Description

Telesignaling configuration rapid checking system and method for telemechanical device

Technical Field

The invention relates to the technical field of telesignaling configuration quick check of telesignaling devices, in particular to a telesignaling configuration quick check system and method of a telesignaling device.

Background

The intelligent substation data communication gateway machine (namely a telecontrol device) is used as important station control layer equipment, communicates with lower and inter-station layer equipment, carries out telecontrol information real-time interaction with upper and all levels of control centers, provides data, model, graph and file transmission service for a main station system to realize functions of substation monitoring control, information inquiry, remote browsing and the like, is key equipment for supporting an intelligent substation to realize integrated operation of regulation and control, and is important for safe and stable operation of a power grid. The method is mainly used for debugging the intelligent substation monitoring system engineering, and the remote control device is also briefly described as 'information point alignment' in the engineering.

At present, the joint debugging of the regulation and control information of the telecontrol device mainly depends on manual work between a main station end and a plant station end through a real-time communication mode, namely, the information received by the main station end and the real-time information sent by the plant station end are corrected in a manual one-by-one point-aligning mode. The technical means of the method is single, an effective debugging tool is lacked, the automation degree is low, and a large amount of manpower and time are consumed. In order to improve the engineering debugging implementation efficiency, improve the automation level of debugging work and develop the research of telecontrol information intelligence and quick check technology, the research is imperative.

At present, in the engineering debugging stage of an intelligent substation monitoring system, due to the loss of technical means and debugging tools, telecontrol information joint debugging work often generates a certain signal in a substation according to the content in a regulation and control information corresponding table by a plant station end debugging worker, a master station end worker receives alarm information with a certain 104 address as an identifier at a remote dispatching master station, and the master station and the plant station communicate in real time whether the sent and received signals are consistent or not to check whether the forwarding configuration of the signal in a telecontrol device is correct or not. Such debugging modes need to be checked one by one, and the master station and the plant station staff need to keep communication all the time, so that a large amount of manpower and time are consumed, and the actual signals are sent by depending on devices such as field protection, measurement and control and the like, so that conflicts with other debugging works of the plant station are often generated, and the checking result is influenced. Therefore, at present, the information joint debugging work needs to be carried out after other debugging works in the station are basically finished, the debugging period is very short and debugging personnel are easy to miss the debugging work and is often arranged at the final stage of engineering debugging.

Detailed Description

The invention is further described below with reference to specific examples.

The intelligent substation monitoring system needs to acquire a large amount of equipment running state information including primary equipment state data, secondary equipment state data and auxiliary equipment data. The data are sent to station control layer equipment, such as a monitoring host, a telecontrol device and the like, by a bay layer IED (intelligent electronic device) such as a protection device, a measurement and control device and the like in an MMS (multimedia messaging service) message mode. After receiving the MMS message, the telecontrol device transmits the MMS message to a remote dispatching master station in a 104 message mode through a special power data network according to a 104 forwarding table configured in the device. This process is the "remote signaling" function of the basic "four remote" function, which is schematically shown in fig. 1.

The information quantity in the intelligent station can reach tens of thousands, and the scheduling master station does not need all the information. Usually, the personnel of the master station scheduling will select 1 or several pieces of information in the station, and after one-to-one or many-to-one merging, 1 regulation information point is formed and identified by a unique master station information object address (also called 104 address). All the control information points are summarized to form a control information corresponding table of the whole station, and the control information corresponding table is generally presented in an Excel format. Usually, the number of 104 addresses allocated to the remote signaling function by 1 500kV intelligent substation reaches thousands or even tens of thousands, while the number of 104 addresses of the remote control and remote measurement functions only accounts for hundreds. Therefore, in the regulation information correspondence table, the proportion of the 'remote signaling' part is the largest, and the checking work configured on the part is the key point of the telecontrol information joint regulation work and is also the problem which is mainly solved by the rapid checking technology provided in the text.

Table 1 intercepts the "remote signaling" part of the typical control information mapping table, and the displayed content shows the association relationship between the 104 address and the information in the corresponding station. The manufacturer engineering personnel of the telecontrol device performs forwarding configuration on the telecontrol device according to the regulation and control information corresponding table, and the essence of the operation is that 104 addresses are associated with data paths of one or more DO objects in the SCD (total station system configuration file) of the transformer substation. At present, the work needs manual configuration of telemechanical manufacturer engineering personnel, a corresponding automatic configuration technology is lacked, and due to the fact that the data volume is large and the condition that a plurality of pieces of in-station information correspond to one 104 address exists, configuration errors such as association errors, missing configuration, multiple configuration and the like cannot be avoided. The key point of the telecontrol information joint debugging work is to verify whether a 104 forwarding table in the telecontrol device is configured correctly, namely whether the 104 address is associated correctly with a DO object data path in a SCD file of the transformer substation.

