Embodiment Construction

[0025] The overall structure of the distributed electronic control system of the color sorter proposed by the present invention is shown in Figure 1, including a touch screen T1 for parameter setting, a master control machine M1 for controlling public peripherals and transmitting touch screen commands, and a plurality of users For heterochromatic rice identification, high-speed jet valve detection control units S1, S2, S3...Sn, hereinafter referred to as Sx, x=1, 2...n. Each detection and control unit Sx realizes 12-channel signal detection and injection valve control, but each detection and control unit is completely independent, so that the detection and control functions of hundreds of channels can be distributed to multiple detection and control units Sx , which simplifies the circuit design and software design of each detection control unit. The main control machine M1 is connected to multiple detection and control units Sx through the CAN bus, and the detection and contr...

Abstract

A distributed electronic control system of rice color selector is prepared for using touch screen to set parameters, applying master controller to control common-external device and to transmit commands of touch screen, applying multiple detection control unit to identify out rice in unusual color and to control air injection valve, using each said detection control unit to control 12 channels of signal detection and air injection valve control, connecting master controller to multiple detection control unit through CAN bus for making convenience in increasing or decreasing channel numbers of color selector.

Description

technical field [0001] The invention belongs to the technical field of electronic control, and in particular relates to a distributed electronic control system for a rice color sorter. Background technique [0002] With the improvement of living standards, people need to eat high-quality rice. Pure mechanical processing can only remove impurities such as bran powder and bran in rice, but cannot remove heterochromatic rice. According to the light transmittance of different colors of rice, people have designed a rice color sorter based on optical sensors to remove the heterochromatic rice in the rice. The original rice color sorter adopted electronic technologies from the 1980s to the 1990s, such as centralized control and programmable logic chips. Its disadvantages are: (1) the design is complex, the function is simple, and it is not easy to update the software; (2) the output signal of the optical sensor needs to be connected to the controller with a long wire, and the lon...
