Description

Processing system and method for route guidance

The invention relates to a digital information processing system and method, and more particularly to a path-guided processing system and method.

For modern people, various means of transportation have become one of the necessities of life. As the types and number of means of transportation continue to grow, limited parking space has become a new problem. Especially for limited places such as stores, if insufficient parking space is set up, it will not only affect the business itself, but also reduce consumers' willingness to repurchase. Moreover, in the parking lot of the store, the driver not only needs to drive while paying attention to whether there are vacant parking spaces. Although there are many guide signs in the parking lot to provide reference for drivers, the guide signs cannot provide relevant information on whether there are parking spaces.

In outdoor parking spaces, you can reach the designated location through the guidance of the Global Positioning System (GPS). However, due to the long response time and insufficient positioning accuracy of commercial GPS systems, the location of the guidance may exceed the range of the parking space, or the vehicle's positioning position may not fall within the parking space. When indoors, the GPS system's signal will be blocked by buildings, causing errors between the vehicle's indoor positioning position and actual position. Therefore, GPS positioning cannot be used in buildings. In addition, although Bluetooth wireless communication can be used for positioning, it is limited by the communication distance, the number of connections that can be made, and the delay of Bluetooth wireless communication, which makes Bluetooth wireless communication unable to be used for guidance in the field.

Please refer to FIG. 1 and FIG. 2 , which are respectively an architectural schematic diagram of a path guidance processing system and a schematic diagram of components of the processing system according to an embodiment. The path guidance processing system is applied in the field 200. The path guidance processing system (hereinafter referred to as the processing system 100) includes an electronic device 110, a plurality of UWB (Ultra-wideband, referred to as UWB) anchor devices 120, and an intermediary controller. 140 and server 150. The field 200 can be, but is not limited to, an indoor parking lot or an outdoor parking lot, and can also be applied in fields that require path guidance, such as stores or office buildings.

The electronic device 110 includes a UWB tag 111, a display unit 112, a first communication unit 113, a first storage unit 114 and a first processing unit 115. The electronic device 110 may be, but is not limited to, a mobile phone, a tablet computer, a notebook computer or an electric vehicle. The first processing unit 115 is connected to the UWB tag 111 , the display unit 112 , the first communication unit 113 and the first storage unit 114 . The first storage unit 114 stores the access program 116 and user information 117 . The first processing unit 115 executes the access program 116. The access program 116 causes the first processing unit 115 to drive the display unit 112 to play the guidance information 166 based on the obtained guidance information 166 . The user information 117 corresponds to the universally unique identifier (UUID), phone number, ID number, registered member account or media control access code (MAC) of the electronic device 110. wait.

The generation and processing of the guidance information 166 will be described in detail later. When the electronic device enters the field 200, the first processing unit 115 drives the UWB tag 111 to send a pulse signal 161, and the UWB anchor device 120 receives the pulse signal 161 sent by the electronic device. Or the UWB tag 111 receives the pulse signal 161 of the UWB anchor device 120. The first communication unit 113 is connected to the server 150 through a network. In addition to being connected to the server 150 through the IEEE802.1X series of network communication protocols, the first communication unit 113 can also be connected to the server 150 using a mobile communication network (such as General Packet Radio Service, 4th generation mobile networks or 5th generation wireless system).

The UWB anchor device 120 has a second communication unit 121, an antenna unit 122, a second storage unit 123 and a second processing unit 124. The second processing unit 124 is connected to the antenna unit 122 and the second storage unit 123. The antenna unit 122 transmits or receives a pulse signal 161. The second processing unit 124 performs time to flight (ToF), time difference of arrival (TDOA) positioning, time of arrival (TOA) positioning, two way ranging (TWR), received signal strength indicator (RSSI) or angle of arrival (AOA) positioning on the received pulse signal 161.

The second processing unit 124 generates a preamble signal 162 according to the received pulse signal 161. The second communication unit 121 transmits the preamble signal 162 to the intermediate controller 140. The second storage unit 123 can temporarily store the pulse signals 161 of different UWB tags 111.

