In order to illustrate the technical solutions described in the present application, the following description is made by means of specific examples.
Referring to fig. 1, a schematic flowchart of a communication method of a diagnostic device provided in an embodiment of the present application is shown, where the method includes:
step S1, when the diagnosis equipment triggers communication operation, a historical communication mode recorded in a configuration file of the diagnosis equipment is obtained.
In application, when the diagnostic equipment triggers a communication operation, the historical communication mode recorded in a pre-stored configuration file in the diagnostic equipment can be obtained when the startup of the diagnostic equipment is detected or when the startup of diagnostic software in the diagnostic equipment is detected; even if the diagnostic software is still standing and then receives the operation of the user, the communication is needed. The historical communication mode recorded in the pre-configuration file may be a mode for indicating that the diagnostic device is communicating with the external device last time.
For example, in a specific application scenario, when it is detected that the diagnostic device is turned on or the diagnostic software in the diagnostic device is turned on, the communication mode of the diagnostic device is automatically selected to perform communication, and the process of automatically selecting the communication mode of the diagnostic device is to first acquire the historical communication mode recorded in the configuration file of the diagnostic device.
And S2, communicating with external equipment by adopting the historical communication mode.
In the application, after the history communication mode is obtained in step S101, the communication is performed with the external device through the history communication mode. The historical communication mode can be a communication mode which can be supported by diagnostic equipment based on USB communication, bluetooth communication, WIFI communication and the like.
In one embodiment, referring to fig. 2, the communication with the external device using the history communication method includes steps S211 to S214:
step S211, when the history communication mode is a USB communication mode, detecting whether there is a first external device connected to the diagnostic device through a USB interface.
Specifically, when the acquired history communication mode is a USB communication mode, it is detected whether an external device connected through a USB interface exists in a device manager of the diagnostic device, and if the external device is connected through the USB interface, the external device is used as the first external device.
Step S212, if the first external device exists, acquiring a first product identification code and a first vendor identification code of the first external device.
Specifically, if the first external device exists, the product identification code PID and the vendor identification code VID of the first external device are obtained, and are referred to as a first product identification code and a first vendor identification code, respectively. If a plurality of first external devices exist, the first product identification codes and the first provider identification codes of the plurality of first external devices are respectively acquired.
Step S213, after the first product identifier and the first vendor identifier are obtained, detecting whether the diagnostic device has a first serial port corresponding to the first product identifier and the first vendor identifier; the first serial port is used for indicating a serial port corresponding to a USB interface for connecting the first external device.
Specifically, the product identifier and the vendor identifier may be used to distinguish the types of devices, and the devices of different types may have different corresponding first serial ports, so that it may be detected whether the diagnostic device has the first serial port corresponding to the first product identifier and the first product vendor. The first serial port is a serial port corresponding to a USB interface for connecting the first external device.
Step S214, if the first serial port exists, communicating with the first external device through the first serial port.
Specifically, if the first serial port exists, it indicates that the first external device and the diagnostic device can communicate through a USB communication mode, the first serial port can be adopted to communicate with the first external device at this time, and if information returned through the first serial port is received within a first preset time, it is determined that the communication between the first serial port and the external device is successful, and at this time, the first serial port and the diagnostic device can communicate with the external device through the USB communication mode to perform data interaction. If the information returned by the first serial port is not received within the first preset time, the communication failure between the USB communication mode and the external equipment is judged.
In one embodiment, referring to fig. 3, the communicating with the external device by using the historical communication method includes:
step S221, when the history communication mode is a Bluetooth communication mode, obtaining second serial port information used by the history communication mode.
Specifically, when the historical communication mode is a bluetooth communication mode, the configuration file stores information such as the serial number and the baud rate of the last bluetooth communication mode, and the serial number and the baud rate of the bluetooth communication mode of the historical record can be obtained from the configuration file. The second serial port information includes, but is not limited to, serial port number and baud rate information of bluetooth communication.
Step S222, communicating with the external device through a second serial port corresponding to the second serial port information.
Specifically, an instruction is sent to an external device according to a serial port (called a second serial port) of bluetooth communication and a baud rate used in the history. And sending a preset Bluetooth communication instruction to external equipment within a preset effective range through the serial port and the corresponding baud rate of the last Bluetooth communication record. If the information returned by the corresponding external equipment is received within the second preset time, the Bluetooth communication based on the second serial port is judged to be successful, and meanwhile, the communication with the corresponding external equipment based on the Bluetooth communication mode is also judged to be successful.
Step S223, if communication with the external device fails according to the second serial port, acquiring an available third serial port in the diagnostic device.
Specifically, after the bluetooth communication according to the second serial port fails, the device manager obtains an available serial port, which is called a third serial port; the device manager is a management tool, and can display serial port information which can work normally, and the third serial port does not comprise the second serial port.
In step S224, communication is performed with the external device through a third serial port.
Specifically, when a plurality of available third serial ports are obtained through the device manager, an instruction is sent to the external device through each third serial port and the corresponding baud rate in sequence until one of the third serial ports is successful in communication, communication is performed with the external device through the successful third serial port, and namely the serial port corresponding to Bluetooth communication is determined. If the communication corresponding to all the third serial ports fails, judging that no serial port suitable for Bluetooth communication exists, and judging that the Bluetooth communication fails. And judging that the serial communication is successful can be that after the corresponding serial and baud rate send the instruction to the external equipment, and receiving the information returned by the external equipment within the second preset time, judging that the corresponding serial communication is successful.
