Description

System and method for detecting power line in place and electronic equipment

Technical Field

The present invention relates to the field of power technologies, and in particular, to a system and method for detecting an in-place power line, and an electronic device.

Background

Maintenance of the power infrastructure is critical to reducing damage caused by unexpected power outages in data centers. Sudden power outages can put the operation of the data center into paralysis. Power interruption is detrimental to IT systems (IT systems are not directly connected to ground, and exposed conductive portions of electrical devices are connected to ground through protective ground wires) because IT can lead to data loss, file damage, and equipment damage. An on-premise data center requires a backup power system that is directly integrated into the power infrastructure to ensure that critical systems remain online.

The data center power distribution is mainly that power input by AC or DC (Direct Current) is supplied to PSU (Power supply unit power module) of a server or a switch device through an AC (Alternating Current alternating Current) power line connected with a PDU (Power Distribution Unit power distribution unit), and common ICT (information and communications technology information communication technology) equipment adopts an N+N redundant power supply design, so that the power supply stability is ensured. The problem that the AC power cable falls off and is not plugged in often occurs in the data center. The current solution to this problem is to physically fix the cable tie or velcro by means of an AC power cord and a male socket of the PSU power supply. However, the following problems still remain with this solution:

The first problem is: the power supply equipment cannot detect whether poor contact is perceived between the AC power cable and the male socket of the PSU power supply, foolproof (a behavior constraint means for preventing correction) cannot be achieved through a power supply structure and a power supply principle of the power supply equipment, and even though the power supply equipment cannot confirm whether hundred percent coupling and plugging are achieved between the AC power cable and the male socket of the PSU power supply through a physical fixing method such as wire harness buckles or magic tapes;

a second problem: after the AC power cable and the male socket of the PSU power supply are tightly inserted in a coupling way, after a period of use, the situation that the wire harness buckle or the magic tape is cracked, broken or the like is caused by external factors or external forces or the like, or the situation that the wire harness buckle or the magic tape is not cracked, broken or the like is avoided, but other factors cause poor contact between the AC power cable and the male socket of the PSU power supply, and the occurrence of abnormality causes the gradual separation between the AC power cable and the male socket of the PSU power supply. However, the power supply equipment cannot judge the situation, and cannot provide information for the maintenance system to report and pre-warn, so that the power supply is directly cut off, and various problems such as downtime, data loss, file damage, equipment damage and the like of equipment in the data center can be caused.

A third aspect of an embodiment of the present invention provides an electronic device, including a system for detecting an in-place power line according to any one of the first aspect.

The invention provides a system for detecting in-place of a power line, which comprises: a power cord and a power outlet, the power cord configured to be plugged into the power outlet; the power end male socket includes: a first regular end and a first detection end; the power cord includes: a second conventional end and a second detection end. By conventional terminal is understood the structure that is already present on the power cord and the power terminal male socket, for example: a live wire end L, a null wire end N, a ground end GND, etc.; the detection end is a structure which is not provided on the prior power line and the prior power end male socket, and is invented by the invention.

In the structure, the power line and the power end male socket are just matched with each other, so that the structures of the power line and the power end male socket can be mutually interchanged. If the first regular end and the first detection end are in convex shapes, the second regular end and the second detection end are in concave shapes, and the first regular end and the first detection end can be matched with each other. In the case that the first detecting end is in a convex shape, the length of the first detecting end must be smaller than that of the first regular end, and the length of the first regular end is equal to the depth of each of the second regular end and the second detecting end.

The reason for this design is: in order to ensure that the first and second sensing terminals are tightly coupled after the two conventional terminals are tightly coupled, and since the length of the first sensing terminal is smaller than that of the conventional terminal, if the two sensing terminals are tightly coupled, the two conventional terminals are also positively tightly coupled. Therefore, the power supply equipment can sense whether the contact between the AC power supply cable and the male socket of the PSU power supply is bad after the AC power supply cable is inserted into the male socket of the PSU power supply by detecting whether the two detection ends are tightly inserted and coupled, and if the contact is bad, the power supply equipment can immediately send information to a maintenance system for reporting and early warning. And the shorter the first detection end, the more accurate the power supply device will be to confirm whether one hundred percent coupling is achieved between the AC power cable and the male receptacle of the PSU power source.

