Wire cutting computer online photoelectric isolation transmitter (2)

Professional knowledge:

Using the traditional answering connection is equivalent to the electrical connection between the computer and the machine tool. The disadvantages are as follows:

1. When the number is sent, the error is often stopped, and when the number of blocks is large, the transmission cannot be completed.

This is because the computer and the machine tool console are composed of integrated circuits and electronic circuits. The internal resistance is high and the interference signals are easily detected. The various machine tools on the production site are also an interference source during operation.

Interference through the grid loop affects the transmission of the program.

2, often burned computer parallel port and console interface circuit;

When the interference energy is large enough, or the power plug is often plugged in or plugged in, or the mechanical converter switch is bad, an instantaneous high voltage will be formed to attack the equipment; the more the number of machine tools, the higher the damage; the final result:

It is to replace the computer and machine console.

3. Due to the interference, the computer must be used at the closest distance to the machine tool;

The production site environment is poor, and the home computer has no measures such as dustproof, moistureproof, anti-interference, etc., so the computer failure is greatly increased.

The survey found that the above situation is very common among users.

The program transmitter is both a protector and a stable and accurate communicator. All problems on the line will be solved!

examples of success:
The opto-isolator has been installed on the following single-board machines. After testing and using, the effect is very good.
Ningbo: Fumao, Dewei, Huxing, Zhongyuan, Zhenwei, Yanmao.
Domestic fast-moving wire cutting controller production standards:
Answering the received single board/microcontroller: it is active low, the pause is D
Single board/microcontroller that receives synchronously: it is active high and the pause is D.

Response to the installation of the optoelectronic isolation board:

Interface definition:

The output port of the opto-isolator (in order not to change the original line, we make the output port of the opto-isolator as the computer print port). Insert the original 25-pin D-shape directly into the photoelectric isolation port.
