Embodiment 1

[0038] This embodiment provides a remote online upgrade method for a data acquisition and transmission instrument terminal, such as figure 1 As shown, the method includes the following steps:

[0039] S101. The server sends an upgrade command to the terminal of the data acquisition and transmission instrument;

[0040] S102. If the terminal of the data acquisition and transmission instrument determines that the upgrade command contains new version information, then answer the server, and the terminal of the data acquisition and transmission instrument downloads the upgrade code file data, and sets the upgrade flag;

[0041] S103. If the terminal of the data acquisition and transmission instrument determines that the upgrade command does not include new version information, send a notification message that no upgrade is required to the server;

[0042] S104, the terminal of the data acquisition and transmission instrument after downloading the upgrade code file data is soft-st...

Embodiment 2

[0049] This embodiment provides a remote online upgrade method for a data acquisition and transmission instrument terminal, such as figure 2 As shown, on the basis of Embodiment 1, the method also includes the following steps:

[0050] S100. The server splits the upgrade code file data into several fixed-length data units, and forms a data packet with each data unit as a core.

[0051] In this embodiment, the server splits the upgrade code file data into multiple data units of fixed length, and forms a data packet with each data unit as the core. The frame is transmitted to the upgrade code file data in the form of the above data packet, and the total number of packets and the current packet are displayed in real time. The current packet is the data packet number currently requested by the terminal of the data acquisition and transmission instrument. This information is used to view the upgrade progress. The maintenance personnel can judge that the upgrade is successful when...

Embodiment 3

[0053] This embodiment provides a remote online upgrade method for data acquisition and transmission instrument terminals. On the basis of Embodiment 1, the upgrade command content includes: server IP address, port number, upgrade code file name, version information and total sent data number of packages.

[0054] In this embodiment, the terminal of the data acquisition and transmission instrument can judge whether to enter the upgrade state according to the version information in the content of the upgrade command. upgrade, the terminal of the data acquisition and transmission instrument will continue to run the current user application program.

Abstract

The invention is applicable to the technical field of software upgrading, and provides a remote on-line upgrading method and a system of a data acquisition and transmission instrument terminal. The method comprises the following steps: a server sends an upgrading command to the data acquisition and transmission instrument terminal; the server sends an upgrading command to the data acquisition andtransmission instrument terminal; the data acquisition and transmission instrument terminal judges whether the upgrade command contains the new version information; if yes, the answer server downloadsthe upgrade code file data and sets the upgrade flag bit by the data acquisition and transmission instrument terminal; otherwise, a notification message without upgrading is sent to the server; afterdownloading the upgrade code file data, the terminal of the data acquisition and transmission instrument softly starts, runs the bootloader program, reads the flag bit, and if the upgrade flag bit isread, the upgrade code file data is overwritten with the low version code file data, otherwise, the original user application program is executed. The invention solves the problem that the terminal of the data acquisition and transmission instrument cannot be upgraded remotely and online, and although the terminal is in the upgrading mode, the normal operation of the data acquisition and transmission instrument terminal is not affected.

Description

technical field [0001] The invention belongs to the technical field of software upgrading, and in particular relates to a remote online upgrading method and system for a data acquisition and transmission instrument terminal. Background technique [0002] The wireless data acquisition and transmission system for environmental protection monitoring is designed for online monitoring of various pollution sources, and the wireless data acquisition instrument as a terminal is mainly to obtain the data of various monitoring instruments on site, upload and save the original data, so the equipment is often installed in remote Flue gas plants, power plants and sewage treatment plants. In the actual work process, there will be two practical difficulties. One is that some functions of the user need to be modified during use, and the other is that the program itself has problems and cannot work normally. To solve such problems, the traditional method can choose the staff to go to the sit...
