[ detailed description ] of the invention
For a better understanding of the technical solution of the present invention, the following detailed description of the embodiments of the present invention refers to the accompanying drawings.
It should be understood that the described embodiments are merely some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a flowchart of an embodiment of a signaling method according to an embodiment of the present invention. Referring to fig. 1, the method comprises the steps of:
step 101, determining the total pulse number of the current pulse signals to be transmitted according to the data to be transmitted;
102, if the total pulse number is smaller than or equal to a pulse number threshold, transmitting the current pulse signal to be transmitted to a receiving end;
step 103, if the total pulse number is greater than a pulse number threshold, dividing the current pulse signal to be sent into a plurality of sub-pulse signals and sequentially sending the sub-pulse signals to a receiving end; the number of pulses contained in each sub-pulse signal is smaller than the threshold value of the number of pulses.
Because there is no delay in the data transmission mode with electrical connection or in an ideal state, as long as the interval time of the data bits sent by the sending end is reasonably fixed, the receiving end can almost read the high and low levels of the data bits in the middle section of the fixed time (because the middle section is more reliable to read). At this time, after the receiving end receives the first trigger, all the data read subsequently are correct.
In the wireless transmission mode, when the transmitting end transmits the pulse signal, although the pulse signal is transmitted at fixed intervals, the interval time of the pulse signal received at the receiving end changes after the pulse signal passes through the wireless coil, and the pulse signal is transmitted on the same coil with low-frequency data transmission and high-frequency power supply energy transmission, so that the signal can be interfered, the time interval of the pulse signal received at the receiving end is different, and the high-low level of the pulse signal can not be correctly read in the fixed time.
Therefore, the signal sending method of the embodiment is mainly applied to a scenario that pulse signals are transmitted between a sending end and a receiving end in a wireless transmission mode and signal interference exists, and the method of the embodiment is applied to the sending end.
Specifically, as described in step 101, the total pulse number of the pulse signal to be transmitted is determined according to the data to be transmitted.
The data to be sent by the sending end can be determined according to different application scenes, for example, if the application scene is an electric kettle, the kettle body (serving as the sending end) of the electric kettle transmits water temperature data in the electric kettle to the base (serving as the receiving end), and the data to be sent is temperature data.
In one implementation, the total pulse number of the pulse signal to be sent is determined according to the value of the data to be sent. For example, if the data to be sent is 45 degrees celsius (i.e., the value of the data to be sent is 45 degrees celsius), the total number of pulses of the current pulse signal to be sent is 45. That is, the total number of pulses of the pulse signal to be transmitted currently is equal to the value of the data to be transmitted currently.
However, according to the above implementation, there is a problem that if the data to be transmitted is 0 degrees celsius (i.e., the value of the data to be transmitted is 0), the total number of pulses of the current pulse signal to be transmitted is 0, i.e., no pulse signal can be transmitted.
Accordingly, the inventors contemplate that in another implementation, the step comprises:
step 1011, setting the lowest pulse number.
Step 1012, determining the total pulse number of the current pulse signal to be sent according to the sum of the data to be sent and the minimum pulse number.
In step 1011, the minimum pulse number is a natural number greater than 0, and the minimum pulse number is not set to a natural number having a too large value, and the minimum pulse number may be set to a natural number between 5 and 10. In step 1012, when determining the total number of pulses of the current pulse signal to be transmitted, the total number of pulses is determined according to the sum of the minimum number of pulses and the data to be transmitted. For example, if the minimum pulse number is 5, when the value of the data to be transmitted is 0, the total pulse number of the current pulse signal to be transmitted is 5. And when the value of the data to be transmitted is 45, the total pulse number of the pulse signal to be transmitted is 50.
In practical applications, if the value of the data to be sent is large (for example, 500, 1000, etc.), the total number of pulses of the pulse signal to be sent is large according to the above manner of step 101, and in this case, if the pulse signal to be sent including all the total number of pulses is sent to the receiving end at one time, it is not easy for the receiving end to accurately receive the data to be sent. Therefore, in this embodiment, a pulse number threshold is set, where the pulse number threshold is the maximum pulse number included in a pulse signal to be transmitted.
And step 102, if the total pulse number is less than or equal to the pulse number threshold, transmitting the current pulse signal to be transmitted to a receiving end.
