Description

System and method for managing location information}

The present invention relates to a location information management system and method using radio frequency signals, and more particularly, to a location information management system and method for collecting the movement direction information of the position measuring device.

Recently, a location information service for acquiring and managing location information of a moving object is activated through an RFID (RF IDentification) technology using a radio frequency (RF) signal, which is one of short-range wireless communication technologies. have. The location information service using the RFID technology is widely applied in real life, such as an access control system, an anti-theft system, and an electronic payment system in a building.

Among them, the access management system is a location information management system that receives the identification information of the RFID tag and controls the operation of a companion device such as an access control device.

In detail, the access management system performs an opening / closing operation of the access control apparatus by recognizing an RF signal transmitted by the RFID tag when an accessor or an object with an RFID tag intends to enter or exit a certain area in the building. .

For example, in an access control system, when an accessor with an RFID tag enters a signal transmission range of a signal generator that generates a signal at a predetermined cycle, the RFID tag operates to send a response signal including accessor identification information to the outside. Then, the response signal is received by the RFID reader and transmitted to the access management server to provide a location information service for controlling the access control device.

In the conventional access management system, only the operation of the RFID tag receiving the signal of the signal generator is applied as a condition for controlling the access control device, thereby moving direction information of the person wearing the RFID tag, that is, entering or leaving the building. There was a disadvantage in that location information such as information cannot be determined.

Or it is set to 'operation' mode.

In this case, the operation control unit 213 may apply the currently received reporting period setting information or maintain the previous reporting period according to the reporting period setting condition corresponding to each direction information. You can change it to one or keep it.

For example, when the determined direction information is 'entry direction', the operation controller 213 applies the direction determination rule table to determine the reporting period setting condition as 'change' and set the power mode to 'operation'. Can be. In this case, since the reporting period setting condition corresponding to the 'entry direction' in the direction determination rule table is 'change', the operation control unit 213 may report reporting period setting information included in the currently received identification condition signal (ie, 'D1'). Use to change the reporting period.

In this case, when the specific area into which the location measuring device 200 enters is an area requiring accurate location recognition by shortening the reporting period of the location information, the currently received reporting period setting information is a reporting period after leaving the specific area. Shorter reporting period setting information.

As such, when the reporting period is set relatively short, the power consumption of the position measuring apparatus 200, that is, battery consumption increases. Accordingly, the operation controller 213 determines that the determined direction information is 'deviation direction', that is, the previous reception location identification information is first location identification information (ie, A) of the first signal generator 110 and the current reception is performed. If the location identification information is the second location identification information (ie, B) of the second signal generator 120, the reporting period may be set using the report period setting information (ie, 'D2') included in the currently received identification condition signal. Change it.

In addition, when the determined direction information is any one of 'stand-by direction' or 'operation direction', the operation controller 213 may set the power mode to 'stand-by mode' or 'operation mode'.

That is, when the first and second signal generators 110 and 120, which are identification conditions of different specific zones, respectively, are the power mode operation zone and the power mode standby zone, respectively, the operation control unit 213 may determine the previous reception position identification information. If the first position identification information (ie, C) of the first signal generating apparatus 120 and the current reception position identification information is the second position identification information (ie, D) of the second signal generating apparatus 110, generating The power supply mode is set to the standby mode by detecting a standby mode, which is a power mode corresponding to one direction information ('standby direction').

In addition, the operation control unit 213 may report reporting period setting information included in the identification information of the first signal generating device 110 that receives the reporting period for reporting the location information when the generated direction information is the 'operation direction' (ie , D3).

In this manner, the operation controller 213 may apply the direction determination rule table according to another embodiment of the present invention to set a reporting period and a power mode according to the direction information. In addition, it is natural that the direction determination rule table according to another embodiment of the present invention may include a direction determination condition, a report period setting condition, and a power mode setting condition according to various location identification information in addition to the conditions included in FIG. 8.
