Description

TECHNICAL FIELD

[0001] The present application relates to the field of power plants, and more particularly, to systems, methods and apparatus for archiving operational data in a power plant control system. BACKGROUND

[0002] Power plant control systems, such as distributed control systems (DCS), are mainly used to monitor the operation of a power plant, control the operation of components in the power plant, etc. during the operation of the power plant. The power plant control system includes various devices required to perform automatic control, monitoring, management and archiving operations, which respectively have functions such as receiving operating parameters during the operation of the power plant, completing data acquisition, processing, open-loop and closed-loop control functions; process operation and information collection tasks on the human-machine interface; communication between stations and with other systems through a network; engineering design configuration and debugging; fault diagnosis, etc.

[0003] The power plant control system can generate and store a large amount of operational data during operation. At this stage, users need to query the operational data through a network and an operator station interface. However, such querying is not only inefficient, but also lacks user interaction, especially when the amount of data is significantly increased. This greatly increases the network communication burden of the power plant control system, which poses some hidden dangers to the safe and stable operation of the system.

[0004] Currently, the reading of operational data or historical operational data in the power plant control system is generally achieved in the following ways: (1) directly reading through an operator station in the power plant control system; (2) storing operational data in an external system through a plant information (PI) system interface. However, both of the above-mentioned ways have their own defects. In the first way, due to the limitations of the operator station and system operation burden, users cannot customize the operation according to their needs. In the second way, there are the following problems: (a) when the PI system interface hardware fails, the real-time data transmission characteristics of the PI system can cause time interruption in the external storage process of data, thereby losing data continuity; (b) when a configuration software error of the power plant control system occurs, data reading from the power plant control system can not be completed, resulting in interruption of data storage in the external system; (c) the PI system is usually only used to read and store test data about field control devices, and cannot collect alarm diagnosis information and other data for the power plant control system, so the plant information system interface cannot fully output all operational data of the power plant control system, resulting in loss and incompleteness of the operational data of the power plant control system in the second storage device.

[0005] Therefore, there is a need to efficiently transfer the operational data of the power plant control system from the power plant control system to an external platform or storage device. SUMMARY

[0006] This summary is provided to introduce a set of concepts that are further described below in the of the Invention. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended for use in limiting the scope of the claimed subject matter.

[0007] It is an object of the present application to provide a system, method and apparatus for archiving operation data of a power plant control system to at least partially overcome the drawbacks existing in the prior art.

[0008] According to an embodiment of the present application, there is provided a system for archiving operation data of a power plant control system, the system comprising: a first storage device installed inside the power plant control system and configured to store operation data of the power plant control system; a transmission device configured to: receive a data transmission request for the operation data from a second storage device outside the power plant control system, forward the data transmission request to the first storage device, receive the operation data from the first storage device in response to the data transmission request, and transmit the operation data to the second storage device; and a second storage device outside the power plant control system and configured to receive and store operation data of the power plant control system from the transmission device.

[0009] The system for archiving operation data of a power plant control system according to an embodiment of the present application can conveniently and efficiently transmit and store operation data of a power plant control system to a platform or server outside the power plant control system, thereby reducing the burden of reading and processing operation data in an internal storage device of the power plant control system. In addition, by transmitting the operation data of the power plant control system stored internally to an external storage device, customer experience can be better met and maintenance can be facilitated, thereby reducing costs.

[0010] In one embodiment, the first storage device comprises a network card configured to enable communication between the first storage device and the transmission device based on a TCP / IP protocol. In this embodiment, the network card can be configured to: receive the data transmission request from the second storage device from the transmission device, and in response to the data transmission request, send the operation data stored in the first storage device to the transmission device.

[0011] By using the network card set in the internal storage device of the first storage device or the power plant control system, all the operation data of the power plant control system or the operation data required by the user stored in the internal storage device can be transmitted to the second storage device or the external storage device of the power plant control system, so that all the operation data of the power plant control system or the operation data required by the user can be completely stored in the external storage device and the data is not easily lost during the transmission process.

[0012] In one embodiment, the second storage device comprises a monitor configured to monitor reading, downloading and processing operations on the operation data stored in the second storage device. In this embodiment, when the monitor is locked, the second storage device does not start the data processing software on the second storage device; and when the monitor is unlocked, the second storage device starts the data processing software on the second storage device. In this embodiment, the data processing software can be configured to perform any one or more of the reading, downloading and processing operations on the operation data stored in the second storage device.

