Description

Technical Field

[0001] This invention relates to the field of charging, and more particularly to a microphone charging method, system, device, and storage medium. Background Technology

[0002] In wireless microphone systems, transmitters and receivers are often used separately. Transmitters are typically mobile and need to be small and lightweight (e.g., a lapel clip), while receivers are fixed to recording or video equipment (cameras, mobile phones, etc.). The size and weight of the transmitter are less critical. Due to size limitations, microphone transmitters use small-capacity batteries with limited battery life. Traditional microphone charging methods involve using a charger or charging case, which is cumbersome and doesn't meet the portability requirements. Therefore, portable microphone charging solutions have emerged. However, portable charging often results in situations where the transmitter is out of power while the receiver still has power, or vice versa, leading to inconsistent battery life and a poor user experience. To address this technical issue of uneven battery life during charging, a new microphone charging technology is needed. Summary of the Invention

[0048] This invention provides a microphone charging method, system, device, and storage medium.

[0049] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0050] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 One embodiment of the microphone charging method in this invention is applied to a microphone charging system, which includes: N power transmitting systems and a power receiving system, where N is a positive integer. The microphone charging method includes:

[0051] 101. The i-th power transmitting system reads the i-th residual power value and the i-th operating current value based on a preset i-th coulomb meter, and sends the i-th residual power value and the i-th operating current value to the power receiving system, where i = 1, 2, 3, ..., N;

[0052] 102. The power receiving system receives the i-th power residual value and the i-th operating current value, and obtains the i-th transmission duration based on the i-th power residual value and the i-th operating current value;

[0053] 103. Based on the preset receiving coulomb fuel meter, read the remaining receiving power value and the receiving operating current value, and obtain the receiving battery life based on the remaining receiving power value and the receiving operating current value;

[0054] In steps 101-103, the power transmitting system is the default device that transmits electrical energy to the power receiving system. In the microphone, this can be either a transmitter or a system consisting of a transmitter and an external battery. The power receiving system is primarily a microphone receiver, which can also be connected to an external battery to form a system. The received electrical energy can be stored either in its own battery or in an external battery.

[0055] The N power transmitting systems can use multiple charging modules during the microphone charging process. Each charging module has a coulomb meter to calculate its own power and operating current. The present invention does not limit the number of charging transmitters. The coulomb meter can be referenced from... Figure 2 , Figure 2 This is a schematic diagram illustrating the principle of a coulomb meter. The operating principle of coulomb metering involves connecting a sampling resistor (R) along the battery's charging / discharging path. s An analog-to-digital converter (ADC) measures the voltage across the sense resistor and converts it into a current value indicating whether the battery is charging or discharging. A real-time counter (RTC) then integrates this current value over time to determine the amount of coulombs flowing. The battery capacity can be calculated based on the following integral:

[0056] Where Q is the battery capacity in Ah; t is the operating time of the fuel gauge in hours; I s (t) Current flowing through the sampling resistor, in A; R s The sampling resistor value is expressed in Ω; V s (t) represents the ADC sampling voltage in V.

[0057] Similarly, the power receiving system also has a coulomb meter to calculate the remaining value of the received power and the receiving operating current value in the power receiving system. Based on the duration calculation formula T = Q / I, the endurance of each system is calculated, where T is the duration, Q is the charge amount, and I is the current value.

[0058] 104. Determine whether the i-th transmission duration is less than the reception duration;

[0059] In this embodiment, the battery life of each transmitter and receiver is determined separately, and the transmitter with shorter battery life is charged.

[0060] 105. If the transmission duration of the i-th power transmission system is not less than the reception duration, then a positive charging command is sent to the i-th power transmission system.

[0061] 106. The i-th power transmitting system receives the forward charging command and transmits power to the power receiving system according to the forward charging command.

[0062] In steps 105-106, the system or machine with a shorter battery life is charged. First, they communicate with each other to determine the current transmission mode. Then, the power transmitting system directly transmits the power to the power receiving system to complete the first AC charging. Then, the cycle 101-104 is repeated every fixed time to ensure the stability between battery lifespans. That is, the power is transmitted from the machine or system with a longer battery life to the machine or system with a shorter battery life.

[0063] Furthermore, in step 106, the following steps can be performed:

[0064] 1061. Based on the preset battery life balancing algorithm and the forward charging command, perform forward battery calculation on the i-th battery remaining value, the i-th working current value, the receiving battery remaining value, the receiving working current value, the i-th transmitting battery life, and the receiving battery life to obtain the i-th forward charging battery.

