In the process of eliminating the problems, it was found that many problems of distribution terminals, such as remote control failure, poor signal, and device offline, can be solved by restarting the device and restarting the communication module.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1, reference Figures 1 to 13 , which is the first embodiment of the present invention, and this embodiment provides a distribution automation fault monitoring and self-healing terminal device. The distribution automation fault monitoring and self-healing terminal device includes a main component 100, including a mounting base 101, a sealing shell 102, a card base 103, an SMI card 104, a network interface 105, a crystal head 106, a power module 107 and a circuit board 108. The sealing shell 102 is fixed to the surface of the mounting base 101, the card base 103 is arranged in the mounting base 101, the SMI card 104 is plugged into the card base 103, the network interface 105 is arranged in the mounting base 101, the crystal head 106 is plugged into the network interface 105, and the power module 107 and the circuit board 108 are both fixed in the mounting base 101.

[0037] The mounting base 101 can be fixed by bolts, the sealing shell 102 is used to seal the mounting base 101, and a vent is opened on the surface of the sealing shell 102 for heat dissipation of the terminal device. The card holder 103 is used to connect the SMI card 104 to realize the wireless communication function of the terminal device. The network interface 105 is used to connect the crystal head 106 so that the terminal device can perform wired communication, which is convenient for data transmission and communication between the terminal device and the main station or other intelligent devices. The power module 107 is used to power various electrical equipment. The circuit board 108 integrates 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 communicate normally, the restart control module can control the terminal device to restart. At this time, the delay control module enters the timing state, so that the terminal device connects the circuit after a certain timing, so that the terminal device restarts. The above circuit connection is the prior art, and those skilled in the art are clearly aware of it and will not be elaborated here. When the terminal device cannot communicate normally after three restarts, the plug-in component 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, thereby solving communication failures caused by poor contact or looseness and improving the reliability of communication connections.

[0039] The plug-in assembly 200 is arranged in the mounting base 101, and includes a support base 201a fixed to the inner bottom wall of the mounting base 101, a movable shell 201b is slidably provided on the top of the support base 201a, a limit strip 201c is fixed at the bottom of the movable shell 201b, the limit strip 201c slides in the movable shell 201b, a movable base 201d slides in the movable shell 201b, a support plate 201e is fixed on one side of the movable shell 201b, a first spring 201f is fixed on one side of the support plate 201e, the other end of the first spring 201f is fixed to one side of the movable base 201d, a driving block 201g is fixed on the inner wall of the movable shell 201b, a driving groove 201d-1 is opened on one side of the movable base 201d, and the driving block 201g slides in the driving groove 201d-1.

[0040] The support base 201a is used to support the movable shell 201b. Through the setting of the limit bar 201c, the movable shell 201b can move stably on the top of the support base 201a. The movable base 201d is used to fixedly support the card base 103 and the network interface 105. Through the movement of the movable base 201d, the card base 103 and the network interface 105 can be driven to move synchronously. The support plate 201e is used to support the first spring 201f. The first spring 201f is in a compressed state and is used to push the movable base 201d. The driving block 201g is used to drive the movable base 201d to move and limit the position of the movable base 201d.

[0041] When the movable shell 201b moves away from the inner wall of the mounting base 101, the first spring 201f resets and stretches, and the movable 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 until the driving block 201g slides to the end of the driving groove 201d-1, and the movable base 201d can be pushed, so that the movable base 201d is away from the inner wall of the mounting base 101, thereby driving the card holder 103 and the network interface 105 to move.

[0042] Specifically, the plug-in assembly 200 also includes a driving member 202, which is arranged in the mounting base 101, including a fixing base 202a fixed to the bottom of the mounting base 101, a driving motor 202b is fixed on the top of the fixing base 202a, a driving disk 202c is fixed at the output end of the driving motor 202b, and a driving column 202d is fixed at the end of the driving disk 202c.

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

[0044] Specifically, the driving member 202 also includes a driving plate 202e fixed to one side of the movable shell 201b, and an arc groove 202e-1 and a straight groove 202e-2 are opened in the driving plate 202e, and the driving column 202d can slide in the arc groove 202e-1 and the straight groove 202e-2.

