Description
Technical Field
The invention relates to the field of detection data processing, in particular to a processing method, a processing device and a detection system capable of automatically associating acquired data.
Background
In a detection channel such as a container or an automobile, a plurality of data acquisition devices are arranged to acquire data of the equipment to be detected passing through the detection channel, and then the data acquired by the data acquisition devices are associated with the equipment to be detected.
In the prior art, a set of lever devices is usually disposed at the entrance and exit positions of the detection passage, i.e., the positions where the device to be detected (such as a vehicle, etc.) enters and leaves. When the equipment to be detected reaches the front stop lever, the front stop lever is lifted, and the equipment to be detected drives into the channel; the equipment to be detected continuously advances, and each data acquisition equipment is triggered to acquire data, and each data acquisition equipment comprises: license Plate Recognition (LPR) equipment, Container number Recognition (CCR) device, Radioactive Monitoring system (RM) device, wagon balance (or ground coil), chassis Recognition system, radiation imaging inspection equipment, and the like; when the equipment to be detected arrives at the rear gear lever, the rear gear lever is lifted, and the equipment to be detected drives away from the detection channel. Because before the rear gear lever is lifted, the front gear lever can not be lifted, and only one device to be detected is ensured to be detected in the detection channel. And the background processing device is used for putting all the acquired data in the period of time that the two side gear rods are lifted up together as the data corresponding to the equipment to be detected.
Another common method may not be to provide a blocking lever, and a plurality of data acquisition devices sequentially acquire and record data of the device to be detected when the device to be detected passes through the detection channel, so as to receive the last data acquisition device (for example, radiation imaging inspection device) as a data binding identifier, and then associate the data acquired during this period of time with the device to be detected.
For the first mode of adopting the stop lever as a traffic control means, the construction cost of the detection channel is increased, and the waiting time for lifting and putting down the stop lever is needed by the equipment to be detected, so that the passing efficiency is low.
For the second mode, when the data acquisition device is abnormal (such as multiple, missed or delayed), or the following device to be detected enters the vehicle (that is, the distance between two devices to be detected is short), or the vehicle in the inspection channel temporarily stops, the associated data may be greatly interfered, so that the missing binding and the mis-binding are likely to occur; and once the correlation error occurs, domino effect can be caused, continuous errors are generated, and manual intervention is needed for recovery.

Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art.
The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention can be practiced without one or more of the specific details, or with other methods, components, and so forth. In other instances, well-known structures or operations are not shown or described in detail to avoid obscuring the invention.
Fig. 1 is a flowchart illustrating a processing method capable of automatically associating collected data according to an example embodiment. As shown in fig. 1, the method 10 includes:
step S110: and receiving collected data obtained by at least two data collecting devices sequentially collecting data of at least one device to be detected entering a detection channel. Wherein at least two data acquisition devices are arranged in the detection channel according to a predetermined sequence.
The at least two data acquisition devices include, for example: LPR equipment, CCR equipment, RM equipment, loadometer (or ground coil, etc.), radiographic inspection equipment, etc., and are disposed in that order within the detection channel, although the invention is not so limited.
Step S120: and respectively storing the acquired data of the at least two data acquisition devices in at least two storage queues corresponding to the at least two data acquisition devices according to a first-in first-out sequence.
Fig. 2 is a diagram illustrating correlation of collected data in a storage queue according to an example embodiment. Each queue in fig. 2 corresponds to the data acquisition device, for example, an LPR device corresponding to an LPR queue 2201, a CCR device corresponding to a CCR queue 2202, an RM device corresponding to an RM queue 2203, a weighbridge corresponding to a weight queue 2204, and a radiation imaging inspection device corresponding to a serial number queue 2205. It should be noted that the queues illustrated in fig. 2 are only for illustration and are not limiting to the present invention.
After the equipment A to be detected enters the detection channel, the data acquisition equipment sequentially acquires data of the equipment A to be detected and sequentially stores the acquired data in the corresponding storage queues. And then, the devices B and C to be detected enter in sequence, pass through the data acquisition devices respectively in sequence to obtain respective acquired data, and are stored in corresponding storage queues respectively.
