[0034] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application, however, can be practiced without the specific details.

The appearances of "in one embodiment" or "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily all referring to a single, alternative embodiment, or a single implementation.

[0036] Embodiment 1, with reference to Figures 1-13 For the first embodiment of the present application, the embodiment provides a power distribution automation fault monitoring and self-healing terminal device.

[0037] The mounting seat 101 can be fixed by bolts, the sealed shell 102 is used for sealing the mounting seat 101, a ventilation opening is formed on the surface of the sealed shell 102 for heat dissipation of the terminal device, the card seat 103 is used for connecting the SMI card 104 to realize the wireless communication function of the terminal device, the network interface 105 is used for connecting the crystal head 106, so that the terminal device can perform wired communication, and the data transmission and communication between the terminal device and the master station or other intelligent devices are facilitated, the power module 107 is used for supplying power to various electrical equipment, and the circuit board 108 is integrated with a monitoring module, a communication module, a restart control module and a delay control module.

[0038] When the monitoring module detects that the communication module cannot normally communicate, the restart control module can control the terminal device to restart, at which time the delay control module enters a timing state, so that the terminal device is connected to the circuit after a certain timing, so that the terminal device is restarted. The above circuit connection is the prior art, and those skilled in the art clearly know that it is not repeated here. When the terminal device is restarted three times and cannot make the communication normal, the plug-in assembly can be started to plug and unplug the SMI card 104 and the crystal head 106, so that the SMI card 104 and the crystal head 106 are reconnected, the communication failure caused by poor contact or looseness is solved, and the reliability of the communication connection is improved.

[0039] The plug-in assembly 200 is arranged in the mounting seat 101 and includes a support seat 201a fixed to the bottom wall in the mounting seat 101. A moving shell 201b is slid on the top of the support seat 201a. A limiting strip 201c is fixed to the bottom of the moving shell 201b and slides in the moving shell 201b. A moving seat 201d slides in the moving shell 201b. A support plate 201e is fixed to one side of the moving shell 201b. A first spring 201f is fixed to one side of the support plate 201e. The other end of the first spring 201f is fixed to one side of the moving seat 201d. A driving block 201g is fixed to the inner wall of the moving shell 201b. A driving groove 201d-1 is arranged on one side of the moving seat 201d. The driving block 201g slides in the driving groove 201d-1.

[0040] The support seat 201a is used for supporting the moving shell 201b. The limiting strip 201c is arranged to enable the moving shell 201b to stably move on the top of the support seat 201a. The moving seat 201d is used for fixedly supporting the card seat 103 and the network interface 105. The moving seat 201d can drive the card seat 103 and the network interface 105 to synchronously move. The support plate 201e is used for supporting the first spring 201f. The first spring 201f is in a compressed state and is used for pushing the moving seat 201d. The driving block 201g is used for driving the moving seat 201d to move and limiting the position of the moving seat 201d.

[0041] When the moving shell 201b moves away from the inner wall of the mounting seat 101, the first spring 201f is reset and elongated. The moving seat 201d is still close to one side of the inner wall of the mounting seat 101. At this time, the driving block 201g slides in the driving groove 201d-1 until the driving block 201g slides to the end of the driving groove 201d-1. The moving seat 201d can be pushed to move away from the inner wall of the mounting seat 101, so as to drive the card seat 103 and the network interface 105 to move.

[0042] Specifically, the plug-pull assembly 200 further comprises a driving member 202 arranged in the mounting seat 101, which comprises a fixing seat 202a fixed to the bottom of the mounting seat 101, a driving motor 202b fixed to the top of the fixing seat 202a, a driving disc 202c fixed to the output end of the driving motor 202b, and a driving column 202d fixed to the end of the driving disc 202c.

[0043] The fixing seat 202a is used for supporting the driving motor 202b, the driving motor 202b can drive the driving disc 202c to rotate, so that the driving disc 202c drives the driving column 202d to move in a circle, the driving motor 202b is a servo motor, a controller is arranged on the servo motor, which is used for receiving instructions from a power distribution automation fault monitoring system and controlling the servo motor to act according to the instructions, and the power module 107 can be used for supplying power to the servo motor.

[0044] Specifically, the driving member 202 further comprises a driving plate 202e fixed to one side of the moving shell 201b, the driving plate 202e is provided with an arc-shaped groove 202e-1 and a straight groove 202e-2, and the driving column 202d is slidable in the arc-shaped groove 202e-1 and the straight groove 202e-2.

[0045] When the driving disc 202c rotates, the driving column 202d can slide from the arc-shaped groove 202e-1 into the straight groove 202e-2, and then slide from the straight groove 202e-2 into the arc-shaped groove 202e-1, so as to extrude the inner walls of the arc-shaped groove 202e-1 and the straight groove 202e-2 by the driving column 202d, so that the driving plate 202e drives the moving shell 201b to move, when the moving shell 201b moves to the farthest end of its stroke, the driving column 202d slides in the arc-shaped groove 202e-1, at this time, since the arc-shaped groove 202e-1 and the driving disc 202c are concentric circles, the driving column 202d will not drive the driving plate 202e to move when moving, so that the moving shell 201b stays in place at this time, the short stay time allows the static electricity on the SMI card 104 and the card seat 103 to have the opportunity to gradually dissipate through the air, although the degree of dissipation may be limited, but it can reduce the potential damage of static electricity to the SMI card 104 or the card seat 103 to a certain extent.

