Operation flowchart of a remote control unit according to an embodiment of the present invention.

In the embodiment of the present invention, the communication operation of the control unit for controlling the operation of the uninterruptible power supply will be described.

Looking at the configuration of the present invention with reference to Figure 1, it uses an 80535 (siemens) with five ports and built-in A / D converter, uninterruptible power supply according to the user's control operation and the operation state of the uninterruptible power supply Main control unit that transmits / receives the corresponding information using the first to sixth communication lines A1 to A6 connected to a control signal for controlling the supply device or information corresponding to an operation state through a set communication method. (1); The controller may be connected to the main controller 1 to display an operation state of the uninterruptible power supply device, a selection type of an operation selected by a user, and corresponding data according to a control signal output from the main controller 1. 1 information display section 11; The first switch unit 12 is connected to the main control unit 1 and changes the operation state of the uninterruptible power supply by changing the operation state according to the user's selection operation and to change the position of the operation key. )Wow; An operation of the main control unit 1 using 80535 is performed by receiving respective information input from the main control unit 1 through the first to sixth communication lines A1 to A6 connected to the main control unit 1. A remote control unit 2 for determining a state and an error occurrence state or an operation state of the first switch 12 and outputting a control signal capable of determining the operation state of the main control unit 1; Connected to the remote control unit 2, the corresponding information output through the remote control unit 2 via the first to sixth communication lines A1 to A6 is displayed, and corresponds to the operation of the remote control unit 2. A second information display unit 21 for displaying information; Connected to the remote control unit 1, each operation state is changed according to the user's selection operation so that the remote control unit 2 controls the operation of the main control unit 1 to control the operation of the uninterruptible power supply It consists of a switch unit (12).

The first switch unit 12 has an operation control switch S11 in which one terminal is grounded and the other terminal is connected to the main control unit 1, and one terminal is grounded and the other terminal is connected to the main control unit 1. Connected to the first to fifth operation selection switches S111 to S115, one terminal of which is grounded, the other terminal of which is connected to the main control unit 1, and a number increasing switch S121, and one terminal of which is grounded The other terminal consists of a number reduction switch (S122) connected to the main control unit (1).

The second switch unit 22 has an operation control switch S21 in which one terminal is grounded and the other terminal is connected to the remote control unit 2, and one terminal is grounded and the other terminal is connected to the remote control unit 2. Connected to the first to fifth operation selection switches S211 to S215, one terminal is grounded, the other terminal is connected to the remote control unit 2, the number increasing switch S221, and one terminal is grounded. The other terminal is composed of a number reduction switch S222 connected to the remote control unit 2.

The operation of the present invention made as described above is as follows.

First, when the operation of the main control unit 1 starts (10), the main control unit 1 initializes the state of the main control unit 1 (20), and outputs the initial information to the first information display unit 11 Execute the action.

Therefore, the main control unit 1 calls the value of the sub function disxy (str) indicating the type of information and the value of the sub function ad-conv (str) indicating the data corresponding to the type of information. Accordingly, the desired information type and data are output to the first information display section 11 (30).

When the main control unit 1 operates for the first time, the first information display unit 11 displays an initial subfunction such that data of information corresponding to the middle part number among serial numbers indicating various types of information can be output. The value of (disxy (str), ad-conv (str)) is set.

Therefore, after the main control unit 1 operates to output the type of information and the corresponding data to the first information display unit 11, the main control unit 1 is a first switch unit for controlling the operation of the uninterruptible power supply. The input state of the operation control switch S11 of (12) is sensed to determine whether an operation control signal is input (40).

Therefore, when a control signal for controlling the operation of the uninterruptible power supply is input by the operation of the operation control switch S11 of the first switch unit 12, the main control unit 1 executes a sub function (disp-key ()). To determine which switch is selected by the user among the first to fifth operation selection switches S111 to S115 of the first switch unit 12 using the function value of the sub-function disp-key (). In operation 50, the control operation corresponding to the selected operation switch selection switch S111 to S115 is performed.

The sub function (disp-key ()) is used to selectively execute various operations of the uninterruptible power supply. When the sub function (disp-key ()) is called by the operation of the main controller 1, 1 As the signal output to the information display unit 11, the word "Press any key" is output.

In addition, among the first to fifth operation selection switches S111 to S115 of the first switch unit 12 connected to the main control unit 1, a corresponding switch is selected to perform a desired operation, and a sub function ( The function value of disp-key () has the value corresponding to the optional switch.