TABLE 8 typical regulatory information corresponds to the TABLE "REMOTE SIGNALING" section

In view of the above problems, the present invention provides a technology for rapidly configuring remote signaling of a remote control device of an intelligent station in embodiments 1 and 2, which relies on a relatively mature universal IED simulation technology based on the IEC61850 standard and is implemented by utilizing communication protocols such as MMS and IEC 104.

Example 1: as shown in fig. 2 to 3, a remote signaling configuration fast checking system for a remote control device includes an IED simulation tool, an analog master tool, and a multi-data source offline processing tool, wherein the IED simulation tool is connected to a monitoring back-end, the remote control device, and the multi-data source offline processing tool, and the analog master tool is connected to the remote control device and the multi-data source offline processing tool. It is seen that the technical scheme relates to a plurality of data sources of simulation tool record files, monitoring background record files, simulation master station record files and a regulation and control information table, wherein f1, f2, f3 and f4 are used for representing the 4 files, and d1, d2 and d3 are used for representing information description of a certain piece of information in f1, f2 and f 4. Analyzing the description elements of the information in f1, f2, f3 and f4 can find that all files can be concatenated by two elements with uniqueness, i.e. the SOE timestamp and the 104 address. The concrete links are shown in fig. 2.

The basis of all the work is the regulation and control information correspondence table (i.e. f4 file). Taking a certain piece of information as an example, starting from f4, finding the position of the same 104 address in f3 according to the 104 address in f4, and determining the SOE time of the piece of information; and further finding the information record of the same SOE time in f1 and f2 according to the SOE time, so that d1, d2 and d3 of the same 104 address and the information of the same SOE time in f1, f2 and f4 can be extracted and checked and judged.

Because the description of the object is not standard when the integrator makes the SCD file, the description of the monitoring background database measuring point is manually input, and the like, the description of the same signal can be different among the three parts of d1, d2 and d 3. In the traditional mode of the joint debugging work of the regulation and control information, a debugging person judges whether the forwarding of the telecontrol device is correct or not by manually judging whether d2 and d3 represent the same meaning or not.

If d2 and d3 in a record are determined to represent the same meaning, it indicates that the 104 address of the record is correctly associated with the data path of the DO object in the SCD, which is the core of the telecontrol information coordination work.

As a simple example, according to a debugging report output after a certain test, it can be seen that the description of d3 and d2 does not correspond to the point with the address of 104 being 233, which indicates that the telecontrol device has a mismatch to the point; and the point with the address of 234 of 104 should have 2 pieces of in-station corresponding information according to the regulation and control information table, but only one piece of in-station information is related through test, and the condition of missing distribution exists. Similar situations need to be found in the checking of telesignalling configurations for telematic devices, and these incorrectly correlated situations should be fed back to the telemechanical device manufacturer engineer to be modified.

The IED simulation tool sends MMS messages to the monitoring background and the client side of the telecontrol device through a station control layer network by simulating an MMS server side of an IEC61850 protection and measurement and control device, the IED simulation tool comprises a simulation operation module, an operation management function module and a model analysis function module, the simulation operation module is connected to the client side through an MMS network communication module, and the operation management function module is connected to the simulation operation module and the model analysis function module. Simulation tool design framework referring to fig. 3, the implementation method of the IED simulation tool includes the following steps:

(1) importing and analyzing an SCD file, checking the legality of the file, analyzing a model file, constructing a data model required by simulation according to Q/GDW 1396-;

(2) the simulation operation management function module enables the simulation process to be developed in a manual test or automatic test mode, the automatic test mode mainly realizes the point-by-point transmission of the total station information, namely a panoramic information scanning mode, and ensures that all signals analyzed by the model are automatically marked with tools, unique and special SOE time is sequentially moved once by the displacement setting of total variation 0, total variation 1 or self-resetting variation (firstly variation 1 and then variation 0); the manual test freely configures a test strategy to meet the operation requirements of single-point test, multi-point test, batch processing and manual definition of SOE time;

(3) the simulation operation management function module imports an actual mapping table formed after an off-line checking process of total station remote signaling configuration, and provides technical support for on-line checking with a real remote scheduling master station at a later stage;

(4) the simulation operation module enables the message output of the simulation tool to send messages according to the customized requirement according to the sending strategy set by the operation management function module, and the messages are continuously sent at set time intervals (such as 30 ms);

(5) the MMS network communication module ensures normal MMS communication between the simulation tool and the client according to the communication service standard in IEC 61850;

(6) the simulation tool records all MMS interactive processes and generates a simulation tool record file.

