Embodiment 1
[0064] refer to Figure 1~2 , providing a schematic diagram of the overall structure of an integrated access device, such as figure 1 , an integrated access device includes a box body 100, inside the box body 100 there is an accommodating space N1; a processing unit 200 is set in the accommodating space N1;
[0065] Specifically, the main structure of the present invention includes a box body 100, a processing unit 200, and an interface unit 300. Through the mutual cooperation between the box body 100, the processing unit 200, and the interface unit 300, it can be automatically switched once when testing the device under test. There are three modes of test, secondary test, and primary and secondary transmission test without rewiring. The degree of automation is high, which greatly improves the test efficiency, saves time and effort, and saves labor. Among them, the box 100 plays a role of protection and load The function of the processing unit 200 and the connection unit 300 ...
Embodiment 2
[0071] refer to Figure 12 , this embodiment is different from the first embodiment in that: the switching module 202 is divided into a binary output binary input mode 202a and a current voltage mode 202b, through the cooperation between the set binary output binary input mode 202a and the current voltage mode 202b, Fully considering the test requirements between the equipment to be tested and the measuring equipment, the practicability of the integrated access device is greatly improved. Specifically, the switch module 202 is divided into a switch mode 202a and a current-voltage mode 202b, and the switch-out mode 202a and the current-voltage mode 202b are respectively connected to the control signal module 205 .
[0072] Further, such as Figure 12 with 13 As shown, the current and voltage mode 202b includes an electromagnetic switching submodule 202b-1 and a small signal switching submodule 202b-2, and the electromagnetic switching submodule 202b-1 is connected to the smal...
Embodiment 3
[0081] refer to image 3 with Figure 30 This embodiment is different from the previous embodiment in that the connection unit 300 includes a connecting piece 301 to be tested, an indicator light 302, a communication interface 303, a control button 304, a small signal voltage and current interface 305, an electromagnetic voltage interface 306, a magnetic Type current interface 307, acquisition interface 308 and input and output interface 309, the connection piece 301 to be tested, the indicator light 302, the communication interface 303, the control button 304, the small signal voltage and current interface 305, the electromagnetic voltage interface 306, The magnetic current interface 307, the acquisition interface 308 and the input and output interface 309 provide conditions for the connection of the equipment under test and the test equipment, and the operation is simple, convenient and fast, and no operator is required to connect them one by one. Specifically, the connecti...
