Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
The invention provides a method, equipment and a storage medium for dynamically selecting network connection points, aiming at meeting the requirement that a robot can be connected with a server only by local network signal intensity in a robot operation area and saving network deployment cost; by the method of enabling the robot to dynamically collect, store and share the network communication quality data in the working area, the robot can actively go to a communicable area and obtain communication with the server when needing to communicate with the server, so that tasks, task synchronization information and the like can be obtained from the server; and then greatly reduce the requirement of the robot on the network coverage degree and reduce the deployment cost. For example, if the robot uses a 3G networking mode, a 4G networking mode, etc., and the robot operation area only needs to have local network signal strength meeting the requirement of "the robot connects to the server", network deployment can be almost omitted, so that the network deployment cost approaches zero.
As shown in fig. 1, fig. 1 is a flowchart illustrating an embodiment of a method for dynamically selecting a network connection point according to the present invention; the method for dynamically selecting a network connection point according to the present invention may be implemented as steps S10-S40 as follows:
step S10, the robot acquires a network quality map; wherein the network quality map comprises: relation information between a position point reachable by the robot and the network communication quality;
the robot described in the embodiment of the invention, which performs the operation steps described in the embodiment of fig. 1, needs to be movable first and has the ability to reach the position that the robot needs to reach subsequently. If a robot navigates for a SLAM (Simultaneous Localization and Mapping), it is usually indicated that SLAM Mapping has been completed and the SLAM robot can move using the map.
The network communication quality described in the embodiments of the present invention may be understood as: the feasibility that the robot can be in interactive connection with the server can be achieved through any form of network tests such as network ping, accessing a server fixed probe interface, sending test data to the server and observing response time, and therefore whether any point which can be reached by the robot can be communicated with the server or not is comprehensively evaluated. The position points reachable by the robot and the set of network qualities of communication between the robot corresponding to the position points and the server constitute the network quality map.
Wherein the position points that the robot can reach are: the robot is in one of the areas which can communicate with the server and is corresponding to the area coordinates in the whole working area, and the position points can be mutually covered. That is, the reachable location point is actually an area, i.e. an area based on the coordinate representation of the robot within the working area. For example, in a three-dimensional environment, the coordinates of the robot can be uniquely confirmed (x, y, z) under the condition that the influence of the three-dimensional angle of the robot on the network is ignored, and r represents the radius; x, y, z, r represent a spherical space centered around the coordinate (x, y, z) and having a radius r around the coordinate, and this space is a reachable position point of the robot. Where the positions reachable by the robot can overlap each other, the spherical spaces as described in the above example can intersect each other.
Step S20, when the robot needs to connect to the network, according to the network quality chart, selecting a communicable network communication point and reaching the selected network communication point;
since the robot described in the embodiments of the present invention does not need to perform real-time data interaction with the server, the robot does not always need a network connection. For example, when the robot can work off-line, data interaction with the server is not needed, and therefore network connection is not needed. When the robot needs to get the task to be executed issued by the server online or needs to go online for data synchronization, and the robot needs to report the execution result of the task, network connection is needed.
When the robot needs to be connected with a network, a proper network communication point is selected according to the network quality diagram, the state information of the robot and the external state information corresponding to the environment where the robot is located, and the selected network communication point is reached. The state information of the robot itself includes but is not limited to: the current position of the robot, the distance between the current position of the robot and all communication points, the electric quantity information of the robot and the like; the external state information corresponding to the environment where the robot is located includes but is not limited to: the network communication quality of the communication point, the running condition information of the robot, the probability of possible obstacles on the advancing route of the robot, the local congestion probability of the robot, whether the gradient of the advancing route of the robot exceeds the operable gradient range of the robot, and the like; by comprehensively considering the above information, the robot selects one communicable network communication point, and according to the selected network communication point, the robot travels to the selected communicable network communication point according to the corresponding route. In a specific application scenario, the closest network communication point may be selected, or any one of the network communication points may be randomly selected.
Step S30, at the selected network communication point, the robot tries to perform communication connection with the server and judges whether the communication connection with the server is successful;
and step S40, according to the judgment result of whether the communication connection with the server is successful, the robot executes corresponding operation.
