Reach highest efficiency.Receiving portion uses high-sensitivity ultrasonic probe, and is filtered, and improves, at multistage amplification
Reason is sent into extraction circuit and carries out flight time counting.
Multi channel signals scheduling problem solution：The method that single channel ultrasonic wave measures has been widely used, mostly logical
Road ultrasonic wave measuring method at present it is scarce seldom because this technology be not it is simple it is single pass enumerate, there is more
Channel signal is dispatched and algorithmic issue, and in the design, each channel exclusively enjoys a signal-processing board 6.2-6.5, specifically which
Label channels operation is operated in which kind of mode is scheduled by master control borad 6.1, data that master control borad 6.1 gets that treated
Modeling progress operation is substituted into afterwards and obtains last result of calculation, and is stored.
Obtain cross-sectional area solution to the problem：In order to more accurately obtain the cross-sectional area of measured medium, the design
The middle ultrasonic probe support using standard geometrical shapes, and visited using water-level gauge 17, pressure sensing cell 11 and ultrasonic wave
First 15 3 kinds of measurement methods cooperative height of water level, to obtain relatively accurate cross-sectional area.

Door switch controls：When debugging and maintenance personnel need to carry out debugging maintenance to equipment in control cabinet 6, pass through mobile phone
APP softwares propose application of unpacking to monitor supervision platform, and by application, monitor supervision platform Remote Open electronic lock, chamber door flicks.Debugging and
At the end of maintenance, debugging is proposed by cell phone application, safeguards and terminates application, platform remotely closes chamber door by wireless network.
Self-destruction controls：Chamber door electronic lock can detect whether to open chamber door by force, and 5 faces all carry broken meeting in addition to chamber door in case
Capacitor board is detected, program enters self-destruction interruption, and delay detection opens chamber door condition by force if met, equipment report and alarm, and
Prompt closes chamber door in 10 seconds, if still thrusted oneself in, host CPU and digital signal panel CPU programs will be wiped voluntarily, and
The external memory power supply for opening high pressure access FPGA burns external memory.If detection is to open babinet from non-chamber door, if
Standby report and alarm information, does not prompt, and directly carries out self-destruction program, the safety for ensureing device software intellectual property.
Channel switching control：As shown in fig. 6, after device power completes initialization, whether detection measurement pattern is automatic mold
Formula, if it is automatic mode, equipment needs which channel of self judgment that can open simultaneously, then direct if it is manual mode
By looking for the sequence of user setting to carry out Channel scan, the foundation of judgement is to open the transmitting in a channel, open all channels
It receives, to judge to emit the area coverage of ultrasonic wave, a channel emission can be received simultaneously and carry out the receiving channel of signal not
It can open simultaneously.Master control borad 6.1 obtains the sequence of channel switching control by the test result analysis to each channel.
The specific implementation mode of the present invention is described above, but the present invention is not limited to above description.For this
For the technical staff in field, any equal modification and replacement to the technical program is all within the scope of the invention.Cause
This, without departing from the spirit and scope of the invention made by impartial conversion and modification, all should be contained within the scope of the invention.
