Description
本發明係關於一種位置偵測方法，特別為能夠精準掌握無線裝置間位置與距離的無線裝置接近偵測方法。 The invention relates to a position detection method, in particular to a wireless device proximity detection method capable of accurately grasping the position and distance between wireless devices.
現有的偵測無線裝置位置與距離的實際應用技術中，當無線裝置發出之射頻訊號的訊號強度很強時，由於發送射頻訊號之元件本身或環境的磁場與障礙物等影響，造成了射頻訊號的訊號強度與距離的關係值係無任何對應性及相依性，如圖1所示。然而，當無線裝置發出之射頻訊號的訊號強度很微弱時，若以一設定強度門檻值而將射頻訊號加以篩選時，則可以產生射頻訊號的訊號強度與距離的唯一相對應關係，如圖2所示，進而判斷出偵測無線裝置間的位置與距離，但又由於射頻訊號的訊號強度很微弱，故又無法判斷及確定無線裝置是否依然存在於環境間或其狀態，因此，如何藉由調整無線裝置的訊號強度，已達成精準定位，係為各方所欲解決問題。 In the actual application technology for detecting the position and distance of the wireless device, when the signal strength of the RF signal sent by the wireless device is strong, the RF signal is caused by the magnetic field and the obstacle of the component itself or the environment transmitting the RF signal.

However, when the signal strength of the RF signal sent by the wireless device is very weak, if the RF signal is filtered by a set threshold, the unique relationship between the signal strength of the RF signal and the distance can be generated, as shown in FIG. As shown, it is determined that the position and distance between the wireless devices are detected, but because the signal strength of the RF signal is very weak, it is impossible to determine and determine whether the wireless device still exists in the environment or its state, therefore, how to Adjusting the signal strength of the wireless device has achieved accurate positioning, which is the solution for all parties.

請參閱圖8，為本發明之又一種無線裝置接近偵測方法之示意圖，如圖所示，無線訊號發送器100與無線訊號接收器200之間相距一距離，無線訊號發送器100以第一時間間隔的間隔頻率(每1秒1次)同時發出第一訊號、第二訊號及第三訊號，其中第三訊號係與第二訊號、第一訊號同時發送，或此第三訊號與第二訊號交錯輪流與第一訊號同時發送，其中第一訊號發射之訊號強度係為4dBm，第二訊號發射之訊號強度係為-8dBm，第三訊號係發射之訊號強度係為-5dBm，其中無線訊號接收器200之半徑10公尺之範圍為第一範圍300，無線訊號接收器200之半徑3公尺之範圍設為第二範圍400，警示門檻值的訊號強度係為-89dBm，輔助門檻值的接收訊號強度係為-86dBm，以及接近門檻值的接收訊號強度係為-92dBm。無線訊號發送器100朝無線訊號接收器200接近，當無線訊號接收器200收到無線訊號發送器100發送之訊號強度較強的第一訊號時，此時無線訊號接收器200則判斷無線訊號發送器100進入第一範圍300內。當無線訊號接收器200收到無線訊號發送器100發送之第一訊號與第二訊號時，且第二訊號之訊號強度值高於接近門檻值時，表示無線訊號發送器100與無線訊號接收器200之間相距6公尺時，無線訊號接收器200送出一 回饋訊號至無線訊號發送器，無線訊號發送器100接收回饋訊號後，則依據第二時間間隔的間隔頻率(每1秒10次)，發送第二訊號及第三訊號。當無線訊號接收器200收到無線訊號發送器100發送之第一訊號，以及第二訊號或第三訊號其中之一時，且第二訊號的訊號強度高於警示門檻值訊號強度時，或第三訊號的訊號強度高於輔助門檻值訊號強度時，此時無線訊號接收器200則判斷無線訊號發送器100進入第二範圍400內。 Please refer to FIG. 8 , which is a schematic diagram of another method for detecting proximity of a wireless device according to the present invention. As shown, the wireless signal transmitter 100 and the wireless signal receiver 200 are separated by a distance, and the wireless signal transmitter 100 is first. The interval interval (1 time per second) simultaneously sends the first signal, the second signal and the third signal, wherein the third signal is sent simultaneously with the second signal and the first signal, or the third signal and the second signal The signal interleaving is transmitted simultaneously with the first signal, wherein the signal strength of the first signal is 4 dBm, the signal strength of the second signal is -8 dBm, and the signal strength of the third signal is -5 dBm, wherein the wireless signal is The range of the radius of 10 meters of the receiver 200 is the first range 300, and the range of the radius of the wireless signal receiver 200 is set to the second range 400, and the signal strength of the warning threshold is -89 dBm, and the threshold value of the auxiliary threshold is The received signal strength is -86 dBm, and the received signal strength close to the threshold is -92 dBm. The wireless signal receiver 100 approaches the wireless signal receiver 200. When the wireless signal receiver 200 receives the first signal with a strong signal strength sent by the wireless signal transmitter 100, the wireless signal receiver 200 determines the wireless signal transmission. The device 100 enters the first range 300. When the wireless signal receiver 200 receives the first signal and the second signal sent by the wireless signal transmitter 100, and the signal strength value of the second signal is higher than the proximity threshold, the wireless signal transmitter 100 and the wireless signal receiver are indicated. When the distance between the two meters is 6 meters, the wireless signal receiver 200 sends out one The feedback signal is sent to the wireless signal transmitter. After receiving the feedback signal, the wireless signal transmitter 100 transmits the second signal and the third signal according to the interval frequency of the second time interval (10 times per second). When the wireless signal receiver 200 receives the first signal sent by the wireless signal transmitter 100, and one of the second signal or the third signal, and the signal strength of the second signal is higher than the warning threshold signal strength, or the third When the signal strength of the signal is higher than the auxiliary threshold signal strength, the wireless signal receiver 200 determines that the wireless signal transmitter 100 enters the second range 400.
