Description
本新型係一種導盲系統，特別是一種結合可探測距離的導盲杖及通訊裝置的智慧導盲系統。 This new device is a blind guide system, in particular, an intelligent blind guide system that combines a distance-detectable blind guide stick and a communication device.
盲人在移動時是非常不方便的。由於眼睛無法探查外部光影的變化，盲人很容易受到路面障礙物而跌倒。因此，市面上有許多輔助盲人行動的輔助工具，導盲拐杖是其中一種。導盲拐杖由一根長度適中的手柄和底部的支撐組成。導盲拐杖的主要功能是幫助視力受損者在行動中感知和避開障礙物，提高他們的安全性和獨立性。使用導盲拐杖時，視力受損者會輕輕地將拐杖搖動於身體前方，感受地面的反饋。當拐杖觸及地面上的障礙物時，它會產生振動或發出聲音，提醒使用者需要注意。 It is very inconvenient for blind people to move. Since the eyes cannot detect the changes in external light and shadow, blind people are easily affected by obstacles on the road and fall. Therefore, there are many assistive tools on the market to assist blind people in their movements, and the guide cane is one of them. The guide cane consists of a handle of moderate length and a support at the bottom. The main function of the guide cane is to help the visually impaired perceive and avoid obstacles during movement, thereby improving their safety and independence. When using a guide cane, the visually impaired person will gently shake the cane in front of the body to feel the feedback from the ground. When the cane touches an obstacle on the ground, it will vibrate or make a sound to remind the user that he needs to pay attention.
某些導盲拐杖還有測距的功能，讓使用者可以提前知道面前有障礙物，典型的案例為中華民國發明專利第I786919號。該專利揭露一種智慧型盲人拐杖，其具有一把手及一桿體。該桿體設有一水平測距裝置及一垂直測距裝置，且該把手或該桿體內設有一控制單元及一警示裝置，俾以在一盲人依該拐杖探路之過程中，若該桿體位於一坑洞上方或該桿體與前方一障礙物之距離小於一閾值時，使該警示裝置發出警示信號以提醒該盲人。這種導盲拐杖雖然可以提醒盲人，但使用上並不方便。一來盲人可能會誤解警示裝置發出的警訊，二來如果該警訊太明顯，容易影響週遭的其他人。 Some guide canes also have a distance measuring function, allowing users to know in advance that there are obstacles in front of them. A typical case is the Republic of China invention patent No. I786919. The patent discloses a smart cane for the blind, which has a handle and a rod. The rod is provided with a horizontal distance measuring device and a vertical distance measuring device, and a control unit and a warning device are provided in the handle or the rod, so that when a blind person uses the cane to explore the road, if the rod is located above a pit or the distance between the rod and an obstacle in front is less than a threshold, the warning device will send a warning signal to remind the blind person. Although this guide cane can remind the blind, it is not convenient to use. First, the blind may misunderstand the warning signal issued by the warning device, and second, if the warning signal is too obvious, it is easy to affect other people around.
為了解決上述問題，從而有本新型之濫觴。 In order to solve the above problems, this new type of device is proposed.

本新型改進現有導盲拐杖在本體產生震動以提醒盲人的設計，將震動的產生改由放置在身上的通訊裝置來執行。如此一來，盲人可更有效察覺震動，藉由漸進式的震動區別障礙物的距離，不會誤解通訊裝置發出的警訊。其次，通訊裝置的震動只有盲人自己能感受，不會影響週遭的其他人。 This new design improves the existing design of the guide cane that generates vibrations to alert the blind, and the vibrations are generated by the communication device placed on the body.

本新型將藉由參照下列的諸實施例而更具體地描述。 The present invention will be described in more detail with reference to the following embodiments.
請見圖1，該圖為本新型實施例的一種智慧導盲系統1的外觀示意圖。本新型的智慧導盲系統1包含了一通訊裝置10與一智能導盲杖20。以下分別說明 這些技術元件的型態、結構，以及智慧導盲系統1的運作方式。 Please see Figure 1, which is a schematic diagram of the appearance of a smart blind guide system 1 of the present new embodiment. The present new smart blind guide system 1 includes a communication device 10 and a smart blind guide stick 20. The following describes the type and structure of these technical components, as well as the operation of the smart blind guide system 1.
