Abstract
The utility model discloses an automatic temperature adjusting system of a main control platform. The automatic temperature adjusting system comprises at least a temperature sensor arranged in the main control platform. The temperature sensor is connected with a D/A conversion circuit, an output end of the D/A conversion circuit is connected with a temperature detection circuit, and an output end of the temperature detection circuit is connected with a fan through a drive circuit. By adopting the technical scheme, an automatic temperature adjusting system is mounted on the main control platform, when temperature in the main control platform reaches a set value, a temperature digital displayer starts a strong cooling fan, and hot air in the main control platform is discharged, thereby accelerating air circulation in the main control platform, lowering work environment temperature of a rear bench machine, and preventing the rear bench from dying.
Description
Technical field
The utility model belongs to a kind of control system, specifically relates to a kind of automatic adjustment temperature controlling system.
Background technology
The phenomenon that crashes usually appears in the master station of electric system, finds by Monitoring Data, and the master station internal temperature often surpasses the rated temperature of background computer, causes the background computer operating ambient temperature too high, thereby causes background computer to crash.
Summary of the invention
The purpose of this utility model provides and a kind ofly can reduce the master station temperature, prevents the master station automatic temperature control system that background computer crashes.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises at least one temperature sensor that is positioned at master station inside, above-mentioned temperature sensor is connected with the D/A change-over circuit, the output terminal of D/A change-over circuit connects temperature sensing circuit, and the output terminal of temperature sensing circuit links to each other with fan by driving circuit.
The LM393 comparer is set in the above-mentioned temperature sensing circuit.
Above-mentioned temperature sensor is connected with display device.
Above-mentioned display device is the temperature digital display instrument.
Adopt the utility model of technique scheme, one cover automatic temperature control system has been installed on master station, like this when the master station internal temperature reaches setting value, the temperature digital display instrument will start strong thermantidote, master station internal heat air is discharged, thereby accelerate the circulation of master station inner air, reduce the background computer operating ambient temperature, the generation of having stopped background computer deadlock phenomenon.
Description of drawings
Fig. 1 is a theory diagram of the present utility model;
Fig. 2 is the circuit diagram of temperature sensing circuit and driving circuit in the utility model.
Embodiment
As shown in Figure 1, the utility model comprises at least one temperature sensor that is positioned at master station inside, temperature sensor is connected with the D/A change-over circuit, and the output terminal of D/A change-over circuit connects temperature sensing circuit, and the output terminal of temperature sensing circuit links to each other with fan by driving circuit.For showing the master station temperature inside in real time, temperature sensor is connected with display device, and display device adopts the temperature digital display instrument to show more directly perceived.
As shown in Figure 2, adopt LM393 comparer A1 that detected temperature value and preset threshold are compared in the temperature sensing circuit.Wherein, Ur is a pre-set threshold, and Ui is through the output valve behind the D/A change-over circuit, when Ui＞Ur, LM393 comparer A1 exports noble potential, makes triode T1 conducting, triode T1 collector output Uo, output terminal Uo connects the motor of fan, thereby fan is started working.
