Description

Technical Field

[0001] This invention belongs to the field of noise detection technology, specifically relating to a smart noise reminder robot and method for libraries. Background Technology

[0002] Currently, with the increasing popularity of libraries, more and more people are choosing to go there to research or study. However, noisy situations often occur in libraries, and people inevitably encounter noise interference to some extent during their library study experience. Whether it's loud conversations, ringing cell phones, or other noise sources, these all seriously disrupt the normal study and reading experience.

[0003] In existing technologies, the following three methods are commonly used to reduce noise inside the venue:

[0004] Management patrols: Managers can promptly detect noise and remind the person to keep quiet; this method is more flexible and adaptable to different situations, but it requires a large number of people, necessitates managers to patrol at all times, and involves a high workload.

[0005] Posting reminder signs: This method reminds readers to keep quiet; it is simple and direct and relatively easy to implement, but it is not precise or personalized enough and its noise reduction effect is poor.

[0006] Broadcast reminders: Reminders can be broadcast throughout the library, but this method may cause unnecessary secondary disturbance to some readers.

[0007] In conclusion, regarding the noise problem in libraries, broadcast reminders would cause secondary disturbance to other readers, and therefore are not suitable for widespread use in libraries. While administrator patrols allow for flexible and precise reminders, they are labor-intensive. Text-based reminders can minimize disturbance, but they lack precision. Summary of the Invention

Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0050] Example 1

[0051] Figure 1 This is a schematic diagram of the overall external structure of a library intelligent noise reminder robot provided in one embodiment of the present invention, as shown below. Figure 1 As shown, this embodiment provides a library intelligent noise reminder robot. The robot includes a mobile robot and a main control circuit mounted on the mobile robot. The main control circuit includes a controller, a drive module, a prompting module, and a noise acquisition module.

[0052] like Figure 2 As shown, the drive module is electrically connected to the controller and is used to drive the mobile robot to move; the prompt module is electrically connected to the controller and is used to display prompts; the noise acquisition module is electrically connected to the controller and is used to collect sound signals in the library in real time and transmit the collected sound signals to the controller.

[0053] The controller is used to: determine whether the received sound signal is noise, and if so, determine the location of the noise; obtain the current position of the mobile robot, plan the mobile robot's travel path based on the current position of the mobile robot and the location of the noise, generate a travel control command based on the travel path, and send the travel control command to the drive module, which drives the mobile robot to travel along the travel path according to the travel control command; determine whether the mobile robot has reached the location of the noise, and if so, generate a prompt message and send the prompt message to the prompt module, which displays the prompt message.

[0054] In this embodiment, the noise acquisition module of the present invention collects sound signals in the library in real time, uses a controller to determine whether the sound signal is noise, and can also use the controller to identify the location of the noise. Then, based on the location of the noise and the robot's current position, a travel path is planned, and then the drive module is controlled to drive the mobile robot to the location of the noise along the travel path. When it reaches the location of the noise, a prompting module displays a prompt to remind people who are making too much noise to lower the decibels and maintain a good reading environment in the library, thereby improving the user's reading experience. Furthermore, using the mobile robot to automatically remind people who are making noise can not only reduce the input of human resources, but also improve the noise management effect of the entire library.

[0055] In this embodiment, the mobile robot includes: a body, a pair of wheels at the bottom of the body, a motor inside the body, a drive end of the motor being connected to the drive shaft of the wheels, and a controlled end of the motor being electrically connected to the output end of the drive module. In this embodiment, the drive module uses an L298n driver chip, and the controller can be an STM32 microprocessor or a micro:bit development board.

[0056] As a further optimization of this embodiment, a bracket is provided at the rear of the fuselage, a sign is provided at the top of the bracket, a prompt mark is provided on the surface of the sign, a servo motor is provided inside the fuselage, the bracket is mounted on the drive end of the servo motor, the controlled end of the servo motor is electrically connected to the I / O port of the controller, and the servo motor is used to drive the bracket to rise or fall.

[0057] In this embodiment, the support is slidably connected to the body, and the servo motor can be controlled by the controller. When the mobile robot moves to the location where the noise is generated, the servo motor can be controlled to drive the support to rise. After the sign on the support rises to a certain height, the warning sign on the sign can remind people around to keep quiet. The warning sign can be "Please keep quiet" or "Please do not make loud noises". When the noise is eliminated, the servo motor drives the support to descend and return to the initial position. In this embodiment, the support, the sign, and the warning sign on the sign can be made using 3D printing technology.

[0058] As a further optimization of this embodiment, the prompting module includes: a display screen, which is embedded in the surface of the device body;

[0059] The noise acquisition module includes a pair of microphones, which are respectively installed on the left and right sides of the device body.

