Description
Technical Field
The embodiment of the invention relates to the technical field of software upgrading methods, in particular to a short data communication protocol upgrading method, device, system and storage medium based on a low earth orbit satellite.
Background
With the rapid development of electronic technology, communication technology and computer technology, embedded systems have been widely used in various fields, the requirements of various industries on the system function, performance and scale of embedded devices are increasing day by day, and developers must be able to maintain and upgrade the system in time according to the needs of customers to prolong the service life of the system and improve the performance of the system. At present, remote upgrading modes mainly comprise: the method adopts a structural design of Boot and double loaders to realize complete upgrade of the system, and an ARM software remote updating system based on a TFTP (Trivisual File Transfer protocol) protocol.
The operation of the embedded system is mainly divided into a working mode and an upgrading mode, wherein the working mode is a default mode, the working mode refers to a normal working state of the equipment, the embedded system completes corresponding measurement and control tasks according to a preset program, and reports monitoring parameters to a monitoring management center through internet, GPRS and other modes. The upgrading mode refers to that the embedded type is in an upgrading state and comprises the steps of receiving program codes sent by a server, solidifying the program codes in a flash area and the like.
The whole upgrading system mainly comprises a server and a remote terminal, wherein the remote terminal comprises an embedded control chip based on an ARM core and a Modem module. The two are connected through an RS232 bus, and the server and the remote terminal are communicated through the Internet. The server is used as an active initiator of a software upgrading task, firstly an upgrading command is sent to the embedded system, after hardware of the embedded system is started, a bootstrap program Bootloader is executed firstly to carry out a series of initialization operations, meanwhile, an upgrading control program is selected to be executed, after the server receives a confirmation upgrading reply of the embedded system, the server starts to send upgrading program codes, before the upgrading program codes are sent, the codes are divided into a plurality of data units with fixed lengths by the server, each data unit is taken as a core to form a data packet (the content of the data packet comprises a data packet head mark, a command head, a packet sequence, a data unit, a CRC (cyclic redundancy check) code, a data packet tail mark, a total packet number and the like), the embedded system returns confirmation information every time the embedded system receives one data packet, if the data packet is verified to be correct, erasing of an old program and copying of a new program are carried out in a specified FLASH area, therefore, the purpose of online upgrading of the embedded system software of the remote terminal is achieved.
The existing online upgrading mode is a mode of issuing the whole communication protocol to a terminal and then replacing the original communication protocol packet. This method has a large communication traffic, and even a fine parameter adjustment or a logic fine change will cause a large communication traffic. Under the WIFI or 4G mode, the network bandwidth between the terminal and the backup server is large, the delay is small, the size of a data frame is large, and great troubles cannot be caused by upgrading.
However, for the space-based internet of things of the low earth orbit satellite, especially for the narrow-band space-based internet of things, the traditional upgrading mode is not suitable. Firstly, the bandwidth allocated to a terminal by a satellite service network, especially a narrowband space-based internet of things, is only a few KB, the size of a message is generally tens of bytes, the delay is large, packet loss is common, and updating the whole firmware (several MB or tens of MB) is impossible. Second, terminals of the space-based internet of things are often deployed in relatively remote locations or where it is inconvenient for the owner to reach. For example: the terminal of the power tower on the Qinghai-Tibet plateau is not easy to be removed once; a terminal on the neck of a wild animal in the unmanned region; terminals on heavy construction machinery in a construction site, etc. It is not possible for the owner or manager of these communication terminals to use a laptop computer in the field to update the firmware of these terminals. In addition, the high construction cost and the operation cost of the base internet of things determine that the cost of the base internet of things is more expensive than the traffic cost of the cellular-based internet of things, and the communication protocol is updated to reduce the required traffic as much as possible.

Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. 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.
