DETAILED DESCRIPTION

[0019] The principles and features of the present invention are described below with reference to the accompanying drawings. The enumerated embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] Reference Figure 1 and Figure 2 The present invention provides a distribution automation terminal detection device, which includes an operating console 17, a distribution terminal 1, a communication module, a simulation module, a detection module, an early warning module and a mobile mechanism. The simulation module includes an analog circuit breaker 2 and an analog signal transmitter 3 arranged on the operating console 17 and electrically connected to the distribution terminal 1 respectively. The detection module includes an interface simulator 4 and a state quantity collector 5 arranged on the operating console 17 and electrically connected to the distribution terminal 1 respectively. The early warning module includes a call device and an information transceiver device, and the call device and the information transceiver device establish a communication connection with the distribution terminal 1 through the communication module. The mobile mechanism includes a first electric telescopic rod 6 and a display screen 7 respectively electrically connected to the distribution terminal 1. The fixed end of the first electric telescopic rod 6 is set on the operating console 17, and the movable end of the first electric telescopic rod 6 is electrically connected to the display screen 7.

[0021] For example, the simulated circuit breaker 2 provided on the operating console 17 is electrically connected to the power distribution terminal 1 to simulate the switch opening, energy storage and pressure loss state of the power distribution terminal 1, and the simulated signal transmitter 3 electrically connected to the power distribution terminal 1 can also be used to simulate the electrical signals of the switch opening, energy storage and pressure loss state of the power distribution terminal 1. In the process of simulating the switch opening, energy storage and pressure loss state of the power distribution terminal 1, the interface simulator 4 can be used to simulate the interface of the simulated circuit breaker 2 of different specifications from different manufacturers, and the state quantity collector 5 collects the electrical signal emitted by the simulated signal transmitter 3 in real time and compares it with the electrical signal threshold set by the power distribution terminal 1 to determine whether the power distribution terminal 1 is abnormal. When the state quantity collector 5 When the electrical signal collected exceeds or is lower than the electrical signal threshold, it indicates that the power distribution terminal 1 has an abnormality. For the abnormal power distribution terminal 1, the abnormal electrical signal of the power distribution terminal 1 can be transmitted to the external call equipment and information receiving and sending equipment through the communication module. In particular, in order to enable employees to carefully observe the data collected by the state quantity collector 5 in real time, the power distribution terminal 1 can send a signal instruction to the first electric telescopic rod 6 set on the operating table 17, so that the moving end of the first electric telescopic rod 6 drives the display screen 7 to move upward, thereby facilitating the employees to carefully observe the electrical signal data of the power distribution terminal 1 collected by the state quantity collector 5, and the display screen 7 can display the electrical signal data collected by the state quantity collector 5 in real time.

[0022] The operating table 17 is provided with a wire arrangement mechanism, which includes a first cavity 19 and a second cavity 18 . The first cavity 19 is used to place a test circuit 20 , and the second cavity 18 is used to place a test wire.

[0023] For example, in order to ensure the safety of employees, the test circuit 20 and the test line can be placed in the first cavity 19 and the second cavity 18 for separate management to avoid safety accidents such as short circuits. The test circuit 20 can meet the different analog circuits of the distribution terminal 1, and the test line is used to connect analog circuit breakers 2 of different specifications from different manufacturers to the distribution terminal 1.

[0024] This embodiment includes an encryption device 8, which is used to perform gateway authentication and data encryption when the power distribution terminal 1 performs data communication with the communication device and the information transceiver device.

[0025] For example, in order to ensure the data security of the distribution terminal 1, the encryption device 8 is used to perform gateway authentication and data encryption when the distribution terminal 1 communicates data with the call equipment and information transceiver equipment. The gateway authentication adopts the grid standard gateway authentication protocol standard and grid encryption algorithm to encrypt the data.

[0026] The fingerprint recognition device 13 is provided on the operating console 17 and is electrically connected to the power distribution terminal 1 .

[0028] The early warning module further includes an audible and visual indicator 14 and an infrared sensor 15 electrically connected to the power distribution terminal 1 , respectively. The audible and visual indicator 14 and the infrared sensor 15 are both arranged on an operating console 17 .

[0029] For example, to ensure the safety of the equipment on the operating table 17 , when the infrared sensor 15 detects that an object is approaching the operating table 17 , the sound and light indicator 14 issues a sound warning, and the employee can stop the sound and light warning of the sound and light indicator 14 through recognition by the fingerprint recognition device 13 .

[0030] The detection module further includes a voltage transformer 9 and a current transformer 10 electrically connected to the power distribution terminal 1 . The voltage transformer 9 and the current transformer 10 are both disposed in the second cavity 18 .

[0031] For example, in order to ensure the safety of the employees' detection, the employees can set the voltage transformer 9 and the current transformer 10 on the test line to detect whether the test line has a safety accident problem of leakage.

[0032] This embodiment includes an abnormality saving module, which includes local storage and cloud storage. The local storage includes a solid-state hard disk 11 electrically connected to the distribution terminal 1, and the cloud storage includes a cloud service storage that establishes a communication connection with the distribution terminal 1 through a communication module.

[0033] For example, when the electrical signal collected by the state quantity collector 5 exceeds or is lower than the electrical signal threshold, it indicates that an abnormality has occurred in the power distribution terminal 1. At this time, the electrical signal data can be quickly stored locally through the solid-state hard disk 11 in the abnormality storage module. In order to ensure the security of the electrical signal, the electrical signal data can be backed up to the cloud service storage through cloud storage.

[0034] This embodiment includes a control switch mechanism, which includes a knife switch 16 and a second electric telescopic rod 12. The knife switch 16 is arranged in series on the test circuit 20.

The fixed end of the second electric telescopic rod 12 is arranged on the side wall of the first cavity 19, and the movable end of the second electric telescopic rod 12 is connected to the knife of the knife switch 16.

[0035] For example, when the voltage transformer 9 and the current transformer 10 detect a safety accident problem of leakage in the test line, a signal instruction can be sent to the second electric telescopic rod 12 through the distribution terminal 1, so that the moving end of the second electric telescopic rod 12 pushes the knife switch 16 to open, thereby disconnecting the electrical connection between the test circuit 20 and the distribution terminal 1.
