Description
Technical Field
The invention relates to the field of wearable equipment, in particular to a multifunctional watch.
Background
Along with the update of automobile systems and automobile keys, more and more automobile types are provided with automobile intelligent keys, so that a user can conveniently and efficiently start a vehicle, and the driving and vehicle using experience of the user is improved. For example, a Passive Key Entry (PKE) system is built by a wireless module and a key module in a vehicle system (integrated in a specific device, such as a bracelet, a headset, a watch, a mobile phone shell or a mobile phone). And the key module in the vehicle detection range transmits a corresponding response signal according to the specific message transmitted by the vehicle. And the vehicle controls the opening of the vehicle door after receiving the feedback response signal.
However, the general automobile key structure consists of a key body, a key handle, a remote control key and an internal control device, and has single function and higher cost of independent manufacture; with the development and popularization of intelligent hardware, the traditional automobile key form is gradually difficult to adapt to the demand change of the public. The traditional automobile key is large in size and needs to be carried separately, and the function of the traditional automobile key is only limited to opening the automobile door or starting the automobile. For example, the car owner forgets to carry the car key of the car or the car key is lost, which often causes inconvenience in driving.
Therefore, how to adapt to the portable requirement of the vehicle key is the problem to be solved by the invention.
Disclosure of Invention
The multifunctional watch provided by the invention can effectively improve the portability of the automobile key after integrating the functions of the automobile intelligent key, improve the use experience of an automobile owner and enrich the functions of the traditional automobile key.
In a first aspect, an embodiment of the present invention provides a multifunctional watch, including a key module; the key module comprises a processor, a first antenna module connected with the processor, and a second antenna module connected with the processor; the first antenna module is used for receiving a first radio frequency signal; transmitting a signal identification request to the processor, the signal identification request comprising the first radio frequency signal; the processor is used for judging whether the first radio frequency signal meets the requirement of a preset parameter or not according to the signal identification request; under the condition that the first radio frequency signal is judged to meet the preset parameter requirement, determining a second radio frequency signal corresponding to the first radio frequency signal; transmitting the second radio frequency signal to the second antenna module; the second antenna module is configured to transmit the second radio frequency signal.
In the embodiment of the invention, a key module for receiving and transmitting radio frequency signals is added on the basis of a watch structure; the received radio frequency signal is identified and processed mainly through a processor arranged in the key module; after the processor converts a received first radio frequency signal (i.e., an analog signal) stream into a digital signal, and then determines that the converted first radio frequency signal meets parameter requirements (e.g., the signal is parsed or decrypted by a specific format, and the data format and content of the first radio frequency signal therein are determined), a second radio frequency signal corresponding to the first radio frequency signal is determined and fed back to the second antenna module. The processor may determine a second rf signal corresponding to the first rf signal according to a detailed rf protocol or other communication specifications to open a door of the vehicle or start the vehicle. Compared with the prior art, the watch integrating the automobile key function enriches the functionality of the traditional automobile key carrier; the combination of key module and wrist-watch has richened the function of traditional car key to the portability of car key has been promoted.
In particular, in the mode in which the key module is in full duplex, the transmission and reception of the radio frequency signal can be performed simultaneously. Namely, the key transmits the second radio frequency signal through the antenna while receiving the first radio frequency signal (or message) sent by the automobile, identifying the first radio frequency signal and determining the second radio frequency signal corresponding to the first radio frequency signal. When the key module is in a half-duplex mode, a radio frequency signal sent by an automobile is received in a certain time period, the radio frequency signal (namely, a first radio frequency signal) is identified, a feedback signal (namely, a second radio frequency signal) corresponding to the radio frequency signal is further determined, and after a certain time (obviously larger than the time difference between receiving and sending in a full-duplex mode) is separated from the reception of the radio frequency signal, the second antenna module sends the second radio frequency signal.
Further optionally, the processor decrypts and converts the first radio frequency signal according to a certain decryption rule or manner, so as to obtain an analog signal corresponding to the first radio frequency signal. The processor then determines and identifies the analog signal based on the parameter requirements. The first radio frequency signal may be a data stream organized or encrypted in a particular format.
