2. And issuing the collection task, and collecting the electric power data by the network shutdown machine according to the collection task.
In this embodiment, taking a subtask 1 in the collection task 1 as an example, a detailed description is given to a process of issuing the collection task, where an implementation flow is shown in fig. 3, and the process is as follows:
step 1: the debugging workstation monitoring service issues an acquisition task command through a command pipeline, wherein the acquisition task command comprises an acquisition task 1, an acquisition subtask 1, a task downloading operation type, an acquisition time length and a main station channel empty, and an access channel of a spacer layer device is an AA1 channel; the command pipeline interaction protocol adopts a TCP communication protocol, the debugging workstation is a TCP communication client of the command pipeline, and the gateway machine is a TCP communication server of the command pipeline. The frame format of the acquisition subtask command comprises an acquisition task sequence number, an acquisition subtask sequence number, an operation type, acquisition task duration, a main station channel number and a spacer layer device sequence number. When the values of the main station channel number and the sequence number of the spacer layer device are nonzero, the acquisition of the power data of the type and the channel number is indicated, at least one of the two channel types is nonzero, and namely one type of channel number needs to be selected.
Step 2: after the network shutdown machine receives a downloading command of an acquisition task of a debugging workstation, data in a command pipeline is analyzed, and communication parameters of a main station channel or a spacer layer device, such as a main station IP address group and a port number, a spacer layer device IP address group and a port number, are acquired from a local database or file of the network shutdown machine according to a channel number. Typically, the master IP address set contains a plurality of IP addresses and the spacer device IP address set contains a/B network IP addresses. For example, the gateway machine a receives the collection task 1, and analyzes the associated parameters of the AA1 channel (for example, the gateway machine a has an internet IP of 10.100.100.3, the bay level device 1 has an internet IP of 10.100.100.36, the in-station access rule is IEC61850, and the port number is 102); starting an acquisition process, starting to acquire power data, and returning a task state response frame of 'acquiring' to the debugging workstation.
And step 3: the debugging workstation receives the task state response frame of 'collecting', and then sets the collecting state of the monitoring service for subsequent selection and issuing of the task of 'stopping collecting'.
And 4, step 4: the debugging workstation periodically inquires the state of the collection task: the query parameters are acquisition task 1 and acquisition subtask 1, namely the acquisition task corresponding to the AA1 channel.
And 5: the network shutdown device responds to the command for inquiring the state of the collection task by the collection task state information frame, and the debugging workstation sets the state of the collection task according to the information content of the task state response frame.
Step 6: and after the network shutdown machine acquisition task reaches a specified time, ending the acquisition process, and returning a state response frame of 'acquisition end' to the debugging workstation, wherein the state response frame comprises an acquisition task 1 and a subtask 1, an 'acquiring' state, a data packet size and a data packet file name, and the data packet file name is 01_01_201907152329. msg.
And 7: the monitoring service of the debugging workstation sets the state of the ending of the acquisition task according to the state information frame, and then the process of acquiring the power data through the data pipeline can be selected.
3. And acquiring the power data acquired by the network shutdown machine.
When the network shutdown machine completes the collection task, the collected power data is sent to the debugging workstation, and the implementation flow is as shown in fig. 5, and the specific steps are as follows.
Step 1: the commissioning workstation monitoring service checks that the acquisition subtask 1 is in the acquisition complete state.
Step 2: the debugging workstation monitors the data transmission service of the service connection gateway machine, and establishes a data pipeline; and issuing a power data request frame message, wherein the power data request frame message comprises a collection task number, a collection subtask number, a file name of the power data and a file size. The data pipeline protocol adopts a TCP communication protocol, the debugging workstation is a TCP communication client, and the gateway machine is a TCP communication server.
And step 3: the network shutdown data transmission service prepares and checks the power data (01_01_201907152329.msg) according to the data request frame parameters, and returns a data request confirmation frame (comprising a file name and a size) to the debugging workstation.
And 4, step 4: after the monitoring service of the debugging workstation receives the data request confirmation frame, the receiving state of the power data file is set, and the size of the receiving file is set at the same time, so that whether the file is successfully received or not is judged in the follow-up process.
And 5: the embedded equipment collects the file data content of the task service and starts to transmit the power data to the debugging workstation, and meanwhile, a subsequent bit is set to be 1, namely, a file data frame is further arranged subsequently.
Step 6: when the file data is transmitted to the last frame, the 'subsequent bit is set to 0', namely 'the file data transmission is finished and no file data frame follows'.
And 7: the debugging workstation monitors the service to complete the reception of the file data of the last frame, checks whether the file data is correct, and generates a data packet file (01_01_201907152329.msg) in the debugging workstation, as shown in fig. 6; and meanwhile, setting a receiving end state of the data packet file. After the debugging workstation receives the collected data of each subtask, whether the problem occurs in the power data transmission process can be judged according to the received data. And the subsequent monitoring service calls an analysis function to display and analyze the power data acquired by the task.
In order to improve the flexibility of acquisition, the invention can also stop acquisition at any time, namely the debugging workstation can issue an acquisition stop command to the network shutdown machine at any time, the specific implementation process is shown in fig. 4, and the steps are as follows:
step 1: the debugging workstation monitor service checks the task state currently being collected.
Step 2: the monitoring service of the debugging workstation selects a command of stopping the acquisition task, and the command parameters are an acquisition task serial number and a subtask serial number.
And step 3: the remote acquisition service of the network shutdown machine selects the subtasks needing to be stopped from acquisition according to the order of the debugging workstation, and stops the acquisition process of the acquired subtasks; and returns a collection task state response frame of collection task suspension to the debugging workstation.
And 4, step 4: and the monitoring service of the debugging workstation sets the state of the ending of the acquisition task according to the state information frame.
Through the process, the power data can be acquired according to the needs, the problem that the real-time local acquisition and remote transmission of the power data of the substation network shutdown machine without a keyboard and a display interface is solved, and the problem that the substation network shutdown machine cannot acquire the power service data according to the service requirements at the same time is also solved.
