For example, referring to fig. 1, a schematic view of a scenario of an electric quantity prompting method provided in an embodiment of the present application is shown. The scene comprises a control terminal 10 and a controlled terminal 20, wherein the main control terminal 10 and the controlled terminal 20 are connected through wireless communication to realize data interaction.

The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.
In the embodiment of the present application, description will be made from the perspective of a power prompting device, and the power prompting device may be specifically integrated in a computer device such as a terminal. Referring to fig. 3, fig. 3 is a schematic step flow diagram of an electric quantity prompting method provided in the embodiment of the present application, and when a processor on a terminal executes a program corresponding to the electric quantity prompting method, the specific flow of the electric quantity prompting method is as follows:
101. a target control signal is received.
The target control signal may be a control signal sent by the control terminal, and is used for controlling the controlled terminal, so that the controlled terminal executes a corresponding policy according to the target control signal. The target control signal may be an infrared control signal, a bluetooth wireless signal, or other control signals, which is not limited herein. The target control signal may be an analog signal, or may be a signal transmitted in the form of a waveform signal, or may be a signal transmitted in the form of a control code including a low-level signal and a high-level signal converted into a digital signal. For example, taking an infrared remote controller as a control terminal, the television apparatus is a controlled terminal, and the infrared remote controller controls the television apparatus by sending an infrared light control signal (target control signal), wherein the infrared control signal can be transmitted in a waveform signal form or a digital signal control code form.
102. The number of target low level signals in the target control signal is acquired.
In order to learn the amount of control signals actually contained by the target control signal, the error rate is calculated later. The present embodiment obtains the number of target signals of the target control signal, which may be a high level signal, a low level signal, a falling edge signal of a high level jump to a low level, a rising edge signal of a low level jump to a high level, or the like. It should be noted that, the controlled terminal generally only responds to a certain type of signal, that is, when the controlled terminal detects that the master terminal sends a certain type of signal, the controlled terminal responds to the signal and makes a corresponding policy. For example, the low-level signal is used as a response signal of the controlled terminal, and the number of the target low-level signals in the target control signal is obtained to determine the control signal quantity actually contained in the target control signal.
In some embodiments, the step of "obtaining the number of target low level signals in the target control signal" may include:
(1) The target control signal is converted into a waveform signal.
Wherein the low level signal belongs to a part of the waveform signal. In order to accurately acquire the number of low-level signals in the target control signal later, the present embodiment converts the received target control signal into a waveform signal. The conversion process of the waveform signal is as follows: extracting samples of the target control signal according to a preset interval time so that the continuous target control signal becomes a discrete signal; converting the samples of the target control signal into corresponding signal digital values representing the magnitudes of the decimated samples; the digital value of the signal is converted into a binary number and a waveform signal is determined from the binary number.
(2) The number of target low-level signals in the target control signal in the target period is acquired.
After the target period of the low-level signal in the target control signal is determined, the target period is taken as a time dimension, the number of the target low-level signals in the time dimension is acquired, and the accuracy of learning the number of the target low-level signals in the target control signal is improved.
The starting time of the target period is the starting trigger time of the first low-level signal in the waveform signal, and the ending time of the target period is the ending trigger time of the last low-level signal in the waveform signal.
In some embodiments, the step of "obtaining the number of the target low level signals in the target control signal in the target period" may include:
(2.1) identifying the starting trigger time and the ending trigger time of the target period in the waveform signal;
(2.2) obtaining the number of target low-level signals between the starting trigger time and the ending trigger time in the waveform signals.
When the number of low-level signals of the waveform signals corresponding to the target control signals is obtained, the target time period and the waveform signals can be combined, for example, the starting trigger time and the ending trigger time of the target time period are marked in the waveform signals, and the number of the target low-level signals between the starting trigger time and the ending trigger time in the waveform signals is counted. To improve the accuracy of the number of target signals from which the target control signal is derived.
In some embodiments, the determining of the target time period may include:
A. the start trigger time of the first low level signal in the read waveform signal and the end trigger time of the last low level signal in the read waveform signal.
