Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) advertising technology, and in particular to a smart doorbell advertising system that combines infrared sensing triggering with dual-mode NFC near-field interaction. Background Technology

[0002] With the rapid development of IoT technology, smart advertising machines have become an important means of commercial promotion. Traditional advertising machines mostly use a fixed, looping playback method, lacking effective interaction with viewers and failing to accurately detect the presence of the audience, resulting in limited advertising effectiveness. Although some advertising machines have attempted to incorporate sensing technology, such as the publicly disclosed "Electronic Automatic Voice Advertising System" (CN202075958U), which uses a thermal infrared sensing module to detect human signals and trigger advertising playback, the problem of limited interaction methods and inability to achieve offline-to-online conversion remains.

[0003] In recent years, NFC (Near Field Communication) technology has shown application potential in the advertising field due to its convenient touch interaction characteristics. Related research indicates that integrating NFC technology into advertising systems can enhance user interaction. For example, the study "Research on a Multifunctional Dynamic NFC Advertising System" (Chen Yujun, 2016) proposed a solution combining television advertisements with dynamic NFC tags, allowing users to read detailed advertising information via their mobile phones. However, such solutions have failed to address issues such as the accuracy of advertisement triggering, intelligent broadcast control based on environmental awareness, and how to handle the diversity of user choices.

[0004] Furthermore, existing doorbell advertising devices often suffer from drawbacks such as inflexible sound source control, untimely updates to advertising content, and inability to collect accurate pedestrian traffic data. Therefore, there is an urgent need for a comprehensive advertising solution that integrates human body sensing, intelligent playback control, pedestrian traffic statistics, and flexible NFC interaction. Summary of the Invention

[0005] 3.1 Purpose of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an intelligent doorbell advertising machine system based on infrared sensing and dual-mode NFC interaction, so as to realize accurate triggering, intelligent sorting, diversified interactive conversion and effective data statistics of advertisements.

[0007] 3.2 Technical Solution

[0008] This invention provides a smart doorbell advertising machine system that supports dynamic and global NFC interaction, including: a main control module, an infrared sensing module, an NFC function module, a voice broadcast module, a communication module, and a server.

[0009] The infrared sensing module is used to detect when a person approaches and generate an electrical signal that is transmitted back to the server. The server then sorts and plays the advertisements based on the number of times the signal is transmitted. The infrared sensing module pauses recording the sensing signal during the advertisement broadcast and resumes receiving the signal during the gaps in the advertisement broadcast. It is also configured with an interval time parameter, receiving the sensing signal only within a set time window.

[0010] The NFC function module is integrated into the advertising machine and is configured to operate in at least one of two interaction modes:

[0011] Dynamic Single-Tag Mode: Employing dynamic NFC tag technology, the advertising machine dynamically updates the NFC tag information based on the currently playing advertisement content, enabling different advertisements to correspond to different interactive content and operation processes. When playing audio advertisements, users can directly claim coupons or purchase packages advertised for that advertisement by touching the NFC area with their mobile phones.

[0012] Global Selection Mode: A unique device ID bound to the device is written into the NFC tag. When the user's phone touches the tag, the device ID is read, and a request is sent to the server to retrieve all available advertising coupons or packages on the current advertising machine. These are then displayed uniformly on a single interface for the user to choose from.

[0013] If the user has not registered, both of the above modes will redirect them to a mini-program to complete WeChat one-click registration. After registration, they can continue to complete the receiving or payment process.

[0014] The system adopts a dual-source control architecture. The doorbell volume is adjusted independently via Bluetooth connection to a mobile terminal, while the advertising playback volume is remotely controlled by the server. Both audio sources have the same playback priority. The system's broadcast logic is as follows: when there is a pending advertisement, the advertisement content is played; when there is no pending advertisement, the system's default prompt tone "Hello, welcome" is played.

[0015] The system also features a pedestrian flow statistics function, recording one person's flow each time the infrared sensor detects a pedestrian. During the advertising broadcast, the server records and counts the transmitted parameters. Simultaneously, the doorbell triggers a notification function on the mobile app, allowing users to receive doorbell notifications regardless of their location.

