Description

Nonmetal ultrasound measuring instrument

Technical field

The utility model relates to a kind of nonmetal ultrasound measuring instrument.

Background technology

Non-Destructive Testing role in building trade is more and more important; Mainly accomplish such as concrete intensity detection and defects detection through Non-Destructive Testing; Nonmetal ultrasound measuring instrument can be under the situation of not damaging existing building or member; Detect concrete intensity and defective, can also detect the penetration of fracture of buildings in some specific occasions.

At present, nonmetal ultrasound measuring instrument both domestic and external generally adopts industry control core board, CPLD, SRAM, high-pressure modular, mimic channel, LCD to show and the button controlling schemes.Industry control core board great majority are bought from the third party; Core board sends instructions to CPLD in the sampling process; CPLD control high-pressure modular and mimic channel amplify the ultrasonic signal that receives then, again through depositing among the SRAM after the AD conversion; Core board reads the data of storing among the SRAM again through CPLD, shows through analyzing and processing again.Because industry control core board volume, cost height and power consumption are bigger; Add CPLD and SRAM circuit, make that the area of whole PCB circuit board is bigger, big power consumption will dispose big lithium battery; So the volume of total system is not very convenient with regard to being difficult to miniaturization, carrying in the work.

Summary of the invention

The purpose of the utility model provides a kind of nonmetal ultrasound measuring instrument, solve to practice thrift board area, reduces the technical matterss such as power consumption and cost of system simultaneously.

In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:

A kind of nonmetal ultrasound measuring instrument comprises arm processor, power management module and peripheral circuit; Peripheral circuit comprises the on-site programmable gate array FPGA circuit that is connected with arm processor and accepts to start measuring command, be connected on transmitting control signal of FPGA circuit starts reception amplification and the ADC change-over circuit between high pressure transponder pulse end and the FGPA inside circuit SRAM, the high pressure transmitter module that is connected with the FGPA circuit; Said peripheral circuit also comprises LCD liquid crystal display, touch-screen, button input, USB interface and the speech interface that is connected respectively with arm processor.

The utility model has the advantages that: adopt arm processor to add the FPGA scheme and can practice thrift board area greatly, the power consumption of simultaneity factor also reduces a lot, and speed is fast, and cost is also very low; FPGA has fast, high capacity, and the characteristics that extendability is strong adopt the utility model design proposal can realize the overlength working time, and its low price has the characteristics of portable miniaturization.

Description of drawings

Fig. 1 is the schematic block circuit diagram of the utility model.

Embodiment

The circuit structure of the utility model is referring to Fig. 1, mainly comprises arm processor, FPGA, mimic channel, high-pressure modular, LCD liquid crystal and by circuit such as key control.

Adopt ARM as core processor, peripheral circuit comprises FPGA, receives and amplifies, ADC conversion, high pressure transmitter module, LCD liquid crystal display, touch-screen, button input, USB interface, speech interface, power management module etc.

The flow process of ultrasonic measurement is following: ARM handles to send and starts measuring command to FPGA, and FPGA transmits control signal and starts the high pressure transponder pulse, and adjustment simultaneously receives enlargement factor; Carry out ADC conversion then, reading of data in the FGPA internal SRAM, wait measure bag data after; FPGA is provided with complement mark; Arm processor reads the SRAM data then, carries out analyzing and processing again, at last the waveform that receives is shown on the LCD liquid crystal.But the waveform that system's storage of collected arrives, then through USB interface with data conversion storage to USB flash disk, can copy on any PC through USB flash disk, analyze operations such as printing reports then with ultrasonic special software.

System is when measurement or analyzing and processing, and system can carry out the relevant voice prompting, realizes better man-machine interface operation.

The utlity model has sound prompt function and touch-input function.
