节能遥控控制模块及控制方法Energy-saving remote control control module and control method

技术领域technical field

本发明涉及无线遥控控制领域，特别是一种由蓄电池供电的遥控控制模块及控制方法。The invention relates to the field of wireless remote control, in particular to a remote control module and a control method powered by a battery.

背景技术Background technique

长久以来，无论工业生产还是居民消费场合，经常见到无线遥控设备或玩具，其内部所安装的遥控接收模块很多都是由各类蓄电池供电。For a long time, no matter in industrial production or residential consumption occasions, wireless remote control equipment or toys are often seen, and many of the remote control receiving modules installed inside are powered by various types of batteries.

使用过程中，由于无线接收模块需要时刻保持监听状态，整个电路系统会持续消耗电能。在一些使用场合由于用户疏忽等原因没能及时关机的情况下，整个系统有可能在很短的时间内消耗掉蓄电池的电能，从而造成遥控失控的状态。During use, since the wireless receiving module needs to keep listening at all times, the entire circuit system will continue to consume power. In some occasions where the user fails to shut down due to negligence and other reasons, the entire system may consume the power of the battery in a very short period of time, resulting in a state of remote control out of control.

上述问题在通用动力产品行业显得更为明显，因为启动电池除了需要承担供电给遥控控制模块的同时还需要承担起动发动机组的功能，一旦使用人员关机没有切断遥控模块电源，短则2-3天，长则1-2周的时间，机组就可能因为电池馈电造成不能正常遥控启动。The above problem is even more obvious in the general dynamic product industry, because the starting battery needs to undertake the function of starting the engine block in addition to supplying power to the remote control module. , as long as 1-2 weeks, the unit may not be able to start normally due to battery feeding.

针对上述问题，目前市场上，具有遥控功能的通用动力产品如汽柴油发电机组，其启动电池基本还是使用大容量的铅酸蓄电池，而不带遥控功能的机组，很多已经切换成了小容量的锂电池，而即使大容量的铅酸蓄电池也仅仅是把遥控模块的待机时间从2-3天延长到1-2周，延时效果不明显，而且是依赖增大电池容量来实现，并且带来了增加了成本、不够环保等问题。In view of the above problems, at present, the general power products with remote control function such as gasoline and diesel generator sets on the market basically still use large-capacity lead-acid batteries for their starting batteries, and many units without remote control function have been switched to small-capacity ones. Lithium batteries, and even large-capacity lead-acid batteries only extend the standby time of the remote control module from 2-3 days to 1-2 weeks, the delay effect is not obvious, and it is achieved by increasing the battery capacity, and with There are problems such as increased cost and insufficient environmental protection.

为了实现低功耗的目的，现有技术中还存在若干其他方案，例如：In order to achieve the purpose of low power consumption, there are several other solutions in the prior art, such as:

专利号为的中国专利公开了低功耗数字信号无线门铃，包括电池，接收输出信号发声的扬声器，一个超再生接收数字信放大电路，接收来自天线的信号；一个数字信号放大整形电路，对超再生接收数字信放大电路输出信号进行放大整形；一个数字信号解码电路，对数字信号放大整形电路输出的数字信号进行解码；一个音乐触发电路，接收数字信号解码电路的信号，并根据其信号进行触发而输出音乐信号；所述的电池，为数字信号放大整形电路、数字信号解码电路、音乐触发电路、扬声器提供电源；所述的超再生接收数字信放大电路与电池之间设有开关电路，所述的开关电路的控制端接于数字信号解码电路，数字信号解码电路输出数字信号至开关电路的控制端。这样，超再生接收数字信放大电路处于间断工作状态，降低了部分功耗，但解码电路、音乐触发电路、扬声器等电路或元件还是直接连接于电池，还是会一直产生待机功耗。The Chinese patent with the patent number of discloses a low-power digital signal wireless doorbell, including a battery, a speaker that receives the output signal and sounds, a super-regenerative receiving digital signal amplifying circuit, which receives the signal from the antenna; a digital signal amplifying and shaping circuit. Regenerate and receive the output signal of the digital signal amplifying circuit to amplify and shape it; a digital signal decoding circuit decodes the digital signal output by the digital signal amplifying and shaping circuit; a music trigger circuit receives the signal of the digital signal decoding circuit and triggers according to its signal And output music signal; the battery provides power for the digital signal amplifying and shaping circuit, the digital signal decoding circuit, the music trigger circuit, and the speaker; the super-regenerative receiving digital signal amplifying circuit and the battery are provided with a switch circuit, so The control terminal of the switch circuit is connected to the digital signal decoding circuit, and the digital signal decoding circuit outputs the digital signal to the control terminal of the switch circuit. In this way, the super-regenerative receiving digital signal amplifying circuit is in an intermittent working state, which reduces part of the power consumption, but the decoding circuit, music trigger circuit, speaker and other circuits or components are still directly connected to the battery, which will always generate standby power consumption.

