【Detailed ways】

In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

Referring to FIG. 1 , FIG. 1 is a schematic flowchart of an embodiment of a radio frame processing method of the present application. Specifically, the radio frame processing method of the present application includes the following steps:

Step S11: Acquire current power supply capability information of the terminal.

The terminal that implements the communication control method of the present application is, for example, a wireless communication device, and the wireless communication device can be an Internet of Things terminal, such as a temperature sensor, a humidity sensor, and an air pressure sensor. The wireless communication device can also be a smart wearable product, such as a smart watch and a smart bracelet. The wireless communication device may also be a wireless walkie-talkie, a mobile phone, and the like.

The current power supply capability information of the terminal may include the current maximum current that the power supply can provide, the current amount of power stored by the power supply, or the charging time of the power supply, etc. It is understandable that the factors related to the output power of the power supply belong to Current power supply capability information.

When the number of power sources is several, the current power supply capability information may be the several current power supply capability information. For example, when the terminal has two power sources, the current power supply capability information may be the current power supply capability information of the two power sources respectively. It can be understood that when the terminal has multiple power sources, one of the power sources can be set as the main power source to supply power when the terminal transmits wireless frames, and the rest of the power sources can be used as backup power sources. When the main power supply is insufficient or out of power, the main power supply is charged by the standby power supply, or the standby power supply and the main power supply are used to supply power when the terminal transmits wireless frames. In a specific implementation scenario, the main power supply is a capacitor, which is used to supply power for the terminal to transmit wireless frames, and the backup power supply is a discharge power supply, which is used to charge the capacitor. In another specific implementation scenario, the main power supply and the backup power supply are both discharge power supplies. When the main power supply is insufficient, the main power supply and the backup power supply together supply power for the terminal to transmit wireless frames.

Step S12: Determine the transmission parameters of the wireless frame of the terminal according to the current power supply capability information, so that when the terminal transmits the wireless frame according to the transmission parameters, the power supply capability of the current power supply can meet the instantaneous energy demand of wireless transmission.

After obtaining the information about the current power supply capability of the terminal, the transmission parameters of the radio frame of the terminal can be determined according to the power supply situation. The transmission parameters of the radio frame include, for example, the frame length and/or the frame interval of the radio frame. The frame length of the radio frame refers to the length of one radio frame, for example, 100 milliseconds and so on. The frame interval is the interval between sending two radio frames. For example, if the first radio frame is sent at the current moment, and the second radio frame is sent 3 seconds later, the frame interval is 3 seconds.

The transmission parameters of the wireless frame of the terminal are determined according to the current power supply capability information. For example, the frame length of the wireless frame that can be sent can be determined according to the current stored power of the power supply, or the wireless frame to be sent can be determined according to the charging time of the power supply. The shortest frame interval of the frame.

By obtaining the current power supply capability information of the terminal, and using this to determine the transmission parameters of the terminal's wireless frame, when the terminal sends the wireless frame according to the transmission parameters, the current power supply capability can meet the instantaneous energy demand of wireless transmission, so that The normal transmission of the wireless frame is realized without additional design of the circuit, the cost of the terminal is reduced, and the competitiveness of the product is improved.

The following is another embodiment of the radio frame processing method of the present application. Specifically, this embodiment includes the following steps S21-S22.

Step S21: Acquire current power supply capability information of the terminal.

Please refer to the above step S11, which will not be repeated here.

In one embodiment, the power source includes an energy storage element, such as a capacitor. The energy storage element can store electrical energy, which is used to provide electrical energy when the terminal sends wireless frames, and provides an instantaneous large current for the terminal to meet the power consumption demand of the terminal, so that the terminal can send wireless frames normally. In some embodiments, the energy storage element may also be an inductor.

The current power supply capability information may include the electricity storage condition and/or the charging duration of the energy storage element, for example, the electricity storage condition and/or the charging duration of the capacitor. The electricity storage condition is the amount of electric energy stored by the energy storage element. The charging time can be understood as the time required for the electric energy stored by the energy storage element to go from 0 to full.

