Abstract:
A telemetry system for measuring one or more parameters within a transport container and transmitting a signal indicating the value or values of the one or more measured parameters, or the status of the respective transport container, over a significant distance via at least one communications network, the system comprising:a) a receiving station connected to the communications network; b) monitoring means for receiving the signal and indicating the value or any one of the values represented by the signal, or the transport container status; and c) a mobile monitoring sub-system mounted on or within the transport container comprising: i) parameter measurement means to measure the respective parameters; ii) signal generating means to generate a signal for transmission indicating the value or values of the one or more measured parameters, or a status of the transport container, wherein the signal generating means holds data tolerance information in relation to the respective transport container and, when the signal generated by the signal generating means is to be transmitted, the signal generating means examines the value or values of the one or more measured parameters and if they are in tolerance, generates a status signal indicating that the system is operating correctly and all parameters are in tolerance and if they are not in tolerance, the signal generating means generates the signal representing the value or values of the one or more measured parameters; and iii) local communication means for transmitting the signal via the at least one communications network to the receiving station and the monitoring means.
