Description
Technical field
The present invention relates to a kind of communication transfer agreements more particularly to a kind of high performance needle selection device knitting machine parallel data to pass
Defeated agreement.
Background technique
What needle selection device knitting machine communication interface agreement was usually used at present is the driving of 8 position datawire clocking informations；Needle selection
Device communication interface agreement is mainly made of 8 position datawires and a bit clock signal output signal.Transmission mode is in clock
Data in rising edge latch data bus, a little Data Labels are address signal, and in the failing edge of clock signal that data are total
Data on line are latched as data information, and the data of multichannel can be transferred out by ceaselessly repeating this process；It specifically drives
Dynamic timing diagram, as shown in Figure 1；But have the disadvantage in that (1) transmitted data amount is few, 1 byte data is transmitted each time.(2)
Transmission error tolerance ability is poor.Because one data word section can only be transmitted, the reliability for not making to verify data not can guarantee.
Summary of the invention
The purpose of the present invention is to provide a kind of high performance needle selection device knitting machine parallel data transmission agreements, on solving
State the problem of proposing in background technique.
The purpose of the present invention is be achieved by following technical proposals: a kind of high performance needle selection device knitting machine and line number
According to transport protocol, knitting machine sends data to be carried out data transmission by slide cam selector communication interface agreement to slide cam selector, the needle
Loom slide cam selector communication interface agreement is made of double a clock signal driving datas and 8 position datawires comprising the steps of:
Step 1, knitting machine are to slide cam selector output signal data；
When step 2, the signal data pass through needle selection device knitting machine communication interface, under double a clock signal drivings, when
The rising edge of clock signal 1 (CLK1) exports slide cam selector address number (address 1), and clock signal 2 (CLK2) is low level, auxiliary at this time
The correctness of clock signal 1 (CLK1) check information；
The rising edge of clock signal 2 (CLK2) in step 3, step 2 sends out the first data L, at this time clock signal 1
It (CLK1) is high level, the correctness of auxiliary clock signal 2 (CLK2) check information；
The failing edge of clock signal 1 (CLK1) in step 4, step 3 exports first data H, at this time clock signal 2
It (CLK2) is high level, the correctness of auxiliary clock signal 1 (CLK1) check information；
The failing edge output output verification result and crc value of clock signal 2 (CLK2) in step 5, step 4, this is constantly
Clock signal 1 (CLK1) is low level, the correctness of auxiliary clock signal 2 (CLK2) checking signal.
Step 6, slide cam selector receive the slide cam selector address number (address 1), data H and data L, are obtained by operation
New crc value out.
Step 7 compares new crc value that step 6 is calculated and the crc value that step 5 output obtains, if not
Match, then this packet data is invalid, and data are correct if matching.
The new crc value is calculated by slide cam selector address number (address 1)+data H+ data L.
Compared with prior art, which has following
Beneficial effect；
(1) 2 byte datas can be transmitted in the same transmission cycle, it can be very convenient for slide cam selectors more than 8 knives
The complete all data of once transmission.
(2) CLK1 is used, CLK2 doubleclocking mutually verifies, and ensure that the integrality of signal.
(3) CRC check is had in the data of transmission and terminal guarantees received data and transmission by comparing crc value
Data are completely the same.
