Description
Technical Field
The invention relates to the technical field of automatic monitoring of equipment, in particular to a multi-user management system based on a human-computer interface.
Background
Industrial production, in particular for pharmaceutical production, usually involves a number of machines and devices, which need to be monitored by a corresponding management system in order to ensure that they can function properly during the production process. Currently, some globalization organizations have provided corresponding automated monitoring systems, which are generally composed of a programmable controller PLC and a human-machine interface HMI.
In order to facilitate the monitoring and management of machines and devices involved in industrial production, there are advanced systems with more sophisticated functions, which can provide access functions for multiple operators and HMI solutions at the same time, for example, the monitoring system in US8214455B2 can support HMI for remote viewing and access.
Although existing automated monitoring systems are capable of providing solutions for multiple access and convenient equipment management for industrial production, where these automated monitoring systems are complex and expensive to construct, especially for highly restricted production processes such as pharmaceutical production operations, it is difficult to provide flexible and convenient solutions since all operations involved in the production process must strictly comply with preset requirements, require adequate documentation of all critical operations performed by the entire production process and the operator, and also require confirmation of the access level to the operator before the production process is started.
In addition, techniques such as biometric access control in existing automated monitoring systems are not suitable for the highly constrained environments described above. It can be seen that existing automated monitoring systems and their associated control techniques are not suitable for industrial production monitoring in highly confined environments.