[0065] 1062. Transmit the electrical energy of the i-th positive charging charge to the electrical energy receiving system.

[0066] In steps 1061-1062, the i-th power transmitting system TX starts charging the power receiving system RX. To ensure that the power transmitting system TX and the power receiving system RX have the same range after charging is completed, and considering the charging efficiency of the power transmitting system TX and the power receiving system RX, the following set of equations holds.

[0067] T R =Q R / I R

[0068] T T =Q T / I T

[0069]

[0070] Among them, Q T Let I be the residual value of the i-th battery charge. T Let I be the residual value of the i-th battery charge. R To receive the operating current value, Q R To receive the remaining battery power, Q RR T is reserved for receiving power. T For the i-th launch endurance, T R To extend the battery life, the power transmission system TX supplies the power receiving system RX with a charging amount Q. RC Let n be the charging efficiency for forward charging calculated based on hardware parameters, and let Q be the amount of charge Q for the i-th forward charge. RCThe power receiving system RX can precisely control the charging amount of the power transmitting system TX through its own fuel gauge, ensuring that the power transmitting system TX and the power receiving system RX have the same battery life after charging is completed.

[0071] Furthermore, when i is 1, the following steps can be performed at 1061:

[0072] 10611, Q RC =(Q RR / I R -Q T / I T )*n*I T =Q R -Q RR , where Q RC For the first positive charge, Q T I is the first remaining charge value. T Q is the first operating current value. R To receive the remaining battery power, Q RR To reserve a value for receiving power, I R The receiving current value is denoted by n, which represents the forward charging efficiency calculated based on hardware parameters.

[0073] In step 10611, the equation is actually the non-hidden solution to the system of equations. If there are multiple systems, the hidden solution needs to be expressed in linear algebra.

[0074] Furthermore, after step 106, the following steps can also be performed:

[0075] 107. If the transmission duration of the i-th power generation system is less than the reception duration, then a negative charging command is sent to the i-th power transmission system.

[0076] 108. The i-th power transmitting system receives a negative charging command and sends a negative power confirmation message to the power receiving system;

[0077] 109. The power receiving system receives the power negative confirmation information and transmits power to the i-th power transmitting system.

[0078] In steps 107-109, the forward charging process is the process by which the power transmitting system charges the power receiving system, and the reverse charging process is the process by which the power receiving system charges the power transmitting system in the opposite direction.

[0079] In fact, the process of reverse charging, whether it is forward charging or reverse charging, requires calculating the amount of charge transferred.

[0080] Furthermore, "transmitting electrical energy to the i-th electrical energy transmission system" can be performed by the following steps:

[0081] 1091. According to the preset battery life balancing algorithm, perform negative battery calculation on the i-th battery residual value, the i-th working current value, the receiving battery residual value, the receiving working current value, the i-th transmitting battery life, and the receiving battery life to obtain the i-th reverse charging battery.

[0082] 1092. Transmit the electrical energy of the i-th reverse charging quantity to the i-th electrical energy transmission system.

[0083] In steps 1091-1092, the power transmission system RX begins charging the i-th power transmission system TX. To ensure that the battery life of the power transmission system RX and the i-th power transmission system after charging TX is the same, and considering the charging efficiency of the power transmission system RX charging the i-th power transmission system TX, the following set of equations holds:

[0084] T R =Q R / I R

[0085] T T =Q T / I T

[0086]

[0087] Among them, Q T Let I be the residual value of the i-th battery charge. T Let I be the residual value of the i-th battery charge. R To receive the operating current value, Q R To receive the remaining battery power, T T For the i-th launch endurance, T R To receive battery life data, Q RR Q is a reserved value for receiving power. TC Let Q be the amount of reverse charging of the i-th power, and n be the charging efficiency of forward charging calculated based on hardware parameters. The amount of reverse charging of the i-th power is calculated by solving for Q. TC The power receiving system RX can precisely control the charging amount of the power transmitting system TX through its own fuel gauge, ensuring that the power transmitting system TX and the power receiving system RX have the same battery life after charging is completed.

[0088] Furthermore, when i is 1, the following steps can be performed at position 1091:

[0089] 10911, Q TC =(Q RR / I R -Q T / I T )*n*IT =Q R -Q RR , where Q TC For the first reverse charge, Q T I is the first remaining charge value. T Q is the first operating current value. R To receive the remaining battery power, Q RR To reserve a value for receiving power, I R The receiving current value is denoted by n, which represents the reverse charging efficiency calculated based on hardware parameters.