Step 103, if the total pulse number is greater than a pulse number threshold, dividing the current pulse signal to be transmitted into a plurality of sub-pulse signals and sequentially transmitting the sub-pulse signals to a receiving end; the number of pulses contained in each sub-pulse signal is smaller than the threshold value of the number of pulses.
Specifically, the method comprises the following steps:
step 1031, dividing the pulse signal to be sent into a plurality of sub-pulse signals according to the total pulse number of the pulse signal to be sent, so that the pulse number contained in each sub-pulse signal is smaller than the pulse number threshold;
step 1032, transmitting the sub-pulse signals one by one until all the sub-pulse signals are transmitted to the receiving end, and a first transmission time interval is reserved between two adjacent sub-pulse signals.
After determining the total pulse number of the current pulse signal to be sent according to the step 101, comparing the total pulse number with the pulse number threshold, and if the total pulse number is smaller than or equal to the pulse number threshold, directly sending the current pulse signal to be sent to a receiving end.
Otherwise, if the total pulse number is greater than the pulse number threshold, the current pulse signal to be sent is further divided into a plurality of sub-pulse signals according to the total pulse number, and in this embodiment, the number of pulses included in each sub-pulse signal is not limited, but the condition that the number of pulses included in each sub-pulse signal is less than the pulse number threshold needs to be satisfied.
In one implementation, for example, the total number of pulses is divided by the threshold number of pulses, and if the total number of pulses is divided, the quotient obtained is determined as the number of sub-pulse signals, and the number of pulses included in each sub-pulse signal is the threshold number of pulses, so that the number of sub-pulse signals can be reduced as much as possible. For example, if the total number of pulses is 80, the threshold number of pulses is 10, and the quotient of the total number of pulses divided by the threshold number of pulses is 8, the current pulse signal to be transmitted is divided into 8 sub-pulse signals, and the number of pulses included in each sub-pulse signal is 10.
For another example, the total pulse number is divided by the pulse number threshold, and if there is a remainder, the quotient obtained is added with a number determined as the number of sub-pulse signals, and the remainder is the number of pulses included in the last sub-pulse signal. For example, if the total number of pulses is 85, the threshold number of pulses is 10, the quotient of the total number of pulses divided by the threshold number of pulses is 8, and the remainder is 5, the number of sub-pulse signals is determined to be 9, wherein each sub-pulse signal in the first 8 sub-pulse signals contains 10 pulses, and the last sub-pulse signal contains 5 pulses.
In other implementations, the number of pulses included in each sub-pulse signal may be less than the threshold number of pulses, and the number of pulses included in each sub-pulse signal may be different. In this way, the number of sub-pulse signals may be increased, and the number of pulses included in each sub-pulse signal may be reduced, compared to the previous implementation.
In step 1032, in order to ensure that the receiving end can accurately receive the data to be transmitted sent by the transmitting end, in the case of dividing the pulse signal to be transmitted into a plurality of sub-pulse signals, the sub-pulse signals need to be sent to the receiving end one by one until all the sub-pulse signals are sent to the receiving end. Unlike the prior art, the data to be transmitted is determined at the receiving end according to the total pulse number of the received pulse signals to be transmitted, rather than determining the corresponding data bit according to the high and low levels of the pulse signals transmitted at the corresponding time of each transmitting end. Therefore, in this step, the transmission sequence is not limited between the sub-pulse signals.
In order to enable the receiving end to determine whether the sub-pulse signal to be transmitted still exists after the currently received sub-pulse signal, a first transmission time interval exists between two adjacent sub-pulse signals transmitted by the transmitting end, and a specific time interval can be pre-agreed between the transmitting end and the receiving end. Therefore, after receiving a sub-pulse signal, if the receiving end receives the sub-pulse signal again in the first sending time interval, the receiving end can determine that the sub-pulse signal still belongs to the current pulse signal to be sent.
Further, in this embodiment, after the current pulse signal to be sent is sent to the receiving end, if the next pulse signal to be sent is to be sent, after the second sending time interval elapses, a trigger pulse signal is sent to the receiving end first.
Specifically, in order for the receiving end to determine whether the currently received sub-pulse signal is the last sub-pulse signal in the current pulse signal to be transmitted, a second transmission time interval will be also pre-agreed between the transmitting end and the receiving end. Thus, after the receiving end receives the sub-pulse signal, if a pulse signal (actually, a trigger pulse signal sent by the sending end) is received after the second sending time interval, the receiving end can determine that the sub-pulse signal received before is the last sub-pulse signal in the pulse signal to be sent currently, that is, the pulse signal to be sent currently is sent completely.