[0013] By setting a monitor on the second storage device, the operation performed on the operation data of the power plant control system outside the power plant control system can be made more secure, and the data can be analyzed on the platform or storage device outside the power plant control system, thereby reducing the burden and hidden dangers of directly operating the operation data in the power plant control system.

[0014] In one embodiment of the present application, the transmission device is further configured to perform one-way data transmission with the first storage device and the second storage device.

[0015] By using one-way data transmission, the change of the setting of the internal storage device in the power plant control system can be reduced, and at the same time, the secure access and reading of the operation data of the power plant control system stored in the internal storage device can be realized.

[0016] According to an embodiment of the present application, a method for transferring operation data of a power plant control system is provided. The method comprises: receiving a data transmission request from an external storage device outside the power plant control system, wherein the data transmission request is a request for the operation data of the power plant control system; forwarding the data transmission request to an internal storage device of the power plant control system; receiving the operation data from the internal storage device in response to the data transmission request; and transmitting the operation data to the external storage device.

[0017] In one embodiment, receiving the data transmission request further comprises: receiving the data transmission request periodically or in real time.

[0018] In one embodiment, receiving the operation data from the internal storage device further comprises receiving the operation data by communicating with a network card in the internal storage device. In this embodiment, communicating with the network card in the internal storage device further comprises communicating with the network card based on a TCP / IP protocol.

[0019] The solution of the present application utilizes an intermediate transmission device to transfer all or required operation data stored in a power plant control system to an external platform or storage device of the power plant control system, so as to realize the application function of the data of the power plant control system in the case that the processing of the operation data is separated from the power plant control system.

[0020] According to an embodiment of the present application, a device for transferring operation data of a power plant control system is provided. The device comprises a first receiving module configured to receive a data transmission request from an external storage device outside the power plant control system, wherein the data transmission request is a request for the operation data of the power plant control system; a forwarding module configured to forward the data transmission request to an internal storage device inside the power plant control system; a second receiving module configured to receive the operation data from the internal storage device in response to the data transmission request; and a transmission module configured to transmit the operation data to the external storage device.

[0021] In one embodiment, the first receiving module is further configured to receive the data transmission request periodically or in real time.

[0022] In one embodiment, the second receiving module comprises a one-way receiving module, and the transmission module comprises a one-way transmission module.

[0023] In one embodiment, the second receiving module is further configured to receive the operation data from the internal storage device by communicating with a network card in the internal storage device. In this embodiment, the second receiving module is further configured to communicate with the network card based on a TCP / IP protocol.

[0024] By implementing the method, system and device for transferring operation data of a power plant control system of the present application, all or required operation data in the power plant control system can be transferred to an external storage device or platform (e.g. specified by a user), so that the user can freely query, call and analyze the data on the external platform, to efficiently meet various application requirements of the user for the data, thereby better providing the construction of a digital and intelligent power plant in terms of data application.

[0058] Figure 1 An architectural diagram of a power plant control system (e.g., T2000 system) 100 is shown.

[0059] As Figure 1As shown, the exemplary power plant control system 100 is composed of the following systems: an engineering configuration system 110, a diagnostic system 120, an operation and monitoring system 130, an automation control system 140, and a bus system 150 (e.g., a plant information bus, a terminal bus, etc.), wherein there are editors corresponding to each of the systems 120, 130, 140 in the engineering configuration system 110, through which the configuration and debugging of the functions of the respective systems are implemented.

[0060] In some examples, the diagnostic system 120 is configured to monitor, detect, and locate faults of the devices in the power plant control system, which can help the user to find the source of the faults and prompt the causes of the faults and the methods to solve the faults. The operation and monitoring system 130 serves as a human-machine interface system to help the operator to perform the functions of monitoring the operation of the power plant, data acquisition, calculation, storage, etc., which includes a storage unit server 132 (e.g., a SU server) configured to provide the data storage function for the operation data of the power plant control system. The automation control system 140 is used to perform various tasks in the process control and serves as an interface of the other systems and field devices in the power plant control system. The bus system 150 is configured to connect the above-mentioned systems in the power plant control system and connect the respective systems with the external devices of the power plant control system.

[0061] It should be understood that, Figure 1 It should be understood that the components shown in the

[0062] Figure 2 An architecture diagram of a data archiving system 200 according to an embodiment of the present application is shown.

