With the continuous progress of technology, as an important part of energy supply, the management and monitoring of the operating state data of generator sets have become increasingly important. Traditional monitoring methods have problems such as untimely information transmission and unintuitive data display. To solve these problems, the present invention proposes a method for managing the operating state data of a generator set based on an LED screen display. By setting a control cabinet PLC and an LED screen in the generator set LCU and establishing a network link, real-time monitoring and intuitive display of the operating state data of the generator set are achieved, providing a more convenient and effective monitoring means for operation and maintenance personnel.

[0003] Currently, there are some defects in the existing technical solutions, such as unstable information transmission and unintuitive data display.

The data display method is usually relatively simple, lacking intuitiveness and interactivity, which is not conducive to operation and maintenance personnel making timely and accurate judgments and processing of the operating state of the generator set. The present invention uses an LED screen display and combines it with a flexible LED screen programming software for custom configuration, making the data display more intuitive and clear, and having a certain degree of interactivity, which can be flexibly adjusted according to actual needs, thus solving the problem of unintuitive data display existing in the existing technical solutions.

In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through simulation experiments.

[0084] Build the control cabinet PLC and the LED screen in the simulated generator set LCU, and connect to the aggregation switch. Simulate the generation of generator operating condition data through a simulated collector, including the active power and speed of the No. 1 generator set, and the corresponding data of the No. 2 generator set. Assume that the active power of the No. 1 generator set is 1000 kW and the speed is 1500 rpm, and the active power of the No. 2 generator set is 1200 kW and the speed is 1600 rpm.

[0085] Associate the display screen of the LED screen with simulation data variables. According to different numerical values of the data, the LED screen displays corresponding colors or texts. For example, when the active power of Generator Set No. 1 is 1000 kW, the LED screen displays green, indicating that the unit is in normal power generation state; when the rotational speed of Generator Set No. 2 is 1600 rpm, the LED screen displays yellow, indicating that the unit is in no-load state. The specific data of the active power and rotational speed of the two generator sets are shown in Table 2 below:

[0087] Generator set Active power (kW) No. 1 1000 No. 2 1200 Generator set Active power (kW)

[0088] Among them, in addition to the active power and rotational speed data, the status of the generator sets is added. For example, the active power of Generator Set No. 1 is 1000 kW, the rotational speed is 1500 rpm, and the status is normal power generation; the active power of Generator Set No. 2 is 1200 kW, the rotational speed is 1600 rpm, and the status is no-load.