The waveform signal comprises a plurality of low-level signals, the triggering sequence of the low-level signals in the waveform signal is progressive in sequence according to time and the sequence of the low-level signals in the waveform signal, and the triggering sequence of the low-level signals in the waveform signal is started to trigger by the first low-level signal until the last low-level signal. Wherein the trigger time of each low level signal in the waveform signal is different.
In order for the controlled terminal to distinguish the current target control signal from other control signals, it is necessary to predict a control period when the target control signal controls the controlled device. In this embodiment, the start trigger time of the first low level signal in the waveform signal and the end trigger time of the last low level signal in the waveform signal need to be read first, so that a control time period when the target control signal controls the controlled device is determined according to the start trigger time and the end trigger time of the low level signal in the waveform signal.
B. And determining a target period for triggering all the low-level signals according to the starting trigger time and the ending trigger time.
In order to predict a control time period when the target control signal controls the controlled device, the embodiment may determine a target time period for triggering all low level signals according to the start trigger time and the end trigger time of the low level signals in the waveform signal after acquiring the start trigger time and the end trigger time of the low level signals of the waveform signal corresponding to the target control signal. In this way, the control period when the target control signal controls the controlled device, that is, the target period when the target control signal actually contains the low-level signal, is determined.
Furthermore, in some embodiments, before the step of "obtaining the number of target low level signals in the target control signal", the method further includes:
receiving a control signal within a preset duration;
detecting the interval time between any two adjacent control signals when detecting that the number of the control signals in the preset duration is a plurality of;
obtaining a control signal corresponding to the interval time smaller than a preset time threshold value, and obtaining a control signal segment connected in series;
the control signal segment is determined as the target control signal.
The preset time length can be unit time set by user definition or unit time set by a controlled terminal in a factory, the preset time length is scalar data, and the controlled terminal starts timing when receiving a control signal for the first time until the preset time period is finished; the preset duration may be 3 seconds, 10 seconds, 1 minute, etc., and is not limited herein. For example, the preset duration is set to be 3 seconds, the controlled terminal is taken as television equipment, the infrared remote controller is taken as a main control terminal, when the television equipment receives an infrared light control signal sent by the infrared remote controller, timing is started until the preset duration is over, and control signals within 3 seconds are counted. It should be noted that, one key operation performed by the user on the infrared remote controller is regarded as a control signal, and it can be understood that when the user performs the key operation for multiple times within the preset duration, the television device receives the control signals for corresponding times, and the multiple control signals are regarded as one control flow of the user on the television device through the remote controller.
When a plurality of control signals are received within a preset time, in order to determine whether the plurality of control signals within the preset time belong to the same control flow, the embodiment forms a control signal pair from any two adjacent control signals based on the receiving sequence of the plurality of control signals, calculates the interval time between the two control signals in the control signal pair, and regards the control signal pair with the interval time smaller than the preset time threshold as the control signal in the same control flow, and forms a coherent control signal segment from a plurality of coherent control signal pairs with the interval time smaller than the preset time threshold, wherein the control signal segment is regarded as the target control signal of the same control flow.
By the method, after the target control signal is received, the number of target low-level signals in the target control signal is acquired, so that the control signal quantity actually contained in the target control signal is learned, and the error rate of the target control signal is calculated conveniently.
103. And decoding the target control signal to obtain the quantity of effective decoding information corresponding to the target control signal.
The effective decoding information is an information code which can be responded by the controlled terminal in the target control signal.
In order to determine the amount of effective decoding information contained in the target control signal, the embodiment of the present application decodes the target control signal to obtain target decoding information, and verifies the target decoding information to determine the amount of effective decoding information.
