WIRELESS SIGNAL TRANSMISSION SYSTEM

摘要

PURPOSE:To improve the reliability of wireless signal transmission in response to the system by transmitting a data from a slave equipment to a master equipment intermittently in response to an output of a timer means from which a timer time is set properly. CONSTITUTION:When a sensor output takes place, the real timecast is given in response to the leading and trailing of the sensor output. Then periodic timecast is applied periodically based on the timer time properly set by a timer means in addition to the real timecast. That is, when a sensor output is generated at a point of time of the periodic timecast, a periodic timecast data (C) representing the production of the sensor output is sent and when no sensor output is produced, a periodic timecast data (D) representing the absence of the sensor output is sent in addition to the real timecast.
