Abstract

An electronic coordinatometer, including multiple buses, and multiple connecting plates. The bus is formed by multiple rulers connected via the connecting plates, and the rulers have the same length. The coordinatometer is not affected by environment noise or fluctuation of signal level, and is capable of stably operating in harsh environments. Moreover, the coordinatometer is light and no hoisting equipment is required. Production, transportation and installation of the coordinatometer are convenient.
