System and method for serial network data communication of single-host wireless devices

Abstract

The invention discloses a system and method for data communication in series networking of a single host wireless device, comprising a host and multiple slaves, the host and multiple slaves are connected sequentially through a serial wireless network, the host Convert the data information into data in the target data format for transmission, the slave receives the data in the target data format and relays and responds, and transmits the data to the last slave, which converts the data into a response Formatted data to respond to the host. This method is suitable for use in a simple serial network, where the amount of data is small and the real-time requirements are not high. It can effectively acquire and transmit data, not only has strong anti-interference ability, but also is simple, reliable and low in cost.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a system and a method for serial network data communication of a single host wireless device. Background technique [0002] At present, in the long-distance long-distance wireless equipment network communication, the equipment is often made into a linear connection. In this series of wireless network equipment, adjacent lines are prone to interference, which makes it impossible to effectively transmit data from a certain node. to another node. If a node in the middle fails, the data cannot effectively skip the point of failure and continue to be transmitted, resulting in communication interruption. When each slave device sends the data sent by the master device at the same time, it will cause multiple transmissions, the data will be sent repeatedly, and the target device will receive the data sent by the master device multiple times, resulting in repeated data reply prob...

Problems solved by technology

[0002] At present, in the long-distance long-distance wireless equipment network communication, the equipment is often made into a linear connection. In this series of wireless network equipment, adjacent lines are prone to interference, which makes it impossible to effectively transmit data from a certain node. to another node

If a node in the middle fails, the data cannot effectively skip the fault point and continue to be transmitted, resulting in communication interruption

When each slave device sends the data sent by the master device at the same time, it will cause multiple transmissions, the data will be sent repeatedly, and the target device will receive the data sent by the master device multiple times, resulting in repeated data reply problems

Or the wireless signal sent by the adjacent serial wireless network is received by the terminal of the wireless network device in this group and sends data down, causing the receiving end of the device in this group to receive wrong data
