Title:
Advanced Python Developer for IoT System Refactoring and Enhancement
Project Overview:
We are looking for an experienced Python developer to take on the challenge of refactoring and enhancing an existing industrial IoT system used for water treatment monitoring. The system is currently built on a monolithic architecture and tightly coupled with Thingsboard IoT platform. It handles a multitude of tasks including sensor data collection, actuator control, and data telemetry.
Current Structure:
The codebase is a single, extensive script that has grown over time, leading to complexity and maintainability issues.
Global variables are used extensively for configuration and state management.
Sensor and actuator integration is hardcoded, requiring significant manual code changes for each new device.
Data is transmitted to Thingsboard in a fixed interval, resulting in high network traffic.
The system uses a custom Modbus library for sensor communication via RS485, which needs updating to align with the new architecture.
Refactoring Goals:
Modularize the codebase into logical units:
A dedicated module for Thingsboard communication.
Separate scripts for different sensor and actuator types.
A configuration management system to handle system settings and state.
Implement a plug-and-play mechanism for sensors and actuators that supports easy integration and scalability.
Optimize data transmission to Thingsboard to reduce network load by implementing a dynamic interval system based on the importance and change rate of each data point.
Enhance the timer logic for more robust and flexible scheduling of tasks.
Update and standardize the custom Modbus library for better compatibility and maintenance.
Responsibilities:
Analyze the current codebase to identify refactoring opportunities.
Design and implement a modular architecture that separates concerns and enhances code reusability.
Develop a configuration management system that simplifies the handling of global variables and system states.
Create an extensible sensor/actuator integration framework that minimizes the effort required to add new devices.
Design a data transmission strategy that intelligently schedules telemetry data to Thingsboard, balancing the need for timely information with network resource conservation.
Rework the timer mechanisms to be more intuitive and maintainable.
Update the Modbus library to ensure robust communication with various sensors over RS485.
Write comprehensive documentation to support future development and maintenance.
Qualifications:
Proven track record with Python and IoT systems.
Strong experience with MQTT protocol and Thingsboard platform.
Expertise in Modbus protocol, particularly over RS485.
Familiarity with industrial sensors and actuators.
Solid understanding of best practices in software architecture and design patterns.
Ability to write clean, maintainable, and well-documented code.
