Embodiment Construction

[0031] The present invention will be further described below through specific embodiments.

[0032] refer to Figure 1 to Figure 3 , a power supply automatic repair system, connected between a switching power supply group and a load group, including a voltage sampling circuit, a current sampling circuit, a filter network, an amplifying circuit, a main control unit, a relay group and a local power supply circuit. The switching power supply group includes n switching power supplies and one standby switching power supply, and the load group includes n loadings, n=1, 2, 3....

[0033] The voltage sampling circuit is connected with the load group and the main control unit to obtain multiple sampling voltages and then send them to the main control unit. The voltage sampling circuit uses n resistance dividers corresponding to the load group, and the nth resistance divider includes two resistors connected in series: the first divider resistor R n1 and the second divider resistor R ...

Abstract

The invention provides an automatic repair system for power supplies. The automatic repair system is connected between a switching power supply set and a load set. The automatic repair system comprises a voltage sampling circuit, a current sampling circuit, a filtering network, an amplifying circuit, a main control unit, a relay set and a local power supply circuit. The main control unit is connected with a relay drive circuit to compare obtained multi-circuit voltage sampling values and multi-circuit current sampling values with preset threshold values respectively to judge whether the sampling values are abnormal, if the voltage sampling values are abnormal, the switching power supply set is abnormal, and the relay drive circuit is controlled to cut off the switching power supply breaking down, and connect the standby switching power supply; if the current sampling values are abnormal, the load set is abnormal, and the relay drive circuit is controlled to cut off the load power supply breaking down; if the voltage sampling values and the current sampling values are abnormal, the switching power supply breaking down and the load power supply breaking down are cut off, and fault phenomena and processing results are reported to a remote terminal. The automatic repair system is multifunctional and can be applied to automatic repair of the direct-current power supplies.

Description

technical field [0001] The invention relates to the field of power supply application management, in particular to a power supply automatic repair system. Background technique [0002] A power supply is an indispensable energy supply device for electronic equipment. In the electronic equipment powered by mains, the current development trend is the switching power supply. Compared with the entire electronic equipment, the general defect of the switching power supply is that it has low reliability and is prone to failure or damage. And once there is a failure or damage, the equipment will be paralyzed. Therefore, switching power supplies often determine the reliability and life of the entire electronic device. Once the switching power supply fails, not only the maintenance cost is high, but also the maintenance period is long. Especially for remote equipment, it will take a long time to stop before repairing, which will affect the normal use of the equipment. Contents of t...
