Brief description of the drawings
Shown in Fig. 1 is structural representation of the invention；
Shown in Fig. 2 be importation of the present invention circuit diagram；
Shown in Fig. 3 is workflow diagram of the invention.
Specific embodiment
Below with reference to accompanying drawing of the invention, clear, complete description is carried out to the technical scheme in the embodiment of the present invention
And discussion, it is clear that as described herein is only a part of example of the invention, is not whole examples, based on the present invention
In embodiment, the every other implementation that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example, belongs to protection scope of the present invention.
For the ease of the understanding to the embodiment of the present invention, make further by taking specific embodiment as an example below in conjunction with accompanying drawing
Illustrate, and each embodiment does not constitute the restriction to the embodiment of the present invention.
As shown in figure 1, the programmable remote signalling interface of FA testers that the present invention is provided includes two parts：Importation 1 with
And process part 2.
Importation 1 is used to receive remote signals, and the remote signals of the various level to receiving carry out partial pressure, amplitude limit
And filtering, specifically include some groups of bleeder circuits 11 being sequentially connected, amplitude limiter circuit 12 and filter circuits 13.Process part
2 include analog-to-digital conversion module 21, electrical level judging module 22, anti-shaking module 23 and SOE generation modules 24.
Process part 2 can be the CPU with the converter or MCU for extending out converter.
As shown in Fig. 2 the bleeder circuit 11 used in the present embodiment includes resistance R1, resistance R2 and resistance R4；Amplitude limit
Circuit 12 is voltage-regulator diode D1, is connected in parallel on the two ends of resistance R4；Filter circuit 13 is resistance R3 and electric capacity C1, is connected in parallel on steady
The two ends of pressure diode D1.
Workflow of the invention is illustrated below：
As shown in figure 3, importation 1 receives remote signals, and remote signals to receiving carry out partial pressure, amplitude limit and
Filtering, process part 2 first reads datum and stabilization time, what analog-to-digital conversion module 21 pairs was processed by importation 1
Remote signals carry out analog-to-digital conversion and obtain remote signalling magnitude of voltage.Electrical level judging module 22 judges that the remote signalling magnitude of voltage for obtaining is electricity high
Flat, low level or inactive level, after abandoning inactive level, by the delay stabilization of anti-shaking module 23（The stabilization time can be voluntarily
Set, the present invention is not limited）, the generation of SOE generation modules 24 SOE（When switch or relay protection are acted, by the time elder generation of action
The record for sequentially carrying out afterwards）, reported to higher controller finally by bus.The remote signals of live various level are adapted to, is saved
Go on-site signal change-over circuit and wiring.
For example, remote signalling nominal level is set as 24V signals, then 24*80%=19.2V；24*60%=14.4V；
That is during remote signals level Vin >=19.2V, it is judged to high level；During remote signals level Vin≤14.4V, sentence
It is set to low level；14.4V < Vin <During 19.2V, it is judged to inactive level, does not report.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any one skilled in the art the invention discloses technical scope in, the change or replacement that can be readily occurred in,
Should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with scope of the claims
It is defined.
