MNCS Lab: A Mobile-Enabled Remote Laboratory Platform with Easy Integration of Control Experiment Units

Remotely accessible control system laboratories remain difficult to extend and administer, particularly when new experiment hardware must be integrated without disrupting an existing infrastructure. This paper presents two architectural contributions to Mobile Networked Control System (MNCS) Lab, a mobile-oriented remote laboratory platform. First, a Remote Laboratory Administration Server (RLAS) built on Laravel 12 and hosted at https://mncs.online handles user authentication, time-slot scheduling, and resource management through a REpresentational State Transfer (REST) Application Programming Interface (API). An integrated Progressive Web App (PWA) dashboard lets administrators configure and register new experiment units directly from the management interface. Second, the MNCS Gateway is a locally deployed server utility that connects any hardware or virtual instrument with a Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) port to the MNCS Lab platform, making it available under a dedicated public subdomain and validating every incoming command against RLAS-issued reservation tokens. The Air Bearing Spacecraft (ABS) platform at Harbin Institute of Technology, China (HIT) validates the efficacy of the system, confirming correct access enforcement, real-time command delivery, and closed-loop control through an Android-native Mobile Experiment Terminal (MET).
