Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides an end-to-end whole-course cold chain transportation management platform, which is shown in an embodiment in fig. 1, and comprises a positioning module, a vibration monitoring module, a shooting module, a preprocessing module, a communication module and a management platform;
The positioning module is used for acquiring the position of the refrigerator car;
The vibration detection module is used for acquiring the amplitude of the refrigerator car;
the shooting module is used for acquiring a monitoring video of the cab and transmitting the monitoring video to the preprocessing module;
as shown in fig. 2, the preprocessing module is configured to process the surveillance video as follows, and obtain a processed surveillance video:
calculating the coordinate range of the intercepting area according to the position of the refrigerated vehicle and the amplitude of the refrigerated vehicle;
intercepting video frames in the monitoring video based on the coordinate range to obtain intercepted video frames;
forming a processed monitoring video by all intercepted video frames;
the communication module is used for transmitting the processed monitoring video to the management platform;
the management platform is used for storing and displaying the processed monitoring video.
The invention intercepts the video frames in the monitoring video before uploading the monitoring video to the management platform, thereby greatly reducing the background information contained in the intercepted video, effectively reducing the size of the monitoring video which needs to be uploaded to the management platform while maintaining the effectiveness of the monitoring video, saving the flow, and in addition, in the place with relatively poor network signals, the timely transmission of the monitoring video can still be realized due to the relatively small storage space occupied by the intercepted video frames, so that the management personnel can still find the abnormality of the driver in time.
Specifically, the shooting module may be placed at the rear of the steering wheel to shoot the position of the main driving.
Specifically, the shooting module can take the duration of 10 seconds as the length of the monitoring video, and the video frame of the cab obtained by shooting is transmitted to the preprocessing module in a segmented mode.
Specifically, the refrigerated truck of the invention is directly sent to a receiving party after goods are loaded on the receiving party.
Optionally, the vibration detection module includes an acquisition unit and a filtering unit;
The acquisition unit is used for acquiring the original amplitude of the refrigerator car;
the filtering unit is used for filtering the original amplitude to obtain the amplitude of the refrigerator car.
Specifically, by the filtering process, more accurate amplitude of the refrigerator car can be obtained. Avoiding erroneous amplitudes results in an erroneous increase in the memory space occupied by the processed video.
Specifically, the vibration detection module may include a vibration sensor, where the vibration sensor is configured to obtain a vibration signal of the refrigerated vehicle, and obtain an amplitude of the refrigerated vehicle at each moment through the vibration signal.
Optionally, filtering the original amplitude to obtain an amplitude of the refrigerated vehicle, including:
The original amplitude obtained at time k is denoted by nwampl k, and the process of filtering nwampl k is as follows:
The amplitude coefficient amplcoef of nwampl k is calculated:
wherein H represents a preset positive integer, nwampl s represents an original amplitude obtained at s time;
If amplcoef is greater than the set coefficient threshold, then the filter processing is performed on nwampl k to obtain the amplitude of the refrigerator car by using the following function:
Wherein lwnampl k denotes the amplitude of the refrigerated vehicle obtained by filtering nwampl k, devia denotes the variance of the original amplitude of the acquisition time within the range of the interval k-H, k, devib denotes the variance of the acquisition time,
If amplcoef is smaller than or equal to the set coefficient threshold, filtering nwampl k by adopting a median filter function to obtain the amplitude of the refrigerator car.
In the process of filtering the original amplitude, the invention does not simply adopt a filtering mode for processing, but selects a corresponding filtering mode based on the amplitude coefficient by calculating the amplitude coefficient, so that the filtering processing method can ensure that the accurate amplitude is obtained and simultaneously avoid greatly increasing the time of the filtering processing. This is because, when the amplitude coefficient is larger than the set coefficient threshold, the distribution of the values representing the amplitudes in the vicinity of nwampl k is relatively complicated, and at this time, the present invention performs the filtering process by using the function having the higher filtering capability, thereby ensuring the accuracy of the filtering result. When the amplitude coefficient is smaller than or equal to the set coefficient threshold value, the invention performs filtering processing in a mode of slightly poorer filtering capability, thereby saving the whole filtering time, and ensuring that the invention is in a relatively balanced position between the accuracy of filtering and the time consumption of filtering.
When the above function is used for filtering, the amplitude of the refrigerator car is calculated mainly according to the numerical difference between other original amplitudes and nwampl k and the difference between other original amplitudes and nwampl k in acquisition time. For nwampl s, if the smaller the numerical gap between nwampl s and nwampl k is, and the smaller the difference between nwampl s and nwampl k is, the greater the influence of nwampl s on lwnampl k is, so that lwnampl k of the present invention is more accurate, because the original amplitude with greater reference value is given greater weight. Because the closer the acquisition instants are, the smaller the gap between the original amplitudes, the stronger the correlation between the two original amplitudes.
Specifically, the unit of time here may be milliseconds.
Specifically, when the median filtering algorithm is adopted to carry out filtering processing on nwampl k, the intermediate value of the original amplitude of the acquisition moment within the range of the interval [ k-H, k ] is taken as the amplitude of the refrigerator car.
Optionally, as shown in fig. 3, the device further comprises a prompt module;
When the manager finds that the driver has fatigue driving, the management platform is also used for sending reminding information to the communication module;

And playing a preset prompt record.

