The car stopper geomagnetic sensor 100 is mounted on a parking management system using a car stopper with a geomagnetic sensor when the car stopper 1a and the car stopper 1b are adjacent to each other as shown in Fig. Respectively.

In this case, when the magnetic field sensing module 110 of the two or more car stopper geomagnetic sensor 100 completes sensing the changed geomagnetism value, each car stopper geomagnetic sensor 100 transmits the sensed geomagnetism value to the magnetic field sensing module And then transmits the geomagnetism values to the gateway 200 by controlling the RF communication module 130 individually.

The gateway 200 is a wireless access point (AP), which can be installed outdoors or indoors in a parking lot, and receives various geomagnetism values from a plurality of car stopper geomagnetic sensor 100 through a network 300 ).

In this case, the gateway 200 preferably transmits to the parking management server 400 an identification number of each car stopper geomagnetic sensor 100 providing the geomagnetism value in addition to a plurality of geomagnetism values.

The display device 210 may be generated integrally adjacent to the gateway 200 or detachably so that it can be identified in front of the parking area in which the car stopper 1 of the vehicle 2 is installed, However, it is possible to provide a voice output module.

The network 300 is a communication network that is a high speed period network of a large communication network capable of large capacity, long distance voice and data service, and may be a next generation wired and wireless network for providing Internet or high speed multimedia service. When the network 300 is a mobile communication network, it may be a synchronous mobile communication network or an asynchronous mobile communication network. As an embodiment of the asynchronous mobile communication network, a WCDMA (Wideband Code Division Multiple Access) communication network is exemplified. In this case, although not shown in the drawing, the mobile communication network 700 may include an RNC (Radio Network Controller). Meanwhile, although the WCDMA network is exemplified, it may be a next generation communication network such as a 3G LTE network or a 4G network, or an IP network based on other IP. The network 300 transmits signals and data between the gateway 200, the parking management server 400, the user smartphone 600, and other systems.

The parking management server 400 extracts location information matching the respective identification numbers of the two or more adjacent car stopper geomagnetic sensor 100 from the database 410 and then stores the location information and the geomagnetism The geomagnetism pattern information about the vehicle 2 is generated. The parking management server 400 includes two car stopper geomagnetic sensors (not shown) attached to two car stoppers 1a and 1b as shown in FIG. 4, When the geomagnetism value changed by the magnetic field sensing module 110 on the right car stopper 1a is sensed, the sensing range of the car stopper geomagnetic sensor 100 of the left car stopper 1a and the right car stopper 1b overlaps the forward geomagnetic value And the second geomagnetism pattern information 3b formed by the left front geomagnetic value based on the single sensing range of the car stopper geomagnetic sensor 100 of the left car stopper 1a, The third geomagnetism pattern information 3c formed by the left front geomagnetism value due to the single sensing range of the car stopper geomagnetic sensor 100 of the right car stopper 1b can be generated.

The parking management server 400 generates the first to third geomagnetism pattern information 3a, 3b, and 3c from the left to the right by referring to the generated geomagnetic pattern information, After generating a graph type geomagnetism pattern information in real time, parking guidance information is generated again in real time based on the generated geomagnetism pattern information. Here, based on the density, position, and shape of each of the first geomagnetism pattern information 3a, the second geomagnetism pattern information 3b, and the third geomagnetism pattern information 3b when generating the parking induction information by the parking management server 400 . That is, when the density of the geomagnetism pattern information of the first geomagnetism pattern information 3a is relatively denser than the second geomagnetism pattern information 3b and the third geomagnetism pattern information 3b, The direction change information can be generated as the parking guidance information.

The user smartphone 600 performs wireless pairing with at least one of two or more adjacent car stopper geomagnetic radios 100. That is, the user smartphone 600 is a mobile device having a computing function possessed by the driver of the vehicle 2, and the user smartphone 600 possessed by the driver in the vehicle 2 is a car stopper geomagnetic sensor The RF communication module 130 of the corresponding car stopper geomagnetic sensor 100 is connected to the car stopper 1 or the display device 210 by inputting the identification number displayed on the display device 210 or outside the car stopper 1 assigned with the same identification number as the car stopper The wireless connection can be performed by performing the login process of FIG.

