Compared with prior art, the utility model has the advantage of, provide DC power supply by AC-DC change-over circuit, the power supply that transformer regulating relay sends gives outside use, is collected by signal processing circuit, is sent signal, carries out controlling and monitors.
Accompanying drawing explanation
Fig. 1 is the explanation circuit diagram of a kind of tunnel of the utility model self adaptation multiple feed device and monitoring method.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
A kind of tunnel self adaptation multiple feed device, comprises main circuit, and described main circuit comprises relay, transformer, AC-DC change-over circuit and gathers circuit on-off information and the signal processing circuit of the relevant monitor signal of output; The coils from parallel connection of coils of described relay is in corresponding line, and described relay main contact one end connects corresponding line, and described transformer is delivered in one end parallel connection; Auxiliary contact one end of described relay is connected with the DC power supply after conversion, one end connects described single-chip microcomputer input port, described main circuit adopts and interlocks step by step, in order to avoid the short trouble caused because of wrong line etc., described relay main contact parallel connection place outwards provides 220V AC power, be convenient to outside use, described signal processing circuit is made up of single-chip microcomputer and relay auxiliary electrical, and described AC-DC change-over circuit provides DC power supply for single-chip microcomputer and other control systems.
As described in Figure 1, L1, L2, L3 three-line is set respectively, for 3 circuits, the utility model is specifically described.
Embodiment one:
When 3 circuits are not all powered, the equal attonity of KA1, KA2, KA3, device non-transformer exports, and no signal exports.
Embodiment two:
When only there being L1 to power, KA1 often opens adhesive, normally closed disconnection, KA2, KA3 attonity, and device provides direct current and AC power, and single-chip microcomputer is in running order, and now, P1.1 is input as 1, P1.2, P1.3 is input as 0, corresponding output state feedback signal.
Embodiment three:
When only there being L2 to power, KA2 often opens adhesive, normally closed disconnection, KA1, KA3 attonity, and device provides direct current and AC power, and single-chip microcomputer is in running order, and now, P1.2 is input as 1, P1.2, P1.3 is input as 0, corresponding output state feedback signal.
Embodiment four:
When only there being L3 to power, KA3 often opens adhesive, normally closed disconnection, KA1, KA2 attonity, and device provides direct current and AC power, and single-chip microcomputer is in running order, and now, P1.3 is input as 1, P1.1, P1.2 is input as 0, corresponding output state feedback signal.
Embodiment five:
When have in L1, L2, L3 two-way or above power simultaneously time, the equal adhesive of the relay that power supply circuits are corresponding, but power supply order L1 > L2 > L3, namely when L1 powers, even if L2, L3 power simultaneously, system still only adopts L1 as power supply, by that analogy.Now, single-chip microcomputer is in running order, and due to the normal adhesive of relay, therefore single-chip microcomputer input signal still represents line status, and single-chip microcomputer exports corresponding status feedback signal.
Compared with prior art, the utility model has the advantage of, provide DC power supply by AC-DC change-over circuit, the power supply that transformer regulating relay sends gives outside use, is collected by signal processing circuit, is sent signal, carries out controlling and monitors.
