TTS Test System

TOSUN's TTS test system integrates all the circuit components required to connect I/O channels into a single module, which can greatly simplify the setup of test benches and HIL test systems, and improve the efficiency of building and testing.

The TTS system is based on TSMaster, which realizes the integration of TTS chassis, supporting instrumentation, diagnostics and calibration on the software side, and realizes the single system covering the testing requirements in the development of on-board ECUs.

tts TSMaster Test System Framework

TSMaster Test System Framework

The systematic solution of TTS is realized through the test system architecture of TSMaster. In it, TTS maps the resources provided by TTS, such as AI, AO, DI, DO, etc., to system variables through a mapping layer, together with the calibration module, diagnostic module, and RBS module, as part of the TSMaster test system architecture.

tts Application Layer Perspective

Application Layer Perspective

  1. The test logic is decoupled, not tied to a database, not tied to specific instrumentation or boards. The system variable layer and the logic layer above the variable layer are detached from the physical logic layer. Therefore, the upper application layer does not need to be changed after the development and debugging is completed.
    When the following changes occur in the lower levels, the following adjustments are made:
    1. If the ECU corresponds to a database upgrade, the database is reloaded and the signal mapping module is adjusted.
    2. If the A2L changes, reload the A2L file. If the signal name changes, adjust the mapping name.
    3. The chassis hardware or wiring form has changed, just load the corresponding mapping configuration.

    No changes are made to the upper logic layer after the adjustment is complete.

  2. High accessibility of internal resources, scalability. Through the mapping layer, all hardware devices, software resources, etc. are mapped to system variables. Based on the system variables, internal test system, panel and other modules can access internal resources, and local (non-local) external processes can also access internal resources through RPC and COM.
  3. Provide the simplest call logic to the upper layer, test cases can be realized by using sequential call logic in most scenarios.

Problems that may be encountered with the use of board-based systems?

A: The high and low level judgment thresholds of the digital inputs may be affected under high load and long term use. We recommend periodic testing and calibration to ensure the stability and accuracy of the sampling cycle.
A: The digital outputs' voltage values at high and low levels and command response times may deviate slightly due to long-term use, which is one of the issues to be aware of in long-term testing. Our system is designed to minimize these deviations as much as possible.
A: The analog inputs may deviate in value over long periods of time, but our system is designed to minimize this and ensure a stable sampling period.
A: The accuracy of the analog outputs may be compromised after extended use, especially in terms of command response time. Periodic calibration is recommended to ensure accuracy.
A: In fault injection testing, the resistance factor and response time of the interference path are critical. TTS systems are designed to precisely manage these parameters to ensure the accuracy and reliability of the interference test.
A: Channel corruption can lead to test case failures, especially with a large number of channel types and numbers, and troubleshooting the problem can become more challenging. The TTS system provides tools to help quickly troubleshoot and repair failures.
