你好,我正在开发一个无线模块EMG,用于截肢者,它将由一些无线模块组成,每个模块具有灵活的有线信道数:“本地的----- -----线(I2C)----- [EMG信道1 ]中心))(模块1)-------线(I2C)-----[EMG通道2 ]处理…(i)(无线)(局部)----- -----线(I2C)----- [EMG通道M-1 ]模块N-----线(I2C)-----[EMG通道M ]每个香奈儿将在16位2kSPS下获得。考虑到每个本地模块的4个EMG通道,它需要192kbp的数据速率[(16bit数据+8位前导)*4CH*2kss]。因此,该项目的要求是:每个模块至少需要192kbps的数据速率——不需要很大的距离(只有几厘米)- Low功率(每个模块都非常低)。大小和电池供电)-时间依赖性(模块需要同步或至少发送带有时间戳的数据)-非常低的延迟(100Ms最大),我是新手,与无线接口一起工作,所以我会感谢一些已经做过类似项目的人的意见,比如什么样的技术No理学(蓝牙、ZigBee、Z波、亚GHz)、制造商、通用提示、ETCRY!!!!

Hello,
I'm developing an wireless modular EMG for amputee that will consist of some wireless modules, each module with a flexible number of wired channels:
| Local | ------- Wire (i2c) ---------- [EMG Channel 1]
|Central | ))) wireless ))) | Module 1 | ------- Wire (i2c) ---------- [EMG Channel 2]
|Processing| ...
|Block | ))) wireless ))) | Local | ------- Wire (i2c) ---------- [EMG Channel m-1]
| Module n | ------- Wire (i2c) ---------- [EMG Channel m]
Each chanel will be acquired at 16bit 2ksps. Considering 4 EMG chanels per local module it would need 192kbps of data rate [(16bit data + 8bit preamble)*4ch*2ksps].
So the requeriments for the project is:
- at least 192kbps of data rate for each module
- No need for great distances (just few cen
timeters)
- Low power (each module will be very low size and battery powered)
- Time dependant (the modules needs to be synchronized or at least send data with a timestamp)
- Very low delay (100ms maximum)
I'm newbie working with wireless interface, so i would appreciate opinions from someone who already did some similar project, like what kind of technology (bluetooth, zigbee, z-wave, sub ghz), manufacturer, general tips, etc
Thank!!!
