A Multi-user Management System Based on Man-machine Interface

Abstract

The invention provides a multi-user management system based on a man-machine interface. The multi-user management system comprises a plurality of sensor modules, a plurality of actuator modules, a PLCcontrol module and an HMI module. The plurality of sensor modules are used for acquiring working state information about target equipment; the PLC control module is used for judging whether the target equipment works abnormally or not according to the working state information; the HMI module is used for sending an operation request signal to the PLC control module according to the operation froman external operator; and the PLC control module is also used for sending a control instruction to the target equipment through at least one of the plurality of actuator modules when the target equipment is judged to have the abnormal working condition or the operation request signal is received.

Description

technical field [0001] The invention relates to the technical field of equipment automatic monitoring, in particular to a multi-user management system based on a man-machine interface. Background technique [0002] Industrial production, especially industrial production related to pharmaceutical production, usually involves many machines and equipment. In order to ensure that these machines and equipment can operate normally during the production process, corresponding management systems are needed to monitor them. At present, some global organizations have provided corresponding automatic monitoring systems, which are usually composed of programmable logic controller PLC and human-machine interface HMI. [0003] In order to facilitate the monitoring and management of the machines and equipment involved in industrial production, there is already a system with relatively complete and advanced functions on the market. This system can provide you with multi-operator access func...

Problems solved by technology

[0004] Although existing automated monitoring systems can provide multi-access and convenient equipment management solutions for industrial production, these automated monitoring systems are complex and expensive, especially for highly restricted production processes such as pharmaceutical production operations. All operations involved in the production process must strictly follow the preset requirements, the entire production process and all key operations performed by operators need to be fully recorded, and the operator’s access level needs to be confirmed before the production process starts, which leads to Its difficult to come up with flexible and convenient solutions

[0005] In addition, technologies such as biometric access control in existing automated monitoring systems are not suitable for the above-mentioned highly restricted environment

It can be seen that the existing automatic monitoring system and its related control technology are not suitable for industrial production monitoring in a highly restricted environment
