Fig. 1 shows a schematic block diagram of a luminaire control arrangement 100 according to a first exemplary embodiment of the present invention. The luminaire control device 100 may comprise a control circuit 101, a communication interface 102 and a MCU 103. In some embodiments, control circuit 101, communication interface 102, and MCU103 may be disposed on a luminaire control circuit board.
The control circuit 101 may be connected to a luminaire (not shown) and configured to control switching and/or dimming of the luminaire. For example, the control circuit 101 may include a driving circuit for performing a switching operation on the lamp and a dimming circuit for dimming the lamp.
The communication interface 102 is capable of physically connecting and communicating data with a communication device. The communication device may be a wireless communication device, such as a bluetooth device, Zigbee device, Wi-Fi device, PLC-IoT device, and may be disposed on a different circuit board than the luminaire control circuit board to enable the communication device to be removably connected with the luminaire control device. The communication device may send the instruction data to the communication interface 102 using a predetermined data format.
The MCU103 is connected to the communication interface 102 and configured to receive instruction data from the communication device from the communication interface 102 to perform a corresponding operation according to instruction contents in the instruction data. In some embodiments of the present invention, the operation may include manipulating the control circuit to control switching or dimming of the light fixture, and may further include sending feedback data to the communication device via the communication interface 102 using a predetermined data format. The feedback data may comprise information such as the status of the luminaire. The state of the light fixture may include on-off state, brightness, contextual mode, and reset. The MCU103 can monitor the light fixtures (real-time or on-demand) to obtain the status of the light fixtures. For example, the MCU103 can sample the switch state of the lamp from the power input of the lamp. The control program of the lamp can be written into the MCU103 so that the MCU103 can control the control circuit 101 (for example, including the LED driving circuit and the dimming circuit), and realize the functions of switching the lamp, dimming, and color tuning.
In this way, the command data and the feedback data may have a uniform data format, so that the communication modules with different communication protocols and the lamp control device 100 communicate with each other by using a uniform data protocol.
In the embodiment of the present invention, an innovative data protocol is designed for the communication between the MCU103 in the luminaire control device 100 and the external communication device. Fig. 2 shows an example of a preset data format, which may include a Header field (which may be referred to as a "Header" field), a Length field (which may be referred to as a "Length" field), a Payload field (which may be referred to as a "Payload" field), a check field (which may be referred to as a "CheckSum" field), and an End field (which may be referred to as an "End" field). The "Header" field may be set to fixed data as a start identifier. The "Length" field may be used to identify the total Length of the "Payload" field. The "Payload" field may include critical instruction Data and, in some examples, may include a "Type" subfield and a "Data" subfield, where the instruction content may be contained in the "Data" subfield and the "Type" subfield may be used to represent an identifier of the Type of instruction (i.e., Data within the "Data" field), such as on-off, brightness, color temperature, and reset, etc. The "CheckSum" field may be used to check the data, for example, to compute a CheckSum from the "Length" field to the "Payload" field. The "End" field may be set to fixed data as an End identifier. Note that the data protocol definition of the present invention is not limited to the manner illustrated in fig. 2, and those skilled in the art can conceive various protocol definition manners based on the inventive concept of the present invention.
Optionally, when the instruction content in the instruction data received by the MCU103 indicates a distribution network success prompting instruction or a status query instruction, the MCU103 may detect the status of the lamp and send feedback data to the communication module to inform the status of the lamp.
Alternatively, when the instruction content in the instruction data received by the MCU103 represents a control instruction, the MCU103 may perform a corresponding control operation (e.g., switching on or off or dimming), and may send feedback data to the communication module to inform the current state (i.e., the changed state) of the lamp after the corresponding control operation is completed.
Optionally, before the MCU103 performs the corresponding control operation, the MCU103 may send back a reply data to the communication module, and the reply data may represent the control operation to be performed by the MCU103 and have a unified data format with the command data and the feedback data. Thus, the communication module can know whether the MCU103 correctly receives the control command.
Alternatively, when the state of the luminaire changes (e.g., physical switch operation or power-off restart), the MCU103 may actively transmit feedback data containing the current state of the luminaire to the communication module.
The above describes a luminaire control apparatus according to an exemplary embodiment of the present invention. Different from the traditional intelligent lamp control system, the lamp control device is not integrated with a specific communication device, but can communicate with various wireless communication devices in an external connection mode, and data transmission is carried out on the communication devices of various technologies and the lamp control MCU according to a unified data protocol through the unified data protocol between the communication device and the lamp control MCU, so that the compatibility and seamless switching between the lamp control device and various communication modules can be realized.
