The mode selection module 20 transmits mode selection data on what the selected mode is to the control unit 10.

1.3. Error detection unit 100

The error detection unit 100 is a component that detects occurrence of at least one abnormal situation occurring in hardware or peripheral devices constituting the BSC.

The error detection unit 100 of the present invention may operate differently according to the three operation modes of the present invention described above. Hereinafter, the operation of the error detection unit 100 of the present invention in each operation mode will be described.

The error detection unit 100 detects an abnormal situation occurring in hardware or peripheral devices constituting the BSC as an error during operation.

The following are possible abnormal situations that may occur.

(1) The first abnormal situation

One or all of the hard disks (HDDs) configured in a battery system controller (BSC) are separated from the battery system controller (BSC), and a hard disk recognition error occurs.

(2) Second abnormal situation

This is a situation in which the used capacity of the hard disk (HDD) configured in the BSC (Battery System Controller) is filled with a pre-set first reference value (normal maximum usage) or more.

(3) 3rd abnormal situation

This is a situation in which the memory usage capacity of the Battery System Controller (BSC) is filled with a second reference value (normal maximum usage) or more.

(4) 4th abnormal situation

One of the power supplies supplying power to the BSC (Battery System Controller) is separated from the BSC (Battery System Controller), and a power supply recognition error occurs.

(5) 5th abnormal situation

This is a situation in which the temperature of a CPU (Central Processing Unit) configured in the Battery System Controller (BSC) rises above a preset limit temperature.

The error detection unit 100 reads a system event recording unit (system event recording file) in which the BSC control unit of the BSC (Battery System Controller) records overall system status data or battery status at predetermined time intervals, It detects that an abnormal situation has occurred.

That is, the error detection unit 100 of the present invention is to prevent continuous operation without the operator unaware of the occurrence of abnormal situations including the first to fifth abnormal situations detected by the BSC control unit and recorded in the system event recording unit. In order to report this to the host controller, an abnormal situation is detected by monitoring the BSC system event recorder.

The error detection unit 100 of the present invention may be configured including the following detailed configuration.

end. System event monitoring unit 110

This is a configuration that monitors the event of an abnormal situation in the BSC system event record. The system event monitoring unit 110 may be integrated and implemented in the control unit 10, and may receive abnormal situation data for the first to fifth abnormal situation occurrence events from the BSC system event recorder.

I. Error determination unit 120

The error determination unit 120 determines whether an error has occurred from the input of the system event monitoring unit 110. In determining whether an error has occurred, different operations may be performed as follows according to the first to third modes.

<Mode 1: operation mode-abnormal situation detection mode>

In the first mode, the error determination unit 120 determines the abnormal situation by receiving abnormal situation data on the abnormal situation occurrence event of the system event monitoring unit 110. In general, a battery system controller (BSC) composed of a window-based industrial PC or server is configured to record overall system state data or battery state in a system event at predetermined time intervals. When an abnormal situation occurs, a system event is generated and recorded. The above-described system event monitoring unit 110 reads this, and the error determination unit 120 receives the data and detects an abnormal situation to determine a system error.

<Mode 2, 3: 1st, 2nd diagnosis mode-H/W error detection mode, system error detection mode>

The apparatus of the present invention can be operated to detect an error in H/W of peripheral devices constituting the BSC in advance. For example, in the case of the first abnormal situation in which a hard disk recognition error occurs because the hard disk constituting the BSC is connected or disconnected from the BSC, when the normal hard disk is disconnected, the BSC control unit records this in a system event and The error detection unit 100 detects an abnormal situation, and the error status reporting unit 200 to be described later reports it to the host controller 300.

However, when there is an error in the hard disk itself, the abnormal situation is not properly recorded in the system event recording unit and the error detection unit 100 cannot detect it.

In the second mode of the present invention, in order to prevent the error detection unit 100 from operating the BSC without detecting the presence or absence of H/W abnormality, an abnormal situation is forcibly generated and the system event recording unit is monitored to prevent the abnormal situation. Detects H/W abnormality by whether it is recorded or not. For this, the error detection unit 100 transmits a diagnostic signal for generating an abnormal situation to each hardware or hardware connection unit or a control unit.

In order to detect the presence or absence of such H/W abnormality, the error determination unit 120 may have a detailed configuration as follows.

