Example one
Fig. 1 is a flowchart of a communication method provided in an embodiment of the present invention, where the present embodiment is applicable to a case of single-wire serial port adaptive communication, and the method may be executed by a communication device in an embodiment of the present invention, where the device may be implemented in a software and/or hardware manner, and in a specific embodiment, the device may be integrated in a communication device, and the communication device may be a Microcontroller Unit (MCU). The following embodiments will be described by taking as an example that the apparatus is integrated in a communication device, as shown in fig. 1, the method specifically includes the following steps:
s110, determining initial delay time according to the baud rate of the communication equipment, and communicating with the testing equipment according to the initial delay time to obtain a communication result.
The communication device may be an MCU or other device with single-wire serial communication function. The delay time refers to the time the communication device is used to receive data during a communication. The initial delay time refers to a theoretical time for receiving data determined according to the baud rate of the communication device at the start of communication. The test equipment can be a computer or other equipment with the function of transmitting and receiving data. The present embodiment is only illustrated by taking the communication device and the testing device as an example, and is not limited. The communication result refers to a result of whether data transmission between the test device and the communication device is successful.
Specifically, the baud rate of the communication device may be calculated and determined according to the internal oscillation frequency of the communication device, and the delay time of the communication device may be calculated after the baud rate is determined. The delay time of a communication device is theoretically one-half of the baud rate. That is, if the Baud rate of the communication device is 9600Baud, the theoretically calculated delay time is 1/9600 sec, 104 μ sec. And adjusting the theoretical delay time obtained by calculation, and communicating with the test equipment by taking the adjusted delay time as the initial delay time. In this embodiment, the theoretical delay time may be adjusted by taking 0.5 to 0.6 times the theoretical delay time as the initial delay time.
Further, the test equipment sends data to the communication equipment based on the initial delay time, if the data received by the communication equipment is consistent with the data sent by the test equipment, the communication result is normal, and if the data received by the communication equipment is inconsistent with the data sent by the test equipment, the communication result is abnormal.
The example is given by taking the communication device as an MCU and the test device as a computer. The oscillation frequency of different MCUs is different, the internal oscillation frequency of the MCU is determined according to the known parameters of the MCU, and the baud rate has different calculation methods according to different working modes of serial ports of the MCU. In this embodiment, the working mode 0 of the serial port of the MCU is selected, so the baud rate is a fixed baud rate obtained by dividing the oscillation frequency by 12. If the Baud rate of the MCU is determined to be 9600Baud through calculation, the delay time obtained through theoretical calculation is 104 microseconds. Taking 0.5 times of the administrative delay time as the initial delay time, the initial delay time for the communication between the MCU and the computer is 52 microseconds. Based on the initial delay time of 52 microseconds, the computer sends data 0xaa to the MCU, and if the data received by the MCU is 0xaa, the communication between the MCU and the computer is normal.
It should be noted that, in the present embodiment, the initial delay time for communication is only 0.5 to 0.6 times the delay time theoretically calculated, and therefore, based on the initial delay time, the communication result between the MCU and the computer is necessarily a communication abnormality. That is, the communication result obtained in this step is a communication abnormality.
And S120, when the communication result shows that the communication is abnormal, adjusting the initial delay time until the communication is normal to obtain a first delay time.
Wherein, the communication abnormity refers to data transmission failure between the communication equipment and the test equipment. It will be appreciated that the data received by the communication device is not consistent with the data sent by the test device. The normal communication means that data transmission between the communication device and the test device is successful. It will be appreciated that the data received by the communication device is consistent with the data sent by the test device. The first delay time refers to the delay time when the communication result between the communication device and the test device is changed from abnormal to normal by continuously adjusting the initial delay time.
Specifically, based on the initial delay time obtained in step S110, the communication result between the communication device and the test device is a communication abnormality. For example, the theoretical delay time of the communication device is 104 microseconds, the test device sends data 0xaa to the communication device based on the initial delay time of 52 microseconds, and the communication result indicates that the communication is abnormal because the difference between the initial delay time and the theoretical delay time is large and the data received by the test device is not 0 xaa. And when the communication result is abnormal communication, adjusting the initial delay time to be close to the theoretical delay time, and when the communication result between the communication equipment and the test equipment indicates normal communication based on the adjusted delay time, recording the delay time adopted when the current communication is normal, and taking the delay time as the first delay time.
