[0002] The power control cabinet integrates a large number of electronic equipment and instruments, and is connected to external equipment through lines. Regular maintenance is required during the use of the power control cabinet to avoid property losses and safety accidents caused by failures of the power control cabinet. Abnormal voltage, current and temperature inside the cabinet are one of the main causes of failure and damage of the power control cabinet. Therefore, voltage, current and temperature data need to be collected during the use of the power control cabinet.

[0003] In the prior art, manual regular inspections are generally used to troubleshoot power control cabinets. This troubleshooting and maintenance method relies entirely on manpower and cannot monitor the voltage, current, and temperature of the power control cabinet through real-time data collection and communication, which results in low troubleshooting and maintenance efficiency of the power control cabinet. To this end, we provide a power control cabinet data collection method and communication device based on the Internet of Things to solve the above problems. Summary of the invention

During the movement of the transmission rack 432, the transmission gear 433 is driven to rotate, thereby realizing the synchronous rotation of the second winding shaft 410. Under the joint action of the first transmission wheel 408, the second transmission wheel 412 and the first transmission belt 413, the second winding shaft 410 and the first winding shaft 406 are synchronously rotated. Figure 6 and Figure 7As shown, when the transmission rack 432 moves to drive the transmission gear 433 to rotate, the second winding roller 411 on the second winding shaft 410 rotates to gradually reel in the dust filter 415, and at the same time, the first winding roller 407 on the first winding shaft 406 rotates to gradually release the dust filter 415, thereby ensuring that the dust filter 415 is always in a taut state, which helps the dust filter 415 to be tightly attached to the inside of the circular mounting cavity 403.

[0037] In this embodiment of the present invention, a dust filter box 434 is fixedly installed on the surface of the heat dissipation bearing plate 3, a first flow pipe 435 connected to the dust filter box 434 is installed on one side thereof, a second flow pipe 436 connected to the dust filter box 434 is installed on the other side thereof, a negative pressure control cylinder 437 sleeved on the second screw 419 is installed on the top of the second flow pipe 436 (the two are rotatably matched), a negative pressure impeller located inside the negative pressure control cylinder 437 is installed on the other end of the second screw 419, and a solenoid valve 438 is installed on the second flow pipe 436; a dust storage box 439 is fixedly installed on one side of the scraper 417, and a dust drop opening is opened at the top of the dust storage box 439 close to the scraper 417, a vertical mounting plate 440 is fixedly installed on the surface of the first U-shaped frame 405, and an elastic element 441 is arranged on the surface of the vertical mounting plate 440; when the voltage and current data collected by the data acquisition module exceeds the set voltage and current working range or the temperature collected by the temperature monitoring module reaches the set temperature monitoring module inside the power control cabinet When the threshold is measured, the data processor 104 controls the cooling fan to start running, and controls the second motor 421 to start at the same time, and controls the first bevel gear 422 to rotate through the second motor 421, and the bevel gear ring 423 that rotates synchronously with the first bevel gear 422 drives the second bevel gear 424 to rotate, thereby realizing the rotation control of the second screw 419. When the second screw 419 is controlled to rotate, the third transmission wheel 427, the fourth transmission wheel 428 and the second transmission belt 429 jointly realize the synchronous rotation between the third screw 426 and the second screw 419. When the third screw 426 rotates, the second winding roller 411 on the second winding shaft 410 rotates so that the dust filter 415 is gradually wound up, and at the same time, the first winding roller 407 on the first winding shaft 406 rotates so that the dust filter 415 is gradually released, so that the dust filter 415 arranged between the second winding roller 411 and the first winding roller 407 is wound up and moved (that is, the dust filter 415 moves to the right direction, such as Figure 6 As shown), at the same time, the rotating second screw 419 drives the scraper 417 to move to the left, and then the scraper 417 scrapes off the dust attached to the surface of the dust filter 415, and the scraped dust enters the dust storage box 439 along the dust outlet.

[0038] When the flow port at the bottom of the ash storage box 439 moves to align with the first flow pipe 435 (at this time, the data processor 104 controls the solenoid valve 438 to open), the scraper 417 just disengages from the threaded structure on the second screw 419. At this time, the elastic element 441 is squeezed and compressed by the ash storage box 439. Subsequently, during the continued rotation of the second screw 419 and the third screw 426, the ash storage box 439 remains in this position and the flow port is connected to the first flow pipe 435. The negative pressure impeller rotating synchronously with the second screw 419 generates a negative pressure environment inside the second flow pipe 436, thereby allowing external air to enter the ash storage box 439 from the ash falling port. Under the action of the air flow, the accumulated dust in the ash storage box 439 enters the first flow pipe 435 along the flow port, and then enters the dust filter box 434 from the first flow pipe 435 to be filtered (a filter plate can be provided for easy replacement and cleaning). After the scraper 417 disengages from the threaded structure on the second screw 419, Since the rotation direction of the second screw 419 has not changed, the scraper 417 can no longer mesh with the second screw 419. At the same time, the elastic force of the elastic element 441 can ensure that the ash storage box 439 is at the position of the first flow pipe 435. After the transmission rack 432 moves to the specified position, the data processor 104 starts to control the second motor 421 to operate in the reverse direction, so that the second screw 419 and the third screw 426 start to rotate in the reverse direction (during the reverse rotation of the second screw 419, the elastic force of the elastic element 441 can ensure that the scraper 417 can be threadedly matched with the second screw 419), until the scraper 417 and the dust filter 415 return to their initial positions, thereby realizing dynamic cleaning of the dust filter 415 during the rotation and heat dissipation of the cooling fan to improve the flow performance of the air inlet mesh 402. When the monitored temperature in the cabinet returns to the normal range, the second motor 421 is controlled to be turned off by the data processor 104.
