Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a multi-scenario detection device for terminal network access. Background Technology

[0002] With the increasing population, electricity consumption is also rising continuously. The safety of power grid operation determines the stability of people's electricity use. During the operation of the power grid, it is necessary to purchase smart terminals frequently to assist in the stable operation of the power grid. However, when smart terminals are connected to the power grid, they need to undergo strict grid access testing. Current testing devices can generally only test one or a few simple test items, which is not comprehensive enough. Furthermore, they do not introduce electromagnetic disturbance detection mechanisms and ignore the usage status of smart terminals in real environments such as harmonic interference from high-voltage transmission lines and radio frequency radiation from industrial wireless equipment. They cannot fully reflect the actual operating performance of the equipment, which not only increases the operation and maintenance costs of the power grid, but also poses a potential threat to the reliability and security of the smart grid.

[0024] After placing the smart terminal to be tested for network access on one side of the main body 1 of the device, connect the smart terminal to the testing interface 6 to achieve the connection between the main body 1 of the device and the smart terminal. Then, different testing scenarios can be selected through the interactive screen 2. The main control unit 4 can drive the controllable power module 5 to provide different testing scenarios.

The data processing unit 16 can integrate and process the data collected by the sensor group 3 and identify abnormal situations. The storage unit 17 can be used to store the detection data. The detection report processed by the data processing unit 16 can be sent to the interactive screen 2 for visualization. The parameters and scenarios selected by the operator through the interactive screen 2 can be fed back to the central processing unit 14, which then drives the corresponding modules and electrical components to work.

[0028] Preferably, the device also includes a communication module 18, which is disposed inside the main body 1. The outer wall of the main body 1 is provided with a communication interface 19 for terminal connection.

[0030] Preferably, the disturbance application mechanism further includes a base plate 20, which is disposed on the side wall of the device body 1 and located below the moving path of the rotating rod 9.

[0031] The base plate 20 allows operators to place the terminal, ensuring that the terminal is located below the moving path of the rotating rod 9, so that electromagnetic interference can be applied accurately.

[0032] Preferably, the disturbance application mechanism further includes an electric turntable 21 and a placement plate 22. The electric turntable 21 is mounted on the base plate 20, and its rotation surface is connected to the bottom surface of the placement plate 22. The placement plate 22 is for placing the terminal and is located above the movement path of the rotating rod 9. The central processing unit 14 is electrically connected to the electric turntable 21.

[0033] During the application of radio frequency electromagnetic interference, the electric turntable 21 can drive the terminal to rotate slightly through the placement plate 22 to change the angle of radio frequency electromagnetic interference in order to simulate different electromagnetic interference scenarios.

[0035] To ensure the accuracy of the test, a clamping mechanism is provided on the placement plate 22. When the bottom end of the terminal is placed in front of the fixed slot 23, the clamping plate 24 is pulled to move in the opposite direction, so that the spring 25 is compressed. When the terminal is placed into the fixed slot 23, the clamping plate 24 can be released. Under the action of the spring 25, the clamping plate 24 can clamp and fix the terminal.

[0036] Preferably, the disturbance application mechanism further includes a protective cover 26, which is disposed on the top surface of the device body 1 and covers the electric slide 7, the rotary motor 8 and the rotating rod 9 inside. The side wall of the protective cover 26 is open. The disturbance application mechanism also includes an opening door 27, the top surface of which is connected to the open side of the protective cover 26 via a hinge 28.

[0037] The protective cover 26 can protect the electric slide 7, rotary motor 8 and transmitting antenna 12 from dust and rainwater corrosion. When disturbance is required, the electric slide 7 drives the rotary motor 8 to rotate the rod 9. The end of the rotating rod 9 can push the opening door 27 to rotate outward. After the test is completed, the rotating rod 9 can move back into the protective cover 26. Under the action of gravity, the opening door 27 rotates downward around the hinge 28 as the axis, thereby closing the side wall of the protective cover 26 and protecting the inside of the protective cover 26.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
