图 1是本发明所揭示的用户识别***电源管理方法总体结构示意图，如图 1 所示， 用户识别*** 10包括***电源 101、 供电接口 103、 外界能源转换装置 105、 ***启动模块 107、 主控模块 109以及用户识别*** 10内的用电模组。 本 发明中不限定用电模组的数量， 为了便于进行说明， 以三个用电模组， 即如图 1 中所示的模组 1、 模组 2和模组 3为例进行说明。 1 is a schematic diagram showing the overall structure of a power management method for a user identification system according to the present invention. As shown in FIG. 1, the user identification system 10 includes a system power supply 101, a power supply interface 103, and an external energy conversion device. 105.

The working mode is to achieve the purpose of saving power for the user identification system 10. Specifically, the main control module 109 can control the module 1 to operate in the power saving working mode 1, and the control module 2 can work in the power saving working mode 2, and the control module 3 can work in the power saving working mode 3. The control method of the main module 109 for different modules in various power saving modes will be described in detail below.
首先， 现将结合图 2对用户识别*** 10的总体电源供应方式作详细描述。 在图 2中， ***内各模块 201代表了用户识别*** 10内的所有用电的***功能 模块以及主控模块 109, 例如为图 1 中所示的模组 1、 模组 2、 模组 3。 而 203 表示输电线， 输电线 203用于向***内各模块 201供电， ***电源 101、 供电接 口 103 以及外界能源转换装置 105均可向输电线 203提供电流， 使得***内各 模块 201从输电线 203获得电流供应。 First, the overall power supply mode of the subscriber identity system 10 will now be described in detail in conjunction with FIG. In FIG. 2, each module 201 in the system represents all the power system function modules and the main control module 109 in the user identification system 10, for example, the module 1, the module 2, and the module 3 shown in FIG. . And 203 denotes a power transmission line, and the power transmission line 203 is used for supplying power to each module 201 in the system, and the system power supply 101, the power supply interface 103, and the external energy conversion device 105 can supply current to the power transmission line 203, so that each system is provided. Module 201 obtains a current supply from power line 203.
图 3详细描述了供电接口 103的两种实施方式， 如图 3所示， 供电接口 103 可用 USB接口 103a或耳机接口 103b实现， 在 USB接口 103a的实施方式中， USB接口 103a中的电源线可直接连接到输电线 203中， 外部 USB设备可透过 USB接口的方式向***内各模块 201供电， 而 USB接口 103a中的数据线可与 主控模块 109连接， 从而可实现外部 USB设备与用户识别*** 10间的数据传 输。 而在耳机接口 103b的实施方式中， 耳机接口 103b中的电源线直接连接到 输电线 203 , 外部设备可透过耳机接口 103b直接供应电流至输电线 203中， 从 而向***内各模块 201供电。  FIG. 3 illustrates two implementations of the power supply interface 103. As shown in FIG. 3, the power supply interface 103 can be implemented by using the USB interface 103a or the earphone interface 103b. In the implementation of the USB interface 103a, the power cable in the USB interface 103a can be Directly connected to the power line 203, the external USB device can supply power to each module 201 in the system through the USB interface, and the data line in the USB interface 103a can be connected with the main control module 109, thereby realizing external USB devices and users.

In the embodiment of the headphone jack 103b, the power cord in the headphone jack 103b is directly connected to the power line 203, and the external device can directly supply current to the power line 203 through the headphone jack 103b, thereby supplying power to the modules 201 in the system.
图 4则详细描述了图 2中的外界能源转换装置 105供应电流到输电线 203 的实施方式。 在图 4中， 外界能源转换装置 105例如可为太阳能电池板、 风力 发电机、 温差发电机、 电磁波发电机或压电转换装置， 其可将太阳能、 风能、 温差能、 电磁波能或振动能和形变能中的任意一种转换为交变电流， 所转换而 成的交变电流可透过整流电路 401转换成直流电流， 从而向输电线 203提供直 流电流。 采用外界能源转换装置 105为用户识别*** 10提供电源的方法可解决 在野外安装的用户识别设备不能长时间工作的问题。  Figure 4 illustrates in detail the embodiment in which the ambient energy conversion device 105 of Figure 2 supplies current to the power line 203. In FIG. 4, the external energy conversion device 105 can be, for example, a solar panel, a wind turbine, a thermoelectric generator, an electromagnetic wave generator, or a piezoelectric conversion device, which can combine solar energy, wind energy, temperature difference energy, electromagnetic wave energy, or vibration energy. Any one of the deformation energies is converted into an alternating current, and the converted alternating current can be converted into a direct current by the rectifying circuit 401 to supply a direct current to the power line 203. The method of providing power to the subscriber identity system 10 using the external energy conversion device 105 solves the problem that the user identification equipment installed in the field cannot operate for a long time.
