基于STM32的餐车机器人

基于STM32的餐车机器人

• 13•如今,人工智能成为新一轮技术革命和工业变化的核心力量,推动了传统工业的更新换代,各行各业均在积极向智能技术转变,服务行业也是如此。

传统点菜是依靠纯人工方式进行,造成了点餐效率低,服务体验质量差等问题。

因此,在智能化不断普及的背景下,服务行业进入智能服务机器人时代已经是大势所趋。

由于我国铁路的迅速发展,且具有方便、快捷、实惠等特点,使得铁路成为不少人出行的第一选择。

但是传统的铁路运输送餐模式选用人工推车式送餐,这种送餐模式效率低下,不仅不能实现随时点餐的需求而且容易因餐车体积庞大占据车厢过道而造成拥堵问题。

本文设计的餐车机器人将专门应用于铁路运输,其最大特点是缩小了传统餐车的体积,且操作灵活、运输平稳,能从根本上解决车厢拥堵问题,提高了旅客的乘车满意度。

同时,本产品的设计,实现了“随想随点、随点随做、随做随送”的一系列人性化服务,运用智能化服务模式取代人工服务模式,可以大大降低人为缘故的出错概率,有效提高服务质量和效率,更能满足旅客的用餐需求。

1 整体设计结构餐车机器人以STM32F103ZET6作为主控芯片,主要功能有:循迹、避障、显示点餐信息、点评服务以及人机对话。

餐车的循迹功能是通过灰度模块实现,使用超声波模块检测障碍物达到避障效果,利用车内的液晶屏显示用户点餐信息,采用按键输入模块对服务进行评价,添加语音模块实现人机对话,进一步提高人机交互感。

Cortex-M3,最高工作频率为72MHz 。

同时作为STM32F1系列中最高配置的芯片,其拥有:64KB SRAM 、 512KB FLASH 、4个通用定时器、2个基本定时器、2个高级定时器、2个DMA 控制器、2个IIC 、5个串口、1个USB 、3个12 位ADC 以及112个通用IO 口等。

出于项目代码量与需要运行UC/OS-II 操作系统综合考虑后,我们决定选用大容量Flash 的ZET6类型设计本产品,运用到的芯片外设有颜色传感器的ADC 转换,两路特殊的高级定时器产生PWM 控制电机等。

硬盘内部硬件结构和工作原理详解概论

硬盘内部硬件结构和工作原理详解概论

图1-1 硬盘的外观图1-2 控制电路板图1-3 硬盘接口电源插座连接电源,为硬盘工作提供电力保证。

数据接口是硬盘与主板、内存之间进行数据交换的通道,使用一根40针40线(早期)或40针80线(当前)的IDE 接口电缆进行连接。

新增加的40线是信号屏蔽线,用于屏蔽高速高频数据传输过程中的串扰。

中间的主、从盘跳线插座,用以设置主、从硬盘,即设置硬盘驱动器的访问顺序。

其设置方法一般标注在盘体外的标签上,也有一些标注在接口处,早期的硬盘还可能印在电路板上。

此外,在硬盘表面有一个透气孔(见图1-1),它的作用是使硬盘内部气压与外部大气压保持一致。

由于盘体是密封的,所以,这个透气孔不直接和内部相通,而是经由一个高效过滤器和盘体相通,用以保证盘体内部的洁净无尘,使用中注意不要将它盖住。

1.2 硬盘的内部结构硬盘的内部结构通常专指盘体的内部结构。

盘体是一个密封的腔体,里面密封着磁头、盘片(磁片、碟片)等部件,如图1-4所示。

图1-4 硬盘内部结构硬盘的盘片是硬质磁性合金盘片,片厚一般在0.5mm左右,直径主要有1.8in(1in=25.4mm)、2.5in、3.5in和5.25in 4种,其中2.5in和3.5in盘片应用最广。

盘片的转速与盘片大小有关,考虑到惯性及盘片的稳定性,盘片越大转速越低。

一般来讲,2.5in硬盘的转速在5 400 r/min~7 200 r/ min之间;3.5in硬盘的转速在4 500 r/min~5 400 r/min之间;而5.25in硬盘转速则在3 600 r/min~4 500 r/min之间。

