接續上述內容進一步詳述本創作之實施方式，首先為不影響複數指向性收音單元(15A、15B、15C、15D)的收音效果，因此以偵測器1底部14安置於車頂是較為恰當的，顯示器2則是放置於駕駛者方便觀看之位置即可，首先看向第三圖，由於所有指向性收音單元(15A、15B、15C、15D)僅能接收與自身收音側151同一側的聲音，因此聲音數據庫17所儲存的聲音的方向判斷數據為：指向性收音單元15A收到聲音，即是鳴笛聲來自前方；指向性收音單元15B收到聲音，即是鳴笛聲來自右側，指向性收音單元15C收到聲音，即是鳴笛聲來自後方，指向性收音單元15D收到聲音，即是鳴笛聲來自左側，另聲音數據庫17所儲存的各類型鳴笛車聲波數據包括有警車、消防車、救護車等，接續如第四圖所呈現，舉例一種本實施例的應用情境，可以看見警車100在於安裝有偵測器1的車輛後方，因此鳴笛聲也會來自偵測器1後方，而偵測器1的指向性收音單元15C即會收到此一鳴笛聲，而運算單元16會將各複數指向性收音單元(15A、15B、15C、15D)所偵測之聲音數據比對該聲音數據庫17內部的數據，運算出鳴笛車類型為警車100且來自後方的結果數據，而結果數據會經由無線傳輸單元18傳輸至顯示器2的無線接收單元22，處理單元21將結果數據處理完後便會如第五圖所呈現，經由提示顯示區23顯示提示訊息，綜合前述所有內容可以得知，本發明確實得以偵測鳴笛車的鳴笛聲方向，以判斷出鳴笛車的方位，並顯示提示訊息，以供駕駛第一時間做出正確的讓道動作，確實解決了習知行駛中不易判斷鳴笛車方向的問題。Continuing the above content to further detail the implementation of this creation, first of all, it does not affect the radio effect of the plural directional radio units (15A, 15B, 15C, 15D), so it is more appropriate to place the bottom 14 of the detector 1 on the roof of the car. , The display 2 can be placed in a position that is convenient for the driver to view. First, look at the third picture, because all the directional radio units (15A, 15B, 15C, 15D) can only receive the sound from the same side as the own radio side 151 Therefore, the sound direction judgment data stored in the sound database 17 is: the directional radio unit 15A receives the sound, that is, the horn sound comes from the front; the directional radio unit 15B receives the sound, that is, the horn sound comes from the right side and points to The sound received by the sex radio unit 15C is the sound of the whistle from the rear, and the directional radio unit 15D receives the sound, that is, the sound of the whistle comes from the left side. In addition, the sound wave data of various types of whistling cars stored in the sound database 17 includes police cars. , Fire trucks, ambulances, etc., continue as shown in the fourth figure. For an example of an application scenario of this embodiment, it can be seen that the police car 100 is behind the vehicle where the detector 1 is installed, so the whistle sound will also come from the detector At the rear of 1, the directional radio unit 15C of the detector 1 will receive this whistle sound, and the computing unit 16 will detect the sound of the plural directional radio units (15A, 15B, 15C, 15D) The data is compared with the internal data of the sound database 17, and the result data of the horn car type being police car 100 and coming from the rear is calculated, and the result data will be transmitted to the wireless receiving unit 22 of the display 2 via the wireless transmission unit 18, and the processing unit 21 will After the result data is processed, it will be as shown in the fifth figure. The prompt message is displayed through the prompt display area 23. It can be known from all the foregoing that the present invention can indeed detect the direction of the whistle sound of the whistle car to determine the whistle. The direction of the whistle car is displayed and a prompt message is displayed for the driver to make the correct way to give way at the first time, which indeed solves the problem that it is difficult to judge the direction of the whistle car during conventional driving.

其中該聲音數據庫17儲存有各類型鳴笛車的聲波音量數據，用以該運算單元16將各複數指向性收音單元15所偵測之聲音數據比對該聲音數據庫17內部的聲波音量數據，進而運算判斷出鳴笛車之距離並彙整至結果數據內，如第六圖、第七圖所呈現，進一步提示顯示區23還顯示了鳴笛車(消防車200)的距離，以供駕駛更為精準的判斷讓道時機。The sound database 17 stores the sound volume data of various types of whistling cars, and the computing unit 16 compares the sound data detected by the plural directional radio units 15 with the sound volume data inside the sound database 17, and then The calculation determines the distance of the whistle vehicle and integrates it into the result data, as shown in the sixth and seventh graphs. It is further prompted that the display area 23 also displays the distance of the whistle vehicle (fire engine 200) for further driving. Accurate judgment gives way to timing.