[0016] The main control module can use a 32-bit ARM STM32F103 microcontroller as its control core. The NFC circuit module is connected to the main control module via an I2C communication interface to achieve efficient data exchange and processing. The main control module can also dynamically switch the working mode of the NFC function module according to preset strategies or server instructions.

[0017] 3.3 Technological Innovations and Advantages

[0018] Compared with the prior art, the present invention has the following significant innovations and beneficial effects:

[0019] 1. Dual-Mode NFC Interaction Fusion Mechanism: This innovative mechanism proposes two NFC working modes: dynamic single-tag and global selection. The former enables real-time and precise binding of advertising content with NFC interaction, simplifying the conversion path; the latter provides users with a centralized entry point for all available offers through the device ID, effectively solving the problem of users missing out on desired offers due to improper touch timing. The two modes can be dynamically switched to adapt to complex and ever-changing commercial promotion needs.

[0020] 2. Synergy between infrared sensing and NFC interaction: Combining infrared human body detection with dual-mode NFC near-field interaction not only enables precise triggering of advertisements, but also provides flexible and diverse interactive conversion paths. Through multiple interactions of "sensing + dual-mode touch", user engagement and advertising conversion rate are greatly improved.

[0021] 3. Ad ranking strategy based on pedestrian traffic statistics: The server dynamically adjusts the ad playback order based on the number of infrared sensor readings (i.e., pedestrian traffic), giving ads in high-frequency areas more exposure and improving the utilization efficiency of ad resources. Simultaneously, sensor recording is paused during ad playback to avoid duplicate counting and ensure data accuracy.

[0022] 4. Dual-source independent control system: The system adopts an architecture that separates the doorbell volume and the advertising volume. The doorbell volume can be adjusted independently via Bluetooth, while the advertising volume can be remotely controlled by the server. Both have the same priority, ensuring the clarity of voice prompts and the consistency of user experience in different scenarios.

[0023] 5. Seamless registration and payment process: Users can complete registration and payment by tapping the NFC mini-program, which lowers the barrier to entry for users and realizes a closed loop from offline advertising exposure to online conversion, providing advertisers with a reliable marketing conversion channel.

[0024] 6. Real-time remote notification function: When the doorbell is triggered, the user's mobile APP will receive an instant notification. No matter where the user is, they can maintain a connection with the doorbell device, which expands the usage scenarios and convenience of the device.

[0030] Figure 4 This is a structural diagram of the dual-source control system of the present invention. Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] 5.1 System Hardware Composition

[0033] The hardware components of this system mainly include a main control module, an infrared sensing module, an NFC function module, a voice broadcast module, and a communication module.

[0034] The main control module preferably uses a 32-bit ARM architecture microcontroller, such as the STM32F103 series, which is responsible for data processing and coordination control between modules.

[0035] The infrared sensing module uses a pyroelectric infrared sensor (PIR) installed on the surface of the advertising machine. When a pedestrian enters the detection range, a high-level signal is generated and transmitted to the main control module. The sensor's detection distance is adjustable, typically set to 3-5 meters to adapt to different installation environments.

[0036] The NFC module supports dynamic tag technology, preferably using NXP NTAG series chips, and supports the ISO 14443 Type A standard with a communication distance of 0-5cm. The module connects to the main control module via an I2C interface for data exchange and control. In dynamic single-tag mode, the main control module can dynamically write or switch tag content; in global selection mode, the device ID is permanently stored within the tag.

[0037] The voice broadcast module includes an audio decoding chip and a speaker, supports common audio formats such as MP3 and WAV, and the audio power can be selected from 1W to 10W depending on the application scenario.

[0038] The communication module includes a Wi-Fi / 4G / 5G mobile network and a Bluetooth module, which are used to maintain a connection with the server and mobile terminal to realize data uploading, command receiving and remote notification functions.

[0039] 5.2 Software Logic and Workflow

[0040] System software development includes three parts: device firmware, server backend, and mobile app / mini-program.

[0041] The advertising broadcast control process is as follows:

[0042] After the system starts up, the infrared sensing module begins to detect the surrounding environment. When it detects a human signal, it generates an electrical signal and sends it back to the server.

