Description

INTEGRATION OF UNINTERRUPTED POWER SUPPLY WITH RASPBERRY PI Field of the Invention

The present invention relates to a device or system in which the Raspberry Pi supported by an uninterruptible power supply is integrated with the Cat-RPi UPS. The present invention particularly relates to an electronic device or system that is smaller than a normal computer integrated with an uninterrupted power supply (UPS) and in which the Cat-RPi UPS is integrated into the Raspberry Pi and that enables the system to be turned on and off without any external intervention in case of power interruption and activation.

State of the Art Uninterrupted power supplies are an electrical and electronic device that allows the energy to continue uninterruptedly for continuously operating systems. It generally has a system that protects sensitive devices affected by unstable electrical conditions in hospitals, production areas, computer systems, workplaces, or any system where similar electronic devices are used. This is a system that ensures energy continuity to devices in any power failure.

There are systems in the state of the art that contain some computer programs and microprocessors that preclude the system in which the system is turned on and off manually. However, as it is known, applications that run with microprocessors and computer programs are very costly in the market. Furthermore, these systems are separate systems that are connected with each other. In other words, they are not in the form of a single package or a single device. On the other hand, another disadvantage of programmable structures providing automatic use is that a failure in the microprocessor at any time will cause the whole system to become non functional. l In the state of the art, there are electronic devices called Raspberry Pi that are used in a customized manner in the market. Raspberry Pi is an electronic device that contains a computer that has many pins connected thereon and is customized by determining which pins will be used for what aims and by writing the appropriate codes and receiving appropriate outputs from these pins. These electronic devices can generally perform most of the processes of ordinary desktop or laptop computers, such as teaching programming to youngsters and children, managing electronic elements by compiling algorithms of IOT or robotic projects, testing simple software, and modeling etc. These Raspberry Pi devices in the state of the art are the systems in which they can naturally be integrated into an uninterrupted power supply like a computer. However, they are not in the form of a single package or device as mentioned above.

In the state of the art, uninterrupted power supplies are activated so as to ensure energy continuity in systems where uninterrupted power supplies are integrated. However, power outage in normal systems after a certain period of time, the Raspberry Pi's shutdown, and its restart in case of power availability is not automatic, but manual control is provided.

In the state of the art, uninterrupted power supplies operate when there is power outage so as to prevent the Raspberry Pi computer from collapsing. However, the operation regarding how long the Raspberry Pi computer will run so that it can resume its operations, when to restart after shutting down, are carried out manually.

In the state of the art, there are some systems that ensure automatic switching on and off, as well as manual operation in the systems where Raspberry Pi computer and uninterrupted power supplies are integrated. In the state of the art, Raspberry Pi device is damaged and leads to loss of data in case of sudden power failures that may occur during operation with Raspberry Pi and even the system used collapses and this means damages for the users.

Today, in applications where Raspberry Pi is integrated, different solutions have been searched so as to eliminate the problems experienced in sudden power outages. The use of programmable structures such as microprocessors so as to prevent electrical problems and to provide automatic control is one of them. Today, in another application where Raspberry Pi is integrated, control is provided manually when there is power outage and vice versa. In such a condition, commands are given to the system externally and completely manually. In case there will be sudden power outages, individuals shall know this condition in advance and record all documents related to the subject they are currently working on. Today, in case there is no advance warning, many people will not be able to predict when systemic interruptions may occur, and thus no sufficient and required precautions will be taken. As it is known, in a system in the state of the art where such a possible condition is experienced, no sufficient and necessary precautions can be taken, and the inevitable disadvantage of this system is waste of all the effort during the operation.

In the state of the art, no system has been provided wherein the Raspberry Pi and uninterrupted power supplies are integrated, which is in the form of a single package or device, is inexpensive and simultaneously does not contain microprocessors. In the state of the art, there is an American patent application numbered US2017064875. Said patent relates to the integration of a standard server cabinet, panel air conditioner, uninterrupted power supply and controls into a mobile system for use in modern data centers and other necessary facilities.

In the state of the art, there is a Russian patent application numbered RU2687898. Said invention relates to electrical measurement devices and is designed so as to obtain photoconductivity spectra of semiconductor samples.

In the international patent application numbered W02019001054 in the state of the art, Raspberry Pi series board forms a computer security power supply controller characterized by including a power supply control board. In said system, it is thought that it is insufficient to accommodate external manual control buttons so as to protect the computer in case of sudden interruptions, because it does not provide sufficient protection to the system. Although said system is used in the state of the art, it is thought that it cannot capture the advantages of the system according to the invention. In the state of the art, there is an American patent application numbered US2014159493. Said patent comprises a plurality of Uninterrupted Power Supply (UPS) systems, multiple UPS subsystems connected to a power connection cabinet; each multi-module UPS subsystem has a large number of UPS modules. The power connection cabinet contains one or more control devices, collectively referred to as PTC (power connection cabinet) controls. In said patent, PTC controls periodically determine a power outage message for each multi-module UPS subsystem and mention a process of transmitting the same to the relevant multi-module UPS subsystem.

As can be seen in the abovementioned patents and the state of the art, it is known that there are studies and products for the use of Raspberry Pi and uninterrupted power supply in different fields. However, no systems have been encountered in which Raspberry Pi and uninterrupted power supply are integrated together.

The system includes a device or system that can be integrated into any device in a single package. The system will be explained in this manner with the examples given below and the attached schematic figures. In this respect, it must be considered that these examples and figures shall not be binding.