In a specific embodiment, the invention provides a communication protocol upgrading method based on a low earth orbit satellite, which is suitable for a space-based internet of things of the low earth orbit satellite to meet the requirement of low flow upgrading. The method is implemented based on the terminal framework shown in fig. 1 and a carrier, and the method is implemented by virtue of the terminal framework. Specifically, a well-designed software architecture is needed for maintainability of a terminal of the space-based internet of things, so as to ensure that a low-earth orbit satellite can safely, reliably and inexpensively update or upgrade a communication protocol. As shown in fig. 1, the terminal framework is divided into multiple layers, first, a hardware layer, a basic firmware layer, a service architecture layer, and a micro-service layer. The user's logic is centralized in the microservice layer, and the upgrade of the present invention is performed for this layer. The hardware layer comprises a control chip of the terminal, a memory bank, a peripheral sensor and the like. The basic firmware layer is on the BootLoader and the operating system foundation (kernel, driver and file system), and needs to provide a service language environment (a compiler or an interpreter of the service language, and an extension of the service language) which is convenient for users to use. Common service languages include MicroPython (embedded version of Python), Lua (portable scripting language), Low.js (embedded version of node.js) and the like, the languages shield the complexity of memory management, hardware driving and the like, and meanwhile, standard logic components such as a clock, a scheduler, a common data structure and the like can be provided, so that a user can focus on own business logic conveniently and quickly build a business logic program applicable to the industry. The micro service layer is divided into a core service and a user service: the core service exposes the common functions of the terminal hardware, and the user can control the bottom layer hardware by simply updating the attribute of the core service, such as the power saving strategy of the power supply module; network protocol addresses of networking modules, etc.; the user service provides script code and its attributes that focus on the user business logic. These services and attributes all have a unique numerical code. When inquiring or updating the attribute, the specified attribute can be located only by providing the service number and the attribute number.
As shown in fig. 2, the method comprises the steps of:
s1: acquiring an update type of a communication protocol to be upgraded, wherein the update type comprises an update attribute and an update service; in order to reduce complexity and communication flow in an FOTA (Firmware Over-The-Air) upgrading process, according to objective conditions of users, upgrading requirements of The users are divided into two conditions: firstly, the logic is unchanged, and only the configuration parameters of the service, namely the update attribute, need to be changed; and secondly, a certain micro service, namely an update service, needs to be replaced. After the updating types are divided, different updating processes can be conveniently designed for the two updating requirements in the follow-up process, and for the updating attribute, only the new value of the attribute to be updated needs to be transmitted in the updating process; for update services, the upgrade process transmits a compressed package of new services, which contains their new logic code and attribute definitions, etc.
S2: when the update type is judged to be the update attribute, generating and sending an attribute number carrying a new attribute value so that a terminal of the communication protocol to be upgraded receives the attribute number and updates the corresponding attribute according to the new attribute value corresponding to the attribute number; specifically, when the attribute is updated, the internet of things gateway constructs an attribute setting message, specifies a service number, establishes multiple groups of attribute numbers and new attribute values thereof, and transmits the attribute setting message to the terminal through the satellite channel.
S3: and when the update type is judged to be the update service, generating and sending an upgrade packet carrying a new service logic code and an initial attribute set so that a terminal of the communication protocol to be upgraded receives the upgrade packet and updates the corresponding service according to the decompressed upgrade packet. When updating service, the gateway of the internet of things packs the service to be updated to form an upgrade package, the upgrade package comprises service logic codes and an initial attribute set, the upgrade package is compressed and is issued to the terminal through a satellite channel, the service framework of the terminal decompresses the upgrade package to a service directory after receiving the upgrade package identification, modifies the service list, removes the old service entry and replaces the old service entry with a new service, and therefore service updating is completed.
In order to ensure the integrity and the security of the data, the check code can be synchronously sent to the terminal along with the upgrade packet. Specifically, when the update type is judged to be the update service, a check code is further generated and sent, the check code is used for verifying whether the upgrade package is complete, when the upgrade package is verified to be complete according to the check code, the upgrade package is decompressed, and the corresponding service is updated according to the decompressed upgrade package. When updating service, the gateway of the internet of things packs the service to be upgraded to form an upgrade package, the upgrade package comprises a service logic code and an initial attribute set, the upgrade package is compressed and attached with a check code and is issued to the terminal through a satellite channel, a service frame of the terminal verifies the integrity of the upgrade package according to the attached check code after receiving the upgrade package identification, and then the upgrade package is decompressed to a service directory. The service framework modifies the service list, removes the old service entry, and replaces it with the new service to complete the service update.
