Title:
TRANSMITTER-RECEIVER FOR WORK INTRINSIC DATA
Document Type and Number:
Japanese Patent JP3191588
Kind Code:
B2
Abstract:
PURPOSE: To remove an insulating membrane formed on a loaded lithium battery without shortening the battery life of a mobile communication device by using a microwave which is sent from a fixed communication device as a power source for a pulse current used for the aging process of the lithium battery.
CONSTITUTION: The fixed mobile communication device once detecting the arrival of a vehicle body with a limit switch, etc., provided for each operation stage sends the microwave having control data including a power transmission start signal to the mobile communication device 2. The mobile communication device 2 demodulates the microwave, received through a common antenna 8 and a receiving circuit part 221 dedicated to the microwave, into a digital signal by a demodulating circuit part 222. Then a CPU 211 stores and holds the electric power sent with this microwave in a capacitor circuit 232. Electric charges accumulated and held in the capacitor circuit part 232 are used to supply the pulse current to the lithium battery 231 as many times as specified and break the secondary membrane, thereby preventing a voltage delay phenomenon.
