Description
Technical field
The present invention relates to public transport safety monitoring and technical field of image processing, particularly a kind of long-distance passenger bus overload monitoring system and method for supervising.
Background technology
As everyone knows, the vehicle of overload is prone to accidents, and particularly the long-distance passenger transportation vehicle in case have an accident, very easily brings out the dead group of group and hinders especially big serious accident, brings great loss and injury for country, the masses.Though country has put into effect a series of policies and regulations and prevented passenger carriage overloading, various places government has also formulated relevant system and has come passenger carriage overloading is managed, and this has reduced the overload phenomenon of passenger vehicle to a certain extent, and the overload phenomenon still remains incessant after repeated prohibition.Therefore, when taking the administrative supervision management, the phenomenon of eliminating passenger carriage overloading by scientific and technical means also has extremely important meaning and practicality.
At present, it mainly is the signal of human body when responding to through car door by certain sensing element that the overload of passenger vehicle is detected, and by Single Chip Microcomputer (SCM) system data is analyzed, handled, and judges whether passenger vehicle overloads.Sensing element commonly used mainly contains pressure sensor, human-body infrared sensing device, Photoelectric infrared switch etc.
As publication number is the Chinese invention patent prospectus of CN1877644A, a kind of overload monitoring system for coach bus is disclosed, comprise detector, the Single Chip Microcomputer (SCM) system that is connected with detector and warning that is connected with Single Chip Microcomputer (SCM) system and tape deck, this detector comprises some groups of Infrared Detectorss that are arranged at the pressure sensor under three grades of stepped surfaces of car door and are installed on ladders at different levels top successively, by to getting on the bus and the personnel of getting off respond to, counting, the statistics number of people in car, to judge whether overload, during adopts pressure sensor human body signal, when stepping on the cell pressure plate simultaneously, two or more passengers can leak the meter number, when striding across transducer and get on or off the bus, human body also can leak the meter number, on weight is placed transducer, can judge by accident to the people etc., so this method is not a kind of very effective and feasible method.If adopt infrared sensor or infrared array sensor, also there are several problems, when using independent human-body infrared sensing device, can not judge that the direction of getting on or off the bus can not determine that human body is in time that car door stops, when a plurality of passengers get on or off the bus simultaneously, can leak the meter patronage because block mutually between the passenger; When using the human body infrared array sensor, can not determine the time of human body in the car door stop, when getting on or off the bus simultaneously, a plurality of passengers also can count patronage by mistake; This is by the decision of the characteristic of transducer itself.
And publication number is the Chinese invention patent prospectus of CN1667374A, a kind of automatic identification system for vehicle overload is disclosed, should realize distinguishing by the image recognition subsystem to tested car category and specification, calculated with mathematical model by prior foundation obtains car load capacity value and unit length of wagon capacity value according to the front and back wheel pressure signal, judge comprehensively according to the car category, the specification information that obtain whether tested automobile overloads again, this system realizes complicated, in addition, according to the weight identification that overloads, be not suitable for personnel's overload of public passenger transport vehicle.
The overload monitoring system that adopts video monitoring is also arranged at present, as publication number is the Chinese invention patent prospectus of CN 2754929A, take visiting image storage and be sent to Surveillance center by camera, prevent the overload transportation, and by mobile communication GPRS or CDMA transmitted image information, realize remote monitoring, can not judge that carrying out this locality handles overload, volume of transmitted data is big, is difficult to use under present mobile communication environment.
Summary of the invention
In view of this,, the invention provides a kind of long-distance passenger bus overload monitoring system in order to address the above problem, can be in local real-time judge overload, volume of transmitted data is little.
