Abstract
The invention discloses an intelligent test method for a wiring harness and belongs to the field of product test. A test system comprises a PLC (Programmable Logic Controller) unit, a switching value input/output module and a real-time on-line monitoring unit, wherein one end of the wiring harness is connected with a switching value output module of the PLC while the other end is connected with a switching value input module of the PLC; after passing through the wiring harness, a high level signal sent by the switching value output module under the control of the PLC is collected by the switching value input module; a signal is outputted to one end of the wiring harness by the switching value output module under the control of the PLC; the signal at the other end of the tested wiring harness is collected by the switching value input module; the judgment for the wiring harness test is completed by software; and a test result is displayed by a human-computer interface. Various types of the wiring harness can be preset in the software and can be intelligently identified and automatically selected and switched. The intelligent test method for the wiring harness has the advantages that a test instrument is simple in structure and convenient in operation; the wiring harness is quickly and accurately tested; the quality of the product is ensured; and the cost is lowered.
Description
Technical field
The present invention relates to a kind of intelligent test method and equipment of wire harness, belong to the product detection range.
Background technology
After wire harness was meant the contact element terminal crimping that the multiple conducting wires cable forms via the copper material punching out, the outside is the assembly of a kind of CC of forming of plastic compression insulator (like plastics, rubber etc.) or added metal housing again.In current each electric field, little of small household appliances, mobile phone, instrument, in automobile, aircraft or army's industry equipment, all need use wire harness greatly.Increase along with device upgrade makes functions of the equipments, the wire harness that uses in the equipment is day by day complicated.Safe and reliable in order to guarantee wire harness, must carry out conduction detection to wire harness.Generally, the union line of wire harness connector is many, detect relatively also more complicated, and present many wire harness connectors all is through manual detection, and detection efficiency is relatively slow, and has increased labour's cost, should not produce in enormous quantities.
The invention discloses a kind of intelligent test method of wire harness, for the inside connection situation that detects wire harness has accurately and rapidly been created condition.
Summary of the invention
Slowly wait problem in order to solve omission, false retrieval and the efficient that manual detection exists, the present invention provide a kind of simple in structure, easy to operate, detect wire harness tester accurately.During test, PLC CS amount output module adds a high level signal successively at the wire harness input end, gathers the level signal of wire harness output terminal through switching input module; Wire harness input endpoint and corresponding wire harness exit point conducting when the signal of gathering is high level; When the signal of gathering is opened a way during for low level; If low when high during level, then loose contact.
In order to realize above-mentioned functions, the detection system that the present invention adopts mainly is made up of PLC control module, switching value input/output module and real time and on line monitoring unit.
The PLC control module is gathered the signal of wire harness to be detected through the control signal input/output module, through accomplishing wire harness model discrimination and the analysis that is connected situation in the software.
Wire harness one end links to each other with the switching value output module of PLC, and the wire harness other end links to each other with the switching input module of PLC.High level signal that PLC CS amount output module sends through behind the wire harness by the switching input module collection.
The real time and on line monitoring unit is made up of man-machine monitoring interface and alarm.
Description of drawings
Fig. 1 is the system diagram of the intelligent test system of wire harness.
Fig. 2 is the process flow diagram of the intelligent test system of wire harness.
Embodiment
Further specify below in conjunction with the accompanying drawing specific embodiments of the invention.
As signal input part, each end points is designated as I with an end of wire harness
i(i=1,2,3 ..., n); The signal output terminal of the other end, each end points is designated as O
i(i=1,2,3 ..., m), n and m possibly not wait.In PLC, preset corresponding wire harness corresponding input/output relation tables of data when qualified according to the wire harness model.
System brings into operation, and the user selects " the wire harness model of detection " or differentiates model automatically with a qualified wire harness test back through man-machine interface, after selecting to finish, and the trace routine that the PLC software transfer is corresponding.PLC software control output and load module are carried out data output and are gathered, and accomplish data analysis.
Concrete testing process: during test, PLC software control switch amount output module i end points of wire harness input end (i=1,2,3 ..., n) add a high level signal successively, gather wire harness output terminal O through switching input module
j(j=1,2,3 ..., level signal m); I input endpoint I of wire harness when the signal of gathering is high level
iWith corresponding wire harness exit point O
jConducting; Open a way during for low level; If low when high during level, then loose contact.
PLC is shown to result's output on the man-machine interface after analyzing data (promptly comparing with preset input/output relation tables of data) after the circulation.When undesired connection occurring, system can give the alarm and show the terminal number of wrong.
More than being preferred embodiment of the present invention, is not that the present invention is done any pro forma restriction, and every foundation technical spirit of the present invention all belongs in the scope of inventing technical scheme any simple modification, equivalent variations and modification that above embodiment did.
Claims (3)
1. the intelligent test method of a wire harness is characterized in that, during test, PLC software control switch amount output module i end points of wire harness input end (i=1,2,3 ..., n) add a high level signal successively, gather wire harness output terminal O through switching input module
j(j=1,2,3 ..., level signal m); When the signal of gathering shows i input endpoint I of wire harness during for high level
iWith corresponding wire harness exit point O
jConducting; Show between the terminal during for low level and open a way; If low when high during level, then show loose contact between the terminal.
2. according to the intelligent test method of the said wire harness of claim 1, it is characterized in that, in PLC, preset corresponding wire harness corresponding input/output relation tables of data when qualified according to the wire harness model.Accomplish the terminal number that PLC software analysis data after the circulation (promptly with preset input/output relation tables of data relatively) back is judged the qualified situation of wire harness and shown wrong.
3. according to the intelligent test method of the said wire harness of claim 1, it is characterized in that, predeterminable multiple wire harness type in the PLC software, intelligent distinguishing wire harness type is also selected to switch automatically.
