POSITION DETECTING DEVICE AND METHOD OF CONCRETE PUMP VEHICLE AND CONCRETE PUMP VEHICLE

摘要

A device and method for detecting position of the concrete pump truck and a concrete pump truck including the device for detecting position are disclosed. The device for detecting position of the concrete pump truck includes a processor (910), a time counter (920), a dynamic sensor (930) and at least two fixed-point sensors (940). The sending and receiving of the ultrasonic wave may be performed between the dynamic sensor (930) and the fixed-point sensors (940). The time counter (920) may obtain a transmission time of the ultrasonic wave in a predetermined path according to the moment when the ultrasonic wave is transmitted and the moment when the ultrasonic wave is received, and the predetermined path may be determined according to the position relationship between the dynamic sensor (930) and the fixed-point sensors (940). The processor (910) obtains real-time coordinate parameters, a real-time movement direction or a real-time movement velocity of the concrete outlet (E) in the reference coordinate system (O) according to a preset transmission velocity of the ultrasonic wave and the obtained transmission time. In the concrete pump truck, the intelligent control system may control the movement direction and the movement velocity of the boom distal end (20) according to the information obtained by the processor (910), so that the boom distal end (20) is positioned in a predetermined position to ensure a smooth concrete pouring work.
