This push-to-talk intelligent air conditioner remote control is easy to use and is especially suitable for the elderly and children, especially for the blind.

Background technique

With the progress of society and the development of the economy, people's living standards have been continuously improved, and air conditioners have entered the homes of ordinary people. For ease of use, air conditioners are generally controlled by an air conditioner remote control. The air conditioner remote control usually consists of four parts: function button, central processing unit (CPU), infrared emission module, and liquid crystal screen (see Figure 1). The remote control is equipped with various function buttons, such as power switch, working mode (cooling, heating, dehumidification, ventilation, automatic), temperature +, temperature -, air volume, automatic wind direction, manual wind direction, clock adjustment, time switch, Negative ions, auxiliary electric heating, etc. When a function button is pressed, the central processing unit CPU will issue a corresponding command to transmit it through the infrared transmitting module to direct the air conditioner to work. The LCD screen displays the current working status of the remote control for the user to grasp the situation at any time.

When using the air conditioner, generally press the "power switch" button on the remote control to turn on the air conditioner, then press the "operating mode" button to select the working mode (such as cooling or heating) according to the seasonal temperature, and then according to the individual. You need to press the "Temperature +,, or "Temperature -" button to set the temperature to the desired value, then press the "Air Volume" button to adjust the "large, medium, small" or "strong, weak, micro" of the air volume. You need to press the "wind direction" button to select "automatic wind direction" or "manual wind direction", etc. For the elderly, children and people with low cultural level, it is more troublesome to use, especially the characters and LCD of the function keys on the air conditioner remote control. The characters on the screen are not easy to see, and it is more difficult for presbyopia and myopia patients to use. For blind people, it is simply impossible to use. Therefore, how to overcome the defects of the above-mentioned ordinary air conditioner remote control, so that people of different ages and cultures can It is convenient to use, especially how to enable blind people to use, which is the problem to be solved by the present invention.

In order to achieve the above object, the first technical solution adopted by the present invention is: A control method of a push-to-talk smart air conditioner remote controller, the innovation thereof is: setting a temperature sensor and a smart button, using the The temperature sensor detects the ambient temperature and obtains a detection electrical signal corresponding to the ambient temperature. The detected electrical signal is input to the CPU through A/D conversion to obtain a digital ambient temperature value; a heating temperature setting value is defined in advance by software. And a cooling temperature setting value, the heating temperature setting value is smaller than the cooling temperature setting value at the value '; when the operator presses the smart button, the software program determines the ambient temperature value by the CPU The relationship between the thermal temperature set value and the cooling temperature set value. If the ambient temperature value is less than or equal to the heating temperature set value, the CPU simultaneously issues the start-up, heating, air volume control, and wind direction control commands; if the ambient temperature value If the temperature is greater than or equal to the set value of the cooling temperature, the CPU simultaneously issues the power on, cooling, air volume control and wind direction control commands; if the ambient temperature value is between the heating temperature set value and the cooling temperature set value, the CPU simultaneously issues the power on. , ventilation, air volume control and wind direction control commands, or the CPU simultaneously issues power-on, dehumidification, air volume control and wind direction control commands The instructions issued by the CPU are finally sent out by the infrared transmitting module.

In order to achieve the above object, the second technical solution adopted by the present invention is: A control method of a push-to-talk smart air conditioner remote controller, the innovation thereof is: setting a temperature sensor and a smart button, and using the temperature sensor to detect the ambient temperature, Obtaining a detection electrical signal corresponding to the ambient temperature, and inputting the detected electrical signal to the CPU through A/D conversion to obtain a digital ambient temperature value; using software to define a temperature setting value in advance; when the operator presses the intelligent When the button is pressed, the software program determines the relationship between the ambient temperature value and the temperature set value through the CPU. If the ambient temperature value is less than or equal to the temperature set value, the CPU simultaneously issues power-on, heating, air volume control, and wind direction control. If the ambient temperature value is greater than the temperature set value, the CPU simultaneously issues the power on, cooling, air volume control and wind direction control commands; the command issued by the CPU is finally sent through the infrared transmitting module.

