[0029] The technical solutions of the application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the application, rather than all the embodiments of the application.

[0030] Embodiment one:

[0031] As shown in the figure, the batch remote operation and maintenance and data checking method of the electric meter terminal in the distribution transformer station house comprises the following steps: Figure 1

[0032] Step 1, initialization to establish three working threads:

[0033] 1.1, creating a communication protocol stack management thread for managing the scheduling operation of the communication protocol stack;

[0034] 1.2, creating a dynamic topology graph thread of the electric meter terminal in the distribution transformer station house for completing drawing, display and data processing of the topology graph;

[0035] ​1.3, creating batch meter terminal operation and data checking operation thread, used to complete the creation and management of thread pool.

[0036] Step 2, three working threads are started in sequence and run in parallel to complete batch remote operation and data checking of meter terminals. The specific steps are as follows:

[0037] 2.1, communication protocol stack management thread:

[0038] 2.1.1, load communication protocol, go to step 2.1.1-1 and 2.1.1-2 respectively;

[0039] 2.1.1-1, perform protocol list matching, start the matched communication protocol, call the communication interface driver function recvfrom to obtain meter terminal communication data, and perform data receiving frame processing and data sending frame processing on the meter terminal communication data;

[0040] 2.1.1-2, parameter configuration, read the topology parameter file in the meter terminal dynamic topology graph thread in the distribution station room when performing parameter configuration; each different communication protocol needs to configure different communication parameters, and the communication parameters of the communication object (meter terminal) are in the topology parameter file, so the topology parameter file needs to be read.

[0041] The meter terminals in the distribution station room are connected to the communication network, and the communication protocol stack management thread completes the collection of meter terminal communication data by calling the communication interface driver function recvfrom of the communication network. The standard protocol stack used for communication with meter terminals currently includes IEC104, IEC103, IEC101, Modbus, DLT645, etc. The communication protocol stack management thread loads these communication protocols into the communication protocol stack, and when communicating with the meter terminal, it automatically matches the corresponding communication protocol to perform data exchange.

[0042] The flow of the communication protocol stack management thread is shown in Figure 2 , and the specific steps include:

[0043] The communication protocol is generated in the form of a dynamic library, and each communication protocol has a globally uniformly defined ID, type, name, parameter, data frame format, framing and deframing interface, and binary tree of data transmission control session. These elements constitute the basic components of a communication protocol.

[0044] Protocol stack establishment. The protocol stack establishment function is called to establish the communication protocol stack, which uses a tree-shaped map data structure, with the key value being the protocol global ID and the Value value being a struct data structure containing the name, parameters and data frame format of the communication protocol. The communication protocol stack is a global variable and can be accessed completely. The establishment of the communication protocol stack is carried out in the initialization stage and is resident in memory after establishment, for calling by other modules.

[0045] Protocol automatic matching. When communicating with the electric meter terminal, for unknown communication protocols, first, try to communicate with the electric meter terminal to obtain the communication data frame format; then, call the matching communication function to poll each protocol in the communication protocol stack, compare the communication data frame format with the data frame format of each communication protocol, until a completely matched communication protocol is found, record the type of the electric meter terminal, and then perform real-time data communication; if automatic matching is not successful, switch to manual matching; if manual matching is also not successful, it means that the protocols in the communication protocol stack are incomplete, prompting is needed, and secondary development is needed to be expanded.

[0046] Data receiving frame processing steps: 1) call the communication interface driver function recvfrom to receive the electric meter terminal communication data; 2) discriminate the obtained electric meter terminal communication data, keep it if it conforms to the communication protocol format, otherwise discard it; 3) for the electric meter terminal communication data that conforms to the protocol format, perform data interpretation processing according to the format requirements of the communication protocol; 4) the interpreted data is the real-time data of the electric meter terminal, which is put into the received data storage area for calling by other modules; 5) when fitting the real-time topology graph data in the dynamic topology graph thread of the electric meter terminal in the distribution station house, obtain the real-time data of the electric meter terminal after frame from the received data storage area.

[0047] Data sending frame processing steps: 1) obtain the operation and maintenance / command; 2) convert the operation and maintenance / command into a data format message specified by the communication protocol and store it in the sending data storage area, which is provided with a list cache queue for storing the data format message to be sent; 3) call the communication interface driver function sendto to send data to the electric meter terminal, and the data format message sent comes from the list cache queue of the sending data storage area.

[0048] First, perform data receiving frame processing, and then perform data sending frame processing. The data sending frame processing mainly checks whether there are batch operation and maintenance commands and data calibration commands issued by the batch electric meter terminal operation and maintenance and data calibration operation thread, or operation and maintenance commands issued by the dynamic topology graph thread of the electric meter terminal in the distribution station house, and if so, sends data to the electric meter terminal, and if not, returns to continue checking.

