Technical Field

[0001] This application relates to the field of electronic tour guide technology, and in particular to an intelligent tour guide method and related device. Background Technology

[0002] With the accelerating pace of life and work, people's need for quickly obtaining target information is increasing. In situations with vast spaces, numerous targets, and large amounts of information, such as exhibition halls, scenic spots, airport terminals, warehouses, supermarkets, and libraries, both managers and consumers require a mobile device that can move quickly and intelligently to obtain the required information or target.

[0003] In museums, science and technology museums, exhibition halls, trade fairs, and convention centers, exhibitors provide manual explanations and introductions. However, when there are many visitors or a shortage of guides, the service often falls short. Explanation is a repetitive task, and low-cost, practical guided tour robots could reduce the workload of guides and increase visitor interest. However, current guided tour robots suffer from problems such as difficulty in robot positioning, leading to untimely and inaccurate switching of narration content. Summary of the Invention

[0008] Establish a communication connection with the first positioning stake, obtain exhibit information of the target exhibit, and output the exhibit information;

[0009] The second communication message is detected. It is determined whether the second communication message is sent by the second positioning stake. The second positioning stake is a signal transmitting device that is located one position after the first positioning stake in the target guide route.

[0010] If so, stop outputting exhibit information and switch the first channel of the currently connected first positioning stake to the second channel of the second positioning stake.

[0011] In one possible embodiment, the tour guide robot includes an image sensor; outputting exhibit information includes: outputting exhibit information according to a preset explanation mode, the preset explanation mode being used to characterize a user-preset mode for outputting exhibit information in a target language and target manner, the target manner including voice output and / or image output; detecting the user's state when outputting exhibit information by controlling the image sensor; if the user's state is walking, stopping the output of exhibit information, determining the location of the next exhibit according to the tour guide route, and controlling the tour guide robot to move there; if the user's state is standing, continuing to output exhibit information until the output is completed.

[0012] In one possible embodiment, the voice output includes outputting to a wireless headset, which is an audio output device worn by a user and pre-paired with the tour guide robot; outputting exhibit information according to a preset explanation mode, including: after establishing a communication connection with the first positioning post, configuring the tour guide robot's communication channel with a first channel within the signal coverage area of ​​the first positioning post; controlling the wireless headset to configure the first channel based on the pairing status with the wireless headset; after detecting a second communication message, switching the tour guide robot's communication channel to a second channel within the signal coverage area of ​​the second positioning post; and controlling the wireless headset to switch to the second channel.

[0013] In one possible embodiment, after establishing a communication connection with the first positioning stake, the method further includes: acquiring an image of the target exhibit by controlling an image sensor; analyzing whether the target exhibit corresponds to an exhibit identifier based on the exhibit image; if they correspond, querying the exhibit identifier to obtain exhibit information; if they do not correspond, disconnecting the communication link with the first positioning stake and searching for other external communication messages, wherein the other communication messages are communication messages sent by other positioning stakes, and the other positioning stakes are signal transmitting devices other than the first positioning stake; establishing a communication connection with other positioning stakes after receiving other communication requests from other positioning stakes; and obtaining exhibit information of the target exhibit based on the communication connection with other positioning stakes.

[0014] In one possible embodiment, determining the location of the next exhibit after the target exhibit based on the guide route and controlling the guide robot to proceed there includes: retrieving the second channel information of the second positioning post corresponding to the next exhibit; maintaining a communication connection with the first positioning post; and, upon receiving a second communication message, establishing a communication connection with the second positioning post based on the second channel information.

[0015] In one possible embodiment, acquiring and outputting exhibit information of the target exhibit includes: detecting the signal strength between the guide robot and the first positioning stake; pausing the output of exhibit information when the signal strength is less than a preset signal strength; and outputting exhibit information when the signal strength is greater than the preset strength.

[0016] In one possible embodiment, the tour guide robot includes an electronic display screen; before controlling the tour guide robot to move along the target tour guide route, the method further includes: controlling the electronic display screen to output multiple reference tour guide routes, the reference tour guide routes being determined based on the visit value of multiple exhibits and the consistency of exhibit themes, the reference tour guide routes including at least one of the following information: multiple exhibits, tour guide start point location, tour guide end point location; receiving a user's selection operation on the reference tour guide routes, the selection operation including selection and / or custom modification, custom modification referring to the user selecting to visit one or more of the multiple exhibits, and modifying the tour guide start point location and tour guide end point location; determining the route after the selection operation as the target tour guide route.

