Based on the hardware structure of the equipment, the embodiment of the parking space management method is provided.
Referring to fig. 2, in a first embodiment of the parking space management method of the present invention, the parking space management method includes:
in step S10, the weight of the target space is detected based on the ground coil sensor.
The parking space management method in this embodiment is applied to parking space management equipment (also called a terminal, equipment or terminal equipment), and the parking space management equipment includes equipment with a data acquisition or data processing function, such as a PC, a smart phone, a tablet computer, a ground induction coil sensor, a distance measuring device (such as an infrared distance meter), and the like.
In this implementation, the ground induction coil sensor is buried underground in the target parking space, and the ground induction coil sensor can detect the weight generated in the target parking space, and therefore, when no object exists in the target parking space, due to the problem of the accuracy of the ground bearing or the ground induction coil sensor, the result of the weight detection performed by the ground induction coil sensor in the target parking space is a value greater than zero, and the specific value of the value greater than zero, the sensitivity of the ground induction coil sensor, and the principle embodiment of the weight detection performed by the ground induction coil sensor do not need to be detailed or limited.
Step S20, when it is detected that there is an ascending trend of the weight in the target parking space, taking a time corresponding to the ascending trend as an entry time of the vehicle.
In this embodiment, as shown in fig. 7, a ground coil sensor is embedded under an area where a first parking space (not shown) is located, when a vehicle enters the second parking space from outside, the ground coil sensor will detect a weight change caused by the first vehicle entering, and when the vehicle gradually enters the second parking space, the weight change is in an ascending trend, and when the ground coil sensor detects that the weight of the vehicle in the second parking space is in the ascending trend, the parking space management program takes a time when the ground coil sensor detects the ascending trend as an entry time of the first vehicle, so as to calculate a parking cost of the first vehicle. The target parking space is a fourth parking space in this embodiment, and the entry time is the time when the vehicle enters the parking space.
And step S30, when the weight descending trend in the target parking space is detected, taking the time corresponding to the descending trend as the departure time of the vehicle.
In this embodiment, as shown in fig. 7, a ground coil sensor is embedded under an area where a second parking space (not shown) is located, when the second vehicle exits the second parking space from inside to outside, the ground coil sensor detects a weight change caused by the exit of the second vehicle, and when the second vehicle gradually exits the second parking space, the weight change is in a downward trend, and when the ground coil sensor detects that the weight of the second parking space is in the downward trend, the parking space management program takes a time when the ground coil sensor detects the downward trend as an exit time of the second vehicle, so as to calculate a parking cost of the second vehicle. The parking space is the target parking space in the application scene, and the departure time refers to the time when the vehicle drives away from the parking space.
In this embodiment, the weight of the target parking space is detected by the ground coil sensor, when the ground coil sensor detects that there is an ascending trend of the weight in the target parking space, the parking space management program takes the time when the ground coil sensor detects the ascending trend as the entry time of the vehicle, and when the ground coil sensor detects that there is a descending trend of the weight in the target parking space, the parking space management program takes the time when the ground coil sensor detects the descending trend as the exit time of the vehicle, so that the entry time and the exit time of the vehicle are determined more accurately.
Further, with reference to fig. 3, a second embodiment of the method of the present invention is proposed on the basis of the above-described embodiment of the present invention.
This embodiment is a step after step S10 in the first embodiment, and the present embodiment is different from the above-described embodiments of the present invention in that:
and step S40, when it is detected that the weight change exists in the target parking space, acquiring an initial value and an end value of the weight change in a preset time period.
Considering that the vehicle may not be parked well at a time when the vehicle is parked in the target parking space, or the vehicle may not be driven out of the parking space at a time, in this case, the weight change in the target parking space fluctuates, the purpose of introducing the preset time period is to provide a solution when the weight change in the target parking space fluctuates, because the specific time required for the vehicle to drive into the target parking space cannot be known, the preset time period is a relatively long enough time, and the specific time length of the preset time period is not limited and detailed in this embodiment.
