Background technique

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 not take into account the visually impaired, such as the elderly, the partially sighted and the blind. Visually impaired people cannot use general air conditioner remote controls and panels, and need to use a system that can control the air conditioner through voice prompts without looking at the buttons.

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, the main chip of the air conditioner, a voice drive module and a speaker. The voice drive module is electrically connected to the main chip of the air conditioner 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 and adjust the air conditioner. The air conditioning system for the blind and the remote control for the blind require the user to purchase a special air conditioner and remote control, and the price of this special air conditioning system and remote control is extremely expensive due to the small demand, and few manufacturers are willing to invest in production. Therefore, cannot be generalized in real-world applications.

A Chinese patent application (Application No.: 201120119445.3) discloses a decoding-type air conditioner voice announcer, which includes an air conditioner remote control receiving device, a decoding controller, a voice chip and a speaker that are electrically connected in sequence. The remote control, the decoding type air conditioner voice announcer is a separate device, the air conditioner remote control sends commands to the voice announcer and the air conditioner at the same time to realize voice broadcast and control the air conditioner, the user only needs to place it at a suitable position next to the air conditioner The decoding type air conditioner voice announcer can be used. 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 command, 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 it, resulting in a false report. 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.

Beneficial technical effect of the present invention:

Different from the prior art, the present invention does not make the voice announcer on the electric appliance and the electric appliance controls the voice broadcast, nor does it use a separate device to receive the infrared remote control signal sent by the remote controller to the electric appliance to realize the voice broadcast, but sets up a The voice broadcaster of the bridging device between the remote control and the electrical appliance realizes the RF infrared forwarding through the RF receiving module and the infrared transmitting module, and simultaneously performs voice broadcasting, which brings the following significant advantages:

Because there is no need for electrical appliance manufacturers to modify the electrical appliance itself on a large scale (such as adding a voice driver module) in order to realize voice broadcasting, and because the remote control signal is finally converted into an infrared signal, the electrical appliance can still use the traditional infrared remote control, so the cost can be maintained , to ensure the product's generalizability. Since the radio frequency remote control signal of the remote controller is bridged by the voice broadcaster to realize infrared forwarding, it is ensured that the electrical appliance is remotely controlled and at the same time it is basically necessary to perform accurate voice broadcasting. The problems caused fundamentally eliminate the occurrence of missed reports of the voice announcer, and as long as the infrared transmitter module of the voice announcer is adjusted to align with the electrical appliances without hindrance, the occurrence of false reports can also be effectively avoided. Since the remote control and the voice announcer communicate in a radio frequency wireless manner, it can overcome the shortcomings of the traditional infrared remote control, including the need for the remote control to be directed at the electrical appliances within the visible range, and only the infrared emission module of the voice announcer Aiming at electrical appliances greatly increases the controllable distance between the remote control and electrical appliances, for example, the remote control can not be implemented in the same room. Based on the physical characteristics of radio frequency, the remote control signal can penetrate objects such as walls that block the line of sight. The remote control distance of radio frequency is also farther than the general infrared remote control distance (1 to 5 meters). Under the same control conditions, it can easily reach 20 to 50 meters. According to different applications, the remote control distance can be further extended by slightly increasing the power. Compared with the higher power consumption of infrared remote control, the power consumption of radio frequency remote control is lower, which is conducive to prolonging the working time of remote control. Since small batteries can be used, it is also conducive to the miniaturization of remote control products.

In a preferred embodiment, the voice announcer adopts a box structure, and the box body is provided with a power plug, so that the power plug can be directly inserted into the power socket, and the voice announcer is powered by the internal power supply circuit of the box body. There is an infrared hole, and the infrared head is exposed outside the box through the infrared hole. As long as the direction is adjusted once, the infrared head is aligned with the electrical appliance to be controlled, and there is no need to change it. It completely prevents missed and false reports, and is simple and convenient to use. Moreover, the box body with the power plug serves the purpose of fixing the voice announcer and supplying power to it at the same time, killing two birds with one stone. Further, the part where the infrared head is installed in the box is movably connected to the part where the power plug is installed. This structure makes the direction of the infrared head adjustable, such as moving up and down, left and right, or tilting, which can easily adjust the direction of the infrared head. , so that the voice announcer can be aligned with the electrical appliances when plugged into sockets in different positions, so that it has strong flexibility and adaptability in use.

In a preferred embodiment, the voice announcer is equipped with a memory, more preferably an external interface module, the memory can store a variety of different remote control coding libraries, and these remote control coding libraries can be used with different types of electrical appliances and different types of electrical appliances Corresponding to the matching, the control unit can choose to read one of the remote control code libraries into the ROM according to the instructions input by the user through the remote control. If the ROM has been read, the original remote control code library will be updated, so that it can On the premise of replacing the voice announcer, a set of remote control and voice broadcast system is suitable for various electrical appliances, so it has extremely wide applicability and flexibility, and at the same time greatly saves the cost of replacing the remote control system for different electrical appliances. In addition, through the external interface module, the new remote control coding library can be written into the memory from the outside, which is more convenient and further improves the flexibility. Since the voice announcer is separated from the remote controller and does not require user operation at ordinary times, even if the voice announcer is equipped with a memory or relatively increased in size, it will not affect the convenience for users to use the system.

The present invention is not only applicable to air conditioners, but also to other electric appliances controlled by remote control, such as set-top boxes and the like. Moreover, the present invention can not only provide great help for the visually impaired, but also provide great convenience and good experience for users with healthy eyesight.
