The MCU is also called a single chip Microcomputer (MCU) or a single chip Microcomputer (MCU), which properly reduces the frequency and specification of a CPU (Central processing Unit), and integrates peripheral interfaces such as a Memory (Memory), a counter (Timer), a USB (Universal serial bus), a/D conversion, a UART (Universal Asynchronous Receiver/Transmitter), a PLC (Planar Light wave Circuit, Planar optical waveguide), DMA (Direct Memory Access), and the like, even a LCD (Liquid Crystal Display) driving Circuit on a single chip, thereby forming a chip-level computer and performing different combination control for different application occasions.

The electronic equipment can also adopt a matrix keyboard consisting of 12 buttons as an input element, and a user inputs a password to the electronic equipment through the keyboard to finish the interaction between the user and the electronic equipment. In addition, the electronic device may adopt a lithium battery as an element of power.

The STM8 of the electronic equipment is used as an MCU, and a minimum system board circuit can be formed by a crystal oscillator and other components. The E-link screen of the electronic device may be connected to the MCU through a Serial Peripheral Interface (SPI) bus, and Interface corresponding to the hardware SPI of the STM 8. The SPI is a high-speed, full-duplex and synchronous communication bus, and only four wires are occupied on pins of a chip, so that the pins of the chip are saved. The matrix keyboard of the electronic device is docked with the external interrupt interface of the MCU. The power supply of the electronic device is directly connected to VCC (voltage Current connector) and GND (Ground) of the MCU.

in the embodiment of the invention, the MCU of the electronic equipment can run in two modes, one mode is a low power consumption mode, and the other mode is a sleep mode. The MCU of the electronic equipment is set to be operated in a low power consumption mode by default, the electronic equipment can be operated in a sleep mode in a non-working mode, when an external interrupt signal of the MCU is received, the MCU is operated from the sleep mode to the low power consumption mode, and after the MCU is used, the electronic equipment is operated from the low power consumption mode to the sleep mode. For example, a matrix keyboard of the electronic device is connected to a General Purpose Input/Output (GPIO) interface of the external interrupt of the MCU, and when a user presses a key on the electronic device, the electronic device returns to the low power consumption mode from the sleep mode due to reception of the external interrupt signal.

in order to more clearly embody the above technical solution, the graphic identification code is taken as a two-dimensional code, and the above technical solution is explained with reference to fig. 4. As shown in fig. 6, a flowchart of an apparatus control method is provided, where a user is a user of a terminal, the user may scan a two-dimensional code of an electronic apparatus using an APP of the terminal to obtain an encrypted character string, the electronic apparatus requests a server for decryption through the APP, the server may return a password obtained by decryption to the electronic apparatus, the electronic apparatus displays the password, and the user inputs the password into the electronic apparatus and uses the electronic apparatus. After the user finishes using, single consumption can be carried out through the interaction between the terminal and the server. After the electronic equipment is used, the two-dimensional code can be refreshed.

Referring to fig. 7, a flowchart of encrypting and decrypting using the RSA algorithm is provided, as shown in fig. 5, an electronic device may encrypt a password using a public key of the RSA algorithm, and generate a two-dimensional code based on the encrypted password, after a user scans the two-dimensional code using an APP of a terminal, the terminal may request decryption from a server, and the server decrypts the password using a private key of the RSA algorithm, and returns the password to the terminal after obtaining the password of the electronic device, so that the user may operate the electronic device using the password.

in the technical scheme, the off-line electronic equipment has the variable password, and compared with the off-line equipment with the fixed password in the related technology, the problem that a user escapes consumption by recording the fixed equipment password can be avoided, and the off-line electronic equipment has obvious advantages in the aspect of equipment safety. Compared with the online variable password device in the related art, the device generally needs to be configured with the SIM card to communicate with the server, and the cost is high, so that the electronic device in the embodiment of the invention has the advantage of cost in the infrastructure of the device, the cost of the device and the large-scale expansion business, and the operation cost of the whole system can be greatly reduced.

The realization of user consumption needs the user to accomplish consumption through the APP on-line check-up at terminal, compares in relevant technology, and off-line equipment consumes through the consumption card (IC-card, RFID card) of firm private agreement, and this scheme is by a wide margin widened user's scope, has avoided because the problem that opens the card, fills the loaded down with trivial details user's that leads to run off, convenience of customers ' use that can be true.

The electronic equipment has low power consumption during operation, does not need additional power access, realizes the whole low-power consumption dormant operation of the electronic equipment by combining the low-power consumption chip and the E-Link screen, displays the two-dimensional code by the E-Link screen, and only runs in a low-power consumption mode during consumption because the power is not consumed when the electronic equipment is not refreshed, and immediately returns to the dormant mode after consumption is finished. Therefore, the electronic equipment can realize power supply in the process of normal operation for many years only through the self-contained storage battery.
