Problems solved by technology
[0002] In general high-tech industries or defense industries, the protection of research and development secrets is very important, and such industries generally have strict access control for visitors, but the existing control of visitors is generally only registered at the entrance The method of distributing access control cards allows visitors to enter the company, but the behavior and area of the visitors after entering the company cannot be controlled. Therefore, this control method still cannot prevent people who want to steal or destroy important objects of the company.
[0003] In the existing regional positioning system, since the trigger device is only set at the key point of the area entrance and exit, and the positioning device is set somewhere in the area, the wireless signal transmission between the positioning device and the user positioning unit is used to determine whether the user is wearing the device. However, due to the arrangement of various items and the design of buildings in the area, there will be many dead spots that cannot be transmitted during wireless signal transmission, so that the regional positioning system cannot grasp the area. user's location
Since this kind of situation often exists in the existing regionalized positioning system, if you want to use such a regionalized positioning system to really grasp the whereabouts of the visitors, because of the aforementioned reasons, it often leads to misjudgment or even failure to grasp the area where the visitors are located. whereabouts of visitors

Embodiment Construction
[0013] In order to make the above-mentioned and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments of the present invention will be specifically cited below, together with the accompanying drawings, as follows:
[0014] figure 1 It is a diagram of a preferred embodiment of the regional positioning system of the present invention. Please refer to figure 1 , a regionalized positioning system 1 of the present invention, comprising: several trigger units 21-2n, which are respectively arranged at the entrances of several areas 31-3n and emit a trigger signal, and these trigger units 21-2n can be respectively adjusted according to the situation Use infrared rays, ultrasonic waves, or have a first transceiver antenna (not shown) to sequentially transmit a trigger signal (for example, a trigger signal with a frequency of 40kHz, but not limited thereto) through the first transceiver antenna and transmit a trigger signal throu...

The invention discloses a regional positioning system. When passing through one of a plurality of trigger units, a user positioning unit receives a triggering signal and is triggered to transmit a user positioning signal to the trigger unit, a positioning unit and a calibration unit; and a first received signal strength indication (RSSI) value, a second RSSI value and a third RSSI value are sequentially transmitted back to a host computer to determine a region in which the user positioning unit is located according to the sizes of the first RSSI value, the second RSSI value and the third RSSI value. Thus, the system improves the accuracy of region positioning, and can avoid loss of positioning of the user positioning units even if the signal transmission is blocked by objects.
Description
technical field [0001] The invention relates to a positioning system, in particular to a regionalized positioning system which makes regionalized positioning more accurate through several calibration units. Background technique [0002] In general high-tech industries or defense industries, the protection of research and development secrets is very important, and such industries generally have strict access control for visitors, but the existing control of visitors is generally only registered at the entrance The way of distributing access control cards allows visitors to enter the company, but the behavior and areas of the visitors after entering the company cannot be controlled. Therefore, this control method still cannot prevent people who want to steal or destroy important objects of the company. [0003] In the existing regional positioning system, since the trigger device is only set at the key point of the area entrance and exit, and the positioning device is set some...
