The present invention can also be implemented or applied through other different specific implementation modes, and various modifications or changes can be made to the details in this specification based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, in the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

It should be noted that the diagrams provided in the following embodiments are only schematically illustrating the basic ideas of the present invention, and only the components related to the present invention are shown in the diagrams rather than the number, shape and shape of the components in actual implementation. Dimensional drawing, the type, quantity and proportion of each component can be changed arbitrarily during actual implementation, and the component layout type may also be more complicated.

Embodiment one

This embodiment provides an intelligent explanation device for indoor scenic spots, the explanation device includes:

The data storage module stores an explanation matching file and an explanation file, and the explanation matching file has information on each "explaining position" and information on each explaining point corresponding to each explaining position;

The "teaching position" judging module is used to determine whether the explaining device enters the "teaching position" by comparing the position information broadcast by the iBeacon base station with the information of the "teaching position" in the explaining matching file;

The explaining point judging module is used to obtain the direction that the explaining device is facing after judging that the explaining device enters the "explaining position", and then compare the direction information with the information of the "explaining position" in the explaining matching file to judge the current explaining device Whether there are any necessary explanation points in the direction you are facing;

The playback module is used to play the explanation file corresponding to the explanation point through the explanation software when it is judged that there is an explanation point in the direction facing the explanation device.

In this embodiment, the direction that the present teaching device is facing is obtained by a geomagnetic sensor.

The geomagnetic sensor is the core component of the present invention.

A geomagnetic sensor, also called a digital compass, is a method of using the geomagnetic field to determine the North Pole. The compass function on the intelligent explanation device is to use the geomagnetic field and the geomagnetic sensor built into the mobile phone to realize the positioning of the geographical direction. Although GPS has a wide range of applications in navigation and positioning, its signal is often affected by the surrounding environment, resulting in a greatly reduced accuracy. Geomagnetic sensors can make up for this defect. Even if GPS information is lost, the system can still work normally. In this embodiment, an angle range is set for each direction of the "explaining position", and the direction is determined by determining the range it falls into through the data of the geomagnetic sensor. In the preferred embodiment of the present invention, the angle range is set to 30 degrees, for example, when the geomagnetic sensor data falls within [345-15] degrees, it is judged as the direction "North".

The working method of iBeacon is to send its own unique device ID to the surroundings by using the Bluetooth Low Energy (BLE) communication protocol. The iBeacon protocol data is mainly composed of four types of data, namely UUID (Universal Unique Identifier), Major, Minor, and Tx Power. Major and Minor are set by the operator themselves, and both are 16-bit identifiers. In the best example of the present invention, Major is set as the scenic spot ID, and Minor is set as the explanation position ID. The iBeacon receiving device calculates the real-time distance from the iBeacon base station through the Tx Power field and the current BLE signal strength.

In the present invention, in order to realize voice explanation by using an intelligent explanation device, the key information required includes: scenic spot ID, language ID, and explanation location ID. These three ID numbers all occupy 2 bytes (8 bits/byte) in the program. In the present invention, the three kinds of ID numbers play the functions of explaining file search, position matching, direction matching and the like. The specific usage of the ID number is shown in Figure 5 and 6.

In this embodiment, information and explanation files of each explanation point corresponding to each explanation position in the scenic spot are stored in the explanation matching file. The teaching point information of each teaching position is saved in the format of "Teaching Position ID + Angle", arranged in sequence according to the serial number, the serial number is the ID number of the teaching position, and the angle is the angle range of the teaching point at the teaching position. Explain that the location ID number is fixed at 0xFFFF (hexadecimal), which is the specific iBeacon base station address at the entrance of the scenic spot. Specifically, a specific iBeacon is set at the entrance of the scenic spot, and its Minor value is fixed to 0xFFFF. When the interpretation device detects this value, it means that it is about to enter the scenic spot, and then obtain the corresponding Major, which is the ID number of the current scenic spot. , so as to download the corresponding file to the smart device. After entering the scenic spot, the Major, that is, the scenic spot ID value is fixed, and the Minor value can be set to different values according to different explanation positions. The value of location ID is fixed at the entrance of the scenic spot, which is a sign to enter the scenic spot.