[0017] Secondly, this application provides an intelligent tour guide device, applied to the controller of a tour guide robot. The intelligent tour guide device includes: a control unit, a receiving unit, a communication unit, a detection unit, and a switching unit. The control unit controls the tour guide robot to move along a target tour route, which is a route passing through multiple exhibits in an exhibition hall. The receiving unit receives a first communication message, which is a message sent by a first positioning post requesting the establishment of a communication connection. The first positioning post is a signal transmitting device installed in the area where the target exhibit is located. The communication unit establishes a communication connection with the first positioning post, obtains exhibit information of the target exhibit, and outputs the exhibit information. The detection unit detects a second communication message and determines whether the second communication message was sent by a second positioning post, which is a signal transmitting device located one position after the first positioning post in the target tour route. The switching unit, if the second communication message is indeed sent by a second positioning post, stops outputting exhibit information and switches the currently connected first channel of the first positioning post to the second channel of the second positioning post.

[0018] Thirdly, embodiments of this application provide an electronic device, including a processor, a memory, a communication interface, and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the processor, and the programs include instructions for performing steps in any method of the first aspect of this application.

The computer program product may be a software installation package.

[0021] As can be seen, through the aforementioned intelligent tour guide method and related devices, the tour guide robot is first controlled to move along the target tour guide route. Then, it receives the first communication message, establishes a communication connection with the first positioning post, obtains and outputs the exhibit information, then detects the second communication message and determines whether it was sent by the second positioning post. Finally, if so, it stops outputting exhibit information and switches the currently connected first channel of the first positioning post to the second channel of the second positioning post. By establishing a stable communication connection with the exhibit positioning post, the accuracy of the tour guide robot's positioning is improved, thereby ensuring that the robot switches the tour guide content in a timely and accurate manner, enhancing the user experience.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0036] The following describes the relevant content, concepts, meanings, technical issues, technical solutions, and beneficial effects involved in the embodiments of this application.

[0037] In museums, science and technology museums, exhibition halls, trade fairs, and convention centers, exhibitors provide manual explanations and introductions. However, when there are many visitors or a shortage of guides, the service often falls short. Explanation is a repetitive task, and low-cost, practical guided tour robots could reduce the workload of guides and increase visitor interest. However, current guided tour robots suffer from problems such as difficulty in robot positioning, leading to untimely and inaccurate switching of narration content.

[0038] To address the aforementioned issues, this application provides an intelligent tour guide explanation method and related device. By establishing a stable communication connection with exhibit positioning posts, the accuracy of the tour guide robot's positioning is improved, thereby ensuring that the robot switches tour guide explanation content in a timely and accurate manner, thus enhancing the user experience.

[0039] First, the method in the embodiments of this application is applied to the controller of the tour guide robot, combined with Figure 1 This application describes an intelligent tour guide method in its embodiments. Figure 1 This is a functional unit composition diagram of a tour guide robot provided in an embodiment of this application. The tour guide robot 100 includes a controller 110, an image sensor 120, and a speaker device 130. The controller 110 is first used to control the tour guide robot to move along the target tour route; secondly, it is used to receive a first communication message; then, it is used to establish a communication connection with a first positioning post; then, it is used to detect a second communication message, determine whether the second communication message was sent by a second positioning post; and finally, if so, it stops outputting exhibit information and switches the first channel of the currently connected first positioning post to the second channel of the second positioning post. The image sensor 120 is used to acquire exhibit images of the target exhibits and user images, so that the controller can analyze whether the exhibit is the target exhibit and analyze the user's movement state (standing while visiting or walking away) based on the exhibit images and user images. The speaker device 130 is used to output voice information. Specifically, the controller 110 includes a wireless communication unit 111 for establishing communication links with the first and second positioning posts.

[0040] The following is combined Figure 2 This application describes an intelligent tour guide method based on an embodiment of the present application. Figure 2 This is a flowchart illustrating an intelligent tour guide explanation method provided in an embodiment of this application, which specifically includes the following steps:

[0041] Step S210: Control the guide robot to move along the target guide route.

[0042] The target guide route is a guide route that passes through multiple exhibits in the exhibition hall; specifically, the exhibition hall can be a museum, exhibition hall, expo, or convention center.

[0043] In one possible example, the tour guide robot includes an electronic display screen; before controlling the tour guide robot to move along the target tour guide route, the method further includes: outputting multiple reference tour guide routes by controlling the electronic display screen, the reference tour guide routes being determined based on the visit value of multiple exhibits and the consistency of exhibit themes, and the reference tour guide routes including at least one of the following information: multiple exhibits, tour guide start point location, and tour guide end point location; receiving user selection operations on the reference tour guide routes, the selection operations including selection and / or custom modification, custom modification referring to the user selecting to visit one or more of the multiple exhibits, and modifying the tour guide start point location and tour guide end point location; and determining the route after the selection operation as the target tour guide route.

