According to an aspect of the present disclosure, there is provided a production informatization system.
The production monitoring system 30 is arranged to monitor state parameters of respective computer integrated manufacturing systems 10.
In specific implementation, the computer integrated manufacturing system 10 described here may be further arranged to collect production parameters of respective controlled devices and report them to the manufacturing execution system 20.
According to another embodiment of the present disclosure, at least two computer integrated manufacturing systems control a same production line(s). The production monitoring system 30 is arranged to, after one of two computer integrated manufacturing systems which control the same production line(s) has failed and rebooted, replicate corresponding state parameters of the other computer integrated manufacturing system to the failed computer integrated manufacturing system.
In this way, restoration of parameters in the failed computer integrated manufacturing system is automatically implemented, obviating a need for manual re-introduction of data and reducing labor intensity. As will be appreciated, same production line(s) as used here in embodiments of the present disclosure may refer to two production lines that have same devices and require same parameters to be set for the devices, but not necessarily referring to one and the same production line.
Further, the production monitoring system 30 further comprises a storage module 31 and a monitoring and management module 32. The storage module may be arranged to obtain a correspondence between production parameters and a driving environment for each of the controlled devices.
The monitoring and management module 32 may be arranged to, when the driving environment of a controlled device of the at least one controlled device is changed, acquire from the storage module 31 the production parameters corresponding to the changed driving environment of the driven device, update currently used production parameters with the acquired production parameters, and transmit the acquired production parameters to the computer integrated manufacturing system corresponding to the controlled device.
The integrated control devices in the respective computer integrated manufacturing systems may be further arranged to, upon receipt of the production parameters issued by the production monitoring system, generate corresponding control commands based on the received production parameters and issue the control commands to respective controlled devices.
In specific implementation, “driving environment being changed” described here may indicate that the production state in which a respective production line locates is changed, for example, the external physical and chemical environment, the product model of the product to be produced, etc. are changed. A production parameter described here may refer to a parameter that need to be set for a production device in a respective driving environment. For example, for a robotic device, the corresponding production parameters thereof may refer to walking speed, walking distance, walking time, and so on.
In this way, the production parameters can be automatically updated when the driving environment is changed. In particular, in practical applications, the driving environment of a production line may exhibit a periodical change, at this time the monitoring and management module can read from the storage module the production parameters required for the next period according to a preset period and issue them to a corresponding controlled device.
In another embodiment, the monitoring and management module 32 may be further arranged to automatically obtain from the storage module the production parameters in current driving environment for each of the at least one controlled device after the initialization.
In this way, the production parameters in current driving environment can be automatically introduced into a controlled device that has been initialized. This process involves no manual operation and reduces labor intensity.
In another embodiment, the production monitoring system 30 may be further arranged to acquire and present alarm information that one controlled device of the controlled devices controlled by the respective computer integrated manufacturing systems sends out to another controlled device.
In this way, it is possible to display alarm among devices in multiple production lines involved in the production process, which facilitates the operator's analysis of cause of alarm.
The above embodiments are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not so limited. Any skilled person familiar with this technical field can easily conceive variations or replacements within the technical scope disclosed by the present disclosure, which shall be encompassed within the protection scope of the present disclosure.
