Based on the structural block diagram of the terminal, the invention provides various embodiments of the illegal discharging detection method.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the illegal discharging detection method according to the present invention. In this embodiment, the illegal discharging detection method includes the following steps:
step S10, acquiring operation data of a target vehicle-mounted device, wherein the operation data is uploaded by the target vehicle-mounted device and comprises load information and a motion track of the target vehicle-mounted device;
the target vehicle-mounted device is a vehicle-mounted device which has been unloaded but does not check whether the unloading position is located in the target area, that is, the legal unloading area. The operation data are directly obtained by the target vehicle-mounted equipment, and then the obtained operation data are uploaded to the terminal by the target vehicle-mounted equipment, so that the terminal can analyze the operation data of the target vehicle-mounted equipment, and further judge whether the target vehicle-mounted equipment unloads in a target area.
It should be noted that the operation data includes load information and a motion trajectory of the target vehicle-mounted device. It can be understood that the operation data can be obtained by acquiring, by the target vehicle-mounted device, load information and a motion trajectory in the unloading operation process in real time, at regular time or at preset time intervals, where the load information is load data of materials carried by the target vehicle-mounted device in the unloading operation process, the motion trajectory includes, but is not limited to, time points and position information, the time points are time points of the target vehicle-mounted device in the unloading operation process, and each time point corresponds to at least one set of position information and load data. Therefore, the operation data can be generated according to the load information and the position information of the target vehicle-mounted device corresponding to the time point and the time point according to the time sequence from loading the materials to unloading the materials of the target vehicle-mounted device, namely the time sequence of the unloading operation process from the load state to the no-load state. The operation data may be acquired in real time, at regular time or at preset time intervals corresponding to the target vehicle-mounted device, where the time point may be any time point in a persistent time period, may also be each time point set at regular time, and may also be each time point corresponding to a preset time interval based on an initial time point, which is not limited herein. The position information is the position of the target vehicle-mounted device in the discharging operation process, and it is easy to understand that the load data and the position information of the target vehicle-mounted device correspond to different time points in the discharging operation process of the target vehicle-mounted device. It should be noted that the operation data is generated by a preset time sorting mode according to the load data and the position information of the target vehicle-mounted device at the time point and the time point, the preset time sorting mode is a time sequence of the target vehicle-mounted device in the unloading operation process, and optionally, the preset time sorting mode is a time sequence from loading the material to unloading the material of the target vehicle-mounted device.
Step S20, determining target position information of the target vehicle-mounted equipment changed from a load state to an idle state according to the load information and the motion trail;
the operation data corresponding to the target vehicle-mounted equipment is generated according to the time sequence from loading of the target vehicle-mounted equipment to unloading of the materials, namely the time sequence of the unloading operation process from the loading state to the unloading state of the target vehicle-mounted equipment, and the load information and the position information of the target vehicle-mounted equipment are corresponding to the time points and the time points. For example, the operation data records 5 time points according to the unloading time point of the unloading operation process, where the 5 time points are 1, 2, 3, 4, and 5, when the first load data corresponding to the time point 1 is equal to the second load data corresponding to the time point 2, the first load data corresponding to the time point 2 is continuously compared with the second load data corresponding to the time point 3, and when a difference between the first load data corresponding to the time point 2 and the second load data corresponding to the time point 3 is greater than a preset threshold, the position information corresponding to the time point 3 may be determined as the target position information, that is, the unloading position, and so on.
And step S30, determining that the target position information is not in a target area, and outputting abnormal unloading information, wherein the target area is determined by the target position information of a plurality of vehicle-mounted devices.
The target area is a legal unloading area for unloading, and is determined by target position information of a plurality of vehicle-mounted devices. The vehicle-mounted equipment is used for unloading and determining the unloading position. The target position information is unloading position information corresponding to any one of the plurality of vehicle-mounted devices.
And outputting abnormal unloading information when the position information of the target vehicle-mounted equipment changed from the loading state to the no-load state is not in the target area, namely the unloading position of the target vehicle-mounted equipment is an abnormal unloading position. The abnormal unloading information comprises but is not limited to character information, color marking information and symbol marking information, the abnormal unloading information is output to mark the target vehicle-mounted equipment for abnormal unloading, and the abnormal unloading information is helpful for helping a worker or a working unit managing the unloading area to process the vehicle-mounted equipment for illegal unloading. It can be understood that when the unloading position of the target vehicle-mounted device is located in the target area, that is, the normal unloading position, the vehicle-mounted information of the target vehicle-mounted device, such as the license plate number of the target vehicle-mounted device and the driver information corresponding to the target vehicle-mounted device, can be recorded, so that an honest work record file is established for the driver engaged in the unloading work, and the honest work record file is used for evaluating the work attitude and the work quality of the driver.
