The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is a kind of schematic diagram of the electronic card of Dynamically Announce of the utility model.

Fig. 2 is a kind of work flow diagram one of the electronic card of Dynamically Announce of the utility model.

Fig. 3 is a kind of work flow diagram two of the electronic card of Dynamically Announce of the utility model.

Specific embodiment

Refering to Figure 1, a kind of electronic card of Dynamically Announce, including MCU, key, the first power management module, RTC time chip, Bluetooth antenna, second source management module and electronic display, the MUC be separately connected the key, First power management module, RTC time chip, Bluetooth antenna, second source management module and electronic display；The key It is connected to the first power management module, first power management module is connected to RTC time chip, the second source management Module is connected to the electronic display, an attendance card built in the electronic display.The attendance card is to support 13.56MHZ ISO14443A attendance card.The RTC time chip is connected to MCU by I2C interface.The model of the MUC nrf52832.The RTC time chip model is PCF8563；First power management module and second source manage mould Block is that mos pipe connects two resistance, is connected to the output interface of MCU later, carries out power supply opening and closes control；Power supply is connected to MCU is powered.

A kind of specific embodiment of the utility model:

As shown in Figures 1 to 3, a kind of electronic card of Dynamically Announce, system time RTC system, input key system, first Power management module, second source management module, electronic display, Bluetooth antenna.The ble association that ble system is carried using chip Stack is discussed, is communicated with bluetooth equipment.RTC is attached communication by I2C interface and MCU, and key system is basic by MCU's Input interface is connect with microcontroller, and the first power management module is responsible for the power supply of entire electronic card.Electronic display module is logical Universal serial bus SPI interface is crossed to be connected with bluetooth MCU.The basic output interface of bluetooth MCU is connected with second source management module, the Two power management modules are connected with the power interface of electronic display.A kind of electronic card of Dynamically Announce is pressed by judgement The time of key input system, by key pressing in 1-3 seconds, into consumption display pattern.Key carries out double hit and is operated into attendance Display pattern consecutively presses key twice in 3 seconds, and for the second time by the key pressing time at 1-3 seconds, key long-pressing is greater than 3 seconds and enters Data synchronous mode, licensing mode.Consumption mode reads system RTC time, reads the included safety zone bluetooth ble mcu and deposits The key data of storage calls the SDK two dimensional code of authorization to generate interface, generates two consumer codes.

The consumption SDK of authorization can be Alipay, wechat, and there is the producer of payment function in Unionpay, and consumption two dimensional code has centainly Timeliness, number, generally 10 seconds are primary, can be used for campus consumption, convenience store's consumption, and public transport is taken etc., safety zone The data in domain can not be read out by violence mode, ensure that the stability of data, safety, consumption system read two codes Data information and settlement center carry out data check, verify and successfully carry out consumption verification, and verification failure consumption system gives prompt. Checking on Work Attendance Mode reads system RTC time, calls attendance SDK to generate attendance one-dimension code and is shown on electronic card, in Time Attendance Device Upper progress attendance operation, attendance verify successfully, give prompt attendance success.

The built-in attendance card of a support NFC 14443A of electronical display card, is registered in the specified enterprising row of equipment After registration, attendance can also be carried out directly on Time Attendance Device.Data synchronous mode opens bluetooth, carries out bluetooth connection, intelligence After Bluetooth terminal passes through authorization identifying, from electronic card bit end synchrodata to blue-tooth intelligence terminal.Blue-tooth intelligence terminal synchronizes RTC Time synchronizes and consumes key, in attendance key to smart card, in storing data to bluetooth mcu.The success of bluetooth mcu storing data Afterwards, into suspend mode.

It is powered by button cell, due to the low-power consumption of bluetooth BLE, bluetooth only in the state of communication, is just opened blue Tooth, as long as electronic display, which is shown, closes power supply for several seconds, standby only has RTC system time to consume power consumption, RTC system The low-power consumption of system time, guarantees that two button cells can be with continuous work 1 year or more.

Although those familiar with the art answers the foregoing describe specific embodiment of the present utility model Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model Fixed, those skilled in the art modification and variation equivalent made by the spirit according to the utility model all should Cover in the scope of the claimed protection of the utility model.
