小学思维数学讲义：最值中的数字谜（一）-带详解最值中的数字谜（一）1. 掌握最值中的数字谜的技巧2. 能够综合运用数论相关知识解决数字谜问题数字谜中的最值问题常用分析方法1. 数字谜一般分为横式数字谜和竖式数字谜．横式数字谜经常和数论里面的知识结合考察，有些时候也可以转化为竖式数字谜；2. 竖式数字谜通常有如下突破口：末位和首位、进位和借位、个位数字、位数的差别等．3. 数字谜的常用分析方法有：个位数字分析法、高位数字分析法、数字大小估算分析法、进位错位分析法、分解质因数法、奇偶分析法等．4. 除了数字谜问题常用的分析方法外，还会经常采用比较法，通过比较算式计算过程的各步骤，得到所求的最值的可能值，再验证能否取到这个最值．5. 数字谜问题往往综合了数字的整除特征、质数与合数、分解质因数、个位数字、余数、分数与小数互化、方程、估算、找规律等题型。

【例1】有四个不同的数字，用它们组成最大的四位数和最小的四位数，这两个四位数之和是11469，那么其中最小的四位数是多少？【考点】加减法的进位与借位【难度】3星【题型】填空【解析】设这四个数字是a b c d >>>，如果0d ≠，用它们组成的最大数与最小数的和式是11469a b c dd c b a +，由个位知9a d +=，由于百位最多向千位进1，所以此时千位的和最多为10，与题意不符．所以0d =，最大数与最小数的和式为0011469a b c c b a +，由此可得9a =，百位没有向千位进位，所以11a c +=，2c =；64b c =-=．所以最小的四位数cdba 是2049．【答案】2049【例2】将一个四位数的数字顺序颠倒过来，得到一个新的四位数，如果新数比原数大7902，那么所有符合这样条件的四位数中原数最大的是．7902D C B AA B C D -例题精讲知识点拨教学目标【考点】加减法的进位与借位【难度】4星【题型】填空【解析】用A 、B 、C 、D 分别表示原数的千位、百位、十位、个位数字，按题意列减法算式如上式．从首位来看A 只能是1或2，D 是8或9；从末位来看，102A D +-=，得8D A =+，所以只能是1A =，9D =．被减数的十位数B ，要被个位借去1，就有1B C -=．B 最大能取9，此时C 为8，因此，符合条件的原数中，最大的是1989．【答案】1989【例 3】在下面的算式中，A 、B 、C 、D 、E 、F 、G 分别代表1～9中的数字，不同的字母代表不同的数字，恰使得加法算式成立．则三位数EFG 的最大可能值是．2006A B C DE F G +【考点】加减法的进位与借位【难度】4星【题型】填空【解析】可以看出，1A =，6D G +=或16．若6D G +=，则D 、G 分别为2和4，此时10C F +=，只能是C 、F 分别为3或7，此时9B E +=，B 、E 只能分别取()1,8、()2,7、()3,6、()4,5，但此时1、2、3、4均已取过，不能再取，所以D G +不能为6，16D G +=．这时D 、G 分别为9和7；且9C F +=，9B E +=，所以它们可以取()3,6、()4,5两组．要使EFG 最大，百位、十位、个位都要尽可能大，因此EFG 的最大可能值为659．事实上134********+=，所以EFG 最大为659．【答案】659【巩固】如图，相同的汉字代表相同的数字，不同的汉字代表不同的数字，那么四位数“奥林匹克”最大是奥林匹克+奥数网2008【考点】加减法的进位与借位【难度】4星【题型】填空【关键词】学而思杯，6年级，1试，第2题【解析】显然“2≤奥”，所以“1=奥或2”，如果“2=奥”，则四位数与三位数的和超过2200，显然不符合条件，所以“1=奥”，所以“9≤林”，如果“9=林”那么“200819001008+=--=匹克数网”，“0=匹=数”，不符合条件，所以“林”最大只能是8，所以“20081800100108+=--=匹克数网”，为了保证不同的汉字代表不同的数字，“匹克”最大是76，所以“奥林匹克”最大是1876。

