Description

Technical Field

The present application relates to the field of antenna technology, and more particularly, to a detection method and an electronic device.

Background

With the continuous development of communication technology, in some electronic devices, a plurality of antennas are generally provided. In general, the electronic device needs to detect the antenna before using the antenna, so as to ensure that a channel between the antenna and the control chip is conducted, and the antenna can work normally.

The electronic device typically sends a detection signal to each antenna through the control chip, and then determines the state of each antenna according to a feedback signal returned by the detection signal. In general, the control chip needs to reserve a detection interface for each antenna, and send detection signals to the corresponding antennas through different detection interfaces, so as to avoid the problem that feedback signals fed back by different antennas based on the detection signals sent by the same detection interface cannot be distinguished, and further, the faulty antennas cannot be distinguished. However, it is increasingly difficult to provide a detection interface for each antenna due to the limited number of interfaces on the control chip.

Based on this, how to reduce the number of interfaces on the control chip occupied by detecting the antenna state in the electronic device is a problem to be solved.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. Wherein, in the description of the embodiments of the present application, unless otherwise indicated, "/" means or, for example, a/B may represent a or B; "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In addition, in the description of the embodiments of the present application, "plurality" means two or more than two.

The terms "first," "second," "third," and the like, are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", or a third "may explicitly or implicitly include one or more such feature.

With the development of communication technology, in some electronic devices, a plurality of antennas are usually disposed. Usually, the electronic device needs to detect the antenna before using the antenna, so as to ensure that the path from the control chip to the antenna is normal, and further the antenna can work normally. In general, the control chip sends a detection signal to each antenna, and then determines whether a path between the control chip and the antenna is normal, that is, whether the state of the antenna is normal, according to a feedback signal returned by the detection signal. In general, the control chip needs to reserve a detection interface for each antenna, and send detection signals to the corresponding antennas through different detection interfaces, so as to avoid the problem that feedback signals fed back by different antennas based on the detection signals sent by the same detection interface cannot be distinguished, and further, the faulty antennas cannot be distinguished. However, it is increasingly difficult to provide a detection interface for each antenna due to the limited number of interfaces on the control chip. Particularly in electronic devices employing folding screens, the cables used to connect the antenna and the control chip also occupy space in the electronic device. The control Chip may refer to a System On Chip (SOC), and the reserved interface may refer to a General-purpose input/output interface (GPIO) on the control Chip.

In the following, a folding mobile phone with two display screens is taken as an example, as shown in fig. 1, two display screens (not shown in the figure) are respectively disposed on two PCBs, and the two display screens are connected through a rotating shaft. Wherein the two PCBs are PCB 10 and PCB 20, respectively. In one possible case, the folding screen mobile phone is provided with 2 antennas, namely an antenna 1 and an antenna 2. The antenna 1 is arranged on the PCB 10 and the antenna 2 is arranged on the PCB 20. The control chip 3 is arranged on the PCB 10. In order to detect the states of the antennas 1 and 2, two GPIOs are reserved on the control chip 3 for detecting the antennas 1 and 2, respectively. In the trend of more and more antennas on mobile phones, the number of interfaces on the control chip 3 is limited, and GPIO configuration for each antenna cannot be satisfied.

Further, since the antenna generally transmits a radio frequency signal, the signal-to-noise ratio of the signal is high, and therefore, when the antenna is connected to other devices on the electronic apparatus, in order to avoid interference signals introduced by the other devices, the signal needs to be transmitted through a coaxial cable, such as the coaxial cable 4 in fig. 1. It will be appreciated that the coaxial cable 4 generally requires a larger area of space than the traces on the PCB board. With the trend of miniaturization of electronic devices, there are fewer and fewer sections that can be used as layout coaxial cables. In one possible case, since the antenna 2 and the control chip 3 are provided on different PCBs, the coaxial cable 4 needs to traverse the PCBs 10 and 20 when detecting the antenna 2. Typically, the PCB 10 and the PCB 20 are connected by a rotating shaft (not shown in the figure), and when the rotating shaft rotates, the coaxial cable 4 is easily broken, so the coaxial cable 4 cannot span two PCBs, and a flexible circuit board (Flexible Printed Circuit, FPC) 5 is required to replace the coaxial cable to realize bridging between boards of the two PCBs. The area of the FPC is larger than that of the coaxial cable, and thus the space occupied by the electronic device is further increased.

