The invention discloses a remote vehicle detection and alarming device, which relates to the detection and alarming device and aims to solve the problem that the conventional vehicle failure checking device cannot detect electronic failures of electrical appliances of a vehicle in real time. The satellite positioning signal input end of a central processing module is connected with the satellite positioning signal output end of a satellite positioning module; the mobile communication signal output and input ends of the central processing module are connected with the mobile communication signal input and output ends of a mobile communication module; a burglary prevention triggering signal output end of a burglar alarm module is connected with the burglary prevention triggering signal input end of the central processing module; and the power supply end of a power supply module is simultaneously connected with the receiving end of the central processing module, the receiving end of the satellite positioning module, the receiving end of the mobile communication module and the receiving end of the burglar alarm module (6). The remote vehicle detection and alarming device has the advantages of vehicle electrical appliance electronic failure real-time detection, high alarming speed, accurate vehicle positioning data and the like, and can be widely applied to various types of vehicles.

The invention discloses a positioning system and positioning method based on multi-sensor data fusion. Encoders and omnidirectional wheels are fixed on encoding disk frames. Main rotation shafts of the omnidirectional wheels are connected with rotation shafts of the encoders. The three encoding disk frames are fixed on a fixing holder. Included angles between vertical planes in which axes of the three encoder rotation shafts are 120 degrees. The three omnidirectional wheels contact with a moving ground at the same time. A three-encoding-disk whole field positioning system is employed, when a mobile robot moves, the three omnidirectional wheels are passively rotated, and robot omnidirectional movement data can be accurately obtained, so the influence that positioning is inaccurate resultingfrom angle drift of a gyroscope is reduced. Change condition of a to-be-positioned robot at three degrees of freedom is obtained through utilization of an updating formula for three encoding disk coordinates, relative positioning is realized, precision of the positioning system when the robot is in a high speed driving state and under different site conditions is improved, and according to the system and the method, in practical operation, relatively accurate positioning data can be obtained for a sudden event or ground condition.

The invention discloses a storage and stacking goods positioning method and device, which are used for accurate positioning of storage and stacking goods. The storage and stacking goods positioning method includes: dividing the target area into a two-dimensional grid according to preset division rules, and selecting reference points on the two-dimensional grid; comparing the first measured coordinates of each reference point with the actual coordinates , obtain the vector error of each of the reference points; obtain the second measurement coordinates of the target goods in the target area, and determine the reference point corresponding to the target goods; Second, the measurement coordinates are corrected to obtain the positioning coordinates of the target goods. By adopting the technical solution of the present invention, the reference point vector compensation is carried out for the measurement and positioning of storage and stacked goods, thereby reducing the positioning error of the goods, improving the monitoring ability of special items such as dangerous chemicals, and eliminating potential safety hazards in the storage and stacking process.