The IEC104 simulation master station tool mainly realizes the function of simulating a remote dispatching master station, supports the current mainstream power telecontrol protocol (such as DL/T6345104-2009 part 5-104 of telecontrol equipment and a system, namely IEC60870-5-104 network access of which the transmission protocol adopts a standard transmission protocol subset), has the functions of message analysis and record storage, and can analyze 104 messages sent by a telecontrol device in real time and store 104 address and point number displacement conditions as a simulation master station record file.

The multi-data-source off-line processing tool is a brain of a debugging system, and is used for realizing association and analysis work among simulation tool record files, monitoring background record files, simulation main station record files and a regulation and control information table issued by a regulation and control center, which are generated in the debugging process.

The off-line processing tool with multiple data sources can automatically output two documents, one is a debugging report, the report shows 104 addresses, the content of three information descriptions d1, d2 and d3 of a certain piece of information in a simulation tool recording file, a monitoring background recording file and a regulation and control information table and the machine judgment result of the matching degree of the machine on the three information descriptions d1, d2 and d 3; the other is the actual mapping table, where 104 addresses and data paths (references) of corresponding signals are presented; the debugging report is used for engineering debugging personnel to review, serves as a basis for modifying the error configuration in the telemechanical device, can also synchronously find the description error or default problem of the 61850 object in the SCD file, helps an integrator to complete SCD in time, and leads the actual mapping table into an IED simulation tool, so that convenience is provided for later-stage auxiliary online information joint debugging work.

Example 2: a telesignaling configuration rapid checking method of a telemechanical device based on panoramic information scanning comprises the following steps: acquiring actual forwarding relations configured in a complete telecontrol device by a panoramic information scanning mode, finishing checking work by judging whether the forwarding relations are consistent with contents in a regulation and control information corresponding table, theoretically, one-time displacement of a plant station end DO object can trigger one-time corresponding 104 information transmission through the telecontrol device, acquiring all telecommand signals of the plant station end by reading an SCD file, simulating signal displacement generated one by one within an interval of 10-50 ms, namely signal displacement from a part position to a part position and then from the part position to the part position, sending total-station MMS information with a specific SOE (event sequence record) time scale to the telecontrol device and a station monitoring background, recording, closely associating data of different data sources by utilizing uniqueness of factors of SOE time and 104 point number, presenting configuration association of 104 addresses in the telecontrol device and DO object data paths in a corresponding 61850 model file, and associating the information in the corresponding station in the regulation and control information corresponding table with the alarm information description actually presented by the monitoring background, and further judging whether the configuration of the telecontrol device is correct or not through consistency check.

A telecontrol device remote signaling configuration rapid checking method based on panoramic information scanning realizes closed-loop debugging of an offline rapid checking process of total station remote signaling configuration in a telecontrol device, and comprises the following specific steps:

(1) an IED simulation tool is adopted to simulate a required data model by importing an SCD file, preprocessing is carried out, and all remote signaling signals of the total station are determined;

(2) an IED simulation tool is adopted to send MMS messages with specific SOE time scales to a monitoring background and a telecontrol device as required through a station control layer network, namely panoramic information scanning is realized during a total station test;

(9) the off-line processing tool with multiple data sources gives an actual mapping table of the telecontrol device which is tested and verified;

(10) the actual mapping table can be led back to an IED simulation tool, and support is provided for online checking between the later station and the dispatching master station.

Example 3: as shown in fig. 4-14, the simulation master station tool includes a message receiving module, a message analyzing module, a message simulation sending module, a communication module, a message storage module, and a human-computer interaction interface; a message receiving module: the IEC104 message sent by the remote mobile is received through the communication module, the message is classified and stored by using a corresponding data structure, and the IEC104 message can be sent to the message analysis module for message analysis, or the original message is stored in an IEC104 message storage library; a message analysis module: classifying and analyzing the IEC104 messages, displaying original messages and message meanings represented by each byte of each original message through a human-computer interaction interface, and finally enabling information values in the analyzed IEC104 messages to correspond to a transformer substation table and transmitting the information values into an IEC104 message storage library to generate a master station point-to-point table; a message simulation sending module: the messages such as time synchronization, general calling, remote control, remote regulation and the like sent by the telecontrol machine are sent; a message storage module: storing the original IEC104 message and the analyzed IEC104 message in real time, classifying, searching, comparing and analyzing the messages according to the type and time mode of the historical messages, and generating a master station peer-to-peer table; a communication module: establishing TCP/IP connection with the remote controller to realize the receiving and sending of IEC104 messages; a human-computer interaction interface: and providing a man-machine interaction interface, displaying functions of each module in a centralized manner, reading message information received and sent and content of message analysis by a tester through the interaction interface, and searching historical messages by calling an IEC104 storage library. The simulation master station tool has the function of 104 client sides, can receive and analyze remote measuring and remote signaling messages sent by the data network shutdown device and the spacer layer device, sends remote control commands and simultaneously records the test process.

