Vehicle-mounted air conditioner control method, vehicle-mounted air conditioner and computer readable storage medium
Technical Field
The invention relates to the technical field of vehicle-mounted air conditioners, in particular to a vehicle-mounted air conditioner control method, a vehicle-mounted air conditioner applying the vehicle-mounted air conditioner control method and a computer readable storage medium applying the vehicle-mounted air conditioner control method.
Background
Vehicles provide great convenience for our outdoor activities. The air conditioner is inevitably required in the running and parking processes of the vehicle, part of the vehicle-mounted air conditioner is fixed at the top of the vehicle, and the vehicle-mounted air conditioner is easy to loose and fall off in the using process of the vehicle, so that the fixed state of the vehicle-mounted air conditioner needs to be detected in time.
The existing method is that whether the fastening piece of the fixed air conditioner is loosened is primarily judged by using sound decibels near the fastening piece, larger noise is generated when the fastening piece is loosened, the obtained sound decibels are larger than or equal to preset decibels, the distance from the top end of the fastening piece to the fixed position is further obtained through the photoelectric sensor, whether the fastening piece is loosened is further judged according to the obtained distance from the top end of the fastening piece to the fixed position, and the problem that the accuracy of judging results is affected due to interference of other noise near the fastening piece is solved. However, this method is primarily determined using the noise value, and the distance is determined when the noise value reaches a certain limit. Firstly, the noise value of the whole vehicle comes from each side in the running process, and the judging efficiency is low. Secondly, a large sound exceeding threshold value is a necessary condition for starting to execute distance judgment, and when the noise value is low and the parking air conditioner is loose, judgment cannot be performed, and the noise value is not high when the fastener is broken due to problems such as strength, fatigue and the like.
Therefore, there is a need to consider a better method of detecting the fixed state of the vehicle-mounted air conditioner.

Fig. 1 is a flowchart of an embodiment of a control method of an in-vehicle air conditioner of the present invention.
The invention is further described below with reference to the drawings and examples.
Detailed Description
The control method of the vehicle-mounted air conditioner is an application program applied to the vehicle-mounted air conditioner and is used for defrosting the vehicle-mounted air conditioner when heating. In this embodiment, the vehicle-mounted air conditioner includes an inner unit and an outer unit, the inner unit is installed inside the vehicle body, the outer unit is installed outside the vehicle body, and the inner unit and the outer unit are connected to form a refrigerant loop. The inner machine is provided with a first acceleration sensor, the outer machine is provided with a second acceleration sensor, the first acceleration sensor is used for detecting acceleration data of the inner machine, the second acceleration sensor is used for detecting acceleration data of the outer machine, at least one of the inner machine and the outer machine is provided with a gesture sensor, and the gesture sensor is used for acquiring gesture data of the vehicle-mounted air conditioner.
The vehicle-mounted air conditioner control method comprises the following steps:
as shown in fig. 1, in this embodiment, when the vehicle-mounted air conditioner control method is in operation, step S1 is first performed to obtain acceleration data of the first acceleration sensor and acceleration data of the second acceleration sensor. In order to detect the fixed state of the vehicle-mounted air conditioner, acceleration data of the inner machine and acceleration data of the outer machine are required to be acquired, the acceleration data of the inner machine are acquired through a first acceleration sensor, and the acceleration data of the outer machine are acquired through the outer machine.