[0044] The electronic display screen can be a touch screen, used to receive user selection operations for the reference guide route. The selection operation can be made by the user touching the screen with their finger or by checking a box with a button, and there are no restrictions on this.

[0045] Specifically, please refer to Figure 3 , Figure 3 This is a schematic diagram of a reference tour guide route provided in an embodiment of this application, such as... Figure 3 As shown, the tour route 310 includes passing through exhibits A 320, B 330, C 340, and D 350. The selection bar 321 represents the state after the user's selection; on the one hand, the user can freely select the exhibits they wish to visit, such as... Figure 3 As shown, visitors can customize their tour routes. On the other hand, multiple guided tour routes can be determined based on the viewing value and theme of different exhibits, and these routes can be displayed on the electronic screen of the guide robot.

[0046] Specifically, the implementation details of the user-defined route are explained in detail. First, the route generation logic is described: the user selects two categories of exhibits, "Jade" and "Calligraphy and Painting," on the electronic screen. The system generates the optimal path based on Dijkstra's algorithm, avoiding temporarily closed areas (data synchronized from the exhibition hall management platform). Next, the positioning stake sequence is reconstructed: the original route's preset positioning stake sequence is P1→P2→P3→P4. After the user deletes P3 (the calligraphy and painting exhibit), the controller automatically reconstructs the sequence to P1→P2→P4 and updates the channel switching priority: virtual positioning stakes P2-4 are added in the transition zone from P2 to P4, using a Mesh network relay to ensure signal continuity. Then, real-time route correction is performed. If the user stays at P2 for an extended period (>twice the preset explanation time), the robot prompts: "Skip subsequent exhibits?" After confirmation, a wake-up command is immediately sent to the next target positioning stake (P4), shortening its response delay to 50ms.

[0047] As can be seen in this example, by controlling the electronic display screen to output multiple reference guide routes, receiving the user's selection of a reference guide route, and determining the route after the selection as the target guide route, the system provides users with the freedom to choose guide routes and select exhibits that match their interests, thereby improving the user experience and enhancing the targeted and personalized nature of the intelligent guide.

[0048] In other possible examples, this embodiment combines Figure 3 The reference route shown illustrates how the positioning posts dynamically adjust signal parameters based on exhibit density. First, signal power modeling is performed within the exhibition area. In the ceramics exhibition area (exhibit spacing 1.5 meters), the positioning post power is set to -30dBm (coverage radius 1.2 meters); in the sculpture exhibition area (exhibit spacing 4 meters), the power is set to -15dBm (coverage radius 4 meters). Power parameters are dynamically loaded using a pre-installed exhibition hall topology map on the robot. Second, real-time environmental interference compensation is implemented. When the robot detects a surge in visitor traffic (counted by infrared sensors >50 people / minute), an anti-interference mode is activated: the positioning posts switch to FLRC (Forward Error Correction Coding) modulation mode to improve signal penetration; the channel bandwidth is dynamically increased to 2MHz to avoid signal attenuation caused by multipath effects. Then, seamless cross-exhibition roaming is performed. When the robot moves from the ceramics exhibition area (high frequency, low power) to the sculpture exhibition area (low frequency, high power), the signal attenuation curve is predicted, and a power switching command is sent to the headphones 200ms in advance to ensure that the user's audio latency is less than 100ms (imperceptible to the human ear) when crossing areas.

[0049] Step S220: Receive the first communication message.

[0050] The first communication message is a message sent by the first positioning stake requesting the establishment of a communication connection. The first positioning stake is a signal transmitting device installed in the area where the target exhibit is located. Specifically, the target area is first divided into multiple sub-areas; each sub-area is equipped with positioning stakes, which emit positioning signals indicating the sub-area corresponding to that stake. Specifically, the power of the positioning stakes is adjustable, including 64 power levels. Distance judgment is adjusted by changing the power levels; different power levels result in different signal distances. By setting different power combinations based on the different distances between exhibits, the exhibits can be located. For example, power is reduced when exhibits are densely packed, and increased when exhibits are sparsely packed. Using 433MHz radio frequency modulation methods, such as LoRA, FLRC, and GFSK, compared to Bluetooth, it has stronger penetration and is not obstructed. The communication chip can be Cc12201. The 63 power levels range from -38dBm to -12dBm non-linearly, and after -12dBm, it changes linearly in 4dBm steps. Different power levels result in different signal coverage areas.

