Abstract

The utility model provides a kind of fault detection equipment and mainly composes a USB sensing circuit, of which one end is connected with a measuring machine set to sense the signal generated by the measuring machine set and the other end is connected with a logic comparison judgment circuit. Moreover, the logic comparison judgment circuit is connected with a status display interface circuit, receives the signals output by the USB sensing circuit and judges whether the measuring machine set operates normally as per the signal, so that the status display interface circuit displays the working state of the measuring machine set. In addition, the logic comparison judgment circuit continuously controls whether the USB sensing circuit works normally through a light relay control circuit. The detection equipment proposed in the utility model is used to test various environmental stress of the measuring machine set, can timely monitor whether the measuring machine set operates under normal condition, greatly reduces labor burden and increases the quality reliability of the machine.

Description

A kind of failure detector
Technical field
The utility model relates to a kind of pick-up unit, relates in particular to a kind of device that is used for detection failure.
Background technology
General reliability-test need be put board to be measured into other stress tests such as doing temperature, humidity or vibrations in the proving installation, original reliability-test needs installing operating system or other testing software, and the tester must wait for constantly at the other software of controlling of board to be measured to judge whether have fault to take place.
Above-mentioned test mode is the wasting manpower and material resources not only, and is difficult to directly judge whether board to be measured has fault to take place.
Summary of the invention
In view of the above problems, the utility model provides a kind of pick-up unit whether board breaks down that is used to detect, and when this device produces fault, can learn fault fast, reduces the manpower burden and has increased fiduciary level.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of failure detector, and whether it is used for detecting board to be measured automatically and breaks down, and this device mainly comprises a circuit for detecting, the one end links to each other with a board to be measured, in order to detect the signal that this board to be measured produces; One logic compares decision circuitry, and the one end is connected with the above-mentioned circuit for detecting other end, and this logic relatively decision circuitry receives the signal of exporting through circuit for detecting, judges according to this signal whether this board to be measured operates normally and export one and judge signal; One status display interface circuit, it is connected with above-mentioned logic comparison decision circuitry, and receive above-mentioned judgement signal, according to judging that signal shows the state of board to be measured, utilize a LED lamp to show and the hummer sound that gives a warning shows the state of this board to be measured; And a control circuit, this control circuit is connected in above-mentioned logic relatively between decision circuitry and the circuit for detecting, according to the relatively running of the judgement signal controlling circuit for detecting of decision circuitry output of logic.
Preferable, the utility model provides a kind of failure detector, wherein, described control circuit is an optical relay control circuit, described circuit for detecting is a USB circuit for detecting, and this USB circuit for detecting is connected with board to be measured by a USB line, to detect and to receive the signal of board generation to be measured.
Above-mentioned technical scheme, when board to be measured was in the test of various environmental stresses, it was normal to monitor at any time whether this board judgement to be measured operates, when board to be measured breaks down, can learn fault fast, significantly reduce the fiduciary level of manpower burden and increase board quality.
Description of drawings
Fig. 1 is a block diagram of the present utility model
Embodiment
Please refer to shown in Figure 1, failure detector described in the utility model is used for monitoring at any time that a tester table is done periodically in an accommodation space that is difficult for observing, whether can normal operation during long-lasting stress test, when breaking down, can learn fault fast and remind the tester to handle.
This failure detector mainly comprises a board 10 to be measured, a USB circuit for detecting 20, a logic relatively decision circuitry 30, a status display interface circuit 40 and an optical relay control circuit 50.
Wherein, these USB circuit for detecting 20 1 ends are connected with this board 10 to be measured, its other end compares decision circuitry 30 with this logic and links to each other, this logic comparison decision circuitry 30 is connected with this status display interface circuit 40, in addition, this logic relatively decision circuitry 30 also by the whether normal operation of this optical relay control circuit 50 control USB circuit for detecting 20.
With this board 10 to be measured is example, should place in the accommodation space (not shown) by board 10 to be measured, and in this accommodation space this board 10 to be measured is carried out environmental stresses such as series of temperature, humidity and vibrations and test.This board 10 to be measured is connected with this USB circuit for detecting 20 by a USB line, after this board 10 to be measured is connected with the mains, USB keyboard on this board 10 to be measured produces one group of Num Lock signal, this signal exports this USB circuit for detecting 20 to by the USB line, after this USB circuit for detecting 20 detects this signal, transmit the signal to relatively decision circuitry 30 of logic, utilize BIOS Basic Input Output System again, Basic Input or Output System (BIOS)) POST Power On Self Test, Power-On Self-Test) function, analyze and comparison by 30 pairs of these signals of this logic comparison decision circuitry, judge whether this board 10 to be measured is in normal operating conditions, if this board 10 to be measured is in normal operating conditions, then this logic compares the signal of decision circuitry 30 outputs one board 10 operate as normal to be measured to status display interface circuit 40, make LED that green light is bright, export the one-period pulse simultaneously to this optical relay control circuit 50, and make this optical relay control circuit 50 conductings, thereby trigger the duty that USB circuit for detecting 20 continues this board 10 to be measured of monitoring; If this board 10 to be measured is in abnormal operating state, when promptly breaking down, this logic comparison decision circuitry 30 makes this optical relay control circuit 50 close, no longer control the duty that this USB circuit for detecting 20 continues this board 10 to be measured of monitoring, export board 10 out of order signals to be measured simultaneously to status display interface circuit 40, make LED that red light is bright, and be provided with the hummer sound that can give a warning, remind the tester to go to processing.
