Abstract
The utility model discloses a wireless article-searching system for blindmen, which comprises an emitter and is characterized by also comprising a plurality of independent receivers attached to target objects. Each independent receiver comprises a sound alarm unit. The emitter and the receivers are communicated with each other in the wireless communication mode. According to the technical scheme of the utility model, the receivers of the wireless article-searching system for blindmen can be fixedly attached to each of the target objects respectively for a long time. When one of the target objects makes a sound, the position of the corresponding target object can be found out through identifying a braille switch on the emitter. The braille switch corresponds to eight receivers in the software code matching mode and each button is provided with a unique identification code. Therefore,the repetition rate is 1 of 650000. The entire wireless article-searching system adopts low-power transmitting and receiving modules and the low-power mode of the system is switched on in the software control mode, wherein a 300 mAh lithium battery capable of running continuously for 25 days is adopted. Meanwhile, the wireless article-searching system for blindmen is simple to operate and convenient and easy to use.

Technical field
The utility model relates to a kind of disabled person's equipment, is specifically related to the wireless system that looks for something of a kind of blind person.
Background technology
The blind person is employed various article in live and work, must leave the fixed position in, are moved such as article, and the blind person seeks article and gets up very difficult.How solving the problem in these blind person's daily lifes, make things convenient for their daily life, is present problem demanding prompt solution.
Summary of the invention
In order to overcome this problem, the utility model provides a kind of simple, convenient easy-to-use blind person the wireless system that looks for something.
The technical solution of the utility model is the wireless system that looks for something of a kind of blind person, it comprises transmitter, it is characterized in that: it comprises that also several are attached to the independent receiver on the object, described independent receiver comprises the audible alarm unit, the mode communication by wireless telecommunications between described transmitter and the independent receiver.
Preferably, described transmitter and independent receiver include radio communication unit, software to code system, single-chip microcomputer and power module.
Preferably, described transmitter also comprises one to one button of a plurality of and described independent receiver.The output terminal of button is connected on the key control circuit of single-chip microcomputer.As, 8 buttons can have 8 button control pins, by software code system are encoded, and the signal behind the coding is received the modulated terminal of transmitter module by the output terminal of single-chip microcomputer, carries out wireless transmission by radio communication unit.The radio communication unit of receiver is decoded through single-chip microcomputer after receiving the transmitter codes signal, confirms unanimously with the address code of the machine, and the output high level triggers sound generating circuit and sends the sound.Transmitter and receiver adopt software that the code form is identified by software to code system, carry out corresponding one by one with receiver the button on the transmitter respectively.
Preferably, described button is braille keys, and namely numbered braille is established on the surface of button.
Preferably, described button is the sounding button.Be provided with phonation unit on the transmitter, it is to send " ticking " one that each button is pressed.
Preferably, described independent receiver also comprises a bandage, and described bandage can connect into by VELCRO or snap-fastener the annular of sealing.
Preferably, be provided with on the described independent receiver for the adhesive sticker that described independent receiver is sticked on the object.In addition, can also adopt modes commonly used such as " cover are hung, and folder is held, and takes, and button glues, and inhales ", so that described independent receiver is attached on the object.
The receiver of the wireless system that looks for something of a kind of blind person of the present utility model can be for a long time attached solid on each object, and by the braille switch on the identification transmitter, object sends the sound, can find corresponding article position.To 8 receivers of code form responding, each button has unique identification code by software, and repetition rate can reach 1,/65 ten thousand.The transmitting and receiving module of whole machine using low power consumption all adopts the software control mode to enter low-power consumption mode, adopts the lithium battery of 300mAh, and stream time is 25 days.The utlity model has the simple, convenient advantage such as easy-to-use.

Embodiment
The below is described in further detail embodiment of the present utility model.
As shown in Figure 1, the wireless system of looking for something of a kind of blind person of the present utility model comprises transmitter 10, and it also comprises 8 independent receivers 14 that are attached on the object 12.Comprise on the transmitter 10 8 with independent receiver button 16 one to one.Button 16 can be designed to braille keys and sounding button as required, and namely numbered braille is established on the surface of button.Independent receiver 14 can adopt modes commonly used such as " cover are hung, and folder is held, and takes, and button sticking, is inhaled ", so that independent receiver 14 is attached on the object 12.What show among Fig. 1 is to tie up example on vacuum flask by a bandage 18.Clip, adhesive sticker, rope sling, hook etc. can be so that independent receiver 14 can be attached to the effect that device on the object 12 can substitute bandage 18.
As shown in Figures 2 and 3, transmitter 10 and independent receiver 14 include radio communication unit, software to code system, single-chip microcomputer and power module, and wherein power module is lithium battery.Independent receiver comprises the audible alarm unit, the mode communication by wireless telecommunications between transmitter and the independent receiver.The output terminal of button is connected on the key control circuit of single-chip microcomputer.8 buttons can have 8 button control pins, by software code system are encoded, and the signal behind the coding is received the modulated terminal of transmitter module by the output terminal of single-chip microcomputer, carries out wireless transmission by radio communication unit.The radio communication unit of receiver is decoded through single-chip microcomputer after receiving the transmitter codes signal, confirms unanimously with the address code of the machine, and the output high level triggers sound generating circuit and sends the sound.Transmitter and receiver adopt software that the code form is identified by software to code system, carry out corresponding one by one with receiver the button on the transmitter respectively.
Above embodiment only is the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
