Detailed Description
In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
In daily life, communication devices in common use are mainly portable communication devices, such as air conditioner remote controllers, car keys, and the like. Among them, the portable communication device has two main requirements, namely, the device is as small as possible in size, and the signal transmission distance is as far as possible. In order to ensure that the small size of the device is achieved, button cells are generally used as power supplies in the prior art, and in order to ensure that the signal transmission distance of the device can be far enough, a radio frequency amplifier is generally added in the prior art to amplify the wireless signal sent by the portable communication device.
For example, a typical 433MHz signal remote control emits a maximum power of approximately 13dbm, a maximum power consumption of approximately 23mA, and a transmission distance of approximately 100 m. On this basis, if it is desired to increase the transmission distance to 200m or more, it is necessary to add a radio frequency amplifier to enhance amplification of the radio signal emitted from the portable communication device, for example, to increase the maximum transmission power from 13dbm to 20dbm.
However, it should be noted that the power consumption of the rf amplifier is generally high, and the maximum pulse current of the coin cell is relatively small, for example, the power consumption of a common rf amplifier is about 72mA, and the maximum pulse current of the coin cell is only 15mA. Therefore, in the actual use process, the button battery often cannot meet the power consumption requirement of the radio frequency amplifier, so that the radio frequency amplifier cannot successfully strengthen the wireless signal, and the emission efficiency of the wireless signal is further affected.
In addition, since the lithium battery has a large volume, if a lithium battery having a larger pulse current is selected as a power supply, there is a problem in that the device volume of the portable communication device increases.
In order to solve the above-described problems, the embodiments of the present application provide an embodiment of a wireless signal transmission method, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different from that herein.
Fig. 1 is a flowchart of an alternative method for transmitting wireless signals according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:
step S101, detecting whether the operating voltage of the power supply in the communication device is within a preset range.
In step S101, the preset range is a working voltage interval of the power supply in a normal working state, and the power supply capacity of the power supply is smaller than the preset power supply capacity.
Optionally, the above communication device is a common portable communication device, for example, a communication device such as a television remote controller, an air conditioner remote controller, and a car key, and the portable communication device generally has a small device size. The power supply is a button battery.
In an alternative embodiment, fig. 2 shows a circuit configuration diagram of a wireless signal transmitting apparatus according to an embodiment of the present application. In fig. 2, the wireless signal device includes a single chip microcomputer U1, a button cell J1, a first MOS transistor Q1, a second MOS transistor Q2, a radio frequency amplifier PA, a target capacitor C1, and a load capacitor R. The single chip microcomputer U1 can be used as an execution main body of the wireless signal transmitting method in the embodiment of the application.
Specifically, after the button cell J1 is connected to the circuit, the single-chip microcomputer U1 enters the working state, meanwhile, the single-chip microcomputer U1 detects the working voltage of the button cell J1 in the circuit through the ADC1 data pin, and judges whether the working voltage is within a preset range, wherein the preset range is a working voltage interval of the button cell J1 in a normal working state, in other words, when the working voltage of the button cell J1 is within the preset range, it is indicated that the button cell J1 is in the normal working state, and if the working voltage of the button cell J1 is outside the preset range, it is indicated that the button cell J1 is in the abnormal working state. The preset range of the button cell J1 is typically 2.8V-3.3V.
Step S102, when the working voltage is in a preset range, the power supply is controlled to charge the target energy storage unit.
In step S102, the target energy storage unit may be the target capacitor C1 in fig. 2, as shown in fig. 2, when the singlechip U1 detects that the working voltage of the button cell J1 is within the preset range, the singlechip U1 will close the second MOS transistor Q2 in the circuit and simultaneously open the first MOS transistor Q1. Since the first MOS transistor is used to control the on relationship between the target capacitor C1 and the button cell J1, the button cell J1 charges the target capacitor C1 after the first MOS transistor Q1 is turned on. It should be noted that, the target energy storage unit may be a capacitor, and may also be other components with an energy storage function, so that for convenience in describing the technical solution of the embodiment of the present application, the description will be given below taking the target energy storage unit as an example of the target capacitor.
Step S103, detecting whether the current electric quantity stored by the target energy storage unit is greater than or equal to the target electric quantity.
In step S103, as shown in fig. 2, when the button cell J1 charges the target capacitor C1, the single chip microcomputer U1 detects the current electric quantity stored in the target capacitor C1 through the other data pin ADC2, and detects whether the current electric quantity stored in the target capacitor C1 is greater than or equal to the target electric quantity.
