A system capable of monitoring and controlling a number of pieces of electrical apparatus (16,18,20,22,24,26) within a region, comprises a base station (2) capable of communicating with at least one remote station (28), via a communication medium, each remote station (28) being associated with at least one piece of electrical apparatus (16,18,20,22,24,26) and further each remote station (28) comprising a local processing means capable of communicating with the base station (2), a monitoring means capable of monitoring a parameter of the electrical apparatus and producing an output signal representative of the parameter and communicating the output signal to the local processing means and a control means capable of controlling the electrical apparatus (16,18,20,22,24,26) upon receipt of signals from the local processing means wherein the communication medium is a bus (4) linking at least one remote station to the base station. This system is especially suitable for monitoring and controlling lighting within a tunnel. However, the system is capable of providing full environmental control within the tunnel. |