Therefore, the main controller 1 reads the function value of the sub function disp-key () and performs an operation corresponding to the selected switch.

In the embodiment of the present invention, a plurality of operation selection switches S111 to S115 for controlling the operation of the uninterruptible power supply are configured to overcharge the voltage of the battery to be used and to convert the applied AC voltage into DC. Selects an operation of charging the DC voltage with the battery and simultaneously inputting the DC voltage to the inverter, and allowing the corresponding AC voltage to be output from the inverter as the DC-converted voltage is applied to the input terminal of the inverter. Can be.

In order for the uninterruptible power supply to function properly, when the uninterruptible power supply is in a normal state, a corresponding voltage is supplied to the inverter so that it can operate normally. When the uninterruptible power supply is abnormal, the power applied to the output is The operation for stopping the operation of the warning device for notifying the failure of the uninterruptible power supply by checking whether the switching operation to be applied by bypass is normally performed and repeating three or more times, and the state described above. In the event of a failure of the uninterruptible power supply, the operation of the warning device may be selected to stop the operation of the warning device and to take necessary measures.

After any one of the first to fifth operation selection switches (S111 to S115) of the first switch unit 12 for controlling the above operation is selected to perform the corresponding operation by the main control unit 1 Or the main control unit 1 when the operation control signal is not input, the number indicating the type of information output to the first information display unit 11 by the operation of the number increasing switch S121 of the first switch unit 12. If the number is increased (60), and the address increase switch (S121) is not operated and the number indicating the type of information does not increase, the main control unit 1 switches the number reduction switch of the first switch unit 12. In operation S122, it is determined whether the number indicating the type of information is reduced (80).

However, when no switch is selected among the operation selection switches S111 to S115 after the operation control signal is input, the main controller 1 continuously outputs the word “Press any key” through the first information display unit 11. do.

When the value of the variable Str is increased by the operation of the number increasing switch S121 of the first switch unit 12, the main control unit 1 determines that the number indicating the type of information is increased and the sub function (disxy ( str)) and (ad-conv (str)), and after outputting the corresponding information type and data value to the first information display unit 1 (70), it is determined whether the number indicating the type of information has decreased. (80).

When the value of the variable Str is decreased, the main controller 1 determines that the number indicating the type of information is reduced and uses the sub function disxy (str) or ad-conv (str) to determine the corresponding information. After outputting the type and data value to the first information display unit 11 (90), it is determined whether a power source capable of operating the remote control unit 2 is normally applied (100).

Therefore, when the number indicating the type of information is increased or decreased by the user, the main control unit 1 uses the function value of the sub function disxy (str) or ad-conv (str) that is changed by the user's operation. The data can be output to the information display unit 11 of the main control unit 1.

Table 1 below shows the relationship between the type of information and the display form according to the variable value Str of the subfunction disxy (str).

TABLE 1

In order for the main controller 1 to determine that power is supplied to the remote controller 2, the main controller 1 is connected to the same port of the main controller 1 and the remote controller 2. Signal states of the communication line A5 and the sixth communication line A6 are used.

Therefore, when the values of the fifth and sixth communication lines A5 and A6 are all at a high level, the main controller 1 determines that power is applied to the remote controller 2, and the fifth and sixth communication lines A5. When all values of A6 are maintained at the low level, it is determined that power is not applied to the remote control unit 2.

If it is determined that the necessary power is supplied to the remote control unit 2, the main control unit 2 maintains the signal states of the fifth and sixth communication lines A5 and A6 in a high state so as to provide a necessary signal. To be transmitted.

Therefore, when it is not operating because it is not applied to the remote control unit 2, the main control unit 1 outputs the type and data of the corresponding information to the first information display unit 11 (30), and the remote control unit 2 When the power is applied, the main controller 1 determines whether the operation state of the main control unit 1 is variable or the state of an error occurring during the operation is changed (110).

However, when the operation state or the error state of the main control unit 1 does not vary, the main control unit 1 determines whether the interrupt request signal has been received through the fourth communication line A4 (130).

Therefore, if the number indicating the rectification of the information is variable and the type of information or data value is output, the operation state of the uninterruptible power supply is changed, or when a new error occurs during operation, the main control unit 1 is the same. The subfunction calls a subfunction (disxy (str)) to allow the user to know the type of information and a subfunction (ad-conv (str)) to allow the user to know the corresponding data value according to the selected information. Data corresponding to (disxy (str)) and ad-conv (str) is transmitted to the remote control unit 2.

Therefore, it can be seen that the operation state of the main control unit 1 in the remote control unit 2 has changed.

