Abstract
A traffic throughput monitor system is composed of traffic throughput signals pick-up devices and terminal signal processor. Said traffic-throughput signals can be transmitted from said pick-up devices to said processor via power transmission line, especially the one for road lamps. Its advantage is low cost.
Description
Technical field
The present invention relates to electronic technology field, relate in particular to a kind of traffic throughput monitor system.
Background technology
Along with development of electronic technology, the field of its application is also more extensive.At present, in order to understand the traffic in each highway section in real time, vehicle supervision department has adopted and has had additional the camera that is used to monitor traffic and vehicle peccancy situation in each highway section, camera can transfer to monitoring center by special line with the image information of gathering, and whether traffic and each vehicle that the managerial personnel of monitoring center just can understand each highway section easily according to the image information that receives exist situation violating the regulations.This special line that is provided with for images information is special has increased the implementation cost of this technology greatly, has limited generally applying of this technology, make vehicle supervision department can only be at important crossing or the location carry out the collection of respective image information.Like this, vehicle supervision department is difficult to grasp the traffic in local each highway section real-time and accurately, also just can't better guarantee the smooth and easy of each road section traffic volume.
Summary of the invention
The purpose of this invention is to provide a kind of traffic throughput monitor system, can provide the magnitude of traffic flow situation in each highway section real-time and accurately, and implementation cost is cheap.
The object of the present invention is achieved like this: a kind of traffic throughput monitor system, comprise magnitude of traffic flow signal pickup assembly and terminal signaling Integrated Processing Unit, magnitude of traffic flow signal pickup assembly is sent to the terminal signaling Integrated Processing Unit with the magnitude of traffic flow signal that collects through signal transmission line, and what described signal transmission line adopted is power transmission lines.
Described power transmission lines is a street lamp supply line.
Described magnitude of traffic flow signal pickup assembly is a signal transducer, signal transducer links to each other with power transmission lines by signal modulator, signal transducer exports the traffic flow information of gathering to signal modulator with digital signal, and is modulated into carrier signal by signal modulator.
Described terminal signaling Integrated Processing Unit comprises demodulator of PM signal PM, signal receiver and signal processing apparatus, demodulator of PM signal PM is demodulated to digital signal with carrier signal and delivers to signal receiver and receive, signal receiver is delivered to signal processing apparatus with the signal that receives again and is handled, and obtains traffic flow information.
Described terminal signaling Integrated Processing Unit also comprises sender unit, is used for the traffic flow information that signal processing apparatus obtains is launched.
Also comprise encryption mechanism in the described sender unit to circulation stream amount information to be launched.
By technique scheme as can be seen, the present invention has saved the cost that the magnitude of traffic flow is monitored greatly owing to adopted the existing power circuit as the data information transfer circuit, has reduced enforcement difficulty of the present invention.Application of the present invention can make vehicle supervision department can understand the magnitude of traffic flow situation in each highway section real-time and accurately, and the magnitude of traffic flow situation in each highway section of being grasped can be offered in real time the user who needs to understand this information, for user's trip brings great convenience, can effectively regulate simultaneously the vehicle flow in each highway section, make the traffic in each highway section more smooth and easy.
Description of drawings
Fig. 1 is a theory diagram of the present invention.
Embodiment
A kind of traffic throughput monitor system of the present invention, comprise magnitude of traffic flow signal pickup assembly and terminal signaling Integrated Processing Unit, magnitude of traffic flow signal pickup assembly is sent to the terminal signaling Integrated Processing Unit with the magnitude of traffic flow signal that collects through signal transmission line, what described signal transmission line adopted is power transmission lines, and especially is fit to adopt street lamp supply line.
Concrete enforcement of the present invention is described below in conjunction with the accompanying drawings, referring to Fig. 1: at first carry out the collection of traffic flow information among the present invention by a plurality of signal pickup assemblies, as the signal pickup assembly among Fig. 11, signal pickup assembly 2, signal pickup assembly n, signal pickup assembly can be photoelectric sensor, or electromagnetic sensor, or the infrared heat source sensor etc., sensor exports the traffic flow information gathered to separately signal modulator with digital signal, as the signal modulator among Fig. 11, signal modulator 2, signal modulator n, and be modulated into carrier signal by signal modulator, outwards transmit by power transmission lines, and receive by the terminal signaling Integrated Processing Unit, carrier signal can be square-wave signal, sawtooth signal etc., the frequency of carrier signal can be provided with as required, but can not be identical with the electric signal frequency transmitted in the power transmission lines.Described terminal signaling Integrated Processing Unit comprises demodulator of PM signal PM, signal receiver and signal processing apparatus, demodulator of PM signal PM is demodulated to digital signal with carrier signal and delivers to signal receiver and receive, signal receiver is delivered to signal processing apparatus with the signal that receives again and is handled, and obtains traffic flow information.
Terminal signaling Integrated Processing Unit among the present invention can also comprise sender unit, is used for the traffic flow information that signal processing apparatus obtains is launched, to offer the user who needs traffic flow information.For the transmission of carrying out traffic flow information targetedly also need be in sender unit to the encryption mechanism of circulation stream amount information to be launched, thereby just make the user who meets authority can carry out the reception of traffic flow information.
