Data transmission system and wearable communications device
First Claim
1. A data transmission system comprising:
- a master unit; and
a plurality of slave for wirelessly transmitting transmission data to the master unit under TDMA scheme, wherein each of the slave units includes communications means for performing signal transmission and reception with the master unit, and control means for setting, when the communications means does not detect a predetermined signal longer than a predetermined length of time, an own communications channel within the predetermined length of time in a frame to transmit transmission data to the master unit using the communications channel.

Abstract
To prevent process centralization to a master unit at the time of communications channel setting to slave units. Included are: a plurality of biometric information detection devices for detecting biometric information about attaching body such as heartbeat, and wirelessly transmitting corresponding biometric data; biometric information processing device for receiving the biometric data from each of the biometric information detection devices., and going through various types of processes such as a display process; and an information processing unit for receiving the biometric data of the biometric information detection devices from the biometric information processing device via a transmission/reception section. The biometric information detection devices determine their own communications channels, and transmit the biometric data to the biometric information processing device.