[0063] In Figure 2 In the example shown, the data archiving system 200 utilizes the server platform in the power plant control system to efficiently output and store some or all of the operation data stored in a first storage device or storage unit server 210 in the power plant control system to an external storage platform of the power plant control system, such as a second storage device 230. In this context, the first storage device 210 can correspond to Figure 1The storage unit server 132 in the power plant control system can be configured to store operating data or historical operating data of the power plant control system. The second storage device 230 can include a data interface server, which can receive data from other devices through a data interface and store the received data. In the example herein, considering whether the storage device is included in the power plant control system, the first storage device 210 can also be referred to as an internal storage device, and the second storage device 230 can also be referred to as an external storage device. In the example herein, the operating data of the power plant control system can include but is not limited to operating parameters, test data, fault conditions, fault causes, alarm information, etc. of the power plant control system.

[0064] like Figure 2 As shown, a network card 212 is provided in the first storage device 210. In one embodiment of the present invention, a slot is provided in the hardware structure of the first storage device 210 to insert the network card 212. In some examples, the network card 212 can be inserted into a peripheral component interconnect (PCI) or PCI-E (PCI Express) slot on the motherboard of the first storage device 210 to realize communication between the first storage device 210 and other devices (such as the transmission device 220). In one embodiment of the present application, the network card 212 can communicate with the transmission device 220 based on the TCP / IP protocol, for example, receiving a data transmission request from the second storage device 230 from the transmission device 220, sending the requested operation data to the transmission device 220 to forward it to the second storage device 230, and so on. Through the interface of the network card 212, data can be transmitted between the transmission device 220 and the first storage device 210. It should be understood that although in Figure 2 Only a single network card 212 is shown in the first storage device 210, but one or more other network cards may also exist in the first storage device 210, and the one or more other network cards can be used to enable the first storage device 210 to communicate with other devices or servers (not shown in the figure) in the power plant control system 200.

[0065] In some examples, a transmission device 220 can be disposed between the first storage device 210 and the second storage device 230 for transmitting signals and data between the first storage device 210 and the second storage device 230. In the embodiments herein, the transmission device 220 comprises a unidirectional transmission device for unidirectionally receiving data (e.g. operation data of the power plant control system stored in the first storage device 210) from the first storage device 210 and unidirectionally transmitting the received data to the second storage device 230, so as to protect the security of data transmission between the first storage device 210 and the second storage device 230. In this context, the transmission device 220 can be connected to the network card 212 of the first storage device 210 via Ethernet through its network interface at one end and connected to the second storage device 230 (e.g. a network card disposed in the second storage device, not shown in the figure) at the other end to serve as a bridge for data transmission between the two. In some examples, the transmission device 220 can be configured as a unidirectional isolation network gateway, e.g. only unidirectionally transmitting data from the first storage device 210 to the second storage device 230, so as to protect the security of data stored in the first storage device 210.

[0066] In this context, the second storage device 230 (e.g. a data interface server) can communicate with the first storage device 210 storing operation data or historical operation data of the power plant control system through the transmission device 220. The second storage device 230 can send a data transmission request for operation data of the power plant control system to the transmission device 220, and receive operation data of the power plant control system from the first storage device 210 through the transmission device 220 and store the received operation data, so as to realize external storage of operation data of the power plant control system.

[0067] In one embodiment of the present application, the second storage device 230 can be provided with a monitor 232. In some examples, the monitor 232 can be implemented in hardware as a "doghouse" to monitor the reading, downloading and processing of data stored on the second storage device 230, such as by controlling the execution of data processing software on the second storage device 230 to ensure the security of the second storage device 230 and the data stored thereon. For example, the execution of the data processing software on the second storage device 230 for the operational data of the power plant control system can be determined according to the status of the monitor 232. In some examples, the data processing software can be initiated when the status of the monitor 232 is unlocked (e.g., a corresponding or correct key is inserted into the hardware doghouse), and the data processing software will not be initiated if the status of the monitor 232 is locked (e.g., no key is inserted into the doghouse or the inserted key cannot unlock the monitor). In other examples, the monitor 232 can use software to ensure the security of the second storage device 230 and the data stored thereon by encrypting the data. For example, the status of the monitor 232 can be determined by verifying the account and password of the data processing software. For example, the status of the monitor 232 can be determined as unlocked when the account and password are verified, and the status of the monitor 232 can be determined as not unlocked or locked when the account and / or password are not verified.

