Background
With the development of the big data era, data centers are increasingly important in social development, and the power supply safety level of a data machine room is higher and higher. The national standard (GB 50174-2008) A-level machine room or the international standard TIA-942Tier3 and above are designed to be connected with a two-way different mains supply (2N system power supply, general power supply voltage level 10KV) system for power supply. The data computer room is additionally provided with a self-contained power supply (such as a diesel generator set) so as to be connected with power supply. However, the power supply reliability of the utility power system is affected by uncontrollable natural conditions such as external natural disasters and equipment failures, so that sudden power failure occurs.
The design requirement of the data computer room is that when one path of the commercial power system is powered off, the commercial power system is automatically switched to another path of the power supply system through the interconnection switch to supply power. When the two power supply systems are powered off, the diesel generator set can be started by a self-contained power supply such as the diesel generator set, and the diesel generator set can supply power quickly. In order to ensure the running safety of the city power supply system, when the two power supply systems are powered off, the supplied network needs to be switched to the diesel generator side in a manual operation mode, so that the normal power supply of the supplied network is recovered through the diesel generator, and the diesel generator set is prevented from transmitting power backwards to the city power supply system.
For the situation that two power supply systems exist, when the two power supply systems stop supplying power, the equipment switch in the supplied network corresponding to the power supply system which is powered off later is in a closed state, part of the equipment switch in the supplied network corresponding to the power supply system which is powered off first is in an open state, and the equipment switch is generally set to have the function of automatic switching but not automatic recovery. Generally, operation and maintenance personnel cannot accurately determine the power failure sequence of the two power supply systems, so that when the two powered networks are restored to be powered on, the powered networks in a connected state (namely, the powered networks corresponding to the one powered system which is powered off later) cannot be restored to be powered on timely due to the fact that the powered networks corresponding to the power supply systems which are powered off first are restored preferentially, and therefore the efficiency of restoring the power to be powered on of the powered networks is low.
In view of the above, there is a need for an improved dual power supply system in the prior art to solve the above problems.

Generally, when one municipal power supply system is powered off and automatically switched to another municipal power supply system, or when two municipal power supply systems are powered off and manually switched to the diesel generator side for power supply, in the process of automatic switching or manual switching of a switch, core equipment of a data room is uninterruptedly supported by an Uninterruptible Power Supply (UPS), and if the diesel generator is not started quickly or the municipal power supply system is recovered to supply power to a supplied network, all power supply systems in the data room are interrupted, so that the normal operation of a service is influenced.
When the operation and maintenance personnel electrify the pre-recovered supplied network under the condition that the power failure sequence of the two power supply systems is not determined, the supplied network corresponding to the power supply system with the power failure firstly may be recovered preferentially (namely, the supplied network corresponding to the power supply system with the power failure firstly is communicated with the diesel generator set preferentially, and the supplied network cannot recover the power immediately when the power supply to the supplied network is recovered due to the fact that a part of equipment switches in the supplied network are in a switching-off state), and the supplied network corresponding to the important one-path power supply system (namely, the supplied network corresponding to the power supply system with the power failure later is recovered immediately when the power supply to the supplied network is recovered due to the fact that the equipment switches are in a switching-on state) is not recovered preferentially. Therefore, since the supplied network corresponding to the power supply system that is restored preferentially cannot be immediately energized, it is necessary to manually close the device switch in the supplied network corresponding to the power supply system that has been powered off first and that is restored preferentially successfully, which results in a significant reduction in the efficiency of restoring the energization of the supplied network due to the delay in the manual switching time. Moreover, when the supplied network is large, the manual power restoration method further reduces the power restoration efficiency due to insufficient agility of the response, and even interrupts all power supply systems in the data room due to untimely power supply of the supplied network.

For example, the close indication mark may be a text mark such as "close" or "on" to indicate that the corresponding first switch or second switch is in the closing state (or the operating state), and the open indication mark may be a text mark such as "open" or "off" to indicate that the corresponding first switch or second switch is in the opening state (or the closing state).

Because the first switch 11 and the second switch 12 are both provided with the closing indication signs for indicating that the switches are in the closing state, when both the two power supply systems stop supplying power, the first switch 11 corresponding to the first power supply system which is powered off first does not display the closing indication sign 112 to the user because the first switch is in the opening state, and the second switch 12 corresponding to the second power supply system 22 which is powered off then displays the closing indication sign 122 to the user because the second switch is still in the closing state. Therefore, after the two-way power supply system stops supplying power, the user can accurately and quickly determine the power failure sequence of the two-way power supply system based on whether the closing indication mark is displayed on the first switch 11 or the second switch 12. The user preferentially recovers the electrification of the supplied network corresponding to the power supply system with the power failure after the power failure according to the determined power failure sequence of the two power supply systems (namely preferentially enabling the supplied network corresponding to the power supply system with the power failure after the power failure to be communicated with the diesel generator set), so that the electrification of the supplied network corresponding to the power supply system with the power failure after the power failure can be directly recovered, and the normal electrification of the important supplied network can be further recovered in place. Therefore, the efficiency of recovering the power supply of an important path by the power supply network can be effectively improved, and the influence on the normal operation of the service due to the interruption of all power supply systems in the data machine room caused by the untimely power supply of the power supply network is prevented.