After the acceleration data of the inner machine and the outer machine are obtained, step S2 is executed, the current relative displacement value between the inner machine and the outer machine is confirmed according to the acceleration data of the first acceleration sensor and the acceleration data of the second acceleration sensor, and the absolute value of the difference value between the current relative displacement value and the initial relative displacement value is calculated. The initial relative displacement value is obtained by first acquisition after the inner machine and the outer machine are installed and fixed. After the acceleration data of the inner machine and the outer machine are obtained, the acceleration degree is calculatedAnd (3) carrying out secondary integration to obtain displacement data of the first acceleration sensor in the X, Y and Z directions respectively: l11, L12, L13, and obtain displacement data of the second acceleration sensor in the X, Y, Z directions, respectively: the techniques for obtaining displacement data by twice integrating acceleration data are well known to those skilled in the art, and will not be described in detail herein. The relative displacement value between the first acceleration sensor and the second acceleration sensor is obtained by the following formula:the initial conditions of the two acceleration sensors are kept consistent, the initial relative displacement value is zero, namely the L value is zero, the acceleration data of the two acceleration sensors are kept consistent under the assumption that the relative positions of the two current acceleration sensors are unchanged, and the absolute value of the difference value between the current relative displacement value and the initial relative displacement value is zero. When the relative positions of the two acceleration sensors are changed, the absolute value of the difference between the current relative displacement value and the initial relative displacement value is no longer zero, so that the relative displacement of the inner machine and the outer machine can be determined.
Because the vehicle is driven and parked in a reciprocating cycle in the driving process, the internal machine or the external machine of the vehicle-mounted air conditioner inevitably generates some deformation in the moving process of the vehicle, and the parking air conditioner is loose even if the risk of falling occurs due to accumulation of multiple deformation, in this embodiment, the step of calculating the absolute value of the difference between the current relative displacement value and the initial relative displacement value includes: and periodically accumulating the absolute difference values of the current relative displacement value and the last relative displacement value to obtain an accumulated difference value, and taking the accumulated difference value as the absolute difference value of the current relative displacement value and the initial relative displacement value. When the absolute value of the difference between the current relative displacement value and the initial relative displacement value is obtained, the relative displacement values detected for multiple times are accumulated in a preset period, so that the accuracy of data detection can be improved. The preset period may be a set time period, or may be a period when the cumulative difference reaches the preset cumulative difference from zero. In another embodiment, when the current relative displacement value is obtained, multiple relative displacement value detections may be performed and multiple relative displacement values may be averaged to obtain the current relative displacement value.
After confirming the absolute value of the difference between the current relative displacement value and the initial relative displacement value of the inner machine and the outer machine, executing step S3, and sending a corresponding air conditioner fastening state signal according to the range where the absolute value of the difference is located and the current running state of the vehicle. When the absolute value of the difference is in different ranges, the relative displacement degree of the inner machine and the outer machine is different. In addition, the degree of the relative displacement is different in different running states of the vehicle, such as a driving state and a parking state, so that the corresponding air conditioner fastening state signal needs to be sent according to the range where the absolute value of the difference value is located and the current running state of the vehicle, so that the user can know and perform corresponding operation.
In this embodiment, the step of sending the corresponding air conditioner fastening state signal according to the range in which the absolute value of the difference is located and the current running state of the vehicle includes: when the absolute value of the difference value is in a first preset range of the current running state of the vehicle, confirming that the air conditioner is in a fastening state; when the absolute value of the difference value is in a second preset range of the current running state of the vehicle, confirming that the air conditioner is in a loose state, wherein the lower limit value of the second preset range is larger than the upper limit value of the first preset range; when the absolute value of the difference value is in a third preset range of the current running state of the vehicle, the air conditioner is confirmed to be in a falling state, and the lower limit value of the third preset range is larger than the upper limit value of the second preset range. The first preset range, the second preset range and the third preset range are preset according to experimental data. For example, when the current running state of the vehicle is a driving state, the first preset range is less than 10mm, the second preset range is greater than or equal to 10mm and less than 20mm, and the third preset range is greater than or equal to 20mm; the current running state of the vehicle is in a parking state, the first preset range is smaller than 3mm, the second preset range is larger than or equal to 3mm and smaller than 5mm, and the third preset range is larger than or equal to 5mm.
