It supports a full range of functions such as data caching, interrupted data transmission resume, remote data acquisition configuration management, and site configuration management. The data acquisition workstation can be remotely and centrally managed and maintained on the server.

[0003] Open the data collection station software, enter your username and password to log in, and follow the prompts on the software interface to perform the necessary initialization settings or configurations. Select an appropriate data collection method, such as scheduled collection or triggered collection. If using a questionnaire for data collection, you need to design the questionnaire content according to the collection objectives. Share the designed questionnaire with respondents via links or QR codes, and inform them of relevant precautions. Store the processed data in a secure and reliable data warehouse, such as a database or cloud storage.

[0004] However, existing workstations contain a large number of electronic components and assemblies. These components generate heat during operation. High-temperature environments negatively impact the performance and stability of electronic components. Excessive temperatures can reduce component reliability and may even cause malfunctions. Overheating can limit the performance of electronic components, leading to slower processing speeds, lower task execution efficiency, increased failure rates, and even hardware damage. This severely affects the accuracy and lifespan of data acquisition. Furthermore, dust can easily enter the device in the presence of external dust, causing damage. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Reference Figure 1-4 This is the first embodiment of the present invention, providing a portable data acquisition workstation, including a body 1. The inner wall of the body 1 has a cavity, and a display screen 3 is fixedly installed on the outer wall of the body 1. A base plate 2 is fixedly connected to the bottom of the body 1. Two fans 12 are installed on the inner wall of the cavity. The intake fan 12 is installed at a lower position of the body 1, which reduces the temperature at the lower position. The exhaust fan 12 is installed at a higher position of the body 1, which increases the temperature at the higher position, thus improving the heat dissipation efficiency. A filter plate 13 is slidably connected to the outer wall of the fan 12 and engages with the cavity. The filter plate 13 is used to prevent dust from entering the interior of the body 1. Four casters 6 arranged in a rectangular array and in contact with the ground are installed at the bottom of the base plate 2. The casters 6 facilitate the movement of the body 1. A pressure plate 9 is slidably connected to the bottom of the base plate 2. The pressure plate 9 is used to fix the position of the body 1. A soft pad 10 is fixedly connected to the bottom of the pressure plate 9.

[0027] The inner wall of the cavity is fixedly connected to a mounting bracket 11 that is fixedly installed on the outer wall of the fan 12. The inner wall of the body 1 has a slot for easy attachment of the filter plate 13. A knob 14 is slidably connected to the inner wall of the slot. Two rectangular blocks 15 that are mirror-distributed are fixedly connected to the outer wall of the knob 14.

[0028] The inner wall of the rectangular block 15 is slidably connected to a cylinder 16 that is fixedly connected to the inner wall of the slot. The inner wall of the slot is fixedly connected to a baffle that is slidably connected to the cylinder 16. The outer wall of the baffle has a through hole to facilitate the sliding of the rectangular block 15. The baffle is used to limit the movement of the knob 14. The inner wall of the filter plate 13 is slidably connected to a moving rod 17 that is slidably connected to the outer wall of the knob 14. The moving rod 17 is used to engage the filter plate 13. The top of the pressure plate 9 is fixedly connected to a push rod 8. The top of the push rod 8 is fixedly connected to a cylinder 7 that is fixedly installed on the inner wall of the base plate 2.

[0029] The outer wall of the moving rod 17 is slidably connected to a limiting post 18 that is slidably connected to the inner wall of the slot. The limiting post 18 is used to push the moving rod 17. A first spring 19 is connected between the inner wall of the slot and the outer wall of the limiting post 18. The first spring 19 is used to push the limiting post 18. The inner wall of the filter plate 13 is provided with two circular plates that are mirror-distributed and facilitate the sliding of the moving rod 17. The circular plates prevent the moving rod 17 from detaching from the inner wall of the filter plate 13.

[0030] During use, the fan 12 drives the external airflow through the filter plate 13 and into the interior of the machine body 1. Then, another fan 12 drives the airflow inside the machine body 1 to be discharged. Pushing the knob 14 moves the rectangular block 15 along the cylinder 16 to the inside of the baffle. The rectangular block 15 disengages from the cylinder 16. At the same time, the knob 14 presses the moving rod 17 to move. The moving rod 17 presses the first spring 19 through the limiting post 18. The first spring 19 retracts under force. Then, the knob 14 is rotated to move the rectangular block 15 along the baffle to prevent the first spring 19 from being released under force. The filter plate 13 is pulled away from the machine body 1 for cleaning. During installation, the filter plate 13 enters the inner wall of the machine body 1. The limiting post 18 retracts under force again. When the knob 14 is rotated to move the rectangular block 15 through the through hole, the first spring 19 moves the rectangular block 15 along the cylinder 16 to achieve the locking of the filter plate 13.

[0031] Example 2

[0032] Reference Figure 1 , Figure 2 and Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a plurality of cylindrical tubes 20 arranged in a rectangular array are fixedly connected to the bottom end of the substrate 2; a connecting post 22 that is fixedly connected to the top end of the universal wheel 6 is slidably connected to the inner wall of the cylindrical tubes 20; a plurality of sliders 24 arranged in a circular array are fixedly connected to the top end of the outer wall of the connecting post 22; and a groove is provided on the inner wall of the cylindrical tubes 20 to facilitate the sliding of the sliders 24.

[0033] A second spring 21 is connected between the inner wall of the cylinder 20 and the top of the connecting column 22. The second spring 21 is used to push the universal wheel 6. The top of the universal wheel 6 is fixedly connected to a plurality of positioning columns 23 arranged in a circular array and slidably connected to the inner wall of the cylinder 20. The positioning columns 23 are used to maintain the stability of the movement of the connecting column 22. A pusher 5 is fixedly connected to the top of the base plate 2. A solar panel 4 is installed on the top of the body 1.

[0034] During use, the pusher 5 drives the machine body 1 to move along with the caster wheel 6. When passing over a raised surface, the caster wheel 6 compresses the second spring 21 through the connecting column 22. The connecting column 22 drives the slider 24 to move along the groove. At the same time, the positioning column 23 enters the interior of the cylinder 20, and the second spring 21 is compressed. When the caster wheel 6 passes over a recessed surface, the second spring 21 is released, helping the wheel to smoothly overcome obstacles and keeping the caster wheel 6 in contact with the ground. When it moves to the appropriate position, the start cylinder 7 drives the pressure plate 9 to move through the push rod 8. The pressure plate 9 contacts the ground through the soft pad 10, fixing the position of the machine body 1. The operation is then complete.

[0035] The remaining structure is the same as that in Example 1.