In addition, after a period of use, when the conditions of splitting, breaking and the like of the wire harness buckle or the magic tape are caused by external factors or external forces and the like, or the conditions of splitting, breaking and the like of the wire harness buckle or the magic tape are not caused, but the problem that the contact between the AC power cable and the male socket of the PSU power supply is poor due to other factors, and the problem that the AC power cable and the male socket of the PSU power supply are separated slowly due to the abnormality is solved well is solved. Because the two sensing terminals must be disconnected before the two conventional terminals when the AC power cable is disconnected from the male receptacle of the PSU power source, the two sensing terminals are not tightly coupled when disconnected, but the conventional terminals remain on. The power supply equipment can sense whether the AC power cable is tightly connected with the male socket of the PSU power supply or not by detecting whether the two detection ends are tightly connected, and immediately send information to the maintenance system for reporting and early warning. And the shorter the first detection end is, the more timely and more accurate the power supply equipment judges the gradual separation between the AC power cable and the male socket of the PSU power supply, and the problem of the gradual separation between the AC power cable and the male socket of the PSU power supply is discovered as early as possible. The conventional terminal still keeps on, so that power interruption of equipment of the data center is not caused, after an associated operation and maintenance personnel receives an alarm, the problem that the AC power cable and the male socket of the PSU power are slowly separated can be timely known, the problem that the AC power cable and the male socket of the PSU power are slowly separated is timely improved or solved by a follow-up arrangement response scheme, the power supply reliability of the equipment of the data center is improved, the problem that the cable on the physical structure layer is poor in contact or is slowly separated is solved by input detection on the electrical layer, and the stability and the practicability of power supply of a data center machine room are enhanced.

For the same reason, if the second regular end and the second detecting end are in convex shapes, the first regular end and the first detecting end are in concave shapes, so that the second regular end and the second detecting end can be matched with each other. The length of the second detecting end is smaller than that of the second conventional end, and the length of the second conventional end is equal to the depth of the concave of the first conventional end and the first detecting end.

Through the arrangement mode, the system for detecting the power line in place can timely detect whether the contact between the AC power cable and the male socket of the PSU power supply is bad or not, fool-proofing is achieved through the power supply structure and the power supply principle of the power supply equipment, and whether hundred percent coupling and plugging between the AC power cable and the male socket of the PSU power supply are achieved or not can be timely confirmed; and judging whether the problem of slow detachment occurs between the AC power cable and the male socket of the PSU power supply in time. The system can provide information to the maintenance system in time for reporting and early warning, so that the direct disconnection of power supply is avoided, and the problems of downtime, data loss, file damage, equipment damage and the like of equipment in the data center are not caused. The system for detecting the power line in place improves the power supply reliability of equipment of the data center, performs input detection on an electrical level, recognizes the problem of poor contact or slow separation of cables on a physical structure level, and enhances the stability and practicability of power supply of a data center machine room.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The inventor finds that at present, the data center is mainly used for distributing power to the PSU (Power supply unit power module) of a server or a switch device by connecting an AC (Alternating Current alternating Current) power line with a PDU (Power Distribution Unit power distribution unit) and supplying the power input by AC or DC (Direct Current) to the PSU (Power supply unit power module), and common ICT (information and communications technology information communication technology) equipment adopts an N+N redundant power supply design, so that the power supply stability is ensured. The problem that the AC power cable falls off and is not plugged in often occurs in the data center. The current solution to this problem is to physically fix the cable tie or velcro by means of an AC power cord and a male socket of the PSU power supply. However, the following problems still remain with this solution:

The two problems are mainly caused by the fact that the specific structures of the AC power line and the male socket of the PSU power supply cannot enable the power supply equipment to timely detect whether poor contact between the AC power line and the male socket of the PSU power supply is sensed, foolproof is achieved through the power supply structure and the power supply principle of the power supply equipment, and whether hundred percent coupling and plugging between the AC power line and the male socket of the PSU power supply are achieved cannot be timely confirmed; and the problem of slow detachment between the AC power cable and the male receptacle of the PSU power source cannot be timely determined. Referring to fig. 1, a specific structure of the male receptacle of the current AC power cable and PSU power is shown.