现将结合图 5-8对本发明用户模组的电源管理方法进行说明。以图 1中主控 模块 109控制模组 1在省电工作模式 1下工作的方法为例作详细介绍。 本发明 中， 模组 1 可以是电机、 电磁铁、 电磁阀、 电热设备、 光电门、 压电设备等设 备中的任意一种， 是在用户识别*** 10对用户特征识别完成后为该名用户开门 动作所需的动力驱动设备， 这些动力驱动设备会受控于主控模块 109, 由主控模 块 109控制其实现转动、 闭合或开启的动作。 现有用户识别***中， 上述动力 驱动设备在完成转动、 闭合或开启的动作之后， 并不会马上停止对这些动力驱 动设备的电供应， 而是会有一定延时， 从而使得这些动力驱动设备在完成自己 的任务后还要耗费一部分电能， 以电机为例， 如图 5 中所示， 假设电机在工作 电压下完成驱动锁芯开启所需的转动要用到的时间是 3秒， 但是在实际工作中， 由于缺乏保护机制， 使得该电机在工作电压下工作了 3 秒后仍保持通电状态， 导致电机只是有效工作了 3 秒， 而剩下时间该电机会受到工作电压的驱动但是 实际上并没有作任何的转动动作， 而在这剩下时间中， 该电机耗费的功率其实 很大。 如图 5所示， 在 0-3s期间电机的工作电流为 0.1A, 而在 3s后的时间段中 电机的电流上升为 1A,因此有必要消除这剩下的 3s后的时间段内所产生的较高 功耗。 对此， 本发明中， 对模组 1而言， 主控模块 109可让其工作在省电工作 模式 1下： 先对所要使用的模组 1(例如为动力驱动设备)提供其工作电压， 使其 在工作电压下工作； 再测试其在工作电压下完成工作所需的实际时间； 将该时 间保存以提供给主控模块 109。现在继续以电机为例对上述发明方法作进一步的 描述： 开发人员首先估算出电机完成工作需要转动的角度， 对电机施加工作电 压并开始计时， 在电机转动完所需转动的角度后， 停止工作电压的供应并停止 计时， 这时所录得的时间段正是电机的有效工作时间， 开发人员将该有效工作 时间烧录到主控模块 109的固件中或保存到存储设备中， 主控模块 109可随时 获得此有效工作时间， 以对电机的有效时间进行精确的驱动控制。 进一步地， 而获得不同型号的动力驱动设备的工作电压-有效工作时间对应关系， 因此形成 了图 6中的设备型号-工作电压-有效工作时间对照表， 这个设备型号-工作电压- 有效工作时间对照表记录了某一型号的动力驱动设备的工作电压以及有效工作 时间， 将这个表录入到主控模块 109 的固件或存储设备中， 以供主控模块 109 随时查阅， 例如， 主控模块 109透过***检测模块（于下文中会作详细介绍） 检测到当前所使用的动力驱动设备是一电磁阀， 因此在固件或存储器中查询得 该电磁阀所对应的工作电压 8v和有效工作时间 0.35s,从而只对电磁阀供应 0.35s 的 8v 电压， 进而避免了无意义的供电。 通过上述方法， 使得用户识别*** 10 所使用的动力驱动设备能够在完成有效的工作后马上关闭， 而不会造成额外的 电能浪费。 是， 对于没有安装稳压模块的用户识别*** 10来说， 施加到动力驱动设备的工 作电压会由于电量的不断衰耗而逐渐降低， 在图 7 中， 显示了由于动力驱动设 备的工作电压 U 不断降低而使得动力驱动设备的工作时间 T 不断增加的曲线 T=f ( U )。 其中， T为动力驱动设备的有效工作时间， U为动力驱动设备的工 作电压， ^据图 7, 可知这个动力驱动设备的理想工作电压为 6v, 于理想工作 电压 6v下其有效工作时间为 0.2s, 即在 6v的工作电压下其需要工作 0.2s就能 完成工作， 但随着电量的衰耗， 其电压降到 5.5v, 这时该动力驱动设备在 5.5v 的电压下需要 0.28s来完成工作， 当电压降到 5v时， 则需要 0.46s来完成工作， 由此可推知， 由于电压的下降， 动力驱动设备的有效工作时间会逐渐增大。 因 此， 在实际应用中， 必须根据电压的变化而调整工作时间， 否则会出现以下的 不利的结果： 举电磁阀为例， 在图 6中查得当前施加的工作电压为 8v, 但若系 统的电量不足， 结果其电压不能维持在 8v, 而是下降到 6.5v,但是主控模块 109 查得其在 8v下的有效工作时间是 0.35s, 因此只是供应 8v 长达 0.35s的时间， 但是实际上电磁阀是在小于 8v 的电压 6.5v下工作的， 0.35s的电源供应时间其 并不能使得电磁阀完成工作。 对此， 本发明提供一种如下所述的改良方法： 如 图 8所示， 开发人员可在实验中测试出各种动力驱动设备在不同的工作电压下 的有效工作时间， 并将这些实验数据以函数形式归纳为 T=f ( U ), 其中 U为工 作电压， T为有效工作时间， 不同的动力驱动设备具有不同的工作电压-有效工 作时间函数关系式， 例如电机具有 T= ( U ) 的函数关系式， 光电门具有 T=f2 The power management method of the user module of the present invention will now be described with reference to FIGS. 5-8. The method in which the main control module 109 of FIG. 1 controls the module 1 to operate in the power saving operation mode 1 is described in detail as an example. In the present invention, the module 1 may be any one of a motor, an electromagnet, a solenoid valve, an electric heating device, a photoelectric gate, a piezoelectric device, etc., and is the user after the user identification system 10 identifies the user feature. The power driving devices required for the door opening action are controlled by the main control module 109, and the main control module 109 controls the actions of turning, closing or opening. In the existing user identification system, after the power driving device completes the action of turning, closing or opening, the power supply to the power driving devices is not immediately stopped, but there is a certain delay, thereby making the power driving devices After completing his own task, it takes a part of the power. Taking the motor as an example, as shown in Figure 5, it is assumed that the motor takes 3 seconds to complete the rotation required to drive the cylinder to open at the operating voltage, but In actual work, due to the lack of protection mechanism, the motor remains energized after working for 3 seconds at the working voltage. As a result, the motor only works effectively for 3 seconds, and the motor is driven by the operating voltage for the rest of the time, but it does not actually perform any turning action. In the remaining time, the power consumed by the