(1) first error determination unit 121

The first error determination unit may be configured to determine whether there is an error in the hard disk (HDD) constituting the battery system controller (BSC) according to whether a predetermined first abnormal situation is detected.

First, the first abnormal situation may be a case in which one or all of the hard disks (HDDs) included in the battery system controller (BSC) are separated from the battery system controller (BSC), and an error in recognizing the hard disk occurs.

When the first abnormal situation occurs, if there is no error in the separated hard disk (HDD), a system event for the recognition error at that time occurs, and the corresponding status data is converted to system logging data. It should be recorded in the event log.

In the operation mode (the first mode), the first error determination unit 122 detects a system event related to the hard disk, reads the status data recorded on the hard disk recognition error, and determines that a first abnormal situation has occurred. have. However, this assumes that the hard disk is in a normal state. If the hard disk is not in a normal state, even if the hard disk is removed, the abnormal situation is not recorded in the system event recording unit.

In the first diagnosis mode (second mode), the first error determination unit 121 transmits a hard disk socket disconnection signal as a first diagnosis signal through the control unit 10. The hard disk socket separation signal may be directly transmitted to the control unit 10 by the mode selection signal of the mode selection unit 20.

The hard disk socket of the BSC of the present invention has a switch for disconnecting the hard disk by the hard disk socket separation signal so that the connection of the hard disk can be physically released by the hard disk socket separation signal (first diagnostic signal). can do.

At this time, if the separated hard disk is in a normal state, the first error determination unit 121 will expect the first abnormal situation to be detected through the system event monitoring unit 110. If no abnormal condition is detected in the system event of the system event recording unit, especially if no abnormal condition is detected in the hard disk item, the first error determination unit 121 determines that there is an error in the corresponding hard disk connected to the BSC. do.

When the occurrence of a system event for the hard disk (HDD) recognition error is not detected, the first error determination unit may determine that there is an error in the corresponding hard disk (HDD) and output a first error determination signal indicating this.

Meanwhile, as the first error determination signal is output, state data for a corresponding time point may be recorded in the data recording unit 400 to be described later.

Here, the state data recorded in the data recording unit 400 may include content indicating that the hard disk (HDD) has an error, a corresponding hard disk (HDD) identification number, and the first error determination signal.

The first error determination unit 121 may transmit n hard disk socket separation signals to detect error states of n hard disks connected to the BSC, and read system events for each of the n hard disks of the system event recorder. Put in. This is the same even when the hard disk socket separation signal is transmitted by the control unit 10.

(2nd diagnosis mode)

Meanwhile, the first error determination unit 121 may transmit a first diagnostic signal (hard disk socket separation signal) while connecting a good hard disk to the BSC and read a system event. In this case, the system event is expected to detect the first abnormal situation.

In this case, when the system event monitoring unit 110 fails to detect the first abnormal situation, the first error determination unit 121 determines that there is an error in the BSC operating system, and transmits a system error signal to the data recording unit 400. Print.

(2) the second error determination unit 122

The second error determination unit may be configured to determine whether there is an error in a hard disk (HDD) constituting a battery system controller (BSC) according to whether or not a predetermined second abnormal situation is detected.

The second abnormal situation may be a case in which data is filled in the hard disk HDD with a first reference value (normal maximum usage) or more.

In the first diagnosis mode, if the hard disk (HDD) is in a normal state without errors, when a second abnormal situation occurs, a system event for exceeding the used capacity indicating that the used capacity of the hard disk (HDD) has been exceeded is displayed. It must occur. However, if there is an error in the hard disk (HDD), it may not be normally recognized that the used capacity has been exceeded, and an abnormal phenomenon may occur in which a system event for exceeding the used capacity does not occur.

Accordingly, the second error determination unit detects whether a system event for exceeding the usage capacity of the hard disk (HDD) occurs after the occurrence of the second abnormal situation through monitoring of system status information recorded in a system event, and the If the occurrence of a system event is not detected, it is determined that there is an error in the corresponding hard disk (HDD), and a second error determination signal indicating this may be output.

Here, filling the hard disk (HDD) with data above the first reference value may be implemented by forcibly copying other data. In the diagnosis mode, the second abnormal situation is implemented by a data compulsory write signal as a second diagnosis signal generated by the second error determination unit or the control unit 10.

