Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. The embodiments based on the present invention should fall into the protection scope of the present invention.

First, an application scenario of the present invention is described, and the present invention may be applied to a mobile power supply rental device, where the mobile power supply rental device includes a charging module and a mobile power supply, and the charging module is configured to charge the mobile power supply, so that a user may use the mobile power supply to charge the mobile device. The present invention will be described in detail with reference to specific examples.

Fig. 1 is a schematic flow chart of a signal identification method according to an embodiment of the present invention, as shown in fig. 1, the method is applied to a charging module, and the method includes the following steps:

S101, acquiring a current request message.

in the embodiment of the present invention, the charging module may set corresponding preset periods for different request messages, so that the charging module respectively obtains the corresponding request messages according to the preset periods, where the request messages include: the mobile power source may be configured to acquire the first request message according to the first period, acquire the second request message according to the second period, and acquire the third request message according to the third period, where the above example is merely illustrative. Of course, the present invention may also receive a current request message sent by the terminal device bound to the charging module, for example, a control page of the terminal device includes trigger identifiers of different request messages, so that the charging module may obtain the request message corresponding to the target trigger identifier when the terminal device receives a trigger operation of a user on the target trigger identifier.

s102, determining a request optical signal corresponding to the current request message according to a preset request optical signal generation strategy.

In the embodiment of the present invention, the request light signal may be an infrared light signal or an ultraviolet light signal, and the request light signal may be determined in the following two ways:

The first method is as follows: when the request optical signal generation policy includes the transmission mode correspondence, the transmission mode correspondence includes a correspondence between a binary character and a signal transmission mode, and first, a binary character string corresponding to the current request message may be acquired. The corresponding relation of the character strings between the request message and the binary character string can be pre-established, so that the binary character string corresponding to the current request message can be obtained according to the corresponding relation of the character strings.

Illustratively, if the request message includes: a first request message requesting the mobile power supply to transmit identification information of the mobile power supply, a second request message requesting the mobile power supply to transmit remaining power of the mobile power supply, and a third request message requesting the mobile power supply to transmit a current temperature of the mobile power supply, etc., the binary string corresponding to the first request message may be set to "00", the binary string corresponding to the second request message may be set to "01", and the binary string corresponding to the third request message may be set to "10". It should be noted that the present invention can also use octal string, decimal string, hexadecimal string, etc. to represent the current request message.

And then, determining a signal transmission mode corresponding to each binary character included in the binary character string according to the transmission mode corresponding relation. Specifically, the signal emission mode is that the optical signal is continuously emitted within a first preset time period and is stopped to be emitted within a second preset time period, the first preset time period and the second preset time period are not zero, and the ending time of the first time period is the same as the starting time of the second time period; and the first preset time lengths corresponding to different binary characters are different, and/or the second preset time lengths corresponding to different binary characters are different.

illustratively, if the request message is represented by a binary character string according to the present invention, the binary character includes "0" and "1", and in order to distinguish between the binary character "0" and the binary character "1", a first preset duration corresponding to the binary character "1" is a duration, a second preset duration corresponding to the binary character "1" is a duration B, a first preset duration corresponding to the binary character "0" is a duration C, and a second preset duration corresponding to the binary character "0" is a duration D, where B ≠ D, and/or a ≠ C, such that the binary character "1" is transmitted in a manner that: the optical signal is continuously transmitted in the A time period and is stopped transmitting in the B time period, and the signal transmission mode of the binary character '0' is as follows: the optical signal is continuously emitted during the C duration and the emission is terminated during the D duration. Therefore, based on the signal transmission modes including various binary characters in the transmission mode corresponding relationship, the signal transmission mode corresponding to each binary character included in the binary character string can be quickly acquired from the transmission mode corresponding relationship.

Finally, the request light signal is determined based on the signal transmission mode of each binary character included in the binary character string. The request optical signal can be generated by transmitting each binary character included in the binary character string according to a corresponding signal transmission mode according to the character sequence of the binary character included in the binary character string.