Fig. 3 shows a schematic block diagram of a system 300 for controlling a luminaire according to a second exemplary embodiment of the present invention. System 300 may include a luminaire control device 310 and a communication device 320. The luminaire control device 310 may comprise a control circuit 311, a communication interface 312 and an MCU 313. Most of the details of the luminaire control device 310 in the system 300 according to the second exemplary embodiment are the same as the luminaire control device 100 according to the first exemplary embodiment, and are not described herein again. The following mainly describes the communication device 320.
The communication device 320 may include a wireless communication module 321 and a communication connector 322. The wireless communication module 321 may communicatively connect with a remote device over a wireless communication protocol (such as bluetooth, Zigbee, Wi-Fi, PLC-IoT) to receive command signals from the remote device or to send feedback signals to the remote device. Upon receiving the command signal from the remote device, the wireless communication module 321 may parse the command signal into command data using a preset data format for use by the luminaire control apparatus 310 (specifically, the MCU 313). Alternatively, upon receiving feedback data having a preset data format from the luminaire control device 310 (specifically, the MCU 313), the wireless communication module 321 may convert the feedback data into a feedback signal for transmission to the remote device through the wireless communication protocol.
The communication connector 322 may be adapted with the communication interface 312 of the luminaire control arrangement 310 to enable transmission of instruction data from the wireless communication module 321 to the communication interface 312 and transmission of feedback data from the communication interface 312 to the wireless communication module 321. For example, the communication interface 312 of the luminaire control device 310 may be in the form of a socket, and the communication connector 322 of the communication device 320 may be in the form of a pin, which may be engaged for physical connection and data communication.
Unlike the conventional intelligent lamp control system, the lamp control device 310 and the communication device 320 according to the present invention are not integrated and may be respectively disposed on different PCB boards, and the lamp control program is not written in the communication device but is written in the independent MCU313 of the lamp control device 310. In this way, the lamp control is not affected by the communication device 320, but is implemented by the independent MCU313 of the lamp control device 310, and the lamp control device 310 and the communication device 320 exchange data using a unified data protocol (i.e., a preset data format), so that the lamp control device 310 can be compatible with and seamlessly switch with a wide variety of communication devices 320 using different wireless communication protocols. The communication device 320 may be a wireless communication device such as a bluetooth device, a Zigbee device, a Wi-Fi device, a PLC-IoT device, or the like. The communication device 320 may transmit instruction data to or receive feedback data from the communication interface 312 using a predetermined data format.
As an example, referring to fig. 4, the luminaire control device 310 may be disposed on a luminaire power supply circuit board, which may include a power input, control circuitry (including dimming circuitry, LED drive circuitry, and a connector to an LED module), an MCU module (including an MCU luminaire control circuitry, an MCU power supply circuitry), and a communication interface (i.e., a communication module socket or connector) when the luminaire is an LED. The communication device 320 may be disposed on a communication circuit board, which may include a wireless communication chip, a wireless transceiver antenna (on-board or wired), a communication module pin. The control program of the LED lamp can be written in the MCU on the power circuit board, and the on-off state of the LED is sampled and detected from the power end of the LED; and the LED driving circuit and the dimming circuit on the power circuit board are controlled, and the functions of switching on and off, dimming, color mixing and the like of the lamp are realized. When the communication module socket is connected with the communication module contact pin, the MCU lamp control circuit can exchange data with the communication module circuit, and obtain an external control instruction or feed back the state of the LED lamp to the communication module in a uniform preset data format; and the communication module is specially responsible for receiving and transmitting external wireless instructions, exchanges data with the MCU lamp control circuit, transmits the external instructions to the MCU circuit in a uniform preset data format and acquires feedback data of the MCU.
In the following, an example of the operating logic of a system for controlling a luminaire according to an embodiment of the present invention will be described. It will be appreciated that the present invention is not limited to such an operating logic and that alternative operating logic flows may be devised in accordance with the inventive concepts described above.
Fig. 5, 6, and 7 are schematic diagrams of network distribution, control, and active reporting interaction flows for the system 300 of fig. 3, respectively. Fig. 8 shows an example of communication data between the MCU and the external communication device. In this example, the Header field is designed to be 2 bytes and has a fixed value of 0x5A,0xA 5; the Length field is designed to be 1 byte to identify the total Length of the Payload field (without the CheckSum field and the End field). The CheckSum field is designed to be 1 byte for Cyclic Redundancy Check (CRC). The End field is designed to be 1 byte with a fixed value of 0 xAA.
