Detailed Description [0015] As shown in Fig.l, a movable overbridge system includes a bridge and ladders which are mounted on the both sides of the bridge. The bridge includes four columns 2, and an overbridge plate 3 mounted in the middle of four columns 2. A platform plate 4 which is mounted at the top of the columns 2, and fences 5 are arranged surrounding the platform plate. A roller wheel 14 is mounted at the bottom of each column 2. The lower parts of the two columns 2 on the same side of the street are connected by a crossbeam 18. The lifting jacks 12 are fixed at the both ends of the crossbeam 18.
[0016] As shown in Fig.4 and Fig.5, a power equipment is mounted on the crossbeam 18. The power equipment includes a motor 10, and a gearbox 11 is connected with an output shaft of the motor 10. An output shaft of the gearbox 11 is connected with the roller wheels 14 by a chain drive 13.
[0017] As shown in Fig.3, in order to enhance the robustness of the bridge, without any influences on the traffic under the bridge at the same time, the support devices are provided among the overbridge plate 3, the crossbeam 18 and the lower parts of the two columns 2 on the same side of the street. There are also support devices among the overbridge plate 3, the platform plate 4 and the upper parts of the columns 2. In the embodiment, the support devices include a horizontal bar 8, a vertical bar 7, and a diagonal bar 6. The horizontal bar 8, the vertical bar 7, and the diagonal bar 6 are interlaced and fixed together to support the bridge.
[0018] As shown in Fig.2, in order to facilitate pedestrians entering the overbridge from all the directions, there are four ladders 1, which are symmetrically arranged on both sides of the bridge.
[0019] As shown in Fig.6 and Fig.7, the ladder 1 includes an internal ladder and an external ladder which is mounted under the internal ladder. The internal ladder and the external ladder both include a ladder frame 1-1, footboards 1-2 which are mounted on the ladder frame 1-1 sequentially. Handrails 1-3 are mounted at the outer end of the ladder frame of the external ladder. An external pipe and an oil cylinder are fixed at the both ends of the ladder frame of the internal ladder, and an internal pipe is correspondingly fixed at the both ends of the ladder frame of the external ladder. The internal pipe is inserted into the external pipe. The oil cylinder body is fixed on the ladder frame of the internal ladder, and the piston of the oil cylinder is connected with the ladder frame of the external ladder. The retraction and extension of the oil cylinder are controlled by the data processing unit. When the pedestrian flow is heavier, the extension of the oil cylinders located at the both ends of the ladder frame is controlled by the data processing unit. The external ladder is extended under the control of the oil cylinders, and the width of the ladder is increased to facilitate the pedestrians crossing quickly. When the pedestrian flow is lighter, the retraction of the oil cylinders located at the both ends of the ladder frame is controlled by the data processing unit. The occupation area is thus reduced, and the oil cylinders at both ends of the ladder frame move synchronously.
[0020] The upper end of the internal ladder frame is hinged on the columns, and the oil cylinders are vertically fixed on the crossbeam. The retraction and extension of the oil cylinders are controlled by the data processing unit. When the overbridge needs to be moved, the retraction of the oil cylinders is controlled by the data processing unit, and the bottom of ladder is away from the ground. When the overbridge is stationary, the extension of the oil cylinders is controlled by the data processing unit, and the bottom of ladder attaches on the ground.
[0021] As shown in Fig.2, a rest platform is provided for the pedestrians. The pedestrians enter into the platform plate from the entrance though the platform stairs 9. The rest area 20 is set on the platform plate 4 for the pedestrians. In addition, solar panels 19 are arranged on the platform plate 4, and the storage battery 16 is charged by the solar panels 19 through the solar controller. The storage battery 16 is also under the overcharge and over-discharge protection by the solar panels.
[0022] For the convenience of pedestrians at night crossing through the overbridge, there are a plurality of lights arranged on the bridge, and the lights are charged by the storage battery 16.
[0023] As shown in Fig. 8, a control unit is connected with the motor. The control unit includes a video capture device, a data acquisition and analysis unit, a data processing unit, a monitoring unit, and an execution unit. The video capture device, the data acquisition and analysis unit, the monitoring unit, and the execution unit are respectively connected with the data processing unit. Wherein, the real-time video image information of the pedestrian flow is collected by the video capture device, and the video image information is transmitted to the data processing unit and the monitoring unit respectively. The data acquisition and analysis unit includes sensors which are used to sense the signals from the character elements of people and a data acquisition unit which can obtain the statistical data after collecting the signals from the sensors. After the data acquisition unit gets the statistical data, then statistical data is transmitted to the data processing unit. The real-time video image information from the video capture device and the statistical data from the data acquisition and analysis unit is received and processed by the data processing unit to obtain the data of pedestrian flow. Then, the data of pedestrian flow is sent to the monitoring unit. After the data of pedestrian flow is received from the data processing unit, the data is stored and displayed by the monitoring unit. The real-time video image information from the video capture device is received and real-timely monitored by the monitoring unit. Execution unit executes actions according to the instructions from the data processing unit.
[0024] In the embodiment, the lifting jacks 11 are automatic hydraulic lifting jacks. The driving mechanism is controlled by the data processing unit 17 to lift or lower the automatic hydraulic lifting jacks. The data processing unit 17 and the storage battery 16 are mounted on the crossbeam 18, as shown in Fig.5.
[0025] Working process:
Guiderails 15 are arranged on the roads, and the movable overbridge of the invention is mounted on the guiderails 15 by the roller wheels 14. The overbridge can move along the guiderails 15. The real-time video image information from the video capture device and the statistical data from the data acquisition and analysis unit are received and processed by the data processing unit, to obtain the data of pedestrian flow. Then, the data of pedestrian flow is sent to the monitoring unit. After receiving the data of pedestrian flow from the data processing unit, the data is stored and displayed by the monitoring unit.
[0026] When the pedestrian flow of this crossing collected by the video capture device and the data acquisition and analysis unit is heavier, the overbridge does not need to be moved, then the driving mechanism is controlled by the data processing unit to lift the automatic hydraulic lifting jacks up, so as to support the whole overbridge. The load of the roller wheels is thus reduced to prolong the service lifetime.
[0027] When the pedestrian flow of another crossing collected by the video capture device and the data acquisition and analysis unit is heavier, the overbridge needs to be moved. Then the driving mechanism is controlled by the data processing unit to lower the automatic hydraulic lifting jacks down. Next, the execution unit is controlled by the data processing unit to start the motor. The gearbox and the chain drive are controlled by the motor to move the whole overbridge to the another crossing where the pedestrian flow is heavier.
