Embodiment Construction

[0021] In the action control process of a mobile robot, it is necessary to determine the action route of the robot in the action process according to the environment in which the robot is located. For the collection of position information and obstacle information on the action route, a high-speed data collection system provided by the present invention is as follows: figure 1 shown.

[0022] According to a preferred embodiment of the present invention, the high-speed data acquisition system includes a control module, a distance calculation module, multiple signal transmitting modules, multiple signal receiving modules, multiple timing modules, and multiple pulse generating modules. For the connection relationship of each module, see figure 1 . The control module adopts FPGA.

[0023] Wherein, the control module controls the signal transmitting module to transmit ultrasonic waves, and the signal receiving module receives the reflected ultrasonic waves according to preset co...

Abstract

The invention provides a high-speed data acquisition system, aiming at improving the position information acquisition efficiency of a mobile robot; the high-speed data acquisition system is adopted to control actions of the mobile robot and comprises a control module, a distance calculation module, a plurality of signal transmitter modules, a plurality of signal receiver modules, a plurality of timing modules and a plurality of pulse generation modules. The high-speed data acquisition system has the beneficial effects: the acquisition control of analogue signals, namely, position information is realized by utilizing digital signals and the control flexibility is improved; the receiving frequency and pertinence of ultrasonic wave signals can be improved greatly on the basis of the control and regulation of ultrasonic wave frequency; the acquisition frequency of ultrasonic waves in the same direction is adjusted by the time difference between the transmitting time and the return time of the ultrasonic waves, the occupancy of resources of the control module can be reduced and the utilization efficiency of the resources of a robot control system is improved.

Description

technical field [0001] The present invention relates to the technical field of robot automatic control, and more specifically, to a high-speed data acquisition system. Background technique [0002] With the development of modern science and technology, mobile robots are becoming more and more intelligent, and the requirements for data sources and data processing speed are also getting higher and higher when they perform tasks. [0003] Existing methods for improving the data acquisition speed mainly focus on the improvement of the data acquisition circuit. For example, as a bridge between analog and digital signals, analog-to-digital converters are increasingly used. New theories and new algorithms emerging continuously at present, coupled with the improvement of the performance of digital signal processing devices, have promoted the development of data acquisition systems. At present, the rate of commonly used data acquisition systems is generally several MSps to hundreds...
