The present invention relates to an uninterruptible power system, especially a built-in uninterruptible power system.

With the development of science and technology, there are more and more types of devices that can be used for entertainment or as production tools in human society. Among them, personal electronic devices, such as computers, play a pivotal role.

The uninterruptible power supply can selectively filter the utility power according to different types (online uninterruptible power supply or offline uninterruptible power supply). After the power is supplied to the personal electronic device (online type first filters the mains before outputting the electricity to the personal electronic device), and after the mains supply is cut off, the battery included in the uninterruptible power system continues to supply power to the personal electronic device.

The connection between personal electronic devices and uninterruptible power systems is usually through external wires. However, for mini computers whose purpose is to reduce the size of the device as much as possible, connecting the uninterruptible power systems through external wires is not beneficial. Reduce the size of the device, which in turn leads to space consumption, and it is impossible to appropriately place the mini computer connected to the uninterruptible power system into a narrow gap in practice. Therefore, there is a need for an uninterruptible power system that can connect personal electronic devices with existing input and output interfaces without requiring additional wire connections.

The following examples further illustrate the viewpoints of the present invention in detail, but do not limit the scope of the present invention by any viewpoint.

Please refer to Figure 1. The uninterruptible power system according to an embodiment of the present invention can be implemented by the uninterruptible power system 100 in FIG. 1. In FIG. 1, the uninterruptible power system 100 includes a connection port 110, a battery 120, a charging path element 130, a discharging path element 140, and a control element 150. The connection port 110 has a plurality of metal pins, and the metal pins include a first voltage level power pin 111, a second voltage level power pin 112 and a data pin 113. The charging path element 130 forms a charging path between the first voltage level power pin 111 and the battery 120, and the discharging path element 140 forms a discharge path between the battery 120 and the first voltage level power pin 111. The control element 150 is connected to the connection port 110, the charging path element 130, and the discharging path element 140, respectively. The components shown in Figure 1 are to illustrate an embodiment of the present invention. The uninterrupted power system in practice can be extended in accordance with the spirit of the present invention. More components may be included as required, and the present invention is not limited by this. .

The port 110 may be a serial advanced technology attachment (SATA) port (the following is only referred to as a SATA port for ease of description), but the present invention is not limited to this. As long as a port has multiple power supply pins and not all power supply pins can transmit power when it is in operation, the new technology can be applied. The SATA port is usually included in a storage device, such as a hard disk, for transmitting power signals and data signals. The connection port 110 at this time includes a first voltage level power pin 111, a second voltage level power pin 112, and a data pin 113. Please refer to FIG. 2 at the same time. FIG. 2 is a schematic diagram of the distribution of power-related pins when the serial advanced technology is used to attach the ports to realize the port 110. Generally speaking, a SATA port can have different numbers of pins. In an embodiment of the present invention, there are 22 pins, which are 15-pin power transmission interface and 7-pin data transmission interface (not shown). Shows). Figure 3 shows the 15 pins. From top to bottom, there are 3 pins in a group, namely: +3.3VDC, COM, +5VDC, COM, and +12VDC, where COM can be grounded or Can be regarded as negative electrode. The SATA port can usually be used for 3.5-inch mechanical hard drives, 2.5-inch mechanical hard drives, or 2.5-inch solid state drives. When the motherboard's hard disk connection slot (also the SATA interface port) is connected to the SATA ports of different hard disks through the SATA cable, the motherboard can recognize different types of hard disks and their simultaneous or separate transports are different Power signals of large and small voltages (at least one of +3.3V, +5V, and +12V), for example, a 3.5-inch mechanical hard disk may require +12V to power the machine (such as disc operation, etc.), +5V and +3.3V For the main control circuit; 2.5-inch hard disks usually only need +5V and +3.3V, depending on the specifications, even only the smallest of the three voltages is +3.3V. In the case of a mini computer, because the mini computer is usually connected to a 2.5-inch hard drive due to its space design, when the mini computer is connected to a 2.5-inch hard drive through the SATA port, its motherboard can only supply power through the +3.3VDC pin , And does not supply power to the +12VDC and +5VDC pins. In detail, the functions of the present invention include connecting the uninterruptible power system with the hard disk connection slot of the motherboard of the mini computer. According to this, except for the power output of the SATA port for supplying power signals to the 2.5-inch hard disk In addition to the pins (for example, the 3.3VDC pin), the remaining power output pins in the SATA port can be used to supply power to the uninterruptible power system 100 according to an embodiment of the present invention. The uninterruptible power system 100 of an embodiment of the present invention receives and transmits power signals through the connection port 110. The first voltage level power pin 111 can be implemented by at least one of +12VDC and +5VDC pins, and the second voltage level The quasi-power pin 112 can be implemented as a +3.3VDC pin, and the data pin 113 can be implemented as a pin of an interface for data transmission. However, the present invention does not limit the supply to the first and second voltage level power pins The magnitude of the voltage of the power signal. In an embodiment of the present invention, the first voltage level power pin 111 is used to receive the power signal.

