Description
Technical field
The present invention relates to electric parameters to examine and determine field, specifically about a kind of for carrying out comprehensive self-test to electric parameter
Electrical parameter calibrating installation Integrated Self method.
Background technique
It is also more and more to the parameter request of verification system as electrical parameter special test equipment type is more and more.
According to verifying process flow, verification system will carry out function self-test before starting calibrating, it is ensured that verification system is correctly reliable.
In order to improve the verification system localization rate of parts and components, the various test boards of independent research are emphasized, usual various test boards are removed
Has basic test function, it is also necessary to have independent self-checking function, however the independent self-checking function of various test boards is not only
Self-test low efficiency, and development amount is big, or even can encounter function mostly with board limited area the problem of conflict.
Summary of the invention
It is short for the R&D cycle of above-mentioned special test equipment verification system, design objective weight problem, the purpose of the present invention
It is to provide a kind of electrical parameter calibrating installation Integrated Self method, which raises the design efficiency of verification system, reduces independently certainly
Workload, period and the cost of checking functions exploitation, comprehensive analysis and the test resource having using verification system, and realize to inspection
Determine system and carries out system-level self-test.
To achieve the above object, the present invention takes following technical scheme: electrical parameter calibrating installation Integrated Self method,
The following steps are included: 1) channel switch card is arranged: channel switch card includes that several lateral switching channels and several longitudinal switchings are logical
Road；2) verification system includes the test board of multichannel；3) test board in each channel is connect with lateral switching channel respectively,
Meanwhile the test board in each channel is also connect with longitudinal switching channel respectively；4) the horizontal and vertical of the joint passage switch card is set
It sets, the test board in each channel is passed through into lateral switching channel and longitudinal switching channel carries out self-test or mutually inspection.
Further, in the step 1), lateral switching channel and longitudinal switching channel constitute fenestral fabric.
Further, in the step 1), control switch is provided with positioned at each switching channel inlet.
Further, in the step 4), the survey in each channel is realized using the control switch that switching channel inlet is arranged in
The self-test of test plate (panel) card or mutually inspection.
Further, in the step 2), test board includes DC voltage standard, DC current standard source, direct current
Pressure measurement and DC current measurement board.
The invention adopts the above technical scheme, which has the following advantages: the present invention is by channel switched design, not
Under the premise of influencing verification system calibrating special test equipment, realizes the system level design of verification system self-test, improve calibrating
Efficiency accelerates development cycle and human cost.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention.
Specific embodiment
The present invention is described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figure 1, the present invention provides a kind of electrical parameter calibrating installation Integrated Self method comprising following steps:
1) channel switch card is arranged: channel switch card includes several lateral switching channels and several longitudinal switching channels, cross
Fenestral fabric is constituted to switching channel and longitudinal switching channel.Wherein, control is provided with positioned at each switching channel inlet
System switch.
2) according to the statistics to verification system conventional electrical parameter, the test board of multichannel: DC voltage is generally included
The boards such as standard source, DC current standard source, DC voltage measurement and DC current measurement.
3) test board in each channel is connect with lateral switching channel respectively, meanwhile, the test board in each channel is also divided
It is not connect with longitudinal switching channel；
4) the horizontal and vertical setting of the joint passage switch card, and utilize the control switch that switching channel inlet is set
The test board in each channel is passed through into lateral switching channel and longitudinal switching channel carries out self-test or mutually inspection, such as can be by direct current
Voltage source board and DC voltage measurement board are mutually examined, and DC voltage and current standard source board and DC current measurement board is mutual
Inspection, every piece of test board is just not necessarily to the corresponding self-checking function of independent design, reduce the workload of independent self-checking function exploitation, the period and
Cost.
Embodiment:
As shown in Figure 1, with DC voltage standard board, DC current standard source board, DC voltage measurement board and
For DC current measurement board, four pieces of board signals are connected respectively to the horizontal and vertical both ends of channel switch card, work as inspection
When determining special test system, according to special test system needs, four pieces of board signals is switched to respective channel 1- channel n and are carried out
Calibrating is not necessarily to the individually designed self-test kinetic energy of every piece of board when self-test, and setting A1, A2, K1, K2 are closed the switch, and direct current is arranged
Standard source output is pressed, judges whether the self-test of two boards card is qualified according to dc voltage measurements, similarly, B1, B2, L1, L2 are set
It closes the switch, setting DC current standard source exports, and judges whether corresponding two boards card self-test closes according to DC current measures
Lattice.
The various embodiments described above are merely to illustrate the present invention, and each step may be changed, in the technology of the present invention side
On the basis of case, the improvement and equivalents that all principles according to the present invention carry out separate step should not be excluded in the present invention
Protection scope except.
