Power Meter Billing Plus Load Control Using GSM System



Power meter billing plus load control using GSM (global system for mobile) system is a device, that not only calculate the monthly electric bill of consumer, as well as it also has a capability to control the load of user defined area. Beside this, the user can get their home load information and on or off their loads with the help of mobile phone. In other words, it has dual function capability. So many systems are available in market like this, but they do not have dual function capability as well as their cost is also so much high.



Beside this they are not so much efficient and reliable. We have designed this power meter billing plus load control using GSM system with the help of step down ac transformer, bridge rectifier, voltage regulator, LCD display, relay Driver, Max 232, energy meter, GSM modem and microcontroller 18F452 belongs to pic family. This power meter billing plus load control using GSM system controls the load of user defined area and calculate their monthly bill more efficiently and intelligently as compared to other systems. The block diagram of this power meter billing plus load control using GSM system with all their essential components is shown in figure 1

Working of Power Meter Billing Plus Load Control Using GSM System

This power meter billing plus load control using GSM system is directly connected with 230V ac. Because this system mostly consists of electronic components which are operated at 5 or 6V dc therefore 230v ac is stepped down to 9 or 6v ac with the help of ac transformer. Then these ac voltages are converted into dc with help of bridge rectifier and then these are regulated into 5V dc with the help of voltage regulated LM 7805. LCD display, Max232, relay driver and microcontroller are powered up with this voltage regulator. Microcontroller is the basically main intelligent controller of this system. It is programmed in c language with the help of mikro/c software and is interfaced with relay driver, energy meter, LCD display and GSM modem with the help of interfaced device MAX 232. Here for the test purpose we have used lamps at the output side of this power meter billing plus load control using GSM system.

For switching on or off the output loads, odd numbers such as 1,3,5 are configured for switching on and even numbers such as 2,4,6 are configured for switching off the output loads. These numbers are configured through microcontroller programming. For example, when the user sends the message after writing number 1or 3 then this message is received by microcontroller through GSM modem. Then microcontroller switch on that specific load. Similarly, for switching off that specific load the user will send the message after writing number 2 or 4 then that load would be switched off. During this the switching status will be also displaying on LCD display. Similarly, this power meter billing plus load control using GSM system also calculate the bill of this load and estimate the cost of this bill after every 10 pulses or unit. After estimating this cost, this system sends the intimation message to the user or consumer. So, the user can easily know the monthly bill and control billing cost by planning the related loads.

Applications and Advantages of Power Meter Billing Plus Load Control Using GSM System

  1. This power meter billing plus load control using GSM system could be installed within domestic and commercial building for power meter billing and load control.
  2. In conventional way for taking the energy meter reading, energy department sends their related person to take the energy meter reading which is so much time consuming and expensive way but by using this power meter billing plus load control using GSM system energy department can save its time and cost.
  3. This system is less costly, more reliable and more efficient as compared to other systems.
