 41 will calculate a corresponding rescue path for it. If no person passes (no identification of the RFID device) or the trapped person carrying the RFID tag passes, the controller 20 sends information of the trapped person to the cloud server 40, and the evacuation path planning system 42 calculates an escape evacuation path for the trapped person. When a firefighter and a trapped person are simultaneously detected, the controller 20 uploads the identity information of the trapped person to the cloud server 40 and calculates an escape evacuation path, and later uploads the firefighter's number and calculates a rescue path for the firefighter.
The laser path indicator 70 is connected to the controller 20. The cloud server 40 transmits a command to the controller 20 through the wireless communication module 30, and controls the laser path indicator 70 to complete a corresponding action. Specifically, the cloud server 30 sends a control command to the node controller 20 with a certain number, and the controller 20 sends an action command to the laser path indicator 70 through the output port, thereby completing dynamic path indication. The laser transmitter is driven by the motor to scan back and forth in the direction to be indicated, and sectors with certain angles irradiate the emergency marker lamp, so that the emergency marker lamp emits light on one side, and the function of path indication is completed.
Referring to fig. 2, 3, 4 and 5, a laser path indicating device 70 includes a laser generator 71, a motor 72 and an emergency marker lamp 73. Two laser generators 711 are arranged in the laser transmitter 71, and the hard plastic shell 710 is fixed with filler sponge through a clamping seat and wraps the laser generators 711. The laser generator 711 uses a general laser diode, and mainly emits green light or red light. The controller 714 of the laser generator contains a power supply 715 (button cell) which is connected with the power interface 713 of the laser generator 711 through a switch circuit to supply power to the laser generator 711. The wireless power coil 712 is connected to the laser generator controller 714 via a data and command connection 716 to provide switching information and power to the laser generator. The wireless power supply coil 712 is divided into a secondary coil rotating with the laser transmitter and a primary coil fixed on the motor 72, which are distributed around the rotor 720 of the motor 72 with a small gap.
The rotor 720 of the motor 72 is connected to the rigid plastic housing 710 by screws 724. The motor housing 722 is connected with the fixed interface 721 of the motor by welding, and the controller 20 is connected with the control end interface 723 of the motor by a data line, so as to control the laser path indicator.
The specific control process is as follows:
the method comprises the following steps:
the cloud server 40 sends a control command to a certain node controller 40 through the wireless communication module 30;
step two:
the controller 20 receives the control command and controls the rotation angle and the back-and-forth rotation of the motor 72 by outputting the pulse number and the sequence, the motor 72 firstly rotates clockwise from the initial direction (the front east) to the target direction (the pulse number control), then the motor 72 rotates forward for a certain angle in the target direction and rotates backward for a certain angle, and the purpose of laser scanning is achieved;
step three:
the controller 20 provides a high-frequency current signal for the wireless power supply coil 712, the laser controller 714 obtains starting energy through the induction coil, and the laser generator 711 is turned on;
step four:
when the end instruction is given, the motor 72 rotates back to the initial position (e.g., east), the controller 20 stops supplying current to the wireless power supply coil 712, the laser controller 714 cannot acquire the induced current signal through the induction coil, and the laser generator 711 is turned off.
The emergency marker light 73 is changed based on the common emergency sign, and comprises an LED light bar 731, a hook 730, a photoresistor 732 (which is particularly sensitive to laser beams), and an external power plug 734. If the photo resistor 732 is irradiated with laser light, the LED light bar 731 on the irradiated surface is turned on, and if not, the LED light bar 731 is turned off. The internal power supply is a lithium battery and needs to be charged by an external power supply, and the power supply mode is the coexistence of the lithium battery power supply and the commercial power supply. The emergency marker lamp has an LED light bar 731 and a photo resistor 732 on both sides thereof, and has different responses to laser light irradiated in different directions.
Referring to fig. 6, a schematic diagram of a laser path indicating device is shown, in which an emergency marker lamp 73a and an emergency marker lamp 73b are separated by 5 meters, and a laser path indicating transmitter 71a and a motor 72a are disposed therebetween and separated from the emergency marker lamp by 2.5 m. The building fire safety path indicating system detection node 10 is connected to the laser path indicating device 70a by a bolt. This makes it possible to construct a simpler path indicating unit. Such path indicating units may be placed under the ceiling of various building interior passages, corridors, stairways, halls, rooms, etc. Therefore, the path can be effectively indicated when a fire disaster occurs. In the drawing, 4 denotes a laser beam, 5 denotes a sight line of an evacuee, 6 denotes a safety exit sign, and 7 denotes a gate of a building to the outside.
