Referring to fig. 1, fig. 1 shows a terminal device 100 according to a first embodiment of the present invention, optionally, the terminal device 100 may be a mobile phone, a notebook, a tablet computer, and the like, and the device includes:

the detecting element 110 is configured to detect a trigger for performing a navigation service.

Specifically, the user may click a navigation control in the terminal application, and then the navigation service is triggered.

The transceiver 120 is configured to generate first indication information according to the trigger information, and send the first indication information to a cloud platform, where the first indication information is used to indicate that a navigation service needs to be performed.

Specifically, when the signal of the cellular network is good, the first indication information may be sent to the cloud platform through the cellular network after the first indication information is generated. The transceiver may be a transceiver with information processing capabilities.

The first indication information may include one of the following information: identity information of the terminal and a current location of the terminal; and identity information of the terminal. For example, if the repository has a plurality of entries, the first indication information may include identity information of the terminal and a current location of the terminal; if the repository has only one entry, the first indication information may include identity information of the terminal. After receiving the identity information of the terminal in the first indication information, the cloud platform records the identity information of the terminal and marks that the navigation service is being used. Optionally, the first indication information may further include identification information of a target charging pile, where the position of the target charging pile is a navigation destination, and the target charging pile may be specified by a user. Optionally, when the first indication information does not include the identification information of the target charging pile, the target charging pile may be considered as the charging pile being used by the user.

The transceiver 120 is further configured to receive a navigation route map sent by the cloud platform, where the navigation route map is generated according to the first indication information and the charging pile distribution of the navigation target area.

The cloud platform stores a simple plane structure of the warehouse and distribution of charging piles, generates a navigation route map according to the first indication information and the charging pile distribution of a navigation target area after receiving the first indication information, and sends the navigation route map to the terminal, wherein the navigation route map is from a warehouse entrance to a charging pile used by a user or from the warehouse entrance to a charging pile designated by the user.

And the display 130 displays the navigation route map and indicates the position of the terminal according to the position of the charging pile.

Optionally, as shown in fig. 2, the navigation route map includes at least one of the following information:

a traveling direction indicator 203 and at least one position indicator 202, wherein the position indicator 202 corresponds to the charging pile 201. The travel direction indicator 203 is used to indicate the direction of travel for the user, and the position indicator 202 is used to indicate the position of the terminal for the user.

The position indicator 202 is optional, the charging pile 201 is also optional, the position of the terminal may be indicated only by the position indicator 202, the position of the terminal may be indicated only by the identifier 201 of the charging pile in fig. 2, or the position of the terminal may be indicated by using both the position indicator 202 and the identifier 201 of the charging pile.

Specifically, as shown in fig. 2, when a user travels along a route and a direction in a navigation roadmap, a terminal of the user enters a bluetooth service range of a charging pile, and a bluetooth connection element of the terminal sends a bluetooth connection request to the charging pile, where the connection request includes identity information of the terminal. The charging pile sends the identity information of the terminal to a cloud platform, the cloud platform judges whether the identity information of the terminal in the received first indication information is consistent with the identity information of the terminal connected with the Bluetooth, if so, second indication information is generated and used for indicating a position indication mark corresponding to the charging pile to indicate the position of the terminal, the cloud platform sends the second indication information to the charging pile, and the charging pile sends the second indication information to the terminal through the Bluetooth connection.

The position indication mark indicates the position of the terminal, including: the position indicator indicates the position of the terminal by one of the following ways: lighting, blinking, shape change, and changing colors. For example, when the terminal establishes a bluetooth connection with the charging pile kk and receives the second indication information from the charging pile kk, the position indication mark k corresponding to the charging pile kk may turn bright blue, while other position indication marks may be gray, or the position indication mark k may turn a flash from colorless to bright blue, or the position indication mark k may turn from a circular point to another shape, or the position indication mark k may turn a circle of animation of a circle spreading outward.

Optionally, the bluetooth connection element is specifically configured to search for a bluetooth signal that can be received, select a charging pile with the largest bluetooth signal intensity, and send a bluetooth connection request to the charging pile, where the connection request includes the identity information of the terminal. Illustratively, when the bluetooth signals of the charging pile nn and the charging pile kk are finally searched, comparing the bluetooth signal intensities of the charging pile nn and the charging pile kk, and if the bluetooth signal intensity of the charging pile kk is higher, sending a bluetooth connection request to the charging pile kk.