In one possible implementation, the key module further comprises a power supply module; the power supply module is used for supplying voltage to the key module. For example, the power supply module may maintain the general functions of a watch, such as the timing function; the power supply module can also provide the processor with an operating voltage meeting the voltage requirement of the processor so as to maintain the normal operation of the processor.
In one possible implementation, the key module further comprises an input module connected to the processor; the key module is used for receiving a remote control command, and the remote control command is used for instructing the key module to send a remote control signal corresponding to the remote control command so as to control one or more of door opening, door closing, anti-theft state release and anti-theft state opening of a vehicle corresponding to the key module; the processor is further configured to determine the remote control signal according to the remote control instruction. For example, after the owner leaves the vehicle for a distance, recall that the vehicle has not locked. The vehicle owner can control the vehicle to be locked remotely through the keys on the watch. The input module can be a key or a knob (such as a crown) arranged on the watch; or a microphone and other components with a voice acquisition function. When the input module is a crown, the user can operate the crown in a certain manner or step to realize corresponding locking or unlocking functions and the like. When the input module is a microphone, a user can enable a watch worn on the wrist to be close to the mouth, and corresponding functions are triggered through voice; for example, when the user says "lock", the watch receives the information, performs identification and subsequent data processing, and finally achieves the effect of locking the vehicle in a long distance.
Optionally, the input module is further configured to obtain an opening instruction for the key module or a closing instruction for the key module; the processor is further configured to: and activating the key module according to the opening instruction, or closing the key module according to the closing instruction. For example, in the case that the input module includes an open key (or an activation key) and a close key (or a sleep key), when a user presses the open key (or the activation key), the open key triggers a corresponding open command (or a specific electrical signal), and the processor receives the open command and activates the key module in a sleep or close state according to the open command; after the key module is activated or opened, the signal can be effectively received or transmitted through the built-in antenna. Or, after the user presses the close key (or the sleep key), the close key triggers a corresponding close instruction (or a specific electric signal), and the processor closes the key module in the activated or opened state according to the close instruction after receiving the close instruction; after the key module is closed, the electric quantity of equipment can be saved, and the service life and the energy consumption of the key module are prolonged.
In a possible implementation manner, the processor is further configured to stop processing the first radio frequency signal when it is determined that the first radio frequency signal does not meet the preset parameter requirement. For example, in a case where each parameter of the analog signal corresponding to the first rf signal does not meet the preset parameter requirement, the processor terminates the operation of continuing processing of the signal, for example, does not further confirm the second rf signal corresponding to the first rf signal; no further interaction with other modules within the key module based on the first radio frequency signal, etc.
In one possible implementation, the key module further comprises a communication module connected to the processor; the communication module is used for communicating with the terminal equipment. For example, after a user inputs data such as audio, text, image or video through the input module, the input module transmits the data to the processor for processing and processing into a data packet or a data stream meeting the communication requirement, and the data packet or the data stream is sent out through the communication module. In the embodiment of the present invention, the communication function assumed by the communication module may be similar to that of a general communication terminal or communication device.
In one possible implementation, the key module further includes: a memory coupled to the processor; the memory is used for storing codes required by the key module. For example, when the watch is running, the processor in the key module interacts with the memory to obtain the codes or programs required by each functional module or circuit from the memory, so as to ensure the normal use of each corresponding functional module or circuit.
In one possible implementation, the key module further comprises one or more sensors connected to the processor; the one or more sensors are used for detecting and sending human body parameters to the processor; the human body parameters comprise one or more of step number, heart rate, sleeping time and blood oxygen amount; the processor is further configured to receive and process the body parameters from the one or more sensors; the memory is also used for storing the human body parameters. For example, in the case where the user wears a watch, the watch detects the user's real-time heart rate and presents the heart rate value through an output module.