In one embodiment, the power source further includes a discharge power source, such as a low self-discharge battery, specifically a low self-discharge NiMH battery. The discharge power supply can charge the energy storage element, so that the energy storage element can provide the instantaneous high current required by the terminal to transmit the wireless frame. Specifically, the charging duration for charging the energy storage element by the discharging power source can be determined according to the remaining power of the discharging power source. The remaining power of the discharged power supply can be estimated based on information such as battery voltage, ammeter, and equipment operating time. The charging time of the energy storage element is calculated according to the specific type of the energy storage element. For example, when the energy storage element is a capacitor, it can be calculated by the charging calculation method of the capacitor. When the energy storage element is an inductor, the The energy storage formula is calculated.

Step S22: Determine the transmission parameters of the radio frame of the terminal according to the current power supply capability information.

Please refer to the above step S12, which will not be repeated here.

In one embodiment, the frame length of the wireless frame may be determined according to the power storage condition of the energy storage element, that is, the frame length of the wireless frame may be determined according to the amount of electrical energy stored by the energy storage element. Because the energy storage element is used to provide electrical energy for the terminal to send wireless frames, the amount of electrical energy stored by the energy storage element determines the longest time that the terminal can work when transmitting a wireless frame, that is, it determines the amount of electrical energy the terminal can transmit. The frame length of the radio frame. For example, when the stored electric energy of the energy storage element can only keep the terminal in the transmitting state for 400 milliseconds, the frame length of the wireless frame can be determined accordingly to be no greater than 400 milliseconds, for example, 380 milliseconds.

In one embodiment, the electricity storage condition of the energy storage element is determined according to the current ambient temperature of the terminal. The current ambient temperature of the terminal can be obtained through the built-in temperature sensor of the terminal. Because the ability of the energy storage element to store electrical energy is affected by temperature, the electricity storage condition of the energy storage element can be determined according to the current ambient temperature of the terminal. For example, when the energy storage element is a capacitor, the capacitance of the capacitor at a certain temperature can be obtained according to the change curve of the capacitance of the capacitor with the temperature, so that the storage condition of the capacitor can be determined.

In this way, the frame length of the wireless frame is determined according to the power storage condition of the energy storage element, so that when the terminal sends a wireless frame, the wireless frame can be successfully sent, and the sending of the wireless frame will not fail due to lack of power.

Please refer to FIG. 2 . FIG. 2 is a first schematic flowchart of another embodiment of the radio frame processing method of the present application. Specifically, the above-mentioned determination of the frame length of the wireless frame according to the power storage condition of the energy storage element includes the following steps S221 and S222.

Step S221: Obtain the frame length required for the data to be sent, and obtain the maximum frame length that can be sent by using the electrical energy stored in the energy storage element.

When the terminal needs to send data, the data volume of the data to be sent by the terminal can be obtained, and the frame length required for the data to be sent can be determined according to the size of the data volume. For example, when the amount of data to be sent is 58B, the frame length of the radio frame required for sending 58B data can be determined accordingly, for example, 400 milliseconds.

The maximum frame length that can be sent using the electrical energy stored by the energy storage element can be understood as the maximum duration that the electrical energy stored by the current energy storage element can keep the terminal in the transmitting state, which is also the maximum frame length that the terminal can send. For example, if the electric energy stored in the capacitor is 45 mA, and the terminal can maintain the transmitting state for 400 milliseconds, it can be determined that the maximum frame length that can be transmitted by the electric energy stored in the energy storage element is 400 milliseconds.

Step S222: If the frame length required by the data to be sent is greater than the maximum frame length, the data to be sent is divided into at least two radio frames for transmission, wherein the frame lengths of the at least two radio frames are both smaller than the maximum frame length.

When the frame length of the data to be sent is greater than the maximum frame length that can be sent by the energy stored in the energy storage element, it means that the terminal cannot send all the data to be sent by sending one wireless frame. Because the power of the energy storage element is exhausted, the wireless frame transmission will fail, affecting the normal operation of the terminal. Therefore, at this time, the data to be sent can be divided into at least two radio frames for transmission, and the frame length of each frame in the at least two radio frames can be set to be smaller than the maximum frame length that can be sent by the energy stored in the energy storage element, so as to This can enable the terminal to send data normally, so that the terminal can work normally. In a specific implementation scenario, the data to be sent may be divided into two radio frames for transmission, and the frame length of each radio frame is smaller than the maximum frame length.