Step S104, when the current electric quantity is greater than or equal to the target electric quantity, a signal transmission instruction is received, and the target energy storage unit is controlled to supply power for the radio frequency amplifier, so that the radio frequency amplifier can enhance the signal intensity of the wireless signal corresponding to the signal transmission instruction.
In step S104, as shown in fig. 2, after a period of time has elapsed, if the single-chip microcomputer U1 detects that the current electric quantity of the target capacitor C1 is greater than or equal to the target electric quantity, it indicates that the communication device has a condition for transmitting a high-power wireless signal. If the singlechip U1 receives an external trigger signal and needs to transmit a wireless signal (for example, a portable alarm help seeker, when a user presses a button, the alarm help seeker needs to be sent to remote receiving equipment), the singlechip U1 controls the first MOS tube Q1 to be closed, and the second MOS tube Q2 to be opened, and because the second MOS tube Q2 is used for controlling the connection relation between the target capacitor C1 and the radio frequency amplifier PA, after the second MOS tube Q2 is opened, the target capacitor C1 can supply power for the radio frequency amplifier PA in a transient and high-power mode so as to meet the power consumption required by the radio frequency amplifier PA.
Step S105, controlling the communication device to transmit the wireless signal with enhanced signal strength.
In step S105, as shown in fig. 2, the rf amplifier PA enhances the signal strength of the wireless signal, so as to ensure that the wireless signal can be transmitted to a greater distance. The singlechip U1 controls the communication equipment to transmit the wireless signals with enhanced signal strength.
Based on the foregoing disclosure of steps S101 to S105, in this application, a manner of charging the target energy storage unit by the power supply and discharging the power supply by the target energy storage unit to supply power to the radio frequency amplifier is adopted, whether the working voltage of the power supply in the communication device is within a preset range is detected first, then when the working voltage is within the preset range, the power supply is controlled to charge the target energy storage unit, meanwhile, whether the current electric quantity stored in the target energy storage unit is greater than or equal to the target electric quantity is detected, and when the current electric quantity is greater than or equal to the target electric quantity, a signal transmitting instruction is received, the target energy storage unit is controlled to supply power to the radio frequency amplifier, so that the radio frequency amplifier performs enhancement of signal intensity on a radio signal corresponding to the signal transmitting instruction, and finally, the communication device is controlled to transmit the radio signal with enhanced signal intensity.
As can be seen from the foregoing, first, the present application does not directly supply power to the rf amplifier using the power supply device having the power supply capability smaller than the preset power supply capability, but uses the target energy storage unit to supply power to the rf amplifier. On this basis, this application is through keeping the charging to target energy storage unit when power supply unit's operating voltage is in preset range to constantly promote the storage electric quantity of target energy storage unit, then when target energy storage unit's storage electric quantity is greater than target electric quantity, carry out high-power electric quantity supply for radio frequency amplifier through target energy storage unit, thereby guaranteed that radio frequency amplifier can be successful carry out enhancement processing to radio signal, and then improved radio signal's transmission efficiency. In addition, since the capacitor is small in size, the space required is small, and thus the effect of avoiding an increase in the size of the portable communication device as much as possible is also achieved.
Therefore, the technical scheme of the application achieves the purpose of ensuring that enough electric quantity is provided for the radio frequency amplifier under the condition of not increasing the volume of the communication equipment, thereby realizing the technical effect of improving the success rate of the radio frequency amplifier when carrying out signal enhancement processing on the wireless signal, and further solving the technical problem of low wireless signal emission efficiency of the communication equipment caused by insufficient power supply capacity of the power supply in the prior art.
In an alternative embodiment, before detecting whether the current electric quantity stored by the target energy storage unit is greater than the target electric quantity, the singlechip acquires the minimum working electric quantity of the radio frequency amplifier, and determines the target electric quantity according to the minimum working electric quantity.
Alternatively, the target power may be determined based on a minimum operating power of the rf amplifier, where the target power is required to be greater than or equal to the minimum operating power.
In addition, the technician can directly input the minimum working electric quantity of the radio frequency amplifier into the singlechip, so that the singlechip can determine the target electric quantity according to the minimum working electric quantity of the radio frequency amplifier. The singlechip can also determine the minimum working electric quantity of the radio frequency amplifier according to the working state of the radio frequency amplifier in the use process of the communication equipment, and further determine the target electric quantity, for example, the singlechip defaults the minimum working electric quantity of the radio frequency amplifier to be the A electric quantity at first, and sets the target electric quantity to be the A electric quantity, if the singlechip detects that the power consumption requirement of the radio frequency amplifier still cannot be met when the stored electric quantity of the target capacitor is stored to the A electric quantity, the singlechip can adjust the minimum working electric quantity of the radio frequency amplifier, for example, the adjusted minimum working electric quantity is the (A+B) electric quantity, wherein B is a numerical value larger than 0. The power consumption requirement of the radio frequency amplifier can be met by continuously adjusting until the singlechip detects that the stored electric quantity of the target capacitor is stored to the target electric quantity.