专利号为201110066162.1的专利提供了一种超低功耗的无线遥测遥控系统和方法，是让受控端平常处于一种周期性睡眠苏醒后监听信号一瞬间的超低功耗状态。当需要向受控端发送工作指令时，控制端将在一段短的时间内连续不间断向受控端发射指令信号，受控端在苏醒的瞬间，先仅只接收1个或有限几个比特位的数据信号并核对其射频特征，特别是扩频编码特征。只有在射频特征吻合后，才延时接收并解析整个数据信号包。上述方案能够大幅降低受控端功耗。但上述方案的应用场景相对复杂，系统组成部分比较多，并且信号的接收判断方法较为复杂，且仅对受控端进行了低功耗控制，具体是单片机或GPS等设备，未提及对其他耗电模块进行低功耗控制。The patent No. 201110066162.1 provides an ultra-low power consumption wireless telemetry and remote control system and method, which is to keep the controlled terminal in a state of ultra-low power consumption in which the signal is monitored for a moment after periodic sleep and waking up. When it is necessary to send a work command to the controlled end, the control end will continuously transmit command signals to the controlled end in a short period of time, and the controlled end will only receive 1 or a limited number of bits at the moment of waking up. data signal and check its radio frequency characteristics, especially the spread spectrum coding characteristics. Only after the radio frequency characteristics are matched, the entire data signal packet is received and analyzed with a delay. The above solution can greatly reduce the power consumption of the controlled end. However, the application scenarios of the above solutions are relatively complex, the system has many components, and the method for judging the reception of signals is relatively complex, and only the controlled end is controlled with low power consumption, specifically the microcontroller or GPS and other devices. The power consumption module performs low power consumption control.

有益效果：Beneficial effects:

由以上技术方案可知，本发明的技术方案提供了一种节能遥控控制模块，该模块通过在耗电模块和供电模块之间设置一数字控制开关，且该数字控制开关受控于MCU，使得数字控制开关实现了关断与导通状态的切换，使得当数字控制开关的关断状态下，耗电模块中仅有MCU处于低功耗状态，其他组件处于零功耗状态，具体的，维持上述整个模块正常工作的重要组件-MCU本身，在低功耗状态下通过并联的电容维持运转，电容内的电量在每次MCU恢复正常功耗状态时得以充电，电容的电量在每次充电后足以维持下一个低功耗状态的正常运行；It can be seen from the above technical solutions that the technical solution of the present invention provides an energy-saving remote control control module, which is provided by a digital control switch between the power consumption module and the power supply module, and the digital control switch is controlled by the MCU, so that the digital control switch is controlled by the MCU. The control switch realizes the switching between the off and on states, so that when the digital control switch is off, only the MCU in the power-consuming module is in a low-power state, and other components are in a zero-power state. Specifically, maintain the above An important component for the normal operation of the entire module - the MCU itself, is maintained in a low-power state through a parallel capacitor. The power in the capacitor is charged every time the MCU returns to the normal power-consumption state, and the power of the capacitor is sufficient after each charge. maintain normal operation in the next low-power state;

具体实施方式Detailed ways

为了更了解本发明的技术内容，特举具体实施例并配合所附图式说明如下。In order to better understand the technical content of the present invention, specific embodiments are given and described below in conjunction with the accompanying drawings.