For the sake of convenience, only a single UWB anchor device 120 is used for illustration in FIG2 , but the number is not limited to this. A plurality of UWB anchor devices 120 and at least one intermediate controller 140 are arranged in the field 200. The server 150 can be selectively arranged in the field 200, or configured as a cloud server. To distinguish between UWB anchor devices 120 that have received the pulse signal 161 and those that have not received the pulse signal 161. In the following, the UWB anchor device 120 that has received the pulse signal 161 is referred to as a matching anchor device 130, and the rest that have not received the pulse signal are still referred to as UWB anchor devices 120, as shown in FIG1 .

The intermediary controller 140 is connected to the server 150 and all the UWB anchor devices 120 in the field 200. The matching anchor device 130 sends the preamble 162 to the intermediary controller 140. The intermediary controller 140 generates corresponding location information 163 according to the preamble 162 of at least three matching anchor devices 130. The number of intermediary controllers 140 to be configured can be determined according to the area or floor, for example, different floors are respectively configured with corresponding intermediary controllers 140. In FIG. 1, the intermediary controller 140 is used as an example to connect all the UWB anchor devices 120.

The server 150 has a third communication unit 151, a third storage unit 152 and a third processing unit 153. The third processing unit 153 is connected to the third communication unit 151 and the third storage unit 152. The third communication unit 151 is connected to the electronic device 110 and the UWB anchor device 120 through the aforementioned network. The third communication unit 151 transmits location information 163, guidance information 166 or other operation requirements. The third storage unit 152 stores path information 164 and idle location information 165 of the field 200.

Generally speaking, there are a plurality of vacant locations 211 (e.g., vacant parking spaces and paths (without numbers)) in the venue 200. When the vacant location 211 is not specified, the coordinates of the vacant locations 211 (vacant parking spaces) in the venue 200 may be collectively referred to as vacant location information 165. For any vacant location 211, the electronic device 110 may reach the specified vacant location 211 via the path set planned by the server 150. The coordinates of the path set are collectively referred to as is the path information 164. In the following description, for the designated vacant position 211, the vacant position information 165 is the coordinate of the designated vacant position 211. The site 200 is a parking lot, for example, the vacant position 211 is a parking space, and the vacant position information 165 is the spatial coordinate of the parking space. The path is a lane of the parking lot, and the path information 164 is a coordinate set of the lane of the parking lot. Alternatively, if the site 200 is a department store, the store between the floors is the vacant position 211.

When the free position 211 is used (or occupied), the third processing unit 153 marks the free position 211 as the used space 212. In other words, the third processing unit 153 selects any one of all the free positions 211 as the target position 213. The third processing unit 153 generates the guidance information 166 according to the position information 163, the path information 164 and the free position information 165. After the target position 213 is used, the server 150 marks the target position 213 as the used space 212. The third processing unit 153 drives the third communication unit 151 to transmit the guide information 166 to the electronic device 110 , and the display unit 112 of the electronic device 110 displays the guide information 166 , so that the user can conveniently drive directly to the vacant location 211 through the guide information 166 .

In some embodiments, the intermediate controller 140 may be disposed in the server 150 so that the server 150 may directly obtain the location information 163 based on the preamble 162.

To further explain the overall operation process of the processing system 100, please refer to the path guidance processing method of Figure 3. The path guidance processing method includes the following steps: Step S310: Set up multiple UWB anchor devices in the field; Step S320: The electronic device drives the UWB tag to send a pulse signal; Step S330: The UWB anchor device that obtains the pulse signal is a matching anchor device; Step S340: When the intermediate controller obtains the preamble signals of at least three matching anchor devices, the intermediate controller generates location information according to the preamble signals; Step S350: The intermediate controller transmits the location information to the server; Step S360: The server matches the location information with a plurality of free location information and selects at least one of the free location information as the target location; Step S370: The server generates guidance information based on the location information and the target location; and Step S380: The server transmits the guidance information to the electronic device.