When communicating the corresponding information from the main control unit 1 to the remote control unit 2, the main control unit 1 firstly controls the remote control unit 2 through the third communication line A3 for transmitting / receiving an interrupt request signal. The interrupt request signal is sent to the remote control unit 2 so that when the remote control unit 2 is processing any operation, the processing operation can be paused and the data transmitted from the main control unit 1 can be received.

In addition, the remote control unit 2 receiving the interrupt request signal outputs a response signal to the main control unit 1 through the fourth communication line A4 in order to receive data transmitted from the main control unit 1.

Therefore, the main control unit 1 receiving the response signal transmits the corresponding data to the remote control unit 2 via the first communication line A1 which is the first transmission / reception line.

The remote control unit 2 accurately grasps the type of data transmitted from the main control unit 1 so as to know in advance the type of the received data.

Accordingly, the main controller 1 outputs a signal indicating the type of data transmitted through the fifth and sixth communication lines A5 and A6 before transmitting the data to be transmitted.

The types of transmission data according to the signal values of the fifth communication line A5 and the sixth communication line A6 are shown in Table 2.

TABLE 2

Therefore, when data corresponding to the remote control unit 2 is transmitted through the above process, the main control unit 1 determines whether an interrupt request signal has been received (130).

Therefore, when the interrupt request signal is not received, the main control unit 1 outputs the type and data of the corresponding information to the first information display unit 11 (30).

However, when the interrupt request signal is received, the main control unit 1 outputs a response signal to the remote control unit 2 through the fourth communication line A4, and then receives data transmitted from the remote control unit 2 to receive the received data. The operation is performed according to the contents (140).

Therefore, the main control unit 1 operates through the above method, and transmits data corresponding to the remote control unit 2 so that the remote control unit 2 can grasp the operation state of the main control unit 1, and the main control unit The operation of (1) can be controlled by the remote control unit 2.

The operation of the remote control unit 2 will now be described with reference to the third (a) and the third (b) diagrams.

First, the state of the remote control unit 2 is initialized (1100), and the remote control unit 2 determines whether an interrupt request signal is received from the main control unit 1 (1200).

When the interrupt request signal is received from the main control unit 1, the remote control unit 2 may change the operation state or the like of the main control unit 1 so that the main control unit 1 transmits corresponding data to the remote control unit 2. Judging by the operation, the remote control unit 2 transmits a response signal to the main control unit 1 through the fourth communication line A4.

When the main control unit 1 receives the response signal, the remote control unit first transmits a signal corresponding to the type of data transmitted as shown in Table 2 through the fifth and sixth communication lines A5 and A6 before the data signal. 2), the remote controller 2 receives the signals received through the fifth and sixth communication lines A5 and A6 first, and then receives the data transmitted from the main controller 1 (1300). .

However, when the interrupt request signal is not received from the main control unit 1, the remote control unit 2 determines whether the type number of the information for changing the type of information output through the second information display unit 21 has increased. (2600).

Therefore, when the remote control unit 2 receives the data transmitted from the main control unit 1, the remote control unit 2 has a value of "1" for all of the signals received through the fifth and sixth communication lines A5 and A6. It is determined whether the value of (1400).

Therefore, when the values of the fifth and sixth communication lines A5 and A6 of the remote control unit 2 are all "1", the remote control unit 2 determines the actual value corresponding to the type of data to be transmitted. Judging by the data for.

Therefore, the remote control unit 2 receives sub-functions (disxy (str) indicating the type of information of the main control unit 1 in order to receive the measured value of the operation of the main control unit 1 and output the corresponding data. In step 1500, it is determined whether the data value corresponding to 1) is one of 0 to 2 or 6 to 11.

Therefore, when one of the values corresponds to any one of the above values, the remote controller 2 outputs the measured value according to the type of the selected information received from the main controller 1 to the second information display unit 21. The data determined by the function value of -conv (str)) is calculated according to the following formula (1) (1600).

Data value × (220/204) (1)

Therefore, after outputting the value calculated according to the above formula (1) to the second information display unit 21 of the remote controller 2 (1700), it is determined whether the number indicating the type of information has increased (2600).

However, when the value corresponding to the sub function disxy (str) of the main control unit 1 is not included in 0 to 2 or is not one of 6 to 11, the value corresponding to the sub function disxy (str) is In operation 1800, the remote controller 2 determines the received data value determined by the function value of the sub-function (ad-conv (str)) according to the following expression (2). In operation 1700, the measured value displayed on the second information display unit 21 is output (1700).

