Signal engraving and some positioning algorithm, such as one of the ΤΟΑ algorithm and the TDOA algorithm, The visitor wearing the wristband tag 201 is positioned to obtain the visitor's actual location information, and then the location information is sent to the judging module 103 of the visitor management subsystem 1.

[0060] It should be noted that, in the embodiment of the present invention, the actual positioning position may be the actual two-dimensional coordinates of the visitor or the real three-dimensional coordinates of the visitor, depending on the same monitored visitor. How many base stations are used to transmit the ultra-wideband pulse signals respectively transmitted by the wristband tag 201 worn by the visitor. For example, if the engraving calculations of the respective super-wideband pulse signals transmitted by the three base stations are used, the positioning server 203 calculates the actual two-dimensional coordinates of the visitor, and if the four or more base stations transmit the respective receiving ultra-widebands. The engraving calculation of the pulse signal, the positioning server 203 calculates the real three-dimensional coordinates of the visitor, and a typical embodiment uses four or more base stations to receive the engraving of the ultra-wideband pulse signal transmitted by the pass card. To calculate the actual coordinates of the visitor.

The determining module 103 is configured to acquire, according to the location information of the visitor, the subscription registration information corresponding to the visitor from the database 105, and determine, according to the acquired subscription registration information and the location information, Whether the visitor appears in the reserved access area during the reserved visit time, when the visitor exceeds the reserved access area or the visitor appears in the reserved access area and the reserved access time Correspondingly, the alarm module 104 is controlled to automatically issue the alarm information of the abnormal behavior of the visitor.

[0062] In the embodiment of the present invention, the location information includes a location location, a certificate information, and a location of the visitor. After receiving the location information of the visitor, the determining module 103 firstly obtains the certificate information from the database according to the location information. Obtaining a reserved access area and a reserved access time corresponding to the visitor, and then determining whether the visitor is in the reservation according to the positioning and the positioning position and the obtained reserved access area and the reserved access time. The access area appears in the reserved access area, and when the visitor exceeds the reserved access area or the visitor appears in the reserved access area does not match the reserved access time, the control is performed. The alarm module 104 automatically sends the alarm information of the abnormal behavior of the visitor. The alarm module 104 herein may specifically include a display unit and a speaker. The display unit is used to display the actual positioning position of the visited guest, the actual positioning point, and the document. Detailed information such as information, reservation access area, and appointment visit time, the speaker is used to mention The special workplace managers have the visitor abnormal behavior, so that managers can take measures among the first visitors inch abnormal manage. [0063] As can be seen from the above, the system for managing the visitor of a special work site provided by the embodiment of the present invention can enable the manager of the special work place to grasp the position of the visitor and the abnormal position of the visitor. The management personnel will send out alarm information so that the management personnel of the special workplace and the corresponding measures can prevent the visitors from making things that endanger the property safety and personal safety of the workers in the special workplace; on the other hand, they can work in special workplaces. Visitors who have the wristband label 201 are issued with high-precision positioning, and the stability of the positioning can be enhanced to avoid the occurrence of false positions in the positioning position, and the management of the special workplace can be well assisted to manage the visitor.
