Multi-point networking communication system

Abstract

The invention provides a multi-point networking communication system comprising an intelligent control host and an equipment node network. The intelligent control host and the equipment node network form a star network. Point-to-point communication is performed between the intelligent control host and the equipment node network through control instructions. The equipment node network includes countless equipment nodes. A wireless transmit-receive module is embedded in each equipment node to act as the wireless communication hardware basis. The intelligent control host comprises a host node, a core processor and an RF module. The host node is used for processing the serial port instructions of the core processor. When the host requires to communicate with the equipment, the core processor transmits the instructions to the RF module through serial ports, then the RF module wirelessly forwards the instructions to the equipment nodes, and the equipment receives information and then performs processing and feedback according to the respective attribute state. Each equipment node and the host node have a unique equipment address ID, wherein the equipment address ID uses the internal ID of the chip so as to guarantee the uniqueness.

Problems solved by technology

In order to realize the interconnection of all things and the intelligent control of the home, the current communication technology is mainly divided into two technologies: wired communication and wireless communication. The wired communication technology mainly includes communication technologies such as power carrier and RS485. In the past, there were a lot of problems in construction, cost and maintenance when entering a large number of lines. The wireless communication method has comprehensive advantages such as no wiring, low cost, easy expansion, mobility and large capacity. Wireless communication technology has become the general trend. In wireless In the communication technology, there are mainly ZigBee, Z-Wave, WIFI, and RF light wireless communication technology. Z-Wave is a short-distance wireless communication technology based on radio frequency with low cost, low power consumption and high reliability. However, Z-Wave The alliance does not have an opener standard, which restricts the development and expansion of the system. ZigBee technology based on the IEEE 802.15.4 protocol is a short-distance communication standard with short-distance, low complexity, self-organization, low power consumption, low data and Low cost, but ZigBee has limited transmission capacity based on 2.4GHZ, so it is necessary to add relays in the home to expand the network. In addition, the 2.4GHZ frequency band is becoming increasingly crowded, and technologies such as Bluetooth and Wi-Fi all work in this frequency band. Make it necessary to pay attention to bandwidth allocation when using
