Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
In consideration of the fact that in the prior art, when an application scene is changed into a larger electronic device, such as a PC, a tablet computer (including a two-in-one PC) and the like, and a single SAR Sensor is used for trigger detection, the detection is inaccurate and false triggering occurs.
For convenience of understanding, first, a detailed description is given to a method for detecting an electromagnetic wave absorption ratio according to an embodiment of the present invention, referring to a schematic flow chart of the method for detecting an electromagnetic wave absorption ratio shown in fig. 1, the method mainly includes the following steps S102 to S106:
step S102: a sensor instance is created.
In one embodiment, sensor instances (sensor instances) may also be referred to as sensor instances, the sensor instances are representatives of electromagnetic wave absorption ratio sensors (also referred to as SAR sensors) and are used for indicating the electromagnetic wave absorption ratio sensors to be detected, and each sensor instance is created to carry address information of the corresponding electromagnetic wave absorption ratio sensor. The number of the electromagnetic wave absorption ratio sensors is at least two, the number of the sensor examples is arranged corresponding to the number of the electromagnetic wave absorption ratio sensors, namely, each electromagnetic wave absorption ratio sensor corresponds to one sensor example. The creation of the sensor instance may be the creation of a request, and the electronic device (a terminal including a PC, a notebook, etc.) creates the sensor instance by sending a creation request, and the created sensor instance is equivalent to representing the SARsensor on the upper layer of the system. Step S104: when receiving the detection command, the control sensor instance calls the sensor driver.
In an embodiment, when the electronic device is a notebook platform, the detection command is a detection command sent by an upper layer (such as a windows upper layer) of the system to the platform end, the detection command carries an identifier of a corresponding sensor instance, the number of sensor drivers (i.e., sensor drivers) is one, and the sensor drivers called by each sensor instance are all the same sensor driver, i.e., a plurality of sensor instances share one sensor driver. When the electronic device such as the notebook platform receives the detection instruction from the upper layer of the system, since the detection instruction carries the identifier of the sensor instance, the corresponding sensor instance is controlled to call the sensor driver.
Step S106: and detecting the capacitance values of the electromagnetic wave absorption ratio sensor to be detected and the trigger antenna according to the address information by the sensor drive.
In one embodiment, after the sensor instance calls the sensor driver, the electronic device, such as a PC or a notebook computer, queries the corresponding electromagnetic wave absorption ratio sensor chip (also referred to as a sensor IC) according to the address information of the SAR sensor carried in the sensor instance through the sensor driver. The trigger antenna may include an antenna such as a WiFi terminal antenna or a Modem (i.e. Modem) terminal antenna, and the trigger antenna is connected to the sensing antenna chip pin of the electromagnetic wave absorption ratio sensor to be detected. For example, when it is required to detect whether the SAR of the WiFi terminal exceeds the limit, the sensor instance includes the address information of the WiFi terminal, and the found corresponding sensor IC is also the sensor chip connected to the WiFi terminal, and further determines whether the SAR exceeds the limit according to the detected capacitance value between the sensor IC and the antenna.
The method for detecting the electromagnetic wave absorption ratio provided by the invention creates sensor examples, wherein the sensor examples carry address information of corresponding electromagnetic wave absorption ratio sensors, the number of the electromagnetic wave absorption ratio sensors is at least two, and the number of the sensor examples is corresponding to the number of the electromagnetic wave absorption ratio sensors. When a detection command is received, the sensor instances are controlled to call the sensor drivers, the number of the sensor drivers is one, the sensor drivers called by each sensor instance are the same sensor driver, the capacitance values of the electromagnetic wave absorption ratio sensor to be detected and the capacitance value of the trigger antenna are detected through the sensor drivers according to address information, and the trigger antenna is connected with an induction antenna chip pin of the electromagnetic wave absorption ratio sensor to be detected. Through two at least electromagnetic wave absorption ratio sensors, can reduce single sensor because the parasitic capacitance that the line produced is walked to the hardware on the mainboard, set up two at least sensors simultaneously and can make coverage bigger to it is higher to make the SAR of the handheld electronic device of great area trigger the detection accuracy rate. Because at least two sensor instances corresponding to the electromagnetic wave absorption ratio sensor share one sensor drive, more port control can be provided in the antenna design, the platform overhead and the code overhead are reduced, and the overall stability of the platform is improved. Therefore, the embodiment of the invention improves the detection accuracy of the electromagnetic wave absorption ratio, reduces the overhead and improves the overall stability.
In one embodiment, whether the electromagnetic wave absorption ratio of the electromagnetic wave absorption ratio sensor exceeds a preset threshold is determined according to capacitance values of the electromagnetic wave absorption ratio sensor to be detected and the trigger antenna, and the preset threshold is usually set in the sensor drive, so that when the electromagnetic wave absorption ratio exceeds the preset threshold, information is fed back to the radio frequency adjustment module, the frequency of the transmitting end of the trigger antenna is reduced, and electromagnetic radiation to a human body due to the fact that the electromagnetic wave absorption ratio is high is reduced.
After more and more antennas appear, because the port of single SAR Sensor is limited and can not provide more port control, and the design of many sensors can solve such problem, to the condition that 5G scene antennas increase, through designing a plurality of SARSensors, can make every SARSensor independently go to control the detection, the control of a radio frequency end of management and control, its sensitivity is higher, and the effect is better. For creating the sensor instance, the number of the SAR sensors can be determined based on the number of the antennas arranged in the electronic equipment and the number of the induction antenna chip feet of the SAR sensors, and the sensor instance with the corresponding number is created, for example, if the number of the antennas is increased, the number of the increased SAR sensors corresponding to the induction chip antenna feet on the SAR sensors can be determined, and then the sensor instances with the corresponding number are designed to be controlled and processed.
For convenience of understanding, taking two SAR sensors as an example, the invention further provides a method for detecting the electromagnetic wave absorption ratio, referring to a flow chart of another method for detecting the electromagnetic wave absorption ratio shown in fig. 2, preferably, in the design of the main board, two SAR sensors can be respectively placed at the left side and the right side of the main board end according to the unique shape of the notebook.
The method comprises the steps that two independent Sensor instances, namely a Sensor instance 0 and a Sensor instance 1, are created through a Sensor-Platform (Sensor framework Platform), and when a calling instruction from the upper layer of a system is received by the two Sensor instances, the same Sensor drive is called correspondingly, namely the two Sensor instances share the same Sensor drive to operate and process the corresponding Sensor IC. Specifically, after the sensor instance 0 calls the sensor driver, the sensor driver operates and processes the sensor IC 0 according to the address information of the SAR sensor carried in the sensor instance 0, and after the sensor instance 1 calls the sensor driver, the sensor driver operates and processes the sensor IC 1 according to the address information of the SAR sensor carried in the sensor instance 1. Through putting two SAR sensors respectively in mainboard end left and right sides, can reduce the production and the influence of interference capacitance value on the hardware wiring, two same SAR sensors compare in that the scope that a SAR Sensor covered is bigger (the scope that can contact and detect is bigger), and every SARSensor independently goes to manage and control the detection, the control of a radio frequency end, and its sensitivity is higher, and the effect is better. Meanwhile, the method can independently control the two SAR sensors, and the information and data of the two SAR sensors are independently transmitted and reported, so that the influence of data crosstalk of the two Sensor ICs is avoided.
