The precise measure on electric furnace electrical parameter is a difficult problem for electric industry, especially for the low-tension heavy current measure. For these reason, the paper introduces a new style of dynamic electrical parameter online measurement system on smelting electric furnace.The system adopts distributary's method to measure heavy current. Using this method can avoid waste material, low precision, fixed difficulty and other shortages. Precise temperature compensation solve the problem that the electrical parameter changed by high temperature. This design unites single chip technology, computer technology and the field data bus technology.The measurement system includes computer detecting system, single chip control system, and CAN bus. The computer detecting system using LabWindows/CVI accomplishes data display, emendation and communications. Electrical parameter measurement select ATT7022, this chip's precision higher and respond rate faster. Monobus numeric temperature sensor "DS18B20 can measure environment and generatrix temperature. Utilizing serial communication CAN-bus establishes corresponding network. This design not only realizes telecommunication and establishing network, but also reduces cost and shortenes design time. The system design inosculates precise distributary's technology, temperature automatic compensation technology and electrical parameter synthetical measurement technology. It can measure many ways heavy current at one time, and solve the difficulty of heavy current measurement. Simple configuration, precise measurement and better expansibility are all merits for this system. Testing result indicates that this system run stability and measure results exactness.