Meanwhile, as the second error determination signal is output, status data for a corresponding time point may be recorded in the data recording unit 400 to be described later. Here, the state data recorded in the data recording unit 400 may include content indicating that there is an error in the hard disk (HDD) and the second error determination signal.

In the second diagnosis mode, as in the first error determination unit, the second error determination unit or the control unit 10 may transmit a second diagnosis signal (a data compulsory write signal) while a good hard disk is connected.

In this case, the second error determination unit expects to detect a second abnormal situation, but if not, it determines as a system error and outputs a system error signal to the data recording unit 400.

(3) The third error determination unit 123

The third error determination unit may be a component that determines whether there is an error in the BSC (Battery System Controller) hardware according to whether a predetermined third abnormal situation is detected.

The third abnormal situation may be a case in which data is filled in a memory of a battery system controller (BSC) by more than a preset second reference value (normal maximum usage). Accordingly, if there is no error in the memory, a system event for exceeding the used capacity indicating that the current used capacity of the memory has been exceeded should occur as a third abnormal situation occurs. However, if there is an error, the current used capacity is reduced. 2 There may be an abnormal phenomenon in which a system event for exceeding the used capacity does not occur because it is not normally recognized that the standard value has been exceeded.

Accordingly, the third error determination unit detects whether or not a system event has occurred due to an excess of the memory usage capacity through monitoring of system status information recorded in the system event, and if detected, determines that there is no error in the memory. If not, it is determined that it is an error, and a third error determination signal indicating this may be output.

Here, filling data in the memory above the second reference value may be implemented by forcibly copying other data. To this end, the third error determination unit or the control unit 10 transmits a memory compulsory data write signal as a third diagnostic signal to the system.

Meanwhile, as it is determined that there is an error in the memory and a third error determination signal is output, state data for a corresponding time point may be recorded in the data recording unit 400 to be described later. Here, the state data recorded in the data recording unit 400 may include content indicating that there is an error in the memory and the third error determination signal.

In the second diagnosis mode, as in the previous second error determination unit, the third error determination unit or the control unit 10 may transmit a third diagnosis signal (memory data compulsory write signal) while a good memory is connected.

In this case, the third error determination unit expects to detect a third abnormal situation, but if not, it determines as a system error and outputs a system error signal to the data recording unit 400.

(4) the fourth error determination unit 124

The fourth abnormality determination unit may be configured to determine whether there is an error in a power supply supplying power to a battery system controller (BSC) according to whether a predetermined fourth abnormality situation is detected.

The fourth abnormal situation may be a case where a recognition error occurs because one of the power supplies supplying power to the battery system controller (BSC) is disconnected. Accordingly, if there is no error in the separated power supply, a system event for an error in recognizing the power supply must occur. However, if there is an error in the separated power supply, an abnormal phenomenon in which a system event for an error in recognition of the power supply does not occur may occur because it is not normally recognized that it has been disconnected from the Battery System Controller (BSC). have.

Accordingly, the fourth error determination unit detects the occurrence of a system event for an error in recognition of the power supply through monitoring of system state information recorded in the system event, and when detected, the power supply Supply) is determined to have no error, and if not detected, it is determined that there is an error in the corresponding power supply, and a fourth error determination signal indicating this may be output. To this end, the fourth error determination unit or control unit 10 transmits a power supply separation signal as a fourth diagnostic signal to the system. On the other hand, as it is determined that there is an error in the power supply and a fourth error determination signal is output, state data for a corresponding point in time may be recorded in the data recording unit 400 to be described later. Here, the state data recorded in the data recording unit 400 may include content indicating that the power supply has an error, a corresponding power supply identification number, and the fourth error determination signal.

In the second diagnosis mode, the fourth error determination unit or the control unit 10 may transmit a fourth diagnosis signal (power supply separation signal) while a good power supply is connected to the system. In this case, the fourth error determination unit expects to detect a fourth abnormal situation. If not, it is determined that there is a system error in the system, and a system error signal is output to the data recording unit 400.

(5) the fifth error determination unit 125

The fifth error determination unit may be configured to determine whether there is an error in a CPU fan constituting a battery system controller (BSC) according to a temperature of the CPU after a predetermined fifth abnormal situation occurs.

