Abstract

The invention discloses a method for preventing power failure of a server cabinet. The method is to send the detection result to the comparison-drive module to compare with the preset reference current through the input current of the server through the current detection module. Once the input current of the server exceeds the reference, Comparison - the drive module is driven immediately, and the switch control module immediately cuts off the power supply to stop supplying power to the server, thereby avoiding power failure accidents in the entire server cabinet. The beneficial effect of the invention is that when a plurality of servers are placed in the server cabinet, the stable and reliable operation of other servers in the same cabinet will not be affected due to the power supply damage of some of the servers. Its function determines that this method has a very broad development prospect and application value.

Description

Ways to Prevent Power Outages in Server Racks

1. Technical field

The invention relates to the field of computer power supply, in particular to the power supply safety of server cabinets.

2. Technical background

Due to the rapid development of informatization, servers are responsible for more and more key applications in many industries, and servers are usually required to run continuously and stably 7x24. To meet such high requirements, the basic premise is to ensure uninterrupted and stable power supply. Therefore, specific measures such as configuring UPS and redundant power supply are indispensable. However, in many occasions, unexpected situations still occur, especially for applications such as cabinets, where many servers are usually placed in one cabinet, and The power supply of each server is not independent, and the power supply load of the entire cabinet is also limited. Therefore, in this case, if the power supply of some servers is damaged, especially a short-circuit fault occurs, the large current generated by these faulty power supplies will be It will trigger the "switch" of the cabinet to protect and cut off the power supply of the entire server cabinet, causing other servers in the same cabinet to also be paralyzed.

In view of this, it is necessary to propose a method that can prevent server cabinets from being powered off.

3. Contents of the invention

The purpose of the method for preventing power failure of the server cabinet of the present invention is to solve the fault that the entire server cabinet is powered off due to a single server power supply being damaged and generating a large current.

The purpose of the method for preventing server cabinets from being powered off in the present invention is achieved in the following manner, the input current of the server is detected by the current detection module, and the current detection module sends the detection result to the comparison-drive module to compare with the preset reference current, Once the input current of the server exceeds the reference, the comparison-driving module immediately drives the switch control module to cut off the power supply and stop supplying power to the server, thereby avoiding a power failure accident in the entire server cabinet.

The beneficial effect of the invention is that when a plurality of servers are placed in the server cabinet, the stable and reliable operation of other servers in the same cabinet will not be affected due to the power supply damage of some of the servers. Its function determines that this method has a very broad development prospect and application value.

4. Description of drawings

Accompanying drawing 1 is the circuit schematic diagram of the method for preventing server cabinet from powering off.

5. Specific implementation

The method for preventing power failure of the server cabinet according to the present invention will be described in detail below with reference to the accompanying drawings.

First, the input current of each server is detected one by one through the current detection module, and the detection result is compared with the preset reference current. Once the input current of a certain server exceeds the reference, the comparison-drive module drives the control switch and the control module immediately disconnects the input current exceeding the reference. The server and the electrical module circuit make it power off, and the alarm module immediately sends out an audible and visual alarm, thereby avoiding power failure accidents in the entire server cabinet.

The server cabinet power-off circuit is composed of a power supply module (1), a current detection module (2), a comparison-drive module (3), a switch control module (4), and an alarm module (5), wherein:

The power supply module (1) is responsible for providing power to the current detection module (2), the comparison-drive module (3), the switch control module (4) and the alarm module (5), so as to ensure the normal operation of each functional module;

The current detection module (2) adopts a current sensor, which is responsible for collecting the input current of a single server and performing current-voltage conversion;

The comparison-drive module (3) is responsible for comparing the collected input current with the reference, and at the same time provides a suitable drive signal for the switch control module (4);

The switch control module (4) adopts an electronic switch, and controls the "on" and "off" actions of the electronic switch according to the drive signal provided by the comparison-drive module (3), so as to maintain or disconnect the power supply of a single server;

The alarm module (5) can use light signals or sound signals, and when the power supply of a single server is "disconnected", an alarm signal will be sent, so that maintenance personnel can take relevant measures conveniently.

The switch control module (4) adopts an electronic switch, and controls the "on" and "off" actions of the electronic switch according to the drive signal provided by the comparison-drive module (3), so as to maintain or disconnect the power supply of a single server;

The alarm module (5) can use light signals or sound signals, and when the power supply of a single server is "disconnected", an alarm signal will be sent, so that maintenance personnel can take relevant measures conveniently.

Claims (2)

1. prevent the method for server cabinet outage, it is characterized in that it being the input current that detects server by current detection module, current detection module send comparison-driver module and the reference current that sets in advance to compare testing result, in case the input current of server exceeds benchmark, comparison-driver module driving switch control module deenergization immediately stops to this server power supply, thereby avoids the whole server cabinet generation loss of power accident.

2. the server cabinet breaker device that prevents according to claim 1 is characterized in that comprising: supply module (1), and current detection module (2), comparison-driver module (3), switch control module (4), alarm module (5), wherein:

Supply module (1) is responsible for to current detection module (2), comparison-driver module (3), and switch control module (4) and alarm module (5) provide power supply, to guarantee each functional module operate as normal;

Current detection module (2) adopts current sensor, is responsible for gathering the input current of separate unit server, and carries out the conversion of current-voltage;

Comparison-driver module (3) is responsible for the input current that collects is compared with benchmark, provides suitable drive signal for switch control module (4) simultaneously;

Switch control module (4) adopts electronic switch, and the drive signal control electronic switch that provides according to comparison-driver module (3) " lead to " and " breaking " moves, and reaches to keep or disconnect the purpose that the separate unit server is powered;

Alarm module (5) can adopt light signal or voice signal, when the power supply of separate unit server during by " disconnection ", can send alerting signal, thereby the personnel of maintaining easily takes measures on customs clearance.
