Detailed ways

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

Figure 1 is a device for prompting signal transmission location provided by an embodiment of the present invention, as shown in Figure 1, including:

At least one of the signal receiver or the signal transmitter 101 is used to transmit signals between devices; the signal detection unit is used to detect the signal after receiving the trigger; the analysis unit is used to analyze the signal transmission position based on the detected signal strength; The UI prompting unit is configured to prompt signal transmission position information according to the analysis result of the analysis unit.

Wherein, the signal detection unit 101 may add detection circuits for adjusting and adapting signal powers of different power levels, and expanding the dynamic range of signal powers that can be processed.

Wherein, the signal detection unit is used to detect the signal after receiving the trigger. The amplitude of the magnetic field is changed, and the signal energy is also coupled to the coil. The magnetic induction change signal coupled to the coil is converted into a voltage or current signal through the internal sampling circuit of the signal detection unit, and the signal strength can be detected by periodically recording the voltage or current value in real time according to the time axis.

Wherein, the analysis unit 102 may add an acceleration sensor detection unit for calculating the deviation state and orientation information between the device position and the target signal transmission position. in,

The working principle of this method is that the relative positions of the antennas of the signal transmitting device and the signal receiving device directly affect the signal strength. When the device is used as a signal transmitting device, it sends a magnetic field signal of a certain strength through the antenna coil, and the signal receiving device acts as a load. When the antenna coils of the two devices are close to each other, the amplitude of the transmitted signal will change with the matching of the load. When the two devices When the two coils are aligned, the magnetic induction intensity gradually increases and approaches the maximum value; when the two coils are far away from or, the magnetic induction intensity gradually weakens until it is less than the minimum value. Similarly, when the device is used as a signal receiving device, it receives the field strength signal from the signal transmitting device through the antenna coil, and the antenna coil is used as a load, and the change of the position of the antenna coil of the signal transmitting device causes the load matching degree to change, thereby changing the device coil on the coupled signal.

Therefore, the target signal transmission position can be calculated by comparing the first reference marker parameter converted from the real-time signal with the reference marker parameter. Specifically, there are two different implementations. First, the reference mark parameter can be converted by detecting the signal strength range that can realize signal transmission in advance, and can include a maximum value and a minimum value. That is, when the first reference mark parameter is the same as the preset maximum value of signal strength or the difference is less than a certain range, it can be determined that the device is aligned with the target signal transmission position. Second, the reference mark parameter can also be converted from a signal detected by the signal detection unit within a certain period of time after receiving the trigger, and can include a maximum value and a minimum value. That is, when the maximum value of the first reference marker parameter and the converted reference marker parameter of the detected signal strength are the same or the difference is less than a certain range, it can be determined that the device is aligned with the target signal transmission position.

By adding an acceleration sensor to the analysis unit, when the device receives a trigger, the difference between the first reference mark parameter and the reference mark parameter, the movement amount of the device, and the acceleration value are one-to-one correspondence, and the device can be calculated. Offset and direction information from where the target signal is transmitted.

Finally, the UI prompting unit can prompt the information of the target signal transmission position through the offset and overlap of the two images. Specifically, when the difference between the first reference marker parameter and the maximum value of the reference marker parameter is zero or less than a certain value, the device is prompted to align with the target signal transmission position.

Step S101: After receiving the trigger, detect the signal;

Step S102: Based on the detected signal, analyze the transmission position of the target signal;

Step S103: Prompting signal transmission location information according to the analysis result of the target signal transmission location.

Wherein, after receiving the trigger, detecting the signal includes: adjusting and adapting the power of N signals of different power levels, and expanding the dynamic range of signal power that can be processed.

Wherein, the analyzing the transmission position of the target signal based on the detected signal includes: determining the orientation information for determining the transmission position of the target signal.

Specifically, according to the analysis result of the target signal transmission location, prompting the signal transmission location information includes but is not limited to prompting the user with relevant information by means of images, sounds, vibrations, and the like.

Specifically, according to the analysis result of the target signal transmission position, prompting the signal transmission position information includes: prompting the deviation status and direction between the device to which the method is applied and the target signal transmission position through the change of the deviation or overlap state of the two images information. For example, if the two straight lines or graphics are completely overlapped, it will prompt that the equipment using the method is aligned with the target signal transmission position; if the two straight lines or graphics are separated, it will indicate that the equipment using the method deviates from the target signal transmission position.

FIG. 3 is a schematic diagram of a detection circuit in the signal detection unit in FIG. 2 provided by an embodiment of the present invention. As shown in FIG. 3 , it includes a coupling terminal, a variable gain amplifier, and the like.

Specifically, the amplifier here takes the adjustable gain amplifier VGA as an example, and the purpose of adding the amplifier is to expand the dynamic range of signal power that can be processed. There is no uniform standard for the signal power specifications of the signal transmitting device and the signal receiving device, and the power levels may vary greatly. By adding an amplifier, when the device starts signal detection, the detection circuit adjusts the gain level of the amplifier in a timely manner when the power difference between the signal transmitting device and the signal receiving device is large, so as to ensure that the device can accurately detect the signal strength in a wider range. For the power levels of the general signal transmitting device and the signal receiving device, the amplifier does not need to work. Only when the signal receiving device and the signal transmitting device have a large power difference, the amplifier will be used.

Fig. 4 is a flow chart of a method for prompting a signal transmission location provided by an embodiment of the present invention. As shown in Fig. 4, when a trigger is received, signal detection begins; when the signal transmitting device and the signal receiving device are connected When the difference in signal power is large, adjust and match the signal power of different power levels; then convert the detected signal into the first marking parameter and compare it with the reference marking parameter to determine the transmission position of the target signal; and then prompt the target signal Information about the transfer location. Specifically, if the device is aligned or close to the target signal transmission position, the process ends after relevant information is prompted. If the device deviates from the target signal transmission position, after the relevant information is prompted, if the device moves, the target transmission position is further determined based on the detected signal strength until the device is aligned with the target signal transmission position, and the process ends.

Although the present invention has been described in detail above, the present invention is not limited thereto, and various modifications can be made by those skilled in the art based on the principle of the present invention. Therefore, any modifications made according to the principles of the present invention should be understood as falling within the protection scope of the present invention.
