Inbound port, described main circuit uses and interlocks step by step, when L1 powers, even if L2, L3 are simultaneously
Power supply, system still only with L1 as power supply, in order to avoid the short circuit caused because of wrong line etc.
Fault, is provided out 220V alternating current power supply at described relay main contact parallel connection, it is simple to outside
Using, described signal processing circuit is assisted electricity to form by single-chip microcomputer and relay, described main circuit
In also comprise fuse, described AC-DC change-over circuit is that single-chip microcomputer and other control systems provide
DC source；Described main circuit is made up of the above power supply circuits of at least two-way, described main circuit by
Single-phase multichannel or three-phase multiplex circuit composition, a kind of self adaptation multiple feed monitoring side, tunnel
Method, described monitoring method process is as follows: whether power supply circuits are powered and controlled relay switch, dress
Putting offer direct current and alternating current power supply, single-chip microcomputer receives line state signal, and output corresponding states is anti-
Feedback signal, described each power supply circuits control corresponding relay.
As described in Figure 1, it is respectively provided with L1, L2, L3 three-line, as a example by 3 circuits,
The present invention is specifically described.
Embodiment one
When 3 circuits are not powered, the equal attonity of KA1, KA2, KA3, device non-transformer
Output, no signal exports.
Embodiment two
When only L1 powers, the normally opened adhesive of KA1, normally closed disconnection, KA2, KA3 attonity,
Device provides direct current and alternating current power supply, and single-chip microcomputer is in running order, and now, P1.1 inputs
Being 1, P1.2, P1.3 input is 0, corresponding output state feedback signal.
Embodiment three
When only L2 powers, the normally opened adhesive of KA2, normally closed disconnection, KA1, KA3 attonity,
Device provides direct current and alternating current power supply, and single-chip microcomputer is in running order, and now, P1.2 inputs
Being 1, P1.2, P1.3 input is 0, corresponding output state feedback signal.
Embodiment four
When only L3 powers, the normally opened adhesive of KA3, normally closed disconnection, KA1, KA2 attonity,
Device provides direct current and alternating current power supply, and single-chip microcomputer is in running order, and now, P1.3 inputs
Being 1, P1.1, P1.2 input is 0, corresponding output state feedback signal.
Embodiment five