In practical applications, the second transmission time interval may be set longer than the first transmission time interval, for example, the first transmission time interval is 3 ms and the second transmission time interval is 10 ms.
It should be noted that, when the transmitting end directly transmits the current pulse signal to be transmitted to the receiving end, if the next pulse signal to be transmitted is to be transmitted, it is also necessary to transmit the trigger pulse signal to the receiving end after the second transmission time interval.
Fig. 2 is a flowchart of an embodiment of a signal receiving method according to an embodiment of the present invention. Referring to fig. 2, the method includes the steps of:
step 201, after receiving the trigger pulse signal, receiving the pulse signal; the pulse signal is sent to the receiving end by the sending end according to the signal sending method;
step 202, judging whether the next pulse signal is received after the pulse signal is received currently and the first transmission time interval passes;
step 203, if yes, continuing to receive the next pulse signal until the next pulse signal is received currently and is not received within the second transmission time interval, and determining that the data to be transmitted is received;
and 204, determining the data to be transmitted based on the pulse numbers contained in all the received pulse signals.
The signal receiving method of the present embodiment is also mainly applied to a scenario in which a pulse signal is transmitted between a transmitting end and a receiving end in a wireless transmission manner and signal interference exists, and the present embodiment is applied to the receiving end, where the receiving end receives a pulse signal to be transmitted, which is transmitted by the transmitting end according to the signal transmitting method provided in the embodiment of fig. 1.
After receiving the trigger pulse signal, the pulse signal is received, as described in step 201.
Specifically, the receiving end starts to count the received pulse signals after receiving the trigger pulse signals sent by the sending end. For example, during initial signal receiving and transmitting, the transmitting end transmits a trigger pulse signal to the receiving end, and the receiving end starts to receive subsequent pulse signals after receiving the trigger pulse signal. For another example, when the transmitting end transmits a current pulse signal to be transmitted to the receiving end, after a second transmission time interval, a trigger pulse signal is transmitted to the receiving end before the next pulse signal to be transmitted is transmitted. That is, in the process of receiving and transmitting signals, when the receiving end receives the last pulse signal to be transmitted and passes the second transmission time interval, the pulse signal received again is regarded as the trigger pulse signal (i.e. triggering the receiving of the next pulse signal to be transmitted).
In step 202, it is determined whether the next pulse signal is received after the first transmission time interval has elapsed while the pulse signal is currently received.
Specifically, since the receiving end does not know in advance whether the currently received pulse signal is a complete pulse signal to be transmitted or a sub pulse signal in the pulse signal to be transmitted. Therefore, when receiving a pulse signal, the receiving end will determine whether the next pulse signal is received again after the first transmission time interval.
As described in the embodiment of fig. 1 above, the first transmission time interval is a transmission time interval of two adjacent sub-pulse signals. Therefore, as described in step 203, if the receiving end receives the next pulse signal after the first transmission time interval, it is determined that the currently received pulse signal is a sub pulse signal in the pulse signal to be transmitted, and then the receiving end continues to receive the next pulse signal, and so on, until the receiving end receives the pulse signal currently and does not receive the next pulse signal after the second transmission time interval, it is determined that the receiving of the data to be transmitted is completed. That is, when the receiving end does not receive the next pulse signal after receiving a certain pulse signal in the second transmission time interval, the certain pulse signal is the last sub-pulse signal in the currently received pulse signal to be transmitted, so as to determine that the receiving end finishes receiving the currently transmitted pulse signal sent by the transmitting end (i.e. finishes receiving the data to be transmitted).
The data to be transmitted is determined based on the number of pulses contained in all the received pulse signals, as described in step 204.
Specifically, after the receiving end determines that the current pulse signal to be sent by the sending end is received, the number of pulses contained in all pulse signals received after the trigger pulse signal is received is counted, so that the data to be sent is determined according to the number of pulses contained in all pulse signals (namely, the total number of pulses of the current pulse signal to be sent).
