Description

File transmission method, electronic equipment and storage medium

Technical Field

Background

At present, when some electronic devices with low memory (such as a smart watch) transmit files, bluetooth connection is usually performed with a mobile phone, the files to be transmitted are transmitted to the mobile phone side through a bluetooth channel, and then the files are transmitted to a server through the mobile phone. However, the transmission rate of bluetooth transmission is about 100KB/s, which requires a lot of time when a file is transmitted, and if the file is transmitted for too long, transmission failure is easily caused, and the efficiency of file transmission is low.

The client referred to in the technical solution of the present application mainly refers to an electronic device with a low memory and supporting cellular mobile data service, for example, a smart watch, where a RAM (Random Access Memory ) space of the smart watch is generally 32M.

In the technical scheme of the application, the class (Cat) of the Modem (Modem) is improved, and correspondingly, a higher-speed physical transmission channel is switched, so that the client can transmit the file by using the cellular mobile data. Compared with the traditional scheme of transmitting files through Bluetooth, the method and the device can dynamically switch the mode of Bluetooth transmission into cellular transmission when the files to be transmitted are large, the rate of file transmission can be remarkably improved, meanwhile, the possibility of transmission failure is also reduced due to improvement of the transmission rate, and the efficiency of file transmission is further improved.

The Cat class is used to measure the modem technology capability and the supported data transfer speed, among other things. The higher the Cat level, the stronger the wireless connection performance of the client, and the faster the transmission speed. In the embodiment of the present application, the initial level of the modem is generally Cat1, which generally has a low data transmission speed, and is suitable for basic communication requirements. The preset target level is greater than the initial level, and the preset target level is the Cat level supported by the modem. After the Cat level is raised, the modem needs to be restarted to validate the underlying service handoff of the modem, thereby successfully switching the Cat level from the initial level to the preset target level.

In the related art, when transmitting a file, some electronic devices (such as a smart watch) with low memory typically make bluetooth connection with a mobile phone, and transmit the file to be transmitted to the mobile phone side through a bluetooth channel, and then transmit the file to a server through the mobile phone. However, the transmission rate of bluetooth transmission is about 60KB/s, which requires a lot of time when a file is transmitted, and if the file is transmitted for too long, transmission failure is easily caused, and the efficiency of file transmission is low.

In view of this, the embodiments of the present application provide a file transmission method, an electronic device, and a storage medium, where a client may transmit a file by using cellular mobile data by increasing the Cat level of a modem and switching a higher-speed physical transmission channel accordingly. Compared with the traditional scheme of transmitting files through Bluetooth, the method and the device can dynamically switch the mode of Bluetooth transmission into cellular transmission when the files to be transmitted are large, the rate of file transmission can be remarkably improved, meanwhile, the possibility of transmission failure is also reduced due to improvement of the transmission rate, and the efficiency of file transmission is further improved.

The following illustrates an application scenario of the file transmission method provided in the embodiment of the present application;

the method and the device can be applied to a smart watch test (Beta) stage, in the stage, in order to analyze and position the conversation type problem and the stability problem of the modem, the modem log and the Dump (Dump) log are required to be uploaded to the mobile phone through Bluetooth, and the mobile phone can upload log files to a server by utilizing own cellular mobile data. In order to meet the positioning of the modem maintenance problem, at least 60M modem logs and 60M Dump files need to be transmitted, the transmission rate of Bluetooth transmission is very low, meanwhile, other modules of the intelligent watch in the test stage also need to transmit logs through Bluetooth, the logs of other modules can be occupied when the log files are large, secondly, the transmission channel is blocked due to the fact that the log uploading time is too long, and the logs are uploaded by other modules. In order to solve the above problem, the file transmission method provided by the embodiment of the present application may switch the bluetooth transmission mode to cellular transmission, so as to improve the efficiency of log uploading.

The file transmission method provided in the embodiment of the present application is described in detail below by taking a client side and a server side as examples.

First, a detailed description will be given of a file transfer method provided in the embodiment of the present application, taking a client side as an example.

Referring to fig. 1, a flow chart of a file transmission method provided in an embodiment of the present application is shown. As shown in fig. 1, the file transfer method is applied to a client, and may include the following steps:

in step 101, in response to a transmission instruction of a file to be transmitted, the modem is started to connect to the cellular mobile network.

