[0041] The utility model provides a temperature acquisition circuit which is applied to the intelligent remote controller. Figure 1 , Figure 1 This is a functional module diagram of an embodiment of the temperature acquisition circuit of the utility model. In this embodiment, the temperature acquisition circuit is connected to the battery B1; the temperature acquisition circuit includes a control module 100, a voltage stabilizing module 200 and a temperature acquisition module 300; the power supply end of the control module 100 is connected to the battery B1, the output end of the control module 100 is connected to the power supply end of the temperature acquisition module 300 through the voltage stabilizing module 200, and the output end of the temperature acquisition module 300 is connected to the acquisition end of the control module 100; wherein:

[0042] The control module 100 is used to output voltage to the voltage stabilizing module 200;

[0043] The voltage stabilizing module 200 is used to receive the voltage output by the control module 100, and convert the voltage output by the control module 100 into a target voltage and then output it to the temperature acquisition module 300;

[0044] The temperature acquisition module 300 is used to acquire the temperature of the battery B1 based on the target voltage output by the voltage stabilization module 200, obtain a temperature signal, and send the temperature signal to the control module 100;

[0045] The control module 100 is used to receive the temperature signal sent by the temperature acquisition module 300 and determine the operating environment temperature according to the temperature signal.

[0046] The battery B1 supplies power to the electrical devices in the intelligent remote control, including but not limited to the control module 100; the control module 100 is powered by the battery B1, and at the same time, the control module 100 outputs a voltage to the temperature acquisition module 300; it can be understood that, based on the different battery capacities, the power supply voltage of the battery B1 to the control module 100 is different, and the voltage output from the control module 100 to the temperature acquisition module 300 is also different, and the temperature signal of the temperature acquisition module 300 is affected by the voltage provided. When the voltage output from the control module 100 to the temperature acquisition module 300 is different, at the same temperature, the temperature The acquisition module 300 will output different temperature signals, resulting in inaccurate temperature detection. In order to solve this problem, a voltage stabilizing module 200 is provided in the present embodiment. The voltage output by the control module 100 is first stabilized to a target voltage by the voltage stabilizing module 200, and then output to the temperature acquisition module 300, thereby ensuring that the temperature acquisition module 300 performs temperature acquisition based on a fixed voltage, and ensuring the correlation between the operating environment temperature and the temperature signal output by the temperature acquisition module 300, so that the control module 100 can accurately determine the operating environment temperature of the battery B1 based on the temperature signal output by the temperature acquisition module 300.

[0047] The control module 100 may specifically be a control chip provided in the intelligent remote controller, or may be a control device specially provided for the temperature acquisition circuit.

[0048] The temperature detection device in the temperature acquisition module 300 is arranged in contact with the battery B1 in space, thereby realizing the detection of the operating environment temperature.

[0049] It is understandable that the specific value of the target voltage corresponding to the voltage stabilizing module 200 can be set based on actual needs. After the temperature acquisition circuit is set, the corresponding relationship between the operating environment temperature and the temperature signal output by the temperature acquisition module 300 can be determined based on the specific settings of the voltage stabilizing module 200 and the temperature acquisition module 300, and the corresponding relationship is stored in the control module 100; specifically, the temperature signal output by the temperature acquisition module 300 can be obtained at different operating environment temperatures, thereby obtaining the corresponding relationship between the operating environment temperature and the temperature signal.

[0050] This embodiment provides a voltage stabilizing module 200 so that the voltage output by the control module 100 can be converted into a target voltage and then output to the temperature acquisition module 300, thereby ensuring the power supply stability of the temperature acquisition module 300 and further ensuring the temperature acquisition accuracy of the temperature acquisition module 300.

[0051] Further, see also Figure 2 , the voltage stabilizing module 200 includes a first resistor R1 and a voltage stabilizing diode D1, wherein:

[0052] The first end of the first resistor R1 is connected to the voltage output end of the control module 100, the second end of the first resistor R1 is connected to the power supply end of the temperature acquisition module 300, the second end of the first resistor R1 is also connected to the cathode of the Zener diode D1, and the anode of the Zener diode D1 is grounded.