motor is actually very large. As shown in Fig. 5, the operating current of the motor is 0.1A during 0-3s, and the current of the motor rises to 1A in the period after 3s, so it is necessary to eliminate the time period after the remaining 3s. Higher power consumption. In this regard, in the present invention, for the module 1, the main control module 109 can operate in the power saving operation mode 1: firstly, the working voltage of the module 1 to be used (for example, a power driving device) is provided. It is operated at the operating voltage; it is then tested for the actual time required to complete its operation at the operating voltage; this time is saved for supply to the master module 109. Now continue to use the motor as an example to further describe the above invention method: The developer first estimates the angle at which the motor needs to be rotated, applies the working voltage to the motor and starts timing, and stops working after the motor has rotated the required angle of rotation. The voltage is supplied and the timing is stopped. At this time, the recorded time period is the effective working time of the motor. The developer burns the effective working time to the firmware of the main control module 109 or saves it to the storage device. The main control module 109 This working time can be obtained at any time to provide precise drive control of the effective time of the motor. Further, the working voltage-effective working time correspondence relationship of different types of power driving equipment is obtained, thereby forming a device model-operating voltage-effective working time comparison table in FIG. 6, the equipment model-operating voltage-effective working time The comparison table records the working voltage and effective working time of a certain type of power driving device, and the table is entered into the firmware or storage device of the main control module 109 for the main control module 109 to consult at any time. For example, the main control module 109 Through the system detection module (described in detail below), it is detected that the currently used power drive device is a solenoid valve, so the operating voltage corresponding to the solenoid valve is 8v and the effective working time is 0.35 in the firmware or the memory. s, so that only 8v voltage of 0.35s is supplied to the solenoid valve, thereby avoiding meaningless power supply. By the above method, the power driving device used by the user identification system 10 can be turned off immediately after the effective work is completed without incurring additional power waste. Yes, for the user identification system 10 in which the voltage stabilizing module is not installed, the operating voltage applied to the power driving device is gradually reduced due to the continuous loss of power, and in Fig. 7, the power driving is shown. The standby operating voltage U is continuously lowered so that the operating time T of the power-driven device is continuously increasing by T=f ( U ). Among them, T is the effective working time of the power drive equipment, U is the working voltage of the power drive equipment. According to Figure 7, the ideal working voltage of this power drive equipment is 6v, and the effective working time is 0.2 under the ideal working voltage 6v. s, that is, it needs 0.2 s to work at 6v working voltage, but with the power consumption, its voltage drops to 5.5v, then the power drive device needs 0.28s at 5.5v. When the voltage is reduced to 5v, 0.46s is required to complete the work. It can be inferred that the effective working time of the power driving device will gradually increase due to the voltage drop. Therefore, in practical applications, the