Abstract

This utility model is combined vehicle flowrate monitoring and feedback system for a kind of bridge, it is possible to monitoring bridge vehicle flowrate, gross vehicle load and overload of vehicle situation, it is judged that bridge uses state at present, and is reacted on traffic light.It is made up of end of the bridge Weight Watcher system, processor, controller, volume of traffic signal lights and long-range monitoring computer.Wherein end of the bridge Weight Watcher system is made up of armored concrete weighbridge, rotatable camera, vehicle Automatic camera.Armored concrete weighbridge is divided into upper bridge side, Xia Qiao side (or being end of the bridge side, bridge caudal) two groups, each track has a weighbridge, it is simple to calculate respectively.Rotatable camera, traffic light, be arranged on the compound rod of Shang Qiao and Xia Qiao side.Between end of the bridge Weight Watcher system, processor, controller, use wired connection, between these three part and remotely monitoring computer, use network to connect.This utility model low cost, simple installation, effectively solve bridge vehicle flowrate and monitor feedback problem in real time, the person that makes bridge inspection and maintenance, vehicle supervision department and driver learn bridge service condition the very first time.

Description

Bridge is combined vehicle flowrate monitoring and feedback system

Technical field

A kind of monitoring system of this utility model design, especially a kind of bridge is combined vehicle flowrate monitoring and feedback system, belongs to In monitoring system technical field.

Background technology

At present, China has substantial amounts of bridge to enter a detection and reinforcing stage, has and send out when bridge collapse, malicious event Raw, threaten safety of person vehicle constantly.And the bridge of currently the majority impaired with the overload of gap bridge automobile, excess closely related, although There is compulsory measure in country, carrys out specification overload problems, but the consciousness that people are in this respect is the thinnest, in interests and fluke mind Ordering about under, drive on the bridge.Bridge 1 twice overload under the influence of, do not have the biggest problem, but at vehicle flowrate relatively Big region, overload problems just should not be underestimated.Single monitors vehicle flowrate and ignores the weight by vehicle, and overload still can be made existing Picture frequency is sent out, and bridge likely can be normal at vehicle flowrate, but overload on the high side in the case of damage.

The utility model of Patent No. CN200920161631.6: a kind of Intelligent monitoring system for bridge, and most of bridge Monitoring system is the same, the most passive monitoring bridge change in stress, structure, feeds back in time, but after test problems Implement the means such as reinforcing, traffic control, expend the time oversize, relatively costly；The reality of Patent No. CN200910151427.0 With novel: a kind of Intelligent bridge monitoring method based on Traffic flux detection, predict its shadow to bridge by traffic monitoring Ring, so control traffic, but its time span is the longest, and the volume of traffic representativeness of certain period is not strong, causes institute The measure taked can not tackle all situations.

Summary of the invention

The technical problems to be solved in the utility model: this utility model provides a kind of bridge and is combined vehicle flowrate and monitors and is System, is affected by the problem overloaded and excess vehicle is passed a bridge solving bridge, it is achieved the life to bridge, vehicle flowrate Reasonable distribution, it is to avoid because driver is unclear to the actually used situation of bridge, and in the case of not allowing, upper bridge of driving, Bridge machinery personnel and the traffic planninng personnel understanding to bridge working condition it have been also convenient for simultaneously.

This utility model solves the technical scheme that its technical problem is used: bridge is combined vehicle flowrate monitoring system by end of the bridge Weight Watcher system, processor, controller, volume of traffic signal lights and long-range monitoring computer composition.End of the bridge Weight Watcher system It is made up of armored concrete weighbridge, rotatable camera, vehicle Automatic camera.End of the bridge Weight Watcher system, processor, control Between device processed, use wired connection, between these three part and remotely monitoring computer, use network to connect.Divide at end of the bridge, bridge tail Two groups of weighbridges, specific size are not disposed to determine according to the general vehicle flowrate of span of bridge and bridge in each track；End of the bridge weight Amount monitoring system is also configured with high definition rotatable camera and vehicle Automatic camera.Processor and controller are at left and right line End of the bridge side, accepts bridge by wire cable and leads to the information of Weight Watcher system, and controls traffic light and make a response.With The information collected is transferred to long-range monitoring computer by network signal by Shi Qiaotou Weight Watcher system, processor, remotely supervises Controller can also actively be handled by control computer, and then makes traffic light send reaction.

The beneficial effects of the utility model: low cost, simple installation, effectively solution bridge vehicle flowrate monitor feedback in real time and ask Topic, the person that makes bridge inspection and maintenance, vehicle supervision department and driver learn bridge service condition the very first time.

Accompanying drawing explanation

With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.(use at single span, two-way bicycle road freely-supported On beam bridge)

1. armored concrete weighbridge group in figure, 2. rotatable camera, 3, vehicle Automatic camera, traffic light, 4. processor, the expansion joint of controller (being placed on same position) 5. armored concrete weighbridge both sides.

Detailed description of the invention

At Fig. 1, in 2, armored concrete weighbridge group 1, rotatable camera 2, vehicle Automatic camera and traffic Signal lights 3, processor and controller 4, and remotely monitoring computer constitutes this utility model entirety.Wherein, end of the bridge weight prison Ore-controlling Role is made up of armored concrete weighbridge, rotatable camera, vehicle Automatic camera.

When vehicle travels upper bridge, and the weighbridge at end of the bridge, end of the bridge weighbridge has an increment, under processor immediate record Increment size, vehicle Automatic camera will be that the car opening weighbridge is taken pictures automatically, records its model, size, car plate etc. basic Information, the vehicle that weight ratio is bigger, processor meeting separate marking (such as more than 15t), record is for traffic administration personnel inquiry.When Under vehicle during bridge, will also pass through the weighbridge that opposite bank end of the bridge goes out equally, at the end of the bridge of opposite bank, weighbridge has same increment.So, processor The upper bridge side weighbridge increment total amount received, deducts Xia Qiao side weighbridge increment total amount, the most just draws and now travels gross vehicle on bridge Weight m, thus compared with value M after the factor reduction such as Bridge Design bearing load limit elapsed time, material, environment, sentence Bridge cut-off beam operation state now, such calculating is carried out once by the every 5s of processor.If (i.e. m/M≤a in good condition₁), then Processor conveys information to controller, and controller controls traffic light and shows color of can passing through (can be green)；If state one As (i.e. a₁＜ m/M≤a₂), then processor conveys information to controller, and controller controls the traffic light current face of display deceleration Color (can be yellow)；If relatively hazardous (the i.e. a of state₂＜ m/M), then processor conveys information to controller, and controller controls traffic Traffic light system is closed to traffic color (can be red), it is recommended that take a₁=0.6, a₂=0.8.

Meanwhile, processor also the increment of throughput both sides can produce number of times, calculates the vehicle currently travelled on bridge Number, it is judged that jam situation.During whole, bridge leads to the information of Weight Watcher system and processor and all can be transferred to remotely monitor Computer, long-range monitoring computer can also convey information to controller, directly handle traffic light and rotatable camera.
