Abstract

The invention discloses a self-adaptive PWM controller, which comprises a microprocessor module, a temperature sensor module, a temperature sensor module and a PWM control module, wherein the RS485 communication module is in bidirectional connection with the microprocessor module and is used for being connected with an external host and receiving a control command of the external host; the USART communication module is in bidirectional connection with the microprocessor module and is used for being connected with peripheral equipment and receiving a control command of the peripheral equipment;the external analog quantity input control module is in bidirectional connection with the microprocessor module and is used for receiving data transmitted by peripheral equipment; the PWM output androtating speed acquisition module is in bidirectional connection with the microprocessor and is used for outputting a PWM control signal; the over-current protection module is in bidirectional connection with the microprocessor module and is used for realizing over-current protection; and the IO module is in bidirectional connection with the microprocessor module and is used for receiving and transmitting data. The self-adaptive PWM controller has the advantages of multiple functions, high measurement precision, convenience in use and the like.

Description

technical field [0001] The invention relates to the technical field of electronic controllers, in particular to an adaptive PWM controller. Background technique [0002] In industrial production, many devices need to control their working status through PWM, such as motors, cooling fans, motors, steering gears, etc. A PWM controller is a smart regulator with a microprocessor. Most of the PWM controllers currently on the market are not programmable or have single functions, low output power, and poor scalability, which cannot meet certain industrial needs. Contents of the invention [0003] The technical problem to be solved by the present invention is how to provide a self-adaptive PWM controller with various functions, high measurement precision and convenient use. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an adaptive PWM controller, comprising: a microprocessor module, a temperature se...
