In order to reduce the delay of Internet of things(IoT) information communication on the customer side, a delay compensation system of IoT information communication on the customer side based on smart programmable logic controller(SPLC) is designed. The information acquisition module uses smart meters and sensors to collect the IoT information at the customer side of the power grid, and the information is transmitted to the information communication control module through the Modbus gateway communication protocol of the wireless network. The module uses the SPLC sub module to receive the communication command sent by the terminal of the information processing sub module, and completes the communication control through the programmable logic controller(PLC) with the support of the microcontroller. If the information has a communication delay, the distributed delay compensation algorithm based on grey prediction is adopted to realize the delay compensation of IoT information communication on the customer side, and the compensated IoT information on the customer side is transmitted to the user module for presentation to the user. The experimental results show that the proposed system has a good performance of IoT information communication, and the communication advantages are more significant under large-scale customer side IoT information communication. It can timely compensate the network IoT information communication delay and improve the real-time communication.
