Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lighting equipment, in particular to an emergency indicator control system. Background Art
[0002] Emergency indicators are lighting equipment used to indicate the evacuation direction. Emergency indicator signs such as "Safety Passage" and "Go This Way" are set on the emergency indicators to help people clarify the evacuation direction. Generally, the flame color at the fire scene is yellow, and the contrast between green and yellow is strong, with good recognition performance. Therefore, currently, the color of emergency indicators is green.
[0003] However, in fact, during a fire, the coverage area of thick smoke is often wider. In other words, there may not be fire in the corridor, but the smoke will spread into the corridor. The penetration performance of green light is worse than that of red light. Summary of the Utility Model
[0004] Therefore, in view of the above problems, the utility model proposes an emergency indicator control system, which can intelligently change the light-emitting color according to whether there is fire or thick smoke in the environment, facilitating indication.
[0005] To achieve the above object, the utility model adopts the following technical solutions:
[0006] An emergency indicator control system includes a bottom case, a red lamp tube, a green lamp tube, a light guide plate, an indicator panel provided with an emergency indicator sign pattern, a control circuit board, a far-infrared flame sensor, a smoke concentration sensor, and a power interface provided on the bottom case;
[0007] Installation grooves for installing the red lamp tube, the green lamp tube, the light guide plate, and the control circuit board are formed on the bottom case. The red lamp tube and the green lamp tube are respectively installed on different sides of the light guide plate. The indicator panel is hermetically covered on the opening of the installation groove;
[0008] Both the far-infrared flame sensor and the smoke concentration sensor are installed on the surface of the indicator panel;
[0009] A rechargeable power source, an AC-DC converter, a charging protection circuit module, a processor, a first relay switch module, and a second relay switch module are integrated on the control circuit board;
[0010] The power interface is electrically connected to the rechargeable power supply through an AC-DC converter and a charging protection circuit module in sequence. The rechargeable power supply is electrically connected to the processor. The rechargeable power supply is electrically connected to the green lamp tube through a first relay switch module to form a conductive loop. The rechargeable power supply is electrically connected to the red lamp tube through a second relay switch module to form a conductive loop. The control ends of the first relay switch module, the second relay switch module, the far-infrared flame sensor, and the smoke concentration sensor are respectively electrically connected to the processor.
[0011] Further, a buzzer is also integrated on the control circuit board; the buzzer is electrically connected to the processor.
[0012] Further, the first relay switch module adopts a normally closed relay switch, and the second relay switch module adopts a normally open relay switch.
[0013] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows:
[0014] This emergency indicator control system detects whether there is a flame in the surrounding environment through the far-infrared flame sensor, and detects the smoke concentration in the surrounding environment through the smoke concentration sensor. When a flame is detected in the environment, but the smoke concentration is less than the preset value, the green lamp tube is controlled to light up, and the red lamp tube does not light up. The green light irradiates the indicator panel, and the contrast with the flame color is strong, and the recognition performance is good. When the smoke concentration in the surrounding environment exceeds the preset value, the green light cannot effectively penetrate the smoke, affecting the effect of the emergency indicator. Therefore, the green lamp tube is controlled not to light up, and the red lamp tube lights up. At this time, the red light irradiates the indicator panel, and the red light can penetrate thick smoke, and the emergency indication effect is good.
[0015] Further, when a flame or smoke is detected in the surrounding environment, the buzzer sounds to prompt personnel to evacuate. Description of the Drawings

[0021] Reference Figure 1 , Figure 2 , Figure 3 , and Figure 4 , this embodiment provides an emergency indicator control system, including a bottom case 1, an indicator panel 2 provided with an emergency indicator pattern, a light guide plate 3, a control circuit board 4, a green lamp tube 5, a red lamp tube 6, a far-infrared flame sensor 7, and a smoke concentration sensor 8. The emergency indicator pattern is an existing pattern, and different emergency indicator patterns can be selected according to needs, which will not be elaborated in detail here.
[0022] An installation groove 11 for installing the light guide plate 3, the control circuit board 4, the green lamp tube 5, and the red lamp tube 6 is formed on the bottom case 1. The green lamp tube 5 and the red lamp tube 6 are respectively installed on different sides of the light guide plate 3. In this specific embodiment, the green lamp tube 5 is installed on the upper side of the light guide plate 3, and the light emitted by the green lamp tube 5 can propagate along the light guide plate 3; the red lamp tube 6 is installed on the lower side of the light guide plate 3, and the light emitted by the red lamp tube 6 can propagate along the light guide plate 3.
[0023] The indicator panel 7 is hermetically covered on the notch of the installation groove 11, and both the far-infrared flame sensor 7 and the smoke concentration sensor 8 are arranged on the surface of the indicator panel 7.
[0024] A processor 41, a rechargeable power source 42, a charging protection circuit module 43, an AC-DC converter 44, a first relay switch module 45, a second relay switch module 46, and a buzzer 47 are integrated on the control circuit board 4. In this specific embodiment, preferably, the processor 41 uses an ESP32-S3 chip; the first relay switch module 45 uses a normally closed relay switch, and the second relay switch module 46 uses a normally open relay switch. The AC-DC converter 44 is used to convert mains power into direct current for power supply. The above-mentioned various electronic components are all existing devices. Those skilled in the art should have the conventional selection ability of the above-mentioned various electronic components, and those skilled in the art can reproduce the emergency indicator control system disclosed in this patent application and produce the same technical effects according to this specification and the accompanying drawings after a limited number of circuit connection experiments.
[0025] The connection modes of the above-mentioned various electronic components are as follows:
[0026] The power interface 12 is electrically connected to the rechargeable power source 42 through the AC-DC converter 44 and the charging protection circuit module 43 in sequence to charge the rechargeable power source 42. When in use, the power interface 12 is connected to the mains power.
[0027] The rechargeable power source 4 is electrically connected to the processor 41 to supply power to the processor 41.
[0028] The rechargeable power source 42 is electrically connected to the green lamp tube 5 through the first relay switch module 45 to form a conductive loop. By controlling the first relay switch module 45 to conduct or disconnect, the green lamp tube 5 is turned on or off.

[0032] When a flame is detected in the environment but the smoke concentration is less than the preset value, the processor 41 controls the green lamp tube 5 to turn on, and the red lamp tube 6 does not turn on. The green light irradiates the indicator panel 2, with a strong contrast to the flame color and good recognition performance.
[0033] When the smoke concentration in the surrounding environment exceeds the preset value, the green light cannot effectively penetrate the smoke, affecting the effect of the emergency indicator light. Therefore, the processor 41 controls the green lamp tube 5 not to turn on, and the red lamp tube 6 turns on. At this time, the red light irradiates the indicator panel 2, and the red light can penetrate thick smoke, with a good emergency indication effect.
[0034] When a flame or smoke is detected in the surrounding environment, the buzzer 47 sounds to prompt personnel to evacuate.
