Description

[0002] The dynamic environment monitoring system monitors the power equipment (such as DC power supply, distribution panel, battery, etc.) and environmental equipment (such as temperature and humidity, smoke, water immersion, access control, etc.) of the computer room of the IT data center, records and analyzes the relevant data and uploads it for the operation and maintenance personnel to read. Currently, due to the differences in the regions where the computer rooms of various IT data centers are located and the manufacturers of the dynamic environment monitoring systems selected, the acquisition accuracy and intelligence level of the monitoring systems are different, but most of them adopt a simple and effective method in which the user sets the threshold and the collected value exceeds the threshold to alarm. Due to the correlation of the equipment in the computer room, the abnormality of the parameters collected by a certain device may trigger multiple related alarms. The readability of the alarm records is low, and it is difficult for the staff to analyze them to trace the source of the fault.

[0054] Figure 1 A flowchart of a fault judgment method based on alarm information according to an embodiment of the present disclosure is shown. DETAILED DESCRIPTION

[0055] Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0056] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0057] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0058] According to one aspect of the present disclosure, a fault judgment method based on alarm information is provided, the method comprising:

[0059] Acquire monitoring alarm information of a data center computer room; the monitoring alarm information includes alarm information on power supply and alarm information on computer room environment;

[0060] A first-level fault judgment result of the AC power supply voltage is obtained according to the result of the A-phase alarm information, the B-phase alarm information and the C-phase alarm information of the AC power supply voltage after passing through the logic gate; wherein the logic gate includes: an AND gate, an OR gate and a NOT gate;

[0061] The first-level fault judgment result of the AC power supply current is obtained according to the result of the A-phase alarm information, the B-phase alarm information and the C-phase alarm information of the AC power supply current after passing through the logic gate;

[0064] The power supply fault judgment result is obtained according to the result of the first-level fault judgment result of the AC power supply voltage, the first-level fault judgment result of the AC power supply current and the first-level fault judgment result of the rectifier module after the logic gate is passed;

[0065] The battery pack fault judgment result is obtained according to the result after the first-level fault judgment result of the battery pack passes through the logic gate.

[0066] In a possible implementation, the computer room environment alarm result is obtained according to the result of the temperature alarm information, humidity alarm information, water immersion alarm information, and smoke alarm information of the computer room after passing through logic gates.

[0067] The rule items sorted out in the power supply part include abnormal temperature and humidity in the computer room and abnormal environment in the computer room. Confirm the on-site situation, check or adjust the current status of the air conditioner in the computer room, confirm the situation on site according to the diagnosis results, and take corresponding measures.

[0068] The parameters of the power supply equipment in the computer room of the IT data center are highly correlated, and the occurrence and end times of the alarms of the same fault are concentrated in the same time period in an intersecting or adjacent manner. From the details, the monitoring system has the same meaning for the monitoring of the parameters of the communication power supply collected. In other words, the state changes of a device and other devices in the "same group" have similar or identical effects on the entire power system, such as the voltage of the three-phase A, B, and C of the mains input, the output value of the rectifier module when the same power supply is working, and the measured values ​​at both ends of the single battery.

[0069] In a possible implementation, the alarm information of the AC power supply voltage includes: an upper limit exceeding alarm information, a lower limit exceeding alarm information, and a zero value alarm information;

[0070] The first-level fault judgment result of the AC power supply voltage is obtained according to the result of the A-phase alarm information, the B-phase alarm information and the C-phase alarm information of the AC power supply voltage after passing through the logic gate, including:

[0071] If the A-phase alarm information, the B-phase alarm information and the C-phase alarm information of the AC power supply voltage are all 0-value alarm information, the result after the logic gate is that the power supply voltage has no output;

[0072] If the A-phase alarm information, the B-phase alarm information and the C-phase alarm information of the AC power supply voltage are not all lower limit alarm information and at least one of the A-phase alarm information, the B-phase alarm information and the C-phase alarm information of the AC power supply voltage is lower limit alarm information, then the result after the logic gate is that the power supply voltage is phase missing;

[0073] If the A phase alarm information, B phase alarm information and C phase alarm information of the AC power supply voltage are all over-limit alarm information, the result after the logic gate is that the power supply voltage is over-voltage;

[0074] If the A-phase alarm information, the B-phase alarm information and the C-phase alarm information of the AC power supply voltage are all lower limit alarm information at the same time and the A-phase alarm information, the B-phase alarm information and the C-phase alarm information of the AC power supply voltage are not all zero value alarm information at the same time, then the result after the logic gate is that the power supply voltage is undervoltage.

