Further, referring to fig. 2, the power supply module 11 includes a rectifier bridge, a first resistor R1, a first diode D1, a zener diode DZ1, a first capacitor C1, a second capacitor C2, and a voltage regulator L DO, an input end of the rectifier bridge is connected to an ac input end, an output end of the rectifier bridge is connected to one end of the first resistor R1, the line voltage detection module 12, and the controlled device 10, another end of the first resistor R1 is connected to an anode of the first diode D1 and a cathode of the zener diode DZ1, a cathode of the first diode D1 is connected to one end of the first capacitor C1 and an input end of the voltage regulator L DO, an output end of the voltage regulator L DO is connected to one end of the second capacitor C2, the control module 13, and the wireless module 14, and an anode of the zener diode DZ1, another end of the first capacitor C1, a GND terminal of the first capacitor C L, and another end of the second capacitor C2 are all grounded.

In specific implementation, after the high-voltage alternating current is rectified by the rectifier bridge, one path of the alternating current outputs a line voltage to the line voltage detection module 12 and the controlled device 10, so as to provide a detection source for the subsequent control module 13 to obtain a detection signal with the same period as the line voltage, and synchronously supply power to the controlled device 10, and the other path of the alternating current converts the high-voltage alternating current into 18V direct current through the first resistor R1 and the voltage stabilizing diode DZ1, then charges the first capacitor C1 after being isolated by the first diode D1, and outputs the 18V direct current after being reduced into stable 3.3V direct current through the voltage stabilizer L DO to the control module 13 and the wireless module 14 so as to provide stable power supply voltage for the control module 13 and the wireless module 14, so.

Preferably, referring to fig. 3, the control module 13 includes a counter 131, an instruction receiving unit 132 and an output conversion unit 133, the counter 131 and the instruction receiving unit 132 are both connected to the output conversion unit 133, the counter 131 is further connected to the line voltage detection module 12, the instruction receiving unit 132 is further connected to the wireless module 14, and the output conversion unit 133 is further connected to the controlled device 10. In this embodiment, the counter 131, the instruction receiving unit 132, and the output converting unit 133 may be integrated in the microcontroller U1, but other implementation manners such as a separate arrangement may also be adopted in other embodiments, and the present invention is not limited thereto. The counter 131 is configured to add 1 when a rising edge interrupt or a falling edge interrupt of the detection signal is detected every time, and clear to restart counting when a count value is a second set value; the instruction receiving unit 132 is configured to receive and store the status data when detecting an output interruption of the wireless module 14; the output conversion unit 133 is configured to read currently stored state data when the detection signal outputs a rising edge interrupt or a falling edge interrupt and the count value is a first set value, and output a corresponding dimming signal to the controlled device 10 according to the current count value and the state data.

Specifically, the counter 131 counts the period of the detection signal output by the line voltage detection module 12, in a specific implementation, the analog comparator in the microcontroller U1 is used to compare the detection signal output by the line voltage detection module 12 with a reference voltage, or an IO rollover threshold is directly used to obtain a square wave signal with a period equal to the period of the detection signal in the microcontroller U1, the period is denoted as Tvc, the counter 131 is cleared after the power-on initialization is completed, 1 is added when the rising edge or the falling edge of the detection signal is interrupted every time, and counting is restarted after the count value is a second set value is cleared, because the power-on initialization time difference of the same microcontroller U1 in each device is very small, when multiple devices are powered on simultaneously, the influence on the synchronous control can be almost ignored. And the control module 13 further receives and stores the state data when the instruction receiving unit 132 detects that the output of the wireless module 14 is interrupted, that is, when the state synchronization control of a plurality of devices is performed, the wireless module 14 of each device receives and transmits the state data input from the outside to the instruction receiving unit 132, the instruction receiving unit 132 receives and stores the state data when the wireless module 14 detects that the rising edge interruption or the falling edge interruption is output by the wireless module 14 for subsequent call, and when the device state is adjusted, the output conversion unit 133 reads the currently stored state data when the rising edge interruption or the falling edge interruption is output by the detection signal and the count value is the first setting value, and outputs the corresponding dimming signal to the controlled device 10 according to the current count value and the state data.

That is, the output conversion unit 133 outputs the rising edge interrupt or the falling edge interrupt as the synchronous signal by the detection signal, and uses the count value as the state change period, specifically, reads the currently stored latest state data when the first setting value is used, clears the first setting value to restart the counting when the second setting value is used, if no new state data is received before the first setting value is counted again, the obtained state data is not changed, the dimming signal is also not changed, the controlled device 10 continues to work according to the current state, if new state data is received before the first setting value is counted again, the obtained state data is the updated state data, and outputs a corresponding new dimming signal to the controlled device 10 according to the new state data, because the line voltage detection module 12 of each device is synchronized after the devices are powered on, the count value of the counter 131 is equal when the line voltage detection module 12 outputs the interrupt, therefore, when the output conversion unit 133 outputs the dimming signal to the controlled device 10, the state of the controlled device 10 is also updated synchronously, so that the state synchronous control of the plurality of devices without time difference is realized.

The control module 13 further includes a data register and a status memory, and the instruction receiving unit 132 is specifically configured to receive the status data and shift the status data to the data register when detecting that the output of the wireless module 14 is interrupted, determine whether a preamble of the current status data is equal to a preset value, and store the status data in the status memory if the preamble is equal to the preset value, that is, when receiving the status data, receive the current status data after detecting that the output of the wireless module 14 is interrupted, but not store the current status data in the status memory, but shift the current status data to the data register, determine whether the preamble is equal to the preset value, that is, determine whether the current status data is valid data, store the status data in the status memory if the current status data is valid, otherwise discard the current status data to ensure that each time the received status data is valid data, avoid a subsequent device status control error due to a status data error, and ensure the stability and reliability of the device operation.

