Described 3G module comprises data collector and 3G module path computing unit. Path computing list whereinUnit needn't adopt special equipment, can have by DSP or MCU etc. the equipment reality of data plus and minus calculationExisting.
The operation principle of Reservoir Water Quality on-line monitoring system of the present invention is as follows:
First, in described data storage, preserve in advance the GPS information of all 3G modules. Suppose certain detectionThe 3G module of module X, after searching all 3G modules within the scope of predetermined 10KM, obtains these 3GUnique communication identifier information of module. Then, detection module X and these 3G modules communicate, to obtainThe duty of above-mentioned each 3G module. This duty self has by various sensor assemblies(for example, whether the level on transfer of data pin, for low level, passes for communication protocol or status informationSensor module is in idle) realize, can also be for example: after making in analog it send one group of data, energyAccess its Effective Numerical, judge that its duty is effective. In a preferred embodiment of the invention, theseSensor assembly adopts the sensor self with self-checking function, and therefore, it is more square that the acquisition of state will becomeJust. So far, this detection module X can obtain all in presumptive area (for example,, with this 3G module distanceThe region of 50m) in the duty of sensor assembly.
Next, according to above-mentioned duty, find each duty in normal sensor assembly,Calculate again which distance service device of these sensor assemblies working properly nearest. Determine (to be for example to detectModule Y) after, this detection module X is by self various data (these packet monitoring and that receiveDraw together the testing result of total phosphorus and total nitrogen testing result and each sensor assembly) determine according to total phosphorus and total nitrogen testing resultPriority send to detection module Y. Specifically, laid at reservoir multiple by total to communication unit and total nitrogenAfter phosphorus checkout equipment is integrated in the so multiple detection modules in a detection module, first 3G module is enteredThe work of row route discovery, thus determine modules optimal path (for example, this best to far-end serverPath is set up according to the length of route distance). When communication, the two or more 3G modules that communicate with one another are equalCarry out one to one or many-to-one transfer of data, that is, certain or some 3G modules is as transmitting terminal, and only hasA 3G module receives the described various data that this or these 3G module is sent. Like this, each detectionThe data that module sends not are the server that directly sends to far-end, have alleviated the operating pressure of server.Meanwhile, in the course of work of Reservoir Water Quality on-line monitoring system, total nitrogen total phosphorus checkout equipment all obtains separatelyTotal nitrogen total phosphorus testing result, in the time that each 3G module sends described various data first, each 3G moduleFirst the various data that receive are saved in the memory of self, then after described sign off first,From memory, again read the described various data that this receives, and according to wherein each total nitrogen total phosphorus inspectionThe size that exceeds standard of surveying result sorts, and determines the priority while next time sending data, and which first sendsThe data that detection module transmission comes, the data which detection module transmission of rear transmission comes. So, once upperWhile receiving described various data, according to last priority, send successively each and send to himselfThe order of described various data of detection module of described various data. If the detection mould that its medium priority is highPiece not yet completes and detects or do not receive, waits for, sends until receive the detection module that this priority is highDescribed various data till, then send the described various data of the detection module that priority is slightly low. Like this,Can guarantee that remote monitoring end or server obtain the number in the with serious pollution region of total nitrogen total phosphorus with the fastest speedAccording to.
Described sensor assembly comprises: blue-green algae fluorescent optical sensor, dissolved oxygen sensor, turbidity transducer, PHValue sensor, temperature sensor, conductivity sensor or water depth sensor, be integrated and be sealed in a sleeveIn, its sensing position is outside exposed, reserves expansion mouth simultaneously and is furnished with corresponding cleaning device.
