The present invention relates to a wake-up device and method, and more particularly, to a power supply device of a telematics device that can remotely control the power of a telematics device mounted on a vehicle using a personal terminal such as a mobile phone. And to a method.

In general, computer networks for sharing information in limited spaces such as homes or offices are configured through well-known local area networks (LANs) such as Ethernet and Token Ring. However, as communication and use of information through the network has increased, it has become necessary to share information in a wider area, freeing up from space constraints. Therefore, a wide area network (WAN) is used to connect small networks. have.

Internet networks that share information over a wide area use Internet Protocol (IP) addresses to distinguish each other's namespaces. Therefore, a built-in wake-up device on the network card allows the power supply to be restored to the personal computer's main board when a data packet is received requesting power-up from its IP address.

In general, the power-operating device cuts off the power supply or keeps it at the minimum level if there is no input for a certain period of time from the user, and prevents unnecessary power consumption, and restores the power supply when the input is generated by the user. Make the operation possible. Representative power supply devices include a power supply device embedded in a network card of a personal computer, and devices supporting a sleep mode of a personal mobile communication terminal such as a mobile phone and a PDA.

Personal mobile communication terminals such as laptops, PDAs, etc. due to the limitation of the battery supplying power, the problem of power consumption is becoming important. Therefore, sleep mode support and wake-up function are essential to reduce power consumption. The sleep mode added to a notebook or a PDA temporarily backs up programs residing in the memory of the terminal to a permanent storage device to minimize power consumption due to the operation of the memory.

Recently, technologies for remotely controlling home appliances or computers through a home network using a personal mobile communication terminal with a built-in communication module such as a mobile phone have been developed. In this case, the home appliance or computer under control must be supplied with power to maintain the standby state. In home networks, however, there are few power constraints, so the performance of power-on devices is not a big issue. In contrast, in the case of a vehicle, when the telematics device mounted on the vehicle is continuously operated while the vehicle is not running, the power of the vehicle may be completely consumed due to power consumption. Therefore, a situation where an inability to start can occur, so an efficient power management is required. In addition, when a traffic accident occurs and a situation where the power of the vehicle cannot be used, it is difficult to request a service to a telematics center through a telematics device.

It is configured to prevent unnecessary power consumption.

The present invention more efficiently operates the power of the telematics device 100 through a remote control, and informs the telematics center of the vehicle's state and location when an emergency situation or action is required so that a quick service can be provided.

The power supply device 110 of the telematics device according to the present invention is connected to the telematics device 100, the microcomputer 111 having a central processing unit (CPU) and a memory, a communication modem 112 connected to a wireless communication network, A position acquisition unit for acquiring position information and route information of the vehicle through a power monitoring and control unit 113 for monitoring and controlling the power supply unit 101 and the vehicle power supply 121 of the telematics device 100, and a GPS satellite; 114 and a power supply unit 123 for providing an operating power source. The communication modem 112 should be assigned an Internet Protocol (I.P) necessary for communication for communication via a wireless communication network or a telephone number from a mobile communication company. The power supply monitoring and control unit 113 is connected to a switching unit 120 configured of a relay or the like to connect the vehicle power source 121 with the power supply unit 101 of the telematics device 100.

The microcomputer 111, the communication modem 112, the power monitoring and control unit 113, and the switching unit 120 are operated by a power supplied from a power unit 123 composed of a rechargeable battery, and the power unit 123. ) May be charged by the auxiliary power source 124 or the vehicle power source 121. For example, when the auxiliary power source 124 is configured of a solar panel or the like, the power source unit 123 may be charged by the auxiliary power source 124 during the day, and may be charged by the vehicle power source 121 at night. You can do that. An isolation transformer 122 is connected between the vehicle power source 121 and the power source unit 123 so that the power source unit 123 independently supplies power when the vehicle power source 121 is not available. The power monitoring and control unit 113 periodically detects the state of the power supply unit 123 and outputs a control signal to the isolation transformer 122 when charging is required, thereby controlling the vehicle power supply 121 and the power supply unit 123. Connect it.

The microcomputer 111 includes a central processing unit (CPU) operated according to an operation program and a memory for storing registration information input from a user.

The communication modem 112 maintains a call waiting state (step 200). When a call is received from the user's terminal through the wireless communication network in the call waiting state (step 200), the communication modem 112 detects the telephone number of the terminal and transmits it to the microcomputer 111 (step 201). At this time, if the user simply dials the telephone number assigned to the communication modem 112 using his terminal, the communication modem 112 detects the caller's telephone number. Alternatively, when the user transmits the short message written by the user to the telephone number assigned to the communication modem 112, the communication modem 112 may receive the caller's telephone number and the message. .

The microcomputer 111 compares the telephone number provided from the communication modem 112 with the telephone number stored in the memory (step 202). If the received telephone number and the telephone number stored in the memory do not match, the communication modem 112 maintains the call waiting state, and if it matches, the operating state of the telematics device 100 is detected (203).

If the telematics apparatus 100 is in operation, an operating state of the vehicle is detected (step 204). If the vehicle is in an operating state (starting is turned on), the communication modem 210 is connected to the telematics device 100 to make a call between the user's terminal and the telematics device 100 (step 205). If the vehicle is in a stopped state (started off state), the telephone number of the telematics center stored in the memory is transmitted to the communication modem 112 to transmit a signal to the telematics center (step 206). By soliciting a service, the telematics center checks the state of the vehicle. At this time, in order to confirm the failure or theft of the vehicle in the telematics center may transmit the location information provided from the position acquisition unit 114 to the telematics center together.

On the other hand, if the operation of the telematics device 100 is stopped, the microcomputer 111 detects the state of the vehicle power 121 through the power monitoring and control unit 113 (207). If the state of the vehicle power 121 is normal, the microcomputer 111 outputs a power operation signal to the power monitoring and control unit 113, and the power monitoring and control unit 113 is a switching unit according to the power operation signal. Operation 120 may be performed to connect the vehicle power source 121 with the power supply 101 of the telematics device 100 to operate the telematics device 100 (step 208).

On the other hand, if the state of the vehicle power source 121 is poor, the position information of the vehicle is provided from the position acquisition unit 114 (step 209), and the telephone number of the telematics center stored in the memory and the position information are communicated. A modem 112 is provided to transmit the location information to the telematics center (step 206). As such, the telematics center checks the position and power state of the vehicle by informing the location information of the vehicle and requesting a service.

In addition, the present invention is to store the location information and route information periodically collected from the position acquisition unit 114 in the memory of the microcomputer 111, if necessary, for example, in case of emergency rescue, accident occurrence, vehicle theft At this time, the location information and the route information may be transmitted to the telematics center through the communication modem 112 to request a service, or may be transmitted to the telematics device 100 to immediately stop the start of the vehicle.
