A fingerprint module data acquisition device

Abstract

The present invention relates to a fingerprint module data acquisition device, comprising a module interface, a program-controlled power supply module, a current acquisition module, an open-short circuit detection module, a processor, a PHY chip, a communication interface and a system power supply. The program-controlled power module, the current acquisition module, the open-short circuit detection module and the processor are connected; the PHY chip is respectively connected to the program-controlled power supply module, the current acquisition module, the open-short circuit detection module and the The processor is connected; the communication interface is connected with the PHY chip; the system power supply is used to supply power to each module. After the fingerprint module data collection device of the present invention is connected to a PC and uses upper-layer software, it can perform open / short circuit detection, working / standby current detection, and fingerprint module image data collection for the fingerprint module. The device of the present invention facilitates fingerprint module The manufacturer's detection of the fingerprint module.

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...
