Intelligent control of electric trace heat

　　With the continuous progress of science and technology, intelligent technology has penetrated into various fields, and the electric accompanying heat system is no exception. As an effective pipeline heating method, electric accompanying heat is widely used in petroleum, chemical, electric power, medicine and other industries. However, the traditional electric accompanying heat system exists high energy consumption, inaccurate control and other problems. In order to improve the efficiency and reliability of electric trace heating system, intelligent control technology comes into being. This paper will discuss the electric accompanying heat intelligent control technology and its application.

　　First, the basic principle of electric accompanying heat

　　The electric accompanies the heat is a kind of technology which uses the electric energy to produce the heat, through the electric accompanies the heat tape to install on the surface of the pipeline, produces the heat after the electricity is energised, compensates for the heat loss of the pipeline, thus maintains the temperature of the medium in the pipeline. Electricity accompanies the heat tape usually consists of conductive material, insulation layer, metal shielding layer and outer sheath. When the current through the conductive material, will produce heat, these heat through the heat conduction way to the pipeline, so as to achieve the purpose of heating.

　　Second, the electric accompanies the heat intelligent control technology

　　In the traditional electric accompanying heat system, usually adopts the manual control or the simple thermostat to control. This way exists the high energy consumption, the control is not precise and so on the problem. In order to overcome the shortcomings of traditional electric accompanying heat system, intelligent control technology is introduced into the electric accompanying heat system. The electric accompanying heat intelligent control technology mainly includes the following aspects:

　　1. temperature sensor: by installing temperature sensor, real-time monitoring the temperature of pipeline surface, and transmit the temperature signal to the control system.

　　2. Intelligent controller: according to the temperature data collected by the temperature sensor, the intelligent controller combines the preset temperature control strategy, automatically adjusts the output power of the electric heating tape, and realises the precise temperature control.

　　3. Communication module: through the communication module, the intelligent controller can exchange data with other equipments to achieve remote monitoring and control.

　　4. Data analysis: through the analysis of the collected data, it can optimise the temperature control strategy and improve the efficiency and reliability of the system. The application of electric accompanying heat intelligent control technology can realise the precise control of electric accompanying heat system, reduce the energy consumption and improve the reliability and safety of the system.

　　Third, the application of electric accompanying heat intelligent control system

　　The electric accompanying heat intelligent control system has been widely used in many fields, the following are several typical application cases:

　　1. Oil and natural gas industry: in oil and natural gas industry, the electric accompanying heat intelligent control system is mainly used to prevent the medium freezing in the pipeline and ensure the normal operation of the pipeline. Through intelligent control, it can realise the precise control of pipeline temperature, reduce energy consumption and improve the reliability of the system.

　　2. Chemical industry: in the chemical industry, the electric accompanying heat intelligent control system is mainly used to prevent the chemical substance in the pipeline from freezing or crystallising, and ensure the normal operation of the production process. Through intelligent control, it can realise the precise control of pipeline temperature and avoid the production accident caused by temperature fluctuation.

　　3. Electric power industry: in the electric power industry, the electric accompanying heat intelligent control system is mainly used to prevent the water or steam freezing in the pipeline and ensure the normal operation of the pipeline. Through intelligent control, it can realise the precise control of the temperature of the pipeline, reduce the energy consumption and improve the reliability of the system.

　　4. Pharmaceutical industry: in the pharmaceutical industry, the electric accompanying heat intelligent control system is mainly used to prevent the freezing of medicine in the pipeline, to ensure the normal production and transport of medicine. Through intelligent control, it can realise the precise control of pipeline temperature and avoid the deterioration of medicine caused by temperature fluctuation.

　　The application of electric accompanying heat intelligent control system not only improves the efficiency and reliability of electric accompanying heat system, but also reduces the energy consumption, reduces the maintenance cost, and makes an important contribution to the safe production and energy saving and emission reduction of various industries.

　　In conclusion, the application of electric accompanying heat intelligent control technology brings new opportunities and challenges for the development of electric accompanying heat system. In the future, with the continuous progress of technology, the electric accompanying heat intelligent control system will be more intelligent, network, automation, for the safety production and energy saving and emission reduction of each industry to make greater contribution.
