Intelligent control device special for air source heat pump

Abstract

The invention provides an intelligent control device special for an air source heat pump. The intelligent control device comprises a digital quantity collecting unit, a fault collecting unit, an analog quantity collecting unit, a temperature collecting unit, a relay output unit, a fault output unit, a voice alarming output unit, an analog quantity output unit, a CPU processing unit, a communication interface unit, a periphery communication unit and an equipment information unit. The equipment information unit is connected to the CPU processing unit through the digital quantity collecting unit, the fault collecting unit, a analog quantity collecting unit and the temperature collecting unit, then respectively connected to the relay output unit, the fault output unit, the voice alarming output unit and the analog quantity output unit, and finally connected to a peripheral executing unit in a convergence manner. The intelligent control device has the advantages that the modular integrated design is used, cost and system space can be saved, good filed monitoring and data sharing can be achieved by the voice alarming unit and the communication interface unit which are integrated in the control device, and convenience is brought to maintenance.

Description

1. Technical field [0001] The invention relates to a control device, in particular to an intelligent control device dedicated to an air source heat pump. 2. Background technology [0002] At present, the air source heat pump equipment control system usually uses various PLC controllers. In most cases, it is necessary to expand the system by adding expansion modules, which increases the space occupied by the system and increases the cost. Although a few single-chip controllers can also It meets the initial needs of use, but there is no voice alarm and communication interface. After the equipment fails, it can only be checked manually on site, and it cannot be unattended. It does not meet the trend of high-intelligence production and sales of industrial equipment. 3. Contents of the invention [0003] In view of the deficiencies in the prior art above, the present invention provides a dedicated intelligent control device for air source heat pumps, which can achieve the effec...
