Problems solved by technology

[0006] The detection circuit of the above technical solutions is complicated, the cost is high, the production of the device itself is difficult, the reliability is not high, the sensor consumes a lot of power, the peak current is as high as 160 amps, and the number of detection pins is only 2688 pins, which is not easy to expand the number of pins. For more than 5120 pins For electronic jacquard machine testing, new testing methods and testing devices must be considered

Embodiment 1

[0041] FIG. 1 is an electrical schematic diagram of the detection board of the present invention. The detection board 1 is provided with a plurality of parallel-in serial-out shift registers U1-Un and a plurality of detection switches. The parallel-in serial-out shift register is used to realize the function of the parallel-in serial-out sampler in the above-mentioned detection method, and each parallel-in serial-out register has an 8-bit parallel data input port, which can sample the detection switch in 8 positions , where DI is the serial data input line paralleled into the serial shift register, DO is the serial data output line paralleled into the serial shift register, PL is the parallel data latch line paralleled into the serial shift register, CP is the shift pulse clock line that is incorporated into the serial-out shift register, and CE is the shift pulse permission line that is incorporated into the serial-out shift register. Multiple parallel-in and serial-out shift r...

Embodiment 2

[0053] FIG. 3 is a block diagram of the electrical principle of the detection board 1 of this embodiment, which uses a microprocessor MCU as a sampler. The parallel input port of the microprocessor MCU is connected to a position detection switch. The structure of the detection switch is the same as that of the detection switch in Embodiment 1, and will not be repeated here. In addition, the microprocessor MCU is provided with two ports as synchronous signal interfaces, and the serial interface of the microprocessor MCU is used as serial data output. Usually the microprocessor MCU has more ports, but to reach the number of 80 detection switches on one detection board, it is not economical to use a large microprocessor MCU, so choose to use 2-4 smaller MCUs, This is more economical and easier to wire on the test board. Multi-chip MCU obtains the timing signal of each latitude through the synchronous signal interface to control synchronous sampling. Multi-chip MCUs pass the sam...

Abstract

The invention relates to a method for detecting cock of electronic jacquard machine and a detection device using the method. The detection method includes steps: when jacquard needle moves up-and-down, a plurality of samplers with parallel-in series-out and storage function samples information of connection and disconnection for detection switch by connecting the detection switch to bottom of the jacquard needle, the samplers output sampling information, compare the sampling information to correct pattern information and obtain fault information of the jacquard needle. The detection device using the method includes: a control plate, which includes an embedding type microprocessor for receiving position data information of the jacquard needle output from the samplers and a storage mechanism for storing correct pattern data; and a plurality of detection plates, each of which is equipped with a plurality of detection switches and a plurality of parallel-in series-out samplers with parallel data input end connected with detection electrode of each detection switch. The detection device designed by the method is simple and credible, synchronously, due to the way of using the detection plate, the detection device is adapted for cocks with different needle number.

Description

technical field [0001] The invention belongs to the field of textile machinery, in particular to a detection method for a faucet of an electronic jacquard machine and a detection device using the method. Background technique [0002] The traditional electronic jacquard machine faucet manufacturers generally use open-loop control methods such as manual inspection and trial weaving to test their faucets before they leave the factory. The trial weaving work not only takes a long time, but also consumes a lot of manpower. Material resources, and the accuracy is not high. In particular, many problems can only be found during use, which not only brings inconvenience to the user, but also increases the cost of the manufacturer in a disguised form. Therefore, it is necessary to accurately and timely discover the number of wrong needle lifters and their location before leaving the factory. Location.