As shown in fig. 5, when the wireless communication module 321 receives a distribution network instruction from a remote device, the communication module 321 establishes pairing with the remote device, and generates instruction data representing a distribution network success prompting instruction according to a preset data format after the pairing is successful and transmits the instruction data to the MCU313 via the communication connector 322 and the communication interface 312. When the instruction content in the instruction data received by the MCU103 indicates a distribution network success prompting instruction, the MCU103 may enter a remote control mode to wait for a control instruction and simultaneously turn on a state reporting function. For example, when the instruction content in the instruction data subsequently received by the MCU103 indicates a distribution network success prompting instruction or a status query instruction, the MCU103 may detect the status of the lamp and send feedback data to the communication module to inform the status of the lamp.
As shown in fig. 6, when the wireless communication module 321 receives an instruction signal representing a control instruction from a remote device, the wireless communication module may generate instruction data representing a corresponding control operation according to a preset data format and transmit the instruction data to the MCU313 via the communication connector 322 and the communication interface 312. As shown in fig. 8, such control instructions may include a switch reversal instruction, a brightness adjustment instruction, or a context mode adjustment instruction. In the brightness adjustment instruction Data, the second byte 01 in the Data field represents an increase in brightness, 00 represents a decrease in brightness, and 02 represents a brightness percentage setting; the third byte represents a gear value of the change in brightness when the brightness is increased or decreased, and represents a specific numerical value of the percentage when the brightness percentage is set. In the contextual model instruction Data, the second byte in the Data field represents a specific contextual model number, 01 represents a model one, and so on. When the instruction content in the instruction data received by the MCU103 represents a control instruction, the MCU103 may perform a corresponding control operation (e.g., switching on or off or dimming), and may send feedback data to the communication module to inform the current state (i.e., the changed state) of the lamp after the corresponding control operation is completed. When the wireless communication module 321 receives feedback data from the MCU313, the wireless communication module 321 sends a feedback signal to the remote device indicating the status of the light fixture. As shown in fig. 6, the MCU313 may also send a reply data back to the communication module 321, which may represent the control operation to be performed by the MCU313 and also follow a preset data format, before the MCU313 performs the corresponding control operation. The communication module 321 can know whether the MCU103 correctly receives the control command or correctly performs the operation according to the received reply data. If the reply data is not received (i.e., indicating that the MCU103 has not correctly received the control command or has not correctly performed the operation), the communication module 321 may again transmit the previous command data. If reply data is received (i.e., indicating that the MCU103 correctly received the control command or correctly performed the operation), the wireless communication module 321 may transmit acknowledgement (ack) data to the MCU313, the acknowledgement data also following the preset data format, as shown in fig. 8. When the wireless communication module 321 receives the feedback data from the MCU313, the wireless communication module 321 may also transmit acknowledgement (ack) data to the MCU 313.
As shown in fig. 7, when the MCU313 actively detects that the status of the lamp changes (for example, a physical switch operation or a power-off restart), the MCU313 may actively report the active status, that is, actively send feedback data including the current status of the lamp to the communication module 321. When the wireless communication module 321 receives the feedback data from the MCU313, the wireless communication module 321 may transmit acknowledgement (ack) data to the MCU313 and transmit a feedback signal representing the status of the luminaire to the remote device.
In the above example, status reporting (i.e. sending feedback data) may be divided into passive reporting and active reporting, and the triggering mechanism may be: (1) when the MCU receives the control instruction, the changed state is sent to the communication device through state reporting after the corresponding control operation is correctly executed; (2) the MCU actively monitors the state change of the lamp and sends the changed state to the communication device; and (3) when the MCU receives the lamp state query instruction, the MCU sends the lamp state to the communication device. The status reporting (i.e. sending feedback data) may be an asynchronous processing protocol, and if the MCU does not receive status reporting response data within a specified time or the status in the received reporting response data is unsuccessful, the MCU may report the status again.
It is noted that fig. 6-8 depict only examples of design concepts according to the present invention and are not intended to limit the scope of the present invention.
Thus far, a luminaire control arrangement and a system for controlling a luminaire according to the present invention have been described. The invention has the advantages that: 1) the lamp control circuit and the MCU are designed on the same power circuit board, and the communication module is arranged on the other communication circuit board, so that the intelligent (remote control) and non-intelligent sharing of one PCB (namely, the power circuit board) can be realized; 2) the lamp control program is separated from the communication module, the intelligent lamp control program is written in the independent MCU and is designed on the lamp power circuit board, so that the problem that the lamp control is not influenced by the communication module is solved, the lamp control program is designed at one time and is utilized for multiple times later; 3) the communication device is only responsible for receiving and transmitting wireless signals, analyzing and converting the wireless signals into a uniform preset data format and transmitting the uniform preset data format to the MCU of the lamp power supply, so that the problem that various communication modules are repeatedly designed to adapt to lamp control programs is solved; and 4) through designing a unified data protocol between the communication modules of various different technologies and the control MCU on the lamp power supply, seamless switching between the communication modules and the lamp control MCU is realized, and the plug and play is realized.
