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.

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 correcting algorithm 131, the mobile beacon in the same space and the RF reception of the beacon scanner based on the average value considering the change of the actual value and the delay time up to the recognition by using the moving average filter In the case of the source data correction algorithm 131, in order to obtain a correlation between the reception intensity and the distance which change non-linearly, a Kalman filter (Kalman filter) In the case of the positioning algorithm 132, coordinates and distances for a mobile beacon and a beacon scanner in the same space can be derived by applying a triangulation method.

The control server 200 receives in real time the signal strengths of the mobile beacons in the same space as the information obtained in 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 calculates a relative position between the movable beacon and the beacon scanner in each unit space through the correction and positioning algorithm 130 installed in a separate analysis terminal connected thereto, And processes the information derived from the information obtained from the beacon scanners 120a-120d so that the user can easily perceive the information, thereby configuring a display window, operating the integrated control system, registering, modifying, And present them through these asset management apps so that customers can easily identify the information they want.

Operation and effect of the manager-centric and location-based enterprise integrated asset management system using the mobile beacon and beacon scanner configured as described above will be described below.

First, as illustrated in FIG. 2A, a BLE wireless MCU chip 111 (for example, a CC2540 chip) including a BLE-related circuit for RF processing and an 8051 CPU core and memory as a microprocessor for digital processing and a filter 112 110b1, 110b2, 110c1-110c3, and 110d1-110d2 including a plurality of mobile beacons 110a1-110a2, 110a1, 110b2, 110c1-110c3, 110d1-110d2, Each of which includes a main controller 121, a memory unit 122, a Bluetooth unit 123, a Wi-Fi unit 124, a network connection unit 125, and a power supply unit 126, -120d).

If at least one of the mobile beacons then enters a unit space in which at least one of the beacon scanners 120a-120d is located according to the movement of the human or physical property, the beacon signal based on the Bluetooth 4.0 protocol The at least one of the beacon scanners 120a-120d in the same space can scan the corresponding beacon signal.

For example, when the moving beacons 110a1-110a3 (at least one or two or more of movable beacons 110a1-110a3) come in the unit space of the area a, the beacon scanner 120a installed in the unit space of the area a moves in the same space At least one of the movable beacons 110b1-110b2 is included in the unit space of the b zone, and the mobile beacon information is acquired and collected in real time within the maximum operating radius, The beacon scanner 120b installed in the unit space of the b zone scans the beacon signal of the surrounding beacon transmitted in the same space (within a maximum radius of 100m) in which the beacon scanner 120b is located, Information of the mobile beacon in motion is acquired and collected in real time, and at least one of the mobile beacons 110c1-110c3 The beacon scanner 120c installed in the unit space of the zone c scans the beacon signal of the surrounding beacon transmitted in the same space (within a maximum radius of 100 m) in which the beacon scanner 120c is located, (At least one or more of the mobile beacons 110d1 to 110d2) are received in the unit space of the d zone, the beacon scanner (or the beacon scanner) installed in the unit space of the d zone 120d scan the neighboring beacon signals transmitted within the same space (within a maximum radius of 100m) in which they are located, and acquire and collect moving beacon information in real time within the maximum operating radius in real time.

In each of the beacon scanners 120a-120d installed in one unit within the unit space, the built-in microprocessor checks the battery status of the power source unit in real time to check the remaining battery level. 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. [ Calculates a relative position between the movable beacon and the beacon scanner in each unit space through the correction and positioning algorithm 130 installed in a separate analysis terminal connected thereto, and derives the position and movement path of the movable beacon , The information derived from the information obtained from each of the beacon scanners 120a to 120d is processed so that the user can easily recognize the information, By presenting it through the asset management app, it makes it easy for customers to check the information they want.

At this time, in the calibration and positioning algorithm 130 installed in the analysis terminal, the mobile beacons 110a1-110a3, 110b1-110b2, 110c1-110c3, 110d1-110d2 existing in the same space and the beacon scanner Calculates the relative position between the movable beacon and the beacon scanner using the positioning algorithm 132 and the reception intensity information between the movable beacon and the beacon scanner, The path can be derived.
