when the absolute value of the amplitude of the alternating-current voltage waveform is smaller than or equal to a protection threshold value and the duration is longer than or equal to a set maintaining time, judging that the box transformer meets a preset condition;
when the absolute value of the amplitude of the alternating-current voltage waveform is larger than the protection threshold value and the duration is smaller than the set maintaining time, judging that the box transformer does not meet a preset condition;
when the absolute value of the amplitude of the alternating-current voltage waveform is smaller than or equal to the protection threshold value and the duration is smaller than the set maintaining time, judging that the box transformer does not meet a preset condition;
and when the absolute value of the amplitude of the alternating-current voltage waveform is larger than the protection threshold value and the duration is larger than or equal to the set maintaining time, judging that the box transformer does not meet the preset condition.
7. The box-type power supply control system according to claim 5, wherein in the shutdown module, when the control terminal receives the power-off signal, before performing shutdown processing on the UPS power source based on the power-off signal, further comprising:
the closing module receives a verification request sent by the control end, wherein the verification request is sent when the control end receives the power-off signal;
the closing module performs identity verification on the current user based on the verification request, and obtains a login request in a preset area of the control end login interface under the condition that the identity verification is passed, wherein the login request comprises a user account number and a user password;
and the closing module carries out login verification on the current user based on the user account number and the user password, displays an operation selection interface and displays closing operation authority of the UPS on the operation selection interface under the condition that the login verification is passed.
8. The box power supply control system according to claim 5, wherein in the shutdown module, when the control terminal receives the UPS power-off signal, when the UPS power source is turned off based on the UPS power-off signal, comprising:
the closing module is used for setting a power supply branch circuit on the UPS, wherein the power supply branch circuit comprises a switch unit and a power supply unit;
and the closing module sends a closing signal to the switch unit when receiving the UPS power-off signal, and cuts off the power supply unit according to the switch unit.
9. A computer device comprising a processor, a memory, and a tank power control program stored on the memory and executable by the processor, wherein the tank power control program when executed by the processor implements the steps of a tank power control method according to any one of claims 1 to 4.
10. A computer-readable storage medium, on which a box-type power supply control program is stored, wherein the box-type power supply control program, when executed by a processor, implements the steps of a box-type power supply control method according to any one of claims 1 to 4.