In an alternative embodiment, the singlechip controls the power supply to charge the target capacitor when the operating voltage of the power supply is within a preset range. Specifically, the single chip microcomputer controls the first switch to enter an on state, the second switch enters an off state so that a circuit between the target energy storage unit and the power supply is connected, the power supply charges the target energy storage unit, the first switch is used for controlling the connection relation between the power supply and the target energy storage unit, and the second switch is used for controlling the connection relation between the target energy storage unit and the radio frequency amplifier.
Specifically, the first switch is the first MOS transistor Q1 in fig. 2, and the second switch is the second MOS transistor Q2 in fig. 2. It should be noted that the first switch and the second switch may be MOS transistors, or may be other switching devices, which is not particularly limited in this application.
In an alternative embodiment, when the power supply device charges the target capacitor, the singlechip also detects a voltage value of the power supply, outputs pulse waves to the first switch through a PWM interface on the singlechip according to the voltage value, and finally controls the opening time of the first switch according to the pulse waves to control charging current when the power supply charges the target energy storage unit.
Specifically, when the voltage value is larger than a preset safety voltage, the singlechip increases the duty ratio of the pulse wave to increase the opening time of the first switch, wherein the preset safety voltage is a normal working voltage corresponding to the singlechip; when the voltage value is smaller than the preset safety voltage, the singlechip reduces the duty ratio of the pulse wave so as to reduce the opening time of the first switch.
Optionally, as shown in the circuit design of fig. 2, when the singlechip U1 detects that the working voltage of the button battery J1 is within the preset range, the singlechip U1 closes the second MOS transistor Q2, and sets the general purpose input interface GPIO1 to a PWM mode to control the first MOS transistor Q1 to be opened, so that the singlechip U1 controls the button battery J1 to charge the target capacitor C1 according to the frequency of 1 MHz. The general purpose input interface GPIO1 can control the on time of the first MOS transistor Q1 by inputting pulse waves with different duty ratios to the first MOS transistor Q1 in the PWM mode, thereby achieving the purpose of controlling the charging current.
For example, when the singlechip U1 detects that the charging current of the button battery J1 for charging the target capacitor C1 is too large through the data pin ADC1, in order to avoid that other components such as the singlechip cannot work normally due to too low voltage pull of the button battery J1, the singlechip U1 inputs a pulse wave with a smaller duty ratio (i.e. reduces the duty ratio of the pulse wave) to the first MOS transistor Q1 through the general input interface GPIO1, thereby reducing the opening time of the first MOS transistor Q1 and further reducing the charging energy of the target capacitor C1.
When the singlechip U1 detects that the charging current of the button battery J1 for charging the target capacitor C1 is too small through the data pin ADC1, and the voltage value of the button battery J1 is larger than the preset safety voltage, in order to improve the charging efficiency, the singlechip U1 can input a pulse wave with a larger duty ratio (namely, the duty ratio of the pulse wave is increased) to the first MOS tube Q1 through the general purpose input interface GPIO1, so that the opening time of the first MOS tube Q1 is increased, and the charging of the target capacitor C1 is accelerated.
Therefore, the singlechip U1 dynamically adjusts the duty ratio of the pulse wave according to the voltage value of the power supply voltage and the preset safety voltage, so that the purpose of controlling the opening time of the first MOS tube Q1 is achieved, the effect of controlling the charging current of the power supply when the target energy storage unit is charged is achieved, and the charging current of the power supply when the target capacitor is charged is ensured to be always kept within a reasonable range.
In an alternative embodiment, when the working voltage of the power supply is lower than the minimum value of the preset range, the singlechip controls the first switch to enter a closed state and generates first alarm information, wherein the first alarm information is used for prompting a target object to charge or replace the power supply; when the working voltage of the power supply is higher than the maximum value of the preset range, the singlechip controls the first switch to enter the off state and generates second alarm information, wherein the second alarm information is used for prompting the abnormal occurrence of the circuit connection state of the power supply of the target object.
