[0037] Example 1

[0038] An IoT relay communication controller for wearable physiological parameter monitoring, such as Figure 1 , Figure 2 As shown, it includes a core board, a LoRa wireless automatic networking module, a power supply module, a WAN port, a real-time clock module, a WiFi module, an LTE wireless communication module, and a storage module;

[0039] The LoRa wireless automatic networking module, the power supply module, the WAN port, the real-time clock module, the WiFi module, the LTE wireless communication module, and the storage module are connected to the core board;

[0040] The power supply module is used to supply power to the core board;

[0041] The core board is connected to the cloud platform through the LoRa wireless automatic networking module;

[0042] The wearable physiological parameter monitoring device is connected to the core board through the WAN port, the Wi-Fi module or the LTE wireless communication module;

[0043] The real-time clock module is used to provide an accurate time reference for the core board;

[0044] The storage module is used to store the physiological parameters collected by the wearable physiological parameter monitoring device when the core board is disconnected from the cloud platform.

[0045] In some embodiments, Figure 4 As shown, the LoRa wireless automatic networking module is connected to the core board through the LoRa wireless spread spectrum communication mode to achieve two-way data transmission, with strong anti-interference ability, and the LoRa wireless automatic networking module is connected to the cloud platform through a serial bus. For example, the LoRa wireless automatic networking module and the cloud platform perform two-way data transmission through the RS485 interface, and the LoRa wireless automatic networking module transmits the physiological parameters sent by the core board to the cloud platform through the RS485 interface.

[0046] In some embodiments, the power supply module adopts a Type-C power supply interface. Compared with the traditional USB interface, the Type-C interface has more advantages. The Type-C interface supports forward and reverse plugging, and there is no need to distinguish the front and back of the interface, which improves the convenience of use; the Type-C interface supports higher transmission speeds and greater current output, which can meet the charging and data transmission needs of more devices. In addition, the Type-C interface also supports functions such as video output and audio transmission, which expands its application scenarios.

[0047] There are two main ways to connect Type-C ports: USB-PD and QC. USB-PD is a charging protocol based on the USB Type-C port that supports bidirectional charging, multiple voltage and current outputs, and high charging efficiency; QC is a fast charging technology launched by Qualcomm that is widely used in various mobile devices and has a fast charging speed.

[0048] In some embodiments, Figure 3 As shown, the real-time clock module includes a diode D1, a resistor R1, and a super capacitor C1. The positive electrode of the diode is connected to the VCC_3V3 pin of the core board, the negative electrode of the diode is connected to the positive electrode of the super capacitor and the VCC_RTC of the core board, and the negative electrode of the super capacitor is grounded.

[0049] When the core board is powered on, the supercapacitor is charged through the diode and resistor, and supplies power to the RTC; when the core board is powered off, the supercapacitor is discharged to supply power to the RTC. At the same time, due to the unidirectional conductivity of the diode, no additional discharge will be caused. The use of supercapacitors can quickly store and supply high-power electricity and a large number of cycles without showing performance degradation.

[0050] In some embodiments, Figure 5 As shown, the storage module includes a DDR memory bar and a flash memory chip, and the DDR memory bar and the flash memory chip are connected to the core board. For example, a DDR 2GB memory bar is used, and an eMMC 32GB flash memory chip is used.

[0051] In some embodiments, an indicator light is also included, which is connected to the core board and can be used to indicate the status of the core board, such as communication connection status, storage status, etc.

[0052] In some embodiments, a backup power supply is also included, and the backup power supply is connected to the core board. Since the characterization of the health status of the human body requires long-term and accurate monitoring of physiological parameters, it is necessary to ensure the long-term stable operation of the core board, and a backup power supply can be added to maintain the long-term operation of the core board.

[0053] The physiological parameters that can be monitored by wearable physiological parameter monitoring devices mainly include human blood pressure, heart rate, electrocardiogram, blood oxygen saturation, body temperature, etc. Taking the measurement of human blood oxygen saturation as an example, when the human body is in a state of stillness or steady movement, the collected human blood oxygen saturation signal is effective and can reflect the true blood oxygen saturation of the human body. However, when the human body is in a state of intense exercise, the calculation of blood oxygen saturation will produce a large error. Therefore, it is necessary to judge the human body's movement state when the wearable physiological parameter monitoring device collects signals in order to reduce the error of physiological parameters and ensure the accuracy of physiological indicator judgment.

[0054] In some embodiments, Figure 6 As shown, the wearable physiological parameter monitoring device is provided with an accelerometer. Furthermore, the accelerometer is integrated with an adjustment circuit to adjust the offset voltage of the operational amplifier circuit, offset the voltage introduced by the positive electrode of the operational amplifier due to manufacturing errors, and play a role in circuit voltage stabilization. For example, a LIS3DHH three-axis linear accelerometer is used to measure acceleration. The accelerometer can achieve high integration and has the above-mentioned adjustment circuit integrated inside.

[0055] In some embodiments, Figure 7 As shown, the LTE wireless communication module has a built-in FPC antenna, and the FPC antenna is installed and used inside the module, so that the module has a small size, reliable performance and stable signal.

[0056] The present embodiment provides an Internet of Things relay communication controller for wearable physiological parameter monitoring, which can parse, cache and repackage the data collected by the wearable physiological parameter monitoring device and send it to the cloud platform. When the core board and the cloud platform are disconnected and cannot transmit data in real time, the data collected by the wearable physiological parameter monitoring device can be temporarily stored in the storage module of the core board, and uploaded after the communication between the core board and the cloud platform is restored. This solves the problem that the wearable physiological parameter monitoring device in the related technology adopts a single sensor data wireless transmission method, which is prone to data loss, etc., improves data reliability, reduces dependence on the network, and provides a one-to-many Internet of Things relay communication controller, which can realize data access of multiple wearable physiological parameter monitoring devices and realize true mobile access over a large range.
