Description
本發明係關於一種電子收費異常交易防止方法及防止異常交易的電子收費系統。 The present invention relates to an electronic toll abnormal transaction prevention method and an electronic toll collection system for preventing abnormal transactions.
在傳統的人工收費方式中，因為收費、找零或售、收回數票會消耗相當時間，所以收費站區域一直是高速公路的瓶頸所在，並且因而降低高速公路整體的行車速度。為了改善上述現象，於是發展出利用先進通訊及資訊技術的電子收費系統。 In the traditional manual charging method, since the charging, the change or the sale, and the recovery of the ticket will consume a considerable amount of time, the toll booth area has always been the bottleneck of the expressway, and thus the overall speed of the expressway is reduced. In order to improve the above phenomenon, an electronic toll collection system using advanced communication and information technology has been developed.
目前之電子化自動收費方式之一是採用特定短距通訊技術，利用微波或是無線射頻標籤方式感應扣款，其需用路人安裝設備或標籤，且感應效果易受外界環境偶發性影響而不穩定。另一常見的電子化自動收費方式是利用影像車牌識別，此方式無需用路人安裝設備或標籤，然而，也會受攝影機擺設位置、光源、天候、車牌污損等因素影響識別效果。 One of the current electronic automatic charging methods is to use a specific short-range communication technology to use the microwave or wireless radio frequency tag to sense the deduction. It needs to install equipment or labels by passers-by, and the sensing effect is easily affected by the external environment. stable. Another common electronic automatic charging method is to use image license plate recognition. This method does not need to install equipment or labels by passers-by. However, it also affects the recognition effect by factors such as camera position, light source, weather, and license plate fouling.
上述問題會影響電子化自動收費的可靠性，甚至造成異常交易扣款的問題。習知技術中，在判斷是否異常交易時，是以收費的目標車輛自身的紀錄為基礎，單純檢查目標車輛在特定時間區間內的平均車速是否正常，無客觀標準，有改進的空間。 The above problems will affect the reliability of electronic automatic charging, and even cause the problem of abnormal transaction deduction.

步驟1060，由第一資料獲取裝置獲取在預定時間區間內目 標車輛通過第一位置之目標第一交易時間。舉例而言，本步驟包含由作為第一資料獲取裝置的無線射頻感應裝置，感應在預定時間區間1小時內通過第一位置之目標車輛之無線射頻標籤資料，進而獲得目標車輛通過第一位置之目標第一交易時間。以另一實施例而言，本步驟包含由作為第一資料獲取裝置的影像獲取裝置，獲取在預定時間區間1小時內通過第一位置之目標車輛之車牌影像資料，進而辨識以獲得目標車輛通過第一位置之目標第一交易時間。 Step 1060: The first data acquisition device acquires the target within a predetermined time interval. The target vehicle passes the target of the first position for the first trading time. For example, the step includes: receiving, by the wireless radio frequency sensing device as the first data acquiring device, the radio frequency tag data of the target vehicle passing through the first location within one hour of the predetermined time interval, thereby obtaining the target vehicle passing the first position. Target first trading time. In another embodiment, the step includes: acquiring, by the image acquiring device as the first data acquiring device, the license plate image data of the target vehicle passing through the first position within one hour of the predetermined time interval, thereby identifying the target vehicle through The first trading position of the first position.
在較佳實施例中，目標車輛可屬於前述複數車輛其中之一。 在此情況下，目標第一交易時間屬於複數第一交易時間其中之一。換言之，當步驟1010之由第一資料獲取裝置獲取在預定時間區間內複數車輛通過第一位置之複數第一交易時間完成時，步驟1060之由第一資料獲取裝置獲取在預定時間區間內目標車輛通過第一位置之目標第一交易時間，亦同步完成。然而在不同實施例中，目標車輛不屬於前述複數車輛其中之一。 In a preferred embodiment, the target vehicle may belong to one of the aforementioned plurality of vehicles. In this case, the target first trading time belongs to one of the plural first trading hours. In other words, when the first data acquisition device of step 1010 acquires the plurality of first transaction times of the plurality of vehicles passing the first position within the predetermined time interval, the first data acquisition device of step 1060 acquires the target vehicle within the predetermined time interval. The first trading time through the target of the first position is also completed simultaneously. However, in various embodiments, the target vehicle does not belong to one of the aforementioned plurality of vehicles.
步驟1080，由第二資料獲取裝置獲取目標車輛通過第二位 置之目標第二交易時間。舉例而言，本步驟包含由作為第二資料獲取裝置的無線射頻感應裝置，感應通過第二位置之目標車輛之無線射頻標籤資料，進而獲得目標車輛通過第二位置之目標第二交易時間。以另一實施例而言，本步驟包含由作為第二資料獲取裝置的影像獲取裝置，獲取通過第二位置之目標車輛之車牌影像資料，進而辨識以獲得目標車輛通過第二位置之目標第二交易時間。 Step 1080, obtaining the target vehicle through the second position by the second data acquisition device Set the target second trading time. For example, the step includes: sensing, by the wireless radio frequency sensing device as the second data acquiring device, the radio frequency tag data of the target vehicle passing through the second location, thereby obtaining the target second transaction time of the target vehicle through the second location. In another embodiment, the step includes: acquiring, by the image acquiring device as the second data acquiring device, the license plate image data of the target vehicle passing through the second location, thereby identifying the target vehicle to pass the second position of the target second. transaction hour.
