Embodiment Construction

[0026] The present invention will be further explained below in conjunction with the drawings;

[0027] in figure 1 Among them, the ZigBee-to-power line carrier gateway technology is composed of a power carrier transceiver circuit 3, a microprocessor 1, and a coupling transformer 2. It is characterized in that the entire gateway is connected to the coupling transformer 2 from the power line 1 in turn from the left to the right. The transceiver circuit 3, the microprocessor B4, the microprocessor A5, the ZigBee 2.4GHz transceiver circuit 6, the omnidirectional antenna or the directional antenna 7, and the distribution of peripheral circuits. In specific implementation, the power carrier transceiver circuit and the microprocessor A are connected to realize the physical layer, MAC layer and network layer of the power line communication terminal. The data packet received from the power line communication terminal is transmitted to the microprocessor B through the I2C, UART and other ...

Abstract

The invention relates to a ZigBee transfer power line carrier wave gateway technology, consisting of a power carrier wave transmitting and receiving circuit, micro-processors and a coupling transformer, a data packet received from a power line communication terminal is transmitted to a micro-processor B by interfaces such as I2C, UART and the like located between a micro-processor A and the micro-processor B. ZigBee 2.4GHz transmitting and receiving circuit and the micro-processor B realize ZigBee protocol of ZigBee communication terminal, the user data packet transmitted from the micro-processor A is transmitted out by ZigBee communication, thus achieving the aim of the ZigBee transfer power line carrier wave gateway. The invention has the characteristics of simple application, long cell service life, networking capability, high reliability, low cost and the like.

Description

Technical field: [0001] The present invention relates to the field of electronic technology, in particular to the ZigBee-to-power line carrier gateway technology. Background technique: [0002] ZigBee technology is a low-cost, low-rate, low-power wireless transmission technology. It is based on the IEEE802.15.4 standard. The operating frequency is 868MHz, 915MHz or 2.4GHz, which is an open frequency. Compared with several other wireless communication technologies, such as Wi-Fi and Bluetooth, ZigBee is characterized by simple application, long battery life, networking capability, high reliability and low cost.