When the air conditioner is confirmed to be in a fastening state, the air conditioner can be confirmed to be in a loosening state without processing, and reminding information can be sent to provide a user for stable maintenance of the air conditioner. When the air conditioner is confirmed to be in the falling state, step S4 is executed, and the displacement value and the acceleration of the inner machine and/or the outer machine in the gravity direction are confirmed according to the attitude data. When the air conditioner is in a fastening state, in order to further determine whether the inner machine or the outer machine falls, attitude data of the air conditioner is required to be acquired to determine displacement values and acceleration of the inner machine and/or the outer machine in the gravity direction for judgment. The attitude data can be obtained through an attitude sensor, and the angles of RX, RY and RZ directions on the attitude sensor can be represented by theta 1, theta 2 and theta 3, and a satellite coordinate system is adopted. The satellite coordinate system can be changed into a fixed coordinate system by using Euler transformation, so that displacement values and accelerations of the inner machine and the outer machine in the gravity direction can be obtained, and Euler transformation of the gesture data is a technology known to those skilled in the art, and is not repeated here.
After confirming the displacement value and the acceleration of the inner machine and/or the outer machine in the gravity direction, executing step S5, and determining the falling state of the inner machine and/or the outer machine according to the displacement value and the acceleration of the inner machine and/or the outer machine in the gravity direction. When the air conditioner is in a loose state, whether the inner machine or the outer machine falls down can be further confirmed through the displacement value and the acceleration of the inner machine and the outer machine in the gravity direction.
In this embodiment, the step of determining the falling state of the inner machine and/or the outer machine according to the displacement value and the acceleration of the inner machine and/or the outer machine in the gravity direction includes: when the displacement value of the inner machine in the gravity direction is larger than a first preset distance and the acceleration of the inner machine in the gravity direction is larger than a first preset acceleration, confirming that the inner machine falls; when the displacement value of the outer machine in the gravity direction is larger than a second preset distance and the acceleration of the outer machine in the gravity direction is larger than a second preset acceleration, confirming that the outer machine falls; when the displacement value of the inner machine in the gravity direction is larger than a first preset distance, the acceleration of the inner machine in the gravity direction is larger than a first preset acceleration, the displacement value of the outer machine in the gravity direction is larger than a second preset distance, and the acceleration of the outer machine in the gravity direction is larger than a second preset acceleration, the inner machine and the outer machine are confirmed to fall down and the vehicle is in a turning state. The first preset distance, the first preset acceleration, the second preset distance and the second preset acceleration are preset according to experimental data, for example, the first preset distance and the second preset distance are 20mm, and the first preset acceleration and the second preset acceleration are 5m/s2. After the inner machine is confirmed to fall or the outer machine is confirmed to fall, a corresponding early warning signal can be sent so that a driver can know and overhaul.
In this embodiment, after the step of confirming that both the inner machine and the outer machine fall and the vehicle is in the rollover state, the method further includes: and carrying out awakening operation on a driver, and if no feedback information exists, carrying out alarm operation. When the inner machine and the outer machine fall down at the same time, the phenomenon that the car is overturned is considered to be possibly caused. Therefore, the method comprises the steps of firstly carrying out awakening operation on a driver, and then carrying out alarming operation if feedback information is not available, so that rescue is facilitated. When the wake-up operation is performed, a sharp sound can be played. When alarm operation is carried out, an alarm signal can be sent to the remote control terminal.
As can be seen from the above, the vehicle-mounted air conditioner control method of the present invention is provided with the first acceleration sensor in the inner machine of the vehicle-mounted air conditioner, and the second acceleration sensor in the outer machine of the vehicle-mounted air conditioner, so that the current relative displacement value between the inner machine and the outer machine can be confirmed through the acceleration data, and the absolute value of the difference between the current relative displacement value and the initial relative displacement value is calculated, thereby determining the relative displacement states of the inner machine and the outer machine, and further confirming the fixed state of the vehicle-mounted air conditioner. By detecting the fixed state of the vehicle-mounted air conditioner by using the acceleration sensor, the detection accuracy can be improved.
