Abstract
Strain measurement system in the prior art has that sampling precision is not high, group bridge form is inflexible, transmission range is short, communication modes are single, people's circle interactive mode is inflexible.In view of the defect of the prior art, the invention proposes a kind of program-controlled strain measurement system of sound state, using 24 A/D chips, the precision of the sampling of the raising of high degree, each measuring point arbitrarily organize bridge, improve a group flexibility for bridge form, it is integrated with network interface, USB, RS485, WIFI, the communication modes such as ZIGBEE, substantially increase the ability to communicate of system, and man-machine interface uses touch LCD color screen, user can input parameter in liquid crystal color screen, observe the information of sampling.
Description
Technical field
The invention is related to strain testing field more particularly to a kind of program-controlled strain measurement system of sound state.
Background technique
That there are sampling precisions is not high for strain measurement system in the prior art, group bridge form is inflexible, transmission range is short,
The problem that communication modes are single, people's circle interactive mode is inflexible.
Summary of the invention
In view of the defect of the prior art, the invention proposes a kind of program-controlled strain measurement system of sound state, uses 24
The A/D chip of position, the precision of the sampling of the raising of high degree, each measuring point arbitrarily organize bridge, improve the flexible of group bridge form
Property, it is integrated with network interface, USB, RS485, the communication modes such as WIFI, ZIGBEE substantially increase the ability to communicate of system, man-machine boundary
Face uses touch LCD color screen, and user can input parameter in liquid crystal color screen, observe the information of sampling.
The invention technical problems to be solved:
The invention uses the form of FPGA+ARM combination, and the data between FPGA and ARM need ceaselessly to swap, first
First to solve the Communication of FPGA and ARM.
The solution that the invention uses:
The program-controlled strain measurement system of sound state includes ARM and FPGA, is communicated between ARM and FPGA by FSMC.
The ARM connection touch screen, RS485, network interface, WiFi, Zigbee, SD card, the FPGA connection relay,
A/D conversion, D/A conversion, calibration, alarm, analog signal conditioner.
Connect electric bridge under the relay.
The utility model has the advantages that
FSMC communication modes are flexible, and after program parameter configures, address wire and data line are according to configuration parameter automatic running.
After FPGA and ARM communication, FPGA can individually control each road and bridge paths, solve ARM chip pin not
The problem of foot.
FPGA and ARM division of labor work, FPGA are controlled, and ARM is communicated, and circuit system combination is more rationally perfect.
Detailed description of the invention:
Fig. 1 is the schematic diagram of the invention.
Specific embodiment:
1 pair of the invention is further elaborated with reference to the accompanying drawing:
The form that the invention is combined using FPGA and ARM, the resource of ARM is fully utilized, if independent with ARM
It is CPU, touch screen, network interface, wifi, zigbee, SD card, AD, DA etc. can occupy a large amount of I/O pin, then remaining I/O port
Analog switch or latch, which must be cooperated, just can carry out the switching of bridge, and existing FPGA and ARM shares out the work and help one another, between use
FSMC carries out the exchange of data, and respective I/O port all obtained sufficient use so that the invention have it is quite perfect
Function, this is also that existing strain system does not have.
