Description
本發明是有關一種穩定控制系統，尤其是可維持工業自動化流程可持續作業不中斷的一種穩定控制系統。 The present invention relates to a stable control system, in particular to a stable control system that can maintain continuous operation of industrial automation processes without interruption.
隨著時代的進步，工業自動化已越來越普及，利用工業電腦或操控設備即可進行有效率的自動化作業流程。然而，在自動化作業流程中，若是監控設備故障，將導致作業中斷，而作業中的產品也可能會因而造成損壞，造成產品報廢的損失。 With the advancement of the times, industrial automation has become more and more popular. Efficient automated operation processes can be carried out using industrial computers or control equipment. However, in the automated operation process, if the monitoring equipment fails, the operation will be interrupted, and the products in operation may also be damaged, resulting in product scrapping losses.
另方面，隨著網路的進步，在工業自動化的生產過程中，可透過遠端伺服器即時傳送作業指令至工業電腦或操控設備，令工業電腦或操控設備可依作業指令進行對應的操控，並即時回報結果供遠端伺服器紀錄數據，並分析判斷是否需調整相關作業參數，再傳送作業指令至工業電腦或操控設備以進行調整。 On the other hand, with the advancement of the Internet, in the production process of industrial automation, the remote server can send operating instructions to the industrial computer or control equipment in real time, so that the industrial computer or control equipment can perform corresponding operations according to the operating instructions, and report the results in real time for the remote server to record data, analyze and determine whether the relevant operating parameters need to be adjusted, and then send the operating instructions to the industrial computer or control equipment for adjustment.
但是，網路傳輸如果發生中斷，也將導致作業中斷，如果仍強行作業，令工業電腦或操控設備在沒有指令與監控的情況下進行，很可能對作業的機台造成不可逆的損壞。 However, if the network transmission is interrupted, the operation will also be interrupted. If the operation is forced, the industrial computer or control equipment will be operated without instructions and monitoring, which may cause irreversible damage to the operating machine.
因此，如何提供一種在自動化作業流程發生監控設備故障時，可及時提供另一備援監控設備接手持續監控，令自動化作業不會因此而中斷，以及如何提供一種在網路傳輸發生中斷時，及時提供另一網路連線，令自動化作業可維持網路連線的狀態下繼續進行自動化作業，而這些都是本案所要著重的問題與焦點。 Therefore, how to provide a method to promptly provide another backup monitoring device to take over continuous monitoring when a monitoring device failure occurs in the automation process, so that the automation process will not be interrupted, and how to provide a method to promptly provide another network connection when network transmission is interrupted, so that the automation process can continue to perform the automation process while maintaining the network connection. These are the issues and focuses that this case will focus on.

本案一種穩定控制系統，是由通訊雙重化處理模組接收主要訊號指令及備用訊號指令，當主要訊號指令傳輸中斷時，切換傳輸備用訊號指令至現場處理裝置，令自動化作業可維持網路連線的狀態下繼續進行自動化作業；以及由電源雙重化處理模組接收主要電壓源及備用電壓源，當主要電壓源中斷時，切換提供備用電壓源至現場處理裝置，令自動化作業不會因斷電而中斷，另方面，訊號雙重化處理模組是供同時控制或接收現場處理裝置訊號，當訊號雙重化處理模組之其中一個故障時，另一個備援訊號模組會持續提供現場處理裝置訊號至中央處理裝置，令此控制系統不會因為電源或網路通訊或訊號之監控設備故障而造成作業中斷。本案具有多組電路組合，可依據不同需求選擇使用對應的電路，而且兼具電路訊號偵測及電路保護，令現場處理裝置得到更安全的用電保護，並達成上述所有目的。 The present invention relates to a stable control system, wherein a communication duplex processing module receives a main signal command and a backup signal command, and when the main signal command transmission is interrupted, the backup signal command is switched to be transmitted to the field processing device, so that the automation operation can continue to be performed while maintaining the network connection; and a power duplex processing module receives a main voltage source and a backup voltage source, and when the main voltage source is interrupted, the backup voltage source is switched to be provided. The voltage source is sent to the field processing device, so that the automation operation will not be interrupted due to power failure. On the other hand, the signal duplex processing module is used to simultaneously control or receive the field processing device signal. When one of the signal duplex processing modules fails, the other backup signal module will continue to provide the field processing device signal to the central processing device, so that this control system will not be interrupted due to power supply or network communication or signal monitoring equipment failure. This case has multiple circuit combinations, and the corresponding circuit can be selected according to different needs. It also has circuit signal detection and circuit protection, so that the field processing device can be more safely protected and achieve all the above purposes.