在本公开中参照附图来描述本发明的各方面，附图中示出了许多说明的实施例。本公开的实施例不必定意在包括本发明的所有方面。应当理解，上面介绍的多种构思和实施例，以及下面更加详细地描述的那些构思和实施方式可以以很多方式中任意一种来实施，这是因为本发明所公开的构思和实施例并不限于任何实施方式。另外，本发明公开的一些方面可以单独使用，或者与本发明公开的其他方面的任何适当组合来使用。Aspects of the invention are described in this disclosure with reference to the accompanying drawings, in which a number of illustrative embodiments are shown. Embodiments of the present disclosure are not necessarily intended to include all aspects of the invention. It should be understood that the various concepts and embodiments described above, as well as those described in greater detail below, can be implemented in any of a number of ways, as the concepts and embodiments disclosed herein do not limited to any implementation. Additionally, some aspects of the present disclosure may be used alone or in any suitable combination with other aspects of the present disclosure.

本实施例具体是一种改善遥控控制模块在待机状态下的耗电情况的方案，通过预设在MCU6中的软件程序和遥控控制模块的硬件电路设计两方面结合来实现。软件程序预先设定MCU6处于间断的低功耗状态和正常功耗状态，低功耗状态时，节能遥控控制模块整体耗电微弱，因此只要低功耗状态时间设置合理，同时兼顾节能和正常操作，就能最大限度的减小耗电。同时，硬件电路设计也同样进行节能考虑，在MCU6处于低功耗状态下时，供电模块1处于零功耗，节能效果好。This embodiment is specifically a solution for improving the power consumption of the remote control module in the standby state, which is realized by combining the software program preset in the MCU6 and the hardware circuit design of the remote control module. The software program pre-sets the MCU6 to be in intermittent low power consumption state and normal power consumption state. In the low power consumption state, the overall power consumption of the energy-saving remote control module is weak, so as long as the time setting of the low-power consumption state is reasonable, both energy saving and normal operation are taken into account. to minimize power consumption. At the same time, the hardware circuit design also considers energy saving. When the MCU6 is in a low power consumption state, thepower supply module 1 is in zero power consumption, and the energy saving effect is good.

具体的，参照图1，本发明的实施例的一种节能遥控控制模块，具体是一种应用于汽柴油发电机组的遥控控制模块，该遥控控制模块一方面需要作为接收端接收远程的遥控指令，另一方面还需要根据遥控指令进行动作。Specifically, with reference to FIG. 1 , an energy-saving remote control module according to an embodiment of the present invention is specifically a remote control module applied to a gasoline and diesel generator set. On the one hand, the remote control module needs to be used as a receiver to receive remote remote control commands. , on the other hand, it also needs to act according to the remote control command.

该节能遥控控制模块由供电模块1供电，包括数字控制开关2、耗电模块以及其他控制模块8。The energy-saving remote control module is powered by apower supply module 1 , and includes adigital control switch 2 , a power consumption module and other control modules 8 .

所述供电模块1，用于给耗电模块供电，同时还要承担比如启动发动机，因此，这类模块通常需要较大电压的电源才能完成启动发动机组，现有技术中一般采用的是12V的电源，因此本实施例中也采用12V的电源。Thepower supply module 1 is used to supply power to the power-consuming module, and at the same time, it is also responsible for starting the engine. Therefore, this type of module usually requires a power supply with a relatively large voltage to start the engine group. In the prior art, a 12V power supply is generally used. Therefore, the 12V power supply is also used in this embodiment.

所述耗电模块，包括无线接收模块7和MCU6。所述无线接收模块7，用于接收无线控制信号并传递给MCU6。所述MCU6，其工作状态根据预设的方式在低功耗状态和正常功耗状态之间切换；所述MCU6一方面用于接收无线接收模块7传递的无线控制信号并实施相应动作，另一方面用于控制数字控制开关2在MCU6将进入低功耗状态时切断，以及在MCU6将进入正常功耗状态时导通。The power consumption module includes awireless receiving module 7 and an MCU6. Thewireless receiving module 7 is used to receive wireless control signals and transmit them to the MCU6. The working state of the MCU 6 is switched between the low power consumption state and the normal power consumption state according to a preset method; the MCU 6 is used to receive the wireless control signal transmitted by thewireless receiving module 7 on the one hand and perform corresponding actions, and on the other hand The aspect is used to control thedigital control switch 2 to be turned off when the MCU6 will enter a low power consumption state, and turned on when the MCU6 will enter a normal power consumption state.

所述数字控制开关2，设置于供电模块1与耗电模块之间，用于控制供电模块1与耗电模块之间的电路导通与否。Thedigital control switch 2 is disposed between thepower supply module 1 and the power consumption module, and is used to control whether the circuit between thepower supply module 1 and the power consumption module is connected or not.

