Abstract

This invention refers to an emulation method and apparatus of automatic instruction system, including a signal unit of picking and hanging machine for a signal of picking and hanging machine and a dialing signal of the automatic instruction system; an address comparing unit for sending the signal of picking and hanging machine to a central processor based on the result instruction of the signal comparison; a signal multiple connection unit for instruct an excitation feeder panel and the other plate of the automatic instruction system under the control of the central processor to act; a main control plate control unit for making all function plate of the automatic instruction system virtually exist and be controlled by the central processor of the main control plate, thereby making the main control plate in a normal working state; an audio frequency passage unit for accessing the audio frequency of the telephone machine to the connected excitation feeder plate passage. Using the technical solution of this invention uses a few of circuits to construct the device of off-line working of the main control plate (CPU plate), and uses simple hardware circuit to realize the emulated running of the automatic instruction system, with convenience, reliability and low cost.

Description

technical field [0001] The invention relates to the technical field of industrial wired communication, and more specifically, to a simulation method and device for an automatic command system. Background technique [0002] In outdoor industrial production sites or similar long-distance operation sites, automatic command systems are generally installed on site. These systems are important industrial wired communication devices for production commands and information release in the area. When this type of system is in use, the calling user uses the dialing method to realize automatic connection, realize individual or group loudspeaker calls, and the called end adopts high-power broadcast calls, and users can also conduct duplex calls through the end office to realize work instructions. of the release. The main functions of the system include call, call, group call, double group call, simultaneous call, silence detection, call timing and other functions. The system is mainly ...
