Description

手機測距裝置 Mobile phone distance measuring device

本發明係一種手機測距裝置,尤指一種透過發光元件所投射之光線照射出反射光點,即可快速量測其距離者。 The invention relates to a mobile phone distance measuring device, in particular to a person who can directly measure the distance by irradiating a reflected light spot through the light projected by the light emitting element.

按,距離係基本且重要的參數,其係為求兩點間之長度,量測距離之裝置及方法所在多有,習見之距離量測如直接距離測量法,其係透過尺具(如:捲尺、皮尺)直接量測兩點之距離,惟尺具所能及之距離受限,且常因尺具因未完全拉伸,或因待測物之形狀及大小而造成其量測誤差,再者,其對於使用者需自行量測其身高時,需將該尺具平貼於樑柱等與地面完全垂直之標的物,再自行標定其身高於該尺具之位置,藉以得知該使用者自身之高度,然而,其過程相當耗時,且無法即時找尋至與地面完全垂直之標的物予以量測,自行標定其身高於該尺具之位置亦需其他工具輔助標定,否則容易產生誤差,因此,利用直接距離測量需齊備之用具數量過多、無法即時自行量測身高及容易產生誤差等缺失,且往往需他人輔助配合,方能準確量測該使用者之身高。 According to the distance, the basic and important parameters are the length between the two points. There are many devices and methods for measuring the distance. The distance measurement is like the direct distance measurement method, which is transmitted through the ruler (eg: Tape measure and tape measure directly measure the distance between two points, but the distance between the ruler and the ruler is limited, and the measurement error is often caused by the ruler being incompletely stretched or due to the shape and size of the object to be tested. Moreover, when the user needs to measure the height of the user himself, the ruler should be flatly attached to the object perpendicular to the ground such as the beam and the column, and then the body is calibrated to be higher than the position of the ruler, thereby knowing the The user's own height, however, the process is quite time consuming, and it is impossible to find the object that is completely perpendicular to the ground in real time. It is easy to produce other tools to calibrate the position of the body above the ruler. The error, therefore, the use of direct distance measurement requires a large number of tools, can not automatically measure the height and easy to produce errors, and often need to assist others to accurately measure the height of the user.

續之,習知另提供一種利用電磁波或超音波之量測裝置及其方法者,如中華民國專利第I253500號「一種攜帶式超音波 身高量測裝置」,其主要係藉由一顯示單元打開翻轉與量測單元呈垂直;並令使用者貼牆站立使其身體背部與牆壁成平行之形態,再藉由第一底蓋緊貼於牆面,而量測單元則與牆壁成垂直角度並置於該使用者頭頂處,並透過超音波接收器收受發射器發送一超音波,經地面反彈並由超音波接收器收受該反射後之超音波,藉其時間差以推算使用者之身高值;其於實施身高量測之操作時,令被量測者將其背部靠著牆壁站立,並使其身體背部與牆壁成平行之形態,再由操作者將本發明之一種攜帶式超音波身高量測裝置置放於被量測者之頭頂,而量測單元與牆壁成垂直角度握持不放,此時本發明之攜帶式超音波身高量測裝置固定不動,接著令被量測者離開後,操作者以食指按下啟動鍵之開關鍵,聽到揚聲器發出「嗶」聲後即表示量測完成,操作者即可從液晶螢幕看出所量測之身高數值,此操作方式需要兩人(即操作者與被量測者)方能完成,且量測單元與牆壁必須成垂直角度,其實際操作不易,且於欲量測水平距離時,該第一底蓋亦無標的物藉以定位,故亦無法精確量測與待測物間之水平距離,其適用性顯然不足,此外,其需使用者另行攜帶,而無法與日常生活用品結合,將增加使用者攜帶之困擾。 In addition, the conventional method provides a measuring device using electromagnetic waves or ultrasonic waves and a method thereof, such as the Republic of China Patent No. I253500 "a portable ultrasonic wave. The height measuring device is mainly perpendicular to the measuring unit by opening and flipping a display unit; and the user is placed on the wall so that the back of the body is parallel to the wall, and then the first bottom cover is closely attached. On the wall surface, the measuring unit is perpendicular to the wall and placed at the top of the user's head, and receives an ultrasonic wave through the ultrasonic receiver receiving the transmitter, rebounds through the ground and receives the reflection by the ultrasonic receiver. Ultrasonic wave, by which the time difference is used to estimate the height value of the user; when performing the height measurement operation, the measured person stands his back against the wall and makes his body back parallel to the wall, and then The portable ultrasonic measuring device of the present invention is placed on the top of the head of the measured person, and the measuring unit is held at a vertical angle to the wall. At this time, the portable ultrasonic height of the present invention is high. The measuring device is fixed, and then the operator is pressed, the operator presses the opening button of the index finger, and when the speaker emits a "beep" sound, the measurement is completed, and the operator can obtain the liquid crystal from the liquid crystal. The screen shows the measured height value. This operation mode requires two people (ie, the operator and the measured person) to complete, and the measuring unit must be perpendicular to the wall. The actual operation is not easy, and the measurement is not necessary. At the horizontal distance, the first bottom cover is also positioned without the object, so the horizontal distance between the first bottom cover and the object to be tested cannot be accurately measured, and the applicability is obviously insufficient. In addition, it needs to be carried by the user separately, and cannot be used daily. The combination of daily necessities will increase the burden of users.