It should be noted that the preset range is an operating voltage range of the button cell in a normal operating state, in other words, if the operating voltage of the button cell is out of the preset range, it indicates that the button cell is in an abnormal operating state. Specifically, if the working voltage of the button cell is lower than the minimum value in the preset range, it indicates that the electric quantity of the button cell is insufficient and cannot meet the requirement of normal working, so that the singlechip firstly controls the first switch to enter a closed state so as to avoid further loss of the electric energy of the button cell, and then the singlechip also generates first prompt information so as to remind a target object using communication equipment of timely charging or replacing the button cell.
In addition, if the operating voltage of the button cell is greater than the maximum value of the preset range, it indicates that the circuit connection of the button cell is abnormal, for example, a problem of short circuit occurs. In order to avoid damaging other components of the communication equipment, the singlechip also controls the first switch to enter a closed state, so that the communication relation between the target capacitor and the button cell is cut off, and the effect of protecting the target capacitor is realized. And then the singlechip also generates second prompt information so as to remind the target object of abnormal circuit connection state of the power supply. The first prompt information and the second prompt information may be various types of prompt information, including but not limited to voice prompt information, light prompt information, and the like.
In an alternative embodiment, when the singlechip controls the target capacitor to supply power to the radio frequency amplifier, the singlechip controls the second switch to be in an on state, and the first switch is in an off state, so that a circuit between the target energy storage unit and the radio frequency amplifier is connected, and the target energy storage unit supplies power to the radio frequency amplifier.
In an alternative embodiment, when the current electric quantity of the target energy storage unit is smaller than or equal to the target electric quantity and a signal transmission instruction is received, the singlechip detects the charging rate of the target energy storage unit, calculates a difference value between the target electric quantity and the current electric quantity, and finally determines a waiting duration according to the difference value and the charging rate, wherein the waiting duration is the remaining duration from the current electric quantity to the target electric quantity of the target energy storage unit.
Optionally, the singlechip may calculate the charging rate of the target capacitor according to the increased electric quantity of the target energy storage unit in a preset time period and the duration of the preset time period, where the preset time period may be set in a self-defined manner, for example, a previous minute of the current time.
In an optional embodiment, after determining the waiting duration according to the difference value and the charging rate, the singlechip may generate third prompting information according to the waiting duration, where the third prompting information is used to remind the target object to resend the signal transmitting instruction after the waiting duration.
It should be noted that, for some specific portable communication devices, after determining the waiting time period according to the difference value and the charging rate, the single chip microcomputer may automatically control the communication device to retransmit the wireless signal after reaching the waiting time period. For example, for a portable alarm help-seeking device, when a user presses a button to send an alarm help-seeking message to a remote receiving device, if the radio frequency amplifier fails to strengthen a wireless signal due to the fact that the electric quantity of a target capacitor does not reach the target electric quantity in the first sending, after the singlechip determines a waiting time according to the charging rate of the target capacitor, the current electric quantity of the target capacitor and the target electric quantity, when the waiting time is reached, the singlechip automatically resends the alarm help-seeking message to the remote receiving device, and the sent wireless signal can be successfully strengthened by the radio frequency amplifier.
As can be seen from the foregoing, first, the present application does not directly supply power to the rf amplifier using the power supply device having the power supply capability smaller than the preset power supply capability, but uses the target energy storage unit to supply power to the rf amplifier. On this basis, this application is through keeping the charging to target energy storage unit when power supply unit's operating voltage is in preset range to constantly promote the storage electric quantity of target energy storage unit, then when target energy storage unit's storage electric quantity is greater than target electric quantity, carry out high-power electric quantity supply for radio frequency amplifier through target energy storage unit, thereby guaranteed that radio frequency amplifier can be successful carry out enhancement processing to radio signal, and then improved radio signal's transmission efficiency. In addition, since the capacitor is small in size, the space required is small, and thus the effect of avoiding an increase in the size of the portable communication device as much as possible is also achieved.
Example 2
The embodiment of the application provides a wireless signal transmitting system. Wherein fig. 3 is a schematic diagram of an alternative wireless signal transmission system according to an embodiment of the present application. As shown in fig. 3, the wireless signal transmission system at least includes: the power supply, the first switch, the second switch, the target energy storage unit, the radio frequency amplifier and the singlechip.
