s1, monitoring the customs lock and acquiring the transportation state information of the customs lock.
The customs lock used in this embodiment is an intelligent customs lock, and as shown in fig. 2, the customs lock has modules such as a main control module, a switch lock module, a video module, a 4G/5G module, a WiFi module, a sensor module, an RFID module, a PIR detection module, a GPS module, and a bluetooth module, wherein the main control module is connected with other modules, receives information acquired or acquired by other modules, and processes the information. The intelligent customs lock is in communication connection with the cloud platform, the cloud platform is in communication connection with the user terminal, and the user can log in the cloud platform through the mobile terminal used by the user to check transportation state information of the customs lock corresponding to the user terminal. In one embodiment, real-time video stream pushing is performed between the cloud platform and the mobile terminal of the user through rtmp. The user can also send a control instruction for the customs lock through the mobile terminal, and the video module of the customs lock is controlled to start to collect the video, so that the user can check the video monitoring information acquired by the video module of the current customs lock on the cloud platform.
In one embodiment, the mobile terminal of the user may install an application program that is specially used for checking and controlling the transportation state information of the customs lock, after the user downloads and installs the application program, when logging in the application program, the mobile phone number is bound with the customs lock, after the binding is completed, the cloud platform pushes the information of the bound customs lock to the user terminal, and the user terminal can check the relevant information of the customs lock through the application program, for example: the current position, the historical transportation track, the current state of the switch lock, whether the switch lock is in the unlocking state or the locking state and the like.
In this embodiment, because the cloud platform needs to acquire the transportation state information of the customs lock, communication connection is first established between the customs lock and the cloud platform, the cloud platform can acquire the position information of the customs lock and obtain the transportation route of the customs lock according to the position information of the customs lock, and then the customs lock further has a video shooting function, the cloud platform can control the video shooting function of opening or closing the customs lock, and particularly when the cloud platform monitors that the customs lock transportation route is abnormal or the unlocking time is abnormal, the cloud platform controls the camera function of the customs lock to be opened, so that the transportation image in an abnormal period is acquired, and a user can know the conditions of articles more clearly.
The transportation state information includes: the sensor module collects motion state data information, locking and unlocking state information, real-time and historical positioning information, transportation track information and transportation time information. The sensor module can acquire the acceleration data of the current customs lock, and the PIR detection module can acquire corresponding motion detection data, so that whether the current vehicle is in driving and whether a collision event occurs can be identified. The data acquired by the GPS positioning module is generally longitude and latitude information, so that real-time and historical position information can be obtained by combining the longitude and latitude information positioned in continuous time with a route of a map.
Because the customs lock has functional modules such as video, communication and sensors, the cloud platform can monitor the customs lock, acquire real-time state information of the customs lock, namely equipment state information of the customs lock, and further analyze the situation of the customs lock according to the equipment state information of the customs lock.
Specifically, the step of monitoring the customs lock and acquiring the transportation state information of the customs lock includes:
and S11, establishing communication connection between the customs lock and the cloud platform.
Because the cloud platform needs to monitor the customs lock in real time, acquire the equipment state information of the customs lock, therefore at first need establish communication connection between customs lock and the cloud platform, as shown in fig. 2, because the customs lock is based on 4G or 5G module, also have the WIFI module simultaneously, bluetooth module so communication connection between cloud platform and the customs lock can be 4G or 5G communication connection, also can be wireless WIFI connection, after establishing communication connection, the cloud platform can acquire the motion data that the sensor module of customs lock gathered, the position data of customs lock that the GPS module was fixed a position, and information such as video data that video module shot.
And S12, judging whether the cloud platform acquires the transportation state information of the customs lock.
And after the communication is established, judging whether the cloud platform can normally acquire the transportation state information of the customs lock. And if one or more of the data information can not be normally acquired, the data information is fed back to the cloud platform and displayed on the cloud platform, so that a user can timely know the data information and maintain or replace the module which can not be normally used.
And S13, if the transportation state information of the customs lock cannot be acquired, acquiring the video monitoring information of the customs lock.
If the transport state information of the customs lock is acquired, whether the video monitoring information acquired by the video module can be normally acquired is judged, if the video monitoring information cannot be acquired, the video monitoring information needs to be fed back to acquire the abnormity, so that a user can timely maintain the abnormity, if the transport state information of the customs lock cannot be acquired, the video monitoring information acquired by the video module is tried to be acquired, if the video monitoring information acquired by the video module can be normally acquired, the video monitoring information of the current customs lock is acquired, and the video monitoring information is pushed to a cloud platform.
And S14, displaying the video monitoring information through a display screen.
If the transportation state information is not acquired normally, the cloud platform pushes the received transportation state information to a display screen of the cloud platform for displaying, so that a user can know the current state of the customs lock.
And S2, identifying the vehicle transportation state and the vehicle position of the transported goods according to the transportation state information.
