Description

Technical Field

[0001] This utility model relates to the field of intelligent passenger flow statistics technology, specifically to a split-type infrared passenger flow counter, which is suitable for real-time passenger flow monitoring in commercial venues, public passages and other scenarios. Background Technology

[0002] Existing infrared passenger flow counters mostly adopt an integrated design, which has the following technical defects:

[0003] Severe data transmission delay: Due to limitations in battery power and communication module power consumption, data upload intervals can be as long as several minutes or even tens of minutes, which cannot meet the needs of real-time monitoring.

[0004] Single power supply method: The integrated structure relies on a single battery for power supply, which is difficult to support the power consumption of high-frequency data transmission, resulting in a contradiction between device battery life and real-time performance;

[0005] Fixed infrared power: The emission power is fixed, which can easily cause false detections due to ambient light reflection at close range, and missed detections due to signal attenuation at long range, resulting in poor scene adaptability.

[0006] Low network configuration efficiency: It relies on physical buttons or local interface operation, requires repeated on-site debugging, is time-consuming and prone to errors, and is extremely inefficient, especially in large-scale deployments.

[0007] The aforementioned problems severely restrict the accuracy and real-time performance of passenger flow statistics, and there is an urgent need for a solution that balances low power consumption, high adaptability, real-time transmission, and convenient deployment. Utility Model Content

[0008] The purpose of this invention is to provide a split-type real-time infrared passenger flow counter, addressing the shortcomings of existing technologies, and aiming to:

[0009] The adjustable infrared power design solves the dual problems of near-range reflection interference and long-range signal loss.

[0010] The power supply solution is optimized through a split structure, which takes into account both the need for wiring at the detection end and the continuous power supply at the upload end;

[0011] It adopts a Bluetooth master-slave network configuration mode to achieve rapid wireless configuration and improve deployment efficiency;

[0012] By using separate power supply and Bluetooth long-term connection technology, passenger flow data can be uploaded to the server in seconds.

[0013] To achieve the above objectives, this utility model is implemented through the following technical solution: a split-type real-time infrared passenger flow counter, comprising: an infrared transmitter, an infrared receiving data processor, and a data uploader;

[0014] The infrared transmitter includes an infrared emitting unit, an infrared power adjustment unit, and a first power supply unit, used to emit infrared rays and dynamically adjust the infrared emitting power.

[0015] The infrared receiving data processor includes an infrared receiving module, a first wireless communication unit, a second power supply unit, and a data processing module, used to receive infrared signals and process them to obtain passenger flow data, and transmit the data to the data uploader through the first wireless communication unit.

[0016] The data uploader includes a second wireless communication unit, a power adapter unit, and a network communication module, which are used to establish a continuous communication connection with the infrared receiving data processor and upload passenger flow data to the cloud server in real time.

[0017] Both the first power supply unit and the second power supply unit are independent power supply architectures. The data uploader is directly powered by the mains power through the power adapter unit, forming a split power supply architecture.

[0018] The infrared receiving data processor and the data uploader maintain a long-term communication link via Bluetooth Low Energy protocol, enabling passenger flow data to be synchronized in seconds.

[0019] As a further improvement to the technical solution of this utility model, the infrared power adjustment unit is a hardware-level adjustable switch, which is integrated with the infrared emitting unit on the same circuit board. The infrared emitting power can be adjusted in multiple levels to adapt to different detection distance scenarios.

[0020] As a further improvement to the technical solution of this utility model, the network communication module of the data uploader supports encrypted data transmission protocol, and the second wireless communication unit operates in slave mode, sending encrypted network configuration information through the host of the external terminal device to realize wireless network configuration without physical operation.

[0021] As a further improvement to the technical solution of this utility model, the infrared transmitter and the infrared receiving data processor are physically separated structures. The behavior of passengers is captured by directional infrared beam signals, and the first wireless communication unit of the infrared receiving data processor and the second wireless communication unit of the data uploader establish a communication connection within a preset distance range.

[0022] As a further improvement to the technical solution of this utility model, the external terminal device is a mobile application that sends encrypted WIFI configuration information to the data uploader via Bluetooth protocol, and automatically disconnects the Bluetooth connection after completing network configuration.

[0023] As a further improvement to the technical solution of this utility model, the infrared power adjustment unit has a non-linear relationship with the detection distance, and the specific threshold value is dynamically set according to the width of the installation scene and the ambient light.

