Detailed Description
The present application is described in further detail below with reference to figures 1-11.
The embodiment of the application discloses a container overturning detection method.
Referring to fig. 1, the turnover detection method of the cargo box includes:
s1: acquiring the label content of the RFID label;
s2: recording the time for acquiring the label content to generate recording time;
s3: acquiring position information of the container;
s4: recording the time for acquiring the position information, and generating position time;
s5: comparing the recording time with the position time to obtain a comparison result;
s6: and when the comparison result is successful, outputting the position information.
Particularly, an eccentric wheel is connected in the container in a rotating mode, and an RFID label 8 is fixedly connected to one side of the eccentric wheel. When not overturning, the tag is far away from the reader 9 and can not be effectively read, after overturning, the distance is close, and effective reading can be realized, wherein the reader 9 can be arranged at a corresponding position corresponding to the bottom of the box body and on the surface of the transport vehicle or in the deck of the transport ship body. In another embodiment, a second RFID tag 8 is fixedly connected to the bottom surface of the container, or when the container is placed right, the two RFID tags are close to each other, at this time, because the two RFID tags 8 interfere with each other, the reader 9 cannot effectively read the contents of the tags, and after the tags on the eccentric wheel rotate along with the eccentric wheel, the reader 9 can read the contents of the tags on the eccentric wheel.
Wherein the label contents can be accessed when the container is inverted. Specifically, after the container is turned upside down to form an upside-down state, the label content of the RFID label 8 is acquired, and then the time for acquiring the label content is recorded while the label content is acquired, so that the recording time is generated.
It will be appreciated that containers are generally large and therefore generally will not tumble during transport, and therefore inversion of containers will generally occur during loading and unloading, i.e. at the discharge or loading point, where positional information is obtained, i.e. whether the container is located at the loading or discharge point. And recording the time for acquiring the position information while acquiring the position information, and generating the position time, thereby recording the time for positioning the container at a loading point or a unloading point.
Then, the recording time is compared with the position time, and a comparison result is obtained. And outputting the position information when the comparison result is successful. Wherein, the contrast result indicates for succeeding in, and the record time has the time point of coincidence with the position time, and the position information that corresponds with the position time of output this moment just can judge that the packing box is in the loading point or the unloading point has been invertd to can decide responsibility to corresponding loading personnel or navigating mate. When the comparison is unsuccessful, the situation that the container is inverted is judged to be an objective factor, and the responsibility of the cargo loader is not followed. Therefore, by the method, whether the goods are inverted in the carrying process can be judged accurately, and the reason why the goods are damaged can be found accurately.
Referring to fig. 2, as an alternative implementation manner of this embodiment, when the comparison result is successful, the step S6 of outputting the position information includes the following steps:
s61: recording the duration of obtaining the label content, and generating the label duration;
s62: when the recording time is matched with the position time, acquiring corresponding tag duration;
s63: comparing the tag duration to a time threshold;
s64: when the tag duration is greater than or equal to the time threshold, the location information is output.
Specifically, after the label content of the RFID label 8 is acquired, the duration of one inversion process of the container, that is, the duration of acquiring the label content, may be recorded, specifically, the time when the container starts to be inverted is recorded, then the time when the container is placed right, that is, the time when the label content is not read is recorded, and the label duration is acquired according to the difference between the inversion time and the right placement time.
When the recording time matches the location time, the corresponding tag duration is acquired at this time. That is, when the recording time matches the position time, the time when the recorded container starts to be inverted is the recording time, and the label duration acquired at this time corresponds to the recording time at this time, so that the position information corresponding to the recording time at this time is the position information corresponding to the label duration at this time.
The tag duration is then compared to a time threshold to determine whether the damage to the good is due to the good being inverted for a long period of time. If the tag duration is greater than or equal to the time threshold, it is determined that the damage to the good is due to being inverted for a long time, otherwise it is not. For example, the tag duration is 60 minutes, and the time threshold is 40 minutes, then it can be determined that the goods damage is caused by human subjective factors, and therefore, the responsibility determination can be made. When the human responsibility is confirmed, the position information at the moment is output, so that the position of the discharging point or the charging point at the moment can be acquired, and further, the worker can be judged to load or unload the goods according to the position at the moment, so that the responsibility can be embodied to the individual, and the accuracy of responsibility judgment can be improved.
Referring to fig. 3, as an alternative implementation manner of this embodiment, in step S5, comparing the recording time with the position time, and obtaining the comparison result includes the following steps:
s51: obtaining the staying time of the position information;
s52: obtaining a departure time based on the dwell time;
s53: judging whether the recording time is between the position time and the leaving time;
s54: if yes, the comparison is successful;
s55: if not, the comparison is unsuccessful.
