Abstract

The invention discloses an electric-power parameter monitoring communication method based on an embedded system and relates to a communication method. The electric-power parameter monitoring communication method based on the embedded system solves the problems that a wireless communication network adopted by an existing power monitoring system is often limited in a self-organizing network, operating power is high and cost is high. The electric-power parameter monitoring communication method is realized based on the embedded operation system Contiki and an electric-power parameter monitoring wireless sensor network. The method comprises the steps of distributing IP addresses for each routing node, each access node and each terminal node, carrying out data transmission among the terminal node, the routing node and the access node by means of the communication protocol 6LoWPAN, carrying out data transmission on the terminal node in the control process of electric-power monitoring parameters by means of the I2C bus protocol, carrying out data transmission on each node in a control process of wireless communication by means of the communication protocol SPI, and carrying out data transmission between the access node and a data management center by means of the communication protocol UART. The electric-power parameter monitoring communication method based on the embedded system is applied to an electric-power system.

Description

technical field [0001] The invention relates to a communication method, in particular to a communication method for monitoring electric power parameters based on an embedded system. Background technique [0002] Electricity supervision and energy-saving transformation first need to monitor electricity information, so as to understand energy usage. Therefore, how to collect and process power information, and realize online monitoring and statistics of users is the key to power monitoring. [0003] With the development of network technology, distributed information collection system based on wired network has become a new means of information acquisition. However, the existence of wired transmission technology in the power monitoring network at present requires high cost of integrated wiring and a large amount of engineering, and there are still problems such as destroying the current status of buildings in the integrated wiring of existing buildings. [0004] In order to me...
