The main control board 7 is integrated with a microcontroller MCU, a buzzer, an SRAM memory, a FLASH memory and an SD card, wherein the microcontroller MCU adopts an ARM chip with the model number of STM32F407ZGT 6. The wireless communication part 8 is integrated with a serial port WiFi module with the model number of ESP8266, an NB-IoT module with the model number of BC26 and a Bluetooth wireless module with the model number of NRF 52832. The image processing part 9, the wireless communication part 8, the display screen 2, the key part 3, the buzzer, the SRAM memory, the FLASH memory, the SD card and the lithium battery 5 are electrically connected with the MCU at the same time.
