[0021] Example 1: This example provides a fuel measurement system, such as... Figure 1 Combination Figure 2 As shown, the system includes a base plate 1, a cover plate 3, a panel 4, a power module, a data acquisition module, and a control module 5. The base plate 1 has a mounting groove 2 on its surface. The cover plate 3 is hinged to the opening of the mounting groove 2 and is used to open or close the opening of the mounting groove 2. The panel 4 is disposed within the mounting groove 2. The power module is disposed on the side of the panel 4 near the bottom of the mounting groove 2 and is used to connect to a fuel level sensor. The data acquisition module is disposed on the side of the panel 4 near the bottom of the mounting groove 2, is connected to the power module, and is used to connect to the fuel level sensor.

[0022] For example, during implementation, an installation groove 2 is provided on the upper surface of the base plate 1.

[0023] One side of the cover plate 3 is hinged to one side of the mounting groove 2 through a hinge or other structure, so that the other side of the cover plate 3 can rotate around the hinge position in a direction closer to or away from the mounting groove 2, thereby closing or opening the mounting groove 2.

[0024] Panel 4 is connected to the mounting groove 2 by means of screw fixing, snap-fit, etc., and panel 4 is close to the groove opening of the mounting groove 2.

[0025] The power module is installed in the mounting slot 2 using screws or snap-fit ​​connectors, and is located on the side of the panel 4 closest to the bottom of the mounting slot 2. The power module can be connected to the fuel level sensor on the fuel tank via wires threaded through the panel 4.

[0026] The data acquisition module can be a Fluke 9500c data logger, a CR6 measurement and control data logger, or similar devices. The module is installed in the mounting slot 2 using screws or snap-fit ​​connectors, and is located on the side of panel 4 closest to the bottom of the mounting slot 2. The module is connected to the power module via wires, and can also be connected to the fuel level sensor on the fuel tank via wires threaded through panel 4.

[0027] Control module 5 can be a Kunlun Tongtai TPC7062Ti or Kunlun Tongtai TPC1061Ti touchscreen, etc. The configuration of control module 5 is as follows: Operating system: Windows 7 Professional; Intel Core i5 processor; Display: 10.1" IPS high-definition capacitive LCD touchscreen; RAM: 4GB; Hard drive: 64GB; Network card: one 10-1000M adaptive card. Control module 5 is mounted on panel 4 and connected to panel 4 via screws, clips, or other methods. The operation panel 4 of control module 5 is located on the side of control module 5 furthest from the bottom of mounting slot 2. Control module 5 is connected to both the power module and the data acquisition module via wires.

[0028] During use, when fuel measurement is required, first rotate the cover plate 3 away from the opening of the mounting slot 2 to open it. Next, connect the power module to the fuel level sensor on the fuel tank, and the data acquisition module to the fuel level sensor on the fuel tank via wires. Then, perform the test via the control module 5. After the test is complete, disconnect the power module from the fuel level sensor on the fuel tank, and disconnect the data acquisition module from the fuel level sensor on the fuel tank. Then, rotate the cover plate 3 towards the opening of the mounting slot 2 to close it. Integrating these components aims to improve the ease of use, maintenance, and versatility of the fuel measurement system.

[0029] Example 2: Based on Example 1 above, in this example, as follows... Figure 2 As shown, the power module includes a first power unit and a second power unit; the first power unit is used to connect to an external power source; the second power unit, the acquisition module, and the control module 5 are all connected to the first power unit, and the second power unit is used to connect to the fuel level sensor.

[0030] For example, in implementation, the power module includes a first power supply unit and a second power supply unit.

[0031] The first power supply unit can be an LM2576 power management board, an LM2670 power management board, or a WRB2412CS-1W power management board. The input terminal of the first power supply unit is used to connect to 27V DC power, and the input terminal of the first power supply unit is used to output 12V DC power.

[0032] The second power supply unit is a WOA75-220S12W(-DB). The input terminal of the second power supply unit is for receiving 12V DC power, and the output terminal is for outputting 5V DC power. This second power supply unit, the data acquisition module, and the control module 5 are all connected to the first power supply unit, and the second power supply unit is used to connect to the fuel level sensor.

[0033] During operation, the first power supply unit receives 27V DC and outputs 12V DC, which is then supplied to the control module 5, the data acquisition module, and the second power supply unit. This ensures that the control module 5 and the data acquisition module are powered on normally. Simultaneously, the second power supply unit outputs 5V DC to the fuel level sensor, enabling it to collect data from the fuel tank. This aims to meet the internal power supply requirements of the fuel level measurement system.
