Description
Technical Field
The invention relates to the technical field of temperature detection, in particular to a temperature measuring device and an electromagnetic heating device.
Background
Thermoelectric generation has been increasingly used in many applications where power is required. However, the phenomenon that the temperature difference between the cold end and the hot end of the thermoelectric generation module is not large also often exists. When the thermoelectric generation module generates insufficient power to maintain the power of the entire circuit system, a battery is required to supply the power. However, in some applications, for example, in a temperature measuring device, if temperature acquisition and data transmission are required at this time, current consumption is large, and a general battery is not maintained for a long time, so that it is necessary to increase the capacity of the battery or to process it by other methods. In the related art, when the thermoelectric generation module cannot ensure the power supply of the whole circuit system, certain modules in the whole circuit system can enter a low-power-consumption working mode, but a certain operation key is usually required to be set to realize a low-power-consumption state awakening mode. However, in some applications, it is not preferable to provide an operation key. For example, when the temperature measuring device is applied to measuring the temperature of the pot, if the operation key is set, the defects of incapability of washing operation and the like are caused.
Disclosure of Invention
The present invention aims to solve at least one of the technical problems existing in the prior art or related art.
Therefore, an object of the present invention is to provide a temperature measuring device capable of automatically switching between a sleep operation mode and a normal operation mode, which can meet the use requirement of a user when the user is inconvenient to set an operation key, and provide convenience for the user and save energy.
Another object of the present invention is to provide an electromagnetic heating device with a temperature measuring device.
To achieve the above object, according to an embodiment of a first aspect of the present invention, there is provided a temperature measuring device, including: the thermoelectric power generation module generates voltage according to the temperature difference between the cold end and the hot end; the voltage detection module is connected to the temperature difference power generation module and is used for detecting the voltage value output by the temperature difference power generation module and outputting a control voltage value according to the voltage value; the control module is connected to the voltage detection module and outputs a control signal according to a comparison result of the received control voltage value and a preset voltage value; and the temperature measuring module is connected to the control module and enters a corresponding operation mode according to a control signal from the control module.
According to the temperature measuring device provided by the embodiment of the invention, the voltage detection module is arranged to detect the voltage output by the thermoelectric generation module, and based on the voltage value, the control module can determine what control signal is output so as to enable the temperature measuring module to switch between different operation modes. Through the technical scheme, the technical effect that the temperature measuring module is automatically switched between different modes according to the generated energy of the thermoelectric generation module can be achieved, so that the problem that the operation mode is still required to be switched through the key under the special condition that the operation key is not suitable to be arranged is solved, and the energy conservation and humanization of the temperature measuring device are effectively improved. Meanwhile, as the whole volume of the temperature measuring device is smaller, the operation keys for reducing mode switching can provide space for some keys in special modes to set, and the possibility of misoperation possibly existing in use of a user is avoided.
In the above technical solution, the method may further include: and the wireless transmission module is used for transmitting the measurement result of the temperature measurement module, and is connected to the control module and enters a corresponding operation mode according to the received control signal of the control module.
In this embodiment, the wireless sending module is provided, so that the temperature detected by the temperature measuring module can be wirelessly sent to other terminals (for example, on a mobile phone of a user far away from the temperature measuring module) through the wireless sending module, the effect of real-time monitoring can be achieved, and convenience is brought to the user. In this embodiment, the wireless transmitting module may enter the corresponding operation mode by receiving the control signal sent by the control module. Also, in this embodiment, the wireless transmission module is also controlled by the control signal, so that the wireless transmission module can synchronize with the operation mode of the temperature measurement module without occurrence, and is still in the awake state (i.e., the high power consumption state) when the temperature measurement module is in the sleep state (i.e., the low power consumption state) and does not transmit the temperature measurement signal, and is ready to receive the signal of the temperature measurement module. The wireless transmitting module and the temperature measuring module both receive control signals at the same time, so that the problem that the running states of the wireless transmitting module and the temperature measuring module are not synchronous can be effectively prevented.
In this embodiment, a wireless receiving module is provided so that a signal transmitted from an external device can be received through the module. In this embodiment, the wireless receiving module may also enter the corresponding operation mode by receiving the control signal sent by the control module. Thus, the wireless transmission module and the temperature measurement module can synchronously operate.
