- the purpose is to provide a master / slave configuration method for the board.
- Another object of the present invention is to provide a master / slave setting method of a redundant board that can quickly set a master / slave board through simple communication in a redundant board and a board thereof.
- a redundancy board includes first and second boards composed of redundancy, each of the first and second boards comprising: a power input unit to which an AC voltage is applied by initial booting; A voltage converter converting the applied AC voltage into a DC voltage; A communication unit transmitting a DC voltage value corresponding to the converted DC voltage to a counter board and receiving a DC voltage value of the counter board from the counter board; And when an initial boot signal and an AC voltage are applied from the outside, initialize the voltage converter, convert the DC voltage converted by the voltage converter to the DC voltage value, and compare DC voltage values of each board transmitted and received through the communication unit.

- the DC voltage value has a digital value composed of 1 and 0, and the communication unit transmits and receives the digital value of the DC voltage value to the counter board by 1 bit each other.
- the method for setting the master / slave board of the redundant board is the method for setting the master / slave board of the first and second boards composed of redundancy, wherein the boot signal and AC voltage are applied to the first and second boards.
- Input step of inputting When the AC voltage is input, the first and second boards initialize an internal voltage converter; A conversion step in which the first and second boards convert the input AC voltage into a DC voltage; A transmitting / receiving step in which the first and second boards respectively transmit their DC voltage values corresponding to the converted DC voltages to a counter board and receive DC voltage values of the counter boards from the counter board, respectively; And the first and second boards compare the DC voltage values of the first and second boards respectively transmitted and received to set the first and second boards as master or slave boards.

- the same software is mounted on the redundant board and the master / slave board can be set without additional configuration, the productivity of the product is increased and the possibility of malfunction is reduced.
- FIG. 1 is an exemplary view of a device to which a redundancy board according to an embodiment of the present invention is applied.
- FIG. 2 is a block diagram of a redundancy board according to an embodiment of the present invention.
- FIG. 3 is a flowchart illustrating a master / slave setting method of a redundant board according to an embodiment of the present invention.
- first, second, A, B, (a), and (b) may be used. These terms are only for distinguishing the component from other components, and the nature, order, or order of the component is not limited by the term.
- a device 10 to which a redundancy board 20 according to an embodiment of the present invention is applied includes a first board 21 and a second board 22 made of redundancy. Since the first board 21 and the second board 20 are configured with redundancy, the same configuration (hardware) and the same function (software and program) are mounted on each other.
- the device 10 may be configured in various forms. For example, it may be a control device that controls equipment or devices.
- the first board 21 and the second board 22 are boards provided in a general controller, and collectively refer to boards that perform various functions, such as a calculation board and a control board. .
- these boards 21 and 22 are used as a concept including devices such as a controller or a control module.
- a board duplicated by two boards 21 and 22 is shown as an example, but the present invention is not limited to this embodiment and may be configured by multiplexing two or more boards. That is, the method of setting the master / slave board according to the present invention can be equally applied to a multiplexed board. Therefore, in the present invention, for convenience of description, a duplicated board will be described.
- FIG. 2 is a block diagram of a redundancy board according to an embodiment of the present invention. As described above, since the redundant boards 21 and 22 each have the same configuration and function, only the first board 21 will be described below.
- the first board 21 includes a voltage input unit 211, a voltage conversion unit 212, a communication unit 213, and a control unit 214.
- the voltage input unit 211 is applied with a voltage when the board 21 is initially booted.
- This voltage is the starting voltage supplied from a separate power supply (for example, SMPS) when the device is booted in a state in which the power of the board 21 is turned off, specifically, the power of the device including the corresponding board 21 is turned off. Can be As such, when power is supplied to boot the device, power is also supplied to the board 21.
- the voltage input to the voltage input unit 211 may preferably be an alternating current (AC) voltage.
- the voltage converter 212 converts the voltage input to the voltage input unit 211 into a direct current (DC) voltage.
- the voltage converter 212 may use, for example, an ADC converter.
- the DC voltage converted by the voltage converter 212 is input to the controller 214, and the controller 214 stores a digital value (DC voltage value) of the DC voltage in an internal memory (not shown).
- the communication unit 213 transmits the DC voltage value stored as described above to the counter board 22 and receives the DC voltage value of the counter board 22 transmitted from the counter board 22.
- the transmission and reception of these DC voltage values are equally applied to both boards 21 and 22. That is, the second board 22 also transmits its DC voltage value to the first board 21 and, conversely, receives the DC voltage value of the first board 21 from the first board 21.
- the communication unit 213 transmits digital values through the differential communication lines 30 connected between the first and second boards 21 and 22.
- the differential communication line 30 supports the first board 21 and the second board 22 to transmit digital values to each other by 1 bit.
- the control unit 214 compares two DC voltage values transmitted and received through the communication unit 213 to set up a master / slave board. As a result of the comparison, a board having a relatively larger DC voltage value among the two DC voltage values is used as the master board. Set and set the board with a relatively smaller DC voltage value as the slave board.
- the setting of the master / slave board is to set the board to which a larger voltage is applied as the master board according to the size of the voltage applied during initial booting among the redundant first and second boards 21 and 22.
- the controller 214 receives the initial boot signal from an external CPU and initializes the voltage converter 212 when the initial boot signal is received.
- the first and second boards 21 and 22 perform this initialization. That is, when the initial boot signal is input from the external CPU to the first and second boards 21 and 22, each of the controllers 214 and 224 initializes its own voltage converter 212.222. This is for comparing the received DC voltage values with each other in the initialized state. At this time, since each control unit 214 and 224 of the two boards 21.22 can check both its DC voltage value and the DC voltage value of the counterpart board, it is possible to determine each one to be set as a master board or a slave board.
- the two boards 21 and 22 which are duplicated are substantially the same board. That is, it is the same board that has the same configuration and function and operates substantially the same. However, even if the two boards 21 and 22 are the same, the performance of the two boards 21 and 22 may be slightly different when used for a long period of time. At this time, in the present invention, after the power is simultaneously applied to the two first and second boards 21 and 22, the size of the applied voltage is checked with each other to set the board of the larger voltage as the master board. This makes it possible to quickly set a board with excellent performance as a master board.
- a preset board among the two boards may be set as a master board and another board as a slave board.
- FIG. 3 is a flowchart illustrating a master / slave setting method of a redundant board according to an embodiment of the present invention.
- the first and second boards 21 and 22 convert the voltage input to each to a DC voltage value corresponding to the digital value (S105), and transmit their DC voltage value to the counter board (S107). That is, each of the first and second boards 21 and 22 transmits its own DC voltage value to the counter board and receives the DC voltage value of the counter board from the counter board.
- the first and second boards 21 and 22 respectively compare two DC voltage values transmitted and received (S109). In this comparison, if its DC voltage value is greater than the DC voltage value of the opposite board (S111), it sets itself as the master board (S113), and, conversely, when it is smaller (S115), it sets itself as a slave board (S117).
- the preset board is set as the master board (S121), and the other board is set as the slave board (S123).
- each DC voltage value of a redundant board having the same configuration and function is compared to set a board having a larger DC voltage value as a master board and a relative board as a slave board.
- This method has the advantage of being able to quickly set up the master board in a simple way through communication between the boards.