First, multiple UWB anchor devices 120 are set in the field 200, and the UWB anchor devices 120 are enabled (corresponding to step S310), so that the UWB anchor devices 120 are connected to the intermediate controller 140. The intermediate controller 140 is electrically connected to the server 150. When the electronic device 110 enters the field 200, the UWB tag 111 of the electronic device 110 broadcasts the pulse signal 161 (corresponding to step S320). At the same time, the electronic device 110 executes the access program 116. The access program 116 can be connected to the server 150 via a network. The server 150 can verify the membership qualification, push the route, or payment information of the connected access program 116. The access program 116 can also be used to play the guidance information 166, wherein the access program 116 can draw relevant prompt graphics in the display unit 112, or drive the built-in speaker or Bluetooth headset to send prompt audio.

In the transmission range of the pulse signal 161 of the UWB tag 111, the UWB anchor device 120 receiving the pulse signal 161 is regarded as the matching anchor device 130 (corresponding to step S330). When the matching anchor device 130 leaves the transmission range of the pulse signal 161, the aforementioned matching anchor device 130 will be restored to the UWB anchor device 120.

Similarly, the signal transmission and reception range of the UWB anchor device 120 can also be adjusted. The matching anchor device 130 sends a preamble signal 162 to the intermediate controller 140 according to the pulse signal 161. The preamble signal 162 records the relevant information of the UWB tag 111 of the electronic device 110, such as: tag identity (ID), distance, transmission time, or user membership information.

When the intermediary controller 140 receives the preamble signal 162 of the matching anchor device 130, the intermediary controller 140 determines the number of matching anchor devices 130 of the same electronic device 110 based on the preamble signal 162. If the number of matching anchor devices 130 belonging to the same electronic device 110 is greater than three, the intermediary controller 140 obtains the location information 163 of the corresponding electronic device 110 based on the preamble signal 162 (corresponding to step S340). The intermediary controller 140 obtains the location coordinates of the electronic device 110 in the field 200 (i.e., the location information 163) based on the preamble signals 162 at different locations and the triangulation positioning calculation. In addition, the intermediary controller 140 can also calculate the location information 163 of the electronic device 110 through the aforementioned RSSI, AOA, or TOA.

The intermediary controller 140 transmits the location information 163 to the server 150 (corresponding to step S350). The server 150 searches for free location information 165 based on the location information 163. The server 150 can match the location information 163 with the shortest path of the free location information 165, or select the free location information 165 that meets the conditions set by the access program 116, such as specifying a relevant floor or range. The server 150 selects at least one free location 211 from the free location information 165, and the selected free location 211 is regarded as the target location 213 (corresponding to step S360).

The server 150 selects corresponding path information 164 according to the target location 213 and the location information 163, and packages the selected path information 164 and the target location 213 into guidance information 166. In addition to selecting the target location 213 by the shortest path, the server 150 can also use the shortest time or generate the corresponding guidance information 166 with the target location 213 specified by the electronic device 110 (corresponding to step S370).

The server 150 transmits the guidance information 166 to the electronic device 110 (corresponding to step S380). The electronic device 110 receives the guidance information 166, and the access program 116 plays the guidance information 166 on the display unit 112, as shown in FIG4. In FIG4 and FIG5, a parking lot is used as the field 200 and the electronic device 110 is a mobile phone as an example. In addition, the electronic device 110 is located in a vehicle vehicle, so in FIG4 and FIG5, the vehicle vehicle is regarded as equivalent to the electronic device 110. The outer dotted circle of the electronic device 110 represents the signal range of the pulse signal 161. The coordinates of the vehicle position in the field 200 are the position information 163.

4 shows an example of the arrangement of the vacant locations 211 and the UWB anchor devices 120 in the field 200. However, the above-described arrangement example is for illustration only, and the number and positions of the vacant locations 211 and the number and arrangement positions of the UWB anchor devices 120 are not limited thereto.