working time must be adjusted according to the change of voltage, otherwise the following unfavorable results will occur: Take the solenoid valve as an example. In Figure 6, the current applied operating voltage is 8v, but if the system The battery is not enough. As a result, the voltage cannot be maintained at 8v, but it drops to 6.5v. However, the master module 109 finds that its effective working time at 8v is 0.35s, so it only supplies 8v for 0.35s, but the actual time. The upper solenoid valve operates at a voltage of 6.5V less than 8v, and the power supply time of 0.35s does not allow the solenoid valve to complete its operation. In this regard, the present invention provides an improved method as described below: As shown in FIG. 8, the developer can test the effective working time of various power driving devices under different working voltages in experiments, and the experimental data. It is summarized as a function form T=f ( U ), where U is the working voltage and T is the effective working time. Different power drive devices have different working voltage-effective working time function relationships, for example, the motor has T= ( U ) The functional relationship, the photogate has T=f 2
( U ) 的函数关系式， 电磁阀具有 T=f3 ( U ) 的函数关系式， 将不同设备对应的 工作电压 -有效工作时间函数关系烧录到主控模块 109的固件或存储在存储模块 中，让主控模块 109可随时查阅到设备型号 -工作电压-函数对应关系，举例来说， 当主控模块 109检测到当前所用的动力驱动设备为电机， 并透过***检测模块The functional relationship of ( U ), the solenoid valve has a functional relationship of T=f 3 ( U ), and the operating voltage-effective working time function relationship corresponding to different devices is burned to the firmware of the main control module 109 or stored in the storage module. In the middle, the main control module 109 can refer to the device model-operating voltage-function correspondence at any time. For example, when the main control module 109 detects that the currently used power driving device is a motor, and passes through the system detecting module.

The main control module 109 introduced above controls the length of the power supply device voltage supply time. The method can be implemented by any conventional technology in the art, for example, by setting a switch that can be controlled by the main control module 109 between the power source and the power driving device, and setting the switch through the main control module 109 in a software manner. / Breaking time, thereby achieving the technical effect of controlling the power supply device voltage supply time by the main control module 109 as described above. The manner in which the main control module 109 described above controls the voltage supply of the power driving device can be any conventional technology in the art, for example, by setting a transformer module between the power source and the power driving device, through the main The control module 109 selects the output voltage of the transformer module in a software manner, thereby achieving the technical effect of controlling the voltage supply size of the power drive device by the main control module 109 as described above.
另外， 对于动力驱动设备而言， 也可利用一电流检测单元来实现省电功能， 具体实现方式如下： 在动力驱动设备上串接一电阻， 并将一电压计与上述电阻 并接， 主控模块 109 随时获得电压计的测量值， 从而将电压测量值与电阻值作 相除以获得电流值， 若电流值大于或少于某一阈值， 则主控模块 109会停止动 力驱动设备的电源供应， 从而达到了省电的效果。  In addition, for the power driving device, a current detecting unit can also be used to realize the power saving function, and the specific implementation manner is as follows: a resistor is connected in series to the power driving device, and a voltmeter is connected with the resistor, the main control The module 109 obtains the measured value of the voltmeter at any time, thereby dividing the voltage measurement value and the resistance value to obtain a current value.