The explanation file can be in the form of audio or video, and the explanation file is stored in the intelligent explanation device in the form of a three-level directory. The first-level directory is the scenic spot ID number, the second-level directory is the language ID number, and the third-level directory is the explanation location ID number. The explanation files in the folder are saved according to the file name of "interpretation position ID + angle".

Before normal operation, the entire system needs to be initialized and configured, and the explanation matching files corresponding to the scenic spots should be produced. The initial configuration of the system is shown in flow chart 4. The initial configuration of the system is formed by the staff visiting the scenic spot once along the actual tour route when there is no ready-made explanation matching file. In the initial configuration, the staff accurately records the installation location of the iBeacon base station according to the needs of tourists actually visiting each explanation point in the tour route, that is, determines the specific location of each "interpretation location" in the scenic spot. At the same time, each location is assigned a explaining location ID number, and after the explaining location ID number is written into the corresponding iBeacon base station, the iBeacon base station is installed on the corresponding "teaching location". Furthermore, the staff uses the geomagnetic sensor of the intelligent interpretation equipment to obtain the precise angle corresponding to each explanation point on the current "interpretation position". In order to improve the success rate of the direction matching of the intelligent explanation equipment in the navigation stage, the staff needs to convert the precise angle into an angle matching range according to a certain matching range. For example, if the accurate measurement angle is 10 degrees, the angle range converted according to the range of plus or minus 30 degrees is 340 degrees to 40 degrees. After the initialization, the staff will write all the location matching information into the file to form the explanation matching file corresponding to the scenic spot.

In this embodiment, the intelligent explanation device includes a Bluetooth receiving module, a geomagnetic sensor module, and a data storage module. The Bluetooth receiving module is used to receive the location information sent by the iBeacon base station to determine the current "interpretation position"; the geomagnetic sensor module is used to determine the current direction of the intelligent explanation device; the data storage module is used to store multilingual explanation files and explanation matching files Wait.

It should be noted that the intelligent interpretation equipment here is a mobile intelligent terminal such as a smartphone or a tablet computer, or it can also be provided by a scenic spot. The intelligent explanation equipment stores explanation matching files, explanation files, etc. in advance, or the explanation matching files, explanation files, and playback software are downloaded and installed by tourists in advance.

The tourist chooses the language of explanation according to the prompt of the explanation software, and the explanation software saves the selected language ID number. The intelligent explanation device receives the specific iBeacon base station information at the entrance of the scenic spot through the Bluetooth receiving module, and obtains the explanation location ID. Judging whether the current explanation position ID number is 0xFFFF (hexadecimal), if so, save the scenic spot ID number and the language ID number and send them to the central server. The initialization and configuration of the intelligent interpretation equipment is completed, and it enters the tour mode.

After entering the tour stage, the smartphone receives the low-power Bluetooth IBEACON protocol signal to find and play the corresponding scenic spot explanation file.

During the tour, the intelligent explanation device side explains the matching synchronization method as shown in Figure 6. Specifically include the following steps:

Step 1. Explain that the software enters the tour mode. When the explaining software receives the broadcast data frame of the iBeacon protocol through the Bluetooth receiving module, it compares it with the previously received iBeacon data to determine whether it has received new iBeacon data, that is, to determine whether the visitor has entered a new explaining position.

Step 2. If a new signal is received, the Major and Minor data are extracted from the broadcast data frame, corresponding to the ID number of the scenic spot and the ID number of the explanation location, respectively.

Step 3. If the scenic spot ID number is different from the previously stored scenic spot ID number, the data frame is discarded.

Step 4. If the ID number of the explanation location is successfully matched, it is judged whether the tourist stays in the direction he is facing for more than 3 seconds.

Step 5. If it exceeds 3 seconds, activate the geomagnetic sensor of the intelligent interpretation device.

Step 6. The specific operation after enabling the geomagnetic sensor is shown in Figure 7. Read the geomagnetic sensor data to obtain the precise angle of the direction that the intelligent interpretation device is facing at the interpretation position.

Step 7. Use the ID number of the scenic spot and the language ID number as the matching path, and use the exact angle as the matching condition to match the explaining point of the explaining position ID within the angle range within which the exact angle falls.