[0045] When the driving plate 202c rotates, the driving column 202d can slide from the arc groove 202e-1 to the straight groove 202e-2, and then slide from the straight groove 202e-2 to the arc groove 202e-1. The driving column 202d squeezes the inner walls of the arc groove 202e-1 and the straight groove 202e-2, 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 travel, the driving column 202d is in the arc groove 202e-1. At this time, since the arc groove 202e-1 and the drive disk 202c are concentric circles, the drive column 202d will not drive the drive plate 202e to move when it moves, so that the movable shell 201b stays in place during this period of time. The short stay time allows the static electricity on the SMI card 104 and the card holder 103 to have a chance 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 holder 103 to a certain extent.

[0046] Specifically, the plug-in assembly 200 also includes a positioning member 203, which is arranged in the mounting seat 101, including a support shell 203a fixed in the mounting seat 101, a positioning column 203b sliding in the support shell 203a, a pressure plate 203c fixed at the end of the positioning column 203b, a positioning groove 203c-1 is provided on one side of the pressure plate 203c, a chamfer 203c-2 is provided at the end of the pressure plate 203c, and a support frame 203d is also fixed in the mounting seat 101.

[0047] The support shell 203a is used to support the positioning column 203b, and the positioning column 203b is used to press down the pressure plate 203c, so that the pressure plate 203c squeezes the SMI card 104. Through the setting of the chamfer 203c-2, the SMI card 104 can be easily inserted into the card holder 103. The positioning groove 203c-1 is used to position the SMI card 104. The support frame 203d is used to support the bottom of the SMI card 104. Through the cooperation of the support frame 203d and the pressure plate 203c, the SMI card 104 can be positioned.

[0048] Specifically, the positioning member 203 further includes a second spring 203e whose end is fixed to the inner top wall of the supporting shell 203a, and a lifting ring 203f is fixed to the other end of the second spring 203e, and the lifting ring 203f is 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, an insert block 203g slides in the lifting ring 203f, a third spring 203h is provided in the insert block 203g, an extrusion block 203i is provided on one side of the insert block 203g, a slide groove 203a-1 and a slot 203a-2 are provided in the support shell 203a, the insert block 203g slides in the slide groove 203a-1, and the extrusion block 203i is inserted in the slot 203a-2.

[0051] By sliding the plug block 203g in the slide groove 203a-1, the angle of the lifting ring 203f is limited to prevent the lifting ring 203f from rotating. The third spring 203h is in a compressed state. When the movable shell 201b is away from the extrusion block 203i, the plug block 203g can push the extrusion block 203i. At this time, the plug block 203g can be inserted into the slot 203a-2 to limit the lifting ring 203f, so that the lifting ring 203f cannot move in the supporting shell 203a, thereby fixing the positioning column 203b and the pressure plate 203c, so that the pressure plate 203c and the support frame 203d can stably clamp the SMI card 104.

[0052] Example 2, reference Figure 2 , Figure 7 to Figure 9 , Fig.12 and Fig.13 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0053] Specifically, the plug-in assembly 200 also includes a removal piece 204, which is arranged in the mounting seat 101, including a support shaft 204a fixed in the mounting seat 101, a rocker rod 204b is rotatably connected to the surface of the support shaft 204a, a torsion spring is arranged between the support shaft 204a and the rocker rod 204b, and a button 204c is slidable in the mounting seat 101.

[0054] The support shaft 204a is used to support the rocker arm 204b, and the torsion spring arranged between the support shaft 204a and the rocker arm 204b is used to reset the rocker arm 204b. By pressing the button 204c, the button 204c can squeeze one end of the rocker arm 204b, so that the other end of the rocker arm 204b can move the SMI card 104, so that the SMI card 104 moves outward, thereby facilitating the removal of the SMI card 104.

[0055] Specifically, the plug-in assembly 200 also includes a clamping member 205, which is arranged in the mounting base 101, including a support frame 205a fixed in the mounting base 101, a card block 106-1 is arranged on the top of the crystal head 106, and a card slot 205a-1 is opened on the inner wall of the support frame 205a, and the card block 106-1 is connected to the card slot 205a-1.

