It should be noted that the structure of fig. 1 is not limited to the scale of the carrying apparatus 100, and it may also have other functional modules, which are not described in detail herein.
Continuing with the example of the carrying device 100 shown in fig. 1, in order to implement the thermostatic control function, the main control unit 101 is configured to:
the current temperature of the outlet port 106 is obtained.
And judging whether the current temperature is less than or equal to the difference value between the target temperature and the first temperature threshold value.
And if the current temperature is less than or equal to the difference value, executing a heating control process until the difference value between the current temperature and the target temperature is within a preset temperature range.
And if the current temperature is greater than the difference value, executing a refrigeration control process until the difference value between the current temperature and the target temperature is within a preset temperature range.
Through the embodiment, the temperature of the air outlet can be constantly controlled within a target temperature range, and a constant temperature control function is achieved.
In a possible implementation, the current temperature of the air outlet 106 may be obtained by: the first temperature sensor 105 periodically collects the current temperature and transmits the collected temperature to the main control unit 101. For example, the temperature is collected every 3 seconds, or every time a heating or cooling process is performed, which is not limited herein.
In a possible embodiment, assuming that the target temperature is Tg, the mode setting may be performed by a user through a human-computer interface, for example, manual setting may be selected, automatic control may also be performed, or automatic control may be performed by default if no selection is made, and then the corresponding Tg is the default temperature. The first temperature threshold may be preset according to actual requirements, for example, the first temperature threshold Δ T1 is set to be 1 ℃, and the target temperature Tg is set to be 20 ℃.
For example, Tg is 20 ℃,. DELTA.T 1 is 1 ℃, if the current temperature T is 18 ℃, then T < Tg-. DELTA.T 1 indicates that the carrying apparatus 100 is currently low and needs to be heated so as to keep the current temperature consistent with the target temperature; if the current temperature is 24 ℃, T > Tg- Δ T1, which indicates that the current temperature of the carrying device 100 is higher and needs to be cooled, so that the current temperature is within the target temperature range, thereby realizing the constant temperature function.
In one possible embodiment, the preset temperature range may be set according to the above-mentioned first temperature threshold, for example, the preset temperature range may be [ -. DELTA.T 1,. DELTA.T 1], if the difference between the current temperature T and Tg is within [ -. DELTA.T 1,. DELTA.T 1], it is indicated that the seat has currently reached the target temperature range, and at this time, the current temperature T of the air outlet 106 may be continuously collected without any control action.
It should be noted that the current temperature refers to the temperature of the air outlet 106 after the carrying apparatus 100 has been operated for a period of time, during which the heating device 102, the cooling device 103, and the ventilation device 104 may have been opened and closed successively; assuming that the current temperature is just started up in the carrier 100, at this time, it may be considered that the heating device 102, the cooling device 103, and the ventilation device 104 are not working, the obtained current temperature T is the initial temperature value T0 of the carrier 100, and at this time, an absolute value of a difference between the target temperature Tg and the initial temperature value T0 is smaller than the first temperature threshold Δ T1, which indicates that the target temperature range is reached, and the first temperature sensor 105 may continue to sample the current temperature without performing a heating process or a cooling process or starting ventilation.
Optionally, based on the outlet schematic diagram shown in fig. 4, the manner of obtaining the current temperature of the outlet 106 may be: the main control unit 101 is specifically configured to:
if the air outlet 106 has a single first temperature sensor 105, taking the temperature detected by the single first temperature sensor 105 as the current temperature;
if the air outlet 106 has a plurality of first temperature sensors 105, the current temperature is determined according to the weights corresponding to the first temperature sensors 105 and the detected temperatures.
For example, in the case of the temperature sensor array shown in fig. 4, there are n first temperature sensors 105, and the weight corresponding to each first temperature sensor 105 is denoted as WiThe detected temperature is TiCalculating the current temperature T-T1W 1+ T2W 2+ … Tn Wn according to the weight, wherein W1+W2+…Wn=1。
Optionally, in order to implement the ventilation function, after acquiring the current temperature of the air outlet 106, the main control unit 101 may further be configured to:
and if the absolute value of the difference value between the current temperature and the target temperature is determined not to be within the preset temperature range, controlling the ventilation device to start.
And if the absolute value of the difference value between the current temperature and the target temperature is determined to be within the preset temperature range, continuing to execute the step of obtaining the current temperature of the air outlet.
In this embodiment, when the difference between T and Tg is not within the preset temperature range, it indicates that the current temperature of the seat is too high or too low, the ventilation device 104 needs to be turned on, and the purpose of turning on the ventilation device 104 is to form warm air in the subsequent heating control flow and bring the warm air to the position of the first sensor 105 for detection, or form cold air in the subsequent cooling control flow and bring the cold air to the position of the first sensor 105 for detection.
For example, if the predetermined temperature range is [ -1, 1], Tg ═ 20 ℃, T ═ 18 ℃, or T ═ 22 ℃, then the ventilation device 104 needs to be turned on.
