Description

Technical Field [0001] The present invention relates to a method of providing a vehicle security, a vehicle security system, and a service terminal for the system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle security system that notifies a driver when a vehicle is stolen or towed by using a service terminal that provides various services to a driver of the vehicle with low power using a low power broadband network.

Low Power Wide Area Network (LPWAN) is a low-power broadband communication protocol and recently adopted as a wireless network for the Internet of Things (IoT). The network platform for the Internet for the Internet always uses data, but it has to operate with a battery, so it needs to be able to transmit low power and use it at all times, but since the amount of data is small, it does not need to be super high speed. There are features that are impossible. LPWAN has recently received attention as a wireless network for the Internet of Things as a solution to this need. LPWAN is a very large coverage network of the Internet, and includes commercialized technologies such as LoRa, Sigfox, Ingenu, LTE-M, and NB-IOT.

LoRa, for example, has the advantage of having low power communication and a fairly wide coverage of up to 20 km. Sigfox has a coverage of 10 Km for cities and 30 Km for cities. LTE-M (Machine-type Communications) (or LTE-M), NB (Narrowband) LTE-M and NB IoT are recently announced standards for LTE technology based on 3rd Generation Partnership Project (3GPP) , Power saving mode (PSM: Power Saving Mode), and the like are applied.

On the other hand, a black box installed in a vehicle not only records a forward state of a vehicle using a camera but also stores still images when an event occurs using various sensors installed in the vehicle. On the other hand, the black box includes a user interface such as a display or an input unit, and receives various control commands from a user.

In addition, various devices for detecting theft of the vehicle are provided. Such aft detection device is connected to an on-board diagnostic (OBD) of the vehicle to acquire various information of the vehicle to determine whether or not the vehicle is stolen. Since onboard diagnostics have begun to be applied recently, not all vehicles can have this type of theft detection device, and the overall price is high.

On the other hand, although a black box and the like installed in a vehicle are implemented not to be connected to an on-board diagnostic device but to operate independently, a user interface such as a display unit or an input unit is provided. You can consider a security system.

The service data generation unit 213 provides the vehicle security service, which is the LoRa service of the present invention, together with the service terminal 130. The service data generation unit 213 generates vehicle status information and periodically or aperiodically transmits the generated vehicle status information to the service terminal 130. The vehicle status information includes the speed and / or position of the vehicle and the ACC status information. The LoRa service will be described again in the description of the management server 170 below.

The service data generation unit 213 first calculates the speed (and / or position) of the vehicle using the GPS data transmitted through the service terminal 130, The ACC signal is read from the box (not shown). The ACC signal is a signal that is turned ON only when the vehicle is key-on and the service data generator 213 generates ACC status information when the ACC signal is ON. The service data generation unit 213 periodically generates vehicle status information and provides the generated service status information to the service terminal 130. The service data generation unit 213 may generate the vehicle status information even when the service terminal 130 is requested.

Service terminal

The service terminal 130 is a terminal connected to the LPWAN 150 via a wireless channel. The service terminal 130 of FIG. 2 shows an example in which the LPWAN 150 is a LoRa network.

2, the service terminal 130 is installed inside the vehicle 10 and includes a second power supply unit 231, a LoRa interface unit 233, and a MCU (Main Controller Unit) 250 . Meanwhile, the service terminal 130 is connected to the GPS receiver 20 and the black box 110 according to the UART protocol.

The service terminal 130 transmits and receives data to and from the management server 170 and provides the vehicle security service of the present invention to the driver. The service terminal 130 is connected only to the LoRa gateway 151 by using the LoRa interface 233. The data transmitted to the LoRa gateway 151 is transmitted to the management server 130 via the LPWAN 150 and the Internet 30, (170). Data provided by the management server 170 is also finally transferred to the service terminal 130 via the Internet 30 and the LPWAN 150. [ Therefore, in the following description, the expression that the service terminal 130 transmits data to the management server 170 or the expression that the management server 170 transmits data to the service terminal 130 is not limited to the LPWAN 150 ") and the Internet (30).
