Abstract
The invention relates to a method for testing the input/output of a piece of equipment. The method for testing the input/output of the equipment comprises the following steps that: step 1, an output port of equipment to be detected is connected an input port through an input/output connecting device, and the equipment to be detected is connected with a power supply; step 2, the output port of the equipment is driven to output through a testing program matched with the equipment, the input port of the equipment receives an output signal of the output port, and the input port of the equipment transmits a received signal to the testing program so as to carry out the data analysis; and step 3, the testing program inputs a testing result to a display device connected with the equipment to be detected, and the display device displays a testing result. By adoption of the method for testing the input/output of the equipment, a testing tooling is omitted, the testing cost is reduced, the testing method is simple to operate, and the testing result can be displayed rapidly; the testing method is universal and can be used for testing input/output ports of different equipment; and the automation of the test is realized without problems of testing omission and misjudgment.
Description
Technical field
The present invention relates to a kind of method of testing, refer in particular to a kind of equipment input/output test method, be mainly used in the occasion that the industrial automation field need be tested.
Background technology
The existing equipment input/output test adopts the independent test mode, and the input test step is that the test man passes through test fixture and gives an input signal to controller, and the controller display device shows detected input, test man's judged result.
The output testing procedure is that test man's driving governor sends an output signal to test fixture, and the test man is through the displaying contents judged result on the test fixture.
Low and the easy erroneous judgement of this method of testing efficient, moreover the test man repeats the frock easy fatigue.
Summary of the invention
For overcoming the above problems, the invention provides a kind of equipment input/output test method, said a kind of equipment input/output test method may further comprise the steps:
Step 1 is connected the equipment under test energized through the output port of input and output connection with equipment under test with input port;
Step 2, by the test procedure driving arrangement output port output of matched, the equipment input port receives the output signal of output port, and the equipment input port is sent to test procedure with the signal that receives and carries out data analysis;
Step 3, test procedure is input to the display device that is connected with equipment under test with test result, and display device shows test results.
But it is a plurality of equipment input ends of output terminal cascade of equipment that equipment output end described in the further step 1 is electrically connected to the equipment input port;
Wherein, a plurality of equipment input ends of an output terminal cascade of equipment are the input item input end that staggers, and are used to prevent adjacent two input point short circuits;
Display device further also shows each input point status information, is used for underproof input point state is shown;
Further step 2 is write according to different equipment under tests with the test procedure described in the step 3;
Beneficial effect
1, saves test fixture, reduce testing cost;
2, method of testing is general, can be used for the test of distinct device input/output terminal;
3, method of testing is simple to operate, and test result shows fast;
4, test realizes robotization, test leakage can not occur, the erroneous judgement problem;
Description of drawings
Fig. 1 is a kind of equipment input/output test of the present invention method theory diagram;
Fig. 2 is the schematic flow sheet of a kind of equipment input/output test of the present invention method;
Fig. 3 is a kind of equipment input/output test of the present invention method signal indication synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing and embodiment a kind of equipment input/output test of the present invention method is elaborated:
As shown in Figure 1, at first be connected with input port through the output port of input and output connection with equipment under test, equipment under test power interface energized is connected display device simultaneously with equipment under test; Move the test procedure that is installed in the equipment under test then, test procedure drives equipment under test output port output signal, and the equipment input end receives the output signal of output port, and the while output port is sent to test procedure with the signal that receives and carries out data analysis; The last test program is input to display device with test result, and display device shows test results, and display device also shows each input point status information simultaneously, is used for underproof input point state is shown;
But a plurality of equipment input ends of output terminal cascade of described equipment are measured a plurality of input ports simultaneously, are convenient to improve testing efficiency;
A plurality of equipment input ends of an output terminal cascade of described equipment are the input item input end that staggers, and promptly output terminal adjacent input end of cascade simultaneously not is used to prevent adjacent two input point short circuits;
Like Fig. 2, test procedure is loaded in the testing apparatus, and device power-on begins to test; Test procedure drive output mouth output signal uses to connect lead connection output port and input port, is received by input interface behind the output port output signal; And feed back in the test procedure through input interface; Test procedure judges whether input interface has the signal input, as imports and normally then point out test passes, otherwise then points out test failure; Preferably, which interface no signal input test procedure can also judge.
Preferably, as shown in Figure 3, behind the test procedure drive output mouth output signal, the output port pilot lamp is bright, and prompting output is normal, and after input port received input signal, the input port pilot lamp was bright, and the prompting input is normal.
Although reference implementation example and accompanying drawing; A kind of equipment input/output test method of the present invention is illustrated; But above-mentioned disclosed content only is in order better to understand the present invention; Rather than limit the scope of claim by any way, so all according to the described structure of patent claim of the present invention, characteristic and principle do etc. change or modify, include in protection scope of the present invention.