[0075] The introduction of mains power is the power source of the communication room and is the top priority in power monitoring and fault diagnosis. Generally, two three-phase mains power lines, the common line and the backup line, are connected. Common faults that can be directly inferred from the alarm records include no output, phase loss, overvoltage, and undervoltage of the mains circuit. Among them, no output means that the three-phase voltage of this line is 0; phase loss means that the voltage output of one or two phases exceeds the lower limit; overvoltage means that the voltage of one phase exceeds the upper limit; undervoltage means that the three-phase voltage exceeds the lower limit and is not 0. The structure and logic of the mains backup line are exactly the same as those of the common line, so I will not repeat them here.

[0076] In a possible implementation, the alarm information of the AC power supply current includes: an upper limit exceeding alarm information, a lower limit exceeding alarm information, and a zero value alarm information;

[0077] The first-level fault judgment result of the AC power supply current is obtained according to the result of the A-phase alarm information, the B-phase alarm information and the C-phase alarm information of the AC power supply current after passing through the logic gate, including:

[0078] If the A-phase alarm information, the B-phase alarm information and the C-phase alarm information of the AC power supply current are all over-limit alarm information at the same time, the result after the logic gate is the AC output over-current;

[0079] If the A-phase alarm information, the B-phase alarm information and the C-phase alarm information of the AC power supply current are all zero-value alarm information at the same time, the result after the logic gate is that the AC output current is zero.

[0080] The AC power distribution unit is the AC distribution module after the mains power introduction module, which is responsible for AC power distribution, voltage stabilization, circuit protection, etc. The input of the AC panel is the input of the selected route for the mains power introduction. Here, only the two items of AC panel output overcurrent and AC panel output 0 are considered. AC panel output overcurrent means that the current of a certain phase exceeds the upper limit; AC panel output 0 means that all three-phase currents are 0.

[0081] In a possible implementation, according to the output voltage alarm information of the rectifier module, the output current alarm information of the rectifier module is passed through a logic gate to obtain a first-level fault judgment result of the rectifier module, including:

[0082] The rectifier module includes a plurality of rectifier sub-modules;

[0083] If the alarm information of the output voltage of the rectifier module is an over-limit alarm information, the result after the logic gate is that the output of the rectifier module is over-voltage;

[0084] If the alarm information of the output voltage of the rectifier module is the lower limit alarm information, the result after the logic gate is the output undervoltage of the rectifier module;

[0085] If the alarm information of the output voltage of the rectifier module is 0 value alarm information, the result after the logic gate is that the rectifier module has no output;

[0086] If the alarm information of the output current of the rectifier module is an over-limit alarm information, the result after passing through the logic gate is that the output current of the rectifier module is over-current.

[0087] The DC power supply consists of multiple rectifier modules connected in parallel. During operation, designers usually hope that the output current of each rectifier module remains consistent. If the load of the rectifier module is unbalanced, it will affect the service life of the power supply, make the output unstable, and seriously affect the normal operation of the communication equipment. Therefore, according to the standard, the analog calculation quantity rectifier module current imbalance is introduced as a quantitative description of the DC power rectifier module current sharing index.

[0088] The current sharing imbalance is calculated in the following manner: the difference obtained by subtracting the average value of the output currents of N working modules from the limit value of the measured module output current is divided by the rated current value of the module.

[0089] In a possible implementation, according to the output voltage alarm information of the rectifier module, the output current alarm information of the rectifier module is passed through a logic gate to obtain a first-level fault judgment result of the rectifier module, further comprising:

[0090] If the alarm information of the output voltage of at least one rectifier module is an over-limit alarm information, the result after the logic gate is that the rectifier module is partially over-voltage;

[0091] If the alarm information of the output voltage of at least one rectifier module is the lower limit alarm information, the result after the logic gate is that the rectifier module is partially undervoltage;

[0092] If the key information of the output voltage of the rectifier module is not the zero-value alarm information and the alarm information of the output voltage of at least one rectifier module is the zero-value alarm information, the result after the logic gate is that the rectifier module has no output;

[0093] If the alarm information of the current sharing imbalance degree of at least one rectifier module is the upper limit exceeding alarm information, the result after the logic gate is that the output current of the rectifier module is unevenly distributed.

