Abstract

The invention discloses a method and device for program upgrading, and a controller. The method comprises the steps that a controller reads a verification document stored in a mobile storage device, and unit identification information and a bin document verification code are obtained, wherein the unit identification information and the bin document verification code are stored in the verification document; the controller matches the read unit identification information with identification information of the controller; when matching is successful, the controller copy an update document stored in the mobile storage device in a code cache area; the controller computes a verification code of the code cache area according to the update document written into the code cache area; and the controller uses the update document to achieve updating when the verification code of the code cache area is matched with the bin document verification code. According to the invention, the technical problem in the prior art that wrong document updating can take place easily in application of a USB-based program updating method can be solved.

Description

technical field [0001] The invention relates to the field of software, in particular to a program upgrading method and device, and a controller. Background technique [0002] When software developers write software, due to incomplete consideration or incomplete program functions, after the software is released, they release it in the form of patches after modifying the program or adding new functions. The program upgrade is to better meet the needs of users and prevent the invasion of viruses. By updating or modifying the previous software, it can ensure that users can use it safely and conveniently. [0003] There are many ways to upgrade the program, such as remote upgrade, serial port upgrade, USB upgrade, etc. [0004] The inventor found that there are defects in the above program upgrade methods: [0005] Remote upgrade requires network link support and host computer operation, the speed is relatively slow, and is greatly affected by communication quality, which is no...
