Embodiment Construction

[0055] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0056] In medical equipment, taking CT equipment as an example, there are multiple control nodes, and each control node has its corresponding memory, or an external memory can be connected to the control node, and the memory can be flash memory (flash memory). The In Application Programming (IAP) technology can map the memory into two areas, namely the boot loader (Bootloader) area and the application (Application) area. The IAP program is stored in the Bootloader area, and the application program is stored in the Application area. . Among them, the IAP program can be burned into the CT device before leaving the factory, or it can be burned into the Bootloader area after the factory needs to use the IAP technology to upgrade, and then it can be upgraded without re-burning. The control node can read...

Abstract

The invention provides a control node online upgrading method and device, an upper computer, a system and an electronic device. The method comprises the following steps: receiving an erasure instruction, erasing an application program in an Application area according to the erasure instruction, and sending a data request to an upper computer after the erasure is completed; and receiving the upgrading data and storing the upgrading data into the Applications area so as to complete online upgrading. According to the embodiment of the invention, the memory is divided into the Bootloader region and the Applications region through the IAP technology, communication with the upper computer is realized through the IAP program, the application program is erased, and the upgrading data is written into the Applications area, so that the control node can be upgraded without detaching the shell, and the program upgrading efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of application programming, in particular, to a control node online upgrade method, device, upper computer, system and electronic equipment. Background technique [0002] With the development of medical technology, computed tomography (Computed Tomography, CT) equipment is more and more valued by hospitals and equipment manufacturers. The core control technology industry of CT equipment is becoming more and more mature, and it is often necessary to control the node program of each component Upgrade, update. Traditionally, if it is necessary to update the program for the control node, the engineer needs to go to the production site or hospital to burn the program by downloading the device. The number of nodes on the CT device bus is large and scattered. In most cases, the cover or hardware needs to be removed. circuit board, thereby reducing the efficiency of program upgrades. Contents of the inv...
