Su Song’s Astronomical Clock Tower as a Distributed Temporal State Engine

תוכן האובייקטים עצמם כתוב באנגלית ועדיין לא תורגם.

תקופה ומקור

Kaifeng, constructed in the late eleventh century and documented in a treatise of the 1090s

מה הוא נבנה לעשות

To generate one regulated stream of timing events and distribute it to an armillary sphere, a celestial globe and time-announcing figures at once.

כיצד המנגנון פועל

Water at approximately constant head fills scoops on a driving wheel. A balance-and-lock mechanism arrests the wheel until a threshold is reached, then releases exactly one step. Stepped shaft motion passes through gearing and an endless chain to every display.

קלט

A water supply at approximately constant head.

טרנספורמציה

Accumulation to a threshold, then a single discrete release - an escapement - with the resulting step distributed by gearing and chain transmission.

פלט

One shared discrete time step driving several heterogeneous astronomical and public displays.

מה הוא מדגים

System integration as the achievement: a regulated event stream with many clients. Direct lineage to European mechanical clocks is debated and is not asserted here.
