specific Embodiment approach 1

[0024] Specific implementation mode one: the following combination Figure 1 to Figure 2 Describe this embodiment, the local area network reset mechanism of this embodiment based on LXI bus standard comprises LAN reset button 1, FPGA2, embedded processor 3 and LAN status indicator 4, the output end of LAN reset button 1 links to each other with the input end of FPGA2, The interrupt signal output end of FPGA2 is connected with the external interrupt input end of embedded processor 3; the GPIO output end of embedded processor 3 is connected with the state signal input end of FPGA2, and the state signal output end of FPGA2 is connected with the LAN state indicator 4 connected to the status signal input,

[0025] When FPGA2 detects the pressing information of LAN reset button 1, it starts the reset process, and the reset process is as follows:

[0026] Step 1, the state indication of the LAN state indicator 4 remains as the state before pressing,

[0027] Step 2. Determine wheth...

specific Embodiment approach 2

[0046]Specific Embodiment 2: This embodiment differs from Embodiment 1 in that 1.2s>t1>0.8s, 4.2s>t2>3.5s, and the others are the same as Embodiment 1.

specific Embodiment approach 3

[0047] Embodiment 3: This embodiment differs from Embodiment 1 in that t1 = 1s, t2 = 4s, and others are the same as Embodiment 1.

[0048] This embodiment provides a specific example, t1=1s, t2=4s, when the instrument is powered on, if the LAN reset button is not pressed, it will keep this state, if it is pressed, FPGA2 will start counting internally, At this time, the LAN status indicator 4 remains in the state before being pressed; if the LAN reset button 1 is pressed for less than 1 second and then let go, the FPGA2 will give up the original count, and the LAN status indicator 4 still maintains the state before being pressed; if If the LAN reset button 1 is pressed for a duration greater than or equal to 1s, the FPGA2 will set the indicator light of the LAN status indicator 4 to go out and continue counting; if the LAN reset button 1 is pressed for a duration greater than or equal to 1s, but not exceeding 4s Open, then FPGA2 sends an interrupt request to embedded processor ...

Abstract

The invention relates to a network configuration and restoration method of an LXI device, belonging to the field of automatic testing and aiming to solve the problem that an LAN restoration mechanism only chooses to restore to factory setting status and works inefficiently. In the invention, on the basis of not breaching LXI norms, expanded designing is carried out on the LAN restoration mechanism of the LXI device. In the invention, time duration of manually pressing the LAN restoration mechanism is judged; and according to the time duration, different network parameters are employed to carry out LAN configuration on the LXI device and reboot an LCI program; in addition, an LAN indicator of the LXI device is employed to the status of the LAN restoration mechanism being pressed. With the method of the invention, flexibility of the LXI device in practical application is enhanced, more conveniences are provided to users; as a result, the method can be applied to designs of various LXI devices and enjoys excellent compatibility.

Description

technical field [0001] The invention relates to a network configuration reset method of LXI equipment, which belongs to the field of automatic testing. Background technique [0002] LXI (LAN eXtensions for Instrumentation) is an organic combination of computer technology, network technology and instrument technology. LXI is a new generation of network-based instrument standards suitable for automatic test system development following GPIB, VXI, and PXI instrument buses. The LXI module itself already has its own processor, LAN connection, power supply and trigger input. see figure 1 As shown, the local area network LAN reset mechanism in the existing LXI equipment includes a LAN reset button 1, FPGA2, embedded processor 3 and LAN status indicator 4, and the LAN reset mechanism is a manual recovery mechanism provided by the LXI equipment for the user. Recovers a device incapable of normal LAN communication from a non-configured LAN setup state. This mechanism is very neces...
