Abstract
The utility model relates to an automobile part, and particularly relates to an aging detection system for automobile air-conditioner controllers. The aging detection system comprises a plurality of detection devices used for detecting aging states of the air-conditioner controllers, wherein each air-conditioner controller is loaded with a simulated load, each simulated load and each detection device are connected with an aging controller, and the aging controller is connected with a computer. The aging detection system provided by the utility model is capable of enabling data acquisition and data analysis of aging states of the air-conditioner controller to be intelligentized, improves the level and the precision of automobile air-conditioner controller detection while ensuring the health of technical workers, and simplifies working procedures of the detection under the premise of reducing the cost; and what is more important is that the aging detection system can detect a large number of automobile air-conditioner controllers simultaneously, and the data recorded by the computer can also be used as a reference for fault analysis in the future.
Description
Technical field
The utility model relates to auto parts machinery, is the aging detection system of automotive air-conditioning controller specifically.
Background technology
Automotive air-conditioning controller is critical components of Control of Automobile air-conditioning system as a kind of automobile electronics.Its function mainly is the sensor signal of gathering air-conditioning system, and equipment such as control air door, fan blower, compressor provide man machine operation interface simultaneously.The difference of automobile electronics and normal domestic electronic product is the working environment more complicated, and quality requirements is than higher simultaneously, and this has just proposed to compare higher requirement to exploitation, production and the check of automobile electronics.
Possibly there is latent defect in automotive air-conditioning controller when manufacturing; As silicon chip surface pollute, tissue is unstable, welding cavity, chip and shell thermal resistance coupling are bad etc., and defective can not use the general test means to find; So need apply thermal stress to it; Latent fault is occurred in advance, make product as early as possible, get into highly reliable stationary phase through the bathtub characteristic initial stage that lost efficacy.At present the main flow mode is that the technician gets into burn-in chamber and carries out manual operations; The rugged surroundings of burn-in chamber are unfavorable for personnel's health so on the one hand; The working condition of temperature controlling, automotive air-conditioning controller can't be accomplished real-time control in the room on the other hand; Accuracy of detection is low, and labour intensity is big simultaneously, and can't detect a large amount of automotive air-conditioning controllers simultaneously.
The utility model content
The utility model has solved above-mentioned technical matters, provides a kind of automotive air-conditioning controller easy to operate, that can detect a plurality of automotive air-conditioning controller ageing states simultaneously aging detection system.
The technical scheme that the utility model solves the problems of the technologies described above employing is: the automotive air-conditioning controller detection system that wears out; Comprise that several detect the pick-up unit of air-conditioner controller ageing state; Be loaded with a fictitious load on each said air-conditioner controller; Each said fictitious load all is connected with an aging controller with pick-up unit, and said aging controller links to each other with computing machine.
Can know from above technical scheme; The utility model can be intelligent with collection, the data analysis of automotive air-conditioning controller ageing state data; Guarantee that the technician also promotes the level and the precision of automotive air-conditioning controller check in the time of healthy, simplified the test job flow process under the prerequisite that reduces cost; The more important thing is that this system can detect a large amount of automotive air-conditioning controllers simultaneously, the data of its computer recording also can be used as the reference of analysis of failure from now on.
Description of drawings
Fig. 1 is the structured flowchart of a kind of optimal way of the utility model.
Embodiment
Specify the utility model below in conjunction with Fig. 1:
The described automotive air-conditioning controller of the utility model detection system that wears out; It comprises that several detect the pick-up unit 2 of air-conditioner controller 1 ageing state; Be loaded with a fictitious load 3 on each said air-conditioner controller 1; Each said fictitious load all is connected with an aging controller 4 with pick-up unit, and said aging controller links to each other with computing machine 5.In the utility model, adopt high-power resistance as fictitious load, output loads such as analog DC motor, relay, high-power MOS tube.Owing to be to carry out high temperature ageing, the operator can not observe it for a long time, and the fault part possibly recover normally at normal temperatures, so this detection system can adopt automatic detection device that several automotive air-conditioning controllers are detected automatically.
In the course of the work, the technician can control aging controller on computers.Pick-up unit carries out communication by aging controller to the aging automotive air-conditioning controller of switching on after starting, and sends instruction to it, and automotive air-conditioning controller is received the instruction back and got into ageing state; Simultaneously, aging controller is sent to computing machine through pick-up unit with failure message, carries out record automatically by it.After digestion time arrived, the technician can stop aging the detection through aging controller, and according to the failure logging of preserving on the computing machine, judges failure cause.The utility model can be intelligent with collection, the data analysis of automotive air-conditioning controller ageing state data; Guarantee that the technician also promotes the level and the precision of automotive air-conditioning controller check in the time of healthy, simplified the test job flow process under the prerequisite that reduces cost; The more important thing is that this system can detect a large amount of automotive air-conditioning controllers simultaneously, the data of its computer recording also can be used as the reference of analysis of failure from now on.
Above-mentioned embodiment only supplies to explain the usefulness of the utility model; And be not to be the restriction to the utility model; The those of ordinary skill in relevant technologies field; Under the situation that does not break away from the utility model spirit and scope, can also make various variations and modification, so all technical schemes that are equal to also should belong to the category of the utility model.
