Description

Technical Field

[0001] This utility model relates to the field of computer room equipment technology, specifically to an intelligent fault detection device for computer room equipment with an overdue database. Background Technology

[0002] Existing fault detection devices for data center equipment in overdue payment databases mostly monitor only a single parameter, such as current or temperature, failing to achieve coordinated coverage of current, voltage, and temperature in the core areas of the equipment. Furthermore, they lack automatic emergency mechanisms when faults occur, requiring manual intervention to cut off the power supply, which can easily amplify the impact of the fault due to response delays. At the same time, alarm methods are mostly limited to local notifications, unable to remotely transmit temperature distribution and electrical parameter data at the time of the fault, making it difficult for maintenance personnel to grasp the details of the fault in a timely manner and increasing the difficulty of troubleshooting.

[0003] Therefore, this utility model provides an intelligent fault detection device for data center equipment with an overdue payment database. By integrating multiple modules through a central controller, it achieves synchronous detection of multiple parameters using current sensors, voltage transformers, and thermal imagers. When a fault occurs, it automatically triggers a relay to cut off power and a buzzer to sound a local alarm. Furthermore, it uploads fault data to the cloud via a network card. This helps to improve the problems of incomplete monitoring, lack of automatic protection, and lack of remote management in existing devices, and meets the needs of the data center equipment industry for intelligent fault detection functions for data center equipment with an overdue payment database. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: an intelligent detection device for faults in data center equipment for an overdue database, comprising: a socket, a power cord, a communication network card, a relay, a current sensor, a voltage transformer, a main controller, a buzzer, and a thermal imager; the power cord is electrically connected to the socket, the current sensor is connected in series on the power cord, and the voltage transformer is connected in parallel on the power cord, with their signal output terminals electrically connected to the signal input terminal of the main controller respectively; the relay is connected in series in the main circuit of the power cord, and its control terminal is electrically connected to the control output terminal of the main controller; the thermal imager, the communication network card, and the buzzer are all electrically connected to the main controller, and the communication network card is used to establish a data transmission link with the cloud. This intelligent detection device for faults in data center equipment for an overdue database uses a CETCLQFP48 as the main controller. The device is connected to the data center power supply network via the power cord and electrically connected to the socket. Data center equipment, such as the overdue database server and switches, obtains power through the socket's socket holes, and the power supply circuit of each socket hole is correspondingly adapted to the detection terminal of the HSTS21 current sensor. During operation, a current sensor is connected in series on the power line to collect the equipment's operating current signal in real time. A ZMPT101B voltage transformer is connected in parallel on the power line to synchronously collect the supply voltage signal. Both sensors convert the collected analog signals into recognizable electrical signals and transmit them to the main controller via the ADC sampling interface. Simultaneously, a FLIRLEPT 3.5 thermal imager is installed on the top of the equipment in the computer room, with its lens facing the core heat-generating areas such as the CPU and power module. It establishes communication with the main controller via the SPI interface, collects the surface temperature distribution data of the equipment in real time, and transmits it to the main controller. The NBIoTEC800M communication network card and buzzer are electrically connected to the main controller. An SRD-05VDC-SL-C relay is connected in series in the main power line circuit, and its control terminal is connected to the control output terminal of the main controller.

[0005] Preferably, the thermal imager communicates with the main controller via an SPI or UART interface, and the thermal imager is detachably installed on the top of the equipment in the computer room, with its lens facing the core heat-generating area of ​​the equipment. The communication network card is an NBIoT module, which supports uploading the temperature distribution map and fault information collected by the thermal imager to the cloud via the MQTT protocol. The main controller has a built-in threshold judgment module, which has preset current ratings, voltage ratings, and temperature thresholds that match the equipment in the computer room. The main controller receives signals transmitted from the current sensor, voltage transformer, and thermal imager in real time, and compares each detected value with the preset thresholds one by one. When the current exceeds the rated value, the voltage deviates from the rated range, or is too high or too low, or when the local temperature collected by the thermal imager exceeds the preset threshold, the device is immediately determined to be in a fault risk state, and subsequent emergency actions are triggered.

[0006] Preferably, the main controller has a built-in threshold judgment module with preset current rating, voltage rating, and temperature threshold. When the current value detected by the current sensor, the voltage value detected by the voltage transformer exceeds the corresponding rated value, or the temperature detected by the thermal imager exceeds the preset threshold, the main controller synchronously triggers the relay to disconnect the main power supply circuit and controls the buzzer to start the alarm. After the main controller determines the fault, it synchronously performs three operations: First, it outputs a control signal through the GPIO pin to control the relay to disconnect and cut off the power supply to the faulty device to avoid the fault from escalating. Second, it outputs a high-level signal to the buzzer to trigger the buzzer to sound continuously to realize local fault alarm and remind maintenance personnel to handle it in time. Third, it establishes data interaction with the communication network card through the UART interface and uploads information such as the fault type (overcurrent, overvoltage, overtemperature), the current or voltage value at the time of the fault, and the temperature distribution map collected by the thermal imager to the cloud platform through the MQTT protocol, so that remote maintenance personnel can view the fault details in real time.