In this embodiment, a specific application scenario is given, in which a vehicle owner drives a vehicle to leave a parking space ready for driving, but due to reasons such as unskilled driving technology of the vehicle owner or complex parking situation of a site space, the vehicle owner repeatedly performs forward and backward operations, and finally drives away the parking space thirty seconds after starting the vehicle, and in thirty seconds after starting the vehicle to drive away from the parking space, the weight change in the parking space is fluctuated, in this embodiment, the preset time period may be thirty seconds in the specific application scenario, and the target parking space in this embodiment may be the parking space of the vehicle one in the specific application scenario, then in the specific application scenario, the initial value of the weight change in the target parking space in the preset time period is the weight of the vehicle one, and the end value is the weight value detected by the ground sensing coil sensor when no object exists in the target parking space, may be zero or a sufficiently small value, and the embodiment is not described in detail and limited.
Specifically, the step refined in step S40 further includes:
step a1, when it is detected that there is a weight change in the target parking space, acquiring a maximum value and a minimum value of the weight change in a preset time period.
In this embodiment, the device for detecting the weight in the target parking space is a ground coil sensor, and due to the detection accuracy of the sensor or the ground surface condition of the installation position of the sensor, the weight detected by the ground coil sensor may fluctuate slightly or the weight value detected by the ground coil sensor jumps slightly.
The embodiment provides a specific application scenario, a first vehicle is parked in a roadside parking space, a weight value detected by the ground sensing coil sensor is the weight of the first vehicle, at this time, a pedestrian walks through the roadside and steps on the ground near the parking space to generate vibration, so that the weight value detected by the ground sensing coil sensor may fluctuate slightly, if the first vehicle has a weight of 1500 kg, when the pedestrian walks through the ground near the parking space, the weight value detected by the ground sensing coil sensor rises slightly from 1500 kg, the highest value of the rising is 1502 kg, and after the pedestrian leaves, the gravity value returns to 1500 kg again, the maximum value of the weight change in the preset time period may be 1502 kg in the specific application scenario, and the minimum value may be 1500 kg in the specific application scenario.
Step a2, calculating the difference between the maximum value of the weight change and the minimum value of the weight change, and judging whether the difference is larger than a first preset threshold value.
The first preset threshold in this embodiment is a maximum influence value of an external factor (a factor caused by a vehicle in a non-parking space) on the ground induction coil sensor, which is obtained through a limited number of experiments.
The purpose of calculating the difference between the maximum value and the minimum value of the weight change in the present embodiment and determining whether the difference is greater than the first preset threshold value is to determine whether the factor causing the weight change is related to the vehicle itself.
Step a3, if the difference is greater than the first preset threshold, acquiring an initial value and an end value of the weight change within a preset time period.
It is known that the purpose of calculating the difference between the maximum value and the minimum value of the weight change in the present embodiment and determining whether the difference is greater than the first preset threshold value is to determine whether the factor causing the weight change is related to the vehicle itself. If the difference is greater than the first preset threshold, it is determined that the factor causing the weight change is related to the vehicle itself, in which case the parking space management program will obtain an initial value and an end value of the weight change within a preset time period, and if the difference is less than or equal to the first preset threshold, the parking space management program may not respond.
In step S50, it is determined whether the initial value of the weight change is smaller than the end value of the weight change.
The purpose of determining whether the initial value of the weight change is smaller than the end value of the weight change in this embodiment is to determine a trend of the weight change within a preset time period, and the trend of the weight change can correspond to an action of the vehicle entering or exiting the parking space.
Step S60, if the initial value of the weight change is smaller than the end value of the weight change, it is determined that there is an upward trend of the weight in the target space.
When the initial value of the weight change is smaller than the end value of the weight change, it is determined that there is a trend of weight increase in the target parking space, and there are various reasons for the trend of weight increase in the target parking space.
Step S70, if the initial value of the weight change is greater than the end value of the weight change, determining that there is a weight decreasing trend in the target parking space.
When the initial value of the weight change is greater than the end value of the weight change, it is determined that there is a downward trend of the weight in the target parking space, and there are various reasons for the downward trend of the weight in the target parking space. It is understood that the reason why the start value of the weight change is not equal to the end value of the weight change is that if the start value of the weight change is equal to the end value of the weight change, the concept of the weight change is contradicted.
