Description

Service terminal that provides various services using low-power broadband communication network and can be connected to the black box installed in the vehicle and the method of connecting the black box

The present invention relates to a service terminal that can be connected to a black box pre-installed in a vehicle as a terminal for providing various services to a driver of a vehicle at low power using a low power broadband communication network, and a method for connecting the black box.

Low Power Wide Area Network (LPWAN) is a low power broadband communication protocol that has recently been adopted as a wireless network for the Internet of Things (IoT). A network solution for the Internet of Things (1) uses data at all times but must be operated with a battery, etc., so that it can be transmitted with low power, and (2) it is always used, but because the amount of data is small, it does not need to be super-fast. 3) High cost communication network is difficult to use due to low economic efficiency. LPWAN has recently attracted attention as a wireless network for the Internet of Things as a solution to this need. LPWAN is a large coverage network of the Internet of Things and includes commercially available technologies such as LoRa, Sigfox, Ingenu, LTE-M, and NB-IOT.

For example, LoRa has the advantage of low power communication and a fairly wide coverage of up to 20 km. Sigfox has a 10 km coverage in the city and up to 30 km away from the city centre. Machine-type Communications (LTE-MTC) (or LTE-M), Narrowband (NB) LTE-M, and NB IoT are recently announced standards for LTE technology based on 3rd Generation Partnership Project (3GPP) releases 12 and 13 Power saving mode (PSM) is applied.

Meanwhile, the black box installed in the vehicle not only records a front state of the vehicle as a video using a camera but also stores still images when an event occurs using various sensors installed in the vehicle. Meanwhile, the black box may include a user interface such as a display or an input unit to receive various control commands from the user.

An object of the present invention is to provide a service terminal that can be connected to a black box installed in the vehicle as a terminal for providing various services to the driver of the vehicle at low power using a low power broadband communication network.

Another object of the present invention is to provide a method of connecting a black box of a service terminal for connecting a service terminal to a black box having only a port for connecting a GPS receiver. Since a conventional black box includes only a port for connecting a GPS receiver to a terminal for connecting an external terminal, a service terminal provides a method of displaying LPWAN data through a black box while mediating between the black box and the GPS receiver.

In order to achieve the above object, the service terminal according to the present invention may be connected to a black box. In this case, the black box is already installed in the vehicle with a first port for connecting the GPS receiver. The service terminal may be connected to the black box to provide various low power broadband communication network (LPWAN) services. The LPWAN service may be any service that can be provided to the vehicle driver through the LPWAN. In this case, the service terminal does not have a user interface of its own, but uses a user interface (display, touch pad, etc.) of a black box already installed in the vehicle.

The service terminal of the present invention includes an LPWAN interface, MCU and a power supply. The LPWAN interface may be connected to a low power broadband network (LPWAN) to transmit and receive LPWAN service data for LPWAN service. MC-U has a 2-1 port for connecting the internal GPS receiver, a 2-2 port for connecting the LPWAN interface, and a 2-3 port for cable connection to the first port of the black box, One of the GPS data received through the 2-1 port and the LPWAN service data received through the 2-2 port may be provided to the black box. The power supply unit supplies the DC operating power of the service terminal.

According to an embodiment, the MCU may (a) mediate the GPS data received from the built-in GPS receiver through the port 2-1 to the port 2-3 through the port 2-2 through the LPWAN. When the service data is received, if there is display data to be displayed to the user in response to the received LPWAN service data, the mediation of the GPS data is interrupted and the display data is provided to the black box through the second-3 port. As a result, the display data may be displayed on the display unit of the black box.

According to another embodiment, the MC can be provided by the black box through the 2-3 port while (b) mediating the GPS data received through the 2-1 port to the 2-3 port. Upon receiving the data, it is determined whether the data is transmitted to the built-in GPS receiver or for the LPWAN service. If the data is for the LPWAN service, the transmission of the GPS data is stopped and corresponding to the data provided by the black box. The LPWAN service data may be delivered to the LPWAN interface through the second-2 port and provided to an external management server through the low power broadband network.

The display data may be extracted from the LPWAN service data, or may be pre-stored by the MC oil corresponding to the LPWAN service data.

The GPS receiver generates GPS data. The service terminal of the present invention may be interconnected via a cable and a GPS receiver, or may be provided with a built-in GPS receiver.

The present invention also extends to a method for connecting a black box of the service terminal. In the method of the present invention, the MC-U of the service terminal having the 2-1 port, the 2-2 port, and the 2-3 port is connected to the GPS receiver through the 2-1 port, Connecting to the LPWAN interface through a second port, and connecting to a first port of the black box through the 2-3 port; Periodically relaying, by the MC, GPS data received through the port 2-1 to the black box through the port 2-3; When there is LPWAN service data received through the second-2 port while performing the brokering step, MCU transmits the LPWAN service data to the black box through the second-3 port. Include.

