設(shè)計了水聲信號發(fā)生系統(tǒng)中的功率放大電路,可將前級電路產(chǎn)生的方波信號轉(zhuǎn)換為正弦信號,同時進行濾波、功率放大,使其滿足換能器對輸入信號的要求。該電路以單片機AT89C52,集成6階巴特沃思低通濾波芯片MF6以及大功率運算放大器LM12為核心,通過標(biāo)準(zhǔn)RS232接口與PC進行通信,實現(xiàn)信號增益的程控調(diào)節(jié),對干擾信號具有良好的抑制作用。經(jīng)調(diào)試該電路工作穩(wěn)定正常,輸出波形無失真,在輸出功率以及放大增益、波紋系數(shù)等方面均滿足設(shè)計要求。 This paper presented a design and implementation of underwater acoustic power amplifer. This circuit converted the rectangle signal generated by frontend circuit into the sine signal, then filtered and power amplification, it meets the requirements of the transducer.Included AT89C52, 6th order Butterworth filter MF6, hipower amplififier LM12.Communication with PC through the RS232 port. The signal gain is adjustable and could be remote controlled. It has a good inhibitory effect on the interference signal. After debugged, this circuit works stable, the output waveform has no distortion, it meets the design requirement in outprt power, amplifier gain and ripple factor.

基于LabVIEW和單片機的空調(diào)溫度場測量系統(tǒng)的研究:室內(nèi)溫度是空調(diào)系統(tǒng)舒適性的重要指標(biāo),對其及時、準(zhǔn)確地測量顯得非常重要。介紹單片機AT89C51 和數(shù)字式、單總線型溫度傳感器DS18B20 組成矩形測量網(wǎng)絡(luò)采集空調(diào)室內(nèi)40 點溫度,LabVIEW作為開發(fā)平臺,二者之間通過串口實現(xiàn)數(shù)據(jù)通信,利用LabVIEW強大的數(shù)據(jù)處理和顯示功能對采集的空調(diào)溫度場數(shù)據(jù)進行實時處理、分析和顯示,詳細(xì)介紹了系統(tǒng)的硬件結(jié)構(gòu)和軟件模塊的設(shè)計方案。關(guān)鍵詞:單片機;DS18B20 ;LabVIEW;串行通信 Abstract : Temperature is a very important criterion of air condition system′s comfort , so it is very significant to measure it accurately and real timely. This paper int roduces a data acquisition system of measuring 40 point s temperature for air condition room based on single wire digital sensor DS18B20 and microcont roller AT89C51 which are composed of rectangle measuring meshwork. The data communication between LabVIEW and microcont roller is executed via serial port ,and the temperature field data of air condition room are processed analyzed and displayed on LabVIEW. The hardware and software modules are also given in detail.Keywords : single chip ;DS18B20 ;LabVIEW; serial communication

中南賽區(qū)ACM競賽題 Description Given a two-dimensional array of positive and negative integers, a sub-rectangle is any contiguous sub-array of size 1*1 or greater located within the whole array. The sum of a rectangle is the sum of all the elements in that rectangle. In this problem the sub-rectangle with the largest sum is referred to as the maximal sub-rectangle.