Step 8. If the matching is successful, it means that there is an explanation point in the direction here, and the "explanation location ID + angle" in the explanation matching file is used as the explanation file name for local search.

Step 9. If the corresponding explanation file is found, play the corresponding explanation file, save the current location information, and perform a new round of explanation judgment.

In addition, the explanation software works like an ordinary multimedia player during the tour. If tourists are not interested in a certain attraction, they can pause the currently playing file and continue to visit the next attraction; if they are interested in a certain attraction, they can manually Play the tutorial file repeatedly.

Corresponding to the above-mentioned intelligent explanation equipment for indoor scenic spots, this embodiment also provides an explanation method for the intelligent explanation equipment for indoor scenic spots. The explanation equipment stores explanation matching files, explanation software and explanation files. The explanation matching The file has the information of each "teaching position" and the information of each explaining point corresponding to each explaining position;

The explaining equipment receives the position information broadcast by each iBeacon base station, and judges whether the explaining equipment enters the "explaining position" by comparing the position information broadcast by the iBeacon base station with the information of the "explaining position" in the explaining matching file;

When the explaining device enters a "guiding position", it obtains the direction the current explaining device is facing, and then compares the direction information with the information of the "guiding position" in the explaining matching file to determine whether there is a needed explanation points;

When there is an explanation point in the direction facing the explanation device, the explanation file corresponding to the explanation point is played through the explanation software.

When the explaining software receives the broadcast data frame of the iBeacon protocol through the Bluetooth receiving module, it compares it with the previously received iBeacon data to determine whether it has received new iBeacon data, that is, to determine whether the visitor has entered a new explaining position.

Step 2. If a new signal is received, the Major and Minor data are extracted from the broadcast data frame, corresponding to the ID number of the scenic spot and the ID number of the explanation location, respectively.

Step 3. If the scenic spot ID number is different from the previously stored scenic spot ID number, the data frame is discarded.

Step 4. If the ID number of the explanation location is successfully matched, it is judged whether the tourist stays in the direction he is facing for more than 3 seconds.

Step 5. If it exceeds 3 seconds, activate the geomagnetic sensor of the intelligent interpretation device.

Step 6. The specific operation after enabling the geomagnetic sensor is shown in Figure 7. Read the geomagnetic sensor data to obtain the precise angle of the direction that the intelligent interpretation device is facing at the interpretation position.

Step 7. Use the ID number of the scenic spot and the language ID number as the matching path, and use the exact angle as the matching condition to match the explaining point of the explaining position ID within the angle range within which the exact angle falls.

Step 8. If the matching is successful, it means that there is an explanation point in the direction here, and the "explanation location ID + angle" in the explanation matching file is used as the explanation file name for local search.

Step 9. If the corresponding explanation file is found, play the corresponding explanation file, save the current location information, and perform a new round of explanation judgment.

In addition, the explanation software works like an ordinary multimedia player during the tour. If tourists are not interested in a certain attraction, they can pause the currently playing file and continue to visit the next attraction; if they are interested in a certain attraction, they can manually Play the tutorial file repeatedly.

The overall indoor iBeacon base station layout of an intelligent navigation system for indoor scenic spots is shown in Figure 2. Figure 1 shows the arrangement in the existing scheme, that is, each scenic spot is correspondingly installed with an iBeacon base station, and the intelligent interpretation device judges the current explanation point through the Minor value sent by each iBeacon. However, such an arrangement requires a large number of iBeacon base stations, which consumes a lot of resources and costs a lot; however, the present invention optimizes the arrangement, as shown in FIG. 2 . The iBeacon base stations are arranged according to the needs of the tour route, which greatly reduces the number of iBeacon, saves resources, reduces costs, and makes the system green and environmentally friendly.

In a preferred embodiment of the present invention, the intelligent interpretation device is a smart phone or tablet carried by tourists. The central server is deployed at the entrance of the scenic spot. The intelligent explaining equipment first connects to the central server through the WIFI wireless access module to download and install the explaining software. After the installation of the explanation software is completed, the tourists will set the language information used for the explanation, and the explanation software will download the explanation file corresponding to the language of the scenic spot from the central server. In the tour stage, the intelligent interpretation equipment receives the broadcast location information of each iBeacon base station, and determines the "interpretation location". Finally, through the geomagnetic sensor of the intelligent interpretation device itself, the direction that the current intelligent interpretation device is facing is obtained, and the multilingual explanation of the explanation points is realized by searching for explanation matching files.

