An over-temperature protection method and device for an industrial monitor

Abstract

The invention discloses an industrial monitor over-temperature protection method and device. Since a temperature sensor is arranged on the surface of a main board of an industrial monitor, temperatureof each component can be obtained directly in real time; the detected temperature values are taken as reference for execution protection, and are processed to obtain a temperature average value; three temperature threshold values are set in advance; when the temperature average value surpasses the first temperature threshold value, a fan in the industrial monitor is controlled to start; when thetemperature average value surpasses the second temperature threshold value and the fan is started, the brightness of a display device of the industrial monitor is controlled to reduce to a preset brightness value, and an over-temperature protection effect is allowed to be better; and when the temperature average value surpasses the third temperature threshold value, the display device in the industrial monitor displays a shutdown selection interface to allow a user to confirm whether to carry out forced shutdown, so that the user can freely select whether to carry out shutdown under an emergency state so as to make an effective choice.

Description

technical field [0001] The invention relates to the technical field of over-temperature protection, in particular to an over-temperature protection method and device for an industrial monitor. Background technique [0002] At present, for industrial-grade products such as monitors, the difference between the internal temperature and the ambient temperature mainly depends on the installation method. [0003] Set the installation method A, which has the advantage of better heat dissipation. In this installation method, when the ambient temperature is 35°C, the internal temperature may be 48°C; if the installation method B is set, the disadvantage is that the heat dissipation is not ideal. In this installation mode, when the ambient temperature is 35°C, the internal temperature may be 58°C. That is, when the value of the ambient temperature is the same, the temperature inside the machine will also have a large difference due to the difference in the installation method. Howe...
