Abstract

The invention relates to the technical field of special devices in a court, in particular to a court projection demonstration device. The demonstration device comprises three display terminals, a master controller, three projectors corresponding to the display terminals, a wireless transceiver, a master LED lamp group, a microphone and a loudspeaker, wherein the wireless transceiver, the master LED lamp group, the microphone and the loudspeaker are connected with the master controller. The first display terminal is a master display terminal. The second display terminal and the third display terminal are slave display terminals. The demonstration device also comprises a first slave LED lamp group connected with the second display terminal and a second slave LED lamp group connected with the third display terminal. The master controller is connected with a first slave controller and a second slave controller. The projectors are connected with the master controller. The display terminals are arranged on push-and-pull tracks. The first display terminal is connected with an encoder. In this way, trial efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of court special equipment, in particular to a court projection demonstration device. Background technique [0002] Now most of the courts use paper to exchange statements, and view evidence through dictation or circulation, which reduces the efficiency of court presentations. Contents of the invention [0003] The embodiment of the present invention solves the technical problem in the prior art that the efficiency of transferring evidence is relatively low and affects the trial efficiency by providing a court projection demonstration device. [0004] In order to solve the above technical problems, the technical solutions of the embodiments of the present invention are as follows: [0005] A court projection demonstration device, including three display terminals, a main controller, three projectors corresponding to the three display terminals, a wireless transceiver connected to the main controller, a ma...
