Description

Ion Generator with Remote Monitoring Function via Internet {.}

The present invention relates to an ion generating device used as an antistatic device in a semiconductor factory or a textile factory. More specifically, it is possible to monitor various status information generated in the ion generating device through the Internet by adding the Internet function to the ion generating device. The city has made remote control possible via the Internet.

When managing after installation, the manager had to manage the status and condition of the ion generator directly on the site, and the manager adjusted the amount of ions by changing the voltage level by mechanical operation. Therefore, when the ion generating device is installed, the generation time and amount of ions are initialized to match the surrounding environment, and there is a hassle of having to re-initialize as the surrounding environment is changed or an inhibitor of ion generation occurs when used for a long time. Therefore, there is a need for an ion generator capable of automatically adjusting the amount of ions.

As for the management of the ion generator, hundreds of ion generators are installed in each line in the semiconductor factory. To manage this, the administrator has to check the site where the ion generator is installed and check it. The manager had to plan and manage the ion generator selection and inspection time, cleaning the ion generator pins, and initializing the ion generation ratio. Thus, a more efficient method for managing ion generators has emerged.

The present invention is a method for automatically adjusting the generation rate of the anion and cation of the ion generator, which was only manually controlled as described above, the introduction of a pulse width modulation control method that can be remotely controlled by a program and management of the ion generator It is aimed at adding Internet function to change inefficient management method in aspect.
