Abstract
The invention relates to a switch actuator which comprises a microprogrammed control unit (MCU). The switch actuator is characterized in that the MCU is connected with a 485 bus circuit, a driving switch circuit and a dial switch, wherein the driving switch circuit is used for driving electric equipment in a backward stage, a current transformer is arranged at a power input end of the electric equipment, and an output end of the current transformer is connected with the MCU. The switch actuator can be used as an actuating switch of electrical equipment, can be independently arranged, and can be used by being connected with an intelligent system, not only are the number of control ports is large, but also the switch actuator has a current detection function, an overload and overcurrent protection function and other functions, and the switch actuator has good practical value.
Description
Technical field
The present invention relates to a kind of switch actuator.
Background technology
Switch comprises mechanical switch, transistor switch and relay etc., all is that these switches directly are connected with the CPU of system in existing technology, so not only has been subjected to the restriction of cpu port, and because the problem of circuit can't be accomplished the control of long distance.
Summary of the invention
The purpose of this invention is to provide a kind of switch actuator, can be used as the execution switch of electric equipment, can independently arrange, it is connected use with intelligence system, have a plurality of control ports.
The present invention adopts following scheme to realize: a kind of switch actuator, comprise a MCU, and it is characterized in that: described MCU is connected with 485 bus circuits, driving switch circuit and a toggle switch; Described driving switch circuit is used for driving the consumer of back level, and the power input of described consumer is provided with a current transformer, and the output terminal of described current transformer is connected with described MCU.
In an embodiment of the present invention, described driving switch circuit adopts the circuit structure of relay, controllable silicon or solid-state relay.
In an embodiment of the present invention, described switch driving circuit comprises a buffer circuit; Described buffer circuit is controlled the consumer that a power driving circuit drives the back level.
The present invention has independently control module; not only control port is many, and has current detecting and functions such as overload and overcurrent protection, and it is connected with intelligence system can realize that an intelligent controller controls a plurality of consumers; circuit structure is simple, has certain practical value.
Description of drawings
Fig. 1 is circuit catenation principle block diagram of the present invention.
Fig. 2 is the circuit catenation principle figure of another embodiment of the present invention.
Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the invention provides a kind of switch actuator, comprise a MCU, it is characterized in that: described MCU is connected with 485 bus circuits, driving switch circuit and a toggle switch; Described driving switch circuit is used for driving the consumer of back level, and the power input of described consumer is provided with a current transformer, and the output terminal of described current transformer is connected with described MCU.Described driving switch circuit adopts the circuit structure of relay, controllable silicon or solid-state relay.
Switch of the present invention has independently MCU, and it has bus circuit, can receive the instruction of intelligence system, independently electric equipment is controlled, and when receiving instruction, MCU then controls the switch of driving switch drives consumer.Simultaneously, the present invention also gathers the electric current of consumer, feeds back to MCU, realizes current detecting and overload and overcurrent protection.
See also Fig. 2, Fig. 2 is the circuit catenation principle figure of another embodiment of the present invention, in the present embodiment, described driving switch we adopt buffer circuit to connect power driving circuit composition, because the present invention has independently MCU, therefore control port is many, and it can arrange according to the needs of different consumers.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
