Development of a "mains borne" remote control system

Thesis (Masters Diploma (Technology)-- Cape Technikon, Cape Town, 1991Many environments employ time switches to control the operation of electrical machinery and appliances. These devices are generally expensive and require extensive wiring and individualised treatment. The need therefore arises for a more efficient and economical control system that will not be subjected to the limitations found in conventional remote control systems. This thesis describes a universal remote control system developed to suitably replace conventional systems prone to various limitations and restrictions. The system is "mains borne" and therefore makes use of the mains wiring for interconnectivity. The term "Mains borne" refers to the communicating medium interconnecting the various components
