Intelligent cabinet control unit

Abstract

The invention relates to an intelligent cabinet control unit which comprises a control mainboard, a human-machine interaction module, an indoor temperature-humidity sensor and an outdoor temperature-humidity sensor, wherein the human-machine interaction module, the indoor temperature-humidity sensor and the outdoor temperature-humidity sensor are respectively electrically connected with the control mainboard, the control mainboard comprises a single-chip microcomputer, a power supply module, an alternating-current power supply detection module, a CPLD (Complex Programmable Logic Device), an A / D (Analog / Digital) conversion module, an intelligent control output module, an alarm output module, a storage module and a communication module with a plurality of communication interfaces; the single-chip microcomputer is respectively electrically connected with the alternating-current power supply detection module, the CPLD, the A / D conversion module and the storage module; the CPLD is respectively electrically connected with the intelligent control output module, the alarm output module and the communication module; and the indoor temperature-humidity sensor and the outdoor temperature-humidity sensor are respectively connected with the A / D conversion module. The intelligent cabinet control unit integrates core elements of the single-chip microcomputer and the CPLD, and has the advantages of high integration, powerful expansion function and simple circuit.

Description

technical field [0001] The invention relates to a control system, in particular to an intelligent cabinet control unit. Background technique [0002] With the rapid development and application of mobile communication technology and data communication network technology, telecom operators put forward higher and higher requirements for the reliability of various communication equipment. For unattended cabinets, changes in the environmental parameters of the computer room will directly affect the stable operation of communication equipment. For example, the temperature and humidity of the computer room are important parameters of the computer room environment. It is necessary to monitor the environmental indicators in real time and realize remote control or early warning according to changes in the environment. [0003] In the prior art, the cabinets are generally equipped with monitoring units, but the functions and structural components of the monitoring units produced by di...

AI Technical Summary

Problems solved by technology

[0005] (1) The monitoring unit used in the cabinet (room) is composed of a single-chip microcomputer as the core. There are many interface chips on the module, and the stability is relatively poor; the wiring is complicated and prone to errors;

[0006] (2) The single-chip microcomputer is the core control unit, and the functions of the pins of the single-chip microcomputer cannot be redistributed. It is difficult to expand and the configuration is not flexible.
