In the following description, A plurality of movable beacons 110a1-110a3, 110b1-110b2, 110c1-110c3, and 110d1-110d2 that are movable, and a plurality of movable beacons 110a1-110a2, And a positioning system 130, and a control server 200.

These mobile beacons 110a1-110a3, 110b1-110b2, 110c1-110c3, 110d1-110d2 are movable and can cross each unit space (a zone to d zone) divided into small spaces, In order to minimize the thickness, as shown in FIG. 2C, a BLE wireless MCU chip, a memory, and the like must be mounted on a wafer (CSP : Chip Scale Package), it can be implemented in film PCB or flexible PCB with SMT (Surface Mounter Technology). The movable beacons 110a1-110a3, 110b1-110b2, 110c1-110c3, and 110d1-110d2 may be a card type (for example, an RFID card) having a height of 3 mm or less, It is preferable to use a sticky type (for example, an RFID tag or a barcode tag) that can be attached. In addition, in order to make the power source unit usable for at least six months without charging or exchanging the battery, It is preferable to use a thin-film lithium ion battery and a thin-film beacon for ultra low power consumption.

A plurality of beacon scanners 120a-120d are installed one-by-one in each unit space (a to d) divided into small spaces as illustrated in FIG. 1, and each of the beacon scanners 120a to 120d The memory unit 122, the Bluetooth unit 123, the Wi-Fi unit 124, the network connection unit 125, and the power supply unit 126, which are implemented as a microprocessor (CPU) . Each of the beacon scanners 120a to 120d scans surrounding beacon signals in each unit space in which the beacon scanner 120a is located and obtains moving beacon information in real time within a predetermined distance (preferably within a maximum radius of 100m) And transmits the beacon information and the signal strength information of the mobile beacon acquired in the vicinity to the own beacon signal and transmits it to the control server 200 through Wi-Fi (Wi-Fi) or wired Ethernet cable. In addition, each of the beacon scanners 120a-120d is configured to perform a pure beacon function, and transmits a beacon signal based on the Bluetooth 4.0 protocol supporting low-power Bluetooth to neighboring devices, (For example, up to 100) mobile beacons at the same time, and a network access point for control in an Ethernet environment through bidirectional communication and IP address assignment of Bluetooth V4.1 and V4.2 (Access Point). Particularly, in consideration of the mass productivity, each of the beacon scanners 120a-120d can be implemented by replacing and replacing all the DIP type components with the SMD type, and a dedicated RTC (Real Time Clock) Can be implemented in hardware, and the Bluetooth unit and the Wi-Fi unit can be used to use all four channels of the combo adapter board, and USB to Serial hardware can be implemented by using USB as a USB console.

In addition, each of the beacon scanners 120a-120d can check the battery remaining amount of the power source portion in real time, and automatically adjust the beacon scanning time to be inversely proportional to the battery remaining amount when the remaining amount of the battery is less than a preset reference value, And adjust the beacon scanning time according to the remaining amount.

The calibration and positioning algorithm 130 may be implemented using a source data correction algorithm that corrects RF deviations of the mobile beacons 110a1-110a3, 110b1-110b2, 110c1-110c3, 110d1-110d2, and beacon scanners 120a-120d, And a positioning algorithm 132 for calculating the relative position between the mobile beacon and the beacon scanner using the reception intensity information between the mobile beacon and the beacon scanner, The beacon scanner 120a-120d, and the analysis terminal 10 connected to the beacon scanner in the form of a program. The following description will be made with reference to a form mounted on a separate analysis terminal connected to a beacon scanner.

The source data correction algorithm 131 can be implemented by an algorithm that corrects the deviation of the RF reception sensitivity of the movable beacon and the beacon scanner existing in the same space to one reference value. In other words, due to the characteristics of the RF product, the mobile reception beacons and beacon scanners existing in the same space (cell area) have an RF reception sensitivity of about 10% in the same space and at the same position. Therefore, The correlation between the average value at the position and the value obtained through the conducted test at the time of mass production is analyzed and the validity is analyzed with the value obtained through the air test, It is possible to solve the deviation of the RF reception sensitivity of the existing movable beacon and the beacon scanner.

In addition, the source data correction algorithm 131 may be implemented by a method for solving directional variables according to an antenna pattern. In other words, all the antennas have characteristics that the sensitivity varies according to the direction. Therefore, in order to solve this problem, a sensor capable of detecting the directionality of the antenna is installed in the mobile beacon, It is possible to correct the error by correcting the RF reception sensitivity deviation of the mobile beacon and the beacon scanner according to the directionality of the antenna detected through the antenna.

Based on the signal strength information between the movable beacon and the beacon scanner in the same space obtained by the beacon scanners 120a to 120d in each unit space, the positioning algorithm 132 calculates the distance between the movable beacon and the beacon in each of the same spaces using triangulation. Calculate the relative position between the beacon scanners and derive the location and movement path of the mobile beacon. The calibration and positioning algorithm 130 corrects the RF deviation of the mobile beacon and the beacon scanner to one reference value (e.g., error rate of 3% or less) and transmits the beacon signal in the same space Based on the signal strength information between the information and the beacon scanner, a relative position between each movable beacon and the beacon scanner within the same space is derived with an error rate within a certain range (for example, maximum 5 m). That is, in the case of the source data correction algorithm 131, a moving average filter is used to find the optimal average value considering the change of the actual value and the delay time until recognition, and a moving beacon in the same space and an RF The error rate can be reduced by correcting the deviation with respect to the reception sensitivity. In the case of the source data correction algorithm 131, in order to obtain a correlation between the receiving intensity varying non-linearly and the distance, The coordinates and distances for the mobile beacon and the beacon scanner in the same space can be derived by applying the triangulation method in the case of the positioning algorithm 132. [

For reference, the control server 200 receives in real time the signal strengths of the mobile beacons in the same space as the information obtained from the beacon scanners 120a to 120d in each unit space in real time, and stores them in the database 220 . In addition, the control server 200 processes the information obtained through the calibration and positioning algorithm 130 so that the user can easily recognize the information, thereby configuring a display window, operating the integrated control system, registering, And present them through these asset management apps so that customers can easily identify the information they want.

If the remaining battery level is less than a predetermined reference value In order to reduce the battery consumption, the beacon scanning time interval is increased relative to the battery residual amount, and thus the beacon scanning time is automatically adjusted according to the remaining battery level.

Each of the beacon scanners 120a to 120d scans surrounding mobile beacons 110a1-110a3, 110b1-110b2, 110c1-110c3, and 110d1-110d2 existing in the same space as itself, If the number of the mobile beacons is larger than the reference value, the mobile beacon information is transmitted by filtering in the descending order of the signal strength, so that the mobile beacon can be selectively scanned and transmitted only for the mobile beacon which is more accurately and reliably recognized.

When each of the beacon scanners 120a-120d confirms the information of the mobile beacon recognized and transmits information of a mobile beacon amount larger than the reference value, the beacon signal transmission period of the own beacon is shortened and the beacon signal is transmitted It is possible to quickly transmit information of a larger amount of mobile beacons. At this time, the control server 200 adds indexes to beacon signals to be transmitted to the transmitted beacon signals, .

Meanwhile, as described above, each of the beacon scanners 120a-120d transmits the beacon information and the signal strength information, which are obtained in the vicinity of the beacon scanner 120a-120d, to the beacon scanner 120a-120d via the Wi- The control server 200 receives in real time the signal strengths of the mobile beacons in the same space as the information obtained from the beacon scanners 120a to 120d in each unit space in real time and transmits the same to the database 220.
