In order to facilitate understanding of the technical scheme of the present invention, an application scenario of the technical scheme of the present embodiment is first introduced. Specifically, the service framework applied in the technical solution of the present embodiment may be a C (Client)/S (Server) architecture as shown in fig. 1A; the development board based on OpenHarmony3.2Release is used as a Client terminal, electric power terminal equipment needing equipment upgrading is used as a Server terminal, the Client terminal can be remotely connected with a plurality of Server terminals through an RS-485 bus, and remote data communication with the plurality of Server terminals is realized by using a modbus protocol.

Example 1
Fig. 1B is a flowchart of a remote upgrade method of an end device according to an embodiment of the present invention, where the method may be performed by a remote upgrade apparatus of an end device, the remote upgrade apparatus of the end device may be implemented in hardware and/or software, the remote upgrade apparatus of the end device may be configured in an electronic device, and typically, the electronic device may be an OpenHarmony development board. As shown in fig. 1B, the method includes:
s110, when an equipment upgrading instruction issued by a target client is detected, acquiring target end equipment corresponding to the equipment upgrading instruction, and sending an equipment information inquiry command to the target end equipment based on a modbus protocol.
The target client can be an application program written based on preset program voice and used for controlling the terminal equipment to carry out system upgrading. In this embodiment, a target client may be installed in the OpenHarmony development board in advance, and the target client may support operations such as adding, deleting, information viewing, and device upgrading of the peer device. Specifically, the user may select an end device that needs to be upgraded in the target client, and click on the device upgrade button to send a device upgrade instruction. The device upgrade instruction may include information such as an end device identifier, an instruction type, and the like.
Specifically, after receiving the device upgrade instruction, the OpenHarmony development board may parse the device upgrade instruction to determine an end device that needs to perform device upgrade, that is, a target end device. Then, a device information query command may be sent to the target device over a pre-deployed RS-485 bus based on the modbus protocol. After receiving the device information query instruction, the target device may feed its own device information, for example, the current system version, device attribute, etc., back to the OpenHarmony development board.
S120, receiving target equipment information corresponding to the equipment information query command fed back by the target end equipment, and forwarding the target equipment information to a cloud platform based on a curl protocol so that the cloud platform performs validity check on the target equipment information.
Specifically, after receiving the target device information, the OpenHarmony development board may encapsulate the target device information and then send the target device information to the cloud platform through a curl protocol; after receiving the target device information, the cloud platform may perform validity verification on the target device information according to a locally preset validity verification rule, for example, determine whether stored information matched with the target device information exists locally. Then, if the cloud platform determines that the target device information successfully passes the validity check, the cloud platform can generate and send check passing information to the OpenHarmony development board, and can issue an upgrade package required to be used for upgrading the current device to the OpenHarmony development board.
Secondly, if the cloud platform detects that the target device information fails to pass the validity check, the cloud platform can generate and send check failure information to an OpenHarmony development board so as to indicate that the device information of the target device is abnormal.
S130, when checking passing information fed back by the cloud platform is detected, an upgrade package issued by the cloud platform is received, and upgrade prompt information is generated and sent to the target terminal equipment.
Specifically, after detecting the verification passing information fed back by the cloud platform, the OpenHarmony development board can download an upgrade package issued by the cloud platform to the local, and can generate rules according to preset prompt information, for example, take the upgrade package information as upgrade prompt information and the like, generate upgrade prompt information corresponding to the upgrade package, and further can send the upgrade prompt information to the target terminal device based on a modbus protocol. The target terminal equipment can be an information acquisition terminal in the electric power field.
After the target device receives the upgrade prompt information successfully, a confirmation instruction can be generated and fed back to the OpenHarmony development board so as to indicate that the device upgrade is ready.
And S140, when a confirmation instruction corresponding to the upgrade prompt information fed back by the target terminal equipment is detected, sending the upgrade package to the target terminal equipment, so that the target terminal equipment performs equipment upgrade based on the upgrade package.
Specifically, after receiving a confirmation instruction fed back by the target end device, the OpenHarmony development board may transmit an upgrade packet to the target end device based on a modbus protocol; after receiving the upgrade package, the target device may parse the content of the upgrade package based on the data structure of the modbus protocol to obtain upgrade data, and attempt to upgrade the device based on the upgrade data.