In one possible implementation, the human parameters may further include blood alcohol concentration; the processor is further configured to: acquiring the blood alcohol concentration by the sensor while receiving the signal recognition request; when the blood alcohol concentration is smaller than a preset threshold value, judging whether the first radio frequency signal meets the preset parameter requirement; and when the blood alcohol concentration is greater than or equal to the preset threshold value, making a driving prohibition prompt or closing the key module. For example, when the watch worn by the owner of the vehicle detects that the blood alcohol concentration of the wearing person exceeds 20mg/100ml or 80mg/100ml, the vehicle door cannot be opened even if the owner of the vehicle wears the watch with the function of the vehicle key to enter the signal receiving and transmitting range of the vehicle.
In one possible implementation, the key module further comprises a biometric information module connected to the processor; the biological information module is used for matching second biological information corresponding to the watch according to the first biological information acquired by the watch; the second biological information comprises one or more of a fingerprint, an iris, and facial features of the target person; the processor is configured to: when the first biological information does not match with the second biological information, a driving prohibition prompt is made, and/or the key module is closed. For example, when the multifunctional watch of the owner is lost and other people wear the watch and enter the signal transceiving range of the vehicle, the door of the vehicle cannot be opened or the power system of the vehicle cannot be unlocked because the biological information of the other people is inconsistent with the standard biological information corresponding to the watch. There is no risk of vehicle theft even if the watch is lost. Under the condition that the biological information module is connected with the processor, the key module normally receives and transmits signals, but the processor judges that the biological information of the current watch holder is not matched with the biological information (namely standard biological information) of the person to which the watch belongs, so that the key module cannot be activated to feed back corresponding radio frequency signals.
In a second aspect, an embodiment of the present invention provides a multifunctional watch, including a key module, and a processor connected to the key module; the key module is used for receiving a first radio frequency signal and sending a signal identification request to the processor, wherein the signal identification request comprises the first radio frequency signal; the processor is used for judging whether the first radio frequency signal meets the preset parameter requirement or not according to the signal identification request; if yes, determining a second radio frequency signal corresponding to the first radio frequency signal; transmitting the second radio frequency signal to the key module; transmitting the second radio frequency signal to the key module; the key module is used for transmitting the second radio frequency signal.
In one possible implementation, the watch further includes an input module connected to the processor; the input module is used for obtaining an opening instruction of the key module or a closing instruction of the key module; the processor is further configured to: and activating the key module according to the opening instruction, or closing the key module according to the closing instruction. For example, in the case that the input module includes an open key (or an activation key) and a close key (or a sleep key), when a user presses the open key (or the activation key), the open key triggers a corresponding open command (or a specific electrical signal), and the processor receives the open command and activates the key module in a sleep or close state according to the open command; after the key module is activated or opened, the signal can be effectively received or transmitted through the built-in antenna. Or, after the user presses the close key (or the sleep key), the close key triggers a corresponding close instruction (or a specific electric signal), and the processor closes the key module in the activated or opened state according to the close instruction after receiving the close instruction; after the key module is closed, the electric quantity of equipment can be saved, and the service life and the energy consumption of the key module are prolonged.
In one possible implementation, the key module further comprises a first antenna module; the key module is also used for receiving a first radio frequency signal through the first antenna module. For example, after the key module starts or finishes dormancy, for the first radio frequency signal received for the first time, the key module receives the first radio frequency signal through the built-in first antenna module so as to perform subsequent signal processing.
In one possible implementation, the key module further includes a second antenna module; the key module is specifically configured to: receiving the first radio frequency signal through a first antenna module; and/or transmitting the second radio frequency signal through a second antenna module. For example, in a full duplex mode of the key module, the transmission and reception of the radio frequency signal may be simultaneous. Namely, the key transmits the second radio frequency signal through the antenna while receiving the first radio frequency signal (or message) sent by the automobile, identifying the first radio frequency signal and determining the second radio frequency signal corresponding to the first radio frequency signal. When the key module is in a half-duplex mode, a radio frequency signal sent by an automobile is received in a certain time period, the radio frequency signal (namely, a first radio frequency signal) is identified, a feedback signal (namely, a second radio frequency signal) corresponding to the radio frequency signal is further determined, and after a certain time (obviously larger than the time difference between receiving and sending in a full-duplex mode) is separated from the reception of the radio frequency signal, the second antenna module sends the second radio frequency signal. Alternatively, the first antenna module and the second antenna module may both be separate devices from the key module, or one of the two may be a separate device; the embodiment of the present invention is not limited thereto.
