Detailed description of the invention
Reference Fig. 1, a kind of network intelligence double copies power supply that the present invention proposes, including: master switch power supply, backup circuit breaker power supply, transformator, reset circuit, the first relay, overvoltage crowbar, delay circuit and the second relay.
Master switch power supply and backup circuit breaker power supply are all connected with the live wire of communication power supply, and the zero line of communication power supply and the first relay common port connect, and the normally opened end of the first relay and normal-closed end connect master switch power supply and backup circuit breaker power supply respectively.The zero line of communication power supply is connected with master switch power supply, then master switch power supply electrifying enters duty is load supplying；The zero line of communication power supply is connected with backup circuit breaker power supply, then backup circuit breaker power supply electrifying enters duty is load supplying.
First relay has two kinds of duties.Under first duty, it controls end and obtains high level, the first relay normally open end conducting, and normal-closed end disconnects, and the zero line of communication power supply is connected with master switch power supply, thus master switch power work；Under second duty, it controls end and does not powers on, and the first relay normally open end disconnects, and normal-closed end turns on, and the zero line of communication power supply is connected with backup circuit breaker power supply, thus backup circuit breaker power work.
The live wire of communication power supply and zero line are all connected with transformator, and transformator connects the first Control end by reset circuit.Communication power supply is powered for reset circuit after transformator transformation voltage stabilizing.Specifically, communication power supply is 220V alternating current power supply, and communication power supply exports 12V DC source after transformator and powers for reset circuit after the mu balanced circuit voltage stabilizing being arranged between transformator and reset circuit.Reset circuit obtain electric after produce a high level pulse signal and be supplied to the first Control end, thus the first relay enters the first duty.
In present embodiment, reset circuit uses RC reset circuit.
Master switch power supply connects the second Control end by delay circuit, and the second relay output end connects the first Control end.Second relay has two kinds of duties, and under the first duty, it controls end and powers on, its outfan output high level；Under second duty, it controls end dead electricity, and its outfan does not powers on.
After first relay enters the first duty, master switch power supply normally works and produces 12V DC voltage is that delay circuit is powered, delay circuit produces a permanent High level and drives the second relay to enter the first duty, its outfan provides a permanent High level signal to the first Control end, the first relay is made to keep the first duty, thus, master switch power supply normally works as load supplying.
In present embodiment, reset circuit is instantaneous signal for the high level signal that the first Control end provides, if master switch power failure, delay circuit cannot obtain master switch power supply and power, thus the second Control end dead electricity enters the second duty.Owing to the second relay under the second duty cannot provide high level for the first Control end, so, the first relay enters the second duty, and it is load supplying that backup circuit breaker power supply is connected entrance duty with 220V alternating current power supply.
In present embodiment, the setting of delay circuit, it is to avoid the second relay provides level signal and reset circuit interfering to the first Control end offer level signal to the first Control end.
In present embodiment, master switch power supply connects delay circuit by overvoltage crowbar, to avoid master switch power supply overvoltage to cause damage delay circuit and the second relay.Overvoltage crowbar uses LM393 chip, and its connection is provided with comparing the voltage stabilizing chip of voltage.Delay circuit uses NE555 chip to constitute.
In present embodiment, also include dual-colored LED display lamp such as red and green color LED light.Specifically, dual-colored LED display lamp can be connect altogether by two negative electrodes and the LED of ground connection forms, and the anode of one of them LED connects master switch power supply, and the anode of another LED connects backup circuit breaker power supply.When master switch power work, dual-colored LED display lamp shows the first coloured light such as green glow；When backup circuit breaker power work, dual-colored LED display lamp shows the second coloured light such as HONGGUANG.
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope that the invention discloses; according to technical scheme and inventive concept equivalent or change in addition thereof, all should contain within protection scope of the present invention.
