Description

Technical Field

[0001] The present invention relates to the technical field of lighting control, and in particular to an intelligent lighting control system and method. Background Art

[0002] The intelligent lighting control system utilizes advanced computer technology, network communication technology, intelligent cloud control, integrated wiring technology, and medical electronic technology in accordance with ergonomic principles, integrating individual needs, and organically combining various lighting-related subsystems such as security, lighting control, curtain control, gas valve control, information appliances, scene linkage, floor heating, health care, sanitation and epidemic prevention, security, etc. Through networked integrated intelligent control and management, a new "people-oriented" lighting experience is achieved.

[0003] At present, the lighting management for commercial or home use is extensive, either without management or with a single form of management. The current lighting system is isolated in terms of manual / automatic, local / remote control. This organically integrates remote control, manual control and automatic control into one, achieving seamless connection of various control modes without the need to switch any control modes. Summary of the invention

[0004] In view of this, an object of the present invention is to provide an intelligent lighting control system and method to solve the problems in the background technology.

[0005] An intelligent lighting control system of the present invention includes a central processing unit, the input end of the central processing unit is provided with an AD-DC power supply module, a fire bus interface module, a conference system interface module, a projector status detection interface module, a space occupancy interface module, an indoor illumination interface module, an electric energy metering module and an 86 panel interface module, the output end of the central processing unit is provided with a dimming module and an output decision module, the central processing unit is bidirectionally connected with a communication module, the 86 panel interface module is also connected to the input end of the output decision module, the output end of the output decision module is connected with a Kout relay, the output end of the Kout relay is connected to the input end of the electric energy metering module, and the output end of the fire bus interface module is also connected to the input end of the Kout relay.

[0006] Furthermore, the communication module is a Lora module, a WiFi module, a Zigbee module, a Bluetooth module or an RJ45 Ethernet module.

[0007] Furthermore, the central processing unit adopts an STM32L151C8T6 processing chip, wherein pins 11, 13, and 15 of the central processing unit are respectively connected to an 86 panel interface module, a conference system interface module, and a communication module, pin 31 is connected to an electric energy metering module, pins 39 and 41 are respectively connected to a space occupancy interface module and a projector status detection interface module, and pins 46, 25, and 28 are respectively connected to an indoor illumination interface module, a lamp status module, and a fire bus interface module.

[0008] Furthermore, the communication module is used to receive control instructions from various remote devices such as computers or mobile smart terminals. When the remote device issues an on / off instruction, the central processor receives the instruction and controls the on / off of the lamp by controlling the on / off of the Kout transmitter.

[0009] Furthermore, there are multiple space occupancy interface modules, including infrared modules or ultrasonic modules. When it is detected that someone enters or there is no one in the meeting room, the lamps are automatically turned on and off according to the preset logic. They are installed in an independent space that requires manual intervention in conjunction with the 86 panel interface module. The dimming and indoor illumination interface module share the IIC bus. This module is connected to the dimming interface of the LED lamp. Depending on whether the indoor lamp supports dimming, if it supports dimming, this module has the function of sending dimming signals in the form of 0~10V, 1~10V, PWM, etc., to infinitely adjust the brightness of the lamp.

[0010] Furthermore, when the Kout relay is closed, the module detects the power consumption of the lamp in real time, detects the current voltage, current, and power, and records the power consumption after the local light is turned on in real time. The power metering module sends this data to the central processor in real time, and then the central processor sends it to the energy metering system or other systems.

[0011] Furthermore, the output decision module is composed of a pure mechanical relay, and receives signals from the central processing unit and the 86 panel interface module at the same time, and judges the signal output based on the state change of the signal. When any input changes state, the output decision module will send the current changed state to the Kout relay. When the central processing unit fails, the signal sent by the central processing unit to the output decision module will no longer change, and the output decision module will control the Kout relay based on the switch signal of the 86 panel interface module, thereby achieving the purpose of not affecting the on-site use when the central processing unit fails, or local manual lighting control intervention can be performed at any time.

[0012] Furthermore, an intelligent lighting control method,

[0013] S1: The central processor is used to receive the status and information of various external devices. The signals include switch quantity, analog quantity and text message, and perform corresponding switch quantity output according to the preset logic, analog quantity output or send messages to the upper computer through various communication modules. After the central processor receives various space occupancy signals, it shields low-level switch light operations according to the current lamp status. After receiving the conference log message sent by the conference system, it adjusts the indoor lights to the corresponding state according to the preset scene. If a fire alarm signal is received, that is, the fire status changes from 0 to 1, no matter what state it is in, the central processor shields all operations and immediately sends a fire alarm notification to the upper computer. At the same time, the fire alarm signal drives the Kout relay to force the indoor lighting to turn on;

[0014] S2: The fire bus interface module is used to parse the forced light-on command sent by the fire host. On the one hand, the fire bus module transmits the command of the fire host to the central processor, which is sent to various remote devices by the central processor through the communication module. In addition, the module directly controls the Kout relay to directly start the lighting, and uses the original indoor lighting as fire emergency lighting;

[0015] S3: When the panel switch changes state from "on" to "off" or from "off" to "on", the output decision module learns that manual intervention of the lamp will be carried out on site. At this time, the output decision module increases the priority of the mechanical panel control and controls the Kout relay according to the panel control signal. At the same time, the central processor will also obtain the event of the panel state change. At this time, the central processor notifies the remote control device through the communication module that the local control is to be carried out locally and no control commands are sent. At the same time, the central processor no longer accepts various external signals and completely hands over the control of the conference system, space occupancy module, indoor illumination interface module, and projector signal to the local 86 panel;

[0016] Furthermore, when the central processing unit crashes for some reason and can no longer control the lamp, the mechanical panel switch is not affected and can continue to control the switch of the lamp.

[0017] Furthermore, the conference system interface module is connected to a third-party conference system via Ethernet. Through commands sent from the conference system, the light control can adjust the lighting scene in the conference room in real time according to the conference status.

[0018] Furthermore, the indoor illumination interface module and the dimming module share the IIC bus, and obtain the indoor illumination conditions through the light sensor. When set to automatic control, the light control will automatically adjust the brightness of the lamps according to the preset illumination.

[0019] Beneficial effects of an intelligent lighting control system and method of the present invention: The present invention intelligently calls all indoor lighting switches in the event of a fire through the output arbitration module and Kout relay, and has the highest priority, and automatically adjusts the lighting status of the conference room or other spaces under the information monitoring of the space occupancy module. And when the 86 panel switch is manually intervened, the manual intervention has the highest priority, and the isolation of local / remote control is truly achieved, remote control, manual control and automatic control are organically integrated, and various control modes are seamlessly connected without switching any control mode.