It should be noted that, in general, the male socket of the PSU power supply is connected to the PSU of the power supply module of each device, and most of the power supply modules are in an integral structure at present, and when in use, a user usually inserts the power supply module into the male socket of the PSU power supply with an AC power cord. Most of the existing data center devices are designed in a pin shape, namely a convex shape, of a live wire end L, a zero wire end N and a ground end GND in a male socket of a PSU power supply, and are designed in a concave shape, namely a groove corresponding to the pin shape, of an AC power supply line. In fig. 1, for specifically showing the structures of the two, the structure of the contact pin is specifically illustrated by taking a conical body at the front end and a cuboid structure at the rear end as examples, the corresponding groove is also rectangular in cross section with visible leakage, and the corresponding conical body is arranged at the inner bottom end. In practical applications, there are also cylindrical pins, triangular pins, etc., which are not described in detail.

In addition, because the structures of the AC power line and the male socket of the PSU power supply are just matched with each other, the structures of the AC power line and the PSU power supply can be mutually exchanged, namely, the live wire end L, the zero wire end N and the ground end GND in the AC power line are designed to be in a pin shape, namely, are in a convex shape, and the corresponding live wire end L, the zero wire end N and the ground end GND in the male socket of the PSU power supply are designed to be grooves corresponding to the pin shape, namely, are in a concave shape. The structure shown in fig. 1 can be easily obtained by a person skilled in the art, wherein the live wire end L, the neutral wire end N and the ground end GND in the AC power line are designed to be in the shape of pins, and the structure corresponding to the live wire end L, the neutral wire end N and the ground end GND in the male socket of the PSU power supply is designed to be corresponding to the grooves in the shape of pins, and the illustration and explanation of the drawings are omitted.

Because the live wire end L, the zero wire end N and the ground end GND are used for providing electric energy for a power supply in the power supply module, a current loop can be formed as long as the live wire end L, the zero wire end N and the ground end GND of the AC power supply wire and the male socket of the PSU power supply are respectively contacted, the electric energy provided by the PDU is transmitted to the power supply through the live wire end L, and the power supply starts to work to provide electric energy for equipment. The two are only completely disconnected at the live wire end L, the zero wire end N and the ground end GND, and when the two ends are not contacted, the power supply equipment can be powered off, namely, the power supply equipment only has two states: the live wire end L, the zero wire end N and the ground end GND of the AC power line and the male socket of the PSU power supply are respectively contacted with each other, and the power supply equipment is powered to work normally; the live wire end L, the zero wire end N and the ground end GND of the AC power line and the male socket of the PSU power supply are not contacted, and the power supply equipment is not powered and cannot work normally. The power supply device cannot sense whether the current contact between the AC power cord and the male receptacle of the PSU power supply is poor, and cannot sense whether hundred percent of coupling plug-in tightness is achieved between the AC power cord and the male receptacle of the PSU power supply. It will be appreciated that when the problem of slow disengagement occurs between the AC power cord and the male receptacle of the PSU power source, the power supply device is still powered, which certainly cannot judge the situation of slow disengagement between the AC power cord and the male receptacle of the PSU power source in time, since the live end L, the neutral end N, and the ground end GND of both the AC power cord and the male receptacle of the PSU power source may remain in contact.

