用于实现远程信息通信终端功率节省模式的设备和方法 Apparatus and method for implementing telematics terminal power saving mode

发明背景1.发明领域本发明涉及用于实现远程信息通信终端功率节省模式的设备和方法,更特别地涉及用于实现远程信息通信终端功率节省模式的设备和方法,该终端运行于功率节省模式,能够在汽车的点火装置关闭时使电池的消耗最小。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to apparatus and methods for implementing the telematics terminal power saving mode, and more particularly to apparatus and methods for implementing remote information communication terminal power saving mode, the terminal is operating in a power save mode possible so that the battery consumption is minimized when the ignition system of the vehicle is turned off.

2.相关技术描述“远程信息通信”,由词“远程通信”和“信息学”构成的复合词,并在信息技术(IT)领域中受到了很大的关注。 2. Description of Related Art "telematics" by the word "telecommunications" and "informatics" constitutes a compound word, and has been a great concern in the information technology (IT) field. 远程信息通信指的是能在运输装置(车辆)移动时提供信息的无线电(无线)数据业务,特别地,远程信息通信能够允许在汽车、飞机、轮船或类似的运输工具中提供电脑,以通过使用无线通信技术、GPS(全球定位系统)、通过互联网把特定信息转换为文本信号或语音信号的技术和其它相关技术来与基站交换信息。 Telematics refers to provide information on the transport means (vehicles) to move the radio (wireless) data services, in particular, telematics can allow the provision of computer in the automotive, aircraft, ships or similar conveyance, by using wireless communication technology, GPS (global positioning system), via the Internet to the specific information into a text signal or a voice signal technology and other related technologies to exchange information with a base station.

特别地,用于汽车的远程信息通信业务通过使用移动通信技术和位置检测技术来为驾驶员实时地提供信息,例如汽车事故、偷窃监测、驾驶路线、交通量和现场信息、比赛或类似信息。 In particular, for automotive telematics be provided through the use of mobile communications technology and position sensing technology as the driver real-time information, such as car accidents, theft monitoring, driving directions, and live traffic information, the game or the like.

例如,用于汽车的远程信息通信业务允许当汽车出现故障时把远程信息通信终端连接到业务中心,允许通过汽车中的电脑监视器接收电子邮件或显示公路线路图,并允许乘客通过安装在后座上的监视器打电脑游戏。 For example, telematics for cars when the car fails to allow the telematics terminal connected to the service center is allowed to receive e-mail, or display through the car in the road map of the computer monitor, and allows passengers to pass after installation seat monitors playing computer games. 此外,因为连接到发动机的电脑记录汽车主要零件的状态,所以远程信息通信业务能够在任何时候通知技工什么零件损坏了和为什么损坏的。 In addition, because the connection to the engine computer records automobile major parts of the state, so telematics can at any time what parts damaged and why the damage notification mechanic.

另外,远程信息通信终端能够允许驾驶员在驾驶过程中通过语音命令使用互联网,并且当驾驶员误锁了车门且他的汽车钥匙仍在车内时也能够允许通过卫星信号打开汽车的门。 In addition, the telematics terminal can allow the driver to drive the process of using the Internet by voice command, and when the driver mistakenly lock the door and his car keys still inside the vehicle can be allowed to open the car door by satellite signals.

图1是示出根据相关技术的远程信息通信终端功率节省模式设备的构造框图。 Figure 1 is a block diagram illustrating configuration saving mode of the device according to telematics terminal power related art.

如其中所示出的,该功率节省模式设备包括NAD(网络接入设备)处理器11,用于通过使用移动通信技术来处理在基站与远程信息通信终端之间的各种呼叫信号,并调制/解调信息信号;用于向NAD处理器11供电的NAD供电单元12;控制单元13,用于与在汽车中提供的控制单元(未示出)通信,并与NAD处理器11通信,以控制远程信息通信终端;时钟振荡单元14,用于给控制单元13和NAD供电单元12提供基准时钟;通信接口单元15,用于控制单元13与在汽车中提供的控制单元之间的通信;主系统供电单元16,用于向包括控制单元13的主系统供电;和保持激活操作的供电单元18,用于向通信接口单元15和通信信号的放大器17供电。 As it is shown wherein the power saving mode device includes a NAD (network access device) processor 11 for use by a mobile communication technology to handle various call signal in the base station and the remote information communication terminal, and modulation / demodulating an information signal; NAD processor 11 is used to supply the NAD power supply unit 12; the control unit 13, provided for the control unit in a vehicle (not shown) of a communication, and communication with the NAD processor 11 to control telematics terminal; clock oscillation unit 14 for the control unit 13 and the power supply unit 12 provides NAD reference clock; a communication interface unit 15, a communication control unit 13 and the control unit provided in the vehicle between; master system power supply unit 16 for supplying power to the system includes a main control unit 13; and a holding activation of the power supply unit 18, 17 for supplying power to the communication interface 15 and the communication unit of the signal amplifier.