In some embodiments, the terminal may also divide the data to be sent into three radio frames or four radio frames for transmission.

By dividing the data to be sent into at least two wireless frames (the frame length is less than the maximum frame length) to send the data, the terminal can determine the frame length of the wireless frame according to the energy storage condition of the energy storage element, and finally the terminal can send data normally.

In one embodiment, the frame interval of the radio frame may be determined according to the charging time of the energy storage element. When the electrical energy stored in the energy storage element is consumed, it needs to be fully charged before it can provide electrical energy to the terminal again. Therefore, the frame interval of the wireless frame can be determined according to the charging time of the energy storage element. In one embodiment, the charging time of the energy storage element is 1.5 seconds, and the frame interval of the wireless frame can be set to be no less than 1.5 seconds.

In this way, by determining the frame interval of the wireless frame according to the charging time of the energy storage element, each time the terminal sends a wireless frame, the energy storage element is fully charged, which can provide power for the terminal to send the wireless frame, so that The terminal can send radio frames normally and work normally.

Please refer to FIG. 3 . FIG. 3 is a second schematic flowchart of another embodiment of the radio frame processing method of the present application. Specifically, the above-mentioned determination of the frame interval of the wireless frame according to the charging duration of the energy storage element includes the following steps S223-S225.

Step S223: Determine whether the current frame interval is less than the charging duration.

The terminal can obtain the current frame interval and determine whether the current frame interval is less than the charging time. For example, if the current frame interval is 2 seconds and the charging time is 3 seconds, the frame interval is smaller than the charging time.

If the current frame interval is less than the charging duration, step S224 is performed; if the current frame interval is not less than the charging duration, step S225 is performed.

Step S224: Set the current frame interval to be no less than the charging duration.

The current frame interval is less than the charging duration, which means that when the terminal sends the second wireless frame, the energy storage element is not fully charged at this time. If the frame length of the second wireless frame is too long, it may cause the second wireless frame Failed to send. Therefore, the interval duration between the current frames can be set to be no less than the charging duration, so that when the terminal sends the second wireless frame, the energy storage element is fully charged, and the terminal can send the second wireless frame normally.

Step S225: Do not adjust the current frame interval.

The current frame interval is not less than the charging duration, which means that the terminal can send wireless frames normally at this time, so no adjustment is required.

In the above scheme, the current power supply capability information of the terminal is obtained, and the transmission parameters of the radio frame of the terminal are determined based on this, so that the current power supply capability information can realize the normal transmission of the radio frame without additional design of the circuit, The cost of the terminal is reduced and the competitiveness of the product is improved.

In one embodiment, whether to obtain the current power supply capability information of the terminal and its subsequent steps can be determined according to the current ambient temperature or the remaining power of the discharged power supply. In a specific implementation scenario, the step of obtaining the current power supply capability information of the terminal may be performed when the current ambient temperature is not greater than the preset temperature. The preset temperature is, for example, a certain temperature, such as 10 degrees Celsius, 5 degrees Celsius, and the like. When the energy storage element is a capacitor, the preset value may also be a temperature value corresponding to when the actual capacitance of the capacitor is a preset ratio of the nominal capacitance. The preset ratio is, for example, two-thirds, one-half, and so on. In another specific implementation scenario, the step of acquiring the current power supply capability information of the terminal may be performed when the remaining power of the discharged power supply is less than the preset power value. The preset power is, for example, half, one third, and so on, of the nominal capacity of the discharged power source.

In this way, by determining the specific conditions that need to acquire the current power supply capability information of the terminal, when the conditions are not met, the acquisition of the current power supply capability information of the terminal and its subsequent steps can be omitted, thereby reducing the energy consumption of the terminal and improving the battery life of the terminal. .