For example, if the current request message is a first request message requesting the mobile power supply to send the identification information of the mobile power supply, and the binary string corresponding to the first request message is "00", the requested optical signal corresponding to the current request message includes: continuously emitting the optical signal in the C time length and stopping emitting in the D time length, and then continuously emitting the optical signal in the C time length and stopping emitting in the D time length; if the current request message is a second request message requesting the mobile power supply to send the remaining power of the mobile power supply, and the binary string corresponding to the second request message is "01", the light-requesting signal corresponding to the current request message includes: continuously emitting the optical signal in the time length C and stopping emitting in the time length D, and then continuously emitting the optical signal in the time length A and stopping emitting in the time length B; if the current request message is a third request message requesting the mobile power supply to send the current temperature of the mobile power supply, and the binary string corresponding to the third request message is "10", the light-requesting signal corresponding to the current request message includes: the optical signal is continuously emitted in the A duration and the emission is terminated in the B duration, followed by the optical signal being continuously emitted in the C duration and the emission being terminated in the D duration.

it should be noted that, in order to accurately identify the introduction and termination of the optical signal, the transmission method correspondence relationship in the present invention further includes: the corresponding relation between the optical signal leading-in mark and the signal emission mode and the corresponding relation between the optical signal termination mark and the signal emission mode. For example, the signal transmission mode corresponding to the optical signal import identifier may be set as follows: the optical signal is continuously transmitted within a third preset time, and the signal transmission mode corresponding to the optical signal termination identifier is set as follows: the optical signal is continuously transmitted within a fourth preset time period, and both the third preset time period and the fourth preset time period are not zero. For example, continuing with the above-mentioned "the current request message is the second request message requesting the mobile power supply to transmit the remaining power of the mobile power supply, and the binary string corresponding to the second request message is '01'," as an example, the optical signal corresponding to the current request message includes: the optical signal is continuously emitted in a third preset time period, then the optical signal is continuously emitted in a C time period and the emission is stopped in a D time period, then the optical signal is continuously emitted in an A time period and the emission is stopped in a B time period, and then the optical signal is continuously emitted in a fourth preset time period.

The second method comprises the following steps: in the case where the request optical signal generation strategy includes a number correspondence, the number correspondence includes a correspondence between the request message and the number of high-level pulses; firstly, the number of the target high-level pulses corresponding to the current request message is determined according to the number corresponding relation. Wherein, if the request message includes: requesting the mobile power supply to send a first request message of identification information of the mobile power supply, and setting the number of high-level pulses corresponding to the first request message as m; if the request message includes a second request message requesting the mobile power supply to send the remaining power of the mobile power supply, the number of high-level pulses corresponding to the second request message may be set to n; if the request message includes a third request message requesting the mobile power supply to transmit the current temperature of the mobile power supply, the number of high level pulses corresponding to the third request message may be set to p, and so on. Thus, in the case where it is determined that the current request message is the first request message, the target high level pulse number is m; the target high level pulse number is n if the current request message is determined to be the second request message, and p if the current request message is determined to be the third request message.

The requested optical signal is then determined based on the target number of high level pulses. Wherein, because the transmitted optical signal has the characteristic of high-low level pulse, the high level pulse with the target high level pulse number can be set in the transmitted optical signal to obtain the request optical signal.

S103, sending the request optical signal to a mobile power supply so that the mobile power supply can identify the current request message corresponding to the request optical signal according to a pre-stored request optical signal generation strategy.

in this step, the request optical signal may be sent by a transmitter in the charging module, and specifically, the sending step of the request optical signal may be performed by using a diode in the transmitter.

In addition, the invention can also carry out filtering processing on the request optical signal and send the filtered request optical signal to the mobile power supply.

In the embodiment of the present invention, the request light signal generation policy may be pre-stored in the charging module and the mobile power supply, respectively. Wherein, under the condition that the request optical signal generation strategy comprises the corresponding relation of the emission modes, the mobile power supply times the continuously emitted optical signals to obtain a first preset time length, and the time for terminating the emission of the optical signal after the first preset time length is timed to obtain a second preset time length, and so on, the first and second preset durations may be obtained for each binary character comprised in the binary string, such that, the binary character corresponding to the first preset time length and the second preset time length can be obtained through the corresponding relation of the transmitting modes, and character-combining the binary character to obtain a binary character string corresponding to the request light signal, therefore, the current request message corresponding to the binary character string is obtained based on the corresponding relation of the character string, wherein the corresponding relation of the character string is the corresponding relation between the request message and the binary character string which is established in advance; in the case that the request optical signal generation policy includes the number correspondence, the mobile power supply may acquire a target high-level pulse number of the high-level pulses included in the request optical signal, and thus may acquire the current request message corresponding to the target high-level pulse number according to the number correspondence.

since the invention uses the continuous emission and the continuous termination of the emission of the optical signal as the basic unit of the signal identification, so that the optical signal in the invention has the high-low level pulse characteristic and is distinguished from the external light, the mobile power supply in the invention detects whether the high-low level pulse characteristic exists in the optical signal under the condition of receiving the optical signal, and determines the optical signal as the request optical signal under the condition that the high-low level pulse characteristic exists in the optical signal, thus the external light can be accurately distinguished from the optical signal in the invention.

