Description
Affiliated technical field:
The present invention relates to a kind of channel or river course with ultrasonic flow sensor array and method for arranging thereof, utilize ultrasonic detection technology to come the metering liquid flow, belong to acoustics, sensor technical field.
Background technology:
At present, be applied to the ultrasonic flow meter of river course and channel, employing be ac power supply method; Sensor is installed the mode of the whole cross section installation of adopting river course or channel; Exist following problem: 1, the infield of AC power can not be provided, can not install and use, 2, receive the restriction of on-the-spot mounting condition more; On-the-spot installation difficulty is big, and installation accuracy is difficult for guaranteeing.3, need formulate different mount schemes according to on-site actual situations.
Summary of the invention:
The object of the invention provides a kind of channel or river course with ultrasonic flow sensor array and method for arranging thereof, and simple installation, applied widely, workable solves the problems referred to above that exist in the background technology.
Technical scheme of the present invention is:
Ultrasonic flow sensor array is used in a kind of channel or river course; Comprise the array framework that is arranged on channel or the river course and many to sensor; The array framework is made up of many root posts, and a plurality of sensors are set on every root post, and two adjacent upright posts become one group of column; Constitute a sound travel detection arrays; The corresponding one by one coupling of sensor on two columns of sound travel detection arrays is organized column more and is arranged on channel or the river course, and many on a plurality of sound travel detection arrays become array structure to sensor cloth in channel or river course.
Sensor on each group column is provided with a sensor controller and manages; A plurality of sensor controllers are through wired or wireless connected mode connection traffic integrating instrument; The data of sensor are sent to flow integrator; By flow integrator data on flows is shown again, accomplish whole measurement.
A kind of channel or river course are provided with the array framework with the method for arranging of ultrasonic flow sensor array on channel or river course, the array framework is made up of many root posts; A plurality of sensors are set on every root post; Two adjacent upright posts become one group of column, constitute a sound travel detection arrays, the corresponding one by one coupling of the sensor on two columns of sound travel detection arrays; Many group columns are arranged on channel or the river course, and many on a plurality of sound travel detection arrays become array structure to sensor cloth in channel or river course.
Sensor on each group column constitutes a sound travel detection arrays; Use many ultrasonic flow sensors, form a plurality of sound travel detection arrays, a plurality of such sound travel detection arrays are pressed regular fashion install powered battery or Alternating Current Power Supply; Be fixed on the mounting bracket; This mounting bracket is fixedly mounted on canal or the river course, so just on needs carry out canal or the river course of flow detection, sets up a flow detection matrix, thereby the detection section in canal or river course is carried out omnibearing detection.
Each flow sensor sound travel detection arrays is managed by a sensor controller; A plurality of sensor controllers can be through wired or wireless connected mode; The data of sensor are sent to flow integrator, by flow integrator data on flows are shown again, accomplish whole measurement.
The logarithm of said flow sensor is restriction not, and in the single array, just a sound travel detection arrays can be four pairs, eight pairs even more, and installation method also is not limited to vertical installation, also can have angle to install.The support that flow sensor is installed array can design based on the actual conditions at scene, adopts the easiest installation method, during on-the-spot installation, even can the asymmetric installation in the left and right sides, installation method is very flexible.
A plurality of sensor sound travel detection arrays in the inventive method; When one or more sensor sound travel detection arrays goes wrong; When quitting work, as long as there is a sensor sound travel detection arrays to work, even only surplus pair of sensors can be worked under the opposite extreme situations; Flow instrument can be worked equally, but flow accuracy can receive certain influence.And the sensor installation and application of mentioning in the background technology if there is pair of sensors to go wrong, promptly can influence the measuring accuracy of flow instrument, and needs to proofread and correct again when repairing, and is very complicated time-consuming.
The present invention is with separate survey sensor in the every pair of survey sensor in the prior art; Change an one-piece construction of fixed position relation into; Can in flow sensor sound travel detection arrays, arrange one or more pairs of flow sensors, arrange that according to the measurement of correlation standard-required each is to survey sensor.Only the sensor array framework that the flow sensor array is installed, overall fixed gets final product on river course or channel, need not loaded down with trivial details installation process during installation, and this also is the fundamental difference place of the present invention and existing canal or river course mounting arrangements method.
Beneficial effect of the present invention: compare with the prior art scheme, installation process of the present invention is convenient and swift, because in the factory process process; Stationkeeping with sensor is installed on the sensor array support; The on-the-spot installation do not require very high installation accuracy, thereby simplifies installation process greatly, saves the set-up time; Guarantee the instrument measurement precision, also widened the fitting limit of sensor simultaneously; That the present invention has is rational in infrastructure, technology is advanced, characteristics such as easy for installation, applied widely, can be widely used in the measuring technique in channel or river course.
