Abstract :
A short-distance wireless transmission program of laser echo signal was proposed to solve the problems: atrocious conditions, wiring in need of special protection, the cost of higher. The digital echo signal was transmitted into embedded single-chip LPC2880, through the wireless transmission module PTR4000, the signal was transmitted to the receiving system. Receiving system will receive the signal and transmit through the Ethernet interface to the PC machine. The echo signal will be stored on the computer in the form of file, According to the demand, the echo signal spectral analysis can be carried, signal and power spectrum will be real-time displayed in the form of graph. The experimental results show that: PC machine can correctly convey control commands, acquisition system can accept PC instructions correctly, implement the process of wireless acquisition, the measured data can be transmitted through the Ethernet interface to PC machine.
