Buffer is connected with from controller.
The utility model includes host and slave two parts, and host is mainly responsible for periodically serial send respectively to school cable
Identification information is to slave, and slave is responsible for receiving and display host is transmitted through the identification information to school cable come.Identification information can be adopted
With the title or number to school cable.Host and slave are located at the both ends to school cable when to line, one end to school cable
To in line interface, host sends the identification information to school cable by master on access host, can be shown on slave screen currently with from
Machine to line interface be connected the identification information to school cable.
The master controller of the utility model uses the single-chip microcontroller of STM32 framework, shows, at key for being responsible for main display
The work such as reason, indicator light control and data transmission and reception.Key and main display are respectively used to scene editor and display is every
Item waits for the identification information of school cable (corresponding each master to line interface), such as the title or number of cable, also into compiled
Good cable title.The utility model not only have the advantages that school line it is accurate, rapidly, can one man operation compared with multimeter it is excellent
Gesture is to input and show the title or number to school cable, rather than simple on-off prompts.

Failure, and can show the serial number of all short-circuit cables, it is convenient for the timely unshorting failure of related personnel.As shown in figure 3, short-circuit
Testing process is as follows:
OUT1 first exports high level, and triode 1 is connected, and is low level, the low electricity of other mouthfuls of latch outputs on cable 1
Flat, triode ends, and is high level on cable 2-128.If there is no short trouble, master control between cable 1 and 2-128 cable
Device processed is all high level other than In1 by inputting the data that buffering receives.It is assumed that have short trouble between cable 1 and 2,
Then In2 can be by OUT1 down for low level, therefore can determine whether that there are short troubles between cable 1 and 2；It similarly may determine that cable
1 and other cables whether there is also short troubles.
According to above-mentioned steps, the level for the Out127 that successively drags down Out2, Out3 ... be can detecte out complete between cable
Portion's short trouble.This method also can reliably detect 100 Europe transition resistances between cable.
