Abstract

The utility model discloses a timing measurement and control device for controlling on and off of a power supply, which comprises a power supply module for supplying power for a test system, a controller for controlling the whole test process, and a data output unit for outputting the test result. The controller comprises a test control input circuit electrically connected with a single chip computer, and a closed loop circuit which is formed in the way that a data conversion circuit, an interface circuit and a data acquisition circuit are connected in sequence and in circle while surrounding the single chip computer. The timing measurement and control device leads the complicated test processes to be simplified by instruments, so that a test is rapider and more accurate, and the time for maintaining an electric mechanism by a ground crew is greatly shortened.

Description

The timing measure and control device of control on/off

Technical field

The utility model relates to a kind of measure and control device at different time control on/off.

Background technology

The prior art timing mechanism is made up of motor, the rotor of being with projection, logical circuit etc.The motor drive mechanism power supply way of timing mechanism control is many, between each road power supply logical relation is arranged, and multiple-output electric power is had according to the signal of importing in the different time and selects to cut-off.The test of timing mechanism needs the tester to measure the switch off time of out-put supply with stopwatch, and once can only measure one road out-put supply.The whole test process complexity, test speed is slow, and the test duration is long, and measuring result error is big.

Summary of the invention

The purpose of this utility model is to overcome the weak point that above-mentioned prior art exists, and provides a kind of test speed faster, more accurate, can shorten the ground crew greatly and safeguard the time of motor drive mechanism and the measure and control device that can accurately measure automatically.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of timing measure and control device of controlling on/off, comprise, the power module that power supply is provided for test macro, a controller that is used to control whole test process, a data output unit that is used to output test result, it is characterized in that, described controller comprises the test control input circuit of an electrical connection single-chip microcomputer, a closed loop of forming around the data converting circuit that connects, interface circuit and data acquisition circuit successively around described single-chip microcomputer.

In the test process of whole timing mechanism, controller, is exported test result by the data output unit after test is finished by the make-and-break time that cut-offs and measure each road out-put supply of timing mechanism of control program control timing mechanism power supply.

The utility model has following beneficial effect than prior art.

The utility model adopts electronic digital control system, digitizing is the break-make of observing and controlling power supply regularly, automatically finish test control, data acquisition, data analysis and calculating, and with test result output, whole test process is simple to operate, the test duration is short, measurement result precision height.Because test macro has adopted the single-chip microcomputer with high-speed computational capability, test speed is faster, and is more accurate, makes control and measuring accuracy be greatly improved, and measuring accuracy has had qualitative leap.Can bring up to 1ms from 0.5s with having the measurement result precision now, and can regularly export, measure simultaneously all.During test, only need just can finish the test job of measured workpiece, satisfy test request with a work period.。Avoid prior art to need the measurement of one time one tunnel output, and then saved the test duration greatly, reduced the loss of measured piece working time.

The utility model is oversimplified the test process of complexity with instrument, not only shortened the time that the ground crew safeguards motor drive mechanism greatly, and can also test the timing observing and controlling of multiple different model motor drive mechanism, reduces the requirement to the tester.During test, the tester only need import the model of measured piece, and test macro just can be finished whole test job automatically, has got rid of in the existing method of testing, and the tester is because of the damage bosom of maloperation to measured piece.

Description of drawings

Further specify the utility model below in conjunction with drawings and Examples, but therefore the utility model is not limited among the described scope of embodiments.

Fig. 1 is a regularly measure and control device schematic block circuit diagram of the utility model.

Fig. 2 is Fig. 1 circuit block diagram circuit diagram.

Embodiment

In Fig. 1, described timing measure and control device mainly is made of power supply, controller, data output unit three parts.It is made up of single-chip microcomputer and peripheral circuit thereof, control circuit, data acquisition circuit etc.The controller of this timing measure and control device is the core of total system.Controller mainly comprises the test control input circuit of an electrical connection single-chip microcomputer, and one centers on single-chip microcomputer and presses the closed loop that directional ring shown in the arrow is formed around connection control transformation circuit, interface circuit, data acquisition circuit among the figure successively.Wherein said single-chip microcomputer is one to have and can carry out high-speed data and handle DATA REASONING s operation control, data analysis, the chip of logic control function.The power module that links to each other with the controller circuitry input end provides power supply for test macro in test process.The data output unit that links to each other with controller output end is the module of the test result output of test macro, and it is by showing that control refers to that circuit and LED display module form.It shows the data that slave controller transmits on request.When test, with the data that collect, constantly analyze then and computing from the variation of the output voltage data of measured piece, the result is saved in the storage unit of single-chip microcomputer inside by monitoring by data acquisition circuit for test control input circuit.And by single-chip microcomputer it is preserved, test, the data of test are analyzed and computing, by single-chip microcomputer the result is outputed to the data output unit at last, data are exported test result by display control circuit and LED display module.

In Fig. 2, the single-chip microcomputer in the controller (AT89C52) is controlled test process, and data converting circuit is made up of resistance R 2～R17 and photoisolator U2～U9.Test data passes to photoisolator U2～U9 after resistance R 2～R17 current limliting, photoisolator is passed to single-chip microcomputer after data are converted to the signal that single-chip microcomputer can discern.The data output unit is by triode Q1～Q4, charactron DS1～DS4, diode D1, resistance R 18.The cut-offfing of port controlling triode Q1～Q4 of single-chip microcomputer selected charactron DS1～DS4, choose charactron after single-chip microcomputer again video data is passed to charactron.Diode D1 directly links the port of single-chip microcomputer, is used for the indication mechanism worker and does state.

During test, require to obtain from S1～S4 button according to the tester, after test was finished, controller was exported by display control circuit and LED display module data with test result.
