Please refer to FIG. 1 , which shows a schematic diagram of a communication system applied to an electric tool provided by an embodiment of the present application. The system 100 includes: an external device 110 , an electric tool 120 , and a first electronic tag 121 is arranged on the electric tool 120 .

Exemplarily, the external device 110 may be configured to control the electric tool 120 , for example, the external device 110 may be configured to control working parameters of the electric tool 120 (eg, rotation speed, working duration, working depth, working position, etc.). The external device 110 can be a mobile terminal, and the mobile terminal can be a mobile phone, a smart wearable device (for example, a smart watch, a smart bracelet, etc.), a tablet computer or a control terminal (the control terminal refers to a user terminal produced by an electric tool manufacturer). The type of the external device 110 is not limited in this embodiment of the present application.

It should be noted that the working parameters of different types of electric tools 120 may be different. The working parameters described above are only exemplary and can be set according to actual application scenarios. The application does not limit the type and number of working parameters.

In the embodiment of the present application, the electric tool 120 includes a housing, a motor, an output shaft and a switch system. The housing is formed with an accommodation chamber for setting the motor, the motor is disposed in the accommodation chamber formed by the housing, the output shaft is configured to rotate to output power, and the switch system is configured to be operated by the user to control the electric tool, for example, the switch system can control the following At least one item: the start of the motor, the direction of the motor, etc. It can be understood that the structure shown in the embodiment of the present application does not constitute a limitation to the electric tool. In other possible implementations, the electric tool may also include more or fewer components than those described above, or combine certain components, or split certain components, or arrange different components, which is not made in this embodiment of the present application. limited. Power tools 120 include, but are not limited to: chain saws, electric drills, circular saws, hammer drills, angle grinders, snowplows, lawn trimmers, reciprocating saws, and the like.

In the embodiment of the present application, the electric tool 120 is provided with a first electronic tag 121 . The first electronic tag 121 includes an NFC (Near Field Communication, near field communication) tag or an RFID (Radio Frequency Identification, radio frequency identification) tag.

In a possible implementation manner, the first electronic label 121 on the electric tool 120 is set on the electric tool 120 before the electric tool 120 leaves the factory. Exemplarily, the first electronic label 121 can be affixed in the electric tool 120, for example, the first electronic label 121 can be affixed on the casing of the electric tool 120 (for example, the handle casing, the battery pack casing, the base casing) Body or other casings, etc.), at this time, the outer area of the housing corresponding to the attachment area of the first electronic tag 121 can be provided with a prompt label, and the prompt label is used to remind that the area is provided with the first electronic tag 121, The user can bring the external device 110 close to this area to realize the connection between the power tool 120 and the external device 110 . Exemplarily, the first electronic label 121 can be attached outside the electric tool 120 , for example, the first electronic label 121 can be attached outside the casing of the electric tool 120 . The embodiment of the present application does not limit the installation position of the first electronic tag 121 on the electric tool 120 , and the first electronic tag 121 may be installed at any position of the electric tool 120 that is convenient for the external device 110 to approach.

In a possible implementation manner, the first electronic label 121 on the electric tool 120 is set on the electric tool 120 after the electric tool 120 leaves the factory. For example, the first electronic label 121 can be pasted on the electric tool 120 by a user or a manufacturer. Optionally, the external device 110 can obtain a tag ID (Identification, identification) of the first electronic tag 121 through the first electronic tag 121, and the tag ID of the first electronic tag 121 is used to uniquely identify the first electronic tag 121. During use, the user can configure the correspondence between the tag ID of the first electronic tag 121 and the connection information of the electric tool 120 , so that the tag ID can correspond to the electric tool 120 .

In a possible implementation manner, the first electronic tag includes an NFC tag, and there is no communication interface between the first electronic tag 121 and the electric tool 120 , in this case, the first electronic tag may be a passive tag.

In a possible implementation manner, the external device 110 includes an NFC module. When the NFC module of the external device 110 is close to the first electronic tag 121 , the external device 110 can obtain the connection information of the electric tool 120 , so as to establish a connection with the electric tool 120 based on the connection information. The NFC module of the external device 110 being close to the first electronic tag 121 means that the distance between the NFC module of the external device 110 and the first electronic tag 121 is smaller than a preset threshold. The preset threshold may be 10 cm, 20 cm or other values. The embodiment of the present application does not limit the value of the preset threshold, which may be set by a technician.

Next, the working principle of the first electronic tag 121 will be described. Generally speaking, electronic tags can be divided into three categories: passive tags, semi-active tags and active tags.

Passive tags: There is no internal power supply in passive tags. When the passive tag is approached by the communication module of the external device, it can receive the electromagnetic wave sent by the communication module. The internal integrated circuit of the passive tag is driven by the received electromagnetic wave signal. When the passive tag receives an electromagnetic wave signal of sufficient strength, it can send the data stored in the passive tag to the communication module.

Semi-active tags: Semi-active tags work in a similar way to passive tags. The difference is that the semi-active tag includes a small battery, and the power of the small battery is enough to drive the internal integrated circuit of the semi-active tag, so that the integrated circuit is in a working state. Due to the aforementioned small battery included in semi-active tags, semi-active tags respond faster than passive tags.

Active tags: Active tags include an internal power supply, which is used to supply the power required by the internal integrated circuits to generate external signals. Generally speaking, active tags allow communication over a longer distance, and active tags have a larger storage space, which can be used to store data transmitted from communication modules of other electronic devices.

Exemplarily, the first electronic tag 121 in the embodiment of the present application may be any one of the above-mentioned passive tags, semi-active tags or active tags. In practical applications, considering that passive tags have the advantages of low price, small size and no power supply, the first electronic tag 121 is generally a passive tag.

The first electronic tag 121 is configured to send connection information of the electric tool 120 to the external device 110 in response to the external device 110 approaching the first electronic tag 121 .

Exemplarily, the first electronic tag 121 can determine whether the external device 110 is close to itself by sensing the electromagnetic wave intensity of the external device 110, for example, when the first electronic tag 121 senses that the electromagnetic wave intensity of the external device 110 is higher than a preset intensity, The first electronic tag 121 determines that the external device 110 is close to itself.

Correspondingly, the external device 110 is set close to the first electronic tag 121 to acquire the connection information of the electric tool 120 .

The external device 110 approaching the first electronic tag 121 means that the distance between the external device 110 and the first electronic tag 121 is smaller than a preset threshold, which can be set by a technician. For example, the preset threshold can be 10 cm or 20 cm, etc., which is not limited in this embodiment of the present application.