通訊裝置10可通過無線通訊方式接收一警示訊號，依照該警示訊號產生對應的震動型態。警示訊號的內含將於下方詳述。關於通訊裝置10內的具體電路架構，請見圖2，該圖為通訊裝置10的電路方框圖。通訊裝置10包含了一電力單元11、一第一藍芽通訊單元12、一振動器13與一處理單元14。電力單元11提供與之電連接元件運作時所需的電力。在本說明書的圖式中，所有元件間的電連接以粗實線繪示，以區別於訊號連接的細虛線。電力單元11可以是個二次電池，藉由反覆的充電以提供其消耗於第一藍芽通訊單元12、振動器13與處理單元14上的電力。電力單元11也可以是個一次電池，電力用完即更換。第一藍芽通訊單元12與電力單元11電連接，用以接收該警示訊號。意即本新型的無線通訊方式是藍芽通訊，可實現端到端的通訊而無須經過第三方。振動器13與電力單元11電連接，受處理單元14控制以產生不同頻率的震動。通訊裝置10安裝於盲人身上，比如腰間，這個震動便可用來提醒盲人前方障礙物分布的情況。實作上，振動器13可以是個微型馬達。處理單元14與電力單元11電連接，並與第一藍芽通訊單元12及振動器13訊號連接。處理單元14的功能為依照警示訊號的指示控制振動器13的震動。 The communication device 10 can receive an alarm signal through wireless communication and generate a corresponding vibration pattern according to the alarm signal. The content of the alarm signal will be described in detail below. Regarding the specific circuit architecture in the communication device 10, please see Figure 2, which is a circuit block diagram of the communication device 10. The communication device 10 includes a power unit 11, a first Bluetooth communication unit 12, a vibrator 13 and a processing unit 14. The power unit 11 provides the power required for the operation of the components electrically connected to it. In the figures of this specification, the electrical connections between all components are drawn with thick solid lines to distinguish them from the thin dashed lines of the signal connections. The power unit 11 can be a secondary battery, which is repeatedly charged to provide the power consumed by the first Bluetooth communication unit 12, the vibrator 13 and the processing unit 14. The power unit 11 can also be a primary battery, which is replaced when the power is exhausted. The first Bluetooth communication unit 12 is electrically connected to the power unit 11 to receive the warning signal. This means that the wireless communication method of the present invention is Bluetooth communication, which can achieve end-to-end communication without going through a third party. The vibrator 13 is electrically connected to the power unit 11 and is controlled by the processing unit 14 to generate vibrations of different frequencies. The communication device 10 is installed on the blind person, such as the waist, and this vibration can be used to remind the blind person of the distribution of obstacles in front. In practice, the vibrator 13 can be a micro motor. The processing unit 14 is electrically connected to the power unit 11, and is signal-connected to the first Bluetooth communication unit 12 and the vibrator 13. The function of the processing unit 14 is to control the vibration of the vibrator 13 according to the instructions of the warning signal.
實作上，通訊裝置10為智慧型手機，安裝一行動應用程式以驅動處理單元。也就是安裝了行動應用程式的智慧型手機便可在不需要人為控制的情況下，控制振動器13的震動。 In practice, the communication device 10 is a smart phone, which is installed with a mobile application to drive the processing unit. That is, the smart phone with the mobile application installed can control the vibration of the vibrator 13 without manual control.
如圖1所示，智能導盲杖20包含了一杖體21、一手把22及一距離偵測模組23。杖體21用來輔助支撐盲人，在觸及地面的同時也可讓盲人知道路面的地形變化。手把22裝設於杖體21上方，用以讓盲人手持。距離偵測模組23可持續發射測距超聲波並接收回傳超聲波，以確認智能導盲杖20前方一特定距離內有無阻礙物。當出現阻礙物時，智能導盲杖20可以無線通訊方式發出前述的警示 訊號給通訊裝置10，讓振動器13產生對應的震動。關於距離偵測模組23的具體架構，請見圖3，該圖為距離偵測模組23的電路方框圖。 As shown in FIG1 , the smart cane 20 for the blind includes a cane body 21, a handle 22, and a distance detection module 23. The cane body 21 is used to assist and support the blind person, and can also let the blind person know the terrain changes of the road surface while touching the ground. The handle 22 is installed above the cane body 21 for the blind person to hold. The distance detection module 23 can continuously emit ranging ultrasonic waves and receive returned ultrasonic waves to confirm whether there are obstacles within a specific distance in front of the smart cane 20 for the blind. When an obstacle appears, the smart cane 20 can send the aforementioned warning signal to the communication device 10 in a wireless communication mode, so that the vibrator 13 generates corresponding vibrations. For the specific structure of the distance detection module 23, please see Figure 3, which is a circuit block diagram of the distance detection module 23.