[0051] Step S230: Establish a communication connection with the first positioning stake, obtain exhibit information of the target exhibit, and output the exhibit information.

[0052] After establishing a communication connection with the first positioning stake, the exhibit identifier of the target exhibit associated with the first positioning stake is obtained. The exhibit identifier is a unique identifier of the target exhibit and corresponds one-to-one with the target exhibit. The exhibit information is determined based on the exhibit identifier.

[0053] Step S240: Detect the second communication message and determine whether the second communication message was sent by the second positioning stake.

[0054] The second positioning post is a signal transmitter located one position after the first positioning post in the target guide route. If the guide robot receives the second communication message, it may be because the robot has moved into the signal coverage area of ​​the second positioning post, indicating that the robot has left the target exhibit explanation and is preparing to start explaining the next exhibit. At this time, it is necessary to determine whether the second communication message is the second positioning post, which is the one position after the first positioning post indicated by the target guide route.

[0055] Step S250: If yes, stop outputting exhibit information and switch the first channel of the currently connected first positioning stake to the second channel of the second positioning stake.

[0056] If it is the second positioning stake, it confirms that the tour guide robot is moving along the correct target tour guide route and explaining the exhibits in the correct order. If the second communication message is detected, it proves that the tour guide robot has actively left the target exhibit area, indicating that the user is not very interested in the target exhibit or has finished listening to the information about the target exhibit and is preparing to move on to the next exhibit area. At this time, the tour guide robot stops outputting exhibit information.

[0057] As can be seen in this example, the robot first moves along the target tour route, then receives the first communication message, establishes a communication connection with the first positioning post, obtains and outputs the exhibit information, then detects the second communication message and determines whether it was sent by the second positioning post. Finally, if so, it stops outputting exhibit information and switches the first channel of the currently connected first positioning post to the second channel of the second positioning post. By establishing a stable communication connection with the exhibit positioning post, the accuracy of the robot's positioning is improved, thereby ensuring that the robot switches the tour guide content in a timely and accurate manner, enhancing the user experience.

[0058] In one possible example, the tour guide robot includes an image sensor; outputs exhibit information, including: outputting exhibit information according to a preset explanation mode, the preset explanation mode being used to characterize a user-preset pattern for outputting exhibit information in a target language and target manner, the target manner including voice output and / or image output; detecting the user's state while outputting exhibit information by controlling the image sensor; if the user's state is walking, stopping the output of exhibit information, determining the location of the next exhibit according to the tour guide route, and controlling the tour guide robot to move there; if the user's state is standing, continuing to output exhibit information until the output is complete.

[0059] Specifically, the first step is to preset the explanation mode settings. Users select the "Chinese voice + image display" mode in the robot's settings interface, with Chinese as the target language and both voice and image output as the target methods. Next, user status detection is performed. The robot captures the user's posture using a dual-camera system (image sensor). If the user is continuously standing and their gaze is focused on exhibit A, the complete explanation continues. If the user begins to move (e.g., turning towards exhibit B), the robot immediately pauses the explanation and sends a command to the controller: "User status: walking, trigger route switching." Then, adaptive control is applied. If the user is walking, the robot determines the location of the next exhibit B based on the guide route and moves to the area containing exhibit B. If the user is standing, the robot continues to output explanation information for exhibit A until the explanation is complete.

[0060] The target language can be Chinese, English, French, etc., and the target method can be to output exhibit information through voice or to display subtitles and graphic information on an electronic display screen.

[0061] Specifically, while controlling the output of exhibit information, the controller also controls the image sensor to acquire and analyze the user's posture. If the user is in a walking posture, that is, moving their feet and waving their arms, it is determined that the user is not interested in the explanation of this exhibit or has already listened to the part that is interesting. The controller then controls the guide robot to move to the next exhibit area and explain the next exhibit to the user. If the user is standing, it is determined that the user is listening to the output of exhibit information, and the exhibit information is continuously output.

[0062] As can be seen in this example, exhibit information is output according to a preset explanation mode. An image sensor is used to detect the user's state while outputting this information. If the user is walking, the output stops, the next exhibit is located based on the guide's route, and the guide robot moves to that exhibit. If the user is standing, the output continues until all information is displayed. In this way, by detecting different user movement states using an image sensor and automatically switching the explanation content, the user experience is optimized, and the intelligence level of the tour guide's explanations is improved.

