Abstract
The utility model relates to an automatic transfer switch which outputs power through a programmable contact. The automatic transfer switch comprises a singlechip, a screen display and a keystroke which are respectively connected with the input port and the output port of the singlechip, and in addition two optical couplers, two resistors and two relays; two output ports of the singlechip are connected with the input terminals of the two optical couplers through the two resistors; the output terminals of the two optical couplers are grounded; the collector output terminals of the two optical couplers are respectively connected with a relay coil in series; the other end of the relay coil is connected with the positive end of the working electrical source of the relay; the emitter output terminals of the two optical couplers are respectively grounded; the constant-open contacts of the two relays are the signal output contacts. Since the automatic transfer switch is provided with two optical couplers, two relays and two resistors and the peripheral hardware circuit is provided with two independent programmable output contacts, control programs can be adjusted through communication or user protocols after being written into the singlechip, thus laying a foundation for improving the automatization and informationization of a power distribution system in which the automatic transfer switch is arranged.
Description
Technical field
The utility model belongs to a kind of intelligent electric element, particularly relates to a kind of automatic change over programmable contact output function.
Background technology
Modern industrialization has proposed very high requirement to the reliability and the intelligent management thereof of operation of power networks, increasing substantially of the widespread use of microprocessing and computer system security, promoted developing rapidly of intelligent electric appliance element, intelligentized low-voltage distribution system is then arisen at the historic moment.Thereby automated system safety such as grid automation, factory automation, process control automation, intelligent building, reliable, economic operation have been guaranteed.Exploitation and industrialization as the intellectuality of industrialization, informationalized basic device, the automatic change over that can communicate by letter are very important.At present,, far can not satisfy the needs of Intelligent Low Voltage Distribution System though there is the part automatic change over to have the branch state that closes that communication function still only limits to upload power source voltage state and switch,
Summary of the invention
The utility model provides a kind of automatic change over programmable contact output function that can increase the output of on off state information after single-chip microcomputer is set control program for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: it includes single-chip microcomputer, screen display and button; The input end of described screen display connects the output terminal of single-chip microcomputer, and the output terminal of button connects the input end of single-chip microcomputer, and it also includes two optocouplers, two resistance and two relays; Two output ports of described single-chip microcomputer are connected with the input end of two optocouplers by two resistance respectively, and another input end of two optocouplers is ground connection respectively; The collector output of two optocouplers is each and the coil tandem of a relay respectively, and the other end of coil is succeeded the anode of electrical work power supply; The emitter output terminal of two optocouplers is ground connection respectively; Two relays normally opened contact separately is the contact of output signal.
Advantage and the good effect that the utlity model has are: because device has and comprises two optocouplers, the peripheral hardware circuit of two relays and two resistance has two groups of independently programmable contact outputs, behind the control program that has write single-chip microcomputer, be provided with by communication function or User Agreement.The contact output function that can provide is: single-chip microcomputer self diagnosis fault, process control fault, action pre-alarm, programmable load Control Node, standby power supply monitoring.The utility model lays the foundation for the robotization and the level of informatization that improves automatic change over place distribution system.
