Detailed Description
The core of the invention is to provide a single-wire communication method and a system, which avoid the simultaneous entering of the master device and the slave device into a sending mode, thereby preventing the data transmission from being blocked and improving the stability of communication.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a single-wire communication method according to an embodiment of the present invention.
The single-wire communication method is applied to a master device which performs data communication with a slave device in single-wire communication, and comprises the following steps:
step S1: first verification data is sent to the slave device.
Step S2: and receiving data information returned from the equipment.
Step S3: whether a communication line connecting the master and slave devices is in a communicable state is determined based on the content of the data information.
Specifically, in order to avoid that the master device and the slave device enter a transmission mode at the same time, which causes a blockage in data transmission of a communication line connecting the master device and the slave device, the present application provides a method of determining whether the communication line connecting the master device and the slave device is in a communicable state, so that the master device and the slave device communicate only when the two communication lines are in a communicable state.
More specifically, the principle of determining the state of the communication line connecting the master and slave devices is as follows: when the master device and the slave device do not perform data communication, namely, the master device and the slave device are in an idle state, the master device sends first check data to the slave device. After receiving the first check data, the slave device indicates that the communication lines of the slave device and the master device are in a state that the slave device can send data to the master device, and if the slave device has a communication requirement with the master device, the slave device can send slave communication data to the master device; after receiving the slave communication data, the master device returns corresponding master communication data according to the slave communication data, and the master device and the slave device enter data communication; if the slave device does not have a need to communicate with the master device at this time, second parity data matching the first parity data is returned. After receiving the second check data, the master device indicates that the communication line between the master device and the slave device is in a state that the master device can send data to the slave device, and similarly, if the master device has a communication requirement with the slave device at this time, the master device can send master communication data to the slave device; after receiving the master communication data, the slave equipment returns corresponding slave communication data according to the master communication data, and the slave equipment and the master communication data enter data communication; if the master device does not have a need to communicate with the slave device at this time, the first check data may continue to be sent to the slave device.
Based on this, when the master device and the slave device do not perform data communication, the master device sends first check data to the slave device and then waits for data information returned by the slave device, and after receiving the data information returned by the slave device, the master device can judge whether the communication lines of the master device and the slave device are in a communicable state according to the content of the data information, so that stable communication between the master device and the slave device is realized.
The invention provides a single-wire communication method, when a master device and a slave device do not carry out data communication, the master device sends first check data to the slave device, and the slave device returns second check data to the master device after receiving the first check data. After starting data communication, the master device waits for second check data returned by the slave device, and sends master communication data to the slave device after receiving the second check data, and the master device and the slave device enter data communication. After starting data communication, the slave device waits for first check data sent by the master device, and sends slave communication data to the master device after receiving the first check data, and the master device and the slave device enter data communication. Therefore, the single-wire communication method avoids the master device and the slave device from entering a sending mode simultaneously, thereby preventing data transmission from being blocked and improving the stability of communication.
On the basis of the above-described embodiment:
as an alternative embodiment, the process of determining whether or not a communication line connecting the master and slave devices is in a communicable state based on the content of the data information includes:
and if the data information is second check data matched with the first check data, determining that the communication line connecting the master device and the slave device is in a communicable state.
Specifically, considering that the master device receives the second check data, the two communication lines are in a state where the master device can transmit data to the slave device, and therefore, after receiving the data information returned by the slave device, the master device determines that the two communication lines are in a communicable state if detecting that the data information is the second check data, that is, the master device can transmit the master communication data to the slave device.
As an alternative embodiment, the process of determining whether or not a communication line connecting the master and slave devices is in a communicable state based on the content of the data information includes:
if the data information is slave communication data transmitted from the slave device, it is determined that the communication line connecting the master device and the slave device is in a communicable state.
Specifically, after receiving the slave communication data sent by the slave device, the master device and the slave device are in a state where the slave device waits for the master device to return the corresponding master communication data, so that after receiving the data information returned by the slave device, the master device determines that the two communication lines are in a communicable state if detecting that the data information is the slave communication data sent by the slave device, specifically, the master device needs to return the corresponding master communication data to the slave device at this time.
