藉由該第一收發單元111與該第二收發單元112的設置，且該第一收發單元111與該第二收發單元112是以延長線與該第一定位基站11相連，能進一步延伸該第一定位基站11的接收範圍，並可有效減少發送級數。With the arrangement of the first transceiving unit 111 and the second transceiving unit 112, and the first transceiving unit 111 and the second transceiving unit 112 are connected to the first positioning base station 11 by an extension line, the first transceiving unit can be further extended. A positioning range of the base station 11 can effectively reduce the number of transmission stages.
此外，當該第二定位基站12接收到該第一基站訊號時，該第二定位基站12進一步根據該第一定位基站11發送的第一基站訊號計算一基站訊號強度，且該第二定位基站12發送該第二基站訊號。該第二基站訊號中進一步包含有該基站訊號強度。In addition, when the second positioning base station 12 receives the first base station signal, the second positioning base station 12 further calculates a base station signal strength based on the first base station signal sent by the first positioning base station 11 and the second positioning base station 12 sends the second base station signal. The signal of the second base station further includes the signal strength of the base station.
當該定位伺服器30接收到該第二基站訊號時，該定位伺服器30進一步根據該基站訊號強度判斷是否產生一重新訓練提醒資訊。進一步而言，當該第二定位基站12於接收到該第一基站訊號並計算該基站訊號強度後，將該基站訊號強度傳送至該定位伺服器30，該定位伺服器30判斷該基站訊號強度是否有改變，若有，則該定位伺服器30便可根據判斷結果確認是否要產生該重新訓練提醒資訊。When the positioning server 30 receives the second base station signal, the positioning server 30 further determines whether to generate a retraining reminder information according to the signal strength of the base station. Further, after the second positioning base station 12 receives the signal of the first base station and calculates the signal strength of the base station, it transmits the signal strength of the base station to the positioning server 30, and the positioning server 30 determines the signal strength of the base station Whether there is a change, and if so, the positioning server 30 can confirm whether to generate the retraining reminder information according to the determination result.
亦或是，當該第二定位基站12於接收到該第一基站訊號並計算該基站訊號強度後，能由該第二定位基站12判斷基站訊號強度是否有改變，若有，則將判斷結果發送至該定位伺服器30。而該定位伺服器30便可根據判斷結果確認是否要產生該重新訓練提醒資訊。Or, after the second positioning base station 12 receives the signal of the first base station and calculates the signal strength of the base station, the second positioning base station 12 can determine whether the signal strength of the base station has changed, and if so, the result of the determination Send to the positioning server 30. The positioning server 30 can determine whether to generate the retraining reminder information according to the determination result.
由於室內環境可能改變，如室內的家具移動或新增一道牆，進而導致有障礙物遮蔽，或是因其他施工移動定位器位置，這樣會造成透過樣本比對法進行定位時的誤差，因此，當室內環境改變時，就需要重新進行樣本比對訓練。而該室內定位系統的定位伺服器30能進一步根據該第二基站訊號中的基站訊號強度判斷是否產生該重新訓練提醒資訊來提醒使用者需要重新進行樣本比對訓練。Because the indoor environment may change, such as the movement of indoor furniture or the addition of a wall, which may cause obstructions or move the position of the locator due to other constructions, this may cause errors in positioning by the sample comparison method. Therefore, When the indoor environment changes, it is necessary to re-sample training. The positioning server 30 of the indoor positioning system can further determine whether the retraining reminder information is generated according to the base station signal strength in the second base station signal to remind the user to re-sample training.
因為當室內環境改變時，該第一定位基站11與該第二定位基站12之間的訊號強度也會改變。因此，該定位伺服器30能根據該第二定位基站12接收到的第一基站訊號計算出該基站訊號強度，判斷該基站訊號強度是否改變，藉此確認該第一定位基站11與該第二定位基站12之間的環境是否改變，進而提醒使用者進行樣本比對訓練。Because when the indoor environment changes, the signal strength between the first positioning base station 11 and the second positioning base station 12 also changes. Therefore, the positioning server 30 can calculate the signal strength of the base station based on the signal of the first base station received by the second positioning base station 12 and determine whether the signal strength of the base station has changed, thereby confirming that the first positioning base station 11 and the second base station 11 Whether the environment between the positioning base stations 12 is changed, so as to remind the user to perform sample comparison training.
此外，如圖1所示，當該定位伺服器30接收到該第一基站訊號時，該定位伺服器30亦可進一步根據該第一定位基站11發送的第一基站訊號計算一基站訊號強度，且該定位伺服器30進一步根據該基站訊號強度判斷是否產生一重新訓練提醒資訊。In addition, as shown in FIG. 1, when the positioning server 30 receives the first base station signal, the positioning server 30 may further calculate a base station signal strength based on the first base station signal sent by the first positioning base station 11. And the positioning server 30 further determines whether to generate a retraining reminder information according to the signal strength of the base station.
也就是說，該定位伺服器30能根據接收到的第一基站訊號判斷與該第一定位基站11之間的距離是否被改變，或是之間是否有障礙物阻隔，進而判斷是否要重新進行樣本比對訓練。That is, the positioning server 30 can determine whether the distance from the first positioning base station 11 has been changed or whether there is an obstruction between them according to the received first base station signal, and then determine whether to perform the process again. Sample alignment training.
