3, occupy the 5th in the world; Have 2163m per capita
3, only be equivalent to 1/4 of world's quantity per capita, rank after 100 in the global sequencing table.Along with the lasting raising of China's rapid development of economy and quality of the life, existing water resource quantity delivered is difficult to support ever-increasing demand; Rainfall amount is the key factor of water resource assessment, also is water circulation and isorrheic important parameter that the excavation of water resource potential depends on the measurement data of accurate rainfall amount.The instrumentation that detects rainfall amount is rain gage, and udometric accuracy is the technique guarantee of accuracy of detection.
Nineteen fifty-three, the homemade siphon rainfall recorder that detects rainfall amount automatically comes out, and replaces traditional artificial rain gage rapidly and is used widely; But siphon rainfall recorder needs could obtain the robotization requirement of rainfall intensity, the analog quantity recording mode incompatibility hydrology, weather information through converting, and measuring accuracy has much room for improvement in addition.Nineteen eighty-three, hydrological instrument factory in Chongqing releases domestic first platform commercialization tipping-bucket rain-gauge; At present, the hydrometric station is equipped with single tilting bucket rain usually; For considering of measuring accuracy, the weather station uses the higher double skip rain gage of more single tipping bucket precision mostly, but the structure complexity of instrument, O﹠M workload and expense are all on single tipping bucket.Tipping-bucket rain-gauge is simple in structure, presents rainfall amount with the pulse electrical signal form, is convenient to long-distance transmissions, for wired remote-transmission and wireless telemetering provide convenience; Tipping-bucket rain-gauge is born so far, all the time in occupation of udometric leading position.Although be no lack of the challenger, namely adopt the rain sensor of new principle: as the sensor based on perception rainfall such as electric capacity, resistance, ultrasound wave, optics; All inferior than tipping bucket type because of challenger's overall target (to the supply of environment requirement, power supply, measuring accuracy, total cost of ownership (TCO) etc.), the leading position that still can't shake tipping-bucket rain-gauge.

1Overturning constantly, and from the water receiving state to the waiting status transition, right small room then from waiting status to the water receiving status transition; t
2Constantly rainwater injects right small room, when the water receiving amount reaches predetermined value, right small room overturning, right small room enters the transition that returns to waiting status from the water receiving state, left small room then from waiting status to the water receiving status transition; Go round and begin again.On the tipping bucket sidewall of tipping-bucket rain-gauge magnet steel is housed, it stirs with tipping bucket, magnet steel is other inswept from tongue tube during the tipping bucket overturning, and the tongue tube on off operating mode is changed; Be the every overturning of tipping bucket once, tongue tube is just connected once, sends a switching signal (pulse signal), the rainfall amount of a resolving accuracy value of a pulse representative sensor.

Embodiment
As shown in Figure 1, single tilting bucket rain comprises tipping bucket rain sensor and signal acquisition process communication unit (be called for short number and adopt the unit) two parts; Single tilting bucket rain sensor is made up of the influent hopper 7 that connects rising pipe down, magnet steel 5, reed pipe plate 3,4, two double dry-reed pipes 2 of tipping bucket (two symmetrical small rooms that central dividing plate separates), set screw 6, circle bubble 8, tipping bucket block bearing 9, micro valve 10, bypass mozzle 11, valve opening and closing device 1; Set screw and circle bubble are the technical guarantees of rain gage installation site levelness; Two small rooms of tipping bucket respectively dispose a double dry-reed pipe 2, and the output terminal of double dry-reed pipe 2 links to each other with the input end that number is adopted the unit.Accept rainwater, weigh, measure at the water delivering orifice place that left and right two small rooms of tipping bucket 4 are in the influent hopper rising pipe in turn: make t
1The left small room amount of rainfall that the moment is positioned under the influent hopper water delivering orifice reaches design sensibility reciprocal, left small room overturning, drives the valve opening and closing device and closes micro valve; Through △ t=t
2-t
1Time is to t
2Constantly right small room go to the influent hopper water delivering orifice under, tipping bucket drives the valve opening and closing device and opens micro valve; Be temporarily stored in rainwater, t in the influent hopper in the △ t time
2The rainwater of accepting constantly imports right small room together, reaches the design sensibility reciprocal until the amount of rainfall of right small room, reappears left small room overturning process; Go round and begin again; Magnet steel 5 on the tipping bucket sidewall stirs with tipping bucket, and magnet steel 5 is other inswept from tongue tube, and the tongue tube on off operating mode is changed; The every overturning of tipping bucket once, tongue tube is just connected once, export one group of switching signal (two pulse signals of staggering the time) to the number adopt the unit, represent the rainfall amount of a resolving accuracy value.