距離偵測模組23包含了一電池單元231、一超音波測距單元232、一第二藍芽通訊單元233及一控制板234。電池單元231可提供與之電連接元件運作時所需的電力，即對控制板234提供電力。在本實施例中，電池單元231包含了一電力轉換器2311、一二次電池芯2312與一開關2313。電力轉換器2311用來將一外部交流電源(未繪示)提供的交流電力轉換為直流電力。實作上，電力轉換器2311可以是個變壓器。二次電池芯2312與電力轉換器2311電連接，可儲存該直流電力並可提供電力管理器2311電力。開關2313開啟或關閉二次電池芯2312與控制板234間的電連接。 The distance detection module 23 includes a battery unit 231, an ultrasonic distance measurement unit 232, a second Bluetooth communication unit 233 and a control board 234. The battery unit 231 can provide the power required for the operation of the components electrically connected thereto, that is, provide power to the control board 234. In the present embodiment, the battery unit 231 includes a power converter 2311, a secondary battery core 2312 and a switch 2313. The power converter 2311 is used to convert the AC power provided by an external AC power source (not shown) into DC power. In practice, the power converter 2311 can be a transformer. The secondary battery core 2312 is electrically connected to the power converter 2311, can store the DC power and provide power to the power manager 2311. The switch 2313 opens or closes the electrical connection between the secondary battery cell 2312 and the control board 234.
超音波測距單元232是用來偵測智能導盲杖20與障礙物間距離的元件，包含了一發射器2321與一接收器2322。發射器2321向手把22的一前進方向續發射該測距超聲波。前進方向是個指示方向，當盲人在手持智能導盲杖20前行時，手把22前進方向應平行於他的移動方向，從而能確認前方是否有障礙物。如果將前進方向變了角度，那偵測到的障礙物不會影響該盲人的行進，反倒是真實行進方向上的障礙物會偵測不到。在本實施例中，為了讓盲人能掌握手把22的前進方向，手把22上有至少一指向突起物221(本實施例中有2個)。指向突起物221突出形成於手把22上，可讓使用者於握持手把22時，藉由觸及該至少一指向突起物221而知道該前進方向。實際上，如圖3所示，測距超聲波(以較大空心箭號表示)由於發射時的物理特性，其行進方向與前進方向(以點虛線表示)間會有一個夾角α，測距超聲波在夾角α所包的範圍內向外傳播。在本實施例中，夾角α小於15度。接收器2322可接收該測距超聲波因觸及阻礙物而反射的該回傳超聲波(以較小空心箭號表示)。由於超音波測距單元232能有效且準確測定的距離有限，比如5公尺，前述的特定距離即是在有效測定距離內的距離， 比如4公尺以內，讓盲人能大概知道前方較近障礙物的距離。第二藍芽通訊單元233是智能導盲杖20端的通訊元件，可向第一藍芽通訊單元12傳輸該警示訊號。 The ultrasonic ranging unit 232 is a component used to detect the distance between the smart guide stick 20 and obstacles, and includes a transmitter 2321 and a receiver 2322. The transmitter 2321 continues to emit the ranging ultrasonic wave in a forward direction of the handle 22. The forward direction is an indication direction. When a blind person walks forward while holding the smart guide stick 20, the forward direction of the handle 22 should be parallel to his moving direction, so that he can confirm whether there are obstacles in front. If the forward direction is changed at an angle, the detected obstacle will not affect the blind person's progress, but the obstacle in the real direction of travel will not be detected. In this embodiment, in order to allow the blind person to grasp the forward direction of the handle 22, there is at least one directional protrusion 221 on the handle 22 (there are 2 in this embodiment). The directional protrusion 221 is formed on the handle 22, so that the user can know the forward direction by touching the at least one directional protrusion 221 when holding the handle 22. In fact, as shown in FIG3, due to the physical characteristics of the ranging ultrasonic wave (indicated by a larger hollow arrow) during emission, there is an angle α between its traveling direction and the forward direction (indicated by a dotted line), and the ranging ultrasonic wave propagates outward within the range of the angle α. In this embodiment, the angle α is less than 15 degrees. The receiver 2322 can receive the return ultrasonic wave (indicated by a smaller hollow arrow) reflected by the ranging ultrasonic wave touching an obstacle. Since the ultrasonic ranging unit 232 can effectively and accurately measure a limited distance, such as 5 meters, the aforementioned specific distance is within the effective measurement distance, such as within 4 meters, so that the blind can roughly know the distance of the nearest obstacle in front. The second Bluetooth communication unit 233 is a communication element at the end of the smart guide stick 20, which can transmit the warning signal to the first Bluetooth communication unit 12.