Aiming at the problems, how to timely detect whether the contact between the AC power cable and the male socket of the PSU power supply is bad, and how to timely confirm whether hundred percent of coupling and plugging between the AC power cable and the male socket of the PSU power supply is achieved by the power supply structure and the power supply principle of the power supply equipment; and how to judge whether the problem of slow detachment occurs between the AC power cable and the male socket of the PSU power source in time, the inventors creatively propose the system for detecting the presence of the power line of the present invention, and the system for detecting the presence of the power line of the present invention is explained and illustrated in detail below.

The system for detecting the in-place of the power line provided by the invention comprises the following components: a power cord and a power outlet, the power cord configured to be plugged into the power outlet; the power end male socket includes: a first regular end and a first detection end; the power cord includes: a second conventional end and a second detection end. The conventional terminal provided by the present invention can be understood as the structure already existing on the power cord and the power terminal male socket, for example, as shown in fig. 1: a live wire end L, a null wire end N, a ground end GND, etc.; the detection end is a structure which is not provided on the prior power line and the prior power end male socket, and is invented by the invention.

In the structure, the power line and the power end male socket are just matched with each other, so that the structures of the power line and the power end male socket can be mutually interchanged. If the first regular end and the first detection end are in a convex shape, the second regular end and the second detection end are in a concave shape, the length of the first detection end is smaller than that of the first regular end, and the length of the first regular end is equal to the depth of each of the second regular end and the second detection end. The structure can be more intuitively understood by referring to the schematic structural diagram of the power line detection in-situ system provided by the invention shown in fig. 2.

In fig. 2, the first normal terminal on the male power socket is the live terminal L, the neutral terminal N, and the ground terminal GND, and the first detection terminal is defined as Psin. It should be noted that, the position of the first detection terminal Psin is only an exemplary position, and does not represent that the first detection terminal Psin can only be disposed at this position, and in practical application, the first detection terminal Psin may be disposed at any position on the power supply terminal male socket according to requirements. The position of the first detection end Psin is provided with a second conventional end and a second detection end, namely: the second normal end is a live wire end L, a zero wire end N and a ground end GND, the second detection end is Psin, and the difference is that a groove with a corresponding contact pin shape structure is formed on the power wire. It will be appreciated that the positions of the first and second detection ends need to correspond, otherwise the pins of the first detection end Psin cannot be insertedly coupled with the grooves of the second detection end Psin.

As described above, the structures of the power cord and the power terminal male socket can be interchanged, so if the second regular terminal and the second detecting terminal are in convex shapes, the first regular terminal and the first detecting terminal are in concave shapes, and the length of the second detecting terminal is smaller than that of the second regular terminal, and the length of the second regular terminal is equal to the respective concave depths of the first regular terminal and the first detecting terminal. Referring to the structure shown in fig. 2, a person skilled in the art can easily obtain a structure that a live wire end L, a neutral wire end N, a ground end GND and a second detection end Psin in an AC power line are designed to be in a pin shape, and a structure that a corresponding live wire end L, a neutral wire end N, a ground end GND and a first detection end Psin in a power supply male socket are designed to be in a groove corresponding to the pin shape, which is not illustrated and explained in the drawings.

Based on the above-described structure, the structure shown in fig. 2 is explained and explained in the following. The depth of the groove of the second detection end Psin on the power line is the same as the depth of the grooves of the live wire end L and the zero wire end N. The depth of the groove of the ground end GND is generally greater than the depths of the grooves of the live wire end L and the neutral wire end N, and the depths of the grooves of the ground end GND and the grooves of the live wire end L and the neutral wire end N on a part of the power wire are also the same, but no matter what kind of groove depth structure is adopted, the depths of the grooves of the second detection end Psin and the grooves of the live wire end L and the neutral wire end N are required to be ensured to be the same.

