In this embodiment, the main control module 10 is an MCU, and fig. 2 is a circuit diagram of the MCU according to this embodiment. The MCU is a Micro Controller Unit (MCU), also called a Single Chip Microcomputer (Single Chip Microcomputer), or a Single Chip Microcomputer (Single Chip Microcomputer), and is a Chip-level computer formed by appropriately reducing the frequency and specification of a Central Processing Unit (CPU), and integrating peripheral interfaces such as a memory, a counter (Timer), a USB, an a/D converter, a UART, a PLC, a DMA, etc., and even an LCD driving circuit on a Single Chip, and performing different combination control for different applications. Specifically, the internal program storage area of the MCU is divided into two blocks, wherein one block is a Bootloader area, the other block is an APP running program area, and the Bootloader area is used for guiding an upgrading program so as to jump to the APP running program area; the system program starts to run from BootLoader every time, and jumps by judging whether a complete new program is written in a program temporary storage area (external FLASH). If the new program exists, writing the new program into the APP operation program area, and then jumping to the APP operation program area; otherwise, the old APP program is directly jumped.
The handheld terminal 20 is an intelligent portable terminal with bluetooth function, internet function, and capability of installing an application program, such as an intelligent terminal like a mobile phone, a tablet computer, or a notebook computer. Taking a mobile phone as an example, when the APP of the mobile phone obtains a firmware upgrade notification issued by the platform, and downloads a new firmware package to the mobile phone through the notification; then the APP is connected with the Bluetooth entrance guard, and an upgrading message is sent, so that the Bluetooth entrance guard equipment enters an upgrading receiving mode, and receives a firmware package (upgrading data) for upgrading.
As shown in fig. 3, the bluetooth module 30 includes a bluetooth chip U1, and a TX pin of the bluetooth chip U1 is connected to an RX pin of the MCU, for transmitting the upgrade data from the handheld terminal 20 to the MCU; the RX pin of the Bluetooth chip U1 is connected with the TX pin of the MCU, and is used for receiving the response frame of the MCU and feeding the response frame back to the handheld terminal 20, so that data interaction between the Bluetooth module 30 and the main control module 10 is realized, data interaction between the Bluetooth terminal and the handheld terminal 20 is realized, and the efficiency of upgrading Bluetooth entrance guard firmware is improved.

As shown in FIG. 4, the memory module 40 includes a Flash chip U3, and the SCK, MISO, MOSI and CS pins of the Flash chip U3 are correspondingly connected with the SCK, MISO, MOSI and CS pins of the MCU.
When the mobile phone is used, a frame of upgrading data packet is sent to the Bluetooth module 30 through the wireless Bluetooth, the Bluetooth module 30 receives the frame of upgrading data and sends the frame of upgrading data to an RX pin of the MCU through a TX pin, after the MCU verifies that the data is correct, the MCU performs data writing operation on the storage module 40, executes a write enable command on the storage module 40, firstly, the MCU pulls down the level of a CS pin of the storage module 40, introduces a write enable command code from a MISO pin, collects the write enable command code at the rising edge of the SCK, then pulls up the CS pin, pulls down the CS pin after completing the write enable, sends the write enable command code to the storage module 40 through the MISO pin, then sends a 24-bit address to the storage module 40, then sends bytes to be written to the storage module 40, and pulls up the CS pin after the data is written, thereby completing the operation of writing the frame of upgrading data. Then the MCU sends a receive response frame to the RX pin of the bluetooth module 30, and the bluetooth module sends a receive response frame to the mobile APP to tell the MCU that it has successfully received and written a frame of upgrade data packet into the memory module 40. After receiving the response, the mobile phone can send the next frame data packet, and repeats the above steps until all data packets are received and written into the storage module 40.
After all the upgrade data packets are received, the MCU needs to read the upgrade data packets in the storage module 40 and write them into the MCU, pull the CS pin low, send the command code to the storage module 40 through the MISO pin, and send the command code to the 24-bit address, where the upgrade data packets are collected by the MCU at the rising edge of the SCK. After the memory module 40 receives the external 24-bit address, the data of the corresponding address is sent out from the MOSI pin at the falling edge of the SCK pin, and before the upper bit, after the address data is read, the address is automatically increased, and then the MOSI pin sends out the data of the next address to form a data stream, that is, as long as the clock is working, the stored data of the memory module 40 can be read out through a read command.
And writing the upgrading data into the MCU to complete MCU program jump.
