Referring to FIG. 4, it is a flowchart of an anti-counterfeiting verification method for another accessory according to an embodiment of the present invention.

In this embodiment, the device is described as an example of a walkie-talkie. The structure is as shown in FIG. 5. The walkie-talkie includes a host 51 and a battery (accessory) 52. The host 51 may include a main control chip 511 and an RF reader. 512, the two are electrically connected and can realize information interaction, and the battery 52 can include a radio frequency electronic tag 521, the radio frequency electronic tag 521 has a built-in memory, and the anti-counterfeiting verification method for the battery 52 can be To include:

Step 401: The battery is connected to the host, and the RF reader is powered on.

In the initial state, the battery 52 is separated from the main unit 51, the radio frequency electronic tag 521 in the battery 52 has no energy supply, is in a power-off state, does not consume the energy of the battery 52, and other protection functions in the battery 52 normally monitor the battery state. When the battery 52 is not inserted into the host 51, the host 51 is de-energized and no module can operate.

When the battery 52 is connected to the host 51, the battery 52 supplies power to the host 51 through Pack+ and Pack-, the main control chip 511 of the host 51 is powered on, and the RF reader 512 is activated, and other modules are temporarily not activated.

Step 402: The RF reader radiates electromagnetic energy to the radio frequency electronic tag.

After the RF reader 512 is started, the electromagnetic energy is radiated outward through the antenna of the host 51 side, and the RF electronic tag 521 of the battery 52 side receives the electromagnetic wave through the antenna and accumulates the working voltage, and then is powered on and resets, and the RF reader 512 and the RF electronic tag 521 You can establish communication.

There may be a plurality of radio frequency electronic tags 521 located within the electromagnetic radiation range of the radio frequency reader 512, such as the radio frequency electronic tag 531 of the battery 53, and the radio frequency electronic tag 541 of the battery 54 in addition to the radio frequency electronic tag 521. After the RF reader/writer 512 establishes communication with each of the RF electronic tags within its range of radiation, the RF reader/writer 512 sends a request message to each of the RF electronic tags.

Step 404: The radio frequency reader receives the serial number of each radio frequency electronic tag.

After receiving the request message sent by the radio frequency reader, each radio frequency electronic tag sends its own identification information, such as a serial number, to the radio frequency reader 512.

Step 405: The radio frequency reader selects one of the serial numbers of the radio frequency electronic tags as the serial number to be verified, and notifies each radio frequency electronic tag of the selection result.

After receiving the respective serial numbers sent by the radio frequency electronic tags, the radio frequency reader/writer 512 selects one of the serial numbers to be verified, for example, selects the serial number corresponding to the radio frequency electronic tag 521, and then the radio frequency reader 512 will The selected serial number to be verified is sent to each radio frequency electronic tag.

Step 408: The radio frequency reader reads the identification information for identifying the accessory in the memory of the radio frequency electronic tag corresponding to the serial number to be verified.

The RF reader/writer 512 can read the identification information of the accessory 52 in the memory of the RF electronic tag 521 according to the determined memory location, and can further transmit the identification information to the master chip 511 of the host 51.

Step 409: The main control chip performs anti-counterfeiting verification on the accessory according to the identification information obtained by the radio frequency reader.

In this embodiment, the identification information of the battery acquired by the radio frequency reader/writer 512 is an encryption value of a special bit of the memory, and the main control chip 511 receives the encryption value and performs a key operation on the encrypted value, according to the operation result. The pre-stored values in the main control chip 511 are compared, if they match or match, the battery 52 is a standard accessory, not an imitation. Otherwise, the battery 52 is a copy.

If the battery 52 is a standard accessory, the main control chip 511 can maintain the power supply state of the power module, and the host powers up other modules, and the whole machine starts normally. If necessary, the host 51 can also read the battery 52 through the RF reader 512. Information, if not necessary, cut off the power supply to the RF reader 512 to stop its operation, so as to avoid interference for normal work. If the battery 52 is a copy, the main control chip 511 controls the power module to be cut off, and the whole machine is powered down.

After the host 51 performs anti-counterfeiting verification on the battery 52, the radio frequency electronic tag 521 hangs and then continues. The foregoing steps 403 to 409 are repeated to perform anti-counterfeiting verification on other batteries, such as the batteries 53, 54.

Moreover, in this embodiment, when a plurality of radio frequency electronic tags are present in the radiation range of the radio frequency reader, the anti-collision step of steps 403 to 406 is added to establish a one-to-one relationship between the radio frequency reader and the radio frequency electronic tag. The communication realizes the anti-counterfeiting verification of the radio frequency electronic tag.

In another embodiment of the present invention, if the accessory needs to be configured, after the step 407, the main control chip sends configuration information to the radio frequency reader, for example, a factory setting parameter, etc., of course, the configuration information may also be Built into the RF reader, the RF reader then sends the configuration information to the RF electronic tag of the accessory. The RF tag is stored in its built-in memory. If the accessory also includes the RF tag. The chip can also send configuration information to the chip of the accessory by the radio frequency electronic tag, and the chip sets the accessory according to the configuration information.
