本实用新型涉及一种脉搏信号测量装置，具体地说，涉及一种射频无线脉搏信号测量装置，属于脉搏信号测量领域。The utility model relates to a pulse signal measuring device, in particular to a radio frequency wireless pulse signal measuring device, which belongs to the pulse signal measuring field.

背景技术Background technique

脉搏信号不仅为人体提供生理参考信息，而且它本身也能给出许多有价值的诊断信息。采用传感器测量脉搏并利用计算机技术、现代信号处理技术和人工智能技术，可以客观地记录和处理脉搏信号，有利于脉搏信号的存储、分析和识别。The pulse signal not only provides physiological reference information for the human body, but also can give a lot of valuable diagnostic information itself. Using sensors to measure the pulse and using computer technology, modern signal processing technology and artificial intelligence technology can objectively record and process the pulse signal, which is beneficial to the storage, analysis and identification of the pulse signal.

目前通常采用固定的专门仪器测量脉搏信号，仪器主要是通过PCI并行或串行口以有线的方式传递数据。脉搏信号实时监视装置（申请号为201020210926.0）公开了一种用串行口通信传输数据的脉搏信号检测装置；基于通用串行总线的脉搏信号检测装置（申请号为201020210929.4）公开了一种用通用串行总线传输数据的脉搏信号检测装置。有线信号传输方式信号容易衰减和受电磁干扰，导致测量的数据失真，而且限制了被测对象的活动空间。可扩展性差且不易维修。另外目前通用串行总线的最佳传输距离为5米，否则数据传输会不稳定。无线数据测量和传输技术可以减少系统间的电缆连接,具有分布灵活、不受空间条件限制、携带方便等优点, 在各种实时监测、野外操作和特殊的场合应用广泛。At present, a fixed special instrument is usually used to measure the pulse signal, and the instrument mainly transmits data in a wired manner through the PCI parallel or serial port. Pulse signal real-time monitoring device (application number 201020210926.0) discloses a pulse signal detection device that uses serial port communication to transmit data; pulse signal detection device based on universal serial bus (application number 201020210929.4) discloses a A pulse signal detection device for serial bus transmission data. The wired signal transmission method is easy to attenuate the signal and be subject to electromagnetic interference, which leads to the distortion of the measured data and limits the activity space of the measured object. Poor scalability and difficult to repair. In addition, the best transmission distance of the current universal serial bus is 5 meters, otherwise the data transmission will be unstable. Wireless data measurement and transmission technology can reduce the cable connection between systems, has the advantages of flexible distribution, not limited by space conditions, and easy portability, etc., and is widely used in various real-time monitoring, field operations and special occasions.

It uses a highly integrated process to integrate the piezoelectric film, sensitivity temperature compensation element, temperature sensing element, and signal conditioning circuit into the sensor, and outputs an analog signal and a complete analog voltage signal. The pulse sensor is connected to the analog-to-digital conversion pin of the radio frequency wireless module A.

射频无线模块用Nordic VLSI公司的SoC集成化RF芯片nRF9E5实现。它内置nRF905 433/868/915MHz收发器、8051兼容微控制器和4输入10位80ksps A/D转换器。内置nRF905收发器与nRF905芯片的收发器一样，可以工作于ShockBurst(自动处理前缀、地址和CRC)方式。内置电压调整模块，最大限度地抑制噪音，为系统提供1.9～3.6V的工作电压，QFN5×5mm封装，载波检测。它提供SPI和UART接口。由于nRF905功耗低，工作可靠，因此很适用于无线数据传输系统的设计。射频无线模块A实现数据处理和无线发送，射频无线模块B实现数据接收，分别采用nRF9E5通信芯片。射频无线模块B与计算机之间通过UART端口相连。The radio frequency wireless module is realized with the SoC integrated RF chip nRF9E5 of Nordic VLSI Company. It built-in nRF905 433/868/915MHz transceiver, 8051 compatible microcontroller and 4-input 10-bit 80ksps A/D converter. The built-in nRF905 transceiver is the same as the nRF905 chip transceiver, and can work in ShockBurst (automatically handle prefix, address and CRC) mode. The built-in voltage adjustment module suppresses the noise to the greatest extent, and provides a working voltage of 1.9~3.6V for the system, QFN5×5mm package, carrier detection. It provides SPI and UART interface. Due to the low power consumption and reliable operation of nRF905, it is very suitable for the design of wireless data transmission system. The radio frequency wireless module A realizes data processing and wireless transmission, and the radio frequency wireless module B realizes data reception, using nRF9E5 communication chip respectively. The radio frequency wireless module B is connected with the computer through the UART port.

由于数据测量部分具有随身携带要求， 因此电源A采用纽扣电池，为射频无线模块A供电。Since the data measurement part is required to be carried around, the power supply A uses a button battery to supply power for the radio frequency wireless module A.

计算机用来显示、记录和存储传输过来的脉搏信号。通过串行接口与射频无线模块B相连。The computer is used to display, record and store the transmitted pulse signal. Connect with radio frequency wireless module B through the serial interface.

电源B采用+3V直流电源，为射频无线模块B供电。The power supply B adopts +3V DC power supply to supply power for the radio frequency wireless module B.

nRF9E5使用Nordic VLSI公司的ShockBurst的特性进行高速的数据传输。ShockBurst实现低速数据输入，高速数据输出，从而降低了系统的平均能耗。在ShockBurst接收方式下，当收到一个有效地址的射频数据包时，地址匹配寄存器位（AM）和数据准备好寄存器位（DR）通知片内单片机把数据读出。在ShockBurst发送方式下，nRF9E5自动给要发送的数据加上前缀和CRC校验。当数据发送完后，数据准备好寄存器位（DR）会通知单片机数据已经处理完毕。nRF9E5 uses the characteristics of ShockBurst of Nordic VLSI Company for high-speed data transmission. ShockBurst realizes low-speed data input and high-speed data output, thereby reducing the average energy consumption of the system. In the ShockBurst receiving mode, when a radio frequency data packet with an effective address is received, the address matching register bit (AM) and the data ready register bit (DR) notify the on-chip microcontroller to read out the data. In the ShockBurst sending mode, nRF9E5 automatically adds a prefix and CRC check to the data to be sent. When the data is sent, the data ready register bit (DR) will notify the MCU that the data has been processed.

当系统没有发送和任务时，其进入空闲方式，nRF9E5在空闲方式下，一旦有任务要处理时，其能够在很短的时间内就进入ShockBurst接收方式和ShockBurst发送方式。空闲方式下，晶体振荡器依然工作，配置字中的内容不至于丢失。When the system has no sending and tasks, it enters the idle mode. In the idle mode, nRF9E5 can enter the ShockBurst receiving mode and ShockBurst sending mode in a very short time once there are tasks to be processed. In the idle mode, the crystal oscillator still works, and the content in the configuration word will not be lost.
