Problems solved by technology

[0004] In colleges and universities, the laboratory is the basic support platform to realize the two major functions of training talents, scientific research, and the two major functions. There are many disadvantages in the traditional experimental teaching platform, which is not conducive to cultivating students' innovative ability. "Open" laboratories can be used in limited resources. Provide students with a place to display their intelligence and develop their individuality, stimulate students' interest in experiments, and cultivate students' innovative consciousness and innovative ability

Embodiment Construction

[0026] An open hot water boiler heating experiment system, including a measurement and control instrument panel 1, a PLC (programmable logic controller) 2, multiple relays 3, a hot water boiler 4, a circulation pump 5, a water supply pump 7, a frequency converter 6, and a conjoined body Water tank 8, radiator 9, such as figure 1 As shown, the hot water boiler 4 is the controlled object of the entire inventive system. After the hot water is heated, it circulates and passes through the radiator 9 to simulate heat dissipation. The cold water returns to the hot water boiler through the circulation pump 5 for heating; the connected water tank is used as water replenishment and control As for the object of the liquid level, the frequency converter 6 controls the voltage of the replenishment pump 7 to control the flow, pressure and liquid level. The control part of an open hot water boiler heating experiment system is as follows: figure 2 , the CPU of PLC (Programmable Controller)...

Abstract

The invention discloses an open-type hot water boiler heating experimental system which comprises a measuring control instrument disc, a programmable controller, a plurality of relays, a hot water boiler, a circulating pump, a make-up pump, a frequency converter, a connecting body water box, a radiator and an upper computer, and the open-type hot water boiler heating experimental system is characterized in that the programmable controller is connected with a controlling quantity output terminal through a system simulation quantity input terminal on the measuring control instrument disc so as to connect with hardware of the whole system; the programmable controller is connected with the upper computer through a serial interface RS485; and the hot water boiler is communicated with the radiator through a hot water pipeline, the radiator is connected with the circulating pump through a hot following pipeline, and the circulating pump is connected with the hot water boiler through a pipeline. The open-type hot water boiler heating experimental system provided by the invention has the advantages of less consuming material, long service life, low cost, reliable and stable performance, convenience in maintenance, and is suitable for being popularized and used in a teaching experiment link.

Description

technical field [0001] The present invention is mainly based on the S7-200 series programmable controller of Siemens Company and the open experiment object platform of the furnace temperature control system of KingView, the configuration software of Yakong Company. Development and design are carried out according to the professional situation to ensure the organic connection with the experiments of related courses. Background technique [0002] In recent years, the research on temperature controllers at home and abroad has become more and more extensive and in-depth. Especially with the development of computer technology, the research and development of temperature controllers has made great leaps and bounds, and a number of commercial temperature regulators have been formed. At the same time, intelligent PID, fuzzy control, adaptive control, etc., are widely used in the technological transformation of temperature control systems and related equipment in enterprises due to t...
