Description

A time synchronization monitoring method and system for power collection terminal

Technical Field

The present invention relates to the field of data processing technology, and more specifically, to a time synchronization monitoring method and system for a power collection terminal.

Background Art

Power collection terminals and time synchronization monitoring are crucial technologies in power systems, which are used to ensure accurate collection and synchronous recording of power data, thereby ensuring reliable operation and efficient management of power systems. Power collection terminals are mainly used to collect various data in power systems in real time, including parameters such as voltage, current, power, and frequency. These data are of great significance for the monitoring, dispatching, analysis, and optimization of power systems. The time synchronization monitoring method is the key technology to ensure that these data have a unified timestamp, ensuring that the data collected by different terminals can be accurately matched and seamlessly connected, thereby providing an accurate basis for the analysis and control of power systems. The current power collection terminal time synchronization monitoring method mainly relies on a variety of time synchronization technologies, including global positioning system, network time protocol, precision time protocol, etc. These technologies can provide high-precision time synchronization services, enabling power collection terminals distributed in a wide area to obtain accurate time information.

The patent document with publication number CN110673464B discloses a time synchronization method and device for a power collection terminal. The time synchronization method for the power collection terminal includes: obtaining the time synchronization type of the power collection terminal; selecting a corresponding target time synchronization operation instruction from multiple time synchronization operation instructions according to the time synchronization type; sending the target time synchronization operation instruction to the power collection terminal so that the power collection terminal performs a time synchronization operation according to the target time synchronization operation instruction. However, although this method solves the time synchronization problem of the power collection terminal to a certain extent, the general time synchronization cycle is fixed, while the equipment working conditions, network environment, etc. faced by the collection terminal are changing. If a fixed time synchronization cycle is adopted, it may be detrimental to the collection effect.

Summary of the invention

In order to solve the problem proposed in the above background technology that the use of a fixed time synchronization period may be detrimental to the acquisition effect, the present invention provides solutions in the following aspects.

In a first aspect, the present invention provides an active time synchronization monitoring method for a power collection terminal, which collects operating power in real time and calculates a time synchronization margin based on the operating power:

;

In the formula, Indicates The timing margin within a time period, Indicated in In the time period The operating power collected each time, Indicated in The maximum value of the operating power collected in a time period, Indicates the number of time periods; if ＜ , then send a synchronization request to the synchronization server; if ≥ , delayed sending; Indicates the timing margin threshold.

Combined with the calculation of the time synchronization margin, more frequent time synchronization operations can be performed during peak operation periods to ensure the real-time and accuracy of data. During off-peak operation periods, the time synchronization cycle can be extended to reduce unnecessary time synchronization operations and save system resources. This intelligent time synchronization cycle management not only improves the time synchronization efficiency of the system, but also optimizes resource utilization and reduces operating costs.

Further, the delayed sending includes: calculating the adjusted time period according to the current time period:

;

in, Indicates the current time period, Indicates the adjusted time period.

The active timing monitoring method can accurately determine the current timing status by collecting and preprocessing operating power data in real time, and calculating the timing margin based on this data. When the timing margin is lower than the threshold, the system will actively send a timing request to ensure the accuracy and timeliness of the timing, thereby improving the timing accuracy of the overall system. By calculating the timing margin and sending the timing request only when necessary, the utilization of system resources is optimized and the system burden is reduced. In particular, by dynamically adjusting the sending cycle strategy, the sending cycle is flexibly adjusted according to the comparison between the timing margin and the threshold, so that the system can flexibly adjust the timing operation frequency according to the real-time timing status and operating power changes, further improving the flexibility and adaptability of the system.

Furthermore, the real-time collection of operating power includes collecting the operating power using a power quality monitor.

Using a power quality monitor to collect operating power in real time can provide accurate power usage data, helping users understand the energy consumption of equipment or systems in real time, and then optimize energy management strategies. By monitoring power fluctuations and changes, users can identify and solve potential energy efficiency problems, improve energy utilization efficiency, reduce energy costs, and help ensure that equipment operates under optimal power quality conditions, extend equipment life, and improve production efficiency and reliability.

Furthermore, it also includes preprocessing the operating power, including: data cleaning, data smoothing and data filtering.