The method for realizing the message receiving module of the IEC104 master station comprises the following steps:

according to the IEC60870-5-104 specification, the communication between the dispatching master station and the telecontrol equipment is divided into two modes of peer-to-peer communication and master-slave communication. The simulated IEC104 master station designed by the invention is used as a client, and the telecontrol machine is used as a server for network communication, so that the IEC104 message between the simulated IEC104 master station and the telecontrol machine can be received and transmitted.

The invention realizes network programming by relying on a QT platform, and QT provides two categories of QTCPsocket and QTCPServer. Respectively for implementing a client and a server of TCP. The QTCPSocket and the QTCPserver indirectly inherit QIODevice, and can use QDataStream and QTextStream to read and write network data. The QT is programmed in the network using a signal-to-slot messaging mechanism, and a connection () function of QObject class associates signals with slots. The self-defined slot function responds to connected (), disconnected (), readyRead () signals provided by QTCPSocket. The slot function is shown in table 1.

TABLE 1 signals and corresponding custom slots

Slot function	Signal	Functional description of functions
			voidonConnectTCP()	connected()	Responsive to TCP connection success
onDisconnectTCP()	disconnected()	Responding to TCP connection failures
			VoidonTcpReady()	readyRead()	Responding to receiving a new data message

The implementation process of simulating the IEC104 master station as the client to perform network communication is shown by the following codes: firstly, creating a corresponding instance object by using a QTCPSocket class; secondly, configuring a network port and an IP address, wherein the port number specified by IEC104 is 2404; calling a QTCPSocket class object to call a connectToHost () function to connect a server; the Connect () function associates a signal with a slot; and finally, the QTCPSocket class object calls a closed connection () function to close the TCP connection.

If the TCP connection is successful, the QTCPSocket object sends a concatenated () signal; if the connection fails, the QTCPSocket object sends an error () signal; when the client receives the data, the QTCPSocket object sends a readyRead () signal; when an error occurs in the connection process, the QTCPSocket object sends out a disconnected () signal. And after success, adding corresponding functions in the slot functions corresponding to the connected/error signals to realize TCP connection.

After the client is successfully connected with the server, when receiving data, the user-defined slot function onTcpReady () receives a readyRead () signal sent by the QTCPSocket object. The write () function of the QIODevice class is called in the onTcpReady () function, and the read () function reads and writes data with the server. In order to ensure that the IEC104 data block can be transmitted completely, the data type is quick 64.

IEC104 message parsing

The IEC104 message is composed of data frames in three formats, I frame, S frame and U frame. The lengths of the U frame and the S frame are fixed, and the structure is simpler. An I-frame is a data frame containing application data units, and its length is variable and its content is complex. When the IEC104 message is analyzed, the three messages are classified and analyzed, and the complex I frame structure is stored by using the corresponding structure body, so that the method is gradually simplified and the analysis is finally completed.

IEC60870-5-104 application protocol data unit structure

The IEC60870-5-104 message data model is derived from the open systems interconnection model ISO-OSI, telecontrol equipment and the 5 th-104 th part of the system: the transmission protocol specifies that the IEC60870-5-104 data frame has only three layers, which respectively correspond to a physical layer, a link layer and an application layer in the network ISO.

The IEC60870-5-104 application data structure unit APDU corresponds to an application layer in network transmission and is composed of application protocol control information APCI and an application service data unit ASDU. The basic Application Protocol Data Unit (APDU) has two forms, one consisting of only an APCI and the other consisting of one APCI and one or more ASDUs. The APCI takes 6 bytes, has a fixed structure, and consists of a start character 68H, an APDU length and 4 control fields. The application protocol data unit APDU structure is shown in figure 5.

Application protocol control information APCI: the IEC60870-5-104 application protocol control information APCI consists of a start character 68H, an APDU length, 4 control fields.

(1) The first byte start character 0x68 is converted to decimal 104, which indicates that the transmission message is an IEC104 message.

