CRPS (Common Redundant Power Supplies) plays an important role in the operation of servers as an energy conversion and supply part of server equipment. However, currently, real-time detection of output power is only performed at the output of the CRPS.

In order to make the technical field better understand the solution of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and the detailed description. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a CRPS circuit according to the present invention, where the CRPS circuit may include:

the CRPS circuit body 10.

The CRPS circuit body 10 represents an original CRPS circuit, and the specific circuit configuration thereof can be set and adjusted according to actual needs, for example, the general CRPS circuit body 10 may include the power frequency rectifying circuit 11, the PFC circuit 12, the LL C circuit 13 and the high frequency rectifying circuit 14 in fig. 2, of course, the specific circuit configurations of the power frequency rectifying circuit 11, the PFC circuit 12, the LL C circuit 13 and the high frequency rectifying circuit 14 and the types of relevant components in the circuit may also be set and selected according to actual needs, and reference may be made to the existing relevant circuit configurations, which will not be described in detail herein.

A voltage detection means 20 for detecting an input voltage of the CRPS circuit main body 10;

a current detection means 30 for detecting an input current of the CRPS circuit body 10.

In the present embodiment, the CRPS circuit is provided with the voltage detection device 20 and the current detection device 30, the voltage detection device 20 can detect the input voltage of the CRPS circuit body 10, the current detection device 30 can detect the input current of the CRPS circuit body 10, and the other CRPS circuit parameters can be calculated based on the input voltage of the CRPS circuit body 10 detected by the voltage detection device 20 and the input current of the CRPS circuit body 10 detected by the current detection device 30.

It should be noted that the voltage detection device 20 and the current detection device 30 may be normally detected in real time or may be detected at a predetermined detection cycle, but if the detection is performed at a predicted detection cycle, the detection is normally performed at a short detection cycle.

The specific circuit configuration of the voltage detection device 20 and the current detection device 30 can also be set and adjusted according to actual needs, and the CRPS circuit body 10 receives an alternating current, i.e., an AC input shown in fig. 1, which is usually the commercial power.

And a first parameter determining module 40 connected to the voltage detecting device 20 and the current detecting device 30 respectively for determining instantaneous circuit parameters according to the input voltage and the input current.

A BMC50 coupled to the first parameter determination module 40 for receiving output data of the first parameter determination module 40.

In practical applications, the instantaneous circuit parameter determined by the first parameter determining module 40 may generally include 6 items, specifically: instantaneous apparent power at the input end of the CRPS circuit body 10, instantaneous active power at the input end of the CRPS circuit body 10, instantaneous reactive power at the input end of the CRPS circuit body 10, instantaneous power factor of the CRPS circuit body 10, instantaneous input voltage of the CRPS circuit body 10, and instantaneous input current of the CRPS circuit body 10. The instantaneous input voltage of the CRPS circuit body 10 is the detection value of the voltage detection device 20, the instantaneous input current of the CRPS circuit body 10 is the detection value of the current detection device 30, and the rest four parameters are calculated values.

Of course, in other embodiments, the determined instantaneous circuit parameter may also include other things, for example, in the embodiment of fig. 2, the first parameter determining module 40 may include:

preceding stage parameter determining means 41 connected to the voltage detecting means 20 and the current detecting means 30, respectively, for determining from the input voltage and the input current: instantaneous apparent power at the input end of the CRPS circuit main body 10, instantaneous active power at the input end of the CRPS circuit main body 10, instantaneous reactive power at the input end of the CRPS circuit main body 10, instantaneous power factor of the CRPS circuit main body 10, instantaneous input voltage of the CRPS circuit main body 10, and instantaneous input current of the CRPS circuit main body 10;

the subsequent parameter determination unit 42, which is connected to the previous parameter determination unit 41 and the BMC50, determines the power efficiency of the CRPS circuit main body 10, and outputs the output data of the previous parameter determination unit 41 and the power efficiency to the BMC 50.

In this embodiment, the preceding-stage parameter determination unit 41 determines the 6 commonly used circuit parameters, the subsequent-stage parameter determination unit 42 determines the power efficiency of the CRPS circuit body 10, and the subsequent-stage parameter determination unit 42 outputs the output data of the preceding-stage parameter determination unit 41 and the power efficiency to the BMC 50. In this embodiment, the subsequent parameter determining unit 42 needs to obtain circuit data of the output end of the CRPS circuit main body 10, specifically, needs to obtain the instantaneous active power of the output end of the CRPS circuit main body 10, and then, in combination with the instantaneous active power of the input end of the CRPS circuit main body 10, the electric energy efficiency of the CRPS circuit main body 10 can be determined.