In view of this, the embodiment of the present application provides a detection method, which may be applied to an electronic device, where the electronic device includes at least two antennas, a control chip, a first circuit and a second circuit, the at least two antennas include a first antenna and a second antenna, the control chip includes a first interface, the first interface in the control chip is connected to the first antenna through the first circuit, the first interface in the control chip is connected to the second antenna through the second circuit, the first circuit is used to turn on a signal with a voltage greater than a preset threshold value, and to cut off a signal with a voltage less than or equal to the preset threshold value, and the second circuit is used to delay processing the signal, the method includes: the method comprises the steps of outputting a first detection signal through a first interface of a control chip at a first moment, outputting a second detection signal through the first interface of the control chip at a second moment, determining a second state according to a first feedback signal, and determining a first state according to the second feedback signal, wherein the voltage of the first detection signal is smaller than or equal to a preset threshold value, the voltage of the second detection signal is larger than the preset threshold value, the second moment is the moment after the first moment, the first feedback signal refers to a signal returned after the first detection signal passes through the first channel and the second channel, the second feedback signal refers to a signal returned after the second detection signal passes through the first channel and the second channel, the first channel refers to a channel between the control chip and the first antenna, the second channel refers to a channel between the control chip and the second antenna, the first state is used for indicating whether the first channel is conducted, and the second state is used for indicating whether the second channel is conducted or not.

Fig. 3 is a schematic diagram of an application scenario of the detection method provided by the embodiment of the present application, and as shown in fig. 3, the detection method may be applied to a folding screen mobile phone. As shown in fig. 3, the folding screen mobile phone 100 generally includes a first area 110 and a second area 120, and the first area 110 and the second area 120 are connected by a rotation shaft 130.

It should be understood that the foregoing is illustrative of an application scenario, and is not intended to limit the application scenario of the present application in any way.

The detection method provided by the embodiment of the application can be applied to a mobile phone with one screen.

The detection method provided by the embodiment of the application can be applied to a tablet personal computer.

The following describes the detection method provided in the embodiment of the present application in detail with reference to fig. 4 to 9.

Fig. 4 is a schematic flow chart of a detection method provided by the embodiment of the present application, as shown in fig. 4, the method may be applied to an electronic device, where the electronic device includes at least two antennas, a control chip, a first circuit and a second circuit, the at least two antennas include a first antenna (i.e. antenna 10) and a second antenna (i.e. antenna 20), the control chip includes a first interface, the first interface in the control chip is connected with the first antenna through the first circuit, the first interface in the control chip is connected with the second antenna through the second circuit, the first circuit is used for conducting a signal with a voltage greater than a preset threshold value, and cutting off a signal with a voltage less than or equal to the preset threshold value, and the second circuit is used for performing delay processing on the signal, and the method includes:

S101, outputting a first detection signal through a first interface of the control chip at a first moment.

The voltage of the first detection signal is smaller than or equal to a preset threshold value.

Since the first circuit is used for conducting a signal with a voltage greater than a preset threshold value and the voltage of the first detection signal is less than or equal to the preset threshold value, the first detection signal output by the control chip cannot pass through the first circuit but can pass through the second circuit. And because the control chip is connected with the first antenna through the first circuit, under the condition that the first detection signal cannot pass through the first circuit, the first feedback signal received by the control chip and returned based on the first detection signal cannot indicate the state of a passage between the first antenna and the control chip, but can indicate the state of a passage between the second antenna and the control chip.

S102, outputting a second detection signal through a first interface of the control chip at a second moment.

The voltage of the second detection signal is larger than a preset threshold value.