As Fig. 2, shown in Figure 1, udometric tipping bucket 4 is bearing on the bearing 9, and two symmetrical small rooms that separated by central dividing plate constitute; When the water yield in the small room reached the design sensibility reciprocal, tipping bucket 4 overturn by rainwater gravity.The rain gage tipping bucket selects magnalium alloy in lightweight material to make, the Teflon (Polytetrafluoroetylene is called for short Teflon) of 10 microns of the side surface Pen Tu of catchmenting of influent hopper 7 and small room.Teflon is the solid material that the surface can be minimum, has excellent not viscosity (neither oleophylic, also not hydrophilic is difficult for by moistening surperficial easy cleaning), sliding, moisture resistance; Te Fu Long Tu layer has reduced udometric moistening loss, has reduced the excessive minus deviation of arid area rainfall measurement value; On the other hand, Teflon helps to overcome surface tension, acceleration water-sprinkling progress and the bold and vigorous cleanliness of water during the tipping bucket water-sprinkling, and elimination pouring small room leaves tail water and counts the error of rainfall amount next time.The alloy in lightweight material is made udometric tipping bucket, and the tipping bucket quality has only about 1/3 of conventional stainless steel; Be example with JDZ-1 type list tilting bucket rain, design sensibility reciprocal 3.14g (corresponding 0.1mm rainfall amount), the tipping bucket quality of the tipping bucket quality 100g of stainless steel, almag Pen Tu Teflon is 33g only.
The upset equation of tipping bucket can be expressed as:
M=J·dw/dt
In the formula
The turning torque of M--tipping bucket small room rainwater;
The moment of inertia of J--tipping bucket;
The flip angle speed of W--tipping bucket;
The flip-flop transition of t--tipping bucket.
By following formula as can be known, to the rain gage of a certain specific sensibility reciprocal, M is a determined value; The alloy in lightweight material is made tipping bucket, and the moment of inertia J of tipping bucket reduces; Dw/dt increases in inverse ratio, then the state of tipping bucket type machinery bistable state Weighing mechanism is changed △ t consuming time and is reduced, in the state conversion process rainfall Δ W of many meters reduce (argumentation that " background technology " the 5th section consulted in the definition of △ t, Δ W) thereupon, and it is poor namely to have reduced the device that tilting bucket rain picks up in the survey process.
As shown in Figure 3, the system of rain gage damper difference forms 11 by micro valve 10, valve opening and closing device 1, bypass mozzle; Micro valve is positioned at the 2cm place that makes progress, influent hopper rising pipe 7 bottoms, one end of bypass mozzle communicates with influent hopper rising pipe top sidewall, the other end communicates with influent hopper rising pipe bottom sidewall, and the upper and lower side of valve opening and closing device links to each other with tipping bucket 4, micro valve 10 respectively; Micro valve is selected micro ball valve for use, model WDF006M; Valve opening and closing device 1 is the mechanical linkage Ji Ju of a band spring, and when the tipping bucket overturning, tipping bucket utilizes the weight of self to drive mechanical linkage Ji Ju valve-off; Turn over φ angle (angle that tipping bucket type bistable state Weighing mechanism small room state △ switching time t turns over) after the tipping bucket overturning again, the valve opening and closing device is because of the recovery characteristic of spring Open valve again; Be temporarily stored in rainwater, the follow-up rainwater of accepting in the influent hopper in the △ t time, gather and import another small room, reach the design sensibility reciprocal until the amount of rainfall of this small room, reappear the overturning process of first small room; Go round and begin again.When valve opening and closing device and micro valve operate as normal, the bypass mozzle is inoperative; When in case valve opening and closing failure of apparatus or micro valve stop up, rainwater is walked around the small room that micro valve flows directly into tilting bucket rain through the bypass mozzle and is weighed, measures, the disappearance of valve damper difference function will make measuring accuracy descend this moment, but the bypass mozzle of setting up is maintained the fundamental measurement function of tilting bucket rain, and the bypass mozzle has improved udometric availability and reliability.
As shown in Figure 4, udometric number is adopted 4 switching signal processing modules (being one of them among the figure), CC2430 data processing module and the radio-frequency communication module that the unit comprises two double dry-reed pipes; The sidewall of tipping bucket left side small room sets up a magnet steel, goes alone reed pipe dislocation layout for two that specially join a double dry-reed pipe, formation double dry-reed pipe on the reed pipe plate relevant position, and the situation of the right small room of tipping bucket is as the same; Consider the terseness of statement, below discuss except special instruction is arranged, only launch around left small room; First switch output signal of going alone reed pipe is isolated U through photoelectricity in the double dry-reed pipe

As shown in Figure 5, two double dry-reed pipe output switching signals, signal are exported rainfall data and double dry-reed pipe operating mode behind the CC2430 data processing module; The CC2430 data processing module adopts two double dry-reed pipe Hu Jiao Suan methods, namely judge tongue tube operating mode, divide four kinds of patterns by the tongue tube operating mode--left and right sides small room double dry-reed pipe is normal, left side small room double dry-reed pipe fault, right small room double dry-reed pipe are normal, normal, the right small room double dry-reed pipe of left side small room double dry-reed pipe fault, left and right sides small room double dry-reed pipe fault--handle the switching signal of tongue tube input; The CC2430 data processing module is exported digital rainfall value and tongue tube operating mode, by be sent to the ZigBee telegon of the hydrology, weather station through the CC2430 radio-frequency module.