In a possible implementation manner, the watch further includes a power supply module connected to the processor, and the power supply module is configured to provide a voltage to the processor. For example, the power supply module maintains the general functions of a watch, such as the timing function; the power supply module also provides the processor with an operating voltage meeting the voltage requirement of the processor so as to maintain the normal operation of the processor.
In one possible implementation, the watch further includes a communication module connected to the processor; the communication module is used for communicating with the terminal equipment. For example, after a user inputs data such as audio, text, image or video through the input module, the input module transmits the data to the processor for processing and processing into a data packet or a data stream meeting the communication requirement, and the data packet or the data stream is sent out through the communication module. In the embodiment of the present invention, the communication module performs a communication function similar to that of a general communication terminal or communication device. The watch bearing the communication module can be used for carrying out instant messaging or non-instant messaging on terminal equipment (such as a smart phone, a fixed phone, a smart watch and the like). It will be appreciated that the terminal device may comprise a mobile terminal device.
In one possible implementation, the watch further includes a memory coupled to the processor; the memory is used for storing codes or programs needed by the processor and the key module. For example, when the watch is running, the processor interacts with the memory to retrieve from the memory the codes or programs required by the respective functional modules or circuits to ensure the proper use of the respective corresponding functional modules or circuits.
In one possible implementation, the watch further includes one or more sensors connected to the processor; the one or more sensors are used for detecting and sending human body parameters to the processor; the human body parameters comprise one or more of step number, heart rate, sleeping time and blood oxygen amount; the processor is further configured to receive and process the body parameters from the one or more sensors; the memory is also used for storing the human body parameters. For example, in the case where the user wears a watch, the watch detects the user's real-time heart rate and presents the heart rate value through an output module.
In one possible implementation, the human parameters may further include blood alcohol concentration; the processor is further configured to: acquiring the blood alcohol concentration by the sensor while receiving the signal recognition request; when the blood alcohol concentration is smaller than a preset threshold value, judging whether the first radio frequency signal meets the preset parameter requirement; and when the blood alcohol concentration is greater than or equal to the preset threshold value, making a driving prohibition prompt or closing the key module. For example, when the watch worn by the owner of the vehicle detects that the blood alcohol concentration of the wearing person exceeds 20mg/100ml or 80mg/100ml, the vehicle door cannot be opened even if the owner of the vehicle wears the watch with the function of the vehicle key to enter the signal receiving and transmitting range of the vehicle.
In one possible implementation, the watch further includes a biometric information module connected to the processor; the biological information module is used for matching second biological information (namely standard biological information which can be understood as authenticated biological information of a legal holder of the watch) corresponding to the watch according to the first biological information acquired by the watch; the human body parameters can further comprise second biological information, wherein the second biological information comprises one or more of fingerprints, irises and facial features of the target person; the processor is configured to: when the first biological information does not match with the second biological information, a driving prohibition prompt is made, and/or the key module is closed. For example, when the multifunctional watch of the owner is lost and other people wear the watch and enter the signal transceiving range of the vehicle, the door of the vehicle cannot be opened or the power system of the vehicle cannot be unlocked because the biological information of the other people is inconsistent with the standard biological information corresponding to the watch. There is no risk of vehicle theft even if the watch is lost. Under the condition that the biological information module is connected with the processor, the key module normally receives and transmits signals, but the processor judges that the biological information of the current watch holder is not matched with the biological information (namely standard biological information) of the person to which the watch belongs, so that the key module cannot be activated to feed back corresponding radio frequency signals.