现将结合图 9对图 1中主控模块 109控制模组 2在省电工作模式 2下工作 的方法作详细介绍。 对模组 2而言， 主控模块 109可让其工作在省电工作模式 2 下， 其中模组 2可以是存储模块、 用户识别模块、 语音提示模块、 通信模块、 语音对比模块、 加密模块、 ***检测模块以及用户界面模块等设备中的一种， 其中上述这些模块中的任意一种是用户识别*** 10的常用模块， 并且上述的模 块并不限定于在本发明中使用， 它们可在任何现有技术中使用， 本发明只是提 供一种实施于其上的供电控制方法。  The method in which the control module 2 of the main control module 109 in Fig. 1 operates in the power saving mode 2 will now be described in detail with reference to FIG.

为了更好地介绍本发明所提供的省电工作模式 2, 现将对存储模块、 用户识 别模块、 语音提示模块、 通信模块、 语音对比模块、 加密模块、 ***检测模块 以及用户界面模块的功能逐一作出筒单描述： 存储模块可为用户识别*** 10提 供存储空间， 用以存储相关信息， 其可利用存储芯片、 TF卡、 SD卡、 U盘以及 例如网络空间的远程存储空间来实现； 用户识别模块接收用户的特征信息， 并 将注册好的特征信息转换成特征码形式记录， 当任何用户登陆时， 再次输入特 征信息， 用户识别模块将特征信息转换成特征码， 将此特征码与原来所注册时 所记录的特征码比对， 然后将比对结果反馈给主控模块 109, 而主控模块 109可 根据结果进行相应的控制动作； 语音提示模块用于提示用户在操作设置设备时 作何种操作； 通信模块用于使得用户识别*** 10与外界进行通讯； 语音对比模 块与用户识别模块功能相似， 区别在于语音对比模块是根据用户的声音作为特 征信息； 加密模块用于对用户识别*** 10内的数据进行加密操作； ***检测模 块在启动后可检测用户识别*** 10内所有模块的设备型号、 工作电压、 工作状 态， 并且能够随时响应主控模块 109 的要求而对***内某一特定模块进行设备 型号、 电压检测； 用户界面模块向用户提供操作界面， 如向用户列出选择菜单， 提供按钮让用户选择等， 其可用触摸屏、 按钮、 LCD显示器等方式中的一种或 任意组合实现。 In order to better introduce the power saving working mode 2 provided by the present invention, the functions of the storage module, the user identification module, the voice prompt module, the communication module, the voice comparison module, the encryption module, the system detection module, and the user interface module are respectively one by one. Making a description of the cartridge: The storage module can provide storage space for the user identification system 10 for storing related information, which can be realized by using a memory chip, a TF card, an SD card, a USB flash drive, and a remote storage space such as a network space; The module receives the feature information of the user, and converts the registered feature information into a feature code form record. When any user logs in, the feature information is input again, and the user identification module converts the feature information into a feature code, and the feature code is compared with the original code. When registering The recorded feature code is compared, and then the comparison result is fed back to the main control module 109, and the main control module 109 can perform corresponding control actions according to the result; the voice prompting module is used to prompt the user to perform operations when operating the setting device. The communication module is configured to enable the user identification system 10 to communicate with the outside world; the voice comparison module functions similarly to the user identification module, except that the voice comparison module is based on the user's voice as feature information; the encryption module is used to identify the user within the system 10 The data is encrypted. The system detection module can detect the device model, working voltage, and working state of all modules in the user identification system 10 after startup, and can perform equipment on a specific module in the system in response to the requirements of the main control module 109. Model, voltage detection; The user interface module provides an operation interface to the user, such as listing a selection menu to the user, providing a button for the user to select, etc., which can be implemented by one or any combination of a touch screen, a button, an LCD display, and the like.