[0063] In other possible examples, this embodiment addresses a group tourist scenario, illustrating how a tour guide robot can achieve segmented explanations through multi-locator collaboration. ① Multi-locator network configuration: Three locator stakes (L1, L2, L3) are deployed around a large exhibit (such as the Dunhuang mural restoration area), corresponding to different sections of the mural (sections 1-3). Each stake uses a TDMA (Time Division Multiple Access) mechanism with a time slot interval of 50ms. ② User group identification: The tour guide robot uses UWB (Ultra-Wideband) positioning technology to identify three groups of users (Group1-3) within a 5-meter range. The controller allocates an independent communication channel to each group.

[0064] Group 1 (near paragraph 1): Binds L1 channel (frequency 920MHz);

[0065] Group 2 (near paragraph 2): Binds L2 channel (frequency 922MHz);

[0066] Group3 (Moving): Save the previous explanation and activate it after entering the L3 coverage area.

[0067] ③ Content is pushed out in time slots, and the tour guide robot processes data from multiple channels in a loop within the same time period:

[0068] 0-50ms: Push paragraph 1 explanation to Group 1 via L1;

[0069] 50-100ms: Push paragraph 2 explanation to Group2 via L2;

[0070] 100-150ms: Scan L3 signal and preload paragraph 3 content.

[0071] ④ Conflict resolution strategy: If two groups of users enter the same exhibit area simultaneously (e.g., Group 1 accidentally enters the L2 area), the tour guide robot will initiate conflict detection:

[0072] By identifying the registration ID of Group1 (such as the RFID badge worn by the user) using an image sensor, its communication link is forcibly switched back to L1;

[0073] If the signal overlap continues for more than 5 seconds, a voice prompt will be triggered: "You have deviated from the current explanation area. Please return or select a new route."

[0074] In one possible example, the voice output includes outputting to a wireless headset, which is an audio output device worn by the user and pre-paired with the tour guide robot; outputting exhibit information according to a preset explanation mode, including: after establishing a communication connection with the first positioning post, configuring the tour guide robot's communication channel with a first channel within the signal coverage area of ​​the first positioning post; controlling the wireless headset to configure the first channel based on the pairing status with the wireless headset; after detecting a second communication message, switching the tour guide robot's communication channel to a second channel within the signal coverage area of ​​the second positioning post; and controlling the wireless headset to switch to the second channel.

[0075] Specifically, the process begins with wireless headset pairing and channel configuration. The user's Bluetooth headset is pre-paired with the tour guide robot. Once the robot establishes a communication connection with the first positioning post, its communication channel is configured with the first channel (frequency 868MHz) within the signal coverage area of ​​the first positioning post, and the wireless headset switches to this first channel. Then, channel switching occurs. When the robot detects a second communication message (from the second positioning post), it switches its communication channel to the second channel (frequency 868.5MHz) within the signal coverage area of ​​the second positioning post, and the wireless headset switches to this second channel as well. The headset completes the channel switching within 20ms, maintaining audio continuity and preventing audio dropouts through buffering technology.

[0076] The first positioning post is equipped with a dedicated first channel, and the second positioning post is equipped with a dedicated second channel. The tour guide robot is used as a signal switching relay device. When the tour guide robot connects to the first channel, it controls the wireless headphones to switch to the first channel, outputting the explanation information of the exhibits corresponding to the first positioning post in a high-quality and efficient manner. Similarly, when the tour guide robot connects to the second channel, it controls the wireless headphones to switch to the second channel.

[0077] In this example, a communication connection is established between the tour guide robot and the first positioning stake. The first channel of the signal coverage area of ​​the first positioning stake is configured for the tour guide robot's communication channel. Based on the pairing status with the wireless headset, the wireless headset is controlled to configure the first channel. Upon detecting a second communication message, the wireless headset is controlled to switch to the second channel. This improves the success rate of wireless headset channel switching, avoids switching errors and failures when switching communication channels, enhances the tour guide robot's narration effect and quality, and further improves the user experience.

[0078] In one possible example, the tour guide robot includes an image sensor; after establishing a communication connection with the first positioning stake, the method further includes: acquiring an image of the target exhibit by controlling the image sensor; analyzing whether the target exhibit corresponds to an exhibit identifier based on the exhibit image; if they correspond, querying the exhibit identifier to obtain exhibit information; if they do not correspond, disconnecting the communication link with the first positioning stake and searching for other external communication messages, which are communication messages sent by other positioning stakes, which are signal transmitting devices other than the first positioning stake; establishing a communication connection with other positioning stakes after receiving other communication requests from other positioning stakes; and obtaining exhibit information of the target exhibit based on the communication connection with other positioning stakes.