The fifth abnormal situation may be an operation in which the temperature of the CPU rises above a preset limit temperature. In general, the CPU is provided with a CPU fan that lowers the temperature generated during driving and maintains the temperature below a certain temperature. However, if there is an error in the CPU fan, even if the CPU rises above a certain temperature, the function of lowering it cannot be performed normally, and the CPU temperature may remain above a certain temperature.

Accordingly, the fifth error determination unit includes a temperature measurement unit 126 that measures the temperature of the CPU, and is measured by the temperature measurement unit 126 after a predetermined time after the fifth abnormal situation occurs. If it is detected that the CPU temperature exceeds the preset limit temperature, the CPU fan does not operate normally even though the temperature of the CPU has risen above the limit temperature, so that the CPU continues to be above the limit temperature. Therefore, in this case, it is possible to determine that there is an error in the CPU fan and output a fifth error determination signal indicating this.

That is, if the CPU fan is normal while the fifth abnormal situation occurs and the CPU temperature rises above the preset limit temperature, the CPU temperature should drop below the limit temperature, but there is an error in the CPU fan. If so, there will be a phenomenon in which the temperature of the CPU does not drop and the state above the limit temperature continues. Accordingly, the fifth error determination unit determines that there is an error in the CPU fan when it is detected that the temperature of the CPU measured after a predetermined time exceeds the limit temperature in a state in which the temperature of the CPU rises above the limit temperature. will be.

Here, the predetermined time may be set as a time required for the CPU in a state raised above the threshold temperature to fall below the threshold temperature when the CPU Fan operates normally.

In addition, raising the temperature of the CPU may be implemented by increasing the temperature by applying a load to the CPU using, for example, a number of programs uninterruptedly. To this end, the fifth error determination unit or the control unit 10 may transmit a forced CPU driving signal as a fifth diagnostic signal.

On the other hand, as it is determined that there is an error in the CPU Fan and a fifth error determination signal is output, status data for a corresponding point in time may be recorded in the data recording unit 400 to be described later. Here, the state data recorded in the data recording unit 400 may include content indicating that there is an error in the CPU Fan and the fifth error determination signal.

In the second diagnosis mode, the fifth error determination unit or the control unit 10 may transmit a fifth diagnosis signal (forced CPU driving signal) while a good CPU fan is connected. In this case, the fifth error determination unit expects to detect the fifth abnormal situation. If not, it is determined that there is a system error in the system, and a system error signal is output to the data recording unit 400.

(6) Operation of the first to fifth error determination units in mode 1 (operation mode)

The first to second error determination units do not generate separate first to fifth diagnostic signals in mode 1 (operation mode), and read signals from the system event monitoring unit 110 to detect first to fifth abnormal situations. It may be set to determine whether or not.

1.4. Error status report unit (200)

The error status reporting unit determines that there is an error in the hardware constituting the BSC (Battery System Controller) according to whether each of the first to fifth error determination units 121 to 125 recognizes the first to fifth abnormal situations. Accordingly, the error state may be reported to the upper controller 500 of a battery system controller (BSC).

The error status reporting unit reports the state data of the corresponding hardware to the host controller 500 according to the corresponding error determination signal output from each of the first to fifth error determination units 121 to 125 to cause an error in the corresponding hardware. You can tell that there is.

As described above, when each error determination signal is output, the corresponding state data is recorded in the data recording unit 400. Here, the state data includes information on which hardware has an error and an error determination signal corresponding thereto. Accordingly, the error status reporting unit, when each corresponding error determination signal is output from the first to fifth error determination units 121 to 125, extracts the corresponding state data from the data recording unit 400 by using this and the host controller 500 ) To report hardware errors.

end. State data extraction unit 210

When each corresponding error determination signal is output from the first to fifth error determination units 121 to 125, the configuration of extracting state data corresponding to the output error determination signal from among the state data recorded in the data recording unit 400 I can. The state data recorded in the data recording unit 400 includes a corresponding error determination signal, and the state data extraction unit corresponds to the corresponding error determination signal by using the corresponding error determination signal output from the first to fifth error determination units 121 to 125. It can be extracted by identifying state data to be used.

I. Status data transmission unit 220

Accordingly, the state data extracted from the state data extracting unit 210 may be transmitted and reported to the upper controller 500 communicatively connected through the communication unit 300 to be described later together with a corresponding error determination signal.

Accordingly, by receiving a report of the corresponding state data together with the corresponding error determination signal, it is possible to recognize in advance which hardware of the current BSC (Battery System Controller) has an error and before a problem occurs.

