As shown in fig. 1, an embodiment of the present invention provides a terminal device 100, which may include a first antenna 110, a second antenna 120, and a radio frequency chip 130. The radio frequency chip 130 is in communication connection with the first antenna 110 and the second antenna 120, respectively, so as to implement interaction of data or signals. And, the first antenna 110 and the second antenna 120 are connected in communication.
The distance between the first antenna 110 and the second antenna 120 is not limited, and may be set according to actual application requirements, as long as the distance between the first antenna 110 and the second antenna 120 after the setting is a fixed value. After the first antenna 110 and the second antenna 120 are disposed, the signal strength of the signal transmitted between the first antenna 110 and the second antenna 120 is a fixed value because the distance between the first antenna 110 and the second antenna 120 is a fixed value when the first antenna 110 and the second antenna 120 are not in the failure state. That is, it is possible to determine whether there is a fault between the first antenna 110 and the second antenna 120 by detecting whether there is a change in the signal strength of the signal transmitted between the first antenna 110 and the second antenna 120 during use, for example, when there is a change in the signal strength, it may be determined that there is a fault in at least one of the first antenna 110 and the second antenna 120.
In detail, the first antenna 110 is configured to send a detection signal to the second antenna 120, the second antenna 120 is configured to receive the detection signal and send a signal strength of the detection signal to the rf chip 130, and the rf chip 130 is configured to receive the signal strength and compare the signal strength with a first preset value to determine whether a fault exists in the first antenna 110 and the second antenna 120. Wherein the first preset value is generated when there is no fault in the first antenna 110 and the second antenna 120.
Optionally, the types of the first antenna 110 and the second antenna 120 are not limited, and may be set according to practical application requirements, as long as effective communication connection can be performed between the two antennas to transmit signals, for example, when the first antenna 110 is a main antenna, the second antenna 120 may be a diversity antenna, and when the first antenna 110 is a wifi antenna, the second antenna 120 may also be a wifi antenna.
Alternatively, the number of antennas in the terminal device 100 is not limited as long as there are at least two antennas that can communicate with each other. In this embodiment, when it is determined that at least one of the first antenna 110 and the second antenna 120 has a fault, in order to further confirm that the first antenna 110 has a fault or the second antenna 120 has a fault, the terminal device 100 may further include a third antenna 140. Also, the distance between the third antenna 140 and the first antenna 110 is a fixed value.
The first antenna 110 is further configured to transmit a detection signal to the third antenna 140. The third antenna 140 is configured to receive the detection signal and send the signal strength of the detection signal to the rf chip 130. The rf chip 130 is further configured to receive the signal strength and compare the signal strength with a second preset value to determine whether there is a fault in the first antenna 110 and the third antenna 140. And, the second preset value is generated when there is no malfunction in the first antenna 110 and the third antenna 140.
In detail, considering that only one antenna among the first antenna 110, the second antenna 120, and the third antenna 140 generally has a fault, the rf chip 130 is further configured to determine whether the first antenna 110 or the second antenna 120 has a fault according to whether the first antenna 110 and the third antenna 140 have faults. If the first antenna 110 and the third antenna 140 have a fault, it is determined that the first antenna 110 has a fault, and if the first antenna 110 and the third antenna 140 do not have a fault, it is determined that the second antenna 120 has a fault.
Optionally, the type of the third antenna 140 is not limited, and may be set according to practical application requirements, as long as the third antenna can be effectively in communication connection with the first antenna 110 and the rf chip 130. In this embodiment, if the first antenna 110 is a main antenna, the third antenna 140 may also be a diversity antenna, and if the first antenna 110 is a wifi antenna, the third antenna 140 may also be a wifi antenna.
Further, in order to effectively prompt the detection structure for the detection personnel, in this embodiment, with reference to fig. 2, the terminal device 100 may further include a microprocessor 150 and a display screen 160.
The rf chip 130 is further configured to send a determination result to the microprocessor 150 when determining whether the first antenna 110 and the second antenna 120 have a fault. The microprocessor 150 is configured to receive the determination result and control the display screen 160 to display the determination result to prompt the inspector.
