Problems solved by technology

Such a system is too large and the distance is too long to be guaranteed to work reliably
Therefore, large jacquard machines are prone to skip stitches and missing stitches.
[0004] With the increase of the speed of the shuttleless loom, the speed of the electronic jacquard machine is also required to reach 600RPM. The increase of the speed means that the time for updating data is shortened, and the high data rate is not good for the anti-interference ability of the system.
For data lines, the higher the transmission rate, the

Abstract

The invention relates to a control system of electronic jacquard machine including a plurality of electromagnetic needle selector, which at least divided to two separate electromagnetic needle selector sets, and each electromagnetic needle selector set is supplied by separate power supply; a main controller, which contains a embedding type microprocessor, a storage mechanism for storing pattern data, Wherein, data input end of the embedding type microprocessor is connected with each electromagnetic needle selector set. Before spinning, the main controller reads spinning pattern data in the storage mechanism and carries format conversion, storage and grouping of data, when the jacquard machine working, the embedding type microprocessor outputs each group of spinning pattern data to the corresponding electromagnetic needle selector set for carrying pattern operation. Due to directly driving the electromagnetic needle selector set by the main controller, the electromagnetic needle selector can work reliably, contradiction of high data transportation speed and cable length is solved, and due to avoiding using longer cable to transport data, immunity of the control system is greatly increased.

Description

technical field [0001] The invention belongs to the field of textile machinery, in particular to a control system for an electronic jacquard machine with a large number of stitches. Background technique [0002] Most of the current electronic jacquard machines have a similar electromagnetic needle selector structure. A serial input and parallel output register is installed on the electromagnetic needle selector. The output end of the register is connected to a triode for driving. between coils. The high level or low level of the output terminal of the register can control the conduction or cut-off of the triode. When the triode is turned on, the coil is energized, and the electromagnetic needle selector operates. When the triode is cut off, the coil is not powered, and the electromagnetic needle selector is not. corresponding action. Therefore, the external controller can control the action of the electromagnetic needle selector by writing different...