In one embodiment, the communicating with the external device using the historical communication method includes: detecting and connecting WIFI when the historical communication mode is a WIFI communication mode; after being connected to the WIFI, the wireless communication system communicates with external equipment through the WIFI communication mode.
Specifically, when the history communication mode of acquireing is the WIFI communication mode, detect the WIFI signal, after detecting the WIFI signal, be connected with the WIFI equipment that sends the WIFI signal, when detecting a plurality of WIFI signals, can be connected with the WIFI equipment that corresponds to send the WIFI signal according to the sign of prestored WIFI equipment, the external equipment that said here is the WIFI equipment that sends the WIFI signal. The communication with the external device through WIFI may be performed by sending a PING command to the external device. If the information returned based on the PING command is received within the third preset time, judging that the communication with the external equipment through the WIFI is successful; if the information returned based on the PING command is not received within the third preset time, the communication failure between the external equipment and the WIFI is judged.
In application, for example, when the diagnostic device is a diagnostic box, the diagnostic box can send a WIFI signal when the external device is the diagnostic box, the diagnostic device is in communication connection with the diagnostic box through the WIFI sent by the diagnostic box, and the diagnostic box can be connected with an automobile through an OBD interface of the automobile.
And step S3, if the communication between the historical communication mode and the external equipment fails, communicating with the external equipment by adopting a target communication mode, wherein the target communication mode is other communication modes supported by the diagnosis equipment except the historical communication mode.
Specifically, if the communication between the historical communication mode and the external equipment fails, other communication modes supported by the diagnosis equipment are used for communicating with the external equipment until one communication mode is successful, and the current successful communication mode is used for communicating with the external equipment.
In one embodiment, referring to fig. 4, the communication with the external device using the target communication method includes steps S311 to S312:
step S311, if the target communication manner includes at least two target communication manners, acquiring a pre-stored priority ranking order of the at least two target communication manners.
Specifically, the priority ranking sequence of the communication modes supported by the diagnostic equipment can be prestored, after the diagnostic equipment and the external equipment establish communication failure through the historical communication modes, the priority ranking sequence of all the target communication modes supported in the diagnostic equipment is obtained according to the prestored priority ranking sequence, and the target communication modes are other communication modes except the historical communication modes with the communication failure.
Step S312, according to the priority ranking order, selecting a corresponding target communication mode from high to low according to the priority to communicate with the external device until any one of the at least two target communication modes is successfully communicated with the external device.
Specifically, according to the priority ranking sequence, the corresponding target communication modes are sequentially selected from high to low according to the priority ranking sequence to communicate with the external equipment until any one of all the target communication modes is successful in communicating with the external equipment, and then the data interaction is carried out with the external equipment by adopting the successful communication mode.
In application, the communication modes supported by the diagnostic device include USB communication, bluetooth communication and WIFI communication, when the prestored communication mode is the highest level USB communication, the second highest level communication mode is the WIFI communication mode, and the third highest level communication mode is the bluetooth communication mode. When the determined historical communication mode is a USB communication mode, the communication is carried out with the external equipment according to the WIFI communication mode and the Bluetooth communication mode in sequence. When one of the communication modes is successful, the communication mode is adopted to carry out data interaction with the external equipment.
In one embodiment, after the communication with the external device in the target communication manner, the method further includes: and if the target communication mode is adopted to successfully communicate with the external equipment, updating the historical communication mode recorded in the configuration file by using the target communication mode.
Specifically, the configuration file records a historical communication mode and communication information corresponding to the historical communication mode, for example, the communication information corresponding to the Bluetooth communication can be information such as a Bluetooth communication serial port and a corresponding baud rate, the USB communication can be a USB communication serial port, and the WIFI communication mode can be an identification of diagnostic equipment and an identification of external equipment. If the target communication mode is successful in communication with the external equipment, replacing the historical communication mode and the corresponding communication information recorded in the configuration file with the target communication mode and the corresponding communication information. If the historical communication mode is successful in communication with the external equipment, the communication mode is consistent with the last communication mode, and only the communication information of the historical communication mode is replaced.
In one embodiment, after the historical communication mode recorded in the configuration file of the diagnostic device is obtained when the diagnostic device triggers a communication operation, the method further comprises: if the historical communication mode is a preset unusual communication mode, the target communication mode is adopted to communicate with the external equipment, and the target communication mode is other communication modes except the historical communication mode supported by the diagnosis equipment.
Specifically, the unusual communication mode may be preset, if the historical communication mode is the preset unusual communication mode, the other communication modes except the historical communication mode are adopted to communicate with the external device, and after the other communication modes except the historical communication mode are used to communicate with the external device for identification, the preset unusual communication mode is adopted.
In application, if bluetooth is set as a preset mode which is not commonly used in the preset, when the historical communication mode is a bluetooth communication mode, a USB communication mode except bluetooth and a WIFI communication mode are adopted first, and after the USB communication mode and the WIFI communication mode fail, the bluetooth communication mode is adopted.
In one embodiment, when the communication between the history communication mode and the target communication mode and the external device fails, the communication failure is prompted, and specifically, the communication failure can be prompted by preset voice, text and/or pictures.
