Detailed Description
The invention will be further described with reference to the drawings.
The invention provides a four-remote signal parameter checking method, which is characterized in that a virtual master station system is established according to a real regulation master station, and a series of parameter checking with a substation is completed through the butt joint of the virtual master station and the substation, and the method mainly comprises the following steps:
firstly, establishing a virtual master station, namely firstly, constructing a set of relatively complete virtual master station system, wherein the virtual master station can adopt a mobile PC with higher configuration, and oracle VM VirtualBox virtual machine software is installed on the PC. And then installing an operating system and a database which are the same as the real regulation system in the virtual machine, and deploying data receiving and processing functions which are completely consistent with the real regulation system, wherein the PC can be completely used as a mobile master station independently. And then, a CIM-E format model file and a G format graphic file are derived from a real regulation master station, the files are packaged and then uploaded to a virtual master station system in an SFTP mode and the like, the virtual master station with the image model imported is carried to a substation for signal acceptance in a butt joint manner with the substation, and the virtual master station can directly interact data with the substation and can directly operate a field switch or a measurement and control device. And then, checking whether the signals sent to the virtual master station by the substation are consistent with the signals received by the virtual master station, and if not, adjusting and maintaining the model and the graph in the virtual master station until the data received by the virtual master station are completely consistent with the data sent by the substation. At this time, the single-factory-station model export function of the dispatching master station can be used for exporting CIM-E format model files and G format graphic files and packaging the CIM-E format model files and the G format graphic files into version files (models or graphics which are finally checked and accepted by the virtual master station are imported into an actual master station system, interaction is carried out through the single-factory-station model import function, a data backup file is generated after each interaction, the data backup file is called as a version file and can be used for operations such as data rollback), the data backup file can be returned to the master station system through SFTP and the like, and the master station system can form addition, deletion and modification records through the single-factory-station model import function after analysis, verification and comparison, update the model difference records into the master station system model library and generate pattern-model association by the mapping model library.
Step two, checking static parameters of the acceptance point table automatically
The virtual master station system reads an acceptance information point table of an OMS (power dispatching management system) through a built-in parameter checking module, compares the read information point table with a database in the virtual master station, compares whether remote measurement, remote signaling and remote control point numbers (the remote control point numbers and the remote control point numbers are combined together) in the acceptance information point table exist in the virtual master station or not, whether the names are consistent or not, gives a prompt if the point numbers do not exist or the names are inconsistent, and records a checking result; checking whether the remote signaling alarm level in the information point table is consistent with that in the virtual master station, if not, giving a prompt, and recording a checking result; and checking whether the protection signal is set as an optical character plate in the virtual master station database or not according to the protection signal, if not, giving a prompt, and recording a checking result.
Step three, automatic point-to-point of remote signaling
The virtual master station issues a remote signaling starting point-to-point command according to the remote signaling acceptance information point table, the substation automatically triggers remote signaling signals to be sent up according to the sequence of the remote signaling information point table and a target value after receiving the command, and the virtual master station automatically compares the remote signaling signals with the sequence and the target value set in the remote signaling acceptance information point table after receiving the remote signaling signals of the substation, and gives an alarm when the remote signaling signals are inconsistent. The automatic point-to-point process of remote signaling is specifically as follows:
firstly, starting a remote signaling automatic point-to-point command of a virtual main station, resetting all remote signaling in a master control to a separate (reset) state after a substation receives the command, and then starting remote signaling information of a substation signal triggering module to be sent upwards; the automatic checking and accepting module of the virtual main station receives the change remote signaling in real time, checks the remote signaling state, checks the sequence consistency of the point numbers and the checking and accepting point list, records the checking result, and gives out prompt and remark error reasons when the results are inconsistent, as shown in figure 1.
Step four, telemetering automatic point-to-point
The virtual master station issues a telemetry start point command according to the telemetry acceptance information point table, the substation automatically triggers telemetry data to be sent up according to the sequence of the telemetry acceptance information point table and a target value after receiving the command, the virtual master station automatically compares the telemetry data with the sequence and the target value set in the telemetry acceptance information point table after receiving the substation data, and carries out alarm prompt when the data are inconsistent, and the telemetry automatic point-to-point specific flow is as follows:
firstly, starting a remote-measuring automatic point-to-point command of a virtual master station, resetting all remote-measuring amounts in a master control to 0 after a substation receives the command, and then starting remote-measuring data of an automatic signal triggering module of the substation to upload; the virtual master station automatic acceptance module receives the change data in real time, compares the change data with an acceptance point table, records deviation between a telemetry value and a set value, and gives a prompt and remark error reasons when comparison results are inconsistent. The telemetry automatic point-to-point flow is shown in figure 2.
Step five, remote control (remote adjustment) automatic acceptance
The remote control automatic acceptance is initiated by the virtual master station, and the remote control acceptance information point table is used as the basis to control the operation one by one. The remote control automatic acceptance process is as follows:
firstly, inputting a user and a password in a virtual master station to verify the remote control authority of the user, inputting a station name to verify whether the remote control station is correct, and selecting a responsibility area to verify whether the responsibility area meets the requirement; and then, according to a remote control point list listed by the factory station, a remote control sequence is checked and generated in a mode of single selection, multiple selection, sequential selection and the like, and is used as an actual control sequence for automatically checking and accepting the remote control signal. After the virtual master station starts a start command, the remote control operation is sequentially executed in a single step or continuously according to the control sequence, the next operation can be continuously executed after the single execution is finished as required for the single step execution mode (the single remote control means one remote control cycle of switching on and switching off), a remote control failure prompt is given for remote control failure, the remote control failure prompt is automatically marked, and the switch marked with the remote control failure automatically generates a remote control operation sequence again. The remote control interaction flow is shown in fig. 3.
The embodiments are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited by the embodiments, and any modification made on the basis of the technical scheme according to the technical idea of the present invention falls within the protection scope of the present invention.
