摘要

PURPOSE: A system for alarming position information on a member by using LAN communication and a method therefor are provided to extract information on an alarm display from a memory, so that the alarm display can be displayed according to the extracted information, thereby informing a member located within a building that a member located out of the building is located within a certain radius. CONSTITUTION: An alarm display(12) is distinctively set according to each member display by corresponding to the number of members. A memory(14) stores identifier information of an alarming device(10) and identifier information on the members. A transmitter/receiver portion(16) transmits the stored identifier information through LAN communication, and receives the identifier information of the members from a transmitter/receiver portion(24) of a mobile body(20). An alarm display controller(18) extracts information on the alarm display(12) from the memory(14), and enables the alarm display(12) to be displayed according to the extracted information.
