Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For the convenience of understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.
The scheme can be applied to vehicle-mounted air conditioners of most vehicles such as buses and buses, when various vehicles enter the road with relatively poor conditions and still run at the speed on a flat road, or the vehicle cannot be prepared for speed reduction in advance because a driver cannot predict the road conditions in front, so that the vehicle can only slow down after running for a certain distance on the road with relatively poor conditions, the vehicle-mounted air conditioner causes mechanical damage under the condition that the vehicle is violently jolted, an outer fan of the vehicle-mounted air conditioner normally blows outwards at a high speed in the running process, and a downward reaction force can be generated. When the vehicle runs on a bumpy road surface, a larger downward force is generated relative to when the rotation speed of the fan is small, and the vibration acceleration is increased. Meanwhile, the compressor has higher operating frequency under normal conditions, larger resonance can be generated, and the vibration aggravation on the compressor can be caused if the vibration acceleration of the vehicle is added on a bumpy road surface, so that the mechanical stress of the copper pipe connected with the two ends of the compressor is increased, and the risks of pipe breakage, refrigerant leakage and the like exist. By the scheme, the vehicle-mounted air conditioner can automatically adjust the running state, and the mechanical damage probability is reduced.
Fig. 1 is a schematic flow chart of a vehicle-mounted air conditioner control method according to an embodiment of the present invention, and as shown in fig. 1, the method specifically includes:
and S11, acquiring the vibration acceleration of the vehicle in the running process of the vehicle.
During the running process of the vehicle, due to the fact that parts of road surfaces are damaged seriously in a hollow mode and road conditions are poor, vibration acceleration of the vehicle in the vertical direction or the horizontal direction is overlarge, the vibration acceleration of the vehicle is detected through an acceleration sensor arranged on an air conditioner external unit on the vehicle, and the vibration acceleration is obtained and comprises horizontal vibration acceleration and vertical vibration acceleration.
Optionally, the mode of judging the magnitude of the horizontal vibration acceleration and the magnitude of the vertical vibration acceleration of the vehicle through the acceleration sensor can be completed through an image recognition technology, in the running process of the vehicle, a road surface image is collected in real time, the road surface flatness in the image is recognized, the acceleration condition of the same road surface by the acceleration sensor is compared, the model establishment of the image recognition technology is completed, and whether the acceleration at the moment exceeds a threshold value is judged when the flatness is lower than the threshold value, so that the vehicle-mounted air conditioner can automatically adjust the running state and remind a driver of slowing down and crawling.
And S12, determining a control strategy of the vehicle air conditioner based on the vibration acceleration.
In the embodiment of the invention, a control rule of the vehicle-mounted air conditioner is preset, and the running state of the vehicle-mounted air conditioner is controlled according to the rule.
Further, judging whether the vehicle-mounted air conditioner meets a control rule under the current condition according to the acquired horizontal vibration acceleration and the acquired vertical vibration acceleration of the vehicle, and if the current condition meets the control rule of the vehicle-mounted air conditioner, determining a control strategy of the vehicle-mounted air conditioner (adjusting the running state of the vehicle-mounted air conditioner); and if the current situation does not accord with the control rule of the vehicle-mounted air conditioner, controlling the running state of the vehicle-mounted air conditioner to be unchanged.
In an alternative of the embodiment of the invention, the control rule of the in-vehicle air conditioner is provided with different determination conditions that can be determined according to the horizontal vibration acceleration and the vertical vibration acceleration of the vehicle.
For example, a first threshold value (e.g., 0.65 gm/s) corresponding to the horizontal vibration acceleration of the vehicle is set2) Setting a second threshold value (e.g., 1.2 gm/s) corresponding to the vertical vibration acceleration of the vehicle2) Wherein g is the acceleration of gravity.
The conditions corresponding to the control rule according with the vehicle-mounted air conditioner comprise: the horizontal vibration acceleration of the vehicle is equal to or greater than a first threshold value or the vertical vibration acceleration of the vehicle is equal to or greater than a second threshold value.
And S13, adjusting the operation parameters of the vehicle-mounted air conditioner based on the control strategy.
In the embodiment of the invention, the operation parameters of the vehicle-mounted air conditioner can comprise the rotating speed of an outer fan of the vehicle-mounted air conditioner and the frequency of a compressor of the vehicle-mounted air conditioner;
the control strategy can be to reduce the rotating speed of the external fan of the vehicle-mounted air conditioner and the frequency of the compressor of the vehicle-mounted air conditioner, or to control the rotating speed of the external fan of the vehicle-mounted air conditioner and the frequency of the compressor of the vehicle-mounted air conditioner to be unchanged.