Specifically, in order to improve the probability of successful comparison between the recorded time and the position time and further improve the accuracy of judgment, the stop time of the position information, namely the stop time of the container after the container enters the loading point or the unloading point, is firstly obtained, and then the leaving time is obtained according to the stop time. For example, the time for a container to enter the loading point or to be unloaded, i.e. the location time is 9 hours and 20 minutes, and the residence time is 60 minutes, and the departure time is 10 hours and 20 minutes.
At the moment, whether the recorded time is between the position time and the leaving time is judged, for example, when the recorded time is 10, the recorded time can be judged to be between the position time and the leaving time, then the comparison is successful, the situation that the container is inverted to occur at a discharging point or a charging point can be judged, then the inquiry and responsibility tracing can be carried out on corresponding personnel, and when the recorded time is not between the position time and the leaving time, namely the matching is unsuccessful, the situation that the container is inverted to be a non-subjective human factor can be judged, and the responsibility can be avoided as appropriate.
By judging whether the recording time is between the position time and the leaving time, the probability of successful matching can be improved, and the possibility of unsuccessful matching caused by point-to-point matching is reduced, so that the accuracy of responsibility judgment can be further improved, and the possibility of disputes can be reduced.
Referring to fig. 4, as an alternative implementation manner of this embodiment, the method for detecting the tipping of the cargo box further includes:
s10: recording the times of obtaining the label content based on the same position information, and generating the turnover times;
s11: acquiring the turnover times corresponding to different position information;
s12: comparing all the turnover times with a time threshold;
s13: and when the turnover frequency is more than or equal to the frequency threshold value, acquiring the position information corresponding to the turnover frequency.
Specifically, the times of reading the label contents of the same container at the same position are recorded, namely the times of turning the same container at the same loading point or unloading point are recorded, the label contents are acquired once the container is turned upside down, and the turning times are generated according to the acquired times of the label contents.
Then, the turning times of the same container in different positions are recorded, and finally all the turning times are compared with a time threshold value, wherein the time threshold value is set according to different goods, for example, the set different times are set according to different goods, for example, the time threshold value of some goods is zero, namely the goods can be damaged only by being turned upside down, and the threshold value of some times is set to be a positive integer of 1, 2, 3 and the like. When the turnover frequency is more than or equal to the frequency threshold value, the position information corresponding to all turnover frequencies larger than the frequency threshold value is obtained, so that the situation that the goods are inverted at which loading station or unloading station can be determined, corresponding personnel at all corresponding positions can be subjected to responsibility tracing, and the accuracy of judging the person responsible for goods damage is further improved.
Further, referring to fig. 5, on the basis of determining the turnover number and the threshold value of the turnover number, the turnover detection method of the container further includes:
s20: acquiring all turnover times larger than a time threshold;
s21: sorting all the turnover times larger than a time threshold value based on the priority of the turnover times to obtain a sorted list;
s22: and sequentially acquiring corresponding position information based on the turning times in the sorted list.
Specifically, all the turning times larger than the time threshold are obtained first, then all the obtained turning times are sorted according to the turning times, the sorting mode can be from large to small or from small to large, and a sorted list is obtained after the sorting is completed. And the sorted list comprises all the turnover times which are greater than the time threshold, and then the position information corresponding to the corresponding turnover times is sequentially acquired according to the sorted turnover times. According to the mode, the damage degrees of the goods can be sequenced according to different overturning times of different positions, the larger the overturning times of the positions are, the larger the damage degree of the goods is, the larger the responsibility of the personnel at the corresponding positions is, so that the responsibility can be divided according to the mode, and the responsibility division is more reasonable.
Further, referring to fig. 6, in another optional implementation manner of this embodiment, on the basis of determining the turnover number and the threshold value of the turnover number, the method for detecting the turnover of the cargo box further includes:
s30: acquiring a moving path of the container;
s31: sequencing all position information based on the moving path to obtain a position list;
s32: acquiring position information corresponding to all turnover times larger than a time threshold value, and generating a path position;
s33: position information corresponding to the path position is sequentially acquired based on the position list.
Specifically, a travel path of the truck, that is, a movement path of the cargo box is acquired according to the GPS navigation system. It is to be understood that the movement path includes all the position information. And then sorting all the position information according to the moving direction of the containers according to the moving path so as to obtain a position list.