The length of the pin of the first detecting end Psin on the male socket of the power end is smaller than that of the pins of the live wire end L and the zero wire end N. In general, the length of the ground end GND pin is greater than the length of the live wire end L and the neutral wire end N pin, and the depth of the ground end GND groove corresponding to the ground end GND pin is naturally greater than the depth of the live wire end L and the neutral wire end N groove, but the length of the ground end GND pin on the male socket of the power supply end is still the same as the length of the live wire end L and the neutral wire end N pin, however, no matter what pin length is, the length of the first detection end Psin pin needs to be ensured to be smaller than the length of the live wire end L and the neutral wire end N pin.

The reason for this design is: in order to ensure that the first detection terminal Psin on the male power terminal socket and the second detection terminal Psin on the power cord are tightly coupled after the two conventional terminals are tightly coupled, this can be intuitively understood by the structure shown in fig. 2. Because the length of each contact pin of the live wire end L, the zero wire end N and the ground end GND on the power supply end male socket is larger than that of the first detection end Psin, in the process of inserting the power supply wire into the power supply end male socket, the live wire end L, the zero wire end N and the ground end GND of the power supply end male socket are definitely contacted first and then are tightly inserted and coupled, and the detection ends of the power supply end male socket and the ground end GND of the power supply end male socket are tightly inserted and coupled at last because of the short length of the contact pin of the first detection end Psin, the detection ends Psin of the power supply end male socket are contacted last. Thus, if the two detection terminals Psin are tightly coupled, the two normal terminals, namely the live wire terminal L, the neutral wire terminal N, and the ground terminal GND, must also be tightly coupled.

Therefore, the PSU can sense whether the contact between the power line and the power male socket of the PSU is bad after the power line is inserted into the power male socket by detecting whether the two detection ends Psin are tightly inserted and coupled, and if the contact is bad, the PSU can immediately send information to a maintenance system for reporting and early warning. And if the first detection end Psin is shorter, the PSU is more accurate to judge whether hundred percent coupling plugging is achieved between the power line and the power end male socket of the PSU.

In addition, after a period of use, when the conditions of splitting, breaking and the like occur in the wire harness buckle or the magic tape or the conditions of splitting, breaking and the like do not occur in the wire harness buckle or the magic tape because of external factors or external forces and the like, but the problem that the power line and the power supply end male socket of the PSU are separated slowly due to poor contact caused by other factors and abnormal occurrence is solved well. Because the two detection terminals Psin must be disconnected before the two normal terminals, i.e. before the live terminal L, the neutral terminal N, and the ground terminal GND, when the two detection terminals Psin are disconnected, the two detection terminals are not tightly coupled, but the live terminal L, the neutral terminal N, and the ground terminal GND of the normal terminals remain in a conductive state. The PSU can sense after the power line and the power end male socket of the PSU are slowly separated by detecting whether the two detection ends Psin are tightly inserted and coupled, and the PSU can immediately send information to a maintenance system for reporting and early warning. And the shorter the first detection end Psin is, the more timely and more accurate the PSU judges the gradual separation between the power line and the power end male socket of the PSU, and the problem of the gradual separation between the power line and the power end male socket of the PSU is discovered as early as possible.

In a preferred embodiment, if the first normal-end live wire end L, the neutral wire end N, the ground end GND and the first detection end Psin are in a convex shape, the second normal-end live wire end L, the neutral wire end N, the ground end GND and the second detection end Psin are in a concave shape, and the length of the first detection end Psin is a half of the length of the first normal end. If the length of the ground end GND is greater than the live end L and the neutral end N, there is a size relationship: length of the first detection end Psin pin 3=length of the live wire L pin on the power end male socket=length of the neutral wire N pin on the power end male socket=depth of the second detection end Psin groove=depth of the live wire L groove on the power wire=depth of the neutral wire N groove on the power wire < length of the ground end GND on the power end male socket=length of the ground end GND groove on the power wire.

