C語言是在70年代初問世的。一九七八年由美國電話電報公司(AT&T)貝爾實(shí)驗室正式發(fā)表了C語言。同時由B.W.Kernighan和D.M.Ritchit合著了著名的“THE C PROGRAMMING LANGUAGE”一書。通常簡稱為《K&R》,也有人稱之為《K&R》標(biāo)準(zhǔn)。但是,在《K&R》中并沒有定義一個完整的標(biāo)準(zhǔn)C語言,后來由美國國家標(biāo)準(zhǔn)學(xué)會在此基礎(chǔ)上制定了一個C 語言標(biāo)準(zhǔn),于一九八三年發(fā)表。通常稱之為ANSI C。

隨著光伏發(fā)電系統(tǒng)快速發(fā)展,以及電動汽車充電樁的普及,傳統(tǒng)的剩余電流保護(hù)器無法滿足實(shí)際需求。介紹了一款B型剩余電流保護(hù)器,采用磁調(diào)制剩余電流互感器和零序電流互感器采集剩余電流。根據(jù)GB/T 22794—2017標(biāo)準(zhǔn)要求,可識別1 kHz及以下的正弦交流、帶和不帶直流分量的脈動直流、平滑直流等剩余電流信號。經(jīng)信號調(diào)理電路將電壓信號送到單片機(jī)進(jìn)行采集和判斷。通過試驗測試,該樣機(jī)在測試精度和速度上均符合國家標(biāo)準(zhǔn)的相關(guān)要求。The rapid development of photovoltaic power generation systems and the popularity of electric vehicle charging piles make the traditional residual current protective devices unable to meet the actual demand.This paper proposed a type B residual current protective device,which uses the magnetically modulated residual current transformer and the zero sequence current transformer to acquire the residual current.According to the requirements of GB/T 22794—2017,the type B residual current protective device can detect sinusoidal AC residual current of 1kHz and below 1kHz,pulsating DC residual current with and without DC component,smooth DC residual current and so on.The signal processing circuit sends the voltage signal to the MCU for acquisition and judgment.Through experimental tests,the device meets the relevant requirements of national standards in terms of test accuracy and speed.

針對目前使用的RS232接口數(shù)字化B超鍵盤存在PC主機(jī)啟動時不能設(shè)置BIOS,提出一種PS2鍵盤的設(shè)計方法。基于W78E052D單片機(jī),采用8通道串行A/D轉(zhuǎn)換器設(shè)計了8個TGC電位器信息采集電路,電位器位置信息以鍵盤掃描碼序列形式發(fā)送,正交編碼器信號通過XC9536XL轉(zhuǎn)換為單片機(jī)可接收的中斷信號,軟件接收到中斷信息后等效處理成按鍵。結(jié)果表明,在滿足開機(jī)可設(shè)置BIOS同時,又可實(shí)現(xiàn)超聲特有功能,不需要專門設(shè)計驅(qū)動程序,接口簡單,成本低。 Abstract: Aiming at the problem of the digital ultrasonic diagnostic imaging system keyboard with RS232 interface currently used couldn?蒺t set the BIOS when the PC boot, this paper proposed a design method of PS2 keyboards. Based on W78E052D microcontroller,designed eight TGC potentiometers information acquisition circuit with 8-channel serial A/D converter, potentiometer position information sent out with keyboard scan code sequentially.The control circuit based on XC9536 CPLD is used for converting the mechanical actions of the encoders into the signals that can be identified by the MCU, software received interrupt information and equivalently treatmented as key. The results show that the BIOS can be set to meet the boot, ultrasound specific functionality can be achieved at the same time, it does not require specially designed driver,the interface is simple and low cost.