The cloud platform analyzes the current transportation state of the article according to the acquired transportation state information, positions the position of the current article and acquires a track route of the article in the transportation process.
After the positioning information of the article is acquired, whether the current article is abnormal or not in the transportation process can be judged according to the positioning information and the transportation track information, and the abnormal condition comprises the following steps: whether the transportation route deviates, whether the transportation route arrives at the designated place earlier than the preset time or later than the preset time, whether a collision event occurs, whether the time and place for opening and closing the lock are normal, and the like.
Specifically, the step of classifying the transportation state of the transported item according to the device state information includes:
obtaining transportation track information according to the real-time positioning information and the historical positioning information;
determining one or more transport track points according to the transport track information;
combining the transportation track information, each transportation track point, and the running state information and the transportation time information corresponding to each transportation track point to construct a transportation state diagram;
and comparing the transportation state diagram with the preset transportation planning diagram, and identifying to obtain the current vehicle transportation state and the deviation information of the vehicle position point and the preset planning position point.
Firstly, a user sets a preset planning route, a preset planning area and a preset transportation planning time range according to an article transportation destination. Specifically, the preset planned route may be a plurality of latitude and longitude location points in the marine channel through which the article transportation is expected to pass. The preset planning area is an area range which is drawn by taking a plurality of longitude and latitude position points in the preset planning route as central points and taking the preset length as a radius. The preset planning time range is a time range which is set according to the departure time of the preset flight and the time range which is set according to the arrival destination and is possible to arrive at each longitude and latitude position point. And then, a preset transportation planning map is made according to the information of the preset planning route, the preset planning area, the preset transportation planning time range and the like.
In one embodiment, the real-time positioning information and the historical positioning information of the current customs lock are obtained from a GPS positioning module of the customs lock, and the transportation track information of the current customs lock is obtained according to the positioning information. And determining each transport track point passed by the vehicle corresponding to the customs lock according to the transport track information, wherein the transport track point is each passing stop point or the place of the important traffic main road. And deriving a corresponding transportation track point list according to the transportation track information.
And marking the transportation track points into the transportation track, and marking the transportation state of the vehicle corresponding to each transportation track point and the arrival and departure time points into the transportation track route at the same time to obtain a transportation state diagram.
The transportation state diagram obtained in real time is compared with a transportation planning diagram generated in advance, so that the current vehicle transportation state and the deviation information of the vehicle can be obtained through analysis, and whether an abnormal event occurs during transportation is judged.
Specifically, when the abnormal event is judged, the trip condition of the currently-operated flight needs to be comprehensively considered, the weather state of the current day is considered, whether the currently-operated flight is cancelled or not is judged, if the flight is cancelled, the transportation time may be abnormal, and therefore when the abnormal event alarm is sent, whether the current state is caused by other time needs to be judged according to specific conditions.
And judging whether the transportation route is abnormal or not according to the transportation track, if the transportation track is deviated, judging whether the transportation track exceeds a preset planning area, and if the transportation track exceeds the preset planning area, judging that the transportation has an abnormal event on the transportation route.
Further, whether the transportation time is abnormal or not is judged, and if the transportation place is earlier than the preset time point or later than the preset time point, the transportation time is judged to be abnormal. The exception event types thus mainly include: a route exception event and a time exception event; the step of judging the type of the abnormal event if the abnormal event occurs comprises the following steps:
if the current transportation route deviates from the preset planning area and the current position exceeds the preset planning area, judging that the current transportation route is a route abnormal event;
further, according to whether the preset transportation time corresponding to the position of the current article exceeds the preset transportation planning time range or not, if the preset transportation time exceeds the preset transportation planning time range, the time abnormal event is judged.
In order to more accurately judge the transportation abnormal event, the step of judging whether the transportation route deviates from a preset planned route according to the transportation track information comprises the following steps:
acquiring the transportation track information according to historical positioning information and real-time positioning information;
comparing the transportation track information with a preset planned route, and judging whether the contact ratio is lower than a preset threshold value; if the current position is lower than the preset planned route, judging that the transportation route deviates from the preset planned route;
if the real-time positioning information is higher than or equal to the preset planning time range, whether the preset transportation reaching time corresponding to the real-time positioning information is within the preset planning time range is obtained;
and if the route exceeds the preset planning route, deviating the transportation route from the preset planning route.
Further, in order to more accurately determine a time abnormal event, the step of determining that the time abnormal event is a time abnormal event further includes:
judging whether the arrival time of the current position of the article is earlier than or later than the preset planning time according to the real-time position information and the preset transportation planning time;
if the current position is earlier than the preset planning time, judging whether the difference value between the current position arrival time and the preset planning time exceeds a preset time threshold value, and if so, sending an early warning;
if the time is later than the preset planning time, whether the difference value between the arrival time of the current position and the preset planning time exceeds a preset time threshold value or not is judged, and if the difference value exceeds the preset time threshold value, a late alarm is sent out.
