Accurate monitor and circuits thereof for controller application procedure in production field

Abstract

The invention relates to an accurate monitor and circuits thereof for a controller application system in production field, which can be used for accurately and reliably monitoring abnormal application procedures in real time, such as image collection, system interruption during transmission, image deletion, image transmission failure and the like. The monitor at least comprises four parts, including a conversion interface for data information functions, a standard signal transmission interface, a processing unit for signal collection and comparison and a closed feedback unit. The invention has the main functions of circuit self diagnosis, time detection and monitoring information feedback. The invention mainly comprises a MAX 232 chip, a U3 optoelectronic isolation element, a U4 optoelectronic isolation element, a C5 capacitor, a C6 capacitor, an ATMEGA 8 single-chip computer chip and the like mutually connected. The invention can monitor the application system in real time, and can directly increase accuracy in production control and product information feedback so as to help enterprises to realize intellectual, accurate, sequential and effective management.

Description

technical field [0001] The invention relates to the fields of industrial control such as production and manufacturing, in particular to a device for accurately monitoring application programs of a production field control machine and a circuit thereof. The circuit of the device can monitor the running process of application programs such as image acquisition and image transmission developed based on the industrial computer platform in real time. Background technique [0002] With the development of visual image technology, visual image recognition technology plays a pivotal role in product quality control. At present, more and more enterprises in traditional industries use visual image recognition technologies such as online monitoring and image acquisition to monitor and manage real-time control of products. In actual production, the application of this technology has always been throughout the entire process of product production. However, in the application of this techn...

Problems solved by technology

However, in the application of this technology test, we found that due to the abnormality of the application program, problems such as system disconnection, image loss, and image transmission failure are prone to occur, which poses a great threat to digital management and quality control in the production process. , which lays a hidden danger for the overall development and promotion of real-time detection technology based on industrial computer applications

[0003] Although most of the industrial control machines on the production site have built-in monitoring watchdog timers, most of them are used in non-real-time systems and generally have a long timing cycle, which means that the system is in an open-loop state for a long time and cannot Ensure the safe operation of the system