In practical application, the client in the embodiment of the application may be configured in an electronic device with a small memory capacity, such as a smart watch, an internet of things (Internet of Things, ioT) device, an embedded system, and a vehicle-mounted device, and simultaneously support data connection and communication of cellular mobile data. The internet of things equipment further comprises intelligent home equipment, an intelligent safety system, a sensor and the like; the embedded system further comprises: remote monitoring equipment, traffic signal lamps, intelligent electric meters and the like; the vehicle-mounted equipment also comprises a vehicle navigation system, a vehicle networking system and the like.

Among them, a modem is a device for converting digital signals into analog signals (modulation) and converting analog signals into digital signals (demodulation) for implementing functions of client connection to the internet, remote communication, data transmission, etc.

In one possible implementation manner, the transmission instruction may be sent by an instruction client, where a file transmission option may be set on the instruction client, and the user may generate the transmission instruction by clicking on the file transmission option, then instruct the client to send the transmission instruction to a task scheduling module of the client, where the task scheduling module is responsible for coordinating various matters of file transmission in the client, and in a log uploading scenario, the task scheduling module may be a DFX (Design for X, design for each link of a product life cycle). The instruction client may be configured in a mobile phone, a computer, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (augmented reality, AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (personal digital assistant, PDA), and other various electronic devices that are convenient for a user to operate.

In another possible implementation manner, the transmission instruction may be obtained directly by receiving an operation instruction of the user, that is, a file transmission option may be directly set on the client, and the client may directly obtain a transmission instruction generated by the user clicking on the file transmission option, and execute a subsequent file transmission task according to the transmission instruction.

In this embodiment of the present application, when receiving a transmission instruction of a file to be transmitted, the client may start the modem through a corresponding command or setting, for example, a modem control interface provided by an operating system, or by an application program or a device management tool. After the modem is started, the client connects with the cellular mobile network, wherein the processes include the client communicating with the base station of the network operator through the modem, and performing the processes of identity verification, network registration and the like. After establishing a connection with the cellular mobile network, the client may activate the mobile data service by sending a corresponding request through the modem, e.g. sending a specific command or activating a data plan to the network operator, who will verify the client's request and activate the mobile data service according to the subscription plan and the service contract.

Step 102, switching the class level of the modem from the initial level to a preset target level.

The class level, that is, cat class, is a standard defined by 3GPP (3 rd Generation Partnership Project, third generation partnership project) for measuring modem technology capability and supported data transmission speed, and the higher the Cat class, the stronger the wireless connection performance of the client and the faster the transmission speed.

In this embodiment of the present application, the data transmission speed of the preset target level is greater than the data transmission speed of the initial level. The initial level of the modem is typically Cat1, which generally has a low data transmission rate, and is suitable for basic communication requirements. The preset target level is greater than the initial level, and the preset target level is the Cat level supported by the modem. In general, the preset target level is set to Cat4, which is suitable for most file transfer scenarios. It should be noted that, the higher the Cat level is, the greater the power consumption of the client is, so the preset target level cannot be set too high, and the determination needs to be performed in combination with the actual application scenario and the requirement.

As a possible implementation manner, after the Cat level is promoted, the modem needs to be restarted to enable the underlying service handover of the modem to be effective, so that the Cat level is successfully switched from the initial level to the preset target level, that is, in a possible implementation manner of the embodiment of the present application, the step 102 may include: the class level of the modem is adjusted to a preset target level; the modem is restarted to switch the class level of the modem from the initial level to a preset target level. Wherein the modem may be restarted by restarting the client or switching on and off the flight mode. Wherein, it is more convenient, swift to restart the modem through the switch flight mode. It should be noted that, after the flight mode is turned on, the mobile network of the client may wait for several seconds or more to ensure that the mobile network of the client is completely turned off, and then the flight mode is turned off, and the mobile network of the client is re-enabled.

In one possible implementation, the process of switching modem Cat class may be performed by a micro control unit (Microcontroller Unit; MCU) in the client, which comprises a task scheduling module and a cellular dimension module, wherein cellular dimension (Cellular Network Testing) refers to the process of testing and measuring a cellular mobile communication network. Cellular interferometry encompasses the evaluation and analysis of network performance, signal strength, data transmission rate, coverage, etc. After receiving the instruction of the Cat class switching, the micro control unit can call an interface of the cellular maintenance module, and the cellular maintenance module can inform the modem to adjust the Cat class through an AT command (AT commands), and can re-read a Non-Volatile Memory (NV) through a switch flight model after the switching is successful, so that the bottom service switching is effective. Wherein the AT command is a standard command set for communicating with and controlling the modem for configuring and managing the modem, and uses a standard ASCII character format, prefixed with "AT" as a command, followed by a specific command code and parameters. By sending different AT commands to the device, various operations may be performed, such as querying device information, configuring device parameters, sending a short message, making a call, etc., e.g., if the Cat class of the modem is to be switched to Cat4, the AT command may be at+supecat=4. NV is a type of memory commonly used in small electronic devices to store data that remains unchanged after the device is powered down, and thus has very good data retention capabilities, and when the cellular survey re-reads the NV through a switched flight mode, re-reads and loads the device configuration and parameters stored in the NV memory, helping to clear possible network connectivity problems, refresh the device configuration, and re-establish efficient communication between the device and the cellular network.

