【正文】 56 by the data bus line send into 74 Ｌ Ｓ 165 the output of speech sound that gets position. In this design, it is for door , backing a car detection adopted the ＯＲＤ 226 dry spring flat switch sensors. The spring flat switch sensor is a kind of magic drive type switch, which sport partial qualities are little ,and rapid that natural frequency respond speed high and service life grows , even if in the place in which automobile and trolleybus often have vibration , using fully , especially be used in being the sensor with the monitor of relevant automobile extensively part. For the engine machine oil the detection of oil quantity and braking oil quantity adopt ＣＥ 41 5 type floats spring flat liquid position sensor. Measuring the temperature of cooling fluid to use thermistor type liquid use temperature sensor. With the negative thermistor NTC of temperature coefficient, its temperature value and simulated voltage signal bee inverse ratio. Imitate voltage signal to go through condenser strain the INO simulated signal passageway that sent into ADC0 809 after wave. When engine preheats , engine water is warm to be 70 to take to show degree, in the data memory in single flat machine, stocking data is pared , after contrast report to alarm the circuit silent light report to the police. Along with the work of unceasing engine, the water warm beginning of engine goes up gradually, when water is warm to exceed 95 to take to show degree only flat microputer drive report to alarm circuit report to alarm. Reminding the cooling system of driver notice engine the 傳感器 程序存儲(chǔ)器 電子控制器 語言數(shù)據(jù)存儲(chǔ)器 語音合成電路 3 change of temperature. The weared out condition of the detection automobile braking friction flat uses the wear detection sensor. When installing maked friction flat sensor Ｕ the top of word shape the wear limit location that locates in brake brake pad on, when friction flat wear goes to assigned limit Ｕ word shape part have been ground to break, circuit break open. At the same time, this unusual signal will be sent into the single flat microputer. For the detection driver, whether drink choose the semiconductor gas sensor that applies to ethanol gas detection , when the alcohol content in the air of driver39。s application scope increase , can say that it can satisfy the most of application occasions absolutely. MCS51 that is the major parts of personal puter integrated in a heart flat on, make data deliver distance shorten greatly, reliability is higher , traversal speed more piece. Since belonging to chip the personal puter that melts , each function parts structure and the layout in chip reach optimization, the ability of interference rejection strengthens , working is also stabilized relatively. Therefore in industry measure the controlling system, using the only flat microputer is the most ideal option. The single flat microputer belongs to the typical embedded system, so it is low end control systematic best device. 8051 is the typical product of MCS51 series single flat mictoputer, we go on with the type of this representative, which is systematic to explain. 8051 single slices microputer contains the central processing unit and program memory ( ROM ) , data memory ( RAM ) , timer / counter, parallel inputs or outputs(I/O) and serial interface with suspend few big units such as system and the 3 big bus lines such as data bus line, address bus line and control bus , we differentiate explanation: Central processing unit: Central processing unit( CPU ) is the key parts of the entire single flat microputer, which is the processor of 8 data widthes , can handle the 8 data or code of binary system, the plete operation and control input export function etc. And working CPU takes the responsibility for controling, manding and managing entire unit system to coordinate operating.
