Abstract
A kind of durable auto-inspection recorder of instrument is related to a kind of durable automatic detection recording technique of instrument, in order to solve the problems, such as to be difficult to by manually observing complete monitoring since the existing endurance quality detection test period is long.The host computer of the present invention is instructed for presetting pass the test threshold value, and for assigning feature；The feature command input that detection device occurs for signal is connected with the feature instruction output end of host computer；Signal occurs detection device detection signal output end and is connected with the detection signal input part of meters under test；Camera is used to acquire the characteristic information of meters under test, and feeds back to host computer；Host computer is compared to judge whether meters under test is qualified according to the characteristic information of feedback with default pass the test threshold value；If unqualified, host computer enables alarm send out alarm signal.It has the beneficial effect that the detection process of entire endurance test carries out continual acquisition and recording, uses manpower and material resources sparingly.
Description
Technical field
The present invention relates to a kind of durable automatic detection recording techniques of instrument.
Background technology
The type of increase with consumer to automobile individual demand, Automobile Digital combination instrument also emerges one after another,
But the overwhelming majority is all embodied in the placement of appearance and display device, and the type of gauge outfit does not change；Existing instrument on automobile
Include mainly speedometer, revolution counter, water-thermometer, fuel gauge, oil pressure gauge, air gauge and voltmeter.To these instrument
In endurance quality detection experiment, it is thus necessary to determine that the respective checking parameter of device；Wherein, endurance quality detection refers to being marked according to experiment
During which standard, a kind of test to instrument stability in use, the uninterrupted operation of generally contiguous a few days or even some months use people
The mode of work observation not only arduously, but also is difficult whole process supervision.
Invention content
It is difficult to by artificial the purpose of the present invention is to solve long due to the existing endurance quality detection test period
A kind of the problem of observing complete monitoring, it is proposed that durable auto-inspection recorder of instrument.
The durable auto-inspection recorder of a kind of instrument of the present invention includes that host computer, alarm, signal detect
Device and camera；
The host computer is instructed for presetting pass the test threshold value, and for assigning feature；
The feature command input that detection device occurs for the signal is connected with the feature instruction output end of host computer；
The signal occurs detection device detection signal output end and is connected with the detection signal input part of meters under test；
The camera is used to acquire the characteristic information of meters under test, and feeds back to host computer；
Host computer is compared whether judge meters under test according to the characteristic information of feedback with default pass the test threshold value
It is qualified；If unqualified, host computer enables alarm send out alarm signal.
The present invention the course of work be：By signal occur detection device and meters under test, signal generation detection device with it is upper
Position machine, camera and host computer and host computer and alarm connect, and start working power；It is closed by the default experiment of host computer
Lattice threshold value simultaneously assigns feature instruction, and control signal occurs detection device and sends detection signal, meters under test to meters under test first
After receiving detection signal, pointer will appear variation, which is captured by camera, and with the shape of characteristic information
Formula is sent to host computer；Host computer is by the comparison of the characteristic information received and default pass the test threshold value, if host computer is sentenced
After determining meters under test durability degree qualification, host computer stores its Test Information；If host computer judges that meters under test is durable
Spend unqualified, host computer equally stores its Test Information, and sends alarm signal to alarm, and alarm is according to report
Alert signal gives a warning.
After setting default pass the test threshold value by host computer, by host computer and with letter
Number detection device communication, correction data, in testing result exception and alarm occurs；Detection device occurs for signal using list
Piece machine technology, can send the signal of instrument needs, while by the characteristic value of cam feedback, feed back to host computer, to whole
The detection process of a endurance test carries out continual acquisition and recording；Entire recording device, both can be complete by entire detection process
Complete record can also use manpower and material resources sparingly in the abnormal alarm of detection.

In the present embodiment, by signal occur detection device 3 and meters under test 5, signal generation detection device 3 with it is upper
Machine 1, camera 4 and host computer 1 and host computer 1 are connected with alarm 2, start working power；Pass through the default examination of host computer 1
It tests qualified threshold value and assigns feature instruction, control signal occurs detection device 3 and sends detection signal to meters under test 5 first, waits for
After survey instrument 5 receives detection signal, pointer will appear variation, which is captured by camera 4, and with feature
The form of information is sent to host computer 1；Host computer 1 is by the comparison of the characteristic information received and default pass the test threshold value, such as
After fruit host computer 1 judges 5 durability degree qualification of meters under test, host computer 1 stores its Test Information；If host computer 1 is sentenced
Determine that 5 durability degree of meters under test is unqualified, and host computer 1 equally stores its Test Information, and sends alarm signal to reporting
Alert device 2, alarm 2 give a warning according to alarm signal.
Specific implementation mode two：Present embodiment is to the durable automatic detection of a kind of instrument described in specific implementation mode one
Recorder further limits, and in the present embodiment, host computer 1 occurs detection device 3 with signal and connected by CAN bus
It connects.
Specific implementation mode three：Present embodiment is durable to a kind of instrument described in specific implementation mode one or two automatic
Detection recorder further limits, and in the present embodiment, detection device 3, which occurs, for signal is carried out with meters under test 5 by harness
