Description
Technical field
The present invention relates to power supply control technology fields, and in particular to a kind of power input automatic switching controller and controlling party
Method.
Background technique
Currently, some occasions are higher to the uninterrupted time requirement of AC power supplies, and break time is more than to want finding limit that can lose number
According to or damage equipment, but the design of current power supply does not have the function of automatically switching generally, cannot play automatic protection data
Or the function of equipment.
Summary of the invention
In view of the deficiencies of the prior art, the present invention is intended to provide a kind of power input automatic switching controller and controlling party
Method.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of power input automatic switching controller, including the independent AC power supplies input of two-way, are all the way uninterruptible power supply,
Another way is alternating current AC power supplies, and the uninterruptible power supply and alternating current AC power supplies are connected to control output unit one and control defeated
Unit two out；It further include having sampling unit and judging control unit；The sampling unit communication connection controls single in the judgement
Member is sampled and transmits for each voltage waveform to the connection line between uninterruptible power supply and control output unit one
To described control unit 106；The judgement control unit communication connection is in the control output unit one and control output unit
Two, for receiving the sampled signal of the sampling unit and judging whether uninterruptible power supply has control output described in voltage input single
It in member one, when detecting no, controls the control output unit one and stops out-put supply, and it is single to control the control output
Member two starts out-put supply.
Further, the voltage rating of power supply output is 220V, rated output power 2KW.
The present invention also provides a kind of method using above-mentioned power input automatic switching controller, specifically:
Under normal condition, judge that control unit control control output unit one carries out power supply output, and control is forbidden to export
Two out-put supply of unit；
Sampling unit is persistently to each voltage waveform of the connection line between uninterruptible power supply and control output unit one
It is sampled, and sampled signal is transmitted to judgement control unit；Judge that control unit receives the sampling letter of the sampling unit
After number, judge whether uninterruptible power supply has in control output unit one described in voltage input, when detecting no, described in control
It controls output unit one and stops out-put supply, and control the control output unit two and start out-put supply.
The beneficial effects of the present invention are: alternating current input may be implemented in the present invention and the automatic of uninterruptible power supply ox input cuts
It changes, switching time is short, eliminates device data loss or equipment damage phenomenon.Switching time completes in 0-20ms.
Detailed description of the invention
Fig. 1 is the controller architecture schematic diagram of the embodiment of the present invention 1.
Specific embodiment