[0060] In this embodiment, the display screen is a liquid crystal display (LCD). The prompt module further includes a display driving circuit. The signal input terminal of the display driving circuit is electrically connected to the I / O port of the controller, and the signal output terminal of the display driving circuit is electrically connected to the signal input terminal of the LCD. The display driving circuit can use a VK1072B driver chip. The display screen can display the current decibel level of the sound in the venue in real time, and can also be used to display prompts, such as "Please keep quiet" or "Please do not make loud noises".

[0061] In this embodiment, the microphones are distributed on the left and right sides of the device. Because the distance between the noise source and the two microphones differs, the microphones capture sound at different times. By analyzing the time difference between the two microphones, the direction of the sound can be accurately calculated. The microphones convert audio signals into analog audio signals. Then, an analog-to-digital converter (ADC) chip converts the analog audio signals into digital audio signals. The microphones send the digital audio signals to the controller, which analyzes and processes them.

[0062] In this embodiment, the microphone can be a MIC sound sensor, which is a sensor based on a microphone for sound detection. It can be used to detect the sound intensity in the surrounding environment, has a 300x amplifier, and outputs an analog signal that can be acquired using 3.3V and 5V as references by AD. It can be used to achieve interactive effects based on sound volume, create voice-controlled robots, voice-controlled switches, voice-controlled alarms, etc.

[0063] As a further optimization of this embodiment, the main control circuit further includes: an obstacle detection module, electrically connected to the controller, used to detect obstacle information on the driving path in real time during the process of the mobile robot driving along the driving path, and upload the obstacle information to the controller. The controller is also used to: generate obstacle avoidance instructions based on the received obstacle information, and send the obstacle avoidance instructions to the drive module to control the mobile robot to avoid obstacles.

[0064] In this embodiment, the obstacle detection module can be an ultrasonic sensor. The obstacle detection module can detect obstacles on the driving path, such as pedestrians, bookshelves, tables, chairs, fallen objects, etc., so that the mobile robot can avoid obstacles in time and give way to pedestrians.

[0065] As a further optimization of this embodiment, the main control circuit also includes a power supply module, a camera module, and a temperature and humidity detection module. The camera module and the temperature and humidity detection module are both electrically connected to the controller. The camera module is used to collect environmental image data, and the temperature and humidity detection module is used to detect environmental temperature data and environmental humidity data.

[0066] In this embodiment, the power module provides operating power to the above circuits and is charged wirelessly. The camera module uses a high-definition camera to collect environmental image data, which can be combined with ultrasonic sensors for obstacle avoidance to improve the accuracy of obstacle avoidance. The temperature and humidity detection module uses a temperature and humidity meter to monitor the temperature and humidity values ​​in the room in real time and display them on the screen to improve the robot's practicality.

[0067] In this embodiment, the camera can also identify books on the bookshelves in the library to enable the library's big data retrieval function.

[0068] In this embodiment, the main control circuit also includes an attitude detection module, which includes a gyroscope and an accelerometer, for real-time monitoring of the mobile robot's attitude during movement to ensure that the mobile robot maintains its balance during movement.

[0069] The robot of this invention can be used not only in libraries, but also in natural history museums, science and technology museums and other venues that require quiet environments. It can provide a new solution for management in similar environments, as well as provide reference and inspiration.

[0070] Example 2

[0071] Figure 3 This is a flowchart of a library intelligent noise reminder method provided by one embodiment of the present invention, such as... Figure 3 As shown, this embodiment provides a library intelligent noise reminder method. The method is implemented based on a library intelligent noise reminder robot. The robot includes a mobile robot and a main control circuit mounted on the mobile robot. The main control circuit includes a controller, a drive module, a prompting module, and a noise acquisition module. The drive module, prompting module, and noise acquisition module are all electrically connected to the controller. The method includes:

[0072] Step S10: Acquire the sound signal inside the library and determine whether the sound signal is noise.

[0073] In this embodiment, two microphones of the noise acquisition module are used to collect sound signals within the library. The sound signals include a first signal output by the first microphone and a second signal output by the second microphone. The two microphones send the first and second signals to the controller. The controller can acquire the sound signals within the library and then calculate the intensity of the sound signals, i.e., the decibel value. If the decibel value of the sound signal is less than 30 decibels, it indicates that the reading environment within the library is relatively quiet. If the decibel value of the sound signal is greater than 40 decibels and is continuously generated, or intermittently generated, and the duration is up to 50 seconds, it indicates that the sound signal is noise.

[0074] When the decibel value of the sound signal is less than 30 decibels, it is necessary to use a noise acquisition module to continuously collect the sound signal in the library.