[0094] If the required capacity of a single power supply is 200A, the 7×30A mode can be selected, with a total of 8 (1 redundant standby) rectifier modules working alternately. If the output of all rectifier modules exceeds the lower limit at the same time and an alarm is generated, it is more likely that there is a problem with the AC power supply in the front; conversely, if only one or some of the modules generate an alarm exceeding the lower limit, it is more likely that the alarm module has a fault. Therefore, packaging the rectifier part in "full" and "partial" modes is more conducive to inferring the fault source when an alarm occurs.

[0095] In the rectifier part, the "full" items of concern include rectifier module output overvoltage, output undervoltage, no output, and output current overcurrent. Among them, rectifier module output overvoltage means that the total output voltage of the entire rectifier module exceeds the upper limit; rectifier module output undervoltage means that the total output voltage of the entire rectifier module exceeds the lower limit; rectifier module no output means that the DC power supply output voltage is 0; the total output current of the rectifier module exceeds the upper limit.

[0096] The rectifier module has partial overvoltage, partial undervoltage, partial no output, uneven output current distribution, and partial rectifier failure. Among them, partial overvoltage of the rectifier module means that the output voltage of a rectifier module exceeds the upper limit; partial undervoltage of the rectifier module means that the output voltage of a rectifier module exceeds the lower limit; partial no output of the rectifier module means that the output voltage of a rectifier module is 0 and the total output voltage of the rectifier module is not 0; uneven output current distribution means that the current imbalance degree of a rectifier module exceeds the upper limit.

[0097] In a possible implementation, the first-level fault judgment result of the battery pack is obtained by the result of the logic gate based on the alarm information of the battery pack voltage, the battery pack charge and discharge current alarm information, the voltage information of the single battery in the battery pack, the alarm information of the maximum voltage difference of the battery pack and the fuse alarm information of the battery pack, including: the battery pack includes a plurality of battery cells;

[0098] If the battery pack voltage alarm information is an over-limit alarm information, the result after the logic gate is that the battery pack voltage is over-voltage;

[0099] If the battery pack voltage alarm information is an under-limit alarm information, the result after the logic gate is that the battery pack voltage is undervoltage;

[0100] If at least one battery cell voltage warning message is an over-limit warning message, the result after the logic gate is that the battery cell voltage is over-voltage;

[0101] If at least one battery cell voltage warning information is a lower limit warning information, the result after the logic gate is that the battery cell voltage is undervoltage;

[0102] If the maximum voltage difference alarm information of the battery pack is an over-limit alarm information, the result after the logic gate is that the voltage distribution of the battery cells is uneven.

[0103] For example, the charge and discharge voltage and current of the battery pack are important indicators for judging the working state of the battery pack, especially the current fluctuates greatly in different states. If the battery pack charge and discharge current exceeds the upper limit alarm, it means that the battery is in the charging state. If the battery pack charge and discharge current exceeds the lower limit alarm, it means that the battery is in the discharging state.

[0104] After repeated charge and discharge of the battery pack, due to the individual quality differences between the single cells, "lag cells" may appear, and the output voltage lags significantly behind other batteries. The "lag cells" have large internal resistance and small capacity, which will drag down the entire battery pack, accelerate the aging of the battery pack, shorten the life, and in severe cases may cause loss of control and cause fires and electric shock accidents. Therefore, when "lag cells" are found, they need to be replaced as soon as possible. The maximum voltage difference of the battery pack refers to the difference between the highest and lowest open-circuit voltages between the single cells in the group. For a battery pack composed of 2V single cells, the specification requires that the maximum voltage difference shall not be greater than 20mV. Therefore, it can be used as a monitoring quantity and the upper and lower thresholds can be set to be included in the system, so that "lag cells" can be discovered early and failures can be prevented in time.

[0105] In order to prevent the battery from being damaged by overload or short circuit when the battery is powered, a fuse is installed on the output bus of the battery pack. When the current exceeds the nominal value, the fuse blows and an alarm is issued. The fuse alarm is included in the power system monitoring as a remote signal.

