Electronic jacquard communication protocol control device

Abstract

The present invention relates to a loom electronic jacquard machine communication protocol controller and its realization method. The loom electronic jacquard machine communication protocol controller includes a communication controller CPU, an input part and an output part, and the communication controller CPU and the input part and the output part The parts are connected separately, and the built-in program of the communication controller CPU is responsible for receiving and processing control information and realizing the control requirements of the electronic jacquard machine controller to the loom according to the requirements of the communication protocol; the input part is connected with the serial port of the electronic jacquard machine controller; The output part is connected with the communication port of the loom, and the implementation method includes the loom initialization session, the slow weaving session, the normal weaving session, and error handling and recovery. Compared with the prior art, the present invention has the advantages of fast processing speed, strong anti-interference ability, simple structure, good independence and universality, easy development and maintenance, and high reliability.

Description

Technical field: [0001] The invention relates to a communication protocol controller for an electronic jacquard loom, which is mainly used in the textile industry and is also suitable for communication between other devices based on the VDI communication protocol. Background technique: [0002] At present, most of the data exchange between the electronic jacquard machine and the loom is connected by means of electrical signals. The biggest advantage of this connection method is that it is simple, but the disadvantage is that it is not suitable for more complex data interaction occasions. Complex data interaction must be in the form of a communication protocol. The reason is that after the control signal increases to a certain amount, it is impossible to solve the problem by increasing the transmission line, because this will lead to the complexity and cost of the connected device. Therefore, it is difficult to control Encoding must be adopted. In order to ensure the reliabil...

Problems solved by technology

In fact, before the implementation of the present invention, the loom based on the communication protocol has not adopted the domestic electronic jacquard machine to match it, and the reason is that the control technology based on the communication protocol has not been mastered.
