Abstract

가. 청구범위에 기재된 발명이 속한 기술분야.end. The technical field to which the invention described in the claims belongs.

디지탈데이타 수집장치Digital data collection device

나. 그 발명이 해결하려고 하는 기술과제I. The technical problem that the invention is trying to solve

종래의 여러 개의 주파수를 이용한 무선통신에 의한 디지탈데이타 수집장치는 송신장치의 갯수만큼 수신장치를 요구하므로 설치 및 비용이 부담스러운 단점과 여러개의 주파수의 혼동에 의해 정확한 데이타의 수집이 곤란한 것임.The conventional digital data collection device using wireless communication using multiple frequencies requires the receiver as many as the number of transmission devices, so it is difficult to collect data accurately due to the disadvantage of installation and cost and confusion of multiple frequencies.

다. 그 발명의 해결방법의 요지All. Summary of the Solution of the Invention

본 발명은 하나의 주파수를 사용하여 순차적으로 데이타를 수신부에 보내므로 주파수의 혼동을 방지하고, 하나의 수신부로도 디지탈데이타의 수집이 가능하도록 하는 것임.According to the present invention, data is sequentially transmitted to a receiver using one frequency, thereby preventing confusion of frequencies and enabling digital data to be collected by one receiver.
