Research and Implementation of Terminal Emulation of PTTE-IoT

Abstract

With the development of Internet of Things for power transmission and transformation equipment (PTTE-IoT), there is an increasing demand for protocol conformance tests. Terminal emulation is used in protocol tests, which improves the reliability of protocol tests while reducing costs. In the paper, terminal emulation is studied through researching and summarizing various PTTE-IoT terminal business behaviors and network characteristics. A terminal emulation scheme is realized, in which more than 50 terminals of multiple types can be emulated while the validity of test results is improved. The scheme is deployed in over 25 protocol conformance test cases, which verified the effectiveness of the scheme. In addition, the framework of the scheme can also be applied to other TDMA network test scenarios.
