Said wireless communication module is the wireless public network module, for example the GPRS communication module.
Connecting pipe, pressure transducer, lithium battery, wireless communication module, radio-frequency module, oiling kapillary, water level terminating machine, buoyancy switch, gravity switch are technique known contents before the applying date.
Using method of the present utility model is as follows:
1. with the wireless manual operation device waterlevel data of flood detector and alarm is proofreaied and correct;
2. use the computer that is inserted with radio-frequency card, the date between measuring point numbering, the communications parameter of radio frequency network setting flood detector and alarm are timely;
3. establish water gage glass at mountain torrents through the place, the flood detector and alarm is inserted wherein;
4. whether the flood detector and alarm regularly reports time on date and battery electric quantity and checks the flood detector and alarm working properly when flood does not take place;
The flood detector and alarm initiatively reports the time and intensity that flood takes place when 5. flood taking place;
6. in the non-inundation phase, the flood detector and alarm can be taken out, take back administrative authority, with anti-lost.
Said water gage glass can be arranged on the crag of flood process, tree or any firm part greatly, damages in case flood sweeps away the floating thing that comes, and length is determined according to flood depth of water maximal value, established a plurality of inlet openings on the water gage glass wall.
Characteristics of the present utility model are: 1. host computer is determined by collecting device by input flood detector and alarm numbering; 2. the flood detector and alarm belongs to self-powered intelligent " point-and-shoot " equipment, in the open air, work automatically under the unmanned situation about participating in; 3. the computer expert who is inserted with radio-frequency card crosses wireless radio frequency mode, and parameter is set in certain distance, need not to contact the flood detector and alarm; 4. when the inundation phase finishes, the flood detector and alarm conveniently can be taken away with anti-lost from water gage glass.
The beneficial effects of the utility model: each several part 1. of the present utility model all can be made in batches in factory, and on-site installation and maintenance are all very convenient using; 2. host computer can be gathered many flood detector and alarms, is determined by collecting device by the input numbering; 3. the pressure shield structure prevents the front end silting; 4. the oiling kapillary completely cuts off moisture and enters when guaranteeing the pressure transmission; 5. self-powered and battery saving mode, assurance equipment in the open air, long-time work automatically under the unmanned situation about participating in.
