Description

1. Technical Field: [0001] The invention relates to a device for collecting and processing high-speed signals and wireless communication, in particular to a wireless sensor network node with a high sampling rate for building a wireless sensor network system. 2. Background technology: [0002] Currently, wireless sensor network technology is an important research field that has been widely concerned by domestic and foreign researchers. The concept of wireless sensor network is based on a simple equation: sensing technology + central processing unit + wireless communication = thousands of potential applications. When it is necessary to continuously sense, test, and transmit wireless signals to environmental parameters such as temperature, luminous flux, displacement, and noise, consider configuring an intelligent wireless sensor network in the relevant field to measure the environmental parameters to be measured. Sensor data analysis to achieve the purpose of detection. This techno...

[0006] However, the current structural health monitoring technology based on the active monitoring method uses a high excitation signal frequency (100Ksps-500Ksps or even higher), and there is no wireless sensor network node with a high-speed sampling rate that meets the above requirements. The highest wireless sensor network node at home and abroad The sampling frequency is within 100Ksps, and the existing general-purpose high-speed test system is complex in structure and bulky, and cannot be combined with wireless sensor network technology. Therefore, it is necessary to design and develop a high-speed sampling rate wireless Sensor network nodes, and use this to build a wireless sensor network with a wider range of applications