Furthermore, it also includes that the data cleaning adopts the 3σ principle to detect and remove abnormal values of the operating power data, the data smoothing adopts the exponential smoothing method to reduce the short-term fluctuations in the operating power data, and the data filtering adopts the high and low threshold filtering method to filter the operating power data of the power collection terminal.

By preprocessing the operating power, including data cleaning, data smoothing and data filtering, outliers and short-term fluctuations in the data are effectively removed, improving data quality. The timing margin and deviation degree calculated on this basis more accurately reflect the actual operating status of the power collection terminal. The timing cycle is adjusted based on this information, so that the system can adaptively adjust the timing strategy under different operating conditions, enhancing the robustness and adaptability of the system.

Furthermore, the time synchronization request includes two parts: a synchronization request and a time deviation correction parameter, and the power collection terminal performs time correction according to the time deviation parameter.

Synchronization request and time deviation correction parameters. Synchronization request ensures that the power collection terminal is synchronized with the time standard, which helps to ensure the accuracy and precision of data collection. Time deviation correction parameters are used to correct the local time according to the actual situation to ensure that the timestamp of the collected data is accurate. The beneficial effect of this mechanism is that it improves the credibility and real-time nature of the data, helps to accurately analyze power usage, optimize energy management, reduce energy consumption costs, and ensure the stability and efficiency of power system operation.

Furthermore, it also includes that the current time period is an initial time period.

In a second aspect, the present invention provides a passive time synchronization monitoring method for a power collection terminal, comprising: collecting operating power in real time; in response to the distance synchronization moment being equal to a time threshold, calculating a time synchronization margin based on the operating power:

;

In the formula, Indicates The timing margin within a time period, Indicated in In the time period The operating power collected each time, Indicated in The maximum value of the operating power collected in a time period, Indicates the number of time periods; if , the flag is true when the setting is incorrect; if ≤ , set the wrong flag to false; Indicates the timing margin threshold; in response to receiving a timing signal, if the timing mismatch flag is false, respond to the timing signal, otherwise do not respond to the timing signal.

The passive timing monitoring method can accurately judge the current timing status when the distance to the timing moment is equal to the time threshold. When the timing margin is lower than the set threshold, the misalignment flag is set to true, thereby avoiding unnecessary timing operations. This method reduces invalid timing operations, optimizes the utilization of system resources, and reduces the system burden. Secondly, in response to the received timing signal, the system will decide whether to respond to the timing signal based on the status of the misalignment flag. This judgment mechanism based on the timing margin ensures that the system performs timing operations only when it really needs to synchronize, thereby improving the system's timing accuracy and stability. In addition, system failures or performance degradation caused by the accumulation of timing errors are avoided, and the reliability of the overall system is improved. By reducing unnecessary timing operations, the operating efficiency of the equipment is improved.

In a third aspect, the present invention provides a time synchronization monitoring system for a power collection terminal, comprising a memory and a processor, wherein the memory stores computer program instructions, and when the computer program instructions are executed by the processor, the above-mentioned active time synchronization monitoring method for a power collection terminal or a passive time synchronization monitoring method for a power collection terminal is implemented.

The beneficial effects of the present invention are:

In active timing, the timing margin is preprocessed and calculated based on the real-time collected operating power data, and the preset timing margin threshold is used to decide whether to send a timing request, thereby ensuring that the device time is synchronized with the standard time, effectively improving the accuracy and real-time performance of data collection. In passive timing, the timing margin is calculated based on the real-time collected operating power data, and the timing flag is set based on the preset timing margin threshold to decide whether to respond to the timing signal, thereby ensuring data accuracy while improving the automation and efficiency of the system.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Embodiment of the time synchronization monitoring method of the power collection terminal:

As shown in Figure 1, the passive time synchronization monitoring method of the power collection terminal of the present invention is a flow chart. The passive time synchronization scheme is described below:

S101: Real-time collection of operating power. The operating power refers to the power actually consumed or output by the power system or power equipment during operation, usually in watts or kilowatts. A timestamp is usually added when outputting. The timestamp refers to the time information added when recording the operating power data, which is used to identify the specific time point of data collection.

