Bus calling system of building construction elevator and method for controlling bus calling system

Abstract

The invention discloses a bus calling system of a building construction elevator and a method for controlling the bus calling system. By the aid of the bus calling system and the method, signal collision can be eliminated, and the bus calling system is high in interference resistance. The bus calling system of the building construction elevator comprises a plurality of calling units. The calling units are respectively mounted on a plurality of floors and are connected onto a bus in parallel, and the bus comprises a power line, a GND (ground) line and a signal line; the signal line is connected with a single chip microcomputer, and the single chip microcomputer is connected with call receivers of a main station by signal transmitters. The bus calling system of the building construction elevator and the method for controlling the bus calling system have the advantages that an integral calling procedure is controlled via the single chip microcomputer, signals can be automatically detected, signal conflict due to the fact that the multiple floors call simultaneously can be prevented, the bus calling system is high in interference resistance and reliable in performance, can be mounted easily and conveniently and can be used by a plurality of users simultaneously, a voice prompt effect can be realized, the bus calling system and the method can be widely used in building construction places such as hospitals, construction elevators and goods elevators, and the like.

Description

technical field [0001] The invention relates to a call system, in particular to a building construction elevator bus system call system and a control method thereof. Background technique [0002] There are two types of pagers: wired pagers and wireless pagers, and wireless pagers are the most widely used. According to product technology, wireless pagers can be divided into frequency modulation technology and amplitude modulation technology. The wireless pager using frequency modulation technology is more advanced, and the wireless pager using amplitude modulation technology is cheap but has many disadvantages. Pager is a system including software and hardware, which is widely used in catering, leisure, medical care, administrative office and other places. From the perspective of hardware components, there are FM pagers or AM pagers, control centers, digital information machines, monitoring system receivers, monitoring system software, signal boosters, number pickers, extern...

AI Technical Summary

Problems solved by technology

When multiple layers call at the same time, signal collision will inevitably occur, so that the call fails, resulting in low system efficiency and poor reliability