(2) The second byte is the length of the APDU, and the length of the APDU except the first two bytes is the sum of the lengths of the control field and the ASDU. An APDU length of the IEC60870-5-104 message is specified to be 255 bytes or less, so the value range of the APDU length should be 4-253.

(3) The four control domains occupy four bytes in total, and the control domains contain control information of message receiving and sending so as to ensure that the messages are not lost and retransmitted, and also contain control information of the messages, such as message transmission starting and stopping, message link test and the like. According to the different meanings and formats of the control domain, three general different types of message formats are defined. Which are respectively as follows: information Transmit Format (no number control function Format frame), U frame, number super function functions, S frame.

The U frame has a control function, and the control station controls the slave station to perform message transmission through U (STARTDT) (starting data transmission) and U (STOPDT) (stopping data transmission). And meanwhile, when the message transmission of the two stations reaches the maximum no-load timeout time t3, the control station performs a link test by starting U (TESTFR). The U frame is a frame with a unnumbered format, and the function of counting the received and transmitted messages cannot be realized. Fig. 6 shows a U-frame control field format.

The I frame message is used for ASDU information transmission, the I frame definition control field is formed by a message sending sequence number and a message receiving sequence number, and fig. 7 is an I frame format.

The S-frame message has a number information monitoring function. The S-frame definition is determined by whether the 1 st bit in the first octet control field is a1 and whether the 2 nd bit is a 0. Fig. 8 shows the S-frame control field information, which only contains APCI data.

Application service data unit, ASDU: according to the above description, only the I-format frames in the IEC104 message have ASDUs. The I-frame message data frame application service data unit, ASDU, is composed of a data unit identity, one or more bodies of information, and its general structure is shown in fig. 9.

The data unit identifier includes a type identifier, a variable structure qualifier, a transmission reason, and an information public address, and the following describes the above four types of identifiers.

(1) Type identification

The type identifier identifies the ASDU type of the IEC104 message, which occupies one byte. The message analysis function of the IEC10104 master station module is simulated in the invention, mainly aiming at the process information transmitted from the substation to the master station, the process information transmitted from the master station to the substation, the system information in the monitoring direction from the substation to the master station and the system information in the control direction from the master station to the substation, wherein the information of the four aspects is listed in Table 2. The 104 analog master station message parsing module realizes parsing of the ASDU type message information in table 2.

TABLE 2 ASDU types of IEC104

(2) Qualifier with variable structure

The variable structure qualifier occupies one byte, 1-7 bits represent the number of information bodies, the highest bit represents the arrangement mode of the information bodies, SQ is 1 represents that the information bodies in the ASDU are continuous, and the address of the former information body is added with 1 to obtain the address of the latter information body. SQ of 0 means that the information body in the ASDU is discrete, each information object address to be identified in the information body.

(3) Reason for transmission

The transfer reason takes two bytes. Wherein the first byte is a transmission reason, and 1-6 bits are a transmission reason identifier; the 7 th bit P/N is 0, and 1, a positive acknowledgement and a negative acknowledgement. The highest bit T indicates whether or not the test is performed, T is 0 indicating that the test is performed, and T is 1 indicating that the value is not in the test.

The second byte represents the source address, which represents the master address of the message response and is rarely used. The case not generally used sets it to 0.

(4) Information public address

The information public address occupies two bytes, the most significant byte is 0, the public information address is stored in the low-significant octet, and the range of the public information address is 0-255.

The application data service unit, ASDU, body of an I-frame typically consists of three parts, a body address, an information element and a body time stamp. The body address typically takes 3 bytes. When the number of information bodies is more than 1, the composition forms are divided into two types: one is that the address of the information body is continuous, only the first information body has the address of the information body, the other information bodies do not contain an item of the address of the information body, the address of the information body is obtained by adding 1 to the address of the information body; another is the address discretization of the information bodies, in which case each information body should contain the address of the information body.

IEC104 message parsing is realized: the IEC104 message analysis implementation is divided into two steps, firstly, when an IEC104 simulation master station serves as a client to receive an IEC104 message sent by a telemobile, a readyReady () signal is sent out, and a self-defined slot onTcpReady () receives the signal. At this time, the remote mobile uploading IEC104 message is stored in the self-defined structure IEC _ APDU in the function ontTcpReady (). Then, frames in different formats corresponding to IEC104 are classified, different parsing functions are called for the frames in different formats, and parsing is finally completed.