Further, the intelligent explanation equipment includes:

WIFI wireless access module, used to connect to the central server;

The data storage module is used to store the explanation matching file and the explanation file, and the explanation matching file has the information of each "explaining position" and the information of each explaining point corresponding to each explaining position;

The bluetooth receiving module is used to receive the position information sent by the iBeacon base station to judge the current "explaining position";

The "explaining position" judging module is used to determine whether the explaining device enters the "explaining position" by comparing the position information broadcast by the iBeacon base station with the information of the "explaining position" in the explaining matching file;

The geomagnetic sensor module is used to judge the direction that the intelligent explanation device faces;

The explaining point judgment module is used to compare the orientation of the intelligent explaining equipment obtained by the geomagnetic sensor module with the explaining position information in the explaining matching file after judging that the explaining equipment enters the "explaining position", and judges what the current explaining equipment is facing Are there any necessary explanation points in the direction of

The playing module is used for playing the explanation file corresponding to the explanation point when it is judged that there is an explanation point in the direction facing the explanation device. The playback module can be downloaded from the central server or comes with the intelligent interpretation device.

The above-mentioned geomagnetic sensor and iBeacon base station are the core components of this system. A geomagnetic sensor, also called a digital compass, is a method of using the geomagnetic field to determine the North Pole. The compass function on the intelligent explanation device is to use the geomagnetic field and the geomagnetic sensor built into the mobile phone to realize the positioning of the geographical direction. Although GPS has a wide range of applications in navigation and positioning, its signal is often affected by the surrounding environment, resulting in a greatly reduced accuracy. Geomagnetic sensors can make up for this defect. Even if GPS information is lost, the system can still work normally. In the present invention, an angle range is set for each direction of the "explaining position", and the direction is determined by determining the range it falls in through the data of the geomagnetic sensor. In the optimal example of the present invention, the angle range is set to 30 degrees, for example, when the geomagnetic sensor data falls within [345-15] degrees, it is judged as the direction "North". The working method of iBeacon is to send its own unique device ID to the surroundings by using the Bluetooth Low Energy (BLE) communication protocol. The iBeacon protocol data is mainly composed of four types of data, namely UUID (Universal Unique Identifier), Major, Minor, and Tx Power. Major and Minor are set by the operator themselves, and both are 16-bit identifiers. In the best example of the present invention, Major is set as the scenic spot ID, and Minor is set as the explanation position ID. The iBeacon receiving device calculates the real-time distance from the iBeacon base station through the Tx Power field and the current BLE signal strength.

In the present invention, in order to implement voice explanation by using geomagnetic sensor equipment, the key information required by the system includes: scenic spot ID, language ID, and explanation location ID. These three ID numbers all occupy 2 bytes (8 bits/byte) in the program. In the present invention, the three kinds of ID numbers play the functions of explaining file search, position matching, direction matching and the like. The specific usage of the ID number is shown in Figure 5 and 6.

The key files required by the system include: explanation matching files, multilingual explanation files, etc. The information of each explanation point corresponding to each explanation position in the scenic spot is saved in the explanation matching file. The teaching point information of each teaching position is saved in the format of "Teaching Position ID + Angle", arranged in sequence according to the serial number, the serial number is the ID number of the teaching position, and the angle is the angle range of the teaching point at the teaching position. The ID number of the explanation location is fixed at 0xFFFF (hexadecimal), which is a specific iBeacon base station at the entrance of the scenic spot, which is used to trigger the intelligent explanation device to download the corresponding key files before entering the scenic spot. The explanation file can be in the form of audio or video, and the explanation file is stored in the intelligent explanation device in the form of a three-level directory. The first-level directory is the scenic spot ID number, the second-level directory is the language ID number, and the third-level directory is the explanation location ID number. The explanation files in the folder are saved according to the file name of "interpretation position ID + angle".

