accompanying drawing illustrates:
Accompanying drawing 1 is the structured flowchart of the described road car flow harvester based on laser ranging.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with specific embodiment, a kind of road car flow harvester based on laser ranging of kind described in the utility model is further described.
The utility model proposes a kind of road car flow harvester based on laser ranging, this device can be arranged on the light pole of road both sides, Real-time Collection road car flow, and flow motor information is shared to car owner by network, car owner is helped to select feasible bypass route, avoid congested link, thus alleviate traffic pressure to a certain extent.
Embodiment:
A kind of road car flow harvester based on laser ranging described in the present embodiment, described road car flow harvester interval same distance is fixed on the light pole top in roadside; As shown in Figure 1, described road car flow harvester comprises: power transfer module, STM32 microprocessor, some laser modules, gsm module; Wherein, in described power transfer module link road lamp stand, electric wire is that whole device is powered, and described STM32 microprocessor is connected with described power transfer module, and simultaneously described laser module, gsm module are all connected with described STM32 microprocessor and communicate; Described STM32 microprocessor is master controller, is responsible for calculating laser from being issued to the mistiming returned, and is detected can collect the vehicle number passed through in the unit interval by continuous print; Described STM32 control gsm module by Real-time Collection to flow motor information be sent to far-end server by data network, connect upper far-end server for car owner by terminal devices such as mobile phones, utilize the flow motor information that this road car flow harvester gathers.
Based on the road car flow harvester of laser ranging described in the present embodiment, described power transfer module transfers the 220V alternating current in street lamp to 5V or 3.3V direct current, for whole device is powered.Described STM32 microprocessor is master controller, is responsible for calculating laser from being issued to the mistiming returned, thus calculates the distance of this road car flow harvester to road surface; When passing through without vehicle, this distance remains unchanged, otherwise for there being vehicle to pass through, until this range recovery is to time equal with the distance on road surface, thus is judged as that a car passes through, and is detected can collect the vehicle number passed through in the unit interval by continuous print.
Based on the road car flow harvester of laser ranging described in the present embodiment, the quantity of described laser module can increase according to the quantity of road track or reduce, three laser modules are provided with in the present embodiment, the laser head of these three laser modules can aim at three lanes road central authorities in the same way respectively, when without vehicle by time carry out system initialization setting, system now can be recorded to the distance of each bar road center; When have vehicle by time, device detects that distance shortens, and waits for when recovering after initial distance, has been judged as a car process.Described gsm module is connected by serial port with STM32 microprocessor, at interval of a period of time, by STM32, the information of vehicle flowrate calculated is announced gsm module and be sent to far-end server by data network, car owner user inquires about the information of vehicle flowrate in each section by far-end server in mobile phone A PP connection.
Above-mentioned embodiment is only concrete case of the present utility model; scope of patent protection of the present utility model includes but not limited to above-mentioned embodiment; any meet claims of the present utility model and any person of an ordinary skill in the technical field to its suitable change done or replacement, all should fall into scope of patent protection of the present utility model.