Data value × (240/204) (2)

As described above, the size is converted so that the remote control unit 2 can convert the remote control unit 2 into a state that can be output to the second information display unit 21 as described above.

However, when the value corresponding to the sub function disxy (str) is not "3", the remote control unit 2 immediately returns the second information display unit 21 to the data received by the main control unit 1 without any calculation. Output through (1700).

However, when the values of the fifth and sixth communication lines A5 and A6 are not all "1", the remote control unit 2 has both the values of the fifth and sixth communication lines A5 and A6 to "0". In operation 2000, when all are 0, the remote controller 2 determines that the data transmitted from the main controller 1 is data indicating the type of information output to the first information display unit 11. .

Therefore, the remote control unit 2 functions to display the type of information output through the first information display unit 11 of the main control unit 1 on the second information display unit 21. After outputting the corresponding information by using (2000), it is determined whether the number indicating the type of information has increased (2600).

However, when the values of the fifth and sixth communication lines A5 and A6 are not all zeros, the remote controller 2 has the value of the fifth communication line A5 as "0" and the sixth communication line A6. It is determined whether the value of) is "1" (2200).

Therefore, when the value of the fifth line A5 is "0" and the value of the sixth line A6 is "1", the remote control unit 2 transmits data transmitted from the main control unit 1 to the main control unit 1. When the operation state of the) is changed, it is determined as data according to the changed operation state.

Therefore, the second control unit 21 displays the main state of the second information display unit 21 so that the operation state of the main control unit 1 can be known by the received data determined by using the function value of the sub-function (ad-conv (str)) in the remote control unit 2. After outputting the operating state of the controller 1 (2300), it is determined whether the number indicating the type of information has increased (2600).

However, when the value of the fifth communication line A5 is not "0" and the value of the sixth communication line A6 is not "1", the remote control unit 2 does not have the value of the fifth communication line A5. In operation 1400, it is determined whether the value of the sixth communication line A6 is “0”.

Therefore, when the value of the fifth communication line A5 is "1" and the value of the sixth communication line A6 is "0", the remote control unit 2 determines that the data remote unit transmitted from the main control unit 1 is the main control unit. When the type of error occurring during the operation of (1) is varied, it is determined as data for transmission to the remote control unit 2.

Therefore, after the remote control unit 2 outputs the type of error occurring in the main control unit 1 to the second information display unit 21 using the function value of the sub function ad-conv (str) (2500), It is determined whether the number indicating the type of information has increased (2600).

However, when the value of the fifth communication line A5 is not "1" and the value of the sixth communication line A6 is not "0", the remote control unit 2 determines whether the number indicating the type of information has increased. Determine (2600).

Therefore, when selecting the rectification of the information to be output from the remote control unit 2, the function value of the sub function (disxy (str)) is increased by the operation of the number increasing switch S221 which can sequentially increase the selection number. When the number indicating the type of information is determined to be increased, the remote control unit 2 displays the type of information corresponding to the increased number on the second information display unit 21 (2700), and the remote control unit 2 Called by the subfunction trans (7) (2800).

The sub function trans (str) outputs an interrupt request signal to the main control unit 1, receives a response signal from the main control unit 1, and then transmits a corresponding remote. (str) allows the main control unit 1 to know the transmission data transmitted from the remote control unit 2 according to the variable value Str.

Table 3 below shows the relationship of the transmission data according to the variable value Str of the subfunction trans (str).

TABLE 3

Therefore, the remote control unit 2 calls the subfunction trans (7) to transmit the interrupt request signal to the third control line A3 to the main control unit 2, and then the main control unit 1 to the fourth communication line. When the response signal is received through (A4), the remote control unit 2 converts the function value of the subfunction trans (7) and transmits it to the second water line A2.

Therefore, the main controller 1 determines the data received by the sub function trans (7), and the number increasing switch S221 of the second switch unit 22 is operated to increase the number indicating the type of information. Can be detected so that the corresponding operation can be performed.

However, when the number increasing switch S221 of the second switch unit 22 is not operated and the number indicating the type of information to be output is not increased, or the operation of the number increasing switch S221 of the second switch unit 22 is not increased. When the corresponding operation is completed, the remote control unit 2 determines whether the number indicating the type of information has decreased (2900).

When selecting the type of information to be output from the remote control unit 2, the operation of the number reduction switch S222 of the second switch unit 22 which can sequentially decrease the selection number is a subfunction (disxy (str)). When the function value of) decreases, the remote control unit 2 determines that the number indicating the type of information has decreased.

