一般的无线对讲机是单向同频工作的,其特点是发射机与接收机交替工作。即发话时不能收话,收话时不能发话。这样的通信方式不符合人们的谈话习惯,还容易造成漏话。本文向大家介绍的双向红外线光对讲机是接收机和发射机同时工作,发话、收话互不影响,操作也非常简便。不用光纤或光缆连接进行短距离光通信,通话距离在20米之内,可作学校的现代化通信教具;如低功率红外线通过特制的红外线发射器,则传播距离可达100米以上,可用于飞机中工作人员之间互相联络,又不会干扰飞机与陆地之间的
General wireless walkie-talkie is one-way with the frequency of work, which is characterized by the transmitter and receiver alternately. That is, can not receive a speech when speaking, can not speak when receiving a speech. Such communication does not meet people’s habits of conversation, but also easily lead to missed calls. This article introduces the two-way infrared light walkie-talkie receiver and transmitter at the same time, speaking, receiving each other’s influence, the operation is also very simple. Without optical fiber or cable connection for short-distance optical communication, call distance within 20 meters, can be used as a school of modern communication aids; such as low-power infrared infrared transmitter through a special, the propagation distance of up to 100 meters, can be used for aircraft In the inter-contact between staff, and will not interfere with the aircraft and land