Two double dry-reed pipe output switching signals generate the mutual school algorithm flow chart of rainfall data.
The reed pipes of going alone that a double dry-reed pipe of a tipping bucket left side (or right) small room is arranged by two dislocation constitute, and and if only if detects one and go alone the reed pipe adhesive and then detect another and go alone the reed pipe adhesive, thinks that just signal is effective; Use double dry-reed pipe and above-mentioned switching signal process eliminates and gone alone the misoperation that reed pipe is subjected to the environment magnetic interference, the error of rainfall amount metering.Based on this brass tacks, not only for the treatment of the switching signal of tongue tube output, and widenable to the criterion of double dry-reed pipe operating mode: paired two to go alone reed pipe adhesive successively be nominal situation otherwise be fault condition (go alone reed pipe look it whether output switching signal is judged operating mode)--according to different operating modes, by the switching signal of different mode treatment tongue tube output; According to the tongue tube operating mode, as follows by the concrete steps of four kinds of mode treatment dry-reed tube switch signals:
1) small room double dry-reed pipe in the left and right sides is normal: the dislocation of two of left small room double dry-reed pipes is arranged goes alone reed pipe adhesive successively, a pair of switching signal of staggering the time of output, as the rainfall value of a sensibility reciprocal of rain gage; Right small room is as the same.
2) left small room double dry-reed pipe fault, right small room double dry-reed pipe are normal: the switching signal with right small room double dry-reed pipe is benchmark, reading between the group switching signal that right small room double dry-reed pipe uploads for twice (the group switching signal is gone alone the reed pipe switching signal by 2 of priority adhesive and formed), read the switching signal of left small room double dry-reed pipe, according to the operating mode of left small room double dry-reed pipe further segment, as follows by the treatment scheme of disaggregated classification:
2-1) go alone reed pipe and all can't adhesive maybe can't flick for two: data processing module is uploaded the rainfall on duty 2 of a sensibility reciprocal of right small room, shields the switching signal of left small room double dry-reed pipe, uploads the fault of left small room double dry-reed pipe.
2-2) go alone normal, another fault of reed pipe for one: the shielding fault condition go alone the reed pipe switching signal, read-only nominal situation go alone the reed pipe switching signal, data processing module is given up double dry-reed pipe, is handled (the rainfall value of a corresponding sensibility reciprocal of switching signal) by going alone the reed pipe switching signal, uploads the rainfall value of a sensibility reciprocal and the fault of left small room double dry-reed pipe.
3) normal, the right small room double dry-reed pipe of left small room double dry-reed pipe fault: with 2).
4) left and right sides small room double dry-reed pipe fault: maintain the fundamental measurement function as far as possible.
4-1) go alone reed pipe and all can't adhesive maybe can't flick for two of left and right sides small room double dry-reed pipe: upload warning.
4-2) go alone normal, another fault of reed pipe for one of left small room double dry-reed pipe, going alone reed pipe for two of right small room double dry-reed pipe all lost efficacy: the shielding fault condition go alone the reed pipe switching signal, read-only nominal situation go alone the reed pipe switching signal, data processing module is given up double dry-reed pipe, is gathered the rainfall value by going alone the reed pipe switching signal; Data processing module is uploaded the rainfall on duty 2 of a sensibility reciprocal of left small room, uploads the fault of double dry-reed pipe.
4-3) go alone normal, another fault of reed pipe for one of right small room double dry-reed pipe, go alone reed pipe for two of left small room double dry-reed pipe and all lost efficacy: same 4-2).
4-4) go alone normal, another fault of reed pipe for one of left small room double dry-reed pipe, one of right small room double dry-reed pipe goes alone that reed pipe is normal, another fault: the shielding fault condition go alone the reed pipe switching signal, read-only nominal situation go alone the reed pipe switching signal, data processing module is given up double dry-reed pipe, is gathered the rainfall value by going alone the reed pipe switching signal; Data processing module is uploaded the rainfall value of a sensibility reciprocal, uploads the fault of double dry-reed pipe.
