Multifunctional intercommunication system for building engineering

Abstract

The invention relates to the technical field of intercommunication systems, in particular to a multifunctional intercommunication system for building engineering. The system comprises a circuit switching and standby power circuit. When ringing current is detected, a single chip microcomputer cuts off a telephone and an external line telephone circuit, thereby preventing the telephone from ringing. Information may be stored in the telephone, so power should be continuously provided for the telephone so as to ensure that information of the telephone will not be lost. Meanwhile, a power supply also provides power for reuse of a telephone keyboard set in the system. A call decoding circuit, a picking-up and hanging-up detection and DTMF decoding circuit and a speech storage and replay system are connected with the intercommunication system. A fingerprint recognition circuit is arranged on one side of a walkie-talkie and connected with a central processor. When a fingerprint is successfully recognized, the fingerprint recognition circuit will send a signal to the central processor and the central processor will control the telecommunication system to work, thereby achieving intercommunication processes. According to the invention, transmission is quite safe; the intercommunication system has the fingerprint recognition function, so remote intercommunication is achieved; the operation efficiency of the system is quite high; and the system is highly creative.

Description

technical field [0001] The invention relates to the technical field of intercom systems, in particular to a multifunctional intercom system for construction engineering. Background technique [0002] Construction engineering refers to the planning, survey, design and construction, completion and other technical work and the completed engineering entity and the installation project of the supporting lines, pipelines and equipment for new construction, reconstruction or expansion of houses, buildings and auxiliary structures and facilities. . It also refers to the construction of various houses and buildings, also known as construction workload. This part of the investment must be built and used, and can only be realized through construction activities. Among them, the construction projects of "houses and buildings" include factories, theaters, hotels, shops, schools, hospitals and residences, etc. The new construction, reconstruction or expansion must be constructed with ma...