In some embodiments, the storage of the collected data is performed after receiving a storage start instruction. The storage start instruction is, for example, data acquired by the first-ranked data acquisition device. Taking the example that the LPR devices are arranged in the first place, when the LPR devices acquire a new license plate, data storage is started, the data acquired by the LPR devices are stored in the LPR queue 2201, and subsequently received acquired data are stored in corresponding storage queues in sequence.
In addition, the data acquisition equipment arranged at the first can also be other equipment capable of identifying relevant information of the equipment to be detected, such as container number identification equipment, and a system special for some trucks can use the container number as the relevant information of the equipment to be detected; as well as or instead of Radio Frequency Identification (RFID) devices, some regional systems have vehicles equipped with Radio Frequency Identification (RFID) modules that identify the vehicles, and thus the identified RFIDs may also be used as information related to the devices to be detected, where the RFIDs include, for example, vehicle information, vehicle type information, cargo information, container number information, and the like. It should be noted that the above description of the device for identifying the related information of the device to be detected is only an example, and the invention is not limited thereto.
Step S130: and associating the acquired data stored in the at least two storage queues on the basis of each device to be detected.
With continued reference to fig. 2, as shown in fig. 2(d), after the acquired data of the device a to be detected is stored, the data arranged at the head is taken out from each queue, and then is associated as an acquired data packet of the device a to be detected.
In some embodiments, when the association start instruction is received, it is considered that the acquired data of the device a to be detected is stored completely. The association initiation indication includes, for example: the data acquisition completion indication sent by the last data acquisition device (e.g., the radiation imaging inspection device described above) is, for example, at least one of a scan completion indication or a scan image with completed processing, an indication that data arrives (i.e., data is stored) in the last storage queue (e.g., the serial number queue 2205 described above), an indication that the device a to be inspected leaves the inspection channel sent by a sensor disposed in the inspection channel, and an indication that the next device to be inspected enters the inspection channel.
The following takes data missing as an example to briefly describe the automatic data recovery mechanism of the processing method capable of automatically associating the collected data provided by the present invention. Fig. 4 is a schematic diagram of an automatic data recovery mechanism for automatically associating a processing method of collected data when data is missed according to an example embodiment. As shown in fig. 4, it is assumed that, as shown in fig. 4(a), data collected by the RM device of the device a to be detected is missed, while the device B to be detected only enters afterwards, and RM data of the device B to be detected enters the head of the RM queue. In correlating the data of the device a to be detected, as shown in fig. 4(B), the RM data of the device B to be detected is correlated into the data of the device a to be detected. However, as shown in fig. 4(C), before the association of the device B to be detected is performed, the RM data of the device C to be detected is not received, and after the data (lacking the RM data) of the device B to be detected is associated, the association of the data of the device C to be detected is not affected, so that the automatic recovery of the data is realized.
In addition, the invention also sets a timer for each stored collected data, thereby further enabling the processing method capable of automatically correlating the collected data to be capable of self-recovering under the conditions of delayed sending, multiple sending and the like of the data collecting equipment, and avoiding causing continuous correlation errors.
In some embodiments, each acquisition data is started with its respective timer when it is stored in its respective storage queue. When an acquired data is taken out from the queue stored by the acquired data and is associated with a device to be detected, the corresponding timer is stopped; and when a timer for collecting data times out, the collected data is discarded from the queue stored by the collected data. In addition, when the timer for collecting data is overtime, an alarm instruction can be sent to give an alarm, and the alarm instruction can carry data detection equipment corresponding to the collected data so as to warn that the equipment has problems.
The duration of the timer is set by referring to the length of the detection channel, the passing speed of the equipment to be detected and other factors. For example, the time length is configured according to the shortest time length which can ensure that the device to be detected is scanned, and is therefore related to the length of the detection channel and the passing speed of the device to be detected. If the time length is set to be too short, the data of the equipment to be detected is not acquired, and the acquired data is invalid; however, if the data design is too long, the timing of clearing invalid data will be affected, which is not favorable for the automatic recovery mechanism of data association.