Using the service terminal of the present invention, it is possible to simultaneously connect a configuration for processing a service through a low power broadband network (LPWAN) as well as a GPS receiver to a conventional black box that provides only one port for connecting the GPS receiver.

Accordingly, the service terminal (1) not only delivers the GPS data received using the built-in GPS receiver to the black box, but also (2) the LPWAN service does not include a user interface such as a display unit and an input unit for low power operation. The necessary data can be displayed on the display unit of the black box, and a user control command can be input through the input unit of the black box.

Since the terminal of the present invention utilizes LPWAN, the terminal is driven at low power, and thus the terminal can be operated for a long time even with a small power such as a battery. Since LPWAN itself has a very low communication cost, the terminal operation cost can be kept very low.

Above all, there is a feature in using a black box and a GPS receiver that are already installed in a vehicle in order to simplify the service terminal itself of the present invention.

4 is a block diagram of a terminal according to another embodiment of the present invention.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 and 2, the system 100 of the present invention includes a black box 110, a GPS receiver 20, and a service terminal 130 installed in a vehicle 10. The management server 170 is connected to the service terminal 130 through the low power broadband network (LPWAN) (150). Hereinafter, the LPWAN 150 will be described using a LoRa network as an example. However, the present invention is not limited thereto and may be applied to networks such as Sigfox, Ingenu, LTE-M, and NB-IOT.

The black box 110 installed in the vehicle 10 may have a built-in camera (not shown) to record a situation in front of the vehicle and store it as a video or still image, and connect the GPS receiver 20. A conventional black box having a first port 110a in accordance with a Universal Asynchronous Receiver / Transmitter (UART) protocol. The black box 110 may include a display unit 111 capable of displaying various information to the driver and playing and displaying a video, and an input unit 113 for receiving a driver's control command. Although the display unit 111 and the input unit 113 are preferably implemented integrally like a touch screen, the present invention is not limited thereto.

The black box 110 is connected to the service terminal 130 according to the UART protocol. The black box 110 includes a black box controller 115 and an LPWAN data processor 117 for the operation of the present invention. The black box controller 115 controls the existing black box operation and is not a characteristic configuration of the present invention.

The LPWAN data processing unit 117 displays the display data received from the service terminal 130 on the display unit 111 in the process of processing the LPWAN service data described below, and receives data input from the user through the input unit 113. To the service terminal 130.

The LPWAN 150 includes a plurality of LPWAN gateways 151 and LPWAN servers 153 to connect between the service terminal 130 and the management server 170. The LPWAN server 153 is connected to a plurality of LPWAN gateways 151. Hereinafter, the data included in the LPWAN data packet transmitted and received between the service terminal 130 and the LPWAN gateway 151 will be referred to as 'LPWAN service data'. For example, when the LPWAN 150 is a LoRa network, the LPWAN 150 may include a LoRa gateway 151 and a LoRa server 153 and transmit LoRa data packets for the LPWAN service.

The management server 170 operates various LPWAN services by the service terminal 130 of the present invention as a whole, and may register and manage a driver for its operation. Through driver registration, the management server 170 matches and stores the terminal identification number and the driver information with each other. Here, the driver information includes a login ID, a password, and the like, and if the LPWAN service of the service terminal 130 is provided to another mobile device (such as a mobile phone, etc.) of the driver's personal as described below, Information of the device (phone number, MAC address, etc.) may also be included.

Here, the LPWAN service may be any kind and type of service that may be performed by the interaction of the LPWAN service data between the service terminal 130 and the management server 170. For example, by using the various information obtained by the service terminal 130, for example, it may provide a service for preventing theft of the vehicle, may provide a service for preventing the drowsy driving of the vehicle driver, when the vehicle is parked / stopped A driver calling service for calling a vehicle driver may be provided. For example, the driver call service may receive a driver call command of a preset type from the caller for calling the vehicle driver by the service terminal 130, and provide the driver call command to the management server 170. The call result is provided from the management server 170 and displayed to the caller. However, the LPWAN service itself is not the core matter of the present invention, and thus will not be described in detail here.

The service terminal 130 is installed inside the vehicle 10, and includes a power supply unit 201, an LPWAN interface 203, and an MC controller (main controller unit) (MCU), and a power supply unit 201 and an LPWAN interface ( And a case 230 for accommodating 203 and the MC oil 210. Meanwhile, the service terminal 130 may include a necessary configuration (eg, a sensor) for the LPWAN service or may be connected to another external device.