Optionally, step S30 is followed by:
acquiring the abnormal unloading times of target vehicle-mounted equipment;
and when the abnormal unloading times reach the preset times, marking the target vehicle-mounted equipment as illegal unloading vehicle-mounted equipment.
And the abnormal unloading times are used for recording the times that the unloading position of the target vehicle-mounted equipment is not in the target area. The preset times can be set manually or according to the times limited by official published documents such as illegal discharging specifications, and are not limited. The abnormal unloading times of the target vehicle-mounted equipment can be acquired by presetting an abnormal unloading time identifier to record the abnormal unloading times and then acquiring an identifier value of the abnormal identifier, optionally, the abnormal unloading times of the target vehicle-mounted equipment can be recorded within a preset time length or a preset time period, and when the abnormal unloading times reach the preset times, the target vehicle-mounted equipment is marked as illegal unloading vehicle-mounted equipment, so that the illegal unloading vehicle-mounted equipment can be helped to manage and punish the illegal unloading vehicle-mounted equipment for the serious illegal unloading vehicle-mounted equipment.
In the technical solution disclosed in this embodiment, by obtaining operation data of the target vehicle-mounted device in the unloading operation process, such as load information and a motion trajectory, it is further determined whether target position information of the target vehicle-mounted device for unloading is located in a target area according to the load information and the motion trajectory, that is, it is determined that the target vehicle-mounted device is changed from a load state to an idle state through the load information of the target vehicle-mounted device, that is, an unloading action is performed, and furthermore, it is determined through the motion trajectory that the target position information of the target vehicle-mounted device for executing the unloading action is, when the target position information for executing the unloading action is not in the target area, the target vehicle-mounted device can be considered to perform abnormal unloading, and by outputting abnormal unloading information, a work unit or a worker managing illegal unloading is prompted to quickly know that the target vehicle-mounted device performs illegal unloading, and at the same, in addition, the running data of the target vehicle-mounted equipment for abnormal unloading in the unloading running process is kept as evidence to process the target vehicle-mounted equipment.
A second embodiment of the illegal discharging detection method according to the present invention is provided based on the first embodiment, please refer to fig. 3, and fig. 3 is a flowchart illustrating the illegal discharging detection method according to the second embodiment of the present invention. In this embodiment, step S20 includes:
step S21, sequentially acquiring first load data in the load information and second load data adjacent to the first load data according to the motion trajectory;
step S22, when a difference between the first load data and the second load data is greater than a preset threshold, acquiring position information in the motion trajectory corresponding to the second load data;
in step S23, the position information is determined as the position information of the target vehicle-mounted device changing from the load state to the no-load state.
In an actual application process, in order to definitely determine an abnormal unloading position of a target vehicle-mounted device when the target vehicle-mounted device performs abnormal unloading, uploading operation data in real time or at regular time in an unloading operation process of the target vehicle-mounted device to obtain load information and a motion trajectory of the target vehicle-mounted device, where the operation data is the load information and the position information corresponding to a series of time points and corresponding to each time point in a process of loading materials to unloading materials of the target vehicle-mounted device, where the load information is the load data of the materials carried by the target vehicle-mounted device in the unloading operation process, it is to be noted that the motion trajectory includes the time points and the position information, and each time point corresponds to at least one set of position information and load data, optionally, step S21 includes:
and sequentially acquiring first load data and second load data adjacent to the first load data in the load information according to the time points in the motion trail. It should be noted that the time point is a time point corresponding to the time sequence of the unloading operation process in the unloading operation process of the target vehicle-mounted device.
It is easy to understand that, because the operation data of the target vehicle-mounted device is the load information and the position information recorded in the sequence according to the unloading operation time in the unloading operation process, the time point of the change of the load data can be known through a series of load data recorded in the load information, for example, whether the target vehicle-mounted device is unloaded can be further determined due to the reduction of the load data, and similarly, the position information of the target vehicle-mounted device corresponding to the time point can also be known, for example, the unloading of the target vehicle-mounted device is determined through the change of the load data in the load information, and the unloading position of the target vehicle-mounted device, which is the position information of the target vehicle-mounted device, can be determined through the time point by obtaining the time point corresponding to the change of the load data.