In some embodiments, the step of decoding the target control signal to obtain the amount of valid decoding information corresponding to the target control signal includes:
(1) Converting the target control signal into a waveform signal;
(2) Identifying a start low-level signal in the waveform signal, wherein the start low-level signal is a start signal of a low-level control signal section;
(3) Determining a corresponding low-level control signal segment in the waveform signal according to each initial low-level signal;
(4) Acquiring the trigger time of each low-level signal in the low-level control signal section, and acquiring the target interval time between two adjacent trigger times;
(5) Converting each target interval time into a corresponding signal value to obtain target decoding information corresponding to each low-level control signal segment;
(6) And checking the target decoding information to obtain the quantity of effective decoding information corresponding to the target decoding information.
The target decoding information is a control code obtained by decoding the received target control signal by the controlled terminal, and can be regarded as a control instruction, and the controlled terminal can identify the target decoding information so as to execute a corresponding strategy according to the identified target decoding information. For example, taking a television device as a controlled terminal, after receiving a target control signal sent by a remote control device, the television device decodes the target control signal to obtain corresponding target decoding information, and if the target decoding information is identified as a control code for switching channels, executes a strategy for switching to a target channel.
Because the target control signal can be composed of a control signal string, the target control signal can not directly control the controlled terminal, and the target control signal needs to be converted into a control code which can be responded by the controlled terminal. In this embodiment, after receiving the target control signal, in order to obtain target decoding information that the controlled terminal can respond to, the target decoding information may be decoded to obtain target decoding information corresponding to the target control signal.
It should be noted that each low level control signal segment is composed of an initial low level signal and a target level signal segment; the initial low-level signal can be an initial signal of a low-level control signal section and is used for distinguishing each low-level control signal section in the waveform signal; wherein the target level signal segment is composed of a plurality of low level signals, and the target level signal segment may be a main signal for controlling the controlled terminal.
Further, the corresponding target decoding information is obtained by decoding each low-level control signal segment in the waveform signal, wherein each low-level control signal segment corresponds to one target decoding information. For example, in this embodiment, taking RCA coding rule as an example, each control code may sequentially consist of 1 pilot code, 4 user codes, 8 data codes, 4 user code counter codes, and 8 data code counter codes, that is, each control code includes 25 digits; each code corresponds to a low level signal, or may be a trigger signal or a falling edge of 1 low level signal, for example, the 1 pilot code corresponds to a start low level signal in the low level control signal segment, and the user code, the data code, the user code counter code and the data code counter code collectively correspond to a target level signal segment in the level control signal segment, which is understood to include 24 low level signals, that is, the control code corresponding to one low level control signal segment is 25 digits. It should be noted that, 1 is a pilot code composed of a 4ms high level signal and a 4ms low level signal, and the composition forms of the user code, the data code, the user code inverse code and the data code inverse code may include: 500 mus high level signal +2.0ms low level signal composition, 500 mus high level signal +1.0ms low level signal composition.
In order to obtain the target decoding information in the target control signal, the present embodiment needs to decode the target control signal; the process of decoding the target control signal may be: converting the target control signal into a waveform signal; the method specifically includes identifying a start low-level signal in a waveform signal, wherein the start low-level signal can be a signal period of each high-low level signal in the waveform signal, identifying a continuous signal section consisting of a 4ms high-level signal with a signal period of 4ms low-level signal, and determining a low-level signal in the continuous signal section consisting of the 4ms high-level signal and the 4ms low-level signal as the start low-level signal; determining a level signal section formed by a high level signal and a low level signal with signal periods smaller than 4ms after the low level signal is started as a target level signal section; acquiring the trigger time of each low-level signal in the target level signal section, and according to the target interval time between two adjacent trigger times; and sequentially converting each target interval time into a corresponding signal value to obtain target decoding information corresponding to each low-level control signal segment.
