Background technology
Prior art can be divided into analog quantity channel test and digital quantity lane testing according to the passage kind in the test activity of instrument control system; Can be divided into analog quantity accuracy test, analog quantity and the test of digital quantity logic function, the test of I/O response time etc. according to test-types.Although above test can realize automatic test at present, but also there is following problem: in the analog quantity accuracy test, exist number of channels many, accuracy requirement is high, each passage needs the characteristics such as multiple spot accordion seek, if adopting PCI or PXI template card tests automatically, but its measuring accuracy can not satisfy the demand of high precision measurement sometimes, but can only realize manual test if adopt high-precision test instrumentation, as: current signal is from 4mA, increase progressively take 4mA as step-length, until reach 20mA, successively decrease from 20mA take 4mA as step-length again, until reach 4mA, acquisition time to each signal is no less than 20 seconds, carries out 3 and measures circulation; If above-mentioned measurement is not tested with manually carrying out line, whole test process needs very large workload.
The utility model content
For solving the problem that in the prior art analog input and output of equipment under test is realized high-precision automatic measuring, the utility model provides a kind of High Precision Automatic test macro of analog input and output that can automatically control in any one passage that test signal is transported to equipment under test.Concrete scheme is as follows: a kind of analog quantity and switching value input/output test system, it is characterized in that, comprise proving installation and system under test (SUT), proving installation is by the high precision process test instrumentation, transfer relay is connected with system under test (SUT), described proving installation comprises the control center of sending and receiving test signal, communication serial ports with the mutual communication of high precision process test instrumentation, digital output mouth and the network interface of control transfer relay switching over, described system under test (SUT) comprises the tested passage that is connected with transfer relay, receive the control card of test data, with the network interface card of extraneous communication, wherein the network interface of proving installation is connected with the network interface card of system under test (SUT).
For the selected tested passage of convenient control: described tested passage have a plurality of and each tested passage a control port with transfer relay is corresponding respectively, described transfer relay is controlled the folding of corresponding gauge tap by the level signal that receives the digital output mouth.
Testing procedure of the present utility model, testing sequence and test report template can freely be edited and be imported by the user, need not secondary development.Under this mechanism, testing efficiency be can greatly improve, manpower and cost saved.Under original mechanism, test procedure need to pre-determine, and after tested device or test design correcting, the proving installation program also needs to rise version thereupon, and this can bring impact to testing progress; Under new mechanism, as long as the tester adjusts and imports in the test procedure test parameter in the Excel form.For example: when original testing scheme is that every passage 6 points (0,20%, 40%, 60%, 80%, 100%) measurement becomes 11 point measurements (0,10%, 20% ... 100%) time, just needn't update routine, only need a change configuration parameter to get final product.In addition, the import feature of test report template also can improve testing efficiency greatly, and improves the credibility of test data.
By original method of testing, the single channel manual test is if each passage has 6 test points, even the test of a passage of skilled tester probably needs 1-2 hour.If multiple channel test, this method will take the artificial time greatly.Adopt test macro of the present utility model, the high precision measurement of each passage can carry out automatically, and does not need manually to go wiring to come switching channel, has therefore greatly saved cost of labor.