In the above technical solution, the control module sends the sleep signal when the control voltage value is less than or equal to the preset voltage value, and sends the wake-up signal when the control voltage value is greater than the preset voltage value during the sleep period.
In this embodiment, the control module determines whether to trigger the sleep or wake-up signal by comparing the control voltage value with a preset voltage value. It should be understood by those skilled in the art that the control module may be an existing chip such as a microprocessor, and such a chip generally has an interrupt pin, and by connecting a control voltage to the interrupt pin, in a normal mode, the level of the interrupt pin is detected to determine whether the sleep state needs to be entered, and if the level is low, the sleep state is entered, and meanwhile, a rising edge interrupt is set; during sleep, if the rising edge of the interrupt pin changes, interrupt processing is entered, and a normal state is entered. I.e. a trigger sleep signal or a trigger wake-up signal is achieved. Therefore, automatic control can be realized, control signals are determined to the greatest extent according to the output of the thermoelectric generation module, and energy conservation is realized.
In the above technical solution, the temperature measurement module, the wireless transmission module and the wireless receiving module enter the sleep operation mode when receiving the sleep signal, and enter the normal operation mode after receiving the wake-up signal.
In this embodiment, after receiving the wake-up signal, the temperature measurement module, the wireless transmission module and the wireless receiving module synchronously enter the normal operation mode, and meanwhile, when the user needs to use the temperature measurement device, the whole device can quickly enter the operation state, so that the user can use the device. Similarly, after the temperature measuring module, the wireless transmitting module and the wireless receiving module receive the dormancy signals, each module synchronously enters the dormancy operation mode, so that the temperature measuring module, the wireless transmitting module and the wireless receiving module can work with the lowest power consumption, and meanwhile, the whole device can save energy to the greatest extent.
In the above technical solution, the control module may enter the sleep operation mode after sending the sleep signal.
In this embodiment, after the control module sends the sleep signal to the temperature measurement module, the wireless sending module and the wireless receiving module, the control module enters the sleep operation mode, so that the control module can only keep the basic interrupt wake-up function, for example, when the change of the rising edge level of the voltage detection module is monitored, the interrupt wake-up is realized, and therefore, the maximum electric energy saving can be ensured.
In the above technical solution, further includes: a rechargeable power module connected to the power module; the power module is connected to the temperature difference power generation module and used for selecting the chargeable power module or the temperature difference power generation module to supply power for the temperature measuring device according to the voltage value output by the temperature difference power generation module.
In this embodiment, having two power supplies to power, and in particular which power supply to use to power, is determined by the power module. When the voltage value output by the temperature difference power generation module is larger than a preset voltage value, the power supply module selects the temperature difference power generation module to supply power to the temperature measuring device; and when the voltage value output by the thermoelectric generation module is smaller than or equal to a preset voltage value, selecting the rechargeable power module to supply power to the temperature measuring device. Therefore, the problem that the temperature measuring module cannot work normally because the output voltage value of the temperature difference power generation module is insufficient for the operation of the temperature measuring device can be solved in the use process.
In the above technical solution, further includes: when the temperature difference power generation module is selected to supply power to the temperature measuring device, the power supply module enables the temperature difference power generation module to charge the rechargeable power supply module.
In this embodiment, when the voltage value output by the thermoelectric generation module is greater than the preset voltage value, the thermoelectric generation module is selected to supply power to the temperature measuring device, and meanwhile, the thermoelectric generation module is enabled to charge the rechargeable power module.
In the above technical solution, the voltage detection module may include: the first voltage dividing resistor and the second voltage dividing resistor are connected in series between the output end of the thermoelectric generation module and the ground, one end of the second voltage dividing resistor is grounded, and the other end of the second voltage dividing resistor is connected to the anode of the diode; and the diode and the capacitor are connected in series between the output end of the thermoelectric generation module and the ground, wherein the cathode of the diode is connected to the output end of the thermoelectric generation module, the anode of the diode is connected to one end of the capacitor, the other end of the capacitor is grounded, and the anode of the diode is connected to the control module.