如图 9中所示， 在省电工作模式 2中， 主控模块 109可控制模组 2的电源 供应， 当需要使用模组 2时， 主控模块 109就控制***电源 101对模组 2供电， 当暂时不需要使用模组 2时， 主控模块 109就会使得***电源 101不对模组 2 进行供电， 从而达到省电的效果。 具体实现为： 可在***电源 101与模组 2之 间设置一开关 901 , 于此采用***电源 101供电仅是为了方便说明， 实际上可以 使用***电源 101、 供电接口 103、 外界能源转换装置 105中的一种或任意组合 对模组 2进行供电， 而模组 2可以是存储模块、 用户识别模块、 语音提示模块、 通信模块、 语音对比模块、 加密模块、 ***检测模块以及用户界面模块中的一 种。 主控模块 109可控制开关 901的开启和关闭， 从而控制模组 2的供电状态， 而模组 2在完成工作后可发送一信号至主控模块 109,而主控模块 109在接收到 这个信号后就闭合开关 901 , 从而停止对模组 2进行供电， 而在用户识别*** 10需要使用模组 2时， 主控模块 109可预测到将要使用到模组 2, 从而打开开 关 901 , 因此模组 2获得电源供应， 而得以正常工作。 在这种工作模式下， 用户 识别*** 10可在不需要使用模组 2时就停止电能供应， 而在需要使用模组 2时 再对其进行电能供应， 这样的话可避免在不需要使用模组 2 时却仍要对其进行 一定的电量供应的情况发生。  As shown in FIG. 9, in the power saving mode 2, the main control module 109 can control the power supply of the module 2. When the module 2 is needed, the main control module 109 controls the system power supply 101 to supply the module 2. When the module 2 is not needed for a while, the main control module 109 causes the system power supply 101 to not supply power to the module 2, thereby achieving the power saving effect. The specific implementation is as follows: A switch 901 can be disposed between the system power supply 101 and the module 2, and the system power supply 101 is used for power supply only for convenience of description. In fact, the system power supply 101, the power supply interface 103, and the external energy conversion device 105 can be used. The module 2 can be powered by one or any combination, and the module 2 can be a storage module, a user identification module, a voice prompt module, a communication module, a voice comparison module, an encryption module, a system detection module, and a user interface module. One. The main control module 109 can control the opening and closing of the switch 901 to control the power supply state of the module 2, and the module 2 can send a signal to the main control module 109 after completing the work, and the main control module 109 receives the signal. After the switch 901 is closed, the power supply to the module 2 is stopped. When the user identification system 10 needs to use the module 2, the main control module 109 can predict that the module 2 will be used, thereby opening the switch 901, so the module 2 Get the power supply and get it working. In this mode of operation, the user identification system 10 can stop the power supply when the module 2 is not needed, and then supply the power when the module 2 is needed, so that the module can be avoided. At 2 o'clock, it still needs to supply a certain amount of electricity.
为了更深刻地描述本发明的用户识别*** 10所采用的省电工作模式 2, 于 下文中以模组 2为一存储模块为例对省电工作模式 2进行进一步的详细说明。 当***启动模块 107启动主控模块 109后， 主控模块 109启动自检程序， 这时 用户识别*** 10中的所有用电模块均处于通电状态， 对于工作在省电工作模式 2中的模组 2 (包括存储模块） 而言， 主控模块 109控制开关 901闭合， 从而对 存储模块提供电源， 在自检程序完成后， 若主控模块 109发现不用对存储模块 进行读取或写入的操作， 这时主控模块 109断开开关 901 ,从而停止对存储模块 的电源供应， 而当主控模块 109在运行时发现需要进行对存储模块读取或写入 的操作， 例如需要调用一要对存储模块的硬件地址进行读写操作的子程序， 这 时主控模块 109会通过预先设定好的软件方式而在进行读写操作的子程序运行 之前运行另一子程序， 该另一子程序可使得主控模块 109控制开关 901 闭合， 从而使得电源供应至存储模块， 于是存储模块恢复正常供电， 这时主控模块 109 会继续调用对存储模块进行读取或写入操作的子程序， 而对存储模块进行读写 操作， 而在读写操作完毕后，存储模块向主控模块 109发送一读 /写完毕的信号， 使得主控模块 109在捕获此信号后可通过软件方式调用一可使得主控模块 109 控制开关 901打开的子程序， 从而打开开关 901进而停止对存储模块进行电供 应。 然而， 如前所述， 模组 2并不限定于存储模块， 其可为用户识别模块、 语 音提示模块、 通信模块、 语音对比模块、 加密模块以及用户界面模块中的任意 一种， 用户识别模块、 语音提示模块、 通信模块、 语音对比模块、 加密模块以 及用户界面模块均可与主控模块 109进行通信以在本身处于空闲状态时告知主 控模块 109自己处于空闲状态， 实现方法有 UART、 SPL I2C等通信方式。 In order to more deeply describe the power saving mode 2 employed by the subscriber identity system 10 of the present invention, The power saving mode 2 will be further described in detail below by taking the module 2 as a storage module as an example. After the system startup module 107 starts the main control module 109, the main control module 109 starts the self-test program, at which time all the power modules in the user identification system 10 are in the power-on state, and the modules working in the power-saving working mode 2 2 (including the storage module), the main control module 109 controls the switch 901 to be closed, thereby providing power to the storage module. After the self-test program is completed, if the main control module 109 finds that the storage module is not to be read or written, At this time, the main control module 109 turns off the switch 901, thereby stopping the power supply to the storage module, and when the main control module 109 