[0024] As a further improvement to the technical solution of this utility model, the network communication module is not limited to a WIFI module, a 4G module, or other types of modules. It should be noted that the types of network communication modules are diverse and not limited to common WIFI or 4G modules. They also include other network communication modules, such as long-range wireless communication modules (e.g., 2G / 3G / 5G / 6G cellular network modules, LoRa and NB-IoT modules in LPWAN modules, WiMAX modules), satellite communication modules (e.g., GPS / BeiDou modules, maritime satellite / Iridium modules), wired communication modules (e.g., Ethernet modules, PLC modules, serial communication modules), and industrial and special-scenario dedicated modules (e.g., microwave communication modules, RFID modules, custom radio frequency modules), and other types of modules.

[0025] This utility model has the following beneficial effects:

[0026] Improved real-time performance: Through separate power supply and long Bluetooth connection, data can be uploaded to the server within 1-2 seconds, which is two orders of magnitude faster than the traditional solution (minutes).

[0027] Highly adaptable to various scenarios: Dynamic power adjustment covers a detection distance of 1-12 meters, improving the accuracy of passenger flow statistics by more than 40%.

[0028] Ease of deployment: The detection end is wire-free (battery powered), the uploader is powered by AC power, and the contactless Bluetooth network configuration improves efficiency by 80%, making it suitable for rapid deployment in large-scale scenarios. Attached Figure Description

[0038] The present invention will be further described in detail below with reference to the accompanying drawings.

[0039] Reference Figures 1 to 3 This utility model provides a technical solution: a split-type real-time infrared passenger flow counter, comprising: an infrared transmitter 1, an infrared receiving data processor 2, and a data uploader 3.

[0040] 1. Split power supply architecture

[0041] Infrared transmitter 1: includes infrared emitting unit 11, infrared power adjustment unit 12 and first power supply unit 13 (replaceable battery, independently powered), used to emit infrared rays and dynamically adjust the emission power, supports wiring-free installation, and low power consumption design ensures several months of battery life.

[0042] Infrared receiving data processor 2: includes an infrared receiving module 21, a first wireless communication unit 22 (Bluetooth low power), a second power supply unit 23 (replaceable battery, independently powered) and a data processing module 24, used to receive infrared signals, process passenger flow data, and communicate with the data uploader 3 via Bluetooth.

[0043] Data uploader 3: includes a second wireless communication unit 31 (low-power Bluetooth slave), a power adapter unit 32 (connected to AC power for direct power supply) and a network communication module 33 (supports encrypted data transmission), used to establish a long connection with the infrared receiving data processor 2 and upload passenger flow data to the cloud server in real time.

[0044] 2. Dynamic infrared power adjustment technology

[0045] The infrared power adjustment unit 12 is a hardware-level adjustable switch (such as a DIP switch) integrated with the infrared emitting unit 11 on the same circuit board. It supports multiple levels (such as 4 levels) of infrared emission power adjustment. The level and the detection distance have a non-linear relationship. It can be dynamically set according to the width of the installation scene and the ambient light, thus solving the problems of near-distance reflection interference and long-distance signal attenuation.

[0046] 3. Bluetooth long-connection real-time transmission mechanism

[0047] The infrared receiving data processor 2 and the data uploader 3 maintain a long-term communication link through the Bluetooth Low Energy protocol. Data is transmitted as soon as it is triggered, with a transmission delay of ≤2 seconds, enabling passenger flow data to be synchronized to the cloud in seconds.

[0048] 4. Contactless Bluetooth pairing

[0049] The data uploader 3 operates in Bluetooth slave mode. External terminal devices (such as mobile applications) act as hosts to send encrypted WIFI configuration information. Network configuration can be completed without physical operation and takes effect within 5 seconds. The Bluetooth connection is automatically disconnected after network configuration, improving the efficiency of large-scale deployment.

[0050] Example: Split power supply architecture:

[0051] Passenger flow counting terminal (infrared transmitter 1 and infrared receiver data processor 2): It is powered by an independent battery, supports wiring-free installation, and its low power consumption design ensures several months of battery life;

[0052] Upload end (data uploader 3): External 220V AC power ensures continuous operation of Bluetooth and network modules and supports real-time data transmission.

[0053] Technical benefits: Completely separates the high-power module (network communication) from the low-power module (infrared detection), breaking through the power supply bottleneck of integrated design and achieving a balance between real-time performance and battery life.

