Technical field
The present invention relates to a kind of weight sorting machines, more particularly, to a kind of weight sorting system for alleviating host pressure and side
Method.
Background technique
Weight sorting machine is the mechanical equipment that sizing screening is carried out to product weight, can be by the product of different weight range
Different firing lines is screened, manually-operated financial resources and time are saved.The mechanism of current weight sorting machine, using list
One master controller carries out logic control, and by host centralized control, the complexity for causing wiring to work increases a large amount of I/O port
Adding, while a large amount of power supply power consumption concentrates on host machine part, this is very fatal for the reliability of power-supply system, while by
Largely controlling I/O port in host makes the task amount of host very huge, this requires the performance requirement of MCU is higher and higher, pole
Big increases system design difficulty and cost.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of alleviation host pressure
Weight sorting system and method.

MCU obtains weight data, and generates logical action data and be sent to FPGA.
After the FPGA receives the logical action data that adjacent FPGA is sent, ID matching is carried out, is tied according to matching
It is decisive and resolute to determine logical action data being sent to MCU or next stage slave station.
Compared with prior art, the invention has the following advantages that
(1) use distributed structure/architecture, main control unit and multiple slave stations use series system successively to communicate, mechanical action be by
A large amount of concurrent logical action task can be split (each slave station is responsible for) in this way, the calculating to host by slave control
Capability Requirement substantially reduces.
(2) a large amount of I/O ports are dispersed, and reduce wiring complexity and the design wiring of host computer side.
(3) cable greatly reduces, and can greatly optimize product reliability.
(4) power has obtained dispersing significantly, facilitates heat dissipation design and EMC protection design and safety design.
(5) Ethernet interface enhances the extended capability of system.