[0075] Step S20: If yes, determine the location of the noise.

[0076] Specifically, determining the location of the noise source includes:

[0077] Step S201: Calculate the propagation time difference between the first signal and the second signal;

[0078] Step S202: Determine the location of the noise source based on the propagation time difference and sound speed.

[0079] In this embodiment, because the distance between the sound source and the two microphones differs, the microphones capture the sound at different times. By analyzing the time difference between the two microphones receiving the sound, the direction of the sound can be accurately calculated. This invention, through sound source localization technology, accurately locates the person generating the noise, achieving precise location and tracking of the noise source.

[0080] Step S30: Obtain the current position of the mobile robot, and plan the travel path of the mobile robot based on the current position of the mobile robot and the location where the noise is generated.

[0081] In this embodiment, the A* algorithm is used for route planning. The A* algorithm, short for A-Star algorithm, combines the BFS and Dijkstra's algorithms and has heuristic characteristics. It guarantees finding a shortest path. Heuristic search involves evaluating each search position in the state space to obtain the best position, and then searching from that position until the target is reached. This eliminates many unnecessary search paths, improving efficiency.

[0082] The A* algorithm includes the following functions: the cost function, which represents the estimated cost of moving from the current node to the target node and is heuristic;

[0083] start: The starting point for path planning;

[0084] goal: The endpoint of the path planning, i.e., the location where the noise is generated;

[0085] g_score: The cost of moving from the current point (current_node) to the starting point (start), where the current point is the current position of the mobile robot;

[0086] h_score: The estimated movement cost from the current node to the target node, without considering obstacles;

[0087] openlist: The list of nodes to be searched during the pathfinding process;

[0088] closelist: A list of nodes that do not need to be retrieved again;

[0089] comaFrom: Stores a list of parent-child node relationships, used for backtracking the optimal path. It is not mandatory and can also be implemented using node pointers.

[0090] In the algorithm's operation, vector graphics cannot be directly imported; a map of equal area needs to be created from the corresponding simulated map. This simulated map can be obtained through camera scanning. In constructing the algorithm's map, raster maps have advantages such as simplicity and unique location, making them convenient for short path planning. Therefore, this embodiment defines a 20×20 raster map based on the original map, where black areas represent obstacles. Simultaneously, the camera establishes the start and end points of the monitored target personnel. Figure 4 As shown.

[0091] Step S40: Generate driving control instructions based on the driving path and send the driving control instructions to the drive module so that the drive module drives the mobile robot to travel along the driving path according to the driving control instructions.

[0092] In this embodiment, after the controller generates a driving control command, the drive module drives the motor to rotate the two wheels according to the driving control command, thereby enabling the mobile robot to travel along the driving path; during the driving process, the method further includes:

[0093] Step S401: Real-time detection of obstacle information on the driving path;

[0094] Step S402: Generate obstacle avoidance instructions based on obstacle information;

[0095] Step S403: Send obstacle avoidance instructions to the drive module to control the mobile robot to avoid obstacles.

[0096] In this embodiment, ultrasonic sensors can be used to monitor obstacle information on the driving path in real time, such as pedestrians, bookshelves, tables, chairs, fallen objects, etc. After detecting an obstacle, the controller generates an obstacle avoidance command so that the mobile robot can avoid the obstacle in time and give way to pedestrians.

[0097] Step S50: Determine whether the mobile robot has reached the location where the noise is generated. If so, generate a prompt and send the prompt to the prompt module so that the prompt module can display the prompt.

[0098] When the mobile robot travels to the location where the noise is generated, the controller controls the display screen of the prompt module to show a prompt message, such as "Please keep quiet" or "Please do not make loud noises".

[0099] Meanwhile, the controller also controls the servo motor, which drives the support frame to rise. After the sign on the support frame rises to a certain height, the sign can remind people around to keep quiet. The sign can be something like "Please keep quiet" or "Please do not make loud noise". When the noise is eliminated, the servo motor drives the support frame to descend and return to its initial position.

[0100] This invention's noise acquisition module collects sound signals within the library in real time. A controller determines whether the sound signal is noise and identifies its location. Based on the noise's location and the robot's current position, a travel path is planned. The drive module then propels the robot along this path to the noise's location. Upon reaching the noise's location, a prompting module displays a warning message to alert individuals to lower their volume, maintaining a pleasant reading environment and improving the user experience. Furthermore, the automatic reminders from the robot to those generating noise reduce manpower and enhance overall noise management within the library. Therefore, this invention offers advantages such as intelligence and precise noise localization, improving the library's learning environment and enhancing reader experience and satisfaction.
