In this embodiment, the apparatus may be integrated in the terminal shown in fig. 1. As shown in fig. 2, the data association method provided by the embodiment of the invention includes the following steps:

In this embodiment, when associating a record generated by a first device with a record generated by a second device, a device pair is first acquired, where the device pair includes: the first device and the second device may include a photographing device, for example, the first device is an electronic probe, the second device is an RFID device, and the photographing device may have a certain working range, that is, a scanning range supported by the photographing device, for example, 100 meters, 110 meters, 120 meters, etc., which is not limited by the embodiments of the present invention.
Taking a photographing device as an example, when a record generated by a first device and a record generated by a second device are associated, the time required for the record generated by the first device and the record generated by the second device are the same, then the distance between the first device and the second device is required to be smaller than a preset distance, only when the distance between the first device and a bracket of the second device is smaller than the preset distance, the first device and the second device can generate records for the same object (such as photographing the same object at the same time) at the same time, wherein the preset distance can be 50 meters, 60 meters and 70 meters, and the preset distance can be selected by referring to the working ranges of the first device and the second device.

S102, acquiring at least one record pair with a time interval smaller than a preset time interval according to the record generated by the first device and the record generated by the second device.
The number of records generated by the first device can be multiple, and the number of records generated by the second device can be multiple; the record generated by the device generally includes the time of generating the record, for example, the image acquired by the electronic probe includes the time of acquiring the image, so the record generated by the first device in this embodiment may be all records within the first preset time, and the record generated by the second device may also be all records within the first preset time; alternatively, the record generated by the first device may be all records from the initial execution of the operation by the first device, the record generated by the second device may also be all records from the initial execution of the operation by the second device, and the time period for selecting the record generated by the first device and the record generated by the second device may be determined according to actual needs, which is not limited in the embodiment of the present invention.

It should be noted that, in theory, in this embodiment, in one record pair, the record generated by the first device and the record generated by the second device should be simultaneous, but because the software and hardware results of each device are different, the time of the record generation will also deviate, so the preset time interval may be determined according to the specific device, which is not limited in this embodiment of the present invention.
Of course, the above is described by way of example only with respect to one device pair, and in one possible design, the number of device pairs is plural, and for each device pair, at least one record pair whose recording time interval is less than the preset time interval may be acquired in the above manner.
And S103, if the number of the corresponding record pairs of the same record content in the equipment pair is larger than a preset value, associating the record pairs in the equipment pair.
In this embodiment, since there may be a plurality of records corresponding to the same record content in the records generated by the apparatus, as in table 1, among the four records generated by the electronic probe, the record content of the electronic probe-1, the record content of the electronic probe-2, and the record content of the electronic probe-4 are all user 2.
Also taking tables 1 and 2 as an example, the number of record pairs corresponding to the user 1 collected by the electronic probe is 1 (the electronic probe-3 and the RFID device-3), and the number of record pairs corresponding to the user 2 is 3 (the electronic probe-1 and the RFID device-1, the electronic probe-2 and the RFID device-2, the electronic probe-3 and the RFID device-3, which indicate that the record of the electronic probe collecting user 2 and the record of the RFID device collecting user 3 collide 3 times.
For each device pair, if the number of the record pairs in the device pair is greater than a preset value, associating the record pairs in the device pair, and if the preset value is 2, determining that the user 1 and the user 4 are not the same person in the above exemplary device pair because the number of the record pairs corresponding to the user 1 is 1 (less than 2);
and if the number of record pairs corresponding to the user 2 is 3 (greater than 2), determining that the user 2 acquired by the electronic probe and the user 3 acquired by the RFID equipment are the same, associating the two records of the electronic probe-1 and the RFID equipment-1, associating the two records of the electronic probe-2 and the RFID equipment-2, and associating the electronic probe-4 and the RFID equipment-4, so that the personnel acquired by different equipment simultaneously can be mapped with each other, and a more comprehensive monitoring mechanism can be established.
The data association method provided in this embodiment obtains a device pair, where the device pair includes: the method comprises the steps of acquiring at least one record pair with a time interval smaller than a preset time interval according to records generated by the first equipment and records generated by the second equipment, wherein each record pair comprises a record generated when the first equipment executes operation and a record generated when the second equipment executes operation, and if the number of record pairs corresponding to the same record content in the equipment pair is larger than a preset value, associating the record pairs in the equipment pair.

