Abstract

The invention provides a data sub-packet transmission method. The method comprises the following steps: acquiring to-be-transmitted data and packaging the to-be-transmitted data as a command packet; generating an initial packet, multiple data packets, one ending packet and a packet identification code when the data size of the command packet is greater than the preset data size; filling the initial packet, multiple data packet and the ending packet in order; orderly sending the filled initial packet, multiple data packets and the ending packet to a receiving end; resolving and reorganizing thefilled initial packet, multiple data packets and the ending packet, thereby regenerating the command packet. The data sub-packet transmission method provided by the invention can realize the big datatransmission based on a Zigbee network. The invention further provides a data sub-packet transmission system.

Description

【Technical field】 [0001] The invention relates to the technical field of ZigBee transmission, in particular to a data packet transmission system and method. 【Background technique】 [0002] ZigBee is a low-power LAN protocol based on the IEEE802.15.4 standard. It has the characteristics of short distance, low complexity, self-organization, low power consumption, low transmission rate and low cost. The basic structure of its data message is relatively simple, the maximum transmission of physical layer data is 127 bytes, of which, the MAC (Media Access Control) layer occupies 11 bytes, the network layer occupies at least 8 bytes, and the application layer occupies 8 bytes. bytes, therefore, a data packet can carry up to 100 bytes of application layer data. However, in the actual application process, the user-defined data may be much larger than 100 bytes, which leads to the inability to meet the user's large data transmission requirements using ZigBee transmission technology. ...