所述其他控制模块8，主要是受控于MCU6的模块，如图1所示，根据这些控制模块的功能设定其位置，有的需要始终通电的直接与供电模块1连接，有的可以间断通电的通过数字控制开关2与供电模块1连接。这些其他控制模块8也会耗电，设置在数字控制开关2后的其他控制模块8可以与上述耗电模块同样实现节能控制。The other control modules 8 are mainly modules controlled by the MCU 6. As shown in Figure 1, their positions are set according to the functions of these control modules. Some of them need to be always powered on and directly connected to thepower supply module 1, and some can be interrupted. The powered one is connected to thepower supply module 1 through thedigital control switch 2 . These other control modules 8 also consume power, and the other control modules 8 disposed behind thedigital control switch 2 can implement energy-saving control in the same way as the above-mentioned power consumption modules.

所述数字控制开关2包括但不限于1个，如本实施例中，采用1个数字控制开关2，在其他实施例中，也可以设置多个并联形式的数字控制开关2，不同的数字控制开关2控制不同的其他控制模块8以及耗电模块。Thedigital control switch 2 includes but is not limited to one. For example, in this embodiment, onedigital control switch 2 is used. Theswitch 2 controls various other control modules 8 as well as power consumption modules.

具体的，所述MCU6于上电后进行初始化配置并处于待机模式，并在此后按照以下步骤进行工作：Specifically, the MCU6 is initialized and configured after being powered on and is in a standby mode, and then works according to the following steps:

第一步、MCU6处于正常功耗状态，检测无线接收模块7发来的无线控制信号是否为有效的特征信号，若在开通延时T1时间内未接收到有效的特征信号，则进入第二步；否则，则进入第三步。In the first step, the MCU6 is in a normal power consumption state, and detects whether the wireless control signal sent by thewireless receiving module 7 is a valid characteristic signal. If no valid characteristic signal is received within the turn-on delay time T1, the second step is entered. ; otherwise, go to the third step.

这里有效的特征信号可根据需要设定，包括但不限于指遥控数据信号‘0’和‘1’的高低电平特征脉冲宽度或正常一帧遥控数据或其中某一段。The valid characteristic signals here can be set as required, including but not limited to the high and low level characteristic pulse widths of the remote control data signals '0' and '1', or a normal frame of remote control data or a certain segment thereof.

第二步、MCU6进入低功耗状态，持续时间为关断延时T2，此后返回第一步。In the second step, the MCU6 enters a low power consumption state, and the duration is the turn-off delay T2, and then returns to the first step.

第三步、MCU6持续监听无线接收模块7发来的无线控制信号是否为有效的控制命令，若在监听延时T3时间内接收到有效的控制命令，则执行该命令以及判断是否需要退出待机模式，若需要退出待机模式则进入第四步；若在监听延时T3时间内未接收到有效的控制命令，进入第二步。In the third step, the MCU6 continues to monitor whether the wireless control signal sent by thewireless receiving module 7 is a valid control command. If a valid control command is received within the monitoring delay T3, the command is executed and it is judged whether it is necessary to exit the standby mode. , if it needs to exit the standby mode, go to the fourth step; if no valid control command is received within the monitoring delay time T3, go to the second step.

第四步、MCU6退出待机模式持续监听、解码和执行无线接收模块7发来的各项命令，直到监听到需要待机的命令并执行后，比如关机，MCU6进入待机模式，并进入第二步。In the fourth step, the MCU6 exits the standby mode and continuously monitors, decodes and executes various commands sent by thewireless receiving module 7, until it monitors and executes the commands that require standby, such as shutting down, and the MCU6 enters the standby mode and enters the second step.

上述过程中，开通延时T1期间，MCU6正常功耗，数字控制开关2导通，无线接收模块7正常工作；关断延时T2期间，MCU6低功耗，数字控制开关2断开，无线接收模块7断电不工作。为了兼顾节能和正常工作，设定所述T1:T2<1:10。In the above process, during the turn-on delay T1, the MCU6 consumes normal power, thedigital control switch 2 is turned on, and thewireless receiving module 7 works normally; during the turn-off delay T2, the MCU6 consumes low power, thedigital control switch 2 is turned off, andwireless reception Module 7 does not work when powered off. In order to take into account both energy saving and normal work, the T1:T2<1:10 is set.

