Interoperability Testing & Debugging for an Automobile Company

August 28, 2023

Business Problem

A prominent automobile manufacturer faced challenges within their Internet of Things (IoT) setup at their manufacturing plant. This setup comprised diverse Zigbee sensors responsible for monitoring parameters like temperature, humidity, position, proximity, collision, and ultrasonic readings. These sensors utilized chipsets, adhering to the Zigbee 3.0 protocol. However, the client encountered multiple IoT-related issues, including performance bottlenecks, configuration complexities, and communication reliability concerns.

Business Analysis

The client’s manufacturing plant relied heavily on the accurate functioning of IoT systems to ensure smooth operations and maintain product quality. The identified issues were affecting overall efficiency and creating hurdles in the production process. The challenges spanned across performance degradation, difficulty in configuring sensors, and unreliable communication between devices.

PureSoftware Solution

PureSoftware formulated a comprehensive solution to tackle the client’s IoT challenges. The company established a dedicated testing and debugging laboratory, which closely emulated the conditions of the automobile manufacturing plant.

The team deployed Zigbee kits within the lab setup. This included creating a Zigbee mesh network, Zigbee to Wi-Fi gateway, control bridge, end devices, multiple coordinators, and integration of third-party sensors from various manufacturers. Network data was collected using a sniffer, enabling a thorough analysis of the network behavior. This facilitated the identification of root causes behind performance issues, configuration difficulties, and communication reliability problems.

PureSoftware incorporated software-based simulations of events, alarms, and control sequences involving Zigbee end devices, routers, and gateways. This allowed the team to assess the behavior of the system under different scenarios and identify potential problem areas.

The team utilized a debugged version of the Zigbee stack and made modifications to the stack image at the Physical (PHY) and Medium Access Control (MAC) layers. These alterations helped in diagnosing issues and proposing fixes for the stack. Every aspect of the customer documentation, including reference manuals, application notes, and user guides, was meticulously reviewed. The team re-ran tests, validated steps, and reported areas requiring improvement, contributing to enhance experience for users.

PureSoftware Result

Through the implementation of this comprehensive solution, PureSoftware successfully addressed the performance, configuration, and communication reliability challenges faced by the automobile manufacturer.

The dedicated lab setup allowed for in-depth testing and debugging, leading to accurate identification of issues and their subsequent resolution. By modifying and debugging the Zigbee stack, the team not only mitigated existing issues but also ensured improved future performance.

The documentation review and validation contributed to an enhanced user experience and streamlined operations within the IoT setup.

As a result of these efforts, the client experienced smoother manufacturing operations, improved product quality, and increased overall efficiency within their IoT-enabled manufacturing plant.
