In addition, generally, since the optimal power supply voltage of the data exchange module 200 and the bluetooth module 300 in the attendance device 10 is 5V, and the optimal power supply voltage of the main control module 100, the clock module 400 and the display module 500 is 3.3V, in order to ensure that the attendance device works in a state with better performance, the working power supply module 610 and the standby power supply module 620 should both include a voltage transformation module and a voltage stabilization module, so as to improve the working performance of each module in the attendance device 10.

As shown in fig. 3, the bluetooth-based attendance device 10 according to another embodiment of the present application is substantially the same as the above-mentioned embodiment, and therefore, the same parts are not repeated herein, except that: the attendance device 10 further comprises a power-down protection module 700 (i.e., Flash storage) for storing data in the attendance device 10 when the attendance device 10 is powered down. The data here may include existing attendance data and attendance programs. In this embodiment, preferably, the power down protection module is a W26Q64 chip. The W26Q64 chip is connected with main control module 100 through the SPI serial port, realizes the effect of not losing existing data when attendance device 10 unexpectedly loses power and resets. The W26Q64 chip is powered by a 3.3V DC voltage stabilizing source, the main control module 100 is connected with the CS chip selection end, selects the chip through high and low levels, and is connected with the main control module 100 through SI, SO and CLK pins to realize data input and output and acquire serial clock information. The WP pin of the W26Q64 chip is a protection pin of the chip for preventing the status register from being written, and the low level is active, since the W26Q64 chip needs to keep the program capable of being written, the high level of 3.3V is directly connected to keep the write-enabled status. The HOLD pin allows the W26Q64 chip to disable the select state if it is active and active low, so to avoid the chip select signal being terminated, a 3.3V high connection is used and not allowed to operate. Through the distribution of the pin functions, the data storage is realized, and the power failure is avoided.

Fig. 4 to 13 are specific circuit connection diagrams of the attendance device 10 according to the present application. In the present application, in order to optimize the performance of the attendance device 10, a key module may be further included, which is used to control the start of the attendance device 10; the indicating lamp module is used for displaying the working state of the attendance checking module 10; and the program downloading interface module is used for downloading the attendance related program.

Next, a specific working process of the attendance device 10 is explained to explain the principles of the present invention in further detail:

before attendance checking, a personnel information table is generated in advance. The personnel information table records the one-to-one correspondence relationship between the personnel to be examined and the MAC addresses of the communication equipment held by the personnel to be examined. The personnel information table is stored in the data exchange module 200.

When checking in, the attendance checking device 10 is powered on first, and the first bluetooth module 310 and the second bluetooth module 320 of the attendance checking device 10 are turned on. The personnel information table in the data exchange module 200 is transmitted to the main control module 100, in this embodiment, the manner of transmitting the personnel information table to the main control module 100 may be transmitted through the second bluetooth module 320, and if the data exchange module 200 is a usb disk storage module based on CH376S, the usb disk may be directly inserted into the data exchange interface of the main control module 100 to perform data transmission. When a person to be checked enters the attendance checking range, the bluetooth of the held communication equipment (such as a mobile phone) is opened, the bluetooth of the communication equipment held by the person to be checked is scanned by using the first bluetooth module 310 of the attendance checking device, the MAC address corresponding to the communication equipment is determined according to the bluetooth signal of the communication equipment, and the MAC address acquired by the first bluetooth module 310 is transmitted to the main control module. The main control module matches the MAC address transmitted by the first bluetooth module 310 with the personnel information table transmitted by the data exchange module 200, and feeds back a matching result (i.e., an attendance result) to the data exchange module 200, so that an attendance person takes the attendance result away for analysis. In addition, the attendance result is also displayed in real time through the display module 500. The display module 500 can also display the information of the attendance device, the number of people, the working state of the attendance device, the electric quantity of the attendance device, the real-time information of the attendance device, and the like in real time. In addition, during attendance, if a power failure state occurs, a power failure protection module 700(Flash storage) in the attendance device starts to work so as to store the existing data and programs, and the effect that the data is not lost when the power failure occurs is achieved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
