Technical Field
The invention relates to the fields of agricultural data acquisition, agricultural machine monitoring, industrial embedded equipment and the like, in particular to a method for remotely upgrading software of agricultural machine deep scarification Internet of things terminal equipment.
Background
With the rapid development of the internet of things, the relevance and adaptation between a terminal unit in the internet of things and a network are referred to as the direction concerned by technicians in the field, and whether an operation terminal can be upgraded in time directly affects the scale limitation, the function limitation and the intercommunication limitation of the internet of things. The situation is more prominent in the field of agricultural machinery internet, and agricultural machinery internet terminals are mostly installed on specific agricultural machinery, and operating personnel of agricultural machinery are not necessarily familiar with debugging or maintenance of agricultural machinery internet terminal equipment, so that once the situation that agricultural machinery interconnection or agricultural machinery monitoring fails due to the problem of terminal upgrading occurs, the application of the agricultural machinery internet of things is inevitably influenced. In addition, because the distribution of agricultural machinery internet of things terminal equipment is wide, it is not practical to simply rely on professional technicians to conduct field guidance or debugging to conduct software upgrading.
In conclusion, how to find a method for upgrading terminal software of the agricultural machinery internet of things is a key point of continuous research of technical personnel in the field, and the technical idea has higher requirements on upgrading efficiency, accuracy and integrity.
For example: chinese patent document CN102163157A provides a non-intelligent terminal upgrading method, a non-intelligent terminal and an application server, where the non-intelligent terminal upgrading method includes: sending upgrading request information containing the software version number to an application server; receiving a software upgrading package sent by an application server according to a software version number, wherein the software upgrading package comprises upgrading calling interface address mapping information generated according to a calling interface address mapping table corresponding to the software version number; and storing the software upgrading package in a storage unit so that the operating system calls the software upgrading package. Although the non-intelligent terminal comprises an upgrade request module, a software receiving module and a storage indication module, if the non-intelligent terminal is applied to the agricultural machinery internet of things terminal, the terminal cannot request the upgrade information from the application server because the latest software version information is not contained in the terminal.
Chinese patent document CN104850422A discloses a method for remotely updating a terminal device program, which includes first obtaining a version to be updated of a terminal device from a data server through a communication server, then feeding back current version information by the terminal device and generating a confirmation version information, and finally confirming an updated program version according to the information, then sending data of the program version to the terminal device, and the terminal device receiving and rewriting the program to complete a process of remotely updating the terminal device program. According to the scheme, the versions are not confused by generating a plurality of pieces of confirmation information and judging, but two servers are required to communicate with the terminal, and if the scheme is applied to the agricultural machinery Internet of things terminal, the flow consumption is high due to the fact that an interaction protocol is complex.
Chinese patent document CN110647337A provides an internet of things MCU air firmware upgrading method, which includes the following steps: providing an Internet of things MCU (microprogrammed control unit) air firmware upgrading system, wherein the Internet of things MCU air firmware upgrading system comprises a cloud control platform and a plurality of equipment groups, and each equipment group comprises a plurality of Internet of things terminals which are of the same type, provided with MCUs and in communication connection with the cloud control platform; the cloud control platform is additionally provided with the upgrading requirement of the Internet of things MCU firmware; the terminal of the Internet of things uploads the current MCU firmware version to the cloud control platform after being awakened; the cloud control platform selects one or two Internet of things terminals for upgrading verification; after judging whether each Internet of things terminal needs to be upgraded or not, the cloud control platform sends a corresponding MCU firmware upgrade address to the Internet of things terminal needing to be upgraded for batch upgrade; and the Internet of things terminal downloads the MCU firmware, then upgrades the MCU firmware and reports the result to the cloud control platform. Compared with the related technology, the method for upgrading the Internet of things MCU aerial firmware can reduce enterprise recall cost. According to the scheme, the MCU adopts the cloud platform to send the upgrading instruction, so that the method is suitable for the online condition of the terminals of the Internet of things in batches, and if the method is applied to the terminals of the Internet of things of agricultural machines, the terminals of the Internet of things of agricultural machines are in a dispersed and offline state, so that the terminals of the Internet of things miss the upgrading condition.
