Abstract

The invention discloses a power-down protection circuit and a robot control system. The voltage of a direct-current power supply end is divided through a voltage dividing unit, and then the divided voltage is outputted. A switch control unit is used for receiving the divided voltage and outputting different detection signals according to the magnitude relation between the divided voltage and a threshold voltage, and a direct current-direct current conversion unit converts the voltage of the direct current power supply end and then outputs a working voltage. When a DC-DC conversion unit outputsa working voltage, a power-down power supply unit charges according to the working voltage and discharges when the DC-DC conversion unit does not output the working voltage, so that power is suppliedto a control processing unit. Different detection signals are received through the control processing unit, and whether the alternating current power supply end is powered down or not is determined according to the different detection signals, so that when it is determined that the alternating current power supply end is powered down, power is supplied in time through the power-down power supplyunit, data can be backed up in time, and the reliability of the system is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a power failure protection circuit and a robot control system. Background technique [0002] At present, the robot control system usually adopts AC voltage power supply for power supply. However, in the case of a sudden power failure of the AC power supply, the robot control system has no time to respond, resulting in data loss or service interruption, which will not only affect the reliability of the robot control system, but even cause permanent damage to the components of the robot control system. sex damage. Therefore, more and more robot control systems require a power-down protection circuit capable of timely determining whether the AC voltage power supply is powered off, so that the robot control system can respond accordingly to the power-off. Therefore, how to set the power-down protection circuit is an urgent problem to be solved. Contents of the invention [0...
