Example one

Fig. 1A is a flowchart of a reminding method according to an embodiment of the present invention, where the embodiment is applicable to a reminding situation, the method may be executed by a reminding device according to an embodiment of the present invention, and the device may be implemented in a software and/or hardware manner, as shown in fig. 1A, the method specifically includes the following steps:

s110, obtaining the temperature outside the cab, the temperature inside the cab, the actual air outlet temperature, the solar radiation intensity, the temperature of the engine compartment, the set temperature, the minimum air quantity, the maximum air outlet temperature and the minimum air outlet temperature.

Specifically, the obtaining mode of the temperature outside the cab, the temperature inside the cab, the actual air outlet temperature, the sunlight radiation intensity and the temperature of the engine compartment can be obtained by collecting through a sensor, the set temperature is the temperature set by the current automatic air conditioner, the minimum air volume is the minimum air volume of the current automatic air conditioner, and the maximum air volume is the maximum air volume of the current automatic air conditioner.

And S120, determining a target air outlet temperature according to the temperature outside the cab, the temperature inside the cab, the actual air outlet temperature, the solar radiation intensity, the temperature of the engine compartment, the set temperature and the minimum air volume.

Specifically, the relationship between the outside temperature of the cab, the inside temperature of the cab, the actual air outlet temperature, the solar radiation intensity, the temperature of the engine compartment, the set temperature and the minimum air volume and the total heat gain of the cab can be obtained first, and then the target air outlet temperature is determined according to the relationship.

Optionally, determining the target air-out temperature according to the temperature outside the cab, the temperature inside the cab, the actual air-out temperature, the solar radiation intensity, the temperature of the engine compartment, the set temperature, and the minimum air volume includes:

Qt＝(K1+K3)To+(-K1-K3-K4-K5Fr)Ti+K2Ts+K5FrTf+(Q6+80K4)；

wherein Qt is total heat, To is the temperature outside the cab, Fr is the target air volume, Ts is the solar radiation intensity, Tf is the actual outlet air temperature, K1, K2, K3, K4 and K5 are constants, Q6 is an error correction coefficient, and when Qt is 0, Fr is Fmin, and Tf is Ttv;

And S130, determining the target air volume according to at least one of the target air outlet temperature, the maximum air outlet temperature, the minimum air volume, the temperature in the cab and the set temperature.

Specifically, the target air volume is determined in two ways, one is that when the target air-out temperature is within the range of the minimum value and the maximum value of the air-out temperature of the air conditioner, the target air volume is the minimum air volume; and the other is that when the target outlet air temperature is out of the range of the minimum outlet air temperature and the maximum outlet air temperature of the air conditioner, the target air volume needs to be obtained by calculation according to the target outlet air temperature, the maximum outlet air temperature, the minimum air volume, the temperature in the cab and the set temperature.

Optionally, determining the target air volume according to at least one of the target air-out temperature, the maximum air-out temperature, the minimum air volume, the temperature in the cab, and the set temperature includes:

Optionally, if the target air-out temperature is less than the minimum air-out temperature, or the target air-out temperature is greater than the maximum air-out temperature, determining the target air volume according to the following formula:

Optionally, if the target air-out temperature is greater than or equal to the minimum air-out temperature, and the target air-out temperature is less than or equal to the maximum air-out temperature, determining the target air volume according to the following formula:

Fr＝Fmin+K7(Tset-Ti)；

And S140, controlling the air conditioner to work at the target air volume.

Specifically, the mode of controlling the air conditioner to operate at the target air volume may be that the current actual air volume is adjusted to the target air volume, and if the current actual air volume is higher than the target air volume, the air volume is reduced until the target air volume is reached, so as to reduce noise.

Fr＝Fmin+K7(Tset-Ti)；

On the premise of meeting the temperature stability and the control precision, the minimum noise can be necessarily obtained by using the minimum air volume (the minimum motor rotating speed), and the optimal energy-saving effect can be obviously obtained by preferentially adjusting the temperature of the air outlet through the air mixing door to control the temperature in the cab on the premise of using the minimum air volume.