The first circuit is used for conducting signals with voltage larger than a preset threshold value, and the voltage of the second detection signal is larger than the preset threshold value, so that the second detection signal output by the control chip can pass through the first circuit and can pass through the second circuit. The control chip is connected with the first antenna through the first circuit and connected with the second antenna through the second circuit, wherein the second circuit is used for carrying out delay processing on signals, so that when the second detection signals can pass through the first circuit and the second circuit at the same time, the delay processing of the signals is based on the second circuit, and the feedback signals which are received by the control chip and are based on the delay processing of the second detection signals through the second circuit are different from the feedback signals which are based on the delay processing of the second detection signals through the first circuit, namely, the feedback signals which are based on the delay processing of the second detection signals through the second circuit are feedback signals which can independently indicate the state of a passage between the first antenna and the control chip.

S103, determining a second state according to the first feedback signal, and determining the first state according to the second feedback signal.

The first feedback signal is a signal returned after the first detection signal passes through the first channel and the second channel, the second feedback signal is a signal returned after the second detection signal passes through the first channel and the second channel, the first channel is a channel between the control chip and the first antenna, the second channel is a channel between the control chip and the second antenna, the first state is used for indicating whether the first channel is conducted or not, and the second state is used for indicating whether the second channel is conducted or not.

As is apparent from the above description of S101 and S102, since the first feedback signal returned based on the first detection signal can indicate the state of the path between the second antenna and the control chip, that is, whether the second path is turned on or not can be determined based on the first feedback signal. Because the feedback signal which is subjected to delay processing through the second circuit based on the second detection signal can indicate the state of the passage between the first antenna and the control chip, whether the first channel is conducted or not can be determined according to the second feedback signal. Therefore, the electronic equipment can respectively determine whether the first channel is conducted or not and whether the second channel is conducted or not through the first detection signal and the second detection signal which are output by the first interface at different moments.

The first channel and the second channel are connected with the first interface, that is, the first channel and the second channel are two channels connected in parallel. It should be understood that the length of the coaxial cable used by the parallel channels is far smaller than that of the coaxial cable used by the serial channels, so that the detection method provided by the embodiment of the application can effectively reduce the length of the coaxial cable used, and further reduce the space occupied by the coaxial cable in the electronic equipment.

Fig. 5 is a schematic flow chart of a detection method provided in another embodiment of the present application, the method may be applied to an electronic device as shown in fig. 6, the electronic device includes a first antenna 10, a second antenna 20, a control chip 140, a first circuit 31, a second circuit 41, a first capacitor 51, a second capacitor 61, a first channel 71 and a second channel 81, the control chip 140 includes a first interface 141, the first interface 141 in the control chip 140 is connected to the first antenna 10 through the first circuit 31, the first channel 71 and the first capacitor 51, the first interface 141 in the control chip 140 is connected to the second antenna 20 through the second circuit 41, the second channel 81 and the second capacitor 61, wherein the first channel 71 is connected to the first capacitor 51 through a first node, the second channel 81 is connected to the second capacitor 61 through a second node, the second channel 81 is grounded through a second node, the first circuit 31 is used for conducting a signal with a voltage greater than a preset threshold value, and a cut-off voltage is less than or equal to the preset threshold value, the first channel is used for isolating the signal and detecting the signal by the first capacitor 61 and the second capacitor is used for detecting the signal, the signal is isolated by the first capacitor and the second capacitor is isolated signal detection method is used for detecting the signal, and the signal is isolated by the first capacitor is detected by the first capacitor and the signal is detected by the first capacitor is 51:

S201, outputting a first detection signal through a first interface of the control chip at a first moment.

S202, outputting a second detection signal through a first interface of the control chip at a second moment.

S203, if the voltage of the first feedback signal is 0, the second state indicates that the second channel is turned on.

S204, if the voltage of the first feedback signal is not 0, the second state indicates that the second channel is not conductive.

