Description

[0001] APPARATUS FOR POWER SUPPLY BOARD TEST [0002]

The present invention relates to a power supply board test apparatus, and more particularly, to a power supply board test apparatus for testing whether a power supply board for supplying power to a computer is normal or defective.

Computer systems are becoming increasingly complex as a result of this increasing complexity. One result of increasing complexity is that it becomes more difficult to diagnose problems in computer systems when problems arise. It becomes more difficult to accurately manage computer systems in a manner that prevents problems in one part of the computer system from causing damage or problems in other parts of the computer system.

In particular, a power supply board that supplies power to a computer system plays an important role in providing stable power to the computer.

Therefore, it is important to test the power supply board to test whether the power terminal provided on the power supply board operates normally.

However, the conventional power supply board test apparatus only tests whether the voltage output value or the current output value on the power supply board is normal and only indicates whether the power supply board is normal or bad.

Therefore, the existing power supply board test apparatus can only determine whether the power supply board being tested is normal or bad, and it is not possible to identify the faulty output terminal when a fault occurs in the power supply board under test have.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and how to achieve them, will be apparent from the following detailed description of embodiments thereof taken in conjunction with the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the exemplary embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concept of the invention to those skilled in the art. And the present invention is only defined by the scope of the claims. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. It is to be understood that the present invention is not limited to the embodiments disclosed herein but may be embodied in many different forms and should not be construed as being limited to the exemplary embodiments set forth herein. It is provided to let you know. Wherein like reference numerals refer to like elements throughout.

1 is a configuration block diagram of a power supply board testing apparatus according to an embodiment of the present invention.

The power supply board test equipment of the present invention is a device for testing whether or not the power supply board, which is a device for supplying power to each component of a computer, operates normally.

 The functional configuration of the power supply board test apparatus determines the normal / abnormal state of the voltage / current value of the power supply board, and displays status information on the display window 400 of the LCD or the like. It also recognizes critical signals of the memory test equipment and determines whether the memory test equipment is faulty.

To this end, the power supply board testing apparatus may include a reference value database 300, a terminal measuring unit 100, a normality testing unit 200, and a display window 400. In addition, the measurement value output unit 500 and the input unit 600 may be further included.

The reference value database 300 is a database (DB) storing terminal reference voltages and reference currents. The measured value of the voltage and current measured at the terminal of the power supply board to be measured and the reference value to be compared are stored in the reference value database 300.

The reference value database 300 may be stored in an erasable programming ROM (EPROM) or the like, and may be stored in an F card (Compact Flash Card), an SD card (Secure Digital Card), an SM card A multi-media card), a memory stick, and the like, or may be provided in a separate device.

The terminal measuring unit 100 measures the voltage and the current output from the respective terminals of the power supply board, and outputs the measured voltage and the measured current. The current measurement of the terminal can be measured as the output value when the current is inputted through the current sensing resistor. Further, the voltage can be measured through the distribution resistance in the terminal measurement section 100.

For example, as shown in FIG. 2, when using the MAXIM's MAX4173TESA chipset for voltage current measurement, the current measurement is input to the RS + / RS- terminal of the MAX4173TESA through the current sensing resistor R1 The current value currently being used is output. In addition, the voltage may be output through a distribution resistor (R2 / R3).

When the measured voltage and the measured current measured at each terminal are compared with the reference voltage and the reference current assigned to the reference value database 300 and deviated from a predetermined error range, Outputs the terminal number and error value.

For example, when the error range is ± 5% and the reference voltage of the first terminal is 10 [V], the normal value is between 9 [V] and 11 [V] It can be judged that it is out of the error range.

Similarly, when the error range is ± 5% and the reference voltage of terminal 25 is 5 [V], the normal value is between 4.75 [V] and 5.25 [V] It can be judged that it has escaped.

For example, if the error range is ± 5% and the reference current of terminal 1 is 10 [mA], the normal value is 9 [ mA] to 11 [mA], and if it is out of the range, it can be judged that the error is out of the range.

In this way, when the measurement value out of the error range is generated, the normal state testing unit 200 outputs the terminal number and the error value of the terminal out of the error range. Where the error value is the difference between the reference voltage and the measured voltage or the difference between the reference voltage and the measured current.

For example, if the reference voltage of terminal 1 is 10 [V], the error value is +2 [V] when the terminal 1 is measured as 12 [V] and the reference voltage of terminal 25 is 5 [ V], when the terminal 25 is measured at 4.5 [V], the error value becomes -0.5 [V].

The display window 400 displays the terminal numbers and error values of the terminals out of the error range. The display window 400 may be implemented by various display means such as an LCD display window, an LED display window, and the like.

The input unit 600 is input interface means for receiving a set value from the user. The input unit 600 may include an input button for setting a reference voltage and a reference current stored in the reference value database 300 and a reset button for resetting the power supply board test apparatus to an initial value.

The input unit 600 may be implemented as a keypad or the like, but may also be implemented as a touch screen panel integrated with the display window 400. The touch screen panel is not only a screen display means but also an input means for sensing a touch by touch means such as a touch pen or a finger. In the case of a touch screen panel, the keyboard layout is overlapped with the screen of the touch screen panel in a graphic form. The position and transparency of the keyboard layout input window can be adjusted by the user. As a result, the administrator can input necessary characters or symbols by pressing the keyboard of the graphic keyboard.

