Method and System for Controlling Data Transmission of Indoor Intelligent
Lighting
TECHNICAL FIELD
The invention relates to the technical field of communication and the field of automatic
control, in particular to a system for controlling data transmission of indoor intelligent
lighting, which comprises a data transmission method, a method for controling, related
equipment and chips.
BACKGROUND
Intelligent lighting, which merits in combining with Internet of Things (IoT) technology,
realizing automatic control of lighting, saving energy and reducing emission, and
improving user experience and living comfortness, has become a popular industry.
It is a common practice in related technologies to realize automatic switching of lighting
equipment by using sound perception, that is, sound control lighting, which can greatly
reduce the inconvenience caused by manual control and reduce unnecessary waste of
electric energy. The usage of lighting equipment in related art is not sent to the network
for analysis, so it is impossible to obtain the requirements and usage characteristics of
lighting equipment in specific scenes, such as lighting time period and illumination
intensity requirements. Therefore, based on the Internet of Things technology, the present
invention proposes a method and system for controlling data transmission of indoor
intelligent lighting, which utilizes various types of sensors to monitor indoor
environmental conditions such as different time periods, different lighting intensities and
different application requirements, thus realizing the transmission of monitored data
through wireless transmission technology, and realizing the automatic control of lighting equipment in indoor scenes, and intelligently controls indoor lighting based on big data analysis of lighting requirements.
SUMMARY
The present invention is to provided a method for controlling data transmission, a device,
a system for controlling and also a software of indoor intelligent lighting system. It's
aiming at solving the problems of automatic and intelligent control and data analysis of
lighting equipment in indoor scenes through Internet of Things technology and big data
technology.
For a better description, the equipment providing wireless data service for lighting
equipment is called as network access point, which can be a base station of a small area
or a Wi-Fi access device. The wireless communication technology in the Internet of
Things scene in the present invention is based on NB-IoT (Narrow Band-Internet of
Things), or the Internet of Things communication technology or evolution version such as
Wi-Fi, ZigBee, etc., or the 5G standard, or the unlicensed band Internet of Things
communication technology of MultiFire. The lighting equipment in the present invention
is a terminal device based on Wi-Fi, NB-IoT, ZigBee, etc, containing at least one
equipment including infrared sensors, sound sensors, illumination intensity sensors,
ultrasonic sensors, etc. A method and system for controlling data transmission of indoor
intelligent lighting comprises a master control unit and at least one cooperative control
unit. It is characterized in that:
The main control unit comprises a communication module and a processing module; The
communication module is used for communicating with the external network and the
cooperative control unit; The processing module is used for processing the sensing data transmitted by each cooperative control unit and the data sent by the external network and analyzing the data;
The cooperative control unit comprises at least an lighting module, a sensor module, a
processing module, a communication module and a power supply module; The lighting
module is used for indoor lighting; The sensor module is used for sensing the situation
change in the area where the lighting module of the cooperative control unit is located,
including the sound, the position or trajectory of the moving object, the illumination
condition and the moving object in the area.
There is no physical connection between the master control unit and the cooperative
control unit; The cooperative control unit and the sensor module may or may not be
physically connected; The cooperative control unit and the sensor module are
geographically separated or not separated; The sensor module senses the situation change
in the area where the lighting module is located, and can transmit the information to the
processing module of the cooperative control unit.
The processing module of the main control unit has capabilities including signal
processing, data storage and data analysis. And then, the processing module of the master
control unit sends the control mode of the lighting system to the cooperative control unit
for lighting control of this unit.
The processing module of the cooperative control unit that used for processing the data of
the sensor module has certain capabilities including data storage and data analysis, and is
able to analyze and discriminate scene conditions according to the data of the sensor
module, and control the on/off and illumination intensity adjustment of the lighting module of the cooperative control unit in combination with the control mode of the system.
In one case, the main control unit has a corresponding control panel for inputting the
control modes of the lighting system, including manual control and automatic control. In
the second case, the main control unit has no corresponding control panel.
In one case, the cooperative control unit has a corresponding manual switch device,
which turns on and off the lighting module of the cooperative control unit regardless of
the change of regional conditions sensed by the sensor module of the cooperative control
unit. In the second case, the cooperative control unit has no corresponding manual switch
device, and the on/off and brightness level of the lighting module of the cooperative
control unit depend on the lighting control mode of the master control unit and the change
of regional conditions sensed by the sensor module of the cooperative control unit.
