[0071] Please see Figure 1-14 This invention provides a wireless data communication terminal device for a power system, used to access the power system for wireless data communication, realize digital and intelligent management, and implement various wireless communication interaction methods, such as 5G, 4G, WiFi, local area network, etc.

[0072] include:

[0073] Terminal 1, with a frame 3 at its bottom that can fix terminal 1 in a flat position;

[0074] Support foot 2 is located at the bottom of terminal 1 to provide support for the bottom of terminal 1;

[0075] Terminal 1 contains:

[0076] Antenna assembly 21 is installed on the top of terminal 1. Antenna assembly 21 has two states: extended and retracted. A heat dissipation module 28 is installed inside terminal 1. The opening and closing of the air inlet of heat dissipation module 28 is controlled by the extended and retracted state of antenna assembly 21.

[0077] A wireless communication module 25 is located inside and connected to the terminal 1. A controller 24 is provided on the outside of the wireless communication module. The controller 24 is connected to the terminal 1 and extends to the outside of the terminal 1. A data interface module 26 is provided on the end of the terminal 1 away from the controller 24. The data interface module 26 is connected to the terminal 1 and extends to the outside of the terminal 1.

[0078] The commutation structure 22 connects to the antenna assembly 21 and forms a limit on the antenna assembly 21. The commutation structure 22 has two states: limit and disengagement. In the limit state, the movement of the antenna element 211 is restricted. In the disengagement state, the antenna assembly 21 can be commutated.

[0079] The drive unit 23 is connected to the terminal 1 and configured to rotate the antenna assembly 21 about the central axis of the antenna assembly 21.

[0080] In this embodiment, the antenna assembly 21 extends to the outside of the terminal 1 in two rows. Each row of antenna assembly 21 can move independently. The upper part of the antenna assembly 21 can be tilted or horizontal relative to the upper surface of the terminal 1. When tilted, the upper parts of the two antenna assemblies 21 can tilt at the same angle or at different angles. When tilted at the same angle, the upper parts are in the same plane.

[0081] In one embodiment, antenna assembly 21 includes:

[0082] Telescopic rod 212 extends outward from the upper surface of terminal 1. The telescopic rod 212 has a multi-section structure and its length can be adjusted when it is extended or retracted. A placement plate 217 is provided at one end of the telescopic rod 212 that extends outward, and the placement plate 217 is hinged to the telescopic rod 212.

[0083] Antenna element 211 is embedded inside placement plate 217. Antenna element 211 extends into terminal 1 from the hinge position of placement plate 217 and telescopic rod 212 and is equipped with feed line 213. The two ends of feed line 213 are respectively connected to antenna element 211 and wireless communication module 25.

[0084] Storage slot 216 is formed on the surface of reversing structure 22, and placement plate 217 is folded and stored inside storage slot 216.

[0085] In this embodiment, the telescopic rod 212 is telescopic, which allows the placement plate 217 located at the telescopic end of the telescopic rod 212 to move up and down. The two rows of placement plates 217 can move independently, that is, the telescopic height of each row is uniform. In use, the upper surface of the placement plate 217 can be in the same plane according to the position of the placement plate 217, and the signal amplification can be guaranteed whether it is tilted or horizontal.

[0086] The telescopic rod 212 extends outward from the upper surface of the terminal 1 and is connected to the reversing structure 22. The telescopic rod 212 can swing relative to the reversing structure 22. When the telescopic rod 212 retracts and swings so that one of the planes passing through the axis of the telescopic rod 212 is parallel to the upper surface of the terminal 1, the placement plate 217 can retract into the storage slot 216.

[0087] In one embodiment, antenna assembly 21 further includes:

[0088] Matching network 214, located in feed line 213, is a circuit used to improve impedance matching between antenna element 211 and wireless communication module 25.

[0089] Directional controller 215, located inside and connected to terminal 1, is used to change the radiation or reception directionality of antenna element 211.

[0090] In this embodiment, a matching network 214 is used to improve signal transmission efficiency and reduce VSWR and reflection coefficient. For example, the matching network 214 can be a transformer, filter, or tuner. A directional device 215 is used to increase antenna gain and reduce interference and noise. For example, the directional device 215 can be a reflector or lens.

[0091] In one embodiment, the commutation structure 22 includes:

[0092] The moving disk 221 is circular, and its axis is located at the central axis of the antenna assembly 21 and connected to the terminal 1. Both ends of the moving disk 221 extend to the inner and outer sides of the terminal 1. A mounting bracket 222 is provided on the upper part of the moving disk 221, and the antenna assembly 21 is installed on the inner side of the mounting bracket 222 and extends into the interior of the terminal 1.

