Title: Slave machine terminal, monitoring system, and radio transmission method
Inventor: KURIMOTO MASARU
IPC: A01K29/00
Filed: 2020-10-02
Abstract: To provide a technology capable of avoiding interference with less required labor and time and less power consumption than before.SOLUTION: Use of a plurality of slave machine terminals 20 makes state data D1 on a plurality of cows 10 be transmitted at fixed intervals, which makes it possible to monitor variations in states of the plurality of cows 10 in a lump.

Thereby, even if transmission timing deviation is not set previously to the plurality of slave machine terminals 20, repetition of transmission by all of the slave machine terminals 20 gradually establishes scheduling so that mutual overlap of transmission timing is eliminated.SELECTED DRAWING: Figure 3