Further, after the corresponding service is updated according to the decompressed upgrade package, the method further includes:
restarting all services of the updated service layer. When the services are updated, all services of the service layer are required to be restarted instead of the specified services, because the services may have a dependency relationship, all the services are restarted, and the mutual reference of the services is guaranteed to be still effective.
Still further, the method further comprises:
verifying the service of the updated service layer;
and when the preset fault of any updated service is judged, returning the service version before updating. After updating the service, the service framework may monitor the new service and if a preset condition is not met (e.g., a dead loop is trapped, an error is frequently reported, etc.), roll back to the old service before to ensure the availability of the terminal.
In the foregoing embodiment, the method for upgrading a communication protocol based on a low earth orbit satellite according to the present invention divides upgrading of terminal software into attributes to be updated and dimensionalities of update services, and when the attributes need to be updated, only a logic code corresponding to a new attribute needs to be sent to a terminal, and it is not necessary to update the whole terminal code each time, so that the traffic cost for attribute updating is low, the traffic used for updating is reduced, and the demand for low traffic updating of the low earth orbit satellite is met.
In addition, the updating mode provided by the invention also reduces the risk generated in the updating process. Because the space-based internet of things terminal is generally deployed in a place where a manager cannot easily reach, once the upgrade fails, a field maintenance worker needs to be dispatched to manually find and connect the terminal again so as to reset the firmware, the labor cost is high, and the upgrade failure even faces the risk of losing connection of the terminal under some extreme conditions. Both of the two updating methods proposed herein include attribute and code verification, and a rollback mechanism when the boot fails, so that the risk in an over the air upgrade (FOTA) process can be greatly reduced.
In addition to the above upgrading method, the present invention further provides a communication protocol upgrading apparatus based on a low earth orbit satellite, as shown in fig. 3, the apparatus includes:

After the updating types are divided, different updating processes can be conveniently designed for the two updating requirements in the follow-up process, and for the updating attribute, only the new value of the attribute to be updated needs to be transmitted in the updating process; for update services, the upgrade process transmits a compressed package of new services, which contains their new logic code and attribute definitions, etc.
An attribute updating unit 200, where the attribute updating unit 200 is configured to generate and send an attribute number carrying a new attribute value when determining that the update type is an update attribute, so that a terminal of a communication protocol to be upgraded receives the attribute number, and updates a corresponding attribute according to the new attribute value corresponding to the attribute number; specifically, when the attribute is updated, the internet of things gateway constructs an attribute setting message, specifies a service number, establishes multiple groups of attribute numbers and new attribute values thereof, and transmits the attribute setting message to the terminal through the satellite channel.
A service updating unit 300, where the service updating unit 300 is configured to generate and send an upgrade packet carrying a new service logic code and an initial attribute set when determining that the update type is an update service, so that a terminal of a communication protocol to be upgraded receives the upgrade packet, and updates a corresponding service according to a decompressed upgrade packet. When updating service, the gateway of the internet of things packs the service to be updated to form an upgrade package, the upgrade package comprises service logic codes and an initial attribute set, the upgrade package is compressed and is issued to the terminal through a satellite channel, the service framework of the terminal decompresses the upgrade package to a service directory after receiving the upgrade package identification, modifies the service list, removes the old service entry and replaces the old service entry with a new service, and therefore service updating is completed.

The service framework modifies the service list, removes the old service entry, and replaces it with the new service to complete the service update.
The service updating unit is also used for restarting all the services of the updated service layer. When the services are updated, all services of the service layer are required to be restarted instead of the specified services, because the services may have a dependency relationship, all the services are restarted, and the mutual reference of the services is guaranteed to be still effective.
Further, the device service updating unit is further configured to verify services of the updated service layer, and return to the service version before updating when it is determined that a preset failure occurs in any updated service.
