[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0034] Reference Figures 1 to 7 As shown, the utility model provides an intelligent building lighting system, comprising:

[0035] A data acquisition unit 1, a lighting control unit 2, a cloud server 3, and a mobile device 4 establishing data communication with the cloud server 3;

[0036] and a gateway module 5, the gateway module 5 comprising a coordination unit 51 and a communication unit 52 connected to the coordination unit 51;

[0037] Among them, the data acquisition unit 1 and the lighting control unit 2 are both wirelessly connected to the coordination unit 51, the lighting control unit 2 includes a touch panel switch circuit 21, multiple lamp controller circuits 22 and lighting fixtures 23, the touch panel switch circuit 21 is wirelessly connected to the coordination unit 51, the coordination unit 51 is wirelessly connected to the multiple lamp controller circuits 22, the lamp controller circuit 22 is connected to the lighting fixtures 23, and the communication unit 52 is wirelessly connected to the cloud server 3.

[0038] Preferably, in this embodiment, the coordination unit 51 is a Zigbee CC2530 coordinator, and the communication unit 52 is an ESP8266 WiFi module. In addition, the lighting system further includes a router 6, and the communication unit 52 is wirelessly connected to the cloud server 3 through the router 6.

[0039] In this embodiment, if Figure 2As shown, the data acquisition unit 1 includes a first CC2530 terminal device 11, a temperature and humidity sensor 12 and a light intensity sensor 13. The first CC2530 terminal device 11 is provided with a first data acquisition port 111, a second data acquisition port 112 and a serial clock pin 113. The temperature and humidity sensor 12 is connected to the first CC2530 terminal device 11 through the first data acquisition port 111, and the light intensity sensor 13 is connected to the first CC2530 terminal device 11 through the second data acquisition port 112 and the serial clock pin 113. The first CC2530 terminal device 11 is wirelessly connected to the coordination unit 51.

[0040] When the temperature, humidity and light intensity collector is powered on, the first CC2530 terminal device 11, the AM2303 temperature and humidity sensor 12 and the BH1750 light intensity sensor 13 start working. The first CC2530 terminal device 11 runs the Z-Stack protocol stack. In the temperature, humidity and light intensity collector, the first CC2530 terminal device 11 plays the role of a terminal device, so the software configuration option selects the terminal device. After the Z-Stack software system is executed, the chip becomes a terminal device. Then the first CC2530 terminal device 11 scans the specified channel and joins the network established by the Zigbee CC2530 coordinator. After successfully joining the network, the first CC2530 terminal device 11 initializes the first data acquisition port 111, the second data acquisition port 112 and the serial clock pin 113 (corresponding to the temperature and humidity sensor 12 and the light intensity sensor 13) connected to the temperature and humidity sensor 12 and the light intensity sensor 13. Figure 2 The pins 14, 18 and 19 of the first CC2530 terminal device 11 are connected to the Zigbee network, and then the corresponding temperature, humidity and illumination data transmitted by the AM2303 temperature and humidity sensor 12 and the BH1750 illumination sensor 13 are periodically read through these ports. Then, the data is sent to the Zigbee CC2530 coordinator through the Zigbee network in a specified format. The Zigbee CC2530 coordinator sends the temperature, humidity and illumination data plus the building partition number to the communication unit 52 through the serial port. The communication unit 52 forwards the data to the cloud server 3 through the router 6 using the MQTT protocol. The cloud server 3 publishes the temperature, humidity and illumination data to the mobile device 4 (such as the user's mobile phone APP) through the corresponding building partition number topic. The user can see the temperature, humidity and illumination data of the current building partition number through the mobile device 4.

[0041] Specifically, refer to Figure 3As shown, the touch panel switch circuit 21 includes a plurality of touch panel switches 211, a control chip 212 and a second CC2530 terminal device 213. The control chip 212 is provided with a plurality of key state detection pins 2121 and a synchronous serial interface 2122. The touch panel switch 211 is connected to the control chip 212 via the key state detection pins 2121, and the control chip 212 is connected to the second CC2530 terminal device 213 via the synchronous serial interface 2122. The second CC2530 terminal device 213 is wirelessly connected to the Zigbee CC2530 coordinator. In this embodiment, the control chip 212 is preferably a BS83B08A-3 single chip microcomputer.