Wherein, the upgrade package is based on a modbus protocol, and each data frame is 2048 bytes; the method comprises the steps of setting a default initial value corresponding to a current upgrade package round field to be 1, wherein 2 bytes correspond to a register address field, 2 bytes correspond to a register number field, 2 bytes correspond to a total upgrade package round field, and 2 bytes correspond to the current upgrade package round field.
It should be noted that, the single frame data of the modbus protocol is limited to 256 bytes, and the upgrade package in this embodiment is generally larger, so that the transmission time will be increased. In order to solve the above problems, the present embodiment modifies the modbus protocol, and expands each frame of data to 2048 bytes by expanding the number of registers of the protocol, so that the transmission time of the upgrade package can be optimized to the same level as that of directly transmitting data through the serial port.
Optionally, the data frame may further include at least one of a destination device identification field, a function code field, a byte number field, an upgrade packet data field, and a cyclic redundancy check field.
In a specific example, the message structure of the modbus protocol data frame may be as shown in table 1. The target end equipment identification field consists of 1 byte, and the value range is 0x 01-0 x64, and respectively represents 1-100 end equipment; the function code field corresponds to 1 byte, and the value represents the function of the data frame and can be identified by the slave station; register address and number fields respectively corresponding to two bytes, wherein the values respectively represent the initial address of data and the number of registers and can be identified by the slave station; a byte number field, the value representing the total number of bytes of data; the total upgrade package round field corresponds to two bytes, and the value represents the total number of retries of upgrade failure; the current upgrade package corresponds to two bytes, and the value indicates the current time for transmitting the upgrade file; the upgrade package data field may correspond to N bytes, with a value representing the data content actually used to perform the device upgrade.
Table 1 message Structure of modbus protocol data frame
It should be noted that, the terminal device does not need to migrate the Libmodbus protocol stack, and only needs to receive data through the RS-485 bus, parse the modbus protocol data in a fixed format, and encapsulate the modbus protocol data packet to answer the OpenHarmony device.
And S150, when a successful restart notification sent by the target terminal equipment is detected, determining that the target terminal equipment is upgraded.
Specifically, after the target device performs device upgrade based on the received upgrade package, the target device needs to restart the device to take effect of the upgrade. After a successful restart, the target device may generate a successful restart notification to send to the OpenHarmony development board. When receiving a successful restart notification sent by the target device, the OpenHarmony development board can determine that the target device is successfully upgraded, and can send a notification message of the success upgrade to the target client.
Optionally, if the OpenHarmony development board does not receive the successful restart notification fed back by the target device within the preset time threshold, the OpenHarmony development board indicates that the device upgrade of the current round fails, and at this time, the upgrade package may be sent again according to the preset total upgrade package round until the successful restart notification fed back by the target device is received, or the total upgrade package round is reached.
According to the technical scheme, the OpenHarmony development board is used for acquiring target end equipment corresponding to the equipment upgrading instruction after detecting the equipment upgrading instruction issued by the target client, and sending an equipment information inquiry command to the target end equipment based on a modbus protocol; then, receiving target equipment information corresponding to an equipment information query command fed back by target end equipment, and forwarding the target equipment information to a cloud platform based on a curl protocol so as to enable the cloud platform to perform validity check on the target equipment information; when checking passing information fed back by the cloud platform is detected, receiving an upgrade package issued by the cloud platform, and generating and sending upgrade prompt information to target end equipment; when a confirmation instruction corresponding to the upgrade prompt information fed back by the target end equipment is detected, an upgrade package is sent to the target end equipment, so that the target end equipment performs equipment upgrade based on the upgrade package; finally, when a successful restart notification sent by the target terminal equipment is detected, determining that the target terminal equipment is upgraded; through based on OpenHarmony system, adopt the interconnection intercommunication of modbus protocol realization and end equipment, can realize the remote upgrading of opposite terminal equipment, can avoid needing the engineer to go to the equipment installation scene, can save manpower and material resources, can promote equipment upgrading efficiency.
In an optional implementation manner of this embodiment, sending the upgrade packet to the target end device may include:
acquiring a target byte corresponding to a current upgrade packet round field of each data frame in the upgrade packet, and acquiring byte content corresponding to the target byte;
judging whether the byte content corresponding to the target byte is a default initial value, if so, determining to send the upgrade package for the first time, and directly sending the upgrade package to the target terminal equipment.