Step 103, switching the physical transmission channel from the serial peripheral interface to the universal serial bus interface.

It should be noted that, the physical transmission channel corresponding to the initial level of the modem is a serial peripheral interface (Serial Peripheral Interface, SPI), and the physical transmission channel corresponding to the preset target level is a universal serial bus interface (Universal Serial Bus, USB). The serial peripheral interface is a serial communication protocol, which is generally used for short-distance data transmission, the transmission rate of the serial peripheral interface is relatively low, and is generally below tens of MHz, and the serial peripheral interface has the problems of transmission error, interference and the like and is easily influenced by the surrounding environment. The transmission rate and reliability of the serial peripheral interface may be limited in transmission scenarios of large data volumes and in high noise interference environments. In contrast, the universal serial bus interface is a high-speed parallel communication protocol, can support data transmission rates up to 10Gbps, and has good anti-interference capability and transmission reliability. Therefore, after the modem is re-resident, the transmission channel between the micro control unit and the modem is switched from the serial peripheral interface to the universal serial bus interface, so that the data transmission rate and reliability can be obviously improved, and the normal operation of high-speed data transmission can be ensured.

Referring to fig. 2, a schematic flow chart of a client promoting Cat class and switching physical transmission channels is shown. As shown in fig. 2, after receiving a command for switching Cat levels, the task scheduling module in the micro control unit invokes the cellular measurement interface, executes a command of at+supecat=4, modulates the Cat level of the modem into Cat4, switches the modem on and off in a flight mode, re-reads NV to enable the bottom service switching to be effective, further switches the serial peripheral interface to be a universal serial bus interface, queries the current Cat level by executing the command of at+supecat=0 to ensure that the Cat level has been successfully switched, and finally sends a switching result to the task scheduling module.

Step 104, after the cellular mobile network is connected, the file to be transmitted is transmitted to the server based on the modem and the universal serial bus interface of the preset target level.

After the Cat class and the physical transmission channel are switched, the file to be transmitted can be transmitted to the server at a higher rate in a cellular transmission mode.

In the embodiment of the present application, the client has two modes of transmitting files, one is bluetooth transmission, and the second is cellular data transmission. The Bluetooth transmission is a default file transmission mode, and when the files to be transmitted are smaller and the file transmission tasks are fewer, the power consumption of the client can be saved through the Bluetooth transmission mode. However, when the file to be transmitted is large and the file transmission task is more, the bluetooth transmission can be switched to the cellular data transmission by responding to the cellular uploading instruction sent by the user, so that the efficiency of file transmission is improved.

Furthermore, before file transmission, a connection between the client and the server needs to be established, the address of the server may be obtained first, and then the modem and the server may be communicated and a connection may be established according to the address of the server and through the HTTP protocol. Specifically, an HTTP request may be created using software or an application on the modem, then the address of the server is resolved to an IP address, then a network connection is established with the server through a cellular mobile data network (e.g., 2G, 3G, 4G, 5G, etc.) using the network function of the modem, the created HTTP request is further sent to the IP address of the server, and the response of the server is awaited, and the modem processes the response after receiving the response of the server. Through the above steps, the modem can communicate with the server and establish a connection using the HTTP protocol.

In addition, before file transmission, a transmission path of the server needs to be acquired, and the file to be transmitted is read into the memory in a buffer manner so as to be sent to the server later. In the log uploading scenario, after the file to be transmitted is transmitted, the log service (LogService) file is required to be successfully uploaded, and the log service file is used for recording key information such as events, errors, warnings, debugging information and the like generated in the running process of the client so as to facilitate subsequent fault detection, problem analysis and system optimization.

Further, while increasing the Cat level of the modem may increase the speed of file transfer, it also means that the modem needs to occupy more bandwidth and power consumption. Therefore, after the file transmission is finished, the Cat level needs to be reduced in time, so that excessive network bandwidth and electric quantity of the client can be prevented from being wasted after the file transmission is finished, and the client can operate more reasonably, stably and efficiently.

