a main control module 12, including a main control processor, connected to the bus module and the bus control module, respectively, for outputting a first control signal and a lamp control signal to the bus module, receiving a lamp feedback signal through the bus module, and sending a second control signal to the bus control module; it should be noted that the main control module may further include other functional circuits, and components such as a power supply for supplying power to the main control processor and other circuits;

Specifically, the main control processor may be a general-purpose Central Processing Unit (CPU), an Application Specific Integrated Circuit (ASIC), a Micro Control Unit (MCU) MCU, or one or more Integrated circuits for controlling program execution.
Further, the luminaire control circuit may further include a memory, and the number of the memories may be one or more. The Memory may include a Read Only Memory (ROM), a Random Access Memory (RAM), and a disk Memory.
It should be noted that the voltage input end of the bus module may be connected to power supplies such as a mains supply and a storage battery, and the power supply voltage of the power supplies is used to supply power to the downstream-end lamp. That is, the voltage input from the voltage input terminal is necessarily in a high state.
The voltage control unit (including the first voltage control unit and the second voltage control unit) may be a circuit module or an electronic component for adjusting the voltage, for example, an adjustable resistor module, a voltage adjustment module with a capacitor and a resistor connected in parallel, etc., and any device or circuit that can be used to adjust the high-level input voltage to the low-level output voltage may be used as the voltage control unit. Meanwhile, in the technical scheme of the embodiment of the application, whether the high-level input voltage is adjusted to the low-level output voltage can be actually controlled by controlling the on or off of the voltage control unit.
And the main control module can generate a control instruction through the main control processor to realize the on-off control of the voltage control unit. Meanwhile, the main control processor can send control signals to downstream lamps through the bus module and receive feedback signals of the downstream lamps.
Specifically, the main control module in the embodiment of the present application may send a flag indicating whether to output a control signal or to complete sending of the control signal to the downstream lamp by controlling the level and the duration of the level state, respectively, output by the voltage output end, so that the lamp may perform corresponding data transceiving mode switching, and a control function of the circuit in the embodiment of the present application on the lamp is achieved.
Further, the first voltage control unit in the embodiment of the present application includes:
the voltage source circuit comprises a first MOS tube and a first resistor which are connected in parallel, wherein the source of the first MOS tube is connected with one side of the first resistor, the drain of the first MOS tube is connected with the other side of the first resistor, the voltage output end is connected with the grid of the first MOS tube, and the main control module is connected with the grid of the first MOS tube.

the second resistor and the second MOS tube are connected in series, the source electrode of the second MOS tube is connected with the low-level input end, the drain electrode of the second MOS tube is connected with the second resistor, and the grid electrode of the second MOS tube is connected with the main control module.
That is to say, in the embodiment of the present application, on one hand, the first MOS transistor in the first voltage control unit may be controlled to be turned on to enable the voltage output terminal to output a high-level voltage (that is, the first path is in a high-level state), and the first MOS transistor may be controlled to be turned off to enable the voltage output terminal to output a low-level voltage (that is, the first path is in a low-level state). On the other hand, the second MOS transistor in the second voltage control unit may be controlled to be turned on to enable the voltage output terminal to output a low level voltage (that is, the first path and the second path are in a low level state), and the second MOS transistor may be controlled to be turned off to enable the voltage output terminal to output a high level voltage (that is, the first path is in a high level state).
It should be noted that, the bus control module in the embodiment of the present application further includes:
and the bus voltage monitoring module is connected with the other end of the second resistor and is connected with the voltage output end through a third resistor and the triode. Of course, the other end of the bus voltage detection module can be connected with the main control processor, so that the lamp control circuit further has a function of monitoring the voltage state on the bus, and a monitoring result can be sent to the main control processor.
Still further, when the lamp control circuit in the embodiment of the present application is used to transmit data (transmit a code), the main control processor is configured to output the lamp control signals to the at least two lamps through the bus module after continuously transmitting a first turn-off control signal for controlling the first voltage control unit to be in a turn-off state within a first time period.
The first time length can be 5ms, 7ms, 10ms and the like, and can be set according to needs in actual operation.
That is to say, the master control processor continuously sends out control to the first voltage control unit to be in the off state within the first time period, so that the time period for the voltage output end to output the low level is the first time period. The downstream load lamp can be automatically adjusted to a signal receiving mode after judging that a result of the bus module continuously outputting the low level voltage for the first duration is obtained, and receives a lamp control signal sent by the main control module.
