Background technology
In recent years, low-lying place exists the phenomenon of a large amount of ponding to happen occasionally under the city tunnel that each big city of China is caused by heavy showers and the viaduct, and the trend that grows in intensity is arranged.Whenever heavy rain is attacked, always have the big city to become the news report in " inland sea ", ponding have unexpectedly up to more than one meter, and can not in time drain for a long time, brought very large inconvenience for people's trip, unexpectedly cause pedestrian's death and disappearances when serious.Particularly on July 21st, 2012 the Beijing area rainstorm disaster, many viaducts cause traffic paralysis because of ponding, in various degree ponding appears in the part highway section, has caused the tremendous economic loss.
Bring the city seeping phenomenon of huge life and property loss to cause showing great attention to of the relevant government departments such as municipal administration, flood control, road administration to people.To actively build and manage the pumping equipment system on the one hand, build on the other hand the water on urban streets monitor and early warning system, also very necessary, it both can provide for the masses of trip the real-time information of road ponding, also for the decision-making body such as municipal drainage group provide the management and running support, and then provide travel guide by media such as broadcasting, TVs for the general common people.
Summary of the invention
The purpose of this utility model is exactly the problem that will solve the timely early warning of above-mentioned water on urban streets.
The technical solution of the utility model is: the other water level telemetering station of installing of the road of main easily ponding in the city, when ponding meets or exceeds the early warning water level of setting, send early warning by the LED display scene that connects, and the water level information that monitors is sent in real time the server workstation of accusing central station by the gsm wireless transmission mode, after the system software analysis processing, show with figure and forms mode intuitively.
Formed by a charge central station and a plurality of water level telemeterings station the water on urban streets early warning system (such as Fig. 1).
(such as Fig. 2) mainly is comprised of level sensor, control circuit board, wireless launcher, LED display and protection tube at the water level telemetering station; the ponding information in each highway section of main monitoring; send in real time ponding prompting by the LED display scene, and information exchange is crossed radio transmitting device be uploaded to the charge central station.
Accuse central station by relevant system software, reception is also processed the warning information of being sent by the water level telemetering station, and water accumulation level information is shown at display screen intuitively.
The utility model can be realized on-the-spot real-time early warning, has simultaneously the functions such as long distance wireless communication, teledata demonstration, thereby accomplishes the remote real-time monitoring water level information, for the decision maker of the departments such as municipal traffic offers help.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
1, system architecture
As shown in Figure 1, the utility model comprises that a charge central station and a plurality of water level telemeterings station (upper dotted line frame part among the figure) form.
When road ponding during to certain altitude, trigger level sensor, control circuit board obtains switching signal, process and conversion through signal, the ponding indication is sent at the LED display scene that is attached thereto in real time, synchronous signal sends on the server workstation of accusing central station by radio transmitting device, and carries out data Treatment Analysis and demonstration.
What the system software of server workstation adopted is the framework of client/server, comprise the functions such as data communication, storage, processing, data reproduction, figure demonstration, whole system software is workable, simple, intuitive, can show the information such as time, place, alarm water level of a certain monitoring point.
2, the water level telemetering station arranges installation
Select the place of an opposed flattened at the most low-lying place in early warning highway section, with installation of sensors in a vertical protection tube, as shown in Figure 2.
1) protection tube [1] material is stainless steel or PVC, has sufficient intensity to prevent from destroying, internal diameter 〉=10cm, highly 〉=150cm.
2) the liquid-level floater switch is a kind of fluid level controller spare simple in structure, easy to use, and it does not need to provide power supply, does not have complicated circuit, and it has less than common mechanical volume of switch, the advantages such as long working life.Select side-mounted liquid-level floater switch as sensor at this, horizontal setting is the early warning height of water level at protection tube [1] medial surface apart from floor level, according to actual needs free magnitude setting and height.As 3 K switch 1, K2 and K3 are set, highly be respectively 15cm, 25cm and 35cm.
3) LED display [3] is arranged on the remarkable position of road, is connected with float switch [2], and when water level goes up to switch [2] when locating, the trigger switch plugged makes the LED display [3] of connection bright, sends a warning.As when water level is between K switch 1 and K2, this highway section ponding of screen prompt surpasses 15cm, needs carefully current; When water level was between K switch 2 and K3, screen prompt ponding surpassed 25cm, and vehicle should not pass through; When water level when K switch 3 is above, screen prompt ponding surpasses 35cm, no through traffic for vehicle.
4) control circuit board [4] comprises logic gates, voltage transformation module, the parts such as RS232/RS485 communication module, power failure protection module.Control circuit board is used for processing switching signal, carries out showing by LED display [3] after the signal analysis and processing, and water level information is transferred to radio transmitting device [5].
5) radio transmitting device [5] comprises gsm module, and water level information is sent to the charge central station with the form of network or note.
6) firm banking [6] makes the stable low-lying place of road that is upright in of protection tube.
7) protection tube bottom [7] screen cloth, and leave certain distance with ground, in order to avoid foreign material enter the obstruction protection tube.
8) protection tube top [8] perforate makes in the pipe to keep balance with ambient pressure, allows water enter in the pipe smoothly, and installs capping additional, prevents that foreign material from entering in the pipe.
9) power supply [9] is the alternating current of urban operating mechanism power supply, is the device power supply after the voltage transformation module conversion in control circuit board [4].
Innovation
This utility model patent is a kind of water on urban streets early warning system, it has remedied the deficiency of water on urban streets early warning, and fully take into account terseness and practicality, adopted cheap float switch as level sensor, when reaching early warning value, water level shows in real time by LED display, and employing gsm wireless transmitting device remote transmission data, make the user can obtain relevant ponding information by above system indoor, the masses have greatly been made things convenient for, system arranges easily, and performance period is short, and cost is lower, practical, have promotional value.