In a specific example, the air conditioner controller collects the temperature To outside the cab, the temperature Ti inside the cab, the actual air outlet temperature Tf, and the solar radiation intensity Ts by the response sensor. And calculating the total heat quantity Qt of the cab, and the air conditioner controller comprehensively calculates the collected To, Ti and Ts and the set temperature Tset To obtain that the total heat quantity Qt and Qt of the cab at present have a linear change trend along with the gradual approach of the indoor temperature Ti To the set temperature Tset, and when Qt is 0, the temperature of the cab is stabilized at the current value, so that the aim of the automatic air conditioner is To enable Qt To be 0 when Ti is Tset. And (3) calculating the steady-state target air outlet temperature Ttv, the minimum air quantity Fmin, the maximum air quantity Fmax and the Fmin under the minimum air outlet state, and determining according to the difference and the requirement of different air conditioning systems. In the embodiment of the invention, Fmin is 10% of Fmax, Fmax is the inherent characteristic of the fan in a specific air-conditioning system, and Fmax is a fixed value in the specific air-conditioning system. The air conditioner controller calculates a target air outlet temperature Ttv in the minimum air outlet state based on Fmin and Qt, namely the air conditioner can maintain the average temperature of the cab at Tset by blowing air according to the air temperature Ttv, and the purpose of constant temperature control is achieved. The air conditioner controller controls an air temperature adjusting device (a mixing air door) in the air conditioning system according to Ttv to adjust the actual outlet air temperature Tf to Ttv. And calculating the actual air outlet volume Fr, and introducing a limit air outlet temperature Tfl, namely the actual air outlet temperature when the opening of the mixing air door is 0% or when the opening of the mixing air door is 100%. Tfl represents the lowest or highest outlet air temperature of a particular air conditioning system. And the air conditioner controller calculates a target air quantity Fr according to the target steady-state air outlet temperature Ttv, the minimum allowable air quantity Fmin and the set temperature Tset.

The technical scheme provided by the embodiment of the invention can maximally utilize the refrigerating and heating performances of the air conditioning system and achieve the aim of stabilizing the temperature of the cab by using the minimum air volume. The noise of the cab is optimized, and meanwhile, the small air volume air conditioning system can bring good comfort to the driver and achieve the purpose of reducing the overall energy consumption.

In another specific example, as shown in fig. 1B, the air conditioner controller 1 is connected To the outdoor temperature sensor 2, the indoor temperature sensor 3, the outlet air temperature sensor 4, and the solar radiation sensor 5 through a wire harness, and is configured To collect an outdoor temperature To, an indoor temperature Ti of the driver's cab, an actual outlet air temperature Tf, and a solar radiation intensity Ts. The air conditioner controller 1 is connected with the mixing air door 6 through a wire harness, and the mixing proportion of cold/air is controlled by controlling the opening degree of the mixing air door 6 so as to control the actual air outlet temperature Tf of the air conditioner. The air conditioner controller 1 is connected with the evaporation fan 7 through a wire harness, and the air conditioner air output is controlled by adjusting the voltage at two ends of the evaporation fan 7. The specific control method of the embodiment of the invention comprises the following steps:

step 1: the air conditioner controller collects the temperature To outside the cab, the temperature Ti inside the cab, the actual air outlet temperature Tf and the sunlight radiation intensity Ts through the response sensor.

Step 2: and the air conditioner controller calculates the total heat Qt of the current cab, namely the total heat of the current cab according To the collected outdoor temperature To, the temperature Ti in the cab, the solar radiation intensity Ts and the set temperature Tset. The Qt mainly comprises outdoor heat transfer heat Q1, sunlight radiation heat Q2, heat Q3 brought by air conditioner external circulation, heat Q4 brought by an engine compartment, heat Q5 brought by an air conditioning system and heat Q6 generated by other heat sources in the vehicle. The specific calculation method is as follows:

Qt＝Q1+Q2+Q3+Q4+Q5+Q6

Q1＝K1*(To-Ti)

Q2＝K2*Ts

Q3＝K3*(To-Ti)

q4 ═ K4 ═ Tm-Ti (Tm-Ti), Tm are engine compartment temperatures, and this number does not change much during the actual calibration, taken as 80 ℃.

Q5＝K5*Fr(Tf-Ti)

Q6 is obtained by calibration according to different existing differences of different cabs. Here processed as a constant value and at the same time as an error correction factor.

