Abstract

The invention relates to a general instrument VXI-11 protocol adaptation system, a general instrument with the system and an adaptation control method, and belongs to the technical field of general instrument remote control. The system comprises a port mapping module and a VXI-11 server module. In the control method, after the port mapping module responds to a search command of a remote control end, the remote control end establishes connection between the remote control end and the VXI-11 server module based of the fact that the port mapping module responds to the search command of the remote control end and then sends an instrument control command to the VXI-11 server module, and the VXI-11 server module sends the instrument control command to the connected general instrument and the instrument control command is executed and returns execution result data to the remote control end.. Compared with a general purpose interface bus (GPIB) interface, the general instrument VXI-11 protocol adaptation system, the general instrument and the adaptation control method are high in reliability, lower in cost, and flexible and compact in system structure, can be applied to small users, can be applied to a complex user, and satisfy needs for scientific research and development, production and the like.

Description

technical field

[0001] The invention relates to the technical field of remote control of general instruments, in particular to the technical field of VXI-11 protocol adaptation of general instruments, and specifically refers to a general instrument VXI-11 protocol adaptation system, a general instrument and an adaptation control method. Background technique

[0002] In order to use a general-purpose instrument for automated testing, it is necessary to remotely control the instrument. At present, the more common method is the GPIB (General Interface Bus) interface. GPIB is a bus specially designed for instrument control applications. It has high stability and high reliability. Due to its low delay and acceptable bandwidth, GPIB is still a common choice in instrument control. The advantage of GPIB is that it can provide Widely adopted in the industry, but the price of GPIB interface cards and cables is very high, the transmission speed is slow, limited by the control node, and...

Embodiment Construction

[0032] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0033] see figure 1 As shown, it is a connection relationship diagram between the general instrument VXI-11 protocol adaptation system and the general instrument remote test system of the present invention.

[0034] In one embodiment, the general instrument VXI-11 protocol adaptation system includes: a port mapping module, a VXI-11 server module and a plurality of network ports. Wherein, a plurality of network ports are connected to the remote control terminal through a local area network; the port mapping module is used to map the plurality of network ports, and maintains the registered program number and port correspondence table; the VXI-11 server module monitors a network port and sends The port mapping module registers the used network port and program number, and this port number is used to establish a connection with the remote contro...
