Detailed Description
The present invention is further illustrated by the following examples, which are illustrative of the present invention and are not to be construed as being limited thereto.
Radio Frequency Identification (RFID) is an abbreviation of Radio Frequency Identification, and its principle is that non-contact data communication is performed between a reader and a tag to achieve the purpose of identifying a target. The ultrahigh frequency radio frequency identification technology uses a high frequency band within a frequency range of 860-960MHz, has the advantages of long identification distance, capability of reading a plurality of tags at one time, strong penetrability and the like, and simultaneously, the passive electronic tag has low cost, small volume and light weight. And associating corresponding personnel information through the identification tag, and performing real-time identification and data analysis. Due to the fact that the exhibition people flow is large, the personnel identification data can feed back a large amount of content, and large data mining and analysis in different aspects can be conducted.
The invention discloses an exhibition personnel positioning method based on an ultrahigh radio frequency identification technology, which is characterized by comprising the following steps of:
the method comprises the following steps: as shown in fig. 1, rfid tag readers are evenly distributed in the exhibition room; a radio frequency identification tag reader is placed at each booth and the remaining radio frequency identification tag readers are placed at the corners of the remaining booths that are not covered.
Arranging the radio frequency identification tag readers on site in a gridding mode according to the conventional exhibition site size and taking 3m by 3m as a unit; each rfid tag reader is calibrated when it leaves the factory, and the range of linear detection is limited according to the signal strength (rssi) value, and other usage modes are implemented by adjusting the value of monitoring the signal strength. Therefore, the default setting is that the measuring radius range is 1.72 meters, and the judgment is not in the marked range if the distance is far away from the measuring radius range, so that the logic of area judgment can be reduced, and the subsequent improvement and adjustment can be carried out according to the actual situation. As shown in fig. 2, in this embodiment, the position where the device is installed is defined as 2.5 meters, and the height where the tag is located on the human body is defined as 1 meter to 1.5 meters.
Step two: radio frequency identification tags are arranged in the exhibition visit certificate and the employee certificate, and all the persons who enter the exhibition issue the visit certificate or the employee certificate provided with the radio frequency identification tags;
each exhibition person carries a visit certificate with a radio frequency identification tag to enter an exhibition range, radio frequency reading equipment is arranged at each exhibition position and a public channel, the range identified by each piece of equipment is set by calibration, and mutually overlapped areas rarely occur, as shown in fig. 1.
Step three: making an exhibition indoor map in the server, and dividing the working range of each radio frequency identification tag reader corresponding to the indoor map into different area blocks according to the distribution condition of the radio frequency identification tag readers in the step one;
the process of making the indoor map of the exhibition is as follows: the positioning system adopts standard grid arrangement, each grid is 3m by 3m, and the total grid range is intercepted according to the actual floor area of each exhibition; and marking the serial numbers of the exhibitions in the corresponding grids according to the layout of each exhibitor.
Step four: the radio frequency identification tag reader reads the radio frequency identification tag of the entrance personnel in the area and sends data to the server; in the exhibition area where the entrants are located, the frequency identification tag reader identifies signals corresponding to tags, sends tag codes in a detection range to the server through the network, and the tag codes are sorted and written into a table of the database by server software.
Step five: the server receives data from all rfid tag readers and displays the distribution of people within each block of the area on an indoor map. Readers are placed in the exhibition hall and each exhibition position, tags in the range are read, the tags are uploaded to a database, the database is used for matching and is associated with users, and data processing is carried out by a background, wherein the data processing comprises marking of personnel position information, counting of personnel stay time, recording of personnel moving routes, regional personnel concentration conditions and the like.
The database matching process is that the database carries out data association by using ID numbers, the database 1 stores personal information of personnel and ID numbers of an exhibition, the database 2 stores ID numbers of the exhibition and ID numbers of radio frequency identification tags, the database 3 stores ID numbers of radio frequency identification tag readers and serial numbers of exhibition positions, when the radio frequency identification tag readers acquire the radio frequency identification tag information and push the information data to the server, the information data comprises the radio frequency identification tag ID information and acquired time information, the server associates all data in the database according to the radio frequency identification tag reader ID and the radio frequency identification tag ID, and arranges the data information of the same personnel according to the time sequence.
Such as:
10:10:00 Access booth AB aisle (aisle radio frequency identification tag reader acquisition tag)
10:10:20 into exhibition booth A (radio frequency identification tag reader of A gathers the tag)
10:13:00 access booth AB aisle
10:13:30 entrance booth CD aisle
10:13:50 entry into booth D
10:16:20 into the booth CD aisle.
The method for representing the dense situation of the regional personnel comprises the following steps: the degree of density is expressed in a gradient manner by the total number of tags monitored by each collector, such as:
mobile phone end software used by a visitor searches the latest position code of the visitor tag ID by accessing a database, and displays a specific exhibition position or a specific passage position on a map of the mobile phone end;
the mobile phone end software used by the exhibitor also screens the data in the exhibition position by accessing the database, respectively counts the number of all visitor tags detected by the exhibition position receiver in a certain time period and the time length of each detected tag, and displays the tags in the corresponding information column of the mobile phone end.
Similarly, exhibition managers can also generally know the current number of people in each exhibition booth and aisle through mobile phones or computers, so that the crowdedness degree of people flow is judged.
Exhibition personnel have ultrahigh frequency radio frequency identification's label and get into indoor exhibition scope, through arranging the reading equipment in each position in the exhibition room, the authority and the information of discernment personnel, discernment exhibition personnel's position and upload to the server. The specific software program can help the visitor to obtain the relevant consultation by learning the position of the visitor; the exhibitor can obtain the information and analysis data of the exhibitor; exhibition managers can check the dense condition of people flow and count various personnel information.
The above description of the present invention is intended to be illustrative. Various modifications, additions and substitutions for the specific embodiments described may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
