| description | 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 |
