Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
The present invention is provided with tooth header reading device on proving installation, when plug-in unit is tested, plug-in unit inserts proving installation, tooth header reading device reads the identification characteristics information of anti-plug side set head on this plug-in unit, send to PC, PC drives proving installation plug-in unit is tested according to identification characteristics information setting test environment.Because of identification characteristics information and plug-in unit are unique corresponding, like this, relatively manually set according to identification characteristics information automatic setting test environment, can improve the accuracy rate and the efficient of plug-in unit identification effectively.
Referring to Fig. 2, the plug-in unit recognition system of universal test interface of the present invention is shown, comprise plug-in unit 1 and proving installation 3, plug-in unit 1 has rectangular insert 2, and rectangular insert 2 is provided with anti-plug side set head 8; Proving installation 3 has rectangular receptacle 4 and tooth header reading device 7; PC 6 is connected with proving installation 3 by test cable 5.
During probe card 1, plug-in unit 1 is inserted proving installation 3, wherein, rectangular insert 2 inserts rectangular receptacle 4, makes plug-in unit 1 and proving installation 3 carry out information interaction; Anti-plug side set head 8 contacts with tooth header reading device 7, and tooth header reading device 7 reads the identification characteristics information of anti-plug side set head 8, sends to proving installation 3, and shows.Proving installation 3 sends to PC 6 with identification characteristics information, and PC 6 loads corresponding testing program automatically according to identification characteristics information, makes up test environment, drives 3 pairs of plug-in units 1 of proving installation and detects.
Referring to Fig. 3, tooth header reading device 7 structural drawing of the present invention are shown.Tooth header reading device 7 comprises the shake-up display of 12 groups of parallel connections, and it is identical that each group is touched display device structure.Touching display with first group is example, touches display and comprises microswitch K1 and light emitting diode D1, and the fixed contact of microswitch K1 is connected with the anode of light emitting diode D1, and connects signal output part D01; Second moving contact (2) is connected and ground connection with the negative electrode of light emitting diode D1 by resistance R 1, and first moving contact (1) is connected with positive source.
When microswitch K1 is in second moving contact (2) position (default conditions), entire circuit is an off state, digital quantity signal output terminal D01 is equivalent to directly link to each other with ground, therefore light emitting diode D1 is a low level, promptly be output as 0 signal, light emitting diode D1 is because of positive ending grounding simultaneously, and no current flows through, and is non-luminous state.
When plug-in unit 1 inserts proving installation 3, anti-plug side set head 8 contacts with tooth header reading device 7, microswitch K1 is touched, when making microswitch K1 be in first moving contact (1) position, form the closed-loop path, digital quantity signal output terminal D01 be equivalent to directly and+5V links to each other, light emitting diode D1 high level at this moment, light emitting diode D1 is luminance because in the loop electric current process is arranged.
Anti-plug side set head 8 has a plurality of location points, each location point is corresponding one by one with each microswitch of tooth header reading device 7, as this location point tooth is arranged, and tooth can touch microswitch, make the digital quantity signal output terminal output high level of this microswitch correspondence, lumination of light emitting diode; Do not have tooth as this location point, just can not touch microswitch, the digital quantity signal output terminal output low level of this microswitch correspondence, light emitting diode is not luminous.
In conjunction with Fig. 2 and Fig. 3, the concrete course of work is as follows.
When plug-in unit 1 was not connected with proving installation 3, microswitch K1-K12 was in 2 positions of acquiescence, and promptly circuit is an off-state, the equal output low level of digital quantity signal output terminal D01-D012;
When plug-in unit 1 with after proving installation 3 is connected, anti-plug side set head 8 can be pushed corresponding microswitch K1-K12 on the plug-in unit 48 core rectangular inserts, corresponding microswitch K1-K12 is placed 1 position, partial circuit constitutes the closed-loop path, therefore corresponding digital amount output terminal can be exported high level, and corresponding simultaneously light emitting diode also can be lighted.
No. 12 microswitches disconnect or closed information, can represent the combination of 2^12=4096 kind high-low level in theory, can distinguish the information of 4096 kinds of different electronic housing plug-in units, much larger than the quantity of present package types.Proving installation detects 12 tunnel digital quantity output signal, and testing result is transferred to PC 6 by test cable line 5, PC 6 fully can be according to the various plug-in units 1 of not homotactic high-low level signal distinguishing, automatically load corresponding testing program, make up test environment, plug-in unit 1 is detected.
Plug-in unit 1 separates with proving installation 3 after end of test (EOT), and the microswitch in the proving installation 3 also returns to initial state, and promptly entire circuit is also recovered initial off-state.
The above only is a preferred implementation of the present invention, does not constitute the qualification to protection domain of the present invention.Any any modification of being done within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present invention.