In addition, the technical field can solve the problem that the equipment realizes remote software upgrading through a wireless transport technology in the operation process by utilizing the OTA technology. In the existing GPRS terminal equipment market, particularly in the Internet of things equipment market of industry and agriculture, the OTA function has the defects of low practicability, low flexibility, no support of breakpoint continuous transmission, high failure rate, complex interaction protocol, high flow consumption, incapability of ensuring data integrity and the like.
Disclosure of Invention
Aiming at the defects of the prior art, the invention discloses a method for remotely upgrading software of terminal equipment of an agricultural machinery subsoiling Internet of things.
The detailed technical scheme of the invention is as follows:
a method for remotely upgrading software of agricultural machinery subsoiling Internet of things terminal equipment is disclosed, wherein the method comprises an OTA system, and is characterized in that the OTA system comprises: the agricultural machine Internet of things terminal is a terminal for uploading data through a GPRS module, and the GPRS module adopts a network transparent transmission mode and requests the data to the HTTP server through a serial port simulation HTTP protocol frame format; wherein the loading program in the agricultural machinery thing networking terminal includes: BootLoader terminal bootstrap program and app application program; the BootLoader terminal bootstrap program is a main program part for realizing remote upgrading; the app application program is a software part which is actually required to be remotely upgraded by a user, the latest version of the app application program is placed in the HTTP server, and an upgraded version detection function module is added in the app application program; the version detection function module is used for judging whether the executed app program needs to be backed up or not by comparing the new version number with the old version number, and if the backup is needed, the upgraded software and the version number are backed up simultaneously. Preferably, the GPRS module is preferably a domestic "manned" GPRS module, and it is noted that: the GPRS module only supports FTP remote upgrading and does not support HTTP remote upgrading.
By designing the firmware, the invention has the advantages that the OTA adopted for upgrading the Internet of things software in the technical field realizes online upgrading through the network or the GPRS, and the whole transmission technical scheme is hidden even if the upgrading software data is sent in an http mode, so that technicians in the field cannot upgrade and manage the agricultural Internet of things terminal software by adopting the content of the prior art, and the technical inspiration for improving and upgrading a domestic control terminal for reference is absent.
According to the invention, a software version management interaction platform is preferably also loaded in the HTTP server of the OTA system and is used for maintaining the app application program. The software version management interaction platform can limit password access to only software maintainers and administrators.
According to the preferable selection of the invention, the specific method for remotely upgrading the software of the agricultural machinery subsoiling Internet of things terminal device comprises the following steps:
after the agricultural machinery internet of things terminal is powered on, configuring the domain name and the port number of a GPRS module as the domain name and the port number of a remotely-upgraded HTTP server;
sending a version request frame to an HTTP server, and returning the latest version number to the agricultural machinery Internet of things terminal by the HTTP server according to the request instruction;
the agricultural machinery internet of things terminal compares the latest version number with a locally stored version number: if the version numbers are the same, upgrading is not needed; if the version numbers are different, upgrading is needed;
when upgrading is needed, the agricultural machinery Internet of things terminal sends an upgrading data request frame to the HTTP server, and the HTTP server packs corresponding data according to the initial position and the number of bytes of the request data and replies the packed data to the agricultural machinery Internet of things terminal;
the agricultural machinery Internet of things terminal checks after receiving the data: if the data verification of the current packet fails, reapplying the packet data until the verification is successful; and continuing to request the next data packet until the terminal requests all the upgrading data.
According to the invention, preferably, in the process of software remote upgrade, if the software upgrade fails due to bad signals, the processing is carried out according to the preset threshold value of failure times: and if the failure times exceed the failure time threshold, giving up upgrading of the agricultural machinery Internet of things terminal, and directly jumping to the standby app for execution. As shown in fig. 1.
According to the preferable selection of the invention, the method for remotely upgrading the software of the agricultural machinery subsoiling Internet of things terminal equipment further comprises the following steps:
in the process of software remote upgrading, the serial port interacts with the GPRS module at a default baud rate: and if the information interaction is not successful, sequentially changing the baud rate to communicate with the GPRS module until the serial port can normally communicate with the GPRS module. Preferably, in order to reduce the adaptation time, the commonly used baud rates (e.g., 115200, 9600, etc.) may be preferentially placed in the front alignment; if the communication is carried out, the upgrading can be continued at the baud rate of the communication.
The technical advantages of the invention include:
(1) according to the invention, through optimization of hardware and software, a conventional HTTP server is continuously used, so that a new server is not required to be built again when the software is remotely upgraded, and development and maintenance costs are reduced.