The battery 120 can be implemented as a lead-acid battery or a lithium battery in practice. In an embodiment of the present invention, it is preferable to implement the battery 120 as a super capacitor. The battery 120 is used to store the power signal transmitted from the first voltage level power pin 111 through the charging path. The battery 120 can also be a supply terminal of the power signal, and sends the power to the first voltage level power pin 111 through the discharge path.

The charging path element 130 can be used to control the power signal flowing into the battery 120. The charging path element 130 may be a charging integrated circuit (IC). In practice, after the power signal flows into the uninterruptible power system 100 from the first voltage level power pin 111, the charging path element 130 may allow the charging path to be turned on, so that the power signal flows into the battery 120 for charging. In addition, the charging path element 130 can perform more actions, such as stopping the charging of the battery 120, reducing the charging voltage, etc., which is not limited by the present invention.

The discharge path element 140 is used to control the power signal flowing out of the battery 120. In practice, the discharge path element 140 can be a switch. The discharge path element 140 can turn the discharge path on or off according to a switching signal. In practice, the discharge path can be preset to be in the off state. When the first voltage level power pin 111 receives the power signal, since the discharge path is open, the power signal can only circulate through the charging path. In addition, the discharge path element 140 can make the discharge path a path. When there is no external power supply or the power supply voltage is lower than the voltage of the power signal stored in the battery, the power signal is sent from the battery 120 to the first voltage level power pin 111 through the discharge path.

The control element 150 has a sensing pin, a charging control pin, and a discharge control pin. The sensing pin is connected to the first voltage level power pin 111, the charging control pin is connected to the charging path element 130, and the discharge control pin is The pin is connected to the discharge path element 140. In practice, the control element 150 may be a logic control integrated circuit (IC). In order to operate normally when the external power supply does not supply power to the first voltage level power pin 111, the control element 150 can be connected to the second voltage level power pin 112 to receive power for the operation of the control element 150. The control element 150 controls one of the charging path and the discharging path to be in an on state and the other in an off state according to the voltage sensed by the sensing pin. For example, the control element 150 can determine whether the voltage of the power signal received by the first voltage level power pin 111 falls within a charging value range, and control the charging path element 130 accordingly, and output a switch to the discharge path element 140 Signal. The charging value range can be preset to be the voltage value range of the power signal received through the first voltage level power pin 111 when the external power supply is normal. The control element 150 can perform the following actions after being judged: when the voltage value falls within the charging value range (that is, it is regarded as a normal use condition of external power supply), the control element 150 controls the charging path element 130 to allow the battery 120 to be charged, and Sending a switch signal of off to the discharge path element 140 to turn off the discharge path element 140 to form an open circuit in the discharge path; when the voltage value falls outside the charging value range (deemed as an abnormal external power supply), the external power supply may be If it stops due to different reasons, the control element 150 controls the charging path element 130 to stop charging the battery 120 at this time, so that no current flows into the battery 120, and at the same time outputs an on-off signal to the discharge path element 140 to make the discharge path element 140 Turning on causes the discharge path to form a path. In summary, when the external power supply is abnormal, the uninterruptible power system 100 of an embodiment of the present invention outputs the power signal stored in the battery 120 to the first voltage level power pin 111 through the conductive discharge path, for example as a mini computer Alternative power supply system.