随着技术的进步,现在2.5in硬盘的转速最高已达15 000 r/min,3.5in硬盘的转速最高已达12 000 r/min。

有的硬盘只装一张盘片,有的硬盘则有多张盘片。

这些盘片安装在主轴电机的转轴上,在主轴电机的带动下高速旋转。

每张盘片的容量称为单碟容量,而硬盘的容量就是所有盘片容量的总和。

ssd固态硬盘的原理深层透视

SSD固态硬盘的原理深层透视2012-08-07 10:23:18 来源: 作者: 【大中小】浏览:501次评论:0条目前市场是流通的SSD固态硬盘的工作原理都是大家很好奇的,这里就对SSD的工作原理进行讲解,让大家能更好的进行购买和使用。

SSD固态硬盘的接口规范和定义、功能及使用方法上与普通硬盘的相同,在产品外形和尺寸上也与普通硬盘一致。

由于固态硬盘没有普通硬盘的旋转介质,因而抗震性极佳。

其芯片的工作温度范围很宽(-40~85摄氏度)。

SSD固态硬盘工作原理下面是一个关于NAND闪盘的原理图。

从下图我们可以看到,每一个“单元”就是由一个这样的晶体管组成的。

在单级单元(SLC,single level cell)闪存设备中,一个晶体管可容纳1比特数据。

您通过电子通道将数据写入单元;将足够高的电压加于两端,创造一个足够强大的电场,电子将穿透氧化物进入浮动门。

消除电压,电子将继续停留在浮动门。

将电压穿越通道而不施加到门上,扭转偏压,电子将向另一个方向移动。

简单的说,这就是闪盘的工作原理-你有两种状态,0和1,即使单元没有电了,状态也会维持住,因此对存储设备来说是非常理想的。

编程闪存是一个反复的过程。

该控制器将电压施于门(或通道)上,允许一些电子穿过并检查单元的临界电压。

当临界电压已达到一些预定的值时,就开始编程并储存数据了。

MLC与SLC的区别目前SSD固态硬盘硬盘使用两种形式的NAND闪存:单级单元(SLC)和多级单元(MLC)。

两者之间的差别是每单元存储的数据量,SLC每单元存储1比特而MLC每单元存储2比特。

关键在于,SLC和MLC占据了相同大小的芯片面积。

因此,在同样的价格下,MLC可以有两倍容量的效果。

英特尔的SLC和MLC闪存实际上使用了相同的晶体管,不同之处在于怎样读/写这两个闪存。

SLC只有两个电压符,因为它只有两个状态(0或1)。

MLC却有四个状态(00,01,10 ,11),因此需要花费较长的时间来访问,因为你不想意外写入错误的数据;您已有了相同的最大、最小电压,您现在仅仅有它们两者之间更多的刻度:SLC (left) vs. MLC (right)SLC和MLC的擦除性能是一样的,MLC闪存的读取性能需花费两倍长的时间,写入性能需花费四倍长的时间。

When 6800-series Parallel Interface is selected, this pin is used as Enable (E) signal. Read/Write operation is initiated when this pin is pulled HIGH and the CS# pin is pulled LOW. When 8080-series Parallel Interface is selected, this pin is used to receive the Read Data (RD#) signal. Data read operation is initiated when this pin is pulled LOW and CS# pin is pulled LOW.D 7-D 0These are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. When serial interface mode is selected, D 1 will be the serial data input, SDIN, D 0 will be the serial clock input, SCLK, and D 2 should be left opened.VDDThis is a voltage supply pin. It must be connected to external source.VSSThis is a ground pin. It also acts as a reference for the logic pins and the OLED driving voltages. It must be connected to external ground.BGGNDThis is a ground pin for analog circuits. It must be connected to external groundVCCThis is the most positive voltage supply pin of the chip. It should be supplied externally.VREFThis is a voltage reference pin for pre-charge voltage in driving OLED device.