In this embodiment, by the parallel connection of the two voltage dividing resistors and the capacitor and the clamp diode, it is possible to easily realize output of a high voltage or a low voltage which can be recognized as a high level signal or a low level signal or a level change by the control module when being input to the interrupt pin of the control module, so that it can be determined whether or not the interrupt is enabled, and thus the corresponding control signal is output.
According to an embodiment of the second aspect of the present invention, there is also provided an electromagnetic heating device including: the temperature measuring device as defined in any one of the above embodiments.
It should be understood by those skilled in the art that all devices or apparatuses having the temperature measuring device described in the above embodiments are within the scope of the present invention.

Detailed Description
In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
Fig. 1 shows a block diagram of a temperature measuring device according to a first embodiment of the present invention.
As shown in fig. 1, the temperature measuring device 100 includes: the thermoelectric generation module 1 generates voltage according to the temperature difference between the cold end and the hot end; the voltage detection module 2 is connected to the thermoelectric generation module 1 and is used for detecting a voltage value output by the thermoelectric generation module 1 and outputting a control voltage value according to the voltage value; the control module 5 is connected to the voltage detection module 2 and outputs a control signal according to a comparison result of the received control voltage value and a preset voltage value (V1); the temperature measuring module 6 is connected to the control module 5 and enters a corresponding operation mode according to a control signal from the control module 5.
In this embodiment, the temperature measuring device 100 formed by combining the four modules of the thermoelectric generation module 1, the voltage detection module 2, the control module 5 and the temperature measuring module 6 can at least realize that the temperature measuring device 100 can automatically switch the operation modes.
Fig. 2 shows in particular a schematic diagram of a voltage detection module 2 according to an embodiment of the invention. As shown in fig. 2, the voltage detection module 2 includes: the first voltage dividing resistor R1 and the second voltage dividing resistor R2 are connected in series between the output end of the thermoelectric generation module 6 and the ground, wherein one end of the second voltage dividing resistor R2 is grounded, and the other end of the second voltage dividing resistor R2 is connected to the anode of the diode D1. The diode D1 and the capacitor C1 are connected in series between the output terminal of the thermoelectric generation module 6 and the ground, wherein the cathode of the diode D1 is connected to the output terminal of the thermoelectric generation module 6, the anode is connected to one end of the capacitor C1, the other end of the capacitor C1 is grounded, and the anode of the diode is also connected to a pin INT of the control module 5 having an external interrupt function.
As shown in fig. 2, if the temperature difference between the cold end and the hot end of the thermoelectric generation module 6 is small, the voltage output by the thermoelectric generation module 6 is low, the voltage value received by the pin INT of the control module 5 connected to the voltage detection module 2 is low, and when the voltage value is smaller than the predetermined value, the control module 5 considers that the signal is a low level signal. When this voltage value is equal to or higher than the predetermined value, the control module 5 considers this as a high level signal.
As shown in fig. 3, when the temperature difference between the cold end and the hot end of the thermoelectric generation module 6 is less than T1, the corresponding output voltage value is less than V1. If the voltage value received at pin INT is smaller than the predetermined value V1, the control module 5 considers this as a low level signal, and the control module 5 will send out the signal as a sleep signal, i.e. enter the low power consumption state shown in fig. 3. On the contrary, in the low power consumption state, when the temperature difference between the cold end and the hot end of the thermoelectric power generation module 6 is greater than or equal to T1, the corresponding output voltage value is greater than or equal to V1. If the voltage value received by the pin INT is greater than V1, the voltage value may be determined as a high level signal by the control module 5, and at this time, the pin INT changes along a rising edge, and the control module 5 realizes interrupt wake-up, so that the control module 5 sends a wake-up signal, thereby waking up each module in a sleep state, and enabling all modules to enter a normal working mode.
As shown in fig. 3, the voltage value input to pin INT does not exceed V2 (vdd+0.7v), where VDD is the supply voltage of control module 5, because of the presence of diode D1.
Fig. 4 shows a block diagram of a temperature measuring device according to a second embodiment of the present invention.
