[0048] The data recording unit includes a non-volatile NOR Flash, to which the MCU is connected via a high-speed SPI bus. The vibration data during the transport monitoring process and its corresponding timestamp, power, and system status information are stored in the unit in real time. After the transport monitoring is completed, the recorded data can be read for users to print, export, and analyze data.

[0049] The Bluetooth printing module, including a low-power Bluetooth module and a PCB onboard antenna, enables the wireless printing of vibration data, effectively reducing the connection cables between the device and peripherals, and provides a basis for the device's design requirements for small size, integration, and high waterproofness.

[0050] In this embodiment, the housing includes a mounting housing 1, a mounting base 2 and a main control PCB board 9;

[0051] The installation housing 1 is designed as a rectangular housing, and its bottom is open. The surface of the installation housing 1 is provided with:

[0052] Liquid crystal limiting groove 3, used for setting the liquid crystal display screen;

[0053] Indicator light guide column 4, used to set the indicator light;

[0054] The button straight-through groove 5 is used to set the touch button spring and is connected to the touch button;

[0062] When the device is in use, firstly, a fixed connection is adopted for the mounting shell and the mounting base 2, instead of the traditional transport seismometer upper and lower shell cover buckle design. Therefore, the device has stronger waterproof performance and is not easily affected by external factors. In addition, through the overall design of the mounting shell, the device can be operated or the status of the device can be checked on the surface of the mounting shell, which is easy to use.

When the mounting base 2 and the mounting shell 1 are locked by screws, the mounting base 2 will squeeze the sealing gasket 7 until the mounting base 2 and the mounting shell 1 are completely locked. At this time, the sealing gasket 7 has been completely squeezed, and the air on both sides thereof will be isolated, thereby ensuring the waterproof and dustproof properties between the mounting shell 1 and the mounting base 2.

The mounting base 2 and the mounting shell 1 are connected by inserting screws and screwing them together with the bottom threaded holes 14 of the mounting shell 1 to complete the connection.

[0066] In this embodiment, the four corners of the installation housing 1 are provided with main control PCB board height limiting steps 15, and the surface of the main control PCB board height limiting step 15 is provided with a main control PCB board mounting hole 16, and the inner end of the main control PCB board height limiting step 15 is rounded and the outer side is beveled, which is adapted to the inner cavity of the installation housing 1;

[0067] The four corners of the sealing gasket installation groove 6 are designed to be cut corners, which are staggered with the positions of the screw holes;

[0068] The above design can further simplify the overall size of the device to a great extent, making the product more compact and more space-efficient.

[0069] In this embodiment, four key through slots 5 are provided and are laterally distributed on the surface of the mounting housing 1 .
