Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting protection domain of the present utility model.
Embodiment 1
The present embodiment scans 5 parking stalls so that the utility model to be described to use a scanning type laser sensor 101, but does not limit protection domain of the present utility model.The utility model discloses a kind of laser type parking site detecting system, with reference to Fig. 1, described system comprises: scanning type laser sensor 101, data transmission module 102, data analysis module 103.The straight line of the sector display plane formation crossing with ground of scanning type laser sensor 101 is positioned at the centre position 201 of tested multiple parking stall; Scanning type laser sensor 101 adopts suspension type mode to install, and installation site is positioned at above the middle parking stall of 5 parking stalls; When open parking ground uses, the scope scanned as required, i.e. the straight line of the sector display plane of scanning type laser sensor 101 formation crossing with ground is positioned at the length of 5 parking stalls, calculates setting height(from bottom) h; When non-open parking ground uses, setting height(from bottom) limits by parking lot height H, if parking lot height H is more than or equal to setting height(from bottom) h, can carry out normal mounting use; If parking lot height H is less than setting height(from bottom) h, setting height(from bottom) is up to H, if now horizontal direction space in parking lot is enough, installation site can be moved horizontally, adjust the setting angle of scanning type laser sensor 101 simultaneously, realize 5 parking stall scannings, if horizontal direction limited space, the parking stall number that now can detect is determined by parking lot height H, horizontal direction movable distance and single parking stall width.
When vehicle enters tested parking stall, when headstock or the tailstock touch the plane of scanning motion of scanning type laser sensor 101, this parking stall changes to the distance of scanning type laser sensor 101, and after vehicle stops, distance value is stablized.The scanning angle of scanning type laser sensor 101 is with corresponding distance value by data transmission module 102 real-time Transmission, and data transmission module 102, comprises all modes carrying out data transmission, for switch, but does not limit protection domain of the present utility model.Data analysis module 103, for embedded system, but does not limit protection domain of the present utility model, according to the distance value changed and corresponding scanning angle information, judges parking space state, can calculate the height and the width information of vehicle simultaneously.With reference to Fig. 1, data analysis module 103 can analyze, and there is car 2 parking stalls and 5 parking stalls, and 1 parking stall, 3 parking stalls and 4 parking stalls are idle.
