Problems solved by technology

At present, in the normal production process of domestic and domestic coke ovens, hand-held optical thermometers are generally used for manual measurement. The human errors in the measurement accuracy are large, and the working environment is poor, especially the closed-loop automatic control of the coke oven heating model cannot be satisfied. requirements, resulting in the coke oven heating automatic control system cannot be effectively realized
Although people have recognized the importance of automatic temperature measurement very early, some pre-embedded temperature sensors and the method of installing fixed optical probes have been used in recent years, but due to the large number of installed sensors (probes), the accuracy error among many sensors Large, resulting in large measurement errors, due to the large number of sensors, the reliability has dropped sharply, the cost is still high, and it is impossible or difficult to replace and maintain after installation (influenced by the structure of the coke oven), so it has not been used in the normal production of coke ovens. The heating control system is adopted, but the one-time pre-embedded temperature sensor method is only used in the oven stage of the coke oven start-up process
Therefore, the current manual measurement can no longer meet the needs of the development of the coke oven control system in the future.

Abstract

A temp measuring system of coke-oven consists of ring rail, automatic temp measuring unit with optical probe, communication head and top position computor. The measuring method includes carrying out real measurement by scanning temp inside oven at measuring hole on vertical fire channel, transmitting measured data to top position computer through cabled communication line, calculating out temp for each vertical fire channel and controlling coke-oven heating system.

Description

technical field [0001] The invention relates to a temperature measuring method and a temperature measuring device thereof, in particular to an automatic coke oven temperature measuring method and a temperature measuring system thereof. Background technique [0002] Temperature control is the key to the production control of a coke oven. The accuracy of temperature control will directly affect the quality of coking products and the life of the coke oven. In the coke oven heating system, temperature measurement is the core of the coke oven heating control system. At present, in the normal production process of domestic and domestic coke ovens, hand-held optical thermometers are generally used for manual measurement. The human errors in the measurement accuracy are large, and the working environment is poor, especially the closed-loop automatic control of the coke oven heating model cannot be satisfied. requirements, resulting in the coke oven heating automatic control system ...
