[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0018] It should also be understood that the terms used in the present specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0019] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0020] To solve the technical problems mentioned in the background, the present invention provides Figure 1 An engine intelligent test system shown includes: a control module 1, including an identification unit 11 for identifying an engine to be tested, a control unit 12 for providing a program running environment, and control software for controlling the test module; a test module 2, including a placement table 21 for placing and fixing the engine to be tested, a peripheral connection component 22 for connecting the engine to be tested and providing test elements, and a transport component 23 for moving the engine to be tested; wherein the control software controls the peripheral connection component to provide the corresponding test elements according to the identification result of the engine to be tested.

[0021] The control module is a device, equipment or combination thereof that performs control functions, such as a computer or a common workbench or operation table in a factory. The recognition unit is a device used to recognize the characteristics of a target and output certain recognition results. For example, a camera can recognize the shape, a scanner can recognize specific text, numbers and letters, and a keyboard can input the corresponding value.

[0022] The test module is a hardware set for performing tests, and is mainly used to test the engine in the present invention. Among them, the engine is heavy and belongs to precision equipment. If a collision occurs during the test, the test results may be abnormal and the equipment may be damaged. Therefore, in combination with the structure of the engine, a concave-convex interval or a distance indication is set, and a buffer layer is installed to construct a placement platform. Setting a special placement platform can avoid the impact of the site on the equipment, and can also prompt others to enter the site with caution, effectively avoiding the occurrence of abnormal collisions. The engine is not an independent individual and needs other equipment or structures to match in order to really run. Therefore, setting a peripheral connection component can provide support for the normal operation of the engine, and the elements required for the operation of the engine are classified as test elements. The definition of the periphery is that these connection components are not the structure of the engine itself. Specifically, they can be linkage structures such as connecting rods, gears, and guide rails. Through these linkage structures, specific connection ports and engine interfaces are connected to achieve the injection of electricity, oil, air and other elements into the engine. The handling component includes a sling and a mobile component, which is used to transport the engine into or out of the placement platform.

[0023] The test elements include fuel, and the peripheral connection components include a plurality of fuel interfaces; correspondingly, the control software is provided with a fuel pressure matching subroutine for determining the matching fuel pressure and controlling the corresponding fuel interface according to the identification result, so as to realize the injection of fuel into the engine to be tested.

[0024] The engine is generally a gas engine, which achieves power output by burning oil to drive the piston. Therefore, one of the test elements includes pre-filled fuel. Different types of fuel should not be mixed together, and different fuel interfaces are required to provide them. At the same time, different engines or engines in different working conditions have pressure requirements when injecting fuel. Different fuel interfaces can be set to provide different fuel pressures. In order to ensure the accuracy of the test results, it is necessary to set a fuel pressure matching subroutine in the control software, which can determine the pressure of the matching fuel based on the identification results and control the corresponding fuel interface to inject fuel into the engine to be tested.

[0025] The fuel pressure includes: below 1.5 Bar and above 4.2 Bar.

[0026] The test module is provided with a fuel inlet pipeline; the fuel inlet pipeline includes a check valve for preventing backflow after pressurization, and a reserved three-way pipe for connecting to the boost pump.

[0027] The test element includes electricity, the peripheral connection component includes a power supply, and correspondingly, the rated voltage of the boost pump is 24V.

[0028] The identification unit identifies the engine to be tested based on at least one of manual input, appearance recognition, nameplate reading and weight matching.

[0029] The test module also includes a fuel consumption meter.

[0030] The placement table is provided with a fixed buckle group; correspondingly, the control unit is used to select a suitable fixed buckle from the fixed buckle group according to the structure of different types of engines, and determine the movement parameters of the peripheral connection component according to the locking condition of the fixed buckle.

[0031] like Figure 2 The intelligent oil circuit identification and boosting system shown includes software and hardware requirements, specifically:

[0032] Software control requirements:

[0033] Identify the engine based on its model.

[0034] The software is set with AB channels: when the pre-fill fuel pressure is below 1.5Bar, channel A is used to implement it, and when the pre-fill fuel pressure is above 4.2Bar, channel B is used to implement it.

[0035] Through system control, the normal model's pre-filled fuel pressure of 1.5Bar corresponds to channel A, and the model's pre-filled fuel pressure of 4.2Bar corresponds to channel B, to achieve automatic channel cut-off.

[0036] Hardware modification requirements:

[0037] A check valve is installed on the fuel inlet pipeline to prevent backflow after pressurization; two additional tees are set in the fuel inlet pipeline to facilitate the addition of a boost pump, and the pipe diameter remains the same as the original; the boost pump requires 24V voltage to start, which needs to be obtained from the power supply; identification is performed according to the engine model (manual input).

[0038] The engine obtains fuel from the oil pipeline, which consists of two sections. One section is equipped with a 1.5 bar refueling pump (original oil pump), and the other section is connected to the engine through a G1 / G2 tee + tapered tee pipe to add fuel of different pressures. The check valve is used to prevent the oil delivery of another section from affecting other sections. The engine can output various parameters by itself or test various parameters of the engine through external sensors, and then return to the fuel temperature control unit, which can control the pressure, injection and temperature of the fuel and output the data to the fuel consumption meter.

[0039] After the engine's shape is finalized, its size is basically fixed. Therefore, precise control can be achieved through a combination of tracks, speed controllers, stepper motors, etc. to complete structural docking.

[0040] Those of ordinary skill in the art will appreciate that the units of each example described in conjunction with the embodiments disclosed in this embodiment can be implemented with electronic hardware, computer software, or a combination of the two. In order to clearly illustrate the interchangeability of hardware and software, the composition of each example has been generally described in terms of function in the above description. Whether these functions are performed in hardware or software depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of the present invention.

[0041] In the embodiments provided in the present application, it should be understood that the division of units is merely a logical function division, and there may be other division methods in actual implementation, for example, multiple units may be combined into one unit, one unit may be split into multiple units, or some features may be ignored.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
