Special controller for air source heat pump

Abstract

The invention provides a special controller for an air source heat pump. The special controller for the air source heat pump comprises a digital acquisition unit, an analog acquisition unit, a temperature acquisition unit, a high-speed pulse acquisition unit, a relay output unit, a fault output unit, a voice alarm output unit, an analog output unit, a CPU (central processor unit) and a free-port communication interface unit. The digital acquisition unit, the analog acquisition unit, the temperature acquisition unit and the high-speed pulse acquisition unit are connected to the CPU and are connected to the relay output unit, the fault output unit, the voice alarm output unit and the analog quantity output unit through the CPU respectively. The special controller for the air source heat pump has the advantages that modularization integrated design is used, and accordingly cost and system space can be saved, and excellent on-site monitoring and data sharing can be achieved by the integrated free-port communication interface unit so that convenience is provided for system maintenance.

Description

1. Technical field [0001] The invention relates to a controller, in particular to a special controller for an air source heat pump. 2. Background technology [0002] At present, air source heat pump controllers often use 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 individual controllers can also meet the requirements requirements, but the expansion interface of the controller itself is not enough, and it is impossible to realize that the controller itself has multiple interfaces. 3. Contents of the invention [0003] In view of the deficiencies in the prior art above, the present invention provides a special controller for an air source heat pump, which can realize reliable operation, integrated control and multiple interfaces. [0004] The technical solution adopted by the present invention to solve the technical problem is...
