when the singlechip controls P1.0 to be 0 and the signal outputs of A1.0, A1.1, A1.2 and A1.3 to be 0000, the CD4514 No. ① connected with the interface P1.0 is gated, the interface of the plug X1-1 is at a high level, and the interfaces from the plug X1-2 to the plug X1-X96 are at a low level;
meanwhile, when the signal output of a1.4, a1.5, a1.6 and a1.7 is 0000 when the single chip microcomputer controls P2.0 to be 0, CD4067 No. ① connected to the interface P2.0 is gated, which indicates that the interface K (not shown) is connected to the interface Q1 of CD4067 No. ①, at this time, the plug X2-1 is low, and the plugs X2-2 to X2-X96 are high;

Example 2
As shown in fig. 1, 6 to 8, the fully automatic line inspection method of the present application includes the following steps:
s101: the control module converts any interface in the first detection interfaces of the first detection module from low level to high level, and other interfaces in the first detection interfaces are low level; meanwhile, the control module changes any interface of the second detection interface in the second detection module from high level to low level, and other interfaces in the second detection interface are high level.
In an embodiment, the control module controls the high and low level changes of the first detection interface and the second detection interface, and controls the communication state of the interface K in the second detection module and the interfaces Q1 to Q16 of the second detection interface.
In the embodiment, when any one of the first detection interfaces is at a high level, the other interfaces are at low levels; when any one of the second detection interfaces is at low level, the other interfaces are at high level.

In the embodiment, a plug of a first device to be tested is correspondingly connected with a first detection interface; and the plug of the second detection equipment is correspondingly connected with the second detection interface.
In the embodiment, the device to be tested is a 16-core plug device, and referring to fig. 3, the plugs X1-1 to X1-16 of the first device to be tested are distributed and correspondingly connected with the interfaces Y1 to Y16 of the first detection interface; the plugs X2-1 to X2-16 of the second device under test are correspondingly connected with the interfaces Q1 to Q16 of the second detection interface respectively.

In the embodiment, plug X1-1 sequentially tests the plugs in plug X2, and when a voltage is generated across the voltage measuring resistor R, it indicates that plug X1-1 is connected to the interface in plug X2.
For example, the plug X1-1 is connected with the plug X2-11, when the plug X1-1 detects the interface of the plug X2-11, the plug X1-1 and the plug X2-11 form a connection relation, the plug X1-1 and the plug X2-11 form a channel, current can be generated on the circuit, and the voltage can be generated on the voltage measuring resistor R when the current flows through the voltage measuring resistor R; when the plug X1-1 detects interfaces except the plug X2-11, the voltage measuring resistor R does not generate voltage
In the embodiment, each interface of the first detection interface is sequentially changed into high level, other interfaces are low level, and each interface performs scanning detection on an interface in the second detection interface; in this embodiment, the device under test is a 16-core plug device, that is, each interface of the first detection interface detects from the interface Q1 of the second detection interface to the interface Q16, so that each of the sixteen interfaces of the first detection interface scans and detects the second detection module 16 times, that is, the total detection is 16 × 16 — 256 times.
In the embodiment, after the plug of the plug X1 detects all the plugs of the plug X2, the control module records the detection result and can display the detection result through a computer; the display may be a table or a graph.

S104: and sequentially and repeatedly executing the first step to the fifth step on other interfaces in the first detection interface of the first detection module, and simultaneously sequentially and repeatedly executing the first step to the fifth step on other interfaces in the second detection interface of the second detection module until all the interfaces in the first detection interface completely detect all the interfaces in the second detection interface.
In the embodiment, when a certain plug of the plug X1 detects all plugs in the plug X2, the control module records the connection relationship; then, the other plugs in the plug X1 sequentially detect the plugs in the plug X2, and the control module records the connection relation;
since all the plugs in the plug X1 need to test the plug in the plug X2, after the plug X1-1 tests the interface in the plug X2, the other interfaces in the plug X1 continue to perform steps S101 to S105, and the plug X2 continues to repeat steps S101 to S105 until all the plugs in the plug X1 test all the plugs in the plug X2.