In the embodiment, the trend of the weight change in the target parking space is determined by judging the sizes of the initial value and the ending value of the weight change in the target parking space within the preset time period, and the action related to the vehicle can be further corresponded according to the trend of the weight change, so that the behavior management of the vehicle in the target parking space is realized.
Further, with reference to fig. 4, a third embodiment of the method of the present invention is proposed on the basis of the above-described embodiment of the present invention.
This embodiment is a step of the first embodiment, which is a refinement of step S20, and the difference between this embodiment and the above-described embodiment of the present invention is:
step S21, when it is detected that there is an ascending trend of the weight in the target parking space, acquiring an initial value of the ascending trend.
This embodiment provides a specific application scenario, as shown in fig. 9, when a vehicle is slowly driven into a parking space at a time when X (X is a coordinate system time axis) is equal to zero, a gravity value Y (Y is a coordinate system weight axis) detected by a ground coil sensor gradually rises, and a Y1 value corresponding to the time when X is equal to zero is that no object is present in the parking space, a weight value detected by the ground coil sensor is a weight value detected by the ground coil sensor, Y1 value is small, when the time axis goes to X1, the vehicle is completely parked in the parking space, and a weight value detected by the ground coil sensor is a sum of the weight of a first vehicle and the weight of an on-board person (corresponding to Y3 value), when the time axis goes to X2, all persons in the first vehicle get off, when the gravity value detected by the ground coil sensor is a weight value of the first vehicle (corresponding to Y2 value), when the time axis goes to X3, the person in the first vehicle returns to the first vehicle, and preparing to drive the vehicle out of the parking space, knowing that the person or the number of persons returning to the vehicle one may not be consistent with the person who gets off the vehicle from X1 to X2, when the time axis goes to X4, the person in the vehicle one returns to the vehicle one, the gravity value detected by the ground coil sensor may be equal to Y3, or may not be equal to Y3 but certainly larger than Y2, when the time axis goes to X5, the weight value detected by the ground coil sensor may be Y1, or may not be Y1 but is not greatly different from Y1 when the vehicle one completely drives out of the parking space.
In the above specific application scenario, the time period in which the rising trend of the weight exists includes 0 to X1 and X3 to X4, and the initial values of the two rising trends are different.
Step S22, determining whether the initial value of the ascending trend is smaller than a second preset threshold.
In this embodiment, the second preset threshold is a maximum gravity value detected by the ground sensing coil sensor in the target parking space without any object in the target parking space under the influence of no external factor, that is, a maximum error of the system, and the purpose of determining whether an initial value of a weight rising trend is smaller than the second preset threshold is to determine a reason causing the weight rising trend, where the reason causing the weight rising trend includes reasons that a vehicle enters the parking space and a person enters the vehicle parked on the parking space.
In step S23, if the initial value of the upward trend is smaller than the second preset threshold, the time when the upward trend is initial is taken as the vehicle entry time.
It is known that the purpose of determining whether the initial value of the weight-increasing tendency is smaller than the second preset threshold value is to determine the reason for causing the weight-increasing tendency, wherein the reason for causing the weight-increasing tendency includes the reasons that the vehicle enters the parking space and the person enters the vehicle parked on the parking space. If the initial value of the ascending trend is smaller than the second preset threshold value, the reason causing the weight ascending trend is judged to be that the vehicle enters the parking space, and in this case, the parking space management program takes the time when the ascending trend is initial as the entry time of the vehicle.
Specifically, the step refined in step S23 further includes:
and b1, if the initial value of the ascending trend is smaller than a second preset threshold, judging whether the ending value of the ascending trend is smaller than a third preset threshold.
It should be understood that the vehicle may not be the vehicle, and other objects such as people, bicycles, electric vehicles, and the like may also enter the target parking space, in this embodiment, the third preset threshold is set according to the weight of the car commonly found on the market at present, the third preset threshold is equal to the weight of the car commonly found on the market at present with the smallest mass, and when the initial value of the ascending trend is smaller than the second preset threshold, the purpose of determining whether the ending value of the ascending trend is smaller than the third preset threshold is to determine whether the object entering the target parking space is the vehicle.