[0093] A cavity 224 is formed inside the telescopic rod 212. A limiting head 225 and a pressing plate 226 are provided inside the cavity 224. The pressing plate 226 and the limiting head 225 are located at both ends of the cavity 224, respectively. An electromagnet 227 is provided on the outside of the pressing plate 226 to control the position of the pressing plate 226.

[0094] In this embodiment, one end of the telescopic rod 212 is installed inside the mounting bracket 222, and a cylindrical protrusion extends from the outer side of the telescopic rod 212. The cylindrical protrusion restricts the telescopic rod 212, allowing it to swing only around the axis of the cylindrical protrusion. The limiting head 225 can limit the insertion of the placement plate 217. When the electromagnet 227 pushes the extrusion plate 226 to move by attraction, the extrusion plate 226 will extrude the cavity 224. The medium filled inside the cavity 224 can push the limiting head 225 to move outward, thus limiting the placement plate 217.

[0095] The contact position between the placement plate 217 and the limiting head 225 is adapted to the shape of the end of the limiting head 225 near the placement plate 217. The limiting head 225 can be inserted into the placement plate 217. The electromagnet 227 is fixed inside the telescopic rod 212, and the pressing plate 226 is magnetic. When the electromagnet 227 is energized, it can magnetically attract or repel the pressing plate 226.

[0096] In one embodiment, the commutation structure 22 further includes:

[0097] The ball bearing 223 is disposed between the motion disk 221 and the terminal 1 to reduce the friction of the motion disk 221 during rotation.

[0098] Magnetic plates 228 are fixed to the inner sides of the mounting bracket 222 and the moving plate 221 respectively, and the magnetic plates 228 are perpendicular to each other after being extended. The magnetic plates 228 are located on both sides of the swing of the telescopic rod 212, and the swing amplitude of the telescopic rod 212 is 90°.

[0099] In this embodiment, in order to enable the antenna to amplify the signal in different ranges, the commutation component is set to be rotatable. The ball bearing 223 between the moving disk 221 and the terminal 1 can reduce the friction between the moving disk 221 and the terminal 1 during rotation, thereby ensuring the service life of the moving disk 221. The rotation range of the moving disk 221 is 180°, and the internal connecting wires are all provided with stretchable length, so that the connecting wires will not be affected within the rotation range of the moving disk 221.

[0100] In one embodiment, the driving device 23 includes:

[0101] The push plate 235 is slidably installed on the inner side of the telescopic rod 212. A positioning plate 236 is provided on the outer side of the push plate 235. Hinges 237 are provided on both sides of the positioning plate 236 to form hinges to the placement plate 217 and the push plate 235 respectively.

[0102] The chamber 232 is fixed inside the moving plate 221. One end of the chamber 232 is provided with a connecting pipe 233, which passes through the moving plate 221 and extends into the telescopic rod 212. The other end of the chamber 232 is provided with a push rod 231, which forms a compression on the chamber 232.

[0103] The drive motor 234 is located inside the terminal 1 and connected to the terminal 1. The output end of the drive motor 234 is connected to the motion disk 221 and drives the motion disk 221 to rotate.

[0104] In this embodiment, the interiors of chamber 232, connecting pipe 233, and telescopic rod 212 are all filled with a medium, and the interior of cavity 224 is also filled with a medium. The telescopic rod 212 contains two independent chambers 232, which are controlled by different push rods 231. The push rods 231 are electric push rods 231. When the push rods 231 extend, they compress the chamber 232, and the cavity 224 increases, causing the push plate 235 to move. Thus, the positioning plate 236 is used to control the swing angle of the placement plate 217.

[0105] Among them, the connecting pipe 233 is a flexible hose. After the telescopic rod 212 is swung and laid down, one end of the flexible hose is bent and squeezed, and the flow orifice becomes smaller. When the push rod 231 pushes to pressurize the inside of the chamber 232, the pressure inside the flexible hose is relatively large, which will gradually cause the telescopic rod 212 to detach from the magnetic plate 228 and swing, thereby cooperating with the other magnetic plate 228 to make the telescopic rod 212 stand upright.

[0106] In one embodiment, the heat dissipation module 28 includes:

[0107] The heat dissipation hole 281 extends from the storage slot 216 into the terminal 1. A dust cover 282 for dust prevention is provided on its inner side. A fan 283 is provided inside the terminal 1. The air inlet of the fan 283 is the heat dissipation hole 281, and the air outlet is opened on one side of the fan 283.

