After step S130, the MCU 120 controls the RF communication module 130 to transmit the vehicle presence / absence determination information to the gateway 200 so that presence / absence of vehicle parking is transmitted to the parking management server 400 by the gateway 200 (Step S140) so that the number of parking spaces currently vacant is displayed through the parking status notification device 500 of the parking line so that the vacant parking space can be identified through the data collected by the parking management server 400. [

After step S140, the power management module 140 in the car stopper geomagnetic sensor 100 manages the power of the magnetic field sensing module 110 (S150) The standby power is cut off in a sleeping mode until the abnormal operation of the module 110 is detected.

The power management module 140 switches from a sleeping mode to a waking-up mode when a predetermined operational geomagnetism change is detected by the car stopper geomagnetic sensor 100, 120 and the RF communication module 130 by repeating the above-described steps S110 to S150.

Referring to FIG. 6, the magnetic field sensing module 110 of two or more car stopper geomagnetic sensor 100s adjacent to car stoppers 1a, 1b senses the changed geomagnetic value (S210).

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.

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.
