[0042] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings.
[0043] like Figure 1 As shown, an embodiment of the present utility model provides a server power supply system, which is installed in a server cabinet and includes at least one power supply module, a monitoring module, and a monitoring adapter board;
[0044] The power module is connected to the power-consuming equipment in the server cabinet and is used to supply power to the power-consuming equipment;
[0045] The first end of the monitoring adapter board is connected to the power module, and the second end is connected to the monitoring module; the monitoring adapter board includes a storage circuit and a power module monitoring signal transfer circuit, the storage circuit is used to store the production and manufacturing information and maintenance information of the power supply system; the power module monitoring signal transfer circuit is used to transfer the monitoring signal in the power module to the monitoring module;
[0046] The monitoring module is used to detect the monitoring signal, perform fault detection, alarm reporting and command issuance.
[0047] In the server cabinet of the data center, the power module is responsible for supplying power to electrical equipment such as servers and switches. In order to monitor and control the operating status of the power module, the system is also equipped with a monitoring module. Normally, the installation depth of the power module in the server cabinet is greater than the installation depth of the monitoring module. Power modules are usually larger and require more heat dissipation space. Designing their installation depth to be deeper can make full use of the space in the cabinet and avoid space waste. The monitoring module is relatively small and may need to be plugged and unplugged frequently. It can be installed in a shallower position, making the entire system more compact and improving the space utilization of the cabinet. The present utility model introduces a monitoring adapter plate to match the depth difference between the power module and the monitoring module in the server cabinet. The embodiment of the present utility model has no special restrictions on the shape and size of the monitoring adapter plate. In actual application, it needs to be matched and designed according to the structure of the entire power system. For example Figure 2 As shown, in an embodiment of the present invention, the monitoring adapter board is generally designed as a long strip-shaped plate structure, with interfaces for connecting to the power module and the monitoring module at both ends respectively. The interfaces are generally designed as quick-plug interfaces to facilitate installation and maintenance.
[0048] The server power system provided by this utility model integrates a storage circuit on a monitoring adapter board, creating a monitoring adapter board with data storage capabilities. This storage circuit is used to record the power system's manufacturing and maintenance information, resolving a series of issues caused by the lack of manufacturing and maintenance information in the power system and providing a physical foundation for the intelligentization of the server power system.
[0049] In the embodiment of the present utility model, the storage circuit and the power module monitoring signal adapter circuit are arranged independently, and the storage circuit is arranged near the second end of the monitoring adapter board. Figure 2 As shown in the figure, area A is the location of the storage circuit, located near the second end of the monitoring adapter board. The second end of the monitoring adapter board is connected to the monitoring module. Placing the storage circuit near the second end of the monitoring adapter board, close to the monitoring module, reduces the distance between the storage circuit and the monitoring module, thereby reducing data loss and interference caused by high-speed communication.
[0050] In the embodiment of the present invention, the design of the storage circuit should consider the following points:
[0051] 1. Power supply filtering: To ensure the stability of the power supply and reduce noise interference, necessary power supply filtering measures should be added to the storage circuit.
[0052] 2. Signal amplitude clamping: To protect the circuit from overvoltage, the signal amplitude should be clamped to ensure that the signal is within a safe range.
[0053] 3. In terms of signal routing, clock and data signals can be routed using differential routing. Differential routing can effectively improve signal transmission performance and reduce electromagnetic interference and signal distortion.
[0054] In an embodiment of the present invention, the storage circuit includes a storage chip and an isolation chip, and the storage chip is connected to the monitoring module via the isolation chip. The storage chip is used to store the production and manufacturing information and maintenance information of the power supply system; the isolation chip is used to isolate abnormal amplitude signals input from the front end to avoid damage to the storage chip. The isolation chip can also be replaced by a driver chip. In an embodiment of the present invention, the storage chip selects a non-volatile memory, such as EEPROM or Flash. In actual applications, a storage chip of corresponding capacity is selected according to specific storage requirements.
[0055] In some embodiments of the present invention, the monitoring module is of pluggable design, and the storage circuit further includes a TVS tube, which is located at the front end of the isolation chip. The TVS tube is used to prevent the impact generated when the monitoring module is hot-plugged and protect the subsequent circuit. Specifically, the storage circuit is connected to the MCU in the monitoring module, and the storage chip in the storage circuit can be read and written through the MCU of the monitoring module, and the storage chip can also be read and written through other hardware devices. The specific information written includes system serial number, manufacturer, production date, test date, calibration date, maintenance record entries, maintenance personnel information, maintenance device list, user information, etc., which may involve various types of information related to equipment assets. In order to reduce unnecessary communication overhead and delay, the simplest communication form is used between the storage circuit and the MCU of the monitoring module, such as I2C communication, which can realize data reading and writing through three signals: data, clock, and write.
[0056] Because the monitoring module is usually a pluggable design, the embodiment of the present invention integrates the storage circuit into the monitoring adapter board. Even if the monitoring module is temporarily removed or replaced, the monitoring adapter board is still connected to the power module, and the storage circuit still corresponds to the storage data of the original power system, and there will be no data matching error problem.
[0057] In some embodiments of the present invention, the storage circuit is powered by the power module. The output of the power module typically requires DC / DC conversion to an appropriate voltage before powering the storage circuit. Since the storage circuit is powered by the power module, even if the monitoring module is removed, the storage circuit can still be accessed through other hardware devices.
[0058] In other embodiments of the present invention, the storage circuit is powered by the monitoring module. The monitoring module contains numerous chips that require a variety of operating voltages. To ensure the proper operation of these chips, the monitoring module is typically equipped with multiple power management units to provide the required multiple operating voltages. In this case, the storage circuit is powered by the monitoring module, allowing the power management units in the monitoring module to be reused, providing a more stable power output for the storage circuit and simplifying the design of the power module.
[0059] In the embodiment of the present invention, the chip in the power module monitoring signal transfer circuit is packaged using surface mount packaging, and the memory chip and the isolation chip are also packaged using surface mount packaging. The use of surface mount packaging can effectively improve production and manufacturing efficiency and enhance product reliability.
[0060] In the embodiment of the present invention, the power module monitoring signal transfer circuit is used to provide a monitoring signal communication connection between the power module and the monitoring module. In order to enhance the communication quality, a terminal resistor, a matching resistor and a short-circuit wire are usually set in the power module monitoring signal transfer circuit.
[0061] In an embodiment of the present invention, the monitoring adapter board is a multi-layer PCB board, the storage circuit is located on the top layer of the monitoring adapter board, and the monitoring signal is arranged in the middle layer to achieve a better shielding effect. The storage circuit is located on the top layer, and the monitoring signal is arranged as much as possible in the middle layer to facilitate wiring, maintenance and debugging of the storage circuit, facilitate heat dissipation, and reduce the impact of external signals on the monitoring signal. In actual applications, the number of layers of the monitoring adapter board is set according to the specific number and type of communication signals in the power module monitoring signal transfer circuit. Through reasonable signal routing design, the monitoring signal is shielded as much as possible in the inner layer of the PCB board. For example, taking a 4-layer PCB board as an example, the storage circuit is set on the top layer, and the ground signal is laid on the bottom layer for shielding the ground. The remaining monitoring signals are passed through the middle layer as much as possible.

Resistors R8, R9, and R10 are all pull-up resistors. Resistors R8 has a resistance of 10KΩ, and resistors R9 and R10 both have resistances of 4.7KΩ. The power pin VCC of the EEPROM M24128 is connected to the 3.3V power supply and is also connected to ground via a second capacitor C13 with a capacitance of 0.1uF.