The relevant content of the above two technical solutions is explained as follows:

1. In the above two schemes, the air volume control command may be set to a medium air volume or a large air volume or a small air volume by software in advance. The wind direction control command may be set to an automatic wind direction or a manual wind direction by software in advance.

2. In the above two schemes, in order to use the smart button to shut down, the smart button can be pressed again by software to issue a shutdown command. When the air conditioner is turned on, press the smart button again. The CPU issues a shutdown command to shut down the air conditioner.

3. The above two schemes can be used to independently manufacture an air conditioner remote controller, or can be combined with an existing air conditioner remote controller to manufacture an air conditioner remote controller, wherein each function button of the existing air conditioner remote controller can be completely or partially retained, and the present invention The smart buttons do not affect the function buttons of the existing air conditioner remote control. The method of the invention is applicable to a single type (a type of air conditioner model matched with an air conditioner remote controller), a universal type (universal type) and a comprehensive type (multi-function remote controller for air conditioner, color TV, DVD remote control) and the like. air-conditioner remote. 4. In the above two schemes, in order to distinguish the smart button from other function buttons, the smart button can use different colors or logos, and different colors such as red or green can be different from other function button colors.

In the present invention, the smart button can be clicked, and the LCD screen is not required to be viewed, so that it is easy and labor-saving.

3. The status characters displayed on the LCD screen of the existing air conditioner remote control are words or patterns, and the elderly, children, and people with low cultural level are not easy to recognize. However, the present invention only needs to press the smart button, and does not need to understand the characters on the LCD screen, so it is suitable for both young and old, and people with low cultural level can operate freely.

4. The function buttons and LCD screens on the existing air conditioner remote control are represented by words or patterns. Operators with poor eyesight such as presbyopia and myopia may not be able to see if they are not wearing glasses. It is very inconvenient to use.

The ventilation or dehumidification command issued by the CPU can be defined by software according to the user's needs. Dehumidification is generally applicable to the south, especially in the southern Meiyu season, and the ventilation is generally applicable to the north or the south. The air volume control command may be set to a medium air volume or a large air volume or a small air volume by software in advance, wherein the medium air volume is preferred. The wind direction control command can be set to automatic wind direction or manual wind direction by software in advance, wherein the automatic wind direction is better. The selection of the heating temperature setting value and the cooling temperature setting value can be flexibly determined in consideration of the comfort of the general human body and the national energy saving regulations, in addition to the examples of the present embodiment.

In this embodiment, the temperature sensor can use a thermistor, and the ambient temperature detecting circuit can have the following two forms:

(1) voltage dividing circuit

As shown in FIG. 5, the ambient temperature detecting circuit is composed of a voltage dividing circuit formed by a series connection of a fixed reference resistor R1 and a thermistor R2, and the power supply VDD forms a loop through the voltage dividing circuit to the ground, from the fixed reference resistor R1 and the heat. The voltage dividing point between the varistor R2 leads to the output terminal 0, and the voltage signal outputted by the output terminal O changes with the change of the ambient temperature, and the voltage signal serves as a detection signal of the ambient temperature. Since the voltage of the power supply VDD, the voltage of the output terminal O, and the resistance value of the fixed reference resistor R1 are known, the resistance voltage circuit formula can calculate the resistance value of the thermistor R2, and then the environment can be obtained according to the characteristics of the thermistor R2. Temperature value.

(2) charge and discharge circuit

As shown in FIG. 6, the ambient temperature detecting circuit is composed of a fixed reference resistor R1, a capacitor C1 and a thermistor R2. One end of the fixed reference resistor R1, one end of the thermistor R2 and one end of the capacitor C1 are connected in parallel. The other end of C1 is grounded, the other end of the fixed reference resistor R1 serves as the first input/output terminal I/O1, and the other end of the thermistor R2 serves as the second input/output terminal 1/02. The fixed reference resistor R1 and the capacitor C1 constitute a first charge and discharge circuit, and the thermistor R2 and the capacitor C1 constitute a second charge and discharge circuit. As shown in FIG. 7, when the first input/output terminal I/O1 is at a high level, the first charging and discharging circuit charges the capacitor C1, and the voltage output from the second input/output terminal I/02 can detect the first pair of capacitors. C1 charging time T1; then when the first input/output terminal I/O1 and the second input/output terminal I/02 are both low level, discharging the capacitor C1; as shown in FIG. 8, when the second input/output terminal I When /02 is high, the second charging and discharging circuit charges the capacitor C1, and the voltage output from the first input/output terminal I/O1 can detect the charging time T2 of the capacitor C1 for the second time. Using the formula: T1/T2 = R1/ R2, can The resistance value of the thermistor R2 is calculated, and the ambient temperature value can be obtained according to the characteristics of the thermistor R2.

