Intelligent temperature and humidity controller based on 3G network

Abstract

The invention discloses an intelligent temperature and humidity controller based on the 3G network. The controller comprises a temperature sensor and a humidity sensor, wherein the temperature sensor and the humidity sensor are mounted in a switchgear and connected with a single-chip microcomputer. The single-chip microcomputer is connected with a 3G network communication device, a heater, a fan, a relay, a memory, a wire break alarm output circuit, an LED display and a control button, and the heater and fan are connected with a power supply. The intelligent temperature and humidity controller displays temperature and humidity values via nixie tubes, the 3G network communication device capable of indicating and transmitting heater and sensor fault enables that remote monitoring, measurement, display, control and communication functions are integrated, the precision is high, and the measuring range is wide; and at the same time, the internal temperature and humidity of the switchgear are simultaneously monitored in real time, and the single-chip microcomputer is used for implementing control and storing and displaying data.

Description

technical field [0001] The invention belongs to the technical field of temperature and humidity controllers, in particular to an intelligent temperature and humidity controller based on a 3G network. Background technique [0002] The temperature and humidity controller products are mainly used for the adjustment and control of the internal temperature and humidity of equipment such as medium and high voltage switch cabinets, terminal boxes, ring network cabinets, and box transformers. It can effectively prevent equipment failure caused by low temperature and high temperature, as well as creepage and flashover accidents caused by moisture or condensation. [0003] The impact of temperature and humidity on electrical equipment is mainly reflected in the following aspects: [0004] Excessive humidity: reduce the insulation strength of electrical equipment; on the one hand, the humidity is too high, which reduces the insulation performance of the air. Many parts of the switchge...