[0042] When the touch panel switch circuit 21 is powered on, the BS83B08A-3 single chip microcomputer and the second CC2530 terminal device 213 (i.e. Figure 3 The Zigbee CC2530 terminal device in the BS83B08A-3 microcontroller starts to execute the initialization instruction and turns on the multiple touch panel switches 211 (corresponding to Figure 3 The touch keys K1, K2, K3 and K4 in the BS83B08A-3 microcontroller correspond to the multiple key state detection pins 2121 (in Figure 3 Specifically marked as pin 1, pin 2, pin 3 and pin 4) are set as touch sensing input ports, enabling the internal synchronous serial interface 2122 (corresponding to Figure 3 The BS83B08A-3 microcontroller pins 12, 14 and 16 are configured to work in the host mode. The BS83B08A-3 microcontroller monitors the touch sensing input port. When the user presses the touch button K1, K2, K3 or K4, the BS83B08A-3 microcontroller can identify which button the user has pressed, and then send the corresponding touch button number to the connected Zigbee CC2530 terminal device through the synchronous serial interface.

[0043] Zigbee CC2530 terminal device also starts working after power-on. The CC2530 chip plays the role of terminal device in the touch panel switch. The Z-Stack software system executes the terminal device configuration option, and then the CC2530 chip becomes a CC2530 terminal device. Then the CC2530 terminal device scans the specified channel and joins the network established by the Zigbee CC2530 coordinator. After successfully joining the network, the CC2530 terminal device initializes the internal SPI port (corresponding to pins 14, 15 and 13 of the Zigbee CC2530 terminal device) and configures the SPI port to work in slave mode. In this way, when connectors J1 and J2 are connected, the SPI port of the BS83B08A-3 microcontroller working in the host mode can send touch key number data to the SPI port of the CC2530 terminal device working in the slave mode. When the CC2530 terminal device receives the data, it sends the data to the Zigbee CC2530 coordinator through the Zigbee network. The Zigbee CC2530 coordinator sends the touch button number data to the LED light controller in the current Zigbee network. The LED light controller implements scene control of the LED light according to the touch button number data and lights up the corresponding touch panel button indicator light (D1, D2, D3 and D4 light-emitting diodes in the touch panel switch circuit) according to the current LED light scene. At the same time, the Zigbee CC2530 coordinator sends the touch button number data plus the building partition number to the ESP8266 WiFi module through the serial port. The ESP8266 WiFi module forwards the data to the cloud server 3 through the router 6 using the MQTT protocol. The cloud server 3 forwards the scene data content corresponding to the LED light to the user's mobile phone APP through the corresponding building partition number topic, and the user can see the LED light scene of the current building partition number.

[0044] Reference Figures 4 to 6 As shown, the gateway module 5 further includes a plurality of dip switches 53, and the first receiving data input pin 511 (ie Figure 4 The serial port CC_RX in the communication unit 52 is connected to the second data transmission output pin 521 (i.e. Figure 5 The first data transmission output pin 512 (ie, Figure 4 The serial port CC_TX in the communication unit 52 is connected to the second receiving data input pin 522 (i.e. Figure 5 The serial port W_RX) in the .

[0045] When the gateway module 5 is powered on, the ESP8266 WiFi module and the Zigbee CC2530 coordinator work simultaneously. The ESP8266 WiFi module starts to execute the internal MCU instructions to initialize the serial ports W_TX and W_RX, set the serial port baud rate to 115200bps and other parameters, and then connect to the WiFi router of the network transmission layer according to the specified username and password. After successfully connecting to the router, it periodically sends a handshake request frame in a specified format to the Zigbee CC2530 coordinator through the serial port W_TX pin, and then monitors the serial port W_RX pin to see if there is a CC2530 coordinator handshake response frame in a specified format. If no response frame is received, continue to monitor. If a response frame is received, parse the building partition number in the response frame and stop periodically sending handshake request frames. Then connect to the cloud server 3 of the smart building through the MQTT protocol, so that the devices at the sensor layer and the user's mobile phone APP can subscribe to and publish related topics, and the gateway corresponding to the building partition number can serve as a communication bridge to enable them to communicate with each other.

