Description

technical field [0001] The invention relates to electrical equipment, in particular to a remote control and voice broadcast system, a voice broadcaster and a voice broadcast box. Background technique [0002] According to statistics, about 200 million people around the world suffer from visual disabilities, and about 50 million of them are blind. Nine out of every 10 blind people in the world live in developing countries. There are currently about 5 million blind people in China, and about 20 million people with visual disabilities, ranking first in the world. In addition, with the rapid development of China's economy, the penetration rate of air conditioners in my country has reached a relatively high level. The ownership rate of air conditioners in households in first-tier cities has reached 64.8%, while that in second- and third-tier cities has reached 50.3%, 39.6%. However, the vast majority of air conditioners currently on sale are only aimed at normal people, and do ...

Problems solved by technology

[0003] A Chinese patent application (Application No.: 200920178968.8) discloses an air conditioner system for the blind and a remote control for the blind, including buttons, an air conditioner main chip, a voice drive module and a speaker. The voice drive module is electrically connected to the air conditioner main chip and the speaker respectively. The control signal is sent through the buttons of the remote control. After receiving the control signal, the main chip of the air conditioner will broadcast the corresponding function of the button through the voice driver module and the speaker, so that when operating the remote control, there is no need to look at the mark on the button, which overcomes the existing problems. The remote control and panel of the air conditioner in the technology can be used by normal people, but the visually impaired cannot operate the air conditioner to adjust the problem

However, when the decoding-type air conditioner voice announcer is in use, since the wireless transmission is through infrared light wave signals, a problem will occur, that is, when the air conditioner receives the remote control instruction, the voice announcer does not receive it and the situation of missing reports occurs. , or the air conditioner did not receive the command from the remote control when the voice announcer received the command, and a false report occurred

There is another problem, that is, because the effective control distance of the infrared light wave signal is 10 meters, and the remote control needs to be pointed at the air conditioner for effective control, this is obviously unrealistic for the visually impaired. Therefore, when using the decoding type air conditioner When using the voice announcer, the visually impaired person may press the button several times without any response