[0053] The first resistor R1 is used to receive the voltage output by the control module 100; it is understandable that when the voltage-stabilizing diode D1 is in a reverse breakdown state, the voltage across the two ends remains substantially unchanged, therefore, when the voltage of the control module 100 is transmitted to the cathode of the voltage-stabilizing diode D1 through the first resistor R1, the voltage-stabilizing diode D1 reversely breaks down, and the cathode voltage of the voltage-stabilizing diode D1 will remain at its stabilizing value, and the stabilizing value of the voltage-stabilizing diode D1 is the target voltage of the voltage-stabilizing module 200; the cathode of the voltage-stabilizing diode D1 is connected to the power supply end of the temperature acquisition module 300, therefore, the voltage output to the temperature acquisition module 300 is maintained at the stabilizing value of the voltage-stabilizing diode D1, thereby ensuring that the voltage input to the temperature acquisition module 300 is fixed.

[0054] The voltage stabilization value of the voltage stabilizing diode D1 can be selected based on actual needs, such as 1.2V.

[0055] It should be noted that, in actual applications, other voltage stabilizing devices can also be used to convert the voltage output by the control module 100 into a target voltage, such as a voltage stabilizing chip or other voltage stabilizing circuits. However, the operating environment temperature detection circuit in this embodiment is applied to a smart remote control. Generally, most smart remote controls use a disposable lithium battery B1. While the power supply voltage is relatively small, it is necessary to reduce power consumption as much as possible. Other voltage stabilizing chips and voltage stabilizing circuits, such as LDO, have higher voltage requirements and will consume more power. They are not convenient to be used in smart remote controls. Therefore, in this embodiment, a voltage stabilizing diode D1 is used to achieve the output of the target voltage, which is easy to implement without consuming too much power and has a low cost.

[0056] Furthermore, the temperature acquisition module 300 includes a second resistor R2 and a temperature-sensitive resistor RT, wherein:

[0057] The first end of the second resistor R2 is connected to the voltage stabilizing module 200 , the second end of the second resistor R2 is connected to the collection end of the control module 100 , and the second end of the second resistor R2 is also grounded through the temperature sensitive resistor RT.

[0058] The second resistor R2 and the temperature-sensitive resistor RT form a voltage divider circuit; after the target voltage is input into the temperature acquisition module 300, it is divided by the second resistor R2 and the temperature-sensitive resistor RT. The voltage signal obtained after the voltage division is the temperature signal, and the temperature signal is output to the acquisition end of the control module 100 through the second end of the second resistor R2.

[0059] The resistance of the thermistor RT changes with the ambient temperature, that is, the operating environment temperature. Specifically, the specific parameters of the thermistor RT can be selected based on actual needs. For example, the thermistor RT in this embodiment is NTC (Negative Temperature Coefficient), and the resistance of the thermistor RT decreases with the increase of the operating environment temperature. When the resistance of the thermistor RT decreases, the voltage of the output temperature signal becomes smaller accordingly; that is, the higher the operating environment temperature, the smaller the voltage value of the temperature signal received by the control module 100, and conversely, the lower the operating environment temperature, the larger the voltage value of the temperature signal received by the control module 100.

[0060] Furthermore, the temperature acquisition circuit further includes a filter module 400 , and the filter module 400 is connected between the temperature acquisition module 300 and an acquisition end of the control module 100 .

[0061] The voltage output by the control module 100 to the voltage stabilizing module 200 passes through its internal digital power supply circuit. Therefore, the output voltage contains digital switch ripple. After the voltage is stabilized by the voltage stabilizing module 200 and the temperature detection module performs voltage division, the generated temperature signal also contains ripple. If the temperature signal containing ripple is directly sent to the acquisition end of the control module 100, it will be interfered by the ripple. The operating environment temperature determined by the control module 100 based on the temperature signal containing ripple is not accurate enough. Therefore, in this embodiment, a filtering module 400 is set to filter out the ripple in the temperature signal, and send the temperature signal after the ripple is filtered out to the acquisition end of the control module 100, so as to improve the accuracy of determining the operating environment temperature.

