[0019] In the related art, due to the timing differences between different control chips, each circuit can only be equipped with the same control chip to ensure the normal transmission of signals inside the lighting device. When other types of control chips need to be added to the circuit, the circuit cannot work properly. For example, the circuit includes control chip A and control chip B. Due to the timing differences between control chip A and control chip B, the signal that meets the timing requirements of control chip A cannot be transmitted to control chip B.
[0020] In order to improve the above-mentioned problems, the present application provides a control device and a control system, the control device comprising: a micro-control module, a channel control module and multiple control modules, wherein: the micro-control module is connected to the channel control module, and the multiple control modules are respectively connected to the channel control module; the micro-control module is used to determine the target transmission channel; the micro-control module is also used to generate a target channel conduction signal according to the target transmission channel, and send the target channel conduction signal to the channel control module; the channel control module is used to determine the target control module among the multiple control modules according to the target channel conduction signal, connect the transmission channel between the channel control module and the target control module, so as to transmit the control signal that meets the timing requirements of the target control module through the target control module, and the control signal is a signal for controlling the working state of any control module among the multiple control modules.
[0021] Therefore, through the mutual cooperation between the micro-control module and the channel control module, the channel between the target control module and the channel control module that meets the control signal timing is connected, so as to realize the flexible determination of the control module according to actual needs to ensure the normal transmission of the control signal and the normal operation of the control module.
[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0023] See also Figure 1 , Figure 1 Schematic diagram of a control device provided in an embodiment of the present application. Figure 1 As shown, Figure 1 The control device 100 includes a micro-control module 110, a channel control module 120 and a plurality of control modules.
[0024] The micro-control module 110 is connected to the channel control module 120 , and the plurality of control modules are connected to the channel control module 120 respectively.
[0025] Among them, the micro-control module 110 is used to determine the target transmission channel; the micro-control module 110 is also used to generate a target channel conduction signal according to the target transmission channel, and send the target channel conduction signal to the channel control module 120; the channel control module 120 is used to determine the target control module among multiple control modules according to the target channel conduction signal, and connect the transmission channel between the channel control module 120 and the target control module to transmit the control signal through the target control module, and the control signal is a signal for controlling the working state of any control module among the multiple control modules.
[0026] In some embodiments, the micro control module 110 may be a micro control unit (MCU). The multiple control modules may be red green and blue LED control chips (RGBIC) of different models.
[0027] In some embodiments, the micro-control module 110 can determine the target transmission channel according to the user's selection. For example, when the user selects control module A among multiple control modules as the target transmission channel, the micro-control module 110 determines control module A as the target transmission channel. In some embodiments, the user can determine, according to the timing parameters corresponding to the control signal, a control module with the same timing parameters corresponding to the control signal among multiple control modules as the target control module.
[0028] After determining the target transmission channel, the micro-control module 110 generates a target channel conduction signal according to the target transmission channel to send the target channel conduction signal to the channel control module 120. The channel control module 120 then selects a channel connected to the target control module according to the target channel conduction signal so that the control signal flows from the channel control module 120 to the target control module. Then, the target control module can determine the corresponding working parameters according to the control signal to control the working parameters required by the functional module connected to the target control module, thereby controlling the functional module to perform the corresponding working operation.
[0029] After the target control module parses the control signal to correspond to the information corresponding to the functional module connected to the target control module, the control signal is sent to the channel control module 120, so that the channel control module 120 sends the control signal to the next control device 100 or other modules of the circuit.
[0030] In some embodiments, the control signal is generated by a main controller. When the target control module receives the control signal, and the control signal includes information for controlling the functional module connected to the target control module, the target control module parses the control signal to determine the working parameters required by the functional module, and sends the working parameters to the functional module, so that the functional module presents a corresponding working state, and then sends the control signal to the channel control module 120.
[0031] Thus, the target transmission channel can be flexibly selected according to actual needs, and then the target control module can be determined according to the target transmission channel, so as to connect the channel control module 120 to the channel for transmission between any control module among the multiple control modules, that is, the channel for transmission from the channel control module 120 to the target control module can be connected according to actual needs, so that the control signal can be transmitted in the target control module that meets the timing requirements. , thereby avoiding the situation where the control signal cannot be transmitted normally or the situation where the control module is abnormal.
[0032] Further, in some embodiments, see Figure 2 , Figure 2 1 is a schematic diagram of the structure of another control device provided by an embodiment of the present application. The control device 100 also includes an input module 130, which is connected to the micro-control module 110, and the input module 130 includes a plurality of channel gears. The input module 130 is used to respond to the user's selection operation of the target channel gear among the plurality of channel gears, and send the information of the target channel gear to the micro-control module 110, so that the micro-control module 110 determines the target transmission channel according to the information of the target channel gear.
[0033] In some embodiments, the input module 130 may be a toggle switch, and the toggle switch includes channel gear 1, channel gear 2, ..., channel gear N. Each channel gear corresponds to a control module in a plurality of control modules. For example, channel gear 1 corresponds to control module A, channel gear 2 corresponds to control module B, and so on. When the input module 130 is in channel gear 1, the micro-control module 110 may determine that control module A is the target transmission channel according to the control module corresponding to channel gear 1.