由于无线接收模块7和MCU6的工作电压都只要3.3V，远低于供电模块1的12V电压，因此，需要在数字控制开关2与耗电模块之间设置降压模块3以及二极管，用于将供电模块1的电压降压后供给耗电模块。Since the working voltage of thewireless receiving module 7 and the MCU6 is only 3.3V, which is much lower than the 12V voltage of thepower supply module 1, it is necessary to set a step-downmodule 3 and a diode between thedigital control switch 2 and the power consumption module. The voltage of thepower supply module 1 is stepped down and supplied to the power consumption module.

如图1所示，二极管设置在降压模块3与耗电模块之间具体的，在降压模块3与MCU6之间设置第一二极管41，其导通方向为从降压模块3流向MCU6，在降压模块3与无线接收模块7之间设置第二二极管42，其导通方向为从降压模块3流向无线接收模块7。As shown in FIG. 1 , the diode is arranged between the step-downmodule 3 and the power consumption module. Specifically, afirst diode 41 is arranged between the step-downmodule 3 and the MCU 6 , and its conduction direction is from the step-downmodule 3 to the MCU 6 . In the MCU 6 , asecond diode 42 is arranged between the step-downmodule 3 and thewireless receiving module 7 , and the conduction direction of thediode 42 is from the step-downmodule 3 to thewireless receiving module 7 .

这里的两个二极管都具有配合降压模块3进一步降压的作用，降压模块3负责将电压从12V降低到4V，二极管负责将电压从4V降低到3.3V。特别的，第一二极管41还具有防止反流的作用，由于第一二极管41的单向导通作用，当电容5充满电后，只供给MCU6，以保证当数字控制开关断开后，电容5内存的电能可以保证MCU6尽可能长时间工作。The two diodes here both have the function of cooperating with the step-downmodule 3 to further reduce the voltage. The step-downmodule 3 is responsible for reducing the voltage from 12V to 4V, and the diode is responsible for reducing the voltage from 4V to 3.3V. In particular, thefirst diode 41 also has the function of preventing reverse current. Due to the unidirectional conduction effect of thefirst diode 41, when thecapacitor 5 is fully charged, it is only supplied to the MCU 6 to ensure that when the digital control switch is turned off , the power of thecapacitor 5 memory can ensure that the MCU6 works as long as possible.

更为细节的，在MCU6的电源引脚与电源负极之间还并联有电容5，该电容5在MCU6正常工作期间获得来自供电模块1的供电使得电容5内存储一定的电量，在MCU6进入低功耗状态时，电容5中存储的电量用于对MCU6供电以维持其低功耗状态直到其切换到正常功耗状态，此后开通数字控制开关2以给整个遥控控制系统供电和给其电源引脚并联的电容5补充电能。In more detail, acapacitor 5 is connected in parallel between the power supply pin of MCU6 and the negative pole of the power supply. Thecapacitor 5 obtains power supply from thepower supply module 1 during the normal operation of MCU6, so that a certain amount of power is stored in thecapacitor 5. In the power consumption state, the power stored in thecapacitor 5 is used to supply power to the MCU6 to maintain its low power consumption state until it switches to the normal power consumption state, after which thedigital control switch 2 is turned on to supply power to the entire remote control system and to supply its power supply. Thecapacitor 5 connected in parallel with the foot supplements the electric energy.

作为更优的实施例，所述数字控制开关2上还设置有上电触发电路11，用于在整个模块上电瞬间产生脉冲信号以触发数字控制开关2导通，以激活整个系统开始工作。上电触发电路11具体是由电阻、电容5等无源器件构成，该技术为本领域内的现有技术，具体方案可由技术人员自由设计，在此不做赘述。As a more preferred embodiment, thedigital control switch 2 is also provided with a power-ontrigger circuit 11 for generating a pulse signal at the moment of power-on of the entire module to trigger thedigital control switch 2 to be turned on to activate the entire system to start working. The power-ontrigger circuit 11 is specifically composed of passive devices such as resistors andcapacitors 5 . This technology is the prior art in the field, and the specific scheme can be freely designed by the skilled person, and will not be repeated here.

需要特别指出的，在MCU6处于低功耗状态下，上电触发电路仍会有一个很小的漏电流，因此会少量消耗供电模块1电量，但由于电流微弱，其影响可以忽略不计。It should be specially pointed out that when the MCU6 is in a low power consumption state, the power-on trigger circuit will still have a small leakage current, so it will consume a small amount of power of thepower supply module 1, but due to the weak current, its influence can be ignored.

