Technical field
The present invention relates to a kind of intelligent mobile robot; particularly a kind of can independently the walking; autonomous classification and detection impact point; and adopt communication testing result to be dealt into the mobile phone or the computer of binding; and the family expenses that can receive from the steering order of mobile phone or computer move the security robot, belong to the service robot technical field.
Background technology
Modern urban family neighbourhood is unfamiliar with more, and the work hours are nobody home mostly, and the member all goes out when family, and when perhaps leaving teenage children, patient and handicapped old man in the family, it is particularly important that safety problem seems.Current security Study on Technology is awfully hot, numerous monitoring series products has appearred, common have monitoring camera, coal gas detection instrument, a broken detection instrument of glass etc., and can with the networking of sub-district safe examination system, be used to realize monitoring and warning under the abnormal conditions such as illegal invasion, fire.Though these conventional cell monitoring systems can play certain deterrence and preventive effect, but also exist some shortcomings: the one, this safe examination system generally is provided in newly-built high-grade intelligent residential district, the sub-district improvement cost height of originally building up also can destroy the finishing of resident family; Moreover these supervisory systems have certain dead band, also may be destroyed, and also these all are fixed monitoring means, can not monitor the every nook and cranny in room.
The security robot can remedy above-mentioned defective well: robot can walk everywhere, can play the effect that replaces the people to observe everywhere, can allow robot regularly or monitor key position randomly; The intellectual technology that robot possessed can realize that dynamic object is captured and tracking, and the object of activity is taken pictures or recorded a video; Robot can also with data storage or send to the mobile phone of binding or remote computer so that owner understands the situation in the family in real time.Even the family of supervisory system is being installed, robot also can with existing camera, sensing system networking, search abnormal information, in time feed back to owner, existing static supervisory system is played a role more effectively.
The robot system of having mentioned suitable family monitoring usefulness in some researchs is arranged at present.Patent 200420053492.2 discloses a kind of camera, smoke transducer, glass break sensors of having, and by monolithic processor controlled security robot, information wireless such as image can be transferred to centralized control room.Patent 200520087230.2 discloses the gsm communication control circuit of using on a kind of security robot.Patent CN201010543931.8 discloses the interactive system of a kind of iPhone of being applicable to smart mobile phone and robot, can be by the action of smart mobile phone control robot.Patent CN200920294316.0 discloses the crusing robot of a kind of GPS of employing location, because the bearing accuracy limitation can only be applied to the open air.Patent CN200910199945.X discloses a kind of a plurality of household robot systems that connect by wireless ethernet, is suitable for the group collaboration of robot.Patent CN201010046514.2 discloses the many sensory robot systems that a kind ofly have camera, sound collector, keep away barrier sensor etc.Above patent has all related to the practical technique of family expenses security robot in one aspect; but significant limitation is all arranged, do not realize robot intelligence fixed point monitoring in the family, monitor message can not be fed back to the user in real time; can not network poor practicability with other smart machines.
The present invention is intended to solve the gordian technique in the practical application of family expenses security robot: seek and the locating and monitoring target; and with monitored results be wirelessly transmitted to mobile phone or the band interface the computer terminal; and can adopt the mode of Internet of Things and other smart machines to network, make the security robot can really be applied to the real-time monitoring of family.
