Preface
Recently, I was entrusted by some domestic scientific research institutes , Helped develop a wearable neural signal and behavioral data analysis device for birds . Although the project was successful . But there are also many problems worth recording and reflection .
As a smart wearable solution provider , Sort out the technologies in this field , Accumulate and review . It will help us to make products that more meet the needs of users .
Analysis of technical difficulties
DSP Processing technology ：
Bird wearable neural signal analyzer is designed to collect multiple signals adc Collected , And filter and reduce the noise of the collected signal . Some digital signal processing algorithms are applied here . Most of them are within our capability , However, some resources are quite expensive , When optimization is needed . It will take a lot of time . This really took a lot of time .
Multisensor algorithm fusion technology ：
The most important thing of the neural signal analyzer is to collect various signals of birds , Sensors are indispensable here . Because of the growing popularity of sensors , It makes many of the devices more intelligent . We are based on neural signal acquisition , Optional motion sensors are added ,GPS Position sensor , Health sensors, etc . The introduction of these sensors , Make the device more practical and intelligent .
Internet of things technology ：
In recent years, , With the rapid development of wireless communication technology , Wireless technology has become very popular . With 4G,5G technology , wifi technology , A variety of wireless technologies with Bluetooth technology as the core have been developed at low cost Application , These greatly improve the function and application scope of wearable neural signal analyzer . With the help of the latest communication technology , The device can realize data collection in both local and remote situations . Make data collection more timely .
Ultra low power consumption MCU technology ：
Wearable neural signal analyzer needs to be worn on birds , Therefore, the power consumption requirements are particularly high . So ultra low power consumption mcu Technology becomes very important . With the development of chip technology , Ultra-low power consumption mcu It is only in these years that technology has made great breakthroughs . Use the latest mcu technology , The power consumption experience of the product has risen to a higher level .
Future outlook
The algorithm is intelligent
With the multi-sensor data acquisition , Local processing of data is becoming more and more urgent , We have developed practical mcu Running algorithms , It will make the system easier to use .
Scene customization
According to the needs of different scenarios , In the future, we should make these products more targeted , And the circuit is becoming more and more personalized . Special needs that are more practical for specific scenarios .