Illustratively, the signal period of the pilot code is a 4ms high level signal and a 4ms low level signal composition, and the target level signal segment includes a plurality of different signal periods (500 μs high level signal+2.0 ms low level signal composition, 500 μs high level signal+1.0 ms low level signal composition). After the target control signal is converted into the waveform signal, a signal segment with a signal period of 4ms high level signal and 4ms low level signal in the waveform signal is used for determining the position of the initial low level. After the initial low-level signal is acquired, a signal segment with a signal period of 500 mu s high-level signal+2.0 ms low-level signal and a signal segment of 500 mu s high-level signal+1.0 ms low-level signal are determined as target level control signal segments, one low-level control signal segment is determined according to the initial low-level signal and the target level control signal segment, and then all low-level control signal segments in the waveform signal can be determined in the mode. Further, the triggering time of each low-level signal in the low-level control signal section is obtained, and the target interval time between two adjacent triggering times is obtained; converting each target interval time into a corresponding signal value, for example, when the pilot code is set, setting the signal value of which the target interval time is 8ms to be 1, and specifically setting the signal value according to actual conditions; when the signal values of the user code and the data code in the target level control signal section are set, the corresponding signal value with the target interval time of 2.5ms is set to be 1, and the corresponding signal value with the target interval time of 1.5ms is set to be 0; when the signal values of the user code inversion code and the data code inversion code in the target level control signal section are set, the corresponding signal value with the target interval time of 2.5ms is set to be 0, and the corresponding signal value with the target interval time of 1.5ms is set to be 1; the target decoding information obtained in this way is 1101001101000010110010111, wherein the first bit pilot code of the target decoding information is 1, the user codes 2 to 5 are 1010, the data codes 6 to 13 are 01101000, the user code inverse codes 14 to 17 are 0101, and the data code inverse codes 18 to 25 are 10010111. In this way, target decoding information corresponding to each low-level control signal segment is obtained.
When a user executes a key on the remote controller once, the control signal sent by the remote controller is decoded to obtain 2-4 key codes, namely 2-4 target decoding information; when the user continuously presses the key 3 times, the control signal segment corresponding to the target control signal consists of 3 control signals, and the target control signal can be decoded to obtain 6-12 target decoding information.
After the target control signal is obtained through decoding, because the control signal sent by the main control terminal is influenced by the electric quantity, the target decoding information obtained through decoding is wrong, and the controlled terminal cannot respond, so that the target decoding information obtained through decoding needs to be checked to determine effective decoding information which can be responded by the controlled terminal.
In some embodiments, the step of "checking the target decoding information to obtain the amount of valid decoding information corresponding to the target decoding information" may include:
(6.1) extracting the information code and the check code in each target decoding information according to a preset encoding rule;
(6.2) checking the information code according to the check code;
(6.3) when the information code and the check code in the target decoding information are symmetrical, determining the target decoding information with the symmetrical information code and the symmetrical check code as effective decoding information;
(6.4) acquiring the amount of effective decoding information.
The information codes are user codes and data codes in the target decoding information, and the check codes are user code reverse codes and data code reverse codes in the target decoding information.
In order to obtain effective decoding information in the target decoding information obtained by decoding, each target decoding information obtained by decoding needs to be checked. For example, taking an RCA encoding rule as a preset encoding rule as an example, identifying the target decoding information according to the RCA encoding rule, extracting an information code and a check code in the target decoding information, namely extracting a user code and a data code in the target decoding information, and extracting a user code inverse code and a data code inverse code in the target decoding information; the information code is checked according to the check code, for example, the user code is 1010, the data code is 01101000, the user code is 0101, the data code is 10010111, the user code 1010 is checked by the user code is 0101, the data code 01101000 is checked by the data code is 10010111 to determine whether the user code corresponds to the user code and whether the data code corresponds to the data code, when the user code corresponds to the user code and the data code corresponds to the data code, the information code and the check code are symmetrical in the target decoding information, and the target decoding information symmetrical to the information code and the check code is determined as effective decoding information.
Further, after the valid decoding information is determined in the above manner, the number of all valid decoding information is counted to determine the number of valid decoding information that the controlled terminal can respond to, and to determine the number of invalid control subcodes that the controlled terminal cannot respond to.
104. And determining the error rate of the target control signal according to the quantity of the effective decoding information and the quantity of the target low-level signals.