(1) Structure IEC _ APDU

The format of U frame and S frame in IEC104 message is simple and only has APCI part, and APCI has the same sequential structure. The I frame has an application data unit (ASDU) besides the APCI, the number, the length and the content of information bodies of different types of ASDUs are greatly different, and the storage of various types of message information of the IEC104 by using a uniform structure body has certain difficulty. However, if a plurality of structural bodies are adopted to define each type of IEC104 messages, the analysis process is complicated, and the speed during analysis is also affected. When the structure IEC _ APDU is designed to store the IEC104 message, the idea of a complex is adopted, so that different types of data frames can be stored in the structure.

And filtering other data frames except IEC104 by the length of the APDU of the message header and storing the IEC104 data frames in the structure IEC _ APDU. The specific storage process is as follows: after TCP connection is successful, defining a structural body IEC _ APDU object, storing IEC104 data frames into the IEC _ APDU one by using a read () function in QTcp Socket, firstly, storing a message header into the APDU-start to judge whether the message header is 0x68 or not, if so, storing a second byte of a continuous message into the APDU, and if not, returning to carry out a new round of reading the message continuously. Length, whether the length is less than 4 is judged, if so, a new round of message reading is returned, and otherwise, the rest data frames of the IEC104 message are read into the IEC _ APDU, as shown in fig. 10.

The ASDU data identification units of different I frames have the same composition sequence, the invention defines a structural body IEC _ ASDU _ TYPE, which comprises an I frame ASDU data identification unit, which is defined as follows:

(2) ASDU information body structure

The reason why the structure of the ASDU of the I-frame is complicated is that the body addresses are divided into discrete and continuous, and the length and content of the information elements are different. The following describes the information structure and content of the ASDU of the I-frame, and further describes the design process of IEC104 message storage data structure IEC _ APDU according to the present invention, for example, for the single-point information (type identifier < 1 >: M _ SPNA 1).

The single-point information body is divided into a discrete type and a continuous type, and the table 3 shows a single-point information ASDU structure with a discrete information body address and SQ being 0. Table 4 shows a single-point information ASDU structure in which SQ is 1 and the information body addresses are consecutive. Each body in table 3 is composed of two parts, an information address occupying three bytes and an information element occupying one byte. The first information body in table 4 is composed of an information address and information elements occupying 3 bytes, the following N-1 information bodies are composed of only N-1 information elements, and the information address is obtained by adding one to the previous information address.

TABLE 3 SQ-0 discrete ASDU

TABLE 4SQ ═ 1 continuous ASDU

Each bit of the information element is defined as follows:

first SPI: 0-1, 0, OFF, 1, ON;

the second to fourth bits are fixed values of zero;

the fifth bit BL is < 0-1 >, < 0 >, < 1 >, < i;

the sixth position SB < 0-1 >, < 0 >, < 1 ═ substituted

The seventh position NT < 0-1 >, < 0 >, < 1 ═ nonce

Eighth bit IV < 0-1 >, < 0 >, < 1 ═ valid

Different types of ASDUs are identified by ASDU first bytes, and have different information elements, and the length and the content of the information elements are different, so that the same structural body is difficult to define uniformly. In the process of implementing message analysis, the information elements of different TYPEs of ASDUs are respectively defined by different structural bodies, for example, the information element of single-point information is defined by the structural body IEC _ TYPE1, the information element of double-point remote signaling is defined by IEC _ TYPE3, the information element of step information is defined by IEC _ TYPE5, and the like. The types of the ASDUs used for simulating the IEC104 master station software module are described above, and the structure body for the information elements is defined in the present invention. The following are structural bodies corresponding to the information elements of the single-point information, and parameters in the structural bodies correspond to the content of the single-point information elements one to one:

the variables of start, length, NS and NR in the IEC104 message storage structure IEC _ APDU defined by the invention correspond to a header, an ASDU length, an order sending and an order receiving in sequence according to the composition order of APCI in the APDU; the data type IEC _ ASDU in the IEC _ APDU is the ASDU data unit identification part defined by the invention; the complex SQL part of the IEC _ APDU corresponds to the body part of the I-frame ASDU. The composition of the structure IEC _ APDU is as follows:

struct IEC_APDU

{

an unscented char start; // header

An unused char length; length/length

An unscented shortNS; // sequence of formation

An unscheduled shortNR; // harvesting sequence

struct IEC_ASDU asduh；

union SQL{

struct{

unsigned short ioa16；

unsigned char ioa8；

iec _ type1 obj [1 ]; // iec _ type1 is a single-point remote signaling information content-corresponding structure