After step S110, each car stopper geomagnetic sensor 100 receives the sensed geomagnetism value from the magnetic field sensing module 110, and then controls the RF communication module 130 to transmit the geomagnetism values to the gateway 200 (S220).

After step S220, the gateway 200 transmits the geomagnetism values of the step S220 to the parking management server 400 through the network 300 (S230). In step S230, the gateway 200 may transmit the identification numbers of the car stopper geomagnetic sensor 100 to the parking management server 400 in addition to the plurality of geomagnetism values.

After the step S230, the parking management server 400 extracts location information matching the respective identification numbers of two or more adjacent car stopper geomagnetic sensor 100 from the database 410, And generates geomagnetism pattern information about the vehicle 2 in a manner of expressing the geomagnetism value matched with the location information on each parking space (S240).

After step S240, the parking management server 400 generates parking guidance information in real time through the geomagnetism pattern information (S250). The parking management server 400 includes two car stopper geomagnetic sensors (not shown) attached to two car stoppers 1a and 1b as shown in FIG. 4, When the geomagnetism value changed by the magnetic field sensing module 110 on the right car stopper 1a is sensed, the sensing range of the car stopper geomagnetic sensor 100 of the left car stopper 1a and the right car stopper 1b overlaps the forward geomagnetic value And the second geomagnetism pattern information 3b formed by the left front geomagnetic value based on the single sensing range of the car stopper geomagnetic sensor 100 of the left car stopper 1a, The third geomagnetism pattern information 3c formed by the left front geomagnetic value based on the single sensing range of the car stopper geomagnetic sensor 100 of the right car stopper 1b is first generated.

After that, the parking management server 400 generates geomagnetism pattern information of one graph type in real time from the left to the right of the generated first to third geomagnetism pattern information 3a, 3b, 3c, Based on the geomagnetic pattern information, parking guidance information is generated again in real time. Here, based on the density, position, and shape of each of the first geomagnetism pattern information 3a, the second geomagnetism pattern information 3b, and the third geomagnetism pattern information 3b when generating the parking induction information by the parking management server 400 . That is, when the density of the geomagnetism pattern information of the first geomagnetism pattern information 3a is relatively denser than the second geomagnetism pattern information 3b and the third geomagnetism pattern information 3b, The direction change information can be generated as the parking guidance information.

After the step S250, the parking management server 400 analyzes whether at least one of the two or more adjacent car stopper geomagnetic sensors 100 is wirelessly paired with the user smartphone 600 (S260).

After step S260, the parking management server 40 determines whether wireless pairing is performed between one or more car stopper geomagnetic sensor 100 and the user smartphone 600 (S270). Here, the wireless pairing is a short-range wireless communication method including the IEEE802.15.4e TSCH, ZigBee, WIFI, BlueTooth, etc. as a communication protocol. The wireless pairing is performed within the wireless communication coverage of the user smartphone 600 or each car stopper geographical wireless sensor 100 (User smartphone 600 or car stopper geomagnetic sensor 100) or one of the units (user smartphone 600 or car stopper geomagnetic sensor 100) or between each other.

If it is determined in step S270 that wireless pairing has been performed, the parking management server 400 transmits the geomagnetism pattern information generated in step S240 and the parking induction information in step S250 to the network 300 To the user smartphone 600 (S280).

After step S280, the user smartphone 600 outputs geomagnetism pattern information on the touch screen, outputs parking induction information through the speaker (S290), and operates the vehicle 2 and the user smart phone 600 Allow the driver to easily park.

Meanwhile, after step S270, steps S300 and S310 are performed simultaneously with steps S280 and S290. That is, when the parking management server 400 transmits the parking induction information to the display device 210 formed adjacent to the gateway 200 through the network 300 (S300), the display device 210 displays the parking induction information through the voice output module By outputting the parking induction information (S310), parking is easily performed to the driver who operates the vehicle 2 and the user smartphone 600.

On the other hand, if it is determined in step S270 that the wireless pairing is not performed, the parking management server 400 skips the processes of steps S280 and S290 described above, S300) and step S310.