[0079] Please refer to Figure 4 , Figure 4 This is a schematic diagram illustrating an application scenario for tour guide explanation provided in an embodiment of this application, such as... Figure 4 As shown, the first positioning post 410 and its signal coverage area 411, and the second positioning post 430 and its signal coverage area 431. When the tour guide robot 420 passes the first positioning post 410 and the second positioning post 430, it will receive two communication messages at the same time. If it is not further verified at this time, there may be errors in the explanation, resulting in a decline in user experience. Therefore, the controller controls the image sensor to obtain the exhibit image of the target exhibit, and further verifies whether a communication connection has been established with the corresponding first positioning post 410 through the exhibit image. If it is, the exhibit information is output; if not, a communication connection is established with the second positioning post 430 according to the other communication message.

[0080] Specifically, please refer to Figure 5 , Figure 5 This application provides a flowchart of a specific process for controlling a tour guide robot, which includes the following steps:

[0081] S510, Acquisition and Analysis of Exhibit Images.

[0082] After establishing a communication connection with the first positioning stake, the robot acquires an image of exhibit A through an image sensor and analyzes the exhibit's features (such as patterns and shapes) in the image.

[0083] S520. Exhibit identification matching: If the image features match the exhibit identification, query the exhibit identification to obtain the explanation information of exhibit A; if they do not match, disconnect the communication link with the first positioning stake and search for other external communication messages.

[0084] S530. Perform exception handling. If a communication request is detected from another positioning stake, the robot establishes a communication connection with it and obtains the explanation information of exhibit B.

[0085] As can be seen in this example, the system acquires images of the target exhibit using an image sensor. Based on these images, it analyzes whether the target exhibit corresponds to its identifier. If they match, the system queries the identifier to obtain the exhibit information. If they do not match, the communication link with the first positioning stake is disconnected, and the system searches for other external communication messages. Upon receiving other communication requests from other positioning stakes, a communication connection is established with those stakes. Furthermore, based on these communication connections, the system obtains the exhibit information of the target exhibit. This avoids errors in receiving exhibit information due to connection errors, which could lead to incorrect explanations and thus optimizes the intelligence level of the tour guide robot.

[0086] In one possible example, determining the location of the next exhibit after the target exhibit based on the guide route and controlling the guide robot to proceed there includes: retrieving the second channel information of the second positioning post corresponding to the next exhibit; maintaining a communication connection with the first positioning post; and, upon receiving a second communication message, establishing a communication connection with the second positioning post based on the second channel information.

[0087] Among them, maintaining a stable connection with the first positioning stake when not connected to the next positioning stake is a transitional channel switching method, which is beneficial for quickly and smoothly switching communication links.

[0088] Specifically, the next exhibit is first located. The guide robot determines the position of exhibit B according to the guide route and retrieves the second channel information (frequency 868.5MHz) of the second positioning post corresponding to exhibit B. Then, a smooth switch occurs. When not connected to the second positioning post, the guide robot maintains communication with the first positioning post. Upon receiving the second communication message, it establishes communication with the second positioning post based on the second channel information, ensuring a smooth channel switch.

[0089] Specifically, wireless headphones can be Bluetooth headphones. Depending on the Bluetooth standard, the number of channels on a Bluetooth headset will vary. For example, Classic Bluetooth (BR / EDR) typically uses 79 frequency-hopping channels, each with a bandwidth of 1MHz; while Bluetooth Low Energy (BLE) uses 40 channels, 37 of which are general-purpose channels for connection and communication, and the other 3 are broadcast channels for device discovery and data broadcasting. The transitional channel switching function of Bluetooth headsets relies on the implementation of the Bluetooth protocol stack. The Bluetooth protocol stack is the foundation for communication between Bluetooth headsets and Bluetooth devices. Device discovery and pairing: Before transitional channel switching, Bluetooth headsets need to discover and pair with the target device. This process typically involves steps such as device search, authentication, and key exchange.

[0090] As can be seen in this example, by retrieving the second channel information of the second positioning post corresponding to the next exhibit; maintaining the communication connection with the first positioning post; and, upon receiving the second communication message, establishing a communication connection with the second positioning post based on the second channel information, a smooth and seamless channel switching between wireless devices is achieved, providing users with a convenient and smooth user experience.