[0043] The server sorts the ad queue according to the principle of "playing ads with more sensing times" based on the received sensing count data.

[0044] The main control module triggers the corresponding advertisement broadcast based on the sorting results. During the broadcast, the infrared sensing module pauses recording to avoid repeated triggering.

[0045] After a single advertisement is played, the system enters a brief downtime (e.g., 3-5 seconds), during which the infrared sensor module is turned on again to receive new sensor signals.

[0046] If there are no pending advertisements, the system will play the default prompt "Hello, welcome".

[0047] People flow statistics mechanism:

[0048] Each valid infrared sensor reading is counted as one person's flow rate;

[0049] The sensor signals received during the advertisement broadcast will still be recorded and counted by the server, but will not affect the current playback;

[0050] The server generates foot traffic statistics reports periodically (e.g., hourly) to provide data support for evaluating advertising effectiveness.

[0051] Dual-mode NFC interaction process (combined) Figure 3 ):

[0052] Mode selection: The main control module sets the current working mode of the NFC function module according to the policy issued by the server.

[0053] Dynamic single-tag mode process:

[0054] 1. When the advertising machine plays a specific advertisement, the main control module writes the corresponding interaction command (such as coupon ID or package ID) into the NFC tag.

[0055] 2. When a user touches their phone with the NFC area, the system reads a command strongly associated with the advertisement.

[0056] 3. The system checks the user's registration status. If the user is not registered, the system will redirect the user to the mini-program to complete the registration.

[0057] 4. After registration, if a user touches the ad again, the system will directly execute the operation corresponding to that ad (claim a coupon or redirect to payment).

[0058] Global selection mode process:

[0059] 1. When a user touches their phone with the NFC area, the device ID is read.

[0060] 2. The mobile app or mini-program is activated and sends the device ID and user information to the server.

[0061] 3. The server queries the database and returns all active advertising items (including coupons and packages) under that device ID.

[0062] 4. Users will see an "ads menu" list on their mobile phone screen, where they can browse and select one or more coupons to claim, or choose any package to purchase.

[0063] 5. The subsequent user status assessment and payment process are the same as in Mode 1.

[0064] Transaction data from both modes will be recorded and uploaded to the server for performance analysis.

[0065] 5.3 Implementation of Sound Source Control

[0066] The system adopts a dual-source independent control architecture (such as...) Figure 4 ):

[0067] The doorbell alert tone is paired with a mobile device via Bluetooth, and users can adjust the volume individually through the app.

[0068] The volume of the advertisement playback is remotely controlled by the server, and advertisers can set different volumes according to different time periods and environments.

[0069] The two audio sources have the same playback priority and adopt a simultaneous playback mechanism to avoid missing any content.

[0070] The system has a built-in audio processing algorithm that can automatically adjust the audio equalization to ensure clear speech at different volume settings.

[0071] 5.4 Application Examples

[0072] Taking restaurant promotion as an example, the advertising machine continuously plays advertisements for hamburger combos and beverage discounts. When an infrared sensor detects a customer approaching, it triggers a voice advertisement. If the system is in dynamic single-tag mode and a hamburger advertisement is playing, the user can directly purchase the hamburger combo by touching it. If the system is in global selection mode, the user can see multiple options such as hamburger combos and beverage discounts on their mobile phone after touching it, and freely decide whether to claim a beverage coupon or purchase a hamburger combo. The entire process is seamlessly connected, satisfying both precise targeting and respecting user choice, thus maximizing advertising effectiveness.

[0073] 6. Conclusion

[0074] This invention innovatively combines infrared sensing with dual-mode NFC technology to construct an intelligent, flexible, and highly effective doorbell advertising system. The system not only achieves intelligent advertising playback control based on pedestrian traffic statistics but also meets the commercial promotion needs of different scenarios through two NFC interaction modes: "dynamic direct access" and "global selection," greatly improving user experience and advertising conversion efficiency. Simultaneously, the dual-source independent control architecture and real-time remote notification function further enhance the system's practicality and user experience. This invention has broad application prospects and market value, providing innovative advertising solutions for multiple fields such as new retail, community services, and commercial promotion.