Please reduce thenumber of light beads appropriatelywhen the power exceeds the limit.Taking SpeedyBee Programable2812 Arm LED strips as an example,a total of 17 LED strips can beinstalled, including approximately68 light beads.LED strip connectorUART6 jumperSH1.0 3PSH1.0 3PSH1.0 3PWiring DiagramUSB extenderSR ST4S2S1VX VX4V5G G GGGGGGGVXVXVXVXVXVXS3S4S5S6S7S8SR14V5GND5VT4R4G8I428P7AA12203T E L EM2/4Wireless boardFC boardPDB boardPower supplyThe power distribution logic for the F405 WING APP is as follows:1、 The 9V pad uses a VTX&CAM BEC for power supply. When the VTX&CAM BEC switches to another voltage through the pad jumper, the 9V pad will output the corresponding voltage.2、The Vx pin headers use a Servo BEC for power supply. When the Servo BEC switches to anothervoltage through the pad jumper, the Vx pin headers will output the corresponding voltage.3、The default voltage for the FC BEC is 5.2V, with power output divided into three directions:·The first path directly outputs to the 5V pad.·The second path outputs to the onboard chip and 4V5 pad through a diode.·The third path outputs to the LED connector through a self-recovering fuse and reverse connection protection circuit.The limit for the LED connector power supply is approximately 68 pieces of SpeedyBee 5050 LED strip beads. Do not exceed this limit.To test if other brands of LED strips meet the power requirements, you can take the following steps:·After connecting the LED strip, let the flight controller be powered and idle for 10 minutes. Observe if the color of the LED strip suddenly dims and feel the wireless board with your hand. If it feels very hot, the power supply is insufficient, and you need to reduce the number of LED beads.·You can also use a multimeter to test the voltage of the 5V pad or the LED strip power pad. If thevoltage is below 5V, it indicates that the power supply is insufficient, and you need to reduce thenumber of LED beads.Note: If your ESC supports BEC output, do not connect the ESC BEC red wire to the Vx pinheaders, as this may burn the ESC or Servo BEC.Please note that the FC BEC can provide a continuous current of 2.4-2.5A and a peak current of 3A. The onboard chip requires less than 1A of power, GPS and receivers generally require less than 0.1A, and the wireless controller requires 0.1A.If the LED connector uses a maximum of 1.3A, the 5V pad will have no remaining capacity.If the LED connector is not used, the 5V pad will have a 1.3A surplus.APP connectionPart3-Firmware upgrade andAPP connection①Press and hold the BOOT button , andconnect the FC to the computer viaUSB cable.②Open the INAV Configurator on yourcomputer, go to the "Firmware Flasher "page, select the flight controller targetas "SPEEDYBEEF405WING", and thenflash the firmware.③To flash Ardupilot firmware, follow thesame steps as above, select "LoadFirmware [local]", and then flashthe firmware.SpeedyBee F405 WING APP not supportingwireless firmware flashing, please update thefirmware on a computer.

习题P2185.1图1所示为伺服控制系统组成原理图，它包括控制器、伺服驱动器、伺服电机和位置检测反馈元件。

伺服驱动器通过执行控制器的指令来控制伺服电机，进而驱动机械装备的运动部件（这里指的是丝杠工作台），实现对装备的速度、转矩和位置控制。

图1 伺服控制系统组成原理图从自动控制理论的角度来分析，伺服控制系统一般包括控制器、被控对象、执行环节、检测环节、比较环节等五部分。

（1）比较环节比较环节是将输入的指令信号与系统的反馈信号进行比较，以获得输出与输入间的偏差信号的环节，通常由专门的电路或计算机来实现。

（2）控制器控制器通常是PLC、计算机或PID控制电路，其主要任务是对比较元件输出的偏差信号进行变换处理，以控制执行元件按要求动作。

（3）执行环节执行环节的作用是按控制信号的要求，将输入的各种形式的能量转化成机械能，驱动被控对象工作，这里一般指各种电机、液压、气动伺服机构等。

（4）被控对象机械参数量包括位移、速度、加速度、力、力矩为被控对象。

（5）检测环节检测环节是指能够对输出进行测量并转换成比较环节所需要的量纲的装置，一般包括传感器和转换电路。

5.2交流伺服驱动器中一般都包含有位置回路、速度回路和转矩回路，但使用时可将驱动器、电机和运动控制器结合起来组合成不同的工作模式，以满足不同的应用要求。

伺服驱动器主要有速度控制、转矩控制和位置控制等三种模式。

（1）速度控制模式图2所示的伺服驱动器的速度控制采取跟变频调速一致的方式进行，即通过控制输出电源的频率来对电动机进行调速。

此时，伺服电机工作在速度控制闭环，编码器会将速度信号检测反馈到伺服驱动器，跟设定信号（如多段速、电位器设定等）进行比较，然后进行速度PID控制。

图2 速度控制模式（2）转矩控制模式图3所示的伺服驱动器转矩控制模式是通过外部模拟量输入来控制伺服电机的输出转矩。

图3 转矩控制模式（3）位置控制模式图4所示的驱动器位置控制模式可以接受PLC或定位模块等运动控制器送来的位置指令信号。

1.启动控制SDH7611SH集成了高压启动供电电路，无需启动电阻和辅助绕组供电。

芯片通过HV端直接从高压端口取电，给内部电源VCC供电，极大的简化了外围电路，同时也减小了系统启动时间。

系统上电后，芯片通过HV端、经过高压启动电路给VCC和VDD充电，当VDD电压达到芯片开启阈值时，芯片开始工作；特色的电路设计，也使得芯片无需外部电源电容就能稳定工作。

2.恒流控制LED输出电流计算公式为：I LED=V CS4∗R CS∗N PN S其中Np是变压器原边匝数；Ns是副边匝数。

Vcs为内部基准电压，0.6V。

Rcs为电流采样电阻。

3.保护功能SDH7611SH内置完善的保护功能，包括LED开路保护，欠压保护、过热调节等。