The length of the first detection end Psin is designed to be a third of the length of the first conventional end instead of being shorter, because although the length of the first detection end Psin is shorter, the PSU is more favorable for accurately confirming whether hundred percent coupling and plugging are achieved between the power line and the power male socket of the PSU, and is more favorable for timely and accurately judging the problem that the power line and the power male socket of the PSU are slowly separated, but if the length of the first detection end Psin is too short, the problem that misjudgment or inaccurate judgment is likely to be caused, and the problem is brought about, instead, the length of the first detection end Psin is designed to be a third of the length of the first conventional end, so that a better choice is to design the length of the first detection end Psin to be a second third of the length of the first conventional end. It will be understood, of course, that the length of the detection end Psin may be designed according to the requirements in practical applications. Referring to fig. 3, the lengths of the respective ends are exemplarily shown by taking the length of the first detection end Psin as a third of the length of the first normal end and the length of the ground end GND is longest as an example, and it can be intuitively known from fig. 3 that the length of the detection end Psin is shortest.

Further, similarly to the foregoing, if the second normal-end live wire end L, neutral wire end N, ground end GND and second detection end Psin are in a convex shape, the first normal-end live wire end L, neutral wire end N, ground end GND and first detection end Psin are in a concave shape, and then the length of the second detection end Psin must be three-half of the length of the second normal end.

In a preferred embodiment, since the power module PSU is connected to the power outlet male socket or is integral with the power outlet male socket, the power module PSU is configured to determine whether to issue an alarm message and to control whether its own power supply is powered based on whether the first and second detection terminals Psin and Psin are tightly coupled.

In a preferred embodiment, a circuit configuration of the preferred power module is shown in fig. 4. The power module includes: diode D, pull-up resistor R, MOS, Q7D, and MCU. In fig. 4, for better explaining the power module structure, a BMC (Baseboard Management Controller basic management controller) is also shown, and the MCU and the BMC communicate through the IIC bus. In fig. 4, psin# represents a first detection terminal Psin in the power supply terminal male socket, psin represents a second detection terminal Psin in the power supply line, and the second detection terminal Psin is grounded GND.

The cathode of the diode D is connected with a first detection end Psin#; the anode of the diode D is connected with the first end of the pull-up resistor R and the grid electrode of the MOS tube Q7D; the second terminal of the pull-up resistor R receives the pull-up voltage 3.3VS.

The source electrode of the MOS tube Q7D is grounded to GND, and the drain electrode of the MOS tube Q7D is connected with an input signal pin MCU in of the MCU.

Based on the structure of the power supply module, the working principle is as follows:

in the process of inserting the power line into the power supply end male socket, if the second detection end Psin and the first detection end Psin# are not tightly coupled, namely are not in contact with each other, then Psin# is normally 3.3V and is pulled up to a high level and connected to the grid electrode of the MOS tube Q7D, so that the MOS tube Q7D is conducted, at the moment, a signal of a MUC in pin in the MUC is pulled to the ground GND, when the MCU detects that the Mcu in pin is in a low level, the MCU can close the power output, power input power supply abnormality information is reported to the BMC through the IIC bus, and meanwhile, the power supply indicates that the fault lamp is on. In general, the BMC reports the power supply input power supply abnormality information to the machine room operation and maintenance department, and finally the machine room operation and maintenance is processed.

And in the normal operation process of the power supply, the second detection end Psin and the first detection end Psin# are kept in a contact state, the 3.3V pull-up level received by the Psin# is pulled to the ground GND, the MOS tube Q7D is not conducted, the signal of the MCU in the MUC is in a high level, when the MCU detects that the Mcu in pin is in the high level, the power supply output is started, and the power supply input power supply normal information is reported to the BMC through the IIC bus.

