Description of drawings
Fig. 1 is the building-block of logic of the Ultrasonic Nondestructive system of the utility model employing wireless data transmission.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
The utility model one embodiment discloses a kind of Ultrasonic Nondestructive system of employing wireless data transmission, and Fig. 1 is the building-block of logic of the Ultrasonic Nondestructive system of the utility model employing wireless data transmission, as shown in Figure 1:
This system comprises host computer and slave computer, and wherein said host computer and slave computer all are connected with a wireless data communications module respectively, carry out data transmission by the wireless data communications module between described host computer and the slave computer; Described wireless data transfer module is connected with host computer or slave computer by USB interface.
In the present embodiment, described host computer is generally industrial computer, notebook computer or desktop computer computer, main operation Ultrasonic Nondestructive software, be used to receive the command information of user's input, and the detected data of output slave computer, carry out the later stage complex process of data, with the form display defect position and the size of waveform or image; Described slave computer is generally PLC or single-chip microcomputer, is is generally manufactured and designed by system manufacturer, is used to adopt the defective of ultrasound examination measured piece inside, and major function is ultrasonic excitation, receive amplification, detection filter, AD conversion etc.
In the present embodiment, described wireless data communications module comprises rf receiver and transmitter and antenna, and wherein said antenna is built in the radio-frequency (RF) transceiver.Aspects such as the coded system of choosing main transmission performance from chip, power consumption, data transmission of the rf receiver and transmitter in the wireless data communications module, antijamming capability, Application and Development comfort level are chosen.In the present embodiment, what the rf receiver and transmitter of wireless data communications module adopted is to support the RTL8187L of IEEE802.11g procotol system as rf receiver and transmitter, and described RTL8187L rf receiver and transmitter meets the requirement of the 2.4GHz radio frequency of IEEE802.11g technology to low cost, low-power consumption, high-speed transfer.
In one embodiment of the present of invention, the principle of work of the Ultrasonic Nondestructive system of described employing wireless data transmission is as follows:
The main wireless data communications module that adopts realizes real-time Long-distance Control and data transmission in the native system, because volume of transmitted data is big, and it is very high to the accuracy requirement that carries out data transmission, antijamming capability is strong, therefore with IEEE802.11g procotol system as the wireless data transmission framework, the 2.4GHz frequency range that this agreement adopted is the open frequency range in the world, need not licensing, has reduced the complexity of test job and loaded down with trivial details.Described network can be in GPRS, EDGE, 3G or the WiFi network a kind of.