Meanwhile, the error status reporting unit may report an error status of hardware constituting a battery system controller (BSC) to the host controller 500 communicatively connected through the communication unit 300.

1.5. Communication Department (300)

The communication unit is a configuration for connecting communication with the host controllers 500 of the battery system controller (BSC), and may use Modbus TCP or CAN communication, for example.

1.6. Data recording unit 400

As described above, the data recording unit may have a configuration in which, as described above, when a corresponding error determination signal is output from the first to fifth error determination units 110 to 150, state data corresponding thereto is recorded. Here, the state data may include content that enables it to know which hardware has an error and a corresponding error determination signal.

In addition, in addition to the case where the error determination signal is output, status information on the entire system, battery status data, and the like may be recorded at predetermined time intervals.

In this way, the present invention simulates assuming at least one abnormal situation, detects an error in the hardware constituting BSC (Battery System Controlle) according to whether or not the abnormal situation is recognized, and reports it to the host controller 500 By doing so, it is possible to detect in advance a problem due to an error in the hardware constituting the BSC (Battery System Controller), and take precautions accordingly, so that the BSC (Battery System Controller) can be safely maintained. Furthermore, by improving the stability of the BSC (Battery System Controller), the energy storage system (ESS) can be operated more stably.

Meanwhile, the hardware constituting the BSC (Battery System Controller) referred to in the present invention may be, for example, a hard disk (HDD), a power supply, a CPU fan, and the like.

2. BSC (Battery System Controller) abnormal situation detection and notification method according to the present invention

A method of detecting and notifying a BSC abnormal situation according to the present invention will be described with reference to FIG. 2.

2.1. Operation mode setting and confirmation step (S50)

The operation mode confirmation step is a step to confirm the operation mode of the device. In the apparatus of the present invention, the setting of the operation mode may be omitted, and if the setting cannot be confirmed, it operates in the operation mode (mode 1) by default.

As described above, the operation mode is an operation mode (mode 1) that detects and reports an abnormal situation occurring during BSC operation, a first diagnostic mode (mode 2) that detects an error of an accessory hardware as a diagnostic mode, and the system It may be set to a second diagnosis mode (mode 3) for detecting an error of.

2.2. Mode 1: Operation mode (S100)

In the operating mode, the system event monitoring step (S110)-abnormal situation detection step (S120)-abnormal situation reporting step (S130).

2.2.1. System event monitoring step (S110)

The system event monitoring step (S110) is a step of detecting a corresponding event from an event recording file or a logging file of an event recording unit that detects and records an event in the BSC system. In this step, the system event monitoring unit 110 reads the system event recorder and transmits the corresponding contents to the error determination unit 120.

2.2.2. Abnormal situation detection step (S120)

The error determination unit 120 reads a corresponding part of the system event record file detected by the system event monitoring unit 110 to determine whether the above-described first to fifth abnormal situations are detected, and this is performed by the error state reporting unit 200. ).

2.2.3. Abnormal situation reporting step (S130)

This is a step in which the error status reporting unit 200, which has received detection of the first to fifth abnormal situations, reports the abnormal situation to the host controller 500.

2.3. Mode 2: first diagnostic mode (S200)

The first diagnosis mode (S200) also has a system event monitoring step (S210)-an abnormal situation detection step (S220)-an abnormal situation reporting step (S230) as in the procedure in the operation mode (S100), but there is a difference in the specific execution step. There is. This is explained below.

2.3.1. System event monitoring step (S210)

(1) Diagnosis signal transmission step (S212)

The system event monitoring step in the first diagnostic mode includes a diagnostic signal transmission step (S212) of generating and transmitting the first to fifth diagnostic signals.

The diagnostic signal transmission step S212 may be a step of causing at least one abnormal situation to occur in hardware constituting a battery system controller (BSC).

As described above, the first diagnostic signal is a hard disk that causes one or all of the hard disks (HDDs) configured in the BSC (Battery System Controller) to be separated from the BSC (Battery System Controller) to cause a hard disk recognition error. It may be a disk socket disconnect signal.

The second diagnostic signal may be a hard disk compulsory recording signal that causes the used capacity of the hard disk (HDD) included in the battery system controller (BSC) to be filled to a pre-set first reference value (normal maximum usage) or more. This may be accomplished by, for example, forcibly copying other data so that the capacity of a specific hard disk is filled with a predetermined first reference value or more.