[0007] Preferably, the primary side of the voltage transformer is connected to the high-voltage side of the power supply line, and the secondary side is connected to the ADC sampling terminal of the main controller. The socket is provided with socket holes, and the power supply circuit of each socket hole is adapted to the detection terminal of the current sensor. The main controller can identify the fault status of the device connected to a single socket hole. When the device is operating normally, that is, when the detection value does not exceed the threshold, the main controller continuously receives the monitoring data of each module and periodically uploads the device operating status, such as real-time current, voltage, and average temperature, to the cloud through the communication network card. When the maintenance personnel troubleshoot the fault, they can send a reset command through the cloud. The main controller then controls the relay to close, restores the power supply to the device, and the device re-enters the normal monitoring mode, continuously ensuring the stable operation of the overdue database computer room equipment.

[0008] The beneficial effects of this utility model are as follows: 1. This utility model uses a current sensor, a voltage transformer, and a thermal imager to collect data on the current, voltage, and temperature of the core area of ​​the equipment. The main controller compares the data with thresholds in real time. In case of a fault, a relay can be automatically triggered to cut off the power supply, thus preventing the fault from escalating due to overcurrent, overvoltage, or overtemperature. This improves upon the limitations of single-parameter monitoring and reliance on manual power-off, and helps reduce the risk of equipment damage.

[0009] 2. This utility model achieves local real-time alarm by setting up a buzzer, and uploads the fault type, electrical parameter data and temperature distribution map to the cloud by relying on the communication network card, so that maintenance personnel can obtain fault details without having to check on-site one by one. This improves the geographical limitations of traditional local alarms and helps to shorten the fault response and troubleshooting time. Attached Figure Description

[0014] The thermal imager 10 communicates with the main controller 8 via an SPI or UART interface. The thermal imager 10 can be detachably installed on the top of the equipment in the computer room, with its lens facing the core heat-generating area of ​​the equipment. The communication network card 4 is an NBIoT module, which supports uploading the temperature distribution map and fault information collected by the thermal imager 10 to the cloud via the MQTT protocol.

[0015] The main controller 8 has a built-in threshold judgment module with preset current rating, voltage rating and temperature threshold. When the current value detected by the current sensor 6, the voltage value detected by the voltage transformer 7 exceeds the corresponding rated value, or the temperature detected by the thermal imager 10 exceeds the preset threshold, the main controller 8 synchronously triggers the relay 5 to disconnect the main circuit of the power line 2 and controls the buzzer 9 to start the alarm.

[0016] The primary side of the voltage transformer 7 is connected to the high-voltage side of the power supply line 2, and the secondary side is connected to the ADC sampling terminal of the main controller 8; the socket 1 is provided with a seat hole 3, and the power supply circuit of each seat hole 3 is adapted to the detection terminal of the current sensor 6. The main controller 8 can identify the fault status of the equipment connected to a single seat hole 3.

[0017] Working principle: The intelligent fault detection device for the data center equipment of this overdue payment database uses CETCLQFP48 as the main controller 8. The device is connected to the data center power supply network through power line 2 and is electrically connected to socket 1. Data center equipment, such as overdue payment database server and switch, obtain power through socket hole 3 of socket 1, and the power supply circuit of each socket hole 3 is adapted to the detection end of HSTS21 current sensor 6. During operation, current sensor 6 is connected in series with power line 2 to collect the equipment's operating current signal in real time. ZMPT101B voltage transformer 7 is connected in parallel with power line 2 to synchronously collect the supply voltage signal. After the two sensors convert the collected analog signals into recognizable electrical signals, they are transmitted to the main controller 8 through the ADC sampling interface. At the same time, FLIRLEPTON 3.5 thermal imager 10 is installed on the top of the equipment in the computer room, with the lens facing the core heat-generating areas such as the equipment's CPU and power module. It establishes communication with the main controller 8 through the SPI interface, collects the surface temperature distribution data of the equipment in real time, and transmits it to the main controller 8.

SRD-05VDC-SL-C relay 5 is connected in series with the main circuit of power line 2, and its control terminal is connected to the control output terminal of the main controller 8.

[0018] The main controller 8 has a built-in threshold judgment module with preset current ratings, voltage ratings, and temperature thresholds that match the equipment in the computer room. The main controller 8 receives signals transmitted from the current sensor 6, voltage transformer 7, and thermal imager 10 in real time, and compares each detected value with the preset thresholds one by one. When the current exceeds the rated value, the voltage deviates from the rated range, or is too high or too low, or when the local temperature collected by the thermal imager 10 exceeds the preset threshold, the device is immediately determined to be in a fault risk state, and subsequent emergency actions are triggered.

[0019] After the main controller 8 determines a fault, it simultaneously performs three operations: First, it outputs a control signal through the GPIO pin to control the relay 5 to disconnect and cut off the power supply to the faulty device to prevent the fault from escalating. Second, it outputs a high-level signal to the buzzer 9 to trigger the buzzer 9 to sound continuously, realizing a local fault alarm and reminding maintenance personnel to handle it in a timely manner. Third, it establishes data interaction with the communication network card 4 through the UART interface, and uploads information such as the fault type (overcurrent, overvoltage, overtemperature), the current or voltage value at the time of the fault, and the temperature distribution map collected by the thermal imager 10 to the cloud platform via the MQTT protocol, so that remote maintenance personnel can view the fault details in real time.

[0020] When the equipment is running normally, i.e. the detected value does not exceed the threshold, the main controller 8 continuously receives the monitoring data of each module and periodically uploads the equipment operating status, such as real-time current, voltage, and average temperature, to the cloud through the communication network card 4. When the maintenance personnel troubleshoot the fault, they can send a reset command through the cloud, and the main controller 8 will then control the relay 5 to close, restore the power supply to the equipment, and the device will re-enter the normal monitoring mode to continuously ensure the stable operation of the overdue database computer room equipment.
