The present invention relates to the technical field of power supply, and more particularly, to an uninterruptible power system.
An uninterruptible power system (UPS) is used to provide backup power to required devices (e.g., computers, servers, or medical equipment) when AC mains fails, so that the devices can still in normal operation in this case.
However, the traditional uninterruptible power system does not provide intuitive information to the user in the event of a malfunction or an event that requires warning to the user, so that the user cannot quickly troubleshoot or respond. Therefore, how to solve the above problems has become an important issue.
An object of the present invention is to provide an uninterruptible power system, which can provide intuitive information to the user in the event of a malfunction or an event that requires warning to the user, so that the user can quickly troubleshoot or respond.
Another object of the present invention is to provide an operation method corresponding to the aforementioned uninterruptible power system.
To achieve the above object, the present invention provides an uninterruptible power system. The uninterruptible power system has a plurality of function blocks, and the function blocks form a topology structure of the uninterruptible power system. The uninterruptible power system comprises a sensing circuit and a control circuit. The sensing circuit is configured to sense the function blocks and to generate a sensing data accordingly. The control circuit is configured to determine, according to the sensing data, whether an event occurs in any of the function blocks. When the determination is yes, the control circuit generates an event code corresponding to the event and outputs a control command accordingly. The control command is used to control a display interface to display the event code, and is used to control the display interface to send a prompt message through a function block graphic symbol corresponding to the event code in the displayed topology structure.
To achieve the above another object, the present invention further provides an operation method of an uninterruptible power system, wherein the uninterruptible power system has a plurality of function blocks that form a topology structure of the uninterruptible power system. The operation method comprises the following steps: sensing the function blocks through a sensing circuit and generating a sensing data accordingly; determining whether an event occurs in any of the function blocks according to the sensing data; and when the determination is yes, enabling a control circuit to generate an event code corresponding to the event and accordingly output a control command for controlling a display interface to display the event code, and for controlling the display interface to send a prompt message through a function block graphic symbol corresponding to the event code in the displayed topology structure.
In order to make the above objects, technical features and gains after actual implementation more obvious and easy to understand, in the following, the preferred embodiments will be described with reference to the corresponding drawings and will be described in more detail
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:
The characteristics, contents, advantages and achieved effects of the present disclosure will become more fully understood from the detailed description given herein below and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present disclosure.
As required, detailed embodiments are disclosed herein. It must be understood that the disclosed embodiments are merely exemplary of and may be embodied in various and alternative forms, and combinations thereof. As used herein, the word “exemplary” is used expansively to refer to embodiments, that serve as illustrations, specimens, models, or patterns. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. In other instances, well-known components, systems, materials, or methods that are known to those having ordinary skill in the art have not been described in detail in order to avoid obscuring the present disclosure. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art.
The sensing circuit 128 is electrically coupled to the input unit 102, the first voltage conversion unit 108, the second voltage conversion unit 118, the output unit 120, and the battery 126, so as to measure these function blocks to obtain voltage information, current information, power information, temperature information, and other related information. The control circuit 130 is electrically coupled to the sensing circuit 128, so as to receive the sensing data outputted from the sensing circuit 128. In addition, the control circuit 130 is electrically coupled to the input unit 102, the first voltage conversion unit 108, the second voltage conversion unit 118, the output unit 120, the battery 126, and the display interface 140, so as to control their operations. For example, the control circuit 130 is configured to control the switch unit 106 to provide the output of the filtering unit 104 to the bypass path 132, or to provide the output of the filtering unit 104 to the input of the power factor correction circuit 110. The control circuit 130 is further configured to control the switch unit 122 to electrically couple the input of the filter unit 124 to the output of the DC-AC conversion circuit 118-1, or to electrically couple the input of the filter unit 124 to the bypass path 132, so as to supply power required by the backend devices through the output terminal 180 of the uninterruptible power system 100.
