Design And Simulate A Computer Three Way Intercom System


Communication has bee a growing area in modern computing through the use of network and efforts have been made towards evolving an efficient and quickest way of communication.

The essence of computer in this civilized and computer age can be over emphasized. it use is felt in the aviation where rather is extensively used. In military, communication services such as radio message and signaling are being employed. It is also being made use of in space travel; navigation and marine services, radio and television broadcast make use of communication system and also line-to-line communication.

For the purpose of this project three -way computer intercom system in a hotel to be precise, we would not over emphasize on the need of such communication system in a hotel room/environment.

Chapter One


Information and instructions are usually conveyed wither directly or indirectly by the chief executive or Via his messenger. However, this method of information dissemination has its demerits. It wastes time and sometimes, the messenger conveys incorrect information. To reduce the time wasting experienced in the above method, one then appreciates the need to design and simulate a system that will help to eliminate the loss of time during information delivery.

This transmission is known as inter communication usually abbreviated as โ€œ intercomโ€ . this refers to communication by means of transmission medium between various individual situated at comparatively distance within a certain premises. These locations are called stations and this gave birth to the topic simulate a computer three way intercom system. This system. This system provides at lest three way communication via the computer network stations controlled by spftware. Hence the function of the of communication supervised by a package, to interface the computer//stations as intercom sets, enabling orders and instructions to be received and that they are clearly understood and fruitfully executed.

These intercom system are used in offices, factories workshop and for the purpose of this project, in hotel as to eliminate the necessity of conveying message through messengers from one guest/attendant to another ir vise vaster. These improve work and enable quick decision by the supervisory staff/executive.

The system, make use of these equipment to achieve its goals.

1.1 Statement Of The Problem

the main function of this study is to over come the problems encountered in manual organizational communication. From the interviews with some organizations, it was noted that the manual methods of information dissemination in an organization pose some problems Vis.

  1. Time wasting
  2. Incorrect information
  3. Poor security

Time Wasting:

Consider the time interval between the moment the chief executive calls the messenger to this officer for a message and the time the message goes and come back for the feed back. From this, the fact that a lot of time has been wasted is an axiom and can consequently lead to delay in some works.

Incorrect Information:

At times message can be forgotten, misunderstood or misinterpreted by the messenger or supervisors. This can case a very big havoc in the organization.

Poor Security:

Some message may be vital and restricted to a group of people in the organization; this information need not be discussed outside the group for which it is interned. By the manual information method such information leaks.

1.2 Purpose Of The Study

The purpose of this project is to simulate a software package for the three-way computer intercom systems in order eradicate some problems encountered by the use of manual operation methods.

1.3 Significance Of The Study

The aim of the study lies on the fact that the manual system of organization communication is faced with numerous problems. These problems tend to cause distortion in the effective and efficient information flow. The main objectives of this study are:

  1. To discover the problems associated with the manual method of organizational communication.
  2. Modify the existing methods of information dissemination in an organization.
  3. To develop an efficient computer based intercom system. Study however, if this new system is implemented, it will enhance efficiency in the information dissemination in an organization.

1.4 Scope Of The Study

This study was carried out using three-way intercom system. This means that it only lovers three department in an organization.

1.5 Limitation

during the study the authors encountered a lot of constraints that consequently poses sort of inconvenience on the authors during their project work, one of such limitation search effectively. Unavailability of the materials for the project has equally contributed to a problem during the study, also finance, was another area of limitation because the authors went through hell, while sourcing for money to carry out this work.

1.6 Definitions Of Terms

1. Communication:

It is a process whereby the encoder and decoder exchange hydration so that makes meaning and understanding between them.

2. Computer:

An electronic device that accepts information, process, stores and gives output at a high speed.

3. Loudspeaker:

This is an electrical device that converts electrical impulse into sound energy.

4. Microphone:

It is an electrical device that converts sound to electrical energy.

Chapter Seven

7.0 Recommendations

Due to increase in technology in this modern generation an origination an organization need not waste any time in careering out their functions with manual information dissemination in an organization, the authors strongly recommend the installation and use of this project- three โ€“way-computer-intercom-system in organization because it will go along way in alleviating.

The problems we encounter with the manual type.

There should be a routines check and cleaning of the system to maintain its efficiency and life span. Also effort should be made to provide a constant power supply to then.

The project is open for further development by fuster work if the need arises and new innovation emanates. And there should be adequate funding in order to achieve a competitive and favourable implementation of this project

7.1 Conclusion

The main aim of simulating a three way computer intercom system has been achieved after a through research and study towards the development and justification of this project, the authors found out that the system is reliable and also kedules human labour unlike the manual information dissemination. The system will operate optimally when operated within the liarit of safety and temperature within 0oC – 600C and normal atmospheric pressure.