And b2, if the end value of the ascending trend is smaller than the third preset threshold, outputting the occupation violation prompt message.
If the initial value of the ascending trend is smaller than the second preset threshold value and the ending value of the ascending trend is smaller than the third preset threshold value, it is determined that the reason for the ascending trend is that a non-vehicle object enters the target parking space, and in this case, the parking space management program outputs an occupation violation prompt message to prompt the parking space manager that the non-vehicle object may exist in the target parking space. The specific prompt form and prompt content of the default prompt message are not detailed or limited in this embodiment.
Specifically, the step b1, which is refined, further includes:
and c1, if the ending value of the ascending trend is smaller than a third preset threshold, outputting a distance measuring instruction to a distance measuring device which is arranged between two adjacent parking spaces and faces the length direction of the parking space opening to obtain a distance value.
It can be known that, due to the limited urban land resources, parking spaces in the city which are arranged at the roadside are usually closely adjacent, as shown in fig. 8, this embodiment provides a specific application scenario, eight parking spaces are arranged at one section of the roadside, a distance measuring device is arranged between two adjacent parking spaces, and the distance measuring device faces the opening direction of the parking space, i.e., the right direction in fig. 8, it can be known that, in fig. 8, distance measuring devices are also arranged at the lower left corner of parking space 1 and the upper left corner of parking space 8, when a vehicle three and a vehicle four are parked as in fig. 8, parking space 5 (not shown in the figure), the end values of the weight rising trends detected by the ground induction coil sensors in parking space 6 and parking space 7 are both smaller than a third preset threshold, in this case, the parking space management program can also output distance measuring instructions to the distance measuring devices, and it can be assumed that the distance measuring devices are infrared distance measuring devices, and the distance between the infrared distance, as shown in fig. 8, the distance measuring device between space 6 and space 7 can measure the distance between the distance measuring device and the third vehicle.
And c2, judging whether the distance value is smaller than a fourth preset threshold value.
In this embodiment, the fourth preset threshold is set according to the length of an ordinary parking space, and the fourth preset threshold is equal to the length of a parking space, as shown in fig. 8, the fourth preset threshold is equal to the length of a parking space, a distance value measured by a distance measuring device between parking spaces 6 and 7 will be smaller than the fourth preset threshold, and a distance value measured by a distance measuring device between parking space 4 and parking space 5, a distance value measured by a distance measuring device between parking space 5 and parking space 6 will be larger than the fourth preset threshold, and a vehicle occupies two parking spaces due to the fact that the vehicle is parked in an illegal way, and the vehicle is not parked in a parking space completely, and belongs to an illegal parking space.
And c3, if the distance value is smaller than the fourth preset threshold value, outputting vehicle illegal parking prompt information.
Therefore, if the distance value is smaller than the fourth preset threshold, the parking space management program outputs the vehicle illegal parking prompt information to prompt the parking space manager that the vehicle illegal parking phenomenon exists in the parking space, and the specific prompt form and the prompt content of the prompt information are not detailed and limited in this embodiment.
And c4, if the distance value is greater than or equal to the fourth preset threshold, outputting the occupation violation prompt message.
Therefore, if the distance value is greater than or equal to the fourth preset threshold value, the parking space management program outputs the occupation violation prompt information to prompt the parking space management personnel that the occupation violation phenomenon exists in the parking space, and the specific prompt form and the prompt content of the prompt information are not detailed and limited in this embodiment.
And b3, if the end value of the ascending trend is greater than or equal to the third preset threshold, taking the time when the ascending trend is initiated as the vehicle entrance time.
It is noted that, if the initial value of the ascending trend is smaller than the second preset threshold and the ending value of the ascending trend is greater than or equal to the third preset threshold, it may be determined that the cause of the ascending trend is that the vehicle enters the parking space, in which case the parking space management program takes the time when the ascending trend is initial as the entry time of the vehicle.