In FIG5 , the access program 116 plays the field 200 (corresponding to the aforementioned parking lot) and the guidance information 166. The parking spaces in FIG5 can be viewed as free positions 211 (indicated by white squares), the used free positions 211 are represented by dark gray squares (i.e., used spaces 212), and the free positions 211 of light gray squares are represented as target positions 213. When the electronic device 110 enters the field 200, the UWB tag 111 sends a pulse signal 161 to the matching anchor device 130, so that the intermediate controller 140 generates the location information 163 of the electronic device 110. Then, the server 150 receives the location information 163 of the intermediate controller 140. The server 150 selects the target location 213 from the free location information 165 according to the location information 163. In FIG5 , the free location 211 to which the electronic device 110 is closest is used as the selection basis.

The server 150 selects a corresponding set of path information 164 according to the target location 213 and generates corresponding guidance information 166. The server 150 sends the guidance information 166 to the electronic device 110. The electronic device 110 plays the lanes and guidance information 166 of the venue 200 for the user to use as a reference for driving. When the electronic device 110 reaches the target location 213, the user stops the vehicle at the target location 213, and the user can take the electronic device 110 with him to temporarily leave the venue 200.

In some embodiments, each free position 211 is provided with a detection device 610. The detection device 610 is electrically connected to the server 150, as shown in FIG6 . The detection device 610 may be a ground pressure sensor, a camera, or an infrared detector, etc. Taking the ground pressure sensor as an example of the detection device 610, when the electronic device 110 (i.e., a vehicle vehicle) arrives at the target position 213, the vehicle vehicle presses against the ground pressure sensor, causing the ground pressure sensor to send a trigger signal to the server 150. The server 150 records that the target position 213 has been used (i.e., the used space 212 mentioned above) according to the trigger signal. The server 150 records the start time of use of the target position 213. Alternatively, the detection device 610 is a camera, which can take a picture of the vacant location 211. If a vehicle exists, the camera sends a trigger signal to the server 150.

After the vehicle leaves the target location 213, the detection device 610 will be released. Therefore, the detection device 610 stops sending the trigger signal to the server 150. Therefore, the server 150 can use the time of receiving the trigger signal as the usage time of the target location 213. The server 150 matches the tag identity or member registration information in the location information 163 with the target location 213 and its usage time. The server 150 calculates the corresponding processing fee based on the usage time of the target location 213. Taking the aforementioned parking lot as an example, the server 150 can calculate the usage time of the vehicle using the target location 213 and calculate the corresponding parking fee.

In some embodiments, the processing system 100 further includes at least one gate anchor device 810, see FIGS. 7 and 8. The gate anchor device 810 and the UWB anchor device 120 have the same components and structure, so the structural description of the gate anchor device 810 is not repeated. Compared with the UWB anchor device 120, the detection range of the gate anchor device 810 for the pulse signal 161 is smaller than the detection range of the UWB anchor device 120. The gate anchor device 810 is also connected to the intermediate controller 140. The gate anchor device 810 is set at the entrance and exit of the field 200. When the electronic device 110 enters or exits the venue 200 , the electronic device 110 needs to be close to the gate anchor device 810 in order to send the pulse signal 161 to the gate anchor device 810 .

The gate anchor device 810 generates a corresponding preamble signal 162 according to the pulse signal 161. In order to distinguish the preamble signal 162 of the electronic device 110 entering or exiting the field, the preamble signal 162 when the electronic device 110 enters the field 200 is referred to as the field entry signal 171, and the preamble signal 162 when the electronic device 110 leaves the field 200 is referred to as the field exit signal 172. The intermediate controller 140 forwards the field entry signal 171 (or the field exit signal 172) to the server 150.

The server 150 determines whether the electronic device 110 has entered or exited the field 200 within a time period as the field entry signal 171 or the field exit signal 172. Regardless of whether the electronic device 110 enters the field 200 for the first time or enters the field 200 again, the gate anchor device 810 transmits the field entry signal 171 to the intermediate controller 140. The gate anchor device 810 sends a notification signal to the electronic device 110, so that the electronic device 110 executes the access program 116 and obtains the guidance information 166.

