0 Introduction

    The application ofvoice analysis and synthesis carl be widely seen and make the work more cffectivesuch as stop voice direction of busfloor voice direction of

    elevator,price voice direction of tollgateAs to the industrial control systemthe unit

    of display and alarm is also indispensable beside the computer and related controlling interfaceTraditional display and alarm unitwhich is made up of flasher and

    buzzer,only awoke the operator of certain malfunctionThe device of voice direction

    and alarm not only awoke the operator the property and position of malfunction but also direct which measures should be taken to deal with the realfunctionSo the

    system call run under safe condition

    Basides the voice analysis and synthesisthe necessities of voice direction and

alarm devicein industrial control system also coverstrong^ill-jamming capability and

    stability,large memory to store the language library,intelligent device constituted by single chip microcomputerThe intelligent device not only can communicate with

    host to receive the controlling command but also link the voice in accord with the directions sentence

    ?er has all these The voice direction and alarm device introduced in this

    functions and Successfully applied in the oil sending out control system in the railway

    the device will voice to the operator the transportation in shanghai While controlling

    current working status and what should pay attention toaccording to command

    received from the host rOMRON PLC) When malfunction appearsit wih voice the

    property and position of malfunction to the operator ao({direct the operator which measure should be taken