In a possible implementation, the watch further comprises a biometric information module connected to the key module; the biological information module is used for matching second biological information corresponding to the watch according to the first biological information acquired by the watch; the human body parameters can further comprise second biological information, wherein the second biological information comprises one or more of fingerprints, irises and facial features of the target person; the key module is configured to: and entering a dormant state or an off state when the first biological information does not match the second biological information. For example, when the owner of the watch loses the watch and a third person wears the watch and is within the signal transceiving range of the vehicle, the key module first verifies that the currently detected biometric information is compared or matched with the standard biometric information (i.e., the biometric information of the original owner of the vehicle, which may be considered as the standard historical biometric information). Under the condition that the key module and the watch are not matched, after the key module receives message information sent by the automobile, relevant response can not be made to the message information, so that the fact that a third person cannot normally open the automobile under the condition that the watch is lost is guaranteed, and the property safety of the automobile owner is guaranteed.
In a possible implementation manner, the processor is further configured to control the key module to shield the first radio frequency signal when it is determined that the first radio frequency signal does not meet the preset parameter requirement. For example, in a case where the processor determines that the parameter conditions of the first rf signal do not conform to the preset signal parameter requirements, the processor may control the key module to no longer receive the rf signal, or shield the rf signal, or send a certain instruction to the key module, so that the key module does not receive the rf signal.
In a third aspect, the embodiment of the present invention provides a multifunctional wearable device, including the functions of any one of the modules in the foregoing first aspect; the multifunctional wearable device has the function of an automobile intelligent key so as to start a target vehicle or control the target vehicle.

Referring to fig. 3, fig. 3 is a schematic diagram illustrating a keyless system according to an embodiment of the present invention; specifically, the Keyless system includes a Keyless Entry/Entry system (PKE) and a Keyless start system (PKE Go), which is different from a conventional key-operated mode for opening a vehicle door and starting a vehicle, for example, a vehicle owner carries a portable device with a smart key function of an automobile, and can unlock the vehicle door when approaching the vehicle, and start an engine of the vehicle by pressing an in-vehicle button after entering the vehicle. As shown in fig. 3, the system architecture includes a transponder 10 and a base station 20; wherein,
the transponder 10 may be a watch with a car key; the transponder 10 may include a key module 102, and the key module 102 may include a key module microcontroller 1023, a low frequency receive module 1021, and a high frequency transmit module 1022. Alternatively, the low frequency receiving module 1021 and the high frequency transmitting module 1022 may be separate devices independent of the key module 102. The low frequency receiving module 1021 and the high frequency transmitting module 1022 may both include antennas or the antennas are independent from the low frequency receiving module 1021 and the high frequency transmitting module 1022, and the antennas are respectively connected to the low frequency receiving module 1021 and the high frequency transmitting module 1022. For example, as shown in the figure, the antenna 1 is connected to a low frequency receiving module 1021; the antenna 2 is connected to a high frequency transmission module 1022, and so on.
After receiving the first rf signal, the low frequency receiving module 1021 sends the first rf signal to the key module microcontroller 1023.
The key module microcontroller 1023 is used for judging whether the first radio frequency signal can be identified by the key module microcontroller according to a preset identification condition; as shown in fig. 3, the first rf signal is a low frequency message with a frequency of 125 Khz. The second radio frequency signal may be a manchester cipher text encoding. After identifying and resolving the first rf signal, the key module microcontroller 1023 determines the parameter requirements of the second rf signal corresponding to the first rf signal; sending each parameter requirement of the second radio frequency signal to the high frequency transmitting module, and modulating a signal meeting the requirement by the high frequency transmitting module 1022 according to the parameter requirement; based on a certain radio frequency communication protocol, the radio frequency signal is transmitted through an antenna.
The base station 20 may include a low frequency transmit module 201, a base station microcontroller 202, a high frequency receive module 203, and an instruction execution module. In the embodiment of the invention, a vehicle or a vehicle body is taken as an example of the base station. The base station 20 may transmit signals with a certain transmission frequency or continuously with a certain coverage range through the low frequency transmission module. When a device containing a key module, such as transponder 10, is present within the signal coverage area, the device receives and recognizes the first radio frequency signal and transmits a corresponding second radio frequency signal. The high frequency receiving module 203 receives the second rf signal through the antenna 3, and sends the second rf signal to the base station microcontroller 202. After receiving and recognizing the second rf signal, the base station microcontroller 202 sends a corresponding instruction (e.g., a door open instruction) to the instruction execution module 204. The unlocking or opening of the vehicle door is controlled by the instruction execution module 204 through a corresponding control circuit and a mechanical structure.