Meanwhile, the main control processor is used for outputting high-level lamp control signals to the at least two lamps in the process of continuously sending out first conduction control signals for controlling the first voltage control unit to be in a conduction state; and/or the main control processor is used for outputting low-level lamp control signals to the at least two lamps in the process of continuously sending out the first turn-off control signals.
After the main control module sends a mark to be sent a control signal to a downstream lamp by controlling the on-off state of the first voltage control unit, a high-level lamp control signal can be sent to the downstream lamp by continuously controlling the first voltage control unit to be in a conducting state (continuously making the first passage be in a high-level state). And sending a low-level lamp control signal to a downstream lamp by continuously controlling the first voltage control unit to be in an off state (continuously enabling the first path to be in a low-level state).
The above process is a specific operation means when the lamp control circuit in the embodiment of the present application is used to transmit data (transmit a code).
When the lamp control circuit of the embodiment of the application is used for receiving lamp feedback data (code returning), the main control processor is used for continuously sending a second conduction control signal within a second time period starting when the lamp control signal needing to be fed back is sent, so that the second voltage control unit is in a conduction state, and receiving feedback signals output by the at least two lamps through the bus module within the second time period.
The second time period may be a time period in which the master control processor needs to completely receive the lamp feedback signal. The lamp control signal needing to be fed back may refer to: after receiving the control signal, the lamp needs to send a feedback signal corresponding to the control signal to the main control processor. Further, the main control processor is configured to send a second turn-off control signal to enable the second voltage control unit to be in a turn-off state after data representing stop feedback is obtained through analysis from the feedback signal.
That is, after the main control processor finishes sending the lamp control signal requiring feedback, the second voltage control unit may be continuously controlled to be in the on state (in the embodiment of the present application, M1 may be adjusted to be in the continuously on state), so as to reduce the bus voltage to the low level state (in the embodiment of the present application, the level at the voltage output terminal is one third of the mains voltage when M1 is turned on). When the downstream lamp detects that the voltage output end of the bus module continuously outputs low level and simultaneously analyzes and determines that the received lamp control signal needing to be fed back is received (both conditions need to be met), the downstream lamp starts to output a feedback signal to the bus module, and the main control processor can receive the feedback signal through the bus module.
Further, referring to fig. 3, the BUSdata terminal is used to connect to the voltage output terminal 102 of the bus module. When a downstream lamp in the embodiment of the application needs to send a high-level feedback signal, the triode VT1 may be turned on, at this time, the bus current passes through the resistor R4 to the ground, and since a current is generated at the voltage output end of the bus module, the second resistor and the third resistor generate a voltage drop, the main control processor may detect the voltage at the voltage output end through the bus voltage monitoring module, and calculate and compare to obtain that the feedback signal sent by the downstream lamp is a high-level signal; when the downstream lamp sends a low-level feedback signal, the triode VT1 can be turned off, at this time, the bus current cannot pass through the resistor R4 to the ground, and no current is generated at the voltage output end of the bus module, so that no voltage drop exists at the connection end of the bus voltage monitoring module, the main control processor detects that the voltage drop on the voltage output end is zero, and the data sent by the downstream lamp is low level through calculation and comparison; after the downstream lamp sends the feedback signal (the feedback signal may be a signal of a designated bit number, and whether the feedback signal is received or sent is determined by judging the bit number of the received feedback signal), a data bit identifier is continuously sent as a stop bit, and when the main control processor receives the stop bit, the main control processor controls the second voltage control unit to be in a turn-off state, so that the voltage on the voltage output end is rapidly increased to the working voltage of the lamp, and the normal work of the lamp is ensured.
Therefore, the technical scheme in the embodiment of the application is that through arranging the bus module comprising the first voltage control unit, a bus control module connected with the bus module and including a second voltage control unit, a main control module respectively connected with the bus module and the bus control module, therefore, the level control of the output of the bus module can be realized by controlling the on and off of the first voltage control unit and the second voltage control unit through the main control processor, the output and the receiving of high level signals and low level signals can be finished, the identification signal for starting signal transmission or not can be sent to the downstream lamp, the intelligent automatic control of the downstream lamp can be finished by a small amount of cooperative equipment depending on a simplified wiring mode, meanwhile, the technical scheme of the application adopts a circuit communication mode, and a fast and efficient communication control function can be realized without combining a distribution electric device. Therefore, the lamp control circuit has the technical effects of reducing the production and application cost of the lamp control circuit and improving the safety and the maintenance efficiency of the lamp control circuit.