The following briefly describes the automatic data recovery mechanism of the processing method capable of automatically associating the collected data, which is provided by the present invention, with two situations, namely, delayed sending and frequent sending, of the data collection device. Fig. 5 is a schematic diagram of an automatic data recovery mechanism of a processing method capable of automatically associating collected data when data is delayed according to an example embodiment. Fig. 6 is a schematic diagram illustrating an automatic data recovery mechanism for automatically associating a processing method of collected data when data is frequently generated according to an example embodiment.
As shown in fig. 5, the RM data of the device to be detected a is delayed from being sent, and since other data of the device to be detected a has been associated and taken out from each storage queue, the RM data of the device to be detected a is associated with the following data of the device to be detected B. And as for the RM data of the equipment B to be detected, as long as the subsequent equipment C to be detected does not perform data association before the RM data of the equipment B to be detected is discarded due to overtime of the timer, the RM data of the equipment B to be detected is discarded, so that the data association of the subsequent equipment to be detected is not influenced, and the automatic recovery of the data is realized.
As further shown in fig. 6, it is assumed that the RM device of the device a to be tested transmits RM data about the device a to be tested twice. Similarly, as for the RM data of the device a to be detected which is sent more, as long as the subsequent device B to be detected does not perform data association before the RM data of the device a to be detected which is sent more is discarded due to the timeout of the timer, the RM data which is sent more is discarded, so that the data association of the subsequent device to be detected is not affected, and the automatic recovery of the data is realized.
In addition, the processing method of the present invention may also implement automatic data recovery under other conditions (for example, the device to be detected exits the detection channel after triggering data acquisition, interferes with noise data, etc.), which is not illustrated herein.
The processing method capable of automatically associating the collected data provides a data association mechanism with timeliness, data acquired by each data acquisition device is respectively stored in a single storage queue, data association under the condition that a plurality of devices to be detected exist in a detection channel at the same time can be met, and after association errors caused by the condition that the data acquisition devices are missed and the like occur, self recovery can be carried out within a limited time, so that continuous association errors are avoided.
Fig. 3 is a block diagram of a processing device capable of automatically associating collected data according to an example embodiment. As shown in fig. 3, the system 20 includes: a data receiving module 210, at least two storage queues 220 and a data processing module 230.
The data receiving module 210 is configured to receive collected data obtained by sequentially collecting data of at least one device to be detected (not shown) entering a detection channel (not shown) by at least two data collecting devices (not shown), where the data collecting devices are arranged in the detection channel according to a predetermined sequence.
The at least two data acquisition devices include, for example: LPR equipment, CCR equipment, RM equipment, wagon balance, radiation imaging inspection equipment and the like are arranged in the detection channel in the sequence, but the invention is not limited to the method.
The storage queues 220 correspond to the data acquisition devices respectively, and are used for storing the acquired data of the data acquisition devices corresponding to the storage queues according to a first-in first-out sequence.
Still taking the storage queue shown in fig. 2 as an example, after the device a to be detected enters the detection channel, the data acquisition device sequentially acquires data of the device a to be detected, and sequentially stores the acquired data in the respective corresponding storage queues 220. Thereafter, the devices B and C to be detected enter in sequence, respectively pass through the data acquisition devices in sequence, so as to obtain respective acquired data, and are respectively stored in the corresponding storage queues 220.
In some embodiments, after receiving the storage start instruction, the data receiving module 210 stores the acquired data into corresponding storage queues respectively. The storage start instruction is, for example, data acquired by the first-ranked data acquisition device. Taking the example that the LPR devices are arranged in the first place, when the LPR devices acquire a new license plate, data storage is started, the data acquired by the LPR devices are stored in the LPR queue 2201, and subsequently received acquired data are stored in the corresponding storage queue 220 in sequence.
In addition, the data acquisition equipment arranged at the first can also be other equipment capable of identifying relevant information of the equipment to be detected, such as container number identification equipment, and a system special for some trucks can use the container number as the relevant information of the equipment to be detected; as well as or instead of Radio Frequency Identification (RFID) devices, some regional systems have vehicles equipped with Radio Frequency Identification (RFID) modules that identify the vehicles, and thus the identified RFIDs may also be used as information related to the devices to be detected, where the RFIDs include, for example, vehicle information, vehicle type information, cargo information, container number information, and the like. It should be noted that the above description of the device for identifying the related information of the device to be detected is only an example, and the invention is not limited thereto.