As shown in fig. 4, in this embodiment, the temperature measuring device 400 includes, in addition to the module shown in fig. 1: a wireless transmitting module 7 for transmitting the measurement result of the temperature measuring module, and a wireless receiving module 8 for receiving an external signal, a rechargeable power module 3, and a power module 4.
In this embodiment, the voltage detection module 2 of the temperature measurement device 400 detects the voltage generated by the thermoelectric generation module 1, and if the detected voltage is greater than the preset voltage value, that is, if the generated energy of the thermoelectric generation module is enough to supply power to the temperature measurement device, a wake-up signal is sent to the control module 5, that is, the control module 5 is notified that the electric energy is enough now, so that all modules can be woken up, and a normal working mode, that is, a high-power consumption mode is entered. If the detection result is smaller than or equal to the preset voltage value, the generated energy of the thermoelectric generation module is insufficient to support the normal operation of the temperature measuring device, and at the moment, a sleep signal is sent to the control module 5, so that the control module 5 controls the corresponding module to enter a sleep mode, namely a low-power consumption mode, and electric energy is saved.
The power module 4 is connected to the thermoelectric power module 1 and the rechargeable power module 3, and is used for selecting the rechargeable power module or the thermoelectric power module to supply power to the temperature measuring device according to the voltage value output by the thermoelectric power module 1. In other words, when the voltage value output from the thermoelectric generation module 1 is sufficiently high, the power module 4 selects the thermoelectric generation module 1 to supply power to the entire temperature measuring device, and does not select the rechargeable power module 3 to supply power. However, when the voltage value output by the thermoelectric generation module 1 is not high enough to supply power to the entire temperature measuring device, the power module 4 will determine to be supplied by the rechargeable power module 3. Therefore, the battery is not used when the high-quality energy is used, and the purposes of prolonging the service life of the battery and saving energy are achieved. For a specific embodiment of the power module 4, it will be appreciated by those skilled in the art that there are numerous ways to implement, for example, the circuit shown in fig. 5.
As shown in fig. 5, the three terminal regulator U2 steps down the V-temperature difference to the battery charging voltage. The charging management module U3 is configured to manage battery charging. Specifically, the divided voltage of the voltage V temperature difference generated by the thermoelectric generation module 1 and the reference voltage Vref are input to both ends of the comparator U1, respectively. When the voltage V temperature difference is higher than the reference voltage Vref, the transistors Q1 and Q2 are conducted, and the voltage V temperature difference generated by the temperature difference is higher than the battery voltage, so that the temperature difference is used for power supply. In contrast, when the partial pressure of the voltage V difference is lower than the reference voltage Vref, both transistors Q1 and Q2 are turned off, and battery power is applied.
In this embodiment, the wireless transmission module 7 may transmit the detected result of the temperature difference module to other local or remote terminals in a wireless transmission manner, so that the user may detect the result in real time. The wireless transmission module 7 is also controlled by the control module 5. And the control signal sent by the control module 5 is received, so that the temperature measuring module 6 and the control module synchronously enter a corresponding operation mode.
The wireless receiving module 8 can receive signals or instructions from other terminals in a wireless manner, meanwhile, the wireless receiving module 8 is also connected with the control module 5, and according to the received control signals of the control module 5, the wireless receiving module 8 can enter corresponding operation modes synchronously with the wireless transmitting module 7 and the temperature measuring module 6.
Fig. 6 shows a schematic view of an electromagnetic heating device using a temperature measuring device according to an embodiment of the present invention. As shown in fig. 6, as one example apparatus using the temperature measuring apparatus of the embodiment of the present invention, an electromagnetic heating apparatus 600 includes a temperature measuring apparatus 400.
Here, it should be understood by those skilled in the art that all devices requiring the application of the temperature measuring device, such as a cooker, a refrigerator, a microwave oven, etc., may use the temperature measuring device according to the embodiment of the present invention.
The technical scheme of the invention is described in detail with reference to the accompanying drawings, and the temperature measuring device capable of automatically switching the sleep operation mode and the normal operation mode meets the use requirement of a user when the operation keys are inconvenient to set, thereby providing convenience for the use of the user and saving energy.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