Specifically, when the OpenHarmony development board sends an upgrade package, firstly, after receiving the upgrade package issued by the cloud platform, the OpenHarmony development board can search and obtain two bytes corresponding to a current upgrade package round field according to the data structure of the modbus protocol data frame, so as to serve as target bytes, and can read byte contents corresponding to the target bytes; then, if it is determined that the byte content is the default initial value of 1, it indicates that the upgrade package is currently transmitted for the first time, and at this time, it may be directly transmitted.
In another optional implementation manner of this embodiment, after directly sending the upgrade packet to the target end device, the method may further include:
if a successful restarting notification sent by the target terminal equipment is not detected within a preset time threshold, determining that the current upgrade package fails to upgrade, and acquiring a current upgrade package round value;
acquiring a total upgrade package round value corresponding to a total upgrade package round field of each data frame in the upgrade package, and judging whether the current upgrade package round value is smaller than or equal to the total upgrade package round value;
and if the current upgrade package round value is smaller than or equal to the total upgrade package round value, rewriting byte content corresponding to each target byte into the current upgrade package round value to obtain a current round upgrade package, and sending the current round upgrade package to the target terminal equipment.
Specifically, after the upgrade package is sent for the first time, if a successful restart notification fed back by the target device is not received within a preset time threshold (for example, 5 minutes, etc.), it indicates that a sending failure or an upgrade failure may occur, where a total upgrade package round value may be read from a byte corresponding to the total upgrade package round field, for example, the total upgrade package round value may be 5. Then, 1 can be added to the byte content corresponding to the target byte to be used as the current upgrade package round value, namely, the current upgrade package round value is 2; at this time, the current upgrade package round value 2 is smaller than the total upgrade package round value 5, and the upgrade package transmission can be continuously attempted.
The current upgrade package round value indicates the current time of sending the upgrade package. In this embodiment, before the upgrade package is retransmitted, the field value corresponding to the current upgrade package round field in the upgrade package may be rewritten to be always equal to the current upgrade package round value, so as to obtain the current round upgrade package; the current round of upgrade package may then be sent to the target device based on the modbus protocol to cause the target device to try again for device upgrades.
It may be appreciated that after the current round of upgrade package is sent, if a successful restart notification fed back by the target device is not received within the preset time threshold, the above process may be repeated until a successful restart notification fed back by the target device is detected, or the current round of upgrade package exceeds the total round of upgrade package, for example, 5 times of upgrade packages have been sent, and the current round of upgrade package is equal to 6, where the current round of upgrade package 6 is greater than the total round of upgrade package 5, so that sending of the upgrade package may be stopped, and prompt information of upgrade failure may be generated and sent to the target client.
Optionally, after determining whether the current upgrade package round value is less than or equal to the total upgrade package round value, the method may further include:
if the current upgrade package round value is determined to be larger than the total upgrade package round value, generating upgrade failure prompt information, and sending the upgrade failure prompt information to the target client.
In another case, the total upgrade package round value may be set to 1, i.e., failed retransmissions are not supported. At this time, after the upgrade package is sent for the first time, the current upgrade package round value is equal to 2, and the current upgrade package round value is greater than the total upgrade package round value, the OpenHarmony development board can determine that the equipment upgrade fails, and can generate upgrade failure prompt information to send to the target client. The upgrade failure prompt information may include information such as an end device identifier, a number of transmission failures, failure details, and the like.
Optionally, generating the upgrade prompt information may include:
acquiring the size and the check code of the upgrade package corresponding to the upgrade package, and generating upgrade prompt information according to the size and the check code of the upgrade package corresponding to the upgrade package;
the check code is used for enabling the target terminal equipment to check the upgrade package. The size of the upgrade package can be the size of the memory occupied by the upgrade package; the check code may be a cyclic redundancy check code.
Specifically, when generating the upgrade prompt information, the upgrade package size and the check code may be encapsulated based on the modbus protocol to generate the upgrade prompt information. Then, the OpenHarmony development board may send the upgrade prompt information to the target device, and after receiving the upgrade prompt information, the target device may decode the upgrade prompt information to obtain the upgrade package size and the check code. Further, if the target terminal device determines that the available memory is larger than the size of the upgrade package, the target terminal device can generate a response and send the response to the OpenHarmony development board, and when receiving the upgrade package sent by the OpenHarmony development board, the target terminal device can firstly use the check code to perform content check on the upgrade package, and when determining that the content check passes, the target terminal device can perform device upgrade based on the upgrade package.
