Special intelligent automatic control device for central air conditioning system

Abstract

The invention provides a special intelligent automatic control device for a central air conditioning system. The special intelligent automatic control device for the central air conditioning system consists of a digital quantity acquisition unit, a fault acquisition unit, an analog quantity acquisition unit, a temperature acquisition unit, a relay output unit, a fault output unit, a voice alarm output unit, an analog quantity output unit, a CPU (Central Processing Unit), a communication interface unit, a peripheral execution unit and an equipment information unit. The special intelligent automatic control device for the central air conditioning system is characterized in that the equipment information unit is connected to the CPU through the digital quantity acquisition unit, the fault acquisition unit, the analog quantity acquisition unit and the temperature acquisition unit, then the CPU is respectively connected to the relay output unit, the fault output unit, the voice alarm output unit and the analog quantity output unit, and finally the relay output unit, the fault output unit, the voice alarm output unit and the analog quantity output unit are gathered together and connected to the peripheral execution unit. The special intelligent automatic control device for the central air conditioning system has the beneficial effects that since the modular integrated design is adopted, the cost and the system space can be saved, the integrated voice alarm unit and the communication interface unit can realize good field monitoring and data sharing, and convenience is provided for system maintenance.

Description

1. Technical field [0001] The invention relates to an intelligent automatic control device, in particular to a special intelligent automatic control device for a central air-conditioning system. 2. Background technology [0002] At present, the central air-conditioning control system usually uses the PLC controllers of various manufacturers. 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 meet Preliminary requirements for 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 special intelligent automatic c...