[0068] In the examples herein, the data processing software on the second storage device 230 can be used to perform one or more of the following operations on the operational data of the power plant control system from the first storage device 210: reading, downloading and processing. In embodiments of the present application, the data processing software can implement the listening, reading, downloading and / or processing operations on the operational data of the power plant control system based on the OLE for process control (OPC) protocol. In some examples, the second storage device 230 can implement the external control of the operational data of the power plant control system using the monitor 232 and the data processing software.

[0069] In some examples of the present application, Figure 2 The communication between the first storage device 210, the transmission device 220 and the second storage device 230 shown can be implemented through Ethernet. Although not shown, it is to be understood that, Figure 2 The communication between the various components of the data archiving system 200 shown can also be implemented through other means or networks.

[0070] Figure 3 An exemplary flowchart of a method 300 for archiving the operational data of a power plant control system according to one embodiment of the present application is shown.

[0071] In Figure 3 In the example shown, at step 302, a data transfer request is received from an external storage device external to the power plant control system, e.g., by a transfer device. The data transfer request is a request for operational data of the power plant control system stored in an internal storage device internal to the power plant control system. In the example herein, the operational data can include, for example, but not limited to, operational parameters, test data, fault conditions, fault causes, alarm information, etc.

[0072] At step 304, the data transfer request received from the external storage device is forwarded by the transfer device to the internal storage device of the power plant control system.

[0073] At step 306, after the data transfer request is forwarded, operational data of the power plant control system, e.g., historical operational data, can be received from the internal storage device of the power plant control system. In the example, the operational data is provided in response to the data transfer request from the external storage device.

[0074] In some examples, the operational data is received by the transfer device in communication with a network card in the internal storage device. In the example, the transfer device can communicate with the network card in the internal storage device based on TCP / IP protocol.

[0075] At step 308, the operational data of the power plant control system is transferred by the transfer device to the external storage device for the external storage device to receive and store the operational data, so that a user can read, analyze or process the operational data on the external storage device or external storage platform.

[0076] It is to be understood that the above-described Figure 3 The flowchart of the method shown in FIG. 4 is merely exemplary, and in other embodiments, one or more operations therein can be added, deleted, or replaced.

[0077] Figure 4 A diagram of a device 400 for transferring operational data of a power plant control system according to an embodiment of the present application is shown.

[0078] As Figure 4 As shown, the device 400 can include a first receiving module 402, a forwarding module 404, a second receiving module 406, and a transferring module 408. In some examples, the device 400 can be implemented as a one-way data transfer device.

[0079] In this regard, the first receiving module 402 can be configured to receive a data transfer request from an external storage device external to the power plant control system, e.g., a user's computer or a user's storage platform. Figure 2The first receiving module 402 can be configured to receive a data transmission request from an external storage device (e.g., the second storage device 230 shown in FIG. 2), where the data transmission request is a request for operation data of the power plant control system. In some examples, the operation data of the power plant control system can include operation parameters, fault conditions, fault causes, test data, alarm information, etc. of various systems or components of the power plant control system. In some examples, the first receiving module 402 can be further configured to receive the data transmission request periodically or in real time. For example, by setting a signal sending module of the external storage device to periodically send a data transmission request for operation data of the power plant control system to the first receiving module 402 of the device 400. In other examples, the external storage device can send the data transmission request based on received trigger information (e.g., but not limited to, user input instructions), so that the first receiving module 402 can receive the data transmission request from the external storage device in real time.

[0080] The forwarding module 404 can be configured to forward the data transmission request to an internal storage device (e.g., the first storage device 210 shown in FIG. 2) inside the power plant control system. In some examples, the forwarding module 404 can forward the data transmission request to a network card in the internal storage device via Ethernet. Figure 2

[0081] The second receiving module 406 can be configured to receive the operation data from the internal storage device in response to the data transmission request. In some examples, the second receiving module 406 can include a one-way receiving module, for example, the second receiving module 406 is configured to only receive operation data from the internal storage device, but does not send operation data or any other data to the internal storage device. In examples herein, the second receiving module 406 can receive the operation data of the power plant control system from the internal storage device by communicating with a network card in the internal storage device, for example, based on a TCP / IP protocol to communicate with the network card.

[0082] The transmission module 408 can be configured to transmit the received operation data to the external storage device. In some examples, the transmission module 408 can include a one-way transmission module, for example, the one-way transmission module can be configured to only send operation data to the external storage device but not receive operation data or any other data from the external storage device. In some examples, the transmission module 408 can be a one-way isolated gate for one-way transmission of data.