The oscillator generates the clockfor the Display Timing Generator.7.2 Reset CircuitWhen RES# pin is pulled LOW, the chip is initialized with the following status:1. Display is OFF2. 132 x 64 Display Mode3. Normal segment and display data column address and row address mapping (SEG0 is mapped tocolumn address 00H and COM0 is mapped to row address 00H)4. Shift register data clear in serial interface5. Display start line is set at display RAM address 06. Column address counter is set at 07. Normal scan direction of the COM outputs8. Contrast control register is set at 80H9. DC/DC enable7.3 Command Decoder and Command InterfaceThis module determines whether the input data is interpreted as data or command. When the D/C# pin is pulled HIGH, the inputs at D7-D0 are interpreted as data and be written to Graphic Display Data RAM (GDDRAM). When it is pulled LOW, the inputs at D7-D0 are interpreted as command, they will be decoded and be written to the corresponding command registers.7.4 MPU Parallel 6800-series InterfaceThe parallel interface consists of 8 bi-directional data pins (D7-D0), R/W (WR#), E (RD#), D/C, CS#. When the R/W (WR#) pin is pulled HIGH, Read operation from the Graphic Display Data RAM (GDDRAM) or the status register occurs. When the R/W (WR#) pin is pulled LOW, Write operation to Display Data RAM or Internal Command Registers occurs, depending on the status of D/C input. The E (RD#) input serves as data latch signal (clock) when HIGH provided that CS# is LOW. Refer to Parallel Interface Timing Diagram of 6800-series microprocessors.In order to match the operating frequency of display RAM with that of the microprocessor, some pipeline processing is internally performed, which requires the insertion of a dummy read before the first actual display data read. This is shown in Figure 5 below.Figure 5 - Display data read back procedure - insertion of dummy read7.5 MPU Parallel 8080-series InterfaceThe parallel interface consists of 8 bi-directional data pins (D7-D0), R/W (WR#), E (RD#), D/C, CS#. The E (RD#) input serves as data read latch signal (clock) when it is LOW provided that CS# is LOW. Display data or status register read is controlled by D/C signal.R/W (WR#) input serves as data write latch signal (clock) when it is HIGH and provided that CS# is LOW. Display data or command register write is controlled by D/C. Refer to Parallel Interface Timing Diagram of 8080-series microprocessor. Similar to 6800-series interface, a dummy read is also required before the first actual display data read.7.6 MPU Serial InterfaceThe serial interface consists of serial clock SCLK, serial data SDIN, D/C#, CS#. In SPI mode, D0 acts as SCLK, D1 acts as SDIN. For the unused data pins, D2 should be left open. D3 to D7, E and R/W pins can be connected to external ground.SDIN is shifted into an 8-bit shift register on every rising edge of SCLK in the order of D 7, D 6, ... D 0. D/C# is sampled on every eighth clock and the data byte in the shift register is written to the Display Data RAM or command register in the same clock.During data writing, an additional NOP command should be inserted before the CS# goes high (Refer to Figure 6.Figure 6 – Display data write procedure in SPI modeSCLK(D0)SDIN(D1)CS#D/CSDIN/SCLK7.7 Graphic Display Data RAM (GDDRAM)The GDDRAM is a bit mapped static RAM holding the bit pattern to be displayed. The size of the RAM is 132 x 64 bits. For mechanical flexibility, re-mapping on both Segment and Common outputs can be selected by software.For vertical scrolling of the display, an internal register storing display start line can be set to control the portion of the RAM data to be mapped to the display.7.8 Current Control and Voltage ControlThis block is used to derive the incoming power sources into different levels of internal use voltage and current. VCC and VDD are external power supplies. VREF is reference voltage, which is used to derive the driving voltage for segments and commons. IREF is a reference current source for segment current drivers.7.9 Segment Drivers / Common DriversSegment drivers deliver 132 current sources to drive OLED panel. The driving current can be adjusted from 0 to 300uA with 256 steps. Common drivers generate voltage scanning pulses.7.10 Area Colour DecoderPage 0 and Page 1 of the display are divided into 32 banks. Bank16 and Bank32 comprise of a display area of 12 x 8 pixels. Other banks (0~15 & 17~31) have matrices of 8 x 8 pixels. Each bank can be programmed to any one of the four colours (colour A, B, C, D). Detailed operation can be referred to the Command Table.7.11 D C-DC Voltage ConverterIt is a switching voltage generator circuit, designed for handheld applications. In SSD1303, internal DC-DC voltage converter accompanying with an external application circuit (shown in below figure) can generate a high voltage supply V CC from a low voltage supply input V DD. V CC is the voltage supply to the OLED driver block. Below application circuit is an example for the input voltage of 3V VDD to generate V CC of 12V @0mA ~ 20mA application.Figure 7 - DC-DC voltage converter circuitL1Remark:1. VSSB is tied to VSS on SSD1303T3 package.2. L1, D1, Q1, C5 should be grouped closed together on PCB layout.3. R1, R2, C1, C4 should be grouped closed together on PCB layout.4. The VCC output voltage level can be adjusted by R1and R2, the reference formula is:VCC = 1.2 x (R1+R2) / R2The value of (R1+R2) should be between 500k to 1M Ohm.Table 3 - Passive component selection:Components Typical Value Remark10µH 1AL1 Inductor,D1 Schottky diode 1A, 25V e.g. 1N5822, BAT54 [PhilipsSemiconductors]Q1 MOSFET N-FET with low R DS(on) and low Vth voltage.e.g. MGSF1N02LT1 [ON SEMI]R1, R2 Resistor 1%,1/10WR3 Resistor, 1.2Ω1%, 1/2W1µF 16VC1 Capacitor,C2 Capacitor, 6.8µF Low ESR, 25V1µF 16VC3 Capacitor,16V10nFC4 Capacitor,C5 Capacitor, 1 ~ 10 µF 16VC6 Capacitor, 0.1 ~ 1µF 16V16V15nFC7 Capacitor,8 COMMAND TABLETable 4 - Command table(D/C =0, R/W (WR#)=0, E (RD#)=1)Note: commands marked with “**” are compatible to SSD1301D/C Hex D7 D6 D5 D4 D3 D2 D1 D0Command Description0 0 0 0 0 X 3 X 2 X 1 X 000~0FSet Lower ColumnAddress **Set the lower nibble of the column address register using X 3X 2X 1X 0 as data bits.

