Background technology

Sound surface filtering device is as a kind of electronic component, be widely used in communication technical fields such as television system, satellite communication, mobile communication, radio-paging, computer and warning system, fast development along with the communication technology, the market demand of acoustic surface wave filter device is bigger, purposes is wider, kind and specifications and models are also more and more, and are higher to its technical quality requirement.

Defectives such as the measuring accuracy that manual testing's sorting exists is not high in order to overcome, poor reliability and operating efficiency are lower, the patent of invention of number of patent application 200810203550.8, a kind of acoustic surface wave filter device Auto-Test System is provided, has connected and composed by test fixture, Network Analyzer, GPIB-PCI change-over circuit, computer, man-machine interface, I/O interface circuit.Device inserts test fixture, the parameter of gathering is by the gpib interface output of Network Analyzer, read in computer through the GPIB-PCI change-over circuit, finish the test of device by the algorithm of built-in computer, output at last is store test results also, and last computer is finished the output of stepping signal automatically by the I/O interface circuit.

But the resource utilization and the cost performance of Auto-Test System are low, function relatively a little less than, equipment cost is higher, has increased production cost; Simultaneously, at the more situation of the model of present sound surface filtering device, as simultaneously the sound surface filtering device of multiple different model being carried out sorting because of producing needs, also there is ineffective defective in the Auto-Test System of above-mentioned single station.

The utility model content

The purpose of this utility model is at above-mentioned defective of the prior art, proposes a kind of multistation sound surface filtering device testing, sorting control system that can carry out multiple model device detection simultaneously, enhance productivity and reduce production costs.

The technical scheme that realizes above-mentioned purpose is as follows:

A kind of multistation sound surface filtering device testing, sorting control system comprises that test fixture, test amplifier are connected in series assembly with the order of Network Analyzer, and described serial connection assembly is 2 covers;

The Network Analyzer of described serial connection assembly links to each other with the input end and computer that contains test control software by 1 GPIB card;

Described computer input/output terminal is by 1 block I/O card connection input/output signal conditioner, and described input/output signal conditioner is connected with station test starting interface circuit, station test result display, the automatic sorting control interface of station circuit respectively;

Described station test starting interface circuit, station test result display, the automatic sorting control interface of station circuit are all identical with the tricks of described serial connection assembly.

Further, also comprise 1 cover or 2 cover serial connection assemblies, the Network Analyzer of described serial connection assembly links to each other with described input end and computer by other 1 GPIB card again.

According to above-mentioned technical scheme, testing, sorting control system of the present utility model can connect Network Analyzer 2～4 covers that have the GBIP interface simultaneously, tests simultaneously for 2～4 stations; 2～4 stations can be distinguished the filtering device of testing 2～4 kinds of models simultaneously, mutually noninterfere.

Each test station can be according to user's management expectancy, by parameters such as computer input job number, class number, Part No., asset number, test indexs, can inquire about the statistical information of detection data on duty, as detecting element quantity on duty, qualified and defective number of elements etc.

Wherein, can be respectively by the test parameter of 2～4 stations of four layout setting on the computer, the project of test parameter comprises: centre frequency, insert loss, passband fluctuation, group delay, group delay fluctuation, stopband loss, bandwidth, waviness, particular point group delay, particular point decay and time domain, have each parameter testing scope is provided with function with classification.

2～4 station test result displays can on each station, show respectively Grade A, goods of inferior quality, third grade product, waste product etc. the state of test result, and the duty of corresponding station.

Test result can also connect the internet by network interface simultaneously, calls for enterprise management level.

With respect to prior art, the beneficial effects of the utility model are:

1, can make up sound surface filtering device testing, sorting control system according to production requirement, adjust the station number arbitrarily, whole system only adopts a cover computer system, two GBIP cards, a block I/O card (wanting whole 2～4 covers originally), guaranteed that the test speed operation is normal, and equipment cost is low, the utilization rate height only needs workman's operation, has both improved production efficiency and has also reduced production cost.
