PLC routine collection
no vote
Application background Programmable logic controller, it uses a kind of programmable memory, used in its internal storage procedures, the implementation of the logic operation, sequence control, timing, counting and arithmetic operations such as user oriented instruction, and through digital or analog input / output control various types of machinery or production process. Key Technology PLC user program can simulate in the laboratory, the input signal with a small switch to simulate, through the PLC on the light-emitting diode can observe the output signal state. After the installation and wiring of the system, the problem of the system is solved by modifying the program, and the debugging time of the system is much less than that of the relay system.. Here are 12 typical routines, can be directly debug run.

The BP network approximation fitting function curv
no vote
Application background The introduction of momentum method makes the large learning rate also have good stability, that is to provide the stability of the optimal weight value during the learning period.. The program can run directly, with results. Key Technology Actual effect of using momentum method is: basically, if previously accumulated changes before and direction implies a single direction, part of the momentum will be accelerated the weight change; if the accumulation of changes is in the opposite direction, momentum will prevent the current changes.

Stock forecast based on cubic index smoothing method
no vote
This paper adopts the cubic exponential smoothing method, which regards every small segment of the stock broken line as an index curve, and carries out the cubic smoothing operation to get a more accurate prediction. The advantage is stable and reliable, but the disadvantage is some lag. The file contains the data used by the program and the running results.

Automatic recognition of 2D code camera based on Halcon
no vote
This code is based on Halcon machine vision software two-dimensional code camera identification code, the camera here is the camera of laptop, because different brands of computers may use different cameras, so before running the code, you need to find the original name of your computer camera head, you can open the camera, click settings options, capture device or Right click "my computer / computer, device manager, image device" to find the name of the camera. Then replace "HD webcam" in my code and run it again.

Halcon camera in the bar code automatic identifica
no vote
This code is based on Halcon machine Visual software of barcode camera recognition code, here of camera is notebook computer since with of camera, because different brand of computer by using of camera may different, so in run code Qian, to first found himself computer camera of originally name, can through "open camera, and click set option, and capture equipment" or right key "I of computer/computer, and equipment management device, and image equipment" two species way find to since with of camera name. Then in my code to be replaced by "HD WebCam" and run it.

Halcon based barcode recognition
no vote
The code without using the camera, but supports many types of barcode recognition, including inverted barcode, each portion of the code has the detailed annotation, recognition accuracy is OK, as long as the image is either too vague or too dark.

QR code recognition based on Halcon
no vote
This code is a two-dimensional code recognition based on Halcon, as long as the images are either too vague or too dark are recognized, but not white red QR code recognition, the QR codes are very rare, of course. Source has detailed notes to explain each part of the parameters and usage.