The third diagnostic signal may be a memory compulsory write signal that causes the memory use capacity of the BSC (Battery System Controller) to be filled above a preset second reference value (normal maximum use). This may be accomplished by, for example, forcibly copying other data and filling it with a second reference value or more, compared to the total used capacity of the memory.

The fourth diagnostic signal may be a power supply blocking signal for physically blocking the connection of a predetermined power supply of the BSC.

Further, the fifth diagnostic signal may be, for example, a control signal for increasing a temperature by applying a load to the CPU by executing a plurality of programs without interruption. The first to fifth diagnostic signals may be generated and transmitted by the control unit 10 or the error detection unit 100, or the first to fifth diagnostic signals may be generated and transmitted by the first to fifth error determination units, respectively.

The diagnostic signal transmission step is a signal for generating at least one abnormal situation among the first to fifth abnormal situations described above. In the present invention, when an abnormal situation that may occur due to an error of the hardware constituting the BSC (Battery System Controller) occurs, the hardware error can be detected in advance according to whether the generated abnormal situation is recognized. I want to.

However, the present invention is not limited thereto, and may be added as long as it is capable of detecting an error in hardware constituting a battery system controller (BSC) other than the above first to fifth situations.

Meanwhile, the host controller 500 may include a Power Conditioning System (PCS), a Power Management System (PMS), Energy Management (EMS), and the like.

(2) System event monitoring step (S110)

After the diagnosis signal is transmitted, the same system event monitoring step as in the mode 1 (operation mode) may be performed.

2.3.2. H/W error determination step (S220)

After performing the system event monitoring step (S110), the first to fifth error determination units determine whether or not there is an error in the H/W that expects the first or second abnormal situation.

As described above, transmission of the first to fifth diagnostic signals in mode 2 (first diagnostic mode) of the present invention expects the occurrence of first to fifth abnormal situations.

That is, the first to fifth diagnostic signals transmitted in the diagnostic signal transmission step (S214) each generate at least one abnormal situation among the first to five abnormal situations. This is the step of determining whether the hardware constituting the BSC (Battery System Controller) has an error.

(1) First HW error determination step (S221)

After the first abnormal situation occurs by the first diagnosis signal by the transmission of the first diagnosis signal, when a system event for a recognition error of the hard disk (HDD) is detected, an error occurs in the corresponding hard disk (HDD). It is determined that there is no error, and if it is not detected, it is determined that there is an error in the corresponding hard disk (HDD), and a first error determination signal indicating this is output. In this way, the operation of determining whether the hard disk (HDD) has an error according to the first abnormal situation may be performed by the above-described first error determination unit 110.

Meanwhile, as it is determined that there is an error in the hard disk (HDD) and a first error determination signal is output, status data for a corresponding time point may be recorded in the data recording unit 400.

(2) The second HW error determination step (S222)

Meanwhile, a second abnormal situation occurs when the usage capacity of the hard disk (HDD) is exceeded by the transmission of the second diagnostic signal. In this case, determining whether the hard disk (HDD) has an error may be determined according to whether a system event occurs due to an excess of the used capacity of the hard disk (HDD). The reason for this is that the second abnormal situation is a situation in which data is filled in the hard disk (HDD) with a first reference value (normal maximum usage) or more. Accordingly, if the hard disk (HDD) is in a normal state without errors, a system event for exceeding the used capacity should be generated when the current used capacity is filled to more than the first reference value so that follow-up measures can be taken on the situation. If there is an error in the hard disk (HDD), an abnormal phenomenon may occur in which a system event for exceeding the used capacity does not occur because it is not recognized normally even if the current used capacity is filled above the first reference value. Accordingly, after a second abnormal situation occurs in which the used capacity of the hard disk (HDD) is filled to more than the first reference value, and a system event for exceeding the used capacity of the hard disk (HDD) occurs, the corresponding hard disk (HDD) If it is determined that there is no error in the device and a system event for exceeding the used capacity does not occur, it can be determined that there is an error in the corresponding hard disk (HDD). When it is determined that there is an error in the hard disk HDD as described above, a second error determination signal indicating this is output, and this operation may be performed by the second error determination unit 120.

