Description
Technical field
The utility model relates to the motor protection field, relates in particular to intelligent motor protector.
Background technology
At present; in the motor protection field; continuous development along with microelectric technique; the function of motor protector (hereinafter to be referred as protector) also from strength to strength; from original only providing the fault state of motor emerged in operation is protected; to the multi-function protector of realizing integrating control, protection, monitoring and bus communication; the function that is realized is more and more; the thing followed be the volume of protector also in continuous increase, but this is opposing with the microminiaturized developing direction of low-voltage electrical apparatus.Existing in the market multi-function protector product structure is generally all bigger; inner element function distribution adopts the multi-layer PCB layout type; bottom is a power supply; the centre is controls such as various IO input and output; top layer is functional modules such as communication, analog quantity, and other also have some functional layers, and these components and parts generally all adopt and directly are welded in the PCB printed board; cause the area of PCB all bigger, thereby make the overall volume of protector bigger.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the defective that above-mentioned prior art exists, a kind of intelligent motor protector simple in structure to be provided.
The purpose of this utility model can be achieved through the following technical solutions: intelligent motor protector; it is characterized in that; this protector comprises shell; the top layer pcb board; CPU and signal processing circuit pcb board; power supply and DO output circuit pcb board; described outer casing inner wall is provided with pcb board groove guide rail; described top layer pcb board; CPU and signal processing circuit pcb board; power supply and DO output circuit pcb board are vertically arranged in the enclosure from top to bottom; described top layer pcb board; CPU and signal processing circuit pcb board; power supply and DO output circuit place pcb board interconnect; described CPU and signal processing circuit pcb board are provided with CPU; signal processing circuit, described power supply and DO output circuit pcb board are provided with power module and DO output circuit.
Described top layer pcb board, this top layer pcb board are provided with communication module interface, DI input module interface, analog output interface circuit and show connector etc.
Also comprise communication module, the setting of this communication module is connected with top layer pcb board communication module interface.
Also comprise the DI input module, the setting of this DI input module is connected with top layer pcb board DI input module interface.
Also comprise analog output module, this analog output module is connected with top layer pcb board analog output interface circuit.
Also comprise the split display unit, this split display unit shows that with the top layer pcb board connector is connected.
Compared with prior art, advantage of the present utility model comprises:
(1) conserve space: adopt this mode to carry out the volume that layout can be dwindled protector greatly, on the basis of realizing identical function, the overall dimensions structure of protector can be dwindled more than 1/3;
(2) maintain easily: protector adopts greatly convenient for maintaining of this layout, owing to only kept basic functions, in case then protector breaks down, then is easy to search its fault point, and because the PCB number of plies has been lacked, has made things convenient for the operation of detecting instrument;
(3) save cost:, then significantly reduced the area of PCB, thereby reduced the cost of protector because protector has only kept basic functions.

Wherein: 1 is the protector main body cover; 2 is top layer connection PCB plate; 3 are function pcb boards such as communication and analog quantity, and 4 is CPU and IO input and output place pcb board, and 5 is signal processing circuit place pcb board; 6 is power supply place PCB; 121 is the protector main body cover, and 122 is top layer connection PCB plate, and 123 is various functional modules; 124 is CPU and signal processing circuit pcb board, and 125 is power supply and DO output circuit pcb board.
Embodiment
Below in conjunction with specific embodiment the utility model is described further.
As Fig. 1; shown in Figure 2; the utility model is mainly by top layer connection PCB plate 122; CPU and signal processing circuit pcb board 124 and power supply and DO output circuit pcb board 125 couple together through the associated fitting; forming a protector that has basic function is installed in 121 protector outer casings; wherein be reserved with various expandable functions module interfaces on the top layer connection PCB plate 122 (as communication; analog quantity; DI; show etc.); in case need other function, only need with corresponding various functional module 123 (communication modules; analog module; DI module etc.) be installed on the interface of reservation and get final product.
This is a kind of new function distribution method; various nonessential functional module in the protector is independent; make independent one by one functional module; only keep basic functions and form a protector; and it is carried out function cut apart with pcb board and draw; and in the protector of this basic function, keep the interface of installation function module, make things convenient for the function expansion.In case the function (as communication, analog quantity output, DI input function etc.) that protector need be except that basic function then only need be installed to corresponding functional modules on the interface into its reservation and gets final product.
Intelligent motor protector; this protector comprises shell; the top layer pcb board; CPU and signal processing circuit pcb board; power supply and DO output circuit pcb board; described outer casing inner wall is provided with pcb board groove guide rail; described top layer pcb board; CPU and signal processing circuit pcb board; power supply and DO output circuit pcb board are vertically arranged in the enclosure from top to bottom; described top layer pcb board; CPU and signal processing circuit pcb board; power supply and DO output circuit place pcb board interconnect; described CPU and signal processing circuit pcb board are provided with CPU; signal processing circuit, described power supply and DO output circuit pcb board are provided with power module and DO output circuit.Described top layer pcb board, this top layer pcb board are provided with communication module interface, DI input module interface.Also comprise communication module, the setting of this communication module is connected with top layer pcb board communication module interface.Also comprise the DI input module, the setting of this DI input module is connected with top layer pcb board DI input module interface.
