Abstract
The utility model relates to an electrical property comprehensive test desk. The technical problem to be solved is that: the utility model provides an electrical property comprehensive test desk which is provided with a standard sample detection device to solve problems, and test errors caused by testing equipment and human factors can be effectively avoided. The electrical property comprehensive test desk is characterized in that: the standard sample detection device which mainly comprises a test fixture, an LCR (inductance-capacitance-resistance) electric bridge, an industrial control computer, an LCD (liquid crystal display) display and printing equipment is arranged on the test desk. Due to the arrangement of the standard sample detection device, the test desk can work normally only under the condition that a standard sample test is passed, so that the test errors caused by the testing equipment and the human factors can be effectively avoided. Meanwhile, for a multi-path scanning test, because the detection device disclosed by the utility model allows single-path parameter setting, the operation is more convenient and flexible, and then a guarantee for improving the testing effect is provided.
Description
Technical field
The utility model relates to the electrical property combined test stand.
Background technology
The electrical property combined test stand is parameters such as effective instrument of special detecting electric product and device, its energy measurement resistance, inductance, insulation.As proving installation, the system accuracy of test board itself plays crucial effects to precision of test result.General test board does not have the assurance to self precision, in case depart from algnment accuracy or think that operating mistake, measurement result are difficult to guarantee accurately.
Summary of the invention
The utility model technical matters to be solved is to the problems referred to above a kind of electrical property combined test stand that has the master body pick-up unit to be provided, the test error that can effectively stop self-testing device and human factor to produce.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of electrical property combined test stand that has the master body pick-up unit is characterized in that: said test board is provided with the master body pick-up unit of mainly being made up of test fixture, LCR electric bridge, Industry Control computer, LCD display, PRN device; By RS232 communication serial ports Data transmission, realize the communication and the control of whole test board;
Said LCD display is used to provide human-computer interaction interface;
Said PRN device is used for the printing test result;
Said test fixture is used for fixing master body to be measured;
Said Industry Control computer receives input instruction, and the LCR electric bridge is carried out the parameter setting, and receive the LCR bridge test to data analyze; If test result is qualified, then test board gets into the operate as normal program, if test result is defective, then test board gets into waiting status, and test again after waiting to find the cause is passed through until the master body test, and test board could operate as normal.
For adapting to the needs of multi-channel scanning, preference is that said test fixture and LCR electric bridge are multichannel; Said pick-up unit adopts the setting of single channel parameter, and the Industry Control computer selects to get into single-path testing duty or multi-channel test duty according to input instruction.
The utility model brings following beneficial effect:
Owing to be provided with the master body pick-up unit, only under the situation that the master body test is passed through, test board ability operate as normal can effectively stop the test error of self-testing device and human factor generation.For the multi-channel scanning test, because this pick-up unit can the single channel parameter be provided with, it is convenient, flexible especially to operate simultaneously, for improving test efficacy guarantee is provided.
Description of drawings
Fig. 1 is the system architecture synoptic diagram of the utility model.
Fig. 2 is the utility model proving installation synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
Referring to Fig. 1, the master body pick-up unit of present embodiment mainly comprises five drive test trial works dress, LCR multichannel electric bridge, Industry Control computer, LCD display, PRN device; By RS232 communication serial ports Data transmission, realize communication and control.
Before test board is launched, must test master body (master body: be exactly exemplar) than the high level accuracy measuring apparatus of this test board.If test result is qualified, then test board gets into the operate as normal program, if test result is defective, then test board gets into waiting status, and test again after waiting to find the cause is passed through until the master body test, and test board could operate as normal.
This test board adopts the setting of single channel parameter, as can only testing the accurate exemplar of a road sign, opens a drive test trial work and does, and also can test several roads (maximum five tunnel) master body, opens several roads (maximum five tunnel) test job simultaneously, and it is convenient, flexible to operate.
Among Fig. 2: 1 is master body; 2 is test fixture.
The master body testing process of this test board is following:
After the start of step 1. electric performance test platform, LCD display shows the Windows operation interface, and system gets into the test SBR.
Step 2. installs tested master body on test fixture.
Step 3. is the hit testing icon on operation interface, and draw ejection master body test parameter dialog box is set on the test circle.
Step 4. correctly sets the parameter (numerical value and the positive and negative deviation value that comprise standard specimen) of master body, the hit testing button, and system begins master body is tested; The test parameter of master body is resistance and inductance value and other value.
Step 5. is after the correct data of testing master body, and system formally gets into test procedure, gets into test interface.
The data that step 6. arrives when system testing and the data of master body are inconsistent, and system changes holding state at once, can not carry out normal test job.
When step 7. needs the electric performance test platform to start once more, the crawl reboot button.
After the step 8. system recovery master body test mode, the process of repeating step 3～step 6.
With the above, this test board can be realized the multi-channel scanning test, and the master body method of testing on each road as stated.
These embodiment be interpreted as only being used to the utility model is described and be not used in the restriction the utility model protection domain.After the content of having read the utility model record, those skilled in the art can do various changes or modification to the utility model, and these equivalences change and modification falls into the utility model claim institute restricted portion equally.