[0062] Furthermore, the filtering module 400 includes a third resistor R3 and a first capacitor C1, wherein:

[0063] The first end of the third resistor R3 is connected to the temperature acquisition module 300, the second end of the third resistor R3 is grounded through the first capacitor C1, and the second end of the third resistor R3 is also connected to the acquisition end of the control module 100;

[0064] The filtering module 400 is used to filter out the ripple of the temperature signal and then send the temperature signal to the control module 100 .

[0065] The third resistor R3 and the first capacitor C1 form an RC filter, and the ripple in the temperature signal can be effectively filtered out by the RC filter.

[0066] Further, the control module 100 includes a control unit and a voltage output unit, the power supply end of the control unit serves as the power supply end of the control module 100, the acquisition end of the control unit serves as the acquisition end of the control module 100, the output end of the control unit is connected to the control end of the voltage output unit, and the output end of the voltage output unit serves as the output end of the control module 100; wherein:

[0067] The control unit is used to send an output signal to the voltage output unit when a temperature detection condition is triggered;

[0068] The voltage output unit is used to output voltage to the voltage stabilizing module 200 when receiving the output signal.

[0069] It is understandable that when performing temperature detection, the control module 100 needs to output voltage to the temperature detection module; if the temperature detection state is maintained continuously, the battery B1 needs to bear the additional power required for temperature detection, which increases the consumption of the battery B1 and reduces the service life of the battery B1; especially when the battery B1 of the smart remote control adopts a disposable battery B1, it is more necessary to consider the extension of the service life of the battery B1; therefore, in this embodiment, a temperature detection condition is set, and only when the temperature detection condition is triggered, the voltage output unit is controlled to output voltage to the voltage stabilizing module 200, and when the temperature detection condition is not triggered, the output voltage of the voltage stabilizing module 200 is stopped, thereby avoiding excessive consumption of battery power due to temperature detection.

[0070] It should be noted that the control unit and the voltage output unit in this embodiment can be two independently arranged units, or they can be integrated in a single device that can realize the above functions. For example, the control module 100 is a microcontroller, the power supply end of the microcontroller is connected to the battery B1, the GPIO end of the microcontroller is connected to the voltage stabilizing module 200 as the output end, and the AD_IN end of the microcontroller is connected to the filtering module 400 as the acquisition end; and the microcontroller integrates the control function and the voltage output function. In this case, the microcontroller internally realizes the output of the output signal based on the temperature detection condition, thereby realizing the functions of the above control unit and the voltage output unit.

[0071] The temperature detection conditions can be set based on actual needs, such as setting a temperature detection time threshold in the control unit, starting the timing after the system is started or the last temperature detection is completed, and if the timing time reaches the temperature detection time threshold, the voltage output unit is controlled to output voltage to the voltage stabilizing module 200. After the control unit receives the temperature signal, the voltage output unit is controlled to stop outputting voltage to the voltage stabilizing module 200, and this temperature detection is completed;

[0072] For another example, a power trigger threshold is set, and the remaining power of the battery B1 is detected by the control unit. When the remaining power of the battery B1 is lower than the power trigger threshold, the temperature detection condition is met, and the voltage output unit is controlled to output voltage to the voltage stabilizing module 200. After the control unit receives the temperature signal, the voltage output unit is controlled to stop outputting voltage to the voltage stabilizing module 200.

[0073] For another example, a power trigger threshold and a temperature detection time threshold are set, and when the remaining power of the battery B1 is lower than the power trigger threshold, a temperature detection is performed once every temperature detection time threshold.

[0074] By setting the temperature detection condition, the voltage can be output when temperature detection is required, and the voltage can not be output when temperature detection is not required, thereby avoiding excessive consumption of battery power due to temperature detection.

[0075] The following is based on Figure 2 The overall principle of the temperature acquisition circuit of this application is explained:

[0076] Battery B1 provides power to the microcontroller;

[0077] When the microcontroller triggers the temperature detection condition, it outputs a voltage to the first resistor R1, and the voltage of the control module 100 is transmitted to the cathode of the Zener diode D1 through the first resistor R1. The Zener diode D1 breaks down in reverse, and the cathode voltage of the Zener diode D1 will be maintained at its regulated value to obtain the target voltage;

[0078] The temperature-sensitive resistor RT changes its resistance value based on the operating environment temperature, and the target voltage is divided by the second resistor R2 and the temperature-sensitive resistor RT to obtain a temperature signal;

[0079] The temperature signal is filtered out through an RC filter composed of a third resistor R3 and a first capacitor C1 to remove ripples and then output to the collection end of the microcontroller;

[0080] The microcontroller determines the operating environment temperature from the temperature signal.

