[0054] In the first embodiment, the anti-crash method includes:

[0055] Step S10, detecting whether the first chip and / or the second chip has received the synchronization request information, the synchronization request information is used to notify the receiver of the synchronization request information to initialize the pin state and the synchronization encryption factor, so as to synchronize with the sender of the synchronization request information communication;

[0056] refer to Figure 8 , the first chip is used for encryption, and the encrypted ciphertext is sent to the second chip, the second chip is used for decryption, the synchronization encryption factor is used for the encryption of the first chip and the decryption of the second chip, and the synchronization encryption factor varies with With the progress of communication between the first chip and the second chip, it constantly changes synchronously; initializes the pin status of the first chip and the second...

Abstract

The application discloses a method for preventing dead halt. The method for preventing the dead halt includes steps: detecting whether synchronization requesting information which is used to inform a receiver of the synchronization requesting information to initialize lead foot status and synchronize encryption factors so as to synchronize the receiver of the synchronization requesting information with a sender of the synchronization requesting information is received by a first chip and / or a second chip; if the synchronization requesting information is received by the first chip and / or the second chip, controlling initialization of the first chip and the second chip. The invention further discloses a laser bar code scanning platform. The method for preventing the dead halt and the laser bar code scanning platform use a small number of chip resources, intelligently solve the problem that the laser bar code scanning platform halts on the premise of not needing to restart the laser bar code scanning platform, and thereby save time of restarting the laser bar code scanning platform when the laser bar code scanning platform halts, reduce time cost of users, and simultaneously improve continuity and experience feeling degrees of using the laser bar code scanning platform for users.

Description

technical field [0001] The invention relates to the technical field of barcode scanning, in particular to a crash prevention method and a laser barcode scanning platform. Background technique [0002] At present, many laser barcode scanning platforms are prone to crashes in special environments (for example, high temperature environments) or in a working state for a long time. Crashes are divided into hard crashes (that is, crashes caused by hardware failures) and soft crashes (that is, crashes caused by internal problems in software programs). [0003] According to market research, there are very few crashes caused by hardware, and most of the crashes are caused by software problems. When the laser barcode scanning platform is in a dead state, the scanning platform will not work normally. At this time, the solution of most laser barcode scanning platform manufacturers is to require users to unplug the power and then power on the laser barcode scanning platform again, so t...