In the present invention, the service terminal 130 is connected to the GPS receiver 20 and the black box 110. However, according to an embodiment, as shown in FIG. 4, the service terminal 400 may include a built-in GPS receiver 20. Since the present invention is characterized in that it simultaneously connects a configuration for processing a service through a low power broadband network (LPWAN) as well as a GPS receiver to a conventional black box 110 that provides only one port for connecting a GPS receiver. to be.

The power supply unit 201 provides a DC operation power source for the operation of the service terminal 130. The power supply unit 201 may use an internal battery. Since the service terminal 130 of the present invention is characterized by operating at low power by using LPWAN, it is possible to supply power for a considerably long time even using an internal battery. Alternatively, the power supply unit 201 may receive DC power from a vehicle battery (not shown) through a fuse box (not shown) of the vehicle 10 and supply DC to operating power.

The service terminal 130 may be configured to always operate, but may operate only when the driver has specially operated. In this case, the power supply unit 201 may further include a separate means (switch, button, etc.) for receiving the control command for starting and ending the operation from the driver to provide to the MC (210).

The LPWAN interface 203 has an antenna (not shown) and can communicate with the LPWAN gateway 151 in a wireless channel according to the LPWAN service protocol. The service terminal 130 is connected to the management server 170 through the LPWAN gateway 151. Therefore, the LPWAN interface 203 provides the information provided by the MC 210 to the management server 170, receives the information provided by the management server 170, and provides the information to the MC 210.

The MC 210 controls the overall operation of the service terminal 130 of the present invention and may collect various information for providing the LPWAN service together with the management server 170 or LPWAN service provided by the management server 170. Can process data However, as described above, the LPWAN service itself is not the core content of the present invention and thus will not be described in detail.

The essential operation of the MC (210) proposed in the present invention is to interconnect between the GPS receiver 20 and the LPWAN interface 203 and the black box 110. MCU 210 is typically implemented as a single chip in hardware, and includes a plurality of ports for interconnecting the GPS receiver 20, LPWAN interface 203 and the black box 110. The port includes a second-first port 210a allocated to a connection to the GPS receiver 20 and a second connection to the LPWAN interface 203 through an inter-integrated circuit (I2C) or serial peripheral interface (SPI) protocol. The second port 210b and the second port 210c connected to the first port 110a of the black box 110 through the UART protocol are included. The 2-1 port 210a, the 2-3 port 210c, and the first port 110a complying with the UART protocol include one set of Tx, Rx, VCC, and GND terminals, respectively. Among them, the second port 210c and the first port 110a interconnect four terminals Tx, Rx, VCC and GND using four cables.

In addition, since MCU 210 operates in a state where software for the control operation is installed, the LPWAN client unit 211 and the connection control unit 213 are shown in FIG.

As shown in FIG. 2, the black box 110 includes only the first port 110a according to the UART and needs to receive GPS data from the GPS receiver 20. Therefore, the service terminal 130 should basically bypass the data received from the GPS receiver 20 to the black box 110 as it is. If the LPWAN service data is received from the LPWAN 150 while mediating the GPS data, the MC 210 processes the LPWAN service data according to a preset protocol and algorithm. The black box 110 is connected to two devices through one UART port.

Some LPWAN service data may be processed by (1) MCU 210 itself, and (2) user confirmation or control may be required. The LPWAN service data of (1) that can be processed by the MCU 210 itself corresponds to the LPWAN client unit 211 according to a preset algorithm by itself. The problem is in case (2) that user must receive confirmation or control command. In this case, the user needs to inform the user of necessary information and receive a necessary control command from the user. In the present invention, the display unit 111 and the input unit 113 held by the black box 110 are used.

The LPWAN client unit 211 analyzes the LPWAN service data provided from the LPWAN interface 203 and processes the LPWAN service data according to a predetermined algorithm. If, as in the case (2), there is 'display data' to be displayed to the user in response to the LPWAN service data, the LPWAN client unit 211 transmits the 'display data' to the connection controller 213. The display data may be data extracted or separated from the LPWAN service data, or may be data pre-stored by the MC oil 210 in response to reception of specific LPWAN service data.

The connection controller 213 performs a process according to the UART protocol through the 2-3 port 210c. First, the connection controller 213 basically relays the GPS data received through the 2-1 port 210a to the 2-3 port 210c. When the display data is received from the LPWAN client unit 211 during the mediation of the GPS data, the connection control unit 213 converts the display data into a data packet according to the UART protocol and transmits the black box through the 2-3 port 210c. To 110).

