The problem of being unable to satisfy testing requirement.
Utility model content
The purpose of the utility model is to overcome disadvantages existing in the prior art, provide one kind and test point, function more
The ICT tester system that extension is flexible and measuring accuracy is high.
To achieve the goals above, the technical solution adopted in the utility model is as follows:
A kind of ICT tester system, including CPU, power input and output terminal and relay terminal, it is characterised in that also
Including communicated with host computer communication terminal, external connection module terminal, multiple test point extended terminal, TTL being connect with test point
Communication terminal and I2C communication terminal；Wherein, TTL communication terminal is realized communicates between external expansion module and plate；I2C is logical
Letter terminal is communicated by connecting realization with mainboard；External connection module terminal includes amplifier module terminals, ADC module terminal, constant-current source
Module terminals.
Further, the communication terminal communicated with host computer is network interface communication terminal and/or usb communication terminal.
It further, further include I2C extended terminal, for handling the communication for supporting the external expansion module of I2C.
Further, the external corresponding external connection module of external connection module terminal and between use SPI communication.
The technical solution of the utility model does not have on oneself plate so that test can be extended by modularization to increase
Function, be not required to redesign can be realized hardware capability upgrading, and support communication pattern it is more, Function Extension is flexible.Together
When can support 32 drive tests try, maximum 64 tunnel Ke Dao.It is more to test point, saves metered quantity, reduces cost.Particularly, this product
Measuring accuracy is high, resistance full accuracy ± 5m Ω, electric current full accuracy ± 5mA, good test effect.

Specific embodiment
The utility model will be further described with reference to the accompanying drawing.
Referring to attached drawing.The utility model includes the CPU1 being on circuit board one, power input and output terminal 2, relay
Device terminal 3, network interface communication terminal 4, usb communication terminal 5, TTL communication terminal 7 and expansion module terminal are in circuit board two
On test point extended terminal 6 and I2C communication terminal 8.Wherein, central processing unit of the CPU1 as control panel is equivalent to control
The brain of making sheet is responsible for resolve command and realization movement；Power input terminal can external 12V power supply adaptor, configuration power supply give
Main board power supply；Test point extends mouth terminal 6 and is used to connecting test point interface, so that providing multiple test points reduces tester instrument
The use of table.
Network interface/usb communication terminal is then for realizing the communication with host computer, so that CPU1 can receive the finger from host computer
It enables；Expansion module terminal includes amplifier module terminals 10, ADC module terminal 11 and constant-current source module terminals 12, so as to outer
Corresponding expansion module is connect, the Function Extension upgrading of product itself is realized, to adapt to different demands.TTL communication terminal 7 passes through
The module of TTL communication is supported to realize Function Extension in connection outside, or realizes communication between plates.I2C communication terminal 8 then passes through connection
Realization is communicated with mainboard.Particularly, the present embodiment further includes the I2C extended terminal 9 on circuit board one, is supported for handling
Communication, such as relay board of external expansion module of 12C etc., so that the communication for expansion module provides communication,
More flexible convenience when use.
It is ordered in use, PC machine is sent by network interface, after mainboard receives instruction, relay required for executing.Mainboard is directed to
Different product switch sampling resistance value.It is quantity that test point, which is arranged, according to product in expansion interface plate.When testing resistance value, constant-current source mould
Block exports electric current and passes through product, ADC module, and data pass through SPI communication back MCU, resistance value is calculated.When testing electric current, mention
Voltage supplied passes through product, amplifier module, sampling resistor.By the sampling resistance value and voltage of MCU control, current value is calculated.
Controller realizes the test of multi-channel test point by I2C interface and extension board communications.
It should be pointed out that the embodiments of the present invention are described above.However, the technical staff of art technology should manage
Solution, the present utility model is not limited to the above embodiments, only illustrates the principles of the present invention described in above-described embodiment,
There are many changes and improvements for the utility model also meeting under the premise of not departing from the scope of the utility model, these changes and improvements are all
It falls within the scope of the claimed invention.
