Each pin of device can be connected to a decoder.
Further, each input detection I/O port of the governor circuit be connected to it is a piece of select decoder, it is and each
Piece selects each pin of decoder to may connect to a decoder, and each pin of the decoder can be connected to one
Decoder.
Using the Wiring detection method of above-mentioned wiring detection circuit, comprise the following steps：
S1 determines the quantity of decoder, each output detection IO of governor circuit according to the quantity of outlet terminal to be detected
Mouth is connected to a decoder, and each pin of each decoder can connect a decoder, the decoder it is every
Individual pin can also connect a decoder, and so on, make the I/O port of each decoder be all connected with an output connection to be detected
End；Until all outlet terminals to be detected are all connected to a decoder；
S2 determines the quantity of decoder, each input detection IO of governor circuit according to the quantity of input terminal to be detected
Mouth is connected to a decoder, and each pin of each decoder can connect a decoder, the decoder it is every
Individual pin can also connect a decoder, and so on, make the I/O port of each decoder be all connected with an input wires to be detected
End；Until all input terminals to be detected are all connected to a decoder；
The coding of each corresponding the connected decoders of outlet terminal to be detected of S3, governor circuit by the coding to
Corresponding outlet terminal to be detected sends detection signal；
The coding of corresponding the connected decoder of each input terminal to be detected of S4, governor circuit scan each
The pin of decoder, and record the coding for the pin for having frequency variation signal, you can detect which input terminal to be detected with connecing
The outlet terminal to be detected connection of detection signal is received, and is contrasted with default standard annexation, show that current wiring is
No correct conclusion.
The beneficial effects of the present invention are：The IO of governor circuit produces the signal of scanning by decoder, can be easily
The output detection Wiring port of any number is expanded to, and conveniently realizes the detection of any input detection Wiring port, from
And conveniently realize the detection of corresponding terminals.
