SafeTool
Implementering av RFID-teknologi i maskiner för byggbranschen
Every year more than 6000 thefts, to a value of 1.5 billion SEK, are reportedwithin the Swedish building trade. Plus all the indirect costs of having theconstruction site standing still.SafeTool is a newly started company that will try to prevent this problem witha modern technology solution.The key to SafeTool?s solution is RFID ? Radio Frequency Identification ? andthe solution looks like this;All tools are stored in a container on the construction site. Every tool isequipped with a RFID-tag that uniquely identifies the tool. With antennas in thecontainer it is possible to detect when a tool is leaving the container and whenit comes back. Every worker must wear a RFID-tag so it will be possible to seewho was taking the tool out of the container. The container has no externallocks on it, but the RFID-tag works as a key. An antenna on the roof of thecontainer identifies the worker and automatically unlocks the door.All the tool and personnel traffic through the door of the container are reportedto a central server via GPRS. The server stores all info in a database. Theadministration of the system will be done through a website.This paper will show how we made this solution work in practice. How wecreated and programmed the client and server and the protocol that makes themunderstand each other.