Further, the output conversion unit 133 is specifically configured to map the dimming state corresponding to the current count value in the read state data to a dimming signal, and output the dimming signal to the controlled device 10, where the dimming signal may be a PWM dimming signal or an analog voltage signal, and for example, the controlled device 10 is an RGB three-color lamp, and may adjust brightness or color by receiving three dimming signals of R-OUT, G-OUT, and B-OUT output by the output conversion unit 133, a duty ratio or a dimming voltage of the dimming signal is linear to brightness of the L ED lamp, when the duty ratio is 100% or the dimming voltage is 3.3V, the L ED brightness is maximum, and when the duty ratio is 0% or the dimming voltage is 0V, the corresponding L ED lamp is turned off.

For example, the first setting value of the preset counter 131 is 0, the second setting value is 299, and if the dimming state corresponding to the currently received state data 1 is Red on 50 Tvc cycles and off 50 Tvc cycles; green lights 50 Tvc cycles, lights 50 Tvc cycles; the Blue lights 50 Tvc cycles and goes OUT 50 Tvc cycles, and periodically flashes according to the rule, the output conversion unit 133 outputs a corresponding dimming state according to the current count value and the dimming state, specifically, when the line voltage detection module 12 interrupts the output and the count value is equal to 0-49, the R-OUT outputs 3.3V, G-OUT and the B-OUT outputs 0V, and when the count value is equal to 50-99, the R-OUT, the G-OUT and the B-OUT outputs 0V; when the line voltage detection module 12 outputs interrupt and the count value is equal to 100-149, the G-OUT outputs 3.3V, R-OUT and the B-OUT outputs 0V, and when the count value is equal to 150-199, the R-OUT, the G-OUT and the B-OUT outputs 0V; when the line voltage detection module 12 outputs interrupt and the count value is equal to 200-249, B-OUT outputs 3.3V, R-OUT and G-OUT outputs 0V, and R-OUT, G-OUT and B-OUT outputs 0V when the count value is equal to 250-299; because the counter 131 counts continuously from 0 to 299 periodically, the line voltage detection module 12 outputs an interrupt as a synchronous signal, the counter 131 counts as a state change period, and the PWM dimming signal or the analog voltage signal is periodically output to the controlled device 10, and each count value is added by 1 to represent a Tvc period, so that the working state of each device can be adjusted by the count value and the dimming state in the state data in combination with outputting a corresponding dimming signal, and synchronous control of a plurality of devices is realized.

In order to better understand the synchronous control process of the device state synchronous control device provided by the present invention, the following describes the working process of the device state synchronous control device provided by the present invention by taking an application embodiment with reference to fig. 4:

similarly, taking the controlled device 10 as an RGB three-color lamp as an example, the first setting value of the preset counter 131 is 0, the second setting value is 299, and the dimming state corresponding to the state data 1 is that Red is on for 50 Tvc cycles, and Red is off for 50 Tvc cycles; green lights 50 Tvc cycles, lights 50 Tvc cycles; blue lights 50 Tvc cycles, goes out 50 Tvc cycles, and periodically flickers according to the rule, and state data 2 corresponds to the state: red Red lights 20 Tvc cycles, goes out 80 Tvc cycles; green lights 20 Tvc cycles and goes out 80 Tvc cycles; blue lights 20 Tvc cycles and goes out 80 Tvc cycles; periodically flashing according to the rule.

When the two RGB three-color lamps are controlled to work synchronously, after power-on, the two L ED lamps L EDA and L EDB are initialized and reset the corresponding counters 131CNTA and CNTB respectively, the output period Tvc of the 300 line voltage detection modules 12 is counted periodically, when the output interruption of the line voltage output modules is detected and the counters 131CNT are the first set value 0, the L EDA and L EDB read out state data from the state memories respectively and flicker according to the state set by the state data, and when the output interruption of the line voltage output modules is detected and the counters 131CNT are the second set value 299, the corresponding counters 131A and CNTB are reset respectively.

For example, in the first counting period, when CNT is 0, status data 1 is read from the status memory, and the status of L EDA and L EDB is changed correspondingly according to the status set by status data 1 according to the count value of counter 131, that is, the red, green and blue lamps are alternately turned on for 50 Tvc cycles in sequence and then turned off for 50 Tvc cycles, in the second counting period, L EDA and L EDB continue to change according to the status set by status data 1, at a certain moment, due to the wireless transmission rate or distance difference, L EDA and L EDB detect the interruption of the output of wireless module 14 in sequence, receive new status data 2 and store it in the respective status memories, in the third counting period, when CNT is 0, status data 2 is read from the status memory, and the status of L EDB and L EDB is changed correspondingly according to the status set by status data 2 of counter 131, that the red, green and blue lamps are alternately turned on for 80 Tvc cycles and then turned off for 20 Tvc cycles, thereby realizing that two devices are synchronously controlled in the third cycle, and providing more effective synchronization control over the synchronization of the wireless module, and further avoiding the problem of the synchronization of the control of the device, and the synchronization of the invention, and the synchronization control of the synchronization of the wireless modules, which the synchronization control of the wireless module, and the synchronization of the synchronization control device, and the synchronization of the synchronization control device, which the synchronization control device, and.