Before the system runs normally, the entire system needs to be initialized and configured, and the explanation matching files corresponding to the scenic spots need to be produced. The initial configuration of the system is shown in flow chart 4. The initial configuration of the system is formed by the staff visiting the scenic spot once along the actual tour route when there is no ready-made explanation matching file. In the initial configuration, the staff accurately records the installation location of the iBeacon base station according to the needs of tourists actually visiting each explanation point in the tour route, that is, determines the specific location of each "interpretation location" in the scenic spot. At the same time, the system assigns a explaining position ID number to each position, and after writing the explaining position ID number into the corresponding iBeacon base station, the iBeacon base station is installed on the corresponding "explaining position". Further, the staff uses the geomagnetic sensor of the intelligent explanation device to obtain the precise angle corresponding to each explanation point on the current "interpretation position". In order to improve the success rate of the direction matching of the intelligent explanation equipment in the navigation stage, the staff needs to convert the precise angle into an angle matching range according to a certain matching range. For example, if the accurate measurement angle is 10 degrees, the angle range converted according to the range of plus or minus 30 degrees is 340 degrees to 40 degrees. After the initialization is completed, the staff will write all the location matching information into a file to form an explanation matching file corresponding to the scenic spot, and upload it to the central server.

The flow chart of the initial configuration of the intelligent interpretation device is shown in Figure 5. Include the following steps:

Step 1. Before tourists enter the scenic spot, turn on the WIFI wireless access module and the Bluetooth receiving module of the intelligent interpretation device.

Step 2. Connect to the central server through the WIFI wireless access module, download and automatically install the explanation software.

Step 3. After the software installation is completed, the tourist chooses the language of the explanation according to the prompt of the explanation software, and the explanation software saves the selected language ID number.

Step 4. The intelligent explanation device receives the specific iBeacon base station information at the entrance of the scenic spot through the Bluetooth receiving module, and obtains the explanation location ID.

Step 5. Judging whether the ID number of the current explanation location is 0xFFFF (hexadecimal), if so, sending the ID number of the scenic spot and the language ID number to the central server.

Step 6. The central server downloads the corresponding explanation file according to the ID number of the scenic spot and the language ID number and saves it in the intelligent explanation device. The initialization and configuration of the intelligent interpretation equipment is completed, and it enters the tour mode.

After entering the tour stage, the smartphone receives the low-power Bluetooth IBEACON protocol signal to find and play the corresponding scenic spot explanation file.

During the tour, the intelligent explanation device side explains the matching synchronization method as shown in Figure 6. Specifically include the following steps:

Step 1. Explain that the software enters the tour mode. When the explaining software receives the broadcast data frame of the iBeacon protocol through the Bluetooth receiving module, it compares it with the previously received iBeacon data to determine whether it has received new iBeacon data, that is, to determine whether the visitor has entered a new explaining position.

Step 2. If a new signal is received, the Major and Minor data are extracted from the broadcast data frame, corresponding to the ID number of the scenic spot and the ID number of the explanation location, respectively.

Step 3. If the scenic spot ID number is different from the previously stored scenic spot ID number, the data frame is discarded.

Step 4. If the ID number of the explanation location is successfully matched, it is judged whether the tourist stays in the direction he is facing for more than 3 seconds.

Step 5. If it exceeds 3 seconds, activate the geomagnetic sensor of the intelligent interpretation device.

Step 6. The specific operation after enabling the geomagnetic sensor is shown in Figure 7. Read the geomagnetic sensor data to obtain the precise angle of the direction that the intelligent interpretation device is facing at the interpretation position.

Step 7. Use the ID number of the scenic spot and the language ID number as the matching path, and use the exact angle as the matching condition to match the explaining point of the explaining position ID within the angle range within which the exact angle falls.

Step 8. If the matching is successful, it means that there are explanation points in the direction here. The "explanation location ID + angle" in the explanation matching file is used as the explanation file name for local search.

Step 9. If the corresponding explanation file is found, play the corresponding explanation file, save the current location information, and perform a new round of explanation judgment.

In addition, the explanation software works like an ordinary multimedia player during the tour. If tourists are not interested in a certain attraction, they can pause the currently playing file and continue to visit the next attraction; if they are interested in a certain attraction, they can manually Play the tutorial file repeatedly.