The communication module is used for sending the position of the refrigerator car to the management platform;
the management platform is used for displaying the position of the refrigerator car on the map.
Specifically, the frequency of acquiring the position may be the same as the frame rate of the shooting module, that is, if the frame rate is 30 frames/second, the positioning module acquires the position of the refrigerated vehicle 30 times within 1 second.
In particular, a blinking dot may be displayed on the map to indicate the location of the refrigerated truck.
Optionally, the vibration detection module is further configured to send the amplitude of the refrigerated vehicle to the communication module;
the communication module is used for sending the amplitude of the refrigerated truck to the management platform;

The management platform is used for displaying carriage information.
Specifically, the cabin information includes temperature, humidity, and the like.
Optionally, the system further comprises a client module;
The management platform is used for sending the position of the refrigerated vehicle and carriage information to the client module;
the client module is used for displaying the position of the refrigerator car and carriage information.
Specifically, the user of the client module is a shipping client and a receiving client. In the process of end-to-end delivery of the refrigerated truck, a customer can view the position of the refrigerated truck and the carriage state of the refrigerated truck in real time through the client module.
Optionally, calculating the coordinate range of the intercepting area according to the position of the refrigerated truck and the amplitude of the refrigerated truck includes:
acquiring original parameters of the intercepting area according to the position of the refrigerated truck;
And calculating the coordinate range of the intercepting region based on the original parameters and the amplitude of the refrigerated truck.
In particular, the original parameters are obtained according to the location class because the maximum values of the amplitudes of the refrigerated vehicle on different types of roads are different, and if the same type of original parameters are used on all roads, a single type of original parameters are difficult to be used on different types of roads, so that the obtained intercepted video frames may result in an incomplete area where the driver is located. Therefore, the arrangement mode of the invention can well avoid the occurrence of the situation. The quality of the processed monitoring video sent to the management platform is improved, and the manager can find the abnormality of the driver in time.
Optionally, acquiring the original parameters of the interception area according to the position of the refrigerator car includes:
Judging the type of a road where the refrigerated vehicle is located according to the position of the refrigerated vehicle;
and obtaining the original parameters of the interception area according to the type.
Specifically, the location ranges of the different types of roads may be stored in advance, and then the type of road on which the refrigerated vehicle is located can be determined according to whether the location of the refrigerated vehicle is located in the location range.
Alternatively, the type is expressway or primary road or secondary road or tertiary road or quaternary road;
each type of road corresponds to an original parameter of one type of intercepting region;
the original parameters of the intercepting region comprise the length and the width of the preset intercepting region.
Specifically, the lower the construction standard of the road is, the greater the length and width of the preset intercepting region are, because the lower the construction standard of the road is, the greater the variation range of the amplitude is when the refrigerated vehicle runs on the road, so that the driver can be ensured to be completely in the intercepted video frame by correspondingly increasing the length and width of the preset intercepting region.
Here, the length refers to the number of pixels in the horizontal direction of the cut-out region, and the width refers to the number of pixels in the vertical direction.
Optionally, calculating the coordinate range of the intercepting region based on the original parameters and the amplitude of the refrigerated vehicle includes:
A is used for indicating the type of a road where the refrigerated vehicle is located; oriwid A and orileth A are used for representing the width and length of a intercepting area corresponding to a preset road of the type A; the coordinates of the center of the preset intercepting region are represented by (x mid,ymid); a vidfra t is used for representing a video frame obtained at the time t; the amplitude of the refrigerated truck at the time t is denoted by amplti t;
the process of acquiring the coordinate range of the intercepting region corresponding to vidfra t is as follows:
The width areawid t of the interception area is calculated:
Solving the length arealeth t of the interception area:
stramplti denotes a preset amplitude;
The coordinate range of the intercepting region is as follows:
In the invention, after the original parameters are obtained, the adaptive change of the range of the intercepted area can be realized only by calculating according to the same amplitude as the acquisition time of the video frame, and the driver is ensured to be in the intercepted video frame. When the amplitude is larger, the area of the intercepting region is larger, and the change amplitude of the intercepting region is positively correlated with the amplitude, so that the size of the intercepting region is effectively controlled while a driver is ensured to be in an intercepted video frame, and the volume of the processed monitoring video is effectively reduced.
Specifically, the coordinates of the center of the preset intercepting area may be the coordinates of the center point of the backrest of the main driving seat in the video frame, which is shot by the shooting module, when the refrigerated vehicle is stationary.
Optionally, capturing a video frame in the monitoring video based on the coordinate range to obtain a captured video frame, including:
and deleting the pixel points which are positioned outside the coordinate range of the intercepting region in the video frame, thereby obtaining the intercepted video frame.

The preferred embodiments are not exhaustive or to limit the invention to the precise form disclosed. Obviously, many modifications and variations are possible in light of the above teaching.