Sq 1; continuous single-point remote signaling

struct{

unsigned short ioa16；

unsigned char ioa8；

iec_type1 obj；

}nsq1[1]；

struct{

unsigned short ioa16；

unsigned char ioa8；

iec_type3 obj[1]；

}sq3；

struct{

unsigned short ioa16；

unsigned char ioa8；

iec_type3 obj；

}nsq3[1]；

struct{

unsigned short ioa16；

unsigned char ioa8；

iec_type60 obj；

Nsq 60; // remote control information

unsigned char dados[255]；

iec_type107 asdu107；

}。

The omitted part of the IEC _ APDU complex SQL is a structure body corresponding to the information bodies of different types of ASDUs. The invention defines the information body elements according to different information identifiers as different data structures-the structure IEC _ TYPE1 introduced above represents a single-point telecommand information content. The invention defines a powerful data structure IEC _ APDU, and stores ASDUs of different types by using the structure when reading I frame messages.

The IEC _ APDU is characterized in that the united body SQL in the structural body is dynamically allocated with the memory according to different storage variables, and when different types of ASDUs are stored, the information can be respectively stored in the corresponding structural bodies.

The structure analyzes discrete single-point remote signaling and continuous single-point remote signaling respectively. When discrete single-point remote signaling SQ is stored as 0, each information body of the discrete single-point remote signaling consists of an information address and information content, when the IEC _ APDU structure is called to store the information body, the association allocates memory according to the reality, at the moment, the association actually uses the structure array nsq1[ ] to store each discrete information body, and each array element nsq1[ ] contains a high address bit ioa16, a low address bit ioa16, a IEC _ type1 type variable obj, and corresponds to the information body address and the information element of one discrete single-point remote signaling information body respectively.

When storing the continuous single-point remote signaling SQ1, the complex actually performs memory allocation, and at this time, the complex actually stores the continuous information using the structure SQ 1. Ioa16 and ioa8 of the structure sq1 correspond to the information address of the first information body of the continuous single-point information, and the array obj [ ] of the iec _ type1 type corresponds to N information elements storing the continuous information bodies.

(3) U-frame, S-frame parsing

The U-frame, S-frame module control field is the 3 rd byte position of the APCI, including control information (V-validate (activate) C-acknowledge), command (TEST-TEST STOP-START). U, S analyzing frame, judging the value of first IEC _ APDU- > NS of control domain, outputting analyzed message information when the message received by the simulating master station is request start frame and test frame, sending confirmation request frame and link confirmation frame to the sub station for confirmation, and ending message analysis. And outputting the analyzed message information in other cases, and ending the analysis of the message, as shown in fig. 11.

(4) I-frame parsing

The I-frame analysis process is to store the I-frame APDU in the corresponding data structure IEC _ APDU in sequence and analyze the I-frame APDU one by one, and the specific flow is as follows: firstly, analyzing the transmission sequence number of the message in the APCI; then, analyzing a structural body IEC _ ASDU _ TYPE in the IEC _ APDU, storing I-frame ASDU header information in the IEC _ ASDU _ TYPE, and sequentially analyzing the TYPE, the variable structure, the transmission reason and the public information body address; finally, judging the type of the information body through SQ, and respectively reading the addresses of the information body; and analyzing different types of information bodies corresponding to different data structures to obtain specific information contents. Fig. 12 is a diagram of an I-frame parsing process.

IEC104 message repository: the IEC104 message storage library designed by the invention can store the original messages acquired by the message acquisition module in real time and store the analyzed IEC104 messages in a classified manner. Software operators can perform functions of history browsing, searching, deleting, generating column diagrams for comparison and the like on the stored messages. The IEC104 message repository should have both historical and real-time database functions.

The data storage method of the system comprises the following steps: the data of the power department enterprise has the characteristic of high real-time performance, so all real-time data need to be correspondingly changed along with the change of the state of the controlled object. For this real-time data, for example, data of 32-bit floating point type, which requires 1000 points to be collected, the collection frequency is 0.2Hz, the data amount per day is 1000 × 60 × 24 × 4/1024 — 67500K, and the data amount is about 67.5M, and these data are data that continuously increases and changes day after day. While the traditional relational database cannot meet the requirement, the real-time database meets the requirement. Real-time databases are a branch of database system development that is suitable for handling constantly updated and rapidly changing data and in the case of transactions with time constraints.

