What are the advantages and disadvantages of bonfire transmitting information?
1, come on. In ancient times, flying pigeons passed books, post stations and other ways of transmitting information were very slow.
2, a signal can be transmitted to many places, such as the bonfire party in Beijing, and it can be transmitted to governors everywhere.
Disadvantages of bonfire transmitting information:
1, the biggest disadvantage is that the transmission of information is too simple, and it can only tell the receiver that there is a crisis. As for how the crisis happened and what it needed, I couldn't say it.
2, there are errors, such as a fire near the beacon tower, which is easy to cause misunderstanding by the receiver. In order to please concubines, ancient emperors used gas beacon towers. The local governors thought that the capital was in a hurry and came quickly, but they made a trip in vain.
This has a lot to do with the weather. Fog and other weather with poor eyesight are not easy to spread.
Today, it will pollute the environment and easily cause forest fires.
Extended data:
Beacon is an important means of military communication in ancient frontier defense, and the gas of beacon indicates the emergence of national war. Beacon towers built on the border in ancient times usually put dry wood on the stage, and when there is an enemy situation, they will ignite and give an alarm-quickly transmit information through bonfires between the peaks; In ancient times, there was an allusion that Zhou Youwang laughed it off, played a vassal war and broke his promise in the world, which led to the decline of the Zhou Dynasty.
Regarding the structure and use of beacon towers, the Han bamboo slips unearthed from the beacon towers in Dunhuang and Juyan are interpreted as "four feet high, two feet wide and six feet wide, with a total area of 672 feet and a rate of 237".
Four feet wide and five feet high. Han bamboo slips also show that there were five, six or more people guarding the bonfire at that time, including one director of the bonfire. On weekdays, the guards must have one person to watch, one person to cook, and the rest to build and collect firewood (including firewood for lighting bonfires).
