Abstract

With the rapid expansion of tunnel infrastructure and increasingly stringent safety regulations, the calibration accuracy of carbon monoxide (CO) detectors has become a critical component of transportation safety systems. Traditional manual calibration methods face limitations in efficiency, cost, and environmental adaptability, prompting the rise of remote calibration technologies known for their non-contact, intelligent, and efficient features. This study focuses on the development of remote calibration systems for tunnel-based CO detectors and analyzes three representative technical approaches: an integrated system combining flexible gas containers and remote control mechanisms, a portable modular toolkit optimized for on-site adaptability, and a pose-sensing actuator system that restores physical calibration operations remotely. From the perspectives of structural design, workflow execution, error control, and system scalability, this paper verifies the practical feasibility and engineering adaptability of remote calibration under complex tunnel conditions. The results indicate that with integrated hardware-software systems and platform-based management, remote calibration will play an increasingly vital role in intelligent maintenance and carbon monoxide monitoring within smart transportation frameworks.
