Anti-interference wireless talkback system and installation method

Abstract

The invention discloses an anti-interference wireless intercom system and an installation method. The system comprises a master controller and a plurality of communication terminals connected with themaster controller through short wave communication. The plurality of signal terminals are uniformly distributed in the shopping mall; the communication terminal comprises a positioning frame, a movable frame, a protection box, a processor, a short wave antenna, a signal converter and a talkback device. A movable frame is installed on the positioning frame, the protection box is installed on the movable frame, the processor is arranged in the protection box, the supporting plate is arranged at the top of the protection box, the short-wave antenna connected with the processor is installed on the supporting plate, and the talkback device connected with the processor is installed on the movable frame on the lower portion of the protection box. By arranging the liftable movable frame, the short-wave antenna installed above the protection box can be rapidly lifted, so that a bottom-layer building in a shopping mall is prevented from blocking transmission of short-wave signals, the stabilityof the short-wave antenna is improved, and meanwhile, the anti-interference performance of the wireless intercom system is improved.

Description

technical field [0001] The invention relates to the field of short-wave communication, in particular to an anti-jamming wireless intercom system and an installation method. Background technique [0002] With the development of the economy, the current shopping malls are getting bigger and bigger, the structure is getting more and more novel, and the flow of people in the shopping malls is gradually increasing.