Or in some embodiments, the processing system 100 further includes a UWB peripheral tag 710, as shown in FIG9 . After the user obtains the UWB peripheral tag 710, the user copies and records the user information 117 in the UWB peripheral tag 710 through the UWB tag 111 of the electronic device 110. The user can obtain the UWB peripheral tag 710 when entering the venue 200, for example, from an automated teller device (Point of Sale, POS) or a counter when passing through a gate anchor device 810. The UWB peripheral tag 710 can be an independent tag (TAG) element or an electronic device 110 with a UWB communication protocol. In this embodiment, the user can place the UWB peripheral tag 710 in the target location 213. In other words, when the vehicle vehicle is parked at the target location 213, the user can take the electronic device 110 away from the target location 213 and place the UWB peripheral tag 710 instead of the electronic device 110 in the vehicle vehicle (ie, in the target location 213).

If the user places the electronic device 110 (or the UWB peripheral tag 710) at an idle position 211 outside the target position 213, the processing system 100 regards this idle position 211 as a pause position. When the user and the electronic device 110 leave the field 200, the gate anchor device 810 transmits a field exit signal 172 to the intermediate controller 140. At the same time, the UWB peripheral tag 710 located at the pause position and its matching anchor device 130 transmit a preamble signal 162 to the intermediate controller 140. The intermediate controller 140 obtains a peripheral location information 711 of the UWB peripheral tag 710. The intermediate controller 140 transmits the peripheral location information 711 to the server 150. The server 150 records the pause position as the target position 213 according to the field leaving signal 172 and the peripheral device position information 711.

In some embodiments, when the electronic device 110 enters the field 200 again, the electronic device 110 obtains corresponding guidance information from the server 150 by matching the anchor device 130. The server 150 can determine whether there is a used target location 213 in the field 200 according to the tag identity of the field login signal 171. Since the electronic device 110 enters the field 200 again, the server 150 has recorded the tag identity of the UWB tag 111 and obtains the target location 213 from the server 150. In addition, the server 150 can also obtain the target location 213 through the UWB peripheral tag 710. Therefore, the server 150 generates corresponding guidance information 166 according to the UWB tag 111 and the target location 213 (corresponding to the UWB peripheral tag 710). The server 150 sends the guidance information 166 to the electronic device 110 to provide the user with reference information for traveling to the target location 213. The process can refer to the action sequence of FIG. 8 .

After the user arrives at the target location 213, the user can choose to drive out of the venue 200. When the user leaves the venue 200 and the electronic device 110 passes through the gate anchor device 810, the server 150 will also receive the venue exit signal 172 sent by the intermediary controller 140. The server 150 obtains the actual usage time of the electronic device 110 in the venue 200 based on the start time of the target location 213 and the generation time of the venue exit signal 172. At the same time, the server 150 can calculate the corresponding service fee based on the actual usage time. If the electronic device 110 and the server 150 have been bound to the online money flow service, the server 150 can send the corresponding fee payment request to the online money flow server. The user can confirm the fee by accessing the program 116, thereby saving the user the time of finding the payment site and making the payment.

In some embodiments, the server 150 selects adjacent idle locations 211 from the field 200 based on the location information 163. In other words, the server 150 selects at least two adjacent idle locations 211 as the target location 213. The information set of multiple idle locations 211 is referred to as target area information (unlabeled) herein. The server 150 generates guidance information 166 based on the target area information. When the electronic device 110 arrives at the set of selected idle locations 211, the user can select any idle location 211 from the set of idle locations 211 as the target location 213. Taking FIG. 5 as an example, the server 150 can select multiple and adjacent idle locations 211 in the lower right corner of FIG. 5 as the target area information. The server 150 encapsulates the target area information into the guidance information 166 and sends it to the electronic device 110. The server 150 selects a target area (ie, target area information) of a corresponding size from the field 200 according to different plans for use by a single user or multiple users.

The processing system 100 and method for route guidance are applied in a field 200 to provide route guidance for users when traveling. Whether the user enters the field 200 for the first time or re-enters the field 200, different UWB devices can be used to locate and obtain guidance information 166. When the user drives away from the field 200, the processing system 100 can calculate the consumption fee based on the usage time of the target location 213. In addition, the processing system 100 can also be combined with online money flow services. After the electronic device 110 receives the relevant fees sent by the server 150, the electronic device 110 and the online money flow process the deduction.