[0054] Dynamic infrared power adjustment technology:

[0055] The infrared transmitter 1 has a built-in DIP switch that supports multiple power levels (such as 4 levels) and the emission intensity is controlled at the hardware level through the PCB board.

[0056] Scene adaptation: Select the corresponding power level according to the installation width (e.g., 1-12 meters). Reduce power at close range to avoid reflection interference, and increase power at long distance to ensure signal stability.

[0057] Technical Results: Covers multiple detection scenarios, improving passenger flow statistics accuracy by over 40% (see appendix). Figure 1 (Gear positions and circuit implementation method).

[0058] Bluetooth long-connection real-time transmission mechanism:

[0059] The infrared receiving data processor 2 and the data uploader 3 communicate via a Bluetooth BLE long connection. Data is transmitted immediately upon triggering, with a transmission delay of ≤2 seconds.

[0060] The data uploader 3 has a built-in network module that synchronizes data to the cloud in seconds via TCP protocol, and the front-end software is updated in real time.

[0061] Technical effect: Compared with the traditional solution (upload time in minutes), the real-time performance of data is improved by two orders of magnitude.

[0062] Contactless Bluetooth pairing:

[0063] The uploader operates as a Bluetooth slave, while the mobile app acts as the host to send encrypted Wi-Fi information. After entering the Wi-Fi information in the app, the network configuration is completed automatically without any physical operation, and it takes effect within 5 seconds.

[0064] Technical benefits: Distribution network efficiency improved by 80%, especially suitable for large-scale commercial deployments (see appendix). Figure 2 Interaction flow).

[0065] It should be noted that the appendix Figure 1The circuit diagram shows the infrared transmission power levels and their implementation. The infrared transmission power is divided into 4 levels. With all 3 DIP switches off, the default is level 1. Turning on the 1st DIP switch and turning off the others adjusts the level to level 2. Turning on the 2nd DIP switch and turning off the others adjusts the level to level 3. Turning on the 3rd DIP switch and turning off the others adjusts the level to level 4. The higher the level, the higher the infrared transmission power, and the wider the corresponding door or passage.

[0066] Hardware installation in this embodiment:

[0067] Infrared transmitter 1 and infrared receiving data processor 2: fixed to both sides of the door or passage by adhesive backing or brackets to form a directional infrared beam structure.

[0068] Data uploader 3: Connects to 220V AC power and is installed within 10 meters of the infrared receiving data processor 2 (effective Bluetooth communication distance).

[0069] Power regulation

[0070] Adjust the infrared power adjustment unit 12 according to the channel width (e.g., 1-12 meters) and ambient light using the DIP switch:

[0071] Level 1 (default): Suitable for close-range distances of 1-3 meters (low power, anti-reflection interference);

[0072] 2-4 levels: Power increases with each level, suitable for distances of 3-12 meters (high power, anti-signal attenuation).

[0073] Distribution network operation

[0074] Open the mobile application and search for the Bluetooth signal of data uploader 3;

[0075] Enter the WIFI account and password or use the 4G network, and the program will automatically send the encrypted information to the second wireless communication unit 31 of the data uploader 3;

[0076] After network configuration is completed, the Bluetooth connection is automatically disconnected, and the data uploader 3 connects to the cloud via the network communication module 33.

[0077] Data transmission

[0078] After the infrared receiving data processor 2 detects the passenger flow signal, the data processing module 24 generates passenger flow data;

[0079] Data is transmitted via a long-term connection between the first wireless communication unit 22 (Bluetooth host) and the second wireless communication unit 31 (Bluetooth slave) of the data uploader 3;

[0080] The data uploader 3 uploads data to the cloud server in real time via the network communication module 33 (such as TCP protocol), and the front-end software refreshes and displays the data in real time.

[0081] It should be noted that the network communication module 33 is diverse in type and is not limited to common WIFI or 4G modules. It also covers other network communication modules, such as long-distance wireless communication modules (e.g., 2G / 3G / 5G / 6G cellular network modules, LoRa and NB-IoT modules in LPWAN modules, WiMAX modules), satellite communication modules (e.g., GPS / BeiDou modules, maritime satellite / Iridium modules), wired communication modules (e.g., Ethernet modules, PLC modules, serial communication modules), and industrial and special scenario-specific modules (e.g., microwave communication modules, RFID modules, custom radio frequency modules), and other types of modules.
