Embodiment
Explain further details in the face of the utility model down.
Please consult Fig. 1 simultaneously, it is the theory diagram of the utility model based on the PXI platform testing system.Said test macro based on the PXI platform comprises interconnective control system 1, PXI platform 3 and adapter 4 and the power supply 2 that is used to supply power.Said adapter 4 has from fitting other circuit, and this self-identifying circuit comprises adaptor power supplies 7, microprocessor 8, storer 10, bus circuit, serial converter 6 and serial ports 5.Wherein, adaptor power supplies, storer and bus circuit all are connected on the microprocessor, and bus circuit is connected on the control system behind converter and serial ports.Said bus circuit is the RS485 circuit, and said serial ports is the RS232 serial ports, and said converter is a RS485 RS 232 converter.Said storer is erasable formula storer.
The utility model adopts sequence number chip identification circuit, in adapter, utilizes the information of memory chip stores to carry out adapter identification.Add storer (EEPROM) with the microprocessor minimum system and be the main body, obtain the ID sign indicating number of EEPROM through microprocessor, as Adapter ID.With RS485 RS 232 converter is connection, realizes that slave computer and host computer carry out exchanges data, carry out judgment processing with upper computer software.If corresponding mistake is not pointed out to meeting in the address, tell operating personnel to change correct adapter.So both can guarantee the stable operation of equipment, dirigibility, reliability are all very high.
See also Fig. 2, it is the self-identifying process flow diagram of the utility model based on the test macro of PXI platform.The self-identifying principle of work of the utility model PXI system platform adapter is: all distribute a unique ID respectively for each adapter, this ID can be an analog quantity, also can be digital quantity.If the ID during test in the ID of adapter and the host computer corresponding software is corresponding, think that adapter installs correct otherwise the prompting mistake.ID is provided by the self-identifying circuit of adapter, in adapter, adds identification circuit, is used for identifying different adapters.Concrete identifying is that host computer procedure sends information through the port of reserving, and is sent to slave computer, and feedback adaptation device ID gives host computer if slave computer is worked.Judge whether to be selected adapter by host computer.If then open the corresponding software of corresponding adapter, otherwise prompting adapter mistake or fault require the staff to change correct adapter and perhaps keep in repair existing equipment.
The utility model is through the use of self-identifying circuit in sum; Improve the intelligent level of testing apparatus, strengthened the reliability of equipment, effectively prevented the unnecessary loss that human error causes; Promote PXI system platform test mass and work efficiency, shortened the test duration.