ssd 固态硬盘 结构原理

ssd 固态硬盘结构原理Solid state drives (SSDs) are a type of storage device that uses flash memory to store data. They are considered to be faster, more reliable, and more energy-efficient than traditional hard disk drives (HDDs). 固态硬盘(SSD)是一种使用闪存存储数据的存储设备。

相对传统硬盘驱动器(HDD)来说,SSD具有更快、更可靠和更节能的特点。

The structure of an SSD consists of controller, NAND flash memory, and a cache. The controller is the brain of the SSD, responsible for managing data storage and retrieval. NAND flash memory is where the data is actually stored, and the cache is used to temporarily store frequently accessed data for faster retrieval. 固态硬盘的结构由控制器、NAND闪存以及缓存组成。

控制器是SSD的大脑,负责管理数据存储和检索。

NAND闪存是实际存储数据的地方,而缓存用于临时存储频繁访问的数据,以加快检索速度。

One of the key advantages of SSDs is their speed. Because they have no moving parts, SSDs are able to access and retrieve data much faster than HDDs. This makes them ideal for tasks that require quick access to large amounts of data, such as gaming, video editing, andrunning multiple applications simultaneously. 固态硬盘的一个主要优势是速度。

由于CLK引脚和振荡器的输出连接到锁相环的“或”门,未使用的时钟必须接VSS。 PLL由”set_pl”命令OxE0的位1配置为系统时钟,在配置前,系统时钟为参考时钟。这使用户可以发送
“set_pll_mn”命令0xe2配置锁相环频率。当配置好锁相环频率和启用的锁相环由 “set_pll”命令0xE0的0位,用 户仍要等待100ms,待锁相环锁定。然后,锁相环准备好了,可以通过“set_pll”命令0xE0的位1,配置为系统时 钟。

广西广播电视技术中心钦州分中心摘要:在广播电视发射台站的工作中保障安全播出是重中之重,当广播电视发射机发生掉功率故障时能在规定时间段内尽快恢复正常播出是保障安全播出的重要措施。

本文为实现广播电视发射机掉功率计时而设计的一款基于嵌入式技术的计时器。

掉功率计时器由基于AD8318的功率采集监测、基于STM32的计时功能实现、7寸LCD电容触摸屏、SD卡记录储存四部分组成,实现了一种具有实际应用价值的广电嵌入式应用。

关键词:广播电视发射机,功率监测,计时器,STM32嵌入式,电容触摸屏,SD卡储存0 概述本文将从基于AD8318的功率采集监测硬件设计、基于STM32的计时功能实现、基于7寸TFT LCD电容触摸屏的计时显示及触摸操控设计、基于SD卡应用的记录存储、计时器系统软件设计等几部分来详细介绍该发射机掉功率计时器。

系统的主控芯片采用32位的STM32F103ZET6,该处理器具有较强的运算能力,具有丰富的硬件外设,例如串口、SPI接口、IIC接口、ADC接口、SDIO接口、FSMC接口等以及实时时钟RTC、高精度通用定时器等内部功能,满足本次设计要求。

本设计的系统框图如图1所示。

图2:功率检测模块原理图本计时器具有时间表设置功能,使用STM32内部的RTC功能实现RTC时钟功能,使得系统具备时间表设置功能,根据每套广播电视节目的播出时间设置时间表,确保发射机在开机时段内掉功率计时器能够实时监测发射机的功率状态。

当计时器监测到发射机发生掉功率故障时会触发声光告警,方便台站值班人员能快速发现故障,及时处理问题,保障安全播出。