And then according to all the turnover times larger than the time threshold, obtaining the position information corresponding to the turnover times, thereby generating the path position. And finally, according to the path positions, sequentially acquiring the position information corresponding to all the path positions from the position list according to the sequence of the position information in the position list. Therefore, the damage of the container can be judged to be serious gradually according to the moving direction of the container, and then the damage degree of the cargo can be judged according to the moving path, so that the responsibility judgment is carried out.
Referring to fig. 7, as an alternative implementation manner of this embodiment, the method for detecting the tipping of the cargo box further includes:
s40: acquiring the vibration amplitude of the RFID tag 8;
s41: acquiring position information corresponding to the vibration amplitude;
s42: comparing the vibration amplitude with an amplitude threshold;
s43: and when the vibration amplitude is greater than or equal to the amplitude threshold value, outputting the position information.
Specifically, the damage of the cargo may also be caused by being subjected to vibration, and therefore the vibration amplitude of the RFID tag 8 is acquired, so that the vibration amplitude of the cargo box can be acquired, and then the position information corresponding to the vibration amplitude, that is, the position information when the cargo box is subjected to vibration, is acquired. And then comparing the vibration amplitude with an amplitude threshold value, and outputting the position information at the moment when the vibration amplitude is greater than the amplitude threshold value.
The amplitude that the biggest vibration that the goods can bear caused is set up to the range threshold value, if vibration amplitude is greater than the range threshold value, explains that the vibration that the goods received has surpassed the biggest scope that the goods can bear, consequently can cause the damage of goods, and the impaired position of goods just can be judged to output position information this moment to tracing for accountability to corresponding personnel.
The label content comprises a label number, and the label number can be acquired while the label content is acquired, so that the container can be conveniently distinguished, and the position judgment accuracy is improved.
The implementation principle of the turnover detection method for the container in the embodiment of the application is as follows: when the container is inverted, the label content of the RFID label 8 is obtained, at the moment, the container can be determined to be inverted, the time for obtaining the label content is recorded while the label content is obtained, the recording time is generated, the position information of the container is obtained, the time for obtaining the position information is recorded, the position time is generated, the recording time and the position time are compared, a comparison result is obtained, and when the comparison result is successful, the position information which is successfully compared is output. Whether the goods are inverted in the carrying process can be accurately judged, and therefore the damaged reasons of the goods can be accurately found.
The embodiment of the application also discloses a turnover detection controller of the container.
The turnover detection controller of the container comprises:
a memory storing an intelligent detection program;
and the processor can execute the steps of the turnover detection method of the container when running the intelligent detection program.
The embodiment of the application also discloses a turnover detection system of the container.
Referring to fig. 8 and 9, the turnover detecting system of the container includes:
the tag obtaining module 1 is used for obtaining tag contents of the RFID tag 8;
the tag time recording module 2 is used for recording the time for acquiring the tag content and generating recording time;
the position acquisition module 3 is used for acquiring the position information of the container;
the position time recording module 4 is used for recording the time for acquiring the position information and generating the position time;
the time matching module 5 is used for comparing the recorded time with the position time and obtaining a comparison result;
and the position output module 6 is used for receiving the comparison result and outputting the position information.
Specifically, referring to fig. 10, a connecting rod is fixedly connected to the inner side wall of the container vertically, an eccentric 7 is fixedly connected to the connecting rod, an RFID tag 8 is fixedly connected to one side of the eccentric 7 away from an eccentric hole of the eccentric 7, when the container is placed right side, the RFID tag 8 faces the bottom surface of the container, a reader 9 is fixed to the top surface of the container, and at this time, the reader 9 cannot read the tag content of the RFID tag 8 located on the eccentric 7.
Referring to fig. 11, when the cargo box is inverted, the eccentric 7 is deflected, the RFID tag on the eccentric 7 can approach the reader 9, and the RFID tag 8 can be read by the reader 9, so that the tag content can be obtained.
In another embodiment, a second RFID tag 8 is fixedly connected to the bottom surface of the container, or when the container is placed right, the two RFID tags are close to each other, at this time, because the two RFID tags 8 interfere with each other, the reader 9 cannot effectively read the contents of the tags, and after the tags on the eccentric wheel rotate along with the eccentric wheel, the reader 9 can read the contents of the tags on the eccentric wheel. For ease of understanding, the label on the underside of the container is marked 81 and the label on the eccentric 7 is marked 82.
While the tag obtaining module 1, that is, the reader 9 obtains the tag content, the tag time recording module 2 records the time of obtaining the tag content and generates a recording time. Meanwhile, the position acquisition module 3 acquires the position information of the container, and the position time recording module 4 records the time for acquiring the position information while acquiring the position information, so as to generate the position time.
