Data acquisition apparatus of fingerprint module group

Abstract

The invention relates to a data acquisition apparatus of a fingerprint module group. The data acquisition apparatus comprises a module group interface, a program-controlled power supply module, a current acquisition module, an open-circuit short-circuit detection module, a processor, a PHY chip, a communication interface and a system power supply. The module group interface is respectively connected with the program-controlled power supply module, the current acquisition module, the open-circuit short-circuit detection module and the processor; the PHY chip is respectively connected with the program-controlled power supply module, the current acquisition module, the open-circuit short-circuit detection module, and the processor; the communication interface is connected with the PHY chip; and the system power supply is used for providing power for all modules. After the data acquisition apparatus is connected with a PC and upper-layer software is used, open-circuit and short-circuit detection, working / standby current detection, and fingerprint module group image data acquisition are carried out on the fingerprint module group. Therefore, the fingerprint module group manufacture can detect a fingerprint module group conveniently.

Description

technical field [0001] The invention relates to the technical field of fingerprint module detection, in particular to a fingerprint module data acquisition device. Background technique [0002] In recent years, smart products have developed rapidly. Fingerprint recognition technology for identity verification has been widely used. Fingerprint modules integrating this technology have also become necessary devices for various mobile terminals and payment terminals. The demand for fingerprint modules is also increasing. A substantial increase. [0003] As the market has higher and higher requirements for the performance and quality of fingerprint modules, manufacturers have become more and more strict about the production and testing of fingerprint modules. Because the test devices provided by the fingerprint module wafer manufacturers have single functions, poor compatibility, and low current The detection accuracy is low, which can no longer meet the production and testing r...
