Abstract:
1. A data logging and transmitting device that includes more than one communication device, an instruction list stored in the data logging and transmitting device, one or more input ports, one or more output ports, one or more data buffers and one or more processing units; wherein in use: (a) said data logging and transmitting device collects, processes and forwards data and/or one or more predetermined signals to two or more independent external locations; (b) the or each input port is connected to one or more data collection devices, the or each data collection device measuring or recording one or more parameter of the environment or equipment which is being monitored; (c) the or each input port being connected to one or more data buffers, the or each data buffer storing data received from the data collection device; (d) the or each processing unit reads the data stored in the or each data buffer and processes it according to the instruction list generating one or more data streams; (e) the or each data stream is independently transmitted to said two or more independent external locations and zero or more said output ports; (f) the data stream is independently transmitted to each of said two or more independent external locations using one or more of more than one communication device, the or each communication device used, and/or frequency used by the or each said communication device, being determined by the instruction list; (g) if the or each communication device chosen in step (f) is not available to, or cannot reliably, transmit the data stream to one or more remaining external location, said remaining external location being one or more external location that has not yet successfully received the data stream, then a next communication device or next frequency, is used to transmit the data stream to the or each remaining external location, the or each next communication device, or next frequency, being determined by the instruction list; (h) if the or each next communication device, or next frequency, chosen in step (g) is not available to, or cannot reliably, transmit the data stream to the or each remaining external location then a further next communication device, or next frequency, is used to transmit the data stream to the or each remaining external location, the or each next communication device, or next frequency, being determined by the instruction list; in all cases the instruction list includes at least two communication devices to be selected from, and where each of said at least two or more independent external locations does not merely act as a relay to another external location specified in the instruction list.
