Problems solved by technology

[0004] At present, there are relatively few studies on networked speed control platforms for brushed DC motors, and most of them communicate through wired networks. The platform has poor flexibility and is easily affected by regions.
Moreover, the existing platforms are generally control systems designed based on single-chip microcomputers, DSPs, and STM32 processors, and only use a single bare-metal program for control
Therefore, for the kernel that is separated from the operating system, on the one hand, there is no powerful arithmetic unit to support complex algorithms or internal operations of the program; lack of thoughtfulness

Abstract

The invention discloses a brush direct current motor network speed regulating platform based on a WiFi (wirelss fidelity) wireless local area network. The brush direct current motor network speed regulating platform comprises a remote PC (personal computer), a development board ARM11, a motor driving module L298, a rotary encoder E6B2-CWZ6C, a counting circuit module, ten brush direct current motors (expandable) and a power source module, wherein the remote PC is used for sending various motor rotation speed signals to the development board ARM11 through the WiFi wireless local area network; a microcomputer ARM11 is used for converting each rotation speed signal into corresponding multi-path PWM (pulse width modulation) waves, and outputting to the motor driving module L298N; an output path module of the motor driving module L298N is used for realizing the signal phase verification, frequency doubling and counting, and then sending into a port GPIO of the development board ARM11; a port GPN of the GPIO is used as an external interruption receiving port, and the microcomputer ARM11 is used for collecting the counting pulse of the counting circuit module, so as to realize the signal phase verification, frequency doubling and counting, and then send into the port GPIO. The brush direct current motor network speed regulating platform has the advantages that by combining the WiFi and the microprocessor, the region limitation is broken; the bottom interface of the development board is fully utilized, and the speed regulating and detection of a wireless network of a plurality of brush direct current motors are realized.

Description

technical field [0001] The present invention relates to the field of brushed DC motor networked speed regulation platform based on WiFi wireless local area network, in particular to a design of the latest brushed DC motor networked speed regulation platform based on ARMv6 architecture and ARM11 microprocessor supporting wireless communication . Background technique [0002] With the development and cross-infiltration of communication technology, computer network and control science, the system structure becomes more and more complex, the spatial distribution becomes wider and wider, and the requirements for control performance are also higher and higher. This brings new opportunities and challenges to the development of automation technology. The biggest difference between the networked control system and the traditional control system is that its communication method is based on the network, rather than the traditional point-to-point communication method, which reflects th...