[0046] Specifically, the plug-pull assembly 200 further comprises a positioning member 203 arranged in the mounting seat 101, which comprises a supporting shell 203a fixed to the mounting seat 101, a positioning column 203b slidably arranged in the supporting shell 203a, a pressing plate 203c fixed to the end of the positioning column 203b, a positioning groove 203c-1 arranged on one side of the pressing plate 203c, a chamfer 203c-2 arranged at the end of the pressing plate 203c, and a supporting frame 203d fixed in the mounting seat 101.

[0047] The support shell 203a is used for supporting the positioning column 203b, the positioning column 203b is used for pressing down the pressing plate 203c, so that the pressing plate 203c extrudes the SMI card 104, through the setting of the chamfer 203c-2, the SMI card 104 can be easily inserted into the card seat 103, the positioning groove 203c-1 is used for positioning the SMI card 104, and the support frame 203d is used for supporting the bottom of the SMI card 104. Through the cooperation of the support frame 203d and the pressing plate 203c, the SMI card 104 can be positioned.

[0048] Specifically, the positioning member 203 further includes a second spring 203e fixed to the top wall in the support shell 203a, and the other end of the second spring 203e is fixed with a lifting ring 203f fixed to the surface of the positioning column 203b.

[0049] The second spring 203e is in a compressed state, and the lifting ring 203f is used to drive the positioning column 203b to move up and down.

[0050] Specifically, the lifting ring 203f slides with an insertion block 203g, the insertion block 203g is provided with a third spring 203h, one side of the insertion block 203g is provided with an extrusion block 203i, and the support shell 203a is provided with a sliding groove 203a-1 and an insertion slot 203a-2. The insertion block 203g slides in the sliding groove 203a-1, and the extrusion block 203i is inserted into the insertion slot 203a-2.

[0051] The insertion block 203g slides in the sliding groove 203a-1, thereby limiting the angle of the lifting ring 203f, preventing the lifting ring 203f from rotating, and the third spring 203h is in a compressed state. When the moving shell 201b moves away from the extrusion block 203i, the insertion block 203g can push the extrusion block 203i, at this time, the insertion block 203g can be inserted into the insertion slot 203a-2, and the lifting ring 203f can be limited, so that the lifting ring 203f cannot move in the support shell 203a, thereby fixing the positioning column 203b and the pressing plate 203c, so that the pressing plate 203c and the support frame 203d can stably clamp the SMI card 104.

[0052] Embodiment 2, refer to Figure 2 , Figures 7-9 , Figure 12 and Figure 13 , which is a second embodiment of the present application, based on the previous embodiment.

[0053] Specifically, the plug-in assembly 200 further comprises a taking-out piece 204 arranged in the mounting base 101, which comprises a supporting shaft 204a fixed in the mounting base 101, a swing lever 204b rotationally connected to the surface of the supporting shaft 204a, and a torsion spring arranged between the supporting shaft 204a and the swing lever 204b. A button 204c is slidably arranged in the mounting base 101.

[0054] The supporting shaft 204a is used for supporting the swing lever 204b, and the torsion spring arranged between the supporting shaft 204a and the swing lever 204b is used for resetting the swing lever 204b. By pressing the button 204c, the button 204c can extrude one end of the swing lever 204b, so that the other end of the swing lever 204b can push the SMI card 104, thereby moving the SMI card 104 outward, so as to facilitate taking out the SMI card 104.

[0055] Specifically, the plug-in assembly 200 further comprises a clamping piece 205 arranged in the mounting base 101, which comprises a supporting frame 205a fixed in the mounting base 101, a clamping block 106-1 arranged on the top of the crystal head 106, and a clamping groove 205a-1 formed in the inner wall of the supporting frame 205a, and the clamping block 106-1 is clamped in the clamping groove 205a-1.

[0056] The supporting frame 205a is used for supporting the crystal head 106, and the inner wall of the supporting frame 205a is tightly attached to the surface of the crystal head 106. By clamping the clamping block 106-1 in the clamping groove 205a-1, the crystal head 106 can be positioned.

[0057] Specifically, the clamping piece 205 further comprises a rotating shaft 205b fixed in the mounting base 101, a cam 205c fixed on the surface of the rotating shaft 205b, a driving arm 205d fixed on the surface of the cam 205c, a fourth spring 205e fixed on one side of the driving arm 205d, a supporting block 205f fixed on the other end of the fourth spring 205e, and the supporting block 205f is fixed in the mounting base 101.

[0058] The fourth spring 205e is in a stretched state. By the resetting tension of the fourth spring 205e, the driving arm 205d can drive the cam 205c to rotate, so that the cam 205c can extrude the surface of the crystal head 106, thereby improving the stability of the crystal head 106 in the supporting frame 205a and preventing the crystal head 106 from moving.

