[0019] Figure 3 It is a flowchart of a method for online upgrade of a field device based on Beidou communication technology provided by an embodiment of the present invention. Detailed Embodiments

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] Since the Beidou satellites have achieved global coverage including remote areas such as the border line and uninhabited islands and reefs, the online upgrade of field devices can be realized through the Beidou satellite short message communication, making the upgrade and maintenance of the devices convenient and fast, not restricted by the field environmental conditions, and enabling the efficient operation of field devices.

[0022] The specific implementation of the above concept is described below.

[0023] Please refer to Figure 1 , an online upgrade method for field devices based on Beidou communication technology provided by an embodiment of the present invention, the method includes:

[0024] Step 100: The device management backend uses Beidou satellites to communicate with field devices for upgrade;

[0025] Step 102: After determining the upgrade, the device management backend sends the upgrade package to the field device through Beidou satellites for online upgrade of the field device.

[0026] In the embodiment of the present invention, based on the principle of Beidou short message communication, the upgrade package of the device is transmitted to the field device to be upgraded, so as to realize the upgrade and maintenance of devices in field environments such as border defense, greatly improving the maintainability and dynamic adjustment ability of field devices, solving the problem of untimely upgrade and maintenance of devices in field environments, and reducing the upgrade and maintenance costs.

[0027] The following describes Figure 1 the execution manner of each step shown.

[0028] Regarding Step 100:

[0029] Reference can be made to Figure 2 , in some embodiments, a Beidou terminal is set up in the field, and each field device is connected to the Beidou terminal; the device management backend is connected to the Beidou command terminal, so that the device management backend communicates with the Beidou terminal through the Beidou command terminal for communication and upgrade of field devices; the Beidou command terminal and the Beidou terminal communicate using the Beidou satellite channel.

[0030] In some embodiments, the Beidou terminal is connected to the field device through an RS422 or RS232 serial port, and the device management backend is connected to the Beidou command terminal through an RS422 or RS232 serial port.

[0031] Compared with wireless connection, the serial port connection is more reliable. In the wild where the signal is poor, wireless connection is prone to network disconnection or latency, which is not conducive to upgrading. The Beidou terminal is connected to the field device through the RS422 or RS232 serial port. Once connected, it is less likely to require repeated maintenance and setting, and has high reliability. The device management backend is connected to the Beidou command terminal through the RS422 or RS232 serial port. When upgrading the field device is needed, the device management backend can be connected to the Beidou command terminal through the serial port. Compared with wireless connection, it is more time-saving and convenient.

[0032] It can be referred to Figure 3 , in some embodiments, the device management backend uses the Beidou satellite to perform upgrade communication with the field device, including:

[0033] The device management backend obtains the ID of the field device to be upgraded, and uses the Beidou command terminal to send a short message carrying the upgrade username and password to the field device;

[0034] The field device receives the short message through the Beidou terminal, verifies the upgrade username and password therein, and returns an upgrade authorization code through the Beidou terminal after passing the verification.

[0035] In this embodiment, in the device management backend, the field device to be upgraded is selected. If it is determined that the device is online, the upgrade username and password of the field device to be upgraded are filled in and uploaded to the Beidou command terminal; after successful upload, the Beidou command terminal sends a short message carrying the upgrade username and password to the field device;

[0036] The field device to be upgraded receives the short message through the Beidou terminal, verifies the upgrade username and password, and returns an upgrade authorization code to the device management backend through the Beidou terminal after passing the verification; if the verification fails, it returns verification failure and ends the process.

[0037] Regarding step 102:

[0038] In some embodiments, the device management backend sends the upgrade package to the field device through the Beidou satellite for online upgrade of the field device, including:

[0039] In the device management backend, the upgrade package is selected, and it is judged whether to slice based on the size of the upgrade package, and then uploaded to the Beidou command terminal together with the upgrade authorization code, so as to send the upgrade package to the field device through the Beidou satellite;

[0040] The field device receives the upgrade package carrying the upgrade authorization code through the Beidou terminal and performs loading and upgrading according to the type of the upgrade package.

[0041] In this embodiment, the device management backend receives the authorization code from the field device to be upgraded via the Beidou command terminal; select the algorithm program or firmware program of the version to be upgraded in the device management backend, calculate the size, and if it is greater than 14000 Bit, slice it into several slices with a single packet not greater than 14000 Bit according to the package size, and each slice contains the authorization code, and upload the slices to the Beidou command terminal. If a failure feedback is received or no feedback is received after timeout, retransmit. Determine whether the uploaded slice is the last slice. If it is the last slice, wait for the upgrade result feedback. If the upgrade is successful, end the process.

[0042] The field device to be upgraded receives the sliced data with the authorization code. If the last slice data is received, integrate and restore the received complete binary upgrade package data. If the integration is successful, perform the loading and upgrade according to the upgrade package type. When the continuous failure is greater than 5 times, directly return the upgrade failure result.

[0043] In some embodiments, performing the loading and upgrade according to the upgrade package type includes:

[0044] When the upgrade package type is an algorithm program, load it into the memory of the field device to perform the upgrade;

[0045] When the upgrade package type is firmware, write the upgrade package to the Flash and restart the loading to perform the upgrade.

[0046] Please refer to Figure 2 , this embodiment of the present invention provides a field device online upgrade system based on the steps of any method embodiment in the specification. The system includes: a field device and a device management backend for managing the field device;

[0047] The device management backend uses Beidou satellites to communicate with the field device for upgrade;
