Identification registration for a wireless transmission-reception control system
First Claim
1. A wireless transmission-reception control system comprising:
- a plurality of wireless transmitters respectively transmitting radio waves including transmission data including, for each transmitter, a unique ID code; and
a wireless receiver for receiving of radio waves, the wireless receiver including mode switching means for automatically switching an operating state of the wireless receiver between a registering mode for registering the ID codes in received radio waves and a normal mode for processing the transmission data, the mode switching means including;
start switch means for switching the wireless receiver into the registering mode in response to reception of radio waves from one of the plurality of wireless transmitters, anda retriggerable timer circuit activated by the start switch means for maintaining the wireless receiver in the registering mode for a predetermined time period and for automatically switching the wireless receiver to the normal mode after the predetermined time period elapses wherein the predetermined time period is restarted upon the registering of each unique ID.

Abstract
A wireless transmission-reception control system in which the data transmitted as a radio wave from more than one wireless transmitter along with an ID code are received by a wireless receiver and decoded at a front end decoder. The ID code of the transmitted data thus received is compared by a comparer with the ID code of the transmitted data already registered at a data register to discriminate if a collation of the data is to be made [or not], and only the transmitted data, the registration of which is confirmed, are decoded to have an output generated. The wireless transmitters each have different, fixed ID codes, and the wireless receiver may be switched over at least between a mode of registering an ID code and a mode of generating an output after the decoding of the transmitted data.
