Abstract

The invention relates to a half-duplex communication circuit for an ecological house. The half-duplex communication circuit is formed by connecting an electric control board CN, four triodes (Q1-Q2), two diodes (D1, D2), nine resistors (R1-R9), a light-emitting diode (LED), an optical coupler O and two ports (P2.0, P2.1). The half-duplex communication circuit has the beneficial effects that the intellectualization degree of the ecological house is enhanced, and the operation is ensured to be more visual and convenient on the premise of ensuring the practicality, the safety and the reliability.

Description

technical field [0001] The invention relates to a half-duplex communication circuit, in particular to a half-duplex communication circuit for an ecological house. Background technique [0002] The design concept of the eco-house controller is to imitate the human body for a better life, and the rest environment emerges as the times require. It uses information electronics and other technologies to imitate the natural ecological environment, which can play the role of beauty, skin care, and health care. In this way, some existing practical technologies are integrated into a control system. The whole system is divided into three modules: the air conditioning control module, the central control block, and the human-computer interaction module. The three control modules realize mutual information through communication. transfer. [0003] But in the prior art, the half-duplex communication circuit system of the ecological house is not perfect. Contents of the invention [000...
