As shown in fig. 2, the synchronization signal transmitter generates a continuous pulse signal through the first pulse signal generator, and the continuous pulse signal can be used as a synchronization signal to perform synchronous control on each intelligent power supply circuit. In an embodiment of the present invention, in order to enhance the stability of the first continuous pulse signal, the first pulse signal generator may be implemented by using a Direct Digital Synthesizer (DDS). In practical application, the existing AD9951 direct digital signal synthesizer can be adopted to realize the generation of the continuous pulse signal. In other embodiments, the circuit may be constructed using discrete components such as an operational amplifier to generate a continuous pulse signal. The continuous pulse signal is a common signal and can be generated in various ways. For the sake of brevity, specific circuitry thereof is not described in detail herein. The first wireless communication module may be a frequency modulation module, so as to implement modulation and then transmission of the first continuous pulse signal, thereby reducing delay. Since wireless communication modules with complex communication protocols (e.g., WIFI modules) typically incur delays due to the complex packing and unpacking processes of the protocols, the cost of communication modules with complex protocols is relatively high. Communication modules with complex protocols may also be used in other situations where the synchronization requirements are not precise.

As shown in fig. 1 and fig. 2, each of the intelligent power circuits may simultaneously receive the first continuous pulse signal, which is transmitted wirelessly by the synchronization signal transmitter and has been modulated, within a certain range, and may respectively demodulate the received wireless signals through the second wireless communication modules in the intelligent power circuits. Therefore, the second wireless communication module on each intelligent power supply circuit can synchronously demodulate and output the first continuous pulse signal and respectively output the first continuous pulse signal to each controller through the signal output end. Therefore, the controllers on the intelligent power supply circuits can respectively acquire the first continuous pulse signals, and synchronization of acquisition of the synchronous signals is realized.

And each motor is a direct current motor, and the rotating speed of the motor is controlled by direct current voltage. Therefore, the motors are electrified at the same time, and the electrified voltage is the same voltage value, so that the motors can synchronously rotate at the same rotating speed. Thereby realizing synchronous drive control of each motor. High-precision synchronous rotation control of a motor on the assembly line is met.

Referring to fig. 3 and 4, the controller includes: the first synchronous signal generating module is used for generating a first synchronous signal according to the first continuous pulse signal; as shown in fig. 4, the first continuous pulse signal may be a plurality of continuous pulse signals. The method comprises the steps that a plurality of continuous pulse signals are input into a first synchronous signal generation module from a signal input end, the input continuous pulse signals are detected through the first synchronous signal generation module, when the input continuous pulse signals are detected to be normal, detection is completed, a first synchronous signal is generated, and the first synchronous signal is output.

The first synchronous signal is output to the signal selection module, the first synchronous signal can be selectively output through the signal selection module, the signal is used as a synchronous signal, and a synchronous rotation switch signal is output to the voltage conversion circuit to control the power supply output of the voltage conversion circuit, so that the motor is driven to rotate synchronously.
Referring to fig. 2 and 3, the intelligent power adapter system further includes: the second pulse signal generator is connected with the controller and is used for generating a second continuous pulse signal; in some cases, the first continuous pulse signal may be acquired due to a communication failure of the second wireless communication module, and the like, so as to avoid a situation that synchronization cannot be performed due to the fact that the first continuous pulse signal cannot be acquired. And generating a second continuous pulse signal by the second pulse signal generator so as to continuously provide the continuous pulse signal under the condition that the first continuous pulse signal cannot be normally acquired.
The synchronous reset end of the second pulse signal generator is also connected with the first synchronous signal output end so as to synchronously reset the second pulse signal generator through the first synchronous signal; in order to achieve the best possible synchronization, the second pulse signal generator generates the same continuous pulse signal in the same time period as the first pulse signal generator. That is, the continuous pulse signals generated by the second pulse signal generator and the first pulse signal generator are synchronous pulse signals. In use, the second pulse signal generator may be reset synchronously by the first synchronization signal. In order to increase the stability of the second continuous pulse signal, the second pulse signal generator may be implemented by Direct Digital Synthesizer (DDS), which may be implemented by an existing AD9951 Direct Digital signal Synthesizer. In other embodiments, the circuit may be constructed using discrete components such as operational amplifiers to generate continuous pulse signals.
The controller further comprises a second synchronous signal generating module, the second synchronous signal generating module is connected with the signal selecting module, and the second synchronous signal generating module is used for generating a second synchronous signal according to the second continuous pulse signal; as shown in fig. 4, the second continuous pulse signal may be a plurality of continuous pulse signals. And a plurality of continuous pulse signals are input into the second synchronous signal generating module from a signal input end, the input continuous pulse signals are detected through the second synchronous signal generating module, when the input continuous pulse signals are detected to be normal, the detection is completed, a second synchronous signal is generated, and the second synchronous signal is output to the signal selecting module.
The signal selection module is further used for selectively outputting the second synchronous signal when the first synchronous signal is invalid so as to generate the synchronous rotation switch signal. The signal selection module judges whether the first synchronization signal and the second synchronization signal are normal or not. And when the first synchronous signal is abnormal, selecting the second synchronous signal as the synchronous signal to be output.
The controller further includes: the first synchronous signal normal module is connected with the signal selection module and used for generating a first synchronous signal normal signal according to the first continuous pulse signal and outputting the first synchronous signal normal signal to the signal selection module, and when the signal selection module detects that the first synchronous signal normal signal is in a normal state, the first synchronous signal is selected to be output, otherwise, the second synchronous signal is selected to be output.

