Abstract

The invention discloses a water level monitor. The water level monitor comprises a microprocessor, an ultrasonic transmission signal processing circuit, an ultrasonic echo signal processing circuit, an ultrasonic transducer, a temperature sensor and a digital pressure sensor, wherein the output end of the ultrasonic transmission signal processing circuit is connected with the input end of the ultrasonic transducer; the output end of the ultrasonic transducer is connected with the input end of the ultrasonic echo signal processing circuit; the output end of the ultrasonic echo signal processing circuit is connected with the input end of the ultrasonic transmission signal processing circuit. The water level monitor is capable of detecting the water level in real time by use of the digital pressure sensor and by virtue of ultrasonic measurement, and therefore, the effectiveness of the system and the accuracy of judgment are improved, a silted pipe section can be identified effectively and data support can be provided for establishing an underground drainage pipe network maintenance scheme.

Description

A kind of water level monitor
Technical field
The present invention relates to a kind of monitoring device, particularly relate to a kind of water level monitor.
Background technology
Unwatering system is urban construction, environmental protection, the important infrastructure of controlling flood and draining flooded fields; set up urban drainage pipe network water level information monitoring system; for municipal drainage supvr provides Real Time Observation drainage pipeline networks SEA LEVEL VARIATION, analyzes the management platform of drainage pipeline networks dynamic operation situation, become the pressing needs of modern city drainage management.Municipal drainage pipe just has an inspection shaft connecting ground every tens meters, if can measure the height of water level of inspection shaft in inspection shaft continuously and automatically, and data are sent to administrative center, administrative center has also just grasped the real-time change situation of water level in drainpipe.The environment held in well due to draining is very severe and can not provide power supply, traditional level sensing is established respectively as the magnetic floating liquid level gauge of contact, servo-type level meter, static pressure called putting-into-type liquid level meter etc., equal to being difficult to solve the corrosion in water in drain well, mud adheres to, easily when pipeline maintenance the harsh conditions such as impaired impact and cannot use, contactless normal ultrasound waves tank gage is then because of the intrinsic ultrasound wave angle of divergence, there is certain measurement from district, the factors such as power consumption is larger, also cannot be narrow space Di, SEA LEVEL VARIATION even can flood measurement mechanism very greatly, do not have to apply in the drain well of power supply.Owing to lacking suitable level measurement device, so far still have to regularly or as required adopt manual mode to measure and record water level by full-time staff, the operational management of drainage pipeline networks has to rest on traditional management mode due to the disappearance of real-time information, cause the real-time of information not high, affect the judgement to system situation.
Summary of the invention
It is simple that object of the present invention is just to provide a kind of cost to solve the problem, and responds water level monitor timely.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The present invention includes microprocessor, ultrasound wave sends signal processing circuit, ultrasonic echo signal treatment circuit, ultrasonic transducer, temperature sensor, digital pressure sensor, described water level monitor comprises microprocessor, ultrasound wave sends signal processing circuit, ultrasonic echo signal treatment circuit, ultrasonic transducer, temperature sensor, digital pressure sensor, the output terminal that described ultrasound wave sends signal processing circuit is connected with the input end of described ultrasonic transducer, the output terminal of described ultrasonic transducer is connected with the input end of described ultrasonic echo signal treatment circuit, the input end that output terminal and the described ultrasound wave of described ultrasonic echo signal treatment circuit send signal processing circuit is connected, the output terminal that described ultrasound wave sends signal processing circuit is connected with the input end of described micro-process, the output terminal of described temperature sensor is connected with the input end of described microprocessor, and the output terminal of described digital pressure sensor is connected with the input end of described microprocessor.
Particularly, described digital pressure sensor is arranged on the position close to ultrasonic measurement blind area.
Beneficial effect of the present invention is:
The present invention can be detected water level in real time by the mode of digital pressure sensor and ultrasonic measurement, improves the actual effect of system and the accuracy of judgement, effectively identifies alluvial pipeline section, provides Data support for formulating underdrainage pipe network maintenance plan.
Accompanying drawing explanation
Fig. 1 is system architecture schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, the present invention includes microprocessor, ultrasound wave sends signal processing circuit, ultrasonic echo signal treatment circuit, ultrasonic transducer, temperature sensor, digital pressure sensor, digital pressure sensor be arranged on position close to ultrasonic measurement blind area, described water level monitor comprises microprocessor, ultrasound wave sends signal processing circuit, ultrasonic echo signal treatment circuit, ultrasonic transducer, temperature sensor, digital pressure sensor, the output terminal that described ultrasound wave sends signal processing circuit is connected with the input end of described ultrasonic transducer, the output terminal of described ultrasonic transducer is connected with the input end of described ultrasonic echo signal treatment circuit, the input end that output terminal and the described ultrasound wave of described ultrasonic echo signal treatment circuit send signal processing circuit is connected, the output terminal that described ultrasound wave sends signal processing circuit is connected with the input end of described micro-process, the output terminal of described temperature sensor is connected with the input end of described microprocessor, the output terminal of described digital pressure sensor is connected with the input end of described microprocessor.Regional database server is installed Wireless transceiver module and intelligent encryption card.
Workflow of the present invention is as follows:
In the normal measurement range of ultrasound wave, arithmetic control circuit sends signal processing circuit by ultrasound wave and sends driving pulse energy to ultrasonic transducer, ultrasound wave is converted to water surface directional transmissions by ultrasonic transducer, ultrasound wave arrives water surface back reflection and returns ultrasonic transducer, convert electric signal to by ultrasonic transducer and deliver to arithmetic control circuit by ultrasonic echo signal treatment circuit, by arithmetic control circuit, ultrasound wave is converted into the distance of ultrasonic transducer transmission face to water from being issued to the transmission time difference received, carry out by the Intelligent treatment of software the noise data that filtering misconvergence of beams causes borehole wall interference echo to produce by arithmetic control circuit, and reject the data of irrational second trip echo generation, draw real water level numerical value, when water level rises to ultrasonic measurement blind area, the force value that arithmetic control circuit receives digital pressure sensor exports, force value is converted into the height of water level.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included in protection scope of the present invention.