Meanwhile, when the connection controller 213 receives the UART data packet from the black box 110 through the 2-3 port 210c, the connection controller 213 parses the UART data packet and performs the GPS receiver through the 2-1 port 210a. 20) or whether to forward to the LPWAN client unit 211. If forwarding to the LPWAN client unit 211, the connection controller 213 parses the UART data packet to extract the data, and then forwards to the LPWAN client unit 211.

Hereinafter, the operation of the MC oil 210 will be described in more detail with reference to FIG. 3.

When the service terminal 130 starts to operate, the connection controller 213 periodically relays the GPS data input to the 2-1 port 210a to the 2-3 port 210c. In other words, the connection controller 213 connects the GPS receiver 20 and the black box 110. Since the 2-1 port 210a and the 2-3 port 210c follow the same protocol, the 2-1 port 210a and the 2-3 port 210c may be connected by simple intermediation. The black box controller 115 of the black box 110 uses the GPS data periodically received through the first port 110a connected to the 2-3 port 210c for its own service.

Even if there is data provided by the black box 110 to the GPS receiver 20, the connection controller 213 connects the 2-1 port 210a and the 2-3 port 210c, and thus, the GPS receiver as it is. Mediated to (20).

While repeatedly performing step S301, the LPWAN interface 203 periodically or aperiodically receives the LPWAN data packet through the LPWAN 150, extracts LPWAN service data, and provides the LPWAN client unit 211 to the LPWAN client unit 211.

While repeating step S301, if the LPWAN service data is received from the LPWAN interface 203 through the step S303, the LPWAN client unit 211 analyzes the LPWAN service data and displays the content to the user in response to the corresponding LPWAN service data. Determine whether there is a need or need to receive user control commands.

In the determination of step S305, if the LPWAN client unit 211 determines that the corresponding LPWAN service data can process itself, the LPWAN 150 performs the reception process or other response through the LPWAN interface 203 according to a predetermined algorithm. To provide. Data transmitted to the LPWAN 150 is transferred to the management server 170 as needed to be used for the LPWAN service.

In step S305, if it is determined that the LPWAN client unit 211 has a matter to be displayed to the user or needs to receive a control command of the user in response to the LPWAN service data, the LPWAN client unit 211 extracts the display data from the corresponding LPWAN service data or The pre-stored display data corresponding to the LPWAN service data is extracted from the internal memory and provided to the connection controller 213.

The connection controller 213 makes the display data into a data packet according to the UART protocol, and the LPWAN data processor of the black box 110 through the second port 210c and the first port 110a of the black box 110 ( 117). During the transmission of the display data, the mediation of the GPS data input through the 2-1 port 210a is stopped. The connection control unit 213 resumes mediation of the GPS data upon completion of the transfer of the display data.

The LPWAN data processing unit 117 displays the display data to the user through the display unit 111.

In the above method, the method for connecting the black box 110 of the service terminal 130 of the present invention is performed.

After checking the data displayed on the display unit 111 or as required, if the user inputs a control command necessary for the LPWAN service through the input unit 113, the LPWAN data processing unit 117 sends the control command to the UART protocol. The data packet is converted into the corresponding data packet and provided to the MC oil 210 through the first port 110a and the second-3 port 210c.

When the connection control unit 213 of the MC 210 receives the UART data packet from the black box 110 through the 2-3 port 210c, the head of the UART data packet is parsed so that the corresponding UART data packet is an LPWAN client. It is determined whether to transfer to the unit 211 or the GPS receiver 20. Since the parsed data will be delivered to the LPWAN client unit 211, the connection controller 213 parses the UART data packet, extracts a user control command, and then transfers it to the LPWAN client unit 211. The LPWAN client unit 211 processes the user control command itself according to an algorithm set in the user control command, or provides the management server 170 with the user control command or the data preset for the user control command through the LPWAN 150. do.

1 and 2, the GPS receiver 20 is described as a separate device installed in the vehicle 10 to connect to the service terminal 130. In other words, the terminal 130 has been described as interconnecting the GPS receiver 20 and the black box 110 pre-installed in the vehicle 10.

However, the present invention is not limited thereto. Since the present invention has a feature of simultaneously connecting a configuration for processing a service through a low power broadband network (LPWAN) as well as a GPS receiver to a conventional black box 110 that provides only one port for connecting a GPS receiver, The service terminal of the present invention may also incorporate a GPS receiver, and FIG. 4 shows an example.

The service terminal 400 of FIG. 4 includes a power supply unit 201, an LPWAN interface 203, an MCU 210, and a built-in GPS receiver 20, which are included in one case 401. The service terminal 400 of FIG. 4 packs only one service terminal 130 and the GPS receiver 20 of FIG. 2 into one device.