(2) The invention improves the domestic GPRS module in the prior art, so that even if the GPRS module does not support HTTP remote upgrade, the network transparent transmission mode of the GPRS module can be adopted after improvement, and data can be requested to a server by simulating the frame format of the HTTP protocol through a serial port.
The invention can realize the integration and upgrade of the existing domestic device (especially the internet of things terminal with a domestic GPRS module) to meet the requirement of software upgrade, and the improved scheme is as follows: adding a new software upgrading interface in a software management window of a software product management platform, and providing the authority for logging in, uploading and maintaining an app application program. Secondly, customizing a special BootLoader, wherein the customized content mainly comprises the following steps: and planning a storage area according to the FLASH resources of the CPU, customizing a proprietary upgrade domain name according to the type of the newly added upgrade software, and customizing the domain name and the port of the application server according to the actual app application requirement. And thirdly, adding a version detection function package at the app application program end, and correspondingly changing the operation starting address of the program.
(3) In order to improve the flexibility of the server side software version management, the invention adds a software management window on the product management platform, so that operation and maintenance personnel can upload the latest software upgrade version in time without requesting at a request side.
(4) In order to reduce flow consumption, whether software upgrading is needed or not can be checked only by actively requesting version information by the agricultural machinery Internet of things terminal in the early stage, the protocol is simple, and the version checking work is more efficient.
(5) In order to improve the accuracy and the high efficiency of remote upgrading work, the invention designs a breakpoint continuous transmission function, when the upgrading data is larger, the upgrading data is divided into a plurality of small packets for data request, so that the situation that the whole upgrading data needs to be requested again due to data loss caused by poor signals or long connection is avoided; the function of breakpoint resume is such that: even if the data request of the packet fails, the previously requested packet data is not lost, and only the failed packet data is repeatedly requested.
(6) In order to improve the integrity of data, the invention adds data verification to each packet of data continuously transmitted at the breakpoint so as to ensure the integrity of each packet of data and improve the success rate of the whole upgrade.
(7) The invention aims to enhance the applicability of the practical application of remote upgrading and increase an upgrading fault-tolerant mechanism. The fault tolerance mechanism comprises: if the server cannot be connected due to poor signals in the upgrading process, if repeated connection threshold times are unsuccessful, the server is considered to be failed in upgrading, and the server jumps to the standby version to operate, so that the crash condition caused by unsuccessful upgrading can be avoided. Secondly, the serial port is configured by 115200 baud rate as a default during upgrading, but if the GPRS baud rate is modified in an application program, the serial port cannot be upgraded normally, and a fault-tolerant mechanism of self-adaptive baud rate is designed to solve the problem. The self-adaptive baud rate means that the serial port interacts with the GPRS module at a default baud rate in the upgrading process, if the serial port does not interact with the GPRS module, the baud rate is sequentially changed to communicate with the GPRS module until the serial port can normally communicate with the GPRS module, wherein in order to reduce self-adaptive time, the common baud rates (such as 115200, 9600 and the like) can be preferentially compared in front; if the communication is carried out, the upgrading can be continued at the baud rate of the communication. Before remote upgrading, whether the version number of the server is the same as that of the locally stored version number needs to be detected, upgrading is carried out only if the version numbers are different, and upgrading is not needed if the version numbers are the same. The version number cannot be stored to the local when the upgrade fails, the version number cannot be stored until the upgrade succeeds, otherwise, the version number cannot be upgraded again due to the same version. The solution of the invention is: and storing the updated new version into the standby area at the BootLoader, detecting whether the version is changed in the application program after the update is successful and the jump is successful to the application program, and changing the running version number if the version is changed. And fourthly, in order to adapt to the server domain name and the port required by the application program, the domain name and the port are configured for GPRS before jumping from the BootLoader terminal bootstrap program to the app application program, the domain name and the port are suitable for the domain name and the port actually used in the app application program, and a user can customize the special BootLoader terminal bootstrap program according to different product requirements.
(8) In order to meet the actual application requirements, the invention also adds the parameter configuration function of the GPRS module, and has the technical advantages that when the factory default configuration of the GPRS module does not conform to the configuration required by remote upgrade, or when the configuration of the GPRS module is changed by an app application program due to service needs, the upgrade fails due to the mismatch between the GPRS configuration and the remote upgrade configuration, and the added parameter configuration function can automatically update the GPRS configuration parameters.