通信接口单元15包括CAN(控制器范围网络)物理层接口15a和J1850物理层接口15b,该通信接口单元15是CLASS 2系列通信设备。 The communication interface unit 15 includes a CAN (controller area of the network) physical layer interface J1850 physical layer interface 15a and 15b, the communication interface unit 15 is CLASS 2 series of communications equipment. 主系统供电单元16由信号组合单元19控制,信号组合单元19组合来自外部通信网络(CAN、J1850)的信号,以输出控制信号。 Main system power supply unit 16 is controlled by the signal combination unit 19, the signal combination unit 19 combined signal from an external communication network (CAN, J1850) to output a control signal.

甚至在汽车的点火器关闭之后,远程信息通信终端也应该能够使用有限的电池功率与基站长时间通信。 Even after the car's ignition is switched off, telematics terminal should be able to use the limited battery power for a long time to communicate with the base station. 因此,远程信息通信终端以接收备用功率节省模式工作。 Therefore, telematics terminal to receive backup power saving mode.

在接收备用功率节省模式下,以十分钟的间隔执行操作,由此在汽车的点火器关闭之后,用一分钟从基站接收信号,有九分钟不从基站接收信号。 In the reception standby power saving mode, the operation performed at an interval of ten minutes, whereby after the car's ignition is turned off, a minute signal is received from the base station, there is not receiving signals from the base station nine minutes. 重复执行这样的操作,从而尽最大可能地抑制了功率消耗,并且这样延长了汽车电池或例如远程信息通信终端的电池的其它电力存储设备的寿命。 Repeat this operation so the maximum extent possible to suppress the power consumption, and thus extend the life of a car battery or other power storage device such as a remote information communication terminal of the battery.

现在将简要地解释远程信息通信终端的功率节省模式设备的上述操作。 We will now be briefly explained telematics terminal power saving operation mode of said apparatus.

首先,NAD处理器11从CDMA/PCD基站(未示出)接收当前时间信息,并把接收的信息发送到控制单元13。 First, NAD processor 11 from CDMA / PCD base station (not shown) to receive the current time information, and sends the received information to the control unit 13.

如果汽车的点火器关闭,时钟振荡单元14驱动在控制单元13内的S/W定时器13a,控制单元13根据设置的定时周期性地打开/关闭该设备的部件,用来实现功率节省模式。 If your car's ignition is switched off, the drive clock oscillation unit 14 in the control unit 13 of S / W timer 13a, the control unit 13 based on the timing set periodically opening / closing parts of the device, used to achieve power saving mode. 即,在接收备用状态下,用一分钟驱动控制单元13、NAD处理器11和RF模块(未示出)以接收从基站发射的信号,而对于紧接着的九分钟,仅仅以功率节省模式驱动NAD处理器11、RF模块(未示出)和控制单元13的核心部分。 That is, in the reception standby state, a minute driving control unit 13, NAD processor 11 and the RF module (not shown) to receive signals transmitted from the base station, and followed for nine minutes, only to drive the power save mode NAD processor 11, RF module (not shown) and a control unit 13 of the core part.

如以上所描述的,在实现相关技术远程信息通信终端功率节省模式的设备中,因为定时器是在控制单元中提供的,控制单元、NAD处理器和RF模块在接收备用状态下同时工作,这造成了消耗大量的电流,而汽车的电池容量是有限的。 As described above, in the realization of the related art telematics terminal equipment in the power saving mode, since the timer is provided in the control unit, control unit, NAD processor and an RF module while the reception standby state, which resulting in a large amount of current consumption, and the battery capacity is limited car. 不利的是,由于这个原因,用于实现功率节省模式的所述设备不能长时间工作。 Unfortunately, for this reason, the device for realizing power saving mode does not work for a long time.