[0108] In this embodiment, the fan 283 is used to dissipate heat inside the terminal 1. When in use, the placement plate 217 is opened to open the air inlet. After the placement plate 217 is closed, the heat dissipation hole 281 is sealed, so the heat dissipation hole 281 can be opened and closed by the placement plate 217.

[0109] In one embodiment, the heat dissipation module 28 further includes:

[0110] A sealing plate 285 is located inside the moving plate 221. A pressure ring 284 is provided on its outer side. The pressure ring 284 passes through the moving plate 221 and extends to the outer side of the moving plate 221. A return spring 286 is provided between the pressure ring 284 and the moving plate 221 to push the pressure ring 284 to the outside.

[0111] The U-shaped cavity 287 is located at the bottom of the sealing plate 285 and the pressure ring 284, with the sealing plate 285 and the pressure ring 284 respectively inserted into both ends of the U-shaped cavity 287.

[0112] In this embodiment, when the placement plate 217 is closed, it will squeeze the pressure ring 284, allowing the pressure ring 284 to move downward. Due to the presence of the medium inside the U-shaped cavity 287, the downward pressure of the pressure ring 284 will squeeze the medium inside the U-shaped cavity 287, thus pushing the other side of the U-shaped cavity 287 to move upward. After moving a certain distance, the sealing plate 285 bends and fits against the inner wall of the heat dissipation hole 281. Therefore, the air inside the heat dissipation hole 281 will be pushed upward from the bottom of the heat dissipation hole 281, thereby blowing the dust on the upper part of the dust cover 282 in the opposite direction and reducing the dust residue.

[0113] When the placement plate 217 is opened, the upper restraint of the pressure ring 284 is released, and then rises under the action of the return spring 286, thereby causing the sealing plate 285 to move down and the heat dissipation hole 281 to open.

[0114] The present invention also provides a Web terminal operation method for a wireless data communication terminal device, used to operate the aforementioned wireless data communication terminal device in the power system, comprising the following steps:

[0115] S1. Enter the address of the wireless data communication terminal device on the web interface and log in to the device account;

[0116] S2. Control the wireless data communication terminal device according to the different functions provided by the Web terminal, and adjust the antenna swing position according to different data transmissions;

[0117] S3. The Web terminal packages the operation information contained in the different operation commands triggered and sends it to the server. The server then forwards the package to the wireless communication module 25. The wireless communication module 25 unpacks the received operation commands and operation information and controls the antenna assembly 21, commutation structure 22 and drive device 23 to achieve antenna amplification based on the commands contained in the operation information.

[0118] After the antenna assembly 21, commutation structure 22 and drive device 23 complete their actions, the action position data of the antenna assembly 21, commutation structure 22 and drive device 23 are packaged and sent to the data terminal.

[0119] In one embodiment, the operation instructions sent by the Web terminal include control of the angle of the antenna assembly 21, control of the commutation position of the commutation structure 22, control of the driving angle of the driving device 23, and control of the height of the antenna assembly 21.

[0120] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

[0121] 1. This invention adjusts the angle and position of the antenna inside the communication terminal device to achieve antenna gain within a certain range, thereby obtaining a more stable data transmission effect during the main data interaction process, improving transmission efficiency and ensuring stable data interaction.

[0122] 2. Among them, the higher the antenna gain, the better the directivity, the more concentrated the energy, and the narrower the beam. The higher the gain and the longer the antenna length, the more the antenna can be adjusted to different positions to perform different wireless data interactions. Under different wireless data interaction methods, it can ensure stable interaction effects.

[0123] 3. The present invention provides two rows of antenna components 21 that can be adjusted separately. In use, the tilt angle and top surface of the two rows of antenna components 21 are located in the same plane, thereby ensuring antenna gain. The antenna is set to be rotatable, so that it can be oriented to different angle positions and perform different data interaction methods.

[0124] 4. In this invention, the position for fitting the antenna assembly 21 is set as a heat dissipation hole 281. When in use, the antenna assembly 21 is raised, thereby opening the heat dissipation hole 281 to facilitate heat dissipation during operation. When the antenna assembly 21 is retracted, the position of the heat dissipation hole 281 can be cleaned according to the position of the antenna assembly 21 to avoid dust accumulation.

[0125] Although the present invention has been disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the appended claims.