Sequentially acquiring first load data and second load data in the load information according to time points in the motion trail, wherein a time point corresponds to load data, the first load data and the second load data are adjacent to two corresponding time points in the operation data, the time point corresponding to the second load data is later than the time point corresponding to the first load data according to the time point sequence, the load data change time point is determined by comparing the load data corresponding to the adjacent time points recorded on the operation data, it can be understood that when the second load data is smaller than the first load data, the load data is changed, further, when the difference value of the first load data and the second load data is larger than a preset load threshold value, the target vehicle-mounted equipment is abnormally unloaded at the time point corresponding to the second load data, and the position information corresponding to the time point in the motion trail corresponding to the second load data is acquired, the method comprises the steps of determining a specific unloading position of a target vehicle-mounted device, namely determining position information of the target vehicle-mounted device changing from a load state to an idle state. The preset threshold value is the minimum load difference value of the judgment target vehicle-mounted equipment changed from the load state to the no-load state. It is understood that step S20 further includes: and when the second load data is equal to the first load data, namely the target vehicle-mounted device does not unload, continuously acquiring the first load data in the load information and the second load data adjacent to the first load data according to the time points in the motion trail. It should be noted that the first load data and the second load data are not limited to two time points that are fixedly adjacent to each other in the corresponding motion trajectory, and the first load data and the second load data may be any two adjacent time points in the motion trajectory. For example, 5 time points are recorded in the motion trajectory according to the time points in the unloading operation process, where the 5 time points are 1, 2, 3, 4, and 5, when the first load data corresponding to the time point 1 is equal to the second load data corresponding to the time point 2, the first load data corresponding to the time point 2 is continuously compared with the second load data corresponding to the time point 3, and when a difference between the first load data corresponding to the time point 2 and the second load data corresponding to the time point 3 is greater than a preset threshold, the position information corresponding to the time point 3 may be used as the unloading position, and so on.
Optionally, referring to fig. 4, fig. 4 is a schematic flow chart illustrating that the illegal discharging detection method of the present invention confirms the position information in this embodiment, and step S22 includes:
step S221, when a difference value between the first load data and the second load data is larger than a preset threshold value, obtaining a compartment state of the target vehicle-mounted device corresponding to the first load data;
step S222, when the car state is the lifting state, acquiring position information in the motion trajectory corresponding to the second load data.
In the practical application process, when the difference value between the first load data and the second load data is greater than the preset threshold, the target vehicle-mounted device may be a large amount of loaded materials which are dumped when the target vehicle-mounted device is on a downhill slope, or materials which are dumped due to vehicle rollover of the target vehicle-mounted device due to traffic accidents, in order to further confirm whether the target vehicle-mounted device is unloaded, the unloading position of the target vehicle-mounted device may be determined, the carriage state of the target vehicle-mounted device corresponding to the first load data may be obtained, wherein the carriage state may be determined by a sensor which is arranged on the target vehicle-mounted device and is used for detecting carriage lifting, a carriage state identifier may be preset, the identifier value of the carriage state identifier may be set by a signal detected by the sensor for detecting carriage lifting, if the identifier value is "1", the carriage state is a lifting transition state, and if the identifier value is "0", the carriage state is a non-lifting transition state, this is not limitative. It is easy to understand that when the car state is the lifting state, it indicates that the target vehicle-mounted device loaded with the material has a tendency to unload, and further, the second load data is reduced compared with the first load data, and the difference between the first load data and the second load data is greater than the preset threshold, it can be determined that the position information of the motion trajectory corresponding to the second load data is the unloading position information.
In the technical solution disclosed in this embodiment, two adjacent first load data and second load data are sequentially acquired according to a time point in a motion trajectory of a target vehicle-mounted device, when the difference between the first load data and the second load data is not zero, that is, it is determined that the time point at which the load data is changed is the time point corresponding to the second load data, and in addition, when the difference value between the first load data and the second load data is larger than a preset threshold value, the position information of the second load data corresponding to the time point can be determined as the unloading position, wherein, the unloading position is the position information of the target vehicle-mounted equipment changing from the loading state to the unloading state, and further determines whether the target in-vehicle device performs abnormal discharging by determining whether the discharging position is located in the target area, therefore, the running track of the whole unloading running process of the target vehicle-mounted equipment is monitored, and the specific position of the target vehicle-mounted equipment for illegal unloading can be obtained through the unloading position.
A third embodiment of the illegal discharging detection method according to the present invention is provided based on any one of the above embodiments, please refer to fig. 5, and fig. 5 is a flowchart illustrating the illegal discharging detection method according to the third embodiment of the present invention. In this embodiment, step S30 is preceded by:
step S40, acquiring the target position information of each of the plurality of vehicle-mounted devices;
step S50, obtaining distances between the pieces of target position information;
step S60, regarding an area formed by each of the target position information whose distance is less than or equal to a preset distance as the target area.
The plurality of vehicle-mounted devices are vehicle-mounted devices which are unloaded and the unloading positions of which are determined. The target position information is unloading position information corresponding to any one of the plurality of vehicle-mounted devices, wherein the target position information can be represented by a position coordinate point. The target area is a legal unloading area for unloading.
