Operational Control for Construction Tramcars
Problems: A company wants to automate the control of tramcars that are used to transport machinery and materials for tunnel construction and other works, in order to increase worker safety and improve the work environment. It is difficult to determine the present location and destination of the tramcars using a control system of only wireless devices and sensors. Mount an Antenna to the tramcar, and connect it to the equipment for controlling the tramcar operation (programmable controller, wireless device, etc.). Position an ID Tag at each point along the track where control is required. Write the basic position information into each ID Tag. The tramcar can then run automatically (stop, slow down, branch, etc.) according to instructions issued from above ground by wireless communications, while reading the data in the ID Tags.