Optionally, when the adjusted initial delay time is close to the theoretical delay time, the unit delay time may be increased each time, or the initial delay time may be adjusted in stages, for example, when the difference between the initial delay time and the theoretical delay time is large, a large adjustment amount may be set, and when the difference between the initial delay time and the theoretical delay time is small, a small adjustment amount may be set. For example, based on the parameters of the communication device, the theoretical delay time of the communication device is 104 microseconds calculated according to the baud rate, based on the initial delay time of 52 microseconds, the test device sends data 0xaa to the communication device, because the difference between the initial delay time and the theoretical delay time is large, the data received by the communication device is not 0xaa, and the communication result between the communication device and the test device is communication abnormality at this time. When the communication result indicates that the communication is abnormal, the initial delay time may be increased by 1 microsecond, the initial delay time is adjusted to 53 microseconds, and based on the delay time of 53 microseconds, the test device sends data 0xaa to the communication device. And comparing whether the data received by the communication equipment is 0xaa, if not, continuing to increase the initial delay time to 54 microseconds, and sending the data 0xaa to the communication equipment by the test equipment based on the delay time of 54 microseconds. Comparing whether the data received by the communication device is 0xaa, if not, continuously increasing the initial delay time, theoretically, when the initial delay time is adjusted to be near the theoretical delay time, a situation that the communication is successful occurs, that is, the data received by the communication device is the same as the data of the test device, and is 0 xaa. For example, when the initial delay time is adjusted to 102 microseconds, the data received by the communication device is data 0xaa sent by the test device, and 102 microseconds is recorded as the first delay time.
S130, adjusting the first delay time until the communication is abnormal to obtain second delay time.
The second delay time refers to the delay time when the communication result between the communication equipment and the test equipment is changed from normal to abnormal by continuously adjusting the first delay time.
Specifically, based on the first delay time obtained in step S120, the communication result between the communication device and the test device is that the communication is normal. And when the communication result is normal communication, continuously adjusting the first delay time to be far away from the theoretical delay time, and when the communication result between the communication equipment and the test equipment is abnormal again based on the adjusted delay time, recording the delay time adopted by the communication equipment with abnormal communication last time, and taking the delay time as a second delay time.
Optionally, when the first delay time is adjusted to be away from the theoretical delay time, the unit delay time may be increased each time. For example, the first delay time obtained based on the above steps is 102 microseconds, the first delay time may be increased by a unit delay time of 1 microsecond, the first delay time is adjusted to 103 microseconds, and based on the delay time of 103 microseconds, the test device sends data 0xaa to the communication device. And comparing whether the data received by the communication equipment is 0xaa, if so, continuing to increase the initial delay time to 104 microseconds, and sending the data 0xaa to the communication equipment by the test equipment based on the delay time of 104 microseconds. And comparing whether the data received by the communication equipment is 0xaa, if so, continuing to increase the initial delay time, and if the data received by the communication equipment is not the data 0xaa sent by the test equipment until the first delay time is adjusted to 105 microseconds, recording the normal delay time 104 microseconds of the communication before the communication is abnormal as the second delay time.
And S140, determining a target delay time for communication with the test equipment according to the first delay time and the second delay time.
Wherein, the target delay time refers to the actual time used by the communication device to communicate the received data.
Specifically, an average value of the first delay time and the second delay time is calculated, and the average value is used as the target delay time. For example, if the first delay time obtained by the above steps is 102 microseconds and the second delay time is 104 microseconds, the finally determined target delay time is 103 microseconds.
The technical scheme of the embodiment determines the initial delay time according to the baud rate of the communication equipment, and communicates with the test equipment according to the initial delay time to obtain a communication result; when the communication result shows that the communication is abnormal, adjusting the initial delay time until the communication is normal to obtain a first delay time; adjusting the first delay time until the communication is abnormal to obtain a second delay time; and determining a target delay time for communicating with the test equipment according to the first delay time and the second delay time. That is, in the embodiment of the present invention, the theoretical delay time is not directly used for communication, but an actual communication delay time (i.e., a target delay time) is obtained through communication test measurement, and the actual communication delay time is used for communication, so that the communication success rate can be improved.

