System and method for real-time tracking of objects

摘要

Real-time location systems and methods use small, battery operated sensors and radios. The radios conform to the IEEE 802.15.4 standard. The radios are attached to objects to form mobile nodes. Fixed nodes are positioned to define a wired or wireless mesh network representing an area in which the objects can be monitored and tracked. The real-time location systems/methods provide robust, flexible and highly scalable systems/methods for remotely, accurately, efficiently, and/or readily tracking and securing objects (e.g., equipment, inventory, people) at a relatively low cost.

1. A method for installing a liner including a resin in a pipe situated below ground, the method comprising:
affixing a plurality of mobile tags along a length of the liner; positioning the liner within the pipe; applying energy to the liner to cure the resin such that the liner is bonded to the pipe; using a sensing network situated above ground to obtain localized temperature measurements from each of the mobile tags within the pipe at approximately the same time during application of the energy to the liner; and using the localized temperature measurements to control application of the energy along the length of the liner.