Taken together, Qt ═ To (K1+ K3) To + (-K1-K3-K4-K5Fr) Ti + K2Ts + K5FrTf + (Q6+80K4) note: according to the law of heat transfer, it is obvious that the K1, K2, K3, K4 and K5 are constants and can be obtained by calculation according to later calibration data.

And step 3: and calculating a steady-state target outlet air temperature Ttv under the condition of Fmin according to Qt, namely the target outlet air temperature when Ti is Tset. Under these conditions, Fr ═ Fmin, Tf ═ Ttv, and Ti ═ Tset in the Qt calculation method. It has been explained above that at steady state Qt is 0 and Fmin is a fixed value determined according to actual demand. From the above conditions it follows that:

0 ═ To (K1+ K3) To + (-K1-K3-K4-K5Fmin) Tset + K2Ts + K5 fminsttv + (Q6+80K4) can be obtained from the formula:

and 4, step 4: the air conditioner controller gradually adjusts the actual air outlet temperature Tf to the steady-state target air outlet temperature Ttv according to Ttv. In order to enable the temperature Ti in the cab to reach the set temperature Tset more quickly, an acceleration coefficient K6 is introduced into the air outlet temperature calculation method, K6 is a number larger than zero, and the system balance speed is higher when K6 is larger according to actual requirements. The specific calculation method is as follows:

Tf＝Ttv+K6*(Tset-Ti)

it is clear from the above formula that when the system reaches equilibrium, Ti is Tset, and when Tf is Ttv. When Tf calculated by the above equation exceeds the adjustment range of the air conditioning system, the blend door stays at the corresponding limit position. And when the (Tset-Ti) is less than or equal to 1, the (Tset-Ti) in the formula of the wind temperature control method is zero.

And 5: and calculating the actual air outlet volume Fr. In order to enable the temperature Ti in the cab to reach the set temperature Tset more quickly, an acceleration coefficient K7 is introduced into the air outlet volume method, K7 is a number larger than zero, and the system balance speed is higher when K7 is larger according to actual requirements. The specific calculation method is as follows:

when Tfmin < Ttv < Tfmax: fr ═ Fmin + K7 (Tset-Ti);

when Ttv > Tfmax or Ttv < Tfmin:

according to the heat input formula of the air conditioning system, the steady state Q5 is K5Fmin (Ttr-Tset) K5Fr (Tfl-Tset)

Can be obtained from the above formula

It is obvious that

That is, the air volume compensation value when the target steady-state outlet air temperature Ttr is not within the actual outlet air temperature range. From the above calculation, it is obvious to conclude that when the cab is in a steady state, Ti is Tset, and when the target steady-state air-out temperature Ttr is within the air-conditioning capacity range, the air-conditioning system always operates with the minimum air volume Fmin, and at this time, the energy consumption is lowest and the noise is minimum. When the Ttr exceeds the adjustable range of the air conditioner, the air door of the air conditioner is at the limit position, the actual air outlet temperature Fr is the limit air outlet temperature Frl, the utilization rate of the refrigerating and heating capacity of the air conditioning system is the maximum, the air temperature difference is partially compensated by the air volume, the temperature of the cab can still be ensured to be at the steady state, and the air volume is the minimum air volume which can be used by the specific air conditioning system to keep the steady state of the cab.

According to the technical scheme of the embodiment, the temperature outside the cab, the temperature inside the cab, the actual air outlet temperature, the solar radiation intensity, the temperature of the engine compartment, the set temperature, the minimum air volume, the maximum air outlet temperature and the minimum air outlet temperature are obtained; determining a target air outlet temperature according to the temperature outside the cab, the temperature inside the cab, the actual air outlet temperature, the solar radiation intensity, the temperature of the engine compartment, the set temperature and the minimum air volume; determining a target air volume according to at least one of the target air outlet temperature, the maximum air outlet temperature, the minimum air volume, the temperature in the cab and the set temperature; the air conditioner is controlled to work at the target air volume, so that the minimum air volume can be used to meet the comfort requirement of a cab and the control precision, and meanwhile, the optimal noise and energy-saving effect are obtained.
