1、Ultrasonic ranging system designPublication title: Sensor Review. Bradford: 1993.Vol. ABSTRACT: Ultrasonic ranging technology has wide using worth in many fields, such as the industrial locale, vehicle navigation and sonar engineering. Now it has been used in level measurement, self-guided autonomou

2、s vehicles, fieldwork robots automotive navigation, air and underwater target detection, identification, location and so on. So there is an important practicing meaning to learn the ranging theory and ways deeply. To improve the precision of the ultrasonic ranging system in hand, satisfy the request

3、 of the engineering personnel for the ranging precision, the bound and the usage, a portable ultrasonic ranging system based on the single chip processor was developed. Keywords: Ultrasound, Ranging System, Single Chip Processor 1. Introductive With the development of science and technology, the imp

However, due to historical reasons many unpredictable factors in the synthesis of her time, the city drainage syst

5、em. In particular drainage system often lags behind urban construction. Therefore, there are often good building excavation has been building facilities to upgrade the drainage system phenomenon. It brought to the city sewage, and it is clear to the city sewage and drainage culvert in the sewage tre

Mobile robots designed to clear the drainage culvert and the automatic control system Free sewage culvert clear guarantee robots, the robot is designed to clear the culvert sewage to the core. Control system is the core component of the deve

A principle of ultrasonic distance measurementThe application of AT89C51: SCM is a major piece of computer components are integrated into the chip micro-computer. It is a multi-interface a

8、nd counting on the micro-controller integration, and intelligence products are widely used in industrial automation. and MCS-51 microcontroller is a typical and representative. Microcontrollers are used in a multitude of commercial applications such as modems, motor-control systems, air conditioner

9、control systems, automotive engine and among others. The high processing speed and enhanced peripheral set of these microcontrollers make them suitable for such high-speed event-based applications. However, these critical application domains also require that these microcontrollers are highly reliab

10、le. The high reliability and low market risks can be ensured by a robust testing process and a proper tools environment for the validation of these microcontrollers both at the component and at the system level. Intel Plaform Engineering department developed an object-oriented multi-threaded test en

11、vironment for the validation of its AT89C51 automotive microcontrollers. The goals of this environment was not only to provide a robust testing environment for the AT89C51 automotive microcontrollers, but to develop an environment which can be easily extended and reused for the validation of several

12、 other future microcontrollers. The environment was developed in conjunction with Microsoft Foundation Classes (AT89C51). 1.1 Features * Compatible with MCS-51 Products * 2Kbytes of Reprogrammable Flash Memory Endurance: 1,000Write/Erase Cycles * 2.7V to 6V Operating Range * Fully Static operation:

13、0Hz to 24MHz * Two-level program memory lock * 128x8-bit internal RAM * 15programmable I/O lines * Two 16-bit timer/counters * Six interrupt sources *Programmable serial UART channel * Direct LED drive output * On-chip analog comparator * Low power idle and power down modes 1.2 Description The AT89C

14、2051 is a low-voltage, high-performance CMOS 8-bit microcomputer with 2Kbytes of flash programmable and erasable read only memory (PEROM). The device is manufactured using Atmels high density nonvolatile memory technology and is compatible with the industry standard MCS-51 instruction set and pinout

15、. By combining a versatile 8-bit CPU with flash on a monolithic chip, the Atmel AT89C2051 is a powerful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications. The AT89C2051 provides the following standard features: 2Kbytes of flash, 128bytes of RAM, 15 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt architecture, a full duplex serial port, a precision analog comparator, on-chip oscillator and clock circuitry. In addition, the AT89C2051 is designed with static logic for operation down to zero freque
