Description

Technical field [0001] The invention relates to a reconfigurable wireless measurement and control network platform based on Zigbee technology, which belongs to the technical field of wireless network communication. Background technique [0002] The advanced wireless industrial measurement and control network integrates sensor technology, embedded system technology, distributed information processing technology and communication technology. It can collaboratively monitor, perceive and collect information about various environments or monitored objects in the network distribution area in real time. The processing of this information to obtain detailed and accurate information and transmit it to the users who need this information is one of the current theories and technology hot research hotspots, and it has a broad technical application prospect. [0003] However, the current domestic industrial measurement and control network technology is still far from the above goals, and wired ...

AI Technical Summary

Problems solved by technology

[0004] There are many unavoidable problems in the wired measurement and control network: the construction of integrated wiring is complicated, and the number of lines increases correspondingly with the increase of the number of platforms

In dense installations, hundreds of lines are intricate and complicated, and the large number of devices will also cause the lines to be too long

Especially in an environment where space resources are tight and a large number of devices (such as lighting, ventilation, air conditioning, etc.) have been placed, reasonable wiring is more difficult

During the wiring process, factors such as the electromagnetic interference generated by the equipment on the line must also be considered, which increases the difficulty of wiring construction.

High cost and short service life

A large number of wires cause a large cost expenditure

In some occasions, due to the harsh environment, the service life of the wire is short, and frequent replacement is required, which increases the cost

Poor flexibility, if the terminal position is adjusted, the wiring needs to be adjusted or even rewired

Poor security. First, if the transmitted data needs to be kept secret, some networks are easy to be stolen

Second, in the occasions where no one is on duty, some lines are very easy to be stolen.

Moreover, the existing Zigbee standard is insufficient for distributed applications where the network structure changes dynamically, and problems such as node loss and routing failure are prone to occur, and the reconfigurability is poor.

Thus affecting the reliability of the wireless measurement and control network