It should be appreciated that the control chip is connected through a second circuit, a second channel, a second capacitor, and a second antenna, wherein the second channel is connected to the second capacitor through a second node, and the second channel is grounded through the second node. Since the second channel is grounded through the second node, the voltage of the first feedback signal is 0 when the second channel is in the on state, which corresponds to the control chip being grounded through the second channel. In the case where the second channel is not in the on state, the control chip cannot be grounded through the second channel, and therefore, the voltage of the first feedback signal is not 0. Based on this, the control chip can determine whether the second channel is turned on according to the voltage of the first feedback signal. That is, if the voltage of the first feedback signal is 0, the second channel is turned on, and if the voltage of the first feedback signal is not 0, the second channel is turned off.

In addition, the second channel is connected with the second antenna through a second capacitor, and the second capacitor is used for isolating the first detection signal and the second detection signal. It should be appreciated that the first detection signal and the second detection signal are typically direct current signals, while the operating signal transmitted through the second antenna is typically alternating current signals. The characteristic of the second capacitor is utilized to isolate the direct current so that the first detection signal and the second detection signal cannot reach the second antenna, and further the first detection signal and the second detection signal cannot interfere with normal working signals of the second antenna.

In one possible case, the second feedback signal includes a first sub-signal, where the first sub-signal is a feedback signal of the second detection signal at a third time, where the third time is a time after the second time is separated by a first time period, and the first time period is a time period for the first detection signal to return to the control chip through the first channel. That is, the first sub-signal is that the second detection signal passes through the first circuit and the first channel, and returns the feedback signal at the third moment. The second circuit is used for carrying out delay processing on the signals, so that the time of the feedback signals returned by the second detection signals through the second circuit and the second channel is different from the third time, and the third time is later than the third time.

For example, the control chip outputs the second detection signal at 0ms, where the transmission duration of the second detection signal in the first channel and the first capacitor is 1ms, so that the time when the control chip receives the feedback signal (i.e., the first sub-signal) of the second detection signal returned to the control chip through the first channel and the first capacitor is 1ms. Since the second circuit is configured to delay the signal, for example, the second circuit delays the possible signal by 10ms, the time when the second detection signal returns to the control chip through the second channel and the second capacitor is 11ms. That is, the feedback signal returned by the second detection signal through the first channel and the feedback signal returned by the second detection signal through the second channel have different time, and the first sub-signal received at the 1 st ms can independently indicate the on state of the first channel, so that the control chip can determine whether the first channel is on or not according to the first sub-signal.

S205, if the voltage of the first sub-signal is 0, the first state indicates that the first channel is turned on.

S206, if the voltage of the first sub-signal is not 0, the first state indicates that the first channel is not conductive.

It should be appreciated that the control chip is connected through the first circuit, the first channel, the first capacitor and the first antenna, wherein the first channel is connected to the first capacitor through the first node, and the first channel is grounded through the first node. Since the first channel is grounded through the first node, the control chip is grounded through the first channel when the first channel is in the on state, and thus the voltage of the first sub-signal is 0. In the case that the first channel is not in the on state, the control chip cannot be grounded through the first channel, and therefore, the voltage of the first sub-signal is not 0. Based on this, the control chip can determine whether the first channel is turned on according to the voltage of the first sub-signal. That is, if the voltage of the first sub-signal is 0, the first channel is turned on, and if the voltage of the first sub-signal is not 0, the first channel is turned off.

In addition, the first channel is connected with the first antenna through a first capacitor, and the first capacitor is used for isolating the first detection signal and the second detection signal. It should be appreciated that the first and second detection signals are typically direct current signals, while the operating signal transmitted through the first antenna is typically an alternating current signal. The first capacitor is utilized to isolate the direct current characteristic, so that the first detection signal and the second detection signal cannot reach the first antenna, and further the first detection signal and the second detection signal cannot interfere with normal working signals of the first antenna.