Alternatively, the display screen 160 may display a mode of prompting the inspector, for example, when the determination result is that there is no failure in the first antenna 110 and the second antenna 120, the display screen may display an expression with a positive semantic meaning such as "success", "normal", or "pass", and when the determination result is that there is a failure in the first antenna 110 and the second antenna 120, the display screen may display an expression with a negative semantic meaning such as "failure", or "fail".
Optionally, the specific type of the terminal device 100 is not limited, and may be set according to practical application requirements as long as the terminal device has the rf chip 130 and at least two antennas capable of communicating with each other, and for example, the terminal device may include, but is not limited to, an electronic device such as a mobile phone and a tablet computer.
With reference to fig. 3, an embodiment of the present invention further provides an antenna state detection method applicable to the terminal device 100. The antenna state detection method may include step S110, step S120, and step S130.
In step S110, the first antenna 110 sends a detection signal to the second antenna 120.
In this embodiment, when the first antenna 110 and the second antenna 120 need to be detected for faults, step S110 may be performed to drive the first antenna 110 to transmit a detection signal to the second antenna 120.
The method for driving the first antenna 110 to transmit the detection signal is not limited, and for example, the driving device may be arranged to drive the first antenna 110 to transmit the detection signal, or the microprocessor 150 included in the terminal device 100 may be directly used to drive the first antenna to transmit the detection signal. In detail, the microprocessor 150 may generate a driving signal based on a request of a detection person, so that the first antenna 110 can transmit a detection signal to the second antenna 120 based on the driving signal.
Optionally, the specific content of the transmitted detection signal is not limited, and may be set according to the actual application requirement, as long as the second antenna 120 can effectively perform receiving and identifying.
In step S120, the second antenna 120 receives the detection signal and sends the signal strength of the detection signal to the rf chip 130.
In this embodiment, when the second antenna 120 receives the signal sent by the first antenna 110, it may be determined whether the signal belongs to a detection signal, and if it is determined that the signal belongs to the detection signal, the signal strength of the detection signal may be obtained or calculated, and the signal strength is sent to the rf chip 130 in a data form.
The signal strength transmitted by the second antenna 120 to the rf chip 130 may be automatically transmitted according to a set mode, or may be driven by the microprocessor 150.
In step S130, the rf chip 130 receives the signal strength, and compares the signal strength with a first preset value to determine whether the first antenna 110 and the second antenna 120 have a fault.
In this embodiment, the first preset value is generated when there is no fault in the first antenna 110 and the second antenna 120, for example, the first preset value is obtained by detection and stored in the storage unit of the radio frequency chip 130 when the terminal device 100 is shipped from a factory.
When the received signal strength does not match the first preset value, it may be determined that a fault exists between the first antenna 110 and the second antenna 120, and when the received signal strength matches the first preset value, it may be determined that a fault does not exist between the first antenna 110 and the second antenna 120.
Optionally, when determining whether the signal strength matches the first preset value, the specific determination rule is not limited, and may be set according to the actual application requirement, for example, the signal strength may be determined to match when the signal strength is completely the same as the first preset value, otherwise, the signal strength may be determined to not match, or the signal strength may be determined to match when the difference between the signal strength and the first preset value is within a preset range, otherwise, the signal strength may be determined to not match.
Further, considering that the above method can only determine that at least one of the first antenna 110 and the second antenna 120 is in a failure state, in this embodiment, with reference to fig. 4, when step S130 is executed to determine that the first antenna 110 and the second antenna 120 are in a failure state, the antenna state detection method may further include step S140, step S150, and step S160.
In step S140, the first antenna 110 sends a detection signal to the third antenna 140.
In this embodiment, when the step S130 is executed to determine that the first antenna 110 and the second antenna 120 have the fault, the radio frequency chip 130 may send a prompt signal to the microprocessor 150, so that the microprocessor 150 drives the first antenna 110 to send a detection signal to the third antenna 140 based on the prompt signal, or the microprocessor 150 drives the first antenna 110 to send a detection signal to the third antenna 140 based on an operation performed by a detection person when the detection person knows that the first antenna 110 and the second antenna 120 have the fault.
