Bench Test Support Application ExFlower

Easily automate complex tests using a flowchart method to improve testing efficiency.

In the field of automobile development, while testing is becoming more complex, there is a demand for increased efficiency in development.
ExFlower is a bench test support application designed to efficiently conduct increasingly complex tests using a flowchart method.
It can automate testing processes that could only be performed by human judgment until now, contributing to the reduction of on-site work and the prevention of human errors, allowing for easy and efficient testing.

Features

Create the details of the exam.

  • Free exam customization is possible with a flowchart.

  • Automation of various tests and control of various external devices is possible.

  • Create the details of the exam.

Create and execute the testing process.

  • It is possible to freely customize tests by selecting any subflow.

  • Temporary interruption processing during abnormal conditions is possible with interrupt flow.

  • Create and execute the testing process.

Create operations for abnormal situations.

  • Abnormal processing is possible through interruption flow.

  • Create operations for abnormal situations.
  • Features

  • Adoption of a flowchart method that allows for easy and flexible customization of various test automations.

  • The system consists of two independent applications: the SubFlow Editor (for test planning) and the MainFlow Editor (for test execution), which clarifies the division of labor.

  • Temporary interruption processing during abnormal conditions is possible with interrupt flow.

  • The debugging feature allows for the verification of the flow created before the actual test.

  • Autonomous driving that can collaborate with various external devices.

Ver2.7 New Features

  • Improve the synchronization of multiple driving instructions given all at once.

  • Enhancement of search and debugging functions, and efficiency improvement in verification tasks.

  • Enhance library functions

Ver.2.7 New Features

1. Multiple step instructions.

This feature improves the real-time nature of instructions, allowing for transitional test instructions and enabling the automation of drivability tests and shift shock tests.

  • conventional

Traditionally, instructions were given on a case-by-case basis from ExFlower.
Due to the operational status of the PC application and communication conditions, there may be delays in instructions, making it difficult to operate with time-sensitive instructions in a transitional manner.

  • multiple step instructions

A method to issue multiple step instructions at once
By issuing instructions together, it is possible to provide more accurate timing than before.

2. Enhance the variable search function and debugging function.

Improvement of the variable search function

The visibility of the existence and location of searched variables in the created flow has been made clearer.

Improvement of debugging functions

Make the debugging operation time variable, allowing for a reduction in debugging operation time.

3. Enhance library functions.

A new type has been added to the library function, making it even easier to reuse test flows that have been created once and to deploy them to other benches.
Additionally, it is now possible to incorporate IronPython libraries*, enabling collaboration and automation of operations beyond the application framework.

By loading the created library flow, it can be commonly utilized for various benchmark tests.

Integration with the IronPython library

With the built-in IronPython library*, it is possible to have high flexibility in external controls such as playing Wave files.

*Libraries confirmed to work: wave, winsound, subprocess, os

NV testing utilizing ExFlower

The utilization of ExFlower allows for easy integration of the Automatic Measurement Control System FAMS and the Sound and Vibration Analysis System O-Solution. While controlling the operation of the test specimen based on commands from ExFlower, noise and vibration measurements are automated, eliminating the hassle of operating each device.