控制板234與電池單元231電連接，並與超音波測距單元232及第二藍芽通訊單元233電連接及訊號連接。控制板234包含了一電力管理器2341與一微控制器2342。電力管理器2341提供超音波測距單元232及第二藍芽通訊單元233運作時所需的電力。實作上，電力管理器2341是個電力控制晶片。微控制器2342可執行以下作業。第一、依照該回傳超聲波測算超音波測距單元232與阻礙物間的一間隔距離。第二、將該間隔距離對應的一震動頻率加入該警示訊號中，讓通訊裝置10依照該震動頻率產生對應的震動型態。比如間隔距離在3-4公尺內，震動頻率為每隔一秒震動一次，每次震動持續0.5秒；間隔距離在2-3公尺內，震動頻率為每隔0.5秒震動一次，每次震動持續0.5秒；間隔距離在1-2公尺內，震動頻率為每隔0.25秒震動一次，每次震動持續0.5秒；間隔距離在3-4公尺內，震動頻率為每隔一秒震動一次，每次震動持續0.5秒；間隔距離在1公尺內，震動頻率持續震動。通訊裝置10的震動猶如倒車警訊，由較遠時的「嘟、停、嘟、停、嘟...」，到車子快碰到障礙物時的「嘟嘟嘟嘟嘟...」響聲，只不過改為震動，只有盲人自己感受到，不會影響周圍人。 The control board 234 is electrically connected to the battery unit 231, and is electrically and signally connected to the ultrasonic ranging unit 232 and the second Bluetooth communication unit 233. The control board 234 includes a power manager 2341 and a microcontroller 2342. The power manager 2341 provides the power required for the ultrasonic ranging unit 232 and the second Bluetooth communication unit 233 to operate. In practice, the power manager 2341 is a power control chip. The microcontroller 2342 can perform the following operations. First, calculate the interval distance between the ultrasonic ranging unit 232 and the obstacle according to the returned ultrasonic wave. Second, add a vibration frequency corresponding to the interval distance to the warning signal, so that the communication device 10 generates a corresponding vibration pattern according to the vibration frequency. For example, if the distance is within 3-4 meters, the vibration frequency is once every second, and each vibration lasts for 0.5 seconds; if the distance is within 2-3 meters, the vibration frequency is once every 0.5 seconds, and each vibration lasts for 0.5 seconds; if the distance is within 1-2 meters, the vibration frequency is once every 0.25 seconds, and each vibration lasts for 0.5 seconds; if the distance is within 3-4 meters, the vibration frequency is once every second, and each vibration lasts for 0.5 seconds; if the distance is within 1 meter, the vibration frequency is continuous. The vibration of the communication device 10 is like a reversing warning, from "beep, stop, beep, stop, beep..." when the car is far away to "beep beep beep beep..." when the car is about to hit an obstacle, but it is changed to vibration, which can only be felt by the blind person and will not affect people around him.
請見圖4，該圖繪示智慧導盲系統1的使用方式。在圖4中，一位盲人手持智能導盲杖20，將通訊裝置10細於腰間。智能導盲杖20的超音波測距單元232向前進方向發出測距超聲波(以實線箭號表示)。測距超聲波遇到前方一台機車2後反射，反射的回傳超聲波(以點線箭號表示)再為超音波測距單元232接收。微控制器2342計算出了間隔距離，將該間隔距離對應的震動頻率加入警示訊號中，並將該警示訊號傳輸給通訊裝置10(以虛線箭號表示)，驅動振動器13依照該震動頻率震動。盲人藉由震動，可以轉向以避開機車2。 Please see Figure 4, which shows how to use the smart blind guide system 1. In Figure 4, a blind person holds a smart blind guide stick 20 and holds the communication device 10 at his waist. The ultrasonic ranging unit 232 of the smart blind guide stick 20 emits a ranging ultrasonic wave in the forward direction (indicated by a solid arrow). The ranging ultrasonic wave is reflected after encountering a motorcycle 2 in front, and the reflected return ultrasonic wave (indicated by a dotted arrow) is then received by the ultrasonic ranging unit 232. The microcontroller 2342 calculates the interval distance, adds the vibration frequency corresponding to the interval distance to the warning signal, and transmits the warning signal to the communication device 10 (indicated by a dotted arrow), driving the vibrator 13 to vibrate according to the vibration frequency. The blind person can turn to avoid the motorcycle 2 by vibration.
