Tourist communication device and its communication method

Abstract

This invention discloses a tourist communication device and its communication method including an emit device and multiple receive devices characterizing that the emit device includes a first programmable IC chip, a signal generation circuit, a first RF circuit chip and a first antenna, the receive device includes a second programmable IC chip, a second RF chip, an audio amplifying circuit and a second antenna, among which, the audio amplifying circuit is connected with the earphone, signals generated from the signal generation circuit carry out phonetic signal collection by the first programmable IC chip mode number conversion circuit to send radio wave signals via the first antenna, the mode number conversion circuit of the second IC chip converts the radio wave signals received by the second antenna to analog signals to be output to the earphone via an audio amplifying circuit, the emit device is set with a frequency point selection designing unit.

Description

technical field [0001] The invention relates to a tour guide device, in particular to a tour guide communication device and a communication method thereof. Background technique [0002] Existing communication tour guide device is to solve the tour guide's explanation to tourists and contact with tourists at the scenic spot when traveling, as No. 94214888.6 Chinese utility model patent of the announcement authorization on May 31, 1995 discloses a kind of multifunctional tour guide explanation The machine is composed of a transmitter carried by the tour guide and a receiver carried by the tourists. The voice of the tour guide is converted into an audio signal by the microphone and transmitted in the form of frequency modulation. When receiving the signal from the transmitter, the radio frequency modulation is cleverly used The circuit can organically combine the functions of radio and intercom, which is convenient and practical, and the circuit is reasonable and compact, and i...

Problems solved by technology

However, the biggest defect of this type of tour guide machine is that it is susceptible to external interference, especially if there are multiple tour groups in the same scenic spot, it is very easy to generate mutual signal interference on the same channel

On May 10, 2000, the No. 99223093.4 Chinese Utility Model Patent, which was authorized by the announcement on May 10, 2000, discloses a digital recording infrared transmission tour guide, which uses infrared rays for transmission, which can overcome the mutual interference between various signals, but the disadvantage is that infrared rays are easy to Obstructed by obstacles such as human bodies, the receiver cannot receive infrared signals, so it is impossible to communicate when tourists leave a certain distance and have certain obstacles