进一步的，在本案中还包括一机械开关10，所述机械开关10设置于供电模块1与数字控制开关2之间。机械开关10用于给操作人员操作，必要时通过机械开关10实现完全断电。Further, in this case, amechanical switch 10 is also included, and themechanical switch 10 is arranged between thepower supply module 1 and thedigital control switch 2 . Themechanical switch 10 is used for the operator to operate, and if necessary, a complete power-off is achieved through themechanical switch 10 .

如图2所示，利用上述节能遥控控制模块进行节能控制，在数字控制开关2导通后，开始检测无线接收模块7的输出，当检测到无线控制命令后，根据控制命令控制系统其他控制单元。As shown in Fig. 2, the energy-saving control is performed by using the above-mentioned energy-saving remote control control module. After thedigital control switch 2 is turned on, the output of thewireless receiving module 7 starts to be detected. When the wireless control command is detected, other control units of the system are controlled according to the control command. .

具体的，在上电瞬间，上电触发模块产生一个脉冲信号控制数字控制开关2导通，MCU6得电后，先后完成设置IO口，控制开通数字控制开关2、配置定时器、设置待机标志位FD为1、设置待机状态数字控制开关2的开通延时T1、设置待机状态数字控制开关2的关断延时T2、设置待机状态控制命令监听延时T3和清零计时器等系统参数初始化工作。Specifically, at the moment of power-on, the power-on trigger module generates a pulse signal to control thedigital control switch 2 to be turned on. After the MCU6 is powered on, it successively sets the IO port, controls the opening of thedigital control switch 2, configures the timer, and sets the standby flag bit. FD is 1, set the turn-on delay T1 of thedigital control switch 2 in the standby state, set the turn-off delay T2 of thedigital control switch 2 in the standby state, set the control command monitoring delay T3 in the standby state, and reset the timer and other system parameters initialization work .

完成系统初始化配置后，After completing the system initialization configuration,

第1步：MCU6开始检测无线接收模块7输出‘0’或‘1’特征信号；当计时器计数值大于等于T1，而一直没有检测到有效的无线特征信号，Step 1: MCU6 starts to detect thewireless receiving module 7 to output '0' or '1' characteristic signal; when the timer count value is greater than or equal to T1, and no valid wireless characteristic signal has been detected,

第2步：MCU6执行清零计时器，开启延时唤醒功能，关断数字控制开关2，进入低功耗模式；当计时器数值大于等于T2，Step 2: MCU6 executes the reset timer, turns on the delayed wake-up function, turns off thedigital control switch 2, and enters the low power consumption mode; when the timer value is greater than or equal to T2,

第3步：MCU6自动唤醒，清零计时器并重复执行和第1-3步。Step 3: MCU6 wakes up automatically, clears the timer and repeats steps 1-3.

当MCU6接收到‘0’或‘1’无线特征信号后，When the MCU6 receives the '0' or '1' wireless feature signal,

第4步：清零计时器并持续监听解码无线接收模块7输出；Step 4: Clear the timer and continue to monitor and decode the output of thewireless receiving module 7;

当计时器数值大于等于T3，MCU6没有监听到有效的控制命令，则进入第2步；When the timer value is greater than or equal to T3, and the MCU6 does not monitor a valid control command, it goes to step 2;

当监听到有效的控制命令，则执行该命令后根据具体命令判断是否需要退出待机模式，如果是启动机器之类的命令，则进入When listening to a valid control command, after executing the command, judge whether it is necessary to exit the standby mode according to the specific command. If it is a command such as starting the machine, enter the

第7步：整过系统退出待机模式(FD＝0)并持续监听、解码并执行无线接收模块7输出的各项命令。当监听到关机等需要后续待机等一类命令后，执行完关机命令后，整个控制系统进入Step 7: After the whole system exits the standby mode (FD=0) and continues to monitor, decode and execute the commands output by thewireless receiving module 7 . After listening to commands such as shutdown and other commands that require subsequent standby, after executing the shutdown command, the entire control system enters the

第8步：恢复待机模式(FD＝1)并执行第2步。Step 8: Return to standby mode (FD=1) and performstep 2.
