Have long -range online maintenance and upgrading function. From taking air pressure compensation, eliminate atmospheric pressure and change the measuring error who causes for measuring result is truer, and measurement accuracy is higher.
Description
Technical field
The utility model relates to water-level gauge technical field, is specially a kind of band atmospheric pressure compensating integral type underground waterPosition meter.
Background technology
The resource that China owner is wide, is a mass of numerous rivers and lake, is having equally wideMarine resources and groundwater resources, hydrologic monitoring is an important job, the simultaneously prison to level of ground waterSurvey the work that is also absolutely necessary, so that understand level of ground water situation, be convenient to understand the change of level of ground waterChange, thereby can better remove rationally to utilize groundwater resources, simultaneously also can be better to underground waterResource is better protected, and will use like this water-level gauge, and the utilization of water-level gauge makes underground waterThe exploration of position is more convenient.
Existing product is generally only with liquid level sensor, in measuring, it has been generally acknowledged that atmospheric pressure is oneFixed value (standard atmospheric pressure), but in actual use procedure, in the region of different weather and height above sea level,The variation of atmospheric pressure is very large, surveys factually, and in ground floor, highly every liter of 100m, air pressure is flatAll reduce 12.7hPa, be less than this numerical value at high level. According to standard atmospheric pressure 1013hpa estimation, oneIndividual standard atmospheric pressure approach 10.3m hydraulic pressure (P=ρ gh, the density of water is 10^3kg/m^3,G=9.8N/kg), as height above sea level rising 100m, atmospheric pressure approaches 1000hpa left and right, and atmospheric pressure only has10.2m hydraulic pressure (P=ρ gh, the density of water is 10^3kg/m^3, g=9.8N/kg), visible altitude change100 meters, measure error reaches 0.1m=10cm. Considerably beyond the measurement mistake of general liquid level sensorPoor, the variation of atmospheric pressure be can not ignore, and will make water if ignored the variation of atmospheric pressureThe accuracy that position is measured declines greatly, and these are problems that we need to face, and is also to need that we goThe problem solving, thus go to improve convenience and the accuracy of underground water level measurement.
Utility model content
The purpose of this utility model is to provide a kind of band atmospheric pressure compensating integral type underground level gauge, to solveThe problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of band atmospheric pressure compensating oneFormula underground level gauge, comprises CPU and sensor acquisition and conditioning circuit, described CPU input and sensorAcquisition and conditioning circuit output is electrically connected, and described sensor acquisition and conditioning circuit output is electrically connected withBaroceptor and liquid level sensor, described CPU input end signal is connected with lithium battery power supply and power supply pipeReason module, described CPU output end signal is connected with solid-state memory.
Preferably, described CPU output also signal be connected with GPRS/CDMA module and RS232/RS485Interface.
Compared with prior art, the beneficial effects of the utility model are: the utlity model has atmospheric pressure compensatingFunction, has reduced measure error, and sensor carries temperature-compensating, makes certainty of measurement higher, power supply pipeReason module, can control modules power supply, and power supply when module work, closes power down while workSource, the power consumption of the product reducing greatly. Having remote online safeguards and upgrade function. Carrying air pressure mendsRepay, eliminate the measure error that air pressure change causes, make measurement result truer, certainty of measurement moreHigh.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technology in the utility model embodimentScheme is clearly and completely described, and obviously, described embodiment is only one of the utility modelDivide embodiment, instead of whole embodiment. Based on the embodiment in the utility model, this area is commonTechnical staff is not making the every other embodiment obtaining under creative work prerequisite, all belongs to thisThe scope of utility model protection.
Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of band atmospheric pressure compensating integrallyLower water-level gauge, comprises CPU and sensor acquisition and conditioning circuit, described CPU input and sensor collectionModulate circuit output is electrically connected, and described sensor acquisition and conditioning circuit output is electrically connected with air pressureSensor and liquid level sensor, described CPU input end signal is connected with lithium battery power supply and power management mouldPiece, described CPU output end signal is connected with solid-state memory. Described CPU output also signal is connected withGPRS/CDMA module and RS232/RS485 interface.
Concrete, when use, being provided with baroceptor, the pressure of establishing liquid level sensor measurement is P1,The pressure that baroceptor is measured is P2, actual liquid pressure P=P1-P2, then according to P=ρ gh,Can be regarded as out liquid actual height, in passing product, P2 is defaulted as to standard atmospheric pressure (fixingValue) way, the method is avoided the impact of change of atmospheric pressure on level gauging. Sensor carries temperature and mendsRepay, make certainty of measurement higher, lithium battery power supply and power management module, can enter modules power supplyRow is controlled, and power supply when module work, turns off power supply while work, the power consumption of the product reducing greatly.The system that is arranged so that of GPRS/CDMA module and RS232/RS485 interface has remote online maintenance simultaneouslyAnd upgrade function.
The utlity model has atmospheric pressure compensating function, reduced measure error, sensor carries temperature and mendsRepay, make certainty of measurement higher, power management module, can control to modules power supply moduleWhen work, power, while work, turn off power supply, the power consumption of the product reducing greatly. There is remote onlineSafeguard and upgrade function. Carry atmospheric pressure compensating, eliminate the measure error that air pressure change causes, make to measureResult is truer, and certainty of measurement is higher.
Although illustrated and described embodiment of the present utility model, for the ordinary skill people of this areaMember, being appreciated that can be real to these in the situation that not departing from principle of the present utility model and spiritExecute example and carry out multiple variation, amendment, replacement and modification, scope of the present utility model is by claimsAnd equivalent limits.