It should be noted that the principle shown in the embodiment of the present invention is only an exemplary description; the present invention relates to content including but not limited to the description of the above module functions, types, and interaction frequencies.
Referring to fig. 4, fig. 4 is a schematic diagram of a functional architecture of a multifunctional wristwatch with a car key function according to an embodiment of the present invention; as shown in fig. 4, the multifunction wristwatch 10 includes a processor 101, a key module 102, a biological information module 103, an input module 104, a sensor 105, a memory 106, a power supply module 107, and a communication module 108. The key module 102 includes a first antenna module 1021 and a second antenna module 1022. The processor 101 is connected with the key module 102; optional modules include a biometric information module 103, an input module 104, a sensor 105, a memory 106, a power module 107, and a communication module 108. The first antenna module 1021 corresponds to the low frequency receiving module and the antenna 1 in fig. 3; the second antenna module 1022 corresponds to the high frequency transmitting module and the antenna 2 in fig. 3.
Specifically, the key module 102 is configured to receive a first radio frequency signal and send a signal identification request to the processor, where the signal identification request includes the first radio frequency signal; the processor 102 is configured to determine whether the first radio frequency signal meets a preset parameter requirement according to the signal identification request; the preset parameter requirements may include the frequency of the signal and the included coding information. If the first radio frequency signal meets the preset parameter requirement, determining a second radio frequency signal corresponding to the first radio frequency signal; transmitting the second radio frequency signal to the key module 102; the key module may be configured to transmit the second radio frequency signal.
In one possible implementation, the multifunction watch 10 further includes an input module 104 connected to the processor 101; the input module 104 is used for obtaining an opening instruction of the key module 102 or a closing instruction of the key module 102; the processor 101 is further configured to activate the key module 102 according to the unlock command, or deactivate the key module 102 according to the unlock command. For example, in the case that the input module includes an open key (or an activation key) and a close key (or a sleep key), when a user presses the open key (or the activation key), the open key triggers a corresponding open command (or a specific electrical signal), and the processor receives the open command and activates the key module in a sleep or close state according to the open command; after the key module is activated or opened, the signal can be effectively received or transmitted through the built-in antenna. Or, after the user presses the close key (or the sleep key), the close key triggers a corresponding close instruction (or a specific electric signal), and the processor closes the key module in the activated or opened state according to the close instruction after receiving the close instruction; after the key module is closed, the electric quantity of equipment can be saved, and the service life and the energy consumption of the key module are prolonged. Optionally, the input module may specifically include various interfaces, keys, a microphone, a touch screen, and the like. For example, the input module may be a watch dial or a certain key on the watch (the key position may be arranged as desired or in combination with the actual structure). The input module in the embodiment of the present invention may also include an antenna, a module or a unit with a communication function, and the like, which are not mentioned in the embodiment.
Optionally, the key module is in a dormant state under the condition that a target signal (such as an activation signal or a specific message of a target vehicle) is not received, so as to save the electric quantity of the watch; alternatively, the user may activate the key module by inputting a module trigger command; further optionally, the key module enters the sleep or off state again after the key opens the door or in case no signal is received for a period of time.
Optionally, the key module 102 further comprises a first antenna module 1021 and a second antenna module 1022; the key module 102 is specifically configured to receive the first radio frequency signal through the first antenna module 1021; and/or transmit the second radio frequency signal through the second antenna module 1022. For example, in a full duplex mode of the key module, the transmission and reception of the radio frequency signal may be simultaneous. Namely, the key transmits the second radio frequency signal through the antenna while receiving the first radio frequency signal (or message) sent by the automobile, identifying the first radio frequency signal and determining the second radio frequency signal corresponding to the first radio frequency signal. When the key module is in a half-duplex mode, a radio frequency signal sent by an automobile is received in a certain time period, the radio frequency signal (namely, a first radio frequency signal) is identified, a feedback signal (namely, a second radio frequency signal) corresponding to the radio frequency signal is further determined, and after a certain time (obviously larger than the time difference between receiving and sending in a full-duplex mode) is separated from the reception of the radio frequency signal, the second antenna module sends the second radio frequency signal.