[0090] In step 10911, the equation is actually the non-hidden solution to the system of equations in step 1091. However, if there are multiple systems, the hidden solution needs to be expressed in linear algebra.

[0091] Furthermore, the reverse charging 109 can also perform the following steps:

[0092] 1092. Establish linear constraint equations:

[0093] T R =Q R / I R ;

[0094] T Tj =Q Tj / I Tj (j=1, 2, 3,…,i,…,N);

[0095] Q RR / I R =T Tj +Q TjC / (n*I Tj ), (j=1, 2, 3,...,i,...,N);

[0096] Q RR +∑Q TjC =Q R ;

[0097] Among them, Q RR Q is a reserved value for receiving power. R To receive the remaining battery power, I R To receive the operating current value, I Tj Let Q be the j-th operating current value. Tj Let ∑Q be the residual value of the j-th power. TjC Let Q be the sum of the reverse charging power of the j-th power transmission system, n be the reverse charging efficiency calculated based on hardware parameters, and Q be the total reverse charging power. TjC T represents the reverse charging amount of the j-th power transmission system. Tj For the j-th launch endurance, T RTo receive the battery life, j takes a value from 1 to N;

[0098] 1093. Solve the linear constraint equation to obtain the amount of reverse charging of the i-th charge.

[0099] In steps 1092-1093, to explain the N generalized operations, we will illustrate the reverse charging process when N is 2. Here, TX1 represents the first energy transmitting system, TX2 represents the second energy transmitting system, and RX represents the energy receiving system. The following steps are performed:

[0100] S1, TX1, and TX2 obtain their remaining battery power Q. T1 Q T2 Operating current I T and transmit it to RX;

[0101] S2 and RX calculate their own remaining power and obtain the normal operating current Q of TX1 and TX2. RR Q T1 Q T2 I R I T1 I T2 ;

[0102] S3, The charging efficiency calculation module calculates the charging efficiency n during the charging process;

[0103] S4. Based on the remaining battery power of the transmitter and receiver, the operating current of the transmitter and receiver, and the charging efficiency of the transmitter and receiver, calculate the remaining battery life T of RX, TX1, and TX2. R T T1 and T T2。

[0104] T R =Q R / I R

[0105] T T1 =Q T1 / I T1

[0106] T T2 =Q T2 / I T2

[0107] S5, if T T1 ≥T R ≥T T2 Or T T2 ≥T R ≥T T1 The RX only needs to charge one TX; the method for charging one TX can be referenced. If T R ≥T T1≥T T2 The charging balancing method is as follows:

[0108] S4' and RX need to charge TX1 and TX2 simultaneously. In order to ensure that the battery life of RX, TX1 and TX2 is the same after charging is completed, and considering the charging efficiency of RX to TX, the following set of equations holds.

[0109]

[0110] Among them, Q RR The power reserved for charging TX from RX is expressed in Ah; Q T1C Q represents the first reverse charge amount of the first electrical energy transmission system; T2C The second reverse charging capacity of the second energy transmission system; n is the reverse charging efficiency calculated based on hardware parameters, Q. R The remaining value of the received power is the original value before the power is transmitted.

[0111] S5', By solving the problem, the amount of charge Q that RX provides to TX1 and TX2 can be obtained. T1C and Q T2C

[0112] S6' and RX can precisely control the amount of charge given to TX1 and TX2 through their own fuel gauges, ensuring that RX, TX1, and TX2 have the same runtime after charging. When the receiver charges the two transmitters, if T... T1 ≥T T2 ≥T R The receiver does not need to charge the transmitter, but instead starts forward charging to ensure that RX, TX1, and TX2 have the same battery life after charging is complete.

[0113] In this embodiment of the invention, when the charging modules are connected, the receiver charges multiple transmitters through a series of calculations. The amount of power charged is strictly controlled by calculation. After charging is completed, the receiver and multiple transmitters are guaranteed to have the same battery life. This avoids the situation where the receiver's own power is insufficient to support the simultaneous operation of the transmitter and transmitter after charging the transmitter, or the battery life is shorter than that of the transmitter, causing both the transmitter and the receiver to fall into a state of inoperability.

[0141] In this embodiment of the invention, when the charging modules are connected, the receiver charges multiple transmitters through a series of calculations. The amount of power charged is strictly controlled by calculation. After charging is completed, the receiver and multiple transmitters are guaranteed to have the same battery life. This avoids the situation where the receiver's own power is insufficient to support the simultaneous operation of the transmitter and transmitter after charging the transmitter, or the battery life is shorter than that of the transmitter, causing both the transmitter and the receiver to fall into a state of inoperability.
