ABSTRACT:
In managing an underground facility, considering the enormous number of documents, the number of people who are involved with the management of electric power, communication, gas, water, sewage or the like, and expended hours, enormous cost and time have been needed so far. A wireless chip is attached to each buried object itself in substitution for a boundary stake or a display stake of an underground facility or a ground facility. Then, data such as embedded date, position data, or an owner is written into a memory portion of the wireless chip. In addition, by incorporating a CUP in the wireless chip, only a terminal having an encryption function which has obtained permission of communication can communicate, and access by unspecified number of devices, leakage of position data or the like, an erasure of stored data, rewriting, and the like can be prevented. Such a system can surely perform management of facility data.