[0081] The utility model also protects an intelligent remote controller, which includes a battery B1 and a temperature acquisition circuit. The structure of the temperature acquisition circuit can refer to the above embodiment and will not be described in detail here. As a matter of course, since the intelligent remote controller of this embodiment adopts the technical solution of the above temperature acquisition circuit, the intelligent remote controller has all the beneficial effects of the above temperature acquisition circuit.

[0082] Furthermore, the intelligent remote controller further comprises a battery power detection module; the detection end of the battery power detection module is connected to the battery B1, and the output end of the battery power detection module is connected to the control module 100 in the temperature acquisition circuit; wherein:

[0083] The battery power detection module is used to detect the remaining power of the battery B1, obtain a power signal, and send the power signal to the control module 100;

[0084] The control module 100 is used to determine the remaining power of the battery B1 according to the power signal and the operating environment temperature.

[0085] In practical applications, there is a correlation between the battery power consumption rate and the temperature. Specifically, the lower the temperature, the faster the battery power consumption rate. Therefore, in order to better detect the remaining power of the battery B1, it is necessary to simultaneously detect the operating environment temperature.

[0086] The detection method of the power signal can be set based on actual needs and is not limited here.

[0087] After acquiring the power signal and the temperature signal, the control module 100 determines the operating environment temperature through the temperature signal; and determines the power change curve corresponding to the operating environment temperature, and matches the remaining power corresponding to the power signal in the power change curve; the power change curve corresponding to the operating environment temperature can be determined in advance based on experiments or the performance of battery B1 and stored in the control module 100.

[0088] Furthermore, the intelligent remote controller further comprises a display module, wherein the control end of the display module is connected to the signal output end of the control module 100; wherein:

[0089] The control module 100 is used to determine display information according to the remaining power of the battery B1 and send the display information to the display module;

[0090] The display module is used to perform a display operation according to the display information.

[0091] After determining the remaining power, in order to enable the user to know the power status of the battery B1, the remaining power can be indicated; the specific indication method can be set based on actual application needs, including but not limited to indicating on the smart remote controller body, indicating on the device connected to the smart remote controller;

[0092] When indicating on the smart remote control body, the display module may include a light emitting diode, and determine the indication method of the light emitting diode corresponding to the remaining power, so as to indicate the remaining power through the light emitting diode; the light emitting method includes but is not limited to restrictions on color and flashing frequency; for example, when the remaining power is low, the red light emitting diode is controlled to light up, and when the remaining power is high, the green light emitting diode is controlled to light up, and when the remaining power is about to be consumed, the red light emitting diode is controlled to flash; the different power states of the above-mentioned low remaining power, high remaining power, and about to be consumed lights can be determined based on the specific needs to set the power state threshold to determine, and will not be repeated here. It should be noted that at different points in time and after the temperature, the battery power consumption rate is different. Therefore, when indicating the remaining power through the LED, the final indication method can be determined in combination with the operating environment temperature; for example, different power status thresholds are set for different operating environment temperatures. For example, when the operating environment temperature is low, the battery power consumption rate is faster. Therefore, reminders are needed when more remaining power is required. The power status thresholds corresponding to the lower operating environment temperature in each state can be increased. For example, at 20°C, the indication method corresponding to the 30% power status threshold is the red LED power, and the indication method corresponding to the 10% power status threshold is the flashing red LED; and at -10°C, the indication method corresponding to the 35% power status threshold is set to the red LED power, and the indication method corresponding to the 15% power status threshold is the flashing red LED.

[0093] When indicating on a device connected to the smart remote control, the indication module can be a communication module originally set up for the smart remote control. After determining the remaining power, the information containing the remaining power is sent to the device connected to the smart remote control through the indication module, so that the device displays the remaining power indication signal, thereby realizing the indication function.