As an alternative embodiment, the process of sending the first check data to the slave device includes:
sending first check data to the slave device;
and returning to the step of sending the first check data to the slave equipment if the second check data returned by the slave equipment has no communication requirement with the slave equipment.
Specifically, when the master device and the slave device do not perform data communication, the master device transmits first check data to the slave device. When the slave device returns the second parity data to the master device, it is indicated that the slave device does not have a need to communicate with the master device at this time. If the master device does not have the requirement for communication with the slave device after receiving the second check data returned by the slave device, the master device continues to send the first check data to the slave device, so that when the master device and the slave device do not perform data communication, the master device periodically sends the first check data to the slave device until the master device and the slave device enter data communication.
As an alternative embodiment, the single-wire communication method further includes:
transmitting master communication data to the slave device when the communication line is in a communicable state;
and starting timing when the master communication data is transmitted, and quitting data communication if the slave communication data returned by the slave equipment is not received when the timing time reaches the preset first time.
Further, the master device may transmit the master communication data to the slave device when it determines that the communication line is communicable based on the content of the data information after receiving the data information returned from the slave device. The master device can also start timing from the time of sending the master communication data, and if the slave communication data returned by the slave device is not received when the timing time reaches the preset first time, the master device exits the data communication and enters a state of sending the first check data to the slave device after considering that the communication between the master device and the slave device is finished.
As an alternative embodiment, the single-wire communication method further includes:
and starting timing from the time of sending the first check data, and determining that the communication with the slave equipment is interrupted if the data information returned by the slave equipment is not received when the timing time reaches the preset second time.
Furthermore, the master device may start timing from when the first check data is sent, and if the data information returned by the slave device is not received when the timing time reaches the preset second time, which indicates that the communication between the master device and the slave device is interrupted and the device may have a fault, the master device may control a prompting device (such as an indicator lamp or a vibrator) to send a prompting message indicating that the communication is interrupted at this time, so that the user can view the prompting message.
As an optional embodiment, the first check data includes a transmission identifier for characterizing transmission of data from the master device to the slave device, a byte length for characterizing a size of the first check data, and a data field;
the second check data comprises a receiving identification used for representing that the master device receives the data returned by the slave device, a byte length used for representing the size of the second check data and a data field.
Specifically, the first check data of the application comprises a sending identifier, a byte length and a data field, and the second check data comprises a receiving identifier, a byte length and a data field; the sending identifier is used for representing that the master device sends data (such as 01) to the slave device, the receiving identifier is used for representing that the master device receives data (such as 02) returned by the slave device, the byte length is used for representing the size of the check data, and the data field is used for writing data with certain information content.
As shown in table 1 below, the content of the transmission/reception identifier occupies 2 bytes, the content of the byte length occupies 2 bytes, and the data field can be written with 4 kbytes of data content at most.
TABLE 1
| Transmitting/receiving identification | Length in bytes | Data field |
| 2bytes | 2bytes | 4k bytes(max) |
More specifically, the master communication data sent by the master device to the slave device is in the same form as the first check data, and comprises a sending identifier, a byte length and a data field; the difference is that the data field of the first check data is null data; the data field of the master communication data is written in the communication content of the master device and the slave device. Similarly, the slave communication data sent from the slave device to the master device is in the same form as the second check data, and comprises a receiving identification, a byte length and a data field; the difference is that the data field of the second check-up data is null data; and writing the communication content of the slave device and the master device from the data field of the communication data.
Based on this, the process of the master device detecting whether the data information returned by the slave device is the second check data includes (please refer to fig. 2): judging whether a data field of the data information is a null field, if so, judging whether the identification content of the data information is a receiving identification, and if so, determining that the data information returned from the equipment is second check data; if the received identification is not the received identification, determining that the data information returned from the equipment is not second check data; and if the check-up data is not the null field, determining that the data information returned from the device is not the second check-up data.
Similarly, the process of the master device detecting whether the data information returned by the slave device is slave communication data includes (see fig. 3): judging whether a data field of the data information is an empty field, if not, judging whether the identification content of the data information is a receiving identification, and if so, determining that the data information returned by the slave equipment is slave communication data; if the received identification is not the received identification, determining that the data information returned by the slave equipment is not slave communication data; and if the field is empty, determining that the data information returned by the slave device is not slave communication data.