In a possible implementation, the multifunctional watch 10 may further include a power supply module 107 connected to the processor 101, where the power supply module 107 is configured to provide a voltage to the processor 101. For example, the power module maintains the general functions of a watch (such as the timing function); the power supply module also provides the processor with an operating voltage meeting the voltage requirement of the processor so as to maintain the normal operation of the processor. The power supply module can be a battery and a corresponding voltage adjusting module; the battery can be a rechargeable battery, and the specific form can be a button battery. The power supply module can provide voltage meeting the working requirement of other devices such as a processor. Optionally, the power supply module may be a charging mode in which a charging wire is connected, or a charging mode in which wireless charging is performed; the embodiment of the present invention is not limited thereto.
In a possible implementation, the multifunction watch 10 also comprises a communication module 108 connected to said processor 101; the communication module 108 is used for communicating with a mobile terminal device. For example, after the user inputs data such as audio, text, image or video through the input module 104, the input module 104 transmits the data to the processor 101 for processing and processing into a data packet or a data stream meeting the communication requirement, and the data packet or the data stream is sent out through the communication module 108. In the embodiment of the present invention, the communication module 108 performs a communication function similar to that of a general communication terminal or communication device. The user can carry out voice call, video call or short message receiving and sending and other functions of some basic mobile communication terminals through the multifunctional watch worn by the user.
In one possible implementation, the multifunction watch 10 further includes a memory 106 coupled to the processor 101; the memory 106 is used for storing codes or programs required by the processor 101 and the key module 102. For example, when the watch 10 is in a normal operation state, the processor 101 interacts with the memory 106 to obtain codes or programs required by each functional module or circuit from the memory 106, so as to guarantee normal use of each corresponding functional module or circuit.
In one possible implementation, the watch 10 further includes one or more sensors 105 connected to the processor 101; the one or more sensors 105 for detecting and transmitting human body parameters to the processor 101; the human body parameters comprise one or more of step number, heart rate, sleeping time and blood oxygen amount; the processor is further configured to receive and process the body parameters from the one or more sensors; the memory is also used for storing the human body parameters. For example, in the case where a user wears a watch, the watch detects the user's real-time heart rate and displays the real-time heart rate value through a screen.
In one possible implementation, the human parameters may further include blood alcohol concentration; the processor is further configured to: acquiring the blood alcohol concentration by the sensor while receiving the signal recognition request; when the blood alcohol concentration is smaller than a preset threshold value, judging whether the first radio frequency signal meets the preset parameter requirement; and when the blood alcohol concentration is greater than or equal to the preset threshold value, making a driving prohibition prompt or closing the key module. For example, when the watch worn by the owner of the vehicle detects that the blood alcohol concentration of the wearer exceeds 20mg/100ml (driving standard for drunk) or 80mg/100ml (driving standard for drunk), even if the owner of the vehicle wears the watch with the function of the automobile key and enters the signal transmitting and receiving range of the vehicle, the vehicle does not open the door of the vehicle.
In one possible implementation, the watch 10 further comprises a biometric information module 103 connected to the processor; the biological information module 103 is configured to match second biological information (collected in real time and needing verification) corresponding to the watch according to first biological information (pre-stored biological information for comparison) collected by the watch; the human body parameters can further comprise second biological information, wherein the second biological information comprises one or more of fingerprints, irises and facial features of the target person; the processor 101 is configured to make a driving prohibition prompt and/or turn off the key module when the first biological information does not match the second biological information. For example, when the multifunctional watch of the owner is lost and other people wear the watch and enter the signal transceiving range of the vehicle, the door of the vehicle cannot be opened or the power system of the vehicle cannot be unlocked because the biological information of the other people is inconsistent with the standard biological information corresponding to the watch. There is no risk of vehicle theft even if the watch is lost. Under the condition that the biological information module is connected with the processor, the key module normally receives and transmits signals, but the processor judges that the biological information of the current watch holder is not matched with the biological information (namely standard biological information) of the person to which the watch belongs, so that the key module cannot be activated to feed back corresponding radio frequency signals.
