Dear All Experts out there! I am doing some researches about the Tor Network, and want to frequently download the consensus data from the Directory Authority Servers (let say 5 minutes each). Thanks to Roya, I know exactly how many Directory authority servers there are in the network, and their IPs. Today, I did read some research papers, there were some experts created tools to get the consensus data from those servers. But it seems to be quite long time ago, out of date, and cannot be used anymore. I would be very grateful if anyone could tell me how or which tool should I use to get the consensus data from those Directory authority servers. Thank you so much for reading my question.

That said, please don't hit the authorities every five minutes! Consensuses are generated hourly, so polling more frequently than that just adds load.
The votes themselves are also hosted at https://collector.torproject.org/archive/relay-descriptors/votes/ where they can be downloaded directly.
