The physical interfaces are connected with the fitting with a preset unique address. The microcontroller is provided with a plurality of first address wires which are not grounded and one grounded second address wire, and the first address wires are respectively connected with a power source through a pull-up resistor. Each physical interface is connected with the second address wire of the microcontroller and selectively connected with one or more of the first address wires of the microcontroller. According to the interface device, the type of the fitting can be judged according to the address of the fitting, the structure is simple, implementation is easy, the implementation cost is low and the reliability is high. The interface device is provided with the different physical interfaces so that various fittings can be externally connected conveniently, and has the advantages of being high in applicability and good in application prospect.
Description
Technical field
The utility model relates to a kind of interface arrangement, especially relates to a kind of interface arrangement of self-identifying external accessories.
Background technology
In industrial circle, some equipment has the accessory that can change, and the model of accessory is more, and the accessory of different model may be by different manufacturers production.Therefore, equipment need to, under the prerequisite of identification accessory, normally be used between ability and accessory.
Have the approach that realizes external accessories identification now more.Such as, different accessories can be pasted sign at its conspicuous position, after installation, is input to system according to this sign is manual again, and still, this mode needs manual input identification information, wastes time and energy and easily makes mistakes.Again such as, whether by mechanical switch or optoelectronic switch, detect accessory is in place, this mode can only detect accessory whether accurately according to, do not mean accurately to identify accessory and promptly and accurately install yet, and install that switch need to increase cost and reliability is poor.
The utility model content
For overcoming the defect of prior art, the utility model proposes a kind of simple in structure, reliable operation and realize the interface arrangement of lower-cost self-identifying external accessories.
The utility model adopts following technical scheme to realize: a kind of interface arrangement of self-identifying external accessories, it comprise microcontroller, from several different physical interfaces that microcontroller is connected, this physical interface is connected with the accessory with default unique address; Microcontroller has second address wire of some earth-free the first address wires and ground connection, and the first all address wires connects power supply by a pull-up resistor respectively; Each physical interface all connects the second address wire of microcontroller and optionally connects wherein one or more first address wire of microcontroller.
Wherein, microcontroller can be single-chip microcomputer or dsp controller.
Wherein, accessory has a connecting interface matched with one of them physical interface.
Compared with prior art, the utlity model has following beneficial effect:
The interface arrangement the utility model proposes, can judge the type of accessory by the address of accessory, simple in structure, realize simple, realize that cost is lower and reliability is high.And, be provided with a plurality of different physical interfaces in the utility model interface arrangement to facilitate external various types of accessory, therefore the utlity model has preferably applicability, tool has a broad prospect of the use.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the circuit diagram of an embodiment of the utility model.
Embodiment
As shown in Figure 1, the utility model proposes a kind of interface arrangement of self-identifying external accessories, this interface arrangement comprises having some address wires (such as having drawn 6 address wires in Fig. 1, be designated as successively address wire A0～A5) microcontroller, wherein, the address wire of microcontroller is included as second address wire (as address wire A5 in Fig. 1) ground connection of earth-free some the first address wires (as address wire A0～A4 in Fig. 1) and ground connection, and the first all address wires meets power supply VCC by a pull-up resistor respectively; The physical interface that several are connected with microcontroller, wherein, each physical interface all connects the second address wire of microcontroller, and each physical interface optionally connects wherein one or more first address wire of microcontroller.
Therefore, according to accessory physical interface and interface features, a plurality of different physical interfaces can be set.And accessory has a connecting interface matched with one of them physical interface of interface arrangement.
Wherein, microcontroller can be single-chip microcomputer or dsp controller.
In addition, for dissimilar accessory, each accessory is preset a unique address.In conjunction with an embodiment shown in Fig. 2, the address pins bit0 of this accessory, bit3 are connected with bit5, and other address pins are unsettled.When this accessory, with interface arrangement, be connected by a physical interface, the address wire A0 of microcontroller～address wire A5 is connected with the address pins bit0 of this accessory～bit5 respectively.By microcontroller, by the address value of reading address line A0～address wire A5, this address value is unique and a kind of accessory is corresponding, thereby realizes the self-identifying to external accessories.
To sum up, the interface arrangement the utility model proposes, can judge the type of accessory by the address of external accessories, simple in structure, realize simple, realize that cost is lower and reliability is high.And, be provided with a plurality of different physical interfaces in the utility model interface arrangement to facilitate external various types of accessory, therefore the utlity model has preferably applicability, tool has a broad prospect of the use.
The above is only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, is equal to and replaces and improvement etc., within all should being included in protection domain of the present utility model.
