Several inspectors can be used in a set of system software, each inspector can inspect several inspection points, one inspector can be shared by many people, and each inspector can download the fingerprint file data of multiple people, and each inspector can take 1~2 fingerprint coding data. The inspector itself has the functions of a card reader and a fingerprint code collector. When entering the electronic label number and the fingerprint code of the inspector into the system software, there is no need to design a card reader or fingerprint collector for the computer, and the use of the peripheral equipment of the system is minimized.

[0074] The electronic tag in Figure 1 contains electronic coding information, and the coding of each electronic tag is globally unique and cannot be copied or changed. Place electronic labels with different codes on the equipment or lines to be inspected without wiring. Electronic tags do not require power supply, so that specific inspection locations can be identified, that is, electronic label codes correspond to inspection locations one-to-one.

[0075] Electronic tags can be read by contact (TM card) or by induction (radio frequency).

[0076] Figure 3 is a schematic block diagram of the fingerprint inspection device of the present invention, which consists of three major components: a fingerprint module, a main control board, a battery and a power supply circuit, wherein the battery and the power supply circuit are responsible for power supply and battery charging management for each component of the inspection device. Start the inspector through the button on the main control board, and the fingerprint module starts to work. After the fingerprint image information is collected through the finger-taking port, the fingerprint module analyzes it, converts the image into fingerprint code, and compares it with the fingerprint code file in the memory. The result is transmitted to the main control microprocessor (CPU) on the main control board through the communication interface on the fingerprint module. If the comparison fails, the display and the prompt circuit will give an error message. If the fingerprint meets the system requirements, the display and The prompt circuit prompts the operation of reading the electronic label, the CPU drives the electronic label reading circuit to work, reads the code information of the electronic label, and gives a prompt through the prompt circuit after reading the code of the electronic label, and can display the code information of the electronic label on the display, or can The location name and other data information of the electronic label are displayed through the file of the location name corresponding to the electronic label in advance. If the code of the electronic label is read within the specified time or the card reading operation is canceled through the keyboard, the reading will be given through the prompt circuit and the display. Card failure prompt. After successfully collecting the fingerprint code and the electronic label code information, the CPU combines the time in the current clock circuit with the electronic label code and the fingerprint code into an inspection record, which is recorded in the memory. The inspector can also query the inspection records stored in the memory through key operation and display. The inspector is powered by a rechargeable battery, so the inspector needs to use an external charger to charge the battery in the inspector.
