DETAILED DESCRIPTION

[0028] In one embodiment, Figure 1-Figure 5As shown, a monitoring and control system for a gas-steam combined cycle unit includes an input box module 10, a distributed integrated management platform 20, an output box module 30, a switch 40, an input end 50 and an output end 60, wherein the input box module 10 is connected to the input end 50, and the output box module 30 is connected to the output end 60; the input end 50 is connected to a gas turbine, a steam turbine, a boiler, an ECS, and a server for sending a song and a command, and the output end 60 is connected to a display screen of a second phase central control room; the input box module 10 includes an input multicast scanning packet monitoring 11, an input multicast data packet 12, and an input response processing function 13; the distributed integrated management platform 20 includes a control end 21, a multicast scanning 22, a response 23, a device queue management 24, a task processing module 25, and a user instruction 26, instruction packaging for multicast 27; the output box module 30 includes an output multicast scan packet monitoring 31, an output multicast data packet 32, and an output response processing function 33; the distributed integrated management platform 20, the input box module 10, the input multicast scan packet monitoring 11 sends the number of monitoring input box modules 10 to the input multicast data packet 12 and the input response processing function 13 and connects to the switch 40; the multicast scan 22 is connected to the switch 40, and the multicast scan 22 is connected to the device queue management 24 with the response 23; the task processing module 25 is connected to the user instruction 26 instruction packaging for multicast 27 and the switch 40; the output box module 30, the output multicast scan packet monitoring 31 and the output multicast data packet 32, the output response processing function 33 and the switch 40 are connected

[0029] A monitoring and control method for a gas-steam combined cycle unit comprises the following steps:

[0030] Step 1: Remote monitoring of power equipment is achieved through a 10-input 10-output platform, where the input terminal 50 is connected to the gas turbine, steam turbine, boiler, ECS, and the server that issues commands, and the output terminal 60 is connected to the display screen of the second phase central control room;

[0031] Step 2: Send the number of monitored input box modules 10 to the switch 40 through the distributed integrated management platform 20, the input box module 10, the input multicast scanning packet monitoring 11 to the input multicast data packet 12 and the input response processing function 13, and connect with the switch 40; connect the multicast scanning 22 to the switch 40, connect the multicast scanning 22 to the response 23 to the device queue management 24, connect the task processing module 25 to the user instruction 26 instruction packaging for multicast 27 and the switch 40, and connect the output box module 30, the output multicast scanning packet monitoring 31 to the output multicast data packet 32, the output response processing function 33 and the switch 40; the user establishes a connection between the input box module 10 and the output box module 30 through the control terminal 21 on the distributed integrated management platform 20 to realize remote monitoring and dispatch multiple operations for distributed management;

[0032] Step 3: Finally, the distributed integrated management platform 20 is used to realize the integrated control of different control systems of the gas turbine power plant, so as to achieve the goal of reducing staff and increasing efficiency while ensuring stable monitoring of the control system;

[0033] like Figure 2 As shown, in order to collect the target computer host display, mouse, keyboard and audio signals, and achieve the goal of split-screen control and remote control, distributed integrated management technology is required. This method is implemented through external hardware encoding and decoding, without the need to install software on the server, meeting the use requirements of the power plant control system, and is compatible with all host software and hardware systems, and the control delay is ≤25ms, which is within the human visual reaction time (50ms);

[0034] The main equipment are:

[0035] 1) KVM sending terminal, used for collecting the display, keyboard, mouse, audio and other signals of the controlled host (operator station) and completing the transmission signal encryption;

[0036] 2) KVM receiving terminal, used for receiving and decrypting the display, keyboard, mouse, audio and other signals of the controlled host (operator station);

[0037] 3) Display, keyboard, mouse and speakers are used for remote display and operation of the controlled host.

[0038] like Figure 5 As shown, the transmitting end and the receiving end are connected by twisted pair or optical fiber, which is completely physically isolated, and the remote operation is only one-to-one configuration and signal encryption measures are taken, so safety is guaranteed.

[0039] From the function of the KVM seat collaboration system, it can be seen that one operator station only needs to add a pair of KVM devices, a monitor, a mouse, a keyboard, an audio device and an appropriate amount of optical fiber to complete the remote operation of the operator station.

[0040] Ultimately, the control room integration is achieved through the KVM seat collaboration system, which ensures the stable monitoring of the control system and achieves the goal of reducing staff and increasing efficiency.

[0041] like Figure 3 As shown in the figure, in order to realize the integrated management of different control rooms, it is necessary to transfer or add the computer in one of the control rooms to another control room. Since the original control room will still need it during the debugging period, this solution is not feasible. Adding all computers to the second control room is not feasible because it involves a wide range of aspects, high technical difficulty and high cost. If only the picture signal, audio signal and mouse signal can be specialized, the integrated management of different control rooms can be realized.

[0042] The present invention controls the input box module and the output box module to establish arbitrary connections through the distributed integrated management platform to realize remote monitoring, scheduling and other operations for distributed management; finally, the integrated control of different control systems of the gas turbine power plant is realized through the distributed integrated management platform, and the purpose of reducing staff and increasing efficiency is achieved on the basis of ensuring stable monitoring of the control system; the monitoring and control method of the gas-steam combined cycle unit improves the reliability and economy of power generation in the power plant, and is worthy of promotion in power plants of the same type.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
