On site bus multi- sensor amalgamation device

Abstract

The invention discloses a multi-sensor fusion device based on a field bus, which uses a processing unit as a core and comprises an analog signal acquisition unit connected with the processing unit, a sonar signal acquisition unit, a parameter storage unit, a standard digital communication interface unit and a field bus communication unit, wherein, the processing unit acquires various external sensor signals through the analog signal acquisition unit, the sonar signal acquisition unit and the standard digital communication interface unit, communicates an external device through the field bus communication unit, and completes a parameter storage in the device through the parameter storage unit. The invention realizes a multi-sensor fusion based on the field bus communication, has a reasonable design, rich standard interface resources, convenient expansion and low cost, and can be easily applied to an intelligent household service robot.

Description

technical field [0001] The invention relates to a multi-sensor device for a home service robot, in particular to a field bus multi-sensor used on an intelligent home service robot system to collect signals from multiple sensors and process the signals through field bus communication fusion device. Background technique [0002] In the intelligent household robot system, multiple sensors are required to complete the collection of surrounding environment signals. The existing sensor signal collection devices mostly use parallel structure communication or the expansion of multiple sensor signal collection devices, which is inconvenient for robots. The internal connection does not have good anti-interference performance, and the use of multiple signal acquisition devices at the same time increases the system cost and the difficulty of coordination between the devices. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies, the object of the pr...
