Description

Disaster Prevention System of Visible Light Communication

The present invention relates to a technical field related to disaster prevention equipment, in particular to a disaster prevention system of visible light communication.

Disaster detection and avoidance are mostly achieved through the sensing of sensors, such as fire alarms, smoke sensors, and so on. These sensors and alarms for different purposes will be installed in different areas to detect and warn these areas to achieve the purpose of disaster detection and warning.

In a perfect environment (such as buildings), there is no problem in setting up various sensors, but in construction sites (such as new construction sites, mines, tunnels, potholes, road underground pipelines, sewers, etc.), there is no such problem. Easy, the construction equipment and location of the construction site will continue to move; therefore, it is impossible to install sensors in the current construction area in time, and it is also impossible to promptly remind people in the vicinity of the disaster to evacuate.

In addition, the sensor settings of the previous technology are designed in advance according to requirements or regulations, and it is impossible to move the position arbitrarily or add sensors with different functions in the future. In addition, the warning device is fixed in a specific location, and it cannot be moved outside and cannot ensure that all personnel in the area are actually warned, especially in noisy or disaster environments.

In view of the above-mentioned problems and deficiencies, the main purpose of the present invention is to To provide a disaster prevention system for visible light communication.

According to the above objective of the present invention, a disaster prevention system for visible light communication is proposed, which includes at least one hot spot lighting, at least one disaster sensor, at least one transceiver device, and at least one management system. The hot spot lighting provides lighting source and message transmission. The disaster sensor detects disasters and communicates with hot spot lights. The transceiver device is installed on the user's body to output a risk avoidance reminder based on the message trigger. The management system is connected to the hot spot lighting. With the composition of the above components, when a hazard in a certain area is sensed by the disaster sensor, it is transmitted to the management system through the hot spot lighting, and the management system is transferred to the preset hot spot lighting according to the preset plan to change the frequency of the light source and play the message , Trigger the transceiver device to prompt the person who is equipped with the transceiver device to avoid disasters in real time.

Figure 2 is a block diagram of a partial unit of the embodiment shown in Figure 1.

Hereinafter, please refer to the related drawings to further describe the embodiments of the visible light communication disaster prevention system of the present invention. In order to facilitate the understanding of the embodiments of the present invention, the same components are described below with the same symbols.

Please refer to Figures 1 and 2, the disaster prevention system related to the visible light communication of the present invention includes at least one hot spot light 10, at least one disaster sensor 20, at least one transceiver device 30, a gateway 40, and one Management system 50.

The above-mentioned hot spot lighting lamp 10 provides lighting light for the visible light communication lamp Light-Fidelity (Li-Fi) and the transmission of disaster information and hazard information, and At the same time that the information of avoidance is transmitted, the spectrum of the illumination light can be adjusted to 200K~300K frequency band output. In implementation, the luminous body of the hot spot lighting lamp 10 can be a light emitting diode (LED) or a laser diode (LD) or the like.

The disaster sensor 20 is configured at a preset position corresponding to the light range of the hot spot lighting 10, and includes a sensing unit 22 and a transceiver unit 24 (Li-Fi dongle). The aforementioned sensing unit 22 is used to sense disasters in the surrounding environment, such as smoke, earthquakes, fires, floods, toxic gases, and explosions, etc., and output disaster messages when triggered. The aforementioned transceiver unit 24 is electrically connected to the sensing unit 22 and transmits the disaster information to the hot spot lighting lamp 10. In implementation, the sensing unit 22 can be a gas sensor, a dust sensor, a temperature sensor, a liquid level sensor, a vibration sensor, etc.

The above-mentioned transceiver device 30 is mounted on the user to receive the risk avoidance message transmitted by the hot spot lighting 10, and to remind the user of risk avoidance. When implemented, the danger avoidance reminding method of the transceiver 30 may be flashing light, vibration, alarm sound, tightening, tingling sensation, etc. for notification. In implementation, the transceiving device 30 may be a mobile phone, a tablet, or an electronic wristband.

The above-mentioned management system 50 can be a computer, a microprocessor, a cloud server, or a fog-end server; it forms a communication connection with the hot spot lighting 10 through the gateway 40, and receives disaster information transmitted by the hot spot lighting 10, optionally In response, the hot spot lighting lamp 10 that outputs the risk avoidance message to the matching position triggers the transceiver device 30.

Therefore, the foregoing is an introduction to the various components and assembly methods of the visible light communication disaster prevention system of a preferred embodiment of the present invention. Hereinafter, the features of the embodiments of the present invention are introduced as follows.

The construction environment (such as tunnel engineering) is divided into multiple areas, and hot spot lighting 10 is set in different areas to provide necessary lighting sources for different areas, and each hot spot lighting 10 can be performed through the gateway 40 and the management system 50 respectively Communication connection. In addition, in accordance with the disaster prevention requirements of different areas, corresponding disaster sensors 20 are set within the illumination range of the hot spot lighting 10 to detect disasters in different areas.

When the disaster sensor 20 in a certain area (for example, area A) is triggered, the disaster information is transmitted to the management system 50 via the hot spot lighting lamp 10 through the gateway 40, and the management system 50 controls the preset area ( For example, the hot spot lighting lamp 10 in area B) outputs the risk avoidance message through the gateway 40 and adjusts the spectral output frequency band (200K~300K), so that the transceiver device 30 in the area is triggered by the risk avoidance message to output a risk avoidance reminder. The user avoids danger, and reminds the user in the area by the change of the spectral output of the hot spot illuminator 10.

Since the disaster sensor 20 communicates with the hot spot illuminator 10 through the frequency of light, it does not need to be fixed at a specific location, as long as the hot spot illuminator 10 is within the illuminance range, so it can be moved arbitrarily as required. In addition, the transceiver 30 is mounted on the user, and can also be moved arbitrarily with the personnel, so as to achieve real-time disaster detection and real-time (determined) notification for the purpose of avoiding danger.

The above description is only the preferred embodiments of the present invention, and is intended to clarify the characteristics of the present invention, and is not intended to limit the scope of the embodiments of the present invention. Those skilled in the art make equal changes based on the present invention. , And changes well known to those skilled in the art should still fall within the scope of the present invention.
