Detecting unit is connected with described socket, is used to detect the duty of button on the described keying panel;
Display unit is connected with described detecting unit, is used to show the testing result of described detecting unit.
The utility model embodiment has reduced manufacturing cost by simplifying the keying panel pick-up unit, also makes the operation of keying panel pick-up unit become simpler.
Description of drawings
Fig. 1 is the structure principle chart of the keying panel pick-up unit that provides of the utility model embodiment;
Fig. 2 is the circuit structure diagram of the keying panel pick-up unit that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model embodiment has reduced manufacturing cost by the simplification to the keying panel pick-up unit, also makes the operation of keying panel pick-up unit become simpler.
The utility model embodiment provides a kind of keying panel pick-up unit, and described keying panel pick-up unit comprises:
Socket is used to connect described keying panel pick-up unit and keying panel;
Detecting unit is connected with described socket, is used to detect the duty of button on the described keying panel;
Display unit is connected with described detecting unit, is used to show the testing result of described detecting unit.
Embodiment one:
Fig. 1 shows the structure principle chart of the analog signal processing system that the utility model embodiment provides, and only shows the part relevant with the utility model embodiment for convenience of explanation.
Detecting unit 12 is connected with socket 11, is used to detect the duty of button on the keying panel;
In real work, socket 11 is connected with the keying panel interface, and by socket 11 keying panel is connected with detecting unit 12.Press any one button of keying panel, if this button is working properly, will change the duty of detecting unit 12, and this change is found expression in the display unit place by interface.If this button cisco unity malfunction then can not change the work of detecting unit 12, and can reflect the state of button cisco unity malfunction by display unit 13.
In the present embodiment, the user only need press the button on the keying panel simply, and then whether the duty of this button normally can be judged according to display unit.Simple to operate, the intuitive display of this method of testing, and convenient efficient.
Embodiment two:
Fig. 2 shows the circuit structure diagram of the keying panel pick-up unit that the utility model embodiment provides, and only shows the part relevant with the utility model embodiment for convenience of explanation.
Jack is used to connect described keying panel pick-up unit and keying panel.
Detecting unit 12 comprises:
Power supply V is used for providing required voltage to test circuit;
Divider resistance R1, its first end is connected with power supply V;
Divider resistance R2, its first end is connected with power supply V;
Divider resistance R3, its first end is connected with divider resistance R1 second end, its second end ground connection;
Divider resistance R4, its first end is connected with divider resistance R2 second end, its second end ground connection;
Positive-negative-positive triode Q, its emitter is connected with divider resistance R1 second end, is used for as contactor;
Divider resistance R5, its first end is connected with the collector of positive-negative-positive triode Q;
Divider resistance R6, its first end is connected with the node of divider resistance R2 with positive-negative-positive triode Q base stage, and its second end is connected with socket B.
Light emitting diode (LED), its anode is connected with second end of divider resistance R5, and its plus earth is used for the duty of display button.
In real work, by socket with keying panel to be detected with after the keying panel pick-up unit is connected, the base stage of positive-negative-positive triode Q is a high level under usual situation, positive-negative-positive triode Q is in cut-off state, do not have electric current to flow through on the light emitting diode (LED), light emitting diode (LED) is not luminous.If the button operate as normal, when the tester pressed button on the keying panel, the base stage of positive-negative-positive triode Q will be dragged down, and this moment, positive-negative-positive triode Q was in conducting state, and electric current flows through light emitting diode (LED) and makes it luminous.If after pushing button, light emitting diode (LED) is not luminous, and the button cisco unity malfunction on the keying panel then is described.
In the present embodiment, utilize simple test philosophy, operation and simplified the pick-up unit of making flow process, reduced the detection cost of keying panel.
The utility model embodiment has reduced manufacturing cost by simplifying the keying panel pick-up unit, also makes the operation of keying panel pick-up unit become simpler.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
