Embodiment Construction

[0037] The present invention is further illustrated below by means of examples, but the present invention is not limited thereto within the scope of the examples.

[0038] figure 1 It is a schematic circuit diagram of a power management device of a numerical control device shown in an exemplary embodiment of the present invention, and the power management device includes: a power transmission circuit 11 , a capacitor module 12 and a backup circuit 13 . The power transmission circuit 11 includes: an input terminal 111 , a first output terminal 112 , a second output terminal 113 , a first diode D1 and a current limiter 114 .

[0039] Wherein, the capacitor module 12 can be formed by connecting many single super capacitors in series and in parallel. The capacitor module 12 includes a voltage equalizing module to prevent voltage imbalance and protect the circuit. In this embodiment, a supercapacitor is used. The supercapacitor has high energy density, short charging time, and un...

Abstract

The invention discloses a power management device and method for numerical control equipment. The power supply management device comprises a power supply transmission circuit, a capacitor module and a backup circuit; under the condition that the output voltage of the external power supply is not smaller than a voltage threshold value, the power supply transmission circuit transmits the power supply of the external power supply to the numerical control equipment and the capacitor module respectively so as to supply power to the numerical control equipment and charge the capacitor module; under the condition that the output voltage of the external power supply is smaller than a voltage threshold value, the capacitor module supplies power to the numerical control equipment, and the backup circuit sends a backup signal to the numerical control equipment so as to write data running in a memory of the numerical control equipment into a hard disk of the numerical control equipment. Therefore, when the numerical control equipment is accidentally or suddenly powered off, the equipment is protected, and the running data is ensured not to be lost.

Description

technical field [0001] The invention relates to the field of data system control, in particular to a power management device and method for numerical control equipment. Background technique [0002] At present, when the numerical control system is running, there will be a large amount of data running in the memory, and there are many variables that are updated in real time. Before the numerical control system is shut down, these data need to be written to the hard disk to ensure that the data will not be lost, or the next time it is turned on It is possible to continue processing from the state at the last shutdown. Once the power is suddenly cut off, the memory data of the data system will be lost, which will have serious consequences, such as damage to the processed workpiece, damage to the processing file, damage to the system file, and more seriously, the system cannot be opened. Therefore, it is very important to ensure that the data or variables operated by the CNC sy...
