[0040] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] In an exemplary embodiment, Figure 1 as well as Figure 2 As shown, a water inlet valve oil station startup control method is provided. This embodiment takes the method applied to a terminal as an example for illustration. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0042] Step S100, obtaining a first pressure of the fuel tank;

[0043] Step S200, when the first pressure is the valve opening pressure, opening the isolation valve;

[0044] Step S300, obtaining a second pressure of the fuel tank;

[0045] Step S400, when the second pressure is the pump stop pressure, obtaining the position of the isolation valve;

[0046] Step S500: when the isolation valve is in the open position or the isolation valve is not in the closed position, turn off the oil pump.

[0047] In step S100, during the startup of the water inlet valve oil station, the server first sends a startup command to the terminal, and after receiving the startup command, the terminal starts the oil pump, and the oil pump pressurizes the oil tank so that the pressure of the oil tank gradually increases. At this time, the pressure of the oil tank is obtained and defined as the first pressure.

[0048] In step S200, as the first pressure gradually increases to the valve opening pressure, the isolation valve is opened so that the oil tank is connected to the oil tank. Specifically, the water inlet valve oil station also includes a hydraulic pipeline, and the hydraulic pipeline is connected between the oil tank and the oil tank. The oil tank and the oil tank are connected through the hydraulic pipeline, and the oil in the oil tank is pumped into the hydraulic pipeline by the oil pump and then enters the oil tank. It can be understood that there is a one-way valve between the oil tank and the hydraulic pipeline, and the oil in the oil tank can only be pressurized into the hydraulic pipeline by the oil tank, and cannot flow in the opposite direction. For example, the valve opening pressure can be 3.5MPa.

[0049] In step S300, after the isolation valve is opened, the oil pump continues to work so that the pressure of the oil tank continues to increase. The pressure of the oil tank obtained at this time can be defined as a second pressure.

[0050] In step S400 and step S500, when the second pressure is equal to the pump stop pressure of the oil tank, the position of the isolation valve is obtained. According to the position of the isolation valve, the oil pump is turned off so that the pressure of the oil tank is gradually reduced. Specifically, in this embodiment, when the position of the isolation valve is in the open position or not in the closed position, the oil pump is turned off.

[0051] As an example, after step S500, the following steps are further included:

[0052] Step S600, obtaining a third pressure of the fuel tank;

[0053] Step S700: when the third pressure is the pump starting pressure, start the oil pump.

[0054] After the oil pump is turned off, the pressure in the oil tank gradually decreases. At this time, the pressure of the oil tank is obtained and defined as the third pressure.

[0055] When the third pressure is the pump start pressure, the oil pump is started again, and the oil pump is pressurized, so that the pressure of the oil tank is gradually increased again. When the pressure of the oil tank reaches the preset pressure range, and the isolation valve is in the open position at this time, the oil station is successfully started. The preset pressure range can be 5.8MPa to 6.6MPa.

[0056] In conventional technology, when the oil tank pressure reaches the pump stop pressure, the oil pump can only be shut down when the isolation valve position is detected to be in the open position and the closed position is restored. Therefore, when the isolation valve position is unclear, the oil tank pressure may be pumped to a higher pressure by the oil pump.

[0057] In this embodiment, when the second pressure of the oil tank is obtained as the pump stop pressure, at this time, the isolation valve is in the open position or not in the closed position, and the oil pump can be shut down, thereby avoiding the risk of the oil pump increasing the pressure of the oil tank and the oil tank to too high when the position of the isolation valve is unclear, thereby increasing the reliability of the start-up of the water inlet valve oil station.

[0058] In an exemplary embodiment, the water inlet valve oil station startup control method further includes:

[0059] Step S800, extending the command pulse of the isolation valve.

[0060] The duration of the command pulse of the isolation valve is extended, specifically, it can be extended by 2 seconds.

[0061] In the conventional technology, the duration of the command pulse of the isolation valve is 8 seconds. After the command pulse fails for 7 seconds, the water inlet valve oil station fails and trips, thereby generating a fault signal, which can only last for 1 second. The server may have a preset time delay for the water inlet valve oil station failure, so the isolation valve opening failure trip function cannot be effectively implemented. For example, the preset time can be 2 seconds.

[0062] In this embodiment, the duration of the command pulse of the isolation valve is extended, thereby ensuring that the fault signal of the water inlet valve oil station can cover the server trip time, thereby allowing the isolation valve to trip in time when necessary.

[0063] In an exemplary embodiment, step S800 includes:

[0064] Step S810, extending the opening command pulse of the isolation valve;

[0065] Step S820, extending the closing command pulse of the isolation valve.

[0066] In step S810, the duration of the opening command pulse of the isolation valve is extended. For example, the duration of the opening command pulse of the isolation valve can be extended by 2 seconds. Specifically, the time of increasing the opening command timer can be set. Alternatively, the time of increasing the disconnection delay timer can be set.

[0067] In the conventional technology, after the time of the opening command timer is set to increase, when the oil pump stops running, the isolation valve opening command is interrupted, which may result in insufficient time for issuing the isolation valve opening command pulse. Therefore, in this embodiment, the timing of the opening command timer is changed from 10 seconds to 8 seconds. At the same time, the disconnection delay timer is added and the timing is set to 2 seconds, so as to ensure that the isolation valve opening command pulse is maintained for at least 2 seconds, and ensure that the maximum duration of the isolation valve opening command pulse is still 10 seconds.

[0068] In step S820, the duration of the closing command pulse of the isolation valve is extended. For example, the duration of the opening command pulse of the isolation valve can be extended by 2 seconds. Specifically, the time of increasing the closing command timer can be set.

[0069] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