[0046] The Zigbee CC2530 coordinator also starts working after powering on. The Zigbee CC2530 coordinator runs the Z-Stack protocol stack. Z-Stack is a round-robin query-based operating system. The system first initializes various modules of the chip hardware such as the system clock, initializes the hardware driver, etc., and then initializes various modules of the software architecture such as initializing the MAC layer protocol, etc., and finally initializes the operating system and executes it. In the gateway module 5, the CC2530 chip plays the role of a coordinator, so the configuration option of the software selects the coordinator function. After the operating system is executed, the chip is used as a coordinator in the circuit system. The main function of the CC2530 coordinator is to establish and start the Zigbee network, and receive the terminal devices of the data acquisition unit 1, the touch panel circuit 21, and the lamp controller circuit 22 to access the Zigbee network. After the CC2530 coordinator successfully establishes the network, the serial ports CC_RX and CC_TX are initialized, the serial port baud rate is configured to 115200bps and other parameters, and the CC_RX pin of the Zigbee CC2530 coordinator is connected to the W_TX pin of the ESP8266 WiFi module through the dial switch 53, and the CC_TX pin of the Zigbee CC2530 coordinator is connected to the W_RX pin of the ESP8266 WiFi module, so that the Zigbee CC2530 coordinator and the ESP8266 WiFi module can achieve serial communication. In addition, the serial port CC_RX pin of the CC2530 coordinator also has the function of real-time monitoring whether a handshake request frame of a specified format has arrived. If the serial port CC_RX receives a request frame, the CC2530 coordinator replies a handshake response frame of a specified format to the ESP8266 WiFi module through the serial port CC_TX pin, and the building partition number is pre-configured in the response frame. Accordingly, the wireless module inside the CC2530 coordinator can monitor the network access requests of other terminal devices. Once the terminal device is connected to the network, the coordinator and the terminal device can communicate through the Zigbee network.

[0047] In this embodiment, if Figure 7 As shown, the lamp controller circuit 22 includes a third CC2530 terminal device 221 , and the third CC2530 terminal device 221 is provided with a PWM output control port 2211 , and the PWM output control port 2211 is connected to the lighting fixture 23 , and the third CC2530 terminal device 221 is wirelessly connected to the coordination unit 51 .

[0048] When the lamp controller circuit 22 is powered on, the third CC2530 terminal device 221 (i.e., the Zigbee CC2530 terminal device) starts working. In the lamp controller circuit 22, the CC2530 chip plays the role of the terminal device, the Z-Stack software system executes the terminal device configuration option, and then the CC2530 chip becomes the CC2530 terminal device. Then the CC2530 terminal device scans the specified channel and joins the network established by the Zigbee CC2530 coordinator. After successfully joining the network, the CC2530 terminal device initializes the D1 and D3 (pins 9 and 11 of the Zigbee CC2530 terminal device) light-emitting diode indicator ports as output ports, initializes the LED light control pin (pin 7 of the Zigbee CC2530 terminal device) as a PWM output control port, and configures the output frequency of the PWM port to 1KHz. Then the CC2530 terminal device sends the current LED light scene data to the Zigbee CC2530 coordinator through the Zigbee network approximately every 30 seconds. The Zigbee CC2530 coordinator adds the LED light scene data to the building partition number and sends it to the ESP8266 WiFi module through the serial port. The ESP8266 WiFi module forwards the data to the cloud server 3 through the router using the MQTT protocol. The cloud server 3 forwards the scene data content corresponding to the LED light to the user's mobile phone APP through the corresponding building partition number topic. The user's mobile phone APP can refresh the current LED light scene interface. At the same time, the wireless module inside the CC2530 terminal device monitors the button number data from the CC2530 coordinator: when the user presses the LED light scene button on the mobile phone APP, the button number data of the mobile phone APP will be forwarded to the CC2530 coordinator through the cloud server 3, the router and the ESP8266 WiFi module; when the user presses the touch button on the touch panel, the button number data of the touch panel will be forwarded to the CC2530 coordinator through the Zigbee network. After the CC2530 coordinator receives the button number data on the mobile phone APP or touch panel, it will send it to the CC2530 terminal device that monitors the button number data reception. When the CC2530 terminal device receives the LED light scene button data, it will execute the corresponding button scene function.

[0049] For example, when receiving the daily scene button data, the PWM port output duty cycle is adjusted to 100%, that is, the LED light brightness level is the highest, and the D1 and D3 indicators are on; when receiving the movie scene button data, the PWM port output duty cycle is adjusted to 60%, that is, the LED light brightness level is second, the D1 indicator is always on, and the D3 indicator flashes at a frequency of 1Hz; when receiving the meditation scene button data, the PWM port output duty cycle is adjusted to 30%, that is, the LED light brightness level is third, the D1 indicator is always on, and the D3 indicator flashes at a frequency of 0.5Hz; when receiving the leaving home scene button data, the PWM port output duty cycle is adjusted to 0%, that is, the LED light is turned off, and the D1 and D3 indicators are off. In this way, the user's mobile phone APP or touch panel button can realize the scene control of the LED light.

[0050] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