When the robot reaches the selected network communication point, the robot attempts a communication connection with the server and judges whether the current communication connection is successful. If the communication connection between the robot and the server is successful, performing data interaction operation with the server; if the communication connection between the robot and the server is unsuccessful, the network communication point is not available, or the server is temporarily in trouble or the server is temporarily unavailable, or the communication module of the robot fails, at this time, the robot selects another network communication point to try to perform communication connection with the server again according to the network quality map.
Further, in an embodiment, the robot selects another network communication point to try to make a communication connection with the server again according to the network quality map, which may be implemented as follows:
the robot selects a preset number of other network communication points according to the network quality graph, and tries to perform communication connection with the server one by one at the selected preset number of network communication points;
if the communication connection with the server can be successful in the selected preset number of network communication points, performing data interaction operation with the server;
and if the communication connection with the server is not successful in the selected preset number of network communication points, the robot sends alarm information to remind maintenance personnel to carry out maintenance operation.
In the embodiment of the invention, when the robot goes to other network communication points to try to carry out communication connection with the server, the server can be on-line again in the period of time due to the fact that time is needed by multiple times of trying, so that the communication is successful; persistent communication failures are also possible. For example, when the robot subsequently and continuously goes to another 3 network communication points to try to perform communication connection with the server, but the continuous communication fails, at this time, the robot may send alarm information to search for and remind maintenance personnel to perform maintenance.
In addition, in one embodiment of the present invention, there are two main ways for the robot to obtain the network quality map: one is that the robot moves in the working area, and collects the relation information between the position point that the robot can reach and the network communication quality, and forms the network quality graph; alternatively, the robot receives a network quality map shared by other robots already in motion within the same work area.
For the network quality graph described in the embodiment of the present invention, when the robot itself collects and acquires information during movement, that is, when the robot moves in a working area, relationship information between a position point reachable by the robot and network communication quality is collected to form the network quality graph, which may be implemented as follows:
the robot moves in a working area, and the feasibility that the robot can be in interactive connection with a server is identified while the robot moves, so that the corresponding network communication quality is obtained;
obtaining a corresponding network quality graph according to the relation information between the position points which can be reached by the robot and the network communication quality;
further, in one embodiment, the robot collects, saves and shares network communication quality information associated with the network quality map in real time while moving within the work area;
and if the robot collects network environment change information containing the change of the network communication quality information in the working area, updating the network communication quality map according to the network environment change information, and sharing the updated network communication quality map to other robots moving in the same working area.
Since the network environment in the working area where the robot operates is not constant but dynamically changing, the network communication quality map collected and/or shared by the robot is naturally also dynamically changing, i.e. the network communication quality map is updated as the network communication quality changes. The robot can continuously collect, store and share the network communication quality diagram at any time, so that the adaptability of the network quality diagram to the actual network environment is improved, and the working efficiency of the robot is improved.
Further, in one embodiment, when the robot moves in the working area, the network communication quality information associated with the network quality map is collected in real time, and meanwhile, the network signal strength information between different network communication points at the moment of collecting the network quality information is obtained, and the signal strength difference information between each network communication point is recorded, so that the robot takes the signal strength difference information as one of the comparison conditions when selecting the corresponding network communication point.
In addition, the robot has the following capabilities: the ability to update signal strength information for the same network communication point. When the robot collects the network communication quality information in the working area in real time, the signal strength information between the network communication points is also recorded; aiming at the same network communication point, when the robot finds that the signal intensity of a certain network communication point is inconsistent with the signal intensity information recorded by the network communication point at different moments, the robot can update the signal intensity information of the network communication point, so that other robots can share the information, and the probability of selecting the network communication point is changed when network communication connection with a service is needed.
The invention discloses a method for dynamically selecting network connection points.A robot acquires a network quality map; wherein the network quality map comprises: relation information between a position point reachable by the robot and the network communication quality; when the robot needs to be connected with a network, selecting a communicable network communication point according to the network quality graph and arriving at the selected network communication point; at the selected network communication point, the robot tries to perform communication connection with the server and judges whether the communication connection with the server is successful; according to the judgment result of whether the communication connection with the server is successful, the robot executes corresponding operation; the purpose that the robot can be connected with the server only through local network signal intensity in the robot operation area is achieved, and network deployment cost is saved.