After decoding the target control signal, an error signal is generated due to the influence of low electric quantity on the main control terminal, so that the transmitted control signal has errors, and the target decoding information received by the controlled terminal has partial errors, for example, the number of low-level signals contained in a waveform signal corresponding to the target decoding information is increased or decreased, so that the controlled terminal is caused to be in error in decoding, that is, the target decoding information obtained by decoding the target control signal may contain effective decoding information and ineffective control subcode.
To determine whether the controlled terminal is fully responsive to the target control signal, the present embodiment may calculate whether the target control signal has an error rate. And determining the number of the effective low-level signals according to the number of codes of the effective decoding information and the preset signal quantity contained in each sub-code, and calculating the error rate according to the number of the effective low-level signals and the number of the target low-level signals, so as to determine whether the controlled terminal completely responds to the target control signal.
In some embodiments, the step of determining the bit error rate of the target control signal according to the amount of effective decoding information and the amount of the target low level signal may include:
determining the number of effective low-level signals corresponding to the effective decoding information according to the effective decoding information and a preset encoding rule;
and determining the error rate of the target control signal according to the number of the effective low-level signals and the number of the target low-level signals.
For example, taking the RCA coding rule as an example of a preset coding rule, since the RCA coding rule includes a 1-bit pilot code, a 4-bit user code, an 8-bit data code, a 4-bit user code inverse code, and an 8-bit data code inverse code for each control code, the effective decoding information in this embodiment includes 25 digits, and the low-level control signal segment corresponding to the effective decoding information includes 25 low-level signals. Further, the number of effective low-level signals corresponding to the coding number of the effective decoding information is determined based on the 25 low-level signals contained in each effective decoding information, and it is understood that the effective low-level signals are signals responded by the successfully controlled terminal.
Further, the bit error rate of the target control signal is determined according to the number of the effective low-level signals and the number of the target low-level signals. For example, the user operates the key for 5 times within the preset duration, each key corresponds to 3 pieces of target decoding information, the controlled terminal decodes to obtain 10 pieces of effective decoding information, and the waveform signal corresponding to the target control signal actually includes 388 pieces of target low-level signals (the sum of the falling edges is 388 times). When calculating the error rate of the target control signal, acquiring the number of the effective low levels corresponding to all the effective decoding information, determining an effective signal ratio according to the number of the effective low levels and the number of the target low levels, and determining the error rate according to the effective signal ratio; the bit error rate E of the target control signal is calculated as: e=1-25 x 10/388=35.57%, where E denotes the bit error rate, which is 35.57% for this example.
By the method, the error rate of the target control signal can be obtained, so that whether the target control signal has an error or not is determined, and whether the main control terminal is in a low-power state or not can be conveniently determined later.
105. When the error rate is detected to be larger than the preset error rate threshold value, generating electric quantity prompt information, and carrying out electric quantity prompt according to the electric quantity prompt information.
Because the main control terminal is affected by low electric quantity, an error signal can be generated, and thus, the sent control signal has errors, so that partial errors exist in target decoding information received by the controlled terminal, for example, the number of low-level signals contained in waveform signals corresponding to the target decoding information is increased or decreased, and then, the controlled terminal is caused to have errors in decoding. When the controlled terminal decodes the error, the error rate of the target control signal is calculated, and whether the target control signal has an error signal or not is determined according to the error rate of the target control signal. When the target control signal has a signal which cannot be responded by the controlled terminal, a corresponding preset strategy is made, such as electric quantity prompt of the main control terminal is carried out on a display interface of the controlled terminal, and prompt voice of the main control terminal in a low electric quantity state is sent out by the controlled terminal.
When determining whether the target control signal has an error signal according to the error rate of the target control signal, the calculated error rate may be compared with a preset error rate threshold, where the preset error rate threshold may be 0, 5%, 10%, and the like, and the method is not limited herein, and may be specifically determined according to practical situations. For example, in this embodiment, the preset bit error rate threshold is 0, when the bit error rate of the target control signal is calculated to be 35.57%, and when the calculated bit error rate is greater than the preset bit error rate threshold, it is indicated that the target control signal has an error signal; and then, judging that the electric quantity of the main control terminal is in a low-electric-quantity state, generating low-electric-quantity prompt information at the moment, and carrying out electric quantity prompt according to the electric quantity prompt information.
