Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar modules or modules having the same or similar functionality throughout. The embodiments described below with reference 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 application include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.
Example 1
The embodiment provides a method for preventing the environmental control equipment in the electronic system from freezing, and the method can simply, conveniently and quickly avoid the phenomenon that the environmental control equipment in the electronic system freezes in a low-temperature environment.
In practical application, the method comprises the following steps:
the threshold temperature t is preset and needs to be set according to the working temperature of the electronic system in the low-power-consumption working mode, and the heat generated by the electronic system in the low-power-consumption working mode can be naturally dissipated to achieve heat balance, so that the threshold temperature t is set according to the working temperature in the low-power-consumption working mode to determine whether the in-machine environment control equipment is started to work in time.
If the environmental temperature is not lower than the threshold temperature t, the electronic system and the in-machine environmental control equipment are started to operate synchronously; specifically, whether the internal ring control equipment is started is not controlled by a high-power-consumption working mode control signal of the power subsystem but is controlled by the starting of the power subsystem, and when the power subsystem is started by power supply, the internal ring control equipment is synchronously started; otherwise, the internal ring control device is in a non-operating state, and the corresponding operating sequence is shown in fig. 3.
And if the ambient temperature is lower than the threshold temperature T, starting a high-power-consumption working mode of the electronic system as a trigger signal, and controlling the internal loop control equipment to start to operate after the delay time T2 according to the trigger signal. Specifically, the start of the internal ring control device is controlled by the control signal of the high power consumption operating mode of the power subsystem, but not by whether the power subsystem is started, when the electronic system starts the high power consumption operating mode, the internal ring control device starts to operate after a delay time T2, that is, the internal ring control device waits for a period of delay time T2 before operating, and the corresponding operating timing sequence is shown in fig. 4.
The delay time T2 is determined according to a difference between a heat value of the electronic system in the high power consumption operating mode and a heat dissipation amount of the internal environment control device, and when the difference between the heat value of the high power consumption operating mode and the heat dissipation amount of the internal environment control device is within a reasonable range, the phenomenon that the internal environment control device freezes can be avoided.
Example 2
The embodiment specifically discloses an apparatus for preventing environmental control equipment in an electronic system from freezing, an operation schematic diagram of which is shown in fig. 2, and the apparatus includes: switch and delay switch, delay switch sets temperature sensor, measures external ambient temperature through temperature sensor in order to switch this delay switch's operating condition, and here, 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 delay switch is electrically connected with the internal environment control equipment, the other end of the delay switch is electrically connected with the power switch, and when the power switch and the delay switch are both switched on, the internal environment control equipment has a starting condition. In order to avoid the phenomenon of icing of the environment-friendly equipment in the machine, the time delay switch is respectively in communication connection with the electronic system and the power switch, and the time delay switch is controlled to be started by the electronic system or the power switch according to different environmental temperatures. When the time delay switch is controlled by an electronic system to be started in actual work, the time delay switch is started to trigger the time delay switch to be switched on in a time delay mode 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 the icing of the environmental control equipment in the electronic system, the working principle is as follows:
because the in-machine environmental control equipment is connected to the power supply end through the delay switch, and the working state of the delay switch is switched according to the external environment temperature, when the environment temperature is not lower than the threshold temperature t, the action of the delay switch is synchronous with the power supply switch of the electronic system and does not have the delay function; at this moment, the external environment temperature is too high, and no matter the electronic system runs, no matter it is in low-power consumption mode, still high-power consumption mode, the electronic system can not satisfy the requirement through natural heat dissipation, consequently, when the electronic system switch on power starts, also need open in-machine environmental control equipment in step and carry out the inside refrigeration heat dissipation to satisfy the normal operating temperature demand of electronic system.
When the environmental 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. In this case, if the electronic system does not start the high power consumption operating mode (in the low power consumption operating mode), the internal ring control device does not operate, and the heat generated by the 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 internal ring control device needs to wait for a delay time T2 to operate after the electronic system starts the high-power-consumption working mode, so that the difference between the heating of the electronic system in the high-power-consumption working mode and the natural heat dissipation and the refrigerating and heat dissipation of the internal ring control device is controlled within a reasonable range, the possibility of icing of the internal ring control device is avoided, and the normal working of the electronic system and the internal ring control device is ensured.
Based on the device provided in the embodiment, in practical application, the electronic system is used in various environmental conditions such as indoor, outdoor, different seasons, different altitudes and the like, and the phenomenon of icing does not occur in the internal environment control equipment.