On the premise that the target position information of the plurality of vehicle-mounted devices is determined, the distance between the target position information of each vehicle-mounted device in the plurality of vehicle-mounted devices can be obtained, and the region formed by each target position information with the distance smaller than or equal to the preset distance is divided into target regions to determine a legal unloading region. The distance between the target location information of each vehicle-mounted device may be determined by a distance between the target location information of any two vehicle-mounted devices in the plurality of vehicle-mounted devices, and may be obtained by calculating a distance between location coordinate points of the two vehicle-mounted devices, which is not limited herein. Alternatively, the target area may be determined by performing cluster calculation on target position information corresponding to each of the plurality of vehicle-mounted devices, and it may be understood that a plurality of target areas may be provided, and a vehicle device of the plurality of vehicle-mounted devices whose target position information is not in the target area may be determined as an abnormal vehicle device, and it may be further determined whether the abnormal vehicle device is an illegal discharging device, for example, whether the abnormal vehicle device is due to a dumping of a loaded material occurring in a downhill, or an abnormal vehicle device causes a rollover due to a traffic accident, and the like.
Optionally, step S60 is preceded by:
acquiring the number of vehicle-mounted devices corresponding to the target position information of which the distance is less than or equal to a preset distance;
when the number is greater than the preset number, step S60 is executed, that is, an area formed by each of the target position information whose distance is less than or equal to a preset distance is taken as the target area.
In order to accurately determine the range of a target area and avoid determining only target position information of two vehicle-mounted devices as the target area, when the distance between each piece of target position information is smaller than or equal to a preset distance, the number of the vehicle-mounted devices meeting the preset distance is obtained, namely the number of the vehicle-mounted devices which can be divided into the target area in a plurality of vehicle-mounted devices is determined, and when the number of the vehicle-mounted devices which are divided into the target area is larger than the preset number, namely the number density of the vehicle devices in the same area meets the requirement of forming the target area, the area formed by the target position information of each vehicle-mounted device which is smaller than or equal to the preset distance is determined as the target area, so that the target area is limited. Wherein the preset number is a minimum on-board number of the on-board devices forming the target area.
Compared with the method that the unloading area is determined by adopting the electronic fence, the method that the vehicle-mounted equipment is legally unloaded can be determined only when the vehicle-mounted equipment completely enters the unloading area specified by the electronic fence to unload, the situation that the vehicle-mounted equipment is located outside the unloading area determined by the electronic fence, such as the vehicle-mounted equipment is close to the edge of the unloading area, and the vehicle-mounted equipment dumps the loaded material into the unloading area determined by the electronic fence is ignored, so that the vehicle-mounted equipment is mistakenly considered to be abnormally unloaded. In this embodiment, by obtaining the distance between each piece of target location information in the plurality of pieces of vehicle-mounted equipment, when the distance is less than or equal to the preset distance, and the number of the vehicle-mounted equipment corresponding to each piece of target location information with the distance less than or equal to the preset distance is greater than the preset number, the area formed by the pieces of target location information corresponding to the vehicle-mounted equipment with the distance greater than the preset number can be considered as the target area, i.e., the unloading area, compared with the unloading area determined in the manner of the electronic fence, the determination of the target area in this embodiment can be based on the actually defined unloading area, as long as the distance between the position of the vehicle-mounted equipment in the unloading area and the position of the vehicle-mounted equipment outside the unloading area is less than or equal to the preset distance, the target location information of the vehicle-mounted equipment can be considered to be within the target area, and the situation that the vehicle-mounted equipment which is outside the actual unloading area, particularly close to the edge of the unloading area, unloads the materials is mistaken for abnormal unloading can be avoided. The preset distance can be set manually in advance, the manually preset distance is determined through a large number of distance tests, the obtained maximum distance between the vehicle-mounted equipment which is close to the edge of the unloading area and is used for normally unloading and the vehicle-mounted equipment which is located on the edge of the unloading area is obtained, optionally, the preset distance is smaller than or equal to the maximum distance, it needs to be noted that the vehicle-mounted equipment which is close to the edge of the unloading area and is used for normally unloading is located outside the actual unloading area, and the loaded material is dumped into the vehicle-mounted equipment in the actually determined unloading area.
In addition, in an actual application process, particularly when the target area is not explicitly specified or the target area is specified but the position of the target area is not updated in time, the target area may be determined by obtaining historical operation data of the plurality of vehicle-mounted devices, where, corresponding to the first embodiment, the historical operation data includes load information and a motion trajectory such as time point and position information, where the historical operation data is similar to the definition of the operation data of the target vehicle-mounted device, and details thereof are not repeated.