When the ground induction coil sensor detects that the ascending trend of the weight exists in the preset area, the reason for the ascending trend is determined by judging the initial value and the ending value of the ascending trend, the standard management of the parking space is realized, and a foundation is laid for accurately determining the access time of the vehicle.
Further, with reference to fig. 5, a fourth embodiment of the method of the present invention is proposed on the basis of the third embodiment of the present invention.
This embodiment is a step of the first embodiment, which is a refinement of step S30, and the difference between this embodiment and the above-described embodiment of the present invention is:
step S31, when it is detected that there is a downward trend of the weight in the target parking space, acquiring an end value of the downward trend.
This embodiment provides a specific application scenario, as shown in fig. 9, when a vehicle is slowly driven into a parking space at a time when X (X is a coordinate system time axis) is equal to zero, a gravity value Y (Y is a coordinate system weight axis) detected by a ground coil sensor gradually rises, and a Y1 value corresponding to the time when X is equal to zero is that no object is present in the parking space, a weight value detected by the ground coil sensor is a weight value detected by the ground coil sensor, Y1 value is small, when the time axis goes to X1, the vehicle is completely parked in the parking space, and a weight value detected by the ground coil sensor is a sum of the weight of a first vehicle and the weight of an on-board person (corresponding to Y3 value), when the time axis goes to X2, all persons in the first vehicle get off, when the gravity value detected by the ground coil sensor is a weight value of the first vehicle (corresponding to Y2 value), when the time axis goes to X3, the person in the first vehicle returns to the first vehicle, and preparing to drive the vehicle out of the parking space, knowing that the person or the number of persons returning to the vehicle one may not be consistent with the person who gets off the vehicle from X1 to X2, when the time axis goes to X4, the person in the vehicle one returns to the vehicle one, the gravity value detected by the ground coil sensor may be equal to Y3, or may not be equal to Y3 but certainly larger than Y2, when the time axis goes to X5, the weight value detected by the ground coil sensor may be Y1, or may not be Y1 but is not greatly different from Y1 when the vehicle one completely drives out of the parking space.
In the above specific application scenario, the time periods in which there is a downward trend of the weight include X1 to X2 and X4 to X5, and the end values corresponding to the two downward trends are different.
Step S32, determining whether the ending value of the downward trend is smaller than a second preset threshold.
In this embodiment, the second preset threshold is a maximum gravity value detected by the ground sensing coil sensor in the target parking space without any object in the target parking space under the influence of no external factor, that is, a maximum error of the system, and the purpose of determining whether the end value of the weight decrease trend is smaller than the second preset threshold is to determine the reason causing the weight decrease trend, where the reason causing the weight decrease trend includes reasons that a vehicle exits from the parking space and a person comes out from the vehicle parked on the parking space.
And step S33, if the end value of the downward trend is smaller than the second preset threshold, taking the time when the downward trend ends as the departure time of the vehicle.
It is understood that the purpose of determining whether the ending value of the weight-down tendency is smaller than the second preset threshold value is to determine the reason for causing the weight-down tendency, wherein the reason for causing the weight-down tendency includes reasons that the vehicle is driven out of the parking space and that a person comes out of the vehicle parked on the parking space. If the end value of the descending trend is smaller than the second preset threshold value, the reason causing the weight descending trend is judged to be that the vehicle drives out of the parking space, and in this case, the parking space management program takes the time when the descending trend ends as the departure time of the vehicle.
In this embodiment, when the ground induction coil sensor detects that there is a downward trend of the weight in the preset region, the end value of the downward trend and the second preset threshold are determined, so as to determine the reason for the downward trend, thereby accurately determining the vehicle departure time.
In addition, referring to fig. 6, an embodiment of the present invention further provides a parking space management device, where the parking space management device includes:
the first detection module 10 is used for detecting the weight of the target parking space based on the ground induction coil sensor;
the second detection module 20 is configured to, when it is detected that there is an upward trend of the weight in the target parking space, take time corresponding to the upward trend as entry time of the vehicle;