When the exceeding time of the transportation time earlier or later than the preset time point is within an acceptable time range, judging that the current time is abnormal and is in a normal condition, otherwise, judging that the time is an abnormal event.
Because an abnormal unlocking event can also occur in the transportation process of the article, the article positioning and tracking method further comprises the following steps:
monitoring the on-off state of the customs lock in the transportation process, and if an unlocking event occurs, acquiring the information of the position where the unlocking is positioned;
judging whether the customs lock is in a free locking and unlocking area or not according to the position information;
and if the customs lock is not in the free locking and unlocking area, an unlocking abnormity alarm is sent out.
In one embodiment, a user firstly defines a free switching lock area according to a running route, and specifically, when defining the free switching lock area, the area in a preset range at a position point of a customs level where an article passes and the area near the position point are both considered as the free switching lock area, and other areas are judged as non-free switching lock areas. The unlocking state of the sea lock is monitored, whether the unlocking time or the locking time or the unlocking place of the sea lock is in a free locking and unlocking area or not is judged, if yes, the current object is in a safe state, and otherwise, the unlocking or the locking in the transportation process belongs to an abnormal condition.
Further, the article location tracking method further includes:
timing the parking time of the customs lock in the transportation process, and judging whether the parking time exceeds a preset parking threshold value;
if the vehicle speed exceeds the preset threshold value, an overtime parking alarm is given out.
In the transportation process, the stopping time of the articles is timed, whether the stopping time exceeds a preset time range or not is judged, if yes, an overtime parking alarm needs to be sent out, and whether the current articles are safe or not is known by a user.
And S3, obtaining the position positioning tracking information of the transported goods according to the vehicle transportation state and the position positioning identification result.
Further, in order to make a further accuracy judgment on the abnormal condition, the article location tracking method further includes:
identifying monitoring video information corresponding to the current abnormal event according to the real-time position information of the article;
and judging whether the current abnormal event is consistent with the type of the abnormal event or not, and displaying the judgment result.
The user can further judge the type of the abnormal event obtained by alarming through the video information uploaded to the cloud platform, and meanwhile, whether the alarm system is normal or not is also identified.
In order to realize timely understanding of the user on the abnormal event, after the abnormal event occurs, the cloud platform timely acquires monitoring video information obtained by shooting by a camera of the customs lock and plays the monitoring video information, so that the user can judge the reason of the occurrence of the current abnormal event at the first time and judge whether the abnormal event is caused by other reasons, for example: whether the flight is cancelled, delayed and the like due to weather reasons or not, so that the safety of the goods is ensured.
The step of obtaining the position location tracking information of the transported goods according to the vehicle transportation state and the position location identification result comprises the following steps:
and judging whether the current vehicle transportation is in a normal transportation range and a stop point with the nearest distance from the current vehicle according to the current vehicle transportation state and the deviation information of the vehicle position point and the preset planning position.
In order to facilitate the user to know the transportation situation of the current item in real time, the method further comprises the following steps:
receiving a video-on-demand instruction of a user, controlling a customhouse lock camera to start and shooting a current transportation monitoring video;
and pushing the current transportation monitoring video to a display screen for display.
If the camera module of the customs lock is always in a shooting state, the first time is relatively power-consuming, and the second time is required to store and transmit a video file with a larger memory, so that in specific implementation, the video module can be started to acquire a current transport video when needed, for example, when an abnormal event possibly occurs or a user sends a video-on-demand instruction and checks the transport condition of an article, and when no abnormality occurs, the video module can be controlled to be in a dormant state so as to save electric quantity and reduce unnecessary memory occupation.
Specifically, the user can send a video-on-demand instruction through the mobile terminal, the cloud platform controls the customs lock to open the camera to shoot a current video picture, and transmits the current video picture to the cloud platform, so that the user can view the shot video played and displayed on the display screen of the cloud platform through the mobile terminal.
In order to obtain complete transportation state information, the method further comprises:
monitoring whether the communication connection with the customs lock is interrupted;
and if the communication connection interruption event occurs, acquiring the vehicle transportation state information within the communication connection interruption time, and fusing the vehicle transportation state information within the interruption time with the vehicle transportation state acquired historically to obtain continuous vehicle transportation state information in the transportation process.
During specific implementation, if communication interruption occurs, the cloud platform cannot timely receive the transmitted data information from the customs lock, and therefore after communication connection is successful, data in interruption time needs to be packaged and transmitted to the cloud platform, so that the cloud platform obtains complete data, and a complete transportation track route of the vehicle during transportation is identified and obtained.
Further, the step of combining the transportation track information, each transportation track point, the running state information corresponding to each transportation track point and the transportation time information to construct the transportation state diagram comprises:
marking each transportation track point on the transportation track in the transportation track information;
