Abstract

The invention provides a network communication method, a network communication device and a storage medium, which are used for reducing the number of data packets in a communication network and improving the data transmission efficiency. The network communication method is applied to a video monitoring system, comprises master equipment and slave equipment, and comprises the following steps: the master equipment sends a data packet to the slave equipment, and the data packet comprises a start character, a data length, data content, summation check and an end character and is used for transmitting 0-255 bytes of data; the master equipment receives a response data packet sent by the slave equipment, the response data packet comprises an error response data packet and a correct response datapacket, the response data packet is sent by the slave equipment according to a decoding result of the data packet, if the slave equipment decodes successfully, the correct response data packet is sentto the master equipment, and a correct response code is carried in the correct response data packet; and if the slave equipment fails to decode and confirms that the data packet is the data packet sent to the slave equipment by the master equipment according to the address code carried in the data packet, an error response data packet is sent to the master equipment, wherein the error response data packet carries an error response code.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a network communication method, device and storage medium. Background technique [0002] Network video surveillance is to transmit video information in digital form through wired and wireless IP (Internet Protocol, Internet Protocol) networks and power networks. Video monitoring and recording can be achieved as long as the network can reach, and this monitoring can also be combined with many other types of systems. [0003] At present, commonly used video surveillance protocols include Pelco-D, Pelco-P and other protocols, but the general protocol length is fixed and short, and the content that can be expressed is limited, resulting in an increase in the number of data packets in the network during data transmission, reducing the the efficiency of data transmission. Contents of the invention [0004] Embodiments of the present invention provide a network...