In step S150, the third antenna 140 receives the detection signal and sends the signal strength of the detection signal to the rf chip 130.
In step S160, the rf chip 130 receives the signal strength and compares the signal strength with a second preset value to determine whether the first antenna 110 and the third antenna 140 have a fault.
In this embodiment, the second preset value is generated when there is no fault in the first antenna 110 and the third antenna 140. When determining whether the first antenna 110 and the third antenna 140 have a fault, reference may be made to the explanation of step S130, which is not described herein again.
In step S170, the rf chip 130 determines whether the first antenna 110 or the second antenna 120 has a fault according to whether the first antenna 110 and the third antenna 140 have a fault.
In this embodiment, the step S130 is performed to determine that the first antenna 110 and the second antenna 120 have a fault, and the step S170 is performed to determine that a faulty antenna specifically exists in the first antenna 110 and the second antenna 120, for example, if the first antenna 110 and the third antenna 140 have a fault, it is determined that the first antenna 110 has a fault, and if the first antenna 110 and the third antenna 140 do not have a fault, it is determined that the second antenna 120 has a fault.
That is, if the first preset value does not match the corresponding signal strength and the second preset value does not match the corresponding signal strength, it is determined that the first antenna 110 has a fault. If the first preset value is not matched with the corresponding signal strength and the second preset value is matched with the corresponding signal strength, it is determined that the second antenna 120 has a fault.
With reference to fig. 5, based on the same concept as the antenna state detection method shown in fig. 3, the embodiment of the present invention further provides another antenna state detection method applicable to the terminal device 100 described above. The antenna state detection method may include step S210, step S220, and step S230.
In step S210, the first antenna 110 sends a detection signal to the second antenna 120 and the third antenna 140, respectively.
In this embodiment, the step S210 may refer to the explanation of the step S110 and the step S140, and is not described in detail herein.
The detection signals transmitted by the first antenna 110 to the second antenna 120 and the third antenna 140 may be the same or different. The transmission times may be the same or different. In this embodiment, the setting is not particularly limited, and may be performed according to the actual application requirements.
In step S220, the second antenna 120 receives the detection signal and transmits the signal strength of the detection signal to the rf chip 130, and the second antenna 120 receives the detection signal and transmits the signal strength of the detection signal to the rf chip 130.
In this embodiment, the step S220 may refer to the explanation of the step S120 and the step S150, and is not described in detail here.
In step S230, the rf chip 130 compares the signal strength transmitted by the second antenna 120 with a first preset value and compares the signal strength transmitted by the third antenna 140 with a second preset value, so as to determine whether each antenna has a fault.
In this embodiment, the first preset value is generated when there is no fault in the first antenna 110 and the second antenna 120, and the second preset value is generated when there is no fault in the first antenna 110 and the third antenna 140. Moreover, the rule for determining whether each antenna has a fault may include: if the first preset value is not matched with the corresponding signal strength and the second preset value is not matched with the corresponding signal strength, it is determined that the first antenna 110 has a fault; if the first preset value is not matched with the corresponding signal strength and the second preset value is matched with the corresponding signal strength, it is determined that the second antenna 120 has a fault; if the first preset value matches the corresponding signal strength and the second preset value does not match the corresponding signal strength, it is determined that the third antenna 140 has a fault.
In summary, according to the antenna state detection method and the terminal device 100 provided by the present invention, through the cooperative arrangement between each antenna and the rf chip 130, the characteristics that the distance between each antenna is a fixed value and the strength of the signal transmitted and received between each antenna is also a fixed value based on the fixed value are utilized, and the signal strength detected in real time is compared with the preset value set based on the above characteristics, so as to determine whether the antenna has a fault according to the comparison result, thereby improving the problem of inconvenient detection caused by adopting a special detection device to perform fault detection in the prior art. Further, by performing detection using each device included in the terminal device 100 itself, it is possible to avoid a problem of high detection cost due to failure detection using a special detection device.
