FIELD OF INVENTION
This invention relates to a power backup system for an automatic teller machine (ATM).
BACKGROUND & PRIOR ART OF THE INVENTION
An inverter for supplying electric power during power interruption is widely utilized. In appliances, particularly in automatic teller machines, it is necessary to provide a backup power source, such as an inverter, in order to avoid a system's crash at the time of power failure. Therefore, the inverter backup systems have become the preferred choice for bank ATMs these days. The banks are contemplating deploying inverter backup systems for their ATMs and critical loads that may not be cost effectively powered by generators. The banks as a matter of urgency require reliable inverter backup solutions for their ATMs. No bank can afford to have ATMs that are out of service due to lack of backup systems when other ATMs are operational.
Reference may be made to the following prior arts:
Publication no GB1421163 is directed to an electric power supply for supplying an AC load from a DC source, of the kind comprising input terminals for connecting said DC source, output terminals for connecting said AC load, an inverter unit connected to receive DC power at the input terminals and to supply AC power at the output terminals. The invention also includes an AC load, for example an AC motor driven electrical appliance such as a cash register connected to the output terminals of a power supply. This invention doesn't have the wireless communication system and alerts service.

Publication no JP2004038865 provides a security function against a crime such as removal of an automatic teller machine itself by means of a simple structure. A control part supplies driving power to the ATM during its operation and supplies lower voltage power (DC 5V) when it is not operated. A current flowing through a load circuit of the ATM by supply of the low voltage power is monitored by means of a current monitoring part. If detection of the low voltage current is stopped, the control part determines break of a power source line, that is, determines that the ATM is removed and reports the fact to a management server in a security management center via a communication part. There is no power back up provision and wireless communication.
Publication no KR20040081989 provides a double uninterruptible power supply to allow for a smooth operation of operating system even in the occurrence of over discharge of a battery. This invention doesn't have the communication of the events.
Publication no JP10084677 discloses an uninterruptible power supply (UPS) always supplying power from the commercial power supply system which can concurrently supply an output on/off controllable by an external signal and an output normally carrying a current. This invention is not related to the security of the ATM.
Publication no JP4325841 provides an uninterruptible power supply which receives a busy signal from each automatic tellers machine when a customer is operating the automatic teller's machine or an automatic cash dispenser and which stops upon finish of operation of last customer. This invention is about the communication from ATM to the customer.

Reference may be made to an article by "Afam Nnaji, Bank ATM Inverter Backup Guide, June 23, 2008". The article describes an inverter which is coupled with a number of batteries connected to the ATM. This is basically a note counter with a small printer run by a microprocessor.
In light of the above, there is a need for a power backup system which can provide power backup to the automatic teller machine during power failure without stopping the automatic teller machine. Also, there is a requirement for a power backup system which is more efficient and logs the history of the automatic teller machine.
The present invention provides a power backup system to the automatic teller machine which operates at desired switching time. Further, the invention provides a power backup system which can operate multiple machines in a secure manner. Again, the invention saves power and appliances and thus is cost effective.

DETAIL DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS;
Referring to the fig. 1 the present invention discloses a power backup system 100 configured for machines such as but not limited to an automatic teller machine 10 comprises processing unit 101 comprising a memory unit 102 and control unit 102 A, converter 103, and switching devices 104. The processing unit 101 carries out the entire functions of the backup system. Additionally, the processing unit 101 senses the parameters such as but not limited to input voltage, output voltage, output current and battery voltage, battery current, ambient temperature and object detector's feedbacks. These different components are sensed by the sensing circuitry 105 which is connected between ATM 10 and control unit 102A of the backup system. The signals from this circuit 105 are sent to the processing unit 101, which acts according to the sensed signal. Storage devices 106 are also provided to store the charge so that backup power can be provided during failure.
The converter 103 as described herein is AC/DC and DC/AC converter.

The invention provides security for ATMs in which the power backup system detects the availability of the power in the ATM. In case, it is tried to switch off/ unplug the power or steal the machine i.e. the power is not delivered to the machine, the backup system detects it and sends SMS 8B Email, calls or raises alarm to the predefined persons or locations. The power backup system 100 comprises atleast two outputs high voltage power say of normal operating voltage of 120V and low voltage power for standby condition of machine. When the machine is in use the backup system provides high voltage power to the machine otherwise in standby position the backup system provides low voltage power. This switching is done by a switching device 104 such as relay or any solid state device. For preventing the stealing of machine or switching off the machine, the invention is also provided with a detector for detecting these conditions. The current flowing through a load circuit of the ATM is monitored by means of a current sensing circuit 105. In case, the current sensing circuit does not detect any current in the line, it determines break of a power source line, i.e. it determines that the ATM is removed/ shut down and sends SMS 8B Email, calls or raises alarm to the predefined persons or locations.
The backup system has multiple outputs as shown in figure 1B, so that it can operate multiple ATMs simultaneously. Multiple ATM machines are connected with their respective sensing circuits and switching devices which are controlled or monitored by a common backup system.
The present invention uses a wired/wireless protocol provided with two way communication system 107. The user can give predefined instructions to the system 100 and the system 100 can also give predefined responses. It provides connectivity of the power backup system 100 to the internet with or without a computer. Using this, the

user can monitor & control the machine from a remote location even by using hand held device. Because of the wired/wireless protocol provided with two way communication system 105 the power backup system 100 can receive commands from a remote location and then transmit it to the automatic teller machine 10 such as but not limited to shut down the machine etc. If the automatic teller machine 10 runs for a longer time or a user uses the machine for a number of times, power backup system 100 has the options to shut down the machine 10 and raises an alarm as per the user's requirement. The inverter switches the battery for backup with desired switching time for ATMs. Due to the suitable switching time, the inverter provides a secure dispensing service.
The backup system 100 logs the history of the counting machine such as how much cash has been dispensed, number of times card inserted, number of times power failure occurred, number of times the cash has been dispensed, number of times the machine was shut down, time duration for shut down etc. This information is stored in the memory 102 built in the power backup system 100.
Figure 2 shows the flowchart according to the present invention. When power backup system is ON, the parameters such as time or any other parameter as per the requirement are set initially during installation. During installation, user needs to switch ON the power back up system and ATM by entering the email ID or phone number or web location to which the alerts should be sent. This is carried out through the display on the power back up device or remotely by the wireless device configured to the power back up system. Once it is installed it is ready for the functions.
If during the operation of the ATM, the ATM is running without interruption for more than a predefined time or the sensing circuitry

detects no current flowing through the back up system, the processing unit sends the alert message to the preconfigured email or phone number or web location considering it as a special condition.
The memory unit sends the event log such as but not limited to the Number of times the card was inserted, Number of times of power failure, Number of times the cash has been dispensed, Number of times and duration when the machine was shut down, to the configured location by request.
If there is no interruption, the ATM process goes ON and backup supply is provided by the system and the ATM runs on the same voltage supply. If the ATM needs low voltage supply, the processing unit sends the signal to the switching device so that the ATM is powered with low voltage supply,
Thus, the system provides low cost technology that can be widely deployed in the wired/wireless control and monitoring of the ATMs.
It is to be understood that the above-described embodiments are illustrative of only a few of the many possible specific embodiments, which can represent applications of the principles of the invention. However, numerous and varied other arrangements can be readily devised in accordance with these principles by those skilled in the art without departing from the spirit and scope of the invention.
