Embodiment
As shown in Figure 1, the utility model polycore cable checkout equipment comprises host computer 1 and slave computer 2.
Program in described host computer 1 uses VC programming realization, can the test case of Real-time Collection and display multi-coaxial cable assembly, can preserve data as required simultaneously, be convenient to subsequent treatment and analysis.
Described slave computer 2 comprises three single-chip microcomputers 22, usb bus connect chip 24, power supply chip 26, RC circuit 28, and cable socket 29.A slice in described three single-chip microcomputers 22 is as main frame, and all the other two panels are as from machine.Single-chip microcomputer 22 as main frame is connected with host computer 1 by usb bus connect chip 24, realizes the communication between host computer 1 and slave computer 2, is connected on the single-chip microcomputer 22 as main frame as the two panels single-chip microcomputer 22 from machine.The I/O interface of three single-chip microcomputers 22 is many, can detect break-make and the short trouble of multi-coaxial cable assembly, uses patchcord can test various types of cable assembly.I/O interface on single-chip microcomputer 22 is connected with the cable socket 29 on circuit board.
Optimize, in order to prevent electrostatic interference and the excessive damage causing single-chip microcomputer 22 of immediate current, connecting RC circuit 28 at the I/O interface of single-chip microcomputer 22 and protecting single-chip microcomputer 22.
Described single-chip microcomputer model is MSP430F5438A, and described usb bus connect chip 24 model is CH341, and described power supply chip 26 model is MIC29150-3.3BT.
Each MSP430F5438A single-chip microcomputer has four common serial communication interface (USCI) modules, adopts UART communication pattern, and outside the I/O interface that removing single chip communication and normally working occupies, the operational I/O interface of slave computer 2 reaches individual more than 200.CH341 is the connect chip of a usb bus, can simulation standard serial ports, and the USB interface of host computer provides the power supply of 5V500mA, through the power supply that chip MIC29150-3.3BT changes 3.3V into, powers to lower computer system.
Whole circuit structure is fairly simple, and input/output interface is many.Needing the cable assembly detected to be inserted on the cable socket of slave computer 2, host computer 1 sends instruction and detects, and the cable under test assembly of other types can use Splices cable line.
