Description
Technical field
The utility model relates to a kind of switch actuator.
Background technology
Switch comprises mechanical switch, transistor switch and relay etc., all is that those switches directly are connected with the CPU of system in existing technology, has so not only received 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 the utility model provides a kind of switch actuator, can be used as the execution switch of electric equipment, can independently be provided with, and it is connected use with intelligence system, have a plurality of control ports.
The utility model 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; Said driving switch circuit is used to drive the consumer of back level, and the power input of said consumer is provided with a current transformer, and the output terminal of described current transformer is connected with described MCU.
In the utility model one embodiment, described driving switch circuit adopts the circuit structure of relay, controllable silicon or solid-state relay.
In the utility model one embodiment, 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 utlity model 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 the utility model circuit catenation principle block diagram.
Fig. 2 is the circuit catenation principle figure of another embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, the utility model provides a kind of switch actuator, comprises a MCU, it is characterized in that: described MCU is connected with 485 bus circuits, driving switch circuit and a toggle switch; Said driving switch circuit is used to drive the consumer of back level, and the power input of said 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.
The switch of the utility model 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 is the switch of controlling and driving on-off circuit driving consumer then.Simultaneously, the utility model is also gathered 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 utility model; In the present embodiment, described driving switch we adopt buffer circuit to connect power driving circuit composition, owing to the utlity model has independently MCU; Therefore control port is many, and it can be provided with according to the needs of different consumers.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
