Embodiment Construction
[0014] The cotton foreign fiber sorting machine control system of the present invention adopts the design based on the embedded microcontroller MPC8245, expands the PCI bus, designs or purchases image acquisition cards, gigabit network cards, graphics cards and serial port cards respectively, realizes different functions, and coordinates Cooperate, and finally complete the foreign fiber removal work. Such as figure 1 As shown, the cotton foreign fiber sorting machine control system adopts the following design method.
[0015] It includes the main controller MPC8245 for controlling the drive device to remove foreign fibers. The controller MPC8245 expands the 8MB FLASH chip to store the embedded operating system, file system and application program; the controller MPC8245 expands the SDRAM chip to use to run embedded operating systems, file systems, and applications.
[0016] Expand the PCI bus, and set the PCI slot connected to the PCI bus of the main controller MPC8245.

A cotton foreign fiber sorting machine control system comprises a main controller MCP8245 used for controlling a driving device to carry out foreign fiber eliminating, a PCI slot connected with a PCI bus of the main controller MPC8245, a linear array camera used for collecting image data, an image capture card used for executing a foreign fiber recognition algorithm and based on the PCI bus, a display system used for displaying the image data and based on the PCI bus, and a serial port card used for being communicated with the foreign fiber eliminating driving device and based on the PCI bus. The cotton foreign fiber sorting machine control system and a control method which are based on the microcontroller MPC 8245 are used for resolving the problems that an existing system adopting an industrial control computer difficultly guarantees real-time performance, and a system adopting multiple microcontrollers is too complex.
Description
technical field [0001] The invention relates to the control of a cotton foreign fiber sorting machine, in particular to a cotton foreign fiber sorting machine control system based on a microcontroller MPC8245. Background technique [0002] During the cotton collection process, a large amount of foreign fibers are mixed into the raw cotton. Foreign fibers (referred to as foreign fibers) will affect the quality of the cloth surface and the effect of dyeing, so how to remove foreign fibers has become one of the important processes in the cotton textile industry. [0003] Most of the existing foreign fiber removal equipment uses an industrial computer as the main controller, expands the image acquisition card through the PCI (Peripheral Component Interconnect) bus, executes the image processing program, determines the position of the foreign fiber, drives the removal device, and completes the removal of the foreign fiber. In the foreign fiber removal machine, the time interval ...