And the data processing module 230 is configured to associate the collected data stored in the storage queue 220 based on each device to be detected.
With continued reference to fig. 2, as shown in fig. 2(d), after the collected data of the device a to be detected is stored, the data processing module 230 takes out the data arranged at the head from the storage queue 220, and then associates the data with a collected data packet of the device a to be detected.
In some embodiments, when the association start instruction is received, it is considered that the acquired data of the device a to be detected is stored completely. The association initiation indication includes, for example: the data acquisition completion indication sent by the last data acquisition device (e.g., the radiation imaging inspection device described above) is, for example, at least one of a scan completion indication or a scan image with completed processing, an indication that data arrives (i.e., data is stored) in the last storage queue 220 (e.g., the serial number queue 2205 described above), an indication that the device a to be inspected leaves the inspection channel sent by a sensor (not shown) disposed in the inspection channel, and an indication that the next device to be inspected enters the inspection channel.
Fig. 4 is still used as an example to briefly describe how the processing apparatus capable of automatically associating collected data according to the present invention implements an automatic recovery mechanism of data association when data is missed. As shown in fig. 4, it is assumed that data collected by the RM device of the device a to be detected is missed as shown in fig. 4(a), and the device B to be detected enters only subsequently, so that RM data of the device B to be detected enters the head of the RM queue as shown in fig. 4 (B). In correlating the data of the device a to be detected, as shown in fig. 4(B), the RM data of the device B to be detected is correlated into the data of the device a to be detected. However, as shown in fig. 4(C), before the association of the device B to be detected is performed, the RM data of the device C to be detected is not received, and after the data (lacking the RM data) of the device B to be detected is associated, the association of the data of the device C to be detected is not affected, so that the automatic recovery of the data is realized.
In addition, the invention also sets a timer for each stored collected data, thereby further enabling the processing device capable of automatically correlating the collected data to be self-recovered under the conditions of delayed and frequent occurrence of the data collecting equipment, and the like, so as to avoid causing continuous correlation errors.
In some embodiments, each acquisition data is started with its respective timer when it is stored in its respective storage queue 220. When an acquired data is taken out of the storage queue 220 where it is stored, and is associated with a device to be tested, its corresponding timer is stopped; when a timer for collecting data expires, the collected data is discarded from the storage queue 220 where it is stored. In addition, when the timer for collecting data is overtime, an alarm instruction can be sent to give an alarm, and the alarm instruction can carry data detection equipment corresponding to the collected data so as to warn that the equipment has problems.
The duration of the timer is set by referring to the length of the detection channel, the passing speed of the equipment to be detected and other factors. For example, the time length is configured according to the shortest time length which can ensure that the device to be detected is scanned, and is therefore related to the length of the detection channel and the passing speed of the device to be detected. If the time length is set to be too short, the data of the equipment to be detected is not acquired, and the acquired data is invalid; however, if the data design is too long, the timing of clearing invalid data will be affected, which is not favorable for the automatic recovery mechanism of data association.
The following will briefly explain the automatic data recovery mechanism of the processing device capable of automatically associating and collecting data provided by the present invention under two situations, namely, a late time and a frequent time, by taking fig. 5 and fig. 6 as an example.
As shown in fig. 5, the RM data of the device to be detected a is delayed from being sent, and since other data of the device to be detected a has been associated and taken out from each storage queue, the RM data of the device to be detected a is associated with the following data of the device to be detected B. And as for the RM data of the equipment B to be detected, as long as the subsequent equipment C to be detected does not perform data association before the RM data of the equipment B to be detected is discarded due to overtime of the timer, the RM data of the equipment B to be detected is discarded, so that the data association of the subsequent equipment to be detected is not influenced, and the automatic recovery of the data is realized.
As further shown in fig. 6, it is assumed that the RM device of the device a to be tested transmits RM data about the device a to be tested twice. Similarly, as for the RM data of the device a to be detected which is sent more, as long as the subsequent device B to be detected does not perform data association before the RM data of the device a to be detected which is sent more is discarded due to the timeout of the timer, the RM data which is sent more is discarded, so that the data association of the subsequent device to be detected is not affected, and the automatic recovery of the data is realized.
