[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1, in this embodiment, as Figures 1 to 7 As shown, this embodiment provides a multi-channel switch system based on wireless communication, which includes: a microprocessor U1, a wireless communication unit and at least one output control unit; wherein the wireless communication unit and each output control unit are electrically connected to the microprocessor U1 respectively, and each output control unit is connected to a corresponding load respectively; the microprocessor U1 is suitable for obtaining an input signal through the wireless communication unit so that the microprocessor U1 sends a corresponding PWM signal to the corresponding output control unit; each output control unit is suitable for controlling the state of the corresponding load respectively.

[0028] In this embodiment, this embodiment can realize multi-way switch control and control the power supply status of multiple loads through the cooperation of the microprocessor U1, the wireless communication unit and each output control unit, and can remotely control through the mobile terminal or PC terminal, and use PWM signal for control to meet the diversified control needs.

[0029] In this embodiment, the wireless communication unit is suitable for performing data interaction with a mobile terminal or a PC terminal via Bluetooth or WIFI.

[0030] Specifically, see Figure 4 , Figure 6 The wireless communication unit includes: a communication module U4, the communication module U4 integrates at least one of a Bluetooth module and a WIFI module, and then the communication module U4 exchanges data with a mobile terminal or a PC terminal,

[0031] In this embodiment, the wireless communication unit is suitable for performing data exchange with the microprocessor U1 through a serial port.

[0032] Specifically, see Figure 4 , Figure 6The communication module U4 transmits data with the microprocessor U1 through the serial port. The microprocessor U1 receives the corresponding data and performs logic judgment processing. The microprocessor U1 controls the corresponding IO port to output the set PWM signal to the corresponding output control unit to achieve the purpose of controlling the power supply of the load.

[0033] Specifically, the internal watchdog of the microprocessor U1 can be set to prevent the program from being stuck and unable to work normally due to uncontrollable factors; the microprocessor U1 is set to determine the switch state after the communication is disconnected by reading the link-status pin state or judging the current communication state (filtering is required), and can be set to maintain the current state or turn off all switches.

[0034] In this embodiment, the output control unit includes: a MOS tube; the MOS tube is connected to the microprocessor U1 and a control switch; the microprocessor U1 is suitable for outputting a PWM signal to control the state of the MOS tube, and further control the state of the load.

[0035] Specifically, see Figure 7 Two MOS tubes form MOS tube group QT1, two MOS tubes form MOS tube group QT2, two MOS tubes form MOS tube group QT3, and two MOS tubes form MOS tube group QT4. The microprocessor U1 processes the received data and outputs PWM signals to the corresponding gates in MOS tube group QT1, MOS tube group QT2, MOS tube group QT3, and MOS tube group QT4 through the corresponding IO ports, so as to achieve the purpose of controlling the power supply of chanel1 to chanel8 lines.

[0036] In this embodiment, the multi-channel switch system based on wireless communication also includes: a power supply unit; the input end of the power supply unit is connected to the power supply, and the output end of the power supply unit is connected to the microprocessor U1, the wireless communication unit, and each output control unit.

[0037] In this embodiment, the power supply unit includes: a voltage-stabilizing power supply circuit; the voltage-stabilizing power supply circuit is suitable for stepping down the input voltage and outputting it to the microprocessor U1, the wireless communication unit, and various output control units.

[0038] In this example, see Figure 3 The voltage stabilizing power supply circuit is provided with a step-down voltage stabilizing chip U2 which can output a +5V voltage.

[0039] In this embodiment, the power supply unit further includes: an anti-reverse rectification circuit; the input end of the anti-reverse rectification circuit is connected to the power supply, and the output end of the anti-reverse rectification circuit is connected to the voltage-stabilizing power supply circuit.

[0040] Specifically, see Figure 2In order to prevent the user from connecting the positive and negative poles in reverse and causing the system to not work, 4 diodes are used to form a rectifier bridge circuit, and the power is supplied through input and GND. When the input is positive and GND is negative, the current flows through diodes D13 and D15 through VO+, passes through the load to V0-, and finally returns to GND through diodes D16 and D18. In this process, V0+ serves as the positive pole of the load and V0- serves as the negative pole of the load; when the input is negative and GND is positive, the current flows through diodes D17 and D19 through VO+, passes through the load to V0-, and finally returns to the input through diodes D12 and D14. In this process, V0+ serves as the positive pole of the load and V0- serves as the negative pole of the load.

[0041] Specifically, by providing an anti-reverse rectification circuit, it is possible to provide an input terminal without distinguishing between positive and negative poles.

[0042] Specifically, Figure 3 As shown, the debugging program can be burned into the microprocessor U1 through the chip U3 to achieve matching and communication with the wireless communication unit.

[0043] To sum up, the utility model can realize multi-way switch control and control the power supply status of multiple loads through the cooperation of a microprocessor, a wireless communication unit and various output control units, and can be remotely controlled through a mobile terminal or a PC terminal. At the same time, PWM signals are used for control to meet the needs of diversified control.