[0091] In other possible examples, this embodiment uses a museum scenario as an example to explain the implementation of dynamically switching the narration content based on signal strength, combined with... Figure 2 and Figure 4 The illustrated process and application scenarios explain in detail how the tour guide robot dynamically controls the start and stop of the narration content based on the signal strength of the positioning stakes. Please refer to [link / reference needed]. Figure 6 , Figure 6 This is another specific flowchart of controlling a tour guide robot provided in this application embodiment, including the following steps:

[0092] S610, Initial Route Planning.

[0093] In this system, users select the "Bronze Ware Theme Route" via the touchscreen of the guided robot. This route includes exhibit A (Shang Dynasty Ding), exhibit B (Western Zhou Dynasty Gui), and exhibit C (Warring States Period Hu). The robot generates the target guided route based on the selection and plans the movement path.

[0094] S620, Signal Connection and Information Acquisition.

[0095] When the tour guide robot approaches exhibit A, it enters the signal coverage area of ​​the first positioning stake (installed 1 meter to the side of exhibit A). The first positioning stake uses the LoRa communication protocol, with a transmission power set to -20dBm (coverage radius of 3 meters). The tour guide robot detects a signal strength of -66dBm (higher than the preset threshold of -70dBm), then establishes a communication connection with the first positioning stake, obtains the identification code "A-001" for exhibit A, and retrieves the associated audio narration file (3 minutes in length) and high-definition 3D model data from the cloud database.

[0096] S630, multimodal information output.

[0097] The robot guide plays a voice narration through its built-in speaker: "The Shang Dynasty ding is a sacrificial ritual vessel, 68 centimeters high, decorated with taotie patterns..." Simultaneously, an electronic display shows a 3D rotating model of the ding. The user's Bluetooth headset (already paired with the robot) receives the audio stream through the dedicated channel (868MHz frequency) of the first positioning post, avoiding interference from public Wi-Fi channels.

[0098] S640, User Status Detection and Adaptive Control.

[0099] Among them, the tour guide robot captures the user's posture through a binocular camera. Figure 1 (Image sensor in the middle). If the robot detects that the user is standing still and focused on exhibit A, it continues playing the full narration; if the user starts to move (such as turning around and walking towards exhibit B), the tour guide robot immediately pauses the narration and sends a command to the controller: "User status: walking, trigger route switching".

[0100] S650, smooth channel switching.

[0101] When the tour guide robot moves to the boundary area between exhibit A and exhibit B, it simultaneously receives signals from the first positioning stake (signal strength attenuated to -76dBm) and the second positioning stake (signal strength -68dBm). The controller retrieves the channel parameters (frequency 868.6MHz) of the next positioning stake in the target route and sends a channel switching command to the Bluetooth headset. The headset completes the channel switching within 20ms, maintaining audio continuity and avoiding dropouts during this period through buffering technology.

[0102] S660, Exception Handling.

[0103] If the signal of the second positioning stake is abnormal (such as power fluctuation or hardware failure), the tour guide robot will activate the backup plan: using SLAM (Simultaneous Localization and Mapping) technology combined with the pre-stored exhibition hall map, it will autonomously navigate to the coordinates of exhibit B; it will call the image sensor to identify the features of exhibit B and directly retrieve the explanation content from the local database; and it will upload the fault log to the cloud operation and maintenance system via the 4G network.

[0104] In one possible example, acquiring and outputting exhibit information for the target exhibit includes: detecting the signal strength between the guide robot and the first positioning stake; pausing the output of exhibit information when the signal strength is less than a preset signal strength; and outputting exhibit information when the signal strength is greater than the preset signal strength.

[0105] Specifically, the signal strength between the guide robot and the first positioning stake can be assessed by evaluating the receiver sensitivity. Receiver sensitivity is a parameter that evaluates the ability of a wireless device to maintain normal operation in a weak signal environment, and is usually expressed in dBm (decibels per milliwatt). Common receiver sensitivity standards are typically around -70dBm. That is, when the signal strength reaches or exceeds -70dBm, the wireless device can receive and process the signal normally, thereby maintaining a stable connection.

[0106] For example, signal strength detection is performed first, with the tour guide robot checking the signal strength relative to the first positioning stake. If the signal strength is -65dBm (higher than the preset threshold of -70dBm), the guide robot outputs explanation information for exhibit A. Then, a weak signal processing operation is performed. If the signal strength attenuates to -75dBm (lower than the preset threshold), the tour guide robot pauses the output of explanation information and attempts to reconnect or switch to an alternate channel.

