Embodiment Construction

[0046] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. Such as figure 1 As shown, the system (this system) of the present invention that uses an intelligent terminal to control pulse width modulation output is composed of an intelligent control module, a wireless gateway module, and 1 to 255 PWM control slave modules connected. The intelligent control module sends control commands, which are analyzed by the wireless gateway module and sent to different PWM control slave modules, and each PWM control slave module responds to the control commands, outputs the corresponding PWM modulation signal, and controls the output power of the power supply to the electrical equipment . Each PWM control slave module returns the address of the current PWM control slave module and the device type information of the controlled device to generate response information 1 to the wireless gateway module, and the wireless...

The radio network gateway controller and the PWM sub machine controller are connected through a wireless sensor network. Compared with the prior art, a structure of the intelligent control module, the radio network gateway module, the PWM sub machine controlling module is adopted, the smart phone is operated to control the PWM sub machine controller to output a PWM analog signal, voltage of an adjustable voltage device and output power of the adjustable voltage device are controlled, and a plurality of devices with electricity and power adjustable can be operated and controlled conveniently.

Description

technical field [0001] The invention relates to a control system and device for switching and output power regulation, in particular to a remote control system for controlling pulse width modulation output by using an intelligent terminal through a wireless sensor network. Background technique [0002] Pulse Width Modulation (PWM) is a very effective way to control analog circuits by using the digital output of a microprocessor. It is widely used in the field of power control, such as light-emitting diode LED light brightness adjustment, motor switching and speed adjustment. However, the traditional PWM modulation is mainly used for short-distance real-time control, and it is incapable of controlling a large number of control objects that need to be controlled remotely, such as adjusting the brightness and switching operations of 100 LED lights. Control, data information cannot be collected, stored and analyzed in a centralized manner. Contents of the invention [0003] T...
