queuing system module

Our client is a manufacturing company. There are multiple loading bays and trucks will be waiting for their turn to load the finished goods. The parking area will be having 4 lanes with 4 outdoor display screens. The operating system is Tizen (for the displays). The client ERP will drop an XML file in a shared folder. The proposed application should read the XML file and display it on the monitor. The XML file will be having a truck number and the loading bay number. Once the truck is loaded, a new XML file will overwrite the existing file. The application will keep checking the folder every 5 seconds. If the work is completed and no more goods to load, the ERP will drop an XML file with no details. The proposed application should remove the ongoing display /shut down the screen. Timeline - ASAP