[0106] In a possible implementation, the first-level fault judgment result of the AC power supply voltage, the first-level fault judgment result of the AC power supply current, and the first-level fault judgment result of the rectifier module are obtained through logic gates to obtain a power supply fault judgment result, including:

[0107] If at least one of the following conditions occurs in the common power supply circuit: no power supply voltage output, power supply voltage phase loss, power supply voltage overvoltage, or power supply voltage undervoltage, the power supply fault is judged as an AC common circuit fault;

[0108] If at least one of the following conditions occurs in the backup power supply circuit: no power supply voltage output, power supply voltage phase loss, power supply voltage overvoltage, or power supply voltage undervoltage, the power supply failure is judged as an AC backup circuit failure.

[0109] If both the common power supply circuit and the backup power supply circuit fail at the same time, the power supply failure is judged as a failure of the automatic transfer switch device;

[0110] If the AC output is overcurrent or the AC output current is 0, the power failure judgment result is that the automatic transfer switch device is faulty;

[0111] If the AC output current is 0, the rectifier module has no output, and the battery is in a discharged state, the power failure judgment result is that the AC power supply stops working;

[0112] If part of the rectifier module has no output or the output current of the rectifier module is unevenly distributed, the power supply fault is judged to be a partial DC module failure.

[0113] The rules sorted out in the power supply part include AC common (backup) circuit failure, ATS failure, power supply failure, and partial rectifier module failure.

[0114] No output, phase loss, overvoltage, and undervoltage of the AC common (backup) circuit can all be classified as AC common (backup) circuit faults. At this time, it is necessary to check and troubleshoot the specific AC common (backup) circuit faults that appear in the packaging results.

[0115] When the AC common line and the backup line are not faulty but the AC distribution unit connected to them has abnormal output, it is inferred that the automatic transfer switch ATS (Automatic Transfer Switching, ATS) may be faulty. At this time, you need to manually operate the handle to switch to ensure the normal operation of the power system, and then check the ATS circuit breaker and conversion components.

[0116] There is no output at the AC output terminal and the DC output terminal, and the battery pack is in a discharged state. It can be inferred that the power supply has stopped working and there is no AC input to the power system. It is necessary to further check the mains input, ATS status and related port connections.

[0117] When the rectifier module has no output or the output current distribution is uneven, it is inferred that some rectifier modules may be faulty. At this time, you need to check the AC part, DC part and power-on status of the rectifier module. If it is an uneven current fault, please monitor the corresponding module alarm location and replace the faulty module in time.

[0118] In a possible implementation, obtaining a battery pack fault judgment result according to a result of a first-level fault judgment result of the battery pack after passing through a logic gate includes:

[0119] If the battery pack voltage is undervoltage or the battery cell voltage is undervoltage, the battery pack fault judgment result is that the battery pack is low on power;

[0120] If the battery pack voltage is overvoltage or the battery cell voltage is overvoltage, the battery pack fault judgment result is that the battery pack voltage is too high;

[0121] If the battery pack is not in a charging state and the battery pack voltage is undervoltage, the battery pack fault judgment result is a battery charging device failure;

[0122] If the voltage distribution of the battery cells is uneven, the battery pack fault judgment result is that the voltage distribution of the battery cells is uneven.

[0123] For example, the rule items sorted out by the battery pack include battery pack low power, battery pack voltage is too high, and battery charging device failure.

[0124] The battery pack voltage is too high, which may be caused by the constant current stage at the beginning of charging after the battery pack is used, and the battery voltage upper threshold is set low. At this time, you should stop charging and observe for a period of time after confirming that the alarm is correct.

[0125] When the battery is in the charging state and has already run out of power, it is judged that there may be a problem with the charger. You need to immediately check the charger status and connection status. At this time, the situation is already quite urgent and you must immediately connect the power supply to ensure the normal operation of the communication equipment in the computer room.

[0126] The fuse alarm can be directly classified as a rule item diagnosis result. When this alarm occurs, first determine whether it is caused by discharge or charging overcurrent based on other conditions, and then take measures based on the actual situation.

[0127] The uneven voltage distribution of battery cells can be directly attributed to the rule-based diagnosis results. The large voltage difference between the cells can easily cause overcharging or over-discharging, which shortens the battery life. The problematic battery needs to be replaced as soon as possible.