In one case, the control panel of the master control unit inputs the manual control mode,
and the on/off and brightness level of the lighting module of the cooperative control unit
are forced to perform by the manual control mode of the master control unit, which has
nothing to do with the change of regional conditions sensed by the sensor module of the
cooperative control unit and the manual switching device of the cooperative control unit.
In the second case, the control panel of the master control unit inputs the automatic
control mode, and the on/off and brightness level of the lighting module of the
cooperative control unit are controlled by the manual switch device of the cooperative
control unit.
In the third case, the control panel of the master control unit inputs the automatic control
mode, and the on/off of the lighting module of the cooperative control unit is related to the change of regional conditions sensed by the sensor module of the cooperative control unit.
A method and system for controlling data transmission of indoor intelligent lighting
includes lighting equipment, network access points and control devices. The system
includes a master control unit and several cooperative control units, wherein the master
control unit is responsible for the internal control of the whole system, information
interaction with external networks and cooperative control units, and recording and
transmitting the data of the lighting system usage. It includes a processing module with
ability of strong computing and data reading and writing, a storage module for storing
data and a wireless transceiver module for providing wireless data services. The
cooperative control unit has the functions of sensing the situation change in the area
where the lighting module of the cooperative control unit is located, controlling the
brightness of the lighting module of the cooperative control unit, uploading sensing data
and uploading the lighting state of the cooperative control unit, and comprises a processor
with certain basic computing capability, at least one sensor module, a lighting module
and a communication module, or further, the cooperative control unit also comprises a
manual switch device. A method and system for controlling data transmission of indoor
intelligent lighting comprises the following steps: a cooperative control unit is logically
independent, and when the situation in the area changes, it is determined that the
brightness of a lighting module needs to be improved or turned on, and it is determined
that the lighting module is in a trigger state and in a working state; If there is no moving
object in the area where the cooperative control unit is located, or the illumination
brightness does not need to be changed in the current area, or the moving object does not need illumination, it is judged that it is currently in a non-triggered state without changing the illumination state, or a time delay is set to turn off the lighting module, which is in case the moving object is leaving for a short time; If the active object stays within the sensing range, the system will be in a continuous trigger state. In this trigger state, the cooperative control unit sends data of situation change in the area where the cooperative control is located to the master control unit. The master control unit receives and stores the data, predicts the activity track of the moving object, and sends early warning messages to one or more cooperative control units around the activity track. The one or more cooperative control units receiving the early warning message control the lighting modules of the one or more cooperative control units, and if the lighting modules are turned off, they become slightly bright (not fully bright); if the lighting modules are already on or slightly bright, the cooperative control units do not change the state of the lighting modules. As soon as the sensor modules of one or more pre-warned cooperative control units sense the environmental changes in the area where they are located, it is determined that there are moving objects in the area where they are located, and the cooperative control units adjust the lighting modules in a slightly bright state to a fully bright state. The master control unit compiles the lighting rule of the area where each cooperative control unit is located according to the changes and lighting conditions of each area in different time periods sent by each cooperative control unit, so as to improve the accuracy of judging the moving track of the moving object and realize real-time and intelligent lighting control.

"a", "an", "the" and "the" are also intended to include the plural form, unless the context
clearly indicates other meaning.
In Embodiment 1, as shown in Fig.1, the overall system of the present invention is
divided into a master control unit 110 and a plurality of cooperative control units 150,
151, and 153. The master control unit 110 is composed of a communication module 111,
a master processor 112, and a storage module 113. The cooperative control unit 153 is
composed of a communication module 121, a cooperative processor 122, a lighting
module 123, a switch module 124, and a sensor group 125. There is no physical
connection between the master unit 110 and the cooperative control units 150, 151, and
153, and there is no physical connection between the cooperative control units 150, 151,
and 153; The master control unit 110 and the cooperative control unit 153 perform two
way information interaction through the communication module 111/121. There is no
information interaction between the cooperative control units 150, 151, and 153. The
cooperative control unit 153 cannot be directly connected to the external network 100
through the communication module 121, and information can only be transmitted to the
external network 100 by the master control unit 110 .
The sensor 125 of the intelligent lighting system in this example is composed of a human
infrared sensor, an ultrasonic sensor, a sound sensor, and a illumination intensity sensor,
and has the following functions: the infrared sensor senses the position of a human body
and judges whether a person is in the room; Ultrasonic sensor: a switch for judging whether a person enters or leaves a room or a door; Illumination intensity sensor: identify environmental illumination intensity; Sound sensor: assisting other sensors to make comprehensive judgment.
Several kinds of sensors work in cooperation with each other to judge the action of the
user and the external environment and make corresponding adjustments to meet the needs
of user to the greatest extent and provide comfortable lighting experience for user.
