Description
Technical field
The present invention relates to a kind of on-off controller, relate in particular to a kind of PC level Double-power controller.
Background technology
ATSE is mainly used in emergency power supply system, is load Cong Yi road power supply to be transformed into the device for switching of an other road (standby) power supply, to guarantee that important load is continuous, reliability service.Once conversion unsuccessfully can cause important load power-off, may bring heavy economic losses and the critical security of the lives and property.
The research and production that China changes electrical equipment automatically in the nineties also in space state, also without national standard.The mid-90, the automatic transfer switching electric appliances such as Japan, France, the U.S. are successively squeezed into Chinese market, have alleviated to a certain extent the demand of China market.The automatic transfer switching electric appliance manufacturing enterprise of China (especially CBJi ATSE enterprise) increased sharply in recent years, its properties of product, quality differ, select and cause certain difficulty to design, use department, also due to ATSE is selected and improper use, to national wealth, cause very large loss.
Automatic switch electrical equipment is divided into PC and CB level.What represent PC level is to have world-class U.S. ASCO and ONAN, represents the Schneider that having of CB level is French.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of PC level Double-power controller.
The present invention for achieving the above object, adopts following technical scheme:
A kind of PC level of the present invention Double-power controller, comprise microprocessor, voltage sampling circuit, position of the switch testing circuit, fire protection circuit, drive circuit and power circuit, wherein the output of voltage sampling circuit, position of the switch testing circuit and fire protection circuit connects respectively the input of microprocessor, the input of the output termination drive circuit of microprocessor, described power supply gives appeal each circuit supply.
Preferably, on described microprocessor, asynchronous communication module is also set.
Preferably, on described microprocessor, keyboard circuit is also set.
Preferably, on described microprocessor, display circuit is also set.
Preferably, described microprocessor adopts PSoC series monolithic.
The present invention combines the function of the Double-power controllers such as Schneider, ABB, in change-over time, owes overvoltage and arranges artificially adjustablely, and visualization interface shows.Also integrated phase sequence function and RS485 communication, Default Value also can be cancelled two position feed back signals (two formulas) that divide for two minute positions (three-position type), and three-position type can prevent that load phase sequence from connecing instead.Simultaneously can with host computer communication well, carry out remote signalling, remote measurement, remote control, remote regulating.

Two-way transformer power taking for the active and standby power acquisition of the present invention, integrated two kinds of linear voltage regulators, produce two-way power supply ，Yi road and show that to singlechip chip, LED, LCD power supply ，Yi road, to optocoupler, relay power supply, guarantees the reasonable distribution of power supply;
The essence that the present invention is directed to ATSE adopts accurate voltage detecting circuit, and real-time sampled voltage signal judges that voltage failure (owe overvoltage, decompression, disconnected phase, phase sequence connects instead) signal gives scm managing system exactly;
The position of the switch of the present invention testing circuit adopts optical coupling isolation circuit for detection of present load power supply service condition, and gives scm managing system by detection signal.
Fire protection circuit of the present invention can be inputted or passive input by DC24V fire-fighting signal, for detecting timely fire-fighting alarm signal, gives scm managing system.
Scm managing system of the present invention after having accepted voltage sampling signal, position of the switch detection signal and fire-fighting alarm signal with the normative reference comparison, the judgement that arrange, final output signal reaches the object of Switching power with the reasonable running of drive motors to drive circuit, can export fire-fighting link and generator enabling signal simultaneously.
LED of the present invention LCD display circuit can be real-time the current line power state of demonstration, the current state of duplicate supply working method and switch.Facilitate user's change, parameters and understand clearly in time present load and power supply situation.
Communicating circuit of the present invention is followed MODBUS-RTU agreement and is adopted RS 485 interfaces, by can long-rangely carrying out 4 distant (remote signalling, remote measurement, remote control, remote regulating) with being connected of host computer.