The power supply board test apparatus may further include a measured value output unit 500 for outputting the measured voltage and current for each terminal as a voltage and a current of the same magnitude as the measured current and the measured current output from the terminal measuring unit 100. So that the current and voltage measured at the respective terminals of the power supply board are outputted from the measured value output unit 500 as the same size so that they can be utilized for testing in other test apparatuses.

Meanwhile, the power supply board of the present invention can be implemented so that the terminal is tested for each power supply block when the output value of each terminal is measured and tested for failure. In the case of a device such as a computer, a power supply board that supplies power to the computer is supplied with a different voltage and current for each power supply block that supplies power to each of the processor (CPU, memory, graphics card, etc.) Supply. Therefore, in the present invention, terminals are tested for each power supply block. Hereinafter, this will be described in detail with reference to FIG. 3 to FIG.

FIG. 3 is a block diagram of a power supply board testing apparatus for testing a power supply board according to an exemplary embodiment of the present invention. FIG. 4 is a front view of an actual product of the power supply board testing apparatus according to an embodiment of the present invention, 5 is a rear view of an actual product of the power supply board testing apparatus according to the embodiment of the present invention.

The reference value database 300 stores the reference voltage of the terminal and the reference current. In particular, the reference voltage and the reference current of the terminal may be stored for each power supply block.

For example, the reference voltage from 1 to 24 terminals belonging to the main power supply block is allocated and stored as 5 [V], and the reference of 24 terminals from the terminals 1 to 24 belonging to the main power supply block Voltage is allocated and stored as 10 [V], the reference voltage of 8 terminals from terminals 24 to 32 belonging to the RAM memory power supply block is allocated and stored as 5 [V], and the auxiliary power supply block The reference voltage of 8 terminals from terminal 32 to 40 belonging to the SATA power supply block is allocated and stored as 10 [V], and the reference voltage of 5 terminals from terminals 41 to 45 belonging to the SATA power supply block 6 [V] and stored.

In the case of a power supply board that supplies power to a computer, the power supply block includes a main power supply block for supplying power to the CPU (Central Processing Unit) and a RAM memory unit connected to the CPU An auxiliary power supply block for supplying power to the RAM memory power supply block and an auxiliary unit connected to the CPU, and a SATA power supply block for supplying power to the SATA unit, which is an interface unit for the hard disk, Lt; / RTI >

The terminal measuring unit 100 measures voltage and current output from each terminal for each power supply block provided on the power supply board, and outputs the measured voltage and the measured current.

The steady state test unit 200 compares the measured voltage and the measured current measured at the respective terminals of the power supply block with the reference voltage and the reference current assigned to the reference value database 300 and determines whether or not the measured voltage and the measured current deviate from a predetermined error range .

For example, when the error range is ± 5% and the reference voltage of each terminal of the main power supply block from terminals 1 to 24 is 10 [V], the normal value is 9 [V] 11 [V], and if it is out of this range, it can be judged that it is out of the error range.

Similarly, when the error range is ± 5% and the reference voltage of the RAM memory power supply block from terminals 25 to 32 is 5 [V], the normal value is 4.75 [V] to 5.25 [V] , And if it is out of the range, it can be judged that the error is out of the range.

The measurement current and the reference current can also be tested in the same manner. For example, if the error range is ± 5% and the reference current of each terminal of the main power supply block from terminals 1 to 24 is 10 mA ], The value judged as normal is a value between 9 [mA] and 11 [mA], and if it is out of this range, it can be judged that it is out of the error range.

As a result of the determination, the normal / non-normal test unit 200 outputs the terminal number, the block identification ID, and the error value of the terminal out of the error range when the error is out of the predetermined error range.

For example, when the block identification ID of the main power supply block is 'Ox0001', the block identification ID of the RAM memory power supply block is Ox0002, the block identification ID of the auxiliary power supply block is Ox0003, Assuming that the identification ID is 'Ox0004', when the error value of the voltage of the first terminal belonging to the main power supply block is +2 [V], it outputs the first terminal / Ox0001 / 5 [V].

The output information is provided and displayed on the display window 400, so that the user can precisely identify and cope with the power supply block, the terminal number, and the error value in which the failure occurs in the power supply board.

On the other hand, the power supply board test apparatus is connected to the monitoring server in the central control center through a serial cable, so that the terminal number, the block identification ID, the error value, and the power supply board test And a serial cable port for transmitting an identification ID of the device.

As shown in FIG. 6, a plurality of power supply board test apparatuses are provided, and a plurality of power supply boards can be tested at the same time. Each power supply board sends test results to the central monitoring server 10 at the central control center so that the central control center collectively collects the test results.

In addition, the central monitoring server 10 supplies a serial cable such as RS232, RS485, RS-422, and Ethernet (LAN) ports to the reference voltage, reference current and error range of the terminal for each power supply block test device To the serial cable port.

Therefore, the serial cable port provided in each power supply board test apparatus can receive the reference voltage, the reference current, and the error range of the terminal for each power supply block received from the central monitoring server 10.

Therefore, the power supply board test apparatus can be reset to the reference voltage, the reference current, and the error range received from the central monitoring server 10.