[0056] The support frame 205a is used to support the crystal head 106. Both sides of the inner wall of the support frame 205a are in close contact with the surface of the crystal head 106. The crystal head 106 can be positioned by clamping the clamping block 106-1 in the clamping slot 205a-1.

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

[0058] The fourth spring 205e is in a stretched state. The reset tension of the fourth spring 205e allows the driving arm 205d to drive the cam 205c to rotate, so that the cam 205c squeezes 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.

[0059] Specifically, the clamping member 205 also includes a support rod 205g fixed in the mounting base 101, the surface of the support rod 205g is rotatably connected to a rotating base 205h, an adjusting rod 205i is hinged in the rotating base 205h, a connecting base 205j is fixed to one side of the driving arm 205d, another adjusting rod 205i is hinged to the surface of the connecting base 205j, the two adjusting rods 205i are hinged to each other, a fifth spring 205k is fixed to one side of the rotating base 205h, and the other end of the fifth spring 205k is fixed to one side of the connecting base 205j.

[0060] The support rod 205g is used to support the rotating seat 205h, and the rotating seat 205h is used to support the adjusting rod 205i. When the movable shell 201b is away from the adjusting rod 205i, the two adjusting rods 205i can be brought closer 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 squeezes the surface of the crystal head 106.

[0061] When the movable shell 201b approaches the adjusting rod 205i, the two adjusting rods 205i can be squeezed to make 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 squeezing of the crystal head 106 by the cam 205c.

[0062] During use, when the monitoring module detects that the communication module cannot communicate normally, the restart control module can control the terminal device to restart. At this time, the delay control module enters the timing state, so that the terminal device connects the circuit after a certain timing, so that the terminal device restarts. When the terminal device cannot communicate normally after three restarts, the drive motor 202b can be started, so that the output end of the drive motor 202b slowly rotates one circle.

[0063] During the rotation of the output end of the driving motor 202b, the driving disk 202c drives the driving column 202d to move in a circle, and the driving column 202d squeezes the inner walls of the arc groove 202e-1 and the straight groove 202e-2, so that the driving plate 202e drives the moving shell 201b to move, so that the moving shell 201b first moves away from the inner wall of the mounting seat 101. When the moving shell 201b moves away from the inner wall of the mounting seat 101, the first spring 201f resets and extends, and 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.

[0064] First, the shell 201b is moved away from the extrusion block 203i, and the plug block 203g can push the extrusion block 203i. At this time, the plug block 203g can be inserted into the slot 203a-2, and the lifting ring 203f can be limited, so that the lifting ring 203f cannot move in the supporting shell 203a, thereby fixing the positioning column 203b and the pressure plate 203c, so that the pressure plate 203c and the support frame 203d can stably clamp the SMI card 104.

[0065] At the same time, as the moving shell 201b moves, the moving shell 201b will move away from the two adjusting rods 205i, so that the two adjusting rods 205i can be 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 squeezes 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] As the movable shell 201b continues to move, the driving block 201g will slide to the end of the driving slot 201d-1, and the movable seat 201d can be pushed, so that the movable seat 201d is 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 movable shell 201b moves to the farthest end of its travel, the driving column 202d slides in the arc groove 202e-1. At this time, since the arc groove 202e-1 and the driving disk 202c are concentric circles, the driving column 202d will not drive the driving plate 202e to move when it moves, so that the movable shell 201b stays in place during this period of time. The short stay time allows the static electricity on the SMI card 104 and the card holder 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 holder 103 to a certain extent.

[0068] At this time, with the rotation of the driving disk 202c, the movable shell 201b will be reset, firstly making the card holder 103 and the network interface 105 re-cover the surface of the SMI card 104 and the crystal head 106; when the movable shell 201b is close to the adjusting rod 205i, the two adjusting rods 205i can be squeezed to make 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 squeezing of the crystal head 106 by the cam 205c.

[0069] When the moving shell 201b pushes the extrusion block 203i, the extrusion block 203i can push the insertion 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 invention rather than to limit it. Although the present invention 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 invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