In a possible case, the detection method provided by the embodiment of the application can be applied to a folding screen mobile phone as shown in fig. 3. As shown in fig. 3, the folding screen mobile phone 100 includes a first area 110 and a second area 120, and the first area 110 and the second area 120 are connected by a rotation shaft 130. The folding screen mobile phone 100 further comprises an antenna 1, an antenna 2 and a control chip 140, wherein a first interface 141 in the control chip 140 is respectively connected with the antenna 1 and the antenna 2. Wherein the control chip 140 and the antenna 1 are disposed on the first area 110, and the antenna 2 is disposed on the second area 120.

Since the diode may turn on the signal if the voltage is greater than the threshold value, and may turn off the signal if the voltage is less than or equal to the threshold value, the first circuit may be a diode, as shown in fig. 7, in one possible case. It will be appreciated that the circuit formed by the parallel connection of the resistor and the capacitor may delay the signal and thus, as shown in fig. 7, the second circuit may be a circuit formed by a parallel connection of a resistor and a capacitor.

As illustrated in fig. 7, the voltage value of the first detection signal output by the control chip at the first time is 1.2V. The turn-on voltage of the diode is 1.5V, so at the first moment, the first detection signal cannot reach the first antenna through the diode and the first channel, and the first feedback signal returned based on the first detection signal only indicates whether the second channel is turned on.

The voltage value of the second detection signal output by the control chip at the second moment is 1.8V, so that the second detection signal can be conducted to the first channel through the diode, and a feedback signal of the second detection signal returned to the control chip through the first channel and the first capacitor is received. Meanwhile, the second detection signal can also reach the second antenna through a delay circuit formed by connecting the first resistor and the third capacitor in parallel and the second channel, and then a feedback signal is returned to the control chip. In this process, since the resistance of the first resistor is 100deg.KΩ and the capacitance of the third capacitor is 0.1 μF, the delay time period T=RC=10ms of the delay circuit, so that the feedback signal received by the control chip and returned by the delay circuit and the second channel is later than the feedback signal returned by the diode and the first channel, and there is a delay of 10ms, the control chip can determine the first sub-signal according to the time when the two feedback signals are received, that is, the feedback signal returned by the first channel and the first capacitor to the control chip, and then determine whether the first channel is turned on according to the first sub-signal. The channel states indicated by the feedback signals at different times may be as shown in table 1.

TABLE 1

The voltage of the detection signal is 1.2V, which means the first detection signal, and the voltage of the detection signal is 1.8V, which means the second detection signal. The channel corresponding to the on state indicated by the feedback signal at 1ms is the channel corresponding to the feedback signal returned to the control chip through the first channel. For example, the on state indicated by the feedback signal at 1ms of the second detection signal corresponds to the on state of the first channel, and the first detection signal is different at 1ms, so that there is no feedback signal at 1ms, and therefore the on state of the channel cannot be indicated, that is, there is no corresponding channel. The channel corresponding to the on state indicated by the feedback signal when the first detection signal is at 11ms is a second channel, and the channel corresponding to the on state indicated by the feedback signal when the second detection signal is at 11ms is a second channel.

Alternatively, the number of the first antennas may be plural, for example, as shown in fig. 8, the first antennas may be two antennas, that is, the antennas 11 and 12, respectively. The antenna 11, the antenna 12 and the control chip 140 are disposed in a first area 110 of the folding screen mobile phone 100, the antenna 20 is disposed in a second area 120 of the folding screen mobile phone 100, and the first area 110 and the second area 120 are connected through a rotation shaft 130.

The antennas 11 and 12 may be connected through a cascade network 91, and the cascade network 91 may be as shown in fig. 9.

The cascade network 91 includes a capacitor C1, a capacitor C2, a capacitor C3, an inductor L1, and an inductor L2. The first detection signal or the second detection signal is typically a direct current signal. By utilizing the characteristic of capacitive isolation and communication and the characteristic of inductive isolation and communication, the first detection signal or the second detection signal can be transmitted from the antenna 11 to the antenna 12 through the inductor L1 and the inductor L2 and can not reach other areas through the capacitor C1, the capacitor C2 and the capacitor C3, so that the influence of interference signals introduced in other areas in the electronic equipment on the antenna performance is avoided.
