Problems solved by technology

Due to errors in data packet transmission, wrong data packets will be included in the middle of consecutive data packets. When the wireless chip as the receiver receives multiple data packets with continuous content, it cannot restore the entire data, resulting in the data volume exceeding the upper limit of a single data packet. Data cannot be transferred accurately

Embodiment Construction

[0045] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0046] The sending end completes the splitting and encapsulation of the data to be transmitted, adds encoded bytes to the original data, and the receiving end completes the judgment on the order and correctness of the data packets, completes the analysis and assembly of the data, and restores the received data packets into the data to be transmitted.

[0047] When transmitting continuous data with a large amount of data, the sending end and the receiving end need to determine the data amount of a single data packet and the size of the data amount to be sent. This can be done in a way specified by the developer in advance, or it can be communicated and confirmed by the sender and receiver before sending data. After confirming the data volume of a single packet and the total data volume, the total data can ...

Abstract

The invention discloses a wireless data transmission method. The method comprises that a transmitting end and a receiving end communicate so as to determine total data amount and single packet data amount of to-be-transmitted data; the to-be-transmitted data is split into multiple data packets according to the single packet data amount; the multiple data packets are packaged; the transmitting end marks code bytes of the data packets and transmits the data packets; and the receiving end verifies and identifies the marking bytes, confirms that the data packets are received successfully and returns receiving success signals to the transmitting end. According to the wireless data transmission method and system provided by the invention, by packaging the data needing to be split through usage of an algorithm when the data is split and by carrying out splitting and code marking, the receiving end judges whether the data satisfies the format demands of continuous data packets when receiving the data; only the data conforming to conditions can be received; and the accuracy problem when the data of great data amount is transmitted between wireless chips is solved. The method and the system can be widely applied to the field of data transmission.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to wireless data transmission. Background technique [0002] As the concept of the Internet of Things is gradually gaining popularity, the market prospect of Internet of Things products is also broader. The Internet of Things is a network that enables all ordinary physical objects that can be independently addressed to be interconnected. Since an interconnected network is established between physical objects, it is an essential link for physical objects to communicate and communicate through the network. Wireless transmission is the technical basis commonly used in this link. The transmission protocols used for wireless transmission include Zigbee, Bluetooth, UWB, Wifi, etc., and the transmission frequency ranges from Mhz to Ghz; in addition, other chips that use wireless technology for communication, such as RFID radio frequency chips, will also involve Transmission issues to pa...
