Abstract

The invention provides a method for reinforcing the communication reliability of a pattern machine serial port. The method comprises the following steps: firstly, a main control device sends a communication request instruction to a slave device within limited times, the slave device returns communication response to the main control device, and the communication is terminated; second, when the slave device does not return the communication response to the main control device, and when the time of repeatedly sending the communication request instruction exceeds a preset time, a display module controlled by the main control device displays communication abnormality; third, a storage control module controlled by the main control device stores a system site, and repeatedly sends the communication request instruction within infinite times; and fourth, when the slave device returns the communication response to the main control device, the storage control module recovers the system site, the display module recovers the display and displays communication normality, and the communication is terminated. By adopting the method provided by the invention, on the condition of not increasing the magnet ring or the shielding layer of the system, the antijamming capability of the system is better than that of other communication schemes, the bidirectional communication speed is high, and the system cost is effectively reduced.

Description

A kind of method for strengthening pattern sewing machine serial communication reliability
Technical field
The present invention relates to industrial sewing machine technical field, especially a kind of method for strengthening pattern sewing machine serial communication reliability.
Background technology
Computer embroidery machine is to be widely used in various handbag, clothing, weaving, leatherware, case and bag, footwear industry, belt, and the industrial sewing machine educating the sewing patterns such as equipment is stopped in motion.
Current computer embroidery machine communication is all adopt 232 or 485 communications, but 232 communication poor anti jamming capability, 485 efficiencies of transmission are low, and there is a large amount of electromagnetic interference in the use environment of computer embroidery machine, it is easy to communication is interfered. When finding that communication is interfered, people reduce interference usually by increasing the hardware such as magnet ring, shielding line, but this can cause hardware cost to rise; If interference time is long, causing the long-time Communications failure of system, system must restart and could normally use, and this not only results in computer embroidery machine and interrupts temporarily, loss of data, and has a strong impact on the work efficiency of computer embroidery machine.
Therefore, prior art needs to be improved.
Summary of the invention
For overcoming the above-mentioned problems in the prior art, the purpose of the present invention aims to provide one can not only strengthen capacity of resisting disturbance, can carry out again the method for strengthening pattern sewing machine serial communication reliability of both-way communication with higher speed.
The present invention reaches above-mentioned purpose by techniques below means:
A kind of method for strengthening pattern sewing machine serial communication reliability, comprises the following steps:
One, main control device sends limited number of time communication request instruction to from equipment, from equipment, main control device Returning communication is responded, and communication terminates;
Two, when main control device Returning communication not being responded from equipment, and when repeating to send communication request instruction number of times beyond pre-determined number, by the display module display communication abnormality that main control device controls;
Three, the storage control module controlled by main control device preserves system for field, and unlimited repetition sends communication request instruction;
Four, when main control device Returning communication being responded from equipment, storage control module recovery system is on-the-spot, and display module recovers display, and display communication is normal, and communication terminates.
The invention have the characteristics that
1, the on-the-spot reservation function of employing storage control module, once find that communication makes mistakes, records the current work performed, and prompting makes mistakes for communication;
2, communication is adopted to report an error retransmission mechanism, after finding miscommunication, the repeating transmission of the communication data that proceeds to make mistakes;
3, adopting the in-situ FTIR spectroelectrochemitry function of storage control module, no matter communicating interrupt how long, after communication is normal, recovers the work before communication makes mistakes, continues subsequent action and perform.
The present invention does not increase magnet ring or screen layer in system, system rejection to disturbance ability is better than other communication schemes, and both-way communication speed is high, effectively reduces system cost.
Accompanying drawing explanation
Accompanying drawing 1 is the flowchart of the present invention;
Accompanying drawing 2 is the flowchart of the embodiment of the present invention.
Detailed description of the invention
Refer to Fig. 1, a kind of method for strengthening pattern sewing machine serial communication reliability of the present invention, comprise the following steps:
One, main control device sends limited number of time communication request instruction to from equipment, from equipment, main control device Returning communication is responded, and communication terminates;
Two, when main control device Returning communication not being responded from equipment, and when repeating to send communication request instruction number of times beyond pre-determined number, by the display module display communication abnormality that main control device controls;
Three, the storage control module controlled by main control device preserves system for field, and unlimited repetition sends communication request instruction;
Four, when main control device Returning communication being responded from equipment, storage control module recovery system is on-the-spot, and display module recovers display, and display communication is normal, and communication terminates.
Now provide an embodiment, the present invention made further more detailed description:
Refer to Fig. 2, a kind of method for strengthening pattern sewing machine serial communication reliability, comprise the following steps:
One, main control device sends 1 communication request instruction to from equipment, from equipment, main control device Returning communication is responded, then communication terminates;
If main control device Returning communication is not responded by two from equipment, then main control device retransmits 20 communication request instructions to from equipment, if after wherein certain communication instruction sends, from equipment, main control device Returning communication is responded, and communication terminates;
Three, when main control device is to after equipment 20 communication request instructions of transmission, when namely reaching 20 upper limits of sending times that main control device sets, yet main control device Returning communication is not responded from equipment, by the display module display communication abnormality that main control device controls;
Four, the storage control module controlled by main control device preserves system for field;
Five, main control device carries out unlimited communication request instruction transmission to from equipment;
Six until when responding from equipment to main control device Returning communication, storage control module recovery system is on-the-spot;
Seven, display module display communication is normal, and communication terminates.
The embodiment of the present invention adopts new communication modes, it is not necessary to increase hardware, it is not required that restart, and capacity of resisting disturbance is strong, and communication efficiency is high, and system cost is low.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
