Description
Technical field
The utility model is related to a kind of PLC UPS power supply control apparatus more particularly to a kind of PLC use that can switch online
UPS power supply control apparatus, belongs to control technology field.
Background technology
Existing PLC control system power supply system is by a set of UPS single services, as shown in Figure 1.Once being supplied to UPS
When electric system breaks down or UPS failures itself are unable to timely processing, PLC system can be caused to be stopped, and then cause
All devices are out of hand, if blast furnace is uncontrolled, cause immeasurable economic loss to enterprise, or even occur large-scale
Safety accident.Therefore, how to improve PLC control system stable power-supplying just becomes the problem to be captured of all technical staff.
Invention content
The technical problem to be solved by the present invention is to provide a kind of PLC that can switch online UPS power supply control apparatus.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of PLC that can switch online UPS power supply control apparatus, including two sets of USP power supply systems UPS1-UPS2, three
A circuit breaker Q F1-QF3, MX150 microcontroller change-over switch；Described device is connected in current supply circuit, two sets of USP power supplies
System UPS1-UPS2 respectively through circuit breaker Q F1 and circuit breaker Q F2 be connected on MX150 microcontroller change-over switches S1 input terminals and
S2 input terminals, two sets of USP power supply systems UPS1-UPS2 are often for 220VAC power supplys；The output of MX150 microcontroller change-over switches
End S3 connects the total power switch of PLC system.
Device further includes MX150 change-over switch control panels, when default input voltage, predeterminated frequency, switching can be arranged
Between, the technical parameters such as switchback time.If the failure of UPS1 power supply systems causes output voltage to be less than predeterminated voltage, MX150
Change-over switch can be switched to and be powered by the roads UPS2 moment, and MX150 change-over switches can be automatic after 5 seconds when the roads UPS1 system is normal
It is switched to the power supply of the roads UPS1, it is ensured that PLC system power supply is normal, and PLC operations will not be interrupted.
Using having technical effect that acquired by above-mentioned technical proposal：
The utility model still can be stablized when making PLC control system when UPS breaks down or alternating current failure
Operation ensures production normal operation.
Description of the drawings
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the principles of the present invention block diagram；
Fig. 2 is the element wiring diagram of the utility model.
Specific implementation mode
Embodiment 1：
A kind of PLC that can switch online UPS power supply control apparatus, including two sets of USP power supply systems UPS1-UPS2, three
A circuit breaker Q F1-QF3, MX150 microcontroller change-over switch；Described device is connected in current supply circuit, two sets of USP power supplies
System UPS1-UPS2 respectively through circuit breaker Q F1 and circuit breaker Q F2 be connected on MX150 microcontroller change-over switches S1 input terminals and
S2 input terminals, two sets of USP power supply systems UPS1-UPS2 are often for 220VAC power supplys；The output of MX150 microcontroller change-over switches
End S3 connects the total power switch of PLC system；When USP power supply systems UPS1 breaks down, the control of MX150 microcontroller change-over switches
Circuit breaker Q F1 is disconnected, and circuit breaker Q F2 is closed.
In normal operating conditions, UPS1 out-put supplies are input to MX150 change-over switches by the roads S1 and power for PLC system.
When carrying out self-supporting UPS1 power supply systems and breaking down, UPS1 can be switched to battery powered, it is ensured that PLC system power supply is normal, meeting simultaneously
There are UPS1 failure alarm signals to export to DCS terminals.
Since UPS battery power-on time is limited, when UPS1 batteries exhaust, MX150 change-over switches can moment be switched to by
The roads UPS2 power, and MX150 change-over switches can automatically switch to the power supply of the roads UPS1 after 5 seconds when the roads UPS1 system is normal, it is ensured that
PLC system power supply is normal, and PLC operations will not be interrupted.
Device further includes MX150 change-over switch control panels, when default input voltage, predeterminated frequency, switching can be arranged
Between, the technical parameters such as switchback time.If the failure of UPS1 power supply systems causes output voltage to be less than predeterminated voltage, MX150
Change-over switch can be switched to and be powered by the roads UPS2 moment, and MX150 change-over switches can be automatic after 5 seconds when the roads UPS1 system is normal
It is switched to the power supply of the roads UPS1, it is ensured that PLC system power supply is normal, and PLC operations will not be interrupted.
The utility model is mainly used in：Large automatic control system, such as DCS, PLC dispatch control system, important control
The exchange control section of circuit.The circuit can effectively avoid the control system caused by the reasons such as instantaneous low-voltage, system dead electricity
It is unable to control field device；And it can continue control all devices when electric system all the way is broken down and avoid production thing
Therefore and safety accident occur, for quickly solution electric power system fault help is provided.