Optionally, an embodiment of executing a heating control process is given below, that is, the main control unit 101 is specifically configured to:
if the current temperature is less than or equal to the difference, controlling the heating device 102 to start under the condition that the current temperature is less than or equal to the difference between the target temperature and the second temperature threshold;
and when the difference value between the acquired current temperature and the target temperature is within a preset temperature range, controlling the heating device 102 to be switched off.
Wherein the first temperature threshold is less than the second temperature threshold.
In this embodiment, the heating function is turned on only when the current temperature T is lower than a certain condition, that is, the current temperature T satisfies T<Under the condition of Tg- Δ T1, T is also required to be satisfied<=Tg-△Th1Wherein, Δ Th1Is the second temperature threshold, Δ Th1If the temperature is larger than delta T1, the heating function is started.
For example, Tg 20 ℃, ° T1 1 ℃, ° Th12 ℃ if T is 18 ℃, in which case T is<=Tg-△Th1Then the heating means 102 are controlled to be activated, while the first sensor 105 is still continuously detecting the current temperature T, once it detects a T satisfying the difference from the target temperature Tg of- Δ T1, Δ T1]If so, the heating device 102 is turned off; otherwise; if T is 18.5 ℃, if the heating device 102 is in the working state originally, controlling the heating device 102 to be closed; if the heating device 102 is not activated at this time, the heating device 102 is not controlled to be activated.
It will be appreciated that during operation of the heating device 102, the first temperature sensor 105 continuously senses the current temperature T of the outlet vent 106, once T>Tg-△Th1The heating device 102 is controlled to be turned off.
Optionally, this implementation also provides an implementation manner of executing a refrigeration control flow, that is, the main control unit 101 is specifically configured to:
if the current temperature is greater than the difference, controlling the refrigeration element 1032 and the refrigeration fan 1034 to start if the current temperature is greater than or equal to the difference between the target temperature and the third temperature threshold;
when the difference between the acquired current temperature and the target temperature is within a preset temperature range, the cooling element 1032 and the cooling fan 1034 are controlled to be turned off.
Among them, a cooling fan 1034 for cooling the air around the cooling element 1032 to the ventilation duct 107.
In this embodiment, the third temperature threshold is Δ Tc1At the current temperature T, satisfies T<Under the condition of Tg- Δ T1, T is also required to be satisfied>=Tg+△Tc1The refrigeration function is turned on.
In a possible embodiment, the third temperature threshold is Δ Tc1May be related to a second temperature threshold DeltaTh1The same or different, that is, in practical implementation, a threshold may be set to implement the heating process and the cooling process.
For example, Tg 20 ℃, ° T1 1 ℃, ° Th12 deg.C if T is 22 deg.C, at which time T is>=Tg+△Th1Then control the refrigeration device 103 to start, andwhile the first sensor 105 is still continuously detecting the current temperature T, the difference between the detected T and the target temperature Tg is [ -. DELTA.T 1,. DELTA.T 1]In this case, the cooling device 103 is turned off. Otherwise; if T is 21.5 ℃, controlling the refrigeration device 103 to be closed if the refrigeration device 103 is in an original working state at the moment; if the cooling device 103 is not started at this time, the heating device 102 is not controlled to be started any more.
It will be appreciated that during operation of the refrigeration device 103, the first temperature sensor 105 continuously senses the current temperature T of the outlet vent 106, once T<Tg+△Th1The refrigeration device 103 is controlled to be turned off.
Alternatively, in order to grasp the operating state of the heating device 102 or the cooling device 103, even if an abnormal situation is found, the following also presents a possible embodiment, the main control unit 101, further configured to:
acquiring the temperature of the heating device 102, and if the heating device 102 is determined to be in an abnormal state according to the temperature, outputting the abnormal state; or; acquiring the temperature of the refrigeration device 103; if it is determined that the refrigeration apparatus 103 is in an abnormal state based on the temperature, the abnormal state is output.
It can be understood that, for the heating device 102 or the cooling device 103, overload, short circuit, and failure may occur during operation, therefore, in order to find such abnormality in time, the main control unit 101 may obtain the temperature detected by the second temperature sensor 1021 in the heating device 102, or obtain the temperature detected by the third temperature sensor 1031 in the cooling device 103, determine whether the heating device 102 or the cooling device 103 is in any one of the states of overload, short circuit, and failure according to the obtained temperature, and once it is determined that the heating device 102 or the cooling device 103 is in the abnormal state, immediately present the state to a user, thereby facilitating the user to brake in time and ensuring the safety of the device.
Alternatively, the above description describes the implementation of the heating control process and the cooling control process in the thermostatic control process, and it can be understood that, in order to achieve the difference between the current temperature and the target temperature within the preset range, the voltage or the current or the power applied to any one of the heating device 102, the cooling device 103 or the ventilation device 104 needs to be continuously adjusted in the heating or cooling process to achieve the effect of adjusting the temperature, and therefore, the main control unit 101 is further configured to:
