Description

Technical Field

[0001] The present application relates to the field of fire emergency lighting, and in particular to a fire emergency lighting based on the Internet of Things. Background Art

[0002] Fire emergency lights are suitable for fire emergency lighting and are the most common lighting tools in fire emergencies. They have a long emergency time, high brightness and an automatic emergency function when the power is off. Traditional fire emergency lights are generally equipped with lighting lamps and indicator lights. The indicator lights are used to indicate the location of the escape route. The lighting lamps light up when the power is off. Since the direction of the indicator lights on the existing fire emergency lights is fixed, the direction they can indicate is also fixed, usually pointing to the escape route closest to them. Generally, large-scale buildings have multiple escape routes. When a fire occurs indoors, if there are too many people indoors and the direction of the fire emergency lights is fixed, many people will flee to the escape route in the direction it indicates. Therefore, it may cause an escape route to be abnormally crowded, while other escape routes are sparsely populated. Crowded escape routes not only affect the escape efficiency, but may also cause stampedes. Therefore, reasonable diversion of escapees to ensure the efficiency of escape is an urgent problem that needs to be solved by fire emergency lights. Summary of the invention

[0003] In order to improve the problem that traditional fire emergency lights have fixed indication directions and uneven drainage of escaping personnel, the present application provides a fire emergency lighting lamp based on the Internet of Things.

[0004] The present application provides a fire emergency lighting lamp based on the Internet of Things, which adopts the following technical solution: comprising a shell and a cover body, the cover body is detachably connected to the front end of the shell body, a constant light indicator, a forward direction light and a reverse direction light are fixed on the cover body, a smoke sensor, a power module, a sound sensor and a central control module are arranged in the shell body, and a communication module is arranged on the central control module;

[0005] The positive direction light and the reverse direction light are in opposite directions. The positive direction light and the reverse direction light respectively form two indicator lights in opposite directions with the constant light indicator. Only one of the positive direction light and the reverse direction light is powered on and lights up at the same time.

[0006] The lighting of the forward direction light and the reverse direction light is selected by the central control module according to the result of comparing the number of people in multiple channels.

[0007] Preferably, two lighting lamps are fixed on the shell, and the lighting lamps are powered by a power module.

[0008] Preferably, the sound sensor is connected to the lighting lamp and controlled by a central control module, and when the sound sensor detects the sound of a person passing by, the brightness of the lighting lamp is increased and maintained for thirty seconds.

[0009] Preferably, the central control module is connected to the communication module, and the central control module records the number of times the brightness of the lighting lamp increases and the total duration of the brightness increase, and compares the data recorded by the central control modules in the remaining fire emergency lights through the communication module to compare the number of people in each escape channel.

[0010] Preferably, the forward direction light and the reverse direction light are connected to the central control module, the always-on indicator light is in a always-on state, and the central control module controls the forward direction light or the reverse direction light to light up according to the comparison result of the number of people in each escape channel, so as to guide people to the escape channel with fewer people.

[0011] Preferably, the power module includes a battery and a power management circuit.

[0012] Preferably, a plurality of ventilation holes are provided on a side wall of the housing close to the smoke sensor.

[0013] Preferably, the smoke sensor is connected to a central control module. When the smoke sensor detects smoke, the central control module controls the lighting lamp to light up, and at the same time, the central control module controls the forward direction lamp or the reverse direction lamp to light up.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] 1. The sound sensor detects the sound when people pass by, and uses the central control module to control the lighting to increase the brightness and maintain it for thirty seconds. When people pass by, the brightness of the lighting increases for the escape passage, facilitating people to escape. When no people pass by, the brightness of the lighting decreases to reduce power consumption, thereby extending the battery power supply time and increasing the working time of the fire emergency light.

[0016] 2. Use the communication module to realize communication between multiple fire emergency lights, so that multiple fire emergency lights can communicate data, so as to determine the number of escapees in each fire passage, thereby realizing the reasonable diversion of escapees and reducing congestion in escape passages.

[0027] The GPIO34 pin of ESP32 is connected to the MQ-2AO pin to read the smoke concentration, the GPIO14 pin of ESP32 is connected to the KY-038DO pin, the GPIO25 pin of ESP32 is connected to the relay control terminal IN, the GPIO positive direction light pin 21 of ESP32 is connected to the DS3231 SDA, and the GPIO reverse direction light pin 22 of ESP32 is connected to the DS3231 SCL;

[0028] The positive direction light 21 and the reverse direction light 22 are in opposite directions. The positive direction light 21 and the reverse direction light 22 form two indicator lights in opposite directions with the constant light indicator 20. Only one of the positive direction light 21 and the reverse direction light 22 is powered on and lights up at the same time. The positive direction light 21 and the reverse direction light 22 use LED lamp beads. The anodes of the positive direction light 21 and the reverse direction light 22 are connected to the GPIO26 pin and the GPIO27 pin of the ESP32 respectively.

