Description

Technical Field

[0001] The present application relates to the field of data processing technology, and in particular to a method and system for automatically counting the operating frequency and duration of an air compressor. Background Art

[0002] Compressed air is an excellent medium for storing energy. Due to its ease of use and storage, it is widely used in power plants. Power plants often have air compression systems for oil pressure devices, brake air, and industrial air. These systems supply air to the oil pressure devices and cylinder valves in the speed control systems of the generator sets, as well as to the brakes and main shaft maintenance seals of the entire plant's units. They also supply air for pneumatic tools, purging, and desilting during unit installation and maintenance. The proper functioning of the air compression system directly impacts the operating condition of the generator sets.

[0003] The air compression system mainly consists of an air compressor (hereinafter referred to as air compressor), an air storage tank, an air purification device, an air supply network, and measurement and control components. By analyzing the number of times the air compressor operates within a certain period (i.e., the operating frequency) and the duration of a single operation, the operating condition of the air compression system can be detected. If the air compressor operates abnormally or there are defects such as leaks in the air storage tank or air supply network, they can be discovered and handled in a timely manner.

[0004] Existing remote monitoring systems and PLC controllers can control the start and stop functions of air compressors, but they only record operating status signals and lack dedicated statistical modules for the frequency and duration of air compressor operations. These statistics cannot be automatically collected, requiring manual analysis, which is time-consuming and labor-intensive, and carries the risk of human error. The frequency and duration of air compressor operations cannot be automatically compared with data from previous periods (such as the previous day or hour), making it difficult to detect defects in the air compression system equipment. Summary of the Invention

[0005] In view of this, the present application provides a method and system for automatically counting the operating frequency and duration of an air compressor.

[0006] The present application discloses a method for automatically counting the operating frequency and duration of an air compressor, which comprises: Step 1: The data acquisition unit collects the operating current and frequency of the air compressor in real time and inputs the data into the data processing unit; Step 2: The data processing unit processes the received data; Step 3: The data output by the data processing unit is stored in the data storage unit, and the data can be called by the user terminal at any time; Step 4: Query the air compressor operating frequency and operating time in the user terminal as needed, or output a visual chart. If the relevant data is obviously abnormal or the mobile user terminal receives an alarm message, go to the site to check the operation of the air compression system, and promptly discover and deal with defects; the relevant data includes operating frequency and operating time.

[0007] Furthermore, the step 2 includes: Step 21: The data processing unit compares the collected air compressor operating current I and frequency f with preset values; Step 22: If the data processing unit determines that the air compressor is running, the air compressor start timestamp and the air compressor stop timestamp are recorded, and the air compressor single running time T is calculated, T = air compressor stop timestamp - air compressor start timestamp, and the air compressor running times n is increased by 1; Step 23: Determine whether to issue an air compressor alarm signal based on the number of air compressor operation times and a single operation time; Step 24: Output relevant data to the data storage unit; the relevant data includes the air compressor operating status, single operation time T, operation number n, operation frequency F, air compressor frequent start alarm signal, and air compressor excessive operation time alarm signal.

[0008] Furthermore, the step 21 includes: When the air compressor operating current I ≥ 10% In or the frequency f ≥ 5Hz, the air compressor is determined to be running. When the air compressor operating current I < 10% In and the frequency f < 5Hz, the air compressor is determined to be stopped. Among them, In is the rated current of the air compressor, 10% In and 5Hz are preset values, and the preset values ​​are adjusted according to actual conditions.

[0009] Furthermore, the step 23 includes: Accumulate the number of air compressor operations and compare the air compressor operation frequency F with the operation frequency threshold △F. If F>△F, an air compressor frequent start alarm signal is issued; Compare the single running time T of the air compressor with the running time threshold △T. If T>△T, an alarm signal of excessive running time of the air compressor is issued.

[0010] Furthermore, the number of times the air compressor operates within a specified period, that is, the operating frequency F, is calculated; the specified period includes one hour, one day, one week, and one month.

[0011] The present application also discloses a system for automatically counting the operating frequency and duration of an air compressor, which implements the above-mentioned method for automatically counting the operating frequency and duration of an air compressor. The system consists of a data acquisition unit, a data processing unit, a data storage unit and a user terminal.

[0012] Furthermore, the user terminal includes a PC management platform and a mobile user terminal. The user terminal has query function, output function and push function, which is used to query the air compressor operation frequency and single operation time within a time period, and output visual charts. The visual charts include air compressor operation frequency statistics table, single operation time statistics table, historical data line chart, daily report, weekly report and monthly report.

[0013] Furthermore, when the operating frequency or operating time of the air compressor exceeds a preset alarm value, the PC management platform is used to push an alarm message to the mobile user terminal.

[0014] Due to the adoption of the above technical solution, this application has the following advantages: 1. Real-time identification of the operating status of the air compressor, automatic statistics of the operating frequency and duration of the air compressor, reducing labor costs, improving work efficiency, and reducing the risk of human error.

[0015] 2. The alarm thresholds for the air compressor operation frequency and single operation duration can be set according to actual conditions so that the alarm signal can be reported in time.

[0016] 3. The user terminal can output visual charts such as the air compressor operation frequency statistics table, single operation duration statistics table, historical data line chart, etc. Combined with historical data, the correlation between the air compressor operation frequency and duration and the gas demand of the generator set can be analyzed to optimize the air compressor scheduling strategy.