发明概要因此,本发明的目的是提供用于实现远程信息通信终端功率节省模式的设备和方法,当安装在汽车内的远程信息通信终端以功率节省模式工作时,该设备和方法能够使在接收备用状态下功率消耗最小。 SUMMARY Accordingly, the present invention is to provide a remote information communication terminal power saving mode of the apparatus and method, when the telematics terminal installed in the vehicle to power saving mode, the device and method enables the reception minimum power consumption in the standby state.

图2是示出根据本发明用于实现远程信息通信终端功率节省模式的设备第一实施例的框图。 Figure 2 is a block diagram showing apparatus of the present invention for achieving the telematics terminal power saving mode according to the first embodiment.

如其中所示出的,用于实现功率节省模式的设备包括用于控制远程信息通信终端的控制单元21;用于处理在远程信息通信终端与基站之间的各种呼叫并调制/解调信息信号的NAD处理器22;用于允许在控制单元21与另一个在汽车内的控制单元(未示出)通信的通信接口单元23;用于分别向NAD处理器22、控制单元21和通信接口单元23供电的供电单元24、25和26;用于驱动在NAD处理器22内的软件定时器22a的时钟振荡器27;和用于把来自通信接口单元23的信号与来自NAD处理器22的功率控制信号结合起来以控制主系统供电单元25的信号组合单元28。 As shown in which, the device for realizing power saving mode comprises means for controlling the information communication terminal remote control unit 21; means for processing the information communication between the remote terminal and the base station, and various call modulation / demodulation information NAD signal processor 22; 21 for allowing the control unit to another control unit in the vehicle (not shown) communicating communication interface unit 23; the NAD processor 22 for respectively, the control unit 21 and a communication interface unit 23 power supply unit 24, 25 and 26; for driving in the NAD processor 22 software timer 22a of clock oscillator 27; and for the signal from the communication interface unit 23 and the processor 22 from NAD combined power control signal to control the main system power supply unit 25 of the signal combination unit 28.

NAD处理器22可以是用于移动通信的调制解调器,并且可以称为MSM(移动站调制解调器)。 NAD processor 22 may be a modem for mobile communication and may be referred to as MSM (Mobile Station Modem).

现在将解释如上述构造的用于实现远程信息通信终端功率节省模式的设备的操作。 Configured as described above will now be explained for a remote information communication terminal apparatus power saving mode of operation.

当在其中有远程信息通信终端的汽车的点火器关闭时,控制单元21被完全关闭,NAD处理器22通过从基站(未示出)发送的时间信息和附属在NAD处理器22上的时钟振荡器27来驱动软件定时器22a。 When including telematics terminal car's ignition is switched off, the control unit 21 is completely closed, NAD processor 22 via the base station (not shown) and subsidiary transmit time information on NAD processor 22 clock oscillation 27 to drive the software timer 22a.

在预定的一段时间(例如,一分钟),NAD处理器22通过使用它的内部软件定时器22a来驱动它自己和RF模块(未示出),以便远程信息通信终端以接收备用状态工作,并在一段预定的时间(例如,九分钟)仅仅驱动NAD处理器22和RF模块(未示出)的核心,以便远程信息通信终端以功率节省模式工作。 In a predetermined period of time (e.g., one minute), NAD processor 22 by using its internal software timer 22a to drive itself and the RF module (not shown), so that the remote information communication terminal to receive the standby mode of operation, and at a predetermined time (e.g., nine minutes) NAD processor 22 and drives only the RF module (not shown) of the core, so that the remote information communication terminal in a power save mode. 即远程信息通信终端能够降低由控制单元21消耗的电流量。 That telematics terminal can be reduced by the amount of current consumed by the control unit 21.

如果远程信息通信终端位于不能从基站获得时间信息的模拟服务区内,远程信息通信终端通过在该远程信息通信终端中提供的GPS(全球定位系统)接收从卫星发送的GPS时间信息,从而驱动软件定时器22a。 If telematics terminal located not get time information from the analog service area of a base station, remote information communication terminal provided by the telematics terminal in GPS (Global Positioning System) receiver GPS time information transmitted from the satellite, thereby driving software timer 22a.