Alternatively, the standard biological information is biological information for comparison with the detected biological information of the current wearer. The standard biological information can be stored in a memory of the watch or stored in the cloud end in a preset mode, and the standard biological information is acquired from the cloud end to be compared when the comparison is needed.
In a possible implementation, the watch 10 further comprises a biometric information module 103 connected to the key module; referring to fig. 5, fig. 5 is a schematic diagram of a functional architecture of another multifunctional watch according to an embodiment of the present invention; as shown in fig. 5, the difference from the connection relationship between the modules shown in fig. 4 is that the biometric information module 103 is connected to the key module 102. After the current biometric information collected by the biometric information module 103 fails to match with the pre-stored standard biometric information, the biometric information module 103 may control the key module 102 to be turned off or to enter a sleep state, so that the key module does not feed back a corresponding signal to open the vehicle door. Alternatively, the key module 102 may also be provided with a dedicated processing module for performing processes such as identification and modulation on the transmitted and received signals. While processor 101 is primarily responsible for data processing and operation of other functions of the watch.
The biological information module 103 is used for matching second biological information corresponding to the watch according to the first biological information acquired by the watch; the human body parameters can further comprise second biological information, wherein the second biological information comprises one or more of fingerprints, irises and facial features of the target person; the key module 102 is configured to enter a sleep state or an off state when the first biological information does not match the second biological information. For example, when the owner of the watch loses the watch and a third person wears the watch and is within the signal transceiving range of the vehicle, the key module first verifies that the currently detected biometric information is compared or matched with the standard biometric information (i.e., the biometric information of the original owner of the vehicle, which may be considered as the standard historical biometric information). Under the condition that the key module and the watch are not matched, after the key module receives message information sent by the automobile, relevant response can not be made to the message information, so that the fact that a third person cannot normally open the automobile under the condition that the watch is lost is guaranteed, and the property safety of the automobile owner is guaranteed.
In the embodiment of the invention, a key module for receiving and transmitting radio frequency signals is added on the basis of a watch structure, and the radio frequency signals fed back by the key module are identified and processed by a processor; after the processor judges that the first radio frequency signal meets the parameter requirements (such as waveform, frequency, amplitude and the like), a second radio frequency signal corresponding to the first radio frequency signal is determined and fed back to the key module. The processor may determine a second rf signal corresponding to the first rf signal according to a detailed rf protocol or other communication specifications to properly open the door or start the vehicle. Compared with the prior art, the watch integrating the automobile key function enriches the functionality of the traditional automobile key carrier; the combination of the key module and the watch reduces the volume of the traditional automobile key and improves the portability of the automobile key.
In the foregoing embodiment, the key module and the processor are separate devices, and the following is a functional architecture of another multifunctional watch provided in the embodiment of the present invention; wherein, the processor is used as a built-in module of the key module.
Referring to fig. 6, fig. 6 is a schematic diagram of a functional architecture of another multifunctional watch according to an embodiment of the present invention; as shown in fig. 6, the multifunction watch 10 may include a key module 102, a power supply module 107, a memory 106, a sensor 105, an input module 104, a communication module 108, and a biological information module 103. The key module 102 may include a second antenna module 1022, a processor 101, and a first antenna module 1021. Alternatively, the power module 107, the memory 106, the sensor 105, the input module 104, the communication module 108, and the biometric information module 103 may be partially or fully integrated in the key module 102. Unlike the processors in the previous embodiments, the processor shown in fig. 6 is used to process not only the radio frequency signals associated with the car key, but also data and functions associated with the basic functions of the watch.