On the other hand, as it is determined that there is an error in the hard disk (HDD) and a second error determination signal is output, status data for a corresponding point in time may be recorded in the data recording unit 400.

(3) 3rd HW error determination step (S223)

A third abnormal situation must occur due to the transmission of the third diagnostic signal. The third abnormal situation may be a case in which the used capacity of the memory is exceeded. In this case, the determination of whether the memory has an error may be determined according to the presence or absence of a system event for exceeding the used capacity of the memory. The reason for this is that the third abnormal situation is a situation in which data is filled in the memory more than the second reference value (normal maximum usage) set in advance. Accordingly, if there is no error in the memory, a system event for exceeding the used capacity should occur indicating that the current used capacity of the memory exceeds a certain standard. However, if there is an error in the memory, the current used capacity is reduced. 2 Even if the standard value (normal maximum usage) is exceeded, it may not be recognized normally and an abnormal phenomenon in which a system event for exceeding the usage capacity does not occur may occur. Accordingly, after a third abnormal situation occurs in which the used capacity of the memory is filled to more than the second reference value, when a system event for exceeding the used capacity of the memory occurs, it is determined that there is no error in the memory, and If no system event occurs, it can be determined that there is an error in the memory. When it is determined that there is an error in the memory as described above, a third error determination signal indicating this is output, which may be performed by the third error determination unit 130.

On the other hand, as it is determined that there is an error in the memory and a third error determination signal is output, status data for a corresponding point in time may be recorded in the data recording unit 400.

(4) 4th HW error determination step (S224)

A fourth abnormal situation must occur due to the transmission of the fourth diagnostic signal. After the fourth abnormal situation occurs, determining whether or not a power supply configured in a battery system controller (BSC) has an error may be determined according to state data recorded in a system event of a window. . Specifically, the BSC (Battery System Controller) composed of a window-based industrial PC or server records overall system status data or battery status in a system event at regular intervals. Accordingly, after the fourth abnormal situation occurs in which one of the power supplies supplying power to the BSC (Battery System Controller) is disconnected, the system is in a state in which there is no error in the separated power supply. In the event, the status data on the recognition error at the time should be recorded in the system event of the window. However, if there is an error in the separated power supply, even if it is disconnected from the BSC (Battery System Controller), the recognition error does not occur, and the status data for the recognition error at that time may not be recorded in the system event. have. Accordingly, after the fourth abnormal situation occurs, if the state data on the recognition error of the power supply is recorded in the system event of the window, the power supply is returned to a normal state without errors. I can judge. On the other hand, if the status data on the power supply recognition error is not recorded even though the fourth abnormal situation has occurred, it is determined that there is an error in the power supply and a fourth error determination signal indicating this is output. can do.

In other words, if the occurrence of a system event for an error in recognition of a power supply is detected after the fourth abnormal situation occurs, it is determined that there is no error in the power supply, and if not detected, the corresponding power It determines that there is an error in the power supply and outputs a fourth error determination signal indicating this.

In this way, the operation of determining whether the power supply has an error according to the fourth abnormal situation may be performed by the fourth error determination unit 140.

Meanwhile, as it is determined that there is an error in the power supply and a fourth error determination signal is output, status data for a corresponding time point may be recorded in the data recording unit 400.

(5) 5th HW error determination step (S225)

The fifth abnormal situation must occur due to the transmission of the fifth diagnostic signal. The fifth abnormal situation may be a case where the temperature of the CPU configured in the Battery System Controller (BSC) is exceeded. In this case, determining whether the CPU fan has an error is equal to or greater than a preset limit temperature of the CPU. After the fifth abnormal situation occurs, if the temperature of the CPU measured after a predetermined time exceeds the limit temperature, it may be determined that there is an abnormality in the CPU fan. Specifically, in general, a CPU fan is provided to lower the temperature generated in the CPU when the battery system controller (BSC) is driven. The CPU fan prevents the CPU from exceeding a certain temperature so that it can operate stably. However, if there is a problem with the CPU fan, the CPU temperature may not be able to perform the function to lower the temperature normally and the CPU temperature may exceed a certain temperature. Accordingly, after a fifth abnormal situation occurs in which a load is applied to the CPU by using a number of programs uninterruptedly and intentionally raises the temperature of the CPU above the preset limit temperature, the temperature of the CPU is measured after a predetermined time, If it is detected that the measured temperature exceeds the above limit temperature, the CPU fan has an error and does not operate normally, and the temperature does not drop while the CPU has risen above the limit temperature. It is determined, and a fifth error determination signal indicating this may be output. On the other hand, if the temperature of the measured CPU falls below the limit temperature after a predetermined period of time after the fifth abnormality occurs, the CPU fan has fallen by the normal operation of the CPU fan while the CPU has risen above the limit temperature. It can be determined that there is no error in

Here, the predetermined time may be set as a time required for the CPU in a state raised above the threshold temperature to fall below the threshold temperature when the CPU Fan operates normally.

