[0023] The technical solution in the embodiment of the present application is to solve the problem that the current engine oil pressure monitoring alarm is single and has low functionality. The overall idea is as follows:

[0024] Example:

[0025] See also Figure 1 A multi-level engine oil pressure alarm device includes an electrically connected engine test software host computer 2 and an engine 1. The engine test software host computer 2 is configured to collect oil pressure, speed, and torque data from the engine 1 and issue multi-level alarm signals to indirectly control its operating status. The engine test software host computer 2 is capable of performing calculations and comparisons on the engine oil pressure, engine speed, and engine torque data collected from the engine 1, and generating engine alarm signals of varying severity.

[0026] In this embodiment, the engine test software host computer 2 can pre-set alarm parameters. The pre-set alarm parameters can serve as a reference for the collected data, i.e., a comparison value, so that an alarm signal can be issued when there is a discrepancy between the collected data and the comparison value range.

[0027] In this embodiment, after collecting data, the engine test software host computer 2 performs engine alarm calculations and compares the calculation results with pre-set alarm parameters to generate a multi-level alarm signal. The multi-level alarm signal includes a first-level engine sound and light alarm, a second-level engine sound and light and idle alarm, and a third-level engine sound and light and shutdown alarm. After data comparison, the multi-level alarm signal can provide different levels of alarm prompts based on the range of values exceeded by the data, allowing for more precise control of the operating status of the engine 1 and significantly improving the engine oil pressure alarm function.

[0028] In the present embodiment, the engine level one sound and light alarm only sends a sound and light signal to remind the staff. Wherein, the engine level one sound and light alarm belongs to a mild alarm signal, which is used to remind the staff to pay attention to the situation of the lower engine 1.

[0029] In this embodiment, an engine controller 3 is further included, which is connected to the engine 1 and the engine test software host computer 2. The engine's secondary sound and light alarm and idle speed alarm simultaneously trigger an engine idle speed command. The engine idle speed command transmits command information to the engine controller 3, which then drives the engine 1 to operate in an idle state. The secondary sound and light alarm and idle speed alarm are more serious than the primary sound and light alarm. When the secondary sound and light alarm and idle speed alarm occur, the alarm signal and the engine idle speed command are synchronously transmitted to the engine controller 3 to control the engine 1 to switch to an idle state, thereby enhancing the alarm function for excessive oil pressure.

[0030] In this embodiment, the three-stage audible, visual, and shutdown alarm triggers an engine shutdown command, which transmits command information to the engine controller 3, which then drives the engine 1 into a shutdown state. The three-stage audible, visual, and shutdown alarm is the most serious alarm signal. When the three-stage audible, visual, and shutdown alarm occurs, the alarm signal and the engine shutdown command are synchronously transmitted to the engine controller 3 to control the engine 1 to switch to a shutdown state, further enhancing the alarm function for excessive oil pressure.

[0031] In this embodiment, the engine test software host computer 2 and the engine 1 specifically use CAN bus communication, which has high stability.

[0032] In this embodiment, a power input control module 4 is further included. The engine test software host computer 2 sends power parameters to the power input control module 4, and the power input control module 4 is used to input a corresponding voltage or current to the engine 1 based on the generated power parameters. The power input control module 4 can receive the control of the engine test software host computer 2 to transmit voltage or current to the engine 1, ensuring that the engine 1 is in a normal voltage and current state.

[0033] In this embodiment, the power input control module 4 communicates with the engine test software host computer 2 via a serial communication protocol.

[0034] When the engine oil pressure is tested and the alarm is triggered:

[0035] The engine test software host computer 2 collects engine oil pressure, engine speed and engine torque from the engine 1, and generates an engine alarm through the collected data. The engine alarm calculation is compared with the set alarm parameters to generate an engine first-level sound and light alarm, an engine second-level sound and light and idle alarm, and an engine third-level sound and light and shutdown alarm. Here, the engine first-level sound and light alarm only sends out a sound and light alarm to remind the operator; the engine second-level sound and light and idle alarm sends out a sound and light alarm and triggers the engine idle command at the same time. The engine idle command sends the command information to the engine controller 3, and the engine controller 3 drives the engine 1 to run in the idle state; the engine third-level sound and light and shutdown alarm triggers the engine shutdown command, and the engine shutdown command sends the command information to the engine controller 3, and the engine controller 3 drives the engine 1 to run in the shutdown state. In this way, different degrees of alarms can be made for different oil pressure values, and more functions are provided.

[0036] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