[0034] In other implementations, the micro-control module 110 may determine, according to the timing parameters corresponding to the transmitted control signal, a control module that satisfies the corresponding timing parameters from among the multiple control modules as a target transmission channel.
[0035] After the micro-control module 110 determines the target transmission channel through the input module 130, the micro-control module 110 generates a target channel conduction signal according to the target transmission channel, and sends the target channel conduction signal to the channel control module 120. Further, in some embodiments, please refer to Figure 3 , Figure 3 is a schematic diagram of the structure of another control device provided in an embodiment of the present application. Figure 2 As shown, the channel control module 120 includes an input unit 121 and an output unit 122, the input unit 121 includes multiple output terminals, the output unit 122 includes multiple input terminals, the input terminals of the multiple control modules are respectively connected to the multiple output terminals included in the input unit 121, the output terminals of the multiple control modules are respectively connected to the multiple input terminals included in the output unit 122, the input terminals of the multiple control modules correspond one-to-one with the multiple output terminals included in the input units, and the output terminals of the multiple control modules correspond one-to-one with the multiple input terminals included in the output units.
[0036] In some embodiments, the input unit 121 is a one-input multiple-output switch, and the output unit 122 is a multiple-input one-output switch.
[0037] Among them, the input unit 121 sets the output end of the input unit 121 corresponding to the target control module to the first level, and the output unit 122 sets the input end of the output unit 122 corresponding to the target control module to the second level, so that the output end of the input unit 121, the target control module and the channel where the input end of the output unit 122 is located are connected.
[0038] In some implementations, the first level and the second level are the same level, and the first level and the second level are high level or low level. It is understandable that the first level and the second level can also be opposite levels, which can be flexibly adjusted according to specific circumstances.
[0039] Exemplarily, the target channel conduction signal sent by the micro-control module 110 to the input unit 121 and the output unit 122 includes control module A as the target control module. The input unit 121 will set the level of the output end corresponding to the control module A to 1 according to the target channel conduction signal, and the output unit 122 will set the input end corresponding to the control module A to 1 according to the target channel conduction signal, so as to open the channel where the output end corresponding to the control module A, the control module A and the input end corresponding to the control module A are located, so as to pass the control signal to the control module A, and transmit the control signal to the next control device 100 or other modules through the input end corresponding to the control module A.
[0040] In some embodiments, see Figure 4 , Figure 4 Schematic diagram of the structure of another control device provided in the embodiment of the present application. Figure 4 As shown, the control device 100 also includes a main controller 140, which is connected to the channel control module 120; the main controller 140 is used to receive control instructions from the mobile terminal, generate control signals according to the control instructions, and send control signals to the channel control module. Among them, the control instructions may include instructions for controlling the working state of the control module on the control device 100.
[0041] Exemplarily, the output end of the main controller 140 is connected to the input unit 121, the main controller 140 generates a control signal according to the control instruction, the main controller 140 transmits the control signal to the input unit 121, the input unit 121 and the output unit 122 conduct the signal according to the target channel, and then conduct the output end corresponding to the input unit 121, the target control module and the input end corresponding to the output unit 121, so that the control signal can be transmitted in the target control module that meets the control signal timing parameters.
[0042] In some embodiments, see Figure 5 , Figure 5 FIG. 1 is a schematic diagram of the structure of another control device provided in an embodiment of the present application. Figure 5 As shown, the control device 100 further includes a main controller 140 and a slave control module 150 . The main controller 140 is connected to the slave control module 150 or the channel control module 120 , and the slave control module 150 is connected to the channel control module 120 .
[0043] Among them, the slave control module 150 is used to receive the control signal sent by the main controller 140 or the channel control module 120; the slave control module 150 is also used to determine the working parameters according to the control signal to control the working state of the function execution module connected to the slave control module 150 according to the working parameters.
[0044] The slave control module 150 only includes one control module, and the control module in the slave control module 150 is a red green and blue LED control chip (RGBIC).
[0045] Exemplarily, the output end of the main controller 140 is connected to the slave control module 150, and the output end of the slave control module 150 is connected to the input unit 121. The main controller 140 transmits the generated control signal to the slave control module 150, and the slave control module 150 determines the working parameters for controlling the function execution module connected to the slave control module 150 according to the control signal, and then transmits the control signal to the input unit 121. The input unit 121 then transmits the control signal to the target control module, and the target control module determines the working parameters in the control signal for controlling the function module connected to the control signal, and then transmits the control signal to the output unit 122.
[0046] Exemplarily, the output end of the main controller 140 is connected to the input unit 121, and the output end of the output unit 122 is connected to the slave control module 150. The main controller 140 transmits the generated control signal to the input unit 121, and the input unit 121 then transmits the control signal to the target control module, and the target control module determines the working parameters of the function module connected to the control signal in the control signal, and then transmits the control signal to the output unit 122, and the output unit 122 then transmits the control signal to the slave control module 150, and the slave control module 150 determines the working parameters for controlling the function execution module connected to the slave control module 150 according to the control signal.