The basic requirement of the system designed by the invention is to record the data message acquired from the power information system in real time and query and apply the data message at any time. The system can realize the functions of carrying out statistical analysis on the data, forming a data table or a trend curve and the like. For the functional requirement of real-time data recording, the invention adopts a storage method of a real-time database, and simultaneously, in view of the fact that the price of the current domestic popular real-time database product is very expensive, the idea of specially purchasing a set of real-time database products only based on the requirement is too waste. Therefore, the design automatically designs and develops a memory database by researching the design concept and the functional characteristics of the real-time database and combining the specific requirements of the system, and realizes real-time storage and processing of data in the memory by putting all the data into the memory. Meanwhile, a traditional relational database is introduced, data acquired from a memory database in real time are stored through an automatic scheduling system of the system, and finally, the processing processes of statistical analysis and the like of historical data are achieved.

In the conventional relational database, data is stored in a disk by operating disk I/O, and a memory database directly puts the data into a memory, so that the read-write speed is about 5 orders of magnitude higher. Because the data in the memory is volatile, the data stored in the memory will disappear immediately after the system is broken off, and will not be recovered even after power is turned on. Therefore, the system can save the data in time through the relational database, and reduce the data loss of the memory to the maximum extent.

The system only needs to record the description information, the polarity, the raw data, the data value and the quality bit of the data message in real time. Therefore, only one data table needs to be designed to fulfill the function requirement. The information of its database table is shown in table 5.

TABLE 5 database information Table

According to the information in table 5, a database script of SQLServer is created, which is as follows:

CREATE TABLE MESSAGE(

Mid INT PRIMARYKEY,

Desc VCHARNOTNULL,

Polar BIT NOTNULL,

Data BIT NOTNULL,

DataValue BIT NOTNULL,

Quality BIT NOT NULL,

CreateDate DATETIME)；

as described above, the table design for the database is performed, and the table structures of the database tables of the in-memory database and the relational database are consistent.

The data storage of the system is realized as follows: the research and development of the system mainly use C + + programming language, and for the realization method of the memory database, an object-oriented thinking mode is used. According to the mode, firstly, a database table structure is abstracted into an entity type MESSAGE, then a Map container is constructed, KEY of the container is CreateDate in the database table structure, VALUE of the container is an object of the entity type MESSAGE, and according to the principle that the CreateDate of each record is different, the Map container can completely record each piece of data.

For the Data storage operation of the relational database SQL Server, the present design uses ado (activex Data object), which is an API proposed by Microsoft to achieve access to Data in a relational or non-relational database. In the system, each data record in the memory database can be successfully and completely stored by establishing the one-to-one corresponding relation between the entity type MESSAGE and the relational database data table and utilizing the related API of the ADO. The operation process is mainly divided into 4 steps: adding support for ADO, creating a data source connection, operating on a database in the data source, and closing the data source.

By the method, a large amount of data in the system can be successfully stored in real time, and for other applications (such as statistical analysis) of the data, the relevant data can be directly obtained from the database, and various forms of statistical analysis and other operations can be realized through programming.

IEC104 message simulation sending module: the message sending is used as the main function of the scheduling master station, and the working process is as follows: after the network connection is established between the scheduling master station and the telemechanical substation, the scheduling master station sends a link starting command in a U format to the slave station, then the master station sends a total calling command to the slave station, initiates total calling to the remote measurement and remote signaling of the slave station, and meanwhile the master station can also realize time setting of the master station and the slave station through issuing the time setting command and send the remote control command and the remote adjusting command to the slave station. The IEC104 message simulation sending function designed in the simulation IEC104 master station can send the messages to the master station, and a series of corresponding functions are realized.

Sending a U frame starting command: and when the TCP connection is successful, the man-machine friendly interface displays the TCP connection and pops up a TCP connection success dialog box. At this time, the software operator can click and send the U frame start command through the interface. The IEC104 analog messaging module generates a startup U frame with the first bit control field set to 0x 07. And message transmission between the master station and the substation is started, and an operator can judge whether the starting is successful according to whether a starting command confirmation frame of the substation is received or not. The specific process is shown in fig. 13.

Sending a total calling command: after the starting command sent by the IEC104 master station is simulated successfully, the human-computer interaction interface pops up a corresponding message analysis module to remind the user of successful starting, and at the moment, an operator can generate a total calling command message through the simulated message sending module to send the message until the substation receives the total calling confirmation naming sent by the substation. The type identifier and the transmission reason of the generated total recall command I frame message are set to 0x64 and 0x07, respectively. And the master station to be simulated receives a confirmation message of the total calling command of the telemechanical. The I frame recall command is shown in fig. 14.

Sending a remote control and remote regulation command: the analog message sending module can generate remote control and remote regulation commands of different ASDU types. Software users can send various remote control and remote measurement commands to the telecontrol machine through a man-machine interaction interface simulating the IEC104 main station.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the present invention, and therefore, the scope of the present invention should be determined by the scope of the claims.
