Car rear box controller final inspection station

1.1.1 * Hardware system:

    Using today's advanced modular design, test equipment using imported intelligent instruments and special module testing, the use of computer centralized control system, the system more reliable, more convenient maintenance.

    PC is responsible for monitoring and management of the entire test system status and test data management, the next crew is responsible for data collection and process control.


1.1.2 * Software system:

Using WIN98 / WIN2000 / WIN NT operating system, the development of language using the United States NI Labview development, the system is very reliable.

    The software is powerful, easy to operate, the user automatically enters the test system after power on, exit automatically shut down, reduce the man-made operation error.

    The system includes five parts: automatic test, system configuration, data management, metrological identification and system maintenance.

    System automatic test is responsible for the car sunroof controller factory data collection, automatic judgment, a variety of alarm tips;

    System configuration is responsible for the car sunroof controller model settings, various types of test standards set;

    Data management is responsible for testing the statistical management of data and report printing can be the original product production data tracking;

    The measurement and verification is responsible for the measurement and calibration of all measuring instruments, so that the test data is more accurate; system maintenance has a systematic diagnostic function for system debugging, maintenance and maintenance to provide effective means.

    At the same time system design software user rights design, Barcode bar code control and test data preservation, to meet the traceability of quality requirements;



2.1.1 Main use

    (Hereinafter referred to as the test bench) is a set of customized automated test system, in the ECU factory test mode for its functional verification and performance parameters of testing, to meet the mass production process of product quality and quality testing The demand.


2.1.2 System functions

* This test bed implements all the items that have completed the FCT function test, including but not limited to the connector test, voltage acquisition, leakage current test, key input, switch input, Hall signal detection, fault detection, current detection and calibration, HALL voltage Detection, LED output detection, quiescent current, output control, analog detection (resistive load), fault diagnosis, error prevention (measured when the bad product downtime), power protection, self-protection, self-test, data backup , Server, ERP), data upload, ERP / MES system communication and other functions of the automated test.

* Provide all kinds of signals required for functional testing and ensure the corresponding signal accuracy.

* Provide power to the ECU and the required analog load.

* Check the analog output signal and ensure the inspection accuracy.

* Check the working status of the switch output circuit.

* The test bench has the ability to automatically test, automatically record data, automatically prompt the fault information.

* This test bench provides manual test function, you can manually add or test all functions.

* This test bench fixture with compatibility, compatible with the needs of different structural products, different structural products need to replace the fixture on the board, joints and other ancillary structure, no need to adjust the host hardware.

* This test bench is scalable.

 

The test bench consists of a test cabinet and a test fixture. The test cabinet and the test fixture are connected by a wire harness. The test cabinet is mainly used to install the test host, analog load, power supply, power protection and other equipment; test fixture for ECU and access ECU interface for testing.