Based on the embodiment of fig. 2 described above, the method further includes how the device pairs are composed. The following is a description of a specific embodiment. Fig. 3 is a flowchart of a data association method according to another embodiment of the present invention, and as shown in fig. 3, the data association method according to the embodiment of the present invention further includes the following steps:
s201, acquiring position information of any two devices according to a device information table of each device.
Each device corresponds to a device information table, the device information table includes the position information of the device, and the device information table can be obtained after the device is installed and fixed at a certain position. In the implementation of the scheme, cartesian product operation is performed according to the device information table of each device, and the position information of any two devices is obtained.
S202, acquiring the distance between two devices according to the position information of the two devices.
In this embodiment, the location information of the device includes longitude and latitude information of the device, and according to the longitude and latitude information of two devices, the distance between the two devices can be obtained, and the specific calculation method is similar to the existing calculation method for calculating the distance by adopting longitude and latitude, and will not be described herein.
S203, if the distance between the two devices is smaller than the preset distance, forming a device pair.
In this embodiment, if the distance between the two devices is smaller than the preset distance, the two devices are formed into a device pair, and only when the distance between the first device and the second device is smaller than the preset distance, the first device and the second device can generate records for the same object (such as shooting the same object at the same time) at the same time, so as to realize record pair association, wherein the preset distance can be 50 meters, 60 meters or 70 meters, the preset distance can be selected by referring to the working ranges of the first device and the second device, and the specific value of the preset distance is not limited in the embodiment of the present invention.
According to the data association method provided by the embodiment, the position information of any two devices is acquired according to the device information table of each device, the distance between the two devices is acquired according to the position information of the two devices, and if the distance between the two devices is smaller than the preset distance, a device pair is formed. In this embodiment, device screening is performed based on the existing location information first, and compared with the prior art, the record generated by the device does not need to include the same field, so that the record generated by the device is unlimited, and the distance parameter associated with the data can be configured in a self-defined manner, thereby improving user experience.
Based on the embodiments of fig. 2 and fig. 3, when the number of the device pairs is plural, the method further includes assigning a group number to each device pair, which will be described below by using a specific embodiment. Fig. 4 is a flowchart of a data association method according to another embodiment of the present invention, and as shown in fig. 4, the data association method according to the embodiment of the present invention further includes the following steps:
s301, acquiring a device pair.
The number of the device pairs is multiple, each device pair comprises a first device and a second device, and the distance between the first device and the second device is smaller than the preset distance. The execution of step 301 is similar to that of step 101 shown in fig. 2, and will not be described here.
S302, assigning the group number to each device pair, and acquiring the group number of each device pair.
S303, for each device pair, adding the group number of the device pair to the record generated by the first device, and adding the group number of the device pair to the record generated by the second device.
Specifically, since the number of the device pairs is multiple, after the device pairs are obtained, the group number of each device pair can be allocated to obtain the group number of each device pair, and the group number of the device pair is the unique identifier of the device pair.
For example, if the number of the device pairs is 3, the device pairs are respectively a first device pair, a second device pair, and a third device pair, and the group number of each device pair is allocated, the group number of the first device pair may be 1-2, the group number of the second device pair may be 2-3, and the group number of the third device pair may be 3-4.
Then, for each device pair, the record generated for the first device is added with the (join) device pair group number, and the record generated for the second device is added with the device pair group number, taking the first device pair as an example, the record generated for the first device includes "8 points, user 1", indicating that user 1 is shot at 8 points, after adding the device pair group number, "8 points, user 1, 1-2", the record generated for the second device includes "9 points, user 3, 1-2", after adding the device pair group number.
The group number of the device pair is increased for all records generated by the first device and the group number of the device pair is increased for all records generated by the second device for each device pair in the manner described above.
