The existing industrial measurement and control technology has been quite mature, but the model is rather single, and its compatibility with the Internet of things is poor. A design of IoT measurement and control system for optical fiber data transmission is proposed. Based on the principle of optical fiber data transmission, the hardware design and software implementation process of the measurement and control system for IoT are introduced. The single chip computer structure is used to collect the optical signal and store the important data. The main program adopts the multitasking method to realize the system and server serial In order to improve the exchange rate of Internet of Things and reduce the link conflicts during fiber data transmission, the related performance indexes are analyzed based on Markov chain measurement and control algorithm to improve the network performance. The simulation results show that the proposed system design can be connected with the local area network to realize the remote control of the Internet of Things. It is an effective solution to improve the performance of optical fiber data transmission.
