Abstract
The utility model provides a testing structure of a line sequence of a serial port cable of a self-service device and belongs to the technical field of self-service products. The structure includes a serial port line. Two ends of the serial port line are both provided with 9-pin plugs. Pins of the plugs on the two ends of the serial port line connect with an I/O base pin of a single-chip microprocessor correspondingly through cables. An output terminal of the single-chip microprocessor also connects with a voice player and a display device. Compared with the prior art, the testing structure of the line sequence of the serial port cable of the self-service device in the utility model has characteristics of reasonable design, simple structure, skillful arrangement, convenient usage and the like. By using the testing structure of the line sequence of the serial port cable of the self-service device in the utility model, the quality of the cable can be judged accurately, and the line sequence can be drawn quickly. The testing structure of the line sequence of the serial port cable of the self-service device in the utility model has good spreading and applying value.
Description
Technical field
The utility model relates to a kind of self-service product technical field, specifically a kind of serial interface cable line preface test structure of Possum.
Background technology
Along with development of science and technology, Possum obtains increasing application because of its reliability and practicality, security, ease for maintenance, and has been widely used in industries such as communication, finance, government, traffic, medical treatment, industry and commerce, the tax.But the Serial Port Line cable that existing Possum uses, the connecting line preface is varied, has brought difficulty with regard to the test to cable like this, tests also cumbersomely, and inconvenient staff judges the line preface of cable and the quality of cable accurately.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves prior art, and a kind of serial interface cable line preface test structure of Possum simple in structure, easy to use is provided.
The technical scheme of the utility model realizes by following mode; The serial interface cable line preface test structure of this a kind of Possum; Its structure comprises Serial Port Line; The two ends of this Serial Port Line are provided with 9 pin plugs, and the stitch of said Serial Port Line two ends plug is through the corresponding I/O pin that connects single-chip microcomputer of cable, and the output terminal of this single-chip microcomputer also is connected with speech player and display device.
Described display device is a charactron.
The beneficial effect that the utility model is compared with prior art produced is:
Characteristics such as that the serial interface cable line preface test structure of a kind of Possum of the utility model has is simple in structure, easy to use, be skillfully constructed; Can accurately judge the quality of cable; And draw out the line preface of cable rapidly, and improving the test speed and the testing efficiency of Possum serial ports cable, measuring accuracy is high; Improve staff's work efficiency, be easy to promote the use of.
Description of drawings
Accompanying drawing 1 is the syndeton block diagram of the utility model.
Mark in the accompanying drawing is represented respectively:
1, Serial Port Line, 2, plug, 3, the I/O pin, 4, single-chip microcomputer, 5, cable, 6, speech player, 7, display device.
Embodiment
Below in conjunction with accompanying drawing the serial interface cable line preface test structure of a kind of Possum of the utility model is done following the detailed description.
For making things convenient for serial ports cable verification test; The convenient cable connection layout of drawing shown in accompanying drawing 1, provides the serial interface cable line preface test structure of this a kind of Possum at present; Its structure comprises Serial Port Line 1; The two ends of this Serial Port Line 1 are provided with 9 pin plugs 2, and the stitch of said Serial Port Line 1 two ends plug 2 is through the cable 5 corresponding I/O pins 3 that connect single-chip microcomputer 4, and the output terminal of this single-chip microcomputer 4 also is connected with speech player 6 and display device 7.
Described display device 7 is a charactron.
The I/O pin 3 of this device utilization single-chip microcomputer 4 connects the plug 2 of Serial Port Line 1 both sides respectively, then through the power supply power supply, begins the I/O pin 3 of scanning monolithic machine 4 after CPU powers on; And judge the line preface that both sides connect, and store the line preface get off respectively, report the connection situation of cable through charactron or voice; The connection layout of prefabricated cable compares with it; Judge whether the cable problem, so just can accurately judge the quality of cable, and draw out the line preface of cable rapidly.
