Also can in the pipe of simulation well face, place fixture, the well face of tube wall inside-fixture below is vertical moving up and down, by ultrasound wave the height of fixture is detected the precision and the accuracy that can improve the ultrasonic investigation water level, thereby calculate the water level of open river surface.
The effector can pass through wireless connector, manually initiatively obtains water level signal, convenient management.
The purpose of wireless communication link processor is regularly to send measuring command, regularly the distance signal of the output of range finder module is passed through it, sends to the information monitoring center.The wireless link processor is done pre-service to the SEA LEVEL VARIATION of burst, such as repeatedly sending little time interval measurement, in the hope of the accuracy of its measurement.When mutation of water level occurring and obtain confirming, force to send warning information to the information monitoring center.
When the wireless communication link processor sends measuring command, pass through timer, oscillator and electroacoustic transducer produce ultrasound wave, the ultrasonic investigation probe sends ultrasound wave immediately by the simulation well facial canal, when ultrasound wave runs into the well face, return the reflected back ultrasonic signal immediately, pass through acoustical-electrical transducer, device when receiving detection and machine, obtain the mistiming of needs, pass through controll block, calculate the distance of ultrasonic probe to the well face, the digital signal that obtains is outputed on display and the wireless link processor then, send to water level Centralized Monitoring center by the wireless link processor.
Simulation well face stationary pipes possesses certain rigidity, and is vertical substantially with surface level during placement, and the lower end can be solid or hollow as fixing usefulness.But on stiff end is imbedded, one or more saturating cinclides is set.
Display can be a light-emitting diode display, also can be voice guard.
This has overcome personal monitoring's mode of today, time-consuming, effort, and the response time is slow.And have automatic monitoring, unmanned, the response time is fast, applied range.