When the power supply is in the normal operation process, the conditions of splitting, breaking and the like of the wire harness buckle or the magic tape are caused by external factors or external forces and the like, or the conditions of splitting, breaking and the like of the wire harness buckle or the magic tape are not caused, but the poor contact between the power supply wire and the power supply end male socket of the PSU is caused by other factors, and the abnormal contact between the power supply wire and the power supply end male socket of the PSU is caused, the second detection end Psin and the first detection end Psin# can be disconnected firstly, under the condition, psin# becomes 3.3V to be pulled up to a high level again, and is connected to the grid electrode of the MOS tube Q7D, so that the MOS tube Q7D is conducted, at the moment, the signal of the MUC in pin in MUC is pulled to the ground GND again, when the MCU detects that the Mcu in pin becomes a low level, the power supply output is not turned off, and normal power supply of equipment is ensured, but the MCU reports power supply abnormal power supply information to the BMC through the IIC bus, and simultaneously the power supply indication fault lamp flashes. In general, the BMC reports the power supply input power supply abnormality information to the machine room operation and maintenance department, and finally the machine room operation and maintenance is processed.

Based on the structure of the power line and the power end male socket, in the process of inserting the power line into the power end male socket, after the first conventional end live wire end L, the zero wire end N and the ground end GND are tightly inserted and coupled with the second conventional end live wire end L, the zero wire end N and the ground end GND, the first detection end Psin and the second detection end Psin are tightly inserted and coupled again, the power module PSU does not send alarm information to an upper server or an operation and maintenance system, and the PSU controls the power supply to be powered through the first conventional end live wire end L, the zero wire end N, the ground end GND, the second conventional end live wire end L, the zero wire end N and the ground end GND, so that the power line and the power end male socket are tightly inserted and coupled and are in a state during normal operation.

If the first normal end live wire end L, the zero line end N and the ground end GND are tightly inserted and coupled with the second normal end live wire end L, the zero line end N and the ground end GND, and then the first detection end Psin and the second detection end Psin are not tightly inserted and coupled, the power module PSU sends alarm information to an upper server or an operation and maintenance system, and the PSU controls the power supply not to be powered. This is the state when the power cord and the power outlet are not plugged into each other in a tight manner, and there is a possibility of a bad contact, and in this state, the PSU controls the power supply not to receive power for safety.

For another case: after the power supply is powered on, that is, the device is already in a powered-on state, if the first detection terminal Psin and the second detection terminal Psin are in a disconnected state, the problem that the power supply line and the power supply terminal male socket are gradually separated from each other possibly caused by various factors between the power supply line and the power supply terminal male socket of the PSU is indicated, at this time, the PSU sends alarm information to an upper-level server or an operation and maintenance system, but at this time, the PSU does not control the power supply to be not powered on, but controls the power supply to still keep powered on through the first conventional terminal fire wire end L, the zero wire end N, the ground terminal GND and the second conventional terminal fire wire end L, the zero wire end N and the ground terminal GND. Because the problem that the power line and the power end male socket are slowly separated at this time is solved, but the first conventional end live wire end L, the zero wire end N, the ground end GND and the second conventional end live wire end L, the zero wire end N and the ground end GND are still in a connection state, electric energy can still be transmitted to the power supply through the first conventional end live wire end L, the zero wire end N, the ground end GND and the second conventional end live wire end L, the zero wire end N and the ground end GND, and in order to ensure the stable operation of the equipment, alarm information can be sent out first, so that relevant operation and maintenance personnel can timely and accurately know the current situation, and a corresponding scheme is further arranged at a proper time to timely improve or solve the problem that the power line and the power end male socket of the PSU are slowly separated.

In the design of the structure, an alarm indicator lamp can be additionally arranged on the PSU of the power supply module, and when the problem of poor contact or loose coupling or slow detachment occurs between the power supply line and the power supply end male socket, the alarm can be displayed and displayed more intuitively through the alarm indicator lamp, so that the problem of related operation and maintenance personnel can be timely reminded in a more-dimensional mode.

In the practical floor application, the above structure may set a plurality of modules in the power module PSU, and cooperate with the whole detection flow, for example, refer to a possible module and flow collocation schematic diagram shown in fig. 5. The module in fig. 5 includes: the device comprises a power-on judging module, an input detecting module, a power judging module, a power processing module, a power alarm fault reporting module and an executing module.

