【Abstract】 In this article the TR40-16 ultrasonic sensor and AT89C2501 SCM are used to develop the detecting distance system for backsight obstacle of agro-machinery team. The article introduce the principle of the system, correlated the circuit scheme and software flow chart. The range of detecting distance is 0.13~10 meters which can satisfy the request of engineering application.更多还原
