PHS TERMINAL EQUIPMENT AND DATA COLLECTION SYSTEM USING THE SAME

Japanese Patent JP3308837

B2

PROBLEM TO BE SOLVED: To inexpensively perform a collection and analysis of data without loading excess load to a center equipment by succeeding and transmitting data, which are generated by plural data generators, to the center equipment, while selecting any optimum route for more surely transmitting the data between PHS(personal handy system) terminal equipment.
SOLUTION: A PHS terminal equipment A-E loaded on plural automatic vending machines is communicated and connected through a public line network to the host computer of a business office, while defining A as a master equipment and B-E as a slave terminal equipment. At the PHS terminal equipment A-E, its storage part stores an entry table for management and a connection table to which electric field strength levels measured between the respective pieces of equipment are inputted. While these respective tables are in use, the transmission of data is executed by selecting the optimum transmission route of high numerical value which expresses certainty of data transmission among the PHS terminal equipment A-E. Thus, the business office can inexpensively collect data by reducing the load of its own equipment, while using the data throughput of respective PHS terminal equipment.