If the control strategy of the vehicle-mounted air conditioner is determined to be adjusting the running state of the vehicle-mounted air conditioner, the rotating speed of an outer fan of the vehicle-mounted air conditioner and the frequency of a compressor of the vehicle-mounted air conditioner are reduced, so that the vehicle-mounted air conditioner can automatically control the running state, and excessive mechanical damage is avoided.
According to the vehicle-mounted air conditioner control scheme provided by the embodiment of the invention, the vibration acceleration of the vehicle is obtained in the driving process of the vehicle; determining a control strategy of the vehicle-mounted air conditioner based on the vibration acceleration; and adjusting the operation parameters of the vehicle-mounted air conditioner based on the control strategy. By the method, the vehicle-mounted air conditioner can adjust the running state when the vehicle jolts violently, and mechanical damage is reduced.
Fig. 2 is a schematic flow chart of another vehicle-mounted air conditioner control method according to an embodiment of the present invention, and as shown in fig. 2, the method specifically includes:
and S21, acquiring the vibration acceleration of the vehicle in the running process of the vehicle.
During the running process of the vehicle, the built-in processing system of the vehicle-mounted air conditioner sends an instruction to an acceleration sensor arranged on an external unit of the vehicle-mounted air conditioner in real time, so that the acceleration sensor detects the horizontal vibration acceleration and the vertical vibration acceleration of the vehicle in real time, and the acceleration sensor sends the detected horizontal vibration acceleration and the detected vertical vibration acceleration of the vehicle to the built-in processing system of the vehicle-mounted air conditioner.
For example, the horizontal vibration acceleration of the vehicle acquired may be 0.7gm/s2And the vertical vibration acceleration may be 1.3gm/s2。
And S22, if the horizontal vibration acceleration is larger than or equal to a first threshold value or the vertical vibration acceleration is larger than or equal to a second threshold value, the control strategy is to adjust the running state of the vehicle-mounted air conditioner.
In the embodiment of the present invention, a first threshold value (e.g., 0.6 gm/s) corresponding to the horizontal vibration acceleration of the vehicle is set2) Setting a second threshold value (e.g., 1.3 gm/s) corresponding to the vertical vibration acceleration of the vehicle2)。
The conditions corresponding to the control rule according with the vehicle-mounted air conditioner comprise:
the horizontal vibration acceleration of the vehicle is equal to or greater than a first threshold value or the vertical vibration acceleration of the vehicle is equal to or greater than a second threshold value.
For example, the horizontal vibration acceleration of the vehicle is 0.6gm/s or more2The vertical vibration acceleration of the vehicle is more than or equal to 1.3gm/s2And if so, the control rule of the vehicle-mounted air conditioner is met, and the running state of the vehicle-mounted air conditioner is adjusted.
And S23, if the horizontal vibration acceleration is smaller than the first threshold value or the vertical vibration acceleration is smaller than the second threshold value, the control strategy is to control the running state of the vehicle-mounted air conditioner to be unchanged.
In the embodiment of the present invention, a first threshold value (e.g., 0.5gm/s) corresponding to the horizontal vibration acceleration of the vehicle is set2) Setting a second threshold value (e.g., 1.1gm/s) corresponding to the vertical vibration acceleration of the vehicle2)。
The conditions corresponding to the control rule which accords with the condition that the vehicle-mounted air conditioner keeps the running state unchanged comprise:
the horizontal vibration acceleration of the vehicle is less than a first threshold or the vertical vibration acceleration of the vehicle is less than a second threshold.
For example, the horizontal vibration acceleration of the vehicle is less than 0.5gm/s2The vertical vibration acceleration of the vehicle is less than 1.1gm/s2And if so, conforming to the control rule that the running state of the vehicle-mounted air conditioner is kept unchanged, and keeping the running state of the vehicle-mounted air conditioner unchanged.
And S24, if the control strategy is to adjust the running state of the vehicle-mounted air conditioner, reducing the rotating speed of an external fan of the vehicle-mounted air conditioner to a third threshold value and reducing the frequency of a compressor of the vehicle-mounted air conditioner to a fourth threshold value.
In the embodiment of the invention, if the operation state of the vehicle-mounted air conditioner is determined to be adjusted, an instruction is sent to the vehicle-mounted air conditioner external fan, so that the rotating speed of the vehicle-mounted air conditioner external fan is reduced from the rotating speed during operation to the lowest rotating speed set value under the condition that the working capacity of the air conditioner is not influenced, and meanwhile, an instruction is sent to the compressor of the vehicle-mounted air conditioner, so that the compressor receives the instruction and responds to the instruction to reduce the compression frequency to the set value.
For example, the rotating speed of the external fan of the vehicle-mounted air conditioner is reduced from 4000r/min to 2000r/min during normal operation, and the compression frequency of the compressor of the vehicle-mounted air conditioner is reduced from 40Hz to 30Hz during normal operation.