In the second embodiment, as shown in fig.2, the signal priority corresponding table of
the main control unit of the present invention. The main purpose of this table is to specify
manual mode and automatic mode; Encoding a signal from the cooperative control unit to
the master control unit when a switch of the lighting device in the vicinity of the
cooperative control unit is turned on or off; Sending '01' when the switch is turned on,
indicating that the lighting module of the cooperative control unit is always on and is not
affected by the sensing result of the sensor module of the master control unit or the
cooperative control unit; Similarly, when the switch is set to the off position, i.e., the
lighting module of the cooperative control unit is always off, and "02" is sent at the same
time; When the switch is set to the automatic position, the data "00" is sent, and the
cooperative control unit is in the automatic mode and is controlled by the sensor states of
the master control unit and the cooperative control unit.
When that switch is not in the automatic gear, the sensor of the cooperative control unit is
still working, and data is still being sent to the main control unit after sense the existence
of a user for recording the user data and predict the user behavior, but the sensing result
does not affect the work of the lighting module of the cooperative control unit.

invention shows in fig.3.
Step 301: After the main control unit is powered on, the communication module will be
initialized first, i.e., the entire communication system is established and a channel is
opened;
Step 302: Draw a room association table, wherein the room is each different cooperative
control unit, and the relative relationship among them, for example, the corridor entering
the door and the living room is the association relationship, and the corridor entering the
door is not connected with the bedroom, so they are not of the association relationship,
and the association relationship is used for predicting. If the user enters the corridor, the
user is predicted to move toward the living room, so that the illumination of the living
room is pre-lighted, instead of the predicting the user moving toward the bedroom;
Step 303: Start to cyclically receiving the data from cooperative unit and external;
Step 304: Judging whether a sensor is triggered or not, if not, continue to monitor data,
and if yes, the process proceeds to step 305;
Step 305: Store that data;
Step 306: Predict the user' s path and draw its position according to the transmitted data;
Step 307: The information is sent to the cooperative control unit to which the user may
go, and the preheating of the lighting module is performed;
Step 308: Shutdown operation after receiving an end instruction from the outside,
otherwise, continue the cyclic receiving of data.

present invention is as below:
Step 401: Start;
Step 402: Perform various initialization operations after the cooperative control processor
is activated, including connecting the network interface with the master control unit, self
checking and the like;
Step 403: Cyclically receiving the information sent by the main control unit and
proceeding to the next step according to the information;
Step 404: Judging the current state, which is divided into two states: the lighting module
is currently currently alight or not; Proceed to step 416 if it is alight; Proceeds to step 405
if it is not;
Step 405: Judging if there is early warning information in the information transmitted
from the main control unit or not. If so, the process proceeds to Step 412, and if not, the
process proceeds to Step 406;
Step 406: Monitor sensor information;
Step 407: Check the sensor group is triggered or not, and if so, the process proceeds to
step 408, if not, the process returns to step 403;
Step 408: Check if the switch module of the cooperative control unit is in the manual
position or not, if so, the process proceeds to step 414, and if not, the process proceeds to
step 409;
Step 409: Turn on the lighting module (on fully bright state);
Step 410: Send the data to master control unit including the current cooperative control
name, sensor group status, lighting module status, switch status, etc;
Step 411: Judging if there is an end instruction. If there is, the process proceeds to step
418. If there is no, the process returns to step 403;
Step 412: The lighting module is changed to a slightly bright mode (not fully bright state);
Step 413: It is determined whether the sensor group is triggered or not, if so, the process
proceeds to step 408. If not, the process returns to step 403;
Step 414: It is determined whether the switch module of the cooperative control unit is in
the manual opening position or not. If it is, the process proceeds to step 418, and if not,
the process proceeds to step 415;
Step 415: The lighting module turns into a fully off state;
Step 416: It is determined whether the sensor group is triggered, and if so, the process
returns to step 403. If not, the process proceeds to step 417;
Step 417: The lighting module is turned off after the setting for a period of time, and the
lighting module at this time is considered to be in the off state;
Step 418: End.