[0059] Specifically, the clamping piece 205 further comprises a supporting rod 205g fixed in the mounting base 101, a rotating base 205h rotatably connected to the surface of the supporting rod 205g, and two adjusting rods 205i hingedly connected in the rotating base 205h. One side of the driving arm 205d is fixed with a connecting base 205j, and the other adjusting rod 205i is hingedly connected to the surface of the connecting base 205j. The two adjusting rods 205i are hingedly connected to each other. One side of the rotating base 205h is fixed with a fifth spring 205k, and the other end of the fifth spring 205k is fixed to one side of the connecting base 205j.

[0060] The supporting rod 205g is used to support the rotating base 205h, and the rotating base 205h is used to support the adjusting rods 205i. When the moving shell 201b moves away from the adjusting rods 205i, the two adjusting rods 205i can be caused to move close to each other under the pulling force of the fifth spring 205k. At this time, the connecting base 205j can drive the driving arm 205d to move, so that the cam 205c can extrude the surface of the crystal head 106.

[0061] When the moving shell 201b moves close to the adjusting rods 205i, the two adjusting rods 205i can be extruded to move away from each other. At this time, the adjusting rods 205i can push the driving arm 205d through the connecting base 205j, so that the driving arm 205d drives the cam 205c to reset, thereby releasing the extrusion of the cam 205c on the crystal head 106.

[0062] In use, when the monitoring module detects that the communication module cannot normally communicate, the restart control module can control the terminal device to restart. At this time, the delay control module enters a timing state, so that the terminal device is connected to the circuit after a certain timing, so that the terminal device is restarted. When the terminal device is restarted for three times and the communication is still not normal, the driving motor 202b can be started to slowly rotate the output end of the driving motor 202b for one circle.

[0063] During the rotation of the output end of the driving motor 202b, the driving disc 202c drives the driving column 202d to move in a circle, and the driving column 202d extrudes the inner walls of the arc-shaped groove 202e-1 and the straight groove 202e-2, so that the driving plate 202e drives the moving shell 201b to move. The moving shell 201b first moves away from the inner wall of the mounting base 101. When the moving shell 201b moves away from the inner wall of the mounting base 101, the first spring 201f resets and elongates. The moving base 201d is still close to one side of the inner wall of the mounting base 101. At this time, the driving block 201g slides in the driving groove 201d-1.

[0064] Firstly, the moving shell 201b moves away from the pressing block 203i, and the plug block 203g can push the pressing block 203i. At this time, the plug block 203g can be plugged into the plug slot 203a-2, and the lifting ring 203f can be limited so as to be unable to move in the support shell 203a, thereby fixing the positioning column 203b and the pressing plate 203c, so that the pressing plate 203c and the support frame 203d can stably clamp the SMI card 104.

[0065] Meanwhile, with the movement of the moving shell 201b, the moving shell 201b moves away from the two adjusting rods 205i, so that the two adjusting rods 205i can move close to each other under the pulling force of the fifth spring 205k. At this time, the connecting seat 205j can drive the driving arm 205d to move, so that the cam 205c can extrude the surface of the crystal head 106, thereby improving the stability of the crystal head 106 in the support frame 205a, and preventing the crystal head 106 from moving.

[0066] With the continuous movement of the moving shell 201b, the driving block 201g slides to the end of the driving slot 201d-1, and the moving seat 201d is pushed, so that the moving seat 201d moves away from the inner wall of the mounting seat 101, thereby driving the card seat 103 and the network interface 105 to move, so that the card seat 103 and the network interface 105 are separated from the SMI card 104 and the crystal head 106 respectively.

[0067] When the moving shell 201b moves to the farthest end of its stroke, the driving column 202d slides in the arc-shaped slot 202e-1. At this time, since the arc-shaped slot 202e-1 and the driving disc 202c are concentric circles, the driving column 202d does not drive the driving plate 202e to move when moving, so that the moving shell 201b stays in place at this time. The short stay time allows the static electricity on the SMI card 104 and the card seat 103 to have the opportunity to gradually dissipate through the air. Although the degree of dissipation may be limited, it can reduce the potential damage of static electricity to the SMI card 104 or the card seat 103 to a certain extent.

[0068] At this time, with the rotation of the driving disc 202c, the moving shell 201b moves to reset. Firstly, the card seat 103 and the network interface 105 are re-sheathed on the surface of the SMI card 104 and the crystal head 106. When the moving shell 201b moves close to the adjusting rod 205i, the two adjusting rods 205i can be extruded, so that the two adjusting rods 205i move away from each other. At this time, the adjusting rod 205i can push the driving arm 205d through the connecting seat 205j, so that the driving arm 205d drives the cam 205c to reset, thereby releasing the extrusion of the cam 205c on the crystal head 106.

[0069] When the moving shell 201b pushes the extrusion block 203i, the extrusion block 203i can push the plug block 203g out of the slot 203a-2, thereby releasing the limit on the lifting ring 203f.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalent replaced without departing from the spirit and scope of the technical solutions of the present application, and all of them should be covered in the scope of the claims of the present application.
