Intelligent control board for electronic dobby device

Abstract

The utility model relates to an intelligent control board for an electronic dobby device, which belongs to a control circuit and is used for various shuttleless looms in the textile field. Including switching power supply circuit, monitoring circuit, sensor signal input isolation circuit, RS-232 level conversion circuit, single-chip microcomputer and its peripheral circuit, multi-arm electromagnet drive circuit, weft selection electromagnet drive circuit and external signal input circuit, features: in A logic conversion circuit is connected between the sensor signal input isolation circuit and the single-chip microcomputer and its peripheral circuits; a storage circuit is connected between the monitoring circuit and the single-chip microcomputer and its peripheral circuits; the single-chip computer and its peripheral circuits are connected with a loom chain output circuit. Advantages: The logic conversion circuit can generate interrupts in real time according to the changes of sensor signals, and obtain corresponding strobe signals through logical combination, making the control more accurate; the storage circuit can reliably store a large amount of data, and under the protection of the backup battery, even The data will not be lost even when the power is off; the interlocking output circuit of the loom can transmit data reliably, and the misoperation of the loom is effectively prevented through the interlock mechanism.

Description

Technical field [0001] The invention relates to an intelligent control board for an electronic dobby device, belonging to a control circuit, and used for various shuttleless looms in the textile field. Background technique [0002] Various shuttleless looms in textile machinery mostly use dobby devices (referred to as "dobby") to realize the heddle lifting action and shedding movement required by the weaving process, that is: the organization signal designed according to the fabric pattern, and the dobby device Recognize and transform into the heald lifting action, after being lost to the heald frame of the loom, the heald frame drives the warp yarn to form up and down opening movements, thereby weaving various fabrics that meet the requirements of the pattern. The traditional mechanical dobby device with pattern paper (or called pattern board) as the signal input form of the organization, due to difficult pattern replacement, complicated pattern paper management, low weaving eff...

Problems solved by technology

However, the original control boards for electronic dobby generally only consider the use requirements of the electronic dobby itself, and simply realize the basic functions of storing and sending organizational data, the control function is not perfect, and due to the imperfect circuit design, making The control board lacks anti-interference ability in harsh situations, and data loss, transmission failure and even malfunction often occur during use, which affects the use effect of the electronic dobby and the performance of the shuttleless loom.
