Abstract

The invention discloses a power supply system for data acquisition equipment, which comprises a mains supply connection port, wherein the mains supply connection port is used for externally connectingthe mains supply and used for supplying power to the data acquisition equipment. The power supply system further comprises a super-capacitor and a super-capacitor control circuit and a super-capacitor protection circuit which are connected with the super-capacitor, wherein the super-capacitor is used for supplying power to the data acquisition equipment, and the data acquisition equipment can also charge the super-capacitor. The power supply system adopts the super-capacitor to supply power to the data acquisition equipment in the case of sudden power outage so as to complete data preservation and prevent data loss. The power supply system is applicable to the field of the data acquisition equipment.

Description

technical field [0001] The present invention relates to the field of data acquisition equipment, and more specifically, to a power supply system for data acquisition equipment. Background technique [0002] With the advancement of science and technology, the development of technology and the increase of business needs, people have higher and higher requirements for information statistics and analysis. The stability and integrity of data collection in the era of big data information is one of the most crucial factors. To ensure the integrity of information collection, it is first necessary to ensure that the data collection equipment can operate normally. The continuous power is the advance to ensure the stable operation of the collection equipment. The power of existing data acquisition equipment generally adopts mains power supply; [0003] There are still deficiencies in this power supply mode: as in the case of a power outage emergency, the data collected by the data ac...