After the process is started, the power-on judging module judges whether the power is in a power-on state or not, and if not, the external input line (namely the power line) needs to be plugged into the power-end male socket. The input Psin (namely a first detection end and a second detection end) is detected in place by an input detection module; and judging whether the Psin is in place or not by the power supply judging module.

If so, continuing the power supply to be powered on or keeping the power-on operation. If not, the power processing module sends a shutdown signal or controls the power inside not to be shutdown. And then the power supply alarm fault reporting module reports the abnormal alarm of the input line. The operation and maintenance personnel can then utilize the execution module to discharge the input fault.

In addition, it should be noted that, the foregoing is based on the explanation and explanation of the conventional power cord and power socket models C13 and C14, and in practical application, other models of power cord and power socket, for example: and C19, C20 and the like can be also suitable for the system for detecting the power line in place, and the specific application of other types can be obtained by simple deduction on the basis of the system for detecting the power line in place.

The system for detecting the on-site of the power line provided by the invention can timely detect whether the contact between the AC power cable and the male socket of the PSU power supply is bad or not, and can timely confirm whether hundred percent coupling and plugging are achieved or not by the power supply structure and the power supply principle of the power supply equipment; and judging whether the problem of slow detachment occurs between the AC power cable and the male socket of the PSU power supply in time. The system can provide information to the maintenance system in time for reporting and early warning, so that the direct disconnection of power supply is avoided, and the problems of downtime, data loss, file damage, equipment damage and the like of equipment in the data center are not caused. The system for detecting the power line in place improves the power supply reliability of equipment of the data center, performs input detection on an electrical level, recognizes the problem of poor contact or slow separation of cables on a physical structure level, and enhances the stability and practicability of power supply of a data center machine room.

Based on the above system for detecting the presence of the power line, the present invention further provides a method for detecting the presence of the power line, and refer to a flowchart of a method for detecting the presence of the power line shown in fig. 6. The method is applied to the system for detecting the in-place of the power line, and the system for detecting the in-place of the power line comprises the following steps: a power cord and a power outlet, the power cord configured to be plugged into the power outlet.

The power end male socket includes: a first regular end and a first detection end; the power cord includes: a second regular end and a second detection end; the method comprises the following steps:

step 601: detecting whether the first detection end and the second detection end are tightly coupled;

step 602: and determining whether alarm information is sent out or not and whether a control power supply is powered through the first conventional end and the second conventional end or not according to the condition of tight plug coupling between the first detection end and the second detection end.

Optionally, step 602 specifically includes:

The foregoing structural parts have been explained and illustrated in detail, and reference may be made to the foregoing parts for brevity and no further explanation is provided.

Based on the system for detecting the presence of the power line, the embodiment of the invention also provides electronic equipment, which comprises the system for detecting the presence of the power line.

By way of example, the system for detecting the presence of a power line provided by the present invention comprises: a power cord and a power outlet, the power cord configured to be plugged into the power outlet; the power end male socket includes: a first regular end and a first detection end; the power cord includes: a second conventional end and a second detection end. By conventional terminal is understood the structure that is already present on the power cord and the power terminal male socket, for example: a live wire L end, a zero wire N end, a ground GND end and the like; the detection end is a structure which is not provided on the prior power line and the prior power end male socket, and is invented by the invention.

The reason for this design is: in order to ensure that the first and second sensing terminals are tightly coupled after the two conventional terminals are tightly coupled, and since the length of the first sensing terminal is smaller than that of the conventional terminal, if the two sensing terminals are tightly coupled, the two conventional terminals are also positively tightly coupled. Therefore, the power supply equipment can sense whether the contact between the AC power cable and the male socket of the PSU power supply is bad after the AC power cable is inserted into the male socket of the PSU power supply by detecting whether the two detection ends are tightly inserted and coupled, and can immediately send information to a maintenance system for reporting and early warning. And the shorter the first detection end, the more accurate the power supply device will be to confirm whether one hundred percent coupling is achieved between the AC power cable and the male receptacle of the PSU power source.