After measuring the function blocks and generating a sensing data accordingly, the control circuit 130 determines, according to the sensing data, whether an event occurs in any of the function blocks (i.e., an event of a malfunction or an event that requires warning to the user occurs). When the determination is yes, the control circuit 130 generates an event code corresponding to the event, and outputs a control command accordingly. The control command is used to control the display interface 140 to display the event code, and is used to control the display interface 140 to send a prompt message through a function block graphic symbol corresponding to the event code in the displayed topology structure.
The event code comprises at least two characters, and the characters may comprise letters, numbers, punctuation marks, other symbols, and the like. These characters are divided into two parts, and a part of the characters are used to represent an index.
After the control circuit 130 generates an event code corresponding to the event, the control circuit 130 searches out a function block corresponding to the index from a lookup table, and accordingly generates the control command. The lookup table records the correspondence between the function blocks and a plurality of different indexes, as shown in Table 1 below:
For the sake of brevity, the status numbers and their corresponding status information of index 1 to index 5 in Table 1 are omitted. In addition, the status numbers and their corresponding status information of index 0 are for illustrative purposes only and are not intended to limit the present invention. Certainly, the lookup table may record the information of the indexes and the function blocks only. In addition, the aforementioned lookup table is stored in an internal memory space of the control circuit 130, or stored in an external memory (not shown) electrically coupled to the control circuit 130.
Assume that the control circuit 130 generates an event code 01. The control circuit 130 determines that the index of the event code 01 is the number 0, searches out the battery which is the function block corresponding to the number 0 from the lookup table, and generates a control command accordingly. Then, the control circuit 130 outputs the control command to the display interface 140, so as to control the display interface 140 to display the event code 01, and control the display interface 140 to send a prompt message through the displayed battery graphic symbol 221. For example, the display interface 140 can, according to the aforementioned control command, send the prompt message by emitting light through the battery graphic symbol 221 or its surroundings, or by flashing the battery graphic symbol 221 or its surroundings. In this way, the uninterruptible power system 100 can provide intuitive information to the user in the event of a malfunction or an event that requires warning to the user, so that the user can quickly troubleshoot or respond.
The display interface 140 can be implemented by a liquid-crystal display (LCD), an electrophoretic display (EPD), a plasma display, or an organic light-emitting diode display (OLED display). In addition, the aforementioned LCD can be implemented by a graphic LCD, which comprises a patterned transparent film and a monochrome LCD. In this embodiment, the patterned transparent film has a plurality of graphic symbols to display related information of the uninterruptible power system 100. For example, it may have the graphic symbols as shown in
In addition, the uninterruptible power system 100 further comprises a communication interface 150, and the control circuit 130 further transmits the control command to a terminal (not shown) through the communication interface 150, so as to display the event code through the display interface of the terminal, and control the display interface to send a prompt message through a function block graphic symbol corresponding to the event code in the displayed topology structure. The communication interface 150 can be implemented by a Bluetooth communication module, a Wi-Fi (wireless fidelity) communication module, a network communication module, a USB (universal serial bus) communication module, an RS232 communication module, a CANbus (controller area network bus) communication module, or a Modbus communication module. The terminal comprises a desktop computer, a notebook computer, a tablet computer or a mobile phone. Certainly, in the case of having the communication interface 150, the uninterruptible power system 100 may not adopt the display interface 140.
It is worth mentioning that although the uninterruptible power system 100 adopts the filtering units 104 and 124, whether or not to adopt the two filtering units can be determined according to actual design requirements. In addition, the battery 126 and the bypass path 132 may be disposed inside or outside of the uninterruptible power system 100 depending on actual design requirements.
Although in the foregoing description, an on-line uninterruptible power system is taken as an example, this is not intended to limit the present invention, and those skilled in the art should know that an off-line uninterruptible power system and a line-interactive uninterruptible power system can also be operated as described above.
According to the description of the above embodiments, those of ordinary skill in the art should be able to summarize some basic operational steps of the uninterruptible power system according to the present invention, as shown in
In summary, by the above operation, the uninterruptible power system of the present invention can provide intuitive information to the user in the event of a malfunction or an event that requires warning to the user, so that the user can quickly troubleshoot or respond.
While the disclosure has been described by way of example and in terms of the preferred embodiments, it is to be understood that the disclosure is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