In this way, the operation of determining whether the CPU fan has an error according to the fifth abnormal situation may be performed by the fifth error determination unit 150.

In the present invention, in the case of the fifth abnormal situation, after raising the temperature of the CPU configured in the actual BSC (Battery System Controller) above the limit temperature, it is determined whether the temperature of the CPU exceeds the limit temperature after the predetermined time. Accordingly, it is possible to determine whether the CPU fan has an error.

On the other hand, as it is determined that there is an error in the CPU Fan and a fifth error determination signal is output, status data for a corresponding point in time may be recorded in the data recording unit 400.

2.3.3. Error status reporting step (S230)

In the error status reporting step, if it is determined that there is an error in the hardware constituting the BSC (Battery System Controller) for at least one of the first to 5 or more situations through the error determination step S220, the corresponding state is BSC. It may be a step of reporting to the upper controller 500 of (Battery System Controller). This can be done by the error status reporting unit 200.

More specifically, when it is determined that there is an error in the hardware constituting the BSC (Battery System Controller) for each of the first to five or more situations in the error determination step (S220), the first to the fifth representing the error. An error determination signal may be output. Therefore, when any one of the first to fifth error determination signals is output, it is reported to the host controller 500 in communication with the BSC (Battery System Controller) indicating which hardware error has been detected according to the error determination signal. can do. In this case, the state data recorded in the data recording unit 400 may be extracted based on the time when the error determination signal is output and reported together. Accordingly, the host controller 500 of the Battery System Controller (BSC) can recognize in advance any problem due to a hardware error constituting the Battery System Controller (BSC).

Here, the BSC (Battery System Controller) and its upper controller 500 may be connected to each other for communication by the communication unit 300.

2.4. Mode 3: 2nd diagnosis mode (S300)

The second diagnosis mode (Mode 3) has the following procedure, and when each H/W connected to the corresponding part is connected to the H/W verified as the H/W in a normal state to detect the first to fifth abnormal situations And in this case, verify the error of the BSC system itself.

Each procedure of the second diagnosis mode S300 is the same as that of the first diagnosis mode S200. However, since each H/W is premised that it has already been verified as good, the system event for each abnormal situation naturally occurs in the H/W error determination step (S220) after the diagnostic signal transmission step (S212). As a premise, if each system event is not detected, it is determined that an error has occurred in another part of the BSC system or the system itself, and this is reported.

3. System operation method

As described above, the present invention relates to a system and method for detecting first to fifth abnormal situations in which a problem occurs in each H/W constituting a BSC system and notifying the host controller to take action.

In operating the system of the present invention, as shown in FIG. 3, prior to entering the operation mode (first mode), test H/Ws verified through the second diagnostic mode are first installed to prevent system defects. Next, after installing the H/Ws to be actually installed, the first diagnostic mode can be performed to detect errors of the actual H/Ws to be used and take preliminary action. After this process, the first mode By operating the system in (operation mode), it can be operated to detect and respond to abnormal situations during operation (operation).

In other words, the BSC including or additionally provided with the hardware error detection device of the present invention corrects or replaces the hardware error by executing the above-described first diagnostic mode execution step for diagnosing the presence of an abnormality in the hardware constituting the BSC. After that, it can be operated in a manner of executing an operating mode (first mode) that detects and reports an abnormal condition of the hardware constituting the BSC, and detects the presence or absence of a system before or after the execution of the first diagnostic mode. It can be operated to execute the above-described second diagnosis mode. When the second diagnosis mode is performed, the first mode (operation mode) may be performed after performing the first and second diagnosis modes, and as needed or periodically during operation of the equipment in the first mode. The first and second diagnostic modes may be performed selectively or both to aid in equipment maintenance.