Referring to fig. 3 and 4, in an embodiment of the present invention, the first continuous pulse signal and the second continuous pulse signal are signals greater than 3 pulses, respectively. For example, 10 consecutive pulse signals may be used. And detecting each pulse signal through the first synchronous signal generating module. When the first synchronous signal generation module detects the last pulse of the first continuous pulse signal, outputting the first synchronous signal; similarly, when the second synchronization signal generation module detects the last pulse of the second continuous pulse signal, the second synchronization signal is output. That is, when the continuous pulse signals are 10 continuous pulse signals, and the first synchronization signal generation module and the second synchronization signal generation module detect the tenth pulse signal, the synchronization signals are respectively output.
The first synchronous signal normal module outputs a first synchronous signal normal signal when detecting the non-last pulse of the first continuous pulse signal; and when the second synchronous signal normal module detects the non-last pulse of the second continuous pulse signal, outputting a second synchronous signal normal signal. As shown in fig. 4, before the generation of the synchronization signal, the synchronization signal normal signal may be generated by the first synchronization signal normal module and the second synchronization signal normal module to determine in advance whether the first continuous pulse signal and the second continuous pulse signal are normal. The first synchronous signal normal signal is used for indicating that the first continuous pulse signal is in a normal state, and if the first continuous pulse signal is in the normal state, the first synchronous signal normal signal indicates that the first synchronous signal generating module can normally generate the first synchronous signal. Similarly, the second synchronization signal normal signal is used to indicate that the second continuous pulse signal is in a normal state, and if the second continuous pulse signal is in the normal state, it indicates that the second synchronization signal generation module can normally generate the second synchronization signal. Thus, the signal selection module can select the first synchronous signal or the second synchronous signal to be output according to the signal normal state. For example, when the first synchronization signal is in an abnormal state and the second synchronization signal is in a normal state, it indicates that the first continuous pulse signal is in an abnormal state, which may be caused by a network reason or a fault of the wireless communication module. The step of judging whether the signal is normal by the signal selection module is before the generation of the synchronous signal. Thus, the channel of the synchronization signal can be switched in advance. When the second synchronous signal is generated, the second synchronous signal is selected as a synchronous rotation switch signal in time and is output, so that the synchronism with other motors is ensured.

The specific working process is as follows: the controller generates a PWM signal through the PWM signal generation module and outputs the PWM signal to the gate of the MOS transistor Q1 so as to perform PWM on the current on the primary coil of the transformer T1 through the MOS transistor Q1. The PWM pulse width modulated power signal is transformed by the transformer T1, and is output from the secondary winding of the transformer T1. The diode D2 and the capacitor C4 form a filter circuit, and can output stable direct current power supply after rectifying and filtering the PWM pulse power supply output by the transformer T1 voltage transformation output end. The resistor R3 and the resistor R4 form a voltage division circuit, and the voltage division circuit can divide the voltage of the direct current power supply output by the voltage transformation circuit and feed the divided voltage back to the voltage detection end of the controller. In this way, the controller may adjust the duty cycle of the PWM pulse width signal according to the feedback voltage value. So as to regulate and control the voltage of the output direct current power supply and ensure the voltage stability of the direct current power supply.
The switch control circuit is respectively connected with the voltage transformation circuit and the controller, and is used for carrying out switch control on the output of the voltage transformation circuit according to the synchronous rotation switch signal so as to drive the motor to synchronously rotate.

As shown in fig. 2, a rotational cycle signal of the motor is detected by the cycle position sensor LA, and the rotational speed of the motor is detected by the rotational cycle signal. During the rotation process of the motor, the rotating speed of the motor may not reach the preset requirement due to various unknown reasons, and in order to achieve better synchronization, the driving voltage of the motor can be adjusted, so that the rotating speed of the motor can be adjusted and controlled.