As shown in Figure 3, the data preprocessing structure diagram in the time synchronization monitoring method of the power collection terminal of the present invention includes data cleaning, data smoothing and data filtering. The data cleaning uses the 3σ principle to detect and remove abnormal values from the operating power data, the data smoothing uses the exponential smoothing method to reduce short-term fluctuations in the operating power data, and the data filtering uses the high and low threshold filtering method to filter the operating power data of the power collection terminal.

Specifically, in the power collection terminal, a power quality monitor is installed to monitor the operating power of the power equipment in real time.

S102: Preprocessing the operating power. The preprocessing of the operating power includes: data cleaning, data smoothing and data filtering. The data cleaning uses the 3σ principle to detect and remove abnormal values from the operating power data. The data smoothing uses the exponential smoothing method to reduce short-term fluctuations in the operating power data. The data filtering uses the high and low threshold filtering method to filter the operating power data of the power collection terminal.

The above technical solution can obtain more accurate operating power data through real-time collection and preprocessing, detect abnormal situations in time, and improve the reliability and safety of the power system. Accurate operating power data helps optimize the utilization of power resources and avoid power waste or equipment damage caused by insufficient or overloaded power. The operating power data with timestamps can be used for historical analysis and trend prediction, helping power system operators to formulate more reasonable operation and maintenance plans. By timely detecting and handling abnormal situations, equipment failures and downtime can be reduced, and maintenance and operating costs can be reduced.

S103: In response to the distance synchronization time being equal to the time threshold, calculating the synchronization margin based on the operating power.

The synchronization moment refers to the moment when the system last performed a time synchronization operation. This moment is the accurate time point obtained by the system through synchronization operations, such as synchronization with a synchronization server. The time threshold refers to a pre-set time interval used to control the frequency of synchronization operations. When the time difference between the current time and the last synchronization moment reaches this time interval, the system will trigger a synchronization operation. This threshold is set according to the specific needs of the system to balance the accuracy of time synchronization and the use of system resources. If the current time does not reach the preset time interval, that is, the time difference between the current time and the last synchronization moment does not reach the time threshold, then the current synchronization cycle will not change.

The above technical solution ensures that the system performs time synchronization operations within the set time interval and maintains time synchronization accuracy through preset time thresholds and real-time monitoring. Time threshold control and time synchronization operations combined with operating power data can timely detect and handle abnormal situations and improve system reliability and security. By setting different time thresholds and time synchronization margin thresholds, the system's time synchronization frequency and strategy can be flexibly adjusted to meet the needs of different application scenarios. Calculate the time synchronization margin based on the operating power:

;

like , the flag is true when the setting is incorrect; if ≤ , set the wrong flag to false; Indicates the timing margin threshold.

In response to the distance synchronization moment being equal to the time threshold, in response to receiving a synchronization signal, if the misalignment flag is false, respond to the synchronization signal, otherwise do not respond to the synchronization signal.

Among them, the timing margin is an indicator to measure whether the system needs to perform timing operations. It is calculated based on the collected operating power data and is used to determine the system's time synchronization requirements. The time period represents the time segment into which the system is divided when it is running, and a timing margin is calculated in each time period. The misalignment flag is a logical flag used to indicate whether the system needs to perform timing operations. When the flag is true, the system does not respond to the timing signal; when the flag is false, the system responds to the timing signal. The timing signal is a synchronization time request signal from the timing server, indicating that the system needs to perform time synchronization.

The above technical solution calculates the timing margin based on the operating power data, so that the system can accurately synchronize time when needed. It avoids unnecessary timing operations and ensures that the system's time synchronization is maintained at an accurate level. Dynamically adjust the frequency of timing operations. By setting the wrong timing flag, frequent timing requests can be avoided and the waste of system resources can be reduced. This method optimizes the use of system resources and improves the efficiency of the overall system. Through accurate time synchronization and anomaly detection, equipment failures and downtime are reduced, thereby reducing maintenance and operating costs. Timely timing operations and exception handling can prevent expensive repair costs and production losses caused by equipment failures. Dynamic adjustment of timing operations and timely exception handling help improve the stability and continuity of the system, ensuring that the power system can operate stably and meet the needs of users and production.

;

in, Indicates the current time period, represents the adjusted time period, and the current time period is the initial time period.

= ≈15;