步驟1090，由伺服器根據目標第一交易時間、目標第二交 易時間、以及站間距離計算目標站間速度。 Step 1090, the second transaction is performed by the server according to the target first transaction time and the target Easy time, and distance between stations to calculate the speed between target stations.
步驟1100，當目標站間速度在合理站間速度區間以外，由 伺服器判斷目標第二交易時間為異常交易時間。 Step 1100, when the speed between the target stations is outside the reasonable inter-station speed interval, The server determines that the target second trading time is an abnormal trading time.
進一步而言，習知技術中，在判斷是否異常交易時，是以收 費的目標車輛自身的紀錄為基礎，單純檢查目標車輛在特定時間區間內的平均車速是否正常，無客觀標準。相對的，在本發明的電子收費異常交易防止方法中，因為預在合理站間速度區間的計算基礎是來自預定時間區間內通過第一位置及第二位置的複數車輛而非僅僅基於目標車輛本身，較為客觀。藉此，可客觀有效地防止電子收費異常交易發生。 Further, in the prior art, when determining whether an abnormal transaction is made, Based on the record of the target vehicle itself, it is based on the fact that the average vehicle speed of the target vehicle in a specific time interval is normal, and there is no objective standard. In contrast, in the electronic toll abnormal transaction prevention method of the present invention, since the pre-intermediate inter-station speed interval is calculated based on a plurality of vehicles passing through the first position and the second position within a predetermined time interval, not only based on the target vehicle itself. More objective. Thereby, it is possible to objectively and effectively prevent the occurrence of abnormal electronic transaction transactions.
在一實施例中，預期誤差時間包含獲得自以下步驟：由伺服 器根據第一交易時間、第二交易時間、以及站間距離，計算複數車輛中每一車輛於第一位置及第二位置間的平均速度；由伺服器根據複數車輛中每一車輛於第一位置及第二位置間的平均速度，計算標準差作為標準差時間；以及由伺服器將標準差時間乘以N作為預期誤差時間，其中N為整數。 N較佳等於正負3。進一步而言，藉由此步驟，預期誤差時間可以複數車輛的平均速度為基礎，更具客觀性。 In an embodiment, the expected error time comprises obtaining from the following steps: by servo Calculating an average speed of each vehicle in the plurality of vehicles between the first location and the second location according to the first transaction time, the second transaction time, and the inter-station distance; the server is first according to each vehicle in the plurality of vehicles The average speed between the position and the second position, the standard deviation is calculated as the standard deviation time; and the standard deviation time is multiplied by N by the server as the expected error time, where N is an integer. N is preferably equal to plus or minus 3. Further, by this step, the expected error time can be based on the average speed of the plurality of vehicles, and is more objective.
如圖2所示，在一實施例中，前述步驟1042進一步包含將 複數車輛中每一車輛於第一位置及第二位置間的平均速度依大小分為多組，並且由伺服器根據各組所包含之平均速度計算多組對應的站間速度；步驟1050進一步包含由伺服器根據多組站間速度及預期誤差速度，計算多組合理站間速度區間；以及步驟1100進一步包含當目標站間速度在多組合理站間速度區間以外，由伺服器判斷目標第二交易時間為異常交易時間。 進一步而言，同一路段可能會有不同的車速群組，例如在交流道附近，常見外側因為車輛排隊下交流道而車速最慢，中間車道受其影響車速次之，內側車道受影響較小故車速較快。藉由上述步驟，可區分出多組預期交易時間區間，只要目標第二交易時間位於多組預期交易時間區間其中之一內，即判斷目標車輛在第一位置及第二位置間組成有效旅次。如此，可更貼近真實狀況，避免誤判發生。 As shown in FIG. 2, in an embodiment, the foregoing step 1042 further includes The average speed of each vehicle in the plurality of vehicles between the first position and the second position is divided into a plurality of groups according to the size, and the server calculates a plurality of sets of corresponding inter-station speeds according to the average speed included in each group; step 1050 further includes The multi-combination inter-station speed interval is calculated by the server according to the plurality of inter-station speeds and the expected error speed; and the step 1100 further includes: when the target inter-station speed is in the multi-combination inter-station speed interval, the server determines the target second Trading hours are abnormal trading hours. Further, there may be different speed groups in the same road section. For example, in the vicinity of the interchange, the common side is the slowest because the vehicle is lined up under the interchange, the middle lane is affected by the speed, and the inner lane is less affected. The speed is faster. Through the above steps, multiple sets of expected trading time intervals can be distinguished, as long as the target second trading time is located in one of the plurality of sets of expected trading time intervals, that is, the target vehicle is determined to form an effective travel time between the first position and the second position. . In this way, it can be closer to the real situation and avoid misjudgment.