Corresponding to the embodiment shown in fig. 1, for example, if the transmitting end takes the total number of pulses of the current pulse signal to be transmitted as the value of the current data to be transmitted. At the receiving end, the data to be sent is directly determined according to the pulse numbers contained in all the pulse signals, namely, the numerical value of the pulse numbers is equal to the numerical value of the data to be sent. For another example, if the transmitting end and the receiving end pre-agree with the minimum pulse number, the total pulse number of the current pulse signal to be transmitted is the sum of the data to be transmitted and the minimum pulse number. And at the receiving end, determining the data to be received according to the difference between the number of pulses contained in all the received pulse signals and the minimum number of pulses.
Further, the embodiment further includes the following steps:
if the determination result in step 202 is no (i.e. if the next pulse signal is not received in the first transmission time interval and the pulse signal is currently received), it is determined whether the next pulse signal is not received in the second transmission time interval. If yes, the data to be received is determined based on the number of pulses contained in the pulse signal received currently.
Specifically, after receiving a pulse signal, the receiving end does not receive a next pulse signal in the first sending time interval, and does not receive a next pulse signal in the second sending time interval, then determining that the pulse signal currently received is a complete current pulse signal to be sent by the sending end, and then determining the data to be received based on the number of pulses contained in the pulse signal currently received.
Fig. 3A is a schematic diagram of an embodiment of transmitting and receiving a pulse signal according to an embodiment of the present invention.
The embodiment is a schematic diagram that a transmitting end divides a pulse signal to be transmitted into a plurality of sub-pulse signals and sequentially transmits the sub-pulse signals to a receiving end.
Referring to fig. 3A, one sub-pulse signal of the pulse signals to be transmitted from the transmitting end is a pulse signal of a fixed pulse width, for example, a pulse width of 0.5 ms. In the process of receiving the pulse signal, the pulse width of the received pulse signal may not be completely consistent due to factors such as signal interference. However, in this embodiment, the receiving end only counts the number of pulses in the received pulse signal, and does not calculate when the pulses are received.
The first pulse signal sent by the sending end is a trigger pulse signal, after the receiving end receives the trigger pulse signal, the receiving end starts to receive subsequent pulse signals, as shown in fig. 3A, the sub-pulse signals sent subsequently by the sending end include 7 pulses, and correspondingly, the receiving end receives the 7 pulses sequentially at different time points (i.e. the sending time of the corresponding pulse of the pulse signal of the sending end does not completely correspond to the sending time of the corresponding pulse of the pulse signal of the sending end), and then counts the number of pulses in the sub-pulse signals after the sub-pulse signals are received, i.e. counts +1 of the number of pulses when each pulse is received. Then, the transmitting end continues to transmit the next sub-pulse signal to the receiving end after the first transmitting time interval, and correspondingly, the receiving end receives the next pulse signal after the first transmitting time interval. And by analogy, the transmitting end finishes transmitting the whole pulse signal to be transmitted, the receiving end correspondingly finishes receiving the pulse signal to be transmitted, and the data to be transmitted is determined according to the pulse numbers contained in all the sub-pulse signals.
Fig. 3B is a schematic diagram of another embodiment of transmitting and receiving a pulse signal according to an embodiment of the present invention.
The embodiment is a schematic diagram that a transmitting end directly transmits a pulse signal to be transmitted to a receiving end.
Referring to fig. 3B, the pulse signal to be transmitted by the transmitting end is also a pulse signal with a fixed pulse width, for example, a pulse width of 0.5 ms. In the process of receiving the pulse signal, the pulse width of the received pulse signal may not be completely consistent due to factors such as signal interference. However, in this embodiment, the receiving end only counts the number of pulses in the received pulse signal, and does not calculate when the pulses are received.
The first pulse signal sent by the sending end is a trigger pulse signal, after the receiving end receives the trigger pulse signal, the receiving end starts to receive subsequent pulse signals, as shown in fig. 3B, the pulse signal to be sent, which is sent by the sending end subsequently, includes 7 pulses, correspondingly, the receiving end sequentially receives the 7 pulses at different time points (i.e. the sending time of the corresponding pulse of the pulse signal of the sending end does not completely correspond to the sending time of the corresponding pulse of the pulse signal of the sending end), and further after the receiving end receives the pulse signal to be sent, the number of pulses in the pulse signal to be sent is counted, i.e. the count of the number of pulses is +1 after each pulse is received. And determining the data to be transmitted according to the number of all the pulses contained in the pulse signal to be transmitted.