[0047] In some embodiments, the control device 100 further includes a light module, which is connected to at least one of the multiple control modules, and the at least one control module is used to determine working parameters according to the control signal and send the working parameters to the light module. The light module is used to work according to the working parameters.
[0048] For example, when a control signal is transmitted to a target control module, the target control module determines the working parameters of a lamp module connected to the target control module according to the control signal, and sends the working parameters to the connected lamp module, and the lamp module turns on or off the light of the corresponding color or the corresponding brightness according to the working parameters.
[0049] More specifically, in some embodiments, the lamp module includes at least one lamp unit, the at least one lamp unit is connected in sequence, the first lamp unit of the at least one lamp unit is connected to at least one control module, and the at least one lamp unit is used to work according to the working parameters. Among them, at least one lamp unit is a lamp bead.
[0050] It is understood that the light module can also be connected to the slave control module 150 to determine the working state of the light module according to the working parameters determined by the slave control module 150. In a specific embodiment, see Figure 6 , Figure 6 is a circuit structure diagram of a lamp module provided in an embodiment of the present application. Figure 5 As shown, the slave control module 150 adopts a three-way RGB control chip (in other embodiments, the slave control module 150 adopts a four-way RGB control chip, a five-way RGB control chip, or a single-way or multi-way LED lamp control chip of other colors), a first protection resistor Ri is connected between the main controller 140 and the input end (DIN pin) of the slave control module 150, a voltage-stabilizing capacitor Cs is connected to the input end (DIN pin) of the slave control module 150, the other end of the voltage-stabilizing capacitor Cs is used for grounding, the input end (DIN pin) of the slave control module 150 is also connected to a first current-limiting resistor Rs, the other end of the first current-limiting resistor Rs is used to connect the input voltage VCC, the output end (DOUT pin) of the slave control module 120 is connected to a second protection resistor Ro, the other end of the second protection resistor Ro is used to connect the input unit 121 or other modules.
[0051] The input ends (OUTR pin, OUTG pin and OUTB pin) of the slave control module 150 are respectively connected to lamp modules, and the first lamp unit among the multiple lamp units included in the lamp module that is connected to the input end (OUTR pin, OUTG pin or OUTB pin) of the slave control module 150 is connected to the second current limiting resistor Rr, the third current limiting resistor Rg or the fourth current limiting resistor Rb between the slave control module 150, and the last lamp unit of the multiple lamp units included in the lamp module is also connected to the input voltage VCC.
[0052] The power supply voltage of the slave control module 150 can be obtained according to the following formula:
[0053] VDD=VCC-Ivdd*Rs
[0054] Wherein, VDD is the power supply voltage of the slave control module 150, VCC is the voltage input voltage, Ivdd is the static current of the slave control module 150, and Rs is the first current limiting resistor.
[0055] It is worth noting that the larger the resistance of the first current limiting resistor Rs, the lower the system power consumption, but the system anti-interference ability is weaker; the smaller the resistance of the first current limiting resistor Rs, the greater the system power consumption and the higher the operating temperature. When designing, the first current limiting resistor Rs must be selected according to the system application environment. However, the resistance value of the first current limiting resistor Rs must ensure that VDD>4V.
[0056] The resistance value of the second current limiting resistor Rr, the third current limiting resistor Rg or the fourth current limiting resistor Rb can be obtained according to the following formula:
[0057]
[0058] Wherein, Rrgb is the resistance value of the second current limiting resistor Rr, the third current limiting resistor Rg or the fourth current limiting resistor Rb, N is the number of lamp units connected in series, Vled is the voltage drop of the lamp unit, Vds is the port voltage, and Iled is the port output current.
[0059] In one embodiment, the value of the voltage stabilizing capacitor Cs may be 0.1 uF, the value of the first protection resistor Ri may be 1 KΩ, and the value of the second protection resistor Ro may be 180Ω.
[0060] It is understandable that the user can flexibly set the value of each component according to the functional requirements of the lighting device, and the present application does not limit the specific value of each component.

[0062] The mobile terminal 210 is used to generate a control instruction and send the control instruction to the control device 100;

[0064] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the control device 100 can refer to the corresponding process in the aforementioned method embodiment, and will not be repeated here.
[0065] A control device and a control system provided by an embodiment of the present application include: a microcontrol module, a channel control module and a plurality of control modules, wherein: the microcontrol module is connected to the channel control module, and the plurality of control modules are respectively connected to the channel control module; the microcontrol module is used to determine a target transmission channel; the microcontrol module is also used to generate a target channel conduction signal according to the target transmission channel, and send the target channel conduction signal to the channel control module; the channel control module is used to determine a target control module among a plurality of control modules according to the target channel conduction signal, and connect the transmission channel between the channel control module and the target control module, so as to transmit a control signal that meets the timing requirements of the target control module through the target control module, and the control signal is a signal that controls the working state of any control module among the plurality of control modules. Thus, through the mutual cooperation between the microcontrol module and the channel control module, the channel between the target control module and the channel control module that meets the timing of the control signal is connected, so as to realize the flexible determination of the control module according to the actual needs, so as to ensure the normal transmission of the control signal and the normal operation of the control module.
