[0046] In order to make the person skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments.

For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0049] In the existing UPS (Uninterruptible Power System, uninterruptible power supply) system, the bypass input of the UPS and the input end of the UPS are connected to the mains, which are easy to be connected to the same system; however, the system of the bypass end of the UPS and the output end of the UPS should be the same, when the bypass system of the UPS and the output system of the UPS are different, it is easy to cause the system wiring error of the UPS, and then it is most likely to cause the mains voltage abnormality, output short circuit and other faults, and even cause the machine to fail, thereby reducing the safety of the UPS system. Therefore, the embodiments of the present application provide a system detection method, which can accurately detect whether the system wiring error occurs, and improve the safety of the UPS, as shown in Figure 1 The specific steps include steps 101 to 103.
[0050] 101, after connecting the mains to the bypass end of the UPS, detecting the mains information connected to the bypass end, and determining the bypass system of the bypass end.
[0051] In the embodiments of the present application, when the system of the UPS is detected, the bypass end of the UPS needs to be connected to the mains (alternating current), as shown in Figure 2 In the figure, the mains connected to the input end is represented by A phase, B phase and C phase, the mains connected to the bypass end is represented by U phase, V phase and W phase, and the three-phase output end of the UPS is A', B' and C'. After the mains is powered on, it is necessary to determine that the connected mains is normal, and to provide conditions for system detection. Among them, the normality of the connected mains can be determined by judging the amplitude and frequency of the connected mains; if the amplitude and frequency of the mains are normal, it is considered that the connected mains is normal, and then the system of the UPS is detected.
[0052] In the working process of the UPS, if the mains connected to the input end of the UPS is normal, the mains connected to the input end of the UPS is converted through an AC-DC rectifier (alternating current-direct current) and then converted through a DC-AC inverter (direct current-alternating current) to output alternating current required by the electrical equipment; if the mains connected to the input end of the UPS is abnormal, the mains is directly connected to the bypass end of the UPS through a bypass switch to provide the required alternating current for the electrical equipment.
[0053] The bypass mode of the UPS is a working state without rectification and inversion in the UPS. The bypass mode of the UPS is a backup output after inversion. In general, the bypass system of the UPS is the same as the output system of the UPS. In order to determine the output system required by the user, it is necessary to detect the bypass system of the UPS. The bypass system of the bypass end can be determined by detecting the mains information connected to the bypass end, that is, the bypass system is the mains system connected to the bypass end.
[0054] Specifically, the detection process of the bypass system can be that, in a preset phase of the mains, a voltage difference between the preset phase and other phases of the mains is detected; and the bypass system of the bypass end is determined based on the voltage difference. The instantaneous detection point can be a zero-crossing point position or a peak value of the preset phase connected to the bypass end, which is not limited here; the preset phase is any one of U phase, V phase and W phase, and the other phase is a phase other than the preset phase of the mains; and whether the bypass system of the bypass end is single-phase connection or three-phase connection can be determined by the size of the voltage difference.
[0055] When the instantaneous detection point is the zero-crossing point position of the preset phase, it can be determined whether the voltage difference between the preset phase and the other phase in the zero-crossing point position is less than a preset voltage threshold; if yes, it is determined that the bypass system of the bypass end is single-phase connection (single-phase system); if no, it is determined that the bypass system of the bypass end is three-phase connection (three-phase system). It can be understood that the other phase can be one phase or two phases, that is, the UV phase voltage difference can be detected, or the UV phase voltage difference and the UW phase voltage difference can be detected. For example, the UV phase voltage difference and the UW phase voltage difference can be detected at the zero-crossing point of the U phase. The zero-crossing point position can be determined by phase locking or capture, which is not limited here. For the selection of the preset voltage threshold, when the bypass system is single-phase connection, the voltages of the three phases are consistent or close to consistent, so the preset voltage threshold should not be too large and can be set to 0V or 1V, which is not limited here. Preferably, the preset voltage threshold is set to 0V. When the voltages of the three phases are consistent, that is, the waveforms of the three-phase voltages of the bypass end overlap, it is determined that the bypass system is single-phase system. When the voltages of the three phases are inconsistent, that is, the waveforms of the three-phase voltages of the bypass end do not overlap, it is determined that the bypass system is three-phase system.
