Accompanying drawing explanation
Fig. 1 is that a kind of blind person of the utility model takes action structured flowchart that is auxiliary and long distance control system.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.
The utility model uses ranging technology, wireless communication technology and software engineering, ultrasonic technology, infrared technique and gyroscope technology is combined, and utilizes software to control multiple sensors work by processor, realizes obstacle distance and measures; Utilize voice technology and vibrations technology, realize keeping away barrier induction prompting.
With reference to figure 1, the utility model system comprises portable unit and the ZigBee networking module that is connected with portable unit and intelligent and portable terminal.
Portable unit comprises processor, range finder module, temperature measurement module, gyro module, reminding module and communication module.
Range finder module comprises ultrasonic wave module and infrared module.
Ultrasonic wave module comprises at least one ultrasound wave transmitter module and a ultrasound wave receiver module.Processor controls ultrasound wave transmitter module and launches ultrasonic signal, and ultrasonic signal runs into barrier reflection, and ultrasound wave receiver module receives reflected signal, and processor can dyscalculia thing distance by transmitting and receiving signal time difference.Select dissimilar and unequal number amount ultrasonic wave module to carry out range observation, barrier shape recognition rate can be improved, increase barrier measurement range.
Infrared module comprises at least one infrared transmission module and an infrared receiving module.Because ultrasound wave has blind area when closely finding range, thus use infrared module measure closely barrier, its range measurement principle and ultrasound wave similar.
Because ultrasonic signal propagation speed is relevant with temperature, the real-time detected temperatures value of temperature measurement module need be used and upgrade result of calculation, to improve distance accuracy when therefore calculating.
