Loom initialize session of the present invention, slow train are weaved session, are normally weaved session and error handling processing and recover all to realize in the software interface mode of standard.
The present invention compared with prior art has the following advantages and effect:
● electronic jacquard communication protocol control device is simple in structure, antijamming capability is strong, this is because used highly integrated technical grade embedded chip, and adopt serial transmission line to be connected between electronic jacquard communication protocol control device and the electronic jacquard loom controller, easy to connect, simple;
● simplified the exploitation of electronic jacquard loom controller widely, electronic jacquard loom controller is as long as the data that loom is needed send electronic jacquard communication protocol control device to, and electronic jacquard communication protocol control device will be by oneself and the communication of loom; Simultaneously, electronic jacquard communication protocol control device can extract the loom data that electronic jacquard machine needs automatically, sends to electronic jacquard loom controller.
● a little less than the coupling between electronic jacquard communication protocol control device and the electronic jacquard loom controller, that is to say that electronic jacquard communication protocol control device is an independently module, can add at random as required or unload, and can not influence the function of electronic jacquard loom controller.
● electronic jacquard loom controller has adopted the software interface of standard to calling of electronic jacquard communication protocol control device, the application that is about to various sessions is encapsulated in a series of specific functions, thereby makes electronic jacquard communication protocol control device have good versatility; The jacquard control system of other types as long as call these functions by standard, also can use electronic jacquard communication protocol control device and loom to carry out communication when exploitation.
● because communication controller CPU adopts 32 high-speed chips, according to the test result of the test platform of simulation, in theory electronic jacquard communication protocol control device can reach 750 shuttles/minute weaving speed; Actual conditions see, electronic jacquard communication protocol control device can satisfy at least 450 shuttles/minute weaving speed;
● owing to the good realization to communications protocol, electronic jacquard communication protocol control device can interconnect with the loom that comprises use communications protocol such as Vamatex, Picanol and Somet.
