[0041] When the oil return hose is connected to the oil outlet of the aircraft hydraulic system and absorbs oil from the oil outlet, the oil return control module controls the first oil return solenoid valve and the second oil return solenoid valve to open through the second electric wire;

[0042] The aviation hydraulic oil pump truck is a self-propelled oil pump truck. When the oil outlet hose and oil return hose are still connected to the aircraft, if the person in the oil pump truck cab mistakenly operates and starts the oil pump truck away from the aircraft, the oil outlet hose and oil return hose will be stretched;

[0043] When the oil outlet hose is stretched, as the pulling force increases, the first electric wire is pulled off before the middle section of the oil outlet hose, and as the pulling force continues to increase, the middle section of the oil outlet hose is pulled off before the front section and the rear section of the oil outlet hose, that is, the oil outlet hose will be pulled off at the middle section; and the first oil outlet solenoid valve and the second oil outlet solenoid valve are provided at both ends of the middle section of the oil outlet hose. Since the first oil outlet solenoid valve and the second oil outlet solenoid valve are both normally closed valves, when the first electric wire is pulled off, the first oil outlet solenoid valve and the second oil outlet solenoid valve will be powered off and closed. Therefore, after the oil outlet hose is pulled off, the front section of the oil outlet hose connected to the oil inlet of the aircraft hydraulic system is closed by the first oil outlet solenoid valve, and the rear section of the oil outlet hose is closed by the second oil outlet solenoid valve. Therefore, the oil inlet of the aircraft hydraulic system will not continue to leak, and the rear section of the oil outlet hose will not continue to leak.

Since the first oil return solenoid valve and the second oil return solenoid valve are both normally closed valves, when the second electric wire is pulled off, the first oil return solenoid valve and the second oil return solenoid valve will be powered off and closed. Therefore, after the oil return hose is pulled off, the front section of the oil return hose connected to the oil outlet of the aircraft hydraulic system is closed by the first oil return solenoid valve, and the rear section of the oil return hose is closed by the second oil return solenoid valve. Therefore, the oil outlet of the aircraft hydraulic system will not continue to leak, and the rear section of the oil return hose will not continue to leak.

[0045] As can be seen from the above, the present invention can prevent the oil pump truck and the aircraft hydraulic system from continuously leaking after the oil outlet hose and / or the oil return hose are pulled off;

[0046] The oil outlet control module is provided with a first current detection unit, which detects the current of the first wire. When the current of the first wire is abnormal due to the first wire being broken, the first current detection unit detects the abnormality and uploads an oil outlet hose abnormality alarm signal to the vehicle information processing computer;

[0047] The oil return control module is provided with a second current detection unit, which detects the current of the second wire. When the current of the second wire is abnormal due to the second wire being broken, the second current detection unit detects the abnormality and uploads an oil return hose abnormality alarm signal to the vehicle information processing computer;

[0048] The vehicle-mounted information processing computer receives and displays the oil hose abnormality alarm signal and the oil return hose abnormality alarm signal, and the vehicle-mounted information processing computer uploads the oil hose abnormality alarm signal and the oil return hose abnormality alarm signal to the remote monitoring center;

[0049] The remote monitoring center receives and displays the oil hose abnormality alarm signal and the oil return hose abnormality alarm signal;

[0050] As can be seen from the above, the present invention can send out an abnormal alarm signal when the oil outlet hose and / or the oil return hose is accidentally stretched to a certain extent (that is, when the first wire and / or the second wire is broken).

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
