Aiming at problem of complex wiring

poor scalability

low signal acquisition and conversion efficiency and poor data transmission ability exist in photoelectric signal acquisition system of some large components hoisting system. Analyze defects of traditional photoelectric signal acquisition system

use technology of wireless sensor networks（ WSNs）

present a new photoelectric signal acquisition system which use STM32F103ZET6 as main controller and nRF24L01 as wireless transmission module. Present implementation methods of hardware and software of the system

and its application in silicon photocell PC50-6 as signal acquisition of sensor parts. The experimental results show that speed and precision of signal acquisition are improved

which can meet the requirements of the system and make certain exploration in application of WSNs in photoelectric signal acquisition.
