Necessity of Platform

Platform is an environment that the system is running. It provides environment that can be edited according to business characteristics and users can use it in any form depending on any purpose.

When different applications are loaded on one platform due to differences in hardware and in products of inspecting function, it causes to a lot of maintenance loss.

When new functions are added, current application should be updated through the process of compile, moreover, it costs much of time consuming and loss of human labor by such as risk of history management, re-verification of reliability at each facility.

In addition, closed development environment of application that even user cannot edit ‘its Work Flow’ brings the result of bounding to the development company. The most common types of quality problems in the tester are mainly developer’s mistakes modified in the field rather than defects of equipment components.

Control System based on Platform

Based on the development know-how of performance and reliability tester of automotive electronic control units(ECU) since 2001, we have developed hardware distributed control system (model : PEP-6000 Series) for low cost and high efficiency from 2007, it is now available PEP-8000 Series with steady upgrade.

Control system with Embedded Operation System has self-synchronize timer based on hardware and is able to configure Real-time Measurement System using Data acquisition board(DAQ) and Motion control board.

Production EOL Line Testing system is designed to operate based on control system PEP-8000 series.

Platform of Performance and Reliability Tester

Based on embedded script engine and user-editable pattern scheduler, user can directly create and execute function list and DV Plan on the given environment. Performance and Reliability Tester is a testing equipments that determines whether ECU is abnormal in the case of executing environment test on ECU more than 1,000 hours.

Therefore, it can proceed load application and evaluation simultaneously using multi-threading. It also has error-tracking functions and every kind of analysis functions. Moreover, user can easily interlock with chamber by protocol which can control chambers.

Platform of Production EOL Line Tester

This platform is able to proceed bi-directional emergency messaging applied protocol for high speed data communication. It provides the development environment that determine the product’s conformity with embedded script engine and user editing function.

For Production EOL Line Testing systems, control system (PEP-8000 series) performs a vital role in testing because it tests the finished products. It includes motion-control functions using various PLCs and servo motors.

Furthermore, it is possible to allow flexible response by interlocking and monitoring functions to protect test equipment. It also provides functions counting production on a day, counting defective products and analyzing measured value of each item.

Expectation

The expected effects of applying the platform are as follows.

Application example

Our performance and reliability testers have been constantly supplied and used by Continental Automotive and Mando which are automotive parts developer and suppliers since 2002, and have been expanded global corporation in USA, India, Iran and China.

EOL (End of Line) Tester equipment have been continuously supplied in CEPS / REPS production line at Mando since 2012, which are planning to expand it to Global site.