In some embodiments, after the step of determining the bit error rate of the target control signal according to the amount of effective decoding information and the amount of the target low level signal, the method further includes:
determining the bit error rate as a first bit error rate of a preset period when receiving a target control signal at intervals of unit time, and returning to the step of obtaining the number of target low-level signals in the target control signal to obtain a second bit error rate corresponding to current target control information;
Obtaining a target error rate according to the average value of the first error rate and the second error rate;
generating electric quantity prompt information when the error rate is detected to be larger than a preset error rate threshold value, wherein the electric quantity prompt information comprises the following steps:
and when the target bit error rate is detected to be larger than the preset bit error rate threshold value, generating electric quantity prompt information.
In order to improve accuracy in determining the state of charge of the master control terminal, in this embodiment, a target control signal is received and the bit error rate thereof is calculated; the target control signal is received again in the interval unit time, and in order to facilitate understanding, the target control signal received in the interval unit time is called a second target control signal, the first calculated error rate is determined as a first error rate, a second error rate corresponding to the second target control signal is calculated, and the target error rate is determined according to the average value of the first error rate and the second error rate; when the target error rate is larger than a preset error rate threshold value, determining that the electric quantity of the main control terminal is in a low electric quantity state; at this time, the power-down prompt message is generated, and the power prompt is performed according to the power prompt message.
In addition, in order to improve the accuracy of determining the state of charge of the master terminal, the state of charge of the master terminal can be determined by combining the error rates obtained by multiple calculations. For example, receiving a target control signal and calculating a first error rate; calculating a second error rate when receiving the target control signal at intervals of unit time; calculating a third error rate when the target control signal is received again at intervals of unit time; comparing the first error rate, the second error rate and the third error rate with preset error rate thresholds respectively, and when a plurality of error rates are larger than the preset error rate thresholds, determining that the electric quantity of the main control terminal is in a low electric quantity state; at this time, the power-down prompt message is generated, and the power prompt is performed according to the power prompt message.
From the above, the embodiments of the present application may receive a target control signal; acquiring the number of target low-level signals in a target control signal; decoding the target control signal to obtain the quantity of effective decoding information corresponding to the target control signal; determining the error rate of the target control signal according to the quantity of the effective decoding information and the quantity of the target low-level signals; when the error rate is detected to be larger than the preset error rate threshold value, generating electric quantity prompt information, and carrying out electric quantity prompt according to the electric quantity prompt information. According to the embodiment of the application, the controlled terminal can determine the corresponding error rate according to the target control signal sent by the main control terminal, so that the electric quantity state of the main control terminal is determined according to the error rate, and the electric quantity prompt aiming at the main control terminal is sent out, so that when the main control terminal is in a low electric quantity state, the prompt that the electric quantity of the controlled terminal is low aiming at the main control terminal is realized, and the user experience is enhanced.

When a user executes key operation on the infrared remote controller, the infrared remote controller sends out a control signal corresponding to each key. When detecting a control signal sent by an infrared remote controller, the television equipment starts to receive a target control signal (a plurality of continuous control signals which can be contained), continuously decodes the received target control signal to obtain target decoding information, counts the number of effective decoding information in the target decoding information and reports a key instruction corresponding to the effective decoding information to a corresponding data processing center; after decoding is finished, judging whether the receiving of the target control signal is finished, and calculating the error rate of the received target control signal when the receiving of the target control signal is confirmed to be finished; comparing the calculated error rate with a preset error rate threshold, and when the error rate is larger than the preset error rate threshold, determining that the electric quantity of the main control terminal is in a low electric quantity state, and generating low electric quantity prompt information to prompt the user for low electric quantity.
