In this way, the electrical components in the edge computing device are damaged due to the bad environment, resulting in the technical problem that the inspection cannot be performed.

[0050] The shielding signal of the embodiment can be from the ground control center 110, and the specific implementation is that the shielding signal or the recovery signal sent by the ground control center 110 is received. It can also be from the humidity meter arranged outside the edge device box body, and the specific implementation is that the humidity meter is electrically connected with the edge computing device main body 3, when the humidity meter measures that the external environment humidity exceeds the humidity threshold, the shielding signal is sent to the edge device main body, and when the humidity meter measures that the external environment humidity is lower than the humidity threshold, the recovery signal is sent to the edge computing device main body 3.

[0051] In some embodiments, the shielding waterproof mechanism 2 further comprises a rotating shaft, a rotating sleeve, a rotating motor 24 and a first bearing 25, and the side of the edge computing device box body 1 for installing the waterproof cloth 23 is provided with a mounting groove, two end faces in the mounting groove are respectively provided with the rotating motor 24 and the first bearing 25, one end of the rotating shaft is sleeved with the rotating motor 24, the other end of the rotating shaft is sleeved with the first bearing 25, and the rotating sleeve is fixedly sleeved on the rotating shaft and is fixedly connected with the edge side of the waterproof cloth 23.

[0053] In the embodiment, the first bearing 25 is only named for the convenience of distinguishing from other bearings, and is not used to limit a certain bearing.

[0054] The mounting groove of the embodiment is used to install the shielding waterproof mechanism 2, when the edge computing device main body 3 receives the shielding signal, the rotating motor 24 and the shielding motor 21 are controlled to rotate in the first direction synchronously, so that the waterproof cloth 23 is shielded on the edge computing box while being pulled and released. When the edge computing device main body 3 receives the recovery signal, the rotating motor 24 and the shielding motor 21 are controlled to rotate in the second direction synchronously, so that the waterproof cloth 23 is driven to return to the original position while being wound on the edge sleeve.

[0055] The first bearing 25 enables the rotating shaft to rotate independently relative to the edge computing box, and also plays a supporting role.

[0056] In some embodiments, as shown in FIG. 8, the waterproof cloth 23 is arranged on the edge computing device box body 1 in a roll shape, and the shielding waterproof mechanism 2 comprises a shielding motor 21, a rotating motor 24 and a first bearing 25. Figures 2-3As shown, the rod mechanism 22 comprises a rotating connecting shaft 221, a connecting rod 222 and a push-pull rod 223, one end of the rotating connecting shaft 221 is sleeved on the corresponding output end, the other end penetrates through the through hole and is connected to the connecting rod 222, the end of the connecting rod 222 is installed at the corresponding end of the push-pull rod 223, and the connecting rod 222 is driven by the synchronous belts of the shielding motor 21 and the rotating motor 24 to make the tarpaulin 23 just shield the end face of the edge computing device box 1.

[0057] In this embodiment, the shielding motor 21 drives the rotating connecting shafts 221 of the two output ends to rotate synchronously, and the rotating connecting shafts 221 drive the connecting rods 222 to rotate, at this time, the connecting rods 222 pull the drag link to drive the tarpaulin 23 to expand or retract. The arrangement of the push-pull rod 223 can flatten the tarpaulin 23 to shield above the edge computing device box, and also facilitates the retraction of the tarpaulin 23.

[0058] In some embodiments, the shielding waterproof mechanism 2 further comprises an outer rotating shaft 26, a second bearing and a clutch device, the outer rotating shaft 26 is sleeved on the rotating shaft through the second bearing and the clutch device, one end of the tarpaulin 23 is fixedly connected to the outer rotating shaft 26;

[0059] The clutch device is electrically connected with the edge computing main body, in the case of determining that the edge computing device box 1 needs to be shielded, the clutch device is in a separated state, the outer rotating shaft 26 rotates independently relative to the rotating sleeve, the edge computing device main body 3 controls the rotating motor 24 to be closed and the shielding motor 21 to be started, so that the tarpaulin 23 is unfolded from the outer rotating shaft 26 and shields the edge computing device box under the driving of the shielding motor 21, in the case of determining that the edge computing device box 1 needs to be shielded, the clutch device is in a connected state, the outer rotating shaft 26 is connected to the rotating sleeve, the edge computing device main body 3 controls the rotating motor 24 and the shielding motor 21 to be started, so that the tarpaulin 23 is wound on the outer rotating shaft 26 under the synchronous rotation of the rotating motor 24 and the shielding motor 21.

[0061] When the clutch device is in the separated state, the clutch device enables the outer rotating shaft 26 to rotate independently relative to the rotating shaft, at this time, the rod mechanism 22 can pull the tarpaulin 23 to unfold from the outer rotating shaft 26 without obstacles. When the clutch device is in the connected state, the clutch device enables the outer rotating shaft 26 to be connected with the rotating shaft as a whole, at this time, the tarpaulin 23 can be wound on the outer rotating shaft 26 under the driving of the rotating shaft.

The fault detection circuit is electrically connected with the main processing component and the one-way valve switching circuit respectively, and is configured to detect whether the main processing component is faulty. It can be understood that if the fault detection circuit has an output signal, it indicates that the main processing component is faulty. If the fault detection circuit does not output a signal, it indicates that the main processing component is not faulty. The ground control center 110 outside the edge computing box body is communicatively connected with the main processing component and the backup processing component respectively. When the fault detection circuit outputs a signal to the main processing component, the main processing component sends a starting signal to the starting circuit. The starting circuit responds to the starting signal, triggers the one-way valve switching circuit to disconnect the communication connection between the main processing component and the ground control center 110, and turns on the communication connection between the backup processing component and the ground control center 110.

[0066] It should be noted that when the main processing component does not receive a fault signal, the collected data is analyzed and processed by the main processing component. If the main processing component receives a fault signal, the backup processing component is switched to analyze and process the collected data.