Please refer to Figure 3. The mini computer can be connected to the uninterruptible power system 100 of an embodiment of the present invention through the hard disk connection slot of the motherboard. However, this will occupy the hard disk connection slot of the motherboard and the hard disk cannot be connected. Therefore, another embodiment of the present invention provides an uninterruptible power system 200 whose structure is roughly similar to that of the uninterruptible power system 100 in FIG. 1. Therefore, only similar components and their connections are shown in FIG. Those who have general knowledge in the relevant fields can find no difference after referring to the manual and the drawings, so the following text explains the differences. The difference between the two UPS systems 100 and 200 is that the UPS system 200 according to another embodiment of the present invention further includes a second connection port 260. The second connection port 260 includes a first voltage level power pin 261 and a second Voltage level power pin 262 and data pin 263. The data pin 263 can be directly connected to the data pin 213 of the connection port 210, and the second voltage level power pin 262 can be directly connected to the second voltage level power pin 212 of the connection port 210. The second connection port 260 can be connected to a storage device having a SATA interface connection portion, such as a 2.5-inch hard disk. The storage device can be powered through the second voltage level power pin 262 and interact with the outside through the data pin 263 to write data or transmit data. The uninterruptible power system 200 according to another embodiment of the present invention can connect the storage device through the second connection port 260 when the connection port 210 is connected to the outside. In this way, even if a personal device such as a mini computer is connected to the uninterruptible power system 200 through its hard disk connection slot, it can still be connected to the hard disk through its second port 260, and has the charging/powering function and the hard disk connection function. The two do not conflict with each other.

Please refer to Figure 4. FIG. 4 is a flowchart of an uninterruptible power system operation method according to an embodiment of the new type. The operation of the uninterruptible power system in an embodiment of the present invention is applicable to a motherboard and the uninterruptible power system described above that are connected to each other. Here, the uninterruptible power system 100 in FIG. 1 is taken as an example. Please refer to step S1, use the motherboard to determine whether the hard disk connection slot is electrically connected to the port 110, and after the motherboard determines that the hard disk connection slot is electrically connected to the port 110, set the first voltage level to the power pin 111 Electrically connected to the power input port of the motherboard. In detail, the judgment in step S1 can use the embedded chip usually set on the motherboard to send a signal to the hard disk connection slot, and the connected device can be identified after receiving an identification code sent back. Why. Accordingly, after the main board determines the connection port 110, the first voltage level power pin 111 is electrically connected to a power input port of the main board, so that the power input port outputs a power signal to the first voltage level power pin 111 .

Next, referring to step S2, the control element 150 is used to determine whether the voltage sensed by the sensing pin falls within the charging value range. If the voltage of the power signal falls within the charging value range, proceed to step S3; if it falls outside the charging value range, proceed to step S4.

In step S3, the control element 150 controls the charging path to be in the on state and the discharging path to be in the off state. At this time, the power signal can flow into the battery 120 from the first voltage level power pin 111 through the charging path to charge the battery 120. The charging path element 130 can modify the charging process, for example, it can adjust the magnitude of the voltage flowing in according to the state of charge (SOC) of the battery 120... This model does not limit this. After step S3 ends, return to step S2.

In step S4, the control element 150 controls the discharging path to be in the on state and the charging path to be in the off state. At this time, the power signal can flow from the battery 120 to the first voltage level power pin 111 through the discharge path, and then supply power to the motherboard. At the same time, by shutting off the charging path, the battery 120 can be protected to a certain extent, avoiding the possibility of the battery receiving an unstable voltage outside the charging range and causing improper loss. After step S4 ends, return to step S2.

In summary, the uninterruptible power system of an embodiment of the present invention receives the power signal through the first voltage level power pin in the connection port, and controls the charging path and discharge by the voltage sensed by the sensing pin of the control element One of the paths is in the on state and the other is in the off state. When the charging path is turned on, the power signal is transmitted to the battery through the charging path to charge the battery; and when the discharging path is turned on, the power signal stored by the battery is transmitted to the first voltage level power pin through the discharging path. In this way, external personal electronic devices, especially mini-computers, can be connected to the uninterruptible power system according to an embodiment of the present invention without additional wiring and additional ports.

Although the present invention is disclosed in the foregoing embodiments as above, it is not intended to limit the present invention. Anyone who is familiar with similar skills can make some changes and modifications without departing from the spirit and scope of this new model. Therefore, the scope of patent protection of this new model shall be subject to the scope of the patent application attached to this specification.