In this embodiment, in order to distinguish the smart button from other function buttons, different colors, such as red or green, may be used, which is different from other function button colors. In order to facilitate the use of blind people, the smart button can be used to set Braille or concave and convex hand signs. For example, the obvious touch sign of the pit or bump is designed on the top surface of the smart button to distinguish it from other function buttons for the blind person to recognize.

The method of the embodiment can be independently applied to the air conditioner remote controller, or the control method can be added on the basis of the existing air conditioner remote controller, so that all the function keys of the existing air conditioner remote controller are retained in whole or in part. The heating temperature set value and the cooling temperature set value can be selected according to the user's needs during product design. Once the user is defined by the software, the user cannot change it. If the user feels that the set temperature is not ideal during use, he can wait until the machine is turned on. For example, in the embodiment, when the ambient temperature is less than or equal to 18 °C, the CPU simultaneously issues the power-on, heating, medium air volume and automatic wind direction commands, if the user feels If the temperature is too high or too low, wait for the air conditioner to work. Press the "Temperature +" or "Temperature -" function button on the remote control to adjust the temperature you want. The specific temperature value can be on the LCD screen of the remote control. Similarly, when the air conditioner is cooling, if the user feels that the temperature is too high or too low, after the air conditioner is working, press the "Temperature +" or "Temperature -" function button on the remote control to adjust itself. The required temperature. For the convenience of operation, the "temperature +" or "temperature -" two function buttons can be designed next to the smart buttons for user convenience.

Embodiment 2: Control method of push-to-talk intelligent air conditioner remote controller

When the operator presses the smart button, the software program determines the relationship between the ambient temperature value and the temperature setting value through the CPU, if the ambient temperature value is less than or equal to the temperature. When the set value is set, the CPU simultaneously issues power-on, heating, air volume control and wind direction control commands. If the ambient temperature value is greater than the temperature set value, the CPU simultaneously issues power-on, cooling, air volume control and wind direction control commands.

When the air conditioner is turned on, the smart button is pressed again. The CPU issues a shutdown command to shut down the air conditioner.

The main difference between this embodiment and the first embodiment is that the two different temperature setting values of the heating temperature setting value and the cooling temperature setting value of the first embodiment are changed to one temperature setting value, from FIG. 3 and FIG. As can be seen from the comparison in Fig. 4, the first embodiment consists of three different temperature set values on the lateral coordinate to form a three-stage temperature interval, and the second embodiment forms a two-stage temperature on the lateral coordinate by a temperature set value. Interval. This embodiment A temperature setting value, as shown in Figure 4, can be defined as a value corresponding to 25 °C. When the operator presses the smart button, if the ambient temperature is less than or equal to 25 °C, the CPU simultaneously issues the power-on, heating, air volume control and wind direction control commands; if the ambient temperature is greater than 25 °C, the CPU simultaneously turns on the power and cools , air volume control and wind direction control commands. The air volume control command may be set to a medium air volume or a large air volume or a small air volume by software in advance, wherein the medium air volume is preferred. The wind direction control command can be set to automatic wind direction or manual wind direction by software in advance, wherein the automatic wind direction is better. The selection of the temperature setting value can be flexibly determined in consideration of the comfort of the general human body and the national energy saving regulations, in addition to the examples of the present embodiment. Although only one temperature setting value is designed in the method of the embodiment, for ordinary users, air conditioning is generally not used in spring and autumn, and when air conditioning is used in winter and summer, the ambient temperature is large, such as the ambient temperature in winter. At 2 ° C, the summer ambient temperature is 35 ° C, always make the right choice.
