ACCELERATION SENSOR WITH DATA PROCESSING SYSTEM OF AUTHENTICATION INFORMATION

摘要

PROBLEM TO BE SOLVED: To speed up and simplify the handling operation of authentication information by executing a means commanding the control of and supplying power to a data processing system of authentication information between an acceleration sensor and the data processing system of authentication information. SOLUTION: This processing system 1 supplies data on authentication information for the sensor side to an acceleration sensor 21 via a transformer 25 and is simultaneously supplied with power and control signals from a measuring device 9 via the acceleration 21. For supplying power to the processing system 1, output obtained from the measuring device 9 via the transformer 25 is rectified and stabled at a processing system power circuit. Control signals obtained from the measuring device 9 via a transformer on the processing system side are amplified, converted into digital data, and inputted to a processing system control circuit. This control circuit is formed of a microprocessor and an internal transmitter. Data inputted from EEPROM to the processing system control circuit is outputted to a transformer on the acceleration sensor side as the same tone burst waves as the control signals.
