As shown in fig. 1, the control method of the display screen includes:
step S101, when a display screen of the equipment enters a screen saver interface, acquiring interaction information input by a target interaction object during last interaction recorded in an interaction record;
in the embodiment of the invention, when a user does not use the display screen for a period of time, the display screen can automatically enter the screen saver interface, the screen saver display information which is defined in advance can be displayed in the screen saver interface, the screen saver display information can refer to time information, temperature information and the like, the setting can be carried out according to actual needs, the screen saver interface does not display information contents except the screen saver display information which is defined in advance, and the energy consumption required by equipment for obtaining the information except the screen saver display information is reduced.

Step S102, acquiring acquisition information output by an information acquisition device corresponding to the interactive information;
in the embodiment of the invention, the information acquisition device can be a temperature sensor and the like, in order to detect the environment temperature condition, the temperature sensor (such as a thermistor) can be arranged at the structural position with the minimum influence of the internal temperature of the equipment, such as between the inner wall of the left side or the right side of a first-layer refrigerating chamber of a refrigerator and the outer shell, or between the inner wall of the left side or the right side of an air inlet of an internal machine of a cabinet machine and the outer shell, and between the inner wall of the bottom of an external machine fan and the outer shell, and the like, if the influence of the internal temperature of the equipment is larger, the surface of the inner wall is sprayed with a temperature insulation material, and a reticular shell with a small hemisphere protruding from the area is designed. The information acquisition device can be connected to a UART1 interface of the large-screen mainboard through a serial port line, and accordingly, when acquiring acquisition information output by the information acquisition device, the voltage value of a thermosensitive sensor for measuring the ambient temperature can be read through the UART 1.
In order to detect the temperature condition inside the device, temperature sensors may be respectively disposed in corresponding functional areas inside the device, for example, a freezing chamber and a refrigerating chamber of a refrigerator are respectively provided with one temperature sensor, then a main control board of the device is connected to a UART2 interface of a large-screen main board by using a serial port line, a hardware connection is established for software to read data of various thermal sensors of the main control board and a state of a compressor, and correspondingly, when acquiring the acquisition information output by the information acquisition device, a voltage value of the thermal sensor for measuring the temperature inside the device and the state of the compressor may be read through a UART 2.
The data of the various heat sensitive sensors and the state of the compressor are as follows:
A. reading the voltage value of an embedded thermosensitive sensor of a refrigerating chamber/temperature-changing chamber/freezing chamber of the refrigerator;
B. reading the voltage value of the air outlet/inner machine pipeline/outer machine pipeline thermosensitive sensor of the cabinet machine;
C. the ambient temperature can also be read if the inner/outer ring temperature sensor of the device is less affected internally.

In practical application, after interacting with the device, a user may need to observe whether the device operates according to the control of the interaction information, so in the embodiment of the present invention, the corresponding relationship between the interaction information and the information acquisition device may be established in advance.
For example: if the interactive information is used for controlling the temperature rise or the temperature fall in the space where the intelligent cabinet machine is located, the information acquisition devices corresponding to the interactive information are temperature sensors arranged at the air inlet and the air outlet of the intelligent cabinet machine;
if the interactive information is used for detecting whether the internal temperature of the intelligent cabinet is abnormal or not, the information acquisition device corresponding to the interactive information is a temperature sensor arranged on an internal machine pipeline/an external machine pipeline;
for another example: if the interactive information is used for controlling the increase or decrease of the output temperature of the refrigerating chamber of the refrigerator, the information acquisition device corresponding to the interactive information is a temperature sensor arranged in the refrigerating chamber of the refrigerator;
if the interactive information is information for controlling the increase or decrease of the output temperature of the freezing chamber of the refrigerator, the information acquisition device corresponding to the interactive information is a temperature sensor and the like arranged in the freezing chamber of the refrigerator.
And S103, displaying the acquired information on a screen saver interface by a display screen of the control equipment.
The read voltage value may be converted into a temperature value based on the resistance-voltage-temperature correspondence relationship.
The resistance-voltage-temperature correspondence is as follows:
A. the thermal sensor is used for reducing the resistance according to a corresponding rule when sensing that the temperature rises, so that the voltage is reduced;
B. the thermal sensor is used for increasing the resistance according to a corresponding rule when sensing that the temperature is reduced, so that the voltage is increased;
C. the different types of thermal sensors have different resistance variation amplitudes.
For example, in an ambient temperature of 25 ℃, the resistance value of a thermal sensor: 2.005k Ω, voltage value: 901 mV;
when the temperature rises to 26 ℃, the resistance value becomes: 1.919k Ω, the voltage value becomes: 881 mV;
when the temperature is reduced to 24 ℃, the resistance value becomes: 2.094k Ω, the voltage value becomes: 921 mV.
In the embodiment of the present invention, the content displayed on the display screen may include collected information, and may also include other predefined information, so that the user can know the operation condition of the device, for example: on the screen saver interface, the current time/indoor temperature/outdoor temperature/device related status is displayed.

step 301, determining whether a trigger operation is detected on an interactive key of a device;
in the embodiment of the invention, a control panel of the equipment can be provided with a plurality of preset interactive keys so as to facilitate the user to input interactive information.
When the user presses any key, it may be determined that an interactive object is detected around the device.
For example, during the operation of the device, it may be detected whether a trigger operation is detected on an interactive key on a control panel of the device, and if the trigger operation is detected, it is determined that an interactive object exists around the device, otherwise, the interactive object does not exist around the device.
Step 302, if a trigger operation is detected on an interactive key of the equipment, determining that an interactive object interacted with the equipment exists around the equipment, and determining an interactive object matched with object information of the interactive object in the interactive record as a target interactive object;
