Description

A kind of electro-delay system test macro

Technical field

The present invention relates to a kind of test macro, particularly a kind of Performance Test System of electro-delay system.

Background technology

Electro-delay system (abbreviation chronotron) is a kind ofly can be widely used in field of intelligent control according to the parts of the time accurate delay control that sets.Chronotron is as the important control parts on the product, and the reliability of its action is directly connected to the result of use of product.In order to ensure the quality of electro-delay system in scientific research, production phase, in the production of electro-delay system trial-production and every process of the test, need by checkout equipment to its performance detect, delay time sets etc.

Present stage, the performance test of chronotron is powered to chronotron by the manual adjustments power supply mainly by means of testing apparatuss such as multimeter and oscillographs.Whole test process complicated operation, inefficiency, workload are big, and be very high to tester's competency profiling, the improper chronotron that causes of wiring often occurs and burn phenomenon.

Summary of the invention

The present invention finishes the complete detection to the chronotron performance as the special test equipment of electro-delay system.

The objective of the invention is to be achieved through the following technical solutions:

A kind of electro-delay system test macro, comprise AC/DC module, DC/DC module, s operation control module, address test module, communication module and a plurality of time supply module and a plurality of A/D module, wherein each electro-delay system to be tested connects an A/D module and a time supply module by test cable respectively; The input end of AC/DC module connects AC power, and output terminal is by the input end of power lead connection DC/DC module, and the output terminal of DC/DC module is connected with the s operation control module by power lead; Be connected by data line between s operation control module and address test module, communication module, each time supply module, each A/D module; Communication module is connected to industrial computer by data line and communication interface; The address test module is connected to one with reference to electro-delay system by data line.

Principle of work of the present invention is: the AC/DC module is converted to direct current with the alternating current of input, and the DC/DC module is carried out the secondary conversion with direct current, is converted to the required voltage of test macro, is the s operation control module for power supply; The s operation control module,, is tested and communication test thereby carry out the address to test the identification and the communication situation of electro-delay system to be detected to each address with reference to the variation regularly, rule of the address of electro-delay system by the control of address test module; The time supply module is used to electro-delay system to set delay time and controls power supply and the outage of test macro to electro-delay system to be measured; After the A/D module collects the output information of electro-delay system to be measured, carry out the A/D conversion and be transferred to the s operation control module, the s operation control module is carried out corresponding computing, draw delay time, voltage and the width of chronotron output, judge whether output meets the requirements, and by communication module testing result is transferred to industrial computer and shows.

Beneficial effect

Work such as the test of communication detection, address, the delay time that the present invention finishes electro-delay system automatically sets, output time test, output voltage and output pulse width test, the performance index of guaranteeing chronotron meet technical requirement, it is accurate more, quick, reliable, convenient to make the detection of electro-delay system, accelerate the Development Schedule of chronotron, guaranteed the chronotron quality.