In addition, in an optional embodiment of the present invention, the charging module further needs to receive a response optical signal sent by the mobile power supply; the response optical signal is an optical signal of a response message corresponding to the current request message; then, according to a response optical signal generation strategy stored in advance, response messages corresponding to the response optical signals are identified, wherein the response optical signal generation strategy can be any one of the following strategies: a transmission mode corresponding relation, which comprises a corresponding relation between the binary character and the signal transmission mode; and a number correspondence relationship including a correspondence relationship between the request message and the number of high level pulses. In addition, because there is interference light in the environment that charging module and portable power source are located, in order to prevent the wrong receipt of interference light, can filter the response light signal to filter interference light, thereby obtain the response light signal who filters interference light, at this moment, according to response light signal generation strategy, discern the response message that the response light signal after the filtering process corresponds.

by adopting the method, the charging module can firstly acquire the current request message; then, according to a preset request optical signal generation strategy, determining a request optical signal corresponding to the current request message; and then sending the request optical signal to the mobile power supply so that the mobile power supply can generate a strategy according to the pre-stored request optical signal and identify the current request message corresponding to the request optical signal. Therefore, the charging module and the mobile power supply respectively pre-store the request optical signal generation strategy, so that the optical signals can be accurately identified based on the request optical signal generation strategy, optical signal communication between low-cost small-sized equipment is realized, and the problem that the optical signal communication between the low-cost small-sized equipment cannot be carried out due to the high cost of the infrared receiving head is solved.

fig. 2 shows a signal identification method according to an embodiment of the present invention, where the method is applied to a mobile power source, and as shown in fig. 2, the method includes the following steps:

S201, receiving a request light signal sent by the charging module.

In the embodiment of the present invention, the request optical signal may be received by a receiver in the mobile power supply, and in particular, the receiving step of the request optical signal may be performed by using a diode provided in the receiver.

s202, according to a pre-stored request optical signal generation strategy, identifying a current request message corresponding to the request optical signal.

in the embodiment of the present invention, the request light signal generation policy may be pre-stored in the charging module and the mobile power supply, respectively. Wherein, under the condition that the request optical signal generation strategy comprises the corresponding relation of the emission modes, the mobile power supply times the continuously emitted optical signals to obtain a first preset time length, and the time for terminating the emission of the optical signal after the first preset time length is timed to obtain a second preset time length, and so on, the first and second preset durations may be obtained for each binary character comprised in the binary string, such that, the binary character corresponding to the first preset time length and the second preset time length can be obtained through the corresponding relation of the transmitting modes, and character-combining the binary character to obtain a binary character string corresponding to the request light signal, therefore, the current request message corresponding to the binary character string is obtained based on the corresponding relation of the character string, wherein the corresponding relation of the character string is the corresponding relation between the request message and the binary character string which is established in advance.

It should be noted that, in order to accurately identify the introduction and termination of the optical signal, the transmission method correspondence relationship in the present invention further includes: the corresponding relation between the optical signal leading-in mark and the signal emission mode and the corresponding relation between the optical signal termination mark and the signal emission mode. For example, the signal transmission mode corresponding to the optical signal import identifier may be set as follows: the optical signal is continuously transmitted within a third preset time, and the signal transmission mode corresponding to the optical signal termination identifier is set as follows: the optical signal is continuously transmitted within a fourth preset time period, and both the third preset time period and the fourth preset time period are not zero. At this time, the mobile power supply may first identify an optical signal continuously transmitted within a third preset duration, then time the continuously transmitted optical signal after the third duration to obtain a first preset duration, and time the time that the optical signal is terminated to be transmitted after the first preset duration to obtain a second preset duration, thereby determining a first binary character according to the first preset duration and the second preset duration, and so on, identifying all the binary characters, and finally, after identifying the optical signal continuously transmitted within a fourth preset duration, determining that the reception of the request optical signal is completed. Therefore, the binary character string can be accurately identified through the optical signal lead-in identification and the signal termination identification, and the current request message corresponding to the binary character string is obtained based on the character string corresponding relation.

