Abstract

The invention discloses solenoid valve failure node judgment methods in a kind of electronic jacquard machine needle component, 64 way solenoid valve failures of 8 × 8 matrixes are judged using the pin scanning function of CH451 chip, DIG7~DIG0 pin is exported for column scan, SEG7~SEG0 pin all has internal pull down resistor, for row scanning input, it is connected in IG7~DIG0 pin SEG7~SEG0 pin intersection using triode, solenoid valve failure signal is for providing the base voltage of triode in electronic jacquard machine needle component, for on or off triode, corresponding signal transformation is generated in IG7~DIG0 pin SEG7~SEG0 pin, for judging the position where the fault point of solenoid valve.Structure of the invention is reasonable, solenoid valve failure and can judge malfunctioning node in a kind of electronic jacquard machine needle component of on-line checking, while generating an interrupt notification controller, and stop in emergency, and the failure occurred with system is with compared with fast-response.

Description

Solenoid valve failure node judgment method in electronic jacquard machine needle component
Technical field
The present invention relates to solenoid valve failure node judgment methods in a kind of electronic jacquard machine needle component.
Background technique
With the deep application in textile industry of electronics industry, people propose newly to textile industry individualized development Requirement.The fast development of loom promotes the development of the jacquard attachment to match therewith, and high-performance jacquard is modern textile The important directions of development are of great significance for improving fabric quality;Electronic jacquard machine is a kind of different using various colors Warp thread, weft yarn be intertwined to form the electromechanical integrated product of big-pattern tissue fabric, electronic jacquard machine and loom match, Various big-pattern jacquard fabrics can be weaved.The opening of electronic jacquard machine be needle lifting mechanism be by the actuation of solenoid valve and release come It realizes.Therefore the failure rate of solenoid valve is one of important parameter of quality of electronic jacquard machine.The quality of solenoid valve can influence The quality of tmaterial.
The textile machine company of most of production jacquard uses the above needle module both at home and abroad, but has two with upper module A problem: 1, the domestic method that solenoid valve in electronic jacquard machine needle component is detected not yet.2, the electricity of jacquard The possible problem of magnet valve is since quality problems are blown, and electronic jacquard machine can not judge fault point.
For above-mentioned two problems, common practices is all the component for selecting high quality, by installing again after test of many times, A large amount of fund and time are wasted, and cloth quality cannot be guaranteed.
Summary of the invention
It is an object of the invention to design solenoid valve failure node decision circuitry in a kind of electronic jacquard machine needle component, use It is easy to repair in determination component solenoid valve failure point, reduce maintenance cost.
The technical solution of the invention is as follows:
Solenoid valve failure node judgment method in a kind of electronic jacquard machine needle component, it is characterized in that: using the pipe of CH451 chip Foot scanning function judges 64 way solenoid valve failures of 8 × 8 matrixes, and DIG7~DIG0 pin exports for column scan, SEG7~SEG0 pin all has internal pull down resistor, for row scanning input, in IG7~DIG0 pin SEG7~SEG0 Pin intersection is connected using triode, and solenoid valve failure signal is for providing the base of triode in electronic jacquard machine needle component Pole tension is used on or off triode, generates corresponding signal in IG7~DIG0 pin SEG7~SEG0 pin and turns Become, for judging the position where the fault point of solenoid valve.
When there is solenoid valve failure signal, such as the triode of connection DIG3 and SEG4 is switched on, then works as DIG3 SEG4 detects high level when exporting high level;It is possible thereby to which which way solenoid valve failure judges is, DOUT foot can be with data It is output to host computer.
The driving chip is CH451 or CH452.
Structure of the invention is reasonable, is sentenced using the pin scanning function of CH451 chip (Jiangsu Qin Heng limited liability company) 64 way solenoid valve failures of disconnected 8 × 8 matrixes, and can confirm that fault point position.Can a kind of electronics of on-line checking mention It spends solenoid valve failure in machine needle component and judges malfunctioning node, while generating an interrupt notification controller, and stop in emergency, The failure occurred with system has compared with fast-response.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is that fault-signal generates schematic diagram.
Fig. 2 is solenoid valve failure scanning circuit schematic diagram.
Specific embodiment
Solenoid valve failure node judgment method in a kind of electronic jacquard machine needle component, using CH451 chip, (Jiangsu is oozed perseverance Limited liability company) pin scanning function judge 64 way solenoid valve failures of 8 × 8 matrixes, DIG7~DIG0 pin It is exported for column scan, SEG7~SEG0 pin all has internal pull down resistor, for row scanning input, in IG7~DIG0 Pin SEG7~SEG0 pin intersection is connected using triode, and solenoid valve failure signal is used in electronic jacquard machine needle component In providing the base voltage of triode, it is used on or off triode, is produced in IG7~DIG0 pin SEG7~SEG0 pin Raw corresponding signal transformation, for judging the position where the fault point of solenoid valve.
When there is solenoid valve failure signal, such as the triode of connection DIG3 and SEG4 is switched on, then works as DIG3 SEG4 detects high level when exporting high level;It is possible thereby to which which way solenoid valve failure judges is, DOUT foot can be with data It is output to host computer.
The driving chip is CH451 or CH452.
