Embodiment Construction

[0015] see figure 1 , figure 1 It is a structural schematic diagram of the boiler combustion optimization information transmission control system of the present invention.

[0016] The boiler combustion optimization information transmission control system includes a first industrial computer 10, an AO data collector 20, an AI data collector 30 and a second industrial computer 40;

[0017] The first industrial computer 10 is connected to the AO data collector 20 for obtaining boiler combustion optimization information from the monitoring information system, converting the boiler combustion optimization information into physical signals collected by the AO data collector 20, and transmitting them to The AO data collector 20;

[0018] The AO data collector 20 is connected to the AI ​​data collector 30 through a hardware connection, and is used to transmit the physical signal to the AI ​​data collector 30 through the hardware connection;

[0019] The AI ​​data collector 30 is a...

Abstract

The invention provides a boiler combustion optimization information transmission control system. Boiler combustion optimization information of an SIS is converted into physical signals through a first industrial personal computer, the physical signals can be recognized by an AO data acquisition device, the AO data acquisition device is communicated with an AI data acquisition device at the end of a DCS through hardware wiring, and therefore physical isolation between the SIS and the DCS is achieved. The boiler combustion optimization information is transmitted to a second industrial personal computer in the mode of the physical signals, calculation is performed on the boiler combustion optimization information through the second industrial personal computer to generate combustion optimization control instructions, and then the combustion optimization control instructions are transmitted to a distributed control system through a serial port for combustion control. Hardware wiring is a basic data transmission mode, is a pure physical signal, and can shield abnormal information and guarantee that the safety of the DSC is not influenced. A serial port communication mode has a complete verification mechanism, and therefore the safety of data communication is guaranteed further.

Description

technical field [0001] The invention relates to the technical field of electric boiler operation control, in particular to a boiler combustion optimization information transmission control system. Background technique [0002] To implement boiler combustion optimization technology in power plants, comprehensive performance indicators of boilers are needed as support. The comprehensive performance index information of the boiler is stored in the plant-level monitoring information system (Supervisory Information System, SIS). To send these data to the distributed control system (Distributed Control System, DCS), it is inevitable to link the two systems together. couplet. According to the division of the safety protection system of the power secondary system, the DCS system belongs to the first layer, which is the safety zone I, and the SIS system belongs to the second layer, which is the safety zone II. However, Article 3 of the "Regulations on Security Protection of Power G...