Embodiment 5, a first embodiment of the present invention is shown in fig.5, which is a
top view of a general home room. In this system, a main control unit is used, which is
composed of a single chip microcomputer stm32f4504, a WiFi module 505, and an
external memory 506; Three cooperative control units including 501, 502, and 503, which
are cooperative control units 1, 2, and 3 respectively. The cooperative control unit 1(501)
consists of a singlechip stm32fl507, a WiFi module 508, an infrared module 509, an
ultrasonic module 1510 (position 524 is marked in the schematic diagram due to special
position, the same below), an ultrasonic module 2511 (position 525 in the schematic
diagram) and an illumination module 512; The cooperative control unit 2(502) is
composed of a singlechip stm32fl513, an infrared module 515, a sound module 516 and
an illumination module 517; The cooperative control unit 3(503) is composed of a single- chip stm32fl519, an infrared module 520, a photosensitive module 521, a sound module
522, and an illumination module 523.
Since the main control unit 504 can be placed in any position, a specific position is not
marked in the drawing. The scenario is described below:
First, the master control unit 504 performs networking, and accesses all cooperative
control units 501, 502, and 503 to the network for various initialization preparations;
Performing first communication between a master control and a cooperative control after
initialization, and checking the states of each cooperative control unit including whether a
manual mode is set, whether the current sensor of each cooperative control unit works
normally, whether an illumination module works normally and the like; After everything
is ready, enter the standby mode, and wait for the sensor group of the cooperative control
unit to be triggered.
At this time, there is no one in the whole room, so all room lighting facilities are off.
When someone enters through the gate 526, the ultrasonic module 1524 is firstly
triggered, and at the same time, the infrared module 509 of the control unit 501 detects
that someone has entered; After two sensors simultaneously sense that there is an entry,
the cooperative control unit 501 turn on the lighting module 512 according to the current
time (assuming it is night) and the environment, and sends the information to the master
control unit 504 at the same time; The master control unit sends the early warning
information to the cooperative control units 502 and 503 after analysis and prediction, so
that the lighting modules 517 and 523 light up slightly and record the message in the user
database for composing the user habit list.
If no detected next action of the user, the cooperative control units 502, 503 will turn off
the slightly lit lighting module after a period of time; If the user enters the door 529, the
distance change is detected by the ultrasonic sensor 1524 and the sensing is lost from the
infrared module 509 of the cooperative control unit 1, and the message is sent to the main
control unit 504; The main control unit 504 alerts the cooperative control unit 3503 again,
and when the infrared module 520 and the sound module 522 of the cooperative control
unit 503 simultaneously detect that an object enters, the lighting module 523 is adjusted
from slightly bright to fully bright, and at the same time, the lighting module 512 of the
cooperative control unit 1501 enters the off countdown. The same is true when the user
enters 528 and returns to the vicinity of cooperative control unit 501
. If it is daytime at present, it is judged whether it is a cloudy day according to the data
collected by the photosensitive module 521, and uploaded to the main control unit 504 for
judging whether a light is required.
The main control unit can predict the user movement according to the recorded user data.
For example, if a user arrives home between 9: 00 p.m - 9: 30 p.m on a working day, the
main control unit will control the lighting unit of the cooperative control unit 501 to be
slightly lighted during this period, and turns to fully bright mode after detecting an
entrance; For example, a user only enters the room 529 normally when he/she is alone at
home, therefore, when it is detected that the user leaves the room 529, the light in the
room 528 is not to be turned on slightly, and only the light in the room in which the
cooperative control unit 501 is located and the light in the room 527 are notified to be
turned on slightly.
Embodiment 6, a second embodiment of the present invention is shown in fig.6, which
illustrates an application example of a warehouse. In this example, the basic structure of
the master control unit and cooperative control unit is the same as that in example 5,
except that the sensors used are slightly different, which will not be described in detail
here. In fig.6, 601 and 602 are two gates for entering the warehouse, and 603-610 are
cooperative control units.
When there is no one in the warehouse, all the lighting modules of the cooperative
control units are in the off state. The lighting modules of 603, 605, and 606 will be
lighted after detecting someone opens the door of 601 or 602, and the master control unit
is informed of that regardless it is daytime or night. There is no lighting problem in the
closed warehouse in this case, so the lights are turned on when someone enters. The
lighting module of the cooperative control unit to which the predicted path belongs is
lighted when the cooperative control unit 603 or 606 detects the entrance of person or
vehicle.
In this scene, it can be supplemented with the warehouse inquiry system, that is, when the
goods to be found are searched, the navigation road is formed with lights, and the lights
of the path from the personnel's position to the front of the shelf are turned on, while the
lights in other places remain turned off.
The above-mentioned embodiments are only for describing the preferred embodiments of
the present invention and are not intended to limit the scope of the present invention. On
the premise of not departing from the design spirit of the present invention, various
modifications and improvements made to the technical scheme of the present invention by those of ordinary skill in the art should fall within the protection scope determined by the claims of the present invention.
