The PLC controller 113 is in communication connection with the DCS controller 111 through an optical fiber, the PLC controller 113 collects a major hazard sensor in a place where a major hazard is required, and specifically, the input end of the PLC controller 113 is connected with one or more of a temperature and humidity connector for receiving temperature and humidity signals, a ventilation pressure connector for receiving positive pressure ventilation pressure signals, a carrier gas pressure connector for receiving carrier gas pressure signals, an instrument fault connector for receiving instrument fault signals, an air conditioner fault connector for receiving air conditioner fault signals, and a fire alarm connector for receiving fire alarm signals, open fire signals, and smoke sensing signals.
The DCS controller 111 collects various original signals such as working current values of the combustible gas sensor and the toxic gas sensor, and the DCS controller 111 is connected with monitoring point equipment, namely, the combustible gas sensor and the toxic gas sensor in the industrial gas detector are connected.
The plant level 1 access switch 114 serves as a core device of the plant field data collection module 110 and the field data convergence module 120, and has the characteristics of low cost and plug and play.
With continued reference to fig. 1 and fig. 2, on the basis of the above embodiment, the field data aggregation module 120 includes: at least one PI interface machine 121, a level 2 aggregation switch 122, and a PI server 123; at least one of the PI interface machines 121 is electrically connected to the factory site data acquisition module 110, and the PI server 123 is electrically connected to at least one of the PI interface machines 121 through the 2-stage aggregation switch 122.
Where the level 2 aggregation switch 122 is the aggregation point for multiple plant level 1 access switches 114, it is able to handle all traffic from the plant site data collection modules 110 and provide an uplink to the production data processing modules 130, so the production data processing modules 130 have higher performance, fewer interfaces, and higher switching rates than the plant level 1 access switches 114.
On the basis, the DCS engineer station 112 is connected to the PI interface machine 121 through the enterprise lan, and the DCS engineer station 112 receives the reading request from the PI interface machine 121 and sends the field data to the PI interface machine 121.
The PI interface machine 121 has a plurality of network cards, and the PI interface machine 121 improves both the frequency of data acquisition and the communication quality of the DCS engineer station 112 by applying the OPC communication technology, and is easy to develop and implement, short in development period, and stable in communication.

With continued reference to fig. 1 and fig. 2, on the basis of the foregoing embodiment, the field data aggregation module 120 further includes: at least one unidirectional security gatekeeper 124; the PI interface machine 121 accesses the 2-level aggregation switch 122 through the unidirectional security gatekeeper 124, and the unidirectional security gatekeeper 124 and the PI interface machine 121 are arranged in a one-to-one correspondence.
The unidirectional gatekeeper adopts a feedback-free unidirectional transmission technology to ensure that the absolute unidirectional flow of data from a physical link layer and a transmission layer is ensured, and simultaneously ensures the high reliability, the high fault tolerance, the high security and the high stability of the system.
In this embodiment, the real-time field information of the PI interface machine 121 is verified by the unidirectional security gatekeeper 124 and then collected in the PI server 123 through the level-2 aggregation switch 122, and a unidirectional isolation gatekeeper is installed between the PI interface machine 121 and the PI server 123 to effectively isolate the information management network and the production control network, so as to ensure the network security of the production control network and the stable operation of the production system.
With continued reference to fig. 1 and 2, based on the above embodiment, the field data aggregation module 120 is electrically connected to the production data processing module 130 through the level 3 core switch 160.
