Example 1
In accordance with an embodiment of the present application, there is provided an embodiment of a data processing method, it should be noted that the steps shown in the flowchart of the figure may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in an order different than here.
Fig. 1 is a schematic flow chart of an alternative data processing method according to an embodiment of the present application, and as shown in fig. 1, the method includes steps S102-S106, where:
step S102, the data monitoring platform receives terminal data transmitted by a plurality of monitoring terminals, wherein the plurality of monitoring terminals complete time synchronization through a GPS, and each terminal data comprises a timestamp marked according to the GPS.
In some optional embodiments of the present application, the data processing method may be applied to a power grid terminal data monitoring scenario, where a plurality of monitoring terminals generally operate in power system substations, such as a power plant, a transformer substation, a distribution box, and the like, and are used to collect terminal data of each power system substation, where the terminal data mainly include power grid waveform data including waveform data information such as voltage and current of the power system substation during operation, and each monitoring terminal may uniformly send the data information to a data monitoring platform; the data monitoring platform is generally operated in a main station of the power system, such as a dispatching center, and is responsible for monitoring terminal data transmitted by each monitoring terminal to confirm the overall operation state of the power grid.
In order to accurately acquire the power grid data of each power system substation at different times and analyze and compare the power grid data at the same time, the time of each monitoring terminal needs to be synchronized first.
The GPS time synchronization technology is a novel technology for timing a computer, a control device, and the like in an automation system, and acquires a standard time signal from a GPS satellite, and transmits the information to devices (such as a computer, a protection device, a fault recorder, an event sequence recording device, a safety automation device, a telemechanical RTU, and the like) requiring time information in the automation system through various types of interfaces, so that time synchronization of the entire system can be realized.
In some optional embodiments of the present application, time synchronization may be performed on each monitoring terminal through a GPS time synchronization technology, so as to ensure uniformity of time; then, when the monitoring terminal transmits the terminal data to the data monitoring platform, the corresponding timestamp can be marked in the terminal data according to the GPS time, so that the terminal data at the same time can be compared subsequently.
And S104, the data monitoring platform retrieves second terminal data from the terminal data transmitted by the second monitoring terminal according to the first terminal data transmitted by the first monitoring terminal, wherein the timestamps of the first terminal data and the second terminal data are the same, the first monitoring terminal is any one of the plurality of monitoring terminals, and the second monitoring terminal is other monitoring terminals except the first monitoring terminal in the plurality of monitoring terminals.
Specifically, after the data monitoring platform receives first terminal data transmitted by a certain monitoring terminal, second terminal data with the same timestamp is retrieved from terminal data transmitted by other monitoring terminals according to the timestamp of the terminal data, and then the first terminal data and the second terminal data are compared.
Although time synchronization is performed on each monitoring terminal through the GPS, it can be ensured that the time for each monitoring terminal to transmit terminal data to the data monitoring platform is the same, however, due to the difference in stability of the transmission channels of each monitoring terminal or the difference in the amount of terminal data transmitted by each monitoring terminal, the time for the data monitoring platform to receive the terminal data transmitted by each monitoring terminal is different, that is, the data monitoring platform cannot simultaneously acquire the terminal data transmitted by all the monitoring terminals.
In view of the foregoing, in some optional embodiments of the present application, the data monitoring platform may first cache the first terminal data, retrieve the terminal data transmitted by the second monitoring terminal and received within a preset time range, determine the second terminal data with the same timestamp as the first terminal data, and then perform a horizontal comparison on the first terminal data and the second terminal data at the same time.
Optionally, when the second terminal data with the same timestamp as the first terminal data is not retrieved from the terminal data transmitted by the second monitoring terminal received within the preset time range, the data monitoring platform deletes the cached first terminal data.
For example, a monitoring terminal corresponding to a first group of terminal data received by a data monitoring platform may be defined as a first monitoring terminal, after the data monitoring platform receives the first terminal data transmitted by the first monitoring terminal, the first terminal data may be cached first, a user may preset a time range according to actual needs, and in the preset time range, whenever there is another monitoring terminal to transmit the terminal data to the data monitoring platform, the data monitoring platform may retrieve the terminal data, determine whether a timestamp of the terminal data is the same as a timestamp of the first terminal data, if so, take the terminal data as second terminal data, and compare the first terminal data with the second terminal data; if the second terminal data with the same timestamp as the first terminal data is not retrieved within the preset time range, the data monitoring platform deletes the cached first terminal data in order to avoid occupying space.
And S106, comparing the first terminal data with the second terminal data by the data monitoring platform, and determining a comparison result.
In some optional embodiments of the present application, when comparing the first terminal data and the second terminal data, in consideration of an influence of a power grid phasor on an operation of an electric power system, the data monitoring platform may analyze voltage and current information in the first terminal data and the second terminal data, determine first power grid phasor information according to the first terminal data, determine second power grid phasor information according to the second terminal data, and then compare the first power grid phasor information with the second power grid phasor information, and when a difference between the first power grid phasor information and the second power grid phasor information is greater than a preset threshold, the data monitoring platform may send an alarm message to inform a user that the power grid operates abnormally.
In the embodiment of the application, the data monitoring platform receives terminal data transmitted by a plurality of monitoring terminals which finish time synchronization through a GPS, and each terminal data comprises a timestamp marked according to the GPS; and then the data monitoring platform retrieves second terminal data with the same time stamp as the first terminal data from the terminal data transmitted by other monitoring terminals according to the time stamp of the first terminal data transmitted by any monitoring terminal, compares the first terminal data with the second terminal data and determines a comparison result. The monitoring terminals are time-synchronized by using the GPS, and the terminal data are stamped with the timestamps, so that the power grid data of different monitoring places at the same time point can be returned and compared, the running states of different positions of the power grid at the same time can be determined, and the technical problem that the power grid data collected by a plurality of power system monitoring terminals are difficult to transversely compare in the related technology is solved.

and the caching module 26 is used for caching the first terminal data.
And a deleting module 28, configured to delete the cached first terminal data when second terminal data with the same timestamp as the first terminal data is not retrieved from the terminal data transmitted by the second monitoring terminal received within the preset time range.