Accordingly, the Cat level of the modem is switched back to the initial level, and the physical transmission channel is the same, and compared with the serial peripheral interface, the power consumption rate of the universal serial bus interface is relatively higher, so that the physical transmission channel can be switched from the universal serial bus interface to the serial peripheral interface when the file to be transmitted is transmitted to the server.

In one possible implementation manner, in order to facilitate the user to obtain the progress of log transmission in real time, the client may obtain the file transmission result sent by the server in real time in the process of transmitting the file to be transmitted, and determine and display the file transmission progress based on the file transmission result. The file transmission progress may be directly displayed on the client, or may be displayed on an instruction client connected to bluetooth of the client, which is not limited in this application.

According to the file transmission method provided by the embodiment of the application, the client side improves the Cat grade of the modem and correspondingly switches the higher-speed physical transmission channel, so that the client side can transmit the file by using the cellular mobile data. According to the method and the device, when the file to be transmitted is large, the Bluetooth transmission mode is dynamically switched to cellular transmission, the file transmission rate can be remarkably improved, meanwhile, the possibility of transmission failure is also reduced due to improvement of the transmission rate, and the file transmission efficiency is further improved.

In one possible implementation manner of the present application, compared to an electronic device with a larger memory, such as a smart phone, a RAM space of the smart phone is generally 8GB or even higher, and a RAM space of a client in the embodiment of the present application is smaller, so that a space available for file caching by the client is very small. Therefore, when the client needs to transmit the file, the file to be transmitted can be re-sliced, sequentially transmitted, and the server background re-aggregates the sliced files after the transmission is completed to obtain the file to be transmitted. The method for transmitting the file in the slicing mode can effectively solve the problem that the RAM space of the client is insufficient and large files cannot be transmitted.

The file transmission method provided in the embodiment of the present application is further described below with reference to fig. 3.

Referring to fig. 3, a flowchart of another file transfer method provided in an embodiment of the present application is shown. As shown in fig. 3, the file transfer method may include the steps of:

in step 301, in response to a transmission instruction of a file to be transmitted, the modem is started to connect to the cellular mobile network.

Step 302, switching the class level of the modem from the initial level to a preset target level.

The data transmission speed of the preset target level is larger than the data transmission speed of the initial level.

Step 303, switching the physical transmission channel from the serial peripheral interface to the universal serial bus interface.

The specific implementation and principles of the steps 301 to 303 may refer to the detailed description of the foregoing embodiments, which is not repeated herein.

And 304, slicing the file to be transmitted to obtain a plurality of subfiles corresponding to the file to be transmitted.

It should be noted that, when the client with larger memory uploads the file through the cellular, the client can implement automatic aggregation in the server background by applying for a plurality of URLs (Uniform Resource Locator, uniform resource locators). The client memory referred to in the embodiment of the present application is small, and the space available for file caching is very small, and the existing uploading mechanism cannot be compatible, so that slicing processing needs to be performed on the file to be transmitted.

The file name of the sub-file comprises a file sequence number, and the file name of the sub-file with the largest file sequence number also comprises an end mark.

In one possible implementation, when the file transfer service module of the client reads a larger file, the file transfer service module may read the larger file in buffers (buffers), each Buffer is a sub-file of the file to be transferred, and the size of the sub-file may be 1M, and then the sub-file is transferred to a modem, and the modem renames the transferred Buffer. Taking a log uploading scenario as an example, the naming rule of the same file to be transmitted when the fragments are named can be as follows: product name_version number_imei_timestamp_single number_device_modemlog_file number log, wherein the file number is: starting with 1, the last file is appended sequentially, e.g., 1,2, 3..100, with an end flag "end" such as "xxx_modemlog_end. Log" appended to the sequence number.

And 305, sequentially transmitting each sub-file to the server according to the file sequence number corresponding to each sub-file until the sub-file with the file name including the end mark is transmitted.

The process of sequentially transmitting each subfile to the server is performed under the condition of the modem and the usb interface of the preset target level after the cellular mobile network is connected, and specific reference may be made to the detailed description of the foregoing embodiments, which is not repeated herein.

In this embodiment of the present application, after each of the segment subfiles is uploaded to the server, the server performs recognition and re-aggregation according to the file name, and finally generates a download link.

