It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein.

[0042] This utility model provides a locomotive display device. Figure 1 This is a structural schematic diagram of a locomotive display device according to an embodiment of the present utility model, with reference to... Figure 1 The locomotive display device includes:
[0043] Display screen 1, data processing module 2, and communication module 3;
[0044] The first end of the communication module 3 is connected to the fault prediction and health management system 4, and the second end of the communication module 3 is connected to the first end of the data processing module 2. The communication module 3 is used to receive the air compressor detection signal transmitted by the fault prediction and health management system 4 and transmit the air compressor detection signal to the data processing module 2.
[0045] The second end of the data processing module 2 is connected to the display screen 1. The data processing module 2 is used to receive the air compressor detection signal, compare the air compressor detection signal with the internally set threshold detection signal, generate a detection data display signal based on the comparison result, and transmit the detection data display signal to the display screen 1 for display.
[0046] Specifically, this invention addresses the issue of older locomotives where the air compressor detection information obtained by the Prognostics and Health Management (PHM) system cannot be displayed on a panel. A novel locomotive display device is designed for these older locomotives. The PHM system 4 acquires various detection information from the air compressor in real time and converts this information into air compressor detection signals, which are then transmitted to the data processing module 2. For example, the various detection information includes lubricating oil temperature, internal pressure, intake pressure, exhaust pressure, and exhaust temperature. Upon receiving the air compressor detection signals, the data processing module 2 compares them with internally set threshold detection signals and generates a detection data display signal based on the comparison result. This signal is then transmitted to the display screen 1 for display. For example, if the intake pressure signal in the air compressor detection signal is greater than the intake pressure threshold detection signal, it can be determined that the air compressor's intake pressure is abnormal. If other detection signals in the air compressor detection signal are not abnormal, the display screen 1 can differentiate between the abnormal and normal detection signals based on the generated detection data display signal. Figure 2 This is a schematic diagram of the interface display of a locomotive display device according to an embodiment of the present utility model, with reference to... Figure 2 The locomotive display device can display real-time information on lubricating oil temperature, internal pressure, intake pressure, exhaust pressure, and exhaust temperature, and distinguish between abnormal detection information and non-abnormal detection information.
[0047] The locomotive display device provided in this embodiment includes a display screen 1, a data processing module 2, and a communication module 3. The communication module 3 receives the air compressor detection signal transmitted by the fault prediction and health management system 4 and transmits the air compressor detection signal to the data processing module 2. The data processing module 2 receives the air compressor detection signal and compares it with an internally set threshold detection signal. Based on the comparison result, it generates a detection data display signal and transmits the detection data display signal to the display screen 1 for display. This solves the problem that old locomotives cannot display the air compressor detection information obtained by the fault prediction and health management system on the panel. It allows staff to judge the working status of the air compressor on-site without relying on other equipment, achieving accurate assessment of the air compressor's health status. Compared with the prior art, which requires staff to download the air compressor detection information in real time, this reduces the workload of staff, shortens the fault identification time, and thus reduces the maintenance cost of a single locomotive.