in the case that the request optical signal generation policy includes the number correspondence, the mobile power supply may acquire a target high-level pulse number of the high-level pulses included in the request optical signal, and thus may acquire the current request message corresponding to the target high-level pulse number according to the number correspondence.

in addition, because there is interference light in the environment that charging module and portable power source are located, in order to prevent the wrong receipt of interference light, can carry out filtering processing to the request light signal that receives to filter interference light, thereby obtain the request light signal of filtering interference light.

in summary, the mobile power supply in the embodiment of the present invention may conveniently identify the optical signal based on the pre-stored request optical signal generation policy, and does not need to use a high-cost infrared signal receiving circuit in the mobile power supply, thereby reducing the generation cost of the device.

s203, acquiring a response message corresponding to the current request message, and determining a response optical signal corresponding to the response message according to a preset response optical signal generation strategy.

In this embodiment of the present invention, if the current request message includes a first request message requesting the mobile power supply to send identification information of the mobile power supply, the response message may include the identification information of the mobile power supply; if the current request message includes a second request message requesting the mobile power supply to send the remaining power amount of the mobile power supply, the response message may include the remaining power amount of the mobile power supply; if the current request message includes a third request message requesting the mobile power supply to transmit the current temperature of the mobile power supply, the response message may include the current temperature of the mobile power supply, and so on.

Wherein, the response optical signal generation strategy can be any one of the following: the corresponding relation of the transmission modes comprises the corresponding relation between binary characters and signal transmission modes; and a number correspondence, the number correspondence including a correspondence between the request message and the number of high level pulses. Since the information indicated by the number of high-level pulses is limited and the information included in the response signal is large, the response optical signal generation strategy is preferably: and transmitting mode corresponding relation. For example, if the response message includes the current temperature of the mobile power supply, the current temperature may not be represented due to a limited number of high level pulses, or the current temperature may be more accurately represented using a binary character because it takes a long time to represent the temperature in this manner and the processing efficiency is low.

S204, sending the response optical signal to the charging module so that the charging module generates a strategy according to the response optical signal stored in advance and identifies a response message corresponding to the response optical signal.

in the embodiment of the present invention, the response optical signal generation policy may be pre-stored in the charging module and the mobile power supply, respectively. Wherein, under the condition that the strategy for generating the response optical signal includes the corresponding relationship of the transmission mode, the charging module clocks the continuously transmitted optical signal to obtain a first preset time length, clocks the time for terminating the transmission of the optical signal after the first preset time length to obtain a second preset time length, and so on, the first preset time length and the second preset time length of each binary character included in the binary character string can be obtained, so that the binary characters corresponding to the first preset time length and the second preset time length can be obtained through the corresponding relationship of the transmission mode, and the binary character string corresponding to the response optical signal can be obtained by performing character combination on the binary characters, so as to obtain the response message based on the binary character string, for example, if the current request message is a request message for requesting the mobile power supply to send the remaining electric quantity of the mobile power supply, in case that it is detected that the binary string corresponding to the response light signal is "11011", it may be determined that the response message includes that the remaining power of the mobile power supply is 27%; in a case that the response optical signal generation policy includes a number correspondence relationship, the charging module may obtain a current high-level pulse number of high-level pulses included in the response optical signal, so as to obtain a response message according to the current high-level pulse number, for example, if the current request message is a request message requesting the mobile power supply to send a current temperature of the mobile power supply, when it is detected that 25 high-level pulses are included in the response optical signal, the current temperature of the mobile power supply may be determined to be 25 degrees celsius, which is merely an example, and the present invention is not limited thereto.

In addition, in order to avoid interference light, the mobile power supply can also filter the response light signal and send the response light signal after filtering to the charging module; and/or after receiving the response optical signal, the charging module can filter the response optical signal, and identify a response message corresponding to the response optical signal after filtering processing according to a pre-stored response optical signal generation strategy.

optionally, in order to further prevent the charging module from receiving the interference light by mistake, the step may send the response optical signal and the preset verification code to the charging module, so that the charging module acquires the verification code to be verified according to the response message when recognizing the response message corresponding to the response optical signal, and performs signal verification through the verification code to be verified and the preset verification code. And determining that no interference signal exists in the response optical signal under the condition that the verification code to be verified is the same as the preset verification code, and determining that the interference signal exists in the response optical signal under the condition that the verification code to be verified is different from the preset verification code. Therefore, whether interference light exists in the response optical signal or not can be judged in a data verification mode, and the charging module does not need to perform signal identification on the response optical signal under the condition that the interference light exists in the response optical signal.

