An intelligent temperature control device for an arc combustion furnace body of an infrared carbon and sulfur analyzer

Abstract

The invention discloses an intelligent temperature control device for an infrared carbon-sulfur analyzer electric arc combustion furnace body. The intelligent temperature control device is composed of a DSP, a GPRS module, a Zigbee transmitting and receiving module, a temperature sensor, a semiconductor refrigeration and heating piece and a GPRS network. In the working process, the temperature sensor is installed on the electric arc combustion furnace body and transmits temperature signals to the DSP, the semiconductor refrigeration and heating piece is controlled by a fuzzy algorithm to make the temperature stabilized at 60 DEG C, and temperature information is transmitted to a smart phone through the GPRS module and the Zigbee transmitting and receiving module so that the infrared carbon-sulfur analyzer can be controlled to be started. Intelligent control is achieved through a fuzzy prediction control algorithm, and therefore the control process of the temperature of the electric arc combustion furnace body can be stabilized and reasonable; the Zigbee protocol wireless control is applied, connection lines are omitted, and multiple electric arc combustion furnaces can be detected through a wireless sensor network; the smart phone participates in furnace body temperature control so that the temperature of the furnace body can be more conveniently controlled.

Description

[0001] 1. Technical field [0002] The technical field of the device is automatic temperature control, in particular to an arc combustion furnace body temperature control device used in conjunction with an arc combustion infrared carbon and sulfur analyzer. [0003] 2. Background technology [0004] The content of carbon and sulfur elements in steel has an important impact on its mechanical, physical and chemical properties, so the analysis of element content is an important part of the analysis of trace elements in metal materials. At present, there are many methods for measuring carbon and sulfur elements, such as non-aqueous titration method, conductivity method, gas volumetric method and other chemical analysis methods, which have problems such as low analysis accuracy. Therefore, high-frequency infrared carbon-sulfur analyzers are required for high-precision applications, but high-frequency infrared carbon-sulfur analyzers are expensive, and the cost of the analysis proces...
