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 application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For better understanding of the embodiments of the present application, technical terms or partial terms that may be referred to in the embodiments of the present application are explained as follows:
1. firmware is a program written in EPROM (erasable programmable read only memory) or EEPROM (electrically erasable programmable read only memory). The firmware refers to a device "driver" stored in the device, and through the firmware, the operating system can implement the operation of a specific machine according to the standard device driver, for example, the optical disc drive and the recorder have internal firmware. Firmware is software that acts as the most basic and bottom layer of a system. In a hardware device, the firmware is the soul of the hardware device, and because some hardware devices have no other software components except for the firmware, the firmware determines the functions and performances of the hardware device.
2. An Integrated Development Environment (IDE, also called Integration Design Environment, Integration debug Environment) is application software that assists program developers in developing software, and can assist in writing source code text, compiling and packaging into usable programs, and some of them can even Design graphical interfaces.
NB-IoT is short for narrow-band Internet of Things (Narrowband Internet of Things), and is the LPWAN radio standard specified by 3GPP in order to allow mobile devices and services to be more remote. This standard was specified in 3GPP Release 13 (LTE Advanced Pro) at month 6, 2016. Other 3GPP internet of things technologies include eMTC (enhanced machine type communication) and EC-GSM-IoT. NB-IoT is particularly focused on indoor coverage, low cost, long battery life, and high connection density. NB-IoT uses part of the long term evolution technology standard, but limits the bandwidth to a single narrow frequency of 200 kHz. NB-IoT uses OFDM modulation to process downlink communications and SC-FDMA to process uplink communications.
4. General Packet Radio Service (english: General Packet Radio Service, abbreviation: GPRS) is one mobile data Service/technology that GSM mobile phone users can use. It is often described as "2.5G", meaning that this technology is intermediate between second generation (2G) and third generation (3G) mobile communication technologies. It utilizes unused TDMA channel in GSM network to provide medium speed data transmission service. Initially, one wanted to extend GPRS to cover other standards, except that these networks are turning to use the GSM standard, so GSM became the only network that GPRS could use. GPRS was integrated into the GSM standard after Release 97, which was first standardized by ETSI, but now has been handed over to the responsibility of 3 GPP.
The Web server generally refers to a website server, refers to a program residing on a certain type of computer on the Internet, can process requests of Web clients such as a browser and the like and return corresponding responses, and can also place website files for browsing all over the world; data files can be placed for download all over the world. Currently, the three most popular Web servers are Apache, Nginx, and IIS.
6. Broadband (english: Broadband) is a method of simultaneously transmitting many electronic messages using multiple frequencies over basic electronic and electronic communications. It describes a wide range of frequencies that a signal or electronic circuit contains or is capable of handling simultaneously. Broadband is a relative description, and the larger the frequency range, i.e. the higher the bandwidth, the more data that can be transmitted relatively increases. For example, in radio communication, a relatively narrow frequency range can only transmit morse code, and a relatively large bandwidth is required to transmit high-quality music. The broadband of a television antenna represents the ability to receive a relatively large number of channels. In terms of data transmission, the telephone line is also used as a signal transmission medium, the optical fiber cable is more and more popular, the Modem can only transmit data at 64Kbps per second, and the broadband ADSL and optical fiber Modem can provide higher transmission rate.
In the application of the internet of things equipment, remote data telemetry and control are mostly needed to be realized, even the equipment is needed to be used remotely, and the situation that the function is few and even the on-site equipment has bug may exist in the previous design of the equipment. At present, part of electric vehicles may adopt a remote Over the air technology, abbreviated as OTA, to upgrade firmware inside the electric vehicle.
Generally speaking, remote firmware upgrade requires real-time communication between a device and a cloud platform, requires the device to download data from the cloud platform, and realizes automatic upgrade after a series of calculations and checks. Generally, in the firmware file upgrading process, if a firmware file is large, breakpoint resuming is often needed, and devices with complete operating systems, such as android, windows, linux, and the like, have the function, and in the fields of low-end devices, such as 8-bit chips, 16-bit chips, and the like, android, windows, or linux operating systems cannot be embedded, so that the breakpoint resuming function needs to be developed autonomously.
In addition, in the upgrading process, the communication means adopted between the low-end embedded chip and the web server is also a low-speed and low-bandwidth communication mode, such as gprs and nbiot modes, and the communication is often unstable, and frequent disconnection conditions exist, so that the complete firmware file is difficult to download at one time.
In the related art, as shown in fig. 1, a "breakpoint resume" mechanism is often simulated to realize downloading, checking, and segment file reassembly of firmware segments, and to ensure that an upgrade program is started without error.
The specific implementation steps are as follows:
1. successful firmware compilation by computer through IDE
2. And verifying the firmware function and the performance index.
3. And after the test is finished, calculating a verification value of the firmware, wherein the verification value is the md5 value or the crc32 value of the firmware.
4. And (5) building a web server with http1.1 and publishing the firmware and the check value to the web server.
5. The remote device communicates with the web server via gprs or other low-rate communication means to obtain and store the firmware and the check value. In this step, in the process of upgrading by using low-rate communication modes such as gprs and nboot, the server uses a protocol above http1.1, the remote device uses a breakpoint continuous transmission method in the http1.1 protocol to obtain file contents with a size not exceeding 1 kbyte, the remote device obtains relevant ' fragments ' of the firmware by the method, and then recombination of the ' fragments ' is realized by combination, however, under the condition of low-rate communication, the obtained ' fragments ' have errors, so the ' wrong ' fragments cannot be upgraded after combination, and once upgraded, the remote device may become ' bricks ' (i.e., unusable) '.
6. And calculating a check value of the firmware, comparing the check value with a check value of the web server, automatically starting upgrading of the equipment if the check values are consistent, and ensuring the stability of the power supply of the equipment in the upgrading process. Therefore, in the related art, it is further necessary to continuously send a corresponding check value to the server in the process of acquiring the segment, so that the remote device can perform real-time check after acquiring the segment, and once the check value is not matched, the "segment" is continuously acquired until the segment is correctly acquired.
In accordance with an embodiment of the present application, there is provided an embodiment of a device update method, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