本發明另提供有一實施例，如第八圖至第十一圖所呈現，與前一實施例主要差別在於並無匹配有顯示器，但另具有發聲單元36用以發出提示音，相比前一實施例更適合是配戴於駕駛身上，如第十圖所呈現，舉例一種此一實施例的應用情境，聲音數據庫34聲音的方向判斷數據所記錄之內容以指向性收音單元32a收到聲音，即是鳴笛聲來自前方；指向性收音單元32b收到聲音，即是鳴笛聲來自前右側，指向性收音單元32c收到聲音，即是鳴笛聲來自後方，指向性收音單元15d收到聲音，即是鳴笛聲來自左側為例子，而圖中所示消防車200是位於本發明左側，因此是指向性收音單元32d接收到鳴笛聲，而運算單元33比對各指向性收音單元(32a、32b、32c、32d、32e、32f)所偵測之聲音數據比對該聲音數據庫34內部的數據，而運算出數據以供發聲單元36發出提示音，例如「消防車來自左側」此類可明確提示鳴笛車類型與方位的提示音，另外由於此一實施例屬於攜帶型的，相較於前一實施例的偵測器固定設置不同，會因為配戴部位的位移(例如：手錶式配戴)而使得各指向性收音單元(32a、32b、32c、32d、32e、32f)不一定是對準預設方向，舉個例子，如第十一圖所示，對準左側的是指向性收音單元32e，因此會變成指向性收音單元32e接收到鳴笛聲，運算單元33理應無法正確運算出鳴笛聲來自左側，但此一實施例還設置有陀螺儀35，運算單元33可依照該陀螺儀35偏轉角度校正出正確的鳴笛聲方向，以使此一實施例無論如何偏轉，皆可以發出正確的提示音。The present invention provides another embodiment, as shown in Figs. 8 to 11. The main difference from the previous embodiment is that it does not have a display, but it also has a sound unit 36 to emit a prompt sound. Compared with the previous The embodiment is more suitable to be worn on the driver. As shown in Figure 10, for example an application scenario of this embodiment, the content recorded by the sound direction judgment data of the sound database 34 is received by the directional radio unit 32a. That is, the horn sound comes from the front; the directional radio unit 32b receives the sound, that is, the horn sound comes from the front right side, the directional radio unit 32c receives the sound, that is, the horn sound comes from the rear, and the directional radio unit 15d receives the sound. The sound, that is, the whistle sound comes from the left side as an example, and the fire truck 200 shown in the figure is located on the left side of the present invention, so the directional radio unit 32d receives the whistle sound, and the computing unit 33 compares each directional radio unit (32a, 32b, 32c, 32d, 32e, 32f) The detected sound data is compared with the data inside the sound database 34, and the data is calculated for the sound unit 36 to emit a prompt sound, such as "Fire truck from the left" Class can clearly indicate the type and position of the whistle car. In addition, because this embodiment is a portable type, it is different from the fixed setting of the detector in the previous embodiment because of the displacement of the wearing part (for example: Watch-style wear) so that the directional radio units (32a, 32b, 32c, 32d, 32e, 32f) are not necessarily aligned with the preset direction. For example, as shown in the eleventh picture, aligned with the left It is the directional radio unit 32e, so it becomes that the directional radio unit 32e receives the whistle sound. The calculation unit 33 should not be able to correctly calculate that the whistle sound comes from the left side. However, this embodiment is also provided with a gyroscope 35 and a calculation unit 33 The correct direction of the whistle sound can be corrected according to the deflection angle of the gyroscope 35, so that this embodiment can emit the correct prompt sound regardless of the deflection.

其中該聲音數據庫34儲存有各類型鳴笛車的聲波音量數據，用以該運算單元33將各複數指向性收音單元(32a、32b、32c、32d、32e、32f)所偵測之聲音數據比對該聲音數據庫34內部的聲波音量數據，進而運算判斷出鳴笛車之距離並彙整至判斷數據內，以使提示音進一步提供距離的提示，例如「消防車來自左側10公尺處」的提示音，以供駕駛更為精準的判斷讓道時機。The sound database 34 stores the sound volume data of various types of whistling cars, and the calculation unit 33 compares the sound data detected by the plural directional radio units (32a, 32b, 32c, 32d, 32e, 32f) The sound volume data inside the sound database 34 is then calculated to determine the distance of the whistling vehicle and aggregated into the judgment data, so that the prompt sound provides further distance prompts, such as the prompt "The fire truck is 10 meters from the left" Sound for the driver to judge the timing of giving way more accurately.