[0107] As can be seen, this example detects the signal strength between the tour guide robot and the first positioning stake. When the signal strength is less than a preset signal strength, the output of exhibit information is paused; when the signal strength is greater than the preset signal strength, the exhibit information is output. This avoids the tour guide robot forcibly maintaining a connection with the first positioning stake when the signal is weak, ensuring a connection is established when the signal is strong, improving the quality of communication data transmission, and optimizing the user's visitor experience.

[0108] The above primarily describes the solutions of the embodiments of this application from the perspective of the method execution process. It is understood that, in order to achieve the above functions, mobile electronic devices include corresponding hardware structures and / or software modules for executing each function. Those skilled in the art should readily recognize that, in conjunction with the units and algorithm steps of the various examples described in the embodiments provided herein, this application can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed by hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.

[0109] This application embodiment can divide the electronic device into functional units according to the above method example. For example, each function can be divided into a separate functional unit, or two or more functions can be integrated into one processing unit. The integrated unit can be implemented in hardware or as a software functional unit.

Figure 7 , Figure 7 This is a functional unit block diagram of an intelligent tour guide device provided in an embodiment of this application. The intelligent tour guide device 700 is applied to, for example... Figure 1The controller 110 of the guide robot 100 shown includes: a control unit 710, a receiving unit 720, a communication unit 730, a detection unit 740, and a switching unit 750. The control unit 710 controls the guide robot to move along a target guide route, which is a route passing through multiple exhibits in the exhibition hall. The receiving unit 720 receives a first communication message, which is a message sent by a first positioning post requesting the establishment of a communication connection. The first positioning post is a signal transmitting device installed in the area where the target exhibit is located. The communication unit 730 establishes a communication connection with the first positioning post, acquires exhibit information of the target exhibit, and outputs the exhibit information. The detection unit 740 detects a second communication message and determines whether the second communication message was sent by a second positioning post, which is a signal transmitting device located one position after the first positioning post in the target guide route. The switching unit 750, if the second communication message is indeed sent by a second positioning post, stops outputting exhibit information and switches the currently connected first channel of the first positioning post to the second channel of the second positioning post.

[0111] In one possible example, the tour guide robot includes an image sensor; the communication unit 730 is specifically used to: output exhibit information according to a preset explanation mode, the preset explanation mode being used to characterize a user-preset mode for outputting exhibit information in a target language and target manner, the target manner including voice output and / or image output; detect the user's state when outputting exhibit information by controlling the image sensor; if the user's state is walking, stop outputting exhibit information, determine the location of the next exhibit according to the tour guide route, and control the tour guide robot to move there; if the user's state is standing, continue outputting exhibit information until the output is completed.

[0112] In one possible example, the voice output includes output to a wireless headset, which is an audio output device worn by the user and pre-paired with the tour guide robot; outputting exhibit information according to a preset explanation mode; and the communication unit 730 is specifically used to: after establishing a communication connection with the first positioning post, configure the communication channel of the tour guide robot to the first channel of the signal coverage area of ​​the first positioning post; control the wireless headset to configure the first channel based on the pairing status with the wireless headset; after detecting a second communication message, switch the communication channel of the tour guide robot to the second channel of the signal coverage area of ​​the second positioning post; and control the wireless headset to switch to the second channel.

[0114] In one possible example, the location of the next exhibit after the target exhibit is determined according to the guide route, and the guide robot is controlled to go there. The communication unit 730 is specifically used to: retrieve the second channel information of the second positioning post corresponding to the next exhibit; maintain the communication connection with the first positioning post; and, after receiving the second communication message, establish a communication connection with the second positioning post based on the second channel information.

[0115] In one possible example, the receiving unit 720 acquires and outputs exhibit information of the target exhibit. Specifically, it is used to: detect the signal strength between the guide robot and the first positioning stake; pause the output of exhibit information when the signal strength is less than the preset signal strength; and output exhibit information when the signal strength is greater than the preset strength.

[0116] In one possible example, the tour guide robot includes an electronic display screen; before controlling the tour guide robot to move along the target tour guide route, the control unit 710 is specifically configured to: output multiple reference tour guide routes through the electronic display screen, the reference tour guide routes being determined based on the visit value of multiple exhibits and the consistency of exhibit themes, and the reference tour guide routes including at least one of the following information: multiple exhibits, tour guide start point location, and tour guide end point location; receive user selection operations for reference tour guide routes, the selection operations including selection and / or custom modification, custom modification referring to the user selecting to visit one or more of the multiple exhibits, and modifying the tour guide start point location and tour guide end point location; and determine the route after the selection operation as the target tour guide route.
