And guide the operation through text or graphics.
[0072] Compared with the prior art, the present invention has the following advantages: it integrates three main factors (personnel, location, time) in the inspection process to make it consistent, and introduces the fingerprint identity verification technology, which fundamentally eliminates the generation of punch cards occurrence of the phenomenon. In addition, the inspector does not store the fingerprint image, but the fingerprint image collected by the fingerprint acquisition module is directly converted into a specific fingerprint code. The memory of the inspector stores the fingerprint code file of the inspector, and the comparison of the fingerprint code information is performed by the inspector itself. After completion, the identity of the inspector can be verified immediately. Not only the work efficiency is improved, but also the memory utilization efficiency of the inspector is greatly improved. At the same time, the computer management software does not need to compare the fingerprint image information when analyzing the inspection results, which reduces the computational complexity of the computer management software and improves the operating efficiency of the system. The knowledge of image processing, the difficulty of secondary development is also greatly reduced.
[0073] As shown in Fig. 1, the present invention is composed of several parts such as patrol management system software, patrol device and electronic label on the computer. 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. User operations in practical applications are also minimized to the greatest extent, reducing user investment.
[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.
[0077]FIG. 5 is a flow chart of the software work of the inspection system of the present invention. After the system software is logged in by the user authorized by the system and the correct password, the information of inspection locations and inspectors is added to the system through the basic data management module. , the inspection event is a preset event that may occur during the inspection process, such as the window is not closed, the door is not locked, etc., among which the electronic label number and fingerprint code can be input through the inspector without special input equipment. Then, according to the inspection rules or different inspection areas, the location is divided into different inspection lines, and the schedule setting of the inspection personnel, and the inspection time plan is set for the inspection line. Download the fingerprint code file registered by the inspector and the information of the inspection location to the inspector through the communication module of the inspector, and set the corresponding parameters, such as correcting the inspector clock, setting the inspector code, etc. After the inspection, the inspectors will read the records in the inspector into the system database through the communication module, and the data analysis module will analyze and compare the inspection plan with the inspection records, such as the location, time, and personnel set in the pre-software. If the inspection is required, it is qualified, otherwise it is not inspected or missed. The results of the comparison can be queried through the query and statistics module according to conditions such as time, place, personnel, and route. The query results can be output through a printer or exported as report documents in other formats.

In the software database, it is used to identify the inspectors; set up inspection routes, inspection plans and schedules; download the fingerprint code files of the inspectors to the inspector; inspectors carry the inspector to the specified location at the specified time and start the inspection. The inspector, according to the prompt (can be sound, light or text, etc.) to input the fingerprint, after the inspector collects the fingerprint, it immediately compares with the fingerprint file stored in the inspector, if there is such an inspector's fingerprint file, this place The electronic label number, current time, and fingerprint code of the personnel are stored in the memory of the inspector as the inspection record, and the inspector will send out correct prompts (sound, light or vibration, etc.) at the same time to complete the inspection task; if there is no such person's fingerprints The file gives an error message and does not store this inspection record. The supervisors input the inspection records in the inspector into the management software in the computer, and the software analyzes the set routes, plans and shift information, and can query the completion status of the inspection work according to the analysis results.