Optionally, the bluetooth connection element is further configured to, when the bluetooth signal strength of another charging pile is found to be highest, disconnect the bluetooth connection with the currently connected charging pile and connect another charging pile with the highest bluetooth signal strength; the transceiver is further configured to receive third indication information through the bluetooth connection of the another charging pile, where the third indication information is used to indicate that the location indication mark corresponding to the another charging pile indicates the location of the terminal. The third indication information is further used for indicating that the position indication mark which does not correspond to the other charging pile restores the state of not indicating the position of the terminal. Illustratively, when the terminal has established a bluetooth connection with the charging pile kk, and when the terminal searches that the bluetooth signal of the charging pile nn is the largest of all the searched bluetooth signals, the terminal disconnects the bluetooth connection with the charging pile kk and sends a bluetooth connection request to the charging pile nn. After the terminal establishes bluetooth connection with the charging pile nn, the third indication information sent by the charging pile nn is received, and the position indication mark n indicates the position of the terminal through lighting, flickering, shape change or color change. Optionally, after receiving the third indication information, the terminal returns the position indication mark k to a state that does not indicate the position of the terminal, such as returning to gray; or when the charging pile kk is disconnected, the position indication mark k returns to a state of not indicating the position of the terminal, such as returning to grey. Optionally, the second indication information and the third indication information may be information of the same structure, and in this embodiment, the second indication information and the third indication information are only information for distinguishing between different charging piles. Optionally, the second indication information is further used to indicate that the position indication mark not corresponding to the charging pile is restored to a state of not indicating the position of the terminal.

Optionally, the apparatus further comprises a determining element; the transceiver is further configured to receive a navigation target area map sent by the cloud platform, as shown in fig. 2, where the map includes a location 201 of the charging pile and a location indicator 202 corresponding to the charging pile; and the judgment element is used for determining that the position indication mark corresponding to the charging pile connected through the Bluetooth is not on the navigation route map and giving an alarm. Specifically, the cloud platform may send a map of the navigation target area to the terminal according to the navigation target area of the terminal after receiving the first indication information sent by the terminal. After the transceiver of the terminal receives the navigation route map and after the terminal establishes Bluetooth connection with the charging pile mm, the terminal judges that the position indication mark m corresponding to the charging pile mm is not on the navigation route map, or the cloud platform judges that the position indication mark m corresponding to the charging pile mm is not on the navigation route map, and the judgment element of the terminal gives an alarm, and if a pop-up window prompts deviation from the navigation route.

Specifically, the cloud platform may specifically generate the navigation roadmap by:

determining an initial position A and a target position indicator mark S of navigation, determining a weighting coefficient between a position indicator mark n and a position indicator mark k on a navigation route, and calculating a weighted distance from the position indicator mark n to the initial position A according to the weighting coefficient;

calculating a comprehensive evaluation function F (n) according to the weighted distance from the position indicator n on the navigation route to the initial position;

and selecting the position indication marks forming the navigation route map according to the comprehensive evaluation function F (n).

The weighting coefficient D (n, k) between the position indicator n and the last position indicator k is: d (n, k) ═ 1+ log_HasH (n, k), where Has is the manhattan distance from the initial position a to the target position-indicating marker S, and H (n, k) is the manhattan distance between the position-indicating marker n and the position-indicating marker k. As in fig. 2, the manhattan distance H (k, n) ═ abs (k.x-n.x) + abs (k.y-n.y) from position indicator k (k.x, k.y) to position indicator n (n.x, n.y), where abs is a function of absolute value. The purpose of using the log function is to amplify the coefficient quickly and increase the sensitivity when the distance is relatively small compared to the change of Has.

The weighted distance G (n, A) from the position indicator n to the initial position A is: g (n, a) ═ G (k, a) + D (n, k) × H (n, k), where G (k, a) is the weighted distance from the initial position a to the position indicator k;

if the position indicator n is reached from the initial position a via the position indicator k, the position indicator k can be defined as the parent node of the position indicator n, and the comprehensive valuation function f (n) of the position indicator n is: f (n) + H (n, S), where H (n, S) is the manhattan distance of the position indication mark n to the target position indication mark S.

Specifically, the navigation route map may be generated by:

adding the initial position A point into a path planning search table, and circularly traversing the following actions:

traversing the path planning search table, finding the initial position or position indication mark which enables the F to be minimum as a current node, and putting the initial position or position indication mark which enables the F to be minimum into a path planning preference table;

optionally, detecting whether the current node is a target position indication mark, and if so, exiting the loop;

optionally, detecting a next initial position or position indicator node around the current node, where the next node includes the initial position or position indicator, and if the next node is not reachable (e.g., cannot penetrate the wall) or is in the path planning preference table, ignoring the node; detecting a next node around the current node, adding the next node into the path planning search table when the next node is not in the path planning search table, recording the current node as a father node of the next node, and calculating an F value of the next node; when the next node is in the path planning search table, calculating whether the F value from the current node to the next node is smaller than the original F value, and if so, recording the current node as a father node of the next node;
