Full automatic controller of heat exchange unit

Abstract

The invention discloses a full automatic controller of a heat exchange unit. The controller comprises a central processing unit, a digital quantity acquisition unit, an analog quantity acquisition unit, a temperature acquisition unit, a state acquisition unit, a failure acquisition unit, a relay output unit, an analog quantity outputting unit, a temperature adjusting and outputting unit, a pressure adjusting and outputting unit and a failure outputting unit. The central processing unit is connected to the heat exchange unit through the digital quantity acquisition unit, the analog quantity acquisition unit, the temperature acquisition unit, the state acquisition unit and the failure acquisition unit in a wired manner and is provided with an outdoor temperature monitoring interface, a power supply interface, a communication interface and an outer interface. The controller has the advantages that when the controller is applied to the heat exchange unit for full automatic control, the controller is high in adjusting speed and flexibility, stable and reliable in operation, complete in functions, high in adaptability and easy to operate, the energy saving, heat supplying and comfort effects are achieved, and promised application prospect and large social economical benefits are provided.

Description

technical field [0001] The invention relates to the technical field of intelligent controllers, in particular to a fully automatic controller of a heat exchange unit. Background technique [0002] At present, most of the controllers for heating heat exchange units use PLC controllers, but PLC is mainly aimed at industrial applications, such as steel, petroleum, automobiles and other industries, and its application advantages in automatic control of heat exchange units are not obvious. And it is also necessary to add various expansion modules, which not only increases the investment, but also is not conducive to the integrated automatic control of the system. Contents of the invention [0003] The purpose of the present invention is to provide a fully automatic controller for heat exchange units with an integrated structure, which can achieve the effect of unattended operation. [0004] The technical solution adopted by the present invention to solve the technical problem ...