And S25, if the running time of the vehicle is longer than a first preset time in the state that the horizontal vibration acceleration is smaller than the first threshold and the vertical vibration acceleration is smaller than the second threshold, adjusting the rotating speed of the external fan and the frequency of the compressor to initial values, wherein the initial values are state values before the rotating speed of the external fan and the frequency of the compressor are adjusted.
In the embodiment of the invention, after the rotating speed of the external fan and the compression frequency of the compressor of the vehicle-mounted air conditioner are adjusted, the vehicle continues to run, the vehicle-mounted air conditioner continues to run, and when the fact that the running time of the vehicle in the state that the horizontal vibration acceleration is smaller than a first threshold value (for example, 0.5gm/s) and the vertical vibration acceleration is smaller than a second threshold value (for example, 1.1gm/s) is larger than a first preset time (for example, 5 minutes) is detected in the running process of the vehicle, the rotating speed of the external fan and the frequency of the compressor of the vehicle-mounted air conditioner are restored to the state values before adjustment is carried out, so that the external fan and the compressor of the vehicle-mounted air.
For example, if the rotating speed of the external fan of the vehicle-mounted air conditioner is 4000r/min during normal operation and the compression frequency of the compressor of the vehicle-mounted air conditioner is 40Hz during normal operation, the horizontal vibration acceleration of the vehicle is less than 0.5gm/s2And the vertical vibration acceleration is less than 1.1gm/s2If the running time is longer than 5 minutes, the rotating speed of an external fan of the vehicle-mounted air conditioner is restored to 4000r/min, and the frequency of a compressor is restored to 40 Hz.
And S26, if the control strategy is to adjust the running state of the vehicle-mounted air conditioner, displaying a reminding message, and recording the target position information of the road section corresponding to the horizontal vibration acceleration value which is greater than or equal to a first threshold value or the vertical vibration acceleration value which is greater than or equal to a second threshold value.
If the control strategy is to adjust the running state of the vehicle-mounted air conditioner, a message for reminding a driver of slowing down and crawling due to the road surface problem is generated while the running state of the vehicle-mounted air conditioner is automatically adjusted, and the corresponding road section is located through a GPS when the horizontal vibration acceleration of the vehicle is larger than or equal to a first threshold value or the vertical vibration acceleration of the vehicle is larger than or equal to a second threshold value, and the position information of the road section is recorded as target position information.
And S27, sending the target position information to a central control platform so that the central control platform marks the target position information on a map, wherein the target position information is a position with poor road conditions.
The position information of the corresponding road section when the horizontal vibration acceleration of the vehicle positioned by the GPS is greater than or equal to a first threshold value or the vertical vibration acceleration of the vehicle is greater than or equal to a second threshold value is uploaded to the central control platform, so that the central control platform marks the road condition difference of the position on the internal electronic map, and the driver is warned of the road condition difference in front of the vehicle and needs to slow down for early warning of the vehicle before the subsequent vehicle runs to the road section.
Optionally, when the vehicle runs on a plurality of road sections with poor road conditions, the built-in system of the vehicle-mounted air conditioner records and uploads the position information of the road sections with poor road conditions to the central control platform, and the central control platform records the position information set of the road sections with poor road conditions, so that when the position information of all the road sections with poor road conditions can be obtained, the vehicle can be reminded in time when the vehicle runs on the road.
And S28, acquiring the current position information of the vehicle in real time, and sending the current position information to the central control platform so that the central control platform identifies the current road condition state based on the current position information.
According to the GPS positioning technology, the current driving position information of the vehicle is obtained in real time, the current position information of the vehicle is sent to the central control platform in real time, and after the central control platform receives the current position information of the vehicle, the current position information of the vehicle is compared with the position information of the road condition difference marked on the map, and the road condition state corresponding to the current position information of the vehicle is obtained.
And S29, receiving an identification message returned by the central control platform in response to the current position information.
In the embodiment of the invention, the central control platform sends the road condition state corresponding to the identified current position information of the vehicle to the built-in system of the vehicle-mounted air conditioner, the identification result may be the road condition difference corresponding to the current position information, and the identification result may also be the normal road condition corresponding to the current position information.
And S210, if the current position information is consistent with the target position information, displaying the current road section with poor road condition of the vehicle.
And if the identification result is the road condition difference corresponding to the current position information of the vehicle, generating a reminding message to remind a driver of the road condition difference of the road section in front of the driver, and preparing for slowing down and slowly running in advance to avoid violent jolt of the vehicle.
And S211, if the current position information is inconsistent with the target position information, displaying the road section of the vehicle in the normal road condition.
And if the identification result is that the road condition corresponding to the current position information of the vehicle is normal, displaying that the road condition of the front road section is normal, and informing a driver that the vehicle can normally run.