[0056] It can be understood that when the bypass end is compatible with three-phase wiring and single-phase wiring, the three live line terminals of the bypass end are connected to the power supply. At this time, when the three live line terminals are connected to the same power supply, i.e., the voltages of the three phases are consistent, it can be determined to be a single-phase system. When the three live line terminals are connected to different power supplies, i.e., the voltages of the three phases are inconsistent, it can be determined to be a three-phase system. When the load connected to the bypass end is light, only one live line terminal of the bypass end is connected to the power supply, i.e., when the load is light, only one phase of the bypass end is connected to the power supply, and the other two phases are not connected to the power supply. At this time, when the voltages of the three phases of the bypass end are consistent, it can also be determined to be a single-phase system.
[0057] Further, when the instantaneous detection point is a non-zero-crossing point of the preset phase, it can also be determined whether the voltage difference between the preset phase and other phases is less than a preset threshold value, and then the bypass system is determined. However, at the non-zero-crossing point, such as the peak or valley of the preset phase, when the bypass system is a three-phase system, there is a crossing point between the voltage waveforms of two phases. Therefore, at the non-zero-crossing point of the preset phase, if the voltage values of any two phases are the same, it is determined whether the voltage difference between the two phases and the third phase is less than a preset voltage threshold value. If yes, it is determined that the bypass system of the bypass end is single-phase wiring. If no, it is determined that the bypass system of the bypass end is three-phase wiring. If the voltage values of the U phase and the V phase are the same, it is determined whether the voltage difference between the U phase and the W phase and the voltage difference between the V phase and the V phase are less than a preset voltage threshold value. If both voltage differences are less than the preset voltage threshold value, it is determined that the bypass system of the bypass end is single-phase wiring. If both voltage differences are greater than the preset voltage threshold value, it is determined that the bypass system of the bypass end is three-phase wiring.
[0058] 102. Invert enable any one phase output of the UPS, detect the output voltage of the three-phase output of the UPS, and determine the output system of the UPS.
[0059] After the input end of the UPS is connected to the power supply, the output end of the UPS can be detected, i.e., the output system is detected. Any one phase output of the UPS can be invert enabled, and after inversion, the output voltage of the three-phase output of the UPS is detected to determine the output system of the UPS. It can be understood that the structure corresponding to the three-phase output of the UPS is in the form of three parallel connections, i.e., the input and output of each phase are independently performed on the internal structure of the UPS, i.e., the output end of each phase is invert enabled by a separate inverter, which can be a Hall effect relay (HALL) corresponding to the output end. Any one phase output corresponding to the inverter can be debugged to invert enable, i.e., the Hall effect relay is turned to the inverting state, and the other two phase output ends are not invert enabled. That is, the inverter can be invert enabled at the output end of the UPS to generate controllable alternating current at the output end, so as to facilitate output system detection.
[0060] After inverting enable is performed on any one phase output end of the UPS, the output voltage of the three-phase output end of the UPS can be detected. If the output voltages of the three-phase output end of the UPS are consistent, i.e., the waveforms of the A', B' and C' output voltages are the same, it is determined that the output mode of the UPS is single-phase wiring. If only the output end with inverting enable has an output voltage, it is determined that the output mode of the UPS is three-phase wiring. That is, when the output voltages of the three-phase output end of the UPS are inconsistent, the other two phase output ends can be separately inverting enabled. If only the output end with inverting enable has an output voltage, it is determined that the output mode of the UPS is three-phase wiring.
[0061] It can be understood that the execution sequence of the step 101 and the step 102 is not limited here, i.e., the bypass mode detection can be performed first, or the output mode detection can be performed first.
[0062] 103. Comparing the bypass mode with the output mode to determine whether the UPS has wiring error.
[0063] After the bypass mode of the bypass end of the UPS and the output mode of the output end of the UPS are determined, the bypass mode can be compared with the output mode to determine whether the UPS has wiring error. Specifically, if the bypass mode is consistent with the output mode, e.g., when the bypass mode is single-phase wiring and the output mode is also single-phase wiring, it is determined that the output mode of the UPS meets the output mode required by the user, and it is determined that the UPS does not have wiring error and can be normally used. If the bypass mode is inconsistent with the output mode, e.g., when the bypass mode is single-phase wiring and the output mode is three-phase wiring, it is determined that the output mode of the UPS does not meet the output mode required by the user, and it is determined that the UPS has wiring error.
[0064] When the bypass mode is inconsistent with the output mode, i.e., it is determined that the UPS has wiring error, the first alarm device can trigger an alarm to remind the user that the UPS has wiring error and needs to be re-wired. It can be understood that the first alarm device can be an audible and visual alarm device or a signal alarm device, and the specific type is not limited here. In this case, the user can correct the bypass mode of the UPS by changing the wiring of the bypass end of the UPS, or correct the output mode of the UPS by changing the wiring of the output end of the UPS, so as to make the bypass mode consistent with the output mode.
