Plug-and-play scalable radio data collection network and its composing method

Abstract

The plug-play scalable radio data collection network, including the control center and network receiving module connecting with the control center, and the collection module group which is connected with the network receiving module via the radio and distributed in the network, its characteristics are as follows: all collection modules of the described collection module group includes the different name codes and the control center utilizes the name code to connect the response and transfer the collected data with all collection modules. The network can automatically detect and recognize the increase or decrease of the collection modules in this network, and requires no general setting for the hardware (including firmware) in the network modules and can recognize the collection modules without dependence on the working frequency or physical address in the firmware, the network fully depends on the unique name code of the collection modules, so it can realize the scalable plug-play function of the radio data collection network. The invention also provides the network structure method.

Description

technical field [0001] The present invention relates to wireless network communication technology, in particular to a plug-and-play expandable wireless data acquisition network and its composition method. The plug-and-play expandable means that users can pass The wireless data acquisition module is deployed or expanded in a plug-and-play manner, so that specific parameters of any point can be collected at will. Background technique [0002] The use of wireless data acquisition networks in measurement and control systems has become more and more common. Generally speaking, such a data acquisition network is required to have convenient scalability in design, and the network communication protocol conforms to industry standards. When using the wireless network communication method, the network design is generally required to have the ability to automatically monitor the increase or decrease of the acquisition module in the network, and the multi-point communication between the...

Problems solved by technology

[0005] 2. The number of acquisition modules in the network is limited by the number of addresses or frequencies that can be divided, and only a certain number of acquisition modules are allowed to exist in the same network

[0006] This form of network greatly limits the feasibility of users building and changing data acquisition networks according to their needs, which limits the scalability of such networks in practical applications.

In addition, there are no relevant standards, protocols and patents for the plug-and-play scalable design of wireless data acquisition networks in China