Fig. 2 is a flowchart of a communication method according to a second embodiment of the present invention, where this embodiment is applicable to a case of single-wire serial port adaptive communication, and the present embodiment is optimized based on the above embodiment, and reference may be made to any of the above embodiments for technical details that are not described in detail in this embodiment. In this embodiment, determining the initial delay time according to the baud rate of the communication device includes: determining theoretical delay time according to the baud rate; and determining the initial delay time according to the theoretical delay time. Adjusting the initial delay time until the communication is normal to obtain a first delay time, comprising: and increasing the initial delay time until the communication is normal to obtain a first delay time.

As shown in fig. 2, the method of this embodiment specifically includes the following steps:
and S210, determining theoretical delay time according to the baud rate.
Wherein the theoretical delay time refers to a time theoretically used for communicating the received data calculated based on parameters of the communication device.
Specifically, the internal oscillation frequency of different communication devices is different, the internal oscillation frequency of the communication device is determined according to the different communication devices, and the baud rate has different calculation methods according to different working modes of serial ports of the communication devices. In the present embodiment, the operation mode 0 of the serial port of the communication device is selected, and therefore the baud rate is a fixed baud rate obtained by dividing the oscillation frequency by 12. And the theoretical delay time value of the communication equipment is one-half of the baud rate. That is, if the Baud rate of the communication device is 9600Baud, the theoretical delay time is 1/9600 sec, 104 μ sec.
And S220, determining initial delay time according to the theoretical delay time.
Specifically, the theoretical delay time is reduced to obtain the initial delay time. In the present embodiment, the theoretical delay time is generally reduced to 0.5 to 0.6 times of itself as the initial delay time.
And S230, communicating with the testing equipment according to the initial delay time to obtain a communication result.
And S240, when the communication result shows that the communication is abnormal, increasing the initial delay time until the communication is normal to obtain a first delay time.
Specifically, communication is performed between the communication device and the test device according to the initial delay time obtained in the above steps, and the communication result is communication abnormality because the initial delay time is only 0.5 to 0.6 times of the theoretical delay time. On the basis of the initial delay time, increasing the unit delay time to the initial delay time, communicating between the communication equipment and the test equipment on the basis of the increased delay time, if the communication is abnormal, continuing to increase the initial delay time until the communication between the communication equipment and the test equipment is normal, and recording the delay time when the communication is normal as the first delay time.
And S250, increasing the first delay time until the communication is abnormal to obtain a second delay time.
Specifically, the initial delay time is continuously adjusted and increased through the step S240 until the first delay time when the first communication is normal is obtained. And on the basis of the first delay time, increasing the unit delay time to the first delay time, carrying out communication between the communication equipment and the test equipment on the basis of the increased delay time, if the communication is normal, continuously increasing the initial delay time until the communication between the communication equipment and the test equipment is abnormal, and recording the delay time when the communication is abnormal at the previous time as the second delay time.
And S260, calculating the average value of the first delay time and the second delay time, and taking the average value as the target delay time.
Specifically, the average value of the first delay time and the second delay time obtained by the above steps is obtained by adding and dividing the two delay times, and the obtained average value is the actual time used by the communication device for communicating and receiving data.
According to the embodiment of the invention, the initial delay time is adjusted according to the communication result between the communication equipment and the test equipment, the first delay time and the second delay time of two endpoint times in a normal communication time area are obtained, the target delay time is determined according to the average value of the first delay time and the second delay time, and the target delay time is used for communication, so that the communication success rate can be improved.
EXAMPLE III
Fig. 3 is a flowchart of a communication method according to a third embodiment of the present invention, where this embodiment is applicable to a case of one-line serial port adaptive communication, and the present embodiment is optimized based on the foregoing embodiment, and reference may be made to any of the foregoing embodiments for technical details that are not described in detail in this embodiment. In this embodiment, communicating with the testing device according to the initial delay time to obtain a communication result includes: receiving test data sent by test equipment according to the initial delay time; and comparing the test data with the preset data, obtaining a communication result indicating normal communication when the test data is the same as the preset data, and obtaining a communication result indicating abnormal communication when the test data is different from the preset data.