[0049] Is the data expired? If not and there is data, execute the data receiving frame processing step; if expired and there is no data, execute the protocol automatic matching.

[0050] 2.2, the electric meter terminal dynamic topology graph thread in the distribution station building:

[0051] The electric meter terminal dynamic topology graph thread in the distribution station building includes topology graph drawing (using a graph model drawing technique), real-time topology graph data fitting (using a dynamic data / operation and maintenance report fitting technique), and single electric meter terminal operation and maintenance and data checking processing.

[0052] The graph model drawing technique automatically generates a topology graph and data report that conforms to the field standard through modularized graph elements. The drawing process uses standard graph elements and custom graph elements stored in the model graph library for drawing. The size, color, border, direction, and font of the graph elements have been input in advance into the model graph library.

[0053] The specific steps include:

[0054] Each electric meter terminal graph element / operation and maintenance report has globally uniformly defined ID, type, name, data format, data vector direction, change period time, and minimum / maximum / mutation / step / normal value parameters. These parameter data constitute a basic graph element model unit, and any complex or combined graph element model is composed of basic graph element model units.

[0055] The dynamic data comes from the in-memory database, which labels each data with a data tag. The data tag mainly includes data source id, data destination id, type and quality description, time stamp description, and life cycle time data segments. At the same time, the in-memory database establishes an in-memory operation and maintenance report map data structure. The key of the in-memory operation and maintenance report map data structure is the electric meter terminal graph element ID, and the value is the vector dynamic array. The array content is the operation and maintenance entry information of the electric meter terminal.

[0056] The dynamic data / operation and maintenance report fitting technique mainly uses a multi-channel IO time division multiplexing strategy and a synchronous non-blocking message notification mechanism. After obtaining the dynamic data, a map binary tree structure array of the data destination id is established. The type and quality description of each data point is judged. Invalid data is automatically deleted, and valid data is automatically pushed to the corresponding graph element / operation and maintenance report on the topology graph. The graph element / operation and maintenance report executes data processing according to the pushed data, and dynamically changes the display, direction, color, and format of the graph element / operation and maintenance report and other related information.

[0057] The single meter terminal operation and maintenance and data checking processing only needs to click the button on the meter terminal graph element, according to the ID of the meter terminal graph element, to find the operation and maintenance report map data structure, and to show the vector dynamic data information in the value of the map data structure, to perform the operation and maintenance and data checking operation command issuing.

[0058] The topology graph is automatically generated according to a parameter file; the parameter file defines various parameter data in the topology graph, such as the number, type, position, color, connection point, data association information and meter terminal matching data.

[0059] 2.3, batch meter terminal operation and data checking operation thread, supports maximum 128 meter terminals for parallel operation and data checking operation at the same time. As shown in Figure 3 The specific steps include:

[0060] The thread pool is established by using an independent class, the thread pool in the class uses a list queue structure, each unit in the list queue structure stores a thread data structure, including thread ID, corresponding meter terminal ID, thread start / close function pointer, thread running state and thread calling number, and the initialization list quantity is 128, that is, the maximum thread quantity is 128.

[0061] The thread pool class provides two class variables, syncLock synchronization lock and dataMutux data mutual exclusion. The syncLock synchronization lock ensures the accuracy and synchronization of data during parallel operation and data checking operation, and the dataMutux data mutual exclusion ensures that multiple threads do not conflict and cover when writing memory data.

[0062] After the batch meter terminal operation and data checking operation is completed, the threads are released back to the thread pool in the order of each meter terminal end, to save memory resources and facilitate next use; all batch operation and data checking operation information is recorded into the database, the database table is established according to the operation order id, and the field is longBinary type, used to save all information of the batch operation.

[0063] The main purpose of establishing the thread pool is to perform batch operation and data checking of the meter terminal, and to allocate a thread for each meter terminal for operation and data checking. The advantages of this are: 1) multiple meter terminals can be operated at the same time; 2) data does not fight, and there is no conflict, and the data is completely accurate.

[0064] In the dynamic topology graph thread of the electric meter terminal in the distribution transformer station house, it is the operation and maintenance and data checking operation interface of a single electric meter terminal, because the user sometimes performs operation and maintenance and data checking operation on a certain electric meter terminal on the topology graph; in the batch electric meter terminal operation and maintenance and data checking operation thread, operation and maintenance and data checking operation is performed on multiple electric meter terminals simultaneously in an interface. The operation and maintenance and data checking command issuing and display of the two operation modes are the same, and the purpose of providing two operation and display interfaces is to prevent user misoperation.

[0065] Embodiment two

[0066] As shown in Figure 4 , the embodiment two of the present application provides a batch remote operation and maintenance and data checking system of electric meter terminals in a distribution transformer station house based on a domestic self-controllable operating system, which is used to realize the batch remote operation and maintenance and data checking method of electric meter terminals in a distribution transformer station house as described in embodiment one.