The inventive system is a device or system that comprises the following; a power supply (6) that converts 24 volts into 5 volts and connects to the automation device, an uninterrupted power supply (7) that contains a battery in such a way that the system receiving 5 volts of energy from said power source can be safely switched on and off, a Raspberry Pi (2) that evaluates the information that receives the 5 volt voltage from said uninterrupted power supply and turns the system on and off, Cat- Rpi UPS (1) in connection with said Raspberry Pi (2) and said uninterrupted power supply (7). The inventive system comprises a screen (8) for at least one display and/or commands integrated into the system (as a whole, a single package) or connected to the system. The inventive system comprises the RPi 5 volt pins (4) which are on the Raspberry Pi (2), to which 5 volt energy is transferred to be used by the Raspberry Pi (2), the Rpi Run Pins (3) in connection with the Cat-Rpi UPS (1) and the RPi GPIO pins (5).

The inventive system is connected to any automation system, computer system or electronic device with a power supply (6). The power supply (6) is the energy connection section and the voltage regulator. The system works in a manner such that it theoretically lowers the voltage of 24 volts to 5 volts. Flowever, there will be variations in voltage in practice. For this reason, the voltage or energy values mentioned in this document shall not be limiting. The system is valid for different values. It is connected with the power supply (6), uninterrupted power supply (7) and Cat-RPiUPS (1). The power supply (6) transmits the 5 volt voltage energy to the uninterrupted power supply (7), also known as "UPS" in the market. The power supply (6) also transmits the power supply energy available information (a) to the Cat-RPi UPS (1).

In the inventive system, the uninterrupted power supply (7) is connected with the power supply (6), Raspberry Pi (2) and Cat-RPiUPS (1). The uninterrupted power supply (7) comprises at least one rechargeable battery, and the energy in said uninterrupted power supply (7) is for the system to be safely switched on and off rather than ensuring the continuity of the system. The uninterrupted power supply (7) receives the 5 volt energy from the power supply, charges it if necessary, and then transmits the 5 volt energy to the Raspberry (2). The uninterrupted power supply (7) transmits the uninterrupted power supply energy available information (b) to the Cat- RPiUPS (1). It also receives the uninterrupted power supply start command (f) and the uninterrupted power supply shutdown command (g) from the Cat-RPiUPS (1).

In the inventive system, Raspberry Pi (2) is an information processing unit or minicomputer. Raspberry Pi (2) Rpi is connected to the uninterrupted power supply (7) by 5 volt pins (4) and receives 5 volts energy from the uninterrupted power supply

(7). Said Raspberry Pi (2) Rpi GPIP pins (5) are connected with the Cat-RPi UPS (1) and it receives Cat-RPi UPS energy available information (e) from there and gives Raspberry Pi shutdown information (c) to there. The Raspberry Pi (2) also receives a restart command (d) by connecting with the Rpi Run Pins (3) and the Cat-RPi UPS (1 ).

In the inventive system, the Cat-RPi UPS (1) is an electronic control card that controls when the uninterrupted power supply (7) will be activated, Cat-RPi UPS (1) is connected with power supply (6), uninterrupted power supply (7) and Raspberry Pi (2). The Cat-RPi UPS (1) is connected with the power supply (6) and receives the power supply energy available information (a) from there. The Cat-RPi UPS (1) connects with the uninterrupted power supply (7) and receives the uninterrupted power supply energy available information (b) from there; it gives the uninterrupted power supply start command (f) and the uninterrupted power supply shutdown command (g). Cat-RPi UPS (1) is connected with Raspberry Pi (2) and Cat-RPi UPS gives energy available information (e) and restart command (d) and receives Raspberry Pi shutdown information (c) from there. In the inventive system, said power supply (6) comprises a power supply inlet (6a) and a power supply outlet (6b) having an inlet and an outlet feature; it is the source responsible for fulfilling the energy requirement of the system. It transforms the 24 volt energy coming from the power supply inlet (6a) on the power supply (6) into a 5 volt energy and transmits the same to the uninterrupted power source (7) through the power supply outlet (6b). At the same time, it is responsible for transmitting the power supply energy available information (a) and power supply no energy information (k) from the power supply outlet (6b) to the Cat-RPi UPS (1). Likewise, the uninterrupted power supply (7) also comprises an uninterrupted power supply inlet (7a) and an uninterrupted power supply outlet (7b). Here, the voltages as mentioned above are the required voltage values. There may be variations in voltage (e.g. +/- 1-20%) in practice.

The operating method of the inventive system with the structure mentioned above is as follows; the energy feeds the power supply (6) with 24 volts and the power supply reduces the energy it receives to 5 volts and transmits the same to the uninterrupted power supply (7). At the same time, the power supply transmits the energy available information (a) to the Cat-RPi UPS (1). Batteries are charged with the energy received by the uninterrupted power supply (7). At the same time, 5 volts of energy is transferred to Raspberry Pi (2). Also, in case there is energy in the uninterrupted power supply (7), the uninterrupted power supply energy information (b) is transmitted to the Cat-RPi UPS (1). When the 5 volt energy coming from the uninterrupted power supply (7) is received by the Raspberry Pi (2), a signal is sent to the Cat-RPi UPS (1) and the continuity of the system is ensured. The system is designed such that the Cat-RPi UPS (1) takes action when the power is cut off. The continuity of the system is ensured in this manner. In other words, if there is no energy in the power supply (6) (power is cut off), the power supply energy available information (a) to the Cat-RPi UPS (1) is also interrupted. In this case, the uninterrupted power supply (6) ensures the system to be shut down and then activated with its battery energy. Raspberry Pi (2) and Cat-RPi UPS (1) are operated by being powered from here. The Cat-RPi UPS (1) shuts down the Raspberry Pi (2) and activates the uninterrupted power supply (7). When the energy is received, the Cat-RPi UPS (1) restarts by transmitting the energy available information to the Raspberry Pi (2). Thus, the continuity of the system is ensured. Industrial Applicability of the Invention
