Abstract
PAZ PENAGOS, Hernán et al. Networking automation of ECIs G-204 electronic engineering laboratory. Ing. Investig. [online]. 2006, vol.26, n.3, pp.100-112. ISSN 0120-5609.
Increased use (by students and teachers) of the Escuela Colombiana de Ingeniería Julio Garavito Electronic Engineering laboratories during the last year has congested access to these laboratories; the Schools Electronic Engineering (Ecitronica) programmes applied Electronic studies centre research group thus proposed, designed and developed a research project taking advantage of G buildings electrical distribution to offer access facilities, laboratory equipment control, energy saving and improved service quality. The G-204 laboratorys network system will have an access control subsystem with client-main computer architecture. The latter consists of a user, schedule, group and work-bank database; the user is connected from any computer (client) to the main computer through Internet to reserve his/her turn at laboratory practice by selecting the schedule, group, work-bank, network type required (1Φ or 3Φ) and registering co-workers. Access to the G-204 laboratory on the day and time of practice is made by means of an intelligent card reader. Information of public interest produced and controlled by the main computer is displayed on three LCD screens located on one of G buildings second floor walls, as is an electronic clock. The G-204 laboratory temperature and time are continually updated. Work-banks are enabled or disabled by the main computer; the work banks are provided with power (beginning of practice) or disconnected (end of practice or due to eventualities) to protect the equipment, save energy, facilitate monitors and supervise the logistics of the state of the equipment at the end of each practice. The research group was organised into Transmission Line and Applications sub-groups. Power Line Communications PLC technology was used for to exploring digital modulation alternatives, coding and detecting errors, coupling, data transmission protocols and new applications, all based on channel estimation (networking) as the means of transmission.
