Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar modules or modules having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application. On the contrary, the embodiments of the present application include all alternatives, modifications, and equivalents as may be included within the spirit and scope of the appended claims.
Example 1
The embodiment provides a method for preventing the in-machine environmental control equipment of the electronic system from icing, which can simply, conveniently and quickly avoid the phenomenon that the in-machine environmental control equipment of the electronic system is frozen in a low-temperature environment.
In practical application, the method comprises the following steps:
the threshold temperature t is preset, the threshold temperature t needs to be set according to the working temperature of the electronic system in the low-power-consumption working mode, and because the heat generated by the electronic system in the low-power-consumption working mode can reach heat balance through natural heat dissipation, the threshold temperature t is set according to the working temperature in the low-power-consumption working mode to determine whether the built-in environmental control equipment starts working in time or not.
If the ambient temperature is not lower than the threshold temperature t, the electronic system and the built-in environmental control equipment are synchronously started to operate; specifically, whether the built-in loop control equipment is started is not controlled by a high-power-consumption working mode control signal of the electronic system, but is controlled by the starting of the electronic system, and when the electronic system is started by power supply, the built-in loop control equipment is synchronously started; otherwise, the built-in environmental control equipment is in a non-working state, and the corresponding working time sequence is shown in fig. 3.
If the ambient temperature is lower than the threshold temperature T, starting the electronic system through a high-power-consumption working mode to serve as a trigger signal, and starting operation after controlling delay time T2 of the internal control equipment of the electronic system according to the trigger signal. Specifically, the startup of the in-machine environmental control equipment is controlled by the control signal of the high-power-consumption working mode of the electronic system, but not by whether the electronic system is started, when the electronic system starts the high-power-consumption working mode, the in-machine environmental control equipment starts to run after the delay time T2, namely, the in-machine environmental control equipment waits for a period of delay time T2 and then works and moves, and the corresponding working time sequence is shown in fig. 4.
The delay time T2 is determined according to a difference between a heating value of the electronic system in the high-power-consumption working mode and a heat dissipating capacity of the built-in environmental control equipment, and when the difference between the heating value of the high-power-consumption working mode and the heat dissipating capacity of the built-in environmental control equipment is within a reasonable range, the phenomenon that the built-in environmental control equipment is frozen can be avoided.
Example 2
In this embodiment, a device for preventing an in-machine environmental control device of an electronic system from icing is specifically disclosed, and a working schematic diagram of the device is shown in fig. 2, where the device includes: the power switch and the time delay switch, time delay switch has set up temperature sensor, measures external ambient temperature in order to switch this time delay switch's operating condition through temperature sensor, and here, time delay switch's operating condition means: the action of the delay switch is controlled by the signal of the electronic system or the signal of the power switch.
The power switch is electrically connected with the electronic system, the other end of the power switch is electrically connected with the power supply end, and the electronic system is connected or disconnected through the on-off of the power switch.
The time delay switch is electrically connected with the built-in loop control equipment, the other end of the time delay switch is electrically connected to the power switch, and when the power switch and the time delay switch are both on, the built-in loop control equipment has starting conditions. In order to avoid the phenomenon that the built-in environmental control equipment is frozen, the delay switch is respectively in communication connection with the electronic system and the power switch, and the delay switch is controlled to be started by the electronic system or the power switch according to different environmental temperatures. When the delay switch is controlled to be started by the electronic system in actual operation, the delay switch is started and triggered to be turned on in a delay way through a high-power-consumption mode of the electronic system; when the delay switch is controlled to be started by the power switch, the on-off of the delay switch is triggered by the on-off of the power switch, and the delay switch does not have a delay function.
Based on the device for avoiding icing of the built-in environmental control equipment of the electronic system, the working principle is as follows:
the built-in loop control equipment is connected to the power supply end through the delay switch, the working state of the delay switch is switched according to the external environment temperature, and when the environment temperature is not lower than the threshold temperature t, the action of the delay switch is synchronous with the power switch of the electronic system and has no delay function; at this time, the external environment temperature is too high, and when the electronic system is in a low-power-consumption working mode or a high-power-consumption working mode, the electronic system cannot meet the requirements through natural heat dissipation, so that when the electronic system is powered on and started, the internal environment control equipment in the machine is also required to be synchronously started for internal refrigeration and heat dissipation so as to meet the normal working temperature requirements of the electronic system.
When the ambient temperature is lower than the threshold temperature t, the action of the delay switch is synchronous with the starting of the high-power-consumption working mode of the electronic system and has a delay function. Under the condition, if the electronic system does not start a high-power-consumption working mode (in a low-power-consumption working mode), the built-in environmental control equipment does not operate, and heat generated by low power consumption can reach heat balance through natural heat dissipation; if the electronic system starts the high-power-consumption working mode, because the heat generated during the high-power-consumption working is gradually accumulated, the built-in environmental control equipment needs to wait for a delay time T2 to run after the electronic system starts the high-power-consumption working mode, so that the difference between the heating and natural heat dissipation of the electronic system in the high-power-consumption working mode and the refrigerating and heat dissipation of the built-in environmental control equipment is controlled within a reasonable range, the possibility of icing of the built-in environmental control equipment is avoided, and the normal working of the electronic system and the built-in environmental control equipment is further ensured.