[0029] The lighting of the positive direction light 21 and the reverse direction light 22 is selected by the central control module 70 according to the result of comparing the number of people in multiple channels.

[0030] Two lighting lamps 13 are fixed on the housing 10. The lighting lamps 13 use 3W COB LEDs. The lighting lamps 13 are connected to the GPIO lighting lamp 13 pins of ESP32. The lighting lamps 13 are driven by MOS tubes and powered by a power module.

[0031] The sound sensor 60 is connected to the lighting lamp 13 and is controlled by the central control module 70. When the sound sensor 60 detects the sound of a person passing by, it controls the lighting lamp 13 to increase its brightness and maintain it for thirty seconds.

[0032] The central control module 70 is connected to the communication module 30. The central control module 70 records the number of times the brightness of the lighting lamp 13 increases and the total duration of the brightness increase. The data is compared with the data recorded by the central control module 70 in other fire emergency lights through the communication module 30 to compare the number of people in each escape channel.

[0033] The forward direction light 21 and the reverse direction light 22 are connected to the central control module 70, and the constant light indicator 20 is in a constant light state. The central control module 70 controls the forward direction light 21 or the reverse direction light 22 to light up according to the comparison result of the number of people in each escape passage, so as to guide people to the escape passage with fewer people.

[0034] The power module includes a battery 50 and a power management circuit. In this embodiment, the power management circuit uses a TP4056 charging module, and the battery 50 uses an 18650 lithium battery. The relay SRD-05VDC-SL-C (5V) is used to switch to battery power supply when the city power is cut off. The battery 50 and the central control module 70 are connected through an LM2596 step-down module.

[0035] A plurality of ventilation holes 12 are formed on a side wall of the housing 10 close to the smoke sensor 40 .

[0036] The smoke sensor 40 is connected to the central control module 70. When the smoke sensor 40 detects smoke, the central control module 70 controls the lighting lamp 13 to light up. At the same time, the central control module 70 controls the forward direction lamp 21 or the reverse direction lamp 22 to light up, and the constant light indicator 20 is always in a constant light state.

[0037] Working process of this application:

[0038] S1. Normal mode. In this mode, the AC power is supplied, the relay SRD-05VDC-SL-C (5V) is closed, the TP smoke sensor 4056 charges the battery, the central control module 70 controls the positive direction light 21 (or the reverse direction light 22) to light up, the positive direction light 21 (or the reverse direction light 22) and the constant light indicator 20 are combined to point to the direction of the nearest escape passage, and the central control module 70 reads the detection value of the smoke sensor 40 once a second.

[0039] S2, emergency mode, when a fire occurs, the smoke sensor 40 is triggered, and the central control module 70 controls the lighting lamp 13 to light up. When the sound sensor 60 detects that someone passes by, it transmits a signal to the central control module 70, and controls the lighting lamp 13 to increase in brightness for thirty seconds. If the city power is cut off at this time, the relay SRD-05VDC-SL-C (5V) is disconnected and switched to the battery 50 for power supply. The direction of the escape passage pointed to by the combination of the positive direction light 21 and the always-on indicator light 20 is the preset direction.

[0040] S3, data recording, when a person passes by, the sound sensor 60 detects the sound of the person passing by, then controls the lighting lamp 13 to increase its brightness, the real-time clock module DS3231 RTC module starts a thirty-second countdown, and records the event. If the sound sensor 60 detects a person passing by again within the thirty-second countdown, the countdown is reset and the event is recorded again.

[0041] S4. Data comparison. The central control module 70 in each emergency fire light uploads the recorded data to the Alibaba Cloud IoT platform (or the local Mosqu itto MQTT Broker) through the MQTT protocol every 5 minutes, and compares the density of people in each escape channel. If the density of people in a certain channel is too large, the data comparison result and the control result are transmitted to the fire emergency light pointing to the escape channel. Then the central control module 70 in these fire emergency lights controls the positive direction light 21 to turn off and the reverse direction light 22 to turn on, so as to guide the escapees to the remaining escape channels, thereby avoiding crowding in a certain escape channel and ensuring escape efficiency. The central control module 70 is provided with a switching anti-shake program, that is, the indication direction is switched at most once within fifteen minutes.
