A kind of stopping guide system based on dynamic statistics
Technical field
The present invention relates to stopping guide technical field, particularly to a kind of stopping guide system based on pre-statistics.
Background technology
Parking lot guidance system is primarily adapted for use in large and medium-sized underground parking, is widely used in the Public Parkings such as government house, large hospital, railway station and shopping center.Its main operational principle is to send ultrasound wave from top to bottom according to ultrasonic detector, detection roof and the echo on ground, it is possible to be correctly detected out each parking stall with or without vehicle, then the information of each parking stall Parking situation is passed to control computer by network line, computer passes through software processes, and guiding signal is passed to guiding indicator.Indicator guides driver to be quickly found out room.At present, parking lot guidance system mainly includes following subsystem:
1. data collecting system: current parking space state is judged by parking stall each in parking lot ultrasonic stall installed above information acquisition device;2. data transmission system: data are transmitted based on the communication protocols such as Ethernet, CAN, RS485, Wiegand, SPI, the parking stall data communication being mainly used between information acquisition terminal station of car parking and center management system;3. background server system: background server is the data center of whole system, receives, stores and processes the real time information on each parking stall, and set up data channel with various e-platforms, carry out information reception and data publication;4. data distribution system: issue data by LED screen, informs that the information such as distribution, route or travel by vehicle and vacant parking stall number are imported and exported in driver's free parking spaces, parking lot.
For existing parking lot guidance system, it is exactly that control centre is according to the Parking situation guide car main separation parking spot on parking stall briefly.But this mode have ignored on the passage of parking lot, not yet parks complete vehicle, it is easy to occur the vehicle commanded to drive to the most occupied situation in parking stall after presumptive area.
Domestic disclose many relevant parking lot guidance system patented technologies, such as:
