Problems solved by technology

Although there are operating standards, entering data into the system is also a cumbersome manual operation, and human negligence may lead to input errors. Therefore, there is no way to guarantee whether the data recorded manually is accurate.
Moreover, such errors have always occurred in actual production, parameter setting errors, resulting in product scrapping and production loss

Embodiment 1

[0030] refer to figure 1 , which shows a functional block diagram of the signal analysis device proposed in this embodiment. In this embodiment, the signal analysis device includes: a signal replication module and a signal analysis conversion module. Wherein, the signal duplication module is used for receiving and duplicating a VGA (Video Graphic Array, display graphics array) signal. The signal analysis conversion module is used to convert the VGA signal into a USB (universal serial bus) signal.

[0031] Among them, the VGA signal is a common signal used when the host computer outputs to the display. However, each computer in the production equipment has only one VGA signal line. If it is used for external analysis, the display of the production equipment will not be displayed. In order not to affect The VGA data line is transmitted to the display of the production equipment, and the analysis signal can be obtained again. In this embodiment, the VGA signal is copied into tw...

Embodiment 2

[0035] refer to figure 2 , which shows a functional block diagram of the parameter automatic input system proposed in this embodiment.

[0036] Based on the foregoing embodiments, here, a parameter automatic entry system is proposed, such as figure 2 As shown, the parameter automatic input system includes: the signal analysis device and the character recognition device of any one of the above-mentioned embodiments. Wherein, the signal analyzing device is used for acquiring VGA signal and converting it into USB signal. The character recognition device is used to analyze and identify the USB signal converted from the VGA signal, identify the USB signal and obtain equipment production parameters therefrom.

[0037] Among them, without affecting the use of its original equipment, obtain the VGA signal of the equipment, and analyze the VGA signal, and use the programming language such as activating the screenshot function to intercept the currently required USB signal through the...

Embodiment 3

[0054] refer to image 3 , which shows the functional block diagram of the parameter automatic comparison system proposed in this embodiment. Here, in order to analyze the stability of the equipment through multiple sets of data, an embodiment of the present invention proposes an automatic parameter comparison system based on any of the foregoing embodiments, and the automatic parameter comparison system includes: automatic input of parameters in any of the foregoing embodiments A system, a data judging device and an equipment automatic control module. Among them, the parameter automatic input system is used to identify the input equipment production parameters.

[0055] The data judging device (for example, SPC (Statistical Process Control, Statistical Process Control) system) is used to record and analyze the equipment production parameters identified by the automatic parameter input system, and when the equipment production parameters meet the preset standard production pa...

Abstract

The invention discloses a signal analysis device, and a parameter automatic input and comparison system and method, wherein the signal analysis device includes: a signal copying module, used to receive and copy a VGA (Video Graphic Array, display drawing array) signal; The signal analysis conversion module is used to convert the VGA signal into a USB (Universal Serial Bus) signal. In addition, the parameter automatic entry system includes: the signal analysis device described in any one of the above-mentioned embodiments, used to acquire VGA signals and convert them into USB signals; USB signals, identifying the USB signals and obtaining device production parameters therefrom. Therefore, adopting the present invention can identify and automatically record equipment production parameters.

Description

technical field [0001] The invention relates to the field of intelligent monitoring, in particular to a signal analysis device, and a parameter automatic input and comparison system and method. Background technique [0002] At present, general production factories have hundreds of production processes. For older factories, the control computer in the equipment purchased in the early stage does not have data communication functions, and the server cannot control it, so it is necessary to manually select the production parameters of the equipment. , For example, during production, engineers and operators are required to record production data and use data analysis and summary. Although there are operating standards, entering data into the system is a cumbersome manual operation, and human negligence may lead to input errors. Therefore, there is no way to guarantee the accuracy of the manually recorded data. Moreover, such mistakes have always occurred in actual production, an...