In this embodiment, the BMC50 can acquire the power efficiency, so that a user can conveniently know the CRPS circuit condition more carefully, which is also beneficial to maintaining and adjusting the system.

It is also noted that it is considered that the circuit originally has a relevant control unit for controlling the PFC circuit 12 in the CRPS circuit body 10, and originally has a relevant control unit for controlling the LL C circuit 13 in the CRPS circuit body 10.

In a specific embodiment of the present invention, the former stage parameter determining unit 41 may be a PFC control unit of the PFC circuit 12 in the CRPS circuit main body 10, and the latter stage parameter determining unit 42 may be a LL C resonance control unit of the LL C circuit 13 of the CRPS circuit main body 10.

That is to say, in this embodiment, the former stage parameter determining unit 41 and the latter stage parameter determining unit 42 of the present application are implemented by directly using the original PFC control unit of the PFC circuit 12 and the original LL C resonance control unit of the LL C circuit 13, which is beneficial to reducing the cost of the present application and facilitating implementation.

In addition, in the foregoing embodiment, in order to more precisely understand the circuit condition of the user, the subsequent parameter determination unit 42 is used to determine the power efficiency of the CRPS circuit body 10 and output the determined power efficiency to the BMC50, and in other embodiments, the BMC50 may calculate the power efficiency. For example, in the embodiment of fig. 2, the subsequent stage parameter determination unit 42 may be configured to transfer the received output data of the previous stage parameter determination unit 41 to the BMC50 only, without participating in the arithmetic processing of the data. It will be appreciated that such an approach may take up more of the computing resources of the BMC 50.

In a specific embodiment of the present invention, considering that in addition to the instantaneous circuit parameters, in practical applications, the user may also need the average circuit parameters of the input end of the CRPS circuit main body 10 to know the overall state of the circuit in a period of time, therefore, this embodiment may further include:

and a second parameter determination module respectively connected to the voltage detection device 20, the current detection device 30 and the BMC50, for determining an average circuit parameter according to the input voltage and the input current, and outputting the average circuit parameter to the BMC 50.

The specific parameter items in the average circuit parameters may also be set and adjusted according to actual needs, for example, in a specific embodiment of the present invention, the average circuit parameters determined by the second parameter determining module may include: the average apparent power at the input end of the CRPS circuit body 10 in the first time period, the average active power at the input end of the CRPS circuit body 10 in the first time period, the average reactive power at the input end of the CRPS circuit body 10 in the first time period, the average power factor of the CRPS circuit body 10 in the first time period, the average input voltage of the CRPS circuit body 10 in the first time period, and the average input current of the CRPS circuit body 10 in the first time period.

In this embodiment, the average circuit parameter determined by the second parameter determining module is relatively comprehensive, and is convenient for a user to use and observe. It should be noted that, in some cases, when the average circuit parameter needs to be obtained, the average circuit parameter may also be obtained by the first parameter determining module 40, that is, the function of the second parameter determining module may be integrated in the first parameter determining module 40, for example, the function of the preceding stage parameter determining unit and the function of the second parameter determining module may be realized by the same controller, and the implementation of the present invention is not affected.

In a specific embodiment of the present invention, the present invention can further include:

and the display device is connected with the BMC50 and is used for displaying the data received by the BMC 50. The display device can display the data received by the BMC50, so that a user can visually observe the condition of the CRPS circuit on site.

Further, in order to facilitate remote observation, the method may further include:

the wireless transmission device connected with the BMC50 is used for wirelessly transmitting the data received by the BMC50 to a remote terminal, so that a user can know the condition of the CRPS circuit at a remote end without being on site, and the work of the user is facilitated.

In the solution of the present application, the voltage detection device 20 and the current detection device 30 are directly provided in the CRPS circuit to detect the circuit parameters at the input terminal of the CRPS. Specifically, the voltage detection device 20 may detect the input voltage of the CRPS circuit body 10, and the current detection device 30 may detect the input current of the CRPS circuit body 10. The first parameter determining module 40 is connected to the voltage detecting device 20 and the current detecting device 30, respectively, and determines the instantaneous circuit parameter according to the input voltage and the input current, and then outputs the instantaneous circuit parameter to the BMC 50. Therefore, according to the scheme of the application, a user does not need to use an additional power meter to detect the circuit parameters of the CRPS input end, and the user can directly acquire the circuit parameters of the CRPS input end from the BMC50, so that the detection and acquisition of the circuit parameters of the CRPS input end can be conveniently performed. In addition, since the removal is not required as with a power meter, the problem that the maintenance of the server system is not facilitated due to the failure of detection after the removal does not occur.
