Design of universal wireless data monitoring model

For the problem that most existing wireless data monitoring schemes are based on professional fields, have different data requirements, processing methods , safety standards, and high cost of development and application, the paper proposed a design scheme of universal wireless data monitoring model, and introduced overall design of the model and implementation of key technologies. The model uses STC89C52RC as master chip; adopts universal integrated wireless transmission module to transmit and receive data through radio frequency chip nRF24L01; bus module uses RS232 serial data communication method. The test results show that the power of data monitoring module of scene node and the regional dataset module are 8.58 mW and 29.7 mW, transceiver distance of the model is longer than 30 m, which is able to complete reliable and stable wireless data communication.