Referring to fig. 4, a schematic flow chart of a slice transmission in a log upload scenario is shown. As shown in fig. 4, the completion log file is first sliced to obtain a plurality of subfiles: and the modemLog_1 and the modemLog_2 … … modemLog_N … … modemLog_end are sequentially transmitted to the server according to the file serial numbers until the transmission of the subfiles with the file names including the end mark end is completed, and then the server background aggregates the sliced subfiles to obtain the complete modem log file to be uploaded.

In one possible implementation manner, in order to facilitate the user to obtain the progress of log transmission in real time, the client may generate and display the file transmission progress in real time by obtaining the file transmission result sent by the server for each sub-file in the process of transmitting each sub-file.

According to the file transmission method, when the client needs to transmit the file, the file to be transmitted is re-sliced, sequentially transmitted, and the server background re-aggregates the sliced files after the transmission is completed, so that the file to be transmitted is obtained. The method for transmitting the file in the slicing mode can effectively solve the problem that the RAM space of the client is insufficient and large files cannot be transmitted.

The file transmission method provided in the embodiment of the present application is described in detail below by taking a server side as an example.

Further, because the RAM space of the client is small, the space available for file caching by the client is minimal. Therefore, when the client needs to transmit the file, the file to be transmitted can be re-sliced, sequentially transmitted, and the server background re-aggregates the sliced files after the transmission is completed to obtain the file to be transmitted. That is, in one possible implementation manner of the embodiment of the present application, the receiving the file to be transmitted by the client may include: receiving a plurality of subfiles transmitted by a client, wherein the subfiles are obtained by slicing a file to be transmitted by the client, the file names of the subfiles comprise file serial numbers, and the file names of the subfiles with the largest file serial numbers also comprise end marks; and after the transmission of the subfiles with the file names comprising the ending marks is finished, aggregating all subfiles according to the file serial numbers corresponding to the subfiles to obtain the files to be transmitted.

In one possible implementation manner, in order to facilitate the user to obtain the progress of log transmission in real time, the server may generate the file transmission result of the file to be transmitted in real time in the process of receiving the file to be transmitted; and sending the file transmission result to the client so that the client can determine and display the file transmission progress based on the file transmission result. The server can want the client to return the file transmission result of the sub-file when receiving one sub-file, so that the file transmission progress generated by the client is more accurate; the server may also return the file transmission result of the subfiles received in the period of time at intervals, or return the file transmission result of the fixed number of subfiles once every time a fixed number of subfiles is received, for example 10, so that excessive resource consumption of the client and the server can be avoided.

Fig. 5 is a schematic data interaction diagram of a file transmission method according to an embodiment of the present application.

As shown in fig. 5, the file transfer method includes the steps of:

in step 501, the client starts a modem to connect to a cellular mobile network in response to a transmission instruction of a file to be transmitted.

In step 502, the client switches the class level of the modem from the initial level to a preset target level.

In step 503, the client switches the physical transmission channel from the serial peripheral interface to the universal serial bus interface.

In step 504, the client transmits the file to be transmitted to the server based on the modem and the usb interface of the preset target level after the cellular mobile network connection.

In step 505, the server receives a file to be transmitted by the client.

In the above process, the client side promotes the Cat level of the modem and accordingly switches the higher-speed physical transmission channel, so that the client side can transmit the file by using the cellular mobile data. According to the method and the device, when the file to be transmitted is large, the Bluetooth transmission mode is dynamically switched to cellular transmission, the file transmission rate can be remarkably improved, meanwhile, the possibility of transmission failure is also reduced due to improvement of the transmission rate, and the file transmission efficiency is further improved.

Referring to fig. 6, a schematic flow chart of a file transfer method in a log uploading scenario is shown. As shown in fig. 6, taking a client side as a smart watch and an instruction client side as a mobile phone as an example, firstly, a user clicks a log uploading button in the mobile phone by using the mobile health APP (because the mobile health APP is strongly related to the smart watch) and checks a cellular uploading switch, a task scheduling module receives the transmission instruction, and performs the operations of powering up a modem, activating cellular mobile data service, switching Cat4, switching a flight mode, reconnecting a network, the task scheduling module further notifies a file transmission service module to transmit a file, the file transmission service module reads the file in fragments, transmits a slicing sub-file to a log server on a server side through the modem, returns a transmission result to the file transmission service module after the slicing sub-file is successfully transmitted, and then transmits the transmission result to the mobile health APP side, so as to display the transmission progress, and after all log transmission is completed, the file transmission service module notifies the task scheduling module to notify the modem to power down, reduce Cat level, and the log server further aggregates fragmented sub-files, links to a log downloading website, wherein the log downloading service can provide visual downloading service, so as to analyze the problems of the log downloading website and the call stability.