Specifically, in the wireless signal transmitting system, a power supply is connected with the singlechip and the target energy storage unit and is used for supplying power to the singlechip and the target energy storage unit, wherein the power supply capacity of the power supply is smaller than the preset power supply capacity;
the singlechip is used for detecting whether the working voltage of the power supply is in a preset range, and controlling the power supply to charge the target energy storage unit and controlling the charging current when the power supply charges the target energy storage unit when the working voltage is in the preset range, wherein the preset range is a working voltage interval of the power supply in a normal working state;
the singlechip is also used for detecting whether the current electric quantity stored by the target energy storage unit is larger than the target electric quantity or not, and controlling the target energy storage unit to supply power for the radio frequency amplifier according to the received signal transmission instruction under the condition that the current electric quantity is larger than or equal to the target electric quantity;
The radio frequency amplifier is connected with the target energy storage unit and used for enhancing the signal intensity of the wireless signal corresponding to the signal transmission instruction.
In addition, the first switch is connected with the singlechip, the power supply and the target energy storage unit and is used for controlling the connection relation between the power supply and the target energy storage unit according to a control instruction sent by the singlechip; the second switch is connected with the singlechip, the target energy storage unit and the radio frequency amplifier and is used for controlling the connection relation between the target energy storage unit and the radio frequency amplifier according to a control instruction sent by the singlechip.
In an alternative embodiment, the communication device is a common portable communication device, such as a television remote controller, an air conditioner remote controller, and a car key, and the portable communication device is generally characterized by a small size. The power supply is a button battery.
As shown in fig. 3, after the button cell is connected to the circuit, the single-chip microcomputer enters the working state, and at the same time, the single-chip microcomputer detects the working voltage of the button cell in the circuit through the ADC1 data pin and judges whether the working voltage is within a preset range, wherein the preset range is a working voltage interval of the button cell in a normal working state, in other words, when the working voltage of the button cell is within the preset range, it is indicated that the button cell is in the normal working state, and if the working voltage of the button cell is outside the preset range, it is indicated that the button cell is in an abnormal working state. The preset range of button cells is typically 2.8V-3.3V.
When the singlechip detects that the working voltage of the button battery is in a preset range, the singlechip turns off the second switch in the circuit and simultaneously turns on the first switch, and the first switch is used for controlling the connection relation between the target capacitor and the button battery, so that the button battery charges the target capacitor after the first switch is turned on.
Further, when the button battery charges the target capacitor, the singlechip detects the current electric quantity stored in the target capacitor through the other data pin ADC2, and detects whether the current electric quantity stored in the target capacitor is larger than or equal to the target electric quantity.
Optionally, after a period of time of charging, if the singlechip detects that the current electric quantity of the target capacitor is greater than or equal to the target electric quantity, the condition that the communication equipment transmits the high-power wireless signal is indicated. If the singlechip receives an external trigger signal and needs to transmit a wireless signal (for example, a portable alarm help seeker, when a user presses a button, the alarm help seeker needs to be sent to remote receiving equipment), the singlechip controls the first switch to be closed, and the second switch to be opened, and because the second switch is used for controlling the connection relation between the target capacitor and the radio frequency amplifier, the target capacitor can supply power for the radio frequency amplifier in a transient high power mode after the second switch is opened, so that the power consumption required by the radio frequency amplifier is met.
Finally, since the rf amplifier enhances the signal strength of the wireless signal, it is possible to ensure that the wireless signal can be transmitted to a greater distance. The singlechip finally controls the communication equipment to transmit the wireless signals with the enhanced signal strength.
As can be seen from the foregoing, first, the present application does not directly supply power to the rf amplifier using the power supply device having the power supply capability smaller than the preset power supply capability, but uses the target energy storage unit to supply power to the rf amplifier. On this basis, this application is through keeping the charging to target energy storage unit when power supply unit's operating voltage is in preset range to constantly promote the storage electric quantity of target energy storage unit, then when target energy storage unit's storage electric quantity is greater than target electric quantity, carry out high-power electric quantity supply for radio frequency amplifier through target energy storage unit, thereby guaranteed that radio frequency amplifier can be successful carry out enhancement processing to radio signal, and then improved radio signal's transmission efficiency. In addition, since the capacitor is small in size, the space required is small, and thus the effect of avoiding an increase in the size of the portable communication device as much as possible is also achieved.
Therefore, the technical scheme of the application achieves the purpose of ensuring that enough electric quantity is provided for the radio frequency amplifier under the condition of not increasing the volume of the communication equipment, thereby realizing the technical effect of improving the success rate of the radio frequency amplifier when carrying out signal enhancement processing on the wireless signal, and further solving the technical problem of low wireless signal emission efficiency of the communication equipment caused by insufficient power supply capacity of the power supply in the prior art.
