Man-machine interaction multistage password setting method

Abstract

The invention discloses a man-machine interaction multi-level password setting method. The method comprises the steps that man-machine interaction protection is preset into a plurality of levels, level parameters and interface parameters through man-machine interaction upper configuration; an interactive touch screen acquires the interface parameters and displays an equipment interface according to the interface parameters; wherein the man-machine interaction upper configuration is in communication connection with a plurality of pieces of sub-equipment and acquires interaction time informationand state information of the plurality of pieces of sub-equipment in real time; if the interaction time is greater than the current level protection time, the man-machine interaction upper configuration sends a locking instruction to control the interaction touch screen to execute a locking operation so as to lock the interaction touch screen; through inputting an unlocking instruction or a time-delay instruction, unlocking or time-delay interaction locking protection is realized. According to the man-machine interaction multistage password setting method provided by the invention, multiple stages of interaction protection, delay interaction protection and multiple unlocking modes can be set, so that delay man-machine interaction protection is dynamically realized before the interaction protection is executed.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a method for setting a multi-level password for human-computer interaction. Background technique [0002] At present, with the transformation and upgrading of my country's traditional industrial technology, the rapid development of factory automation and enterprise informatization, the society's demand for industrial automation control products will continue to grow. Industrial automation control products are an important prerequisite and guarantee for achieving scale, efficiency, precision, and intelligence, and are widely used. HMI (User Human Machine Interface) is very important for the operation and maintenance of industrial automation equipment, the user interface provides the user to monitor the machine status, production status, etc. during operation. If the user does not have these interactive interfaces, the realization of industrial automation is inconvenient....

Problems solved by technology

[0003] The existing password unlocking HMI protection method is to set multi-level HMI protection unlocking passwords in the configuration program of the host computer. When the HMI application verifies that the input password is the same as the set password, the current level of HMI protection lock will be released, otherwise the HMI interface will remain locked and the user will no longer be able to operate the HMI

The existing method can only set a fixed time limit in the configuration program of the host computer in advance, and when the touch screen performs HMI protection, the user or the technical service personnel of the equipment manufacturer can unlock and release it by inputting a fixed and correct unlock password, using a fixed password There are some problems. On the one hand, the long time leads to the omission or misremembering of the password. On the other hand, the unlocking password is lost due to the replacement of the staff, which leads to the lock screen problem of the touch screen.
