Maximum input password number is input password frequency threshold value, and user need to input and default in limited input password number
The password that password matches could successfully release forced shutdown.Every forced shutdown that successfully releases is primary, and selection is released number
Increase by 1, it is therefore an objective to record the number of user's forced shutdown；And input password number is zeroed, it is therefore an objective in the process of each round
In, guarantee that the password number of the maximum input of user is all equal.
Particularly, user successfully excessively once selected release forced shutdown after, can after being spaced preset time period, then
101 are returned to step, i.e., after being spaced preset time period, starts the circulation of a new round.
Further, if user input password and preset password mismatch, and user input password number be less than or
Equal to input password frequency threshold value, then interface for password input is shown in the display equipment of industry monitoring device, it is another convenient for user
Secondary input password.
Particularly, it is greater than selection releasing threshold value when selection releases number, i.e. the selection of user releases the number of forced shutdown
It uses up；Or forced shutdown is confirmed based on selection operation, i.e. user independently selects forced shutdown；Or input password number is greater than
Preset input password frequency threshold value, i.e. user are in limited input password number, and the password of input and preset password are not
Match.In the case of these three, it will appear the case where controlling industry monitoring device forced shutdown.
In embodiments of the present invention, when temperature averages are greater than third temperature threshold, and third temperature threshold is the limit
Temperature not only shows shutdown selection interface in the display equipment of industry monitoring device, independently chooses whether to force to close convenient for user
Machine prevents in case of emergency, since the forced shutdown of industrial display causes the loss of user.If being also provided with user
Not forced shutdown is selected, then needs to input the password with preset password match, prevents third party from arbitrarily manipulating.In addition to this, also
It limits user to select to release the maximum times of forced shutdown, prevents from selecting not forced shutdown due to user, and cause industry aobvious
Show that device works for a long time in the case where limiting temperature, the service life of component is impacted.
