[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] The key terms appearing in the present invention are explained below.

[0027] The CMS (Content Management System) communication protocol defines how data is exchanged between the CMS system and the editor. This protocol involves operations such as retrieving content from the CMS, updating content, and managing user permissions. CMS is a core substation communication protocol independently developed and designed in my country with complete intellectual property rights. It is widely used in substation secondary systems and equipment. For example, a configurable hierarchical distributed heterogeneous protection, measurement, and control device uses the Substation Configuration Description Language (SCL) as a modeling language for data exchange between the protection, measurement, and control device and the gateway.

[0028] SCL (Structured Control Language) is a high-level programming language with syntax similar to PASCAL.

[0029] The method for constructing a CMS protocol server based on the SylixOS operating system provided in the embodiment of the present invention is executed by a computer device. Accordingly, the system for constructing a CMS protocol server based on the SylixOS operating system runs in the computer device.

[0030] Figure 1 is a schematic flow chart of a method according to an embodiment of the present invention. Figure 1 The execution entity can be a CMS protocol server-side construction system based on the SylixOS operating system. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted.

[0031] like Figure 1 As shown, the method includes: Step 110: pre-build an SCL model, wherein the SCL model includes Communication data, IED data, and DataTypeTemplates data; Step 120: Using a configuration file in the SylixOS operating system to configure CMS server parameters, the configuration file includes the file name of the SCL model; Step 130: parsing the SCL model based on the file name of the SCL model in the configuration file, and storing the parsed content in a tree format; Step 140: Apply for the space required for the CMS server to run, and execute the initialization and registration procedures; Step 150: Start the CMS service by calling the service interface and perform service configuration on the CMS service.

[0032] To facilitate understanding of the present invention, the following is a further description of the CMS protocol server construction method based on the SylixOS operating system provided by the present invention based on the principles of the CMS protocol server construction method based on the SylixOS operating system, combined with the process of establishing a CMS service for a protection measurement and control device using the SylixOS operating system in the embodiment.

[0033] The CMS protocol is a core substation communication protocol with fully proprietary intellectual property rights, widely used in substation secondary systems and equipment. Taking a configurable, hierarchically distributed, heterogeneous protection, measurement, and control device as an example, it uses the Substation Configuration Description Language (SCL) as a model language to facilitate data exchange between the protection, measurement, and control device and the gateway. Specifically, the method for building a CMS protocol server based on the SylixOS operating system includes: S1. Construct the SCL model.

[0034] Specifically, the SCL model structure includes: <header>Section: This section is used to identify the SCL file and its historical version information. Each entry in the historical version information can record its version, revision, reason for modification, modifier, modification time and modification content, etc.

[0035] <header> <history> <hitem revision="1.5" version="6.7" when="2021-07-12 10:26:49" who="" why="" what="" / > < / history> < / header> <substation>Part: used to describe the functional structure of the substation. This part is not considered for the protection and measurement and control devices. Substation is not a necessary content and does not need to be constructed.

[0036] <communication>Part, such as Figure 2 This section mainly includes configuration related to IP, MAC, and IP-SUBNET communications. The protection and measurement and control device requires configuration of the station control and process layer subnets. The station control layer includes basic information for networks A and B. The process layer subnet requires configuration of the GOOSE MAC address, VLAN ID, VLAN Priority, APPID, and physical connection information. The physical connection corresponds to the board number and port number in the protection and measurement and control device.

[0037] <ied>Part, such as Figure 3 The figure shows basic information about the protection, measurement, and control device. Logical devices and logical nodes are all contained in the AccessPoint node. Logical devices include common LD, protection, waveform recording, measurement, and control. Logical device LDs include LLN0, common LPHD, alarm signal, GOOSE alarm, device temperature, power supply voltage monitoring, protection function blocking, and time synchronization status self-test.

[0038] <datatypetemplates>Part, such as Figure 4 This section describes the logical node types, including data types and data composition. These can be referenced by logical nodes in IEDs, providing the basis for organizing data in datasets and, in turn, influencing the content of data sent in reports. Logical node types include general LLN0, protection LLN0, measurement LLN0, protection and control LPHD, overcurrent protection, line overcurrent protection, and protection trip.

[0039] S2, based on the SylixOS operating system, the CMS protocol server of the protection and control device is guided by the DL / T860 substation secondary system communication message (CMS) protocol specification, which directly maps the communication service model to TCP / IP. It processes the operation request from the client in a monitoring manner, processes the corresponding data according to the standard, and decides whether to send the message based on the specific operation. In the SylixOS operating system, the server call is made in the form of a library. The process is as follows: Figure 5 shown.

[0040] S201. Pre-configure the server using a configuration file in the SylixOS operating system. The configuration file includes information such as ASDU, APDU, whitelist, SCL file name, whether to enable log and the maximum number of log entries, and file root path.

[0041] S202. Parse the data model according to the SCL file name in the configuration file, and store it in a tree form after parsing. The parsed content includes: communication parameters such as the local IP address. This communication parameter must be consistent with the local content to start normally, otherwise the startup will fail. The basic content of the data set includes telesignaling and telemetering point information. The report control block information includes the data set referenced by the report control block, the triggering method, whether it is urcb or brcb, etc. Control information includes basic control point information, and control mode, etc. Basic information of other control blocks except the report control block. Replacement information includes replacement points, replacement values, etc. In the protection and measurement control device based on the SylixOS operating system, only 1 CPU core is allocated to the server. Therefore, when starting the parsing, the number of threads opened will be reduced to avoid resource exhaustion due to too many threads, making the CPU utilization rate as high as 100%.

[0042] During S203, SylixOS initialization requires application of server runtime space and initialization of variables. User information callbacks, data information callbacks, and association callbacks must also be registered. The user information callback is used for user initialization callback registration, service startup, and exit; the data information callback is used for data read and write; and the association callback is used for client disconnection. During initialization, the device can use the corresponding interface to determine if the startup was successful. The device uses this interface to return information for the next step. If it fails, the fault indicator will illuminate as a warning. The device can also obtain the IED name through the corresponding interface. If a recording file exists, it must be named. The device can obtain / write information corresponding to a reference (a reference mechanism) using the read / write interface and the read data definition interface.

[0043] S204, call the service interface, start the cms service, start the listening service in the service, and listen to the connected client; when the client comes to connect, it is necessary to make a detailed judgment on the basic information of the client to determine whether it is in the whitelist and whether the maximum number of connections has been exceeded. The server starts all basic services, including association services, read and write services, definition acquisition services, reporting services, log services, control services, fixed value services, replacement services, file services, and remote procedure call services. For example, in the reporting service, the server stores the triggering method of the client and sends a report to the client when the established conditions are met. If the data triggering method is data change, and the client turns on the corresponding report control block, a report will be sent to the client when the data changes. In the control service, the server saves and judges the client control mode and control sequence, and when the operation sequence corresponds to the control mode, it sends the corresponding command to the protection and measurement and control device. During the service process, the log information is printed and output to the file. In the protection and measurement and control device based on the SylixOS operating system, the information printing should not be output too much to the terminal.

[0044] S205: Exit the service and release the space applied for by the server in sequence.