Accordingly, the remote control unit 2 displays the rectification of the information corresponding to the reduced number on the second information display unit 21 (3000), and the remote control unit 2 calls the subfunction trans (8) (3100). ).

Therefore, the remote control unit 2 converts the function value of the sub function trans (8) into a form which can be transmitted to the second transmission / reception line A2 through the operation described above using the sub function trans (8). Send.

Therefore, the main control unit 1 detects that the number reduction switch S222 of the second switch unit 22 is operated in the remote control unit 2 using the received data, and the number indicating the type of information is reduced. To perform the operation.

However, when the number reduction switch S222 of the second switch 22 is not operated and the number indicating the type of information to be output is not decreased, or the operation of the number reduction switch S222 of the second switch unit 22 is not reduced. Accordingly, when the corresponding operation is completed, the remote controller 2 determines whether the operation control switch unit S21 of the second switch unit 22 that can control the operation of the main controller 1 is operated (3200).

Therefore, when operating the operation control switch S211 of the second switch unit 22 in order to control the operation of the main control unit 1 from the remote control unit 2, the remote control unit 2 performs the subfunction trans (1). (3300).

The sub function trans (1) is called by the remote control unit 2 to operate the second switch unit 22 for controlling the operation of the main control unit 1 through the operation described above to the main control unit 1. After outputting the corresponding data so that the control switch S21 is operated, the sub function disp-key () is called (3400).

When the sub function (disp-key) is called, the word "Press any key" is output on the second information display unit 21, so that the first to fifth operation selection positions S211 to S215 of the second switch unit 22 are displayed. Select one of the switches, and when one of the first to fifth operation selection switches S211 to S215 is selected, data corresponding to the selected switch is transferred as a function value of a sub-function (disp-key ()). do.

Therefore, when the value of the subfunction trans () is (1) (3500) (3500), the remote controller 2 determines that the first operation selection switch S211 of the second switch unit 22 is selected. Call the subfunction trans (2) (4000), and if the function value X is "2" (3600), it is determined that the deactivation selection switch S212 of the second switch unit 22 is selected. Call the subfunction trans (3) (4100), and when the function value X is "3" (3700), the third operation selector switch S213 of the second switch section 22 is selected. When it is determined, the sub function trans (4) is called (4200), and when the function value X is "4" (3800), the fourth operation selection switch S214 of the second switch unit 22 is selected. If it is determined that the sub function trans (5) is called (4300), and the function value X is "5" (3900), the fifth operation selection switch S215 of the second switch unit 22 In operation 4400, the sub function trans (6) is called based on the selection.

Therefore, the remote control unit 2 determines the function value X of the sub function disp-key () (3500 to 3900) and calls the sub function trans (2 to 6) corresponding to the function value ( 4000-4400).

Therefore, as described above, the remote control unit 2 is allowed to transmit the transmission data set in the table (3) to the main control unit 1 by the called subfunctions trans (2 to 6). In operation 1200, it is determined whether an interrupt request signal is received from the main controller 1.

Therefore, the operation corresponding to the operation selection switches S211 to S215 selected from the first to fifth operation selection switches S211 to S215 of the second switch unit 22 can be executed by the main control unit 1.

The functions of the switch units S21, S211 to S215, SS221, and S222 of the second switch unit 22 are the same as those of the second switch 12.

However, when the operation control signal is not input to the remote control unit 2, the remote control unit 2 determines whether an interrupt request signal is received from the main control unit 1 (1200).

Therefore, when the state of the second information display unit 21 of the remote control unit 2 changes, the same information can be displayed on the first information display unit 11 of the main control unit 1, and the main control unit 1 The operation of the remote control unit 2 can be controlled.

Therefore, the effect of the present invention operating as described above is that when the operation state of the main control unit is changed so that the state of the information output to the information display unit, the variable information state can be output to the information display unit of the remote control unit main control unit The user can easily operate the operation state by using the information display unit of the remote control unit.

When a corresponding data is transmitted to a main control unit or a remote control unit using a communication line capable of transmitting and receiving data, an interrupt request signal is generated and a corresponding answer signal indicating that the information may be transmitted is then transmitted. Since the state of the control unit receiving the information enables to receive the transmitted data accurately, it is possible to receive the correct information.

In addition, when the main control unit transmits the corresponding information from the main control unit to the remote control unit, the remote control unit knows in advance the type of data to be transmitted so that the data transmitted continuously can be prevented from colliding with each other. Since it can be known in advance, the processing time is reduced because the data processing time is shortened.
