In another embodiment, the visitor whereabouts management system 30 further includes a suspension hint module; when the visitor arrives at the place appointed by the interviewee, judging according to the appointment purpose of the visitor, judging whether the alarm prompting function is needed, if the appointment purpose is appointment interview, continuing to monitor and pause the alarm prompting, if the appointment purpose is freight transportation and engineering construction, continuing to monitor and finding that the track is suspicious, prompting the alarm in time, and realizing intelligent monitoring control.
In the track management system, a shorter and feasible visitor walking route map is planned according to reservation places and modern parks, factories and building drawings. The remote card readers are distributed along the areas of modern parks, factories and buildings according to the identification distance; the remote card reader can send out radio frequency signals with a certain frequency, when a visiting card enters the effective identification range of the remote card reader, induced current is generated, the radio frequency tag of the visiting card is activated, the radio frequency tag sends out self information, the remote card reader receives and processes the information sent by the radio frequency tag and then transmits the information to the entrance guard display, the information is compared with a visitor walking route map, and if abnormality of a visitor walking route is found, feedback is carried out in an alarm mode.
When one or more radio frequency tags are simultaneously positioned in a remote card reader or the readable range of a plurality of remote card readers, under the conditions of shared channels and identical frequencies, the plurality of tags simultaneously send signals into a reading channel of one card reader to generate channel contention, the signals mutually interfere to generate data collision, so that communication between the card reader and the tags is failed, and the collision is the collision of the tags at the moment; when one or more readers send requests simultaneously, the wrong data or the same wrong electronic tag is generated among the readers, and the readers collide.
In order to avoid collision of card readers and/or collision of labels in the visitor track management system 30, the application adopts an RFID anti-collision calculation method when tracking the visitor track, wherein the RFID anti-collision calculation method comprises an ALOHA calculation method and a binary tree calculation method, and concretely comprises the following steps:
s10, enabling a plurality of tags to enter an effective identification range of a card reader, sending out ID information of the tags, and if the card reader receives information sent by less than 5 tags in the same section, processing the information by adopting an ALOHA calculation method; if the card reader receives information sent by more than 5 tags in the same interval, adopting a binary tree calculation method to process the information;
s20, one or more tags enter the effective identification range of a plurality of card readers at the same time, and if the plurality of card readers receive information sent by the same tag in the same section, an ALOHA calculation method is adopted for processing; and if the plurality of card readers receive the information sent by the plurality of tags in the same interval, adopting a binary tree calculation method to process the information.
The ALOHA calculation method is a way of randomly accessing information in multiple paths, and the core design concept is a method of applying first-come first-serve labels. If the electronic tag enters the system and is detected by the reader, the ID number of the electronic tag is sent to the reader, if the electronic tag information is sent, the electronic tag or other ID numbers for sending the information are entered in the interval, the information repetition condition possibly occurs, the information of the sent electronic tag is totally collided or partially collided, whether the received information is collided or not is detected by the reader, if the received information is collided, the reader can directly decide the reading and the writing, the reader sends the electronic tag with a stop command, and then the information is randomly resent, and the process effectively reduces the probability of collision. The binary tree method is to divide the electronic tags in the conflict state into two subsets of 1 and 0, firstly inquire the subset 0, if no conflict occurs, the electronic tags can be correctly identified, if the conflict exists, the electronic tags are divided into the subsets of 01 and 00, and the like until the electronic tags in the subset 0 are all identified, and then inquire the subset 1 information according to the step of inquiring the subset 0.
The RFID anti-collision calculation method can effectively process the collision of the card reader and the collision of the tag through the selection of the ALOHA calculation method and the binary tree calculation method by classification, improves the capability of the card reader for identifying the tag, and further improves the identification of the visitor walking track of the visitor by the visitor track management system 30.
In another embodiment, the visitor track management system 30 is further provided with a tracking vector filtering module in tracking the visitor walking track, and calculates the visitor track by adopting a tracking vector algorithm, so that the existence of redundant data is avoided, and the system data size is reduced, and as shown in fig. 4, the calculation method of the tracking vector algorithm is as follows:
s10: acquiring a tracking vector;
s20: searching the history information corresponding to the ID according to the label data stored in the tracking vector; wherein, the history information is stored in the hash table;
s30: if the history information is not searched, a final vector is derived and stored in the hash table; if the history information exists, the next step S40 is performed;
s40: after searching the corresponding historical information of the tag ID, comparing the historical information with the received ID information, if the historical information is different from the received ID information, changing the tag point positions, editing the tracking vector and writing the tracking vector in a hash table; otherwise, if the label point position is not changed, the next step S50 is performed;
s50: comparing the time points of the historical information and the tracking vector, if the historical information and the tracking vector meet the requirementThe need for data elimination rules is determined to be met and the tracking vector is deleted, otherwise, the tag repeats through the interval detected by the antenna, transmits the tracking vector and compiles within the hash table. Wherein t1-t2 is the detailed time for the visitor to visit at the R1 point, < >>Minimum residence time for guests in R1 region.
S60: when the visitor is located at the edge of the interval corresponding to the two card readers for access (as shown in fig. 5), if the access requirement is satisfiedThe redundant tracking vector is deleted. Wherein t1-t2 is the detailed time for the visitor to visit at the R1 point, < >>Minimum residence time for guests in R1 region. T1 is a first card reader, and T2 is a second card reader.
The method adopts the collection interval duration of 1-10 times/10S to collect the point positions of the visitor at intervals, and sends the collected point positions of the visitor to a gate guard display to form a tracking route map of the visitor. In this embodiment, the collection interval duration is 1/S. Since the RFID device applied by the visitor whereabouts management system 30 has high reliability but time is not very accurate, by filtering the tracking vector, the saving of the whereabouts history data amount can be reduced.
The filtering tracking vector module calculates the visitor whereabouts according to the tracking vector and stores the historical data by applying the hash table, so that the data processing is more efficient, the database capacity can be reduced, and the visitor whereabouts can be prepared to be displayed more efficiently.
The visitor background management system 40 is a middleware for data interaction between the intelligent visitor management system and the MY SQL database, is convenient for conveniently and quickly interfacing with a monitoring system, a security system and other systems, and can ensure property safety of companies and personal safety of staff.
The operation method of data interaction comprises the following steps:
s10, operating DOM through the java script. DOM (document object model); the method is mainly used for operating on the content of the HTML and XML documents. The DOM depicts a hierarchical node tree, and functions of adding, deleting, modifying, searching and the like of document contents are realized by operating the nodes.
S20, BOM is operated through javascript. A Browser Object Model (BOM) is one of the components of JavaScript, which provides objects that interact independently with content and with a browser window, with which interaction with HTML can be achieved.
