有利於對學員進行信號測量、信號傳遞、數據顯示、報警顯示、參數修改、報警閉鎖與喚醒、延伸報警以及模擬實驗等各方面的實驗和訓練,提高學員對現代化船舶自動化控制系統的維護和管理能力。It realizes the functions of storing and transferring the information of fire alarm, displaying time, scanning keyboards, the safe maintenance of system and so on. the part of wireless communication is controlled by at89c2051 mcu, mainly realizing transmitting and receiving data between controller and other detectors. the external signals received by a wireless module are transmitted to mcu through shaping circuit, and the signals of mcu are transmitted by a wireless module through tone modulation circuit
人機交互部分以單片機c8051f020為核心,為用戶提供一個良好的操作環境,實現了火災報警信息的存儲及調用、時間的顯示、鍵盤的掃描、系統的安全維護等功能;無線通信部分由單片機at89c2051來控制,主要實現控制器與其它探測裝置之間信號的無線發射和接收,無線通訊模塊接收到的外部信號經過整形電路送入單片機,單片機發出的信號經過音頻調制再由無線通訊模塊發送出去,這樣實現了數據的無線傳輸;本文還從節能的角度出發,兼顧性能的可靠性,提出了一種合理的無線火災報警的信息傳輸模式。The chip jk3ce that is one of micro - controllers in motorola 68hc08 family is used as control unit in this system. the zero crossing point of the back emf can be obtained by comparing the terminal voltage with the virtual neutral point, then using the software of the system can figure out the commutation period. the electronic commutation replaces the mechanical commutation in this way
本系統採用的控制晶元為motorola系列單片機中的jk3ce ,反電勢過零點可以通過比較電機端電壓和虛擬中點電壓來得到,將過零點信號送往單片機捕捉埠後由系統軟體來確定換相時刻,這樣就可以由電子換向裝置替代機械換相裝置,有利於提高系統運行的可靠性,並降低了系統維護的費用。At present such as inductance coil and etc. devices are adopted by most signal control systems to obtain field traffic information, which exists much deficiency both in installation, debugging, maintenance and technique
目前大多數交通信號控制系統採用了諸如感應線圈等設備來獲取現場交通信息,不管是從安裝維護方面還是從技術方面來講,都存在一定的不足。This paper demonstrates how to generate variable pwm waveform based on standard cpld device, the proposed circuit is incorporated with mcu to provide simple and effective solution for high - performance pwm converters. in the brushless model, the igbt ( isolated gate bipolar transistor ) switch state period table is gained by mc33035 which analyzes the signal of position feed - back
這部分功能在cpld器件中用vhdl語言開發實現,其isp (在系統編程)方式使得設計與維護都比傳統方法方便靈活,由於逆變器開關元件的觸發信號是由硬體來產生的,因此更容易實現準確的高速實時控制。For the high - speed digital signal processing, the structure of fpga and dsp is widespreadly adopted. dsp is more featured in the implementation of complicated algorithm, while field programming gate array ( fpga ) shows more advantage in its flexibility of design, simplicity of system configuration, modification and maintenance. in the paper, the hardware system of the spaceborne radar is based on the structure of fpga and dsp, of which the signal processing part is accomplished with one fpga chip and multi dsps
Dsp適合完成結構復雜的演算法;現場可編程邏輯陣列( fpga )適合完成高效、演算法固定的任務;與專用集成電路( asic )相比, fpga優點主要在於其很強的靈活性、可在線配置、修改和維護方便等優點。本文工程中的星載雷達信號處理和控制系統就是採用dsp + fpga的方式。其中信號處理採用的是xilinx公司的virtex -和virtex系列fpga和多片analogdevices公司的tigersharcts101的硬體電路結構。But transfers the oil to put the water station is the oil field production important link, how appropriately chooses, the design safely reliable, the data display accurate, the ease of operation nimble, is advantageous for the maintenance computer observation and control system, guaranteed the oil field measuring appliance, the microcomputer systematic security, is accurate, the steady movement, the optimized control, the realization safety in production and the energy conservation falls consumes, saves the manpower, the physical resource, enhances the working efficiency, and the production management level, is we at present in an oil field production important topic
