Scheduling With Short Term Security Constrained Unit Commitment

本系统以stm32f103单片机为核心，充分利用单片机丰富的内部和外部资源及数字温度传感器DS18B20的优越性能，结合LCD显示屏、降温风扇，实现对温度的多点测量、显示与控制。(This system takes STM32F103 as the core, makes full use of the abundant internal and external resources of the single chip microcomputer and the superiority of digital temperature sensor DS18B20, combines the LCD display screen and cooling fan to realize the multi-point measurement, display and control of temperature.)

该工具可以根据输入的UNICODE十六进制字符串计算出相应的汉字或ASCII码。比如：输入4F60便可以得到"你"。(The tool can be based on the input UNICODE calculate the corresponding hexadecimal string guy or ASCII.)

这是avr单片机键盘实验的程序很好很实用在此先给大家，非常全面的(Avr microcontroller is a good keyboard is very useful experimental procedure we give in this very comprehensive)

Beginning Visual C_ 2012 Programming

AD5420操作代码，可以方便的对5420进行读写，5420为SPI通讯，且一般用于工业控制。(AD5420 operation code, you can easily read and write to the 5420, 5420 as SPI communications, and is generally used for industrial control.)

说明：  如果要将此应用项目移植到开发板上，只需要根据此项目的电路图修改管脚，改成我们开发板对应的管脚上。温湿度传感器使用的是DHT11，所以数据口按照原理图内接。温度传感器接口也需要修改成我们开发板对应的接口(If you want to transplant this application project to the development board, you only need to modify the pins according to the circuit diagram of this project and change it to the corresponding pin of our development board. The temperature and humidity sensor uses DHT11, so the data port is internally connected according to the schematic diagram. The temperature sensor interface also needs to be modified to the corresponding interface of our development board)

汽车安全与防盗最初的电子化开始于1994年的引擎防盗(IMMO)，恩智浦半 导体(当时的飞利浦半导体)作为第一家半导体公司把RFID的电子标签技术成功 的应用于汽车电子引擎锁：通过汽车与钥匙间的125kHz的无线通讯实现电子身 份识别，来判断启动汽车引擎。这一技术极大的提高了汽车的安全性，很快就在 欧洲以及北美地区广泛应用，并在短短几年时间内使欧洲的汽车失窃率大幅降低 了90 ，因而成为整个欧洲的汽车标准配置(Automotive safety and anti-theft electronic originally began in 1994, engine anti-theft (IMMO), NXP (then Philips Semiconductors) as the first semiconductor company to RFID electronic tag technology successfully used in automotive electronic engine lock: By car keys between 125kHz and wireless communications for electronic identification, to determine start the car engine. This technology greatly improves the car' s safety, soon in Europe and North America, widely used, and in a few years time so that European auto theft rate significantly reduced by 90 , and thus the entire European automotive Standard configuration)