by adopting the method, the mobile power supply firstly receives a request optical signal sent by the charging module, then generates a strategy according to the pre-stored request optical signal, identifies a current request message corresponding to the request optical signal, then acquires a response message corresponding to the current request message, and determines a response optical signal corresponding to the response message according to a preset response optical signal generation strategy; and finally, sending the response optical signal to the charging module so that the charging module generates a strategy according to the pre-stored response optical signal and identifies a response message corresponding to the response optical signal. Therefore, the charging module and the mobile power supply respectively pre-store the request optical signal generation strategy, so that the optical signals can be accurately identified based on the request optical signal generation strategy, optical signal communication between low-cost small-sized equipment is realized, and the problem that the optical signal communication between the low-cost small-sized equipment cannot be carried out due to the high cost of the infrared receiving head is solved.

Fig. 3 is a schematic flow chart of a signal identification method according to an embodiment of the present invention, as shown in fig. 3, the method includes the following steps:

s301, the charging module acquires the current request message.

for a specific process, refer to step S101, which is not described again.

and S302, the charging module determines a request optical signal corresponding to the current request message according to a preset request optical signal generation strategy.

The specific process may refer to step S102, and is not described in detail.

And S303, the charging module sends the request light signal to the mobile power supply.

In this step, a transmitter provided with a diode may be included in the charging module, so as to implement the transmission of the request optical signal through the diode in the transmitter, and a receiver provided with a diode may be included in the mobile power supply, so as to implement the reception of the request optical signal through the diode in the receiver.

in addition, in order to avoid interference light, the charging module may filter the request light signal and send the filtered request light signal to the portable power source.

and S304, the mobile power supply performs filtering processing on the request light signal.

In consideration of the fact that the mobile power supply includes a receiver, a transmitter and a processor, an optical filter for filtering the request light signal may be provided at the front end of the receiver of the mobile power supply.

Since the information indicated by the number of high-level pulses is limited and the information included in the response signal is large, the response optical signal generation strategy is preferably: and transmitting mode corresponding relation. For example, if the response message includes the current temperature of the mobile power supply, the current temperature may not be represented due to the limited number of high level pulses, and thus, the current temperature may be more accurately represented using a binary character.

In addition, in order to avoid interfering light, the portable power source can filter the response light signal and send the response light signal after the filtering process to the charging module.

in order to enable the charging module to distinguish the response optical signal from the preset verification code, in a possible implementation manner, the response optical signal may be first sent, and in a case that the sending of the response optical signal is completed, the optical signal termination identifier is then sent, the preset verification code is then continuously sent, and in a case that the sending of the preset verification code is completed, the signal completion identifier is finally sent, for example, the signal completion identifier is an optical signal that is continuously sent for a specified duration.

S308, the charging module carries out filtering processing on the response optical signal.

Similarly, because there is interference light in the environment that charging module and portable power source are located, in order to prevent the wrong receipt of interference light, can filter the response light signal that receives to filter interference light, thereby obtain the response light signal who filters interference light. In consideration of the fact that the charging module includes a receiver, a transmitter and a processor, an optical filter may be disposed at a front end of the receiver of the charging module, and the optical filter is used for filtering the response light signal.

s309, the charging module identifies response messages corresponding to the filtered response optical signals according to the response optical signal generation strategy, acquires verification codes to be verified according to the response messages, and performs signal verification through the verification codes to be verified and preset verification codes.

in the embodiment of the present invention, the response optical signal generation policy may be pre-stored in the charging module and the mobile power supply, respectively. In this way, the charging module identifies the response message corresponding to the response optical signal after the filtering processing according to the pre-stored response optical signal generation strategy. The specific process may refer to step S204.

And determining that no interference signal exists in the response optical signal under the condition that the verification code to be verified is the same as the preset verification code, and determining that the interference signal exists in the response optical signal under the condition that the verification code to be verified is different from the preset verification code. Therefore, whether interference light exists in the response optical signal or not can be judged in a data verification mode, and the charging module does not need to perform signal identification on the response optical signal under the condition that the interference light exists in the response optical signal.
