[0016] This invention provides an IoT smart DTU terminal, such as... Figure 1-5 As shown, the system includes a housing 1, several monitoring connectors 2, and a battery, main circuit board, debugging module, display screen 3, and antenna 4 housed within the housing 1. The monitoring connectors 2 are connected to the debugging module and include FTU monitoring connectors, DTU monitoring connectors, TTU monitoring connectors, network communication monitoring connectors, and distribution master station monitoring connectors. All of these connectors are connected to the debugging module, which is a commercially available product. The debugging module is electrically connected to the main circuit board, which is electrically connected to the battery. The display screen 3 is also electrically connected to the main circuit board. In use, the FTU, DTU, TTU, network communication, and distribution master station monitoring connectors can be used to test various parts of the power distribution automation system. After testing and debugging by the debugging module, various data are obtained and displayed on the display screen 3.

[0017] The top of the case 1 is equipped with a handle 8 for easy carrying.

[0018] Antenna 4 is used to receive signals. The housing 1 has a through hole 5 for antenna 4 to extend out. To protect antenna 4, it can be retracted into housing 1 when not in use. When needed, antenna 4 can be extended out of through hole 5 via telescopic mechanism 7. Housing 1 is equipped with a three-degree-of-freedom adjustment mechanism 6 and a telescopic mechanism 7. The telescopic mechanism 7 is used to drive antenna 4 to extend out of through hole 5, and the three-degree-of-freedom adjustment mechanism 6 is used to drive antenna 4 to swing in different directions and angles.

[0019] After the antenna 4 extends out of the through hole 5, in order to optimize the signal reception capability of the antenna 4, the angle of the antenna 4 is continuously changed by the three-degree-of-freedom adjustment mechanism 6 to increase the signal reception capability of the antenna 4 and avoid affecting the use of the DTU terminal.

[0020] like Figure 3 As shown, the three-degree-of-freedom adjustment mechanism 6 includes a support plate 9, gear 1 61, gear 2 62, gear 3 63, rotating shaft 1 64, rotating shaft 2 65, rotating shaft 3 66, support plate 69, and three sets of connecting rods 1 67 and 2 68.

[0021] Gear 1 61 is pivotally connected to support plate 9 via bearings. Gear 2 62 is pivotally connected to the center of gear 1 61 via bearings, with the center of the bearings being through holes. Gear 3 63 is pivotally connected to gear 2 62 via bearings, with the center of the bearings also being through holes. The three gears are rotatably connected by bearings, allowing gears 1 61, 2 62, and 3 63 to rotate independently.

[0022] Both rotating shaft 2 65 and rotating shaft 3 66 are hollow tubes. Rotating shaft 3 66 is fixedly installed at the center of gear 3 63. Rotating shaft 2 65 is fixedly installed at the center of gear 2 62 and passes upward through rotating shaft 3 66. There is no contact between rotating shaft 2 65 and rotating shaft 3 66. Rotating shaft 1 64 is fixedly installed at the center of gear 1 61 and passes upward through the inner cavity of rotating shaft 2 65. There is no contact between rotating shaft 1 64 and rotating shaft 2 65.

[0023] like Figure 3 As shown, pivot 64, pivot 65, and pivot 66 are hinged to support plate 69 via connecting rod 67 and connecting rod 68, respectively. Connecting rod 67 and connecting rod 68 are both L-shaped. Specifically, the horizontal sections of the three connecting rods 67 are fixed to pivot 64, pivot 65, and pivot 66, respectively, while the vertical sections are hinged to the horizontal sections of connecting rod 68. The other end of connecting rod 68 is hinged to support plate 69.

[0024] When one of the gears drives the shaft to rotate, the shaft will drive the support plate 69 to rotate at a certain angle through connecting rod 67 and connecting rod 68. The three sets of gears can drive the antenna 4 on the support plate 69 to rotate at different angles.

[0025] In this embodiment, three sets of connecting rods 67 and 68, as well as gears and shafts, are used. The three sets of connecting rods 67 and 68 are distributed at equal angles around the center of the support plate 69, and the support plate 9 is provided with three sets of drive components that individually drive gears 61, 62, and 63.

[0026] like Figure 3 As shown, the drive assembly includes drive gears 10 and drive motors 11. Drive motor 11 is fixed to the support plate 9, and drive gears 10 are coaxially mounted on the output shaft of drive motor 11. Three sets of drive gears 10 mesh with gear one 61, gear two 62, and gear three 63, respectively. By independently driving gear one 61, gear two 62, and gear three 63 through the three sets of drive motors 11, the antenna 4 on the support plate 69 can swing in different directions. The three sets of drive motors 11 can be sequentially controlled to start and stop cyclically via a PLC.

[0027] like Figure 1 As shown, the telescopic mechanism 7 includes a lead screw 71, a slide rod 72, a nut sleeve 74 threaded onto the lead screw 71, a sliding sleeve slidably mounted on the slide rod 72, and a servo motor 75. Both ends of the slide rod 72 are mounted inside the housing 1 via fixed seats. Both ends of the lead screw 71 are fixed inside the housing 1 via bearing seats 73. The servo motor 75 is mounted inside the housing 1, and its output shaft is coaxially connected to the lead screw 71. Both the nut sleeve 74 and the sliding sleeve are connected to the support plate 9. The servo motor 75 controls the antenna 4 to extend out of and retract into the housing 1.
