ABSTRACT

PC-based motor control with SMS (Short Message Service) application is a system created to control the speed and direction of DC and AC motor by sending a specific SMS from mobile phone. The objective of this project is to bring conveniences to the motor user that can control the motor anywhere by using this SMS application. To achieve the objective, LabVIEW is used to design a virtual instrument for front panel. By using the design panel, the message send by the user can be display on the screen of PC for monitoring purpose. Upon to it, the speed and direction of AC motor and DC motor can be control by the design front panel with SMS notification. To implement this, GSM modem is used to connect LabVIEW front panel to receive the SMS from mobile phone. The utilization of GSM modem in this project as it ubiquity standard which enable subscribers to use their phones in many parts of the world, and make international roaming very common between mobile phone operators. This system is extremely handy and convenience to operate at any place by controlling the speed and direction of motor. AT command is used to control the function of the modem. Apart from that, data acquisition module (USB-6221) is used for real time monitoring and interfacing between hardware and software. Then, the physical value was converts to the readable data by front panel.

ABSTRAK

PC-based motor control with SMS (Short Message Service) application merupakan satu sistem yang dicipta untuk mengawal kelajuan dan arah memusing motor dengan penghantaran satu spesifikasi Short Message Service (SMS) melalui telefon bimbit. Objektif sistem ini adalah untuk membawa kemudahan kepada pengguna motor yang boleh mengawal motor di mana-mana tempat dengan mengguanakan applikasi SMS. Sebagai langkah untuk mencapai objektif projek, LabVIEW digunakan sebagai aturcara bergrafik untuk mencipta panel paparan peralatan maya. Oleh itu, mesej yang dihatar oleh pengguna dapat dipaparkan pada komputer untuk tujuan pengawasan. Setelah itu, kelajuan dan arah memusing motor dapat dikawal dengan menggunakan panel paparanLabVIEW melalui sistem SMS. Untuk melaksanakanya, satu GSM modem dihubungkan dengan panel paparan LabVIEW di mana ia boleh menerima SMS daripada satu rujukan nombor telefon bimbit. Projek ini memilih untuk menggunakan GSM modem kerana ia merupakan satu peralatan komunikasi yang mudah diperolehi di merata tempat. Ini adalah untuk membolehkan manusia berhubung antara satu sama lain dengan menggunakan telefon bimbit yang sedia ada di dunia ini. Sistem ini boleh dikawal dari jauh di mana manusia boleh mengawal kelajuan dan arah memusing motor tanpa menggunakan wayar. AT commands merupakan satu kod isyarat kawalan yang membolehkan modem tersebut berfungsi. Di samping itu, Data Acquisition Module (USB-6221) digunakan untuk pengawasan masa nyata dan ia merupakan pengantaramuka di antara perisian dan perkakasan supaya nilai-nilai fizikal yang diukur dapat ditukarkan ke bentuk data yang dapat dibaca melalui panel paparan.

1.1 Introduction PC-Based Motor Control System with SMS Application

At the end of August 2000, there were a total number of 6.3 million GSM (Global System for Mobile communications) users in the world. GSM technology makes it possible to wirelessly communicate, monitor and control nearly every aspect of a modern business and is regarded as the technology of the future. GSM monitoring and control is a new technology era [13].

SMS Control Systems (Pty) Ltd specializes in the application of the locally developed and operationally stable Cell secure and global remote GSM technologies which make it possible to monitor and control agricultural and industrial applications using SMS (Short Message Service). A potential user only need to use his cell phone

(18)

2 (any type or brand, only contract phones) in order to monitor and control agricultural and industrial applications.

The systems from SMS Control Systems which incorporate the GSM technology operate by sending and receiving SMS.

This developed system controls the PWM signal by using NI LabVIEW software and NI DAQ device (USB-6221) to monitor digitally and control the duty cycle as well as display the exact speed of the rotation. Besides, the GSM modem and mobile phone support the use of AT commands to send, receive and read SMS messages to monitor and control the DC and AC motor. The system can be used to monitor and control agricultural and industrial application using SMS (Short Message Service). Besides, this wireless system also can be monitoring and controls the motor in anytime, anywhere just by send a SMS. Furthermore, this wireless system can be save the cost for the wiring machine.

In order to improve current project, GSM modem will be implemented to send notification via SMS to control the speed and direction of DC and AC motor. This project is to develop a PC-based motor control by using SMS Short Message Service) application.

2.3 Introduction to SMS

SMS appeared on the wireless scene in 1991 in Europe. The European standard for digital wireless, now known as the Global System for Mobile Communications (GSM), included short messaging services from the outset.

In North America, SMS was made available initially on digital wireless networks built by early pioneers such as BellSouth Mobility, PrimeCo, and Nextel, among others. These digital wireless networks are based on GSM, code division multiple access

(24)

8 (CDMA), and time division multiple access (TDMA) standards.

Network consolidation from mergers and acquisitions has resulted in large wireless networks having nationwide or international coverage and sometimes supporting more than one wireless technology. These new classes of service provider’s demands network-grade products that can easily provide a uniform solution, enable ease of operation and administration, and accommodate existing subscriber capacity, message throughput, future growth, and services reliably. Short messaging service center (SMSC) solutions based on an intelligent network (IN) approach are well suited to satisfy these requirements, while adding all the benefits of IN implementations.

SMS provides a mechanism for transmitting short messages to and from wireless devices. The service makes use of an SMSC, which acts as a store-and-forward system for short messages. The wireless network provides the mechanisms required to find the destination station(s) and transports short messages between the SMSCs and wireless stations. In contrast to other existing text-message transmission services such as alphanumeric paging, the service elements are designed to provide guaranteed delivery of text messages to the destination. Additionally, SMS supports several input mechanisms that allow interconnection with different message sources and destinations.

2.3.1 SMS Applications

SMS was initially designed to support limited-size messages, mostly notifications and numeric or alphanumeric pages. While these applications are and will continue to be widely used, there are more recent niches that SMS still can exploit.

Short bursts of data are at the heart of many applications that were restricted to the world of data networks with fixed terminals attached to a local-area network (LAN) or wide-area network (WAN). However, many of these applications are better served if the data communication capabilities could be added to the mobility of the station. Thus,