習知另提供一種如中華民國專利第M414207之「可攜式身高距離量測裝置」,其包含,一本體,係為包具容置空間之殼體,其內設有一電池座;一感應器,係設於本體上方以提供 發射訊號;一接收部,係設於感應器內以接收訊號;一指示器,係設於感應器旁側以提供量測指引;一顯示器,係於本體上方,以提供身高、長度距離與單位顯示;一按鍵A,係設本體之側面以提供第一次測距離之發射與接收;一按鍵B,係設於本體之側面以提供第二次測距離之發射與接收;一單位切換鍵,係設於本體之側面以提供量測尺寸切換;一電路IC板,係設於本體內以提供量測計算、單位及輸出訊號至顯示器;藉之,該可攜式身高距離量測裝置係利用腳到天花板之距離減去頭到天花板的距離,以量測受測者之身高值,惟該本體置於受測者之頭頂時,其接觸面仍有不與重力方向呈垂直之問題,故於自我量測身高時容易產生誤差。 A portable height measuring device as disclosed in the Chinese Patent No. M414207, which comprises a body, a housing having a housing space, a battery holder therein, and a sensor , is provided above the body to provide Transmitting a signal; a receiving portion is disposed in the sensor to receive the signal; an indicator is disposed on the side of the sensor to provide the measurement guide; and a display is disposed above the body to provide the height and length distance and the unit Display; a button A, the side of the body is provided to provide the first measurement and transmission of the distance; a button B is provided on the side of the body to provide the second measurement of the distance of transmission and reception; a unit switch button, The system is disposed on the side of the body to provide measurement and size switching; a circuit IC board is disposed in the body to provide measurement calculation, unit and output signals to the display; thereby, the portable height distance measuring device is utilized The distance from the foot to the ceiling minus the head-to-ceiling distance to measure the height of the subject, but when the body is placed on the top of the subject, the contact surface is still not perpendicular to the direction of gravity, so It is easy to produce errors when self-measuring height.

習知另提供一種如中華民國專利第M252007號「攜帶型身高測量器」,其係藉由該圓球於測量器呈水平靜置時,則該圓球係與正、負極之接點接觸呈導通狀態,進而發射器發出雷射光束,並根據接收器接收到反射後之雷射光束,而計算出使用者實際之身高值,然而槽道內金屬材質所製成之圓球結構容易因環境與操作不當而產生誤判,若於量測之過程而上未放置頭上水平位置之前,該圓球已與正、負極之接點接觸呈導通狀態,此時其旋轉角與俯仰角仍因變動而產生誤差,意即,該圓球於測量器呈縱向之水平靜置方與正、負極之接點接觸呈導通狀態,而於橫向或其他方向之傾斜時,仍無法精確得知該攜帶 型身高測量器是否與重力方向垂直,且其僅能用於高度之量測,仍無法精確量測其與待測物水平之距離,再者,該攜帶型身高測量器需使用者另行攜帶,而無法與日常生活用品結合,將增加使用者於攜帶之困擾,故仍有其不適用之虞。 A conventionally provided, for example, a "portable height measuring device" of the Republic of China Patent No. M252007, wherein the ball is in contact with the contacts of the positive and negative electrodes by the ball being horizontally placed on the measuring device. In the on state, the transmitter emits a laser beam, and according to the receiver receives the reflected laser beam, the actual height value of the user is calculated, but the spherical structure made of the metal material in the channel is easily affected by the environment. If the operation is improper, the misjudgment is caused. If the horizontal position of the head is not placed on the measurement process, the ball is in contact with the contact between the positive and negative poles. At this time, the rotation angle and the elevation angle are still changed. The error is generated, that is, the ball is placed in a horizontal position in the longitudinal direction of the measuring device, and the contact between the positive and negative contacts is in a conducting state, and in the lateral or other direction, the carrying is not accurately known. Whether the height measuring device is perpendicular to the direction of gravity, and it can only be used for height measurement, and the distance between the height measuring device and the object to be tested cannot be accurately measured. Moreover, the portable height measuring device needs to be carried by the user separately. The inability to combine with daily necessities will increase the user's burden of carrying, so there is still a problem that is not applicable.

緣是,本發明係為解決習知尺具難以精確量測長度及距離,且使用者難以自行量測其身高、電磁波之反射之量測裝置於量測使用者身高時,無法確實使電磁波方向與地面垂直而產生誤差等缺失。 The reason is that the present invention is capable of accurately determining the direction of the electromagnetic wave when it is difficult to accurately measure the length and distance of the conventional ruler, and the user is difficult to measure the height and the reflection of the electromagnetic wave by himself. It is perpendicular to the ground and causes errors such as errors.
