PC-BASED AUTOMATIC TIME MANAGER
ADEEB RAZA

M

any articles have been published in EFY for control ling devices through a PC’s parallel port or line printer (LPT) port. Here is another project for controlling a school bell or a scheduled shift-timing alarm of a factory automatically. The load connected to the output of the project can be an electric bell or a hooter. The timing can be programmed for every day schedule as per individual requirement. A Windows-based program developed in Microsoft Visual Basic pro-

gramming language is used for controlling an electric bell or hooter through an electromagnetic relay. It has been designed for Windows XP. The graphics have been included so that the master clock shows the real clock time on the PC’s screen. At the same time, it shows alarm clock timing for triggering the timer circuit for activating the bell or hooter. The alarm timings, ‘on’/’off’ controls and their activation sequence can be set by the user as per his requirement through 48 numbers of settings— that is, 24 settings for alarm time display on the screen and 24 for enabling or disabling the timer circuit. The alarm time as well as bell or hooter ‘on’/ ’off’ timer can be set by simple clicking the bigger rectangular box

and a small square box on the top of the rectangular box, respectively. The program output user interface is shown here in the screenshot.

Hardware interface
Fig. 1 shows the block diagram of the automatic time manager (ATM) and Fig. 2 shows the circuit diagram of the interfacing unit. Here, we are concerned with only two connections: pin 2 and a ground pin of the parallel port. Pin 2 corresponds to the first data bit ‘D0’ in 8-bit data bus of the parallel port. The whole unit is powered by a 6V DC regulated supply. LED1 is the power-’on’ indicator. IC MCT2E isolates the PC from the main interfacing unit in case any shortcircuit occurs. Thus, it acts as a safety device and protects the PC. IC LM555 (IC2) timer

    The purpose of the first application is to demonstrate that you can control many things from a distance instead of being at the actual location of the object. You can do this from a different location using the internet or onsite using the Local Area Network. This is done by connecting the object be it a nuclear power plant or a simple light bulb to a computer. Via the internet this can then be controlled from a far location. The equipment we used to perform this demonstration are a light, bell, relay, Data Acquisition device, and a computer that has the correct software installed. The local area network we set up on the main computer (the server) would bridge the way for operating the object from a distant location using the internet. We showed this by turning a light and a bell on and off using the computer directly connected to them (the server) and from another computer using the Internet.…

    Many electrical devices are “event driven”. An event simply means an input or output. For example, a computer is programmed to respond to a mouse click, or a keyboard press. When this event (input) happens, an action (output) will occur, for example opening of a window, or text appearing on a word processor.…

    The primarily responsibility is monitoring and controlling the numerous alarm "input" devices (manual and automatic detection modules) and then triggering the appropriate alarm "output" devices (horns, bells, warning lights, emergency telephone dialers, and building controls) (Gagnon, 2008). Control panels often run the gambit from single input and output units, to high-tech computer systems that can monitor numerous structures that spread out over campuses depending on requirements. The two most common control panel designs are conventional and addressable. Both of which are further detailed…
