Embodiment
Elaborate below in conjunction with the utility model of embodiment, present embodiment has provided detailed embodiment being to implement under the prerequisite with technical solutions of the utility model, but protection domain of the present utility model is not limited to following embodiment.
Please refer to Fig. 1, Fig. 1 is a kind of circuit of multiple instrument and socket synoptic diagram of interface identified, wherein, socket 2 is a pair of plug socket, both sides connect 3 I/O signal wires 3 respectively, wherein, on one side 3 I/O signal wires 3 as input end, for example be designated as socket first input end P30, the socket second input end P31, socket the 3rd input end P32 respectively; 3 I/O signal wire ground connection of another side.
Please refer to Fig. 2, Fig. 2 is a kind of circuit of multiple instrument and plug construction synoptic diagram of interface identified, wherein, plug 1 is double plug, both sides connect 3 I/O signal wires 3 respectively, wherein, on one side 3 I/O signal wires 3 as input end, for example be designated as plug first input end P10, the plug second input end P11, plug the 3rd input end P12 respectively; 3 I/O signal wires 3 of another side for example are designated as the plug first output terminal P20, the plug second output terminal P21, plug the 3rd output terminal P22 respectively as output terminal.
Please refer to Fig. 3, Fig. 3 is a kind of circuit of multiple instrument and one-piece construction synoptic diagram of interface identified, the corresponding input end of the input end gang socket 2 of plug 1, the corresponding output terminal of the output terminal gang socket 2 of plug 1.I/O signal wire 3 is connected between the plug first input end P10 and the plug first output terminal P20 of plug 1, i.e. plug first input end P10 and the plug first output terminal P20 short circuit.The utility model is just lifted a preferred embodiment at this and is helped the technician to understand, and does not limit.
The input end of socket 2 is high level 1 under the state of not attachment plug 1 or plug 1 short circuit, is low level 0 under the state of attachment plug 1.(all short circuit just is equivalent to not attachment plug, the i.e. connection of part of part short circuit) adopts 3 I/O signal wires 3 in the present embodiment, can realize " 110 ", " 101 ", " 011 ", " 100 ", " 010 ", " 001 ", " 000 " seven kinds of signals, each signal is used for corresponding a kind of instrument, namely can be according to different plug short circuit modes, identify seven kinds of instruments, and " 111 " are exactly not have connection status (or whole short circuit state), not as cognizance code.After determining machine recognition code (seven kinds of above-mentioned signals), write corresponding communication program behind recording unit according to the communication modes of every class machine, recording unit just can be finished 7 kinds of dissimilar machine datas are recorded in the same data file.By that analogy, signal wire is more many, and the kind of recognition machine is just more many, and n root signal wire can be identified 2n-1 kind instrument.The plug that instrument is joined only need get final product by a corresponding output pin short circuit on the input signal pin that goes out plug 1 and next door.As being that P10 with plug 1 is connected with the P20 pin among the figure, insert socket 2,3 signal wire level that obtain are " 110 ".Again for example, instrument 4 is linked between P11, P12 and P21, the P22, inserts socket 2,3 signal wire level that obtain are " 001 ", and the utility model is not done remaining connected mode at this and given unnecessary details.
After recording unit powered on, regularly the query interface state connected on the recording unit when inquiring other equipment, and recording unit just can pass through interface signal recognition machine type, afterwards, with external device talk, notes real time data.Recording unit can store mass data, by special software, the data of storage can be derived, and forms a electronic document and preserves, and whole process need not to be manually recorded on the paper, is input in the computer again.Improved work efficiency, with no paper office is saved resource, environmental protection.
Useful technique effect of the present utility model is that this interface recognition method is simple, practical, as long as there is the instrument of communication interface can install supporting plug additional, and plug does not need power supply.It is also very big that the identification mouth of recording unit is expanded scope, easily.By this recognition interface, realize that multiple instrument data is recorded in the data recording unit, is conducive to data management and preservation, reduce the artificial interference factor, improved work efficiency, saved resource, for enterprise has made contribution in quality management, saved cost
More than disclosed only be the application's a specific embodiment, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