[0065] It can be seen that in the embodiment of the application, after the bypass terminal of the UPS is connected to the commercial power, the commercial power information connected to the bypass terminal is detected to determine the bypass mode of the bypass terminal; the inverter enable of any one phase output terminal of the UPS is performed, the output voltage of the three-phase output terminal of the UPS is detected to determine the output mode of the UPS; the bypass mode and the output mode are compared to determine whether the mode wiring error of the UPS occurs. It can be seen that by detecting the bypass mode of the UPS, the bypass mode is the output mode required by the user, and by comparing the bypass mode with the detected output mode of the UPS, whether the mode wiring error occurs can be accurately detected, so that the UPS can be operated without the mode wiring error, and the safety of the UPS is improved.
[0066] In an implementable manner, during the comparison between the bypass mode and the output mode, it can be further determined whether the bypass mode or the output mode has the mode wiring error, so as to rewire the mode with the wiring error.
[0067] In the embodiment of the application, the preset output mode of the UPS can be obtained, and the preset output mode is the output mode set in the UPS system; the UPS system can be set to 11 / 31 mode, that is, the output is single-phase wiring, or 33 mode, that is, the output is three-phase wiring. The bypass mode and the output mode can be compared, and if the bypass mode and the output mode are inconsistent, it indicates that the mode wiring error occurs in the UPS, at this time, the bypass mode and the preset output mode of the UPS can be compared, and the output mode and the preset output mode of the UPS can be compared to determine the mode with the wiring error.
[0068] It can be understood that the mode generally includes two modes of single-phase wiring or three-phase wiring, and at least one of the bypass mode and the output mode is consistent with the preset output mode of the UPS. If the bypass mode is inconsistent with the preset output mode of the UPS, the output mode is consistent with the preset output mode set by the UPS itself, and it is determined that the bypass mode has the wiring error; if the output mode is inconsistent with the preset output mode of the UPS, the bypass mode is consistent with the preset output mode set by the UPS itself, and it is determined that the output mode has the wiring error.
[0069] When it is determined that the bypass mode connection error exists, the bypass output of the UPS is disabled, and the second alarm device is controlled to issue an alarm to remind the user of the bypass terminal connection error of the UPS. In this case, the user can correct the bypass mode error of the UPS by changing the connection of the bypass terminal of the UPS, or change the preset output mode of the UPS and the connection of the output terminal of the UPS, so that the preset output mode, the bypass mode and the output mode are consistent. When it is determined that the output mode connection error exists, the inverter output of the UPS is disabled, and the third alarm device is controlled to issue an alarm to remind the user of the output terminal connection error of the UPS. In this case, the user can correct the output mode error of the UPS by changing the connection of the output terminal of the UPS, or change the preset output mode of the UPS and the connection of the bypass terminal of the UPS, so that the preset output mode, the bypass mode and the output mode are consistent.
[0070] The second alarm device and the third alarm device can be an audible and light alarm device, and the same audible and light alarm device can be selected for the two alarm devices to save costs. Meanwhile, considering that the alarm conditions for triggering the second alarm device and the third alarm device to issue an alarm are different, different audible and light alarms corresponding to different alarm conditions are set to distinguish different alarm conditions, so that the audible and light alarm device corresponding to the alarm condition is controlled to issue an audible and light alarm when any alarm condition is met during the detection of the UPS.
[0071] The embodiment of the present application also provides a mode detection device, as shown in Figure 3 which comprises a bypass mode detection module 301, an output mode detection module 302 and a comparison processing module 303.

[0073] The output mode detection module 302 is connected with the three-phase output terminal of the UPS, and is used to enable the inverter of any one phase output terminal of the UPS, detect the output voltage of the three-phase output terminal of the UPS, and determine the output mode of the UPS.
[0074] The comparison processing module 303 is connected with the bypass mode detection module 301 and the output mode detection module 302 respectively, and is used to compare the bypass mode with the output mode, and determine whether the mode connection error of the UPS exists.
[0075] The embodiment of the present application also provides a mode detection device 400, as shown in Figure 4As shown, the system detection device 400 of the embodiments of the present application can include one or more central processing units (CPUs) 401 and a memory 402 in which one or more application programs or data are stored.
