Description
Technical field
The invention belongs to tipping-bucket rain-gauge technology category, refer to especially base oneself upon the framework of existing single tilting bucket rain, technology and the method that improvement rain gage measuring accuracy improves reliability.
Background technology
Rainfall amount is the fundamental of the hydrology, meteorology, and its measured value all has important directive significance to industrial and agricultural production, flood control mitigation etc.China's gross amount of water resources 28,124 hundred million m
3, occupy the 5th in the world; Have per capita 2163 m
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 domestic siphon rainfall recorder that automatically detects rainfall amount comes out, and replaces rapidly traditional artificial rain gage and is used widely; But siphon rainfall recorder needs could to obtain through converting the robotization requirement that rainfall intensity, analog quantity recording mode are not suitable with the hydrology, weather information, and measuring accuracy has much room for improvement in addition.Nineteen eighty-three, hydrological instrument factory in Chongqing releases First 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: such 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 the requirement of environment, power supply, measuring accuracy, the total cost of ownership (TCO) etc.), there is no the leading position that method is shaken tipping-bucket rain-gauge.
Tipping-bucket rain-gauge is comprised of skip bucket rainfall sensor and data acquisition process transmission unit two parts, and the data acquisition process transmission unit is called for short number and adopts the unit.Under the prior art condition, number is adopted comparatively degree of ripeness of monotechnics, can satisfy the requirement of rainfall observation; Problem is that the error in dipping of skip bucket rainfall sensor is larger.The sensor of tipping-bucket rain-gauge is a tipping bucket type mechanical bistable Weighing mechanism--the triangular shaped container (small room) of two full symmetrics that the employing central dividing plate separates, central dividing plate can rotate, be similar to around transverse axis the principle of seesaw, and is also quite perfect through the constantly overall architecture perfect, the tipping bucket type sensor in 30 years; Rainwater flows on the process nature of tipping bucket, and to be sensor carry out the process of integration to the raininess signal by certain area, and integrated value is exactly the capacity of tipping bucket, also claims the resolution of rain sensor.Rainwater injects the left small room of tipping bucket, when connecing rainwater volume reaches predetermined value, by the left small room of gravity at t
1Constantly overturning, and from the water receiving state to the waiting status transition, right small room is then from waiting status to the water receiving status transition; t
2Rainwater injects right small room constantly, when the water receiving amount reaches predetermined value, and right small room overturning, right small room enters the transition that returns to waiting status from the water receiving state, and left small room is 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.
Tilting bucket rain is in the long-term use procedure of the hydrology, weather station, because the inherent limitation of measuring principle and instrument structure aspect fully exposes design defect.At first, measuring error changes with raininess: being overgauge and deviate during heavy showers increases with the enhancing of rainfall intensity; Be minus deviation during weak rainfall, in light rain arid area minus deviation even up to more than 10% frequently.Secondly, rainfall measurement practice for many years shows: because the sensor device of posting a letter is the fault of tongue tube, belong to than small probability event though the rainfall amount data that cause lack to survey, consequence is catastrophic often; In the face of the magnetic interference of environment, also there is the misoperation phenomenon in tongue tube, thereby produces the error in dipping of rainfall amount.The flaw of tilting bucket rain has directly affected the quality of measurement data.

Embodiment
As shown in Figure 1, single tilting bucket rain comprises skip bucket rainfall sensor and signal acquisition process communication unit (be called for short number and adopt the unit) two parts; Single tilting bucket rain sensor is comprised of the influent hopper 7 that connects down water pipe, 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.The water outlet that left and right two small rooms of tipping bucket 4 are in the influent hopper rising pipe is in turn accepted rainwater, weighs, is measured: 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 until the amount of rainfall of right small room reaches the design sensibility reciprocal, 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.
Such 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 consist of; 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 minimum solid material of surface energy, 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 next time error of rainfall amount.The alloy in lightweight material is made udometric tipping bucket, and the tipping bucket quality only has about 1/3 of conventional stainless steel; Take JDZ-1 type list tilting bucket rain as example, 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·
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;
Increase in inverse ratio, then the state of tipping bucket type mechanical bistable Weighing mechanism is changed △ t consuming time and is reduced, in the state conversion process rainfall Δ W of many meters reduce (discussion 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 poor system of rain gage damper 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, model WDF006M; Valve opening and closing device 1 be one with the mechanical linkage Ji Ju of spring, when the tipping bucket overturning, tipping bucket utilizes the weight driving mechanical Lian Gan Ji Ju valve-off of self; Turn over φ angle (angle that tipping bucket type bistable state Weighing mechanism small room state conversion time △ t turns over) after the tipping bucket overturning, the valve opening and closing device is because of the recovery characteristic of spring Open valve again again; Be temporarily stored in rainwater, the follow-up rainwater of accepting in the influent hopper in the △ t time, gather another small room of importing until the amount of rainfall of this small room reaches the design sensibility reciprocal, reappear the overturning process of first small room; Go round and begin again.When valve opening and closing device and micro valve normal operation, 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 the poor function of valve damper this moment will make measuring accuracy descend, 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 module that the unit comprises two double dry-reed pipes; The sidewall of the left small room of tipping bucket 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; The first switch output signal of going alone reed pipe is isolated U through photoelectricity in the double dry-reed pipe