is running, it is found that the operation of reading or writing to the storage module is required, for example, it is necessary to call a pair. The subroutine of the storage module's hardware address for reading and writing operations, at this time, the main control module 109 runs another subroutine before the subroutine for reading and writing operations by using a preset software mode, and the other subroutine The main control module 109 can be caused to control the switch 901 to be closed, so that the power supply is supplied to the storage module, and the storage module resumes normal power supply. At this time, the main control module 109 The subroutine for reading or writing to the memory module is continuously called, and the memory module is read and written, and after the read and write operation is completed, the storage module sends a read/write signal to the main control module 109. After the main control module 109 captures the signal, a subroutine that can cause the main control module 109 to control the opening of the switch 901 can be invoked by software, thereby opening the switch 901 and stopping the electrical supply of the storage module. However, as described above, the module 2 is not limited to the storage module, and may be any one of a user identification module, a voice prompt module, a communication module, a voice comparison module, an encryption module, and a user interface module, and the user identification module. The voice prompt module, the communication module, the voice comparison module, the encryption module, and the user interface module can communicate with the main control module 109 to notify the main control module 109 that it is in an idle state when it is in an idle state, and the implementation method includes UART and SPL. Communication methods such as I2C.
但是， 对于一些需要时常工作的用电模组而言， 本发明所揭示的省电工作 模式 2并不适用， 例如***时钟模块， 其需要一直发出时钟信号， 若***时钟 模块停止发出时钟信号， 将会导致整个用户识别*** 10不工作。 对此， 本发明 进一步提供省电模式 3。 现将详细介绍省电工作模式 3, 对于某些用电模组， 例 如模组 3而言， 会设定高功耗工作模式和低功耗工作模式， 在模组 3不工作或 处于待机状态时， 会处于低功耗模式， 而当模组 3工作时， 会处于高功耗模式， 即： 模组 3 随本身工作状态的变化而在低功耗模式和高功耗模式之间切换， 达 到省电的效果。 而与本发明所揭示的省电工作模式 2相比， 在省电工作模式 3 中， 当模组 3 不工作或处于待机状态时， 会处于低功耗模式， 会消耗一部分电 能， 而在本发明所揭示的省电工作模式 2中， 当模组 2不工作时， 其电源会被 自动切断， 从而不会消耗电能。 例如， ***时钟模块适合于在低功耗模式和高 功耗模式间切换， 在不需要大量运算时仅发出低频率的时钟信号， 而在需要作 出大量运算时发出高频率的时钟信号， 从而达到省电的效果。 因此本发明所揭 示的省电工作模式 2可与高功耗模式和低功耗模式切换方法针对不同的用电模 组配合适用， 根据不同用电模组的不同工作方式来相应提供不同的省电模式控 制， 从而达到省电的效果。 However, for some power modules that need to work frequently, the power saving mode 2 disclosed in the present invention is not applicable. For example, the system clock module needs to always issue a clock signal. If the system clock module stops issuing a clock signal, This will cause the entire user identification system 10 to not work. In this regard, the present invention further provides a power saving mode 3. The power saving mode 3 will be described in detail. For some power modules, such as module 3, a high power mode and a low power mode are set, and module 3 is not working or in standby. When in the low power mode, when the module 3 is working, it will be in the high power mode, that is, the module 3 switches between the low power mode and the high power mode as the working state changes. Da To the effect of saving electricity. Compared with the power-saving working mode 2 disclosed in the present invention, in the power-saving working mode 3, when the module 3 is not working or in the standby state, it will be in a low-power mode, and a part of the power will be consumed. In the power saving operation mode 2 disclosed by the invention, when the module 2 is not in operation, its power source is automatically cut off, so that no power is consumed. For example, the system clock module is suitable for switching between a low power mode and a high power mode, and only emits a low frequency clock signal when a large amount of operations are not required, and a high frequency clock signal when a large number of operations are required. The effect of power saving. Therefore, the power-saving working mode 2 disclosed by the present invention can be applied to different power-consuming modules in combination with the high-power mode and the low-power mode switching method, and different provinces are provided according to different working modes of different power modules. Electrical mode control to achieve power saving.