As shown in fig. 3, the method of this embodiment specifically includes the following steps:
s310, determining initial delay time according to the baud rate of the communication equipment, and receiving test data sent by the test equipment according to the initial delay time.
The test data refers to data sent by the test equipment and actually received by the communication equipment. Since the communication between the test device and the communication device may be abnormal, the data received by the communication device is not necessarily the data transmitted by the test device.
Specifically, the communication device calculates the baud rate according to the parameters thereof, calculates the theoretical delay time according to the baud rate, and reduces the theoretical delay time to 0.5 to 0.6 times of the baud rate as the initial delay time. The delay time parameter of the communication device is set to an initial delay time, and based on the initial delay time, the communication device receives data transmitted by the test device.
And S320, comparing the test data with the preset data, obtaining a communication result indicating normal communication when the test data is the same as the preset data, and obtaining a communication result indicating abnormal communication when the test data is different from the preset data.
The preset data refers to data to be sent by preset testing equipment.
Specifically, the test data actually received by the communication equipment is compared with the preset data sent by the test equipment, and if the test data actually received by the communication equipment is the same as the preset data sent by the test equipment, the successful communication between the communication equipment and the test equipment is indicated, and a communication result with normal communication is obtained; if the test data actually received by the communication equipment is different from the preset data sent by the test equipment, the communication failure between the communication equipment and the test equipment is indicated, and a communication result with abnormal communication is obtained.
Further, before the communication device communicates with the test device to transmit data, the communication device and the test device protocol the data to be transmitted. After the communication equipment receives the test data, the received test data is returned to the test equipment, so that the test equipment can obtain a communication result based on the current delay time by comparing the sent preset data with the received data, and further determine whether to continue sending the test data to the communication equipment.
And S330, when the communication result shows that the communication is abnormal, adjusting the initial delay time until the communication is normal to obtain a first delay time.
S340, adjusting the first delay time until the communication is abnormal to obtain a second delay time.
And S350, determining a target delay time for communicating with the test equipment according to the first delay time and the second delay time.
For example, taking the communication device as an MCU and the test device as a computer, the default data to be transmitted by both the MCU and the computer before communication data transmission is 0 xaa. Based on the initial delay time, the computer sends the preset data 0xaa to the MCU, the MCU receives the test data and then compares whether the test data is the preset data 0xaa, if not, the initial delay time is automatically adjusted, and the data actually received by the MCU is returned to the computer. Due to errors caused by the error between the initial delay time and the theoretical delay time, the data received by the computer is definitely not 0xaa, indicating abnormal communication. The computer repeatedly sends preset data 0xaa to the MCU, the actual data received by the MCU is not 0xaa, and the delay time is continuously increased; when the delay time is increased to a certain value, the test data received by the MCU is the same as the preset data sent by the computer, namely the communication between the MCU and the computer is normal based on the current delay time, and the current delay time is recorded as the first delay time. The computer continuously transmits preset data 0xaa to the MCU, the MCU compares whether the preset data is 0xaa after receiving the test data, if so, the MCU continuously increases the delay time, when the delay time is increased to a certain time value, the test data received by the MCU is inconsistent with the preset data transmitted by the computer, namely, the communication between the MCU and the computer is abnormal based on the current delay time, and the current delay time is recorded as a second delay time. And calculating the average value of the first delay time and the second delay time, taking the average value of the two delay times as the target delay time of the MCU, and setting a successful communication mark of the serial port of the MCU.
Fig. 4 is a flowchart of another communication method according to a third embodiment of the present invention, in which an oscillation frequency of a communication device is first set, a baud rate is determined according to the oscillation frequency, and a delay time is calculated after the oscillation frequency and the baud rate of the communication device are determined. And then, the test equipment continuously sends the same data, and the current delay time is recorded after the data received by the communication equipment is the same as the data sent by the test equipment. And when different data are received again, the test equipment stops sending and records the current delay time. And calculating the target delay time according to the two delay times. And finally, setting the delay time of the communication equipment as a target delay time to realize single-wire serial communication.
According to the embodiment of the invention, the communication result is obtained by comparing the test data actually received by the communication equipment with the preset data sent by the test equipment. And adjusting the delay time according to the communication result, further obtaining the target delay time and improving the success rate of communication.
