[0024] like Figure 1-3As shown, the utility model proposes a remote-controlled pressure plate device, including multiple pressure plate bodies, the pressure plate body including a first terminal 1, a second terminal 2, a base 3 and a connecting piece 4, the first terminal 1 and the second terminal 2 are assembled on both sides of the base 3, and an iron core 5 is provided in the second terminal 2; the connecting piece 4 is movably arranged on the first terminal 1, and a permanent magnet is provided on the side thereof moving toward the iron core 5, wherein the magnetic pole of the permanent magnet close to the iron core 5 is the N pole, and a coil 6 is wound on the outer wall of the iron core 5, and a sensor control component 7 is electrically connected to the coil 6 of each pressure plate body, and the sensor control component 7 includes a control module 8, a power supply 9 and a communication module 10, the control module 8 is electrically connected to the power supply 9 and the communication module 10 respectively, the power supply 9 is provided on the coil 6 to generate current on the coil 6, and the communication modules 10 between each sensor control component 7 are connected in parallel. The remote-controlled pressure plate device also It includes a pressure plate controller 11, an intelligent gateway 12 and an Internet of Things platform server 13. The intelligent gateway 12 is connected to the Internet of Things platform server 13 through wireless transmission. The intelligent gateway 12 is electrically connected to the pressure plate controller 11. The communication module 10 adopts RS485 networking to be electrically connected to the pressure plate controller 11, so that the Internet of Things platform is connected to the pressure plate controller 11 through the intelligent gateway 12 device, and a signal is sent to the intelligent gateway 12 through the Internet of Things platform server 13. The intelligent gateway 12 feeds back the signal to the pressure plate controller 11, and the pressure plate controller 11 feeds back the signal to the communication module 10. Finally, after the communication module 10 transmits the signal to the control module 8, the control module 8 controls the direction of the current generated by the power supply 9 on the coil 6 to adjust the magnetic pole on the side of the iron core 5 in contact with the permanent magnet, so as to realize the switching between the closed or disconnected state between the connecting piece 4 and the iron core 5.

[0025] like Figure 1 As shown, in this embodiment, the power supply 9 supplies power to the coil 6. Under normal conditions, when the coil 6 is energized, according to the right-hand screw rule, the upward magnetic pole of the core 5 is the north pole. Since the permanent magnet provided on the connecting piece 4 has the north pole close to the upward magnetic pole of the core 5, when the connecting piece 4 approaches the core 5, the connecting piece 4 and the core 5 will repel each other, so that the connecting piece 4 and the core 5 are always in a disconnected state, thereby avoiding the accident of closing due to misoperation. Figure 2As shown, when the control module 8 receives the signal fed back by the communication module 10, the control module 8 changes the direction of the current delivered to the coil 6 by the power supply 9. According to the right-hand screw rule, the upward magnetic pole of the iron core 5 is the S pole at this time, and since the permanent magnet arranged on the connecting piece 4 has the magnetic pole close to the upward side of the iron core 5 at the N pole, when the connecting piece 4 is close to the iron core 5, the connecting piece 4 and the iron core 5 will attract each other, so that the connecting piece 4 and the iron core 5 are always in a connected and closed state, thereby avoiding the accident of disconnection due to misoperation, so that the connection state of the connecting piece 4 and the iron core 5 can be effectively and automatically controlled, and the Internet of Things platform server 13 sends the operation instructions for the pressure plate to avoid the problem of human misoperation, thereby improving the reliability and safety of the pressure plate operation. At the same time, the structure is simple, the control is reliable, and it is easy to use.

[0026] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention.
